Potable rainwater collecting apparatus

POTABLE RAINWATER COLLECTING APPARATUS

The invention provides apparatus for use in collecting potable rainwater including: a trough member (10) having a dished surface (11) and adapted to receive rainwater when operatively disposed; a discharge outlet (12) in said trough member (10) in that part thereof (13) which is lowermost or near lowermost when the trough member is operatively disposed; delivery tube means (15) connected to said discharge outlet (12) for conveying received rainwater for passage to storage or distribution means; mounting frame means (18) whereby said trough member (10) may be mounted in a rain-receiving location, and tilt means (22) operatively connecting said trough member (10) to said mounting frame means (18); the parts being so made and arranged that said tilt means (22) will enable said trough member (10) to be moved between said operative disposition in which rainwater is received and then delivered via said discharge outlet (12) and said delivery tube means (15) and an inoperative disposition in which ...

Potable rainwater collecting apparatus

The intention provides apparatus for use in collecting potable rainwater including: a trough member (10) having a dished surface (11) and adapted to receive rainwater when operatively disposed; a discharge outlet (12) in said trough member (10) in that part thereof (13) which is lowermost or near lowermost when the trough member is operatively disposed; delivery tube means (15) connected to said discharge outlet (12) for conveying received rainwater for passage to storage or distribution means; mounting frame means (18) whereby said trough member (10) may be mounted in rain-receiving location, and tilt means (22) operatively connecting said trough member (10) to said mounting frame means (18); the parts being so made and arranged that said tilt means (22) will enable said trough member (10) to be moved between said operative disposition in which rainwater is received and then delivered via said discharge outlet (12) and said delivery tube means (15) and an inoperative disposition in which it has been tilted from said operative disposition to one of such inverted, semi-inverted or inclined nature that said dished trough surface (11) will not support liquid or solid materials. <IMAGE>

Improvements in or relating to an epicyclic change-speed gearing and controls therefor

1,206,933. Variable-ratio gears; changespeed control. AUTO TRANSMISSIONS Ltd. 1 Nov., 1967 [1 Nov., 1966], No. 48801/66. Headings F2C and F2D. A vehicle transmission is optionally fully automatic or manually controlled and provides five forward ratios and reverse. Gearing.-A planetary gear has an input shaft 27 driven by the turbine of a hydrodynamic coupling or converter and comprises a rear sun 71 on a shaft 65 coupled to the input shaft by a one-way clutch 95 so that the sun 71 cannot rotate faster than the input shaft, the clutch 95 being bridgeable by a multi-plate clutch 74. A centre sun 80 on a sleeve 76 is connectable to the input shaft by a disengageable one-way clutch 83, and a front sun 112 is carried by a sleeve 108 which is splined to an axially movable doubleconed friction clutch/brake member 114 which is selectively engageable with a clutch surface 116 on the input shaft and engageable with a brake member 106 for stationing the front sun 112. A planet carrier 63 is fast with an output shaft 46 and has intermeshing planets 148 and 142; planet 148 meshes the centre sun 80 and a ring gear 139 which is stationable by a brake 135, and is fast with a planet 149 meshing the rear sun 71. The planet 142 is fast with a planet 140 meshing the front sun 112. First gear is obtained with the ring 139 stationary and the centre sun 80 driven by way of the over-running clutch 83, second gear with ring 139 stationary and the rear sun 71 driven by way of the bridging clutch 74, third gear with the front sun 112 stationed by the brake 106, 114 and with the centre sun 80 driven through the over-running clutch 83, fourth gear with the front sun stationed and the clutch 74 engaged to drive the rear sun, and fifth, direct drive, with the clutches 74 and 114, 116 engaged so that both the front and rear suns are clutched to the input shaft. For reverse drive the front sun 112 is driven through the clutch 114, 116 and the ring 139 is stationed. One-way clutch 83 has a ...

Sludge treatment

A gas bubble generator (1) for mixing or promoting turbulence in a liquid medium (2), particularly sewage or effluent, comprises a collector (3) for gas which collector is submerged in the medium (2) and has an exit (5) from which leads a pipe (4) with a curved part (9) between the exit (5) and a free end (8) of the pipe from which gas escapes as a bubble to surrounding liquid medium (2). The free end (8) is spaced laterally from the exit (5), and the curva­ture of the curved part (9) is 135° so that there is no obstruction of the pipe (4) by the medium (2).
