Electric slicer foldable into drawer - has automatic switch preventing motor operating with slicer in folded-down position

With its L-shaped positioning plate taken off and its cutter section swung down the machine is ready to be lowered into the drawer that houses it. In this position the cutter is particularly easily accessible for cleaning and servicing. To prevent the motor being started inadvertently in this position, (in case the instructions to remove the plug before cleaning the cutter have not been observed) an automatic safety switch is put in the circuit. This consists of an almost horizontal tube mounted in the cutter section and containing a blob of mercury which moves to break the circuit within 5 deg. - 10 deg. of that section leaving the upright position.

Apparatus and methods for z-axis control and collision detection and recovery for waterjet cutting systems

This invention relates to apparatus and methods for z-axis control and collision detection and recovery for waterjet and abrasive-jet cutting systems. In one embodiment, an apparatus includes a linear rail, a slide member coupleable to a cutting head and slideably coupled to the linear rail, at least one actuator having a first end coupled to the slide member and a second end fixed with respect to the linear rail, a position sensor, and a controller. The actuator provides an adjustable support force that supports the weight of the cutting head, allowing the cutting head to be controllably positioned at a desired height above the workpiece. The actuator may include a pneumatic cylinder, or alternately, a linear motor. In another aspect, an apparatus includes a first mount member coupleable to a controllably positionable mounting surface of the waterjet cutting system, a second mount member coupleable to the cutting head and disengageably coupled to the first mount member, and a sensing circuit having a plurality of first conductive elements disposed on the first mount member and a plurality of second conductive elements disposed on the second mount member. In the event of a collision between the cutting head and an obstruction, the second mount member disengages from the first mount member to prevent breakage of the cutting head. Following the collision, the second mount member is quickly and easily re-engaged with the first mount member without time-consuming re-calibration. In one embodiment, re-engagement of the second end first mount members is automatically performed by a biasing member.

KITCHEN PROCESSOR CONTAINING A BOWL 16 CONTAINING A TOOL 18 MOUNTED ON A VERTICAL AXIS 14 DRIVEN BY A MOTOR 6 AND SAFETY MEANS TO PREVENT THE STARTING OF THE MOTOR UNTIL THE BOWL IS LOCKED ON A BASE 2 AND QUICKLY 'A COVER 34 IS NOT LOCKED ON THE BOWL 16. THESE SAFETY MEANS INCLUDE TWO PERMANENT MAGNETS 40, 44 DOORS RESPECTIVELY BY THE BOWL AND THE BASE, INSERTED IN THE MOTOR CONTROL CIRCUIT AND EACH DIVIDED IN ASYMETRIC QUADRANTS PROVIDED WITH 'A MAGNETIC POLE, THE MOTOR CONTROL IS ONLY POSSIBLE WHEN THE BOWL AND THE COVER ARE PROPERLY LOCKED RESPECTIVELY AND THE TWO MAGNETS EXACTLY FACING EACH OTHER.

Improved safety attachment for cutting machines

Protective circuit for band saw cutter - has balancing circuit with complex voltage divider with capacitive components

The protective circuit for a band saw cutter produces signals for automatic braking of the electric drive motor. A balancing circuit controls the driving and braking circuit and comprises a complex voltage divider with capacitive components. The circuit is loaded by an oscillator voltage and is connected via a first pulse former to the first input of a coincidence circuit. The second input is connected via a second pulse former with the oscillator voltage. Within the complex voltage divider, resistances are connected in parallel with the condensers. The two inputs of a sum-and-difference amplifier are connected to both parts of the voltage divider.

Side cutters with injury protection

A safety device in a platen press for processing flat workpieces

Protective system for user of powered cutting tools

The protective system operates with powered cutting tools to prevent injury to the user. The tool has cutters (2) driven by a motor (3). The power supply (5,7) to the motor is controlled by a switch (4). The switch can be operated by an electronic safety circuit (9). The user covers the part of the body to be protected with a conductive metal mesh, for example a chain mail glove to protect the hand. The mesh (6) is connected to the negative side of the supply, while an auxiliary connection is made between the positive side of the supply and the tool. An electronic circuit (9) detects closure of the circuit through the tool and mesh caused by the tool coming into contact with the mesh.
