Abstract: A device reducing the deleterious torque in a shock absorbing, rotary drive coupling unit used with a rotary mine drilling machine comprising: a drive plate connectable to a drive shaft of the rotary drilling machine, a driven plate connectable to a driven shaft which has a drill bit, a center portion for coupling the drive plate to the driven plate wherein the center portion includes a deformable shock, vibration and torque-absorbing member, and torque-relief means comprised of a first engagement member(s) connectable to the drive plate and a second engagement member(s) connectable to the driven plate. When the drill bit snags or jams during the operation of the rotary drilling machine, the torque-absorbing member deforms and absorbs some of the torque generated therefrom.

Abstract: A plasma melting furnace has a melting chamber having an anode torch and a cathode torch made of graphite and having a electric conductor disposed on the bottom thereof. When the furnace is operated, the anode torch, having an inflow of electrons, which forms an unstable plasma arc is contacted with the electric conductor and is not used, while the cathode torch, having an outflow of electrons, which forms a stable plasma arc, is utilized for heating, whereby the furnace can be stably and continuously operated. Thus, since the cathode torch which is used is not heated so much and the anode torch, which is liable to be heated to a great degree, is not used, the electrode consumption rate can be greatly reduced.

Abstract: A working protection cover 1, 8 for preventing a vehicle body from becoming damaged during an automobile assembly line operation is free from the possibility of easily slipping off position upon mere contact of an operator with the cover, and has good durability. The working protection cover 1, 8 comprises a thermoplastic resin sheet 9 and a cloth-made sheet 10 bonded to the back of the thermoplastic resin sheet 9. The working protection cover 1, 8 has a non-slip tape 17 bonded to the back thereof, the non-slip tape 17 being made from a foam material made from a polyolefin resin and a synthetic rubber in combination. The working protection cover 1, 8 is fitted with a locking element 24, 40 for locking the cover 1, 8 to a vehicle body.

Abstract: A deep fat fryer includes a controller operatively connected to a heating element for controlling the operation thereof to apply heat to a cooking chamber. A temperature sensor is disposed in the cooking chamber for measuring the temperature in the cooking chamber and communicating the same to the controller. The controller selectively operates the heating means to apply heat to the cooking chamber. Utilizing the output of the temperature sensor, the controller automatically determines whether the medium contained in the cooking chamber is water, liquid shortening or solid shortening or whether the cooking chamber is empty.

Abstract: A flooring adapter device for providing a transitional flooring surface between two flooring materials of different heights. The flooring adapter device includes a generally planar central portion which is sloped relative to a base portion. The sloped central portion provides a surface having a gradual rise (or descent) between the two flooring surface materials joined by the flooring adapter device.

Abstract: A welding apparatus is provided which includes a rail member 5 installed along a side and a corner portion of a steel frame post, a pinion 46 mounted to a horizontally movable shifting member 50 such that even at the corner portion of the steel frame post 1 the pinion 46 is constantly held in mesh engagement with a rack 6 disposed on a side of the rail member 5, and a position holding roller 57 for guiding the shifting member 50 in a horizontal direction so that the distance between the rack 6 and the pinion 46 is kept constant. During the movement of the carriage, the distance between the rack and the pinion is kept constant to enable welding operations to be performed in succession with respect to side and corner portions of the steel frame post. Therefore, after a face-to-face welding operation at one side is completed, such a welding operation at the other side may be carried out without the necessity of removing the carriage from the rail member.

Abstract: A sensing device comprised of a sensing circuit which changes its operating characteristics when an object comes near it. The sensing circuit produces a change in output voltage proportional to the change in relative distance between the sensing circuit and an object. The actual output voltage is a function of both target distance and control circuit input voltage. The control circuit includes a comparator for comparing the steady state output voltage to a reference voltage and adjustment system for adjusting the input voltage to change the steady state output voltage such that the steady state output voltage approximately equals the reference voltage. The control circuit reacts only to reductions in the steady state output voltage, indicative of mechanical wear, and not to increases in output voltage, indicative of currency thickness measurement.

Abstract: An electronic control system for controlling a heating apparatus. The control system accurately controls the temperature of a medium, while minimizing the wear of heating element components.

Abstract: A hypodermic fluid dispenser and a collapsible body for the hypodermic fluid, with a hypodermic needle injecting the fluid once sufficient pressure is applied to collapse the body. There is also disclosed an electrical hypodermic fluid dispenser having a reusable, rechargeable power source, and a reservoir from which hypodermic fluid can be withdrawn for injection through a single injection orifice.

Abstract: A railway vehicle having a variable trim body, comprising two bogies with respective swinging transverse members pivotally connected to the body, and a control system for controlling roll of the body about its longitudinal axis, by use of linear actuators interposed between the swinging transverse members and the opposite sides of the body and operated through a regulation electronic unit connected to a first transducer device detecting the non-compensated centrifugal acceleration acting on the body, and to a second transducer device comprising at least two angular transducers for detecting the momentary relative angle between each swinging transverse member and the body.

Abstract: A body roll control system in a railway vehicle with a variable trim body, wherein two pairs of fluid pressure linear actuators are substantially vertically interposed between the body and the opposite sides of two bogies. The control system comprises a single valve unit in common to both actuator pairs, and the actuator of the two pairs placed in correspondence of one side and, respectively, of the other side of the body are connected to each other and with the valve unit through respective common fluid lines.

Abstract: The invention relates to a composite membrane with a porous polymer support layer and a polymer top layer, whereby the porous polymer support layer is of polyacrylonitrile (PAN), polyacrylamide, polyetheretherketone (PEEK), polyetherketone (PEK), polysulfon or polyethersulfon, whereas the polymer top layer is a dense layer comprising polyvinyl chloride with selective water permeability.
