Abstract: ABSTRACT                Road/rail vehicle A road/rail vehicle (1) has road wheels (7) and rail wheels (4- 5) which are movable between extended and retracted positions (as illustrated). The vehicle has selectively engageable first and second drive means for transmitting power from the engine to the road and rail wheels respectively. When the vehicle is in a rail going condition with its rail wheels in their extended positions the road wheels are maintained out of contact with the track rails by deflection restriction means operable on the suspension means of the road wheels (7).   The vehicle also has a sub-frame at the rear to which the rear rail wheels (5) and the bodies of lifting jacks (9) of auxiliary apparatus are mounted.   The sub-frame is vertically movable on slides (13).   The auxil-iary apparatus may include means for tamping, packing, levelling and/or lining.

Abstract: (Case No. 7021) ABSTRACT OF THE DISCLOSURE  A non-linear filter which reduces high signal-to-noise ratio due to sharp and erratic variations in an input signal by charging a storage capacitor through a long time constant charging circuit so that the stored signal level lags an increasing input.  A parallel path with a much lower time constant rapidly discharges the capacitor upon input decreases, so that the stored signal matches the more accurate lower input signal level.  A practical application is for car space measurements in railroad yard storage tracks to substan-tially reduce erratic distance measurements due to poor shunt-ing under moving cars.  The distance measurement signal is applied through an integrator network to a first of four FET operational amplifiers, whose input and feedback networks have selected time constants to substantially filter out background noise due to the track signal frequency.  The second amplifier provides a perfect rectifier for the dis-charge of the storage capacitor through a low time constant path when the input signal decreases.  A T-shaped resistor network and the third amplifier provide longer time constants to delay the charging of the storage capacitor, in accordance with an increasing output level from the first amplifier, without requiring excessively large component values.  A final amplifier provides a representative distance measurement signal output from the storage capacitor from which noise due to poor shunting by a moving car is largely eliminated for increased accuracy.

Abstract: DIGITAL WELDER CONTROL SYSTEM                    Abstract of the Disclosure A digital welder control system for controlling a portable gun welder of the type used in the automotive industry on an assembly line.  An 8 bit microprocessor is the main control element of the system.  The known cycle time of the microprocessor is used to generate a real time delay which in turn is used to generate a digital phase shift heat control.  RAM locations in the microprocessor are used to store medium constants of the welding sequence which were previously stored, in prior art controls, in the position of tap switches or thumbwheel switches.  The controller provides diagnostics for six common problems often encountered by welder control systems such as override timeout, half cycling, transformer temperature rises, a low water flow, a shorted SCR, and a change in the heat settings.  The controller also provides a maintenance interval counter and compensator control having a four-step stepper.  The stepper control is used to automatically increase the weld heat after a preset number of welds to compensate for electrode mushrooming.  The controller also checks the setting of address and data thumbwheels to prevent incorrect entries into the welding sequence.  The controller also permits entry of data only into RAM locations which are used in the normal sequence of the welder.  The controller also utilizes serial communication between a sequence module used to program the microprocessor and the microprocessor to economize on the number of drivers and receivers required and to reduce the power requirements of the controller.

Abstract: ABSTRACT OF THE INVENTION    A free-piston Stirling engine usable as a heat pump has a closed vessel filled with helium working gas which is heated at the bottom end and cooled at the top end.  The vessel contains a displacer sup-ported for axial reciprocal oscillation on a gas spring post mounted on the vessel.  The displacer shuttles the working gas from end to end in the ves-sel, alternately heating and cooling the gas.  The vessel is sealed with a flexible diaphragm which flexes in response to the pressure wave generated in the vessel as the working gas is alternately heated and cooled.  When the diaphragm flexes, it displaces hydraulic fluid in a hydraulic chamber and drives a power piston for driving a linear alternator and a gas compressor.  A gas spring operating on a second hydraulic cylinder on the other side of the power pis-ton stores part of the energy of the piston stroke and returns it for the return stroke. Controls are provided for balancing and controlling the hydraulic fluid pressure, for starting the Stirling engine, and for modulating its power output,

Abstract: SWITCH WITH SLIDING CONTACTOR            Abstract of the Disclosure A switch construction including opposed contacts posi-tioned on a base and a bridging sliding contactor slidable be-tween different switch positions.  The design of the contacts on the base includes an upper section that defines a first surface engageable by a tab formed on the sliding contactor, and second surface blade portions which provide engagement with wing sections defined on opposite sides of a tab section formed on the sliding contactor.  Resilient means press the sliding contactor against this upper section in a fashion such that the wing sections slide over the second surface portions and the tab section engages the first surface portions.  The separ-ate engagement of the tab and wing sections provide separate available current paths for the switch; and since either the tab or the wing sections may engage the contact first, arcing is confined to this initial contact area during switch closure.          The other section may then act as an inclined plane during switch closure to help lift off the arcing section away from the initial contact area after arcing occurs.  The section that is engaged in the maintained state of the switch is thus a clean contact area at which no arcing has occurred.  Similarly, upon opening of the switch circuit the initial contact point is also the last point of the sliding contactor that contacts the stationary contact, and thus arcing is again confined to this area.

Abstract: PHO 81.501                                   15.6.1981 ABSTRACT:          "Slicing cutter for kitchen food-cutting appliance".    A rotary slicing cutter for a kitchen food-cutting appliance comprises a disc (4) formed on one side with raised portions (15), for example in the form of ridges, which provide a surface for supporting and po-sitioning the food during operation of the cutter, the surface lying in a first plane (16) perpendicular to the central axis of the disc. Fixed on the same side of the disc over an opening (7) or openings therein, and on an unraised portion or portions of the disc, is a cutter blade (3) or plurality of blades, the cutting edge (9) or edges of which lies or lie in a second plane (17) per-pendicular to the central axis of the disc. The distance between the two planes determines the thickness of the slices cut by the blade or blades. Different slice thick-nesses can be obtained by the use of a set of inter-changeable cutters of the above construction which differ from one another only in the height of the raised portions on the disc of each cutter and therefore in the distance between the first and second planes. (Figures 1 and 2).
