Abstract: MULTIFOCAL HOLOGRAPHIC SCANNING APPARATUS                AND SYSTEM            Abstract of the Disclosure A holographic scanning system for scanning bar code indicia is disclosed in which the light beam of a laser is directed to a first set of holograms located on a single rotating disc in which each hologram will generate an individual scan beam having a slightly different focal length and direction angle from that of the other holograms.  The generated scanning beams are directed on a target area through which passes a label or object bearing a bar code indicia.  Each of the scan beams is projected in an overlapping relationship on the target area, thereby providing an enhanced depth of focus enabling a more effective reading operation.  The light reflected from the bar code indicia is picked up by a second set of holograms mounted on the rotating disc and focused at a point at which is located an optical detector for use in reading the bar code.

Abstract: Abstract of the Disclosure A power supply for electric arc welding, particularly gas tungsten arc welding, is described.  The supply operates from conventional, alternating potential, and provides either a direct current or an alternating current with a rectangular wave shape to a load.  The supply includes an input trans-former, and two current paths, each of which includes an inductor and a controlled rectifier.  A control circuit initiates conduction of the rectifiers at appropriate times selected to obtain the desired load current.  In preferred embodiments, the control circuit includes differential amplifiers which enable comparison of the output current to a control current, adjustment of the ratio of the currents in the two current paths, and adjustment of the gain and time constant of the control circuit.

Abstract: ABSTRACT             This invention relates to gas meters and, in particular, four chamber gas meters in which the diaphragms are directly connected to the tangent by means of which the valve or valves which control the flow of gas from the inlet into the chambers and from the chambers to the outlet, are operated.  The gas meter is comprised of two spaced diaphragm compartments each containing a diaphragm which divides its respective compartment into inner and outer discrete measuring chambers.  A control chamber is pressure sealed with respect to the measuring chambers and the exterior of the meter. Discrete passage apparatus extends between each of the measuring chambers and the control chamber. Inlet passage apparatus extends between the control chamber and the inlet to the meter.  Outlet passage apparatus extends between the control chamber and the outlet of the meter.  Valve apparatus is located within the control chamber, rotatable shaft apparatus for a first portion enclosed within the control chamber and is drive connected with the valve apparatus and has a second portion which extends exteriorly of the control chamber.  Crank apparatus is drive connected with the second portion of the shaft apparatus.  Connecting apparatus connects the diaphragms to the crank apparatus whereby upon concomitant reciprocating movement of the diaphragms the valve apparatus will be driven to connect each of the discrete passages sequentially with the inlet passage apparatus and the outlet passage apparatus.

Abstract: METHOD AND APPARATUS FOR MEASUREMENTS OF CHANNEL OPERATION                         ABSTRACT            A channel for a data processing system is provided with a time of day clock that is synchronized with the time of day clock of the associated central processor. Both the central processor and the channel processor record times of particular events, and the channel uses these times to calculate two times called Function Pending and Function Active.  Both times begin when the central processor executes an instruction to begin an I/O operation.  Function Pending ends when the channel has made successful initial selection.  This time shows delays by the channel processor in scheduling the channel resources for I/O operations.  Function Active ends at Channel End.  A new instruction, Set Channel Monitor, enables or disables these measurements.  An information block for each subchannel defines one of several measurement modes for a subchannel or disables the subchannel from measurement.

Abstract: ABSTRACT OF THE DISCLOSURE         A disc-like cover for frying pans or like vessels, having a steam-permeable filter surface made of fibrous filter element is shaped to be produced very simply and as a disposable item can be easily destroyed after a single use.  According to the invention the steam-permeable areas of the filter are de-limited at least in part by thickened areas within the filter material these thickened areas, interlocked with the filter, have plastic additions, the pores of the filter serve especial-ly as locking cavities for the addition.  These thickened areas are stiffer than the steam-permeable areas and thus render the disc-like cover as a whole more stable with regard to shape.          In addition, conventional radial arms of one width are weakened in cross-section by cuts that extend from one of their edges and the adhesive joint between the radial arm and filter sur-face is reduced in the area of weaker cross-section.  At least two cuts are made in each radial arm, each extending from one edge, all the cuts being parallel.

Abstract: Abstract of the Disclosure A die cylinder assembly is designed for use in an environment which has contaminants outside the assembly.      The die cylinder assembly includes a piston disposed in a cylinder and having an outer end surface.  The piston is moved in one direction by forces applied to the outer end surface of the piston.  The piston is moved in an opposite direction by a working fluid pressure in a head end chamber of the cylinder.  The cylinder includes a rod end variable volume chamber which is connected in fluid communication, through a first passage in the piston rod, with a third chamber located in the piston rod.  The fluid pressure in the rod end chamber is always maintained at least as great as ambient fluid pressure to prevent contaminants from entering the rod end chamber.  A check valve in a second passage admits outside air to the third chamber when fluid pressure in the third chamber drops below ambient pressure.  A relief valve vents the third chamber if fluid pressure therein becomes too high. The assembly has an improved piston-cylinder seal for preventing fluid flow between the rod end chamber and the outside even when the piston rod is tilted relative to the cylinder.
