Abstract: HYDRAULIC CONTROL SYSTEM          Abstract of the Disclosure A hydraulic control system is provided including a fluid reservoir, a variable displacement pump having a fluid input in fluid communication with the reservoir and having a fluid output, and a fluid actuated displacement control mecha-nism for controlling the displacement of the pump.  A control valve is placed in fluid communication with the fluid output of the variable displacement pump and with the reservoir and is adapted to control the flow of fluid to a fluid actuated device.  The control valve includes means for developing a control pressure signal.  A sensor valve is placed in fluid communication with the control pressure signal, the displace-ment control mechanism, and the reservoir for placing the con-trol pressure signal in fluid communication with the displace-ment control mechanism or for placing the displacement control mechanism in fluid communication with the reservoir, in response to the magnitude of the pressure control signal, thereby control-ling the displacement of the pump in response to the magnitude of the pressure control signal.  The control valve includes a plurality of plungers for controlling the flow of fluid between a central passageway, a supply manifold, service ports, and an exhaust manifold.  each of the plungers includes a plurality of metering notches for providing the only continuous flow path through the central passageway between the inlet and the exhaust port when the plungers are between a neutral position and an operating position. The fluid actuated displacement control mechanism is mechanically connected to the pump for controlling its displacement.  The mechanism is provided with a fluid passage for placing the mechanism in fluid communication with the pump drain.  The fluid passage includes a flow restriction which varies in response to the position of the mechanism.

Abstract: ABSTRACT         A high intensity radiant electric space heater, suitable for rooms with low ceilings.   The heater is designed for mounting to the ceiling near the wall.         The heater consists of a reflector and several high temperature elements.   The elements are mounted end to end.         The elements are energized in sequence.   Each individual element is glowing for a short part of the cycle.   The practical effect is similar to a beam of high intensity heatrays travelling across the room, resting in each part of the room a short time before continuing its travel.         The heat output is modulated by controlling the length of this dwell time.   Elements remain at optimum radiation temperature.         Control can be achieved with electro-mechanical or solid state electronic devices.         The visual effect is that of a valance with a softly glowing line moving slowly along it.

Abstract: 16               48,347 ABSTRACT OF THE DISCLOSURE          Precise placement of one or more coiled fila-ments within the envelope of a miniature type incandescent lamp is achieved by positioning the coil legs in end-to-end abutting relationship with the respective lead wires and locking them in such junctured relationship with metal tubes that enclose and are fastened to the abutted end portions of the mated lead wires and coil legs and thus couple the members together.  The coupling tubes are first secured to the lead wires so that their open ends provide tubular pockets which receive the coil legs and guide them into the proper mounting position on the lead wires.  The open ends of the tubes are then hot-clamped around the associated coil legs, thereby mechanically and electrical-ly joining the members together in operative relationship. The invention is particularly useful in the production of miniature halogen-cycle type incandescent lamps that are employed as  compact  light sources in sealed-beam auto-motive lamps which require one or more precisely-mounted filaments.

Abstract: ABSTRACT The invention relates to an electrostatic copying apparatus of type in which an electrostatic latent image is developed on the surface of a photosensitive member by applying a fine powdery developer to the electrostatic latent image to form a toner image which is transferred to a receptor sheet after which the remaining electrostatic charge on the photosensitive member is eliminated and the photosensitive member cleaned of excess developer.  The cleaning step is carried out, according to the invention, by magnetically holding the same developer as used in the developing step on the surface of a developer-holding member by means of a magnet disposed within the developer-holding member, moving the surface of the developer-holding member in a direc-tion opposite to the moving direction of the surface of the photosenstive member to contact the two surfaces at reasonable relative speeds through the layer of the developer, and thus mechanically brushing the surface of the photosensitive member by the layer of the developer.

Abstract: ABSTRACT OF THE DISCLOSURE      Automatic card embossing apparatus includes a rotatable embossing wheel carrying about its periphery punch and die pairs for all characters available for embossing.  Each character position of the wheel defines an address and the wheel is controlled for rotation to a desired address for embossing the character there located.  Data identifying all embossable characters is processed to derive three control numbers for each character, the first control number identifying the corre-sponding wheel address for the corresponding punch and die pair, the second number identifying the horizontal position on the card where the character is to be embossed, and the third control number identifying the line number on the card.  The data is sorted into ascending order of wheel addresses.  In operation, a card is transported to a reference position relative to the embossing wheel and the embossing wheel is rotated to the address of the first control number.  The distance to move the card based on the second and third control numbers is computed and the card is transported to each successive position for that first character to be embossed.  The embossing wheel then is rotated to the next address in accordance with the next first control number and the embossing card transport functions performed.  Following embossing the card is returned to its reference position, then to an output stacker where it is deflected into "accept" or "reject" portions as a function of error checks performed during data processing and embossing.

Abstract: ELECTROMAGNET FLUID PUMP                         ABSTRACT         This invention relates generally to fluid pumps of the type which may be used, for example, to aerate water in an aquarium.  Prior art pumps have a flexible diaphragm which define one wall of an internal pumping chamber and which is reciprocated by a direct or indirect mechanical drive.  Direct drive diaphragm pumps are typically relative-ly complex and expensive in construction and indirect drive diaphragm pumps tend to be relatively noisy in operation and are subject to periodic failure.  The electromagnetic fluid pump of the present invention is of simple construction and has a minimum number of moving parts which are very quiet in operation and have long operating life and, if repairs are needed, are very simple and inexpensive to service.  Speci-fically, the pump of the invention comprises an electromag-net motor unit including an electromagnet for producing a reversing magnetic field to drive a fluid pump unit includ-ing a pump casing and a flexible diaphragm defining a fluid pumping chamber.  A permanent magnet is carried by the flexible diaphragm and to alternately repelled and attrac-ted by the magnetic field to displace the diaphragm to expand and contract the pumping chamber.
