Abstract: ABSTRACT OF THE DISCLOSURE        A wall-mounted receptacle for smoking material such as cigarettes includes a cylindrical inner container and a cylindrical sleeve which telescopically fits over, and can rotate on, the container,  The container has diametrically opposed upper and lower side wall openings while the sleeve has a single side wall opening.  In normal use the sleeve opening is in registry with the upper container opening and smoking material may be placed into the container through the registered upper openings.  When the receptacle is to be emptied the sleeve is rotated until its opening registers with the lower opening of the container whereby refuse may be removed through the registered lower openings.  The receptacle is inexpensive, decorative, and is especially useful in "no-smoking" areas as it prevents the retrieval of the smoking material after deposit therein.

Abstract: ABSTRACT         A system and method for diagnosing and treating undesired internal conditions and structures, such as occluded vessels of aberrant histological regions.          Diagnosis is effected by means of doppler analysis of laser light directed to the effected site from an inserted laser-containing unit, and treatment is accomplished by the same unit through direction of laser emissions of controlled characteristics toward the target site, thereby accomplishing departicalization, disintegration, and elimination through normal bodily processes of the undesired structure.  Coherent radiation of a determinate size, wave amplitude, and electronic composition is precisely directed to given loci of operation for non-ivasive analysis and treatment of aberrant sites.  The invention embodies a novel unitary device with an assemblage of automated diaphragms, beam splitters, electronic choppers, an auto-mated dye cell subsystem, and a focusing turret equipped with rotating lens elements and a piezoelectric element.          The system directs, focuses, and alters the electronic characteristics of one or more laser emissive sources onto a fiber optics array.  The assemblage of subsystems includes an aspiration infusion pump, aspiration conduits, infusion conduits, and emission fiber optics and return self-focusing fiber optics elements within an automated hydraulic hypodermic delivery system.

Abstract: DIFFERENTIAL TRANSMISSION MECHANISM    FOR A CONSTANT SPEED DRIVE                             Abstract A differential transmission mechanism using an output differential for a constant speed drive has de-sirable characteristics including full utilization of the torque capabilities of the hydraulic trim device asso-ciated with the output differential; however, there is a limitation on the utilizaton of the speed capability of the hydraulic components of the trim device at the low end of the input speed range.          The disclosed differential transmission mechan-ism utilizing an output differential has a hydraulic trim device with a first hydraulic displacement unit having a normally fixed, approximately maximum displacement con-nected to an element of the output differential and a second hydraulic displacement unit which is of variable displacement connected to a variable speed input shaft. Additional components of the output differential are connected to the input shaft and to an output shaft con-nectable to a load.  A sensing device senses the speed of the output shaft to control the displacement of the variable displacement hydraulic displacement unit to control the displacement thereof to achieve a constant output speed by varying the speed of the normally fixed displacement unit as required.  Additionally, a sensor senses the speed of the input shaft and, when the speed of the input shaft is below a predetermined value, con-trols the displacement of the normally fixed displace-ment unit to reduce the displacement thereof to ef-fectively make the latter displacement unit a smaller unit which will therefore operate at a faster speed to extend the range of the constant speed drive at the low end of the input speed range.

Abstract: Abstract A temperature controlling method and appara-tus are provided using digital control and information stored in memory.  The apparatus includes a number of on/off valves.  A first set of valves is used to receive cold water and a second set of valves is used to receive hot water.  The opening and closing of the valves is controlled by an electronic controller.  Each of the valves is able to receive water from one of a plurality of orifices. In the preferred arrangement, a first set of orifices supplies cold water to the first set of valves and a second set of orifice supplies hot water to the second set of valves.  The orifices of the second set are greater in size than are the corresponding orifices of the first set. The water from the valves and the orifices is combined in a common flow line.  The temperature of the water in the common flow line is monitored and a signal indicative of the actual water temperature is outputted to the controller.  The controller, using the stored information, acts to open and close the valves until a water mixture is achieved in which the actual, sensed temperature corresponds to a desired water temperature selected by the user of the apparatus. In reaching the desired water temperature, the con-troller is able to cause the opening of numerous combinations of valves.

Abstract: CHIP CARRIER EXTRACTION TOOL    ABSTRACT            A tool for extracting a microelectronic chip carrier from a receptacle to which it is connected. It includes left and right arms, each having coextensive members in the form of a substantially rigid tong and a flexible leg. Both arms are pivotally mounted at a common axis for relative movement. A distant end of each tong terminates at a chip carrier engaging hook and is slidably received in a channel formed in a tong support at a far end of the leg.  Each leg has a bearing surface at its extreme end and a hinge member intermediate its ends and is bowed outwardly of its associated tong. With the bearing surface engaged on the receptacle, the arms are opened sufficiently wide that the hooks which are extended from the bearing surface when the tool assumes its relaxed condition, straddle the chip carrier. As the arms are squeezed together, lateral movement of the flexible leg members toward their associated tong members is effective to move the hooks, in a continuing sequence, first laterally toward and into engagement with the chip carrier, then longitudinally in a direction away from the receptacle until the chip carrier is dislodged from the receptacle.

Abstract: ABSTRACT OF THE INVENTION         A data processing system which includes a floating point computation unit (FPU) which interfaces with a central processing unit (CPU) in which the CPU supplies a dispatch control signal to inform the FPU that it is about to execute a floating point macroinstruction and supplies a dispatch address which includes the starting address of the floating point microinstructions therefor during the same operating cycle that the dispatch control signal is supplied.  A buffer memory is provided in the FPU to store the starting address of one decoded macroinstruction while a sequence of microinstructions for a previously decoded macroinstruction is being executed by the FPU.  When the buffer already has a starting address resident in its buffer the FPU supplies a control signal to prevent the CPU from supplying a further dispatch address until the buffer is empty.  Other control signals for synchronizing the CPU and FPU operations and data transfers are also provided.
