Abstract: ABSTRACT OF THE DISCLOSURE A video display system operates at a plurality of horizontal scanning rates.  A voltage source produces different voltage levels, one of which is selected in response to the horizontal rate selected.  A horizontal deflection circuit produces retrace pulses having amplitudes dependent on the scanning rate.  A high voltage transformer has a primary winding with a number of taps and a secondary winding;  The voltage source is connected to one of the taps in response to the horizontal deflection rate selected, so that the high voltage level developed across the transformer secondary winding remains substantially constant independent of changes in retrace pulse amplitude.

Abstract: ABSTRACT         The dual mode gas sampler and pneumatic flow control system of the present invention includes a flow control valve hav-ing a manually adjustable flow restricting orifice, a two position mode select valve, a flow controller and a vacuum pump for drawing gas from the atmosphere through a load representing either a single test article with flow being held constant or multiple test articles with pressure held constant.  In one position of the mode select switch the flow controller maintains mass flow through the load constant by regulating a supplemental flow of gas from the discharge side of the pump to the suction side of the pump in response to the pressure differential across the flow restricting orifice.  In the other position of the dual mode switch the flow controller regulates the supplementary flow of gas from the dis-charge side to the suction side of the pump in response to the pressure differential across the pump with the flow control valve bypassed.

Wood Abstract A microprocessor-based frequency shift keying (FSK) data communications module.  The microprocessor selectively modulates and demodulates data directly in terms of a square wave pulse train in which a first frequency is used to convey a binary "1" and a second frequency to convey a binary "O".  An input and an output port on the microprocessor are selectively coupled to a transmission line through a transformer, by means of electronic switches.  Also included are a bandpass  filter for shaping the square waves into sine waves and for filtering noise, and means including a notch filter for generating a carrier detect signal input to the microprocessor, when incoming data is detected on the transmission line.  Many of the components in the module are used for both transmitting and receiving data.

Abstract: ABSTRACT OF THE DISCLOSURE    The dimensions of a product passing through the finishing block of a roll rolling mill are measured. Where the dimensions of the product exiting the last finishing stand are out-of-tolerance, a calculation is made to determine the extent to which the roll parting of the work rolls of one of the two last finishing stands must be adjusted to bring the product into tolerance.  Based on the calculated adjustment, progressively smaller adjustments are made to the roll partings of the work rolls of the upstream finishing stands to distribute the work which must be performed on the product to bring the product into tolerance.

Abstract: ABSTRACT OF THE DISCLOSURE    A  flexible membraneous weir is disclosed.    When air  once filled  in  an air type flexible membrane weir is  discharged  in order to cause it to collapse, its membraneous wall is deformed in a  V-shape  at one portion in the river width  direction,  and  a stream concentrates into this portion.    However,  the  portion where   the   V-deformation  will  be  formed  is  not   certain.          Therefore,  it  is  required to reinforce the whole area  of  the river-bed and the river wall  at the down stream side.    In view of  the foregoing,  means is provided for starting  V-deformation onto  a  bag-shaped member  as a main body  of  the  weir  in  a predetermined  portion  at a time when the bag-shaped  member  is collapse  from its erected state.    With this  arrangement,  the stream can  be concentrated on the predetermined  portion  only.          Therefore  reinforcement is required only for a river-bed portion corresponding to this portion.

The full closure catcher is reliably actuated to assume a closed configuration without dependence upon gravity or an interference diametrical fit with the core by use of a cam ring which  is  longitudinally displaced  downwardly within  the core barrel by a preloaded compression spring.  The full closure core catcher  is  comprised  of  a  plurality  of  flapper  valves circumferentially disposed  outside  of  the  inner  tube  and concealed by the inner tube or a terminal extension of the inner tube.  Disposed above the plurality of flapper valves, and also circumferentially disposed outside of and concentric with the inner tube is a cam ring.   Similarly circumferentially disposed outside of and concentric with the inner tube is a preloaded coil compression spring bearing against the cam ring.  The cam ring in turn is in sliding contact with a rear surface of each one of the plurality  of  flapper  valves.    When  the  inner  tube is longitudinally displaced with respect to the flapper valves to uncover the flapper valves, the flapper valves are then rotated inwardly within the inner barrel of the coring tool by virtue of the downward longitudinal drive of the cam ring as powered by the preloaded compression spring.

Abstract: Abstract Title: Microwave Ovens and Methods of Cooking Food A microwave oven has a magnetron for producing microwave power and a resistance heating element over which air is forced by a fan to produce a forced flow of hot air through the oven cavity. A thermistor in the hot air flow senses the temperature of the hot air. Microwave power and hot air are produced simultaneously until the sensed hot air temperature reaches a predetermined threshold temperature (Tl). For baked food items this represents the end of the cooking process, but for meat items there is a final cooking stage during which no hot air is forced through the cavity, the level of microwave power being doubled during the final stage. The end of the final stage occurs when the sensed temperature drops to a predetermined threshold (TS) . The absence of forced hot air during the final stage makes the detection of the predetermined threshold temperature (TS) easier, because the slope of the hot air temperature/time curve is steeper than would be the case if hot air were produced to the end of the cooking process.
