Abstract: Analog Signal Verification Circuit Abstract of the Disclosure The present system employs a high speed digital signal processor which is programmed to generate pairs of digitized waveforms, each pair representing a pair of different frequencies in response to coded input signals.  Each pair of different digitized waveforms, when converted and combined into an analog signal, represents a "tone pair" as used in major telephone systems.  The tone pairs are transmitted through an anti-aliasing filter circuit and therefrom through amplification circuitry to a tone pair decoder of the type used in major telephone systems.  At the tone pair decoder the tone pair signals are reconverted into binary signals.  The binary signals from the tone pair decoder are transmitted to a data processor in the system under test, whereat they may or may not be further decoded.  Ultimately the binary signals are compared with the coded input signals originally sent.  In this way, the system which is designed to handle digital signals and which is designed to handle digital to analog conversions, is tested.  The test circuit employs components already present in the system, or readily adaptable from the major telephone systems equipment.

Abstract: "ELECTRONIC LIVESTOCK WATERING DEVICE"     ABSTRACT OF THE DISCLOSURE           Conventional  stock  watering  devices  include mechanical  water  level  controls,  floats  and  linkages within an immersion heater and usually bi-metallic strips are used to control temperatures.  All of these compon-ents are easily corroded particularly when highly miner-alized water  is often the only source.   The present device eliminates all moving parts with the exception of an electronically controlled solenoid valve for opening and closing the water intake line.  It is controlled by electronic sensors within an insulated stainless steel tank which includes a heat blanket bonded to the base thereof.  Furthermore it includes an automatic shut down capability if there is no water in the tank.  All of the controls are contained within an insulated casing which in turn may be maintained at a working temperature by means of a separate heater if desired.

Abstract: SPRING BIASED SPOOL TYPE VALVE CONTROLLER        FOR A PNEUMATIC DUAL DIAPHRAGM CONTROL SYSTEM                    ABSTRACT OF DISCLOSURE     The invention relates to a direct acting pneumatic control system for controlling a dual diaphragm, or double acting cylinder type automatic guiding system. The control device and system is used to selectively adjust the position of one end of a roll relative to the opposite end, in order to adjust the posi-tion of an endless web traveling over a series of rolls.        In order to adjust and control the guide roll position, it is necessary to alternately exhaust one diaphragm, and or cylinder end, while maintaining the flow of air to the opposite diaphragm or cylinder end.  This in effect shifts the roll in a lateral position effectively steering the web in the proper direction to effect the necessary web correction.        To activate and control the valve position, the control valve is equipped with a palm which follows the web and con-tinually monitors the web position and activates the control valve spool to modulate the "flow-exhaust" rates to bring the web to a corrected position with no over-run or "hunting" for posi-tion.  The palm and its associated rod must follow the web when the web is moving away from the palm.  It is necessary to have thrust within the valve to accomplish this function.  In this design, the thrust is accomplished through the application of a helical spring, totally enclosed within the valve body, and acting directly on the valve spool.

Abstract: AUTOMATIC RETARD ADJUSTMENT             MECHANISM FOR SHEET FEEDING          Abstract of the Disclosure A sheet feeding apparatus includes a retard mechanism to prevent the inadvertent feeding of doubled or overlapped sheets.  The retard mechanism includes a plurality of belts in an assembly positioned adjacent to a sheet feeding roller, and rotating in such a direction as to retard the sheets being fed.  The retard assembly is mounted on the free end of a lever arm pivotally secured adjacent to its other end to the base of the sheet feeding apparatus. The lever arm with the retard assembly mounted thereon is spring-urged toward the feed roller, but may be moved slightly away from said roller to accommodate the thickness of the sheet being fed between the feed roller and the retard assembly.  A dual spring arrangement contained in the lever arm permits the lever arm to move with relatively little force to accommodate passage of a single sheet, but to resist more vigorously any additional movement, such as would be required for the passage of double or overlapped sheets.  A one-way retaining device permits movement of the lever arm and retard assembly toward the feed rollers as the roller and belts wear, but prevents movement away from said roller except for the limited movement permitted to accommodate sheets during feeding.  The retaining device may be released to permit the lever arm and retard assembly to be swung away from the feed roller for replacement of the feed roller and retard belts when worn.

A stereo detector is coupled to the IF pick-up for detecting from the IF audio signals monophonic and stereophonic components that are transmitted with the composite television signals.  The detected components are decoded into left-channel and right-channel audio signals; and these left-channel and right-channel signals are adapted to drive sound transducers, such as loudspeakers.  Optionally, the left-channel and right-channel audio signals are amplified by gain-controlled amplifiers whose gains are a function of the output sound level of the television receiver.

Title: Multiple casting mould with top reservoir - has differential gradient in reservoir with molten metal discharge ports related to specified mould portions
IPC: B22D35/04
Filed: 1973-05-17
Abstract: Molten metal flows from a bottom-pour ladle through >=2 stoppered-outlets via runner-ccups into a filler-head in the top of the mould. The bottom of this head slopes so that the end with the narrowest depth is located above the smallest mould-cavities, i.e. with the shortest filling time, whereas the deepest part is over the largest cavities with the longest filling time. The head may consist of one basin or e.g. two channels connected by two grooves, the bottoms of which slope from the shallow channel down to the deep channel. The metal is poured in at the ends of each channel which contain a row of downgates leading to the small and large mould-cavities respectively. In the end phase of the pouring operation when the small cavities have been filled, the stopper over the shallow channel is closed and the stopper over the deep channel used to provide the precise amt. of molten metal required. In this way, larger amts. of metal can be fed at increased speeds into multiple-moulds contg. cavities of different size.
