Abstract: POWER TRANSMISSION                 Abstract of the Disclosure A balanced rotary sliding vane pump has a flexible cheek plate slightly spaced from the rotor and vanes.  A hydrostatic pressure pad exposed to outlet pressure urges the cheek plate to deflect toward the rotor and is fully effective at low speeds.  A pressure force opposing this deflection at higher speeds is pro-duced by restricting the outlet for fluid discharged by the inwardly moving vanes, thus augmenting the pressure field applied in the clearance space between the rotor and the cheek plate.  This speed responsive change in the cheek plate deflection provides for a high volumetric efficiency at slow speeds and also reduces the possibility of cheek plate wear and seizure at higher speeds when volumetric efficiency is less important.     i.

Abstract: ABSTRACT           An equapoised lamp comprising a lamp head mounted upon an arm assembly which is counterbalanced by springs en-closed within square tubes which are components of the arm assembly.  The arm assembly has a lower pair of parallel arms which are pivoted at their lower ends to a swivel bracket which turns about a vertical axis in a fixed bracket.  Each of those arms is pivoted at its upper end to a floating bracket which has pivoted to it a similar upper pair of parallel arms.  A lamp assembly is mounted upon the other end of the upper pair of arms by a univeral joint assembly.  The arms are tubular, and each pair forms a parallelogram by virtue of the pivotal connections with the respective brackets.  A coil spring is enclosed within one of each pair of tubes which exerts a coun-terbalancing effect upon its pair of arms.  A nylon shoe is mounted upon the free end of each spring and enclosed within the tube. The shoe transmits the counterbalancing force from the spring to the adjacent bracket.

Abstract: ABSTRACT OF THE DISCLOSURE This invention relates to the field of bucking devices for securing two objects together, and more particularly to the field of buckles having a male member and a female member and being designed to allow quick release.  Quick disconnect buckles are utilized in a variety of equipment.  Such buckles have usually included a male member which is insertable into a female member and one of the members has a flexible part which engages a rigid part of the other member.  The buckle is released by applying pressure to the flexible part to disengage the members.  With such a construction, it is possible to accidentally release the buckle.  The buckle of the present invention utilizes a male member having a rigid portion and a female member having a flexible portion for locking and a separate flexible portion of the male member for unlocking. During the locking action, the rigid male portion id inserted over the flexible female portion until the rigid part becomes engaged in a notch in the inside edge of the flexible female part.  To release the members, the flexible portion of the male member is forced against the flexible portion of the female member and causes it to move out of engagement with the rigid part of the male member.  The flexible part of the male member overlies the flexible part of the female member to prevent accidental release.

Abstract: INDUCTIVELY COUPLED KEYABLE CONTROL CIRCUIT AND KEYING    CIRCUIT THEREFORE USING HYBRID DETECTION MEANS     ABSTRACT OF THE DISCLOSURE       A keyable control circuit sequentially connects a widely swept fm rf signal to sensing coils at a plurality of detection locations.  While rf energy is fed to one of the sensing coils, all other sensing coils are gated off.  A resonant detector generates a first signal when an external keying circuit containing a tuned circuit, resonant at a correct first frequency, is inductively coupled to one of the sensing coils.  A time-gated envelope detector generates a second signal when the external keying circuit contains a second tuned cir-cuit resonant at a correct second frequency.   When the first and second signals are simul-taneously present, gating circuits generate a control output signal which may be used to unlock a door or perform other functions access to which is restricted to those pos-sessing keys.

Abstract: RESIST DEVELOPMENT CONTROL SYSTEM Abstract of the Disclosure In the process of developing exposed photoresist on a substrate, the endpoint in developing away all of the exposed positive photoresist or any other positive resist is detected by exposing a wafer with a predetermined pattern including an optical grating or other special pattern formed in the photoresist upon a test area.  In a system employing this concept, a beam is diffracted by the optics of the grating only at a first angle until the resist forming the grating is removed by development.  Then a sensor is activated when an angle of reflection is unblocked when the grating dis-appears.  The system is then turned off to stop development by the sensor in an automatic system or, by the operator in a manual system.  A double exposure technique is employed to produce the grating or other special pattern.

Abstract: ABSTRACT     System and method utilizing the temporal separation and amplitude differences of signals having high and low frequency components for transmitting the signals in a bandwidth corresponding  to one/half of the frequency range present in the signals.  One of the components is continuously translated to the frequency range of the second component with no switching of the first component, and the translated first component is combined with the untranslated second component with no switching of either components to provide an output signal consisting of the translated first component and the untranslated second component.  The levels of the components are adjusted in such manner that the components have different energy levels in the output signal. At a receiving station, the components in the output signal are separated, and the first component is restored to its original frequency range by combining the output signal with a signal of predetermined frequency when the output signal is at the level of the first component.  The restored first component is then combined with the second component to reconstruct the original signal.

Abstract: Abstract of Disclosure A table has a mechanically driven draw bar squeegee mounted thereon to spread ink and other substances in a uniform manner.  There is an interchangeable plurality of such squeegees which may be sequentially placed in said table to enable successive layers of different types of materials to be spread, in sequence, over the surface of a paper. This suc-cession of materials includes an isolation layer between suc-cessive colors of ink, whereby a mistake on work in progress does not necessarily lead to a final destruction of all pre-viously done work.  A feature of the invention is that the pigmented surface of dried ink is not seen through the tint of other material, such as photoresist,  for example.  Also, a releasable layer may be provided among the successive layers so that a hand proof copy may be transferred, as a decalcomania.
