Abstract: VARIABLE FORCE SHEET FEEDING MECHANISM                Abstract of the Disclosure A buckling type paper sheet feeding mechanism wherein the top sheet of a stack is separated from the underlying sheet by first driving the front sheet edge in a rearward direction against a rear restraint, causing the top sheet to buckle, and then reversing the direction of sheet drive, causing the top sheet to be fed in a forward direction over a front stack edge restraining or hold-down means. The top sheet is moved rearward by a variable force means which provides a progressively increasing buckling force, to thereby ensure reliable feed of paper of varying types, weights and humidity content, while at the same time minimizing the possibi-lity of double sheet feed.  A variable position rear restraint moves rearward, in synchronism with operation of the variable force means, to increase the column length of the top sheet as the buckling force increases.

Abstract: ABSTRACT OF THE DISCLOSURE      The proportion of nonfat dry milk which is needed to achieve a given quality standard of body, taste, and eye appeal when added to skim milk and lowfat milk products (including skim milk itself) is substantially reduced (for example by about 1/3) by adding an extra step of steam heating the preheated condensed milk to be powdered, while avoiding coagulation, this extra steam heating preferably following heat treatment previously conven-tional and preferably including steam superheating also in the earlier or skim milk phase.  The proteins are thus converted to a new form surprisingly effective as a modifier of skim milk food products, with little or no danger of such side effects as taste impairments which were hazards of the higher of previous heat treatments.

Abstract: ABSTRACT OF THE DISCLOSURE         In a color television receiving circuit, a color-demodulating subcarrier signal produced by an oscillator is applied through a first variable phase shifter and further through only a second variable phase shifter to a second color demodulator circuit.  The subcarrier signal, after passing through the first variable phase shifter, is applied to a color demodulator circuit provided particularly for hue error detection, When a received composite color television signal includes a vertical interval reference (VIR) signal, the detected output from the hue-error demodulator circuit is used to control the amount of phase shift of the first variable phase shifter, thereby automatically correcting the color hue.  On the contrary, when the received signal does not include the VIR signal, the amount of phase shift of the first variable phase shifter is constant.  The amount of phase shift of the second variable phase shifter can be changed by a common adjusting variable resistor irrespective of whether the VIR signal is present or not and hence the color hue can be preferentially adjusted.

Abstract: Abstract of the Disclosure Digital data in self-timing reference is free from error due to irregular data spacing because of variations in speed and/or direction of scan in manual or machine applications with a pulse modulation of retrospective nature. Initially reference data manifestations are established and thereafter digital data are established partly on the basis of preceding manifestations of the data.  In a binary data translating system, for example, a pair of reference pulses are spaced apart by a given interval.  A binary unit is thereafter manifested by a pulse following at the same or similar interval and a binary zero is manifested by a pulse following at a differing interval.  Each mani-festation of a binary number thereafter depends on the interval between pre-ceding pulses.  A principle advantage of retrospective pulse modulation lies in demodulation.  Large variations in the spacing and relatively larger variations in the scanning speed are accommodated readily.  Magnetic tape and like records can not only be addressed at conventional high speeds in searching and at conventional low speeds later used in reproducing but, also can be searched continuously as the change is made between those speeds.  Adaptive rate communications are particularly enhanced by the principle.  Optical scanning of bar codes is improved by differing the spacing of uniform width bars or with bars of differing widths and differing spacing.  These arrangements are applicable to railroad car and like object identifying, label data processing, human identification, card data processing, graphical display data probing systems and many other uses. Synchronous and asynchronous capability permits input to almost any digital data processing system.

Abstract: METHOD AND APPARATUS  FOR FORMING CRYPTS      ABSTRACT OF THE DISCLOSURE          A collapsible crypt form comprises an elongate rigid upper wall and two depending elongate rigid side walls joined at their adjacent margins by elongate rounded strips of resilient sheet material.  Actuating means are connected to reinforcing rails at the lower edges of the side walls to extend them away from each other to operating position and retract them toward each other to reduce the effective height and width of the form for release from a finished recess.  A back plate is held against the aft end of the body to prevent entry of flowable concrete and is disconnected from the body and removed from the recess after the body has been removed.   A plurality of forms are placed in side by side spaced relation on a concrete slab with their forward ends in alignment with the forward edge of the slab and form plates are secured to the forms, locking them together and preventing loss of concrete.  The concrete is poured and leveled to produce a tier of recesses with partition walls between them and a new slab above them.  The process is repeated until the desired number of tiers are completed.

Abstract: ABSTRACT OF THE DISCLOSURE   A communication system for repeating a data signal received on one input/output line onto one or more other input/output lines while in-hibiting the data signal repetition on the input/output line having input data being received thereon.  The first bit of the incoming data signal is detected to generate a control signal for a line selector latch.  The line selector latch latches in response to the control signal with the appropriate incoming line identification stored therein.  This stored line identification is used to control a multiplexer which selects the corresponding one of a plurality of input signal detectors connected to respective input/output lines to supply an input signal to a signal repeater.  The stored line identifica-tion also generates an inhibit signal to inhibit operation of a line output driver associated with the input/output line on which the incoming data was detected.  An output signal from the signal repeater and timing signals are applied to a signal shaping circuit to develop input signals for the line out-put drivers to repeat the data signal by all uninhibited line output drivers.
