Abstract: ABSTRACT OF THE DISCLOSURE                A teaching apparatus including a casing with two windows therein, and a plurality of buttons in front of one of the windows.  The buttons are aligned with answers, for example answers to mathematical questions, visible in such one window, and one question is visible in the other window.  If the button in front of the correct answer is pressed, the question disappears and the same or a different question appears in such other window.  If one of the buttons in front of the correct answer is pressed, nothing happens, i.e., the question remains in view.  The sets of questions and answers can be changed, because the questions and answers are both on tapes containing a large number of questions and answers.  The tape bearing the questions is mounted on spools in a transparent cylindrical cup, the tape extending around the inner periphery of the cup.  The cup is integral with a cam shaft rotatably mounted in the casing, the shaft including cams engageable, one at a time, by levers connected to the buttons to cause the shaft and cup to rotate.

Abstract: PROCESS FOR THE PRODUCTION                OF A PROTEIN PRODUCT                Abstract of the Disclosure A method of preparing a protein food product having an arrangement of helically aligned protein layers is disclosed wherein an aqueous slurry of a proteinaceous material is frozen by conveying said slurry through an extruder equipped to provide a freezing zone in order to form ice crystal layers in said slurry which mold the protein material of the slurry into striated layers arranged in the form of a helix.  The frozen extruded pro-duct is then heat set at a temperature sufficiently high to allow the protein layers to heat set and melt the ice crystal layers to form a protein food product.  The resultant product has an improved degree of toughness because of "cross structuring" of the protein layers which is an inherent effect of the helix arrangement of the protein layers in the product.

Abstract: ABSTRACT OF THE DISCLOSURE            Electrothermal fluidized bed furnace useful particu-larly for chlorination of oxide of zirconium and the like.  The graphite reactor tube is longitudinally divided into a plurality of separate sectors by the corresponding number of longitudinal slits which are filled with insulating and refractory material.          Said reactor tube sectors are physically and electrically united at one end of the tube so that one or more pairs of opposite sectors are electroresistively heated while the intervening opposite sectors are left electrothermally unactived for prevent-ing short circuit to be otherwise eventually caused due to carbon fed together with said oxide.  Owing to such electrothermal system the furnace wall can be fluid-tightly sealed with use of metallic material for preventing harmful chlorine gas from leaking.  Owing to said construction, the life of the graphite tube can be prolonged.

Abstract: ABSTRACT OF THE DISCLOSURE         A sintered pulley hub construction for mounting on a bottom wall of a sheet metal pulley cup.  A pair of tubular mem-bers is pressure formed in a green compact state from a metal powder mixture.  One of the members has a cylindrical body which terminates at one end in an outwardly extending annular flange which forms a hub pulling flange.  The other member has an inter-ior annular cavity formed in one end and a radially outwardly ex-tending annular flange forced on the other end.  The cylindrical body of the one member is telescopically received within the annu-lar cavity of the other member.  The members are joined by sin-tering to form an integral homogeneous body.  The outer surface of the other member has a cylindrical portion extending axially between the radial end flange and an annular shoulder for receiv-ing an axially extending flange of a pulley cup, with the shoulder providing a zone for welding the pulley cup to the hub.  The method of forming the improved hub includes the steps of separ-ately pressure-forming each of the tubular members in a green compact state in a pair of molds.  Then a cylindrical end portion formed on one of the tubular members is telescopically mounted within an annular interior cavity formed in one end of the other tubular member.  The joined members then are sintered in a fur-nace and the green compacted members cohere to each other and form an integral homogeneous member.

Abstract: MEASURING-WHILE DRILLING SYSTEM AND METHOD  HAVING ENCODER WITH FEEDBACK COMPENSATION                ABSTRACT OF THE DISCLOSURE      A measuring-while-drilling system having a downhole, motor-driven acoustic signal generator includes a motor speed control circuit featuring feedback compensation which accounts for varying loading conditions on the motor.  The acoustic signal generator is motor driven at speeds for im-parting to well fluid an acoustic signal having phase states representative of data derived from measured downhole con-ditions.  The motor control circuit includes circuitry which forms a phase locked loop for driving the motor at a refer-ence phase and at a substantially constant carrier frequency producing speed in the absence of data of one logic state and also includes circuitry for temporarily changing the speed of the motor, according to a pre-programmed function, to effect, a predetermined amount of phase change in the carrier signal upon data of the predetermined logic state.          Upon occurrence of the data, the motor control circuit takes control away from the phase locked loop and changes the speed of the motor from the carrier frequency producing speed for accumulating a prescribed portion of the pre-determined amount of phase change.  To accumulate the remainder of the predetermined amount, it then returns the speed of the motor to the carrier frequency producing speed at which time it returns control of the motor to the phase locked loop.  During operation feedback from the motor is provided to update the value of the prescribed amount ac-cording to loading conditions on the motor.  This minimizes the time period required for the phase locked loop circuit to precisely establish the predetermined amount of phase change in the acoustic signal at the carrier frequency.

Abstract: Application for Patent of John A.C. Bingham  and Ronald K. Maxwell for DUPLEX DATA TRANSMISSION MODEM UTILIZING AN INJECTING TONE FOR SHIFTING POWER WITHIN THE TRANSMIT SPECTRUM                                 ABSTRACT A full duplex communication system including a pair of full duplex modems.  Each modem has both a call originate mode of operation and a call answer mode of operation.  In the call originate mode outgoing data is transmitted by modulation of a carrier frequency F2 and incoming data is received by demodu-lation of a data modulating carrier of frequency F1.  When in the answer mode of operation, the data is received on frequency F2 and transmitted on frequency F1.  Means are provided for injecting a carrier frequency F6 in the outgoing data transmission path.  The frequency F6 is near the midpoint between F1 and F2. The amplitude is such that the distribution of power within the transmission band is balanced so that the power in the frequency band set aside for single frequency signaling systems does not exceed the power in the remainder of the transmission band. This prevents the false operation of signal frequency systems triggered by the transmission of certain bit patterns, which could result in improper billing, intermittent transmission interruptions, insertion of a band elimination filter in the transmission path or the complete disconnection of a call.
