Abstract: RCA 74,039 ABSTRACT OF THE DISCLOSURE         A side pincushion corrected deflection circuit for a television receiver includes a deflection winding, a trace capacitor and a first switch for generating scanning current in the deflection winding.  A modulator circuit includes a modulator inductor, a modulator capacitance and a second switch for generating a sawtooth modulator current in the inductor.  The trace and modulator capacitors are charged from a voltage source through a flyback transformer winding. Reflected load currents from other television receiver circuits also flow in the flyback transformer winding.  A transistor stage in the modulator circuit shunts current away from the modulator capacitor to control the modulator and trace capacitor voltages.  A vertical rate bias voltage is applied to the transistor stage and varies the shunt current at the vertical rate to provide side pincushion correction.  The transistor stage is operated in an open loop manner with no voltage feedback of the modulator capacitor voltage.  An additional bias voltage, representative of the load current flowing in the flyback transformer, is applied to the transistor stage in order to reduce undesirable load current modulation of the side pincushion correction.

Abstract: Abstract of the Disclosure A sofa bed mechanism consisting of three sections, namely, a rear section, an intermediate section, and a front section, that are foldable between collapsed sofa positions in which the sections are in substantially horizontal vertically stacked positions and bed positions in which the sections extend in substantially horizontal alignment.  A frame supports the sections, the frame being of minimum width by which is meant the frame is of a shallow dimension in a direction front to rear of the sofa. The sections are stacked on top of the frame in their sofa positions so that the frame and the sections present a compact substantially rectangular profile when viewed from the end of the frame, thereby allowing substantial flexi-bility in the design of the sofa in which the mechanism is mounted.  The end sections are connected by hinge assemblies located entirely on the sides of the assemblies to avoid the necessity for any cross tubes that might interfere with sleeper comfort in the bed position of the mechanism.

Abstract: ABSTRACT      A power assisted vehicle steering system has a pressure biased piston and cylinder (1) actuation of which effects in the power assistance.   The piston (2) has axially opposed faces (5, 7) with different effective pressurised areas of which the face (5) with the smaller area communicates with a first chamber (6) and the face (7) with the larger effective area communicates with a second chamber (8).   A valve (10) which is axially adjustable (but may be rotary) in response to a steering manoeuvre controls flow of pressure fluid from the pump (9) to the piston and cylinder (1) for providing power assistance.   The valve (10) derives fluid pressure from the pump (9) through a restrictor (26) (which may be adjustable) and has a neutral condition in which the first and second chambers (6, 8) and the pump output communicate with the reservoir (23) by way of control ports (18, 19, 20) in the valve, the second chamber (8) communicates with the pump by way of the restrictor (26) and the control port (19) and the first chamber (6) communicates with the pump upstream of the restrictor (26) and the control port (19).   The restrictor (26) is arranged so that with the valve (10) in its neutral condition the fluid pressure in the second chamber (8) provides an axial force on the piston face (7) which balances the opposing axial force on the smaller piston face (5).

Abstract: ABSTRACT OF THE DISCLOSURE         A device for feeding purging and degraphitizing air into pipes for rich gas leading to the heating walls of coke ovens.  A first cross-section opening is connected to the pipe for rich gas and can be locked with a first gate and is adapted to initially release only a relatively small aperture cross-section for passing purging air.  A second cross-section opening is connected to the pipe for rich gas and can be locked with a second gate and is adapted to release successively with a time delay after the first cross-section opening a relatively larger cross-section for passing degraphitizing air.  An exchangeable screen can be placed in the opening for the first cross-section opening.         The device prevents deflagrations caused by feeding inaccurate amounts of purging air into the pipe for rich gas.

Abstract: ABSTRACT OF THE DISCLOSURE           A method for correcting a measuring signal which has been generated by an apparatus measuring in contact-free fashion.          The apparatus scans a surface to be measured with a light beam, measures the light reflected by the surface by means of an opto-electric detector installation, and generates the measuring signal in dependence upon one or more electrical signals emitted by the detector.  In the case of the above-described apparatus, distor-tions of the electrical signal emitted by the detector, which distortions occur for example through non-uniform scattering ability of the surface to be measured, can result.  These distor-tions lead to measurement errors.  Such measurement errors are corrected in the simplest manner possible.  For this purpose, the measuring signal is corrected in dependence upon a distortion of an electrical signal.

Abstract: VEHICLE HAVING IMPROVED COUPLING SYSTEM      AND SYSTEM FOR ABSORPTION OF      SHOCK ON COUPLING     Inventor:  Eugene B. White, Jr.     ABSTRACT OF THE DISCLOSURE           A self-propelled vehicle for moving railroad cars and the like.  The vehicle may have weight transfer means for increasing its traction by taking weight from a railroad car to one that is coupled.  The vehicle defines a first chassis having wheels carried thereby.  In accor-dance with this invention, a second chassis is carried by the first chassis, with the second chassis carrying means for coupling the vehicle to a railroad car or the like, the second chassis being vertically movable relative to the first chassis.  Lift cylinders may be positioned between the first and second chassis to control the vertical posi-tion of the second chassis for improved coupling character-istics.  Also, the second chassis may be horizontally mov-able along the longitudinal axis of the vehicle, with re-silient stop means being present for limiting the horizontal motion of the second chassis in a shock-reducing manner.          Accordingly, shock encountered by the transmission means of the vehicle, while coupling with railroad cars and the like, is reduced.

Abstract: MAINTENANCE OF PROTEIN IN QUALITY IN FOODS CONTAINING REDUCING SUGAR                           ABSTRACT  .        The object of the invention is to provide an improved proteinaceous food product and a process for preparing it.      The current commercial production of protein-aceous food products often employs the use of re-ducing sugars under conditions which result in the loss of protein quality due to the Maillard re-action.  The present invention improves upon these food products and provides a process for stabilizing the protein quality of them.      According to the invention, an effective amount of a non-essential free amino acid is incorporated into the food composition to save the protein qual-ity from degradation.  A preferred group of products are intermediate moisture products, particularly pet foods,  which contain reducing sugars such as corn syrup and high fructose corn syrup to serve as water binders.   The  preferred non-essential  amino acid additive  according  to  the  present  invention  is glycine and its soluble salts.
