Abstract: Abstract of the Diclosure Locking device for a safety belt having a belt lock into which a plug-in tongue can be inserted and be locked by at least one locking latch.  The locking latch can be moved by a manual pressure element transversely to the plug-in guide from the locked position into the open position.  A spring-activated sliding ejector is disposed within the plug-in guide.  A stop which can be moved into the slide path of the ejector acts in conjunction with the pressure element. The stop blocks the ejector in a position a short distance from contact with the locked plug-in tongue.  The ejector is released by moving the pressure element into the opening position.

Abstract: Abstract of the Disclosure A feed mechanism comprising a rotor and an endless flexible belt carried by the rotor.  The rotor comprises a pair of cylindrical guide members arranged coaxially one within the other, the guide members being mounted for rotation in unison about a common axis.  Each of the guide members provides a helical groove defining a respective feed channel, the grooves being of the same pitch and opposite hand, and the belt is constrained by the guide members to extend helically along the feed channels in sliding engagement with the guide members.  The belt protrudes from one of the feed channels to engage a restraining surface which restrains the belt against rotation so that, in response to rotation of the rotor, the belt is continuously advanced along one of the feed channels and returned along the other, thereby providing a continuously advancing non-rotary bearing surface which bears against the restraining surface.

Title: Automatic swimming pool cleaner
Inventor: HENKIN MELVYN L
IPC: E04H4/16
Filed: 1981-11-05
Granted: 1983-05-24
Abstract: ABSTRACT An automatic swimming pool cleaner comprised of a car adapted to travel underwater along a random path on the pool vessel surface for dislodg-ing debris therefrom.  The car wheels are driven by a water powered turbine to propel the car in a forward direction, along the vessel surface.  In order to prevent the car from being driven into a position, as for example against a vertical wall, from which it cannot emerge, a wheel geometry is employed which, upon contact, develops a horizontal force component parallel to the vertical wall, to thus enable the car to spin off.  Alternatively, or in combination, a water flow produced reaction force can produce a torque to turn the car with respect to the engaged wheel to enable the car to spin off. The car is designed with a low center of gravity and a relatively buoyant top portion so as to produce a torque which maintains the car correct side up when on the pool bottom.  Means are provided on the car for producing a water flow having a force component perpendicular to the vessel surface to provide good traction between the car wheels and the vessel surface.  Further a water flow produced suction is created adjacent to the vessel surface for collecting debris into a basket carried by the car.  In addition, one or more hoses is pulled by the car and whipped by water flow to sweep dirt from the vessel surface.

Abstract: ABSTRACT OF THE DISCLOSURE         A high security subscription television system which includes the feature of dynamic scrambling and descrambling of cable-connected television signals in response to real-time coded control signals.  The system also has the ability to precisely tune the frequency con-verter unit at the subscriber's site, in response to real time coded control signals provided by a computer at the central transmitting station.  Various methods of scrambling and descrambling are described which use manipulation of the video signals at the baseband video level, and also at the RF level.  Alternate embodiments of the descramblers include a secondary source for the reference carrier signal required for proper descrambler operation.  In an ultra-stable embodiment of a subscriber's control terminal, a single crystal controlled master oscillator is used to control the frequency conversion unit, to provide a clean reference carrier signal for the descrambler unit, and to tune the control signal receiver, thereby removing the need for frequent fine tuning control adjustments, and further allowing simplified system design and fabrication.

Abstract: Abstract Process for the preparation of alcohol-free drinks with a yeast aroma To prepare alcohol-free drinks with a yeast aroma, such as alcohol-free beer, an aqueous starting liquid containing nutrients and/or flavour substances is used. The starting liquid can be prepared by mixing a nutrient and/or flavour substance concentrate with water.     A yeast is removed from a fermentation process and is freed from the fermented liquid.     The starting liquid and the yeast are brought into contact with one another, and in particular at such low temperatures that virtually no alcoholic fermentation occurs.     The starting liquid and the yeast are left in contact with one another until the aroma substances of the yeast have diffused from the cell into the liquid and the yeast has exerted its reducing effect.

Abstract: (Case No. 7105) ABSTRACT OF THE DISCLOSURE    The speed proportional frequency signal from the speed generator being checked is amplified and applied to a high-pass filter-rectifier with a low frequency limit corresponding to a predetermined minimum train speed.  Polarity of the rec-tified output is opposite to the DC operating energy so that, with four-terminal load resistor and smoothing capacitor, the filter-rectifier operation is vital.  The rectified signal activates an oscillator level detector when its level exceeds the breakdown of a Zener diode control device selected to cor-respond to minimum speed output.  The level detector is coupled by a stepdown transformer to a differential amplifier biased by a signal supplied from an associated zero speed detector.          The bias signal has sufficient level to enable the differential amplifier to produce an output in response to the level detec-tor input only when the train speed is greater than zero.  This output represents proper operation of the axle generator and is coupled to enable the train speed governor to respond to other train control signals.  When the train is stopped, the differential amplifier is biased below operating level.  How-ever, a supplemental bypass signal present only when train brakes are set is coupled through the differential amplifier output to enable the speed governor during station stops.

Abstract: FOLD-AWAY BED ASSEMBLY     ABSTRACT OF THE DISCLOSURE      Conventionally, fold-away beds include lift mechanisms either pneumatic or coil springs reacting between the rear of the bed frame and the base of the vertical support frame-work in order to act as counterbalances for raising and lower-ing the bed.  This places considerable stress and strain upon the vertical frame which has to be anchored firmly to the wall or supporting surface and these anchors often become loose due to the strains imposed thereon.  The present in-vention includes a relatively lightweight frame and bed unit pivoted by the rear thereof to adjacent the base of the frame.        A pair of lift arms extend upwardly and rearwardly from the bed unit just forwardly of the pivot points and springs ex-tend from the lift arms upwardly and rearwardly to be secu-red to the vertical frame sides intermediate the ends there-of.  The leverage action provided is such that the vertical frame is easily secured to the wall or supporting structure as very little strain is placed thereon as the bed is raised and lowered.  Furthermore, the lifting mechanism is simple and requires relatively lightweight components compared to conventional fold-away beds.

Abstract: Abstract A controller for controlling fluid flow from a source to a motor, such as the steering motor of a motor vehicle. The controller includes a metering section and a control valve section comprising a stacked assembly of plate valve members which control flow and, along with the metering section, define the outer periphery of the controller, and minimize the need for complex cast housing members.  The controller is compact and yet is constructed to respond to an input signal from an input shaft to direct needed flow from the source to the primary steering motor, and excess flow to an auxiliary motor.  The controller is also characterized by a unique spring centering mechanism which applies a spring centering force to the assembly of plate valve members.  Additionally, the controller is characterized by a special seal arrangement for resisting leakage of high pressure fluid about the input shaft, and by structure for forming pressure dams to resisting leakage of metered fluid.
