Abstract: ABSTRACT:             A television transmitter comprises a video pro-cessing circuit, an amplitude modulator, a vestigial side-band filter, an R.F. amplifying stage and a klystron amplifier which feeds an antenna.  The klystron is provided with a grid electrode to which a video signal is  applied to density modulate the beam current.  The video signal applied to the grid electrode is derived from the output of the video processing circuit and fed via a low pass filter and a d.c. isolating circuit to an amplifier which provides a signal of the desired amplitude at the grid electrode. The filter is arranged to restrict the bandwidth of the video signal applied to the grid electrode to less than that of the vestigial sideband in order to reduce the possibility of re-inserting the higher frequencies into the vestigial sideband.  The d.c. isolating circuit isolates the video signal source from the cathode and grid potentials of the klystron which are typically  between 10 and 30 K volts.

Abstract: A B S T R A C T        A method of manufacturing boat parts submerged when in use comprises producing a metallic skeleton structure shaped for easiest production by conventional metal-forming methods, and covering this structure in a mold with an adhering layer or coating of a thermoplastic resin or a rubber-based vulcaniz-able substance. The inner walls of the mold have high finish and the desired streamlined outer shape of the finished pro-duct, such as a lower unit of a propulsion system, or a pro-peller and the like. The coacting functionally neutralizes the technologically conditioned and generally not streamlined shapes of the skeleton structure and provides a protection of the skeleton structure against electroerosive corrosion.

Abstract: ABSTRACT OF THE DISCLOSURE      A slider for a slide fastener comprises a slider body including a pair of upper and lower wings defining therebetween a Y-shaped guide channel, the lower wing having on its interior surface a ridge extending longitudinally of the guide channel for being locatable between a pair of stringer tapes of the slide fas-tener to slidably engage fastener elements of the slide fastener.          The lower wing also has in the interior surface a pair of furrows disposed one on each side of the ridge and extending parallel thereto for allowing fastener-element-supporting edge portions of the tapes to be displaced into the furrows respectively.  The furrows thus reduce frictional resistance between the stringers and the interior surfaces of the slider body.  With such slider it is possible to correct a longitudinal divergence in interengage-ment between the opposed stringers without breakage or other damage of fastener-element-holding threads. Thus, the invention facilitates the correction of longitudinal misalignment of slide fastener stringers on assembly of a slide fastener.

Abstract: APPARATUS FOR PROVIDING INTERCHANGEABLE KEYBOARD FUNCTIONS     ABSTRACT OF THE DISCLOSURE      An electronic weighing scale system capable of performing a plurality of functions.  Predetermined subsets of the functions can be accessed from the system keyboard.          The subset of functions which a particular keyboard can access is easily changed by replacing a non-volatile memory integrated circuit chip which may be the same one that contains postal rate information.  Memory locations within the chip are segregated into two complementary arrays, one containing each possible combination of strobe and return signals, and the other containing a different word which defines one of the functions that the system can perform.          When a particular key is actuated, the strobe/return signal output from the keyboard is compared with each of the strobe/return combinations stored in the first array.          When a match is found, a function identification word is retrieved from the corresponding memory location in the second array to designate the specific function that the actuated key is intended to produce.

Abstract: MASS AIRFLOW SENSOR          Abstract of the Disclosure An airflow sensor for a constant temperature anemometer comprises a copper foil resistor mounted on a polyimide foil which is supported in the airstream to be measured.  The support preferably is a flat frame having an aperture over which the foil sensor is mounted so that the airstream can strike the sensor on both sides of the film.  Airflow directors mounted upstream of the sensor are placed at an angle to direct the airstream toward each side of the film at a definite angle to obtain a positive cooling effect of the film by the airstream and consistent airflow.  The sensor assembly is mounted in a duct with the plane of the sensor along the longitudinal axis of the duct for measurement of the flow through the duct.  Another embodiment has a diamond shaped body mounted in an airflow such that a straight airflow impinges upon two forward sides of the body at a specific angle.  A dielectric film mounted on the forward surfaces sup-ports a metal film resistor on each face and a cavity in the body intersects the forward faces in the region of the metal film to isolate that film from the mass of the body to minimize the thermal mass of the sensor resistor element.

Abstract: Abstract An article inspection and cutting apparatus (10) is described for high production processing of elongated articles ( 12) such as raw potato strips (french fries). The apparatus includes a conveyor (20) for moving the articles (12) in line in a large number of transversely spaced lanes past an inspection (28) station and a cutting station (30). Scanning cameras (38, 40) at the inspection station (28) rapidly scan across the lanes to detect color or shade variation in the articles (12) and generate electrical signals characteristic of the defect. Rotating sets of knife wheels (54) are positioned at the cutting station for selectively projecting two or more knives (68) from the periphery of the wheel to cut sections of the article (12) containing the defect to separate the defective portion from the remainder of the article. The apparatus 10 has the capability of detecting the size of different shade defects and removing smaller dark defects and larger lighter defects.

Abstract: ABSTRACT         An engine speed governor is provided for exercising overriding control on a throttle regulating the flow of fuel to the engine.  A reversible motor is coupled to the over-riding throttle control means to drive it in a closed throttle direction or an open throttle direction.  An electronic circuit is provided controlling the motor for operation at respective high or low speeds according to the speed of the motor and the position of the throttle relative to a reference position.  The motor operates at its higher speed until the reference position is reached and thereafter at a lower speed, the lower speed being such that it is slower than the response capability of the engine to a change in throttle position, thus minimizing engine speed oscillation.

Abstract: A B S T R A C T         A compact, self-contained device for use in safely lowering filled beer kegs from the bed of a delivery truck to the ground.  The device includes a hollow drum rotatably carried within a sealed housing which can be removably inter-connected to a rigid support in the load bay of the truck.  A length of cable is wound about the drum and the free end thereof is connected to the keg chimes by means of a unique harness assembly.  When the keg is pushed from the truck the cable is uniformly paid out from the drum against the urging of a rewind spring.  The rate of descent of the keg to the ground is precisely controlled through a speed increaser housed within the drum which drives a novel centrifugal brake at high speeds producing a predetermined amount of drag on the drum.  Upon disconnecting the harness assembly the cable is automatically rewound on the drum by the rewind spring.
