Abstract: ABSTRACT OF THE DISCLOSURE         A material or liquid level sensing system is dis-closed having a first triggerable pulse generator connected to a level sensor which is in turn connected to a second triggerable pulse generator wherein the first triggerable pulse generator supplies a pulse to the level sensor which transmits the pulse to trigger the second pulse generator for supplying an output both to an output device and to the first triggerable pulse generator to trigger another pulse to the level sensor and so on.  In this manner, the first pulse generator supplied a subsequent pulse to the level sensor depending on whether or not the second triggerable pulse generator has received the previous pulse from the first triggerable pulse generator.  Thus, the system continuously supplies pulses to the level sensor as long as the second triggerable pulse generator continues to receive pulses, but these pulses are blocked when the material or liquid being sensed is at a predetermined level and the output means is appropriately activated.

Abstract: TITLE  :  IMPROVEMENTS RELATING TO THE TREATMENT OF HIDES            ABSTRACT OF THE DISCLOSURE            A composition, a method and a tool are disclosed for treating tanned hides.  Flesh is removed from the hide by a novel tool comprising a rigid blade mounted on a handle and having a series of teeth projecting at one edge zone from a body of the blade, the teeth being generally V-shaped with chisel-like tips which are thin compared with the body portion of the blade.  After the flesh is removed from the hide, it is tanned and a composition is applied preferably by brushing onto the dermis.  The composition comprises a softening agent such as polyethylene glycol, a mineral oil and a surfactant which causes an unstable emulsion to be formed.  The glycol migrates into the epidermis and the oil migrates into the dermis to act as a lubricant to produce a supple or soft hide.

Abstract: INTERMETALLIC LAYERS IN THIN FILMS FOR IMPROVED        ELECTROMIGRATION RESISTANCE          Abstract A method and resulting structure for forming narrow intermetallic stripes which will carry high currents on bodies such as semiconductors, integrated circuits, magnetic bubbles structures, etc.  The conductive stripe includes aluminum or aluminum copper with at least one transition metal.  The aluminum and at least one transition metal are deposited onto a supporting body at a very low pressure in a substantially oxygen-free high vacuum.  The composite is then annealed at a temperature between about 200°C and 525°C for a time sufficient to form an aluminum and transition metal compound within the aluminum.  The conductive stripes are then formed by masking and removing portions of the annealed metallic material.  The resulting conductive stripes, which may be of a width of about 6x10-4 inches or less, have a significantly improved electromigration performance without significantly increasing resistance in the conductive stripe.

Abstract: OPERATING CIRCUITRY FOR SEMICONDUCTOR CHARGE COUPLED DEVICES        Abstract of the Disclosure Operating circuitry for linear charge launching, non-destructive weighting and non-destructive charge sensing for Charge Coupled Devices (CCD) employs electronic integrating circuitry at the input and output node terminals of the CCD.          Feedback circuitry within the integrating circuitry aids in linearizing the signals, in eliminating the non-linear capacitance effect of the depletion regions, and in freeing the design from device parameter variations such as elec-trode area and absolute values of threshold potential and thickness of insulating layer.  The circuitry is adaptable to most conventional CCD and is readily made up of conven-tional resistance and capacitance elements, of conventional comparing circuits such as differential amplifying or signal repeating circuits, and of conventional summing circuitry.

Abstract: ABSTRACT OF THE DISCLOSURE             A circuit for detecting documents jamed at the entry to an image fixing station in a copier in-cludes a latch-controlled timer.  Energization of a paper food clutch sets the latch to initiate a timing cycle.  A photoelectric circuit indicates whether the trailing edge of a document being fed to the image fixing station has cleared the entry.  The proper output from this circuit clears the latch and inter-rupts the timing cycle.  If the timer times out before the entry is cleared, the timer output is driven to a jam-indicating state.

Abstract: ABSTRACT OF DISCLOSURE         For translating the linear motion of a pivotally mounted thumb piece for a front door latch into the rotary motion needed to withdraw a latch bolt, two rotary members are employed.  One is a bell crank having a pivotal mounting on the mounting plate at one side of and at right angles to the pivotal mounting of the thumb plate and rotationally re-sponsive to linear motion of the thumb piece.  The other is a drum having a rotatable mounting on the mounting plate paral-lel to and spaced from the bell crank pivotal mounting, and at a location adjacent a roll back of a latch bolt.  A re-silient connector strip from the bell crank to the drum causes the drum to be rotated in response to rotation of the bell crank.  A torsion return spring attached to the drum acts to return the drum and the bell crank to their original positions.

Abstract: METHOD OF REDUCING ARCING IN A GAS TRANSPORT LASER          ABSTRACT OF THE DISCLOSURE           The method of reducing arcing in a high power gas transport laser consists of introducing molecular oxygen into the carbon dioxide mixture in which the glow discharge takes place.  The oxygen may be in pure form or may be mixed with nitrogen as in air and is admitted to the recirculating gas mix-ture in predetermined quantities during operation of the laser. The effect of this addition of oxygen to the circulating gas mixture is to prevent the formation of oxide coatings on the copper electrode surfaces, and specifically on the cathode, thereby eliminating this cause of arcing in the laser.

Abstract: METHOD AND APPARATUS FOR DETERMINING THE VELOCITY OF A LIQUID STREAM OF DROPLETS                   Abstract of the Disclosure A pressurized ink jet stream is broken up into droplets spaced substantially uniform distances by application of a predetermined frequency to the stream.  When the velocity of the stream is to be determined, a frequency perturbation is placed in the predetermined frequency to produce a gap in the stream of droplets at a selected distance from the perturbation application point.  The presence of the gap is optically sensed at the selected distance by determining when the time period between adjacent droplets at the selected distance exceeds a predetermined period of time.  The velocity of the stream is determined in accordance with the time that it takes from the perturbation of the gap until the gap is sensed at the selected distance because of the time period between adjacent droplets exceeding the predetermined period of time.  After the velocity of the stream is determined, it is compared with a desired velocity, and corrections in the pressure of the stream are made in accordance with the difference between the determined velocity and the desired velocity and whether the determined velocity is larger or smaller than the desired velocity so that the velocity of the stream can be corrected to be within a predetermined range of the desired velocity.

Abstract: ABSTRACT OF THE DISCLOSURE     The present invention relates to reading of stored information from a videodisc.   Attempts have been made in the prior art to read information from video-discs to produce a video signal having its amplitude varying with time.  Through the entire process of re-cording to reading, however, poor quality of the repro-duced signal can result due to the format of the recorded signal and the manner of reading.  The present invention overcomes these deficiencies by providing an improved apparatus and method for reading stored information on videodiscs, the information being in the form of a lineal series of regions of alternately high and low reflectivity in a direction normal to the disc surface. In accordance with the invention, the reading system includes a polarized collimated beam of light, and an optical system between the light source and the video-disc for focusing the reading beam upon the videodisc. Relative motion is provided between the reading beam and the alternate regions for generating reflections from the high light reflective regions on the video-disc.  A light sensor is responsive to the reflections for generating a frequency modulated electrical signal caused by the reflections.  The reproduced frequency modulated signal has its informational content in the form of a carrier frequency which has a frequency vary-ing with time.
