Title: Reproduction system for stereoscopic photographic views on disc - contains separately controlled motors for synchronised operation of audio and photographic view discs
IPC: G11B27/19
Filed: 1982-09-08
Abstract: A plastics disc is provided with stereoscopic pairs of photographic views located on concentric circular paths over its surface. Indicator holes are located around the periphery at an interval corresp. to the number of views. A normal sound disc has indicator holes located around its periphery and both discs are contained in a casing for protection and to maintain their relative positions. This casing is mounted on a turntable supported on a chassis and driven by a belt from a motor. This allows the sound disc to be played while a second motor drives a vertically mounted wheel to rotate the visual disc. Photodetectors adjacent to the indicator holes enable the discs to be controlled and synchronised.

Title: Quenching streams of molten mineral material - to form mineral fibres of non-circular cross=section and high mod ratio
IPC: C03B37/083
Filed: 1986-10-06
Abstract: Non-circular mineral fibres having a mod ratio greater than about 1.2 are made by discharging molten mineral material having a liquidus greater than about 1200 deg.F from non-circular orifices to produce molten streams of non-circular cross-section. The orifices are positioned in a wall of a container for holding a body of the molten material. The material in the streams would assure a circular cross-section in the absence of quenching. The streams are then quenched to harden them into mineral fibres having a non-circular cross-sectional shape similar to that of the orifices before the streams can assume circular cross-sections.

Abstract: ABSTRACT       A transmission system for pulse signals of fixed clock frequency with regenerative repeaters located in the transmission path, each being provided with a pulse regenerator and a clock extraction circuit recovering the clock frequency for the control of the pulse regenerator from the received pulse signals with the aid of a frequency selective circuit. Especially in transmission systems having a large number of regenerative repeaters, a considerable reduction of the phase jitter of the recovered clock signal in the receiver can be achieved without detrimentally influencing the acquisition of the clock frequency in the individual regenerative repeaters by employing a frequency selective circuit that has a normalized phase transfer function whose absolute value as a function of the frequency is substantially constant from the frequency zero to a first corner frequency, monotonously decreases from the first corner frequency to a second corner frequency, is again substantially constant from the second corner frequency to a third corner frequency and again decreases monotonously for frequencies which are higher than the third corner frequency.

Abstract: Safety Switch For Drill Press Using Chuck Key Abstract of the Disclosure.  The subject safety switch insures that the chuck key has been removed from the chuck prior to operation of the drill press.  A slide "on-off" switch is engaged by a guard that prevents the sliding movement necessary to turn the switch on.  The guard of the safety switch is not part of the electrical circuit, but rather is a mechanical addition which prevents operation of the electrical circuit.  The socket is formed in the housing adjacent the guard.  The chuck key is inserted into the socket to engage the guard and remove it from the path of travel of the switch to permit the switch to be shifted between the on and off position.          The socket is keyhole shaped, whereby insertion of the chuck key therein will force the chuck to seat within the lower narrower aperture thereof.

Abstract: Abstract of the Disclosure The gate latch is intended for use with gates which are capable of swinging through an arc of approximately 180 degrees  The latch finger secured to the gate may therefore pass through the latch if desired. The latch includes a hollow body secured to the gate post. A slot in the front wall of the body allows the latch finger to pass therethrough and one or more pawls are rotatably mounted in the body so as to trap the latch finger.      In one embodiment, a pair of pawls is provided and the latch finger engages one pawl which rotates out of its path and the latch finger is trapped between the pawls as the pawl returns to its rest position due to the action of gravity.        In another form  of the invention a single rotatable pawl has a notch to engage the latch finger as the gate swings to the closed position. The pawl is then held there by co-operating means on the pawl and on he lower wall of the latch until it is released manually.

A method is also disclosed of aligning the body of monocrystalline material with respect to the saw blade for sawing, in which the body is mounted in a positionable sawing fixture, and an observation of the first pattern the orientation of the enclosure with respect to the predetermined crystallographic plane is made.  The orientation of the plane of the saw blade with respect to the enclosure is then deter-minded by observation of the second pattern.  The sawing fixture is then positioned to orient said crystallographic plane with respect to the saw blade plane on the basis of these determina-tions.

Abstract: ABSTRACT      Semisolid polymerizable compositions are obtained by combining unsaturated polyester resin syrup, aqueous alkali-stabilized colloidal silica and finely divided particulate calcium sulfate hemihydrate.  The composition rapidly thickens to a semisolid state when the ingredients are mixed and retains its semisolid condition for extended periods of time.  The unsaturated polyester resin syrup component of the mixture remains polymerizable until its polymerization is initiated, normally by means of heating in the presence of a high temperature polymerization initiator.  Sufficient calcium sulfate hemihydrate is included to react with sub-stantially all of the uncombined water in the other ingre-dients so that the resulting polymerizable composition is substantially free of uncombined water.  The compositions may also contain inert fillers and/or reinforcing fibers.          The compositions can be employed to produce coatings, laminates, cast articles, molded articles and other shaped articles.    The compositions may be employed in either of two alternative procedures.  In the direct processing of the compositions, they are mixed, immediately formed and imme-diately polymerized to produce useful products.  In the two stage processing of the compositions, they are mixed, allowed to thicken without polymerization and are retained as a semisolid polymerizable composition which is useful as a molding compound in the form of dough molding compounds, sheet molding compounds or molding powders.  In all of these procedures, the preferred compositions include reinforcing glass fibers as an essential ingredient.
