Abstract: 1519493 Radiation curing of coatings ENERGY SCIENCES INC 10 June 1975 [9 Dec 1974] 24822/75 Heading B2E [Also in Divisions B5 and Dl]  A process for electron-beam curing of a coating comprises passing the coated substrate along a predetermined path, directing electron strip beam radiation through an electronpermeable window at a preselected region of the path with the radiation extending linearly along the path, accelerating the radiation in a direction substantially perpendicular to the path, adjusting the radiation within energy limits of from 50 to 30 KeV and with doses of 0.5-8 megarads in dependence of the thickness and materials of the coating and substrate so that a maximum amount of electron beam energy is concentrated in the coating to cure the coating, with minimum beam energy concentration in the substrate. The method may be used to apply a pressuresensitive adhesive to paper, vinyl, vinylasbestos, cork, wood, cotton, polystyrene, nylon, urethane film and leather. The method is also particularly suitable for application of coatings to strand-like substrates such as wires, cables, filaments, strings, yarns and threads. A reflector may be positioned behind the substrate to reflect the radiation back onto the coated substrate. In an embodiment the coating is first applied to release sheet, cured by radiation, a tie coat is applied to the first coat and the substrate applied to the tie coat.

Abstract: An insulation system for use in rocket motors containing solid composite propellants is disclosed. Some composite rocket propellants are based on carboxyl-terminated polybutadiene (CTPB) and others on hydroxyl-terminated polybutadiene (HTPB) binders. An important requirement of such systems is the ability of the wall insulation to adhere to the combustion chamber and of the composite propellant to adequately adhere to the insulation system. With CTPB propellants, a sheet insulant comprising chrysotile asbestos fibers and floats dispersed in a CTPB polymeric binder has been successfully employed. However, the use of a similar sheet insulant based on HTPB polymeric binder has not proved to be compatible with HTPB propellants. The present invention provides a composite sheet insulation system which is compatible with HTPB propellants including a first layer of sheet material comprising a CTPB binder having a mixture of asbestos fibers and floats dispersed in it and, bonded to it, a second layer of aluminum foil and an economical and effective method of lining a rocket casing propellant chamber, using the novel system of the present invention.

Abstract: An apparatus for dispensing documents from a storage location to a discharge area includes structure for transporting the documents from the storage location along a transport path to an escrow or collection station. The leading and trailing edges of the document are positioned in a holding position removed from the transport path at the collection station so that successive documents may be loaded into the collection station. The apparatus includes a double detector for separating two documents removed at the same time from the storage location and for returning all but one of the simultaneously removed documents to the storage location. When the proper number of documents have been collected in the collection station, they are moved along the transport path and deflected to the discharge area by a divert gate positioned in the path of the collection of documents. However, the divert gate is positioned to deflect the documents to a divert bin where there has been an error in discharging documents from the storage location to the collection station. Thereafter, the dispensing cycle is repeated.

Abstract: Pressurized water is fed to the driving cylinder 1 alternately through inlets 16, 17 in the end walls 5 and 6, causing reciprocation of both pistons 2, 4. Detergent or other additive is thereby sequentially drawn into cylinder 3 through valved inlet 18, forced through the valved bore 20 in piston 4, and expelled from cylinder 3 through valved outlet 19 in end-wall 7. It can then optionally be mixed with water from cylinder 1. Low-friction seals are provided by O-rings 2', 4', 15. For ease of maintenance and adjustment the cylinders 1, 3 are detachably and sealingly seated in annular grooves (10-13) in the end walls 5, 6, 7. The driven cylinder 3 is of smaller diameter than cylinder 1, thus giving a high pressure to the detergent. The output volume is adjustable via screw 43. <IMAGE>

Abstract: In an automatic gain control circuit specifically adapted to control the gain of an amplifier for operating a noise cancelling circuit, a detector is provided for detecting a detector input signal, such as detected noise pulses. The detector includes a differential amplifier comprising a transistor pair connected to a constant current source. According to the detector input signal level, the constant current is switched between the transistor pair. The normally off transistor of the pair is connected to a third transistor, through which a substantially invariant current flows to relatively slowly charge a capacitor in a time constant circuit when the input signal level exceeds a reference level given by the difference between a pair of bias voltages for the transistor pair. The voltage accumulated across the capacitor serves as an automatic gain control signal, which rapidly disappears when the input signal level decreases below the reference level. The automatic gain control circuit may additionally comprise a similar detector responsive to an amplifier input signal supplied to the gain-controlled amplifier for likewise charging the capacitor through the third transistor.
