Inventor: WILKINSON RICHARD L
IPC: G11B7/0045
Filed: 1979-03-27
Abstract: Apparatus and process for writing video information in the form of a frequency-modulated signal upon a disc member and for retrieving the recorded information. The disc member (10) formed by the writing apparatus is also described. The apparatus includes a laser (30) as a source of write light beam (29) and a write optical system for directing the focused beam to a moving disc member. The member comprises a substrate carrying a light responsive coating (26) at least on one surface. The write optical system includes an optical modulator (44) that charges the intensity of the write laser beam with respect to a predetermined threshold intensity sufficient to form a first type of indicia in the coating and a feedback apparatus that stabilises the operating level of said modulator. 
     The read optical system includes a light sensing circuit (158) for changing the intensity-modulated reflected-light beam to a corresponding electrical signal. 
     A triangular frequency modulator (Figure 14C) for driving a Pockels cell (68), for obtaining a sinusoidal-shaped light-modulation output signal from the linear polariser (70) and a bias circuit (264) employed for removing the second harmonic intermodulation distortion of the modulated write beam, are described.

Abstract: A molded porous silicon carbide body in the shape of an armor plate, made by coking a mixture of carbon and silicon powder coated with an organic binder to which some silicon carbide powder may be added, and then rapidly raising the temperature to a level at which silicon carbide is formed, is impregnated so that its pores are filled with steel or a steel alloy to produce a plate that has the hardness and stiffness of silicon carbide and the toughness of metal. The plate has superior resistance to hollow or shaped explosive charges. The lower density provided by the silicon carbide favors its use in armored vehicles.

Abstract: An externally powered twin-barrel machine gun includes a shuttle (42) having two firing chambers (64), 66). The shuttle linearly moves between two positions so that the firing chambers are alternately fed a round of ammunition and discharged. A feed system (21) has a pair of augers (23, 24) each with a helical groove (26) therein which receives a round of ammunition which obtains a dwell position on a zero pitched section (28) of the grooves. A ramming system (91) rams a round of ammunition to the firing chamber aligned therewith and simultaneously ejects any spent cartridge through a forward aperture (62) in the housing (16). The spent cartridge is frictionally engaged by an axially aligned acceleration belt (76) which quickly withdraws the spent cartridge from the firing chamber and accelerates it onto a deflection cam (88).
