Title: Phase balancing of two-channel amplifier - involves using digitisation and phase comparison of continuous channel output signals
IPC: H03L7/081
Filed: 1970-06-18
Abstract: An arrangement is used for balancing two data channels of a two-channel amplifier and its associated phase discriminator. It uses digital technology for improved accuracy and economy w.r.t. conventional arrangements. The arrangement may be applied to monopulse radar receivers, passive direction finders, and control systems. Two separate pulsed signals are derived from the two channel pilot signals. One forms a reference signal. The sign of the phase difference between them is derived. A third pulsed signal width modulated according to the phase difference and containing a super-imposition frequency maybe converted to a continuous signal.

Title: Ballistic rocket for generating underwater blast - is detonated from tail for producing downwards directed blast bubble
IPC: F42B12/32
Filed: 1972-02-02
Abstract: The warhead of a ballistic rocket used for underwater application has an explosive charge which is initiated at a predetermined immersion depth after the projectile has entered the water with the nose first from the air. The enveloped explosive charge is exploded so that the gas bubble formed is initially directed downwards to increase shock effect on nearby submarines or surface ships. The sheathed, enclosed explosive charge (5) is an explosive producing a high volume of gases. For this purpose the explosive may be mixed with aluminium powder. The initiation point (8) at the projectile tail (4) ensures that the explosive pulse is directed downwards, away from the water surface.

Abstract: The pattern matching method and apparatus described herein comprises a step of determining a distance d(m,j) between each feature vector b@ of a reference pattern and a feature vector am of an input pattern at each point (m,j) of the i-th block defined in the form of a parallelogram which has the IL frame width of an input pattern and is inclined with respect to said reference time axis, a step of conducting DP matching calculations on the basis of the distance determined; and a step of setting the boundary value of an (i+1) -th slant (oblique) block at values at such a slant line contacting with an i-th block as is obtained by said DP matching thereby to effect said DP matching calculations. This pattern matching method and apparatus can recognise at a high accuracy and at a high speed an input string of words spoken in compliance with various grammars. Furthermore the DP matching can be processed at a high speed with less transfer of pattern data and with less capacity of pattern buffer memories.

Abstract: A hot sprue valve assembly is provided for controlling flow of molten material into the mold cavity of an injection molding machine. The valve assembly is particularly designed for use with an injection molding machine for molding centrally apertured record discs, such as video information discs. The valve assembly comprises a stationary valve body supporting a movable valve member for sliding motion toward any away from the mold cavity. The valve member includes a hot sprue bushing defining a heated flow path for passage of molten material toward the mold cavity, and a dispersion head carried by the bushing for directing the molten material to flow in a generally radially outward direction through gate passages with substantially uniform radial distribution into the mold cavitiy. In one position, the valve member is advanced into the mold cavity to align the gate passages with the mold cavity and thereby permit flow of the molten material into the mold cavity. The valve member is movable to retract the gate passages from alignment with the mold cavity to prevent flow of the molten material into the mold cavity. In this retracted position, a portion of the dispersion head remains within a central portion of the mold cavity to mold a central aperture into the disc prior to soldification of the molten material.
