Title: Darts
IPC: F42B6/00
Filed: 1981-01-28
Abstract: A shaft unit for a dart uses a plain wire shaft 3 which is secured to a flight retaining part 4 at one end and a barrel connector 1 at the other end by means of collets 4b and 1b respectively which have plain bores to receive the shaft ends.

Title: Controller for coupling power to an N phase load
IPC: H02P1/26
Filed: 1981-03-12
Abstract: An N phase induction motor 11 having a torque that is considerably higher during starting than while running during normal operation is selectively connected, during the starting period, to an N phase power line source  phi a,  phi b,  phi c, and during normal operation to an N phase, variable frequency pseudo- sinusoidal switching converter 21, 22, 26. In response to a phase and frequency lock being achieved between the pseudo- sinusoidal and power line powers, power from power line terminal K for phase K is decoupled from the motor winding for phase K, as pseudo-sinusoidal power of phase K is being applied to the winding for phase K, where K is selectively and sequentially 1, 2 ... N. The reverse operation is performed in response to a change command signal after a phase and frequency lock has been achieved between the pseudo-sinusoidal and power line power.   <IMAGE>

Filed: 1981-04-21
Abstract: A system for descriminating a human voice signal from other sounds comprises a mixer 24 having two input channels and connected to a high pass filter 25 for removing subsonic sounds below 20 HZ. The output of the filter 25 is connected through a low pass filter 3 to the input of a voltage controlled variable gain amplifier 4, the output of which is connected to a body-felt vibration generator. The output of filter 25 is also connected through an equalizer 26 and a signal level compressor 27 to the inputs of a double bass sound region deriving circuit 28, a level detector 8, and a human voice fundamental wave emphasizing and deriving circuit 9. The double bass circuit 8 includes a low pass filter having a cut-off frequency of 60 Hz. The circuit 9 derives the fundamental human voice sound wave by regarding the human voice as an amplitude modulated wave with the fundamental waves generated in the vocal cords being regarded as the modulating waves and the formants imposed during passage through the vocal tubes as the carrier wave. The circuit 9 includes a detector and a band pass filter. The outputs of the circuits 28, 8 and 9 are connected to the inputs of an arithmetic circuit 10, the output of which is connected to the control terminal of the amplifier 4. In use, the amplifier 4 suppresses double bass signals originating from a human voice but passes other double-bass signals. <IMAGE>

Patent GB-2096942-A (GB)
Title: Saw
IPC: B27B9/00
Filed: 1982-03-16
Abstract: Motor 17 is mounted for swinging about an axis provided by spindle 19 for saw blade 14 to be withdrawn into guard 13 or to protrude through base plate 10 which is connected to bedplate 26, having guide flange 31, by pivot bolt 27. Spring 37 loads the bedplate towards an inoperative position in which guide flange 31 is parallel to the plane of the blade 14. When swingable arm 33 is brought to its illustrated position it turns eccentric body 32 to cause the blade 14 to be angled relative to the guide flange 31 and it brings stop 34 into an operative position limiting the downward protrusion of the blade by providing an abutment for the motor 17. This arrangement enables a shallow slot of width greater than the blade thickness to be made during a first traverse across a workpiece (with the saw teeth attacking the workpiece on entry and thereby avoiding chipping of any surface facing) and the workpiece to be cut right through in a subsequent traverse. <IMAGE>

Title: Electronic timepiece
Inventor: YABE HIROSHI
IPC: G10L25/78
Filed: 1982-10-04
Abstract: An electronic timepiece with voice memory includes an auto start circuit which senses the presence of an input voice and automatically controls the start of recording. Voices inputted from the outside are coded and the coded data is stored in memory. An output means reads out the memory contents and transforms the coded contents into an analog voice signal. When the incoming voice exceeds a predetermined level, the recording means is automatically started by an output from a level detector. Memory is divided into at least two regions. The first region stores coded voice data before the auto-start circuit operates and later coded voice data is recorded in the second region after the autostart circuit operates so that the initial portions of speech are not lost.

Title: Controlling nuclear magnetic resonance analysis
Inventor: ASPIOTIS EVGENY KHARLAMPIEVICH
IPC: G01R33/46
Filed: 1983-11-12
Abstract: In a method of analysis a weighed sample, nuclear magnetic resonance (NMR) signals are obtained therefrom during a succession of measuring cycles. During each cycle, computation is made of the mean value of the NMR signals and of a standard deviation thereof. The standard deviation is subtracted from a permissible limiting standard deviation value and the signal accumulation is stopped when the difference is positive. This is followed by the steps of computing a mean value of the NMR signals and determining percentage of components in the analyzed sample with regard to its mass and the mean value of the NMR signals. The method is primarily intended for analyzing on a mass scale oil seeds and associated processed products to determine a fat and water content.

Title: A submarine countermeasure system
Inventor: MORRIS JOHN CHARLES
IPC: G01S7/00
Filed: 1984-01-10
Abstract: A countermeasure system for defending submarines against homing torpedoes, comprises a detector that is responsive to active sonar transmissions, and a transmitter which produces matched transmissions for jamming the torpedo. Broad-band transmissions may also be produced for jamming passive torpedoes and for jamming active torpedoes where the matching is inadequate. A memory store of threat signatures improves matching. At least part of the system is housed in a body to be launched from the submarine upon detection of a threat. Matching may be done manually or automatically prior to launch, or, after launch, if a link, e.g., a fibre-optic, is maintained between the body and the submarine. The transmitter circuitry may be self-adaptive.
