Title: Frequency comparison arrangement for a digital tuning system
IPC: H03J5/02
Filed: 1981-04-03
Abstract: In a tuning system including a station selector (15/17,19) for generating a digital word representative of a selected channel, a counter (25) for counting periods of a local oscillator signal during a measurement interval to generate a digital word representing the accumulated count, and a comparator (33) for generating control signals for the local oscillator (5) in accordance with the deviation between the station- representative and count- representative digital words, apparatus is provided to enable the number (eight) of bits in the count- representative digital word to be less than the number (thirteen) of bits in the station-representative digital word. Specifically, the tuning system operates in coarse, medium and fine tuning steps. During each step a predetermined group of bits derived from the station-representative digital word are selected (45) for comparison with the count-representative digital word and the duration of the measurement interval is set (27) in accordance with the bits selected. <IMAGE>

Title: Pulse shaping circuit
IPC: H03K5/1252
Filed: 1982-03-11
Abstract: In a keyboard e.g. a telephone push button keyset, to avoid the disturbing effects of contact bounce, each of the row (X1-X4) and column (Y1-Y3) conductors is connected via an RC filter (e.g. R1, R10, C1) to a respective one of a set of flip-flops (FF1-FF7). Also connected to these flip-flops are the outputs of a gating network (NG1-2-3-4) which enables the flip-flops as long as the voltage on a capacitor C8 exceeds the threshold of NG3. C8 is charged as long as at least one of the X filters or at least one of the Y filters is producing an (actuated) output, and proceeds to discharge when neither of these two conditions obtains. <IMAGE>

Title: Vehicle with multi-directional movement capabilities
Inventor: STEDMAN ROBERT N
IPC: B62D57/00
Filed: 1982-01-11
Abstract: Mobile vehicles, such as lift trucks, are normally mounted on pairs of front and rear wheels for locomotion purposes. The rear wheels are steerable to move the truck into various work positions.

Title: Horn assembly for ultrasonic welding machine
Inventor: RAWSON FRANCIS FREDERICK HAMIL
IPC: B06B3/00
Filed: 1983-05-25
Abstract: A horn assembly for use in an ultrasonic welding machine, when operating with a frequency of the order of 20 KHz, with a tip amplitude of 40 to 80 microns, and under an applied load of the order of 200 Kg force, for an operating cycle of 0.6 to 1 second, comprises a horn member (32) having a profiled work-engaging surface and a further member (30) connecting the horn to a transducer. The horn member (32) is secured to the further member (30) by a stud (34) having two threaded portions (36, 38) with an intermediate smooth-surfaced portion (40) of reduced diameter. The length of each threaded portion (36, 38) of the stud is proportional to its diameter, according to the strength of the member into which it is screwed. Also, the thread of each threaded bore (42, 44) is spaced from the open end by a distance equal to not less than two turns of the thread. Further, the threaded bores are not subjected to any surface treatment. These various features serve to mitigate the tendency of the stud and/or the members to fracture. <IMAGE>

Title: Method and apparatus for shaping fiber mats
Inventor: TIMMS DONNY LEE
IPC: D04H1/60
Filed: 1983-08-10
Abstract: Method and apparatus for shaping of mats 80 composed of loose fibers with a thermosetting resin interspersed throughout. The apparatus compresses the mat and exposes its laterally extending surfaces to elevated temperatures to obtain partial curing thereof. Slits 86, 88, 90 are made in the surface regions adjacent areas where extra shaping will occur in forming the final product. These slits enable more precise shapes to be impressed upon the mat and eliminate the tendency of the partially cured areas to spring back to a position of lesser compression. <IMAGE>

Filed: 1984-01-23
Abstract: A flexible sealing boot 13 for a rotary component such as a sliding spline assembly or a universal joint, has an annular attachment portion 15 which seals by its own resilience on a part of the component and is arranged to lift therefrom under centrifugal force in use to provide a vent passage to the interior of the boot. The boot may have an additional mass 19 of the same material as the boot provided at one place on its annular portion to lift under centrifugal force. If the attachment portions of the boot are of different diameters, it is usually preferable for the one of smaller diameter to lift under centrifugal force. <IMAGE>

Title: Proximity fuse.
Inventor: SCHMIDT HUBERT
IPC: F42C13/00
Filed: 1984-02-27
Abstract: The invention relates to a proximity fuze for projectiles (rounds) having at least one sensor where the variable which is monitored by said sensor changes on approaching a conductive body and is utilised to initiate detonation. Frequency changes which occur in the sensor oscillator as a result of production tolerances, aging processes and temperature effects in the components are compensated for immediately with the aid of a follow-up synchronisation circuit, so that there is no longer any need for circuit tuning (calibration). The high sensitivity of the fuzing circuit is maintained when the projectile approaches the target by means of two selectively acting control loops.
Patent GB-2137669-A (GB)
Title: Yarn winding apparatus
Inventor: HERMES JULIUS
IPC: B65H54/74
Filed: 1984-03-22
Abstract: Yarns which have been heat set and cooled are wound onto a spool by one of a plurality of winding units in a yarn separating device. The device has a central drive means which drives belts (28) to rotate cam rollers (36) each driving two winding units. These units, each of which includes a grooved friction drive roller (53) for feeding yarn onto a spool (58), are coupled to the cam roller by an eddy current coupling unit (45). This unit has two drive plates, one with a magnetic layer and the other with a current carrying layer, separated by a manually adjustable gap. By adjusting the gap, the torque imparted to the grooved cam roller can be varied to vary yarn tension. This tension/torque control mechanism permits yarn to be wound onto spools at a uniform tension. In the heat setting and cooling apparatus, yarns are deposited on a perforated conveyor belt and heated (for bulking) and cooled by air (Fig. 1, not shown). <IMAGE>
