Patent GB-1191299-A (GB)
Title: Improvements in or relating to processes for the Manufacture of Impregnated Electrical Capacitors
IPC: H01G4/22
Filed: 1967-12-22
Abstract: 1,191,299. Capacitors. SIEMENS A.G. 22 Dec., 1967 [23 Dec., 1966], No. 58368/67. Heading H1M. The dielectric in an impregnated wound capacitor comprises foils of plastics material which is swollen by the impregnant. The swelling of the dielectric fills up gaps which would otherwise be filled with the impregnant and have lower breakdown resistance. The tightness of the capacitor roll may be controlled so that swelling does not interfere with impregnation. Alternatively impregnation may be carried out at a low temperature when the rate of swelling is low, and the temperature then raised to accelerate swelling. The dielectric material may be polypropylene; the impregnant insulating oil containing 15 to 20% aromatic constituents, 30% naphthenes and 50 to 60% paraffins. The electrodes may compries foils of insulating material such as paper metalized on both sides, the insulating material accordingly lying in the field-free space of the capacitor.

Title: Apparatus for regulating the position of a laser light source transmitting a light beam
IPC: G01S7/48
Filed: 1973-12-18
Abstract: 1413698 Automatic control of light beam position WERKZEUGMASCHINENFABRIK OERLIKON-BUHRLE AG 18 Dec 1973 [18 Dec 1972] 58548/73 Heading G3R The position or orientation of a laser light source 11 Fig. 1 transmitting a light beam 6 is automatically adjusted as a function of the position of the transmitted light beam with respect to a detector 20, whereby to stabilize the beam direction. The forward end of the laser light source 11 is universally suspended, being pivotal about a vertical shaft 21 in a frame 22 which is pivotal about a horizontal shaft 23. The position of the rear end of the source 11 is adjustable by elements 25, 26 effective in two mutually perpendicular directions perpendicular to the plane of the beam. The elements 25, 26 Fig. 2 have iron cores 27, 28 respectively, biased by compression springs 29, 30 and extending into coils 35, 36 respectively. If the light beam 6, which passes through a passage 17 in a carriage 5, moves from the centre of the detector 20 then signals from four outputs thereof will have different values and differential amplifiers 37, 38 produce respective difference or error signals which are applied to controllers 39, 40. The cores are normally held within the coils against the spring biases by a continuously applied direct current, the degree of retraction of each core within a respective coil depending upon the magnitude of this current. When a position error occurs the resulting difference currents are superimposed upon the said direct current and the adjustment elements are thereby driven to restore the original beam direction. Beam detectors 8, 9, 10 determine the position of the carriage with respect to the beam 6.

Abstract: 1406999 Automatic exchanger systems TELEFONAKTIEBOLAGET L M ERICSSON 20 Dec 1972 [22 Dec 1971] 58936/72 Heading H4K In an exchange used for inter-highway switching, the required outgoing highway and time slot addresses are stored in association with each sample to be switched, a clock generates outgoing time slot addresses, the generated addresses are compared with each stored time slot address and upon a match being detected the associated sample is fed to the highway specified in the associated highway address. The exchange shown switches between incoming and outgoing PCM highways 1 to n. The PCM samples on each incoming highway are each converted to parallel form in a register such as PCW1 and entered into a storage register such as SW1 permanently associated with the incoming time slot. In respect of incoming highway 1 for example the speech samples occurring with one time frame are distributed sequentially to storage registers SW1 to SW32 associated individually with the time slots on that highway. A marker M enters in storage registers OLA and OCA (individually associated with registers SW) the corresponding outgoing highway and time slot addresses. A clock (CLOCK) generates in sequence the 32 time slot addresses for the outgoing highways and comparators COMP 1 to COMP 32 compare these addressed with the time slot addresses stored in registers OCA. Whenever a match is detected the corresponding comparator enables a gate arrangement AND to gate the corresponding highway number and speech sample from registers OLA and SW to a corresponding decoder DEC which routes the speech sample on to the highway specified.

Title: A process for recording and analysing picture information obtained from pulse-echo sectional scanning
IPC: G01N29/06
Filed: 1978-11-06
Abstract: The invention relates to an apparatus for recording and analysing picture information by pulse-echo sectional scanning e.g. ultrasonically of a biological material comprising at least two substances with internal interfaces. The scannings are performed by means of transducers (1, Fig. 1, not shown) arranged along a row surrounding the material completely or partially. The transducers are sequentially excited, and information about the position of the individual transducer together with the echoes is recorded in a memory 3 and analysed by means of a central processing unit 5 for pattern recognition. As a result the scanning and analysing can be performed irrespective of the position of the material relative to the row of transducers. The stored data is analysed to give a computer graphics display (Fig. 3, not shown) whereby thicknesses of lard (S) and meat (K) in a pig section can be obtained. <IMAGE>

Patent GB-2013386-A (GB)
Title: Electronic sound processing device
IPC: G10H1/38
Filed: 1978-12-11
Abstract: An electronic processing device takes the form of a musical electronic instrument which can be "played" using an input signal such as a human voice. An intelligent data processing system, for example a micro-processor system, within the instrument corrects the pitch of the voice input to the nearest semi-tone (on an "equally tempered" scale). The corrected signal is then amplified and fed to an output loud-speaker. The instrument incorporates operator- controlled means to switch the output up or down by one or more octaves in relation to the corresponding input signal. The data processing system within the machine can be so programmed as to sense the musical key in which an input melody is being played, and make available to the operator a series of chords appropriate for accompanying the melody in that particular musical key. It can also sense when a change of key has occurred, and change the available chords correspondingly. <IMAGE>

Title: Automatic Parachute Releaser
IPC: B64D17/58
Filed: 1979-03-21
Abstract: A parachute system formed by a main chute and a reserve chute (16) has an automatic parachute releaser for the reserve chute which includes a sensor (44) detecting an increasing fall rate of a payload above a trigger level to initiate a timing cycle in a timer (88). If the timing cycle is completed, a single-action actuator (38) automatically releases the reserve chute independently of the main chute releaser. Should the rate of fall decrease below trigger level during the timing cycle because of late opening of the main chute or timely manual release of the reserve chute through its ripcord assembly (20), then automatic operation of the actuator is cancelled by automatic reset of the timer in response to cessation of the triggering signal from the sensor. <IMAGE>
