Title: Device for controlling the movement of a door
Inventor: BISHOP ARTHUR EDGAR
IPC: E05F3/22
Filed: 1984-05-22
Abstract: A device for controlling the movement, particularly the closing movement, of a door (11) hingedly connected to a frame (10) comprises an arm (24) rotatable about a pivot (23) of a door closer device (22), the pivot being biassed to rotate in the closing direction of the door. The arm is rotatable against said biassing force to a position in which it is held against return movement by a pawl (43) of retaining means (30) which include an electro-magnet (33) and a keeper plate (34) which is secured to a flap (36) to which the pawl is pivoted. In use the arm (24) is normally held by the retaining means with the electro-magnet operated to hold the keeper plate and flap against releasing movement. In the event of a fire, however, the door must be closed and the electro-magnet is de-energised. The arm is thus released and rotates under the action of the biassing force. In one embodiment the arm (24) will contact the door to move it from an open to a closed position. In another embodiment, release of the arm (56) will allow rotation under the biassing force, of further arms which are attached to the door and thus close it. <IMAGE>

Patent GB-2151786-A (GB)
Title: Ultrasonic flaw detection
Inventor: SARGENT THOMAS HARRY
IPC: G01N29/06
Filed: 1984-11-26
Abstract: Flaws (12, 13), not readily detectable by pulsed ultrasound because of their location or orientation, are detected audibly by demodulating the pulse frequency of the ultrasound. A first shear wave probe (14) operating in the pulse/echo mode has located at a distance (d) behind it a second receiving probe (17). The first probe processes (15, 16) received signals using conventional ultrasonic techniques. The second probe, with a wider reception angle, demodulates (18) received signals to give an audio output (19). <IMAGE>
Patent GB-2156178-A (GB)
Title: Optical switching device and matrix
Inventor: OSBORNE DENNIS WALKER
IPC: H04Q3/52
Filed: 1985-03-15
Abstract: An optical switching device comprises a partially-reflecting surface (4) disposed in the path of an incoming beam to divert a portion of the light out of the incoming beam and a fully-reflecting surface (2) movable to intercept the diverted portion of the beam to effect switching of the diverted beam along an output direction. As shown, element 1 is longer than element 2. In the rest position (dotted line), the diverted portion passes over the top of mirror 2 to a sink. When it is desired to select the beam, the assembly is raised, the mirror 2 intercepts the diverted portion and directs it along the output direction. In a switching and routing matrix comprising an array of such switching devices, the reflectance of the surface (4) of devices in a row arranged to receive light sequentially, increase towards the end of the row remote from the incoming beam. <IMAGE>
Patent GB-2173589-A (GB)
Title: Bottle inspection apparatus
Inventor: GUNSHON STEPHEN
IPC: G02B27/64
Filed: 1985-03-18
Abstract: To detect dirt or a foreign body in transparent or translucent bottles, the bottles 1 are fed to an inspection station where the base of the bottle is illuminated by a lamp 4 through a diffuser 5. A Dove or Reversion prism 7 rotated by a motor 10 above the bottle mouth produces an image of the bottle base which rotates at twice the speed of the prism 7. A beam splitter 12 forms a rotating image on the photocell array 13 and a similar rotating image displaced in phase by 180 DEG  on photocell array 14. This enables the complete bottle base to be inspected in half a revolution of the prism, enabling the inspection rate to be doubled without increasing the rotational speed of the prism above a practical limit. <IMAGE>

Title: Torsional vibration damper with variable effect
Inventor: TEBBE GERHARD
IPC: F16F15/131
Filed: 1985-03-26
Abstract: A torsional vibration damper in the drive line of a motor vehicle with internal combustion engine comprises a mass 2 which is resiliently coupled to the drive line 16 through a lever arm r which is variable in dependence upon rotation rate by means of centrifugal weights 11. The natural frequency of the damper is therefore varied in a specified rotation rate range. The mass 2 may be connected to the centrifugal weights 11 and therefore to the hub 1 by rubber springs (9) instead of coil springs. <IMAGE>

Title: Soil cultivating implements
Inventor: VAN DER LELY ARY
IPC: A01B33/12
Filed: 1985-05-08
Abstract: In a soil cultivating implement comprising a hollow frame portion 1 that extends transversely to the intended direction of operative travel of the implement and supports a row of power-rotatable soil working members 2, a shield plate 11 is provided at least one end of the row. The maximum depth to which tines 5 of the members 2 can penetrate into the soil is adjustable and, in order to enable the plate 11 to maintain its substantially vertical dispostion for full co-operation with the neighbouring member 2 at any chosen working depth of the tines 5, a portion 14 of an arm 12 which carries said plate 11 can be entered through any appropriate pair of circular openings 17 in a front bracket 15 and a rear bracket that are both mounted on top of the hollow frame portion 1. The plate 11 can yield outwardly to release a momentarily trapped stone or the like before damage is caused by temporarily compressing the spring 24 of a resilient mechanism 18. Other constructions of the resilient mechanism are both described and illustrated. <IMAGE>
Patent GB-2175767-A (GB)
Title: Radar systems
Inventor: GWYNN PETER GLANVILLE
IPC: G01S13/528
Filed: 1985-05-28
Abstract: In a pulse doppler radar system target velocity ambiguities are removed and the velocity is determined by estimating the rate of change of the phase of radiation reflected by main targets at 12. Multiple within range cell sampling of the signal return is carried out at 6,7,8,9. For multiple targets, signals are transformed to the frequency domain from the time domain at 1,1' to distinguish between the targets prior to determining their velocities from the phase information. In the case of target velocities coinciding in the transform plane unambiguous operation is obtained by employing multiple pulse repetition frequencies to separate them. <IMAGE>
