Patent GB-2158755-A (GB)
Title: Improvements in or relating to plug drawing
Inventor: SANSOME DENNIS HUGH
IPC: B21C3/16
Filed: 1985-04-30
Abstract: A plug assembly for use in the plug drawing of tubes and like hollow workpieces comprises in axial succession, from front to rear, three parts in fixed relationship to each other: a foremost first part 18 with a smoothly rounded nose 22 to make smooth and positive contact with the tube at the start of drawing, a parallel-sided middle part 20 which sizes the interior section of the product as drawing proceeds, and a long rearmost part 24 of larger section. During drawing the confronting surfaces of the rear part and the bore of the undrawn tube define a thin cylindrical clearance 26, relative movement between the walls of which exercises a hydrodynamic action upon lubricant lying within the tube rearward of the plug, forcing that lubricant forward through the clearance into the region where tube and plug first make contact. Alternative plug shapes for the third part of the plug are proposed, including parallel-sided, stepped and sloping. <IMAGE>

Title: A positioning mechanism
Inventor: BILLINGTON ALAN JAMES
IPC: B07C5/36
Filed: 1985-11-18
Abstract: A positioning device comprises a pair of devices (50, 52) having extendible and retractable elements which have well-defined stroke limits and are collinear with each other. One device (50) is fixed and the other is mounted on a slideway (54) and carries a gate which can be displaced selectively into anyone of three well-defined positions by appropriate operation of devices (50, 52) to obtain different combinations of extension and/or retraction of the elements. The mechanism is used for diverting articles such as pellets from one feed channel (14) into a selected one of a number of feed channels (24, 26, 28) in accordance with the results of an inspection carried out as the articles progress along the channel (14). <IMAGE>

This construction enables the cable clamp to be easily released without the need for any unlock levers and offers a simple but secure locking mechanism. <IMAGE>
Patent GB-2188571-A (GB)
Title: Alignment systems
Inventor: WHITWELL ARTHUR L
IPC: B23Q17/24
Filed: 1986-04-05
Abstract: The operating head 22 of a machine tool or other instrument is positioned by an alignment system which detects the actual position of the operating head rather than that of a supporting carriage thereby eliminating any deformation in the arm or support structure which carries the operating head. The system preferably uses optical alignment/detection e.g. by means of a laser beam wherein an emitter carried by a sliding member 12 movable with a head support 16 but isolated therefrom by an appropriate linkage 14, directs a beam 18 to a detector 20 mounted in close proximity to the head 22. A signal indicating undesired displacement of the head may be processed by circuitry 24 and used as a feedback to effect corrective adjustment. <IMAGE>

Title: Spray heads
Inventor: DALTON MARTIN WALTER
IPC: B05B1/32
Filed: 1986-08-05
Abstract: A spray head includes a chamber in which three concentric rings 21, 31 and 41 are housed, and means to supply water thereto. An outer ring 21 is attached to the chamber, serrations 5 formed internally of the ring defining in co-operation with the wall of an intermediate ring 31 apertures through which water is emitted. Similar serrations 6 are formed on ring 31. At least one of the rings is moveable relative to an adjacent ring against a spring contained in the head. An annular O-ring is located between adjacent rings. The serrations are inwardly tapered whereby as the water pressure in the head increases and forces a ring outwardly relative to an adjacent ring, an increased flow of water is permitted through the aperture defined by the serration and adjacent wall thus maintaining a constant water pressure through the aperture. <IMAGE>

Title: Dosemeter
Inventor: STEPHEN JAMES HENRY
IPC: H01L27/144
Filed: 1987-01-09
Abstract: A dosemeter 10 includes a silicon chip 12 on whose surface 11 are defined a metal-oxide silicon (MOS) capacitor and at least one MOS field effect transistor 17. The MOS capacitor includes a capacitor electrode 36, electrically insulated by a silicon dioxide layer 28, but electrically connected to the gate electrode 30 of the MOSFET 17. A field-inducing outer electrode 40 enables the capacitor electrode 36 to be charged by electron transfer through a thin region of the layer 28, this thin region then returning to a very high resistance state. The charge remaining on the capacitor electrode 36 after irradiation of the dosemeter is a measure of the dose received, and can be measured non-destructively using two MOSFETs 17, 19 in a long tail pair network. The capacitor electrode may be completely surrounded by silicon dioxide, or alternatively one side may be exposed to a gas in a sealed can. <IMAGE>

Title: Intruder alarm system
Inventor: MACKINTOSH ALAN
IPC: G08B13/00
Filed: 1987-06-24
Abstract: The alarm system comprises a series of differently activated sensor devices 21,22 linked to a central controller 23. The central controller activates an alarm circuit only when the signals received from the sensors correspond to a pattern pre-determined as being consistent with the presence of an intruder. Thus spurious activations of single sensors will not activate the alarm thus lessening the likelihood of false alarms. <IMAGE>
