Patent GB-2082709-A (GB)
Title: Disc nut and disc-headed bolt
IPC: F16B23/00
Filed: 1980-08-23
Abstract: A nut or bolt head is formed as a disc which is provided in one face with two, three of four blind or through holes or depressions or slots, for engagement by a suitable tool. The nut may be applied to a conventional threaded rod or bolt, or to a disc- headed bolt, in order to secure one timber member to another or to secure a timber member to a metal one. The disc nut or disc-headed bolt may replace the conventional nut or bolt whilst eliminating the need for any washer. The disc nut and disc-headed bolt can significantly enhance the appearance of structural timber joint assemblies particularly when recessed partially below or flush with the timber surface. In the latter application it also has significant advantages as a deterrent to vandals in locations which are vulnerable to their attentions. <IMAGE>
Patent GB-2057964-A (GB)
Title: Producing padded wearable articles
IPC: A43B13/38
Filed: 1980-09-08
Abstract: A protective and/or supportive article is moulded in two stages, namely, a first stage in which a substrate of hard plastics 10 (Fig. 7) is formed, and a second stage in which a soft, resiliently yieldable plastics coat 22 (e.g. foamed plastics), is formed on the hard substrate with simultaneous bonding thereto. During the moulding under heat and pressure, flanges 13/26 of waste material are produced on shoulders of the mould, and serve to prevent leakage of the yieldable material 22 onto side surfaces of the hard plastics 10. There is thus provided quickly and efficiently an article having the strength required for protection and/or support and the comfort required for wear. This invention is especially suited for the production of insoles (Fig. 9) for footwear, shinguards and kneepads, such as an insole having a suitably contoured top surface 24, 25 designed to increase the comfort and support afforded by the footwear. <IMAGE>

Patent GB-2095041-A (GB)
Title: Magnetic cores
IPC: H01F27/25
Filed: 1981-03-13
Abstract: A curved lamination magnetic core comprises magnetic strip material forming a laminated closed loop, the laminations being bonded together over a first part of the circumference (above the line 4,4) and unbonded over a second, major part (below that line). A single cut (5) extends through all the laminations at a position in the first, bonded part of the circumference. The position of the cut is such that the closed loop can be sprung open at the cut by flexing in the second, unbonded part of the circumference without any substantial deformation of the bonded laminations in the first, bonded part adjacent to the cut. In this way the core can be assembled with a pre- wound electrical coil in a single simple operation without requiring two joints, and an abrasion-cut joint can be used without machining treatment. <IMAGE>

Patent GB-2115734-A (GB)
Title: Pneumatic drawing device
Inventor: REIHLE MARKUS
IPC: B21D24/02
Filed: 1983-01-21
Abstract: The invention relates to a pneumatic drawing device with a pressure cheek 1 guided in the press bed and supported by at least one pneumatic cylinder 7, which cooperates with a hydraulic locking or retaining device 25 active at the bottom of stroke of cheek 1. In order to increase the number of strokes of the machine and to reduce the noise level when ejecting the workpieces in a device of this type, a pin plate (2) supports ejector pins (3), whereas acting on the lower side is at least one piston rod (4) guided through the pressure cheek (1) of additional compressed air cylinder(s) (5) incorporated in the pressure cheek base. These additional compressed air cylinders receive a pressure which is exactly sufficient to lift the workpieces into the conveying plane by the ejector pins. Thus, while the pressure cheek 1 is retained at the bottom dead centre, the pin plate with the press ram (not shown) once more travels upwards directly after the drawing operation. Subsequently, the pressure cheek may then travel upwards slowly and only needs to have reached the upper dead centre shortly before the beginning of the next drawing operation. <IMAGE>

Title: Novel substituted thiophene azines and derivatives thereof
Inventor: HOUGHTON PETER GRENVILLE
IPC: C07D333/28
Filed: 1983-05-04
Abstract: A process for halogenating and, if desired, subsequently nitrating a 2-acylthiophene, the acyl group being of formula RCO- wherein R is hydrogen or an alkyl group of 1 to 10 carbon atoms, comprises an initial step of reacting the 2-acylthiophene with a hydrazine reactant, to form the corresponding azine and thereby protect the acyl group against unwanted reactions. After the halegenation and any nitration step, the substituted azine obtained can be converted to the desired substituted acylthiophene by hydrolysis. The halogenated and possibly nitrated azines are novel compounds of the formula   <IMAGE> wherein R is H or C1-10alkyl, X is halogen and Y is H or NO2. They are useful as intermediates in the production of azo dyes, the corresponding acylthiophenes being aminated and then diazotized.

Title: Optical sensor
Inventor: DAKIN DR JOHN PHILIP
IPC: G01L1/24
Filed: 1983-08-24
Abstract: An optical sensing system comprises two optical fibre sensors 2,3 of different lengths connected in parallel and arranged to be subjected at 5 to deforming forces; pulse laser 1 which transmits signals simultaneously along the optical fibres; optical coupler 7; three optical fibres 8,9,10 each with a plurality of equally spaced reflective discontinuities (11, Fig 2, not shown) which define along each fibre 8,9,10 sensor a plurality of fibre elements so that the fibres 8,9,10 in combination are equivalent to a fibre with discontinuities over a length equivalent to the longest fibre 10. A small proportion of each light signal transmitted along each fibre 8,9,10 will be reflected back along the fibre 8,9 or 10 from each of the discontinuities (11) whereby each reflected light signal after the first in each of the fibres 8,9,10 interferes with either the previously reflected signal from the preceding discontinuity of the same fibre, or a reference signal from fibre 3 to cause photodetector 12, to which all the sensors are coupled, to produce an electrical signal, the difference between successive electrical signals corresponding to successive discontinuities (11) in the fibres being dependent upon the length of the fibre elements 2,3. Changes in length of these elements 2,3 produced by deforming forces will result in changes in the electrical signals which can be detected at 13. Application to hydrophones is mentioned. <IMAGE>
