Patent GB-652905-A (GB)
Abstract: 652,905. Chain railways. JENSEN, H. H. M. B. Aug. 19, 1948, No. 21881. Convention date, July 11, 1941. [Class 104 (ii)] A conveyer for bar material comprises a carriage 9 which is provided with means for gripping the material and is reciprocated upon a track by an endless driving chain 3 moving continuously in one direction, the driving engagement being provided by a T-headed pin 8 on the chain engaging within a transverse guide slot 10 in the carriage so as to slide therein when the carriage is at an end of the track, means being provided for automatically releasing the transported material at an unloading point. As shown, the conveyer is adapted to draw galvanized tubes from a galvanizing bath and has a track formed by inwardly directed flanges on a pair of parallel plates 1 inclined upwardly from the bath, with the endless chain 3 located between the track plates and passing around a guide roller 4 at each end of the track. The parallel longitudinal portions of the chain 3 are in a plane parallel with the plane of the track and pass around two intermediate rollers 5, 6 of which roller 5 is driven by a motor 7. The carriage 9 is provided with two pairs of rollers 11, 12 at each side to engage both faces of the flanges along the upper edges of the side plates 1, thereby preventing the carriage from tilting. The gripping device comprises a pivoted jaw or plate 14 carried on a support 16 at the end of a bar 15 which extends laterally from one side of the carriage the jaw being urged towards a fixed bar 13 by a spring 19 connected to an operating lever 18 extending rearwardly from the jaw 14. A lateral stop 22 at the unloading position engages the lever 18 to release the load. Brackets 23 projecting laterally from one of the rail plates 1 provide supports over which bars &c. slide during conveyance.

Title: Treating carbon fibre
IPC: D01F11/10
Filed: 1978-08-11
Abstract: Carbon fibre is subjected to a surface removal step (e.g. with nitric acid) followed by a surface deactivation step. The surface deactivation step comprises either removing at least some of the functional groups on the surface of the fibre (e.g. by heating in N2 at 530 DEG C) or rendering those functional groups incapable of forming a chemical bond with a resin matrix material e.g. by coating the fibre with polyethylene. When such treated fibres are incorporated in a resin matrix, the resultant composite material is provided with enhanced strength properties when compared with similar composite materials containing untreated carbon fibres.
Patent GB-2031503-A (GB)
Title: Electric lock circuit
IPC: G07C9/00
Filed: 1978-09-25
Abstract: An electrically-operated lock circuit has a coding and selector circuit that comprises a first set of switches V1-V3 to set up a desired code number by which the lock is released, and a second set of digit switches 50-59 for entering numbers. The coding and selector circuit supplies signals to a logic circuit (Fig. 1), realised in a particular embodiment by relays, which only releases the lock if the correct code number is entered. Any false number entered prevents the lock circuit from being released and the entry of a wrong number having the same number of digits as the code number operates an alarm circuit. The push-button switches can be realised with read switches.   <IMAGE>

Title: Instantaneous calendar device for timepieces
IPC: G04B19/253
Filed: 1979-02-27
Abstract: In a timepiece calender mechanism having a date ring 8 and day disc 12 and a spring storage device for rapid advance of the date ring by means of a projection 7 on the output member 6 of the storage device, the day disc is attached to a seven-lobed Geneva wheel 11 which is normally restrained by the output member 6 and holds a jumper 13, 14 in position to block the date ring.

Title: Improvements in or relating to optical fibres
IPC: C03B37/018
Filed: 1979-03-01
Abstract: In a graded optical fibre comprising a core 11 of transparent material having throughout its length a cladding 12 of another transparent material of a lower refractive index than that of the material of the core, the refractive index of the material of the core gradually decreases towards the outer surface of the core, and, at any transverse cross-section of the optical fibre, all refractive indices of substantially the same value lie on a contour 13 which is eccentrically positioned with respect to the central axis of the fibre. Preferably, each point on a contour 13 of refractive indices of the same value follows a helical path down the length of the fibre. The bandwidth and other transmission characteristics of an optical guide built up by connecting such graded optical fibres end-to-end can be closely controlled and predicted. <IMAGE>

Title: Heat Treatment Method
IPC: C21D3/04
Filed: 1979-11-21
Abstract: In order to decarburise ferrous metal without recourse to an exothermic generator, an inert gas (typically nitrogen), water and a liquid or vaporous compound of carbon, hydrogen and oxygen (typically methanol) are admitted to a working chamber of the heat treatment furnace in which the metal is situated. The decarburisation is preferably performed at 700 to 800 DEG C. The methanol and water react to form a non-oxidising, decarburising atmosphere at the decarburising temperature. The metal may be oxidised at a temperature below 600 DEG C in another chamber of the furnace, the atmosphere from the decarburising chamber being passed into the oxidising chamber.
