Patent GB-846879-A (GB)
Abstract: 846,879. Gyroscopic apparatus. ELECTRIC & MUSICAL INDUSTRIES Ltd. May 10, 1957 [Feb. 21, 1956], No. 5271/56. Class 97(3). [Also in Group XXXIII]. In a gyroscopic device comprising a rotatable system having a rotor 2 driven by a motor 5, wherein said system is mounted in a supporting structure comprising portions 8, 9 and 11 by being supported about a point G (its centre of gravity) on spherical surfaces 7, 10 permitting universal angular movement in the portions 8, 9 of said structure, the point G being fixed relative to the structure means are provided which tend to maintain said system and said supporting structure in the predemined angular relationship about said point shown in full lines in the drawing. The rotor 2 has a ball bearing 21 for supporting a member 16 which is connected by universal couplings 25, 26 to a shaft 18 and a shaft 19 slidable in a bush 27 on the portion 11. A spline 28 prevents shaft 19, and hence the member 16, from rotating relative to the supporting structure. The shaft 19 has a spring 20 tending to maintain shafts 18, and 19 in alignment with each other and with the axis of the rotatable system. The motor 5 is carried by the member 16 via arms 31, 32 which pass through slots 12, 13 in the structure portions 8, 9. The member 16 may comprise apparatus which is to be stabilised by the gyroscopic device or it may comprise a support for such apparatus. If the supporting structure moves, e.g. to the right, the movement will not be transmitted immediately to the member 16 since the inertia of the rotatable system prevents rapid angular movement of said system about the point G. The bush and shafts however move to positions 271, 191, 181, increasing the distance of the bush from a shaft 17 on member 16 thereby causing shaft 19 to slide in the bush 27 and compress spring 20 so that the latter exerts a force which is transmitted to the rotatable system causing precessional movement of the system about point G, which slowly returns the shaft 19 back to its original position in relation to bush 27, thereby restoring the original angular relationship between the rotatable system and the supporting structure.

Title: Hydraulic brake apparatus
Inventor: ZIRPS WILHELM
IPC: B60T11/18
Filed: 1985-01-04
Abstract: A hydraulic brake apparatus has two individually operable brake pedals (10, 15), which serve to modulate two traction vehicle brakes (14, 19) of a driven rear axle of a traction vehicle. A controlled check valve (23) is arranged between the brake master cylinder (12) operated by the first brake pedal (10), and a trailer brake valve (40). The second brake pedal (15) is operatively associated with the valve opening piston (32) of the valve (23). If the first brake pedal (10) alone is operated, then pressurised medium can flow only to the traction vehicle brake (19), because the valve (23) is closed. If the second brake pedal (15) alone is operated, then the valve (23) is opened. However, because the brake pedal (10) is not operated, no pressurised medium flows through the valve (23). If both brake pedals (10, 15) are operated simultaneously, then the trailer brake valve (40) is operated and the trailer brakes (48) come into operation. The brake apparatus is of simple and compact construction. <IMAGE>

Title: Apparatus for and method of production of a camshaft
Inventor: BARNETT MICHAEL FREDRICK
IPC: F01L1/047
Filed: 1985-03-27
Abstract: A composite camshaft is produced by slidably assembling a succession of individual cam elements 10 on a cylindrical common shaft 16. All of the cam elements are initially preassembled on a guide bar 14 and are then transferred successively on to the co-axially mounted shaft 16 which has adhesive applied thereto at a succession of predetermined axial positions. After each camshaft element has been located on the shaft 16, it is rotatably indexed to a predetermined angular orientation to receive the next camshaft element from the guide bar 14 at a next predetermined axial position at which adhesive has been applied. <IMAGE>

Title: Protective automatic eye shield
Inventor: PENNY DONALD EDGAR MICHAEL
IPC: A61F9/06
Filed: 1985-05-28
Abstract: An eye protective device for welding which allows the operator to achieve clear vision without having to push the headshield up and subsequently nod it down again to continue operation, has a web with transparent 15 and filter 16 areas. The web is wound between spools and is movable across the line of vision using a film transport system which can be operated automatically via a control box which also controls the welding plant. Alternatively the web transport is powered with self contained or portable cells and controlled manually by the operator. The invention maintains eye safety by having the splatter guard in place at all times, a transparent area of the web being brought into the line of vision to view the workpiece and removing the nodding procedure enhances the productivity. <IMAGE>

Title: A lubricant slinger for dynamoelectric machines
Inventor: UHEN RICHARD FREDERICK
IPC: H02K15/00
Filed: 1987-01-21
Abstract: A lubricant slinger mechanism for preventing the loss of oil or other lubricant which is pumped between the rotor shaft and bearing in an electric motor or other dynamoelectric machine. The slinger is mounted to the rotor shaft and mounted adjacent the end of the bearing out of which oil flows as it is pumped along the shaft from the reservoir. The slinger initially throws the oil radially outward against an inner oil well cover, and the provision of an impeller, such as a spiral vane on the outer peripheral surface of the slinger, imparts an axial component of velocity to the lubricant which impels it rearwardly toward the reservoir and prevents the migration of oil out of the forward end of the oil cover through which the rotor shaft extends. The slinger, in one form, includes an annular cup portion which overhangs the end of the bearing so that lubricant is thrown off the slinger at a point rearwardly of the end of the bearing. The slinger is preferably formed with an opening that is larger in diameter than the shaft and includes a tapered surface on one end so that as the brass rotor sleeve is inserted into it, it centers the slinger and enables the brass sleeve to be pressed therein by means of automatic assembly machinery.

Title: Electro-optical detection system
Inventor: SUTTON PHILIP
IPC: G01S7/493
Filed: 1989-05-11
Abstract: Spectrally separated signal and reference channels are selected to look at a field of view, to detect an object. The reference channel embedded in a partially transmitting medium is chosen such that transmission in the medium is low and the signal channel bandwidth is chosen such that transmission is high. By subtracting the two channels the effect of surface and other reflections is removed leaving an enhanced signal. A particular application is to the detection of objects underwater, making use of a remote control video camera 20 with zoom lens, when the signal channel is formed by merging a blue 23 and green 22 channel in such proportion as to optimise the transmission to the condition of the sea medium. The reference channel 21 is then a red channel. Ideally the channels should be close together so that reflection is similar in the signal and reference channels. A notch filter may be used to ensure that a spectral stopband exists between the signal and reference channels.

Title: Credit and bank cards
Inventor: BARNARD NIGEL ANDREW SIMON
IPC: G07F7/10
Filed: 1990-04-02
Abstract: A card security system comprises a card reader means, a card which includes an identification code capable of being read by said card reader means, and a module which includes a receiver means operably connected to a transmitter means. The transmitter means transmits a coded signal when the receiver means receives a suitable coded signal. In operation when the card is read by the card reader means, the card reader means transmits a coded signal to the receiver of the module. The module then transmits a coded identification signal to the card reader means which compares the coded identification signal with the identification code of the card to indicate whether the identification code and the coded identification signal correlate. The system may then allow a credit card transaction to be carried out depending on whether the code and signal correlate.
