Title: Slip-controlled brake system for road vehicles
Inventor: FENNEL HELMUT
IPC: B60T8/34
Filed: 1985-04-10
Abstract: A slip-controlled brake system for road vehicles, for example, in which one front wheel (VR, VL) and one rear wheel (HR, HL) at a time are connected to a common braking pressure control channel the braking pressure variation in the two braking pressure control channels is influenced in dependence on predetermined selection criteria such as "select-low" and "select-high" criteria. A cornering identification circuit (20') is provided which each time adds up the slip values (SVL, SHL, SVR, SHR) of the two wheels of one side of the vehicle and compares them with the slip value sum (SL, SR) of the wheels of the other side of the vehicle. As soon as the difference of the slip value sums of the two sides of the vehicle exceeds a limit value, the selection criteria and, hence, the braking pressure variation are temporarily changed. By means of the cornering identification circuit, which can be employed in other slip-controlled brake systems, and operated in the described manner, it is possible to generate information about the driving direction, i.e. about straight-onward driving or cornering, and to logically process it within the scope of brake slip control or traction slip control, irrespectively of the number of existing braking pressure control channels. <IMAGE>

Title: Adjustable friction hinge
Inventor: BISBING ROBERT H
IPC: E05D11/08
Filed: 1985-04-24
Abstract: The hinge comprises first and second components (10, 20, 30) having knuckles (12, 22, 32) hinged together by a hinge pin (50) so that the first component can be rotated relative to the second components. Washers (41, 42) are interposed between the adjacent, relatively rotatable faces of the knuckles. The hinge pin has a head (53) at one end and a screw portion (51) at the other for engaging with respective endmost knuckles to consolidate the hinge. The hinge pin can be rotated to vary the forces of consolidation and the frictional resistance to operation of the hinge. The washers are made of a different plastics material from the knuckles and is chosen to provide substantially constant frictional resistance to relative movement of the knuckles. The hinge pin is made of the same material as the knuckles. <IMAGE>

Title: Climbing device for mountaineers
Inventor: PRAUSE BERNT
IPC: A63B29/02
Filed: 1985-05-03
Abstract: The climbing device for mountaineers serves for the releasable clamping in a rock crevice, rock fissure or the like. It consists of a support rod (2) and of a pivot pin (4) located at one of its ends (3) with a clamping plate (1) arranged eccentrically thereon, which is able to swing about the pivot pin axis (15). The clamping plate (1) can be forced in the direction of its clamping position and moved in the opposite direction by way of an actuating member (5) guided on the support rod (2). In order to ensure the possibility of using the climbing device even under the most unfavourable conditions and in order to reduce the load on the pivot pin (4) to a minimum, it is provided to give each clamping plate (1) opposite contact surfaces (21,22) on the end face, which are constructed as substantially identical curved sections. Each clamping plate (1) bears by two curved sections on the opposite walls (19) of a rock crevice and in its clamping position ensures a reliable hold, without the clamping forces acting on the pivot pin <IMAGE>

Title: Purification of gases
Inventor: GARRETT MICHAEL ERNEST
IPC: B01D53/04
Filed: 1985-05-17
Abstract: Apparatus for the production of substantially pure nitrogen (or noble gas other than helium) comprises a plant for the separation of nitrogen from air by pressure swing adsorption, a catalytic reactor for removing oxygen impurity by reaction with hydrogen, and a membrane separator for separating hydrogen and water vapour from the nitrogen to form a substantially pure product nitrogen stream. A part of the permeate gas from the membrane separator is recycled to the compressor of the plant whereby it is mixed with incoming air for separation. The need for precise control of the amount of hydrogen added to the impure nitrogen entering the catalytic reactor is obviated as excess hydrogen is removed from the nitrogen in the membrane separator.
Patent GB-2160941-A (GB)
Title: Emergency brake
Inventor: BARNARD ROBERT EDWARD BLAKE
IPC: B61H13/32
Filed: 1985-06-13
Abstract: A train emergency braking system provides a braking force proportional to the weight of the train and also takes account of variation (caused by wet, leaves, etc) in the coefficient of friction between brake pad and rail. A downward force, which is a fraction of the weight, is imposed on a framework between a brake pad at one end and a roller at the other (leading) end. Brake friction tends to drag the framework back against a spring until the spring force equals the braking force. A stable condition is thus achieved. A lever or ramp system may replace the spring arrangement. <IMAGE>

Title: Pellicle structure for transmission of mid ultraviolet light
Inventor: GORDON JOSEPH
IPC: G03F1/62
Filed: 1985-09-25
Abstract: A freely standing thin pellicle film of cellulose acetate butyrate is formed by spinning on a rotating substrate.

Title: Speech recognition
Inventor: BICKERTON IAN
IPC: G10L15/32
Filed: 1990-03-29
Abstract: Speech recognition is carried out by performing a first analysis of a speech signal using a Hidden Semi Markov Model and an asymmetric time warping algorithm 16, 17, 18. A second analysis is also performed using Multi-Layer Perceptron techniques in conjunction with a neural net 20. The first analysis is used by the second to indentify word boundaries. Where the first analysis provides an indication of the word spoken above a certain level of confidence, an output representative of the word spoken may be generated solely in response to the first analysis, the second analysis being utilised when the level of confidence falls. The output controls 4, a function of an aircraft and provides feedback, 3, to the speaker of the words spoken. <IMAGE>
