Abstract: A wireless access point may be in the form of a femtocell basestation in a cellular network. In order to establish a connection into the cellular network, an identity token is required for authorisation. A remote service, accessible over a Wide Area Network such as the internet, can register with the access point. When a connected user attempts to connect to the remote service, information derived from the identity token is inserted into the data traffic. Where the identity token identifies the access point, the remote service can return location-specific information. Where the identity token identifies the connected user, the remote service can return subscriber-specific information. The access point can insert information derived directly from the identity token, or it can use the identity token to access a service identity registry, and can then insert the service identity into the data traffic.

Abstract: 843,123. Fluid-pressure servomotor-control systems; valves. NORMALAIR Ltd. Feb. 10, 1958 [March 28, 1957], No. 10117/57. Class 135. An outflow valve for a pressurized cabin comprises a main valve 13 actuated in response to pressure changes on either side of the valve, pressure on one side being controlled by a secondary valve 28 actuated by means e.g. diaphragm 27 responsive to a pressure signal received remote from the outflow valve, pressure relief valve means 39 for relieving pressure on said one side of the main valve, and automatic' outflow control means formed by a spring- loaded baffle 16, subjected on one side to atmospheric pressure and on the other to enclosure pressure via housing ports 22, 23. A pressure controller 1 detects atmospheric pressure via pipe 9 and communicates a signal pressure via pipe 8 to one side of a spring-loaded diaphragm 27 connected to a valve 28 controlling an atmospheric vent from said one side of the main valve i.e. chamber 42 open to cabin pressure via restriction 41, the other side of diaphragm 27 being exposed to the pressure chamber 42. The main valve 13 is carried by a diaphragm 15 and positioned by cabin pressure acting via openings 22 beneath the diaphragm and the control pressure in chamber 42 acting above the diaphragm. Should pressure in chamber 42 rise unduly a diaphragm 35 is raised until the relief valve is opened by its stem contacting the housing 12. An outlet baffle 16 is connected by a diaphragm 17 to the walls of the cup forming the main valve and is acted on its upper side by cabin pressure and on its lower side by atmospheric pressure, the baffle-restricting outflow at high altitudes should the main valve fail. The signal pressure in pipe 8 is communicated by pipe 10 through a plurality of outflow valves. Specification 843,124 is referred to.

Title: Improvements relating to fluid pressure braking apparatus
IPC: B60T15/54
Filed: 1920-04-12
Abstract: 165,560. Westinghouse Brake Co., Ltd., and Leech, K. H. April 12, 1920. Fluid-pressure.-In graduated release for use with triple valves, of the kind in which the release valve is closed by a spring opposed by the train-pipe and brake-cylinder pressures, the train-pipe pressure acts upon the valve through a second spring which is stressed to an extent dependent upon the difference between the trainpipe and brake-cylinder pressures. The brakecylinder exhaust port of the triple valve is connected at 3 so that with this valve in the release position the brake-cylinder pressure acts upon the release valve 6 and also upon a piston 12 which is subject on its other side to the pressure in the train-pipe connected at 2. The effective area of the valve 6 which is subject to the brake-cylinder pressure is greater than that of the piston 12. A spring 11 is interposed between the piston 12 and the stem 5 of the valve 6. An increase of train-pipe pressure after an application of the brakes by increasing the stress of the spring 11 unseats the valve 6 and the brake-cylinder air exhausts through the passages 10 until the pressure in the brake cylinder has fallen sufficiently to permit the spring 8 to re-close ths valve 6. The piston 12 abuts against a projection 14 on the valve stem 5 to unseat the valve 6 to a substantial extent in the final stage of the release operation.

Abstract: 418,984. Reinforcing tennis racket frames. NASH, R. J., Nelson Passage, High Street, Birmingham. April 5, 1933, No. 10166. [Class 145 (i).] A racket frame 2, 3, Fig. 5, is secured by clamps 6 to the face of a bracket 7 mounted in the bifurcated end 9 of a lever 10 pivoted at 11 on a base 12 ; the bracket is then swung past a rotary cutter 14 to make an arcuate cut in the face of the racket; the operation is then repeated on the other face of the racket, which is turned over on the bracket 7. Plywood 1<a>, Fig. 6, is bedded into the acts on both faces of the racket by blocks 17, which may be rubber faced, carried by a clamp 18. The inlay is trimmed off flush with the face of the racket handle, producing the effect shown in Fig. 1. Alternatively the inlay may be solid and cut to the required shape before insertion. The thickest part of the inlay occurs at the point where the material of the head sweeps out of the side of the handle, that is, where the greatest reinforcement is required. The method may be applied to the repairing of frames, the cuts being made across the point of fracture or weakening. The method may be used in conjunction with the methods described in Specifications 418,982, 418,983, and 418,985.

Title: Gas-lubricated bearing
Inventor: SIXSMITH HERBERT
IPC: F16C32/06
Filed: 1957-03-28
Abstract: 880,997. Fluid bearings. NATIONAL RESEARCH DEVELOPMENT CORPORATION. March 28, 1958 [March 28, 1957], No. 10206/57. Class 12 (1). In a rectilinear-motion gas bearing comprising a body 1 having a plane lower surface separated from a pad 2 by a film of gas disposed in a clearance space h, gas under pressure is supplied through a central hole 4 and flows through the clearance space into an annular cavity 3, which communicates with the clearance space to form a pressure zone, from which it escapes through a restricted passage 20. Some gas also escapes through the clearance between the periphery of the pad 2 and the surface of the body 1. The arrangement of the cavity, restricted passage, and pressure zone is such that any periodic oscillation of the body 1 and pad 2 relative to each other sets up corresponding periodic gas pressure alternations in the pressure zone having a phase such that pressure maxima occur when the members are moving towards one another to decrease the clearance space. In a modification, gas flows into a cavity 3 through the clearance between the body 1 and annular surrounding margin of the cavity. In a further modification, gas is supplied through a restricted inlet 20, Fig. 8, to a cavity 3 communicating with the clearance space h through a hole 4. The space h is enlarged, as compared with the previous embodiments, which has the effect that the body 1 is attracted towards the pad 2 when gas under pressure is forced through the hole 4. In another embodiment, gas is supplied to a cavity 3, Fig. 10, through a pneumatic amplifier comprising a spring-pressed diaphragm 5, having a central aperture 10, which cooperates with a valve seating 6. The surfaces of the supported member and supporting pads need not necessarily be flat. Specification 797,528 is referred to.
