Title: Improvements in or relating to one-way engaging device
IPC: F16D41/07
Filed: 1951-12-19
Abstract: 706,947. One-way brakes. BORG-WARNER CORPORATION. Dec. 19, 1951 [Dec. 22, 1950], No. 29729/51. Class 103(1) [Also in Group XXIV] Sprags 24, which tilt about centres 29, 30 into and out of wedging positions between cylindrical inner and outer races 18, 21 of a one-way clutch or detent, are spaced and resiliently urged into the wedging position by a cage 31 formed of a single sheet metal strip or tube having openings 34 to receive the sprags, and tabs 35 in the openings which press inwards on shoulders 27 or grooves in one side of the sprags. As shown the strip 31 is of relatively thick (0.025-0.030 inch) spring steel, phosphor-bronze or beryllium-copper, in which the openings 34 are punched whilst flat so that when subsequently the strip is bent to permanent cylindrical form, the tabs 35 project outwards. Staggered shoulders 28, or narrower grooves in the opposite sides of the sprags retain the latter in the openings as a sub-assembly. In Figs. 4-7 (not shown), the cage is of considerably thinner strip e.g. clockspring or cold rolled stainless steel (0.007-0.009 inch thick) or beryllium copper (0.012-0.015 inch thick) and does not take a permanent set when bent to cylindrical form. The side walls flex as well as the tabs to apply pressure to the sprags, and the overlapped ends of the strip press resiliently on each other. The sprag sides have staggered grooves and the tabs lever the sprags about the opposite groove with with an increased lever-arm in comparison with that given, as in Fig. 2, by a fulcrum on the inner race. In Figs. 8 and 9, (not shown), a similar thin cage has axial corrugations for circumferential resilience, in which case the cage may be put in longitudinal tension or compression so that the pressure of the sprags on one race may exceed that on the other to reduce rubbing wear on the relatively rotating race during overrun. The openings at the two ends of the cage are both sprung over the same sprag to retain the sprags and cage as a sub-assembly. In Figs. 10 and 11 (not shown), the tabs 35 are given an initial inward set, to increase their pressure on the sprags. The cage and sprags may be assembled for rotation in either direction.

Title: Improvements in or relating to transporters
Inventor: FLURSCHEIM CEDRIC HARALD
IPC: B62D53/06
Filed: 1963-07-26
Abstract: 1,020,973. Multi-wheel transporter suspension; railway vehicle undercarriages. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. June 26, 1964 [July 26, 1963], No. 29759/63. Headings B7D and B7L. Part of the weight of a transporter having steerable bogies 9 and a load 3 is supported by a multiplicity of wheels 33, 49 mounted on flexible membranes forming the lower boundaries of pressure vessels 21, 47 which are pressurized to support the weight or evacuated to lift the wheels from a road or rail surface. The wheels are mounted on brackets 29 rigidly or pivotally secured to a membrane 23 which may extend in one piece across the vehicle. Alternatively separate membranes are provided on the two sides of the vehicle to permit the use of different pressures on the two sides to maintain the load horizontal on a cambered surface. Air chambers 19 are provided in the longitudinal members 15 of the transporter connected by passages 25 to the adjacent bellows. In an alternative (Fig. 7, not shown) a bellows is mounted within the member 15 which has an open bottom to permit retraction of the wheels 33 from sight. The arms 39 connected to the air receivers 45 are pivotable through 90 degrees by jacks 43 to lift the wheels 49 from the ground. As in Fig. 8 (not shown) the wheels may be mounted on arms 91 pivoted to member 15 and bearing on pad 95 secured to the membrane 23.

Title: Method and apparatus for regulating the quantity of air contained in the air cushion of a pneumatic spring, in particular for motor road vehicles
IPC: G05D16/18
Filed: 1958-09-17
Abstract: 847,324. Adjusting body height; pneumatic springs. KRUPP MOTOREN-UND KRAFTWAGENFABRIKEN G.m.b.H., F. Sept. 17, 1958 [Sept. 18, 1957], No. 29763/58. Classes 108(2) and 108(3). An air spring 2 has means for adjusting the distance between the sprung and unsprung portions of a vehicle. An elastic rubber packing 28 is fixed to both the parts 6 and 7. A space 9 is filled with fluid. A control piston 11 is slidable in a control cylinder 10. The space 9 is connected by a restricted passage 13 with an upper chamber 14 of the control cylinder 10. A passage 15 is connected to a source of compressed air, and a passage 17 communicates with the atmosphere. In operation the load supported by the spring is transmitted from a vehicle frame 1 and a member 8 to a pressure piece 7 and thence to the fluid in the space 9. This force is transmitted to the base plate 4 and acts on the spring constituted by the enclosed air cushion. When the load on the vehicle frame increases the pressure in the space 9 increases more than the pressure in the air cushion in the elastic bag 2, consequently the piston 11 moves down in the cylinder 10. This movement connects the channel 15 to the air cushion in the bag 2 through a T-shaped channel 18 with the result that air flows into the bag until the pressures in the air cushion and in the space 9 are equalised. If the load on the vehicle decreases the piston 11 moves upwards and allows air to escape to the atmosphere through the passage 17. The fluid in the space 9 may be under an initial pressure, this may be adjusted through a valve 30. The bottom of the control piston 11 may be stepped to form an annular space 23 as shown, or may be flat like the top of the piston. If the bottom of the piston is flat, passages 24, 25 and 26 are omitted. The annular space 23 is normally connected to the interior of the bag 2 via the passage 26, a valve 27 and the passage 25. When it is desired to alter the pressure in the annular space 23 the valve 27 is closed and a valve 29 is opened. This connects the space 23 to a supply of air under pressure. Thus the bag 2 may be elongated to its maximum extent and the vehicle frame 1 held in its highest position. Alternatively the bag 2 may be allowed to collapse.

Title: Improvements in or relating to electric relays employing magnetic contacts in sealed protective-tubes
IPC: H01H51/28
Filed: 1958-09-18
Abstract: 842,960. Electromagnetic relays. SIEMENS & HALSKE A.G. Sept. 18, 1958 [Sept. 20, 1957], No. 29937/58. Class 38 (5). The influence of a permanent magnet on magnetic contact springs in a sealed tube is varied by the current passing through a magnetic conductor. In Fig. 1, the contacts F1, F2 normally receive insufficient flux from magnet D to close them, but when a current is passed through the magnetic conductor strip N, causing an increase in its reluctance with respect to the field of the magnet D, the flux through the springs increases to cause their engagement. In Fig. 2 (not shown), the magnetic shunt N is placed between the magnet and the tube. In Fig. 3 the magnetic shunt consists of a wire loop W extending longitudinally of the tube and arranged outside (as shown) or inside the magnet D. This arrangement requires less current for operation. In Fig. 4 the magnetic strip or wire loop V completes the magnetic circuit between one pole of the magnet D and the contact spring F1 to maintain the contacts normally closed.

Title: Improved nuclear energy reactor structure
IPC: G21C1/00
Filed: 1958-09-22
Abstract: 866,037. Nuclear reactors. McALPINE & SONS Ltd., Sir R, and HAY, J. D. Sept. 11, 1959 [Sept. 22, 1958], No. 30271/58. Class 39(4). In a nuclear power plant the heat exchangers or boilers are located in a space between primary and secondary biological shielding walls surrounding the closed reactor space. In Fig. 1 concentric cylindrical concrete walls 1, 2 are erected on a concrete raft 3, the inner wall 1 enclosing a central chamber containing the reactor core and heat exchangers 15 being positioned in the annular space between the two walls. Pumps or blowers 14 allow coolant to be circulated from a header 9 below the central chamber through the reactor core, into the annular space between the two walls, and past the heat exchangers back to the pumps 14. The annular space may be subdivided by radial partitions (Fig. 2, not shown) so that individual heat exchangers 15 may be removed for servicing through manholes 27 whilst the remaining sets of heat exchangers remain in operation; one or more of the spaces may be left without heat exchangers and used as fuel disposal chambers or to provide maintenance facilities. The inner cylinder 1 may be of normal reinforced concrete or of prestressed concrete; the outer cylinder 2 is of pre-stressed concrete to withstand the full pressure in the structure and the annular space between the two is lined with insulation 17 to reduce temperature stresses and with a thin steel liner 18 to provide gas tightness. The thickness of the two concrete walls 1, 2 is selected to provide the required biological shielding. The roof and floor of the structure are restrained horizontally by pre-stressing around the outer ring and vertically by the use of pre-stressed rods or wires. In a modified structure, Fig. 5, which is built in a hole in the ground or in rock the outer concrete wall 2 may be thinner and of normal concrete since the surrounding ground or rock takes the outward pressure and provides biological shielding. The hole in the ground or rock may be lined with a thin steel liner 24 to provide gas tightness and the ground or rock surrounding the hole may be grouted. The pumps or blowers 14 are mounted above the roof in this construction.

Title: Improvements in silencers for jet nozzles
Inventor: CARRIERE PIERRE PASCAL AUGUSTE
IPC: F02K1/38
Filed: 1966-07-07
Abstract: 1,106,856. Jet propulsion nozzles - noise suppressing. SOCI•T• NATIONALE D'ETUDE ET DE CONSTRUCTION DE MOTEURS D'AVIATION. July 7, 1966 [July 28, 1965], No. 30659/66. Heading F1J. The invention relates to a jet propulsion nozzle assembly having means which are effective to silence the nozzle, the silencer comprising a plurality of tubular members through which ambient air may flow and which are adapted to project into the jet stream discharged by the nozzle. Each tubular member is acted on by a force tending to urge the member radially inwardly into the jet stream, and each member has at least one aerodynamic lift member connected thereto and adapted to co-operate with the jet stream so as to apply to the member a force acting radially outwardly, so that a portion of the tubular member projects into the jet stream to a substantially constant extent. In the embodiment shown in Fig. 2 the silencing device is similar to that of co-pending Specification 1, 106, 356 and comprises a series of tubular members 17 disposed round the jet stream downstream of the nozzle. Each tubular member 17 is movable between a retracted position, Fig. 1, and an operative position as shown in Fig. 2 in which ambient air flowing in the passage 4 is caused to flow inwardly through the member 17 into the jet stream. The tubular elements are mounted for movement about an offset axis 6 and are movable by linkage 12, 12a and 11. Each element 17 is mounted within an outer casing 18 and is urged radially inwardly by means of a spring 20 acting between the closed end 18b of the casing and a flange 21 on the tubular member. Each tubular member has an aerofoil member 19 secured thereto, the member 19 in operation producing lift so that the tubular member 17 is urged radially outwardly and thus takes up a position in which the opposing forces are balanced. In a further embodiment Fig. 5 (not shown), each tubular member 16 is moved between its retracted and operative positions by means of a pneumatic jack acting through a rack and pinion. The lift produced by the aerofoil member tends to move the tubular member outwardly against the opposing force of the pneumatic jack.
