Patent GB-2201729-A (GB)
Title: Lockable window stay
Inventor: YATES ROBERT EDWARD
IPC: E05C17/22
Filed: 1987-01-23
Abstract: A window stay arrangement capable of being securely locked in an infinite number of window opening positions over the length of the stay 2 additionally offers improved security in the closed position. This relies on a cylinder (3) locked by screw 1 which whilst serving as a stay guide allows for both axial rotation and a vertical angle of the stay (2) determined by the width of the window opening, but in the locked position secures the stay (2) from any movement. In the window closed position of Fig. 2 an end of stay 2 is secured by insertion in anchor post 6. To open the window stay 2 as pivoted about cylinder 3 to the Fig 2/4 position then pushed outwards, stop 17 may be unscrewed to withdraw stay 2 from cylinder 3. <IMAGE>

Title: Rudder system for marine vessels
Inventor: CORLETT BRIAN JAMES
IPC: B63H25/38
Filed: 1987-03-26
Abstract: In a ship's steering and propulsion system, flanking rudders 10 are provided for steering the ship when going astern, which rudders have aftwards extensions 13. The rudders 10 are forward of a nozzle or duct 12 and the extension 13 on one rudder or the other closes up to the adjacent side of the nozzle nose 21 when the rudders are put over to obviate undesirable leakage around the nozzle nose at that side. The extensions 13 may be fixed or they may be articulated to turn to a lesser angle than the main blades of the rudders. Also provided is a linkage for turning the trailing edge flaps on the rudders to a lesser angle, or the leading edge flaps to a greater angle, than the angle of turn of the main rudder. <IMAGE>

Title: Railway sleeper spacing device
Inventor: CLARK ERNEST STEPHEN
IPC: E01B29/13
Filed: 1988-08-08
Abstract: A sleeper spacing device comprises a support beam 2 and 6 having travel slots 3 of increasing size and four slotted rack-bars 7 mounted alongside the support beam 2 and 6. The slots 8 of the rack-bars are co-incident with, and are in reverse proportion to the support slots 3. Shackles 4a carrying sleeper pick-up members 4b extend through both support beam and rack-bar slots 3 and 8 and are movable along the travel slots 3 to form a more spaced condition as the trailing edge of the co-incident rack-bar slot engages the shackle 4a. The eight shackle 4a from the ends of the support beam is stationary and although equispaced in the less spaced condition, it becomes too close to adjacent movable shackles 4a (and thus obsolete) when the two sets of six and seven shackles 4a on either side thereof are removed towards it by respective rack-bars 7. <IMAGE>

Patent GB-2236968-A (GB)
Title: Tool chuck with torque amplification
Inventor: NAKAMURA DAIJIRO
IPC: B23B31/173
Filed: 1990-06-15
Abstract: The chuck comprises a locking device 22 disposed between a chuck body 11 and chuck claws 12 slidable by screw feeding. The locking device presses and locks to the chuck body by a reaction force occurring when the chuck claws clamp a tool. The tool chuck further comprises torque amplification between the locking device 22 and a control ring 21 rotatably mounted on the chuck body 11. When the locking device 22 is locked to the chuck body 11, rotation of the control ring is reduced to output an amplified torque to a screw ring 15 which screw-feeds the chuck claws. The chuck claws are rapidly slidable until they clamp a tool inserted in position to realize a quick clamping action whereupon they are slidable with an increased torque, thereby holding the tool with a strong clamping force. Force amplification is by the control ring 21 being eccentric to the locking device 22 with intercoupling balls or gear teeth. <IMAGE>

Patent GB-2239268-A (GB)
Title: Dewatering press
Inventor: LEHTONEN JARMO
IPC: D21F3/02
Filed: 1990-12-19
Abstract: A press for dewatering a newly formed paper web comprises an extended nip between a roll (1) and the arcuate face of a press shoe 2, across which moves a slide band (7) carrying the web (6) sandwiched between two felts (4, 5) (Fig. 1). The band is impervious and is supported on the shoe 2 by a combination of hydrostatic and hydrodynamic forces induced by feeding pressurised lubricant to channels 13, 14, 15 which extend along the shoe axially of the roll. Between channels 14 and 15 an additional cavity, no more than 0.75 mms. deep, is formed with radius R', smaller than radius R of the shoe surface as a whole. This enables the band (7) to be supported mainly hydrodynamically at design speed but hydrostatically at lower speeds. <IMAGE>

Title: Worm and wheel reduction gear
Inventor: TSUTOMU AIHARA
IPC: F16H1/16
Filed: 1991-06-12
Abstract: To facilitate assembly, a lower case pan 61 has a semicylindrical recess 63 which rotatably receives a worm 66 meshed with a worm wheel 67, and an upper case part 62 is mounted on the lower part 61 to close the recess 63.

Title: Fuselage of a model airplane
Inventor: WAGENER CLAUS
IPC: A63H27/00
Filed: 1991-07-16
Abstract: The invention discloses a fuselage which is subdivided into a fuselage lower part 1 and a shell-shaped upper fuselage portion 3, where the upper fuselage portion 3 is provided with windows arranged in rows 12, 13, the windows being formed by inserted pieces 8, as shown in Figures 1 and 4, with the fuselage moulded around them, the windows being formed on an integral insert part 7. It is desirable that, on the one hand, the upper fuselage portion including the injection-moulded window pieces be of simpler construction and, on the other hand, should have a continuous external fuselage surface extending continuously without any conspicuous joint line down to the joint with the fuselage lower part. This is accomplished in that the upper fuselage portion 3 is of single-piece construction down to the joint 2 to the fuselage lower part 1, with the windows being surrounded by said upper fuselage portion, and in that the elongated insert part 7 of shell-shaped construction continuously lines the upper fuselage portion piece 3 on the inside. The simplified single-piece construction of the upper fuselage portion provided with windows is achieved by the use of said insert part which is conveniently made by injection moulding. <IMAGE>

Patent GB-2262190-A (GB)
Title: Electrical apparatus enclosure
Inventor: COPPING STUART FRANK
IPC: H05K7/20
Filed: 1991-12-04
Abstract: An electrical apparatus enclosure 2 is provided with an outer casing 4 and an inner casing 6 for housing electrical equipment. Air is recirculated from the interior of the inner casing 6 through an air gap between the inner casing 6 and the outer casing 4 and back to the interior of the inner casing 6. The recirculation of air reduces the temperature difference between the walls of the inner casing 6 and the air within the inner casing 6. Condensation that forms on the inner face of the outer casing 4 leaves through drain holes 28 at the base of the inner casing 4. A roof chamber 12 is separated from the inner casing 6 by a baffle. Some of the air leaving the inner casing 6 through outlet openings 20 passes into the roof chamber 12 and is exhausted through exhaust openings 32 so as to remove heat from the enclosure. The air may be forced to recirculate by driven fans 16 which are provided with air filters. The pressure of the air within the inner casing 6 is maintained above that of the air in the air gap between the inner casing 6 and the outer casing 4. <IMAGE>

Title: Interference cancelling a radio transceiver
Inventor: SCHWARTZMAN ZALMAN
IPC: H04B1/50
Filed: 1992-05-16
Abstract: A radio transceiver has a receiver part (13, 14, 15, 16) using an injection frequency e.g. 806 MHz equal to the transmit frequency of a corresponding transmitter part, the latter including a modulator (10), synthesizer (11) and power amplifier (12), and modulates the injection frequency with an information signal when the power amplifier (12) is in an off state and the transceiver should not be transmitting, and if a signal is received from a radio infrastructure system, e.g. a base station, in response to the information signal, this indicates interference at a base site due to leakage from the injection frequency elements of the transceiver. Appropriate action is taken at the transceiver to stop the interference e.g. shutting off the radio for a certain period. The transceiver is used in radio trunking systems having a common control channel. <IMAGE>
