Title: Improvements in or relating to a ventilation damper arrangement
Inventor: HOBDAY TERENCE VICTOR
IPC: F24F13/15
Filed: 1986-04-09
Abstract: A ventilation duct contains a damper adapted to close the duct. An inspection cover is mounted in the duct adjacent the damper to permit inspection of the damper. A position setting mechanism for the damper is mounted within the inspection cover so that the entire setting mechanism may be removed from the damper when the inspection cover is removed. This enables the cover, including the position setting mechanism, to be factory manufactured for easy installation on site. The setting mechanism includes an over centre latching trigger mechanism for a locking lever 18 fixing the position of the actuating shaft 8. The actuating linkage incorporates a fusable link 11 (Fig. 2). <IMAGE>

Title: Diverless flowline connection and pull-in system
Inventor: HED JON EVERETT
IPC: F16L1/26
Filed: 1986-05-22
Abstract: Apparatus includes means for positioning termination receptacles TR subsea with inboard flowline terminations I therein. A pull-in tool PT is lowered and latched onto receptacles TR and utilizes wire line cables (394) attached to the outboard flowline terminations (O) lying on the subsea floor to pull terminations (O) into funnels (256) in tool (PT) where they are latched, thereby eliminating further need for the cables. Thereafter, funnels (256) are hydraulically moved toward terminations (O) where an articulated bull nose (262), funnel cam (290) and alignment plates (264/266) accomplish vertical, horizontal and axial orientation leaving only horizontal translation of terminations (O) into receptacles (TR). After terminations (O) are hydraulically horizontally translated and latched in receptacles TR, tool (PT) is retrieved and a make up tool MT (Fig. 16, not shown) is lowered and locked onto receptacles TR where tool MT hydraulically removes covers (150/380) from the terminations (I and O) and places seal rings (500) between them. The tool (MT) is then hydraulically actuated to make the final connections. Thereafter, tool (MT) is removed. <IMAGE>

Title: Magnetic catch
Inventor: MORITA TAMAO
IPC: H01F7/02
Filed: 1986-12-29
Abstract: The catch comprises a first part A having a permanent magnet 1 with a hole H therethrough and a one pole face a, and a second part B ferromagnetic backing plate 2 against in the form of a second ferromagnetic plate 3 with a projection 3a locatable in the hole H. The hole terminates in an opening which is greater in one dimension than in another perpendicular thereto. This opening may be defined by the magnet having a uniform hole of this shape, or by a casing member covering at least the pole face b. The shape of the hole allows the catch to be released by pivoting the parts apart about a point on the edge of the magnet in line with the greater dimension of the opening, whilst preventing inadvertent tilting in any other direction. The catch may be used on handbags, jewellery or as a support for a hook. <IMAGE>
Patent GB-864859-A (GB)
Abstract: 864,859. Inducing draught. FEARNLEY, G. C., and BROWN, R. W. Jan. 21, 1960, No. 2165/60. Class 126.

Patent GB-866790-A (GB)
Abstract: 866,790. Solid fuel stoves. FONDERIE DU MOULINET. Aug. 7, 1957 [May 18, 1957], No. 24856/57. Class 126. A stove for continuous firing with a coal of high volatile content comprises a downwardly-diverging fuel hopper 2, Fig. 1, an ash box 3 removable through a door and a bottom grate 7, Fig. 4, formed of two elements which pivot on axles 7a, 7b coupled at 7c. Primary air, indicated at B, enters through the grate 7 and passes through the fuel to a zone 16 constituting a flame chamber immediately behind a mica window 6. Additional air, indicated at C, enters the flame chamber through the front portion of the grate, thence behind a front grate 7d in order to ignite volatile materials brought thereto by a third air current indicated at E. The third current enters through an aperture 15 into the top of the hopper above the fuel from a passage between the rear wall of the hopper and the stove body where it is heated by a recuperator 8 and sweeps the volatile materials down through the hopper to the flame chamber. A bar 17 is mounted in the flame chamber to increase the combustion by creating a turbulence before the combustion products enter side flues leading to the recuperator. All the air currents are controlled by a valve 14 at the rear of the stove and a plug (not shown) may close the aperture 15 to cut off the third air current when necessary.

Patent GB-2210438-A (GB)
Title: Improvements in solenoid-operated fluid-flow control valve assemblies
Inventor: MORTIMER IVAN
IPC: B60T13/68
Filed: 1987-10-02
Abstract: A solenoid-operated flow control valve comprises an armature (6) which is spring urged in one direction normally to close one of two axially spaced valves (11, 12) in a body (1), and a single solenoid coil (13) which, when energised, urges the armature (6) in the opposite direction to open the valve (12) and close the valve (11). The two valves (11, 12) are in open communication only during the transitional movement of the armature (6) between extreme positions. Thus a finely controlled flow rate through the valve can be achieved by pulsing an energising current applied to the coil to cause oscillation of armature (6) in the body (1) between the extreme positions. This is of advantage when releasing fluid from, or applying fluid to, a brake in an hydraulic anti-lock braking system. <IMAGE>

Abstract: A hand-guided machine tool equipped with a support plate (2) has guide bars (15 and 16) of a parallel stop (40) guided in guide ways (3 and 4) in the support plate (2). The guide bars (15 and 16) are bent away from the main body of the parallel stop (40) and are provided with stiffening corrugations (41, Fig. 1). The guideways (3 and 4) are formed by upper and lower bridges (e.g. 5). The guideways (3 and 4) are transversely interconnected by a guide passage (9) which is formed by upper bridges (10) and lower bridges (11). The guide passage accommodates a pressure piece (12) and, in a widened portion (13), a cam plate (14). The guide bars (15 and 16) are simultaneously clamped, or this clamping action is released, by turning the cam plate (14). The tool (22) may be a circular saw, a milling disc, or a grinding disc. A handle (20) is provided. The depth of cut is adjusted by turning a screw (38). A helical spring (35) urges the tool (22) towards a retracted position away from the workpiece. The tool (22) can he adjusted in axial position by turning a knob (29). <IMAGE>

Title: Integratable transceiver
Inventor: BATES ROBERT NEIL
IPC: G01S7/03
Filed: 1989-01-11
Abstract: An integratable transceiver comprises a Gunn diode harmonic oscillator whose output is coupled by way of a square waveguide section (14) and a circular polariser (48), interfacing with the square waveguide section (14), to an antenna. A return signal has its E field rotated through 90 degrees by the circular polariser (48) as it propagates into the square waveguide section. A receiver front end comprises a sub-harmonic mixer which has a first probe (50) projecting into the square waveguide for coupling-out the return signal and a second probe (56) for providing a local oscillator signal. The sub-harmonic mixer comprises a pair of anti-parallel connected diodes and the connection of the first probe is by way of suspended stripline. The described integratable transceiver can be used in FMCW radars and avoids the need for a circulator when using a single antenna. The Gunn diode is mounted in a harmonic oscillator cavity (14') and the local oscillator signal is produced by a parallel mounted fundamental cavity 32. The fundamental cavity (32) acts as a locking control on the harmonic cavity (14') via a coupling probe (30). <IMAGE>
