Title: Novel silyl reagents and their preparation
Inventor: SHEPHERD ROBIN GERALD
IPC: C07F7/10
Filed: 1984-07-31
Abstract: The invention provides novel silyl reagents of formula IIIA  R<b>R<c>R<d>SiNCY wherein R<b> is a branched chain alkyl, cycloalkyl, aryl or branched chain aralkyl and R<c> and R<d> are selected from alkyl, cycloalkyl, aralkyl or aryl with the proviso that R<c> and R<d> are not the same radical as R<b>, and Y is oxygen or sulphur. A further novel compound tri-isopropylsilyl isothiocyanate is also included. These silyl reagents are useful in preparing tetrahydroquinoline 8-nitriles, amides and thioamides as described in Serial No. 2122992A.
Patent GB-2150651-A (GB)
Title: Face seal incorporating fluid pressure pump
Inventor: JANZEN DIETER
IPC: F16J15/00
Filed: 1984-12-03
Abstract: A slide ring seal arrangement with internal pump (18, 19, 20, 24) is designed as a confining medium seal, in which the pump is designed as a displacement pump and the chamber adjoining the slide ring seal (13, 14, 2) and receiving the confining medium under pressure is connected to a fluid discharge channel (28) which contains a flow resistance element (29), in particular a pressure limiting valve, which can be adjusted above the pressure to be sealed off. On the side of the pump turned away from the slide ring seal, a low pressure develops, which allows the arrangement to be closed off on this side by means of a more simple seal (17). The use of this arrangement is advantageous in particular in conjunction with the sealing off of shafts of centrifugal pumps, the pressure of which rises more slowly at low speed than that of the pump contained in the seal arrangement.   <IMAGE>

Title: Coordinate measuring instrument
Inventor: HANAOKA HIROSHI
IPC: G01D5/347
Filed: 1985-01-23
Abstract: The instrument incorporates for each coordinate direction, relatively movable portions A and B and an optical type displacement detecting device 10 for measuring the magnitude of the movement between the portions. Each device 10 includes a main scale 11 having a grating or fringes 15 formed by reflecting portions 15A and non-reflecting portions 15B arranged alternately in a row, an index scale 12 having a grating or fringes 16 formed by light transmitting portions 16A and non-light transmitting portions 16B also arranged alternately in a row, a light emitting element 17 for illuminating the index scale 12 and the main scale 11, and a light receiving element which receives light reflected by the main scale through the index scale and emits an electric signal corresponding to the magnitude of a relative displacement between the scales. The main scale is provided with an optical disturbance preventing layer 22 which either absorbs light transmitted through the non- reflecting portions of the main scale to prevent the light being reflected to the index scale or makes the light which is transmitted through the non-reflecting portions of the main scale on to the index scale, of pre-determined properties. The layer 22 may be sandwiched between the main scale 11, which is of glass and another glass strip 21. <IMAGE>

Title: Dust extraction apparatus for warp beam winder
IPC: D03J1/00
Filed: 1985-07-10
Abstract: Dust extraction apparatus for a warp beam winder 1 comprises a deflector 10 connected by ducting 13, 14 and 15 to a rotary fan 16 and an outlet duct 20. In operation, when yarn is wound at high velocity onto a warp beam 4, the dust and fly etc. liberated is deflected by the deflector 10 into the ducting 13, 14 and 15 and removed by the outlet duct 20 to a filtering system. The deflector 10 is movable to allow access by an operator of the winder 1 to repair broken threads of yarn etc. The rear wall (10b) of the deflector may be transparent. Instead of the side walls 2 of the winder 1 being shaped aerodynamically (as shown) they may be rectangular (Fig. 4) and have a preferably curved deflector positioned therebetween. <IMAGE>

Title: Handles for wrapped packages
Inventor: COLLINS BRIAN DAVY
IPC: B65B61/14
Filed: 1985-08-02
Abstract: An article (2) is wrapped in three plastics films (1, 4, 5) which are secured together at or near the bottom of the article by heat sealing using heat sealing jaws (9 and 13). The films (1, 4, 5) are then conformed to the shape of the article (2) by e.g. heat shrinking using hot air blower (16). One of the films (5) has different properties from the others and conforms differently so that it forms a handle for the wrapping. Strength of attachment of the handle is achieved by the combined effect of the heat seal (3) and the "tack" of the plastics films (4, 5) along the sides of the article. Alternatively, the films may be conformed by stretch-wrapping, film 5 being under lesser tension in the wrapped article to form a handle. <IMAGE>

Patent GB-2169691-A (GB)
Title: Control devices
Inventor: TRAYNER BRIAN THOMAS
IPC: F42C15/26
Filed: 1985-12-04
Abstract: A control device for use on board a projectile senses both linear and angular acceleration before initiating an output response. The device comprises an inertial mass 4 mounted for rotation relative to the projectile body, and latch means 17 for limiting such rotation until freed by linear acceleration, when the mass is free to rotate in response to the experienced angular acceleration to engage means for providing said output response. Latch 17 moves against the force of spring 19 to clear slots (15, 16) and release mass 4. Angular acceleration releases a detent 21 to allow a bush 11 to rotate relative to mass 4 but to become locked thereto when a hook 20 on the bush engages latch 17. The engagement breaks a shear- wire 8 holding the bush relative to a screw-threaded member (5),6, so that the mass 4 rotates, with the bush, relative to the member to make an electrical contact which generates the output response. <IMAGE>

Title: Builders straps with fasteners and anchors
Inventor: HOYLAND MICHAEL DOUGLAS
IPC: E04B1/38
Filed: 1986-12-10
Abstract: A two part strap assembly 10 has first and second strap parts 11 and 12 which are connected together by means of elongate slots 15 in the material of the strap. The strap ends 11 and 12 are overlapped (see Fig. 2) so that the borders 16 of the slots come into alignment and an apertured member 17 is driven through the slots.

Title: An electricity generating system
Inventor: ATTWOOD RICHARD
IPC: H02J7/34
Filed: 1987-05-08
Abstract: A main generator 12 powered by natural energy, such as the wind, is connected to energise a load and drive an auxiliary machine 16 as a motor during normal periods, a flywheel 18 then being driven by the machine 16. When the natural energy is interrupted or reduced, an electrically operated clutch 22 is engaged so that an internal combustion engine 24 is started by the flywheel 18 and thereafter drives the machine 16 as a generator to power the load, the flywheel 18 also being used to drive the machine 16 during the changeover of the drive of machine 16 from generator 12 to engine 24. Flywheel 18 may rotate in an evacuated chamber. In a modification, (Figure 2), the machine 16 motors the engine 24 at reduced speed via a speed reducer and a first unidirectional clutch during normal periods, and means responsive to a fall in output from generator 12 controls fuel supply or ignition to start the engine 24 which then drives the machine 16 through a second unidirectional clutch. <IMAGE>

Title: Vehicle hydraulic systems
Inventor: FARR GLYN PHILIP REGINALD
IPC: B60T13/565
Filed: 1987-12-17
Abstract: In a vehicle hydraulic clutch or braking system, with a remote booster 5 a master cylinder 63 (1; 51) Figs 1, 2 not shown is operative is response to an input from a pedal to produce a fluid pressure output force to operate at least one fluid pressure operated device 62 (4, 61), and the booster 5 augments the output force from the master cylinder 1. The master cylinder comprises a housing in which one or more pistons 52, 53(2) work to pressurise respective pressure spaces 54, 55(3), the housing also having a control chamber 64 (3; 54) and an hydraulic servo chamber 6 defined behind the pistons. The booster 5 is remote from the master cylinder and is operative to pressurise the servo chamber in response to pressurisation of the control chamber. This arrangement means that the hydraulic circuit containing the booster can be separate from the circuit or circuits containing the device, so that failure of one will not affect the other. The control chamber may comprise the or one of the pressure spaces, (Figs 1, 2 not shown) or be a separate chamber. The booster is preferably of the vacuum-suspended type. <IMAGE>
