Title: A power assisted vehicle steering system
Inventor: ADAMS FREDERICK JOHN
IPC: B62D6/02
Filed: 1985-10-02
Abstract: A power assisted vehicle steering system has a rack and pinion steering gear 6 incorporating a servo motor 6a controlled by a valve 22. A fluid pressure supply line 3 to the valve 22 includes an axially adjustable spool 5a of a regulating valve 5 which is adjustable by speed responsive means 19, (which may be a solenoid or stepping motor) to increase the restriction to fluid flow to the valve 22 as vehicle speed increases. A flow control valve 7 is responsive to fluid pressure in the line 3 upstream of the valve 5 and to fluid pressure in the line 3 downstream of the valve 5 so that a pressure differential across the valve 5 is sensed by spool 9 which is displaced to open the supply line 3 upstream of the valve 5 and a reservoir 1. This latter opening reduces the supply of pressure fluid available for actuating the servo motor 6a and the available power assistance as the vehicle speed increases. The spool 5a has opposed faces in a recess 5b (which recess throttles flow in the line 3) and fluid pressure on these faces provide opposed forces which balance the spool axially with respect to its adjustment by the speed responsive means 19. <IMAGE>

Title: Pressurised fluidised bed reactor
Inventor: JUDD MICHAEL ROBIN
IPC: C10J3/56
Filed: 1985-10-15
Abstract: A method of operating a circulating fluidized bed having a draught tube and a circulating fluidized bed apparatus (10) including a housing (12), a draught tube (14) and separate feeds (17, 34) for two different fluidising fluids involves feeding different fluids into the apparatus via the feeds (17, 34) when the housing (12) contains a charge of particulate material, causes fluidizing of the material and circulation of the fluidized material up the interior of the tube (14) and downwardly in the housing outside the tube; and causes two essentially different processes to take place in two essentially separate process zones in the bed, respectively inside and outside the tube (14). In accordance with the method the distribution of the two different fluidizing fluids is such that they are kept essentially separate at the inlet (14.1) to the tube (14), so that one of the fluids passes essentially only up the interior of the draught tube, and not upwards through the fluidized bed outside the draught tube, and the other fluid passes upwards essentially only up through the fluidized bed outside the draught tube and not up the interior of the draught tube. <IMAGE>

Title: Gun systems
Inventor: BUXTON ANTHONY CHARLES
IPC: F41F/
Filed: 1986-11-21
Abstract: A gun system comprises a gun carried in a carriage, a supporting structure for the carriage having a construction which upon recoil of the gun permits the carriage to move with a controlled curved motion having a vertically upward component relative to the supporting structure. In one embodiment, the gun 1 is mounted in a cradle 3 and has its elevation varied by means of arms 11 the length of which is adjusted by means of a gearbox 17. In order to assist stabilisation of the system upon recoil of the gun, trunnions 5 at the rear of the cradle 3 are allowed to run up a track 7 (for low angles of elevation of the gun, eg below 30 DEG ). Return of the cradle 3 and gun 1 to the firing position may be assisted by return springs or recuperators (not shown). <IMAGE>

Title: Portable carbonating apparatus
Inventor: HULLEY PETER
IPC: B67D1/04
Filed: 1986-12-23
Abstract: A portable carbonating apparatus includes dosing means to control the amount of gas delivered to the body of liquid being carbonated each time a gas valve (3) is operated. The gas valve delivers gas into a dosing chamber (7) having an outlet controlled by a second valve.

Title: Plastics bottles & method of reducing gas permeability
Inventor: HART REGINALD JAMES
IPC: B65D23/08
Filed: 1987-06-04
Abstract: The invention provides an injection blow moulded plastics bottle having a label on the outer surface thereof comprising a gas barrier for reducing or preventing the permeation of gasses through that part of the wall of the bottle covered by the label. The invention also provides a method of reducing sorption losses of carbon dioxide from a carbonated drink contained in an injection blow moulded plastics bottle by filling the bottle with carbon dioxide under pressure until the material of the bottle has absorbed some of the carbon dioxide prior to filling the bottle with the carbonated drink. Filling of the bottle with carbon dioxide may be effected during bottle blowing by using carbon dioxide as the blowing medium. Alternatively, the bottle may be filled with carbon dioxide after bottle manufacture but before beverage filling.

Title: Binary dosage system
Inventor: CURNOW RAYMOND C
IPC: G01G15/02
Filed: 1988-07-13
Abstract: A method of, or apparatus for, adding contents to a container in which predetermined dosages are added in response to a binary signal. The binary signal is generated a measuring station and represents any deficiency in the actual quantity of the containers contents compared with a predetermined minimum value. The size of each dosage corresponds to a value represented by a digit of the binary signal. Doses of material in multiples of weight W, e.g. W, 2W, 4W, 6W and 16W are supplied from a case provided with a Power discharge shutter. In the case a rotary disc is provided with different sized through bores 3 of varying diameters corresponding to the weight multiples. A leveling blade 7 bearing against the top surface of the disc separates the case into a filling cavity 8 and a discharge cavity 9. In response to the digits of the binary signal the disc is rotated to position the required filled bores 3 one at a time in the discharge cavity and the shutter is opened to enable a container to be filled. The dosing stations may be linearly spaced. <IMAGE>

Patent GB-885628-A (GB)
Abstract: 885,628. Multiplying-machines. ATVIDABERG-FACIT A.B. Oct. 14, 1960 [Oct. 15, 1959], No. 35369/60. Class 106 (1). A motor-driven cam-disc and pin-wheel calculating machine has a keyboard, and on depression of a key, the key is connected with a constantly driven member which then completes its depression. The invention is applied to the machine described in Specification 850,622 in which after depression of a key an escapement mechanism including a five-toothed member 8 is actuated to allow the pin-wheel rotor to move laterally through one step. Only one of the ten keys is shown. On depression of a key, its lever 1 is rocked about a shaft 2 and cam slots 1a, 1b rock bails 3a, 4b respectively. The slot 1b is so shaped for each key that a toothed segment 4 secured to the bail 4b is rocked by an amount corresponding to the number of the key for the correct setting of the cam disc in the setting position. The bail 3a shifts a link 5 which actuates a motor switch 15 and moves a roller 7 into a notch of the member 8 so that on operation of the escapement mechanism, the link 5, bail 3a, and consequently the depressed key, will be restored. On depression of the key, a coupling member 9 is lifted and its cam surface 9a by engaging a rod 11, causes teeth in the member to engage a rotating snatch roll 10 which completes the movement of the member, and so of the key. At the end of this movement, the surface 9a allows the member 9 to be withdrawn from the snatch roll 10 under the action of a spring-loaded bar 12. As the escapement mechanism operates after the setting of the cam-disc, levers 14 and 13 are rocked by the member 8 to withdraw the rod 11 so as to allow the member 9 to remain disengaged during the restoration of the key.

Title: Wall tie
Inventor: WILSHAW GRAHAM
IPC: E04G23/02
Filed: 1989-04-04
Abstract: First anchoring means (14), at the inner end of the wall tie in the cavity wall (50, 52), is mechanically expansible by rotation of the rod (10), e.g. to draw frusto-conical nut (26) into slotted metal sleeve (18), or in another version (not shown) to cause a compression nut to deform a compressible sleeve. Over-expansion of the relevant sleeve is prevented by breakage of the rod (10) at a break-off point (e.g. neck 44) near its outer end when a predetermined torque is applied. The break-off point is protected upon insertion of the wall-tie into the bore (54), which may involve tapping, by an overlying sleeve, preferably in the form of a cap nut (41). This sleeve is also adapted for engagement by the tool (48) for rotating the rod (10) and is removed and discarded along with the broken-off end portion (46). <IMAGE>
