Patent GB-2131108-A (GB)
Title: Hydraulic brake pressure proportioning valve
Inventor: REINARTZ HANS DIETER
IPC: B60T8/26
Filed: 1983-11-16
Abstract: In a proportioning valve integrated into or connected to the housing (3) of a master cylinder of a vehicle brake system, the valve closure member (30) is provided on a control piston (23) which is slidable by the action of fluid pressure against the force of a control spring (45). With its end remote from the valve closure member (30), the control piston (23) projects into a chamber (46) which is sealed against the master cylinder pressure. The chamber (46) communicates, via the channel (47), with the master cylinder reservoir. As the chamber (46) is therefore not in direct communication with the atmosphere, the displacing motion of the control piston (23) will not be impaired by contamination or corrosion; it also cannot be impaired by the development of an increased pressure or a pressure below atmospheric pressure in the chamber (46). An arrangement of two in-line valves integrated into a tandem master cylinder housing is also described (Fig. 5 not shown). <IMAGE>

Title: Animal feed
Inventor: HOOGSTAD BRUIN
IPC: A23L19/10
Filed: 1984-02-13
Abstract: A starch-rich meal, such as tapioca, is subjected to hydrolysis by a heat-stable alpha-amylase enzyme capable of hydrolysing starch to dextrins having a degree of polymerisation (DP) in the range 4 to 10, the hydrolysis being conducted at a solids content of at least 50%, typically greater than 60% by weight. This produces a viscous liquid product useful as a binder/conditioner in pelleted animal feedstuffs. The process is conducted preferably by passing the meal and enzyme rapidly through a heated reaction vessel.

Title: Removing unwanted water
Inventor: HOWE SYDNEY
IPC: E21F16/00
Filed: 1984-06-01
Abstract: A method of removing unwanted water, particularly from mines, comprising coupling a pressurised water supply to the input side of a prime mover, the mechanical output side of said prime mover being connected to a water pump which is operable to pump said unwanted water to a collection point or collection means. The water at the input side of the prime mover is less in volume and higher in pressure, or vice versa, than the water exitting from the pump. The prime mover is a reciprocating piston, or a hydraulic motor, mechanically connected to the pump.
Patent GB-2146123-A (GB)
Title: Apparatus for monitoring displacement
Inventor: COLLIER MARTIN JOHN
IPC: G01F23/16
Filed: 1984-07-31
Abstract: A member 4 is arranged so that its displacement controls the position of a piston 3 in a cylinder 1 having a gas-filled cavity 2. The cylinder 1 contains a block 8 of material which, when illuminated with pulses of electromagnetic radiation from a light source 6, generates pulses of acoustic energy, causing vibration of the gas within the cavity 2. The frequency of the vibration depends upon the frequency of the pulses of incident electromagnetic radiation and the resonant frequency of the cavity 2, which in turn depends upon its dimensions. Hence by monitoring the frequency of the vibration, the displacement of the member 4 may be found. The frequency of the vibration may be determined using an optical interferometer comprising two optical fibres 11 and 12 connected in parallel and combined at a return optical fibre 13. A feedback loop may be provided via amplitude detector 15 to cause the frequency of pulse generator 5 to approach the resonance frequency of the cavity, and the member 4 may be brought to a desired position by the feedback loop including hydraulic control circuit 19 and actuator 17. <IMAGE>

Title: Method and apparatus for applying a ring of material to a centrifugal casting mold
Inventor: NOBLE CHARLES H
IPC: B22D13/10
Filed: 1984-09-05
Abstract: Establishing a ring of particulate material on the internal surface of a centrifugal casting mold (1) when the ring, which can be either an end ring or an internal ring, has axial dimensions small in comparison to the length of the mold. The ring is established by confining a quantity of the particulate material in a cavity (18) of a tool (3), inserting the cavity into the mold, rotating the mold and the cavity at substantially the same rate adequate to apply substantial centrifugal force to the particulate material in the cavity, and opening the cavity to release the particulate material while continuing to rotate the mold and the cavity. The detailed construction of the tool differs according to whether it is for use to establish end rings or interior rings. If the particulate material contains a binder low speed rotation of the mould is used during establishing the ring. Preferably, however, the particulate material is binderless and the mould is rotated sufficiently rapidly both to retain and densify the material whereby it may be contoured as the tool is withdrawn to complete formation of the ring. <IMAGE>

Title: Apparatus paying off strand
Inventor: BAILEY COLIN IDRIS WATKINS
IPC: B65H59/06
Filed: 1984-12-17
Abstract: Wire (3) is drawn through a guide (4) at a point along the axis of a non-rotating bobbin (1), the wire passing over a circumferential rim (2) (which may be one rim of the bobbin or a freely-rotating spinner disc). A retarder is provided in the form of a cylindrical array of bristles (6) which project from a base (7) and extend parallel to the bobbin axis to contact the rim. With the wire sliding around the rim, the wire contacts the successive bristles and deflects them radially outwards, so that the wire is appropriately retarded. The deflection of the bristles is however small so that they are less susceptible to fatigue. The base may be formed in two halves placeable onto a reel rim from diametrically opposite sides, and may be adjusted along the axis of the reel. The bristles may be of plastics, carbon fibre or spring steel material. <IMAGE>

Title: File allocation
Inventor: KITAJIMA HIROYUKI
IPC: G06F12/12
Filed: 1985-12-13
Abstract: A method for optimum allocation of files to storage devices is disclosed in which in order to realize a desired hit ratio, number of writes, and read/write ratio within suitable ranges and to reduce the number of steps for file allocation judgement, the actual hit ratio for the cache of each of the files stored in storage devices with cache and the read/write ratio are measured and calculated and whether they are greater than values specified respectively therefor or not is judged. Further, when using an integrated circuit external storage device, the number of accesses to it is measured, and whether the number thus obtained is smaller than a specified value or not is judged. Files are reallocated on the basis of the judgement, the storage capacity of the devices, and allowable utilisation rates of the devices. <IMAGE>

IPC: G05D23/13
Filed: 1986-02-25
Abstract: In a valve for mixing hot and cold water having a rotatable control knob 7 which is manually operable to adjust the relative proportions in which hot and cold water are mixed and including means for maintaining mixed water at a constant temperature, a stop 72 engageable with an abutment 49 on the valve body 9 to limit rotation of the control knob 7 to provide mixed water having a pre-determined temperature is movable by resilient biassing means to a position clear of the abutment to allow further rotation. In the preferred embodiment the knob 7 has an outer body 50 keyed for rotation with an inner bush 55 by interengageable spline formations permitting axial sliding movement of the body so on the bush 55. The stop 72 is integral with the body 50 and a spring 63 acts between the body 50 and bush 55 to position the stop 72 for engagement with the abutment 49. The stop 72 is releasable to permit rotation of the control knob 7 to provide mixed water having a temperature higher than the predetermined temperature by sliding body 50 axially outwards on the bush 55 against the biassing of spring 63 to raise the stop 72 clear of the abutment 49 (Figure 5). <IMAGE>

Title: Fluid coupling transmission
Inventor: SHUTE ANTHONY GEORGE
IPC: F16H48/18
Filed: 1986-03-14
Abstract: A fluid coupling (27) for a power transmission system of a front wheel drive vehicle provides, where necessary, a four wheel drive facility for the vehicle. The coupling (27) comprises an enclosed rotary fluid pump (27) having a chamber (28) permanently filled with fluid which is trapped in the chamber. An input shaft (16) from the vehicle power unit is connected to the housing (29) of the pump and the output shafts (18) to the rear wheels are connected to independent rotors (32) (33) in the pump. Rotational movement of the rotors relative to the housing results in a pressure build-up within the pump which can cause the rotors to lock-up relative to the housing if, for example, the front drive wheels slip and there is a substantial difference between the speeds of the front and rear wheels. <IMAGE>
