Title: Treating water to inhibit scale deposition
Inventor: ASHBEE DAVID WILLIAM
IPC: C02F1/48
Filed: 1987-03-11
Abstract: Apparatus (1) for conditioning water to inhibit scale deposition therefrom comprises a housing (2) having a water inlet at one end thereof and a water oulet at the opposite end thereof. An impeller (9) is rotatably mounted within the housing (2) along the longitudinal axis thereof, so that water flow through the housing serves to rotate the impeller.

Title: Vehicle wheel suspension assembling and alignment
Inventor: UCHIDA KUNINOBU
IPC: B62D65/12
Filed: 1987-06-29
Abstract: A vehicle wheel suspension alignment adjustment process in which, before a suspension sub- assembly comprising a pair of spaced apart wheel attaching members (a), a subsidiary frame (2a) and component members of the suspension, is assembled to a vehicle body (1), a sub-assembly attaching position of the vehicle body is measured, a deviation of the attaching position thereof from a reference position thereof is detected, and an alignment adjustment taking this deviation into account of the sub-assembly is carried out so that the resultant adjusted alignment has a predetermined value under the condition that the sub-assembly is thereafter assembled to the vehicle body. This process makes it unnecessary to carry out alignment adjustment of the suspension on a completed vehicle. <IMAGE>

Title: Method of rapidly opening disk files identified by path names
Inventor: CHRISTOPHER JR KENNETH WALTER
IPC: G06F12/08
Filed: 1987-12-10
Abstract: A data processing system has files stored on disks in a tree structure of directories and files. The system is operated to rapidly open files which have been recently opened or for which partial path information is available, by accessing a drive cache (30) in main memory (16). The cache has entries chained in a tree structure which is then searched to provide the same information during the opening process as that information which would otherwise have to be obtained from a disk (22). When the cache is full, a new entry replaces the least recently used entry.
Patent GB-2200734-A (GB)
Title: An apparatus for compensating the changes in water volume in a hot-water vessel
Inventor: KURZ DIPL-INGENIEUR ROLF
IPC: F24H1/18
Filed: 1988-01-11
Abstract: In the device, the water to be heated can be heated and stored in a water tank (5) which has a cold water supply and a hot water delivery. 
<??>In such hot water boilers, a thermal expansion of the water takes place during the heating period. In a closed water tank, this renders volume compensation necessary to avoid a harmful rise in pressure. 
<??>For the purpose of volume compensation and in order to avoid expansion water emerging in drip form at the consumer tapping point, there is connected fluidically to the water tank (5) a bellows (11) which can be extended via a pressure-controlled or temperature- controlled lifting device (13, 13') according to the temperature- conditioned change in volume of the heated tank water. 
<??>The volume-compensating device is suitable in particular for so- called open hot water boilers.

Title: Paper cutter
Inventor: SILVERMAN PAUL CONRAD ALEXANDE
IPC: B26B27/00
Filed: 1988-09-26
Abstract: A blade 1 has a forward-facing cutting edge 1' which rises from a base 3 substantially vertically or inclined backwards at an angle alpha  of less than 30% to the vertical. A resilient deflector 5 prevents the paper, card etc from riding up the edge 1' and the base is slid under the sheet to be cut. The blade is close to the plane of one side of the base 3 so that the sheet may be cut along the edge of e.g. a ruler. <IMAGE>

Title: A can crushing device
Inventor: MULLEY DAVID RICHARD
IPC: B30B9/32
Filed: 1990-04-11
Abstract: A can crushing device comprises a platform 27 upon which a can 37 to be crushed is supported, a plunger 23 which is movable between a raised position and a lowered position to crush the can, and means for moving the plunger between the raised and lowered positions. The device may also comprise a housing 19 to enclose a can. A can is located by projection 28, on the platform. A handle 26 acts through a pinion 21 and a rack 22 to raise and lower the plunger.

Title: Wheel lift mechanism for multiple axle vehicle
Inventor: TALBOT BRIAN
IPC: B60P3/32
Filed: 1990-12-22
Abstract: To lift one set of wheels (42) of a twin axle vehicle, such as a caravan, to facilitate non-powered manoeuvering of the vehicle, one of the sets of wheels (44) is mounted to its axle (48) by way of pivotal wheel carrier (52) and a piston and cylinder arrangement (60, 62) acts between a fixed member (65) and said carrier (52) to pivot the latter and raise or lower the attached wheels (44). In one arrangement (as shown) the wheels (44) on the pivotal carrier (52) are lowered, thus raising the other set of wheels (42) and the vehicle undercarriage. In an alternative arrangement (not shown) the wheels on the pivotal carrier may themselves be raised, leaving the other set on the ground. <IMAGE>

Title: Olefinic polymerisation using silylether initiators
Inventor: SHEPHERD NEIL
IPC: C08F4/42
Filed: 1991-02-06
Abstract: Process for anionically polymerising a conjugated 1,3-diene monomer consists of contacting the monomer in an inert hydrocarbon solvent with a monofunctional silyl ether initiator of general formula R<1>R<2>R<3>Si-O-A-Li where R<1> to R<3> are independently selected from monovalent organic substituent groups and A is a short chain hydrocarbon bridging group, to yield a polydiene having a molecular weight of typically 1,000 - 10,000, a high 1.4 content of typically 90 % and a low polydispensity of typically 1.15. The reactive ends of the living polymer chains may be terminated with a reactive group such as hydroxyl by treating the polymer with ethylene oxide. Subsequent removal of the polymer's relatively unreactive silyl end groups by reaction with tetra-n-butylammonium fluoride produces a difunctional, chain-extendable, hydroxy-terminated polydiene useful as a rubbery binder prepolymer.

Title: Closure locking mechanisms
Inventor: DOLMAN TERRY JAMES
IPC: E05B15/04
Filed: 1992-01-31
Abstract: A locking mechanism for a closure such as a window comprises a body containing a gear wheel 26 that is rotated by a handle 36. This rotation is converted to a linear locking action by actuating members 23 which are provided with a helical thread which engages helical teeth on the gear wheel. Rotation in one sense throws the members out of the body to perform a locking action on bolts 28, 29 and reverse rotation retracts the members into the body in an unlocking action. The position of the members 23 can be adjusted simply by screwing the members into and out of the body. <IMAGE>
