Title: An anti-lock hydraulic brake system
Inventor: LATARNIK MICHAEL
IPC: B60T8/175
Filed: 1990-09-19
Abstract: An anti-lock hydraulic brake system having a master cylinder (2), a pump (16) an inlet valve (12) and an outlet valve (14) is characterised in that the inlet valve (12) comprises a piston (20) with control compartments (21, 22) interconnected through a throttle (19) and depending on the position of the piston (20), either the brake line (8) or the return line (13) is opened. The pump (16) feeds the brake lines during a brake slip control operation. When the outlet valve (14) is opened, a pressure gradient across the throttle (19) effects displacement of the piston (20) to the left to open the return line. During normal braking a second throttle (29) prevents switching of the valve to close the brake line in the event of vigorous pedalling. In another embodiment a pressure control valve and, optionally, also a changeover valve similar to the valve (12) may be provided in the inlet line so as to hold and prevent reaction on the brake pedal during skid control. <IMAGE>

Patent GB-2256952-A (GB)
Title: Computer transaction processing
Inventor: SPIRO PETER M
IPC: G06F11/34
Filed: 1992-06-12
Abstract: In a transaction processing system, snapshot records are stored in volatile memory along with volatile state memory records. Modifications to the volatile state memory records by the transactions are logged to an after-image log in non-volatile memory for recovery of the volatile state memory records. For recovery of the snapshot records in volatile memory, when any one of the records of volatile state memory are to be written from volatile memory to non-volatile state memory, the volatile snapshots records of the volatile state memory record are first written from volatile snapshot memory to non-volatile snapshot memory. This ordering of buffer pool flushing permits recovery of the volatile snapshot records from non-volatile state memory or from modifications in the after-image log. Moreover, recovery can be performed without writing modifications to the volatile snapshot records in an after-image log or flushing the snapshot records using an automic operation. <IMAGE>

Title: Servo control device, eg power steering valve.
Inventor: JORG WOLFGANG
IPC: B62D5/083
Filed: 1993-12-06
Abstract: The actuating shaft of the servo control device is subdivided axially into a primary shaft 1 and a secondary shaft 2 coupled elastically via a torsion bar 4 and a prestressed torsion spring 15 acting in parallel. Accordingly, a relative rotation adjusting a servo-valve arrangement 8 - 12 can occur between the two shaft parts 1, 2 only when the shaft is loaded by a torque which exceeds the prestress of the torsion spring 15. To simplify the construction, the legs of the prestressed tors spring 15 project into axial slots 13, 14 in the facing ends of the primary shaft 1 and bush 8 which is fast with the secondary shaft 2. <IMAGE>

Patent GB-2275877-A (GB)
Title: Centrifugal atomisation of liquids
Inventor: ROWLAND STEPHEN JAMES
IPC: A61M11/06
Filed: 1994-03-04
Abstract: The invention relates to the atomisation of liquids where control over droplet size is important, e.g. the nebulising of drugs to be administered to a patient by the inhaled route, where the deposition of the drug and its efficacy is a direct function of the droplet size. The object of the invention is to improve the control over droplet size, an objective met by a method and a construction where liquid is centrifugally forced through an orifice (4) sized to generate a droplet of the liquid of a required size. Thus, the liquid may be introduced into a drum with sized holes or pores in its wall or into a rotor formed by plates (1, 2) secured together with a spacing to provide an annular orifice of a required size, the rotation of the drum or rotor causing the forcing of the liquid through the holes or pores, or through the orifice, the centrifugal force and the Bernoulli effect causing the liquid to issue in the form of droplets of a predetermined size. <IMAGE>
Patent GB-2279276-A (GB)
Title: Cyclone separators
Inventor: LANGE NEVILLE ERNEST
IPC: B04C5/13
Filed: 1994-06-30
Abstract: A cyclone separator for gas, liquid(s) and solids has a tangential inlet 12 which may be closed or opened by moving the cyclone body or a piston-like member inside the body in the axial direction. As shown the body 1 in integral with a piston 13 subject to the fluid pressure between inlet space 8 and underflow outlet space 7, acting against spring 17. Body 1 moves to the left so that inlet 12 is closed by lug 16, and overflow outlet 26b is also closed. In other embodiments a piston moves inside the cylindrical part of the cyclone body to open or close the inlet. The piston is moved by the pressure of the fluid being separated or by an external ram or screw, in some cases against spring loading. A plurality of cyclones arranged in a common housing divided as in Fig. 1 enables more or fewer cyclones to come into use as the overall flow varies, with optimum flow through each cyclone in use. Not all the cyclones need to be adjustable. Springs 17 are of snap-action type, so that an inlet 12 is either wide open or closed. Different cyclones may come into use at different differential pressures. <IMAGE>
