Title: Plate heat exchanger
Inventor: BALLA ARNOLD
IPC: F28D9/00
Filed: 1986-12-18
Abstract: A heat exchanger comprises profiled heat exchanger plates which are assembled in such a manner that flow channels, the height of which is small compared with the width and length but substantially greater than the thickness of the plates, are formed between the plates.

Title: Anti-skid-controlled brake system
Inventor: FENNEL HELMUT
IPC: B60T8/82
Filed: 1987-09-17
Abstract: A circuit configuration for an anti-skid-controlled automotive vehicle's brake system which is controllable in accordance with a time-division multiplexing method has a resetting-device (5)-equipped master cylinder (3) for a braking pressure generator (2), the wheel brakes (11-14) being connected to the master cylinder (3) via electromagnetically-operable multi- directional valves (15-18). The arrangement is such as to ensure that, during anti-skid control. the sequence of pressure control in the wheel brakes (11-14) and/or the intervals in which the wheel brakes are connected to the master cylinder (3) are dependent on the rotational behaviour of the wheels. According to one embodiment, the braking pressure reduction has priority during anti-skid control as long as the pressure reduction times required for regaining the running stability of a wheel lie under a maximum valve (Tmax). When the maximum value (t6; Tmax) has been reached, priority of pressure reduction is temporarily suspended in favour of a pressure build-up in the wheel brakes of one or more stable-running wheels (VR). <IMAGE>

Title: Cache memory apparatus
Inventor: ISHIDA ITSUKO
IPC: G06F12/12
Filed: 1989-01-20
Abstract: A cache memory apparatus allocates tag memory regions 2 and data memory regions 3 on the basis of an attribute of the information to be cached. The needed memory region according to the attribute (e.g instruction, data or quantity) is then accessed before caching is implemented. Accordingly, data processing systems incorporating the apparatus dispense with the need for a plurality of cache memory apparatuses corresponding to the number of attributes, thus saving chips and providing compact systems. A multiple processor system allocates cache memory regions to each data processor and accesses the needed memory region in accordance with information specifying a given data processor before caching is implemented. Consequently, the need to provide a plurality of cache memory apparatuses corresponding to the number of data processors is avoided. <IMAGE>

Title: Self-portrait lens attachment with partially reflective surface
Inventor: HOUGHTON JOHN ERNEST
IPC: G02B3/00
Filed: 1989-12-07
Abstract: A meniscus lens 1 of zero power and with a partially-reflective coating on e.g. its convex face 2 is mounted in front of a camera lens. The partially-reflective convex surface 2 faces forwards toward the subject of the photograph, who sees in it a reflected image which is identical with the image in the camera viewfinder. The diameter of the meniscus lens may be made sufficiently large to avoid vignetting of the image formed inside the camera, and the radius of curvature of the convex surface may be chosen to produce a reflected image of the same field diameter as the image in the viewfinder. A square or rectangular frame (7, Fig. 2) may be fitted in front of the meniscus lens to show more precisely the boundaries of the image formed within the camera. The lens 1 may have a finite converging power and be used as a supplementary close-up lens. <IMAGE>

Title: Materials handling system including separation and measurement stages
Inventor: DALY JAMES HINSHELWOOD FAIRLEY
IPC: E21B21/06
Filed: 1989-12-22
Abstract: A materials handling system (10) receives material for an in-flow pipe (11) which delivers into a distribution box (17). Box (17) delivers to a fraction separator (12) from which a first fraction is collected by device (13) and a second fraction is collected by device (14). A sensor (20) associated with device (14) provides a weight measure of the second fraction to a control unit (22). The system is particularly applied to the material discharged from down-hole drilling operations. The separator (12) includes a sieve mesh (16) which retains larger solids which move over its surface to be collected in the receptacle (14) where the sensor (20) measures weight. When a predetermined weight has been collected, the control unit (22) causes the receptacle (14) to discharge. Fines and liquid passing through the mesh (16) are collected in the receptacle (13), where a measure of flowrate may be made by a sensor (26). Density of the inflow, and vibratory state of the sieve mesh (16) are also measured and supplied to the control unit (22). Assessment of the nature and quantity of the various discharges is made. <IMAGE>
