IPC: E04B1/78
Filed: 1989-06-09
Abstract: A building brick, block or the like 1 has facing surfaces 2 & 3 defining the heat transfer area of the brick or block, the surfaces being separated by a distance B. The brick or block has 10 to 90% by volume of voids 4. The characteristics of the voids are as follows:-   (a) individual voids, are of high aspect ratio A /d where A is the area in square millimetres of the notional plane of maximum cross-sectional area of the void and d is the maximum dimension in millimetres of the void in the direction perpendicular to its notional plane of greatest cross-section, the values of A and d being the same or different for the individual voids,   (b) the value of d is 6mm or less; (c) the perpendiculars to said notional planes of greatest cross-section lie within 30 DEG  of the perpendiculars to said facing surfaces. (d) the high aspect ratio voids, are so arranged that at least 40% of the heat transfer area has at least N voids in series in the path of heat flow i.e. from one facing surface to the other, where N is B/16 (which if non integral is rounded up to the next integer; and (e) at most 30% of the heat transfer area has no voids in said path of heat flow.   <IMAGE>
Patent GB-2222875-A (GB)
Title: Plate heat exchangers
Inventor: LEVEN WITEK
IPC: F28D9/00
Filed: 1989-08-08
Abstract: In plate heat exchangers for ventilating which are used for air entering and leaving, problems arise when the air entering has low temperature. This results in a cold corner (A) appearing in the heat exchanger and its efficiency thus being reduced. The object of the present invention is to reduce the effect of the cold corner by introducing throttling means (9) along a number of the channels (3) for air leaving. The throttling means (9) are protrusions of equal size along one and the same channel, but different in the different channels (3), the channel (3) with the smallest throttling means (9) being located closest to the inlet for the air entering.

Title: Stencil holding and registering apparatus
Inventor: SCHMID OTTO E
IPC: B41F15/36
Filed: 1990-08-20
Abstract: When a screen printing stencil 11 is clamped in retaining apparatus 12, the accuracy of register which existed during exposure of the screen printing stencil 11 may be lost for the motif.

Title: Brake booster
Inventor: WATANABE MAKOTO
IPC: B60T13/57
Filed: 1992-02-13
Abstract: A manually operable brake booster is also able to operate automatically. A front bead (17b) of bellows (17) separating a chamber (A') from a constant pressure chamber (A) is supported by and urged against the wall surface of a front shell (2) by a support member (15).
