Title: Load controller having time integrated demand
Inventor: STEVENSON ROBERT HOUSTON
IPC: G05D23/275
Filed: 1982-07-14
Abstract: A load controller, intended for use with a stored energy heating apparatus and similar to that of Specn. No. 2042767A, is described. Further control arrangements use a microprocessor to ensure that a thermal storage heater has received an appropriate charge at the end of a supply "on" period, the processor basing its calculated value of desired storage temperature on the heat store temperature drop during one or more discharge periods, and receiving updated inputs of ambient and storage temperature during a charging period. Digital display and a keyboard input are provided for adjusting system constants and evaluating unit operation. A further refinement permits the processor to ensure that charge rate is limited if a maximum permitted electrical demand of the premises would otherwise be exceeded.

Title: Cleaning heat exchangers
Inventor: MARGRAF ADOLF
IPC: F28F1/02
Filed: 1983-09-21
Abstract: Flattened cooling pipes 2 comprising plane vertical lateral surfaces are installed horizontally in vertical rows within a housing 1. The plane lateral surfaces are swept over by scrapers 3, 4 jointedly secured on pendularly suspended supports 5 under contact with the lateral surfaces, and these lateral surfaces are cleared of adhering dust whilst doing so. The supports are suspended on chains or ropes 10 in the upper part of the housing 1 and are placed in pendular reciprocating motion by a drive 13, 14 separate from the suspension. To prevent jamming of the scrapers between the rows of pipes which may warp under particular circumstances, the rows of pipes 2 are kept at a precise spacing by a spacing element 9 or by several spacing elements 9 installed at identical intervals. To this end, the scraper supports are rigidly interconnected, so that a single drive only is needed for the coupled supports. <IMAGE>

Patent GB-2140849-A (GB)
Title: Vertical-hook compound mat
Inventor: QUANTE HEINRICH
IPC: E21D11/15
Filed: 1984-05-31
Abstract: Compound mats for the lagging of the lining in the roadways of underground mining works and tunnel constructions are interconnected by a mat lock connection in which the longitudinal bars 3 are bent around at one end to form a vertical hook 10 and are made deformable at the other end. The deformation, in conjunction with the vertical hook 10 and a sliding ring 25, forms a "load distance part" 12. The deformation is produced by a plate 15 bend upwards on the other side of the sliding ring 25 and rigidly connected to longitudinal bar 4. When tractive forces occur the sliding ring 25 is drawn over the plate 15 and caused to perform deformation work. By varying the "troughing" of the plate 15, the plate thickness and the shape of the sliding ring 25 a characteristic curve advantageously corresponding to the prevailing conditions can be obtained. An alternative load distance part (not shown) takes the form of a wire which is bent hairpin-wise and which is bound to be compressed by the sliding ring when the compound mats are subjected to loads. The wire preferably forms a horizontal loop which is additionally bent out of the plane of the loop so that on the reversal of the deformation of the loop or wire an additional "knot'' is formed which increases the deformation resistance and keeps it constant over a long period. <IMAGE>

Patent GB-2149230-A (GB)
Title: Electrical track distribution system
Inventor: HANKIN JOHN IVOR
IPC: H01R25/14
Filed: 1984-10-17
Abstract: The distribution track comprises an elongate panel of box section, with a longitudinal aperture (4) in one side. The edges of the aperture define lips (12) of differing thickness, with electrical conductors (6, 10) on the inwardly facing surface of the lips. An earth conductor (8) is also located on the back inner surface (36) of the panel. The plug (28) has a spring loaded center earth contact (32) and two lateral protrusions bearing contacts (30, 34) thereon. The plug is inserted into the aperture and rotated through 90 DEG  to bring the contacts into electrical contact (30, 32, 34) with the respective conductors (6, 8, 10). A cam formation (36) on the plug prevents it from being rotated more than 90 DEG , and the differing thickness of the lips and corresponding difference in the thickness of the contact-bearing protrusions prevents incorrect orientation of the plug. <IMAGE>
