Title: Improvements in brick or block making and pressing machines
IPC: B28B13/04
Filed: 1950-12-06
Abstract: 711,594. Brick-moulding machines. MORGAN, I., and HANLON, E. G. March 6, 1952 [Dec. 6, 1950], No. 29856/50. Class 87 (2) In order to turn a brick issuing from a brick press into a suitable position for sanding or rusticating, a pivotable carriage actuated in synchronism with the piston of the press is adapted to receive a brick in one position from the press and to present the brick in a relatively turned position, the carriage receiving the brick when its supporting surface is in a substantially horizontal position, and actuating means are provided to turn the carriage through substantially a right angle, thereby tipping off the brick in the turned position on to a substantially horizontal receiving surface. When the crosshead 8 of the press moves downwards it. depresses a lever 5 which in turn moves levers 6, 7, upwards, and when the crosshead moves upwards the levers 6, 7 move downwards under their own weight and cause the, lever 5 to rise with the crosshead. The pivotable carriage 9 is in the form of an angle plate and is mounted so that it receives a brick from a shoot 11 as the crosshead 8 moves, upwards. The lever 6 is connected by a link 10 and universal joints 6A, 10A to an arm 9C on the carriage 9. When a brick has been deposited on the horizontal side of the carriage the crosshead 8 moves downwards and the lever 6, moving upwards, causes the carriage to turn through a; right angle and deposit the brick face upwards on a conveyer 13. The lever 7 moves in synchronism with the lever 6 and is connected thereto by a crossbar 21 on an extension of which a link 14 is pivoted. The link 14 operates a bell crank 16A which, through a link 17, advances a crosspiece 19 and slide rods 20 when the lever 7 rises, i.e. when the carriage 9 returns to its former position after depositing the brick, the rods 20 there causing a pusher 30 to push the last brick right up to the column of bricks already on the conveyer. The arrangement is duplicated for a double type brick-moulding machine, in which case, if the bricks are required in single column on the conveyer, an additional lever, secured to the sleeve 4 which-carries the levers 6, 7, operates a tranverse pusher whereby the last brick deposited by one carriage is moved into line with the last brick deposited by the other carriage.

Abstract: 741,214. Testing tackiness of adhesive surfaces. DUNLOP RUBBER CO., Ltd. Oct. 18, 1954 [Oct. 30, 1953], No. 29997/53. Class 106 (2). A portion of the adhesive surface to be tested is wrapped round a cylindrical wheel 1 rotatably mounted in a bracket 3 to which is attached a guide formed by two parallel rods 5 on which a weight 4, connected by a spring 6 to the bracket 3 may freely slide, an indicator 7 being provided to indicate on a scale 8 the deflection of the spring 6 when the weight is slid along the guide away from the holder. In use the wheel 1 on which is wrapped a strip of the surface to be tested, is held within an aperture 11 of a plate 10 against another part of the surface for a given time, the weight is then raised slowly along its guide until the adhesion is overcome, whereupon the spring 6 recoils, the guide rods 5, support 3 and wheel 1 being carried upwardly until buffer springs 9 contact the weight 3. The index 7 grips the scale with sufficient friction to remain in the position of the maximum spring extension prior to this recoil. For the next and subsequent tests the wheel 1 is rotated to bring a fresh portion of the strip into contact with the next surface area in the aperture 11. A polygonal prism may be substituted for the wheel 1. In another embodiment the guide is formed by a cylindrical tube and two springs in series are utilized so that the rate of the combined spring is varied at the upper portion of the range.

Abstract: 1343198 Subaqueous structures COMBINATIE WESTERSCHELDE VOf 28 June 1971 [26 June 1970] 30219/71 Heading E1H An underwater structural element, e.g. a tunnel element 4, is provided with a sand foundation layer by the injection of a sand/ water suspension from a floating suction dredger (not shown) through pipes 10b, 10 and nozzles 11 into the space beneath the element. A crater 14 is stated to be initially formed by the creation of a sand dyke 13 between the bottom 3 and the element 4, the suspension supplied to crater 14 eventually flowing out of it to fill the whole of the space below and possibly alongside the element, and displacing unwanted silt 40 before it as it does so. The element 4 which has already been coupled to a previously laid element may be supported on adjustable temporary supports 6 during this process. Correct positioning of the adjacent elements may be ensured by controlling the pressure and/or the sand content of the injected suspension, or by varying the ballasting of the sunken elements as the sand foundation is being laid. Pressure detectors may be provided on the bottom of the element. The injected suspension may cause some lifting of the element. Once the foundation has been laid, nozzles 11 and adjacent zones 37 are filled with cement mortar.
