Filed: 1973-04-18
Abstract: 1415567 Document reading INTERNATIONAL BUSINESS MACHINES CORP 18 April 1973 [4 May 1972] 18591/73 Heading G4M The first column 14 (Fig. 1) of marks on a document 10 passing in front of a read head assembly represents the format of the data, e.g. that it is in binary coded decimal form and indicates controls which of the rows 1-12 of marks contain the coded information. In the embodiment of Figs. 4a-4b a window counter 116 (or delay circuit) provides a window signal for a predetermined time for each column of marks. For the first sensed character, that is the format character AND gates 126 are enabled so that sensed data is entered into a buffer 125. For subsequent columns AND gates 129 are sequentially enabled so that the sensed data is fed into register 134 via AND gate 133 controlled by the format data in the buffer 125. The contents of the shift register are transferred to an output register 140.

Title: Improvements in or relating to booster valves, particularly for controlling hydraulic brakes
Inventor: ANDERSON J EDWARD C
IPC: B60T13/16
Filed: 1956-06-18
Abstract: 800,924. Hydraulic brakes. BORG-WARNER CORPORATION. June 18, 1956, No. 18784/56. Class 103 (1). [Also in Group XXIV] In a control valve for an hydraulic brake actuator device in which the movement of a master cylinder piston 4 by a pedal member 67 is assisted by fluid pressure supplied by a continuously running pump 19, when the actuator pedal 67 is not pressed, the output from the pump 19 is blocked by closure of annular chamber 28. When the brake is actuated, as in Fig. 2, the spool 44 is so moved that the passage 29 in sleeve 24 is partly opened to the space surrounding the spherical end of valve member 56 so that a thrust is transmitted through spring 41 and member 33 to the master cylinder piston 4. When the piston 4 has moved through a certain distance, as shown in Fig. 3, the passage 29 is reclosed by expansion of the spring 41. The brake may, if necessary, on failure of the pump supply, be applied by direct mechanical action by forcing member 44 into engagement with member 32.

July 3, 1933, Nos. 18821 /33, 30370 /33, 2518 /34, and 15756/34. [Class 108 (i)] In refuse carts and other containers an arcuate duct or curved tube is provided which is rotatable about a horizontal axis and is normally disposed curved upwards with an open mouth at one end against which a dust bin is adapted to be secured, the other end entering an opening in the vehicle body and means are provided for rotating the duct with the bin to discharge the contents of the bin into the vehicle &c. As shown, the duct is formed in two telescopic parts 7, 8 pivoted on a shaft 9, the open outer horizontal end having sealing means 15 against which a dust bin may be secured, while the other end 12 passes into an opening into the vehicle body. The bin is placed in a cradle 31 which is then raised by means of a cable 28 in a fixed vertical duct 23 until the bin abuts the mouth 15 of the arcuate duct 7, 8 which then rotates to shoot the contents into the vehicle. The upper part of the duct 23 may be closed at the side by a part 18 fixed to and rotating with the duct 7, 8. The bin is guided by channels 35 until it is engaged by guides in the arcuate duct 7, 8. The cable and duct 7, 8 may be driven by a motor 11 which is controlled by switches 39 or may be automatically controlled by means of members such as 35, 25<a> mounted on the cradle 31 and arcuate duct 7, 8. In a modification, the arcuate duct may be in one piece and the bin held against the sealing mouth 15 by means of a hook forming part of a member pivoted to the duct 7, 8 and engaging a fixed cam slot. In another form the arcuate duct may have a vertical depending portion against which the bin is secured by a cam, the arcuate duct with its vertical depending portion then being rotated to discharge the contents. Guides may be provided in the interior of the body to distribute the refuse to various parts and the body may be rocked about a pivot for the same purpose and tipped about the same pivot to discharge its contents. A bar may be provided whereby the motor is stopped in the event of an obstruction to the raising of the bin.

Abstract: 1359266 Aerials THOMSON-CSF 18 April 1973 [21 April 1972] 18865/73 Heading H4A An offset Cassegrain type aerial comprises a chassis 4, a primary source 1, a sub-reflector 2, a main reflector 3, and a screening cap 6, which covers the source and the sub-reflector, and which is lined with wave-absorbing material. The aperture of the source and the sub-reflector are above the main reflector, and the cap, which has independent means securing it to the chassis, protects them from the effects of wind, rain and snow. It also acts as a screen against external parasitic radiations, whilst reducing side lobes from the aerial, and levelling its gain over its operating frequency band. As described, the chassis 4 is made of tubular members which are welded together. The main reflector 3 and the primary source 1, which is of hog horn type comprising a reflector, are bolted directly to the chassis. The sub-reflector 2 is carried on a tubular frame 5, which is secured to the chassis. The cap 6 is shaped as one half of an ellipsoid of revolution, with a semicircular cross-section on a plane X-X. It has an inner layer of graphiteloaded plastics material foam arranged in juxtaposed small cones, an intermediate layer of close-woven metallic mesh, and an outer layer of stratified plastics material (Fig. 2, not shown). Curved tubular members within the wall of the cap are joined together near its front, emerge from the wall and within the cap near its rear, and are bolted to the chassis (Fig. 3, not shown).

Abstract: 505,326. Moulding and lining pipes centrifugally. HUME PIPE CO. (SOUTH AFRICA), Ltd. June 29, 1938, No. 19267. Convention date, Dec. 18, 1937. [Class 87 (ii)] A pipe is lined with bituminous material by introducing the material in comminuted form and, while rotating the pipe to line it centrifugally, liquefying the material by heat applied within the pipe and then allowing it to solidify. As shown in Fig. 1, a flanged steel pipe 2 is provided with detachable end plates 6 and is rotated on rollers 4. Comminuted bituminous material is introduced and spread evenly by a rod 10. The speed of rotation is increased and the bitumen is melted by a flame thrower 11 and then allowed to cool or cooled by water to form the lining 9. The end plates 6 may be recessed at 8 so that the lining extends beyond the pipe to make a good joint with an adjacent pipe. For plain ended pipes the plates 6 are replaced by rings 12, Fig. 2, which are afterwards removed and their places filled with bitumen. Local weaknesses in the lining may be repaired by introducing powdered bitumen at the point, centrifuging, and then melting and solidifying the bitumen. In a modification, a concrete pipe, which may have metal reinforcement therein, is formed centrifugally from a pulp of cement and asbestos or aggregate until it is self sustaining. Rotation is then stopped and water and slurry is drained out of the interior after which the concrete pipe is lined with bitumen, as previously described, before the concrete has completely set.
