Title: Moulded brake lining
IPC: F16D69/02
Filed: 1930-01-27
Abstract: 347,278. Brake linings. RAYBESTOSMANHATTAN, Inc., Passaic, New Jersey, U.S.A.-(Assignees of Abert, H. ; 80, Washington Place, New York, and Whitelaw, A.; 56, Aycrigg Avenue, Passaic, New Jersey, both in U.S.A.) Jan. 27, 1930, No. 2697. Convention date, July 8, 1929. Drawings to Specification. [Class 103 (i).] A brake lining comprises a hard-surfaced, readily frangible strip wound on itself in convolutions and having a permanent but somewhat resilient set whereby sections thereof approximate the curve of a number of differently sized drums. The ingredients used may be 10 lbs. rubber, 46 lbs. asbestos fibre, 4 lbs. magnesium carbonate, 10 lbs. litharge, 25 lbs. baryates, 5 lbs. sulphur and a rubber solvent, which are mixed in a dough mixer and formed into a strip by rolling, cutting or preferably extruding through a rectangular opening. The strip is dried and passed through pressing rolls. A woven asbestos-covered wired fabric may be added, the strip being forced into its interstices so as to leave the fabric exposed on one surface. The strip is then compacted and soft-vulcanized or " presscured " to such an extent that it can be handled. This is done in a " follower " which exerts a pressure of 1000 or 1500 lbs. and is heated. The strip is then bent with the wire fabric on the inside into the convolute form with curves approximating those of standard brake drums, and vulcanized to the desired hardness, the heat being gradually applied. The strip may then be ground, if ground on both sides it may also be used on an inner surface. To insure a flat surface the strip may be rolled between rolls which have a clearance which is somewhat concave-convex of the strip. The grinding may be carried out just previous to the hard vulcanization.

Title: Pressure-regulated diaphragm pumps
IPC: F04B43/067
Filed: 1972-01-21
Abstract: 1368689 Diaphragm pumps O TUCHENHAGEN 21 Jan 1972 [21 Jan 1971] 3040/72 Heading F1A In an hydraulically operated diaphragm pump for pumping a liquid which contains suspended solids (e.g. dirty water) from A to C through non-return valves 7, 9 and a tank 11 containing compressed air above the water level 13 means are provided for varying the quantity of hydraulic fluid (clean water) on the primary side 3 of the pump, so as to reduce down to zero the pump delivery rate and delivery pressure when the pressure in tank 11 exceeds a predetermined limit. On each movement to the left of piston 5 clean water is drawn from container 34 through lines 18a, 18, 21 and 28 past the open valves 14, 19 and 22 into the primary side 3 of the pump chamber, the spring-loaded valve 22 having been opened by the movement of diaphragm 1 to position 1a. On each movement to the right of piston 5 the diaphragm moves to position 1b to pump dirty water, whilst clean water is expelled from primary side 3 through line 29 and non- return valve 30 back to container 34. When the pressure in tank 11 is too high, member 15 (a diaphragm or piston) first throttles then closes valve 14 to reduce the clean water intake to primary side 3. Since a constant volume is expelled past valve 30 on each move to the right of piston 5, the diaphragm therefore loses its stroke and the pump its delivery capacity. A safety valve 35, for relieving the primary side of the pump in the event of a blockage in the secondary side or failure of the valve 30, is provided. A plurality of pumps as described above may be combined by arranging for them to share at least one common element such as a tank or reciprocating piston, but in all cases each  primary side is provided with an individual safety valve 35.

Title: Improvements relating to x-ray apparatus and methods of radiography
IPC: G21K1/02
Filed: 1950-02-07
Abstract: 683,408. Radiography. SCIENTIFIC & INDUSTRIAL RESEARCH, HONORARY ADVISORY COUNCIL FOR. Feb. 7, 1950 [Feb. 10, 1949], No. 3128/50. Class 98 (i). In making radiographs with apparatus in which the X-ray sensitive material is screened from the object to be radiographed by a Bucky grid, the grid and sensitive material are mounted for adjustment about a horizontal axis which is parallel to the plane of the grid but transverse to the length of the X-ray opaque strips in it, and the grid is reciprocated in a direction parallel to the said axis through a number of cycles of progressively decreasing amplitude during an exposure. The grid may be resiliently supported, as by leaf springs, so that when set in motion it executes a series of damped vibrations. As shown, Fig. 6, the Bucky grid 21 is mounted on a frame 19 by means of spring strips 22. Frame 19 fits against a frame 28 with the grid between them, Fig. 3, and carries a lead masking member 23 running on trackways. Frame 28 has an opening the size of the film to be exposed and registering with the grid, and mask 23 has an opening 24 one quarter this size. Frame 28 also has a covering sheet of synthetic resin 29a, and trackway 31 with a high flange 32 and a low flange 33. A fluorescent screen (not shown) is hinged at one edge to a flange of frame 28, and has a lead glass covering sheet. To make an exposure, mask 23 is moved away from the opening in frame 28, and an image is obtained on the fluorescent screen. A rotating anode X-ray tube is used and operates at low power with the anode stationary for screening. A lever 45, pivoted at 46, is rocked by a spring 50 so that a headed screw 43 at one end engages a bracket 40 on the grid 21 which is thereby moved into a position with springs 22 stressed A cassette 34 is slid along trackway 31 into the exposure position, one edge engaging a roller 48 on lever 45, which is rocked to release the grid, which thereupon executes damped vibrations perpendicular to the direction of the grid elements. A switch 53 actuated by lever 45 increases the power supplied to the tube and starts rotation of the anode. The radiographic exposure is completed and the tube switched off, e.g. by timing mechanism. To expose one quarter of the cassette at a time, the mask 23 is moved into the exposure position, and a lever 56, pivoted at 57 and acting as a stop for the cassette, is turned to stop the cassette when only half is in the exposure position. The first exposure is made through opening 24 in mask 23. For the second exposure lever 56 is turned into the position shown to stop the cassette when it is wholly in the exposure position. The cassette is then rotated through 180 degrees in its own plane, and two further exposures made in the same way.

A burner 21 is arranged in a chamber 19 and its combustion gases together with gases entering conduit 23 pass down into the furnace, through the firebox 13 and out through a conduit 24. The exhaust gases pass through a reversing device 25 to a thermal regenerator 2 which has a heat retaining mass 50 flowing through it. The gases from the furnace are passed into the regenerator through conduit 27, give up their heat to the upper part of the mass 50 in chamber 31 and pass out through outlet 43. The gas passes through a cooler 42, a separator 72, a blower 41 and inlet 38 to lower chamber 32 of the regenerator. This gas is heated by the lower part of the mass 50 in chamber 32 and the hot gas passes out of the regenerator through the reversing device 25 and back to the furnace via conduit 23. The upper and lower chambers 31, 32 are separated by a throat 33 which allows the mass 50 to circulate from the upper to the lower chamber but prevents gas transfer between the two chambers. The mass 50 is circulated by an elevator which receives it via a bottom air lock 34 and returns it via an upper air lock 35. A burner 22 is provided in a chamber 20 which together with the reversing device enable the flow of gases through the furnace to be reversed. The form box consists of a frame 60, Fig. 2, of cast steel with spheroidal graphite.
