Title: Improvements in and relating to disc brakes
Inventor: HENDERSON HENRY BELLAMY
IPC: F16D65/56
Filed: 1961-05-10
Abstract: 941,565. Disc brakes. AUTOMOTIVE PRODUCTS CO. Ltd. May 7, 1962 [May 10, 1961], No. 17052/61. Heading F2E. A disc brake, wherein the pads 26, 27 are each associated with a movable member 1, 4 which members are pivotally mounted about a common axis 9 so as to be swingable in a plane normal to the plane of rotation of the disc, has an operating member 17 which is pivotally mounted on the member 4 at 14 and is operatively associated with the member 1 at 20, 21 so that swinging movement of the operating member 17 causes the members 1, 4 to move in opposite directions to bring the pads 26, 27 into engagement with the disc. As shown the member 4 in the form of a flat plate having an aperture 5 therethrough which receives a peripheral portion of the disc (not shown) is positioned between the arms 2 of the member 1 and both members are mounted on a pin 9 carried by a flange 12 of a fixed support 10, the members 1, 4 being urged into contact with the flange 12 by the fingers 24 of a leaf spring 23. The end of the operating member 17, remote from the aperture 22 to which a pull rod is attached, has blocks 20 located thereon which engage the arms 2 of the member 1. The pads 26, 27 are located in recesses in the members 1, 4 and are located radially by shoulders on the backing plates 28. A hooped wire spring 34 the ends of which engage apertured lugs 37 of the backing plates 28 urge the pads away from the disc. A brake actuating means, Fig. 9, for operating two disc brakes fitted to pairs of wheels fitted to the same axle consists of a rectangular casing 38 having a hydraulic cylinder 40 therein provided with opposed pistons 43, 44 movable away from one another by applying fluid to port 41. Slides 45, 46 consisting of two members 48, 49 are associated with pistons 43, 44 respectively, the outer member 49 of each slide being connected by a sleeve 51 to a pull rod 52 which is in turn connected to the lever 17 of the associated brake. A lever 63 provides for hand operation of the brakes and is pivoted at 65 on an intermediate slide 66 carried by a bolt 68. On pivotal movement of the lever 63 the end 69 of the lever moves the slide 45 to the left and the reaction results in sliding movement of the slide 66 to move the slide 46 to the right which thus operates the brakes. Automatic adjustment of the brakes is obtained by adjusting the effective length of each rod 52 which is, for this purpose, screwed into the threaded bore 55 of the sleeve 51, relative rotation of which is effected by a ratchet wheel 56 and a pawl 57. The latter is carried on one end of a bell crank lever 58 pivoted on the member 49 at 59, the other end of the lever 58 engaging a pin 61 secured to the base of the casing. Excess movement of the member 49 on operation of the brakes results in the pin 61 pivoting the lever 58 so that the pawl 57 will engage a further tooth on the ratchet 56 which results on release of the brakes in rotation of the sleeve 51 to axially adjust the rods 52.

Patent GB-368167-A (GB)
Title: Regulating device for the supply of liquid to centrifugal separators
IPC: B04B1/12
Filed: 1932-06-12
Abstract: 368,167. Centrifugal machines. AKTIEBOLAGET SEPARATOR, 8, Fleminggatan, Stockholm. June 12, 1931, No. 17170. Convention date, June 21, 1930. [Class 23.] A centrifugal separator for continuous separation of liquids and solids has outlets 7, 9 for the light and heavy liquid components ; solids are discharged through the peripheral outlets 11, 16, and their discharge is assisted by a flushing liquid supplied through the pipe 14 to the space 13 between the outlets 11, 16. To prevent the treated liquid from being discharged with the solids, or the flushing liquid from entering the bowl, the supply of flushing liquid is varied in accordance with the quantity of separated liquids discharged. A vessel with two receivers 17, 18, Fig. 2, is suspended by a spring 23 and is connected by an arm 27 to a cock 26 in the supply pipe 14 for the flushing liquid. The light and heavy components of the separated liquid are led into the vessels 17, 18 respectively, which have outlets 21, 22 to control the flow from the vessels. When the vessels sink owing to the large quantity of separated liquid discharged, the cock 26 is turned to permit a smaller quantity of flushing liquid to flow into the space 13. The flushing liquid is thus prevented from entering the bowl by the openings 11. When the vessels 17, 18 rise owing to separated liquid discharging with solids through the apertures 11, the cock 26 is opened to admit more flushing liquid to flow into the space 13. In a modification the vessels 17, 18 are supported at one end of a lever and balanced at the other end by a vessel containing liquid before its treatment. The unbalancing of the arrangement operates the cock 26 in the pipe 14 of the flushing liquid.

Channel-opening. - In an insole-lip-turning machine of the kind provided with work-feeding means including a work engaging member moved to and fro in the general direction of the line of feed, this member co-operates with a rotary work support, moves to and from the plane of the work, and carries a a lip-turning part; a lipsetting hammer is provided which can be thrown into or out of operation at will; a lip support is reciprocated to and from the lip to crease the lip at its base; and an opener is provided for the inside channel, which is yieldably mounted and which can be moved to an inoperative position when insoles with no inside channels are being operated on. The machine comprises a work supporting table 8 normally raised by a spring 10 and depressed for the insertion of work by a treadle. The table is rotated intermittently by a pawl 11 operated by a link 14, and bell-crank lever 15, 18 connected by gear segments to a lever 21 oscillated by a cam on a shaft 5. A lip-turning plough 26 is adjustably secured to a bracket 27. A lip-setting hammer 29 and a slashing knife 51 are carried on parallel slides and operated by a cam-actuated lever 33 through latch plates enabling these tools to be thrown into or out of operation at will. The hammer is normally kept out of action by a spring 41. Its latch plate 36 has a horizontal slot 38 and a vertical slot 39. When the operator lowers the plate by a lever (not shown), a pin 37 on the knife bar is engaged by the vertical slot and the hammer is operated. The knife is reciprocated by a similar latch plate 58 controlled by a treadle. A fixed lip retainer 43, Fig. 3, engages in the angle formed by the upturned lip. A lip-support or anvil 44 is mounted to slide vertically in an arm 45 pivoted at 46. The anvil is backed by a spring 49, and is oscillated in timed relation to the hammer and knife so that it forms a crease at the base of the lip and has shear cooperation with the knife. A feed member 63 is given a four way motion to co-operate with the intermittently rotated work table in feeding the work. This member is adjustably carried at the end of a feed bar 64 reciprocated vertically by a roll 69 and sliding in a member 68 reciprocated horizontally by a cam-operated lever 74. The member 63 is formed with a wedge portion 63a to bend the lip backward.

Title: Improvements relating to Separators for use in Coil Annealing.
Inventor: MCKEOWN CHARLES GEORGE
IPC: C21D9/673
Filed: 1965-10-25
Abstract: 1,161,786. Convector plates for annealing furnaces. WELLMAN INCANDESCENT CO. Ltd. 5 Aug., 1966 [25 Oct., 1965; 22 April, 1966], Nos. 44996/65 and 17649/66. Heading F4B. [Also in Division C7] A separator for annealing metal coils has two superimposed rib systems which are related in such a way that the flows of gas through each of the two systems swirl in opposite directions, whereby the resultant gas stream is turbulent and substantially non-directional in the plane of the separator, thus increasing the efficiency of the gas-circulating impeller. One rib system may be a mirror image of the other system, while each rib in one pattern may extend across a plurality of ribs in the opposite pattern. The two rib systems may be secured directly to each other, or may be secured to either side of an annular intermediate plate. As shown in Fig. 2, rib systems 11 and 12 are secured to either side of plate 10. The ribs increase in width from the end adjacent to the annular periphery of the disc 10 to a maximum at their outer extremities.

Title: Improvements in and relating to fluid pressure control valve arrangements for compressed air brakes
IPC: B60T15/18
Filed: 1960-05-19
Abstract: 948,148. Valves; fluid-pressure brakes. VERWALTUNGSGESELLSCHAFT DER WERKZEUMASCHINENFABRIK OERLIKON. May 19, 1960 [May 21, 1959], No. 17655/60. Headings F2F and F2V. The inlet and exhaust valves 32, 22 controlling the application of pressure to a brake cylinder 14 are in the positions shown when the pressures in chambers 19, 21 on either side of a diaphragm 18 are equal, the inlet valve 32 being seated and the cylinder 14 open to atmosphere via a chamber 28 above another diaphragm 27, valve 22, orifice 24 and the chamber 25 beneath diaphragm 27, which latter is connected by the valve 22 to the diaphragm 18. When the pressure in chamber 19 is reduced by the driver through a pipe 11 for a light application of the brakes, the pressure in chamber 21, which is supplied from a constant pressure reservoir 12, lifts the valve 22 into contact with its seat 23 and closes-off the cylinder 14 from atmosphere; since the spring 39 of seat 23 is stronger than the inlet valve spring 36 continued movement of the valve 22 unseats the inlet valve 32 and air from a reservoir tank 13 flows to the cylinder 14 via chamber 28 until the pressure rise is sufficient to move the diaphragms down to the position where both valves are seated. The member 31 supporting both valves is pressure balanced due to the pressure in chamber 28 acting oppositely in chambers 56 and 51; the pressure in chamber 28 is also transmitted to another chamber 46 on top of a diaphragm 45 from which the member 31 depends, the resulting downward force, together with that of spring 36, being sufficient to seat the inlet valve 32 against the action of spring 39 when the pressure in the cylinder 14 is adequate for a full application of the brakes. Should the pressure in chamber 19 fall below the value corresponding to full brake application, the valve 22 and seat 23 are raised but the inlet valve 32 remains seated. The operating datums may be altered by changing the loading of the springs and the area of the diaphragm 45.

Title: Device for checking accuracy of shape
Inventor: BARBER CLIFFORD CHARLES
IPC: G01B5/20
Filed: 1957-06-04
Abstract: 882,075. Gauging departure from standard form. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Sept. 4, 1958 [June 4, 1957], No. 17706/57. Class 106 (2). [Also in Group XL (b)] A method of testing the profile of a workpiece by comparing it with a standard profile consists in preparing a trace 15 by tracking the standard 12 by a feeler 10 and then tracking the workpiece (not shown) in this apparatus without producing a further trace so that deviation of the marking point 11 (or a mark representing this) from the trace represents disparity between the workpiece and the standard and inaccuracies of the apparatus cancel out. The standard 12 is fixed to a table 1 which is mounted for movements in two perpendicular directions on a base 7. The table is then moved by hand so that a fixed feeler 10 travels along the outline of the standard 12. A fixed scriber 11 meanwhile traces a path 15 on a transparent plate 14 which is smoked or otherwise coated, the path 15 being representative of the shape of the article 12. To test a workpiece, it is fixed to the table 1 in place of the standard 12 and the scriber 11 replaced by an eyepiece 19 carrying a cross-line graticule or a tolerance circle 21 the centre of which occupies the position previously occupied by the scriber 11. An alternative arrangement is shown in Fig. 7 in which an image 15a of the plate 14, still carried by the table 1 (not shown), is focused on a screen 22 having a tolerance circle 28 marked thereon. In addition to this, a mirror 27 may be semi-silvered so that part of the light passes on to a masking plate 29, provided with a hole 30 through which light passes on to a photoelectric cell 31. In this case, the response of the cell merely indicates whether the path 15 is within the required tolerance. If, however, the plate 14 is formed as in Fig. 9, the area to one side of the trace being blacked out, then the response of the cell would indicate deviations from standard in either direction. In other embodiments, the table 1 may be pivotally mounted, or the feeler 10 may be carried by the table 1, the body to be tested being fixed on the base 7. Means may also be provided for enabling the body 12 to be tested along other sections.
