Abstract: 1395284 Carbon filaments BAYER AG 9 March 1973 [10 March 1972] 11412/73 Heading C1A [Also in Division H5] Filaments of carbon are produced from filaments of polyacrylonitrile by first heating the acrylonitrile filament under tension at a temperature between 150‹ and 190‹ C. in an oxidizing atmosphere, then heating under tension in an intert gas atmosphere at a temperature between 250‹ and 300‹ C., then without tension at a temperature between 200‹ and 250‹ C. in an oxidizing atmosphere and finally carbonizing without tension in an inert gas atmosphere at a temperature above 900‹ C. The fibre used preferably has a denier of from 0À9 to 5À0 d tex, and a tensile strength from 1À35 to 9À0 p/d tex. The tensile stress employed in the oxidizing stage is preferably greater than that used in the inert gas treating stage. The carbon fibres obtained may be subsequently graphitized e.g. at 1600 to 2600‹ C. in an argon atmosphere. The filaments obtained may be coated and bound with resin for use as reinforcement.
Patent GB-812703-A (GB)
Title: Automatic brake adjustment mechanism
IPC: F16D65/54
Filed: 1956-04-16
Abstract: 812,703. Automatic adjustment mechanism for brakes. GOODYEAR TIRE & RUBBER CO. April 16, 1956 [Oct. 6, 1955], No. 11476/56. Class 103(1). In an automatic brake adjustment mechanism for a brake actuated by a piston and cylinder mechanism, a smooth cylindrical adjustment pin 21 is secured to a cylinder closure member 15 and extends axially within the cylinder, friction gripping means 32 being provided within the hollow brake piston 10 holding the pin against relative axial movement during normal travel of said piston or brake engagement but permitting movement when the friction lining wear occurs. In the applied position of the spot-type disc brake illustrated, an axially slidable brake disc 4 is rotatable with wheel 1 and is frictionally engaged by friction pads 11 when the cylinder 12 is pressurized to force the piston and disc axially into frictional contact with friction pad 9 secured to the stationary housing 8. The automatic adjusting mechanism consists of a coiled spring 31 mounted about a bushing 28 with one end abutting piston 18 and the open end abutting flange 30. A spacer sleeve 33 loosely encompasses the pin 21 between the friction collar 32 and the part 17 of the piston and the length of spacer sleeve is less than the axial space 20 of the piston less the thickness of flange 29 and width of collar 32 by an amount equal to the normal piston movement during a brake application. With the parts shown in the brake applied positions in Fig. 1 the clearance between the end of the sleeve 33 and the piston wall 17 provides normal operating clearance and upon release of brake pressure spring 31 moves the piston 10 to the left to bring piston wall 17 into engagement with sleeve 33 to reestablish normal clearance between disc 4 and friction pads 9 and 11. The arrangement is such that should the piston move the desired amount without the brake being applied, the friction collar 32 will then be forced along the pin 21 to a new position where the brake block 11 will engage the disc 4. In a further embodiment disclosed in Fig. 3, a smooth pin 73 housed in a disc member 67 closing the end of a cylinder 62 in the non-rotatable brake support. The head 74 of pin 73 has a limited movement axially relative to the disc member 67 against the resistance of a spring member 75 to provide the normal operating clearance of the brake. The piston 63 is provided with a split spring ring 79 mounted, whilst under tension, on the pin 73 such that when the piston 63 is moved axially of the cylinder under fluid pressure, the pin 73 is moved with the piston 63 to the limit permitted by the clearance between the head 74 of the pin and its confining elements; denoting normal brake clearance. Should such movement be insufficient to permit application of the brake, the piston will be moved along the pin against the frictional resistance of the split spring ring 79 to a new position where friction pads engage the brake disc 61.

Abstract: 1441886 Controlling printing XEROX CORP 15 March 1974 [19 March 1973] 11576/74 Heading B6C [Also in Division G2] A printing or copying machine, e.g. a xerographic machine, has means for registering the number of prints or copies that it is desired be made by the machine; and means for preventing actuation of the machine if the registered number lies within a predetermined range, e.g. 2-9 copies inclusive. This ensures that a high-speed copier is only used for runs where its use will be economical. A single copy is allowed to be made to check operation of the machine. The control circuitry may include two counters, one sets by the operator to register the number of copies desired, the other indexed by counting the number of copies, the machine stopping on coincidence of the two counters. Further means may be provided to override the means for preventing actuation to enable any number of copies to be made.

F., 23, Cross Flatts Avenue, Dewsbury Road, Leeds. April 23, 1932, No. 11733. [Class 40 (v).] A photophone uses approximately monochromatic light. A neon-filled glow-discharge lamp T is used with sodium in the envelope and associated with a heater which keeps the lamp at such a temperature that the light emitted corresponds to the sodium D lines. When the heater is not used the light is ordinary neon red. The light is directed to the receiver by a parabolic mirror adjusted by a sighting-device. The lamp is in the output circuit of a valve 6, to the grid 8 of which the signals are applied. The valve is shunted by a resistance 7. According to a modification, the lamp is connected across the anode battery 4, Fig. 3 (not shown). At the receiver the monochromatic light is separated by a filter, Fig. 4. (not shown), or by a prism P behind a diaphragm D1 and in front of a diaphragm D2 which is adjusted to select the desired colour. The receiver is directed towards the transmitter by a sighting- device.

Abstract: 1469843 Medical filter SHERWOOD MEDICAL INDUSTRIES Inc 15 March 1974 [25 April 1973] 11753/74 Heading BID [Also in Divisions A5 and C7] A filter element of sintered stainless steel is made by screening particles of irregular shape to exclude those outside a given size range, mixing the remaining particles with 0.05 to 0.5% weight of lubricant e.g. wax, pressing them to form a self-supporting 'green' filter element and heating the element in two stages to burn off the lubricant and sinter the particles. Particle size ranges exemplified are 44-74 and 125-149 microns, which produce elements capable of retaining 99% of impurities above 3 and 10 microns dia. Numerical details of pressures, dimensions and sintering parameters are disclosed. The element may be cup shaped as shown or rounded or flat. The element is then force-fitted into a tube of polypropylene, polycarbonate or polyethylene terephthalate and heated by induction (Fig. 4 not shown) to form a peripheral seal therewith.
