Abstract: 1,041,223. Air heating apparatus. OATLEY TECHNICAL DEVELOPMENTS Ltd. March 4, 1963 [March 2, 1962], No. 8294/62. Heading F4S. In an incandescent gas fire 4, behind the radiants of which is an air heater 6, air is passed through the heater 6 from an outside supply 24 by a power-driven fan 26 and then directed into ducting 7 leading to dampered warm air outlets 27, 28, Fig. 1 (not shown), which may be disposed in other rooms 9, 10. The ducting 7 may be at one side of, or in, the combustion products flue 8. Air drawn from the room 5 into the fire casing 17 is heated by passing it around a convector heat exchanger 18, above the radiants and heated by combustion products passing round an internal baffle 19, and is then returned to the room through a grille 23. Fins 21 extending from the flue outlet pipe 20 further heat the warm air leaving the heater 6 in the ducting 7. The heater 6 may be divided by a vertical corrugated partition. The fan 26 may be located below the air heater as in Fig. 1, outside the room 5 as in Fig. 2, or in the warm air ducting 7.

Patent GB-199795-A (GB)
Title: Improvements in and relating to the purification of clay
IPC: C04B33/13
Filed: 1922-03-27
Abstract: A process for the purification of clay comprises peptization of the clay in an aqueous solution of caustic alkali, such as caustic soda, which contains the hydrate of an alkaline-earth, such as hydrate of calcium, barium or strontium, the amount of reagents added for suspending any given clay being varied according to the hardness of the water used.  The solution of mixed hydrates may be obtained by the interaction of an excess of caustic alkali and an alkaline-earth hypochlorite such as bleaching powder in the presence of water.  The suspension of clay may be separated from the unpeptized impurities when such are present, and the clay recovered in any desired manner. A soluble hypochlorite may also be present in the liquid for bleaching, deodorizing and sterilizing the clay, in which case a longer period of contact is usually necessary, or the hypochlorite may be added to the suspension after the impurities, if any, have been removed.

Title: Pressure measuring apparatus
IPC: G01M3/28
Filed: 1976-03-04
Abstract: 1474662 Pressure gauges BRITISH GAS CORP 4 March 1976 [4 March 1975] 8888/75 Headings G1L and G1S A gauge for indicating change of pressure comprises an open ended pipe 1 with a shut-off valve 2 at one end; a sealed vessel 12 from which a narrow bore tube 11 extends; and a glass tube 8 connected via Hg traps 9, 10 to the pipe wall 6 and to tube 11. To detect leaks in a gas pipe 5 the pipe I is screwed into pipe 5 so that the vessel 12 extends into it. The system is pressurized via pipe 1 and gas passes into the vessel 12 until its pressure equals that of the pipe 5. This causes a Hg slug 13 to move along tube 8. The position of the slug can be adjusted by changing the system pressure via bleed valve 3. Loss of pressure in pipe 5 results in gas from the vessel 12 forcing the slug to the right until the pressures in the vessel and pipe equalize.

Abstract: 648,811. Thermionic valves. M-O VALVE CO., ALDOUS, W. H., and TREMLETT, C. A. March 22, 1946, No..8889. [Class 39 (i)] A thermionic valve of the " common grid " type for generating ultra-high frequency oscillations has the two external tuned circuits coupled by means of a discrete condenser connected between anode and cathode, such connection passing through and being insulated from the grid. The cathode is formed of two semi-circular box-like parts 13, and the cooperating surfaces 18 of the anode 10 have a like shape. The grid 11 comprises an annulus having a cross-piece 15 supporting the grid wires 16. The condenser is a ceramic disc 24 of high permittivity, metallized on both surfaces. The upper surface is soldered to. a screw 28 entering the anode 10, while the lower surface is attached to the cathode by a spring finger 22 passing through an aperture 23 in the grid. The Provisional Specification also describes modifications in which one plate of the condenser is formed by the anode itself, and its capacity may be varied by having the corresponding part of the anode movable and adjustable from outside the valve. A further modified form of condenser has interleaved cylindrical plates.

Filed: 1976-03-05
Abstract: 1501333 Adjusting disc brakes for wear BENDIX CORP 5 March 1976 [2 April 1975] 08946/76 Heading F2E In a reaction type sliding caliper disc brake, having a mechanical actuator which includes a force-transmitting element 40 of adjustable length, a ratchet mechanism 68, 64 operable between an actuating piston 34 and element 40 indexes when element 40 moves away from the disc by more than a predetermined amount and increases the length of the element on subsequent brake application. Pawl 68 is pivoted at 70 to piston 34 and biased by a spring 72 so that when spring 74 returns element 40 by more than a predetermined amount, the increased separation between element 40 and piston 34 causes the pawl to index over a ratchet tooth. Subsequent brake application pivots the pawl thereby rotating nut 56 to increase the overall length of element 40. A spring 76 which has its ends located in slots in the flange 62 (Fig. 3, not shown) prevents the nut from rotating in the opposite sense during brake release. The mechanical actuator is as described in Specification 1497242.

Abstract: 435,470. Kinematograph cameras. SCHEIBELL, G. B., 9, West 16th Street, New York, U.S.A. March 23, 1934, No. 9126. Convention date, April 14, 1933. [Class 97 (i)] In cameras comprising a film magazine capable of occupying two different positions, and means for feeding the film in opposite directions relatively to the magazine, the magazine carries two film take-up means respectively rotatable from opposite sides of the magazine, and alternatively engageable with driving means in the camera ; the construction permits driving means, operated in one direction only, to feed the film in opposite directions through the magazine, in the two positions of the magazine. As shown, the camera 1 has a magazine compartment 2 closable by a hinged lid 3 carrying a spring 3<a> to press the magazine into exposure position. Each end of the magazine has an exposure aperture 46, a feedclaw slot 48, and an aperture 48<a>, which respectively register with an exposure aperture 13, a feed claw 5, and a film-retaining pin 4, in the camera, when the magazine is in the camera ; the openings are so arranged that rotation of the magazine about a vertical axis, during change of position, is necessary to effect registration in the two positions. The exposure apertures are of slightly less width than half the normal image width, and the use of the apparatus produces a film having two ranks of relatively inverted images which, upon division of the film longitudinally, and union of the parts end-to-end, produces a film having a single rank of images in the proper order. The openings in the end of the magazine at which exposure is effected last may be covered with a protective strip 14 held by adhesive at its ends. Reels are provided within the magazine and are alternatively rotated through pins 31 on crank discs 30 extending from opposite sides of the magazine to engage alternatively a fin 8 on a driven gear 7 in the camera ; a recess 10 in the camera wall houses the pin which is not in use. The reels each comprise an inner collar 19<a>, Fig. 4, and an outer collar 19<b>, a spring 19<c> being inserted between them, and a film-securing clip 36 being provided on the outer collar. One of the reels is mounted on a fixed spindle 25, Fig. 4, and is rotated by a key 27 extending from the disc 30, the disc being carried by a removable side of the magazine. The other reel is carried by a fixed sleeve through which a spindle carrying the disc 30 extends, connection between the spindle and reel being effected by a set screw and key-way. The film is wholly enclosed by the magazine during exposure and is held against the exposure apertures by guide members carrying rollers.
