Patent GB-272886-A (GB)
Abstract: 272,886. Dupuy, H. June 18, 1926, [Convention date]. Gas-heating furnaces.-A process for heating gases and vapours consists in passing through a combustible mass a fuel or combustible for raising the mass to the required temperature and the fluid to be heated alternately. A shaft a having conical screens f on its interior wall contains the combustible C resting upon a grate b below which is a lower chamber d of larger diameter provided with a door e for the removal of cinders. Air is supplied by pipes o, g to the chamber d by a conduit k having openings m and to the free spaces behind certain of the screens f in the shaft a. A pipe i provided with a damper p<1> is disposed at the upper part of the shaft for the outlet of smoke. When the required temperature has been reached the damper i<1> and cocks p in the air pipes are closed and the fluid to be heated is admitted by a conduit h, traverses the mass of combustible and passes through openings l in the chamber d to a conduit j and outlet pipe n. To ensure rekindling of the mass C when air is next blown in a small quantity of combustible may be maintained ignited outside the fluid conduit.

Title: Improvements relating to hose couplings
IPC: F16L33/22
Filed: 1952-10-30
Abstract: 714,028. Hose couplings. BIEGEL GES., O. Oct. 30, 1952 [Nov. 14, 1951], No. 27302/52. Classes 99 (1) and 99 (2). A coil spring ring 3 surrounds the end of a hose 2 fitted over a nozzle 1 substantially stationary relatively to a clamping member such as a screwed ring 6 integral with the nozzle, and a clamping member 4 having a coned surface is screwed onto the ring 6 to cause the ring 3 to force the hose into engagement with the nozzle 1, and when tensional load is applied to the hose the ring 3 adheres to the hose and is moved towards the smaller end of the coned surface of the member 4 to urge the hose radially inwards towards the outer surface of the nozzle. The nozzle 1 may be provided with an annular bead 8, and ports 7 so that with unintentional release of the coupling pressure fluid in the hose escapes through openings 9 which may comprise a whistle and thus act as an alarm signal. The ring 3 may be enclosed in a rubber tube; alternatively, each convolution of the ring may be surrounded by rubber, or the ring may be embedded in a vulcanized solid rubber ring. In a modification, the opposed ends of two hoses are connected by a double-ended spigot internally of a tubular socket onto which members 4 are screwed, the wall of the socket being provided with an aperture through which passes a screw engaged in a flange of the spigot so that the spigot and socket have a limited amount of relative movement.

Title: Improved indicating instrument
IPC: G01C5/06
Filed: 1939-10-06
Abstract: 535,389. Altimeters ; counting-apparatus. BENDIX AVIATION CORPORATION. Oct. 6, 1939, No. 27381. Convention date, Oct. 7, 1938. [Classes 106 (i) and 106 (ii)] Comprises an instrument having means for pre-setting it to a desired indication in either direction, wherein means are provided for indicating the magnitude and direction of the pre-setting. The invention is described as applied to an altimeter. The movement is carried on a frame comprising front and back plates 11, 10 connected by spacers 13 and is enclosed in a casing 15 communicating with the atmosphere through an opening 15a. An aneroid capsule 19 transmits movement through pivoted links 22, 47, 48 to a spindle 41. This spindle through a rack 78 and pinion 79 drives a spindle 75 carried by an angle arm 70 mounted on a shaft 24 in alignment with the spindle 41 and carrying a cam wheel 25. The spindle 75 transmits movement through rack and pinion 77, 62 to a spindle 49 in alignment with the spindle 41. The motion of the spindle is transmitted by crown wheel 63 and spindle 59 to a needle 68 and also by crown gear 51, pinion 52, shaft 53 and rack and pinion 56, 58 to a needle 61. The gears are such that the pointers 61, 68 indicate hundreds and thousands of feet respectively. To pre-set the hands a knob 37 is pushed in against a spring 40 and through gears 39, 39, 29 and crown gear 27 25, the shaft 24 and arm 70 are turned so that the spindle 75 is carried around the spindle 41 and wheel 79 about its sector 78. At the same time, a counter 35 is driven through gears 29, 31 and bevels 33, 34 to register the setting. Counting apparatus.-The spindle 84 carries a disc 89 having a tongue 88 driving the lower denomination 87 of the three counter wheels 87, 86, 85. The wheel 85 carries a shield 90 with a " minus" sign. The spindle 84 also carries a disc 89a which through a tongue drives the lower denomination wheel 87a of counter wheels 87a, 86a, 85a with the numerals on the drums or wheels arranged oppositely to the counters 85, 86, 97. The wheel 85a carries a shield 94 having an opening 95 and having arranged around the periphery a series of " zero " and " plus " signs. In the zero position of the counter, the shield 90 is just below the left-hand edge of opening 91 and the opening 95 of shield 94 just below the left-hand edge of opening 91a. The reading is therefore 0000 -. Counter-clockwise rotation of shaft 84 then registers 0001 + and so on to a maximum of 8990+. When the destination of the plane is below sea level, it is necessary to give a minus setting. When the shaft 84 turns clockwise from zero the wheels 85, 86, 87 turn simultaneously to attempt to indicate the next numeral and so bring the shield 90 into opening 91. Further rotation of the shield is prevented since the wheel 86 is stopped at nine-tenths of a revolution clockwise. The numerals of wheels 85a, 86a, 87a appear now in their opening 95 in the slot 91a with the minus sign to the left.

Title: Improvements in or relating to filters for air and gases
IPC: B01D46/42
Filed: 1936-10-09
Abstract: 483,022. Filtering gases. VOKES, C. G. Oct. 9, 1936, No. 27461. [Class 8 (ii)] A filter has interchangeable or reversible parts for permitting cleansing of the filtering surfaces by liquids. As shown, the air is filtered by passing through the upper parts of frames 11, 12, 13, while the lower parts of the frames are cleaned bv immersion in oil. The frames are reversible in guides 15 in a casing 2, 3, the lower part 3 of which contains the oil and is detachably secured to the upper part 2 by means of screws 4. The air enters the casing through an open-work panel 6 and passes under a screen 17, which extends below the surface of the oil. A deflector 20 extends beneath the screen 17. The air then passes through the filters 11, 12, 13 to the outlet 7, in front of which is placed an oil-retaining screen 21, having perforations 25. The frames 11, 12, 13 carry filtering fabric which is of progressively finer mesh and lesser area from the first to the last frame. In another arrangement, filtering screens are washed by liquid which flows from an upper to a lower tank. When all the oil has flowed down the tanks are reversed.

Abstract: 1,094,530. Gripping apparatus. BASON & SONS Ltd. Oct. 3, 1966 [July 1, 1965], No. 27831/65. Headings B8A and B8H. In a brick handling apparatus, the bricks supplied on an endless conveyer belt 12 abut a stop (16) (Fig. 3, not shown) and thereby actuate a pneumatic pusher 21 to feed the bricks into a gripper device 24 for inversion and lateral separation before being released thereby. The gripper device is more fully described in Specification 1,086,810. On release by the gripper device 24 the bricks are each gripped between the horizontal portions of a pair of L- shaped tines 45 and withdrawn from the gripper means. The vertical portions of the tines 45 are pivoted about horizontal pivot pins 46 and their uppermost ends are urged apart by springs 47 and have an inflatable tube 48 mounted therebetween to provide on inflation the brick gripping force. The fingers 45 are mounted on a carriage 41 slidably mounted on guide-rails 42 and movable therealong by a pneumatic ram 37 between the gripper device and an intermittently movable endless conveyer belt 49. The conveyer passes over rollers 53, drive roller 50 and a tensioning roller 54 and is advanced one brick length at a time to enable the bricks to abut end-to-end. The pneumatic rams of the pusher 21, the gripper means 24 and the carriage 41 and the endless conveyers 12, 49 are operated in synchronization by means of appropriate circuitry (not shown). In an alternative embodiment (not shown) in which the bricks are advanced to the conveyer 49 without inversion, the gripper means 24 may be replaced by a suction-operated device forming the subject of Specification 1,052,641.

Title: Improvements in knitting machines
IPC: D04B15/64
Filed: 1936-10-14
Abstract: 487,148. Straight - bar machines. DEHN, F. B. (Textile Machine Works) Oct. 14, 1936, No. 27933. [Class 74 (ii)] In a full-fashioned straight-bar machine, yarn-carrier rods are selectively engaged by a sliding member carried by the friction-box, which member is operated by means shiftable longitudinally of the machine, and independently of the friction-box. The friction-box 12, carries a slide 14 with nose 16 for engaging notches 17 in dogs on the thread-carrier rods 10, 11, and is provided with notches and. a detent to prevent accidental displacement. At its rear end, the slide has a slot 22 receiving an arm 23 on a shaft 24 rocked by cams 43, 53 on the main cam-shaft 45 through links 26-33. A notch 64 in the link 33 is held by a spring 34 in engagement with a shaft 35, journalled in a forked arm 36 on a shaft 38. The shaft 35 carries a wheel 42 maintained in contact with the cam 43 by a spring 40, Fig. 3. Shaft 35 also carries a wheel 51 on a sleeve capable of being slid into and out of engagement with the cam 53, by a lever 50 operated by a rod 55 and pattern chain 62..As shown in the Figures, with the roller 42 in contact with the cam 43, the slide 14 is connecting the rod 10 with the friction box. Air traversing the slot 22 in the slide 14 leaves the arm 26, which remains in the same position, as movement of the bell-crank lever 28, 32 due to movement of the roller 42 by the cam 43, is lost between adjustable stops 29, 29<1>, on the rod 27. On returning to the original position, the slot 22 again engages the arm 26. If a button 61 on chain 62 now rides under a projection 60 on an arm 56, the roller 51 is slid into contact with the cam 53, the low spot of which coincides with the high spot of cam 43, and rotation of the shaft 45 rotates the bell-crank 28 counterclockwise, draws down the rod 27, and moves the slide 14 into engagement with the rod 11. If the cam-shaft 45 is shifted longitudinally for narrowing, while the cam 43 is in operation, an idler cam 44 moves into the path of wheel 42, and holds it against the action of the spring 40. If the cam 53 is engaging the wheel 51, a plate 54 on the side of the cam engages the side of the wheel 51, and keeps it in contact with the cam-surface, until the friction is sufficient to overcome the spring 52. To throw the gear out of operation, the rod 33 is raised by a handle 67, and pressed forward, so that a second notch 66 engages the shaft 35, and the bell-crank arm 28 is raised to the stop 29<1> on the rod 27, and a stop 68 on the arm 32 engages a set-screw 69, preventing further upward movement of the arm 28. In a modification, to enable the change to be made at any point, the arm 23 is splined to the shaft 24 and moves with the friction-box. Additional cams, rollers, and pattern-chains, allow of the selective employment of additional yarn-carrying rods. Rebound of the rods is prevented by notched plates on their ends, with co-operating spring detents on the machine.
