IPC: F24C15/12
Filed: 1937-11-13
Abstract: 487,480. Hinges &c. ; lids for cooking- stoves. STOVES, Ltd., and RICHARDSON, W. H. Nov. 13, 1937, No. 31243. [Class 65 (ii)] [Also in Group XI] A lid 3 for a domestic cooker, cabinet, or other container is both pivotally and longitudinally displaceable in succession relatively to the container, and has one or more tapered elements 15 which guide the lid when it is pivoting and act as wedges when it is longitudinally displaced, so that the lid is maintained firmly in the open position. The flange 14 on the lid has slots 22, engaged by pins 23 carried by brackets 24 on the container. These brackets have cam surfaces 25 over which the elements 15 ride when the lid is being opened and shoulders 26, against which the inclined edges 17 of the elements 15 abut to give the wedging action when the lid is upright. The elements 15 also taper downwardly in front view and the brackets 24 are narrower behind the shoulders 26 than in front of them, to receive the lower parts of the elements 15. The rear part of the flange of the lid is slotted at 19, and reinforced by correspondingly slotted members 20. Brackets 21 at the back of the container engage in these slots when the lid is open.

Abstract: 281,286. Moya, R. G. Nov. 24, 1926, [Convention date]. Stopping and starting arrangements; stop-motions acting on failure of selvedge-forming thread. The selvedge-forming thread from a bobbin acts on an arm 22, Figs. 5 and 6, of a light member 22, 23 and thus turns the arm 23 thereof into position to lower an arm 24 on a rod 25 turnable in a boss 26 on a hand lever or grip 27 mounted on a spring-controlled bar 28 connected by a lever to the loom belt-shifting block. The rod 25 is provided with a counterpoise 30 and with an arm 29, which, when the bobbin thread fails, is moved into the path of a lay member 32. The hand lever 27 and bar 28 are thus turned, a, stop or screw 33 on the bar 28 entering a notch 34, thus allowing the bar to be moved endwise by its spring to stop the loom. The hand lever 27 is used to re-set the parts in operative position. Specification 227,865, [Class 142 (ii), Looms, Kinds &c.], is referred to.

Title: Heat exchanger
Inventor: JAEGER ULRIC RICHARD
IPC: F28F13/00
Filed: 1966-07-13
Abstract: 1,146,657. Tubular heat exchangers. OLIN MATHIESON CHEMICAL CORP. 13 July, 1966, No. 31515/66. Heading F4S. A heat exchanger 10 has disposed within its outer casing 15, a plurality of tubes 18 having preferably an elliptical cross-section, with the major axes lying radially (Fig. 2, not shown), and being secured to suitably apertured endplates 19 and 20. Between, and surrounding the tubes, there is a body of pervious material 29 which extends the full length of the tubes and is held in place by concentric cylindrical screens 16 and 17. The pervious body may be formed for example of particulate material or by weaving or knitting metal wire into a mesh which is then arranged in a plurality of layers. Sintering, brazing or soldering may then be used to produce a bond between the constituents of the body and between the body and exchanger components. Inlet and outlet connections are arranged so that a first heat exchange fluid, to be heated or cooled, enters through inlet 21, flows in the direction of the broken arrows through the tubes 18, and then leaves through outlet 27. A second fluid, to be cooled or heated, enters through inlet 24, fills an annular space 31 and is then forced to flow radially, taking the direction of the solid arrows, through the pervious body, around the tubes and into a central passage 30 from where it enters an outlet 28. In a modification (Figs. 5-8, not shown), the inlet and outlet connections for the first fluid both lie along the exchanger axis and the second fluid inlet and outlet are both formed in a single fitting (123), which projects from the centre of the exchanger. As in the first embodiment, the second fluid is caused to flow through the pervious body in radial directions.

Title: Improvements relating to slicing machines
IPC: B26D7/24
Filed: 1931-11-14
Abstract: 375,681. Machinery guards. BERKEL & PARNELL'S SLICING MACHINE MANUFACTURING CO., Ltd. and THOMAS H., Aden Road, Ponders End, Middlesex. Nov. 14, 1931, No. 31564. Addition to 351,134. [Class 80 (iv).] Access to the knife of a power-driven bread or like slicing-machine by way of the substanceholder or slice-receiver or both is prevented by the closure of guards associated with interlocking-means preventing opening thereof except when power is cut off, re-establishment of the power drive preferably being prevented until the guards are closed. As applied to a machine of the kind described in Specification 368,839, the tiltable slice-receiver 19, 19a, Fig. 1, is guarded when in normal position by a fixed guard 23 in the vicinity of the knife-casing 15, and the holder or loading-tray 16 by a guard 20, the front 20a of which can be raised on hinges. The power circuit includes switches 26, 27, 29, Figs. 1, 3, and 4, all of which must be " on " when the motor 12 is running. To tilt the receiver in the direction of the arrow B, it must first be moved axially away from the casing 15 after operating a locking-handle 24 in the direction of the arrow A. This can only be done when, on opening the switch 27, an arcuate rib 32, Fig. 3, has moved from beneath a lug 31 on an extension 30 of the handle 24 lying in the switch-casing 28, the releasing-movement of the handle allowing a tumbler 33 to fall into the path of the rib 32 to prevent closure of the switch 27. The guard part 20a carries an arcuate member 40, Fig. 4, with a channel 41, which is concentric with one of the guard pivots 22 and can pass the switch 29 only when this is in its " off " position. On fully raising the guard 20a, the channel 41 engages the switch 29 to prevent its closure. As applied to a beltdriven machine, Figs. 6 and 7, the belt-fork 73, 74 is carried by a sleeve 75 supported by a rod 76 and a tube 59, which is mounted in standards 51, 52 and rigidly carries the substanceholder guard 55, 56. The tube 59 is axially immovable and the sleeve 75 non-rotatable by reason of pin-and-slot engagement 84, 85 with the rod 76. The slice-receiver guard 60, 61 is revolubly mounted on the tube 59. The sleeve 75 is movable to the right to stop the drive either by a handle 73a or by a rod 80, which is spring-pressed to the left and has a pin 91 engaging a slot 92 in the tube 59 and an open-ended slot 93 in the sleeve 75. When the rod 80 is moved to the right, a second pin 90 thereon, also projecting through a slot 65 in the tube 59, moves out of a slot 64 in the pivoteye 63 of the guard 60, opening of which obstructs return of the rod 80 and sleeve 75. Movement of the handle 73a to the right brings the slot 93 clear of the pin 91 and permits the tube 59 to rotate, carrying with it the guards 55, 60 and obstructing return of the sleeve 75. This form of the invention is applicable also to clutch &c. drives.

Fig. 4 shows in plan a stationary front mirror 11 and a rear mirror 14 pivoted medially about a vertical axis and oscillated by a pitman 20 connected to a rotating disc 18. The mirror 14 may oscillate about a horizontal axis, or both mirrors may be given an independent or a concurrent movement. In another form, the rear mirror is mounted on gimbals and given a swash-plate motion. Alternatively, one or both mirrors are swung to and fro, and their approach and recession may be utilized to produce a draught of air to cool the lamps and motor. The display matter may be on, or cut out of, the mirrors, or may be located in front of the forward mirror. In another form, an image is optically-projected on to the front mirror. The display matter may comprise the numerals of a clock dial, the mirrors being perforated to allow the hand shafts to pass through. With an electric clock, the clock motor may effect movement of the mirrors.
