Title: Electro-mechanical manipulating apparatus for sliding doors
IPC: E06B3/46
Filed: 1963-07-09
Abstract: 1,001,432. Door operating mechanisms. B. KOFYAN. July 9, 1963 [July 24, 1962], No. 27185/63. Heading E2M. Electro-mechanical operating apparatus for sliding door comprises an electric motor mounted on a fixed slide and having a toothed wheel engageable with a chain or rack secured to the door, rotation of said wheel first causing a limited movement of said motor along the slide, which movement caused the door to lift, and then causes the door to slide longitudinally to its open position. As shown a motor 4 is mounted for sliding movement along a bar 6 between end stops 10 and 10<SP>1</SP> and devices a toothed wheel 3 engaging a chain 5 which is carried by and secured to a rail 17, the latter being fixed to the door A. To open the door, the motor is energized to drive wheel 3 in an anticlockwise manner, and, due to the inertia of the door A, the motor 4 moves to the left along bar 6. During this movement a cam depending from the motor strikes a projection 1a of a lever assembly 1, rotation of which is transmitted via links 7 and 7<SP>1</SP>, levers 12, 12<SP>1</SP> and 12<SP>2</SP> and a shaft 14 to a shaft 25. Eccentrics (Fig. 6, not shown) as secured to the latter in such a manner as to raise the door when the shaft is rotated. Since the bottom edge of the door is no longer in contact with its frame the door is moved to its open position where it operates a switch to de-energize motor 4. At the completion of the sliding movement of the motor 4, i.e. when the motor abuts stop 10<SP>1</SP>, a spring-loaded lever 8 which was previously been held under stop 10 rotates so that the end 8<SP>3</SP> of the lever engages the inside face of the stop 10, thus retaining the motor in position. To close the door motor 4 is re-energized to drive wheel 3 in a clockwise direction. As the door approaches its closed position a plate 11 on which the lever assembly 1 is mounted strikes the end 8<SP>2</SP> of the lever 8 so that the opposite end of the lever is rotated out of engagement with stop 10 and the motor is free to move along slide 6. During this return movement the cam 2 strikes a further projection 1c of the lever assembly 1 which rotates to lower the door. A further dooroperated switch is provided to de-energise the motor when the door reaches its closed position. Manual operation of the door may be effected by pivoting a roller 16, which is pivotally mounted on the motor assembly, out of engagement with the underside of rail 17 so that the motor 4 pivots about the slide bar 6 and the wheel 3 disengages from chain 6 (Fig. 5, not shown). A lever M is provided for manually raising and lowering the door.

Title: Improved method for the production of barium oxide and/or hydroxide
IPC: C01F11/06
Filed: 1925-10-30
Abstract: 259,395. Hill, B. P., and Blaydon Manure & Alkali Co. (1877), Ltd. Oct. 30, 1925. Barium oxide and hydroxide are obtained from barium carbonate by distributing the finely divided carbonate throughout a very hot gaseous phase. The carbonate may be blown into a furnace into the path of the gaseous products of combustion of pulverized coal, crude oil, or gas; or it may be introduced in admixture with pulverized coal; or it may be carried into the combustion chamber by the air blast feeding a fuel burner; or it may be allowed to fall through a rising flame from the fuel. The semi-fuzed residual product, which may contain some barium hydroxide in addition to barium oxide and fuel ash, is collected in a dust chamber or by means of a cyclone separator or an electrostatic precipitator. On extracting with hot water a solution of barium hydroxide is obtained, from which crystals of the hydroxide may be formed. The reaction furnace may comprise a vertical or horizontal combustion chamber, and recuperators or regenerators may be provided to preheat the air necessary for combustion of the fuel.

The machine for applying reinforcing tape to articles described in the parent Specification is modified to operate on workpieces having a bulged portion, specifically the back seam of a shoe upper. The machine is constructed substantially as described in the parent specification, the workpiece being placed over an aperture in a support 10 for the application of the tape to the underside thereof by pressing means 14 and a backing member 16. The latter comprises a shaped block held by a spring poppet 94 in forked arms 82 of a bell-crank lever pivoted at 86, Fig. 1, the other arm 84 being connected by a resilient toggle 98, 100 to a shaft 102 on which is a lever 106 connected by an eccentric pin 108 and link 110 to a treadle rod 112. A spring 116 normally holds the lever 106 and hence the block 16 raised to allow introduction of the work, the arrangement being such that, on depression of the treadle, the block 16 is lowered to an operative portion before the rod 112 trips the clutch 122 to start a cycle of operations which is the same as that described in the parent Specification. The pressing member 14, Fig. 3, similarly mounted to that of the parent Specification comprises a block 50 and an auxiliary block 62 supported thereon by a spring 68 so that the upper face is shaped complementary to the backing member 16 to receive a back seam of a shoe and to exert equal pressure on all parts thereof regardless of their thickness. Cam means 132, Fig. 1, is also provided on the clutch 122 to ensure that only a single operating cycle is performed for each depression of the treadle. The tape feed jaws are modified to bow the tape transversely and thus give a more reliable feed, and a lever 142, Fig. 1, is provided to open them to facilitate threading the tape therethrough.

The heat sealing and cutting head 74 comprises a roller having a plurality of equally spaced resistance heating wires 76 each mounted on an insulating block 78 and connected at each end to a terminal ring (84) contacting a stationary carbon ring (84a) and brass ring (84b) connected to a source of electrical energy through a wire (85). Bags of different widths may be produced by de-energizing some of the heating wires 76, by varying the speed of the impression roller 92 relative to that of the head 74, or by changing the head 74 for one of a different diameter. To accommodate bags of different widths, the longitudinal position of the group of rollers 134, 126 in the machine may be adjusted. The connecting nips are formed by knobs (88) on the blocks 78 adjacent each heating wire 76 which co-operate with grooves (94) in the impression roller 92 to form sealed but uncut portions. An electric eye (188) may be utilized to detect printed indicia on the web 180 and control the speed of the impression roller 92 so that the indicia are not cut by the heat seals. In modifications, the connecting nips are formed by spring fingers (194) or rings (204) on a masking roller (202) co-operating with the grooves 94 in the impression roller 92.
