Abstract: 368,925. Heating water and other liquids. ROSENBLAD, C., 3, Karlavõgen, Stockholm. Jan. 27, 1931, No. 2702. Convention date, Jan. 27, 1930. [Class 64 (i).] Impure hot vapours or gases are used to heat pure water or other fluid by injecting water or other cooling liquid into the vapour or gases in quantities so controlled that the temperature of the cooling liquid is raised to just below boiling point, the liquid being then passed through a surface heat exchanger to heat the pure water or other fluid. Cooling water is injected under the control of a valve 32 in the supply pipe 5 through nozzles 6 into exhaust steam or vapour discharging through perforations in a pipe 1 into a vessel 2. The valve is operated by a thermostat 33 in the hot-water outlet pipe 8a of the vessel 2. The outlet pipe opens into an accumulator 9, from which hot water is taken through a pipe 15 to a heat exchanger 21 to heat pure water supplied by a pump 26. After passing through the heat exchanger, the impure liquid collects in a tank 25 from which it is drawn by a pump 31 for injection into further quantities of exhaust steam. Water may flow from the tank to heat incoming pure water in a heat exchanger 40. Steam may pass from the pipe 1 through a pipe 13 passing through the accumulator and leading directly into the vessel 2. Excess steam passes from the accumulator into the vessel 2 through a pipe 12.

Abstract: 1358794 Bag-emptying machine S M THOMAS and E G HINGSTON 18 Jan 1973 [21 Jan 1972] 2884/72 Heading B8C A machine for emptying bags 1 containing particulate, or powdered, material, comprises a shoot 5, down which each bag moves under its own weight, a fixed, upstanding, blade 6, located in the centre of the shoot 5 and extending in the direction of travel of the bags so as to slit each bag open as it passes over the blade 5, a bag-receiving station 7 for receiving the bags leaving the shoot 5, and which have been slit open by the blade 6, and a space beneath the blade into which material from the open bag falls. As shown, 1 or 2 cwt. plastics, or paper, bags 1 containing bulk material such as chemical fertilizer, animal feed, cement, &c. are fed singly, in succession, to a feeding station 2, either by hand, or by a conveyer 3, each bag falling lengthwise down a roller -ramp 4 and on to the inclined shoot 5, which comprises two slightly-spaced, upwardly inclined, guide plates 5a which are arranged symmetrically, on opposite sides of the vertical blade 6. The latter has an upper edge curved downwardly from its highest end, which is approximately level with the lower end of the ramp 4. As a bag falls on to the shoot 5 it is split by the blade so that the contents of the bag immediately begin to spill out and fall through the space between the plates 5a and on to a loading conveyer 13, the momentum of the bag carrying it on to a shaker conveyer 7 in the form of a "straw walker". The latter comprises a number of foraminous members 8 which execute substantially circular, out of phase, motions and have upstanding teeth 10 and projections 10<SP>1</SP> for advancing the bag in the direction of the arrow A while shaking and thoroughly emptying it. The emptied material passes the holes in, and along the inclined bottom walls of, the members 8 to fall on to the loading conveyer 13, baffles 15 being provided to guide the material on to the conveyer 13. The latter may be replaced by a hopper, alternatively the machine may be made high enough to accept a lorry for direct loading. One, or more, upwardy projecting bent tongues 14 may be provided at the lower end of the shoot 5 to slow down the fall of the bags. The empty bags may be collected, at the end of the shaker conveyer 7, by a skip or baler, packer, and the machine may include a bag counter.

Abstract: 484,941. Sealing. ELLIS, C. T. Feb. 2, 1937, No. 3020. [Class] 146 (ii)] In machines for sealing the overlapping ends of metal bands as described in Specification 448,926, in which tongues are punched out and bent over on the underside of the band and a cutter for the free end of the band acts to punch out further tongues, means are provided also to turn over these tongues. The band is gripped between serrated surfaces 82, 83, Fig. 1, brought into engagement by pressing backwards the handle 27 actuating the cutter, and the band is tensioned by a known form of apparatus 90. A handle 24 is drawn forwards to depress a plate 29 carrying punches 30, Figs. 3 and 5, to punch tongues from the overlapped ends of the band. The handle 24 is then moved backwards beyond normal position to move forward a slide 36 to which is pivoted a plate 40 having at the front end teeth 41 spaced apart a distance equal to that between the punches. A pin 42 on the machine engages a cam surface 43 on the plate and causes the plate to rock to bend the tongues over in the same direction. On the return of the handle 24 to normal position, surfaces 44, 45 restore the plate 40. Punches 46 on the plate 29 form longitudinal tongues in the ends of the band. The handle 27 is then pulled forwards, and a cutter 63, co-operating with the resilientlymounted part 82 of the gripper, severs the free end of the band, and a punch 64, Figs. 5 and 7, on the cutter punches triangular tongues from the band. On the movement of the handle 27 to rear position, a slide 68 is moved forward so that the front end of a plate 70, pivoted to the slide, engages the tongues and, due to a pin-and-slot connection 72, 73 swings the plate to cause the tongues to be bent over in the opposite direction from that of the tongues formed by the punches 30.
