Abstract: 637,510. Refrigerating; tubular heatexchangers. BIANCHI, G. Sept. 30, 1946, No. 29096. Convention date, Dec. 20, 1945. [Classes 29 and 64(iii)] A continuous-cycle absorption system comprises a rectifier B providing a helical path for the vapour from the boiler A, a gas heat-exchanger D including an inner conduit 5, Fig. 3, of star-shaped crosssection providing a large heat exchange surface, and an absorber vessel E consisting of two drums 11, 12 connected by horizontal tubes 13, 14 through which the rich liquor is maintained in movement to continually renew the absorption surface. The rectifier B comprises outer and inner tubes 1, 2 with a spiral 3 in the annular space. From the condenser C the liquid refrigerant passes through a jacket 8 arranged around part of the gas heat exchanger and thence to the evaporator 25 by a pipe 37. Rich gas from the evaporator passes through ducts 33, formed between the outer conduit 4 of the gas heat exchanger and the star-shaped conduit 5, to a pipe 17 leading to the absorber vessel 12. The rich gas also passes through a centre tube 6 of the heat exchanger bent to join the pipe 17, while poor gas from the absorber 29 passes by a pipe 7, ducts 34 between the starshaped conduit 5 and the inner tube 6 of the heat exchanger apertures 36 and a pipe 35 to the evaporator. Liquid condensed in the gas heat exchanger returns by a pipe 10a to the absorber. The inner tube 6 of the heat exchanger may be closed at both ends, all the rich mixture passing through the ducts 33. The drums 11, 12 of the absorber vessel are connected by upper tubes 13 at about the rich liquid level, and lower tubes 14 of smaller diameter, the liquid entering the tank 11 through the pipe 15 causing a circulation of the rich liquid.

Apparatus for heat setting the uppers of lasted shoes S includes a cabinet 2 having a chamber 6 in which the shoes can be subjected to a hot moist atmosphere, a fan 32 which circulates the atmosphere round a closed path including a chamber 6, an outlet duct 38, a source of steam 24 and an inlet duct 28, and a flap 52 which diverts the atmosphere from the closed path when a door in the cabinet is opened. The steam is generated at a boiler 25, is drawn past heaters 30 in the inlet duct 28, passes through the chamber 6 and is returned to the boiler 25 by the fan 32 through outlet duct 38. The cabinet 2 has entry and exit doors 8, 10 which can be raised by air motors 12, 14. At the same time as the doors 8, 10 are opened an air motor 64 turns a crank 60, 58 to move a flap 52 to close the outlet duct 38 and to allow the atmosphere to escape through a duct 54. The escaping atmosphere enters a dispersal chamber 46 having a fan 44 where it is forced through a layer of foam material 48. The shoes are moved through the chamber 6 by a conveyer belt 68 which is advanced intermittently by an air motor 82 acting through a chain 86, sprocket 90 and a free wheel device (not shown). The apparatus has an automatic control circuit which causes the doors 8, 10 to open each time the conveyer 68 is advanced and the shoes remain in the chamber 6 during two dwell periods e.g. two minutes. The atmosphere in the chamber 6 preferably has a temperature of 130‹C. to 135‹C. and a dew-point temperature of 70‹C. to 90‹C.

Title: Improvements in or relating to the removal of hydrogen sulphide from gases
Inventor: MOORE DAVID BECKETT
IPC: C10K1/22
Filed: 1954-10-13
Abstract: 823,366. Gas purifiers. DEMPSTER & SONS Ltd., R. Oct. 13, 1955 [Oct. 13, 1954], No. 29455/54. Class 55 (2). A process for the removal of hydrogen sulphide from gases comprises passing the gas vertically downwards through a continuous column of purifying material containing iron oxide, the material being intermittently or continuously withdrawn from the bottom of the column while fresh material is charged to the top of the column. A vessel 11, Fig. 1, containing the purifying material 10, has an inlet 12 and outlet 13 for the gas and spaced inlets 17, 18, 19 for a gas containing oxygen. The bulk of the hydrogen sulphide in the gas is removed in zone 14 the sulphided material in this zone being subsequently oxidized in the zones 15, 16. The purifying material is removed at 11a. In a modification a tower similar to vessel 11 is provided, the gas passing therefrom to another tower which is not provided with the inlets 17 to 19. In a modification, Fig. 3, the gas enters a tower 20 which has its upper part similar to the vessel 11 the gas leaving at 23a to enter a tower 21 which is not provided with oxygen inlets. About 2% of the gas leaving outlet 25 is recycled through a pipe 41 by means of a fan 42, oxygen or a gas containing oxygen being added before it enters zone 40 at the base of tower 20. The gas passing upwardly through zone 40 mixes with the main gas near the outlet 23a. In a three-tower system the first two towers which may be either in series or in parallel are similar to tower 20, the final tower being in series with the first two being similar to tower 21. The material is removed intermittently from the base of a tower the interval between removal may be from one to five days. The residence time of the purifying material within a tower is of the order of thirty days.

Title: Improvements in data collection systems
IPC: H03K5/00
Filed: 1960-12-30
Abstract: 977,302. Selective signalling systems. GENERAL TIME CORPORATION. Dec. 30,1960 [Dec. 31,1959], No. 29506/64. Divided out of 977,301. Addition to 801, 647. Heading G4H. The invention is concerned with the calling of the central receiver recorder by a remote transmitter which is ready to transmit,and the selection of this transmitter by the central receiver recorder in the data collection system of Specification 977,301. In response to the "ready to transmit" signal over a line common to all transmitters a pair of selector switches at the central receiverrecorder are stepped round. One selector switch applies ground to its successive contacts and the other selector switch supplies a negative voltage to its successive contacts. At the transmitters a location relay is connected to a pair of search conductors, one from each selector group, and is therefore energized when the central selectors reach the corresponding contacts. Energization of the location relay causes a "search inhibit" signal to be transmitted to stop the movement of the selectors. When the central receiver recorder is ready to receive a message, "transmitter hold" signal is transmitted and the selected transmitter is responsive to this signal to start transmission of its message. A further transmitter may be selected in a like manner while the central receiverrecorder is still receiving a message from another transmitter. Specification 960,391 also is referred to.
