Title: Method and apparatus for heat treating tobacco
IPC: A24B3/04
Filed: 1958-07-22
Abstract: 871,758. Rotary drum driers. KORBER, K. July 22, 1958 [July 23, 1957; June 6, 1958], No. 23499/58. Addition to 831,748 Class 34(2) The variable additional heating effect of the invention claimed in the parent Specification comprises a substantially constant flow of hot air through the container or drum, only the temperature of which is controlled according to the moisture content of the tobacco. As shown a fan 1, Fig. 1, forces the desired amount of air through a heating device 3 for supply to the rotating drum (not shown) via a pipe 4. The device 3 comprises component heaters 3a, 3b, 3c, arranged for parallel, Fig. 2, or series, Fig. 3, air flow. Flow through the heater 3a is unhindered but alternative or subsequent flow through heaters 3b, 3c, depends upon the amount of heat desired control being effected by valves 5, 6, so that the amount of air passing into the pipe 4, remains substantially constant. Variations in the amount of air flow according to the air resistance offered by one or more heaters may be compensated by adjustment of a regulating valve 7' which may also serve as one of the control valves used in the parent for controlling the hot air.

Title: Improvements in steam boiler installations
IPC: F22D3/04
Filed: 1923-09-20
Abstract: 226,592. M³ller, P. H. Sept. 20, 1923. Fluid-actuated valves. -In a boiler installation fitted with a feed-water accumulator in which the feed water is preheated to evaporation temperature by boiler steam, the admission of water to the accumulator is so controlled in accordance with the boiler pressure that the supply of water is increased as the boiler pressure rises and is decreased as the boiler pressure falls. Water is supplied to the boilers from, the accumulator through automatically-operated feed valves in accordance with the rate at which water evaporates in the boilers. The supply of water to the accumulator is further controlled by a float or like device which stops the supply when the accumulator is full and opens the supply when the accumulator is empty. An accumulator c is supplied with water through a regulator p. A valve q, Fig. 2, in the regulator is operated by a spring-loaded piston 8 acted upon by the steam pressure. Further, valves 12, 13 in the regulator are so operated by a float 10 in the accumulator that at the maximum water level the valve 12 is closed and the water supply through the regulator stopped, and at the minimum level the valve 13 is opened and a water supply is maintained even if the valve 9 is closed. In a modification, the supply valve 9, Fig. 3, is operated by a piston 8 in a cylinder containing oil floating on a layer of water which is acted upon by the steam pressure communicated through a tube 43 which opens into the cylinder through a port in a cock 15. The cock is kept in its central position as long as the water level in the accumulator does not reach its upper or lower limits. At the limits, a float operates a switch so controlling a magnet as to close the tube 43 and place the cylinder in communication either with a tube 23 open to the atmosphere or the suction side of the feed pump or with a tube 26 open to the pressure side of the feed' pump. The valve 9 is thus maintained closed or opened, until the water level again falls or rises. In a further modification, the float 10 in the accumulator rotates a slotted plate 34, Fig. 7, so connected to the slide valve 35 of a piston device that the piston 31 is moved up or down as the float approaches its lower or upper limit, thus opening or closing the supply valve 9. In the intermediate levels of the float, the piston 31 is in its central position and the supply valve is operated by the piston 8 acted upon by the steam pressure.

Abstract: 839,333. Making heat exchangers; stamping; punching. KRITZER, R. W. July 29, 1957, No. 23941/57 Classes 83(2) and 83 (4). [Also in Group XIII] In a method of making heat transfer units; e.g. airconditionershaving tubing, e.g. of copper and fins, e.g. of aluminium, a continuous web of fin-stock 20, Fig. 1, is formed with openings 21 surrounded by flanges 23 and the stock bent transversely to align the openings and flanges in longitudinal zones to form fins serially connected at alternately opposite ends the longitudinal zones being severed from the stock and constituting strips into which tubing is inserted. Gangs of tools mounted on a head b and a bed a, Figs. 9, 10, operate on longitudinal zones of aluminium fin-stock 20 which is supplied from a reel. The gangs act simultaneously one to each longitudinal zone or strip and the stock is advanced step-by-step so that tools 42, 44 act together to reverse and perforate the bulges 37; 40, Fig. -12, previously formed by the tools 35, 38, after which the punches 49; 51 simultaneously act to form flanges 23a prior to the final formations of flanges 23 by the tools 56, 57. Perforations 25 are formed by the punches 62 acting simultaneously with tools 42, 44. Dies 70, 74 and knives 90, Fig. 14 (not shown) act simultaneously with tools 56, 57 to form, respectively, turbulence ribs 24 and slits 26 between the longitudinal zones, which remain connected by tabs 26a. The stock is stripped from the lower press tools after each step by spring-loaded plungers 68. The strips are finally bent trans- .versely to form an interconnected fin system, Fig. 17, the slits 26 extending substantially through the fins, adjacent zones or strips being attached only by the tabs 26a which are severed as required to separate a single strip or a group of strips from the bent stock. By inserting and expanding tubes in the aligned openings 21 heat transfer units of various tube arrangements are formed, the number of strips severed from the stock and the position of the transverse bends in the stock being varied to suit the particular unit required.
