Title: Water heater
IPC: F24H1/10
Filed: 1962-10-11
Abstract: 944,197. Heating water by direct contact with hot gases and solids. K. MIYAHARA. Oct. 11, 1962, No. 38581/62. Heading F4K. Water sprinkled over a stack of heat-absorbing material surrounding a cap-like member forming the upper part of a combustion chamber, above a burner assembly, is heated in the stack of heat-absorbing material by direct contact with combustion products which enter the stack from the combustion chamber through apertures in the cap-like member. In a water heater, as shown, Fig. 1, a gas-burner assembly comprising an air blower 51, a gas supply pipe 54, and a mixing chamber 53, is mounted in a cast iron base unit 10 which latter supports a cylindrical sheet metal casing 20 carrying a top cover 30. An internal cylindrical wall 23 in the casing 20 forms the lower part of the combustion chamber and carries the cap-like member 40 of frusto-conical form having slits with outwardly-expanded upper lips to form downward facing apertures 44 for the combustion products. The member 40 is surrounded by a stack 60 of foraminous heatabsorbing material, e.g. silica, pumice, shale, which may include balls formed of sheet metal. Water to be heated passes through a supply pipe 75 in the casing to a sprinkler head 72 supported in the casing on a bar 73, the sprinkled water trickling down through the stack 60, and collecting in an annular trough 24 in the bottom of the casing 20, to be drawn off through a pipe 81. The combustion products leave the heater through an aperture 31 in the top cover 30. An inner sleeve 25 spaced from the container 20 protects the latter from hot combustion products. Alternative forms of the cap-like member 40 may be used, one form having slits with inwardly depressed lower lips to form upward and inward facing apertures. Another cap-member 240, Fig. 7, comprises a series of spaced frusto-conical rings 247 carried on three bars 249 to form annular openings 244. Fig. 9 shows a cap-member 340 comprising a conical top portion 341 below which a cylindrical reticular or foraminous wall is carried. The heat-absorbing material may be supported on a mesh 391. A window device 82, Fig. 1, allows inspection of the flame in the combustion chamber, and a liquid fuel burner may be used in place of the gas burner shown.

The adiponitrile may be that obtained by the reaction of adipic acid with ammonia in the presence of a dehydrating catalyst and may be first distilled to remove the low boiling and highboiling impurities. Hydrogenation to hexamethylene diamine may beeffected in the presence of ammonia and an iron, nickel or cobalt catalyst.

Abstract: 1446631 Regulating I C engine fuel injection ROBERT BOSCH GmbH 17 Aug 1973 [19 Aug 1972] 38938/73 Heading F1B Apparatus for setting the maximum fuel stop or the pivot point of a lever of a centrifugal speed governor for a fuel injection pump comprises a first movable member 13 which is subject to the pressure in the air inlet manifold to position a setting member 49 and a second movable member 35 which is subject to the manifold pressure, an air-pressure which rises in dependence on engine speed or exhaust gas-pressure and in response to increasing pressure causes the position of the setting member to be adjusted to provide increased maximum or actual fuel supply. The apparatus may be used with an exhaust gas turbo-supercharged diesel engine. The spring-biased diaphragm 35 is subjected on opposite sides 36 and 37 to the inlet manifold pressure through pipes 29b and 29a, the pipe 29a communicating with the chamber 43 through a throttle 41 which determines the rate of pressure rise in the chamber. The diaphragms (61, 62), Fig. 2 (not shown), may be connected coaxial to thrust transmitting rods (63, 64), the rods being in abutment. A non-return valve (89) may provide for pressure equalization between the chambers (82, 92) subject to unrestricted and throttled manifold pressure when the pressure falls. One of the rods (63) operates through a crank (67) to position a maximum fuel stop (73) of a fuel injection pump control rod (75). The first diaphragm (61), Fig. 3 (not shown), may be smaller than the second (101) and subject to the throttled manifold pressure. The throttled and unthrottled pressures may act on respective diaphragms (121, 122 and 131, 132) Figs. 5 and 6 (not shown), acting with the first diaphragm to position the member 49.

Abstract: 869,208. Cathode-ray tube circuits. LUCAS, P. M., and GLOESS, P. F. M. Dec. 5, 1958 [Dec. 5, 1957], No. 39312/58. Class 40(7) [Also in Groups XIX and XL(b) ] A spot on a cathode-ray tube screen, used for read-out of information from a photographic data store 17, (Fig. 6), is adjusted to a desired position by focusing it as a line image on a mask 3 so that photocells 40-43 deliver in reflected binary code a signal representing its actual position to a comparator 6, this signal being there converted to true binary code and compared with the binary coded desired address from computor 7, and using the error signal (in a ternary notation code of radix two) to apply a position-correcting voltage to deflector plates 12. Fig. 5 shows in more detail (and Fig. 4, not shown, shows in even greater detail) the comparator 6, consisting of a ternary code coarse number computor 61 which receives at 50 n -50 o  the position number of the spot in reflected binary code, converts it to true binary and substracts it, order by order, from the desired address binary number received at 70 n -70 o . The subtraction is effected without borrows and the result in each binary order appears as a signal on terminal 18, 26 or 20 according as it is + 1, 0, or -1. The representation of the error in this notation is not unique since + 1, -1 or -1, + 1 in orders P + 1, P may be replaced by 0, + 1 or 0, - 1 respectively, and this is effected in the "coarse-to-fine translator" 6<SP>11</SP>, commencing at the highest orders, the result appearing at terminals 60 n -60 o  and 60<SP>1</SP> n -60 <SP>1</SP> o  as a radix-two number consisting of sets of + 1's only and -1's only separated by zeros. The inputs necessary for this translation in order P which takes place in two stages, the first after comparison with stage P+1 and the second after comparison with stage P-1 are the +1 and -1 signals from order P of 6<SP>1</SP> (18p and 20p), the +1 and -1 signals from P+1 after any translation in this higher order (38p and 37p); the O signal from order P+1 of 6<SP>1</SP> (36p) since if this is received no translation in order P is to take place in the first stage, and signals representing "not -1" and "not+1" (34p and 35p) for use in the second stage. The units 6<SP>1</SP> and 6<SP>11</SP> comprise flip-flops (in 6<SP>1</SP>) registering the inputs from 7 and 40-43 (Fig. 6), and "and" and "or" gates for subtracting and translating (Fig. 4, not shown). The error output of 6 is registered in 8 and periodically read out, with each denomination signal weighted according to its value, and the signals integrated at 94 and used to correct the spot position.

An additional air tube 18 disposed transversely of the chamber 34 has air supply slots 18a blowing flames towards the inlet area 63. The outlet 60 is restricted by side walls and turbulence so caused in the waste gases increased by a baffle 64 at the foot of the chimney encourages complete combustion. In a modification, Fig. 6 (not shown), the hearth is traversed by an endless, stainless steel band, which may be replaced by scrapers carried by endless chains, Fig. 7 (not shown). The second embodiment has an upper feed hopper with a motor controlled preheated drum.
