Abstract: 217,453. Morineau, A., and Negrier, P. July 17, 1923. Fluid-actuated valves. -A gas-heated water heater has the gas supply controlled by the movement of the burner and by the flow of water through the heater. The v-ater inlet 1 is divided into three branches a central gilled tube 2 and two coiled tubes 3, 4,. which are joined to a larger coiled tube 5 arranged to leave a large combustion space. The burner supply pipe 32 is fitted with a regulating- valve 32a and is carried by a socket 48 provided with a port 56 and adapted to rotate on the gas valve casing 49. The plug of the gas cock 36- which is held to its seat by a spring 50 has a single port 54 and is fitted with a pivoted catch 51 whereby it may be connected to the burner supply pipe. When the burner is withdrawn from the heater, gas is supplied through ports 54, 52 and 56 to permit a small flame to be ignited. If the catch 51 is then engaged with the recess 53 and the burner replaced ports 54, 55, 56 are brought into agreement so that when water is withdrawn a full gas supply is available. Auxiliary ports 52 are provided to maintain the small flame supply while the burner is being inserted in the heater. When no water is being withdrawn the gas supply is reduced by a valve 37 provided with a leakage port 35. As soon as water is withdrawn, the flow of water acting on a disc 42 against the action of a weight 42a acts through a lever 40 to open the valve 37 againstthe action of a spring 39.

Title: Improvements in processes and apparatus for the carbonization of coal
IPC: C10B53/08
Filed: 1961-05-24
Abstract: An apparatus for carbonizing coal, e.g. briquetted brown coal, comprises means 3 for preheating the coal to between 200 DEG  C. and 300 DEG  C., and a vertical shaft retort 1 in which hot gases are circulated in a plurality of successive heating zones 9 . . . 16, each maintained at a higher temperature than the preceding zone, and means for controlling the gas circulation in each zone whereby the temperature range in each zone may be separately controlled. The apparatus is in four stages:  preheating stage 3, low temperature carbonization (250 DEG C. to 550 DEG C.) stage 4, high temperature carbonization (550 DEG  to 1000 DEG C.) stage 5, and a cooling stage 33, and stages 3 . . . 5 are divided into zones 6 . . . 8, 9 . . . 11, 12 . . . 16 respectively. A gas-tight partition 20 separates the stages 3, 4 and is provided with periodically operated doors.  In a modification, Fig. 2 (not shown), the stages 3, 4 are in separate containers inter-connected <PICT:0947726/C3/1> by a closed conveyer. Temperate control is effected by mixing heated and cooled gases in chambers 22 before delivery to the various zones, the gases being circulated by blowers 40.  In addition, combustion chambers 24, fed with air by a blower 41, are utilized in the higher temperature part of the apparatus, hot gas being delivered at 34 to pass in succession through radiant heaters 17 in stage 5, and to manifolds 27 having outlets 28, Fig. 12, in stage 4.  A condenser 19 is included in the outlets 43 from zone 9, and a heat exchanger 35 in the circuit of the cooling stage 33.  In a second modification, Fig. 3 (not shown), the zone 6 is omitted and the radiant heaters 17 are replaced by manifolds which supply hot gas to the coal, as in stage 4, the zones 12 . . . 16 being compressed into one zone only.  In this embodiment, high temperature carbonization is carried out at 700 DEG  to 850 DEG C.

Title: Improvements relating to automatic electric welding machines
IPC: B23K11/24
Filed: 1934-06-27
Abstract: 436,106. Welding. THORNELOE, A. J., St. Beron, Alderbrook Road, Solihull, Warwickshire. June 27, 1934, No. 18910. [Class 83 (iv)] In a welding-machine having a number of welding-heads for operating on different types of work, each head has independent means for controlling the pressure applied to the electrodes and common means are provided for starting the welding current and stopping it when the weld has been completed, the pressure and current controls being actuated by a series of relays which are interconnected so that when one head is in use, none of the others can be used. As applied to a machine having two heads, the electrodes (not shown), are actuated pneumatically, the air pressure for one head being controlled by a valve 1 and that for the other by a valve 2. The valves 1, 2 are operated electrically by relays R<1>, R<2> which are supplied with low tension current from a transformer 12 whose primary receives high tension current from the mains b. The automatic make-and-break device 8 for the primary of the welding-transformer 10 is operated by air pressure controlled by a valve 7 which is actuated electrically by a low tension relay R<3>. In operation, actuation of a switch on one of the welding-heads by the operator energizes one of the relays R<1>, R<2>, according to which head it is desired to use. The relays R<1>, R<2> are interconnected so that when one is energized, the circuit to the other is broken and hence the second welding-head cannot be operated. If the relay R<1>, e.g. is energized, the valve 1 is operated to admit air to the appropriate head by pipes e<1> and press the electrodes against the work. Further motion of the hand-operated switch energizes the relay R<3> thereby operating the valve 7 to admit air to the controller 8 and start the welding-current. A further relay R<4> maintains the relays R<1>, R<3> in operation if the operator releases the hand switch on the head. When the weld has been completed, the controller 8 cuts off the welding-current and simultaneously releases the valves 1, 7 and de-energizes the relay R<4> so that the machine returns to inoperative position. The air pressure to the welding- heads passes through reducing valves 3 so that the operative pressure on the respective heads may be varied, and a switch 10<a> provides for variation of the welding-voltage.

Abstract: 695,861. Reservoir pens. COMPANIA URUGUAYA DE FOMENTO SOC. ANON. Aug. 13, 1949. [July 15, 1948; July 9, 1949] Nos. 19058/48 and 18218/49. Class 146 (iii)., A cylindrical &c. reservoir 1, Fig. 1, for a ball point pen, attached to a writing extremity 2 having a writing ball 3 therein, is provided with a buoyant sealing member 5 which is a sliding fit in the reservoir, follows the end of the ink column, and prevents escape of ink when the pen is inverted, and a non- buoyant balancing member 6 which sinks to the position shown during writing but, when the pen is inverted, descends through the ink to rest on top of the member 5 thereby preventing any tendency of the latter to rise in the ink and so prevent ink seepage. In the form shown in Fig. 3, the balancing element 6a is buoyant and the sealing member 5a is non-buoyant in the ink, so that in the writing attitude the element 6a will float on top of the ink and support the member 5a, and in the non-writing attitude the element 6a rises through the ink leaving the member 5a at the bottom of the ink column. The element 6a is a bubble of air or other gas in a film of synthetic resin, but it may be a gas bubble not enclosed in a shell, in which case the entry to the feed duct 4 must be small to prevent the air bubble entering it, or a porous filter &c. may be used at the duct entry of the kind described in Specification 650,804. Ink seepage due to capillary creep past the sealing member may be prevented by providing annular sharp-edged grooves in the inner surface of the reservoir near the open end thereof, as described in Specification 695,862. Further leakage preventing means include (i) a plug 7, having an air hole 8 therein, to close the end of the reservoir, which is preferably conically shaped ; and (ii) sharp edges 9 on the sealing members. Examples are given of preferred materials, weights, and dimensions of the various members. The ink preferably has a viscosity of 15 poise at 37 ‹C. Specifications 564,173, 571,698, 573,747, 621,847 and 695,861. also are referred to.
