Abstract: 796,339. Steam boilers without internal flues. VAPOR VESSELS. Ltd. July 6, 1956 [April 6, 1955], No. 10151/55. Class 123(2) A steam boiler comprises a vertically disposed cylindrical water container 1, an outer insulated shell 2 supported in spaced relation to the container so as to define an annular passage 4 between the shell and the container wall which is open at both ends and means for supporting a gas burner beneath the container for heating the container. The container has a flanged top 1a with a bolted-on cover plate 3. The upper end of the passage 4 communicates with the atmosphere through ring of openings 8. The boiler assembly is mounted on a hollow stand 9 resting on an asbestos plate 10, the gas burner being supported within the hollow stand. The stand em bodies an integral gas conduit 12. Gas is supplied to the burner through a pressure governor 14 and a regulating valve which controls the gas supply in accordance with variations in steam pressure. Safe lighting procedure and protection against flame failure is provided by an ignition and combustion device 22. To start up the boiler, the pilot jet 24 is ignited through an aperture 25, and after allowing a short period for the thermocouple 23 to warm up, the gas valve is set manually to the open position, thereby admitting gas to the burner, the gas valve being retained in position by an electro-magnet which is energized by current generated by the thermocouple. If the water in the container falls below a predetermined level, a plug 27 in a fitting 26 disposed at that level melts and steam flows through a pipe 28 to extinguish the pilot jet 24, a return spring closing the gas valve as the electromagnet becomes de-energized. A pump is provided for charging the container which is fitted with a water gauge 30. Steam is delivered from the container 1 through a drying coil 32 to the point of use.

Filed: 1965-03-10
Abstract: In a shoe having a sole which is formed and connected to the upper and insole by injection moulding, the outer sole (17) (Fig. 3, not shown) is formed of a material, part or all of which is foamed, and an edge strip 18 of firm homogenous unfoamed elastic material is injection-moulded on to the upper and outsole to extend around the sole and connecting it to the upper.  A last (11) with the upper (12) and insole (15) thereon is arranged on a mould with the bottom plunger (10) raised (Fig. 1), and the edge strip (18) formed by injection moulding.  A middle sole (16) of felt &c. may be assembled within the margin of the insole to limit the dimension of the edge strip, or the latter may be moulded integrally with a middle sole. Plunger (10) is then lowered (Fig. 2) and the outsole material, including an inflating medium, is injected through channel (21). After a short time, to allow an abrasion resistant layer (22) to form, the plunger is lowered further (Fig. 3) when the outer sole becomes foamed.  Alternatively after formation of the edge strip (Fig. 1) the plunger is fully lowered (Fig. 3) and outsole material which is already foamed is injected.  Preferably the outer sole protrudes beyond the lower edge of the edge strip.

Filed: 1924-04-25
Abstract: 237,026. Woosnam, A., (Ederer, L.). April 25, 1924. Electric clocks.-The frame which carries the movement and rewinding magnet L of an electric clock is removably attached to a case by means of hooks and pins A<2>, A<3>, in such a way that placing the frame in position establishes contact between the terminals of the controlling and winding circuits. The terminals H<1>, H<2>, Fig. 6, establish the controlling circuit by way of the frame and one contact and terminals H<3>, H' establish the winding circuit with two co-operating pairs of contact members J', J<2> in the case. The pendulum is energized by the spring E<4> and going train E<5>, D<2>, D', C<12>, C<10>, escapement C' and lever C<6> which is clamped to the arbour of the escapement at C<5> and has a bent part projecting through an opening in the pendulum rod. The controlling circuit is established periodically by a wiper arm F<3> in the time-indicating arbour C" and an adjustable contact G carried by the screwed stud G<5>. The circuit through the electromagnet L then effects the rewinding by the reciprocating armature L<1> and ratchet and pawl E<2>, L<2>. The winding is stopped by contact of the studs E<3>, E<6> on the wheels E<2>, E<5>, which studs carry the ends of the spring. The controlling circuit N', N<3>, N<4>, X, Fig. 7, is closed by the contact F, G, and the relay N<2> is operated which closes the circuit N<14>, N<5>, N<6>, delayed-action relay N', N<26>, X. The switch N<12> is closed by the relay N<7> and the relay N<2> thereby short-circuited by the conductors N<16>, N<6>, N<14>. The operation of the relay N<2> actuates the two relays O<2>, P. The relay O<2> closes the circuit through the relay O<6> by which the heavy-duty switch Q and the bus bar circuits Q<2>, R<3>, are closed to feed secondary clocks and other indicating machines. The switch P' operated by the relay P closes the circuit through the relay U, Fig. 8, which in turn closes the circuit through the minute switch U<1>, U<3>, relay U<7>, U<8>, V<8>, X<15>. The two armed switch U<11> is thereby operated one circuit U<9>, U<5>, U<8>, U<8>, V<2>, X<15> short circuits the minute switch and maintains the relay U<7>, the second circuit U<12>, U<13>, L, U<14> actuates electromagnet L for rewinding. A condenser I is placed across the circuit at U<14>, U<13>, to prevent sparking. The delayed-action relay V closes the switch V<5> after an interval and short circuits the relay U<7> which allows the switches U<11> to reopen.

Title: Multiplexer
IPC: H04L69/14
Filed: 1973-03-02
Abstract: 1429853 Selective signalling EATON CORP 2 March 1973 [6 March 1972] 10330/73 Heading G4H A multiplexer interfacing between a computer and a plurality of transceivers comprises input gates feeding register means feeding output gates, the input gates being connected to receive data from the computer and transceivers and the output gates being connected to past data to the computer and transceivers, a check comparison with a sum of data words being performed in the case of data received from a transceiver. In transfer to a transceiver, an adder (with register) is fed from the output gates to compute a check sum which is appended to the end of the message. In transfer to the computer, the adder computes the check sum for the received message, the sum being compared with a check sum supplied by the transceiver at the end of the message, the computer being notified of the result. In both directions of transfer, an "end of transmission" decoder responsive to the registers following the input gates detects end of message for control purposes, and the computer addresses the required transceiver via a register and decoder (whether the transfer is in response to an interrupt from the transceiver, as in the case of transfer to the computer, or at the computer's initiative, as in the case of transfer to the transceivers). A control unit with respective sequence counters for the two directions is provided in the multiplexer and communicates with computer and transceivers. A counter causes an error stop if 100 words are transferred without an "end of transmission" code being detected.
