Title: Improvements in or relating to means for starting internal-combustion engines
IPC: F02N99/00
Filed: 1920-04-28
Abstract: 165,596. Adams, A. J. April 28, 1920. Spray carburettors.-Starting is facilitated by means of a pump which draws a supply of combustible mixture from the float chamber or the auxiliary nozzle of a carburettor and delivers it to the induction pipe near the inlet valves. In one form, Fig. 1, the pump barrel e is mounted upon the float chamber g of a spray carburettor. The pump piston a is actuated by means of a lever c and draws mixture past a ball valve from the space k above the fuel. The float chamber is fitted with a flange m depending into the fuel and with air inlets n normally covered by a ring q, so that the air drawn in by the pump passes through the fuel. The mixture is expelled through a port r past a valve leading to the induction pipe. In a modification, Fig. 2, the pump is connected to a pipe 16 in order to draw mixture from the auxiliary nozzle 12 of the carburettor. The nozzle is normally in communication with a port 13 near the throttle valve through ports 38 in a valve 34. When the pump piston is actuated, the valve 34 is lifted by suction and the ports 38 are brought into communication with a chamber 39 leading through the pipe 16 to the pump. The air supply to the nozzle 12 is drawn through ports 42, 29 and the space 26 around the nozzle, and the fuel supply from the space 24 communicating through a restricted orifice 23 with a chamber 19 connected with the float chamber by a passage 18. The main fuel nozzle of the carburettor is fed from the space 24 and has an inner nozzle, supplied from a well connected through a passage 18 with the float chamber.

Abstract: 1430322 Standby supply systems CEAG LICHT - UND STROMVERSORGUNGSTECHNIK GmbH 18 March 1974 [21 March 1973] 11824/74 Heading H2H A standby supply system for a load 5 comprises a battery 3 which is connected to the load by a switch 4 when a main supply fails, a charging device 1 for the battery and an overcharge protection system 7, 11 for disconnecting the battery from the charging device by opening a switch 2. In the event of a mains failure, a mains monitor 6 closes a switch 10 and provides one input signal to an "AND" gate 9. A battery discharge monitor 8 provides a second enabling signal to the AND gate provided that the battery is adequately charged. The "AND" gate therfore supplies an output to close the switch 4 so that the load, such as a lighting appliance, is supplied by the battery. When the mains supply is restored the monitor 6 causes a storage circuit 11 to close the switch 2 so that the battery is charged by the device 1 until the battery voltage reaches a predetermined level whereupon a charge monitor 7 causes the circuit 11 to open the switch 2.

Abstract: 649,011. Thermal switches. ELECTRIC & MUSICAL INDUSTRIES, Ltd. April 30, 1948, No. 11835. [Class 38(v)] In a thermostat for controlling an electrical heating device, e.g. a room heater and comprising a heat-responsive means and switch arranged to be operated thereby in response to changes in temperature of the room, the heat-responsive means is additionally heated by the heat generated in the leads connected to the switch, so as to reduce the lag between the temperature of the thermostat and that in the neighbourhood of the heating device. The switch 4, which may be of the kind described in Specification 419,917, is mounted on a centrally pivoted lever 3, the lefthand end of which is held against an adjusting cam 7 by a spring 5. A bimetal strip 10 is mounted by screws 12 on a bracket 13 and its right-hand end engages the switch plunger 11, the strip being adjusted by a screw 14 so that the switch 4 is closed. The switch terminals 20, 21 are connected to main terminals 18, 19 by leads 31 and 32, and 33 respectively, the leads 31 32 preferably being of nickel. The heater is connected to terminals 18, 19 if a large current is needed, and to terminal 19, and a terminal 17, between leads 31, 32, if a smaller current is needed. On distortion of the strip 10 due to the combined heating effect of the room temperature and the leads 31 and 32, or 31 alone, the plunger 11 is depressed and the switch 4 opened.  The thermostat is carried by a bracket having keyhole slots engaged by studs on the base 1.

Title: Method and apparatus for determining co-ordinates
IPC: F41G7/26
Filed: 1964-03-23
Abstract: 1315351 Missile guidance ELTRO GmbH & CO 23 March 1964 [10 May 1963] 12249/64 Heading H4D The invention concerns a method of determining the co-ordinates which an object has in a cross-section of a beam of EM radiation in relation to the axis of the beam. The method is applicable to the control of a flying object being steered along a guiding beam. The beam is produced and transmitted in such a way that any cross-section thereof normal to its axis is an identical projection of the same transmitted image, each component of which providing measurement data corresponding to the coordinates of that component relative to the beam axis. Thus, the co-ordinates of the object in the beam can be evaluated by the object itself from the data. A modulation disc rotating in front of a radiation source produces the image to be projected, components of the image corresponding to values of modulation of the beam and providing the data. In apparatus for performing the method a projector forms a radiation source for image projection. The radiation is bunched and projects the modulation disc, as an image. An optical mirror system projects the image in such a way that each cross-section of the beam contains an identical image. The modulation disc may be circular with transparent slots and opaque webs.  If the flying body deviates from the beam axis, the measurement data in the image components are used to provide control signals which are fed to the steering gear of the body. The optical image projection system may contain infra-red filters to allow steering of the body by infra-red. To prevent the flying body from deviating further from the beam axis as it moves away from the launch site the bunching of the radiation is varied. The invention may also be applied to assist the landing of an aircraft when the latter is steered along the beam axis to the landing strip.

Title: A multiple fluid control valve device for vacuum systems
IPC: F16K11/10
Filed: 1959-04-15
Abstract: 903,155. Valves. TESLA, NARODNI PODNIK. April 15, 1959 [April 18, 1958], No. 12785/59. Class 135. A multiple-way vacuum control valve, for controlling the pumping process in a system of the type comprising an instrument to be evacuated by a diffusion pump backed up by a rotary pump, comprises a piston valve adopted to connect the rotary pump either directly to the instrument to be evacuated or to the low vacuum side of the diffusion pump, a first poppet valve controlling the communication between the diffusion pump and the instrument, and a second poppet valve controlling air admission into the evacuated instrument, these valves being mechanically coupled and operated sequentially by turning a single operating handle. As shown, a valve body 21 has three chambers 22, 23, 24 opening exteriorly of the body of connection respectively to the diffusion pump outlet, the rotary pump inlet and the instrument to be evacuated. A piston valve 47 having spaced ports communicating with each other through an annular chamber 35 in this valve member, is operated by rotation of a handle 31 through a pin and roller 32, 33, working on a sloping guide track 20. Chamber 24 also communicates through a seat member 28 with the diffusion pump inlet. Co-operating with the seat 28 is a poppet valve 37 carrying a shouldered ring 39 which is releasably engaged by a detent 40 on an extension pin 41 of the piston valve. In the position shown, the instrument, e.g. an electron miscroscope at 24 is connected with the rotary pump inlet through the piston valve. On rotation, poppet valve 37 opens to connect the instrument at 24 via seat 28 to the pump diffusion inlet, this pump exhausting into chamber 22 which is now connected with chamber 23 through the piston valve and thence to the rotary pump inlet. Further rotation releases poppet valve 37 to closed position and isolates the instrument from both pumps, and on still further rotation a second poppet valve 46 operated by roller 33 through a pin-and-lever connection 43, 44 opens to connect the instrument with atmosphere to release the vacuum. The second poppet valve 46 may be put out of action by operating a stop pin (not shown).
