Title: Improvements in or relating to liquid fuel supply systems
Inventor: MORLEY FREDERICK WILLIAM WALTO
IPC: B01D35/12
Filed: 1958-04-03
Abstract: 881,002. Filters. ROLLS-ROYCE Ltd. March 12, 1959 [April 3, 1958], No. 10934/58. Class 46. [Also in Group XXVI] A liquid fuel supply system for a gas turbine comprising a fuel filter and downstream of it a unit, e.g. a fuel supply control unit, in which ice formation is liable to cause malfunctioning, has means arranged on sensing of ice formation in the filter, to heat the unit prior to the heating of the filter for de-icing purposes whereby water formed by melting of ice in the filter flows through the unit without freezing therein. Fuel from a tank 16 is delivered by a booster pump 17 into a fuel pipe 18 containing a fuel heater 19 heated by air tapped from the engine compressor 10 by a conduit 20. The air flow is controlled by a valve 21 operated by a solenoid 21a. The fuel leaving the heater 19 normally passes through a valve 29, a main filter 24 high pressure fuel pump 22, control mechanism 25 and shut off cock 26 to the engine. The system also comprises an auxiliary fuel filter 27. When ice clogs the filter 24, the pressure drop across it increases and causes the collapse of the bellows 34 so that switch 35 is closed. This energises the solenoid 21a which opens valve 21 and allows hot air to be supplied to the heater 19. At the same time the motor 31 is operated to rotate cam 30. This allows spring 29b to urge valve member 29a to the left so that fuel is supplied to the control unit 25 through the auxiliary filter 27. After a period of ninety seconds the cam 30 starts to move the valve member 29a to the right so that for about fifteen seconds both filters are fed with heated fuel. Thereafter, fuel is fed to the filter 24 only. During the periods when hot fuel is fed to the filter 24, the ice in the filter is melted and due to the previous heating of the control unit, the resulting water flows through the control mechanism without freezing. The motor 31 also rotates a cam 30a which closes a holding switch 35a for one revolution of the motor. In a modification, Figs. 2 and 3 (not shown), the control unit and filter have control valves and connecting ducting arranged so that in one setting of the valves the heater is arranged between the filter and the control unit and in the second setting, the filter is arranged between the heater and the control unit.

Title: Improvements relating to pre-payment gas meters
IPC: G07F15/00
Filed: 1944-06-08
Abstract: 587,238. Prepayment gas meters. MASON, A. E., and BURMAN, J. C. June 8, 1944, No. 11008. [Class 27] Delivery of gas is stopped when prepayment is exhausted by arresting the drive to the diaphragm slide valves, which thus serve also in place of the usual "auto-valve," the continued limited movement of the diaphragms being absorbed by a resilient coupling in their driving connection, such movement, and the resulting strain, being reduced to a minimum by effecting the arrest in one of the four valve pistons in which a valve is approaching the closed position. In the construction shown, the tangent arm 26, actuated by the usual pair of diaphragms in the lower part of the casing, is secured to a sleeve 40 loose on the crank-shaft 25 which actuates the slide valves 16 and 17 controlling the diaphragms. The resilient coupling is a tension spring 42 connecting an arm 41 on the tangent arm sleeve 40 to an arm 39 on the crank-shaft 25. When prepayment is exhausted the prepayment mechanism rocks a cranked lever 38 so that a pivoted counterweighted element 44 at its free end lies in the track of arm 39 and arrests it when the valve cover 16 is about to close its case port. The diaphragms continue moving a short distance with the valves stationary until the diaphragms act in opposition and, with a small contribution from the spring 42, counterbalance one another at the crank-shaft. The mechanism then comes to rest with the gas cut-off. When a further prepayment is made, lever 38 frees the arm 39, and the spring 42 contracts and restores the normal timed relationship between the valves and diaphragms so that the meter resumes its normal functioning. The Provisional Specification describes also an arrangement with a pair of overlying discs each at the end of a section of the crank-shaft. The discs are coupled by one or more springs, and that on the crank-shaft section driven by the diaphragms is apertured at its edge for engagement by the stop member which arrests the drive. The stop member may be spring-loaded so as to act instantaneously when released at zero credit.

Title: Improvements in belts carrying electrical connectors and in tools for crimping electrical connectors to electrical conductors
IPC: H01R43/045
Filed: 1960-03-29
Abstract: 896,930. Jointing by stamping. AMP Inc. March 29, 1960 [April 10, 1959], No. 11031/60. Class 83 (4). [Also in Group XVII] In a tool for crimping electrical connectors to electrical conductors including a stationary and a reciprocating die, an indexing device driven by the ram rotates a feed cylinder to advance a belt with connectors mounted on it so that connectors are presented one by one to the dies when the dies are open. A composite stationary crimping die 14, 16 is secured to the upper arm of a frame 8 by a bolt 18 and plates 12, 17 and coacts with a further composite die 24, 25 secured to a holder 20 by a bolt 26. The die holder 20 is mounted for reciprocation on a spring-loaded hydraulicallyoperated ram 4. Connectors are fed from a drum, attached to the frame 8, on a belt comprising two strips 80,83 of an organic thermoplastic material, the connectors being held between the strips. The feed is effected by sprocket teeth 36 on a composite cylinder comprising a circular plate 32 a sprocket wheel 34 and a ratchet wheel 38. The cylinder is freely rotatable on a fixed boss 30 and the sprocket teeth engage perforations in the belt. A cam-plate 46 is also freelymounted on the boss 30 and is biased by a spiral spring 62 attached at one end to the boss 30 and at the other to an arm 58 of a bellcrank the other arm 56 of which carries a pawl 57 engaging recesses between the teeth 40 of the ratchet wheel 38. In operation a pin 68 attached to the die-holder 20 first engages an extension 66 on the bell-crank to rotate the latter against the spring 62 and disengage the pawl 57 from the ratchet wheel, the pin 68 then continues its upward movement to engage a cam surface 50 and rotate the cam-plate 46 to the position of Fig. 9, whereupon the pawl 57 engages in the next recess on the ratchet wheel 38 since the pin no longer acts on the extension 66. During this time a spring-loaded pawl 76 engages the ratchet wheel to prevent its rotation. Near the end of the down stroke of the ram the pin 68 engages the arm 70 of the pawl 76 and disengages the latter from the ratchet wheel 38, the spring 62 then rotates the cam-plate 46 and the feed cylinder anti-clockwise until an ear 48 engages the pin 68. To prevent damage to the feed mechanism in the event of operation without a connector between the dies a recess 53 is provided in the cam-plate to avoid clockwise rotation of the ratchet wheel and the pawl 76 is bevelled so that clockwise rotation of the ratchet wheel would disengage it. The connector belt is held down to the cylinder by spring-pressed fingers 88 and a spring 94, the rear edge of the belt running against a plate 28. Crimped connectors are removed from the belt by pulling the conductor.

Title: Improvements in or relating to teleprinter systems
IPC: H04L1/18
Filed: 1958-04-08
Abstract: 841,412. Printing-telegraph systems. SIEMENS & HALSKE A.G. April 8, 1958 [April 4, 1957], No. 11069/58. Class 40(3). In a teleprinter system including a traffic transmitter and a service transmitter at one station, and at another station a traffic receiver and a service receiver, with interconnection between the stations by one or more channels, a device provided at the one station includes a change-over switch for selectively coupling the traffic transmitter and service transmitter to a channel, transmits a number of first idler signals during the period in which the channel is being changed over from the traffic transmitter to the service transmitter and transmits a number of second idler signals during the period in which the channel is being changed over from the service transmitter to the traffic transmitter, and a further device provided at the other station is responsive to the first idler signals to couple the channel to the service receiver and responsive to said second idler signals to couple the channel to the traffic receiver. The system described employs an errordetecting 7-unit code of 4 marks and 3 spaces, and two 7-unit idler signals designated α and #. If a service signal is to be sent in lieu of a normal message from a transmitter TG a manually operated switch (not shown) operates the device TU so that the second idler signal # is transmitted, and with the switch t in the opposite position, the service message is sent from a punched tape transmitter of the device TS. At the receiver the reception of the repeated # signal operates a circuit to switch over at contact t the normal receiver TG to the receiver of the device TS which now accepts the service message. At the end of the service message, the switch of the device TU is operated so that the tape transmitter of the device TS is disconnected, at least three idler signals α are transmitted, and the tape transmitter of the device TG is connected for normal telegraphic traffic. The reception of the successive idler signals α is effective to change over the contact t of the device TU so that the channel of the multiplex receiver MK is now connected to the receiver of the device TG. The change-over switch includes a plurality of relays each providing a delay whereby the first or second idler signals are transmitted at least three times before the switch changes over. In a multiplex system, the service signals may be sent over the associated traffic channel, or over a channel which, at the time, is not carrying telegraph traffic.
