Title: Improvements in or relating to contact-less switching circuits
IPC: H04B1/48
Filed: 1966-04-29
Abstract: 1,111,467. Switching circuits; radio signalling. AUTOPHON A.G. 29 April, 1966 [30 April, 1965], No. 18877/66. Headings H3U and H4L. A contact-less circuit for alternatively connecting an aerial A1, A2 to transmitter terminals SA1, SA2 or receiver terminals EE1, EE2, consequent upon the operation of a switch K connecting a D.C. source to the transmitter supply circuits S or to the receiver supply circuits E comprises for the transmitter, a T-seotion C1, C2, L1, the latter element being shunted by a diode D1. The capacitor C3 has a high capacity so that effectively it only serves as a block for D.C. The values of the elements C1, C2, L1 are chosen so that the shunting effect of the relatively low impedances presented across the terminals SA1, SA2 and A1, A2 produces a parallel resonant circuit resonant at the transmitter frequency. Similarly, for the receiver in which the impedance across the terminals EE1, EE2 is low, a T-section C4, C5, L2 is provided resonant at the receiver frequency, and a diode D2 shunts the element L2. When the switch K is in the position shown to supply the receiver, the D.C. flows through E, L1 and D1 to the -ve terminal. Thus D1 is rendered conductive and shortcircuits L1, and C2 presents a high impedance shunt across A1, A2. However, D2 remains blocked and energy can flow from A1, A2 via the resonant T-section to the receiver EE1, EE2. Similarly, when switch K is moved to the transmitter position, D2 becomes conductive, C4 acts as a high impedance shunt, and energy can flow from A1, A2 via the resonant T- section to SA1, SA2.

Abstract: 329,203. Haddan, R., (Crane Packing Co.). June 20, 1929. Tube extractors. -A, device for extracting condenser tubes &c. from tube sheets comprises means whereby the packing may be withdrawn during the initial stage of the extraction. A member 27 is bored to receive a rod 34 on which are mounted members 36 and 39 of pyramid shape adapted to operate on levers 31 pivoted at 32 in recesses 28 in the member 27. The levers 31 are formed with teeth 33 which are forced through the wall of the tube 11 and into the packing 18 when the rod 34 is drawn back, and are withdrawn when the rod is urged forward. This motion is effected by an eccentric 42 working in a groove 41 in an extension 40 of the rod 34, operated by rotation of the pin 43. A sleeve 51 surrounding the member 27 forms an abutment for the wall 10, and is made in two portions, its effective length being adjustable by a screwed collar 55 to vary the throw of the rod 34. An extension 57 of this rod is joined to a piston 58 in a cylinder 26. When the teeth 33 have been forced into engagement with the tube, compressed air &c. is admitted by a valve 59 into the cylinder to force the piston to the right, thus loosening the packing. The piston can now be returned to its first position, and the teeth 33 retracted, when the tube is removable by hand.

Title: Improvements in and relating to petrol pump installations
IPC: F04B49/02
Filed: 1951-08-14
Abstract: 714,855. Dispensing liquids. BECK & CO. (METERS), Ltd., and PHILLIPS, H. E. Aug. 14, 1952 [Aug. 14, 1951], No. 19184/51. Class 116 A petrol pump having a motor-driven pump, a pre-set mechanism, and a clock indicator, has means for automatically switching off the motor at the end of delivery by the pressure in the supply pipe, the motor switch being urged to the "off" position by pressure in the petrol supply line by means independent of the clock mechanism, but being prevented from so moving until completion of the delivery of the pre-set quantity. The valve V is controlled by a lever 46 on a shaft 40. The shaft supports a lever 50, which when the setting disc 22 is pre-set, contacts the edge of the disc and holds the valve open. One end of the lever is in the path of a rod 64, the rod being urged to the right against the action of a spring 62 by the pressure of fluid in delivery pipe P on piston 58. When a predetermined quantity is almost delivered the valve is partially closed, the disc 22 having been rotated by a pawl 28 on an eccentric driven by the meter shaft so that a pin 52 on the lever 50 abuts a slot 54 in the disc but is prevented from entering by a cam follower 50a on the lever which engages a step 66a on a cam on the meter-driven shaft. Further rotation of the shaft causes the cam follower 50a to contact the step 66b to allow the pin 52 to move into the slot 54 and so rotate the shaft 40 and with it lever 46 to close the valve and move the lever 50 from the path of the rod 64 which moves to the right allowing the fluid to escape down the pipe R which forces down a piston to lower a rod against spring action and to open a motor switch. The apparatus can be used with reference to the apparatus described in Specification 645,800 in which the motor is stopped by retraction of the hose and the clock zeroed and the motor switched on by paying out the hose. When the hose is retracted the counterweight pulls on a cable to open the valve and rotates the shaft 40 clockwise so that the pin 52 is removed from the slot 54 allowing the disc 22 to be reset. A lever is rotated which causes the resetting knob to be clutched to the resetting shaft. The lever 50 regains its position to form an abutment for the rod 64
