Title: Improvements in or relating to electric signalling systems
IPC: H04L25/06
Filed: 1941-05-19
Abstract: 549,453. Automatic exchange systems. STANDARD. TELEPHONES & CABLES, Ltd., BRAY, F. H., and BROWN, L. R. May 19, 1941, No. 6417. [Class 40 (iv)] Selecting impulses are transmitted over a junction in direct-current form as described in Specification 486,764 but are received by a pair of hot or cold cathode gas-filled discharge tubes A, B. These tubes normally pass current and so acquire a temperature that is not substantially changed during .signal reception. When the receiver is seized however, ST pulls up removing a shunt from relay HSA in the main gap circuit of A, breaking the main gap circuit of B and reducing the control-gap voltage of both tubes to a value insufficient to start a discharge. The discharge in A persists however, energizing HSA to prepare an alternative main gap circuit for B. ST also completes the impulsing circuit to the terminating apparatus. At the beginning of each signal impulse tube B receives an impulse at its control gap and becomes conducting, and HSB energizes HSC to break the impulsing circuit to the terminating apparatus and interrupts the main gap circuit of A. HSA then falls and releases HSB by opening the main gap circuit of B. The relapse of HSB is delayed by a condenser discharge and HSC is held subsequently over a back contact of HSA. At the end of the signal impulse, however, A receives an impulse at its control gap and HSA pulls up, releasing HSC to terminate the repeated impulse and preparing the circuit of HSB in the main gap circuit B. The control gaps are given a suitable normal bias from potentiometers connected across the main discharge gap of a third tube C. A method is described by the manipulation of the links shown associated with various test jacks for adjusting the bias centrally to the correct value with the aid of tell-tale lamps which indicate when a discharge is passing in the associated tube.

Title: Improvements in jet propulsion engines including a plurality of intermittently operating combustion chambers
Inventor: BERTIN JEAN HENRI
Filed: 1953-03-10
Abstract: 743,492. Generating combustion products under pressure. SOC. NATIONALE D' ETUDE ET DE CONSTRUCTION DE MOTEURS D'AVIATION. March 10, 1953 [March 11, 1952; March 13,1952], No. 6639/53. Class 51 (1). [Also in Group XXVI] An intermittently operating combustion chamber has on one side a valve or other non-return device and on the other side an ejection tube which is of insufficient length to provide self filling of the chamber, the filling of the chamber being effected by a scavenging device which maintains, during normal operation of the unit, a total air pressure at the entry of the chamber greater than the static pressure at the outlet of the ejection tube. The jet propulsion engine, Fig. 1, has a pulsatory combustion space 1 having an inlet 2 fitted with a non- return valve 2a, which may be of the aerodynamic type as described in Specification 660,144, [Group XXIX], and a convergent ejection nozzle 3. The length of the nozzle 3 is of the order of magnitude of the space 1 and should not exceed 1.0 to 1.5 times this length. Air is supplied to the space 1 by a blower 5 driven by an engine 7 which also drives through a variable speed device 7a a fuel injection pump 4a and an interrupter 8b for the sparking plug 8. The frequency of operation of the combustion chamber and thus the power output may be varied by adjustment of the device 7a. In a modification the blower 5 is dispensed with and the air is supplied to a number of combustion chambers through a diffuser when the chamber is mounted on a vehicle. The combustion chambers may be cooled by air passing through small holes in the end wall of the diffuser. The combustion chambers are enclosed in a fairing having a partition midway along its length in which the inlet valve or valves are mounted. The outlet area of the fairing is engaged so that the pressure drop between the two parts of the fairing is equal to the scavenging pressure required. To enable this arrangement to operate at various forward speeds the outlet of the fairing may be provided with a variable arc or'nozzle. In another modification, the scavenging air is supplied by a pulse jet unit acting in conjunction with a nozzle as an air compressor. When the combustion chambers are used as jet propulsion units the gases may be reheated before passing to the propulsion nozzle by a number of burners 60, Fig. 6, arranged in a circle in the propulsion nozzle 42, and disposed at the centre of conical diffusers 61 canaling the air. Specifications 653,629 and 711,281, [Group XXVI], are referred to.

That part of the pawl 17. engaging the cam 11 is of dovetail shape and engages in a similar shaped recess. That part engaging the cam 13 is of V-shape and engages in a V-shaped recess. Another arm of the pawl has two notches co-operating with a spring loaded pin 19 which retains the pawl in either the operative or inoperative position. The pawl is moved into operative position by finger pressure on a sliding rod 18 whose end is in an inaccessible position on the edge of the door, covered by the staple casing when the door is shut to prevent inadvertent locking. The end is further protected by a thin spring strip 20. In this position, the cam 11 on the inside handle is locked by the dovetailed end of the pawl but the cam on the outside lock may still be turned and will force the pawl into the inoperative position shown. The pawl may be released from the inside by a sliding. bar 21 operable by a button but normally locked by two springs loaded gated tumblers 22 disposed in slots in the bar 21 which are released when the key is inserted in the hole 25. A single spring 24 loads both tumblers and urges the bar 21 outwardly. Specification 618,490 is referredto.

Abstract: 1,215,092. Measuring displacement electrically. RANK ORGANISATION Ltd. Feb. 12, 1968 No.6842/68. Heading G1N. The voltage on, for example, the movable plate P, Fig. 2, of a capacitive potentiometer produced by plates 4, 4<SP>1</SP> (only two are shown) connected to the secondary T 1,2  of a transformer T 1  is cancelled by a voltage produced by a series of tapped casadeconnected transformers T 3  T 4 , whose tap settings at balance are indicative of displacement of the plate P, and which include a zero-offsetting adjustment. The primary of T 1  is fed from A.C. source V 1 , or from a separate source synchronized with V 1 , and tappings 8<SP>1</SP>, 8 on the secondary T 1 , are connected to the primary T 2,1  of a coupling transformer T 2  which drives the decade-tapped transformers. The tapping V of the least significant digit transformer T 5  is earthed, and the total of the voltages between each pair of taps on the decade transformers is applied to the primary T 2 , i at point 10. One tap on each decade transformer is for the zero setting, i.e. producing a null on a meter 3 for any position of the plate P, the positions of the other taps at balance then representing displacement from this position. The taps may be set manually, or automatically by a null-sensing unit (13), Fig. 3 (not shown); or they may be pre-set and the output of a null-sensing unit used to control the plate P. The transformer T 1  may feed the capacitive potentiometer through a correction unit (17) incorporating toroidal transformers (18) in order to match different potentiometers to the apparatus. Inter-connections are made by a selected plug member (16) which selects the measuring scale, nominal feed voltage and amplifier gain (2) for a particular potentiometer; and the toroidal transformers (18) are separately pluggable into the correcton unit (17) to correct for tolerances in a selected potentiometer. An inductive or capacitative pickup may be used in a place of the potentiometer 1.
