Title: Improvements in methods of and apparatus for the thermostatic control of internal combustion engines
IPC: F02D9/00
Filed: 1931-09-18
Abstract: 389,526. Controlling carburetters, ignition, &c. JENSEN, C. A., 77, Chancery Lane, London.-(Pratt & Whitney Aircraft Co. ; 400, South Main Street, East Hartford, Connecticut, U.S.A.) Sept. 18. 1931, No. 26211. [Classes 7 (iii), 7 (iv), and 7 (vi).] A thermostatic control of the ignition timing, the throttle valve, or the richness of the mixture is arranged to be ineffective at normal temperatures, but to come into action when a critical temperature is reached so as to prevent overheating of the engine. The thermostat may comprise a bimetallic strip 1 secured at 2 adjacent the cylinder head and connected at 4 to a rod 5 adjustably connected to a sleeve 11 slidably engaging a rod 12 connected by an arm 13, for example to the throttle valve. When the temperature becomes too great, the curvature of the strip 1 is sufficient to cause the sleeve 11 to engage the end of the rod 12 to close the throttle. The arm 13 is part of a bell crank which is connected to a sleeve 14 sliding between stops 16, 17 on the hand control rod 15 against the action of a spring 18. In a modification applied to a V-engine, the strip 1 has pin-and-slot engagement with an adjustable rod connected to the ignition-timing levers of each cylinder. In another form, the strip is connected to both throttle and ignition controls; or the strip may actuate an auxiliary throttle arranged between the main throttle and the engine. Fig. 11 shows the strip 1 connected by an adjustable rod 62 to a lever 65 actuating a fuel-control valve 68 against the action of a spring 69. Fig. 8 shows an electromagnetic device 38 which may actuate the control directly by means of a rod 39, or through a relay. The strip 1 moves a contact 34 over a resistance 35 in a circuit containing the magnet and a battery 37.

Title: Reciprocating device, in particular for paint spraying devices
Inventor: HENKE ERICH
IPC: F15B21/02
Filed: 1970-06-01
Abstract: 1294505 Hydraulic reciprocating motors E HENKE 1 June 1970 [6 June 1969] 26249/70 Heading F1A A cylinder 5 is reciprocable over a fixed piston 3 by liquid alternately supplied to chambers 6,7 by a reversing valve 9, the valve 9 being pneumatically operated in response to the pressure in an air line 32 connected to a chamber 43 having a bleed 45 to atmosphere, which bleed is variable in area in dependence on the cylinder's position. The bleed is in the form of a tapering groove 45 in the periphery of a rod 44 sealingly movable through the chamber 43 by the cylinder 5. Because of the tapered groove the pressure in the line 32 fluctuates between a maximum and a minimum at opposite ends of the stroke. This pressure is detected by a pressure gauge 22 having a pointer 23 which carries an arcuate vane 31. Nozzles 25, 26 continuously supplied with compressed air from a line 33 are arranged to be alternately closed by the vane 31, whereby one or other of lines 36, 37 is pressurized by air from respective lines 35, 34. Thus pilot valve 10, 11 connected to the lines 36, 37 are changed over, this in turn causing changeover of the reversing valve 9. The angle between the nozzles 25, 26 and the angular disposition thereof may be adjustable to vary the cylinder stroke and range. The pilot valves 10, 11 may control the reversing valve via further pilot valves, Fig.6 (not shown).

Abstract: 1,247,620. Transferring document carriers between endless conveyers. ORGANISATION RALFS K.G. 1 June, 1970 [31 May, 1969], No. 26251/70. Heading B8A. In a belt conveyer installation for the vertical transport of document carriers 13 held between simultaneously moving runs of two or more endless conveyer belts 11, the carriers being provided with destinationindicators which initiate control pulses to control the routing of the carriers, the conveyer comprises partstretches T1, T2, (T3), (Fig. 1, not shown) in both directions which have between them controlled transfer devices 17, 22, for transferring carriers from an upward run (T1) at will either to the following upward run (T2), or to the downward run of the same stretch, or the other way round. As shown, each transfer device comprises switch points 20 facing the upper reversal point of a part-stretch, and forming the start of the upward run of a following partstretch. The switch points consist of a swinging arm with rollers 21, 22, on each end, over which passes an endless belt 23 driven in synchronism with the belt 11. The points 27 are operated on a signal from a device 26 which is responsive to a destination indicator (not shown) on a carrier. This can be nullified by the action of an electric switch 28 when there is a carrier in that downward run. The rising carrier thus proceeds up through another stretch of the conveyer before being deflected downwardly. A member 27 moves into a position to block the entry of the upper stretch when the points are set for deflection of the carrier.

Title: Improvements in or relating to telephone signalling systems
Inventor: WRIGHT ESMOND PHILIP GOODWIN
IPC: H04Q1/45
Filed: 1962-07-10
Abstract: 1,016,273. Automatic exchange systems. STANDARD TELEPHONES & CABLES Ltd. July 5, 1963 [July 10, 1962], No. 26538/62. Heading H4K. In a V.F. signalling system suitable for use over a T.A.S.I. system at least some of the signals include a prefix signalling condition which is maintained until it is acknowledged by the receiver. The invention is described in relation to the tandem connection of a call via two intercontinental links each employing T.A.S.I. systems in which the risk of " freezeout " might result in non-reception of supervisory signals if the latter were all of predetermined duration. Forward transmission.-In the setting up of a call the originating exchange sends a prefix signal P only. Reception at the tandem exchange results in the reversion, a proceed to send signal X. When this is received by the originating register it sends an inter-register signal kp 2  to retain T.A.S.I. association over the link and to cause seizure of a transit register. This signal also indicates that a tandem connection is required. When the transit register is associated it terminates the proceed-to-send signal thereby causing the originating exchange to send sufficient digits to enable the tandem exchange to connect to the second intercontinental link. Intervals between digits are filled by kp 2  signals. When switching is completed a backward proceed to send X signal is sent causing the originating exchange register to transmit a kp 1  signal indicative of the fact that the rest of the digits will be for a terminating call. At the same time the tandem exchange sends forward a prefix signal P and when this is received at the terminating exchange and a register is associated it sends back a proceed to send an X signal which allows the tandem exchange to transmit the kp 1  signal from the originating exchange. When the terminating exchange receives this it associates a terminating register which terminates the backward proceed to send signal which causes the tandem exchange to terminate the backward proceed to send X signal to the originating exchange. The latter then transmits the remaining digits in the same manner as before. Backward answer signal.-The terminating exchange reverts the prefix P which in due course reaches the originating exchange. Also, recognition of this signal at the tandem exchange also causes the latter to maintain this signal, and also causes an acknowledgement signal Y to be reverted to the terminating exchange. This causes the suffix Y to be sent from the terminating exchange to the tandem exchange receipt of this signal terminating the acknowledgement signal. Likewise, when the originating exchange receives the prefix it sends an acknowledgement signal which is maintained until the Y suffix is sent thereto from the tandem exchange.
