Title: Improvements in or relating to vehicle drum brakes
IPC: F16D65/22
Filed: 1965-02-03
Abstract: 1,100,221. Hydraulic operation of drum brakes. FRANCAISE DU FERODO SOC. ANON. 3 Feb., 1965 [10 Feb., 1964], No. 4755/65. Headings F2E and F2F. An hydraulically operated internal shoe drum brake is arranged to provide two phases of braking, an initial phase of high effectiveness in which the hydraulic actuating means tends to cause both shoes to move in the same direction as the drum and a subsequent phase of moderate effectiveness in which the actuating means tends to cause the shoes to rotate in the opposite direction, that is with a self-releasing action. The actuator comprises a cylinder 26 provided with two pistons 31, 41 defining a pressure space 44. Piston 31 engages one end of a shoe 27, the piston 41 acting through a resilient device 32, 48, 52 on to the end of the other shoe 28. The device comprises a prestressed spring 52 disposed between flanges on an end member 32 and a sleeve 48, respectively, the sleeve being slidable, between stops, on the member 32. At moderate hydraulic pressures the weaker return spring 53a is overcome to allow piston 31 to move leftward and apply shoe 27 to the drum, the shoe 28 being applied by duo servo action to abut the member 32. At higher pressures spring 52 begins to yield and piston 41 also moves leftwards until the collar 37 of piston 31 abuts the ring 40. Further pressure increase now causes piston 41 to move backwards and apply the brakes against the direction of rotation of the drum, i.e. with the shoes acting as trailing shoes. In other embodiments two cylinders 26 are provided giving two leading shoe action at low actuation pressures. The springs 52 may then be set at the same or different pre-compressions. The pistons 31, 41 may be of different diameters. The Specification also shows a master cylinder circuit for the brakes; a pressure limit and/or a pressure reducer (Fig. 11, 12, not shown) may be provided.

Title: Improvements relating to information exchange systems
Inventor: WHITE ERIC LAWRENCE CASLING
IPC: G01S13/937
Filed: 1956-02-15
Abstract: 888,361. Radio-frequency systems; radar. ELECTRIC & MUSICAL INDUSTRIES Ltd. Feb. 15, 1957 [Feb. 15, 1956], No. 4799/56. Classes 40(5) and 40(7). A communication system comprises a radar transmitter having means for emitting repetitive radar pulses in different directions in sequence, wherein means are provided for modulating the radar pulses so as to convey a message to suitable receivers, the message being confined to radar pulses which can be received from one direction. The system may be used to transmit from one ship to another information about the position of a target. If the radar has a 2 degree beam rotating at 24 r.p.m. and transmits 2,000 pulses/sec., a group of 28 pulses will be received at any bearing at intervals of 2¢ seconds. A message is transmitted as a group of 11 pulses, Fig. 1, of which the odd ones scan regularly and the even ones are time modulated. Pulse 2 is the synchronizing pulse and is displaced the maximum amount, or alternatively it may be omitted. Pulse 4 indicates the sending ship and may have any one of eight positions. The sixth pulse may have four positions to indicate one of three scales for position coordinates or bearing only. The eighth and tenth pulses transmit N-S and E-W coordinates in analogue fashion. Fig. 2 shows a receiver, which is inoperative until a synchronizing pulse is recognised by unit 16 and used to reset binary counters 17, 18 and ring counter 25. The next pulse received, number 3, initiates in decoder 14 a sawtooth wave 26, Fig. 3, which is reversed by pulse 4 and arrested by pulse 5; the potential 27 which represents the signal is fed through gates 19 and 21 to the appropriate channel, gate 19 being opened by counter 18 and gate 21 of counter 25. Decoder 15 similarly decodes the sixth pulse, and so on alternately until the whole message has been decoded. As an alternative binary coding may be used; this requires eight pulses for each co-ordinate, but it may be unnecessary to leave alternate pulses unmodulated. In another alternative the position is represented by three co-ordinates sin #, cos # and I/R. Some protection from jamming once a synchronizing pulse has been recognised can be achieved by arranging a gate which only admits pulses during the expected maximum range of time displacement. Pulse width modulation may be used instead of time modulation.

Title: A method of converting the phase angle of an electrical signal into a frequency or conversely, and a circuit arrangement for performing the same
IPC: H03L7/00
Filed: 1966-02-04
Abstract: 1,131,211. Photo-electric distance measuring. AGA A.B. 4 Feb., 1966 [5 March, 1965], No. 4961/66. Heading H4D. A signal phase is converted into a frequency (or conversely) by controlling the frequency of an oscillator with the output of a phase detector, the inputs to the phase detector being the signal and the time-delayed output of the oscillator or an oscillation derived therefrom. As applied to an echo distance-measuring system utilizing a light beam modulated at an angular frequency (# 1 , the echo signal (# 1 t+#), where the phase # corresponds to target range, is fed as one input to a phase detector 88 the output from which controls the angular frequency # 2  of an oscillator 85 an output is mixed with oscillation # 1  to afford a signal (# 1 - # 2 )t. The latter is fed via a digital non-dispersive delay circuit 87 (Fig. 7, not shown) of delay T to a further mixer 86 the output {# 1 t + (# 1  - # 2 )T} from which is the second input to detector 88. The angular frequency (# 1  - # 2 ) is measured to give #. Since most communication networks conserve frequency better than phase, remote measurement of frequency (# 1 - # 2 ) is advantageous. The invention is also applied to measuring (non-photoelectrically) the angular position of a rotor, Fig. 5 (not shown).

The tension in a moving web of material is determined by passing the web over a guide roller rotatable on a shaft 11 (Fig. 4) Figs. 1, 2 (not shown) which is fixedly supported at each end and has a reduced cross-section portion carrying resistance strain gauges 30, 31 at a part of its length, whereat the shaft flexes due to force applied normal to its axis by an amount corresponding to the web tension. In the Fig. 4 embodiment there is a reduced cross-section strain member 40 at one end of the shaft 11. To accommodate change in length of the shaft 11 due to thermal expansion or contraction which might cause displacement of the member 40, the shaft 11 is attached to the outer rim of a steel diaphragm 58 the central area of which is secured to one end of the strain member 40. Deflection of the shaft 11 normal to its axis will be communicated through the plane of the diaphragm to the strain member 40 the other end of which is fixed cantilever fashion to a stationary frame member 19. The strain gauges 30, 31 may be connected in the arms of a Wheatstone bridge, the output of which indicates the web tension. The strain member 40 may be adjustably rotatable about the shaft axis whereby it can be aligned according to the direction of the applied force in order to obtain maximum sensitivity of measurement Fig. 6 (not shown). There may be a strain member at each end of the shaft.
