Title: Improvements in or relating to braking means for tractor-trailer vehicles
Inventor: JEFFREY GEORGE ALAN
IPC: B60T11/32
Filed: 1951-06-25
Abstract: 706,567. Tractor-trailer braking systems. CLAYTON DEWANDRE CO., Ltd. May 15, 1952 [June 25, 1951], No. 15045/51. Class 103(1) In a control valve device for application to a tractor-trailer braking system of the kind which is operated by compressed air and wherein two pipe lines connect the brake operating means on the tractor with the brake applying means on the trailer, two valve elements control the passage of compressed air; the first being controlled by a first pressure-responsive device which is operable by air pressure above a pre-determined degree to maintain said first valve element open and thereby allow air to flow through one line to the trailer, and a second valve element being controlled by a second pressure-responsive device which is operable by the air pressure in said trailer line to maintain the second valve element open and thereby allow compressed air to flow through a second line to the trailer, the drop in air pressure caused by a trailer break-away causing the pressureresponsive devices to close the valve elements and thereby seal the tractor braking system. The control valve device consists of a housing a provided with two valve members g and t. The first member g, acting under the influence of a metallic bellows device j and a spring k, controls the passage of compressed air from the tractor reservoir 3 which passes through the emergency line 8 into the port d and the valve chamber f, through the chamber m and outlet e to the trailer emergency line coupling 10. Port n communicates with a cylinder o and the air pressure acts on the piston p, against the resistance of spring q, to open the second valve member t thus allowing compressed air to flow from the tractor brake valve 5, via pipes 11, 12 through port b and chamber s to the port c and thence to the service line to the trailer coupling 14. Cylinder o is sealed from chamber s by a sealing gland v. Compressed air is supplied from compressor 2 through an unloader valve 4 to an air reservoir 3 and connected by a pipe 7 to an emergency line 8 extending between the brake valve 5 and the valve housing a. In addition, the service line 11, from the brake valve to the tractor brake cylinders 6, also supplies compressed air to the housing a through line 12. In the event of a breakage in the trailer service line, spring q is preloaded to a higher degree than spring k allowing air to escape from cylinder o, port n and chamber m so that the valve members g and t are seated so as to seal the tractor braking system. An alternative arrangement is described where the piston p is replaced by a metallic bellows device which expands under air pressure against a spring to unseat the valve member t.

Title: Improvements in or relating to colour television transmission systems
IPC: H04N9/47
Filed: 1963-04-17
Abstract: 1,030,737. Colour television. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. April 17, 1963 [Nov. 9, 1962], No. 15075/63. Heading H4F. In a colour television system utilizing signals of the " Secam " (Registered Trade Mark) type and in which the number of lines per image is odd and two fields are combined into an image by interlacing, the system is arranged so that during each image the same chrominance signal modulates the sub-carrier during odd line periods and the other chrominance signal modulates the sub-carrier during the even line periods. Thus, as illustrated in Figs. 2a and 2b for a 625-line system, the R-Y signal always appear during the odd lines and the B-Y signal during the even lines. The correct sequence is brought about by resetting the transmitter switch which applies the two chrominance signals to the sub-carrier modulator at the end of each image so that the same signal (R-Y) is employed for the last line of one image and the first line of the next succeeding image. Since the field synchronizing pulses, Figs. 3b and 3d, coincide with odd number lines in each field (i.e. the beginning of line 1 in the first field, Fig. 3a, and the middle of line 313 in the second, interlaced field, Fig. 3c) they also coincide with the same chrominance signal (i.e. R-Y). The field synchronizing may therefore be used to control, the setting of the transmitter switch. The switch may comprise a bi-stable trigger circuit, line synchronizing pulses being applied to both elements of the circuit so as to trigger it back and forth at line rate, whilst field synchronizing pulses are applied to only one element so as to set the switch in the R-Y condition, if not already so set, at the onset of each field pulse. The invention permits the corresponding switch at a receiver to operate in the correct phase without recourse to special synchronizing or colour identification signals. The receiver switch is merely controlled in the same manner as that at the transmitter by means of both the received line and field synchronizing signals. The Specification describes a suitable transmitter and receiver with reference to Figs. 4 and 5 (not shown), the arrangements being conventional apart from the switch control as described above.

Abstract: 713,760. Automatic control systems. BRITISH THOMSON-HOUSTON CO., Ltd. June 5, 1952 [June 26, 1951], No. 15144/51. Class 38(4) [Also in Group VIII] In an automatic guide for correcting sidewise displacement of the wire-cloth 2 of a paper-making machine &c., e.g. incorporating induction coil-detectors 7 and a circuit as disclosed in Specification 367,928, [Group XXXVII], the detectors are moved at the same time as the guide-roll axis, so that " hunting " is reduced. The detector 7 is on a bracket 15, allowing adjustment of height, of inclination and of position laterally of the wire-cloth 2, the bracket 15 &c. sliding on rods 13 and being linked by a bell-crank lever 27 and an arm 28 with a sliding bracket 4a supporting a bearing of the guide roll 1. Drift of the wire-cloth 2 towards one side or the other energizes either a solenoid 40 or a solenoid 41 respectively, causing an arm 43 to be moved against spring action at 44 and to bring a pawl 34 or a pawl 33 into engagement with a ratchet-wheel 31, the said pawls being spring-loaded and being continually reciprocated by an eccentric 37 &c. on the shaft of the guide-roll. The ratchet-wheel 31 is thereby moved along a fixed, screwed rod 30, and moves the bracket 4a. Alternatively a rotating lead-screw may be used; also, the detectors may be photo-electric.
