Title: Rail vehicle suspensions
IPC: B61F5/24
Filed: 1981-05-15
Abstract: A railway bogie has a bogie frame (1) supported on primary coil springs (7) from the wheel axles, the superstructure (9) being supported midway along the bogie on secondary coil springs (11) which are less stiff than primary springs (7). The bogie is stabilised in relation to the superstructure (9) by traction links (23) converging downwardly from points on each side of the superstructure towards a common point at rail level, the lower ends of the traction links being connected to a traction bolster (27) extending across and underneath the bogie frame. The traction bolster (27) has an integral cylindrical shaft or pin (25) extending vertically into a bearing (29) in the bogie frame to permit relative rotation between bogie frame and superstructure and compression of the secondary springs (11). Rolling of the superstructure relative to the wheels is, however, resisted by the relatively stiff primary springs (7). The secondary springs (11) are fixedly mounted at one end to the bogie frame and may be fixed or link mounted (as shown) at the other end to the superstructure (9). <IMAGE>

Title: Liquid supply line control circuitry
Inventor: JOHNSTON WILLIAM
IPC: B67D1/12
Filed: 1983-08-04
Abstract: A beer supply circuit comprising beer kegs 1,2 pressurised from a CO2 cylinder 12 incorporates control circuitry for maintaining the pressure in the kegs. This circuitry comprises a pressure switch 16 which controls solenoid operated valve 13. When the pressure in the kegs 1,2 falls, the switch 16 operates to open the valve 13 to permit CO2 flow from cylinder 12 to kegs 1,2 but to prevent further flow when the pressure has once again reached a satisfactory level. A timer may be provided operative to cause a control signal to issue should the solenoid be on for too long a time thus indicating either an empty cylinder or a fault such as a leak. <IMAGE>

Title: Television transmission systems
Inventor: BRENNAND PETER ROBERT
IPC: H04N7/10
Filed: 1983-08-26
Abstract: A wide band frequency modulated DBS signal of the type having time sequential compressed chrominance and luminance (video) components is received by an aerial (1), frequency converted in a down converter (2) and applied to the input (4) of a conversion unit. The conversion unit has a tuner (5), i.f. stage (9, 10) and a frequency demodulator (11) to produce baseband video which is applied after de-emphasis at (12) to a modulator (27) where the video is amplitude modulated onto a vision carrier from an oscillator (28). The modulated carrier is applied through a vestigial sideband filter (29) and an adder (30) to an output (31). Digital data bursts and other additional digital information present in the DBS signal are recovered in a stage (13) and processed in a unit (14) where the data bursts are expanded to occupy the major part of a line period at a bit rate which is an integral sub-multiple of the bit rate for the data bursts in the received DBS signal. The additional digital information is also expanded at the same bit rate and divided into groups, a group being added to the minor part of a line period containing the expanded data burst. The expanded data bursts and the grouped additional information are digitally modulated in a modulator (32) onto a second carrier from an oscillator (33), the modulated second carrier being applied through a bandpass filter (34) and the adder (30) to the output (31). The output (31) is connected to a cable distribution system for which the narrow band signals produced by the conversion unit are suited as such systems cannot cope with high bit-rates. <IMAGE>

Title: Reusable device for making electrical connection
Inventor: CAMERON JOHN K
IPC: H01R13/193
Filed: 1983-09-29
Abstract: A connecting device (10) includes a socket member (12) having at least two tines (18), the tines (18) having an unstrained configuration from which at least one of the tines (10) can be resiliently deformed away from the other tines (18) to define a socket for receiving and holding a substrate, and a band of heat recoverable metal (14) defining a driver member which in its martensitic phase loosely surrounds the tines (18) so that at least one of the tines (18) can be resiliently deformed outwardly when defining the socket member without deforming the driver member (14). The driver member when warmed to a temperature at which the metal is in its austenitic phase, recovers inwardly and exerts a supplementary inward force on the tines (18). In the martensitic phase of the metal, the tines (18) alone hold the substrate within the socket with sufficient force to provide a physical connection.

Title: A magnetically tuned resonant circuit
Inventor: BLIGHT RONALD L
IPC: H01P1/218
Filed: 1983-11-17
Abstract: A magnetically tuned resonant circuit 209 couples r.f. energy between input and output coupling circuits 210, 120 thereof in a first mode of operation and isolates such energy between such coupling circuits in a second mode. Microstrip transmission lines form the coupling circuits 210, 120, each having a pair of planar spaced strip conductor portions adjacent a resonant body 238 of ferrimagnetic material to provide current paths around the body 238. In the presence of an external static magnetic field HDC, a pulse of current is fed around the current path 214c', 214c'' provided by the input coupling circuit microstrip line and provides a pulse magnetic field HDCp in the region of the resonant body 238 which either aids or opposes the external static magnetic field HDC and in response thereto shifts a resonant frequency  omega o of the circuit 209 in accordance with the equation  omega o' =  gamma  (HDC +/- HDCp) where gamma  is the gyromagnetic ratio of the body 238. Alternatively, a coil 326 supported on a dielectric substrate 321 provides the current path, the coil 326 being disposed adjacent the resonant body. A pulse of current fed to the coil 326 provides a pulse magnetic field HDCp, and the resonant frequency is shifted in accordance with the equation  omega o =  gamma  (HDC +/- HDCp). <IMAGE>
