Abstract: A valve assembly, for use with a tubeless tyre on an alloy vehicle wheel, has an aluminium alloy body 1 with an inner end flange 5 and a stepped shank with a larger diameter section 6 adjoining the flange 5 and a smaller diameter outer end section 7. A sealing member 2 of rubber or like material seats against the flange 5 and closely surrounds the shank section 6. An annular nylon washer 3 also fits over the shank section 6 which is screw-threaded to receive an aluminium alloy sleeve nut 4 with an outer end hexagon section 14 providing spanner flats. The sealing member 2 has a short projecting sleeve section 12 which locates in the valve mounting hole of a wheel rim, the latter being clamped up between the sealing member 2 and the washer 3 by the nut 4. A generally hemispherical sealing face 13 on the member 2 deforms to provide a seal with the rim, and the member 2 has a projecting annular rib which seats in an annular groove in the flange 5 around the shank of the body 1. <IMAGE>

Title: Local loop communication network for routing date and telephone speech signals in digital form
Inventor: DEJEAN JACQUES HENRI
IPC: H04M9/02
Filed: 1982-11-29
Abstract: A local area network, e.g. serving several floors in a building, is formed from sections of transmission line (Li) coupled together via repeaters (R1, Rn), the loop being closed by a common circuit (UCB), which inter alia, provides synchronisation. Each repeater can also give access to the loop to a station or port (see below). The signals are routed in a time frame the first part of which is used in a packet switching mode and the second part of which is used in a circuit switching mode. To increase the telephone traffic capacity, telephone ports (P1, P2, P3, P4) are provided at various points of the loop to purge it of the 8-bit bytes used in the second segment of the time frame. A port does this by removing bytes circulating upstream of that port, and inserting bytes for circulators towards a downstream port or station into the loop. A time switch (CT) interconnects the loop sector and the outside world, public exchange or PBX, under control of a common control circuit (UCT). <IMAGE>

Title: Adjusting nip roller pressure for feeding photosensitive web material
Inventor: MIYASAKA EIJI
IPC: G03B27/14
Filed: 1983-04-14
Abstract: The nip pressure of rollers feeding photosensitive web material in a duplicating camera is changed or relieved, eg by adjustment of cam (9) bearing on a spring loaded roller support(s). The cam may be adjusted in stages when thicker web material is passed through the rollers or in response to ambient temperature or humidity changes. The cam may be adjusted automatically by a temperature sensor (20) initiating a signal when a preset temperature change is exceeded, Fig. 6. The arrangement obviates distortion in the web which tends to swell upon humidity and temperature changes. <IMAGE>

Filed: 1985-07-03
Abstract: A magnetometer includes a twin fibre (2,3) interferometer, the fibres being coated with a layer of magnetostrictive material 5,6, to cause the optical length of the fibres to change under the influence of a field. Modulated light from a laser source (1) is split at 4 and after passage through the fibres is recombined at 11 to produce an interference fringe pattern which is detected at 12. Solenoid and Helmholtz coil assemblies 9,10 apply magnetic fields 7,8 with a.c. and d.c. components to the fibre, in addition to the external fields 21,22. Signals from two synchronous detectors 19,20 control feedback circuits 25,26 which supply the d.c. current to the field coils 9,10 in order to balance the external field. The voltages required to achieve this are applied to sum and difference amplifiers 28,27 to produce outputs representing the mean total field and the field gradient, respectively. <IMAGE>
