Patent GB-2116901-A (GB)
Title: Extruding a dielectric sheath around a joint in an optical fibre cable
Inventor: JONES MARTIN PHILIP
IPC: H01B13/14
Filed: 1982-03-04
Abstract: An optical fibre cable having a strength member has a dielectric sheath estruded over it. When a joint is to be made in the optical fibres or in the strength member which would necessarily result in a bulge in the cable at the point of the joint, this joint is nevertheless drawn through the extruder which has a variable extruder point to accommodate the bulge, whereby a jointed cable can pass through a continuous extrusion process without the need for stopping the extrusion process. Any reinstatement or making good of the dielectric sheath is done after the sheath has been extruded, at the point of the joint.

Title: Screening tape
Inventor: SACH JOHN ROBERT
IPC: H01B11/08
Filed: 1982-06-10
Abstract: A screening tape for use between "go" and "return" conductor compartments of a telecommunications cable for pulse code modulated transmissions, comprises an aluminium foil tape 30 coated on both sides up to its edges with polyethylene 31 with minor longitudinal edge portions folded over so that the edges 34 of the resultant screening tape are not sharp and pose no threat of damage to conductors of the cable. The voids 35 may be sealed with adhesive to prevent ingress of water. Apparatus for forming the tape comprises bending rollers (42, 43 Figs. 4A, 4B not shown), an intermediate die (44) and flattening rollers (45, 46). Alternatively a set of dies is used for forming the tape (Figs. 5A to 5B not shown). <IMAGE>

Title: AC plasma panel control
Inventor: MARENTIC MICHAEL J
IPC: G09G3/292
Filed: 1982-06-14
Abstract: In an AC plasma matrix panel, border sustain circuits needed for generating a constant supply of free particles are eliminated by the application of a 'distributed conditioning' waveform to all display cells, e.g. at 120 Hz, causing them to discharge without loss of memory of their ON/OFF state, which at other times is preserved by a sustain waveform. These waveforms, together with WRITE, ERASE and BULK ERASE are provided from ROM's addressed by logic signals. The first pulse 1 of the distributed conditioning waveform reverses wall charge only on a cell already ON, causing a flash; pulse II adds wall charge and fires only a cell already OFF, causing a flash at f and again at the pulse end at g: pulse III reverses wall charge on a cell originally ON, causing a second flash and leaving the cell ON. The flashes at 120 Hz are negligible against the 50 kHz flashing of ON cells. <IMAGE>

Title: Apparatus for heat sealing and crimping a skirted cap on a container
Inventor: WAITE PHILIP SIDNEY
IPC: B65B7/28
Filed: 1982-09-23
Abstract: In apparatus for heat-sealing a skirted cap on to the lip of a container of glass or other material and to crimp the cap skirt against the exterior of the lip, the heating platen (9) is assembled as a unit with the crimping means (11,12,14), and the unit is detachably secured by a single fixing screw (7) to the block (2) in which the electrical heating element is embedded. Thus, if parts of the apparatus, namely the platen and crimping means which can be contaminated by broken glass or the contents of the container should become so contaminated, they can be readily removed and replaced without removing the heating element or the electrical wiring, thereby reducing production loss. The construction also enables a quick change to be made to alternative heads for sealing different types or sizes of containers. Crimping is effected by radially compressing the skirt of the resilient sealing ring (11) by the radially movable members (12) when the outer ends of the latter engage cam members (18), in the form of vertical leaf springs, upon the unit being pressed against the lip of a container. <IMAGE>

Patent GB-2111653-A (GB)
Title: Fluid friction coupling with a temperature control device
Inventor: MARTIN HANS
IPC: F16J15/3228
Filed: 1982-12-07
Abstract: A fluid friction coupling has a temperature control device which comprises a bimetallic strip control member which acts on a valve lever via a switching pin (7). The pin (7) is guided through a coupling wall (12) and protrudes at one end into a space in which coupling fluid is located. The switching pin seal is an elastic sealing membrane (14), the aperture of which fits in pre-tensioned fashion on the switching pin (7), the periphery (18) of the membrane being fixed in the wall. The dimensions are such that the friction forces between the pin and the membrane are greater than the restoring forces caused by its elastic properties, so that the rim of the membrane does not slide on the pin but moves with it accompanied by deformation of the membrane. This ensures that no friction occurs between the membrane and the switching pin which might have an undesirable effect on the control characteristics. <IMAGE>

Title: Linear shear valve
Inventor: LARRONDE MICHAEL L
IPC: E21B47/18
Filed: 1983-08-19
Abstract: A mud pulse telemetry system for imparting data pulses to drilling fluids circulating in a drill string includes an improved valve arrangement for modulating the pressure of the circulating drilling fluid is disclosed. A shear-type valve 36, 38 is arranged in a through conduit configuration 43, 44 so that the seat face 51 of the valve is covered when the valve is in an open position, thus preventing impingement of abrasive fluid particles on the valve seat face during the open flow position of the valve. The activation means is connected to the valve gate through a floating connection 52 which prevents lateral stress forces operating on the valve from being imparted to the solenoid 56. The floating connection 52 also permits convenient removal of the valve seat 36 and gate 38 from an access opening on the exterior of the drill string housing to facilitate the replacement of critical valve parts without removing the valve subassembly from the drill string. The valve gate 38 and seat 36 each have an oblong valve flow opening therein which provides for sufficient fluid flow to adequately modulate the fluid pressure and at the same time provide a minimum length of stroke for the solenoid to operate the valve. An upset rim 51 on the valve seat 36 provides a seating face smaller than the opposing seating face of the gate. The valve arrangement includes a latch device (not shown) for controlling the valve which includes a latching solenoid armature is connected to the valve gate through separate open and close solenoids having their armatures operatively connected to act as a single unit. The single unit armature is normally restrained from movement by the solenoid deactivated latch device. The latch device is arranged so that the vibrational and impact loads on the drill string serve to further maintain the modulating valve in a closed position. <IMAGE>

Title: Radio controlled switching devices
Inventor: HUDSON HERBERT
IPC: G08C17/02
Filed: 1983-10-19
Abstract: A switching device comprising an aerial 10, a filter 11, an envelope detector 12, an amplifier 13 and a switch 14 connected in series. An aerial is mounted in a building so that it can pick up signals transmitted outside the building. These signals are filtered at 11 to limit the range of frequencies to which the device will respond and after amplification they are compared with a predetermined threshold level. If the amplified signal exceeds the threshold level a signal is passed to switch 14 causing it to switch on the lights in the building. Thus the switch can respond to the operation of the transmission button of a police radio. <IMAGE>

Title: Carrying out value input and output operation to a trip recorder microprocessor using the recorder display.
Inventor: WEBER ROBERT
IPC: G01D18/00
Filed: 1984-05-31
Abstract: In an electronic trip recorder a microprocessor 1, via a stepping motor 7, controls display 14 and recording means 13 according to signals received from various transducers, in normal use. A switching means 4 produces pulse sequences which enable the display to be deflected other than in response to the transducer signals. To feed in calibration information e.g. an actual speed, switch 4 is operated until the corresponding deflection at the display has occurred. Corresponding information is stored under control of the microprocessor and used during calibration to produce a constant enabling current conversion between transducer signal and displayed quantity. Such constant may be displayed by appropriate operation of the switching means so that the display is deflected until it automatically stops at a position corresponding to the constant (repeated deflections may be involved, one for each digit of a multi-digit number, in both input and output operations). The pulse sequence from 4 may be briefly interrupted at well defined display positions (10 kph = 1, 20 kph = 2, etc). <IMAGE>
