Patent GB-2126722-A (GB)
Title: Inertial wellbore surveying system
Inventor: ANDREAS RONALD DEAN
IPC: E21B47/022
Filed: 1983-09-05
Abstract: The tool is lowered down into a borehole on an electrical cable. A computer positioned on the surface communicates with the tool via the cable. The tool contains a sensor block which is supported on a single gimbal, the rotation axis of which is aligned with the cylinder axis of the tool and, correspondingly, the borehole. The gyroscope measurement of the sensor block rotation is used in a null-seeking servo loop which essentially prevents rotation of the sensor block about the gimbal axis. Angular rates of the sensor block about axes which are perpendicular to the gimbal axis are measured by gyroscopes in a manner similar to a strapped-down arrangement. Three accelerometers provide acceleration information as the tool is lowered within the borehole. The uphole computer derives position information relative to the well head based upon acceleration information and angular rate information. Kalman estimation techniques are used to compensate for system errors.

Title: Process for improving activity of tellurium-containing metal oxide catalysts
Inventor: SASAKI YUTAKA
IPC: C07C255/08
Filed: 1984-08-08
Abstract: A process for improving the activity of tellurium-containing metal oxide catalysts useful as catalysts for oxidation, ammoxidation or oxidative dehydrogenation of organic compounds by heating the catalysts together with a molybdenum- and tellurium-containing solid to a temperature up to about 900 DEG C in a gaseous atmosphere. The process can be effectively applied not only to deteriorated or spent catalysts, the activity of which has been deteriorated due to use for a long period of time, but also to fresh catalysts. In a particularly preferred embodiment, the process for improving the activity according to the present invention can be carried out by contacting said tellurium containing metal oxide catalysts with the molybdenum- and tellurium-containing solid in a fluidized-bed. More preferably, the contact is carried out during the oxidation, ammoxidation or oxidative dehydrogenation reaction.

Title: Friction clutch with auxiliary flywheel
Inventor: DOLL PETER
IPC: F16D21/08
Filed: 1985-01-23
Abstract: A drive system such as for motor vehicles comprises an internal combustion engine E, a gear box 28 and a starting and gear change clutch 1 between the internal combustion engine and the gear box. In view of avoiding "gear rattle" a flywheel 20 is provided for being coupled with the input shaft 26 of the gear box in normal operation and for being decoupled from the gear input shaft in response to disengagement of the starting and gear change clutch. A clutch release bearing assembly 29 may cause both release of the clutch 1 and decoupling of the flywheel 20 by moving a friction ring 23 out of contact therewith. Alternatively, there may be two release bearing assemblies actuated simultaneously by a common cam to disengage the clutch 1 and flywheel 20 respectively. In other forms, the flywheel 20 is disposed within the clutch 1 and is coupled by frictional connection to the driven disc 6 of the clutch 1. <IMAGE>

Patent GB-2157866-A (GB)
Title: Shutter arrangements
Inventor: JERVIS EDWARD RICHARD
IPC: G06K13/08
Filed: 1985-04-12
Abstract: A shutter arrangement for the card transport of a device for processing data bearing cards, for example a parking meter for processing magnetic cards, includes a shutter member pivotable about an axis (A, A) which is parallel to the plane of the card transport path (13), having a closure portion (41) which is normally spring biased (50) to extend into the transport path (13) and which has a ramped rear surface (42), and having an actuating portion (43) which is in the path of the solenoid plunger (31). On insertion of an authorised card the solenoid (30) is energised and the plunger (31) pivots the closure portion (41) out of the transport path (13). On insertion of an unauthorised card the solenoid (30) is not energised and the front of the card jams against the closure portion (41) and tends to pivot it further into the transport path (13). When a card is driven against the closure portion (41) from within the device the rear of the card rides on the rear ramped surface (42) so as to move the closure portion (41) out of the transport path (13) without the need for energisation of the solenoid (30).

Title: Electrical interconnection arrangement
Inventor: MOBBERLEY MARTIN PAUL
IPC: H01L21/60
Filed: 1985-06-28
Abstract: An electrical interconnection arrangement enables a temporary connection to be made to a very small semiconductor chip for testing purposes without damaging its delicate terminal pads. A thin flexible transparent substrate 3 of electrically insulating material which carries a pattern of conductors is used to link the semiconductor chip 1 to a relatively robust printed circuit board 9. The ends of the conductors which contact the pads 2 of the chips are provided with bumps 14 which project into the recesses within which the terminal pads are often located.

Title: Carbonated beverage container
Inventor: FORAGE ALAN JAMES
IPC: B65B3/04
Filed: 1985-11-29
Abstract: A beverage package and a method of packaging a beverage having gas (preferably at least one of carbon dioxide and inert (nitrogen) gases) in solution has a non-­resealable container l within which is located a hollow pod 4 having a restricted aperture 7 in a side wall. The container is charged with the beverage 8 and sealed. Beverage from the main chamber of the container enters the pod 4 (shown at 8a) by way of the aperture 7 to provide headspaces la in the container and 4a in the pod 4. Gas within the headspaces la and 4a is at greater than atmospheric pressure. Preferably the beverage is drawn into the hollow pod by subjecting the package to a heating and cooling cycle. Upon opening the container l by draw ring/region l3, the headspace la is vented to atmosphere and the pressure differential resulting from the pressure in the pod headspace 4a causes gas/beverage to be ejected from the pod (by way of the aperture 7) into the beverage 8. Said ejection causes gas to be evolved from solution in the beverage in the main container chamber to form a head of froth on the beverage. The pod 4 is preferably formed by blow moulding and located as a press fit within the container l which latter is preferably a can, carton or bottle.

Title: Method and apparatus for uniformly loading particulate material into cylindrical beds
Inventor: SOUERS STEVEN A
IPC: B65G69/04
Filed: 1985-12-04
Abstract: An apparatus for uniformly distributing catalyst particles across the full diameter of a catalyst bed causes a multiplicity of annular rings of catalyst concentric with the bed center to be achieved without varying rotor speed by deflecting catalyst from a feed tube (40) into a plurality of arcuate sectors (24) or portions of different radial lengths on a rotating disc (20). Depending upon the overall cross-sectional area of the vessel, the cylindrical volume of catalyst flowing from the feed tube may be divided into an outer annular column and an inner cylindrical column. In a preferred embodiment this may be done by a frusto-conical member extending upwardly and inwardly into the feed tube from the main distribution surface of the disc. Another plurality of separate arcuate flow paths (52-58) of different radial lengths are rotated by the single rotor or disc. Desirably, each other path is shorter than the radius of any of the arcuate portions formed by the disc. <IMAGE>

Title: Shutting down a rotor spinning machine
Inventor: WOOD ALFRED
IPC: D01H4/46
Filed: 1987-11-26
Abstract: The spinning units of a multi-position rotor spinning machine are driven by a common AD drive motor 9 powered by a static inverter enabling the power supply frequency to the AD motor to be controlled for controlling the operating speed and the rate of deceleration of the AD drive motor. A method of shutting down the machine comprises reducing the input frequency to bring the spinning units to a predetermined, reduced speed, forming a yarn reserve loop in the yarn delivery path stopping sliver feed to the rotors, measuring the rotation of the yarn delivery rollers after stopping the sliver feed to determine the length of yarn delivered and braking the delivery rollers to a stop when a predetermined yarn length has been delivered following the sliver feed stopping. The method provides a precise length of yarn available for feeding back into the rotor when starting up. <IMAGE>
