Title: Oil pipe line connection - has sleeve and worm to apply compression forces onto seals (NL180576)
Inventor: SHOTBOLT KEITH
IPC: E21B17/04
Filed: 1974-11-14
Abstract: The connection is esp. suitable for pipe lines, which are subjected to high pressure strains or construction forces. It contains a self-clamping section, to prevent the pipe ends from being pulled out of the connection unit. It also has a housing, and seals, to seal the pipes against each other. The compression force of the seals onto the pipe lines to be connected, and onto the connection elements, is applied by a sleeve, and a worm, supported in bearings in the housing. The axial position of the worm is maintained during tensioning, and the sleeve revolves about its axis, in order to move two compression elements in opposite directions against the seals. At least one of the seals guarantees a sealed separation between the outside medium and the tensioning actuator for the seals.

Title: Self adjusting draught excluder for doors - has flexible sealing strip hinged to rigid support section on door
IPC: E06B7/18
Filed: 1974-11-21
Abstract: The self adjusting draught excluder for e.g. a door has a sealing strip hinged to a support strip, permitting it to retract to ease door mobility and return to an active position upon encountering the fixed door frame. The support strip (a) is rigid, with a vertical web terminating in a 'C' section hooked end, and is fixed to the bottom of the door by screws through the web to form, with the door edge, a longitudinally slotted conduit. The sealing strip (c) is semi-flexible and has a bulbous beading on one longitudinal edge which is fixed in the conduit to permit sealing strip rotation of 90 deg. When the door is opened the seal pivots to lie flat against the underside of the door, and pivots back 90 deg. to bear against the fixed door frame upon closure.

Title: Pincers for fastening metal binders - has force transmitted from pressure bar to lever arm by ball between cammed face and spring
IPC: B25B25/00
Filed: 1975-07-08
Abstract: The pincers for fastening metal bindings have a torque limiting mechanism which controls the traction applied to the end of the binder. The tool jaws incorporate a beak and a slot. Hand lever convergence causes the jaws to diverge. The free end of the binder is then drawn by the beak, whilst the other end is immobilised by the slot. Rotation of the tool relative to the beak anchors the binding. The are (12) which applies the traction supports a pivoting (14) pressure bar (13) outside the torque limiter (29). Axial forces are transmitted from the bar (13) to the arm (12) by a ball on a cam surface. When pressure is applied, the ball climbs the ramp, and ball pressure is limited by a spring. Spring (29) pressure may be adjusted by a screw-jack (27, 28).

Title: Single memory unit access system for multiple central processors - has multiprocessor control for time shared address and data transfers
IPC: G06F13/18
Filed: 1975-09-24
Abstract: Operating logic in the data processing system is arranged to provide for an overlapping of the access, or "fetch" operation such that access to a second memory module can be obtained by a processor unit before a data transfer has been completed with respect to a first memory module and read-out of the second memory module can process during the rewrite cycle of the first module to reduce the overall processing time. Such operation may be made more effective by arranging the system to utilize memory interleaving techniques. Further, the system of the invention can provide for multiprocessor operation with a single memory system by the use of appropriate time-sharing techniques wherein processors can be operated in time-phased pairs.

Title: Filter for purifying gases contg. radioactive particles - incorporating flexible impermeable sleeve protecting operator totally during filter changing
Inventor: LAFAIX FRANCOIS
IPC: G21F9/02
Filed: 1976-01-20
Abstract: A filtration appts. for purifying a gas, e.g. air contg. radioactive particles, or noxious gases, incorporates a partition, placed in the path of the gas at right angles to the direction of flow, and in which is a hole surrounded by a projecting rim. A filter, consisting of a rigid frame in which are housed filter elements, is fixed by one of its faces against the downstream face of the partition, over the hole. The filter appts. incorporates a sleeve, open at both ends, made in flexible material impermeable to the gases. One of the ends is fitted on the rim surrounding the hole in the partition. The other end is fitted on the frame of the filter. The dimensions of the frame and the rim on the partition are such as to leave an annular space between them, forming a housing for the sleeve, folded when the filter is in place on the partition. Ensures that the operator is totally protected from of the container from where it is pumped away. The water is de-gassed by continuously evacuating an air space above the level of the mineral/water mixt. at the top of the container. Alternatively the water can be de-gassed before it is pumped to the container. The process is used in the continuous purificn. of granular minerals, esp. quartz sand, and is purely physical, as opposed to the messey chemical processes generally used.

Title: Integral adjusting device for relay contacts - has taper-headed screw pressing against chamfered face to adjust position of moving contact
IPC: H01H50/54
Filed: 1976-07-09
Abstract: A device is used for adjusting the opening and closure of contacts in electromagnetic relays. It enables consistent characteristics to be obtained. It is integral with the relay which has a mobile contact which moves between two sets of double fixed contacts. The device consists of a taper-headed screw (23a, 23b, 23c, 23d).

Title: Roll and yaw stabilisation system for satellites - has horizontal sensor and phase detector which drive magnetic torque generator
IPC: B64G1/32
Filed: 1976-07-19
Abstract: The automatic correction system for stabilising roll and yaw in artificial satellites comprises a roll-error detector in the form of a horizontal sensor sensitive to energy from the earth's surface. A suitable electronic circuit provides a proportional signal in either analogue or digital form. The filtered signal passes to a level detector whose limits are determined by the required positional accuracy of the satellite orbit. If the error exceeds the limit, the direction and magnitude of the error is determined in a phase detector. The resulting control signals pass to a drive unit which determines the polarity of the drive current to an electromagnetic torque generator. The torque generator produces magnetic dipoles which react with the magnetic field of the earth to correct the attitude of the satellite.

Title: High torque continuous current electric motor - uses ferrite magnets and copper braid folded windings with resin insulation minimising required amount of copper
IPC: H02K3/00
Filed: 1976-09-13
Abstract: The direct current motor has a ferrite magnet magnetic circuit which is glued to the interior of the motor frame. The magnetic winding consists of copper conductor encased in resin. The conductor consist of this emanelled copper wires braided together and folded like an accordean. Each fold is maintained by a loop of insulating tape. To reduce the amount of copper and at the same time avoiding the neutralising effect of certain parts of the magnets the magnets are of a diamond shape. Consequently the rotor conductor are wound in a zig zag formation. The flat cables are split between two laminations of the collector. The copper braid layer is placed on a cylindrical mould and joined helically. This layer is surrounded by an insulating tape loop. The cables are then folded over the first layer to form a second layer etc.
