IPC: G01C25/00
Abstract: 1, 053, 077. Testing, gyroscopes, determining centre of gravity. SOCIETE ALSACIENNE DE CONSTRUCTIONS ATOMIQUES DE TELECOMMUNICATIONS ET D'ELECTRONIQUE "ALCATEL". April 17, 1964, No. 16007/64. Headings G1C and G1X. A gyroscope testing machine comprises a support 12, a container 1 adapted to accommodate the equipment to be tested 3, the container 1 being mounted in a spherical fluid bearing formed in the support 12 and being provided with a cone shaped driving member 13 having a pin 14 engaging an eccentric bearing in a flywheel 30, Fig. 6, the eccentricity being variable. The container 1 is formed as two half-spheres 1a, 1b, and the fluid bearing is formed between the support 12 and half-sphere la by supply of fluid under pressure to cavities as 15. The equipment to be tested 3 is carried in a cradle 4 comprising two rings 4a, 4b and cross-bars 5, and the equipment may be held in any desired position in the container 1 by tightening screws 2, causing the rings 4a, 4b to be clamped inside the half-spheres. The halfsphere 1b is provided with apertures to allow visual observation of the equipment 3. The crossbars are provided with bores to receive trunnions with ball bearings to allow the centre of gravity of the cradle 4 and equipment 3 to be centred at 0, either by addition of weights or by adjusting the position of the equipment 3. The pin 14 on the cone-shaped driving member is held in a bearing 34 comprising a sphere in a needle bearing. The bearing 34 is supported by oil under pressure from a spring, and is arranged so that if the reaction between the pin 14 and sphere exceeds a certain value, a microswitch will be actuated to cut off the drive to the flywheel 30. The sphere 44 is mounted in a wheel 33 for rotation about an axis 0' in the flywheel 30, Fig. 6, which itself is rotated about an axis 0. The wheel 33 is provided with peripheral gear teeth and is rotatable by use of an arm 35. Apparatus for rotation of the worm 35 is described and incorporates a dial comparator to give an indication of the eccentricity of the drive to the pin 14 for the adjusted position of the wheel 33. The eccentric drive to the pin 14 causes movement of the half-sphere 1a in its bearing, the point 0 in Fig. 1 remaining stationary. Resilient stays, Fig. 3 (not shown), are provided between the container 1 and support 12 to prevent rotation of the container about the axis X X'.

In making a film a high polymer melt is extruded at a temperature of 200 to 300 C. through a slot die on to the surface of a rotating, cooled roller, which has a surface temperature of 10 to 80 C., and rotates with a peripheral speed of 5 to 50 meters/minute the viscosity of the emerging melt being more than 2000 poise, and the film is applied flat in a thickness of more than 0À3 mm. on the roller surface and substantially vertically below the die slot, in an electrical high-voltage direct current corona field produced by a voltage of 5 to 30 kV and with the simultaneous application of dynamic gas pressure of 50 to 400 mm. water column upon that surface of the film remote from the roller surface, and further electrical direct-current corona fields, extending substantially along and over the edges of the film are then employed to hold the edges of the film in contact with the surface of the roller up to a subsequent immersion of the film in a cooling bath. The melt is preferably extruded at a specific delivery rate of more than 5000 cm.<SP>3</SP>/hour per cm. of length of slot. The high polymer may be a polyolefin, e.g. polyethylene or polypropylene. In Fig. 1, the melt passes from an etxruder through a feed pipe as shown by arrow A into extrusion die 1. The distance of the edges of the die slot from the surface of the cooling roller 2 is 1 to 10 cm. and the melt has a path of 10 to 300 mm. between the die slot and the roller surface. Roller 2 rotates in a bath 3 containing cooling liquid 3a, e.g. water. An electrode 5 passes through the pressure air housing 4 above the film and over the entire film width. Electrodes 6 and 7 begin inside the housing, extends above the surface of the film and along its edges, and terminate above the level of the liquid in the bath. Two felt strips 9 seal the lower side edges of housing 4 with respect to the surface of the roller. One of two similarly arranged nozzles for regulating the inlet of air is shown at 11. A stream of gas preferably air produces on the surface of the film the required pressure.

A pair of two-section fluid or electric telescopic jacks 12 with a third section 13 comprising a shock absorber or damper are each pivotally attached at the one end to the fuselage at 26 and at the other to one of a pair of supports 16 for the ground contacting member 25. One end of each support member 16 is also pivotally attached to an arm 14 which is pivotally attached at 15 to the fuselage. A guiding member 18 is pivotally attached to each arm 14 and to quadrant gears 21 pivoted at 23 the gears intermeshing to prevent fore-and-aft movement of the ground-contacting member 25. To retract, the jacks 12 are telescoped, causing the ground contacting member 25 to move up along the path indicated by broken lines and lock in position by means (not shown) associated with the quadrant gears or the mechanical jacks or both. In an alternative embodiment the jacks 12 may be substituted by at least one jack operating directly between the aircraft structure and one of the gears 21.

Radio-active waste in a hot cell B is removed by lifting a plug 36 closing an orifice in the lower wall 32 of the hot cell and transferring the waste through the orifice into an ash can 14 disposed in a flask 10 transportable on a carriage 28. The ash can 14 is thin-walled and made of resiliently deformable material, e.g. polyethylene, and is formed at its upper end with a groove 50 for receiving a cover 16. During filling of the ash can the cover 16 is attached to the plug 36 by jamming engagement of a disc 66 within a cylindrical extension 56 of the cover. The disc 66 is carried by a push rod 60 which may be retained in the retracted position, Fig. 1, by resilient members 70 engaging a groove 74. After the ash can 14 is filled the plug 36 is replaced and the push rod 60 is depressed so that the cover 16 snaps into the groove 50, Fig. 2. A table 30 carrying the carriage 28 is then lowered to disengage the flask 10 from a centering extension 40 and the flask is positioned beneath its cover 12. On raising the table 30, latches 44 retaining the cover 12 are released. The flask 10 closed by its cover 12 is brought to a waste disposal site where sliding doors 20, 22 at the base of the flask are opened so that the ash can 14 may drop out. In a modification (Fig. 3, not shown) the cover 16 is temporarily attached to the cover 12 instead of the cover 36 and the cover 12 carries the push rod.

Abstract: 1,251,382. Semi-conductor devices. PLESSEY CO. Ltd. 21 Feb., 1969 [6 March, 1968], No. 10833/68. Heading H1K. An opto-electronic device comprises at least one photo-emitter E and a plurality of photo collectors C on the same surface of a translucent insulating substrate 3 provided with reflecting means 5 to facilitate light transmission between the emitter and the collector. The embodiment shown includes a single emitter E surrounded by eight collectors C coupled in pairs to Darlington type amplifiers, the arrangement being used as a relay. A similar arrangement may serve as an amplifier. The structure is formed by epitaxially depositing an n-type GaAs layer 2 on a p-type GaAs layer 1, and then epitaxially depositing an insulating GaP support 3 on the layer 2. Regions 4 of the layers 1, 2 are removed, leaving the photo-emitter and collectors E, C, to which ohmic contacts are applied. A reflective coating 5 is provided, and the structure is encapsulated. In an alternative form depressions are etched in the surface of a semi-insulating GaP substrate (6), Fig. 2 (not shown), and n-type GaAs (7) is deposited therein, excess material being polished off. Depressions are etched in each of the n-type portions (7), the depressions being deeper in the portions which are to provide the photo collectors. Lower conductivity n-type GaAs (8, 9) is epitaxially deposited in these depressions, excess material again being polished off, and Zn is diffused into the GaAs pockets to convert only the lower conductivity n-type regions (8, 9) to ptype conductivity. A reflector layer (10), ohmic contacts and encapsulation complete the device. In a modification a p-type Ga/InAs alloy may be deposited to form the regions (9), thereby defining p-n photo collector heterojunctions. The emitter junction is made as previously described.
