Patent GB-934222-A (GB)
Title: Improvements relating to grab devices
Inventor: POUNDER JOHN ORMEROD
IPC: G21C19/105
Filed: 1961-01-05
Abstract: 934,222. Servicing reactors. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Dec. 29, 1961 [Jan. 5, 1961], No. 504/61. Class 39 (4). A grab for servicing a reactor in the manner disclosed in Specification 934,221, in which a fuel element is extracted from the reactor core by a grab and placed in a liquid-filled carrier adjacent the core, the carrier then being removed from the reactor by the grab, comprises a tubular housing 11 having longitudinal slots 13 accommodating two sets 14a, 14b and 15a, 15b of claw plates. The plates have outwardly-directed hooks at their lower ends so that when these hooks are moved outwardly by rotation of the plates about pivots 16, 17 the hooks may engage beneath internal recesses formed in the open tubular end of the part to be lifted. The claw plates 14a, 14b serve for lifting a fuel element and have hooks which are moved outwardly to a lesser extent than the hooks of plates 15a, 15b which serve for lifting the carrier. The claw plates are operated by a longitudinal actuating member 20 having, for each plate, three cam tracks 21, 22, 23 cooperating with projections 18, 19 on the plates. The arrangement is such that the claw plates are at all times positively held by engagement between the projections and cam tracks. To lift a fuel element the grab is lowered until contact is made with a stop 24 on the housing 11 whereupon the actuating member 20 is raised so that projections 19 of the plates 14a, 14b leave the cam tracks 23 and move on to the tracks 22 and projections 18 move from the tracks 21 to the tracks 23, thereby pivoting the hooks outwardly to engage the fuel element. The grab then lowers the fuel element into the carrier until the carrier is engaged by a stop 25 whereupon the member 20 is raised through a further extent so that the projections 19 on the plates 15a, 15b engage the cam tracks 22 and projections 18 engage the tracks 23 and thus the hooks on the plates are moved outwardly to engage the carrier. Hence when the grab is subsequently raised both the fuel element and the carrier are independently lifted by their respective hooks.

Title: Improvements in and relating to electric switches
IPC: H01H9/00
Filed: 1923-01-06
Abstract: 213,958. Tucker, A. W. G., and Ferranti, Ltd. Jan. 6, 1923. Retractive switches for tapping transformer windings and located in the transformer oil tank comprise a single or double contact arm c adapted by the operating-handle g, first to be withdrawn from fixed contacts b in the casing a, against the action of a spring k surrounding the fixed stub spindle e on which the contact arm is longitudinally and rotatably mounted, and then to be rotated until opposite other contacts. On release, the contact arm engages the other contacts and is guided thereto by a fixed notched cup m with which a portion of the contact arm engages. The switch casing is located near the centre of the transformer so as to facilitate wiring and is operated from the exterior by the handle g connected with the switch-driving sleeve f (to which the contact arm is operatively secured) by coupled sections of shafting with universal joints j. In an adaptation to three phase transformers, Fig. 6, a switch similar to that already described is provided for each phase and all three switches are operated by a common handle through a single shaft. The casing of each switch is supported on trunnions x, y so that during erection correct alignment between the switch-driving sleeves and their bushings is facilitated. A separate hand lever t is provided to take the contacts out of engagement.
Patent GB-688199-A (GB)
Title: Process and apparatus for recovering oil from swarf
IPC: C10M175/04
Filed: 1949-01-07
Abstract: <PICT:0688199/III/1> <PICT:0688199/III/2> Oil is recovered from swarf by conveying the swarf through a volatile solvent having a boiling point lower than the flash point of the oil, and subjecting the oil-bearing solvent to fractional distillation.  The swarf may be passed only through the vapour of the solvent, the temperature of the swarf in this case being lower than that of the vapour so that the latter condenses on the swarf. Alternatively the swarf may be passed through the boiling solvent and then through a zone in which any solvent remaining on the swarf evaporates, the evaporated solvent condensing on the walls of the zone.  The oil-bearing solvent may be filtered before the fractional distillation, and the oil, after separation from the solvent, may be dehydrated, e.g. by centrifuging. Suitable apparatus comprises a trough-like container 10 for solvent having a well 11, heating tubes 12 and an inlet 14 for swarf, which is delivered on to a continuous belt or like conveyer 24 passing over sprockets 28, 30.  The conveyer carries the swarf upwardly through the vapour zone 32 of the apparatus, in which solvent which vaporizes from the swarf is condensed by means of condenser tubes 33.  The cleaned swarf is discharged through an opening 36 to a crushing plant 38, from which it is carried by a conveyer 39 to a discharge vehicle 40.  The oil-bearing solvent is drawn from the container 10 by a pipe 41, (Fig. 2) and passed through a filter 42 to a still 43.  Solvent from the still is condensed in a condenser 57 and passed to tank 48, which feeds the container 10. The oil from the still is passed to a centrifuge 52, wherein any water present is separated.  When it is desired to treat the swarf solely with the vapour of the solvent, the latter is confined to the well portion 11 of the container. Specification 540,254 is referred to in the Provisional Specification.

Title: A pressure testing system for oxygen demand regulators
Inventor: FITT PETER WILLIAM
IPC: A62B27/00
Filed: 1961-01-10
Abstract: 957,441. Respiratory appliances. NORMALAIR Ltd. March 20, 1962 [Jan. 10, 1961], No. 960/61. Heading AST. A control unit for testing the demand regulator of an aircraft supply system is remotely placed from the regulator and controls the latter by a relay valve through which it applies a predetermined pressure to the diaphragm. The relay valve is located adjacent to the regulator to prevent pressure pulsations in the communicating connection. In the relay valve a large bore connection 14, leading from the regulator diaphragm chamber, terminates in a valve seat 18 which is normally open to atmosphere but may be closed by a diaphragm valve 22 when pressure is applied to the inner face of the latter through a connection 11. Under these conditions the pressure in the connection 11 is communicated to the regulator diaphragm through a bleed hole 23, while the valve is held closed by the pressure on the excess area of its diaphragm. In the control unit, oxygen under pressure enters through an inlet 31 but is normally prevented from passing further by a closed valve 32. Depression of a control knob 37, however, opens this valve by means of a pushrod 35 and, at the same time, closes the upper end of the tubular member surrounding the rod 35 by means of a valve 36. Oxygen under pressure consequently passes out through duct 33 to the connector 11 on the servo-valve to actuate it and the maximum pressure reached is determined by a relief valve 39 which, when open, allows excess oxygen to pass out through an outlet 38. Depression of an additional knob 41 serves, however, to close this path and the gas must additionally pass through a second relief valve 42, to reach an outlet 43. The release pressure of this second valve 42 is set higher than that of the valve 39 and thus the unit may be used to apply either of two predetermined pressures to the regulator, such as for testing mask and suit supplies. When the knobs are released the inlet valve 32 again closes and the pressure in the connection to the relay valve is exhausted through the duet 33, open valve 36 and outlet 38. Specifications 944,931, 944,932 and 944,933 are referred to.

Abstract: 295,544. Knorr-Bremse Akt.-Ges. Aug. 18, 1927, [Convention date]. Direct air-pressure apparatus, non-automatic.-Vehicular apparatus for spraying tar &c. on roads by means of air under pressure supplied by a compressor 2 driven by the propelling engine 1 has the compressor mounted on a tractor and the compressed air tank 5 and tar tank 6 carried on a trailer 3. When the suction of the compressor is utilized for filling the tar tank, a float valve 12, Fig. 2, is provided on the tar tank to shut off the tank from the suction pipe when the tank is full. The compressor draws air from the atmosphere through a perforated cap 9 and delivers through a pipe 4 to the compressed air tank 5. The air under pressure in the tank 5 passes by the float valve 12 and acts on the tar in the tank to spray tar through a pipe 19. When the valves 8, 21 are closed and the valve 11 is open, suction through a pipe 10 acts to exhaust air from the tank 6 to permit tar to rise through a filling pipe 18, the float 17 rising to close the suction pipe 10 when the desired level is reached. A safety enlargement 20 in the pipe 10 also prevents tar from reaching the compressor. The pipes 4, 10 are fitted with detachable hose unions and the compressor 2 is readily detachable to permit the tractor to be used for other purposes.

Title: Block pattern detection circuit
Inventor: CULP BRADFRED
IPC: G11B20/18
Filed: 1994-04-14
Abstract: Block pattern detection circuitry for the read subsystem of a streaming tape drive system comprises a state machine (20), a pattern decoder (30), a tape mark detector (40), a block/gap filter (50), a block/gap meter (60), a verify count section (10), and a block read/verify section (80). The incorporation of a hardware state machine (20) within the block detect circuitry permits the application of historical detect data in the interpretation of present detect data. This provides more certain pattern recognitions. Also, state data is fed back to the block/gap filter (50) allowing precise block boundary triggers which are used by position capture circuitry and the drive controller to effect more precise re-try positioning. The use of the block/gap filter (50) increases the detect circuitry's immunity to noise. The advantage is enhanced where the block/gap filter (50) uses stochastic thresholding, which is also advantageously employed by the tape mark detector (40).
