Title: Holographic memory system
IPC: G11C13/04
Filed: 1971-04-20
Abstract: 1343924 Magnetic holograms RCA CORPORATION 20 April 1971 [23 April 1970] 10050/71 Heading H3B [Also in Division G2] In the formation of a holographic memory system on a storage medium 26 a first hologram 29 is illuminated and gives rise to the object beam 29 and reference beam 19, the latter as an undiffracted beam emanating from hologram 29. The information may be a page array 30 of memory units. The hologram 29 then consists of a matrix of holograms 27, one corresponding to each unit of page 30, so that by altering the path of illuminating beams 14, 14<SP>1</SP>, 14<SP>11</SP> by X-Y deflector 12 appropriate object and reference beams are formed to illuminate the desired unit of information and record it at a desired location on hologram 26. Reference beam 19 emanates normally from a hologram 27 and is created by a normally incident illuminating beam 14. Desirably an original laser beam passes a KDP crystal 11 before the X-Y deflectors 12. The page array 30 may be an integrated array of electrically and optically accessible memory units. It is preferred that hologram 27 be an erasable medium, e.g. of manganese bismuth on mica, sapphire or glass. In the write phase the beam is given one state of polarization by rotator 11. Another polarizer 18 located before page array 30 permits the object beam to illuminate the appropriate memory unit. In the read phase polarizer 11 is switched to a state 90 degrees different from write phase, polarizer 18 blocks the object beam and so only the reference beam impinges on hologram 26. If hologram 26 is a reflection hologram the information reconstructed may reflect back to the appropriate sensors of page array 30. To properly transpose the reference beam, where the page array 30 is reflective and not transmissive, a mirror and corner cube assembly 20, 22 may be used. Alternatively a mirror 20, cylindrical lens 40 (Fig. 3, not shown), mirror (42) and cylindrical lens (44) may be used. An alternative embodiment is shown in Fig. 5 where the page array (30<SP>1</SP>) is transmissive.

Filed: 1972-03-06
Abstract: 1382144 Centrifuge R STEIMEL 6 March 1972 [11 March 1971] 10269/72 Heading B1D [Also in Division F4]  The floor 1 of centrifuge drum may be raised vertically from a discharge position (as shown at the right-hand side of the Figure) to engage with and lift the shell 2 of the drum off a support ring 31 (as shown at the left-hand side of the Figure) so that the drum can be rotated by a hydraulic motor 4 attached by its shaft 3 to the floor 1, the motor 4 being secured to a support plate 43 axially guided in a housing 5 to which is secured a cylinder 7 resiliently supported by a rubber bush 11 for lateral movement. The floor 1 is raised by supplying pressure medium at 46 to the journal 7 to force upwards a piston 44 secured to the plate 43. Centrifugal liquid passes through a perforated screen 19 and openings between flanges 15 and 17 into a trough 21 from which it is discharged by a pipe 22. After centrifuging, the batch of material or articles are discharged (by lowering of the floor 1) into a hopper 33 having a floor 35 sloping towards a discharge opening 34, the hopper 33 being secured to the housing 5 and having baffles 36, 37. The next batch is loaded into a supply hopper 38 while the previous batch is being centrifuged; when the floor is raised again after discharging, the closure 40 is raised by supplying pressure fluid to a cylinder 41 to deliver the batch uniformly to the slowly rotating drum.

Title: Improvements in or relating to the Conversion of Delta<5(10)>-Steroids to 10beta-Methyl-Delta<4>-Steroids
IPC: C07J5/00
Filed: 1967-03-03
Abstract: 1,179,621. 3 - Keto - 11# - hydroxy - #<SP>4</SP> - Steroids. SYNTEX CORP. 3 March, 1967 [14 March, 1966; 20 Feb., 1967], No. 10298/67. Heading C2U. 3 - Keto - 10# methyl - 11# - hydroxy - #<SP>4</SP> - steroids which contain a 13-alkyl group are prepared by treating 3-keto-11#-hydroxy-#<SP>5(10</SP>- 19-nor-steroids which contain a 13-alkyl group with an iodomethyl metal iodide in a non- aqueous solvent medium. The starting materials may in turn be prepared by oxidizing a 3-lower alkoxy - 11α-hydroxy-13-alkyl- #<SP>1,3,5(10)</SP> - steroid with an N,N<SP>1</SP>-di(hydrocarbon substituted)- carbodiimide in a hydrocarbon sulphoxide solvent and in presence of dichloroacetic acid to the corresponding 11-keto steroid and converting this to the required product by 11-keto reduction, Birch reduction and mild acid treatment. The starting materials in this process may in turn be prepared from the corresponding 11-unsubstituted-#<SP>9(11)</SP> -steroids by hydroboration and treatment with H 2 O 2  in presence of a base. In the oxidation of an 11α-ol to an 11-one other OH groups may be oxidized, e.g. 3-methoxy-estra-1,3,5(10)-triene-11α,17#-diol is converted to the 11,17-dione and the corresponding 19-notpregnatriene- 11α,20#-diol is converted to the 11,20-dione; and in the subsequent reduction, e.g. with lithium tri-t.-butoxy-aluminium hydride, any keto groups are simultaneously reduced. In the hydroboration reaction a 17- ethylidene starting material is converted to the corresponding 11α,20#-diol; and a 17-keto group is reduced to a 17#-OH group. The iodomethyl metal iodide is prepared in situ from methylene iodide and a metal couple. In the final products any OH groups present other than the 11#-OH group can be oxidized by mild oxidation, e.g. with aluminium isopropoxide. A 17#-OH group can be esterified at an appropriate stage in the process, e.g. before reaction with the iodomethyl metal iodide. 3 - Methoxy - 19 - norpregna - 1,3,5(10),9(11),- 17(20)-pentaene is prepared from 3-methoxyestra - 1,3,5(10),9(11)-tetraen-17-one and ethyl triphenylphosphonium bromide in dimethyl sulphoxide with sodium hydride. 18-Alkyl homologues are prepared similarly.

Title: Improvements relating to turbine-driven compressors
Inventor: CZERNIN ALEXANDER
Filed: 1953-04-15
Abstract: 761,057. Centrifugal and axial-flow compressors; gas turbine plant. FAIREY AVIATION CO., Ltd. July 14, 1954 [April 15, 1953], No. 10346/53. Classes 110 (1) and 110 (3). In a plant of the type comprising an output compressor for supplying compressed air to an external consumer and driven by a turbine, and a combustion-air compressor driven by the same or a separate turbine and supplying combustion air for the turbine or turbines, a pressure-release valve in the delivery passage of the output compressor is subjected to a closing force which is a function of the pressure at a point in a compressor driven by the turbine or turbines. In the embodiment shown, the output compressor 13 is driven by a turbine rotor 22, while the combustion-air compressor 15 is driven by a turbine rotor 23, the rotors 22, 23 forming successive stages of a single turbine driven by gas from combustion chambers 16. To prevent surging in the compressor 13 under low load conditions, a blow-off valve 17 in its delivery passage 14 is acted on by a bellows 18 to which compressed air is admitted through a pipe 21 from a point 19 of the compressor 15. Point 19 may be at an intermediate stage, as shown, or at the delivery of compressor 15 and part of the closing force on valve 17 may be provided by a spring. Valve flutter may be prevented by a damper. The speed of compressor 13 may be maintained constant by a speed governor (not shown). Compressed air is delivered through delivery passage 14 to a pipe grid (not shown) which may also be fed by a second plant. The pipe grid supplies different consumers, such as jet propulsion units and turbines. In a modification, compressors 13, 15 are mounted on a common driving-shaft together with a two-stage turbine which drives both compressors. The compressors may be of the centrifugal type instead of the axial-flow type shown.

Title: Improvements relating to mechanisms for releasing loads
Inventor: EBEL FRANCIS LEONARD
IPC: B64D1/04
Filed: 1953-04-15
Abstract: 744,843. Dropping articles from aircraft. FAIREY AVIATION CO., Ltd. July 14. 1954 [April 15, 1953], No. 10371/53. Class 9(2) A release mechanism which includes a release member and comprising electromagnetic means with a main armature latching the release means and an auxiliary armature locking the main armature until released by excitation of the electromagnetic means is provided with a manual release device which can cause the same movement of the main and auxiliary armatures as the electromagnetic means. The release mechanism comprises a solenoid-controlled latch mechanism for holding a spring-loaded plunger 11 in the cocked position of Fig 1, the plunger being used to operate in a known manner a bomb hook mechanism. The plunger 11 carries a transverse pin 16 engaged in a pair of forks 17 extending from a lever 18, which is pivoted in the metal housing for the mechanism. At the other end of the lever is an arm 21 having an arcuate surface 22 concentric with the pivot 19. The lever 18 has a shoulder 23 engaged by the hooked end 25 of a spring-pressed bell crank 24 when in the cocked position. The bell crank 24 has a vertical arm 28 which is attracted by a solenoid 29, when the latter is energized, and so the bell crank is rotated anti-clockwise to release the lever 18, whereupon the spring 14 moves the plunger longitudinally. Accidental release of the plunger is prevented by a safety lever 31 engaged by a pin 34 projecting from the bell crank 24. An arm 36 of the lever 31 forms a second armature for the solenoid. When the solenoid is energized the lever 31 rotates clockwise, releasing the pin 34, against the action of a spring 35 and thus frees the bell crank 24. So that the solenoid circuit can only be completed when the mechanism is fully cocked, the circuit is closed when a boss 38 on the lever 18 engages spring contacts 39, 40. The manual release mechanism comprises two bell cranks 42, 43 pivoted on the casing and each having an arm parallel to the axis of the solenoid and connected by a floating lever 44 secured to a plunger 45. When the plunger 45 is withdrawn, the lever 44, which is urged by a spring 46 towards the solenoid, causes the free arms of the cranks 42, 43 to move into contact with the armatures 28, 36 and move first the safety catch then the trigger bell crank into contact with the solenoid 29 to trip the release mechanism. To test whether the mechanism is fully cocked a spring-stressed plunger 50 slidable in a collar 51 is pushed inwards to bear against one end of the lever 44. This movement rocks the lever about a stop 53 causing the crank 42 to rotate into contact with the trigger 24 and release the hook 25. If the mechanism is fully cocked, the safety catch 31 prevents movement of the trigger 24. The safety catch 31 and trigger 24 act in opposition so that an acceleration along the axis of the solenoid cannot operate the mechanism.
