Title: Improvements in or relating to automatic guns or like discharge weapons and to ammunition therefor.
Inventor: LUNATI CHARLES JOSEPH
IPC: F41A9/47
Filed: 1953-06-05
Abstract: 1,243,961. Automatic guns; cartridges. ETAT FRANCAIS. 5 June, 1953 [6 June, 1952; 28 May, 1953], No. 15647/53. Headings F3A and F3C. In an automatic gun, for firing self-propelled missiles, the expulsion gases are discharged so as to reduce recoil, while in an alternative form the gases produce the gun automatic action. In the gun, Figs. 20, 21, part of the expulsion gases thrust the muzzle 29 forward, against the action of the spring 37 and rotate the ammunition feed discs 30, through the pinions 37 and cams 34. Firing of the missile is effected electrically and the main part 1 of the propulsion gases are exhausted through the vent 38. In an alternative form, Figs. 25, 26, the recoil, acting against the springs 117, rotates the ammunition feed discs 110, through the cams 114. The ammunition belt is driven from the cables 122. The ammunition, Fig. 4, comprises a self-propelled projectile 6, contained in the tube 7, and a firing charge 8, incorporating a firing device 10. The fins 24, mounted at the rear of the projectile, Figs. 13, 14, are urged outwardly by the springs 26 when the projectile leaves the gun. In an alternative form, the fins rotate about axes parallel with the projectile longitudinal axis.
Patent GB-722745-A (GB)
Title: Oximes
Filed: 1952-06-20
Abstract: Aliphatic or cycloaliphatic oximes are manufactured by a process which comprises adding to an acid a mixture of an aqueous solution or suspension of an alkali- or alkaline-earth metal salt of the corresponding primary or secondary nitro compound with a metal capable of displacing hydrogen from the acid.  The metal is preferably finely dispersed.  The nitro comhounds are converted with alkali metal pydroxides or alkaline earth metal hydroxides to the salts.  Nitro compounds mentioned are nitroethane, 1-nitropropane, 2-nitropane, 2-nitrohexane, nitrocyclohexane, 2-nitro-1-methylcyclohexane and 3 - nitro - 1 - methylcyclohexane. Preferred acids are sulphuric, hydrochloric, nitric and acetic acids. Suitable metals include magnesium, aluminium, zinc and iron.  In examples, cyclohexanone oxime and some cyclohexanone and cyclohexanol are produced by dropping nitrocyclohexane dissolved in caustic soda solution with zinc dust into dilute hydrochloric acid (1); acetaldoxime and some ethylamine are produced by dropping a mixture of nitroethane in caustic soda solution with magnesium powder into sulphuric acid (2); and cyclohexanone oxime is produced by dropping nitrocyclohexane in caustic soda with iron powder into hydrochloric acid (3).  In (1) and (3) the pH is adjusted to precipitate the oxime which is filtered off and residual oxime with the other products are extracted from the filtrate with benzene.  In (2) the acetaldoxime and after liberation by addition of caustic soda, the ethylamine are extracted from the reacted mixture with benzene.  Acid is added during each reduction to maintain the pH at or below 1.  The yield of oxime is increased in (3) when more finely divided iron is employed.

An axial-flow fan is mounted on a shaft 5 carried by a bearing housing 7 supported at 8 in the intake channel 1 of an air cushion vehicle. The shaft 5 is driven by an engine 9. A ring 13 closely surrounding the tips of the fan blades 4 is resiliently mounted in a recess 12 by elastic seals 14 and a number of circumferentially spaced rubber blocks 16. The ring 13 may be of glass fibre reinforced plastics and the seals 14 may be of rubber or the like. The ring 13 is secured to the hub by a number of spokes 19, such as steel wires. If any oscillations of the fan relative to the channel occur the ring 13 moves with the fan thereby avoiding striking the blades against the channel wall. Moreover, the seals 14 and blocks 16 provide a damping effect on the oscillations and absorb any torsional loads. The ring can be properly centred in relation to the fan axis and its circular shape adjusted by tightening of the spokes 19, the latter being provided for this purpose, with tapered heads at their outer ends located in tapered bores in adjustable screws. The inside of the ring 13 may be coated and the coating may be machined by the blades to provide fine clearance therebetween. The blade tips may be connected to an annular shroud closely surrounded by the ring 13.

Title: Improvements in or relating to bubble pipes
IPC: A63H33/28
Filed: 1945-06-22
Abstract: 596,814. Bubble pipes. NEUMANN, A. E. June 22, 1945, No. 15994. Convention date, Aug. 23, 1944. [Class 132 (iii)] A bubble pipe comprises essentially a compartment closed at its upper end having an outlet at its lower end adapted to receive bubble forming solution together with a stem opening into the said compartment and a baffle within the said compartment spaced from the top and bottom thereof and extending from the lower wall of said stem substantially perpendicularly to the axis of the said opening or outlet in order to shield the said outlet from a current of air entering the compartment from the stem. In a modification the stem is provided with a second passage opening into a second compartment having restricted communication with the atmosphere and adapted to contain a second liquid, the said second passage being adapted to form a whistle. In the Figure the bowl 6 is constructed with two separate compartments, the upper one 8 containing, say, water and having restricted communication 11 with the atmosphere, and the lower one 9 having the outlet 14 adapted to receive the bubble-forming solution. The outlet is provided with an annular lip 13 with a rounded edge, the two compartments being separated by a partition 7. The tubular stem 16 is divided into two parts by a partition 19, which preferably joins the chamber partition 7. The upper tube 17 forms a whistle, the lower part 18 communicates with the chamber 9 in which is a baffle 20. The upper surface of the stem projects into the upper chamber 8 so as almost to touch the partition 7. Water is poured into 8 so as to submerge completely the opening of the tube. The lower part is dipped into the bubble-forming liquid and on blowing down the mouthpiece a bubble forms on the outlet 14 while the whistle emits a pleasant burbling or trilling sound, the pitch of which can be varied by pressure on one or both of the flexible mouthpiece portions 21 and 23.

Title: Tray storage and handling system for scintillation spectrometers and the like
IPC: G01N21/75
Filed: 1973-04-03
Abstract: 1381070 Sample tray conveyer PACKARD INSTRUMENT CO Inc 3 April 1973 [7 April 1972] 15994/73 Heading G1B [Also in Division B8] Trays 12 containing vials 11 Figs. 1 and 10 are placed manually on pallets 20 of a conveyer Fig. 1. The latter comprises at least two horizontal sets of tracks 21, 22, one spaced vertically above the other (only the upper 22 being visible in Fig. 1). The tracks 21, 22, receive running rollers 30, 31, and 41, 42 of each pallet. At each end of the conveyer tracks is a respective elevator, the platform (23 or 24 as the case may be) of which, is shaped so as to be suitable for receiving a pallet from one or other of the conveyer tracks 21, 22. When the elevator platforms 23, 24, are in their upper positions as shown in Fig. 1 (they are in their lower positions in Fig. 2), a pallet is present on the L.H. elevator platform 23, but the right hand platform 24 is empty. Under those conditions the space on the tracks 21, 22, between the platforms 23, 24, is filled with pallets. A pusher 111, Fig. 2, associated with the left hand end of the upper track 22, is then moved leftwards (as viewed in Fig. 2), and by virtue of its resilience passes under the base of the pallet on the platform 23, and then springs up to engage the left most edge of this pallet. The pusher 111 is then in a position, as its direction of movement reverses, to drive the pallet rightwards and so push the whole row of pallets a distance equal to the length of one pallet. The leading (i.e. most rightwards) pallet, is thereby driven on to the elevator platform 24. Operation of a limit switch then causes both platforms to be lowered to the level of the lower tracks 21. Operation of a further limit switch then initiates the movement of a pusher 60, Fig. 2, similar to the pusher 111 associated with the upper tracks 22. The pusher however is arranged to have an indexing. action so that each row of vials in the pallets on the lower tracks 21 are indexed successively past a transfer station 13. At each such dwell, the vials are removed (by apparatus not described), and are transported laterally to a scintillation counting unit 14 having a vertical counting well 15. By apparatus (also not described) the indexing action is such that, subject to the action of a sensor, if there are no vials present in a particular row of a tray, that row is moved past the transfer station without a stop. In order to correlate data generated for each sample in the counting unit 15, with the location of the sample on the conveyer, each pallet is formed with a pattern of switch actuating lugs (156) Fig. 7 (not shown). These are arranged to co-operate with combinations of a series of switches 150-154, Fig. 6, according to a binary code, as the pallets move along the track 21.

Title: Apparatus for comparing amplitudes at selected points in recurrent electrical signal waveforms
Inventor: WEAVER LESLIE ERNEST
IPC: H04N17/00
Filed: 1961-05-03
Abstract: 949,072. Measuring pulse train characteristics. BRITISH BROADCASTING CORPORATION. May 2, 1962 [May 3,1961], No. 16064/61. Heading G1U. An apparatus for comparing the amplitudes at selected points in a recurrent electrical signal waveform comprises a means for generating sampling pulses of small duration in comparison with the duration of the waveform, the pulses recurring in groups of two or more at the frequency of the said waveform and being applied to sample the waveform, a means for increasing the duration of the pulses constituting the samples without substantially changing the amplitude ratio thereof and means for comparing the amplitudes of the increased duration pulses. The invention is particularly described with the relation to measuring pulse to bar ratio when testing the performance of television equipment. A generator of such pulses P and B (Fig. 2(a)) is indicated at 10, this generator providing also a synchronizing pulse S which is fed to a driving pulse generator 11. This introduces a variable time delay before actuating the sampling pulse generator 12 which generates two sampling pulses, SP1 and SP2, for each synchronizing pulse, the pulses being accurately locked in time, such that the first appears at the peak of the pulse P and the second at the mid point of the bar B. These sampling pulses are of only a few millimicrosecond duration, and are fed to the sampler 13, which is a form of modulator or linear gate, to the other input of which the pulse to bar waveform is applied. The output from the sampler is fed to a pulse stretcher and amplifier 15, which increases the duration of the pulses while leaving the relative amplitudes unaltered (see Fig. 2(d)). The pulse to bar ratio may then be easily measured by displaying the two pulses on a cathode ray monitor, the measurement having been simplified by reducing the band width required (because of the broadening of the pulses). The monitor will be entirely adequate for observing the two amplitudes when it is required to set the pulse to bar ratio to unity. If however some other ratio is required further units, 17,18, may be included in the apparatus, these being triggered from the synchronizing pulse to generate a pulse of calibrated amplitude which is subtracted from the bar pulse in a unit 14. The monitor can then still be used to look for pulses of equal amplitude. Other circuit modifications are mentioned, such as the inclusion of a clipper 22 in series with the pulses so that only the peak areas of them are examined.

Title: Hydraulic systems
IPC: F15B11/08
Filed: 1968-04-04
Abstract: 1,203,365. Fluid-pressure apparatus. FELLOWS GEAR SHAPER CO. April 4, 1968 [Oct.30, 1967], No.16185/68. Heading F1P. A hydraulic piston-and-cylinder assembly 10, which may be employed in a machine tool, has annular grooves 36, 42 connected to a pump 20, reciprocation of the piston being effected by alternately opening and closing a solenoid-operated valve 34 in an outlet pipe 30 on the downstream side of a flow restrictor 32. Reciprocation is ensured by the difference in the effective areas of the ends 38, 40. The effect of the valve 34 can be over-ridden when for example this valve fails to operate, by operating a valve 58 to connect a port 58 to a reservoir 62. Normally, pump pressure keeps a non-return valve 54 shut. A three-way valve may be used in place of the flow restrictor and valve 34.

Abstract: 704,561. Valves. WALKER, CROSWELLER & CO., Ltd. July 14, 1952 [July 12, 1951], No. 16500/51. Class 135 A valve controlling the flow of fluid, e.g. from two inlet pipes 12, 13 leading from either side of a flow orifice to two outlet pipes 14, 15 leading to a measuring instrument comprises a piston 18 slidable in a body bore from an extreme position in which all passages through the valve are closed, through at least one intermediate position where one of the inlets connects with both outlets, to an opposite extreme position where each inlet connects with a corresponding outlet. As shown in Fig. 1, both inlets are sealed from the outlets by the piston sealing rings 20, 21. When the piston is moved to the left so that ring 20 lies between the edges of inlet groove 12a and ring 21, carried by the piston lies on the right-hand side of the groove 15a, the higher pressure inlet 13 is sealed from the outlet 15, but the lower presssure inlet 12 communicates around the piston neck 22 with both outlets. When the ring 21 lies between the sides of the groove 15a and ring 20 lies on the left-hand edge of groove 12a both inlets communcate with both outlets, and when ring 21 lies on the left-hand side of the groove 15a the inlets 12, 13 connect respectively with each of the outlets 14, 15. The piston is moved by a handle 8 screwing at 8a into the end of the piston, the latter being prevented from rotating by a projection 24 entering a casing hole 5. In the extreme closed position leakage along the handle is prevented by a sealing ring 19 engaging the piston bore while the other extreme position leakage is prevented by the ring 20.
