Title: Improvements in and relating to hydraulic buffers
IPC: B61G9/08
Filed: 1949-11-04
Abstract: 713,318. Hydro-pneumatic shock-absorbers; railway-vehicle buffers. FITZJOHN, A. P., TURTON, PLATTS & CO., Ltd., G. Nov. 1, 1950 [Nov. 4. 1949], No. 16260/53. Divided out of 713.242. Classes 103(5) and. 108(3) The invention relates to hydraulic buffers, of the kind having an impact-receiving member 44, Fig. 1, operable in the buffer casing 14 in association with piston and; cylinder units in which hydraulic fluid ismaintained under load by air pressure. According to the invention, the piston 12 is orificed and co-operates with a member- 31 for affording progressively-increasing resistance to the displacement of fluid' through the orifice on relative inward movement of the member 44, whereby a resistance is set up in the fluid which is greater than the air pressure acting on the fluid, while on the recoil stroke the plunger is subjected to less than the full force of the air pressure. An air chamber 20 is connected by a pipe 21 with a bore 29 of the. piston 12. The member 31 has tapered grooves 32. In a modification of the chamber 20, Fig. 4 (not shown), the pipe 21 opens into the chamber 20 through a plurality of orifices. In a further modification, Fig. 5 (not shown), the tapered grooves 32 on the member 31, are dispensed with and the bore 28 is tapered. In operation, compressive load on the buffer head 44 drives liquid from the cylinder 10 into the bore 28 and against air pressure in the chamber 20. The grooves 32 progressively increase the damping action. In an alternative construction, Fig. 2, the piston 12 is rigid with the buffer head 44 and the cylinder 10 is rigid with the casing 14. On compression, liquid is dsplaced from the cylinder 10 into a bore 45 of the piston and thence to a space 48 within the buffer plunger 11. Compressed air is contained in the plunger 11 above the space 48 at 50.

Title: Improvements in or relating to calculating mechanism
IPC: G06G3/00
Filed: 1941-12-26
Abstract: 578,914. Bombing sights. BARNES, J. W., and COULTHARD, W. H. Dec. 26, 1941, No. 16688. [Class 92 (ii)] [Also in Group XIX] Relates to a calculating mechanism for use in solving simultaneous equations of the form XY=N1 and X(Y+C)=N, where N1, N2 and C are known quantities. The mechanism as described is primarily intended' for the evaluation of the speed of two relatively moving points one of which is observed from the other such determinations being necessary in gunnery calculations, e.g., bomb-sighting and release, and searchlight control. In the diagram Fig. 1, an aeroplane at A is flying in the direction of the arrow at height H, C is a point of reference whose speed V relative to the aeroplane is to be determined, T is the time taken for the aeroplane to fly from A to a point vertically above C, AC is the sighting line or slant range R. The values of V, T, H and b the angle of sight are connected by the relationship VT=H tan b. If the observer is at the point C and the range is employed VT=R Sin b. In the form of apparatus shown in Fig. 2, a set of logarithmic cams 10, 12 and 14 operate followers 11, 13 and 15. Between the followers 11, 13 is a toothed drum 20 on a floating spindle longitudinally movable in grooves (not shown). On the spindle is a second drum 21 engaging the follower 15 and a fourth follower 17 operating a logarithmic tangential cam 16. If the cams 10, 12 and 14 are set to represent the instantaneous values of T, and selected values of V and H respectively the movement of the cam 16 represents the angle b. Initial setting of the cam 10 is effected by a hand wheel 30 through a differential gear 28. During an observation the value of T changes at a constant rate and to drive the cam 10 at a constant speed the differential gear is driven by, a constant speed motor 25. If, by reason of the initial setting, the sighting line associated with the cam 16 deviates from the point of reference an additional setting is imparted to the cam 10 by the hand wheel and to a further cam 18 through a clutch member 33. The cam 18 through a follower 19 and toothed roller 23 transmits a movement to the follower 13 to maintain the product TV constant. During this second adjustment the spindle of the roller 23 is locked but normally the spindle is free for longitudinal movement and the clutch 33 is open. The cams 10 and 18 are connected by spring means 34 so that as long as the spindle of roller 23 is free to move cam 18 will follow the movement of cam 10. An indicator may be associated with the cam 12 to give a reading of the true relative or ground speed. The cam 14 may be coupled to an altimeter so that it can be set for the true height. In association with a bomb sight the mechanism may be employed to operate a switch or relay to actuate the bomb release mechanism when the angle b reaches a value dependent on the correct ground speed. For predictor apparatus and searchlight control apparatus the range value R is used instead of the height H and the cam 16 is formed as a logarithmic sine cam.

Filed: 1970-04-09
Abstract: 1284332 Programmed sequential control systems SIM-CHEM Ltd 19 April 1971 [9 April 1970] 16871/70 Heading G3N In a control system for a chemical plant having say sixty-four valves V whose settings require adjustment periodically, a computer C is programmed to repeatedly sense in turn each of a plurality of conditions determined by the settings of respective valves and to give a digital output quantifying the required setting for each valve in turn. The computer output is applied via a digital/ analogue converter D/A to a bus-bar b. The bus-bar selectively feeds, via switches S, eight set/hold amplifiers S/H the electrical output of each of which is converted to fluid-pressure signals by a respective current/pressure transducer IP. Each transducer feeds a respective pneumatic line P. Eight pneumatic pressure actuated setting means A, one to each control valve V, are connected respectively to each line P, via solenoid operated valves X and volume booster relays R. The first eight digital outputs in any control cycle correspond respectively to the first valve V in each group, the second eight to the second valve V in each group and so on. Switches S are actuated at instants in each control cycle such that any consecutive set of eight analogue signals are respectively fed in sequence to the eight set/hold amplifiers in turn. After any one amplifier receives a signal, there is an interval whilst the other seven are fed, during which interval a normally closed solenoid valve X of the group coupled to that one amplifier, is opened, preferably by a signal from the computer, to update the setting of a respective control valve. Thus the valves X are opened in turn connecting respective setting means A to line P at the appropriate instants. The settings of all sixtyfour valves are updated in the same sequence as the digital output from computer C.

Title: A process of obtaining pure additive compounds of sulphate of aluminium from impure solutions of aluminium salts
IPC: C01F7/748
Filed: 1937-06-18
Abstract: Pure additive compounds of aluminium sulphate with water and sulphur dioxide, sulphur trioxide, nitrogen trioxide, or nitrogen tetroxide are obtained by subjecting to crystallization a concentrated impure solution of aluminium sulphate containing at least one third mol. of one of the above-mentioned gases per mol. Al2O3.  In a modification, an impure solution of nitrate or sulphite or aluminium is converted to sulphate by sulphur trioxide, and the additive compounds are formed by the liberated nitrogen oxides or sulphur dioxide.  The sulphate solution may be saturated with the gas in a closed vessel under pressure, or less advantageously at atmospheric pressure, or a solution of the gas in water or acid may be added to the solution. Crystallization is effected with agitation, and if heat is developed, with cooling, and towards the end of the crystallization the temperature must not exceed 35 DEG  C.  The crystallization process may be repeated if a very pure product is desired.  Pure sulphate of aluminium may be obtained by heating the additive compounds to 120-200 DEG  C. or by washing the crystals with cold water.  The Specification as open to inspection under Sect. 91, comprises also the preparation, by similar means, of an additive compound of aluminium sulphate with hydrogen chloride.  This subject-matter does not appear in the Specification as accepted.

Abstract: 386,315. Microphones. LANGTON, C. C., 7, Richmond Gardens, Hendon, London. June 12, 1931, No. 17083. [Class 40 (iv).] Light from a source 1 is passed through a collimating lens 2 to a glass block 3 which divides the incident beam 4 into two beams 5, 6 which pass through apertures in a diaphragm 7 and through glass plates 8, 9. The beams after passing through apertures in a second diaphragm 10 fall on a glass block 11 and are recombined to form a single beam 12 which after passing through diaphragm 13, prism 14, and a lens system 15 is focussed on to a slit in a screen 16 behind which is a photo-electric cell 17 connected to an amplifier. In the path of the beam 5 is a stiff-walled tube 18 which protects the air inside from outside disturbances. Changes in pressure due to sound impulses in the air within the tube 18 relatively to the surrounding air, or in the latter when the pressure of air in the tube is kept constant, will cause variations in the order of interference in the recombined beam: The division of the original beam may be produced by a lens close to a diaphragm with two apertures, also a prism may be placed between the lens 2 and the block 3. The amplifier may be connected to.a loud-speaker or the cell may be connected to an amplifier which controls an optical: recording device such as is commonly used in the production of talking films.
