Abstract: 687,135. Gyroscopic apparatus. METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. April 4, 1950 [Feb. 17, 1949], No. 4394/49. Class 97 (iii). [Also in Group XXXII] A gyroscopic apparatus provided with a resilient mounting 17, Fig. 1, has the gyroscope as a whole statically balanced about two perpendicular axes, the mounting 17 having neutral axes coinciding with the balancing axes so that linear vibration will be transmitted to the gyroscope through the resilient mounting solely as linear movements. In a rate of turn gyro the rotor 1 is mounted in a gimbal 2 which is pivoted in bearings in end plates 5, 6, the latter forming with a pair of plates such as 8, an open ended box. Plates 5, 6 are bolted to supporting plates 14, 15, recesses 12, 13 therein, receiving spigots 5a, 6a, on the end plates. In balancing the open-ended box about axis B-B it is spun in a dynamic balancing machine provided with centres to which the plates 5, 6, are bolted and recessed to receive the spigots. Similar spigots such as 8a are provided on the side plates for balancing about a perpendicular axis. Adjacent each plate 14 and symmetrically arranged around the axis B-B, are four rubber cushions 17 bonded to metal plates 18 rigid with plates 14, 15, and bonded to plates 19 which have screw-threaded bores for receiving bolts 20 passing through the casing 16. When the supporting craft turns about an axis perpendicular to both the gyro spin axis and axis B-B, the gyro precesses about the latter axis under the control of spring 10, an electromagnetic pick-off 9 indicating the precession. Two pairs of dashpot cylinders 25, 25a, mounted on plates 26, 27, secured between the plates such as 8, provide damping about the axis of turn. The plungers in each pair of dashpots are connected by stiff flexible wires 28, 28a, extending through diametral holes in bolts 29, 29a, and secured thereto by nuts and washers, the bolts 29, 29a being rigid with lugs 30, 30a secured to the casing 16. Diametrically opposite dashpots may be connected by conduits to prevent linear damping along the axis B-B. Vibration of the gimbal 2 is damped by a device 11 comprising an annular casing 39, Fig. 3, secured to plate 5 having blocks 44, 45, fastened by screws 46 to its inner surface. Resilient bellows 47, 48, 49, 50 extend between the blocks and the arms of a metal member 40 fast on the shaft 43 supporting gimbal 2. The bellows 47, 48 and 49, 50 which contain oil, silicone or other damping fluid are connected by passageways 51, 53, in the blocks, needle valves 52, 54, controlling the damping, whilst bellows 55, 56, secured to the blocks and connected with the passageways allow relief of excessive pressure. Passageways 59, 60 may be provided in the member 40 for connecting diametrically opposed bellows for pressure equalization in the event of unequal adjustment of the needle valves. In the embodiment described in the Provisional Specification the dashpot cylinders are mounted in the end plates.

Abstract: 565,737. Purifying sulphuric acid ; oleum ; drying sulphur dioxide. DU PONT DE NEMOURS & CO., E. I. March 22, 1943, No. 4623. Convention date, March 21, 1942. [Class 1 (ii)] A method for fostifying chamber acid or like lead-containing sulphuric acid in conjunction with a contact sulphuric acid process, comprises scrubbing cold moist burner gases with said acid, whereby it is diluted and lead sulphate precipitated, separating the precipitate and - utilising the treated acid to absorb sulphur trioxide produced by conversion of the dried burner gas. As shown in the Figure, burner gases passing to the contact chamber 17 are scrubbed in towers 14, 15, 16, through each of which the drying acid successively circulates in countercurrent, the strength decreasing from 66‹ BÚ at the inlet 22 to about 48‹ BÚ at the outlet 9. The lead sulphate settles in tank 10 and the acid is fed to the absorber 19 where it is fortified to 98 per cent, and then to the oleum absorber 18. Alternatively, it may be wholly or partly fed direct to the latter. In a modification, where the acid to be treated is not so strong, acid from the 98 per cent absorber may be used for the final drying step, being returned to the 98 per cent absorber. In another modification, the lead-containing acid may be dripped into any or all of the circulating systems. The invention may be applied to the pre-drying of air for use in preparing sulphur dioxide by burning sulphur.

Title: Colour printer
IPC: G03B27/73
Filed: 1963-02-05
Abstract: 1,031,248. Colour printing. PAVELLE CORPORATION. Feb. 5,1963 [Feb. 6,1962], No. 4664/63. Heading G2A. [Also in Division G1] The colour of the printing light is adjusted by the filter wedges 18 and 20 Fig. 6 which shade from dense cyan to dense yellow and dense magenta to dense yellow respectively with clear areas at their centres. The photo resistors 24, 26 are connected in a bridge circuit 40 Fig. 5 (not shown) which, when balanced indicates the correct balance between the blue light passing through filter 28 and the green or red light passing selectively through filter 30<SP>1</SP>. The filter wedges are adjusted until balance is achieved. The resistors 44, 46 in the bridge are initially set by balancing the bridge with a standard negative, and the printing light colour balance required for a grey print therefrom. The exposure required for each print is measured by a second bridge including the photoresistor 72 provided with a panchromatic filter 73. The aperture of the lens 16 is allowed for by the grey wedge 74 in front of photoresistor 72, and the lens to emulsion distance by the photoresistor 80 illuminated by a lamp 84 along a blackened tube 86. The bridges are supplied from an A.C. source rectified at 60 and are protected by a neon lamp 68 and which prevents the full rectified voltage being thrown across the photo-resistors when in a high impedence condition. A simplified embodiment is described with reference to Figs. 1 and 4 in which photoresistors 72 and 80 are omitted, and the filter 30 has an extra panchromatic segment so that the photoresistor 26 can replace 72. The apparatus may be readjusted for a new emulsion by the following steps: (a) The bridges are balanced with no negative. (b) A print-print A-is exposed on the old emulsion and processed. (c) Print A is used as negative to produce a print on the old emulsion print B. (d) A print C is produced from the print A on the new emulsion. (e) Print C is located in the negative carrier and the bridges again balanced. (f) If A is then used to make another print it will approximate to grey, and if it is then used in the negative carrier to rebalance the bridges an even nearer approximation to the correct colour balance for the new emulsion results.

Abstract: 470,581. Fluid - pressure brakes. DUNLOP RUBBER CO., Ltd., WRIGHT, J., and TREVASKIS, H. Feb. 19, 1936, Nos. 5012 and 30592. [Class 103 (i)] [Also in Group XXXIII] In hydraulic braking and steering apparatus particularly for aircraft, by which equal or unequal pressures can be applied to two brakes or groups of brakes by the operation of a pair of pressure reduction valves in each of which the brake operating pressure reacts upon a spring the compression of which determines this pressure, each valve comprises an openended piston provided with ports adapted to register with ports in the valve casing. A pair of valve casings 24, 25 are connected by a bridge piece 39 forming part of a fixed base 40. Each valve device comprises a piston slide valve member 27 having a tubular end provided with ports 28 adapted to register with supply and exhaust ports 31, 34 connected to pipes 2, 4, 22, 23. Pipes 10, 11 connect with the brakes directly or as shown by stepdown pressure transformers 12, 13. A spring 36 bears on the piston 27 and a slidable cup 37, each cup being connected by a pair of links 41, 42 to pins 44, 45 secured to a member 47 guided between plates 53, 54 for radial movement with respect to a member 58 which can be turned about a shaft 65 on the base 40 by the rudder bar 20 through link 21 and arm 61. The plates are slotted at 55, 56 for the pins 44, 45. The member 47 is connected by a chain 50 and cable 7 to a finger lever 8 which may be mounted on the chief flying control 9. Each pressure transformer 12, 13 comprises a piston 67 subject to the pressure in the pipe 10 or 11 and connected to a larger piston 69 which transmits the pressure through pipe 18 or 19 to the brakes. When the pistons are in the normal position shown, the rod 75 of a valve 74 engages the end wall of the small piston chamber 72 to open the valve to connect chamber 79 through chamber 80 and pipe 14 or 15 to a supply reservoir 17. The arrangement permits of the use of a vegetable oil in the brakes and chambers 79, 80 and mineral oil in the other parts of the system. A passage 81 connects the chamber 72 with the atmosphere. Springs 83 retract the piston 69. With the rudder bar 20 in the normal position, operation of the lever 8 applies the brakes equally, the member 47 being moved along the line X X Fig. 2, so that the valve springs 36 are equally compressed by the links 41, 42. If then the rudder bar is deflected the member 58 is turned, the links of one valve are advanced and those of the other valve retracted so that the brake application is increased on one side of the machine and reduced on the other side.

Abstract: 957,568. Weighing apparatus. W. & T. AVERY Ltd. Feb. 7, 1963 [Feb.10, 1962], No.5192/62. Heading G1W. Relates to an automatic feed weigher comprising a material feed means a flow control valve 16 controlling the feed, which may be a liquid, to a weigher, (not shown), apneumatic switch(es) S1, S2 responsive to a predetermined position of a weight responsive part (flags F3 & F4 fixed to an indicating pointer P) corresponding to a required weighment, a manually operable pneumatic valve 3 for initiating operation of the feed and weighing cycle and connected to the weight responsive switches S1, S2 in such a manner that the valve 3 only responds to manual operation when the weight responsive switch S1 or S2 is conditioned to close the flow control valve 16. Tare adjustment. Due to the tare weight of a weigh container (not shown) the pointer P will not be at zero. Pneumatic pressure jet type switches Sa, St which are provided are adjusted to be operated by flags F1, F2 on the pointer at very small departures of the pointer from zero. One or other of these switches thus operates a circuit incorporating valves 5, 6 and air volume control valves 7, 8 to energize a taring motor M1, M2 to cause it to rotate in the appropriate direction to vary the tension in a spring resistant R until the pointer P returns to zero whereupon the motor is stopped. Main and dribble feed. When taring is completed valve 5 causes pilot valves 12,13 to be actuated through shuttle valves 10, 11. This allows an air supply to pass from the manual starter valve 3 to pressurize air cylinders 14, 15 controlling the feed flow valve 16 so as to open it completely and liquid flows to the container. The switch S1 is set to operate before the correct weight is reached whereupon it de-energizes valve 12 to stop the air supply to cylinder 14 thus reducing the opening of valve 16 and providing a dribble feed. When the correct weight is reached switch S2 operates causing valve 13 to cut off air to the cylinder 15 and the feed flow valve 16 closes completely. The manually operated valve 3 cannot affect the feed flow valve 16 unless the switch S2 has already been conditioned to close off the valve 16. Specification 896,931 is referred to.
