Patent GB-1380029-A (GB)
Title: Attitude control system apparatus
IPC: E02F3/76
Filed: 1973-03-22
Abstract: 1380029 Graders SYSTRON-DONNER CORP 22 March 1973 [30 March 1972] 13873/ 73 Heading E1F [Also in Division G3]  In a system for maintaining the angle of tilt of part of a machine relative to the horizontal despite movements of the machine as a whole, undesired motion of the said part is detected by a linear accelerometer and by a device responsive to angular movement, the signals from which are combined to control correcting means. As shown, the system controls the blade on an earth scraper but it may also be used for stabilising a passenger compartment suspended in a rail vehicle (Fig. 10, not shown). In the earth scraper application the system controls a hydraulic actuator 47 at one end of the blade, while a similar actuator 46 at the opposite end is controlled by the difference between a reference potentiometer 63 and a potentiometer 67 actuated 'by a feeler in contact with a guide wire; thus the height of one end of the blade relative to the wire is kept constant, and the invention keeps its tilt constant. The desired tilt is entered on potentiometer 87 for comparison with the output of combining circuit 97 to control cylinder 47. As shown, circuit 97 double integrates the output of an angular accelerometer 94 mounted on the blade. The output of a linear accelerometer 93 also mounted on the blade, with its effective direction perpendicular to the tilt axis is compared with the output of 97 at 139 and the difference is fed to 97 via a "bias error corrector circuit" 95. This cancels any drift caused by the double integration of any zero error in accelerometer 94. An RC filter 101, 102 allows short time constant signals during actual movement. A phase lead network 96 ensures stability. The signal from 93 will contain an unwanted component due to accelerations of the machine in the direction of its travel; this is cancelled by the arrangement 82 in which an engine driven tachometer signal 125 is differentiated at 126, or a second linear accelerometer 145 is provided, and the result is multiplied by the sine of the angle the blade makes with the direction of travel. The cosine of this angle is also supplied as a feedback to the circuit 97, to adjust the integrated output of 94 for this angle. (The blade must be tilted by a different amount to achieve a desired resultant tilt if the blade is not perpendicular to the travel direction). The circuit 97 also has a low pass filtering action, to remove effects of machine oscillation due to flexibility of its tyres, &c 88 is an indicator. In a simpler system (Fig. 12, not shown) the angular accelerometer is replaced by an angular rate sensor and only single integration is required.

Title: Improvements in or relating to railway waggon axle assemblies
IPC: B61F7/00
Filed: 1963-04-08
Abstract: 1,038,373. Changing gauge of wheels. F. M. AZA. April 8, 1963, No. 13937/63. Heading B7L. [Also in Division E1] A railway wagon wheel R, Fig. 1, at each end of a common axle E, is axially displaceable thereon to change the gauge by track means G, G<SP>1</SP>, Fig. 3, and is locked in each of two positions shown by pivoted pawls 2 carried in a sleeve-disc member 1 secured on the axle and having slidable thereon a ring 3 operable by track means D, E and D<SP>1</SP> to release the pawls from a hub portion 5 of the wheel. The wheel hub portion 5 has uniformly spaced keyways 8 slidingly engaging keys 7 secured to the sleeve-disc 1 and the pawls 2 are uniformly spaced between the keys. The pawls 2 are rocked in an annular recess in the disc 1 when the ring 3 slides thereon against the action of springs 6. A ring 4 secured on the axle E limits the outward movement of the wheel whose inward movement is limited by the sleeve-disc 1. The gaps between the wheel and ring 4 and the disc 1 are covered by elastic elements Z and Y, and oxidation between the sliding surfaces of the wheel and axle is prevented by metallizing one of the surfaces or by using bushes of antifriction material or plastics. Referring to Fig. 3, A is the broad gauge track; B the narrow gauge track; C is a raised track engageable only by the discs 1 to lift the wheels R from the track A or B; D, E and D<SP>1</SP> are guide rails with appropriately shaped terminations to coact with the ring 3; and G, G<SP>1</SP> are guide rails appropriately shaped to coact with the raised wheels R. Assuming the wagon is moving along the track A, the discs 1 engage the raised track C to lift the wheels R from the track A. As the wagon is moved along the track C the rings 3 engage the left-hand terminations of the rails E to cause the rings 3 to move inwardly towards each other and release the pawl ends from the hub portion 5. The wheels then engage the right-hand rails G<SP>1</SP> and are caused to move inwards towards each other. Finally, the rings 3 engage the right-hand rails D<SP>1</SP> and are returned to the position shown in Fig. 1, to grip over the hub portions 5. As the discs 1 leave the rails C the wheels R now in positions R<SP>1</SP> engage the track B. If a wagon moves from the track B to the track A, similar operations are effected by the appropriate guide rails. According to modifications the keys may be secured to the wheel hubs and engage keyways in the disc members 1 or as described with reference to Fig. 2 (not shown), the keys which are longer than those of Fig. 1, engage in holes in the wheel and the pawls also pass through holes in the wheel. Brake shoes follow the displacement of the associated wheel by means of a slidable fork-piece 9, Fig. 1, solidly fixed to the brake shoe support and extending over the wheel rim without touching the rim. The shoe support coacts with a double acting detent 10 actuated by two springs.

Title: Improvements in and relating to a method and apparatus for filling containers with liquids
IPC: B67C3/10
Filed: 1966-03-30
Abstract: 1,147,341. Bottling. ENZINGER-UNIONWERKE A.G. 30 March, 1966 [31 March, 1965], No. 14016/66. Heading B8T. In rotating-table apparatus for charging carbon dioxide-containing liquids into bottles &c., pressurized gas is firstly introduced to the bottle 25 through a conduit 39 from a chamber 7, when the bottle is pressed upwardly by a support 27 into sealing engagement with a head 24. When the required pressure is attained a valve 35 is closed, and a valve 51 is opened to allow the filling liquid to flow into the bottle from a reservoir 5 through a pipe 28. The gas forced from the bottle by the inflowing liquid passes along a conduit 52 and past a float valve 54, 57 and a non-return valve 63 to enter a chamber 4. The float valve 54, 57 comprises a ball resting on a castellated support, Figs. 3, 4 (not shown), which permits passage of gas in either direction. In place of the castellated support the float valve may have a permeable lining below the bore in which the ball floats. When the level of liquid in the bottle 25, Fig. 7, rises above the delivery end of the pipe 28 a valve 70 above the float valve 54, 57 is opened to vent the gas to a vessel 31 through a throttle aperture 73, and thence to atmosphere. The size of the throttle aperture 73 may be adjustable. The internal pressure in the bottle 25 is thus reduced and the non-return valve 63 closes under the action of the excess pressure in the chamber 4. The filling of the bottle 25 then proceeds at an enhanced rate, due to the decreased pressure within the bottle, until the liquid rises into the conduit 52 and closes the float valve 54, 57 by floating the ball of the valve up into engagement with a seating at the top of the valve. The valve 51 then closes, stopping the filling process, and the bottle is lowered on its support 27, out of engagement with the head 24, the residual gas in the bottle escaping as the remaining liquid in the conduit 52 flows into the bottle. Control of the valves 35, 51 and 70 is by tappets 19, 20 and 21 operated through a crank-shaft by a star-wheel (17), Fig. 1 (not shown). Liquid is drawn from the reservoir 5, Fig. 7, through a pipe 11, which includes a valve whereby supply of the liquid is cut off in the event of leakage due to a bottle bursting &c. The head 24, together with the filling pipe 28 and the valve 51, may be dismantled from the apparatus to facilitate clearing and sterilization.

Abstract: 499,248. Automatic firearms. GENSCHOW & CO. AKT.-GES., G. May 12, 1938, No. 14216. Convention date, May 31, 1937. [Class 119] The speed of firing of an automatic firearm is governed by a pneumatic brake 7 located below the barrel or chamber 4, the brake comprising a piston 13, Fig. 6, coupled to a slide 20 which is guided on the brake cylinder 7 and carries a pivoted pawl 10 adapted to engage a reciprocating part of the mechanism, e.g. the lock or part of the lock or, where the barrel reciprocates, the barrel or a tube fixed thereto. The pawl is spring-pressed so as normally to project to engage the reciprocating part of the mechanism, thereby slowing down the firing speed by the dashpot effect of the brake 7, the dashpot cylinder having fixed apertures at one end and an adjustable aperture at the other so that the speed may be controlled. The axis of the cylinder, and the parallel slide 20, are inclined to the barrel, so that the pawl is automatically disengaged from the reciprocating part of the mechanism during the forward movement of such part. The pawl has a pin which may be engaged by a surface on a slide controlled by a handle 27 so that the pawl may be rendered inoperative if required.
