Title: Improvements in or relating to differential fluid pressure motors
IPC: F01C9/00
Filed: 1950-03-09
Abstract: 712,032. Fluid pressure motors; valve gear. O'SHEI, W. E. June 11, 1951 [March 9, 1950], No. 6002/50. Classes 110(2) and 122(2) A motor for actuating a windscreen wiper has means for adjusting the lost-motion between a rocker member or kicker, which actuates the usual snapaction valve mechanism, and the rocker shaft which actuates the kicker. As shown a kicker 11 is actuated alternately by means of radial surfaces 29 on the rocker shaft 5. A sleeve 27 is attached frictionally, by means of a washer 34, to a portion 25 of the arm 11, and is provided with. a portion 28 for co-action with the surfaces 29. A ridge 30, on the sleeve, fits within a recess 31. so as to permit limited angular adjustment between the parts 25. 27. The sleeve is turned by means of a screwdriver, which engages a slot 35, to one or other of its limiting positions to alter the arc movement of the kicker 11 relative to the shaft 5 to produce the desired movement of the vane within the motor housing depending upon the selected parking position of the wiper blade. Means may be necessary to prevent movement of the kicker while the sleeve is being turned. In a modification. the member 28 may be removable from the tubular portion 27 and adapted to be inserted therein in one of two or more positions. One of a number of various sized members 28 may be inserted to suit the arc of travel desired. Tapered screws may be inserted, in a further modification, to co-act with abutments 29 or one tapered screw which is inserted between two wedge members to force them apart. Specifications 557,232. 557,377 and 685,554 are referred to.

Abstract: 1379363 Bogie with damping means WAGGONFABRIK TALBOT KG 7 Feb 1973 [10 Feb 1972] 6005/73 Heading B7L [Also in Division F2] A bogie for a railway vehicle comprises an axle housing 3 which supports the bogie frame through coil springs 5, 5a and is guided by an axial guide 4 for vertical and transverse horizontal movement relative thereto, the springs on one side of the axle being connected directly to the axle guide 4 while the other spring 5 is connected to the axle guide through a plate 7 and a shackle 6, and a slide 9 bears frictionally on one side against the housing 3 and on the other side against a push rod 8 urged against the slide by the plate 7 and displaceable in the axle guide 4, the frictional engagement between the slide 9 and the housing 3 and between the slide and the push rod 8 respectively damping the transverse horizontal and vertical movements of the bogie frame relative to the axles and the coefficient of friction being greater for the former damping engagement. In order to provide different coefficients of friction, friction linings 10, 11 of synthetic material and steel respectively are provided on the axle housing 3 and push rod 8 and/or both sides of the slide 9, and on the other side of the axle a similar slide and friction linings are provided to create the same friction conditions. Flanges 9a and 9b on the horizontal and vertical edges of the slide 9 prevent vertical and horizontal movement respectively of the slide relative to the axle housing and push rod. In an alternative embodiment the slide, flanges and friction linings are so arranged that the vertical friction damping is provided by engagement between the slide and the housing 3 and transverse horizontal damping by the slide and the push rod. Instead of having sliding engagement between the push rod 8 and slide 9, pressure rolls 16 which may be plain or toothed as shown in Fig. 8 may be provided to urge the slide against the housing 3, the horizontal damping being provided by sliding friction between the slide and the housing, and light vertical damping by rolling movement of the rolls 16 on the slide.

Title: Process for the production of urea and ammonium carbamate
IPC: C01B21/12
Filed: 1953-03-09
Abstract: In the production of urea from carbon dioxide, water and excess ammonia under pressure, the vapours produced are expanded and pressure distilled at 20-45 atmospheres pressure, and the resulting carbon dioxide <PICT:0756934/IV(a)/1> and ammonia passed to a condenser at 60-90 DEG  C., which is fed with liquid ammonia and up to 25 per cent water.  Aqueous urea is withdrawn from the pressure still, and the carbamate, which is condensed free from solid particles is returned to the autoclave at increased pressure.  In the Figure, the products from the autoclave 1, which is fed with carbon dioxide through pump 9 and ammonia through pump 11, pass to a pressure still 13 whence the resulting urea solution is collected in a separator 3 and the carbon dioxide and ammonia condensed as carbamate in the chamber 5.  The latter is fed with make up ammonia from pump 11 and an aqueous solution from column 6, which is fed with the minimum amount of water to dissolve the ammonia and carbon dioxide leaving the chamber 5.  The condensate from the latter is recycled by means of pump 10 heated to a temperature higher than the temperature of crystallization of the carbamate.

Abstract: 831,955. Measuring rotor unbalance electrically. PARSONS & CO. Ltd., C. A. May 28, 1957 [March 2, 1956], No. 6585/56. Class 40 (1). [Also in Group XXXVI] The magnitude and phase of the unbalance of a rotor in two bearing planes is determined by measuring the magnitude and phase of the voltage required to reduce the unbalance indications to zero, and are combined with similar measurements of unbalance due to calibrating weights in each of two balancing planes to determine the magnitude and phase of the unbalance in the two balancing planes. As shown (Fig. 1), a rotor a, supported in bearings b, c, has its unbalance detected by inductive pick-ups d, e mounted on the bearing pedestals. A 3-phase generator h is driven with the rotor and supplies the stator of a selsyn unit, whose rotor is rotatable to produce a voltage of the correct phase which is fed via a potentiometer to neutralize the unbalance signal of each pick-up separately, the phase and magnitude of the opposing voltage being indicative of the phase and magnitude of the unbalance at each bearing. With the unbalance voltages thus neutralized electrically, a calibration weight is placed in a known position in balancing plane k and the new unbalance voltages measured as before. This is repeated with the calibration weight in balancing plane n, and the six readings are combined vectorially to determine the magnitude and phase of the unbalance in the balancing planes k, n.
