Patent GB-547021-A (GB)
Title: Improvements in or relating to the control of variable-pitch airscrews
IPC: B64C11/44
Filed: 1941-04-30
Abstract: 547,021. Automatic control systems for variable pitch airscrews. BRISTOL AEROPLANE CO., Ltd., THOMAS, F. M., and PRICE, P. R. April 30, 1941, No. 5624. Drawings to Specification. [Class 38 (iv)] Pitch relationship is maintained automatically between two or more air screws, which are so driven as to maintain a given speed relationship, notwithstanding pitch adjustment to maintain constant speed. Governor controlled pitch adjusting mechanism for a number of such air screws is combined with means responsive to a change in the predetermined relationship between the pitches of the screws whereby (1) in the intervals of governor-controlled adjustment the pitchadjusting motors are actuated simultaneously in opposite senses to correct the relationship or (2) during a governor control impulse the faster pitch-adjusting motor is slowed or stopped to effect the correction or (3) both arrangements are combined. Manual means may also be provided for joint and individual operation of the pitch adjusting motors and for feathering any screw. An electrical method of control is described applied to electric pitch-adjusting motors but other motors may be used. Each air screw has a rotary contact element coupled through speed reducing gearing, to one air screw blade, and a co-operating brush carrier driven through speed increasing gearing from the air screw shaft A conducting segment of 120 degrees on one contact element co-operates with two segments on another, each segment covering one of the other 120 degrees. The co-operating brushes selectively energize one of two pitch correction circuits when the desired relationship is departed from. The duration of the resulting intermittent correcting impulse varies with the extent of departure up to a maximum corresponding to about 120 degrees of brush movement on the segments but a maximum impulse which is substantially continuous may be obtained by using three sets of brushes or segments each 120 degrees displaced from the others. The impulses may energize (1) electromagnetic relay switches interrupting the circuits between the adjusting motors and the governor actuated switch and substituting an adjusting impulse through the relay ; (2) relays with. two contacts controlling respectively a resistance in series with the adjusting motor and a contact opening the motor circuit after a time delay or (3) a neutralizing winding to annul the effect of the governor actuated switch in closing a relay in the adjusting circuit of the fast running motor and also energizing a further winding on the same relay to cause its closure in the intervals of governor impulses if the air screw pitches are not of correct relationship. In a modification the brushes are fixed on the air screw hub and the segments are in the hub and driven by suitable gearing from the pitch-adjusting motor. Pitch indicators may be included.

Title: Improvements in or relating to the cold working of metal
Inventor: KAUL BEN
IPC: B21C23/03
Filed: 1956-02-24
Abstract: 806,387. Making cupped articles; extruding. AMERICAN RADIATOR & STANDARD SANITARY CORPORATION. Feb. 24, 1956, No. 5727/56. Classes 83 (2) and 83 (4). A method of cold forming a cup-shaped steel article 72, Fig. 7, having an internal shoulder 76 and a thin terminal wall 71, comprises backwardly extruding the upper portion of the wall 50 of a cup-shaped blank 47, Fig. 5, to produce the thin wall 71. A disc-shaped blank of up to 0.4 per cent carbon steel, which may be a scrap slug from a punching operation or may be cut from bar stock, is pressed in die cavity 5, Fig. 3, by a punch 16, having a flat or slightly crowned end 20, to form a sized blank 24 of reduced diameter having a concavity 26 caused by radial compression of the metal due to a die shoulder 10 which closes the grain structure of the blank. The latter has an upper flatbottomed recess 21; work-hardening is effected on the flat surface 21 and on the lower side wall of the blank. The latter is ejected by a member 14 and inserted in a second die 29, Fig. 5, where it is backwardly extruded by a nose-ended punch 39 to produce a cup-shaped blank 47 work hardened on its portions 48, 49, 45 and having an upper annular shoulder 53. The blank 47 may be formed in a two-stage operation with intermediate annealing, normalising, pickling, washing and bonderizing. After ejection by a member 37, the blank is drawn through a die 57, Fig. 7, by a punch 65 to first elongate the blank until its shoulder 53 engages an abrupt shoulder 67 on the punch, whereupon the wall of the blank is backwardly extruded between the punch shank 66 and the parallel bore 60 of the die to form the thin wall 71. As the punch shoulder 67 passes through the die bore 60, the backward extrusion changes to drawing and finally the blank 72 passes completely through the bore 60 where the relaxation of compression causes a slight enlargement in diameter which enables the blank to be stripped from the punch, as the latter is withdrawn, by engagement with die shoulder 61. The blank 72 has now been work-hardened on its wall 73. This blank may constitute the finished pressed article or the thin wall 71 may be closed in by a nosing punch 80, Fig. 9. Alternatively, the thin wall may be flanged outwardly to form a flanged member 86, Fig. 16 (not shown). Subsequently, the pressed article may be threaded internally and undercut adjacent its closed end to form a hollow plug, Fig. 15 (not shown). Alternatively, the article may be threaded externally. Annealing or normalising may take place between successive pressing operations and final stress relief heating at 750‹ F. before or after the nosing operation of Fig. 9. Die lubricants are used and the blanks are bonderized or provided with a phosphate coating before each pressing operation.

IPC: G01F1/76
Filed: 1960-02-22
Abstract: 904,311. Fluid-pressure servomotor-control systems. AVERY-HARDOLL Ltd. Feb. 8, 1961 [Feb. 22, 1960], No. 6179/60. Addition to 857,348. Class 135. [Also in Group XXVI] A liquid meter having a rotor driven by the flow of liquid and thereby giving an indication of the volume flow has additionally means for indicating the weight flow driven through variable speed friction gearing the ratio of which is adjusted in dependence upon the density of the liquid. The arrangement is similar to that of the parent Specification (Group XXVI) in that it comprises a float chamber 36 through which a portion of the liquid upstream of the meter is diverted and of which the float 57, pivoted by pins 59 mounted in bearings 61, actuates valve members 127 controllling four nozzles, two of which are shown, whereby a piston 46 is operated. Movement of the piston alters the ratio of the variable friction gearing (not shown) through a rack and pinion 55, 56 and also moves counter-weights 71 for the float so that the float and piston are caused to oscillate about a mean position corresponding to the density of the liquid. The improve ment lies in the provision of a relay piston valve (not shown) between the nozzles controlled by the valve members 127 and the piston 46 whereby a tendency for the float and the piston 46 to come to rest at or near the mean position is overcome. The embodiment described also differs from disclosure in the parent Specification by the formation of the piston in two relatively slidable parts of which the inner part 50 is connected with the counter-weights and slides between stops (not shown) in the outer part which carries the rack 55 and has a sealing ring 49 which also provides frictional resistance to movement of the outer part.
