Title: Improvements in Combustion Product Engines.
Inventor: WEIDKNECHT AMEDEE
IPC: C10C1/20
Filed: 1917-09-15
Abstract: 129,303. Weidknecht, A. Sept. 15, 1917. Combustion-product engines.-In a radial-cylinder engine, expansion cylinders alternate with others which compress explosive mixture into explosion chambers from which burnt gases are delivered to a reservoir for supplying the expansion cylinders. The invention is shown in Fig. 2 applied to the rear wheel of a motor-cycle. The cylinders rotate with the wheel about a crankshaft f which is normally held stationary by a pin engaging a recess in a collar 4, the pin being raised to free the crank-shaft, thus putting the engine out of action and enabling the rider to use the pedals to propel the cycle. The cylinders a<1>, a<3>, which alternate with expansion cylinders (not shown), each induce combustible mixture from a carburettor P through passages o, u and a non- return valve t, and, during compression, transfer the charge through a valve w to an expansion chamber v, from which the burnt gases are delivered through a valve z into a reservoir 1 communicating with the expansion cylinders through a non-return valve (not shown).

Abstract: 754,967. Transversely stretching webs. ROBERTSON, J. D. May 7, 1954, No. 13432/54. Class 100 (1). A roller 10 for transversely stretching and contracting web material has a flexible surface sleeve 34 engaging roller sections 28, 30, an axle on which the sections 28, 30 and sleeve 34 are rotable comprising a plurality of flexible leaves 18, 19, 20, 21, 22, 23, 24, 25 and 26 secured together along a portion of the axle to provide a straight rigid axle portion, a bowing device on one end of the axle which effects relative movement of the leaves to impart curvature to the axle and sleeve 34, and a locking device for maintaining such curvature. As shown, the sections 28, 30 have ball bearings 32 the inner races 32a of which fit closely around the leaves 18 ... 26 which are stacked to provide a hexagonal cross-section. The outer races 32b of the bearings 32 are a force fit within the sections 28, 30 and engage abutments 28a, 31, the bearings being spaced apart by sleeve 38 having bevelled ends. The leaves are welded or brazed together to form a rigid portion 42. The leaves 18 and 26 project beyond the intervening leaves, the leaf 18 being secured at 45 to a plunger 44 slidable in a member 46 secured to a sleeve 48, while the leaf 26 is secured at 49 to the member 46. A screw 52 is threaded into the member 46 to engage the plunger 44, while a screw 54 extending through the screw 52 locks the screw 52 in adjusted positions. The sleeve 48 is slidable in a spherical member 82 adjustably secured within a clamp body 84 by screws 16 (Fig. 4, not shown). The roller is mounted at one end in a member 60 pivoted to a ring 68, secured by screws 16 (Fig. 5, not shown) within a clamp body 72. The roller 10 may be bowed by releasing the clamp screws 16 (Figs. 4 and 5, not shown) loosening the locking screw 54, screw 52, and a nut 78 on the opposite end of the leaves. Inward screwing of screw 52 causes inward movement of plunger 44, thus causing leaf 18 and so other leaves to bow. The locking screw 54 and nut 78 are retightened. The clamp screws are tightened when the axis of the roller has been positioned in a desired plane. In a modification, Fig. 8 (not shown) the roller has rigid portions at each end formed by securing the leaves together. In this case, some of the leaves do not extend over the whole length of the roller, the longer leaves having spacer leaves extending over the central flexible part of the roller. In a further modification, the roller has a locking and a bowing device at each end. Specification 736,674 is referred to.

Abstract: 474,629. Bearings. SPERRY GYROSCOPE CO., Inc. May 14, 1936, No. 13713. Convention date, May 14, 1935. [Class 12 (i)] [Also in Group XX] At least one of the angularly movable elements of a gyroscopic instrument is peripherally supported by an air film maintained between co-operating surfaces which permit angular movement only about the desired axis. In the gyro vertical shown the gyro casing 11 has a peripheral channel in which a two-part ring 10 is loosely but closely fitted by set screws so that when air is applied between the co-operating surfaces a circumferential air bearing supports the casing 11 for rotation about a fore and aft axis. The ring 10 is pivoted on ball bearings about a transverse axis in the hemispherical outer casing 1. The rotor 16 with vertical spin axis has upper and lower spherical concavities of different radius of curvature between which and cooperating buttons 15 and 21 air is supplied to form air flotation bearings. A pendulum 26 controlling tangential air jets for providing erecting torques has upper and lower spherical buttons 25, 28, which have different radii but a common centre of curvature and cooperate with concavities fixed to the casing 11 to form a universal air flotation mounting. Air is continuously withdrawn from the casing 1 and is replaced by air entering through one of the transverse bearings and passing to a circumferential channel 9 in the inner surface of the ring 10. Part of this air supplies the bearing for the casing 11, part is supplied to the lower bearing for the pendulum 26, and a further part passes through the channels 14, 17, to the upper bearing for the rotor 16, to radial passages 19 in the rotor for supplying tangential driving jets, to the lower bearing of the rotor 16, and through a passage 22 to the upper bearing for the pendulum 26.

Filed: 1954-05-12
Abstract: 761,910. Directive aerial systems. WADE, O. R. May 12, 1954, No. 13919/54. Class 40(7) [Also in Group XXIV] In a selective cam mechanism wherein a link 61 is reciprocated on rotation of a driving shaft 16, the shaft 16 is coupled to a cylindrical cam unit 14 having one or more differently-contoured continuous cam grooves around its periphery each engaged by a respective follower, and manual or power-operated selector means are provided whereby the link 61 may be releasably locked to a selected one of the followers to take up the particular movement thereof without interrupting the rotation of the driving shaft. As shown, the cylindrical cam unit 14 is rotatable in a frame 7 and has three cam grooves 18, 19, 20 disposed to give different throws. The grooves are engaged by three roller followers mounted on studs 29, 34, 39 carried by respective strip members slidable side by side in an opening in a housing 21. Surrounding the housing 21 is a sleeve 41 to which the link 61 is secured, said sleeve being formed with three notches 52, 53, 54 which are shaped as shown and co-operate with the three studs 29, 34, 39 so that the sleeve 41 may be selectively coupled to any one of the reciprocating studs by angular positioning of the housing 21, the later having for the purpose a hand lever 42 and ball detent 47. In the position shown, stud 39 is in the narrow portion of its notch 54 so that the sleeve 41 and link 61 are locked to the follower driven by the cam 20, while the 'studs 29 and 34'reciprocate idly in the wide portions of their respective notches. An additional notch 51 co-operates with a stud '24 on the housing 21 to hold the sleeve 41 in a rest position. The link 61 may oscillate a radar antenna through rack gearing, and in order to mtaintain the same central zero position in each of the three arcs of oscillation determined by the cams 18, 19, 20 the frame 7 is longitudinally slidable on its base 6 and is controlled by a compensating cam comprising a slotted arcuate segment 72 on the housing 21, said cam engaging a, roller on a stud fixed to the base 6 so that angular adjustment of the housing 21 to vary the throw of the link 61 also causes a longitudinal shift of the frame 7 compensating for the change in mid-position of the throw. The manual actuation of the housing 21 may be replaced by power-driven means operating in synchronism with the movement of other elements.
