Title: Improvements in or relating to rotary piston engines
IPC: F01C1/28
Filed: 1932-04-20
Abstract: 384,890. Rotary compressors. KRUPP GERMANIAWERFT AKT.-GES., F., Gaarden, Kiel, Germany. April 20, 1932, No. 11318. Convention date, April 24, 1931. [Class 110 (ii).] A rotary compressor comprises a " pear-shaped " piston 3 and a rotary abutment 5 which revolve at the same angular velocity in the same direction and compress fluid entering a port 6 and deliver the fluid through a port 7. The profile of the piston 3 is built up of two arcs of circles of radii a, b which are joined to a semicircle of radius d. The radii a, b, c are all equal to the distance vx between the centres of shafts 13, 14. The line of symmetry of the piston 3 lies at right-angles to a plane passing through points 25-19 on the abutment 5. Compression of the fluid in space 21 continues until the piston 3 is half-way between the points 15, 19 when the plate valves 17, 18 are opened and delivery begins. As the piston approaches the outlet 7 valve 17 is closed and the final delivery is through valve 18 alone. While the piston rotates between the points 19 and 15 all spaces are open to the inlet port 6. In a modified arrangement an arc of a circle displaces the point 4 and the arc of radius c on the abutment 5 is displaced by two arcs of the same radius c but with their centres shifted. The shape of the flank 12 may vary within the boundary of that shown in the Figure, for reducing the weight of the abutment or for other consideration. The flap valves 17, 18 may be replaced by other valves. The engine may operate as a prime mover, the direction of rotation of the rotors being clockwise. Further arrangements show two or three pistons co-operating with one abutment.

Title: Method and means for turning cigarettes and like shaped articles when packing same
IPC: B65B19/06
Filed: 1929-04-13
Abstract: 331,603. Gottschalk, P., and United Cigarette Machine Co., Akt.-Ges. April 13, 1929. Packeting cigarettes &c.-In feeding cigarettes to a packing-machine, those which are incorrectly placed are turned so that the imprints lie upwards. The cigarettes d are conveyed on links a of a conveying chain beneath a guide f, into contact with which they are raised by a spring g. If a cigarette is incorrectly placed, a finger i mounted on a spring h engages the longitudinal seam, and commences to turn it about its axis in an anti-clockwise direction. At the same time, an abutment b carried by the link a is drawn downwards by a fixed cam e, and a fixed stop k completes the turning movement into the position shown in Fig. 5, the abutment of b spring- ing up into the original position to hold the cigarette. The spring h, carrying the finger i, is connected to a stronger spring h' in such a manner that at first only the spring h acts, but later both act. The springs are pivoted at o and the action is controlled by stops s, i. In a modification illustrated in Figs. 6 and 7 of the drawings, the final part of the turning movement is effected by a blast of air, the nozzle of which may be opened by the action of the finger engaging the seam. An auxiliary blast of air may be directed at the lower surface of the cigarette. In the form shown in Fig. 12, a spring n is arranged to cause the cigarette to lie flat in the conveyer chain before the engagement of the seam by the finger i, and also completes the turning over as shown in Fig. 14. Separate springs may be arranged to achieve the same object. If any of the forms described, the feed band may be stationary and the turning device mounted for movement in relation thereto.

Abstract: 1,088,723. Semi-conductor strain gauges. ETHER ENGINEERING Ltd. March 15, 1965 [March 18, 1964], No. 11532/64. Heading H1K. [Also in Divisions Gl and H4] A peripherally damped diaphragm for use in pressure transducers or load cells is made 1À5-4 times thicker near its clamping points than at points removed therefrom. This removes the area of maximum stress from the immediate vicinity of the clamping points so that strain transducing elements may be more readily accommodated at points of high stress. Circular diaphragms are described with either one or both surfaces being non-planar to obtain the necessary thickness variation. A surface is generally concave and may be spherical, parabolic, hyperbolic, ellipsoidal, exponential, sinusoidal, or catenary shaped or may be partly planar and partly frusto-conical. The diaphragm may be of a semi-conductor material such as germanium or silicon so that strain gauges may be formed in the surfaces by diffusion.

Abstract: 743,328. Magnetic brakes. BRITISH THOMSON-HOUSTON CO., Ltd. April 28, 1953 [May 7, 1952], No. 11533/52. Drawings to Specification. Class 35. [Also in Group XXXVII] An electric brake providing stable low-speed operation of a hoist motor of the slip-ring induction type comprises a permanent magnetexcited rotor and a slotted stator with singlephase or polyphase windings connected to a variable resistor. The rotor of the brake may be of heteropolar salient pole form, in which case low frequency current is induced in the stator winding, or the rotor may have an imbricated construction, consisting of two sections coupled by a non-magnetic shaft with permanent magnets inserted between the sections. With the latter construction, higher frequency currents are induced in the stator winding of the brake. High-frequency stator currents may also be produced by using an inductor-alternator heteropolar arrangement in which the permanent magnets are inserted in the stator. Alternatively, a homopolar arrangement may be used. The control of rotor resistance of the induction motor and stator resistance of the brake may be effected simultaneously, so that reduction of the motor resistance leads to increase of the brake resistance.
