Title: Improvements relating to commutators for electrical machines
IPC: H01R43/06
Filed: 1962-03-21
Abstract: 944,536. Making commutators; soldering. ROBERT BOSCH G.m.b.H. March 21, 1962 [April 28, 1961], No. 10756/62. Headings B3A and B3R. [Also in Division H2] A method of making a commutator having U-shaped connecting lugs at one end of its segments comprises lifting a portion of the segments by paring, fitting the web of the U-shaped connecting lug within the resultant recess, and fixing it therein by means of said pared portion. In order to facilitate the paring operation two grooves 16, 17, Fig. 3, may be cut in each segment; these grooves may also be used to assist in the location of the connecting lugs, which in this case have projections extending downwards of the web from the lugs (Figs. 5 and 6, not shown). The connecting lug may also be soldered to the commutator segment during a dip soldering operation which is carried out to join the armature windings to the connecting lugs, or the lugs may be soldered to the commutator segments prior to assembling the armature. Bridging of the commutator segments during the dip soldering is prevented by forming the insulating layers separating the segments such that they project slightly above the outer diameter of the segments. The invention is particularly suited to the assembly of commutators for machines utilizing high currents, such as I.C. engine starter motors.

Title: Improved suspension means for the superstructures of motor vehicles
IPC: B60G21/02
Filed: 1938-04-08
Abstract: 498,978. Vehicle suspensions. KOLBE, J. April 8, 1938, No. 10770. Convention date, Aug. 12, 1937. [Class 108 (ii)] In a suspension for a motor-vehicle superstructure of the kind in which the supporting elements on the axle comprise inclined links or guide members adapted automatically to tilt the body inwardly on a curve, the links or guiding elements of the front and rear axles are positively coupled so that their movements take place in the same direction. In the arrangement shown in Fig. 1, the superstructure 1 is supported on the front and rear axles 4, 7 respectively by means of inclined pairs of links 2, 3 and 5, 6, which are associated with a common longitudinal rotary tube 8 through the medium of levers 9, 10 and links 11, 12. In a modification, Fig. 5, the links 2, 5 are provided with arms 22, 23 which co-operate with pistons 24, 25 in the cylinders 20, 21 of an enclosed fluid system, while in a further construction the links 2, 5 are inter-connected by wires passing around pulleys and attached to bellcrank levers. With such constructions the movements of the links are necessarily also equal, so that the axles remain parallel. If, however, the vehicle is intended for less smooth roads, an initially stressed spring or equivalent device may be interposed between the links 2, 5 and the common mechanical or fluid connection, such device tending to constrain the axles to move in the same direction, but yielding to permit a certain differential movement. Thus, as shown in Fig. 9, between the link 11 and the common connecting tube 50 are arranged a pair of pivotally connected bifurcated elements 40, 41 and a stressed spring 43, which tends to constrain the elements 40, 41 to move as a rigid unit but which yields on excessive stress resulting, for example, from the axles assuming a non-parallel position on a rough road. In other modifications the yielding elements may consist of torsion tubes or of springs associated with a fluid system.

Patent GB-659650-A (GB)
Title: Improvements in the manufacture of hollow rubber balls
IPC: B29C65/02
Filed: 1949-04-26
Abstract: 659,650. Molding hollow rubber balls. SWIFT TENNIS BALL CO. PROPRIETARY, Ltd. April 26, 1949, No. 11080. Convention date, May 4, 1948. [Class 87 (ii)] A method of moulding a hollow rubber ball from natural indiarubber, synthetic rubber, or rubber substitute material, comprises shaping integrally with one another a major ball part 11, Fig. 3, and a minor ball part, the part 11 being formed as a hollow spherical segment and the minor part being formed as a plurality of petals 13, 14, 15, 16, integrally connected to the segment around the opening thereof and arranged so that they may be united to close the opening of the part 11 to form a hollow spherical rubber ball. The petals have bases which lie in a common plane where the converging edges 17, 18 of adjacent petals meet. Between the edges of adjacent petals are V-shaped notches or slits 22 which are prevented from extending by a bead 24 formed upon the outside of the ball, which bead reinforces the petals and forms a fold line for them. Apparatus for moulding the major and minor parts, comprises a core, Figs. 5, 10, and mould halves 41, 42. The core has a stem 32 upon which is formed a pearshaped extension composed of a truly spherical solid portion 33 combined with a frusto-conical portion 34. An annular bead 33a is formed around the lower boundary of the part 34, which part 33a produces the bead 24 on the ball part 11. Four tenons, 35, 36, 37 and 38, having outer convex surfaces, Fig. 10, are formed on the part 34, and the petals are moulded in the V-shaped recesses formed between the tenons. In operating the method a quantity of mouldable rubber material 40a is placed in the lower mould half 42, Fig. 5, prior to closing the mould on the core, and heat is then applied to the core by means of steam or electrical elements. After this stage the mould is broken, and the core removed by expanding the formed hollow rubber shell 11, Fig. 10. The shell is then placed in a single or multiple curing mould, the petals are pressed down to complete the spherical shape, and the mould is subjected to heat to complete the curing. Internal pressure may be applied either by a gas generated from pills introduced before sealing the ball or by compressed air. The petal edges 17, 18, come together as a butt joint when they are pressed down, but a mitred or overlapping joint may be used instead. The joints so formed are sealed with a suitable cement before the ball is cured. In the curing operation the annular bead 24 is obliterated. In the Provisional Specification the V-shaped slits between the petals are prevented from extending by small nipples formed on the inner surface of the ball at the extremity of each slit, or each slit may be terminated by a circular aperture afterwards filled with cement.

Filed: 1939-04-12
Abstract: 530,568. Cathode-ray tubes. ARDENNE, M. VON. April 12, 1939, No. 11134. Convention date, April 13, 1938. [Class 39 (i)] [Also in Group XX] In an ultra-violet microscope the whole path of the U.V. rays-except in the immediate neighbourhood of the object-is through spaces substantially free from atmospheric air; the space may contain hydrogen. The rays-of less than 2000 A.U.-are formed in a discharge tube A with a filling of xenon or krypton in combination with argon and neon, and a fluorspar window B; they pass through a Christiansen filter C- consisting of fluorspar narticles in a liquid having the same refractive index as the fluorspar-to a lens E, which closes an orifice in an exhausted chamber F and through a second lens I on to the object K. The position of the object is adjustable for focusing purposes; the object is in an immersion liquid such as hexane which does not absorb the desired wave length and with the fluorspar filter and lens passes substantially monochromatic light. The object support is of fluorspar. The rays then enter a second evacuated space H through the lens M on to an eye piece N, which for focusing directs the image on to the photo cathode P of an image transformer; the emission therefrom is focused and accelerated on to a screen S by electrodes T, R, a window V permitting observation of the screen S. The electron optical arrangement is used only to focus the object, the electron apparatus being slidable with a photographic plate holder O; the plates, which take up the position of the photo-cathode, must be sensitive to U.V. rays. Alternatively the photographic plate may take up the position of the screen S when ordinary plates can be used; or the cathode may act also as a mirror to reflect part of the U.V. rays on to a photographic plate while the other part is used to energize the screen S the electrons being deflected electromagnetically. The envelope containing the electron device and the photographic plates is connected to the space F by a channel G. The photo cathode may be translucent in which case the image produced thereon mav be directly observed and photographed. The cathode may be a layer of platinum or aluminium deposited by evaporation.

Title: Improvements relating to the electrical control of hydraulic power means
IPC: B66B1/04
Filed: 1938-04-12
Abstract: 513,542. Hydraulic machines. ALDOUS & CAMPBELL, Ltd., and HALLIDAY, J. W. April 12, 1938, No. 11214. [Class 69 (ii)] [Also in Group XXX] Hydraulic apparatus is brought to rest gradually and exactly at a selected point, for example a hydraulic lift is stopped at a selected floor, by mechanism operated automatically by the cage or moving body as it approaches the stopping place to cause restricted delivery of the operating fluid to, or exit from, the ram cylinder. In the illustrated form showing the application to a hydraulic lift, the main delivery and exhaust valves are cut out on approaching a floor at which it is desired to stop, and a small auxiliary valve automatically brought into operation. Fig. 1 shows in plan a main control valve having a port 4 leading to the ram (not shown) and communicating alternatively with an inlet port 2 from the pressure main and an exhaust port 3. Depression of an appropriate button on the cage or at a floor energises the motor 14 and the solenoid 23. The motor drives worm gear 15 and epicyclic gear 13, while the solenoid applies brake blocks to fix the outer ring of the gear so that the drive becomes effective to move the crank 6 through 90 degrees in one direction or the other until stopped by a limit switch 17, and thus through the connecting rod 5 slides the valve into one or other of its extreme positions, in which the ram is connected to the main or to exhaust. The pressing of a floor-selector switch causes ramps in the well to operate a switch as the car approaches the selected landing and so close the main valve and open one of the auxiliary valves to enable the cage to creep up or down to the landing. The circuit thus established energises one or other of the solenoids 29, 30, Fig. 5, and raises the armature 43 to tilt the bar 40 about the remote pivot 39. This opens one of the needle valves 35 and also compresses the restoring spring 50. At exact floor level another ramp in the wall opens the circuit and all valves are closed. Should the cage creep away from the landing one or other of the needle valves are opened automatically, and restoration takes place. The two needle valves are connected by pipes 55, 57, Fig. 1, to the corresponding pipes of the main valve. Should the current fail, the main valve can be controlled immediately from a hand rope on the wheel 11 which is connected to the crank 6 by chain gear 8, 9. This latter drive is isolated from the motor 14 by reason of the de-energising of solenoid 23 rendering the epicyclic gearing 13 non-effective.
