Title: Improvements in or relating to change-speed gearing
IPC: F16H61/02
Filed: 1933-01-26
Abstract: 418,505. Variable-speed gearing. BONN, C. R. H., 56, Gibson Street, Hillhead, Glasgow. Jan. 26, 1933, No. 2462. [Class 80 (ii).] Variable-speed epicyclic gearing comprises planetcarriers 9, 91, 9<2>, 9<3>, operable in the circuit of a pressure fluid, which is applied to the planetcarriers to move them axially for speed-changes. The planet-carriers are each formed as coned brake-discs 9 &c. held stationary by engagement with the conical casing 1, and there is a direct-drive coned clutch-disc 12, slidable, but not rotatable, on the brake-disc 9<3>, for engagement with a cone 9<4> secured to a driving shaft 2. The upper part of the casing 1 is divided into compartments 21, which, through ports 20-20<4>, supply pressure-fluid to one side of a selected clutch- or brake-disc and simultaneously connect its other side to exhaust, under the control of separate intergeared rotary distributing-valves 24, 25 for inlet and exhaust. The trains comprise sun-wheels 6, 6<1>, 6<2>, secured to the driving shaft 2, the combined planet-carriers and brake-discs 9 &c. also forming the annuli 11<1>-11<3> of succeeding trains. The driven shaft 3 carries the planetcarrier 13 of a reversing-gear comprising stepped planets 7, 17, and a sun-wheel 11, adapted to be held stationary for reverse, by means of the brake-disc 9. The pressure-fluid circuit comprises a gear pump 32, Fig. 5, actuated by the driving shaft, and drawing oil from a tank 31, formed on the gear-casing 1. The pressure-line 341 is connected, in all but the direct-drive position, with the small end of the casing 1, through ports 26<2> in the inlet valve 24, and a throttling-valve 38, the larger end of the casing being permanently connected through a throttling-valve 36 with the supply-tank 31 so that in the neutral position all the discs are moved out of action. In the direct-drive position the inlet-ports 26<2> are closed and pressure-fluid is supplied through the ports 20<4> and exhausted through the line 46<1>. The inlet and exhaust valves 24, 25 are arranged side-by-side in the top of the gear-casing 1 and are connected by pinions 27, Fig. 1, the valve 24 being turned by means of a handle 28, moving over an indicating- plate 30. There is a main pressure-relief-valve 33. The pump 32 is driven always in the same direction, irrespective of the direction of rotation of the driving-shaft 2, by means of forward and reverse gear-trains 58, 44, Fig. 2, constantly in mesh and driving through oppositely-acting one-way clutches 58<1>, 44<1>. The Provisional Specification states also that the brake-discs may operate in separate compartments and that reverse may be controlled by a separate valve.

Title: Improvements in bicycle frames made of light metal
IPC: B62K19/18
Filed: 1949-01-31
Abstract: 657,011. Making bicycles. OSKARSON, K. V. T. Jan. 31, 1949, No. 2548. [Classes 83 (ii) and 83 (iv)] Jointing by forging.-Light metal tubes 3 for bicycle frames are connected by pressing sleeves 1 of ductile metal into holes or slots 2 on the ends of the tubes which are supported by hard metal inserts 4 which may have recesses 6. Two or more symmetrically arranged jaws may be used for the pressing operation and the burrs formed may be ground off or the jaws may be arranged so that a bead of attractive appearance is formed. Aluminium alloys having a Brinell hardness of 90-140 such as that known under the Registered Trade Mark " Dural," or hydronalium or magnesium alloys having a Brinell hardness of 55-85 may be used for the tubing. Softer alloys of aluminium having a Brinell hardness of 50-90 such as that known under the Registered Trade Mark " Silumin," or a softer alloy of magnesium having a Brinell hardness of 40-55 may be used for the sleeves. The sleeves may be angular fittings which serve as supports for the saddle column, front fork or crank bearing.

Title: Toy fire arm with fire appearing at the muzzle
IPC: F41C3/00
Filed: 1934-01-25
Abstract: 414,584. Toy projectiles ; pyrotechnic compositions. ARNOLD, C., 47, Deutschherrnstrasse, Nuremberg, Germany. Jan. 25, 1934, No. 2642. [Classes 9 (i) and 9 (ii).] A bullet or rocket g having in its base a charge h of inflammable composition, such as a mixture of cerium and potassium chlorate, is used in a toy pistol having a percussion cap f fired by a hammer i. The flash from the percussion cap f ignites the charge h through a hole d, and this expels the bullet, after which a flash is visible at the muzzle of the pistol or at the tail of the bullet.

Title: Improvements in the manufacture of sheets of thermoplastic fibres for example glass fibres
IPC: D04H1/4209
Filed: 1966-01-20
Abstract: 1,134,683. Manufacture of glass fibres. COMPAGNIE DE SAINT GOBAIN. 20 Jan., 1966 [21 Jan., 1965], No. 2645/66. Heading C1M. In a method for the production of glass fibres, in which filaments of material are produced from rows of nozzles in a spinneret and entrained on a rotating drum which attenuates them, at the start of the operation, a drop at the leading end of a filament is caught by a moving belt and is moved such that the filament contacts the rotating drum and the drops are severed from said filament. A drop of molten glass 51 falls from a spinneret trailing a filament 50. The drop 51 falls between two rollers of a continuous moving belt formed of a plurality of rollers 63, and is trapped therebetween upon a stationary metal plate 64 situated beneath the upper run of the belt. The belt, which may be adjusted both in height and in inclination, is preferably inclined at between 30 and 60 degrees to the horizontal. Its speed is preferably that of the rotating drum 4. The trapped drop 51 is conveyed at speed such that the filament contacts the drum 4 and also contacts a knife 59. This severs the filament allowing the drop to be ejected. The filament is then entrained on the drum and drawn round it between two guides 5, 6. An air nozzle 9 placed between the two guides serves (a) to form a region of reduced pressure between guide 5 and drum 4 aiding in the entraining of the filament and (b) to form a region of high pressure between guide 6 and the drum 4 to hold the filament against the drum.
