Title: Improvements in Differential Gears.
Inventor: LOGUE CHARLES HAYES
IPC: B60K17/16
Filed: 1917-11-26
Abstract: 123,783. Logue, C. H., and Ormsby, D. D. Nov. 26, 1917 Differential gearing.-In an epicyclic differential gear for motor-vehicles, the teeth of the bevel wheels and the planet pinions are helical and the spindles of the planet pinions run at each end in conical bearings which act as brake surfaces to retard the differential movement if one road wheel tends to slip on a greasy surface. The helical teeth of the pinions 8 introduce a wedging action thrusting the pinions radially outwards against the conical bearings 12 if a wheel slips during forward driving, or against the inner bearings 11 with reverse driving. The outer bearings 12 are adjustable and locking-means are provided for both bearings 11, 12.

Title: Improvements in or relating to water gauge glasses for boilers
IPC: F22B37/78
Filed: 1935-06-18
Abstract: 453,375. Gauge glasses. GRIMMETT, A. J., 65, West Bank Road, Birkenhead. June 18, 1935, No. 17464. [Class 123 (i)] To prevent false indications of a gauge 11 due to variations in temperature and density between the boiler water and the water in the gauge, water is allowed to flow continuously from the pipe 13 connecting the gauge to the boiler water space, through the bottom of the gauge and back to the boiler through a conduit 20. The flow of boiler water through the pipe 13 and the return to the boiler may be controlled by a thermostatically operated valve which reduces the flow of water as its temperature increases.
Patent GB-175627-A (GB)
Abstract: 175,627. Ragot, J. L. Gaget-. Feb. 17, 1921, [Convention date]. Force-transmitting mechanism.-The leverage of brake mechanism is varied automatically according to the load by a cam device actuated by the displacement of the vehicle body on the baring springs. The leverage is also increased during the application of the brakes. The brake levers 2, 3 are pivoted on pins 16 with guidemembers 7 which slide in relatively inclined slots a, a<1> in the levers and a connecting member 50. The pins 16 are disposed upon the ends of levers 4 pivoted at 15 to the member 50 and connected at their other ends to a member 5 engaging a pair of stepped cams 6. The shaft 9 of the cams has a lever 10 with a slot c engaged by a pin 56 on a lever 11 pivoted at 13 to a member 12 fixed to the member50. The lever 28, 30 pivoted at 29 to the vehicle frame is connected by rod 26 to the lever 11 and to a spring buffer or shock absorber 31, the plunger 35 of which is connected at 38 to an axle bearing 37 of the vehicle. The levers 2, 3 are held in the release position by a spring 43 and the member 50 against an abutment 46 by a spring 45. If the load is increased the cams 6 are partly rotated by the levers 10, 28 thereby displacing the pins 16 in the slots a, a<1> to increase the leverage. During this movement the levers 2, 3 are moved to reduce the clearance of the brake blocks by reason of the angle between the slots a, a<1> so that the stroke of the piston is not increased by the increased leverage. When the brakes are applied, the lever 3 is first turned about the pivot 16, and when the blocks actuated by the pull rod 52 have been applied to the wheels, the member 50 is moved to the left and causes a further movement of the lever 11, cams 6, and pivots 16, the brake blocks connected to the pull-rod 51 being applied at the same time by the movement of the lever 2. The buffer 31 serves to take up relative movement of the vehicle body and axle when the brakes are applied, movement of the cams 6 being impossible at this time. The leverage adjusting-mechanism can be rendered inoperative by disconnecting the rod 26 and inserting pins in holes b, b' in the levers 4 and member 50.

Filed: 1953-07-13
Abstract: 723,583. Modulating-apparatus. GENERAL ELECTRIC CO., Ltd., LEE, R. D., and PYLE, G. C. July 13, 1953 [July 11, 1952], No. 17626/52. Class 40 (5). Waves passing along a wave-guide 1 are modulated in amplitude by vibratory axial movement of a member 7 projecting through the guide wall 5, the movement being effected by an electromechanical device 12 fed from a signal source. The member 7, which may be of conducting or dielectric material, is slidable in a boss 6 integral with a disc 13, andthe boss is screwed into a block 4 attached to the guide wall 5, suitable gaps 10, 11 being provided to prevent leakage of wave energy. The member 7 is preferably a rod projecting through one of the broader walls 5 of a rectangular guide, at a point equidistant from the narrower walls. The electromechanical device 12 comprises a permanent or electro-magnet, in the field of which moves a coil fed by the modulating signal at terminals 16, and imparting an axial movement to the rod 7. The rod is screwed into a fibre disc 14, adjustment being effected by a screw-driver inserted through a hole 19 in the guide wall, and is locked by a seat 22. The disc 14 is secured to a light sleeve 15 upon which the modulating coil is wound. The casing 12 is held to the disc 13 by adjustable bolts 23 surrounded by compression springs. The vibratory movement imparted to the rod 7 by the moving coil varies the impedance presented by the rod and causes an amplitude modulation both of the transmitted and reflected wave energy, either of which may be passed to a utilization device.

Title: Improvements in or relating to the preparation of hydroxocobalamin
IPC: C07H23/00
Filed: 1961-05-15
Abstract: Hydroxocobalamin is obtained by reducing cyanocobalamin in the absence of a catalyst in an acid medium of pH of 1.5 to 2.0 by means of ferrous sulphate followed by oxidation in a medium of a pH equal to or greater than 8.  In an example ferrous chloride in dilute hydrochloric acid is added to aqueous cyanocobalamin to give a pH of 1.8.  The mixture is then heated to a temperature below 50 DEG C. while being concentrated in vacuo.  Soda is then added to bring the pH to 8.5 and the ferrous oxide precipitate recovered.  The filtrate is then oxidised by bubbling with air or oxygen, diluted with acetone and the hydroxocobalamin separated and purified by chromatography.

Abstract: 407,917. Reproducing music. SIEMENS & HALSKE AKT.-GES., Siemensstadt, Berlin. June 24, 1932, No. 17907. Void [Abridged as open to inspection under Sect. 91 of the Acts, June 25, 1932]. [Class 40 (iv).] In a system for successive reproduction from two or more optical records, the switching or fade-over arrangements are situated between the photo electric cells and a common first amplifier. In one arrangement, Fig. 1 (not shown) both cells are normally coupled to the amplifier but only one at a time is connected to the biassing source. Clicks are absorbed by a resistance-condenser circuit across each cell. In a modification, Fig. 2 (not shown) both cells are normally biassed and the coupling to the valve is through a potentiometer the mid point of which is connected to one of the battery terminals through a condenser to avoid clicks As shown in Fig. 3 both cells are normally biassed and abrupt switching is employed. The uncoupled cell is prevented from affecting the amplifier through the capacity of the switch contacts by the ground connection through a resistance 15 and condenser 14. Clicks are prevented by arranging that all the switch contacts, movable and fixed, are normally at the same potential.

Title: Improvements in or relating to magneto-strictive transmitter arrangements for echo sounding and sub-aqueous signalling
IPC: B06B1/08
Filed: 1939-06-20
Abstract: 579,121. Subaqueous sound transmitters. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., and ROUND, H. J. Juno 20, 1939, No. 17974. [Class 40 (iv)] For echo sounding or subaqueous signalling, a magnetostrictive oscillator R is connected to the hull k of a vessel by a rigid member RS, the area of its connection with the oscillator relative to the area of the oscillating surface of the oscillator being so proportioned as to introduce such damping as will enable the oscillator to take up a desired amount of energy from its energizing circuit. Longitudinal or transverse vibrations may be utilised, in each case the cross-sectional area of the connection being small compared with the area of the surface from which it receives vibrations. Alternative forms of the rigid connector comprise a hollow cylindrical member, Fig. 5 (not shown), utilising the lateral vibrations of a number of radially placed oscillators ; a hollow conical member, Fig. 4 (not shown), the oscillator being at the apex thereof ; and a transportable arrangement, Fig. 3 (not shown), in which the rigid connection terminates in a permanent magnet which serves to hold the oscillator to any part of the ship's hull. In another embodiment, the oscillator is mechanically unbalanced, the lack of balance being employed to assist in the transference of energy from the oscillator to the connector. In a further embodiment, longitudinal vibrations are utilized, but the connector is attached to a point intermediate the ends of the oscillator at a point dependent on the degree of damping required.
