Patent GB-752797-A (GB)
Title: Improvements relating to electric switching systems
Inventor: TIBBS CHRISTOPHER EVAN MUNDELL
IPC: H03F1/54
Filed: 1954-01-25
Abstract: 752,797. Protective arrangements; switching systems for transformers. RADIO HEATERS, Ltd. Jan. 25, 1955 [Jan. 25, 1954], No. 2191/54. Class 38 (4). Delayed action of a contactor 8 for shorting out surge-limiting resistors 9 in the primary circuit of a transformer 10, supplying hightension voltage to the oscillators of radio-frequency heating equipment, is obtained by arranging for the operating coil 12 of contactor 8 to be energized in parallel with a resistor having a large positive temperature coefficient (such as a tungsten filament lamp 20) over a common series resistor 15 when a main circuit-breaker 6 is closed, so that the low initial resistance of the lamp prevents immediate operation of the contactor. When the lamp resistance has increased sufficiently, the contactor responds and, in addition to short-circuiting the surge resistors 9, disconnects the lamp 20 and short-circuits resistor 15.

Abstract: 418,650. Positive clutches. SOC. ANON. A. SAURER, Arbon, Switzerland. Jan. 23, 1933, No. 2207. Void [Abridged as open to inspection under Sect. 91 of the Acts, July 24, 1933]. [Class 80 (ii).] The teeth 13 of a positive clutch member 9 are synchronized prior to engagement with teeth 15 on a member 4 by an auxiliary clutch ring 18 supported frictionally on or relatively to the member 9. Teeth 21 on the ring 18 protrude beyond the teeth 13 so that, on the member 9 being advanced towards engagement, the teeth 21 first engage the inner tips of the teeth 15. The ring 18 is pressed firmly against its frictional seating at 18<1> so that the teeth 13 are brought nearly to the speed of the teeth 21 which is the same as that of the teeth 15. Engagement of the main teeth 13 then follows without shock. An arrangement with plane frictional surfaces and an embodiment in change-speed gearing are described.

Title: Improvements in apparatus for making foundry moulds
IPC: B22C15/20
Filed: 1922-01-26
Abstract: 195,483. Jackman & Co., Ltd., J. W., and Sugden, J., (Administrator of Sugden, P. L.). Jan. 26, 1922. Moulding-machines.-Sand is compressed by a belt acting against the periphery of a drum and is delivered at high speed into the flask to pack the mould. The belt A, Fig. 1, runs over pulleys in a two-part casing, the lower part C' being pivoted at c<1> and adjustable at c<2> to vary the belt tension. The drum B has a groove in which the sand fed by a shoot or conveyer D<1> is compressed. The delivery run of the belt is substantially vertical. In a modification, the sand is compressed between the belt A and a second belt running over the drum and the casing C is mounted in trunnions to enable the angle of delivery to be controlled. The ramming head may be mounted in various ways; as illustrated in the Specification, (1) on a fixed arm over an adjustable table, (2) on a jointed radial arm carried by a fixed standard, and (3) on a carriage travelling on a runway suspended by a swivel from an overhead travelling carriage. In other modifications, the head mav be mounted on a truck or on a radial arm secured to a travelling wall bracket. Elevators may be fitted to supply sand from the floor level.

Title: Improvements in yarn winding apparatus
Inventor: SEVERINI GOFFREDO
IPC: B65H59/38
Filed: 1953-01-28
Abstract: 731,632. Winding yarn. SOC. R.L. STUDI E. BREVETTI APPLICAZIONI TESSILI. Jan. 28, 1953, No. 2390/53. Class 120(2). Apparatus for winding into conical packages yarn delivered at constant speed from a continuous spinning machine, comprises variable speed driving means for rotating the package at an average lineal take-up speed which is slightly greater than the deliveryspeed, a compensating and tensioning means for maintaining a substantially constant tension in the length or loop of yarn extending between the package and the delivery point, and means operable by variation in the length of the loop for controlling the variable speed driving means whereby the actual lineal take-up speed is intermittently decreased to a value less than the delivery speed. In one modification, Fig. 1, of the invention, the yarn 40 is delivered from the roller 10 to guide pulleys 46A, 46A<SP>1</SP> on a lever 47<SP>1</SP> pivoted at 481 and biased by a weight 50. As the lever moves to contact the points 52 or 53, of two parallel circuits energised from' a source 54, relays 55 or 56 are brought into operation to decrease or increase the take-up speed by varying the speed of the motor 59. Alternatively, the lever 47<SP>1</SP> may slide across a rheostat 571 to vary the excitation current in a circuit 58 to the motor 59 to change its speed. In a further form, a mechanical linkage connects a pivoted lever, similar to lever 47<SP>1</SP>, to a finger which causes the driving wheels 30, 31 to be separated against spring-pressure, to allow driving slip. This mechanical linkage may be replaced by an hydraulic connection or by electro-magnetic means. In a still further modification, as the driving pressure between the wheels 30, 31 is varied, a spindle brake is also actuated. In the embodiment of Fig. 7, the spindle is rotated through a shaft furnished with an electromagnetic brake 142. The yarn 40 passes about guides 143 on a lever 144 pivoted at 145 and biased by a weight 148. A resistance 146 and slide 145 vary the current to change the braking effect at 142 to adjust the take-up speed.

Abstract: 510,241. Glass manufacture; silica. GARBISCH, N. S. Jan. 28, 1938, No. 2771. Convention date, April 13, 1937. [Class 56] [Also in Group III] A process for purifying the waste sand which results from the grinding and polishing of plate glass comprises treating the waste, as it comes from the grinders, with dilute sulphuric acid, and then washing away the soluble iron compounds. Calcium sulphate, which is also present in the waste, is left in the purified material and serves to supply part of the calcium content when the purified material is used for making glass. The waste may be subjected, while in suspension in water, to preliminary treatment with a magnetic separator to remove particles of metallic iron, and it may also be digested with alkali, or with water in an autoclave, to decompose the particles of glass to form soluble sodium silicate. The purified sand may be calcined at 1400‹-1800‹F. to remove volatile or organic matter, and it may be sintered to form briquettes. or lumps which may be used for making glass or as bricks or building blocks.. The material may be used also as a source of silica in the manufacture of cement, as a cleaner or polisher, as a filler for pigments or plastics, and for other purposes, The Specification as open to inspection under Sect. 91 describes also the use of chlorination and of froth flotation for removing part of the iron in the waste. This subject-matter does not appear in the Specification as accepted.
