Title: Improvements relating to controllers for electric circuits
IPC: H01H9/26
Filed: 1924-04-11
Abstract: 236,303. North, N. E., and Metropolitan-Vickers Electrical Co., Ltd. April 11, 1924. Controllers, interlocking, with auxiliary switches. - In a drum type master controller the main handle is interlocked with a reversing handle by axial movement of a notching ratchet, and actuates a " dead man's switch" in the normal turning movement, a single spring controlling the notching action and the " dead man's switch." When the driver depresses thehinged main handle 2, the notching ratchet 24 slides down along the spindle compressing a spring 25, and freeing an interlock with a reversing ratchet 3. The reversing handle 3 can then be moved out of the neutral position shown so as to set the reversing switch 10 for forward or backward running, after which the main handle is turned through the successive positions determined by the engagement of the notches of the ratchet 24 with a rollerended arm 31 pressed by a spring 37. Movement out of the first and deepest notch turns a spindle 13 far enough to close the " dead man's switch " 15, 16, which remains closed during subsequent steps. If the handle is released, the spring 25 lifts the ratchet 24 out of engagement, the switch 15, 16 is opened by the spring 37, and the roller 31 blocks the ratchet 24 against downward movement until the handle has been brought back to the starting point. The reversing handle 3 is removable from the head 45 when in the neutral position, and is locked against removal by a pin 48 when in any other position. An air brake may be applied by causing the upward movement of the ratchet 24 to act on the end of a valve-rod 49.

Abstract: 609,961. Adjusting radio apparatus. MARCONI INSTRUMENTS, Ltd., GARTHWAITE, E., and CARMAN, G. T. M. March 26, 1946, No. 9370. [Class 40 (v)] An adjustment device for a number of sets of elements mounted on a rotatable carrier, each of which is brought into use at one of a number of predetermined positions of the carrier, comprises a shaft which drives the sets of elements through their ranges of adjustment and intermittently operates a device for overcoming a detent holding the carrier in one of its predetermined positions and moving it to its next position, so that by continuous rotation of the shaft in one direction, each set of elements is brought into use in turn, and adjusted through its range. A number of tuned circuits only one of which is shown, comprising an inductor 6 and variable condenser 7 are mounted between two co-axial discs 3, 4. One or both of the discs has a notch (not shown) corresponding to each tuned circuit, and engaging a spring catch 8, which holds the carrier so that the stator of one of the variable condensers 7 co-operates with pick-up plates 9. The operating shaft 11 drives the shaft 14 of condenser 7 through gear-wheels 12, 13, and also drives a toothed sector 19, co-operating with a fixed gear-wheel 20, through gear train 15, 16, 17. Toothed sector 19 and gear-wheel 20 form an intermittent epicyclic drive for the carrier 3, 4, overcoming the spring detent 8 and rotating the carrier to bring the next tuned circuit into use. Continuous rotation of the shaft 11 thus adjusts each variable condenser 7 in turn through its range.

Title: Improvements in or relating to conveyors for granular goods, particularly for grain
IPC: B65G27/00
Filed: 1949-04-06
Abstract: 668,179. Sieves; mixing appliances. OTT, W. April 6, 1949, No. 9409/49. Classes 86 and 117 [Also in Group XXX] A reciprocating conveyer which may be used as a sieve or as a mixing device in addition to a conveyer for granul a r material consists of an inclined conveying surface formed with steps and reciprocated so as to elevate the material from step to step, the steps being in the form of pockets of such form that the conveying surface of one pocket extends beyond the rearmost end of the next higher pocket, as measured in the general conveying direction, to form a lip. The pockets c, each having a lip x, are made of wire mesh so as to sieve the material and are enclosed in a casing b having a cover plate d. The casing is oscillated in an arcuate path in the general direction of the slope of the steps by means of an eccentric t and pivoted links n. o, which suspend the conveyer from fixed side walls or beams. Alternatively, the oscillations may be in a straight line. Material to be sieved and/or mixed, enters a hopper a at the foot of the conveyer and is repeatedly thrown against the cover plate which deflects it into the next higher pocket. At the top the material falls into a shoot p. The cover plate d may be curved in relation to each pocket to increases the deflection of the material. Dust passing through the wire mesh during conveying runs down a surface h to the foot of the conveyer. For mixing solids with liquids (or solids), e.g. for wet-immunizing grain, the immunizing or other liquid (or solid) may be led into the casing b through a pipe.

Title: Improvements in or relating to the manufacture of a binding agent for core sand
IPC: B22C1/26
Filed: 1944-05-18
Abstract: 573,171. Mould and core materials. OEL- & CHEMIE-WERK AKT.-GES. May 18, 1944, No. 9621. Convention date, May 1, 1943. [Class 83 (i)] In making a binding-agent for core sand from sulphite lye, a substance having an acid reaction is added, preferably to the concentrated lye. The mixture may be heated under reduced or increased pressure to increase the viscosity and remove some of the free sulphur-di-oxide. Corrosion inhibitors, e.g. quaternary ammonium compounds, alkaloids, products of condensation of amines with aldehydes, basic petroleum and tar fractions, tannic, mercaptans, urea, thiourea and their derivatives, glue, starch, yeast, molasses, &c. may be added finally. The first addition may be an acid, acid salt, or a substance which produces acid on heating, e.g. organic sulphonic acids or esters, salts of polyvalent metals, or ammonium salts. The sulphur-di-oxide removal may be assisted by blowing air through the mixture, by stirring or by increasing the surface exposed. 100 parts of lye containing about 50 per cent of water may be mixed with 20 parts by weight of 50 per cent sulphuric acid solution and heated to 70‹ C. while blowing or stirring, until the viscosity increases considerably. After cooling, one part of hexamethylene tetramine is added. If solid pulverized lye is used, 100 parts may be mixed with 20 per cent of ammonium sulphate and the mixture used with moist sand or with various proportions of water and sand, with or without other binding agents. Cores should be made with 5 to 6 per cent of the binder and dried for about an hour at 220‹ C., but, unless this temperature is required to generate the required acid, a longer time at a lower temperature may be used.
