Title: Improvements relating to soluble mercury compounds
IPC: C07F3/12
Filed: 1921-04-15
Abstract: Water-soluble derivatives of salicylic acid containing nuclear mercury are obtained by treating hydroxy-mercuric-salicylic acid anhydride or the like with a soluble cyanide at moderate temperatures and separating by fractional crystallization the resulting o- and p-compounds of the formula NC.Hg.C6H3OH.COOR where R may be potassium.  The reaction may be effected with cooling and in the presence of such quantity of water that both salts are separated, the liquid being iced before filtering.  The product may be washed on the filter successively with ice water, 50 per cent alcohol, and concentrated alcohol, and lixiviated with three times its weight of water at 25 DEG  C., to extract the more soluble p-compound, the residual o-compound. being then recrystallized from hot water. Alternatively, the reaction may be effected in the presence of more water at ordinary temperatures; after heating, the p-compound is found in the solution and the o-compound remains undissolved. By adding acids to the aqueous solutions of the potassium salts, the free acids may be precipitated.  The silver salts may be prepared by adding silver nitrate.  The potassium salts are suitable for therapeutic use.ALSO:Silver carboxylates of the formula NC.Hg.C6H3OH.COOAg are got by adding silver nitrate to solutions of the corresponding potassium salts, which may be prepared by the action of potassium cyanide on hydroxy-mercuric-salicylic acid anhydride, the o and p-salts produced being separated by fractional crystallization.

Title: Improvements in or relating to the cleaning of small stone and other hard discrete material
Inventor: KNIBBS NORMAN VICTOR SYDNEY
IPC: B07B7/08
Filed: 1959-04-01
Abstract: 896,829. Pneumatic separators. FAWKHAM DEVELOPMENTS Ltd. April 1, 1959, No. 11085/59. Class 117 Small stone is separated from foreign matter such as clay, soil or dust adhered to it by directing cleaning air or gas transversely at high velocity into a cleaning zone containing the stone to impart violent motion to it whereby the adherent matter is detached from the stone, further air or gas being passed upwardly through the zone to combine with the cleaning air or gas to carry away the foreign matter. As shown, stone to be cleaned is fed into cleaning apparatus through a tube 27 and falls into trunks 14, defining cleaning zones, and hoppers 15. High velocity air enters a chamber 11 at 22 and enters the trunks 14 through nozzles 24. Further air enters a chamber 19 at 23 and reaches the trunks 14 through small holes 21. The air causes the material above the level of the nozzles 24 to form a fluidized bed. The high velocity air from the nozzles 24 causes the particles in the lower part of the bed to collide with one another thereby detaching adherent foreign matter. The combined air from the nozzles 24 and holes 21 carries the foreign matter upwardly and away through outlet duct 26. The cleaned stone is removed through discharge tubes 16 by a sweeping arm 29. The air introduced through the nozzles 24 may be hot to provide a drying action and the air passing through the holes 21 may be cold to cool the cleaned stone.

Title: Improvements in the electrical reproduction of sound
IPC: G11B9/00
Filed: 1930-04-08
Abstract: 354,341. Sound-reproducing machines ; gramophone records. LOW, A. M., 1, Woodstock Road, Bedford Park, London. April 8, 1930, No. 11090. [Class 40 (ii).] Relates to apparatus for electrically reproducing sound from a grooved record, by varying the capacity of a condenser in accordance with the recorded sound. According to the invention, in order to reproduce sound from a record of the type having a lateral-cut groove, the condenser is constituted by a conducting surface of the record itself and a small plate, which plate is traversed across the record in such a manner that variations of capacity are caused by the varying displacements of the groove beneath the plate. The device shown in Fig. 2 comprises a small insulated condenser plate c, which has a diameter approximately equal to the width of the record groove, the plate being mounted on a support d on a carrier arm d<1>. A needle holder d<2> is pivoted on the member d and is also connected thereto through vibration absorbing arms f<1>, so that when the needle tracks in the record groove x, Fig. 1, the plate c is traversed across the record without being vibrated by the action of the groove on the needle. The face of the record is metallized, and the plate c together with the record face thus constitute the electrodes of a condenser, which are separately connected to an amplifier. As the plate traverses the record, with the groove moving beneath it, the lateral displacements of the groove cause variations in capacity, whereby the recorded sound is reproduced. A modification is described wherein the condenser plate is guided radially across the record by a screw feed mechanism. In another construction, the record has a special guide groove on a central zone, this groove being engaged by a needle mounted on an arm extending from the pivoted arm which carries the condenser plate.

Abstract: 416,947. Automatic-feed weighers; endless-chain elevators. THOMAS, W. J., and THOMAS, C. W., 30, Hythe Road, Willesden, and BOVEY, D. J., Brentor, Southern Road, East Finchley, both in London. April 22, 1933, No. 11822. [Class 143.] In an automatic weighing machine for loose material in lump form such as lump sugar, the scale pan after receiving the main portion of its charge receives in succession, until the weight is made up, single lumps of sugar abstracted from a receptacle by a supplementary feeding device moving in a vertical plane below the receptacle, after which the operation of the supplementary feeding device is suspended until the scale pan has been emptied and re-set for the next weighing operation. The scale pan 1 receives the main portion of its charge from an auxiliary scale pan (not shown) operating automatically in known manner, and the weight is made up as described below by the supplementary feeding device. The lump sugar descending a shoot 29 accumulates in the receptacle 8 which is pivoted in bearings 20 and is vibrated by a notched wheel 21. An endless bucket conveyer 4 driven by an electromagnetically-controlled clutch of the kind described in Specification 5152/10, [Class 80 (ii)], picks up the sugar, one lump in each bucket 7, and deposits the lumps successively into the scale pan until, at the correct weight, an electric contact on the scale beam opens and the clutch stops the movement of the conveyer 4. The feeding device then remains at rest until the scale pan has discharged and resumed its normal position. The conveyer comprises a number of bent metal plates 14 hinged together and provided with upstanding V-shaped buckets to accommodate single pieces of sugar. The upper supporting (and driving) roller of the conveyer is provided with radial pins 16 which enter and project through central holes in the plates 14 and ensure the ejectment of the lumps of sugar into the scale pan. The upper strand of the conveyer enters the receptacle 8 through a tubular extension 17 and passes along a channel-shaped support arranged in a slot at the bottom of the receptacle. The upper portion of the slotted bottom of the receptacle is bent in a downward direction and spaced away from the channel support by a wedge 18 so that excess lumps of sugar may fall back into the receptacle.
