Abstract: 655,221. Endless belt conveyers. EGGLETON, O. J. Sept. 23, 1949, No. 24882/48. [Class 78 (i)] [Also in Group VIII] Clothes are passed through a laundry washing machine (see Group VIII) by means of an intermittently travelling conveyer 11 to which a reciprocating up and down movement may also be applied by means of eccentrics 34 on spindles 35, and a plate 32 mounted underneath the conveyer. The cloths are fed at the point F on to the conveyer 11 which may be of perforated rubber and is mounted on rollers 12, 13, 14 and 15. Rollers 40 are pressed down on to the conveyer 11 by springs 41. The intermittent motion is imparted to the conveyer by mechanism (Fig. 2) comprising an arm 42 pivoted at one end and pressed by a spring 43 against an eccentric 35a mounted on one spindle 35. A chain 44 attached to the arm 42 passes around sprockets 45, 46 and is tensioned by a spring 47. The sprocket 46 is fitted with freewheel mechanism so that the drive is effective in one direction only, the drive being through a sprocket 54, chain 56 and sprocket 55. Sprocket 55 is mounted on the spindle of roller 13 which is geared to rotate with another roller 16, the conveyer passing between and being driven by the rollers 13, 16.

Transformers. - For operating load-indicating instruments or protective relays associated with a transformer, the latter is provided with a tertiary winding so arranged and located with respect to the main windings that it is affected only by the leakage flux or a part thereof. Figs. 1 and 2 show a shell-type transformer in which the primary 11 and secondary 12 embracing the centre leg of the core 10 are concentrically spaced, the tertiary winding 13, connected to an instrument 15, being in the form of a loop disposed between the main windings so as to embrace part of the leakage flux while being non-inductive as regards the main flux. Fig. 3 shows an alternative arrangement in which the sides of the loop forming the tertiary winding 13 lie respectively inside and outside the secondary winding 12.

Abstract: 259,616. Verein fur Chemische Industrie Akt.-Ges., (Assignees of K³chler, E.). Oct. 12, 1925, [Convention date]. Void [Published under Sect. 91 of the Acts]. Charcoal.-Carbon is activated or spent activated carbon is re-activated by treating it at elevated temperature with a stream of dry or moist gas containing free oxygen, such as air whereby partial oxidation occurs. The gas may be supplied under pressure or by means of suction, intermittently or continuously. Preferably the carbon to be treated is in granular form and the treatment is carried out in tubes having permeable walls which may be made of iron besides clay and fire-clay, whereby the products of combustion are readily removed and coking thus prevented. The speed of the stream of gas, the time of treatment, the thickness of the layer of carbon and the size of its granules may be varied. In one example, carbon is activated in an iron tube by means of a gas containing oxygen and in a second example spent carbon originally prepared by means of zinc chloride is reactivated.

Title: Improvements in or relating to the production of trifluoroacetic acid and derivatives thereof
IPC: C07C51/58
Filed: 1945-10-01
Abstract: Salts of trifluoroacetic acid are prepared by reacting acetone with elemental fluorine in the vapour phase at elevated temperatures, preferably 200-250 DEG  C., in a reaction vessel containing a fluorination catalyst comprising gold and/or silver and subsequently reacting the trifluoroacetyl fluoride obtained in the gaseous reaction product with an aqueous solution of an alkali metal or alkaline earth metal hydroxide.  Catalysts mentioned are copper turnings or gauge coated with silver or gold.  Nitrogen may be present as a diluent, the reactants being separately preheated to about 200 DEG  C. and conditions arranged so that some unreacted fluorine remains in the gaseous products as, for instance, by using 10 to 12 mols. of fluorine for each mol. of acetone.  Before hydroxide treatment, hydrogen fluoride, acetone and fluoroacetone may be removed from the gaseous products, the preferred hydroxide being that of sodium.  The trifluoroacetic acid salt may be converted into the free acid or its alkyl esters or amide by conventional methods. In an example, mixed acetone and nitrogen heated to 200 DEG  C. is passed into the top of an iron reactor packed with gold-plated copper turnings and contacted with mixed fluorine and nitrogen also preheated to 200 DEG  C. and passed in at the top of the reactor so that the exit gases contain a small excess of fluorine, reaction is maintained at 215 DEG  C. and after removal of high-boiling products, hydrogen fluoride, acetone and fluoroacetone, the trifluoroacetic acid formed is absorbed in caustic soda solution and sodium trifluoroacetate extracted therefrom with hot ethyl alcohol after neutralization with aqueous hydrochloric acid.

[Class 39 (i)] [Also in Group XXXVII] In a combination of a tubular gasfilled electric discharge device having at least one thermionic electrode heated independently of the discharge and means for operating the device from a supply of not greater than 100 cycles, the device has a surrounding electrode connected to earth either through a finite impedance or a low impedance path which is adapted to be interrupted when the discharge is to be started. A " surrounding " electrode is defined as one which touches or approaches very nearly to the envelope over most of its length between the electrodes and which covers a considerable part of the circumference of the envelope in planes normal to the said length. It may consist in a mesh or helix or in a continuous strip covering, for example, one-fifth of the envelope circumference.

The electrodes are heated independently of the discharge and are connected to 50 cycle A.C. mains giving 150 volts through an impedance of 250 ohms. Regular shunting is secured by connecting the strip to earth through a resistance of 1 to 3 megohms, a 0.001-0.01ÁF condenser or an interrupter. An interrupter comprising two thin metal strips mounted face to face on an insulating block with a small sliver of mica separating them at one point is mentioned.

In one embodiment, Fig. 2, a load 1 is supported by a gantry 7 spaced from a supporting surface 2. A polythene bag having closed ends and provided with a filling aperture 4 and a venting aperture and valve 5 is located between the load 1 and the surface 2, and there is injected into the bag a chemical mixture capable of forming a polyurethane foam. The foam forms with the production of gas/vapour which inflates the bag and causes it to engage the underside of the load, and following inflation of the bag the gas/ vapour is expressed through the venting aperture and valve 5 until the foam fills the bag. Following solid setting of the foam the load is released to rest on the plinth. The polythene bag is sufficiently flexible to accommodate any irregularities on the supporting surface 2, and the foam is able to deform sufficiently to form upward protrusions 12. While it is preferred that the foam mix is injected into a single empty bag positioned between the load 1 and the supporting surface 2, in some instances it may be possible to form a plinth using a plurality of bags which after the foam mix is injected into them are immediately sealed and slipped into position between the load and the supporting surface.
