Title: Process for drying substances in the condition of sludge, and for evaporating solutions
IPC: F26B1/00
Filed: 1936-07-14
Abstract: <PICT:0472437/III/1> A process of drying thinly - fluid sludgy materials or of evaporating aqueous solutions of solid substances consists in applying the sludge or solution to a granular carrier of the same or similar composition as the desired finished product or of such a character as not to impair the dried product, a resulting granular mass being formed which is no longer fluid and is permeable to gases, and said mass is spread in a thin layer on a permeable support and dried by gaseous drying medium drawn through the support. Instead of mixing the material to be dried and the carrier material before transfer to the drying chamber the carrier may be disposed on the permeable support, and the material to be dried be spread over the carrier, mixing preferably taking place by the aid of a shaker or like device.  In the arrangement shown, finegrained carrier substance is contained in a hopper 1 and sludge or mother liquor is contained in a vessel 2.  The substances are supplied to a mixer 3 from which they pass through a hopper 5 on to an endless permeable conveyer 6 where they are dried by exhaust gases or air drawn through the material by a fan 9.  The dried product collects in a vessel 10 and is passed to a mechanical screen 11.  One grade of material is removed as a finished product, and another grade is returned to the hopper 1 to serve as carrier substance for further wet material.  The drying process may be carried out in two or more stages, for example sludge which has been spread over the carrier substance may be pre-dried on a first grate or permeable support, being then transferred to a second grate where it is completely dried by a hot drying gas.  The exhaust gas from the second apparatus may be used for the pre-drying in the first apparatus.  Also fresh quantities of sludge may be added to the pre-dried material in the second apparatus.  In a further arrangement, the finishing drier receives only a portion of material from the pre-drier, the remaining portion being mixed with return material from the finishing drier and with fresh sludge before being again passed through the pre-drier.

Abstract: 1435991 Machinery guards WOLF MACHINE CO 25 April 1973 [20 Sept 1972] 19769/73 Heading F2J A guard assembly 32 for the motor-driven rotary knife blade 11 of a portable cloth-cutting machine comprises a fixed rear section 33 on which is pivotally mounted a front section 38, the rear and front sections 33, 38 completely covering the exposed rear and front peripheral segments respectively of the blade 11. An adjustable trigger mechanism 58 adjacent the operator's handle grip 22 is connected via a link 59 to the front guard section 38 whereby the operator may turn, i.e. open and retract the front guard 38 (Fig. 3) to expose the blade 11 sufficiently to cut a cloth stack 15 of multiple fabric layers, the guard 38 being spring and weight biased to automatically return to a closed position, i.e. failsafe, when the machine is removed from the cloth stack 15. A blade sharpener device 26 pivotally mounted at 29 on the machine centre standard 19 is positioned such that the sharpener device 26 can only be engaged to sharpen the blade 11 through a cutaway portion 46 in the front guard 38 (Fig. 4) when the front guard 38 is in its fully closed position, an auxiliary guard 37 on the sharpener device 26 serving to cover the cut-away portion 46 (Fig. 2). The front guard 38 includes a pointer 48 aligned with the cutting blade 11 such that the operator can readily follow a traced pattern on the top of the cloth stack 15. The rear guard 33, pivotally carrying the front guard 38, is readily removable, as a unit, at (34) (Fig. 1, not shown) to facilitate changing of the circular blade 11 when required.

Patent GB-621117-A (GB)
Title: Improvements in or relating to alkylene cyanohydrins
Filed: 1945-08-03
Abstract: Alkylene cyanohydrins are prepared by heating an equimolecular mixture of an alkylene oxide and hydrogen cyanide in liquid phase under pressure in a closed vessel to an activation temperature at which an exothermic reaction begins and maintaining a predetermined upper limit to the temperature during the reaction by carrying out the reaction in the presence of a polar solvent so as to reduce the reaction velocity and, if necessary, also by cooling the reaction zone.  In the case of ethylene oxide, the activation temperature is generally between 90 DEG  and 150 DEG  C. Suitable polar solvents are water, alkylene cyanohydrins and the liquid reaction product of a previous run.  The activation temperature is lowered when there is present as catalyst a substance exerting an alkaline effect and/or permitting the formation of CN- ions such as pyridine, and other amines, hydrogen cyanide polymer, ammonia, alkali-forming metal oxides and hydroxides, while reaction in glass or iron has a similar effect. The concentration of the reactants in the solvent is generally between 15 and 50 per cent.  The uncontrolled exothermic reaction is indicated to be explosive.  A preferred process comprises feeding alkylene oxide and hydrogen cyanide into a closed vessel together with a portion of the liquid product of a previous run and/or other polar solvent and, if desired, one of the above catalysts; the vessel is then heated to the activation temperature with subsequent cooling, if necessary.  A portion of the product is thereafter recycled with or without more solvent or catalyst, while the major portion is withdrawn to a separation still for recovery of the formed cyanohydrins.  Experiments are described illustrating the preparation of cyanohydrins by reaction of hydrogen cyanide with ethylene oxide and propylene oxide in steel or glass bombs using water, ethylene cyanohydrin or the liquid product of a previous run as the polar solvent, in the presence or absence of calcium oxide or hydrogen cyanide polymer as catalyst.  Other experiments illustrate the uncontrolled reaction, for example, when the polar solvent is omitted.

Title: Improvements in and relating to electric switches
IPC: H01H1/18
Filed: 1926-08-13
Abstract: 280,294. British Thomson-Houston Co., Ltd., and SaIisbury, A. G. Aug. 13, 1926. Push - button switches, particularly for the starting motor of automobiles, comprise a push-button which through a spring operates a bridging contact member which after it engages the fixed contacts is caused to rotate by further pressure on the button and thereby caused to rub upon the fixed contacts and maintain the surfaces clean. In the arrangement shown in Fig. 1, the non-rotatable button 6 has secured upon it a plunger 1 guided at its lower end in an aperture 12 in the casing and formed with a helical slot 14 with which projections upon the surrounding movable contact disc 2 engage. Springs 15, 10 are interposed between the button and the contact disc and between the disc and the bottom of the casing. When the button is pressed the disc and the spring 15 move downwards together until contact is made with the fixed contacts 3, if pressure is maintained on the button, the disc is caused to rotate upon the fixed contacts. If pressure is removed, the disc returns to the off position. In a modification, the helical groove is formed in the button and co-operates with projections on the casing while the contact disc is capable of longitudinal movement only in relation to the plunger.
