Patent GB-135232-A (GB)
IPC: F22D1/42
Abstract: 135,232. Marks, E. C. R., (Worthington Pump & Machinery Corporation). Aug. 30, 1918. Feed-water, supplying.-Relates to apparatus, particularly intended for heating and supplying feed-water to locomotives, of the kind in which excess heated water is returned to the water supply, as described for instance in Specification 13444/03, and consists in controlling the delivery of the excess water bv a bucket, which floats in the water passing through the heater, and which is lowered by the weight of the excess water. Water from the supply-pump D enters the heating chamber A through a spring-closed spray valve 15, and is brought into contact with steam entering the chamber through the check valve 12. The steam is distributed around the chamber by a baffle 14. The heated water falls into a tank B containing a bucket b controlling the discharge of excess water, the water normally overflowing from the tank through side passages 24 into the storage tank C, from which it is withdrawn by the feed-pump E. When the water collects in the tank B faster than it is withdrawn by the feed-pump, it overflows into the bucket, which then sinks and opens ports 2 on the guide stem 20, thus allowing the excess water to enter a passage 21 opening through a valve 7 into the suction side of the supply-pump, the passage 21 and the pump-discharge passage 16 are in communication with closed passages 22, 17 forming air chambers ensuring a regular flow of water. The heater and the pumps are secured together to form a single unit.

Title: Fume cupboards for chemical laboratories
Inventor: REGENSCHEIT BRUNO
IPC: B08B15/02
Filed: 1967-03-22
Abstract: 1,146,778. Fume cupboards. H. KRANTZ VERWALTUNGS G.m.b.H. 22 March, 1967, No. 13554/67. Heading F4X. A fume cupboard comprises a cabinet which incorporates a work-table 1, an opening 5 at the front closable by a slidable sash window 4, an exhaust duct 2 adjacent the back wall, and an inlet opening 11 in the top adjacent the sash window, so arranged that fresh air entering through the inlet 11 is deflected into the interior of the fume cupboard by a baffle 8 on the bottom edge of the sash window, and along with air that enters through the opening 5 ventilates the cupboard before extraction therefrom through the duct 2. The inlet opening 11 is shown in the form of a convergent-divergent Venturi duct extending across the full width of the window, thus causing the entering fresh air, when deflected by the baffles 8 to form a revolving barrel-shaped vortex 9 in the upper part of the fume cupboard, thereby separating the window opening 5 from the air motions in the upper part of the cupboard interior 3. The volume of inflowing fresh air is determined by the relatively low pressure inside the fume cupboard and by the cross-section of the exhaust. To remove the vapour-charged exhaust gas through the exhaust duct 2 as quickly as possible, discharge slots 16 in the form of Borda mouthpieces are arranged along the top, back and side walls. In another embodiment (see Fig. 3), the volume of fresh air admitted is not determined by the sub-atmospheric pressure inside the fume cupboard, but is forced through by a fan, due care being taken that the inflowing air is only a portion of the outflowing exhaust, and is such that air entering through the opening 5 to make up the difference has a sufficiently high entry velocity to prevent polluted air from forcing its way out of the cabinet.

IPC: C08C1/15
Filed: 1916-09-26
Abstract: 110,566. Ilcken, C. A., and Down, St. V. B. Sept. 26, 1916. Latex, coagulating; india-rubber, purifying. -Rubber latex is treated, so as to prevent partial clotting and to produce a larger yield, with a polyvalent alcohol, such as glycerine, glycol, or a derivative thereof which is soluble in water, such as tri-palmitin-glycerine-ester or other glycerine esters, but excluding sugars and viscose, and with or without subsequent treatment with an alcohol and benzene as described in Specification 8487/15. In an example, a mixture of 1 part of glycerine, pure or in alcoholic solution, with 4 parts of alcohol and 5 parts of water is stirred into latex preferably in proportion of 1/6 oz. of glycerine to 1 gallon of undiluted latex, and the spongy coagulum which forms'within 8 hours may then be treated by injecting into it the mixture described in the prior Specification, 1 oz. to every pound of rubber present in the latex. After a time, the coagulum is removed, pressed, and hung to dry at a temperature not exceeding 90‹ F. The bulk of the soft resins and soluble proteins are removed with the benzine during the process of pressing. It is desirable to allow a certain quantity of alcohol and benzine to remain in the rubber which is said to result in the formation of synthetic rubber. All temperatures above 90‹ F. should be avoided and, after the addition of glycerine, coagulation may be rapidly effected, if desired, by the addition of a coagulant, instead of by the bacteria in the latex as in the process above described.

Abstract: 334,877. Chance, H. M. May 7, 1929. Pneiematic separating.-In the separation of granular materials according to density, the mixed materials are subjected on a support. ing surface to agitation which stratifies them and moves them in a predetermined direction and a high velocity current of air or other gas is passed over the surface so as to increase the movement of the upper lighter layers and cause them to discharge at a different point from the lower heavier layers. The surface may be a table, the. floor of a trough &c. and the agitation and traverse of the materials may be caused by inclining the surface and imparting a shaking movement thereto. Alternatively the agitating medium may be a current of air passed upwardly through a pervious supporting surface. Apparatus for carrying out the invention is shown in Fig. 1. The supporting surface is in the form of a trough 1, the floor 2 of which is stepped at 3 and which is supported by flexible hangers 7 and rollers 8 and reciprocated by an eccentric 5 and connecting rod 4. The materials are fed from a hopper 11 and air from a blower 9 connected to the trough by a bellows 10. At the discharge end of the trough, the lighter materials are blown into the bin 14 and the heavier drop into the bin 15. Another construction of apparatus is shown in Fig. 2.
