Abstract: 527,822. Double windows. STONE & CO., Ltd., J., and CHILTON, A. H. April 21, 1939, No. 12011. [Class 20 (iii)] In a double window comprising dehydrating strips b between the edge portions of the panes a, a<SP>1</SP> sealing material c is applied as a peripheral sealing for preventing access of the atmosphere to the space between the panes, and a metal strip d is provided around the peripheral edges of the panes to enclose the sealing material c. A suitable framework comprises a rubber gasket e and opposed halves f, f<SP>1</SP> of a divided frame held in position by the engagement of dovetail projections g engaging grooves in drift h. The dehydrating material is conveniently asbestos or mill board heated immediately before use. A suitable sealing agent is a molten bituminous material. The metal strip is secured to the edge of the panes by an adhesive such as rubber or rubber-latex cement. In modifications (Figs. 2, 3, 4, not shown), the dehydrating strip b is secured to the metal strip d. In another modification (Fig. 5, not shown), rubber studs are secured to the strip b to hold it frictionally against the panes. In Fig. 6, an inner frame member p accommodates dehydrating strips b<SP>1</SP> in side recesses, the air between the panes a, a' having access to the strips b' through holes r, q and round the sides of frame member p.

Title: Improvements in or relating to lubricating apparatus
IPC: F16N25/02
Filed: 1955-04-26
Abstract: 787,478. Lubricating systems. SCHLOSSHAUER, A. R. April 26, 1955 [April 29, 1954], No. 12035/55. Class 12 (3). A lubricating system comprises a block 2 with two cylindrical spaces 3, 5 containing, respectively, a reversing piston 1 and a preselector piston 4, each having three narrowed portions, the spaces communicating with conduits associated with a plurality of distributers V1, V2, V3, lubricant being pumped through an inlet 13 and, under the control of the pistons, being fed alternately through conduits 17, 19 to the distributers. The narrowed portions of the pistons form chambers which communicate with lubricating points through conduits 20, 21, 25, 26. Lubricant supplied through inlet 13 and conduit 15 forces piston 1 to the right so that lubricant is forced out of conduits 24, 25 to a lubricating point. Lubricant also passes through conduits 14, 17 and forces each piston of the distributers successively to the left. This results in the supply of lubricant in turn to a lubricating point through conduits 19, 20, to a lubricating point through conduits 28, 29, and to a lubricating point through conduits 30, 31. Also lubricant from the right-hand side of the piston in distributer V3 passes through conduit 139 to operate the preselector piston 4 whereby lubricant passes by conduit 140 and conduit 141 to a lubricating point and whereby also inlet 13 communicates by conduit 24 with the right-hand end face of the piston 1. Piston 1 is then reversed so that lubricant is forced through conduits 15, 21 to a lubricating point. At the same time inlet 13 is put into communication with conduit 19 whereby the distributers are reversed, resulting in further supply of lubricant to lubricating points. The distributers are then reversed again to commence a new cycle.

Abstract: 270,747. Motorenfabrik Deutz Akt.- Ges. May 6, 1926, [Convention date]. Addition to 260,584. Cylinders receiving liquid fuel.-In a fuel injection device of the kind in which ignition oil is admitted to a fluid-actuated admission valve b to form a layer in front of the main fuel charge, the pressure in the valve chamber b and in the delivery pipe h for the main feed is reduced before or during the discharge stroke of the ignition-oil pump g by establishing connection between the pipe and a space at reduced pressure. The valve d is opened by linkage connected to the plunger of the main pump a, the pipe e communicating with the suction reservoir or barrel of the main pump. In a modification, the pistonvalve l, Fig. 3, closes the pipe e when the valve d has opened to a certain extent. In a further modification a valve which opens periodically is dispensed with the pipe, h communicating with the pipe e by a restricted opening. A relief valve m mounted in the chamber of the pump g is set to open at a lower pressure than the injection valve to prevent premature injection of the ignition oil.

Title: Process for the production of a tryptamine derivative
Filed: 1959-04-13
Abstract: The invention comprises 6-fluorotryptamine and its acid addition salts, such as the picrate, hydrochloride, and sulphate, and the production of 6-fluorotryptamine by diazotising 2-nitro-4-aminotoluene, treating with fluoboric acid, and heating to prepare 2-nitro-4-fluorotoluene, condensing with ethyl oxalate in the presence of an alkali metal ethylate and isolating the alkali metal salt of ethyl 41-fluoro-21-nitro-phenyl pyruvate, treating with acid to obtain the ester, reducing, and cyclising to form ethyl 6-fluoro-indole-6-carboxylate by the action of a reducing agent in an acid medium; the indole derivative is saponified and decarboxylated to 6-fluoroindole, which is condensed with dimethylamine and formaldehyde to form 6-fluorogramine, which is isolated, quaternised with methyl sulphate and reacted with an alkali metal cyanide; the 6-fluoro-3-indolyl-acetonitrile is isolated and catalytically hydrogenated to yield 6-fluorotryptamine.  6-fluorotryptamine is an intermediate in the synthesis of compounds of the reserpine series, and is an antimetabolite for tryptophane; it may be used when the microbiological conversion of tryptophane to indole is to be avoided, e.g. in pathological intestinal fermentations.

Title: Processes of and means for toughening or hardening glass
IPC: C03B27/00
Filed: 1934-04-27
Abstract: 431,095. Hardening glass. ECKERT, F., 1, Goethestrasse, Charlottenburg, Berlin. April 27, 1934, No. 12802. Convention date, April 28, 1933. Drawings to Specification. [Class 56] Relates to the hardening of glass articles and consists in determining the temperature to which the glass should be heated by observing the change of some physical property of the glass which varies with temperature, a separate determination being made for each article that is hardened. The desired temperature can be determined by measuring the rapid decrease in the electrical resistance of the glass which takes place as the temperature approaches the softening point of the glass. In tempering glass sheets, for example, a sheet is supported in a heating-furnace of the kind usually employed and is gripped between electrodes to which a pressure of 220 volts, say, can be applied. The increase of current through the circuit as the glass is heated can be indicated by an ammeter, or the circuit may include a cut-out or circuit breaker which interrupts or reduces the heating-current of the furnace when the resistance of the glass plate decreases. The desired temperature can also be determined by observing the softening of a specimen of glass which is placed in such a position in the furnace that it is somewhat hotter than the sheet which is being heated. The softening can be indicated by the bending of a rod or bar of glass supported at its ends, or by the sintering of a mass of crushed glass in a container. In the latter case, the temperature at which sintering takes place can be determined by the alteration of the conductivity of the glass. The Specification as open to inspection under Sect. 91, also describes tongs, for suspending a glass sheet, the gripping-points of which form the electrodes by which the indicating circuit is applied to the glass. This subject-matter does not appear in the Specification as accepted.
