Abstract: 502,592. Discharge lamps. HANOVIA CHEMICAL & MANUFACTURING CO. June 23, 1938, No. 18663. Convention date, March 24. [Class 39 (i)] A high - pressure metal vapour arc lamp comprises a vitreous vacuum vessel having electrodes positioned in electrode chambers spaced from each other, means for supplying sufficient power to the electrodes to produce a constricted stringy arc in the are chamber of the vessel, and means disposed inside the vessel for deflecting the discharge so that it is close to one side of the vessel and remote from the other side or sides. In the form shown in Fig. 1, the lamp of fused quartz comprises a discharge chamber 4, separated by apertured septums 5 from electrode chambers, in which solid activated electrodes 2 are held by seals 3. The apertures are arranged on a semicircle (the path of the arc) with a radius equal to or less than the cross-section of the chamber 4, so that the arc is maintained close to one side of. the vessel. Alternatively, the tube may be straight, as shown in Fig. 3, and the septums 9, not more than two inches apart, be provided with apertures 10 in line with the eccentrically arranged electrodes. In an example, the filling is mercury and argon, at a pressure of atmosphere or more, and the input 100 watts. The envelope may be other materials transparent to ultra-violet light and the metal vapour may be other than mercury, e.g. cadmium. The lamp is so mounted, in a reflector or otherwise that the side hugged by the arc, and in which most of the deterioration of the quartz will take place, contributes little to the light given out, and this side may be coated with gold or platinum ceramic paints.

Patent GB-596175-A (GB)
Title: Improvements in or relating to automatic weighing machines
IPC: G01G13/00
Filed: 1945-07-23
Abstract: 596,175. Weighing-apparatus. GREGORY, A. H. July 23, 1945, No. 18864. [Class 143] Apparatus for filling predetermined weights of material into containers of different weights with automatic allowance for the weight thereof comprises an automatic weighing machine of the type wherein the weight on the scalepan is balanced against a counterbalance weight rotating about a spindle and having connected therewith an indicator moving over a scale, valved means for filling said material to a container on said scalepan, and automatic means for disengaging said indicator and returning it to the zero position when the valve is closed and for re-engaging it with the counterbalance mechanism when the valve is opened whereby only the weight of material filled is indicated. The weighing machine may be of the type described in Specification 295,432, [Class 143], having a lever arm 4, primary counterbalance weight 6, and arm 7 connected by members 14, 15 to a metal band 13 attached to a drum 8 having a screw 10 carrying a secondary counterbalance 11. Arm 7 may also be connected by a check link to the frame. Drum 8 normally carries a radial indicator arm but is here modified to move a rack 24, through linkage 22, which can coact with a pinion 18 or idler pinion 25 to move an indicator arm 16 on spindle 17. The rack 24 is connected by a strap 26 to a lever 29 freely connected to a cable 31 moveable in a casing 32 and attached to a plunger 33 in a dash pot 34. A lever 37, controlling the valve for the feed of material to the filler orifice in housing 39, carries a cam 36 which, on opening said valve, forces down plunger 33 and cable 31, when rack 24 engages its pinion. Indicator arm 16 remains at zero when a container 2 is placed on the scalepan and moves only after opening of the filler valve to give a reading of the weight of material filled. The lever 37 is then raised to close the valve. Sufficient delay in disengaging the rack is provided to allow material between the valve and container to enter the latter and to give a reading of the final weight. Fig. 2 shows automatic means for shutting the supply valve comprising an insulating arm 40, connected to pinion 18 and carrying a conducting strip 41, and contacts 42, 43 dipping into mercury cups 44, 45 in the circuit of an electric relay operating the valve. Variation in the predetermined weight of material supplied is effected by adjusting the mercury level in cup 45 by tilting a pivoted platform 48, for example by means of a cam and coacting depressions in a sliding bar 53. Automatic opening of the supply valve when a container is placed on the scalepan is effected by providing a further mercury cup 54, and contact 57 which is lowered to close the valve circuit when the rack 24 moves through the intermediary of bell-crank lever 56 and screw 59.

Title: Improvements in or relating to steroids
IPC: C07J41/00
Filed: 1960-07-21
Abstract: The invention comprises steroidal betaines of the general formula <FORM:0933157/IV(a)/1> wherein R1, R2, and R7 represent alkyl radicals containing 1 to 4 carbon atoms, R3 represents hydrogen, or a hydroxy or keto radical, R4 represents a hydroxy, acetoxy or keto radical, R5 represents hydrogen or fluorine, or a hydroxy or methyl radical, and R6 represents hydrogen or a hydroxy or methyl radical, and the preparation thereof by oxidising quaternary salts of the required 18-amino-17-vinyl steroids (which are described in Specification 933,156) at about room temperature with permanganate in water or a water-aqueous miscible solvent, or by oxidising corresponding quaternary hydroxides with ozone and hydrogen peroxide or with chromic acid (with ozone and chromic acid oxidation of secondary hydroxy radicals to keto radicals also takes place). Specification 933,155 also is referred to.

Title: Improvements in Devices for Gauging Rifle and like Scores, with Special Reference to Handicapping.
Inventor: TAYLOR HARRY JOHN
IPC: F41J5/16
Filed: 1917-12-21
Abstract: 119,762. Taylor, H. J. Dec. 21, 1917. Targets.-A device for gauging handicap scores on the targets of miniature rifle ranges comprises a series of disks or sectors of different radii corresponding to the handicap and means for centering them over the bullet holes in the usual paper or like targets. A single-piece gauge a, two of which are shown in Fig. 4, is made up of stepped sectors representing diameters from 0.125 in. to 0.35 in. by increments of 0.025 in., and is intended to be used on a target with circles 0.25 in. apart and a 0.25 in. bullet. The gauge is held in a holder e, Fig, 3, having a pin d which is placed in the bullet hole, say at g, Fig. 4. This hole misses the carton line by 0.025 in., and in rotating the gauge the sector No. 1 just touches the carton line. Thus, gauging with this sector virtually increases the radii of all the target circles by 0.025 in. Similarly gauging with sector No. 2 virtually increases their radii by 0.0,5 in. and so on. With a hole K which overlaps the carton line by 0,025 in. this shot would just score 10 it the carton circle were reduced in radius by 0.025 in. Thus, gauging outwards from the centre of the target, No. 1 sector has the effect of reducing the radius of the target rings by 0.025 in., No. 2 sector by 0.05 in., and so on. A suitable handicap is given by taking a target of ten shots, neglecting the widest two, and gauging the worst shot among the remaining eight. The number of the sector which thus fails to make that shot a carton gives the handicap. Two other forms are described, namely, (1) a celluloid sheet which has sectors of circles marked upon it and a hole for centering, and (2) a series of separate complete disks which may be clamped to a handle and pin.

Abstract: 1,171,056. Reciprocating pumps. BENDIX CORP. April 23, 1968, No.19142/68. Heading F1A. After an inlet passage 36 in the pump cylinder 26 has been closed by the pump piston 28 during its forward stroke, liquid drawn in via an inlet port 18 and inlet passages 36, 38 is pumped to an outlet port 20 via an outlet valve 40, passages 58, 60 in a stepped piston 44, an annular chamber 48 between the stepped piston and a collar 46, and a passage 50 in the collar. If the outlet pressure exceeds a predetermined value, it acts on the stepped piston 44 to move it to the left against the action of a spring 54, thereby carrying the cylinder 26 to the left. This delays the closing of the inlet passage 36 by the pump piston 28 until a later part of the forward stroke. If the cylinder 26 is moved sufficiently to the left, the inlet passage 36 cannot be closed by the piston 28, and pressure cannot then be built up within the pumping chamber 34.

Title: Apparatus for delivering viscous fluids
IPC: B67D3/04
Filed: 1957-06-18
Abstract: 818,851. Apparatus for delivering viscous fluids. ELLINGHAUS, W., and HILGERS, H., [trading as BENZ & HILGERS MASCHINENFABRIK]. June 18, 1957 [June 23, 1956], No. 19151/57. Class 102(1). A device for delivering and filling viscous fluids such as ice cream, or melted cheese comprises a rotary body 3 having a trough shaped recess 4 and a separate duct 7 extending from the circular face of the body to an end face at the level of the axis of rotation of the body. A member 9 is secured to the body 3 by screw 10 and continues the duct 7 by a passage 13 to an outlet nozzle 8, preferably formed as a swan neck. In operation the viscous fluid is fed by a feed worm from a supply funnel 2 and recess 4 to a measuring cylinder (not shown) during the suction stroke of the piston in that cylinder, the rotary body is then moved so that the duct 7 communicates with the cylinder and the material is ejected through duct 7 passageway 13 and nozzle 8. The rotary movement of the body 3'causes an equal rotary movement to the outlet nozzle 8 which dips into the packing to be filled in the ejection position. The position of the nozzle 8 may be adjusted relative to passage 13 by releasing lock nut 14, and the member 9 may be adjusted angularly relative to the body 3 by means of an arcuate slot cooperating with the screw 10. The rotary body is prevented from moving axially by a clip 16 pivoted about 15 which also allows removal of the body for cleaning. The member 9 is also provided with plug 12 to allow cleaning of the passage 13. The rotary body is oscillated through a link 20 connected to the driving means of the piston the arrangement being such that after ejection the piston starts its suction stroke while the measuring cylinder communicates with the duet 7 thus preventing dripping from the outlet nozzle.

Title: Improvements in the manufacture of ketene, acetic anhydride or a homologue thereof
IPC: C07C51/56
Filed: 1936-07-13
Abstract: In the production of acetic anhydride, ketene or a homologue thereof by thermal treatment of aliphatic vapour in the presence of phosphoric acid, or a substance yielding phosphoric acid, the phosphoric acid or substance yielding it, is introduced into the substantially anhydrous acid vapour as an aqueous solution. Ammonia or an organic nitrogenous base may be used in addition to the phosphoric acid as described in Specification 317,907, [Class 2 (iii)].  The catalyst may be dissolved in water, which may contain some acetic acid.  An externally heated reaction tube may be provided with internal baffles, which may also be provided in the preheater. The anhydride and/or ketene may be recovered from the reaction vapours in any suitable manner; for instance the vapours may be cooled to condense all except the ketene; or may be condensed fractionally to separate the anhydride from water and ketene; in the latter case it is preferred to employ a liquid such as benzene, toluene, xylene, chlorbenzene or chloroform which forms an azeotropic mixture with water.  In an example an aqueous solution having the composition of triammonium phosphate is led through a cooled branch tube into the tube carrying the heated vapour of acetic acid to the reaction zone.  Specifications 279,916 and 280,972, [both in Class 2 (iii)], also are referred to.
