Title: Improvements in closures for jars, bottles and other receptacles
IPC: B65D43/02
Filed: 1920-04-07
Abstract: 150,954. Ingram, A., and Ingram, H. April 7, 1920. Capsule closures.-A metal cap for sealing glass tumblers, bottles, jars, and other containers has a depending flange or skirt shaped or grooved to receive a gasket so that by pinching together in a vertical direction a projecting annulus forming a portion of the walls of the groove, the gasket is compressed laterally against the wall of the container and becomes exposed at its lower end below the skirt of the cap so that it can be easily removed. Figs. 3 and 4 show the closure before and after the sealing operation. The gasket 14 is disposed within an annular beading or groove 13 formed in the lower part of the flange or skirt 12 of the cap 11. The portion 13 of the cap has a downwardly and outwardly diverging wall 15, a wall 16 extending downwardlv and inwardly from the wall 15, and a flange or skirt portion 17 extending downwardly from the lower edge of the wall 16. The wall 16 is of less depth than the wall 15 so that the skirt 17 sets outwardly from the wall of the container 10. The gasket 14 has an inner flat face 19 to engage the container, and surfaces 20, 21, 22 fitting against the walls 15, 16, 17 of the cap. On pinching together the angular meeting, portions of the walls 15, 16 by means of grooved dies 23, the gasket is squeezed outwardly from the groove 13 against the wall of the container and elongated vertically so that its lower edge is exposed below the flange 17, as shown in Fig. 4.

Title: Improvements in and relating to rotating beer bottling machines
IPC: B67C3/22
Filed: 1951-04-27
Abstract: 683,458. Bottling. KRIEGLMEYER, J. April 27, 1951 [April 27, 1950], No. 9848/51. Class 125(ii) In a rotating counterpressure bottling machine for beer in which the reservoir 1, 2 for the beer is kept out of communication with the counterpressure gas supply 13, 14, 6 and the displaced gas conduits 8, 15, 13 and in which the excess pressure above the beer is vented from a central space 4 by a float 12, the reservoir is formed of the shape shown to reduce turbulence in the beer, to reduce the inertia of the rotating parts and to reduce the volume of beer held in the reservoir, which may be lined with thermal insulation to minimize loss of cold. The gas pressure of the beer acts on diaphragms 10, 11 to control respectively the counterpressure at a level rather below the beer pressure and the displaced gas pressure at a level somewhat above the beer pressure. This latter pressure insures that the bottles will not be overfilled.

Abstract: 822,847. Atomizing burners. GENERALE THERMIQUE-PROCEDES BROLA. March 26, 1957 [March 29, 1956; Sept. 26, 1956], No. 9891/57. Class 75(1) A burner comprises a rotary spray nozzle for liquid fuel consisting of two concentric, axially spaced interconnected rotary cups 43, 44 separated from each other by primary air passages. The fuel forms a film on the inside of the inner cup 43 and is atomized at the edges by air flowing between the cups 43, 44 and guided by a diaphragm 49. Secondary air outside the cup 44 is guided by vanes 51 on the end of the cup and deflectors 50 to form a vortex directing the fuel upstream. The fuel feed pump 23 and air supply fan 6 are driven from motor 1 by the shaft 2 carrying the cups 43, 44. The shaft 2 is hollow and forms a fuel supply conduit, controlled by a needle valve 29. A spring-loaded ball valve 40 prevents fuel flow when the motor 1 is stationary, and the air drawn in through dampered inlet 4 passes over and cools the motor windings.

Title: Improvements in or relating to clockwork apparatus
IPC: G04B3/12
Filed: 1938-03-31
Abstract: 501,482. Clocks and watches. ETABLISSEMENTS E. JAEGER. March 31, 1938, No. 9913. Convention date, April 6, 1937. [Class 139] The working energy of clockwork apparatus is given by the release of a gas stored under pressure or a liquid (eg. propane) giving off vapour at higher than atmospheric pressure. The gas can be arranged to periodically wind a short driving spring, or to sustain the movement directly. Apparatus according to the former principle comprises a piston 1, displaceable by the pressure of gas admitted through a valve 3. A sector 15 winds the spring of a barrel 10 which drives the clock train 11. A projection 5 on a cam 6, which is controlled by a blade spring 8, engages teeth in the barrel, and when the spring winds down spring 8 becomes relaxed and releases nose 26 of a three-armed lever 21 thereby opening the valve 3. The latter is closed when a pin 24 is lifted by cam 30. Generating liquid can be stored, in the case of a wrist watch, in links 79, Fig. 5, connected by spiral tubes 80, or, in the case of a pocket watch, in a reservoir surrounding the movement.

The two slots 9, 11 in each upper angle iron 10 are non-aligned and overlap and the slot 9 has a step 8 which causes an acceleration of the folding movement of the upper tray. The ends of the slots 17, 19 adjacent the legs are at different angles to the horizontal. Each rod 15, 16 comprises two rods with their abutting ends connected by notched bushes (20, Fig. 7). The upper ends of the legs are bent inwardly and disposed in a tube 23 of oval section and the end of one of each pair of legs is again bent to prevent turning of the leg. A spring 27 acts between each end of the oval tube 23 and a pair of legs and tends to splay the legs.
Patent GB-726920-A (GB)
Title: Improvements in or relating to steroids and the preparation thereof
IPC: C07J75/00
Filed: 1952-04-21
Abstract: The invention comprises isodehydroergosterol-11,14 peroxide and esters thereof, and a process for forming a peroxide bridge between the 11- and 14-positions of a steroid compound by reacting a steroid compound containing double bonds at the 9 (11)- and 8 (14)-positions with oxygen in the presence of light and a dyestuff photocatalyst as oxidation activator.  A preferred method of carrying out the above process is to dissolve the steroid reactant in an inert organic solvent system and contact the resulting solution with oxygen while maintaining the temperature at not more than about 60 DEG  C. Suitable inert organic solvents are aromatic hydrocarbons such as benzene, toluene and xylene, aliphatic or cycloaliphatic hydrocarbons such as hexane, low or moderate boiling petroleum fractions, cyclohexane, and lower alcohols such as ethanol.  The oxidation activator may be eosin or a dye of related structure.  The 11,14-peroxide may be recovered from the reaction mixture by removing the reaction solvent, removing the oxidation activator by washing the dried residue with a solvent such as methanol, and recrystallizing the peroxide product from a chloroformmethanol mixture.  Further purification may be effected by chromatography in petroleum ether on alumina.  The steroid reactant containing double bonds at the 9(11)- and 8(14)-positions may contain the radical <FORM:0726920/IV (b)/1> such as ergosta-8(14),9(11),22-triene-3b -ol, or the radical <FORM:0726920/IV (b)/2> such as isodehydroergosterol (which may be obtained by hydrolysis of an ester thereof) and its esters and ethers.  Other isolated double bonds may be present in the nucleus of the 9(11),8(14)-steroid reactant, and other side chains and substituents to those referred to above may be present, e.g. instead of an unsaturated aliphatic side chain at C17, a carboxyl, an acetyl, or a spiroketal group or oxygen may be attached to the 17-position. Hydroxyl, ether and ester radicals other than the acetate, e.g. the propionate or benzoate radical may be present at the 3-position.  In the example isodehydroergosteryl acetate-11,14-peroxide is prepared. Specification 720,919 is referred to.

Pipe-cutters. - In a pipe-cutter, the cutting-tool is fixed to a non-rotatable screwed shaft which is movable axially to adjust the tool, by a worm-wheel threaded on the shaft and rotated by a handoperated worm. As shown, the cutting- disc 8 is secured to a cheek 9 integral with a screwed shaft 10 carried in a U-shaped frame 5 fixed to the handle 4. The check 9 engages ribs 27, 28 of the frame 5 to prevent rotation of the shaft 10 which carries a worm-wheel 11 operated by a worm 16. Endlong movement of the worm-wheel is prevented by its engagement in grooves 13 in the frame 5. The cutting-disc is formed with a toothed ring 24 on the cheek 9 by a nut 26 and screwed pin 25. The pipe to be cut is held between rollers 2 on the frame 5 and rollers 1 on a member 3 which is adjustably clamped by a screw 6 to the handle 4 and is guided in a groove at the back of the frame 5.
