Title: Improvements in and relating to automatic cap making and applying machines
IPC: B67B3/02
Filed: 1934-03-15
Abstract: 416,276. Mechanism for making and applying caps to bottles &c. ENZINGER-UNION-WERKE AKT.-GES., Pfeddersheim, near Worms-on-Rhine, Germany. March 15, 1934, No. 8229. Convention date, May 19, 1933. [Class 125 (ii).] In a method of controlling cap making and applying machines, the clutch for the cap making mechanism is actuated by a bottle or similar article to which a cap is being applied, to make a cap for the next succeeding bottle. A bottle 1 is fed to the machine, e.g. by a star wheel, and stands on a support 2 vertically reciprocated by a cam. On the bottle is a capping head 3 and centring plunger 4 beneath which is a stamped cap 5. When the bottle is raised, the cap is set on its neck and the plunger 4 is raised to its uppermost limit in the pressure plunger 6, thus actuating an extension 7, and lever 8 fulcrumed at 9 and pivoted at its other end to a link 10 itself pivoted to a lever 11 fulcrumed at 12 and holding back an abutment 13 on a rotatable key. A cam 15 on a shaft 14 can actuate a lever 18 fulcrumed at 17 when the shaft 14 is in motion. A toothed wheel 20 is loose on the shaft 14 and is rotated continuously by a wheel 23 on the main shaft 24. The bore of the wheel 20 has a groove 25. When a bottle has reached its highest position and released the abutment 13, the groove 25 at its next rotation is engaged by a key 22 on a hub 21 fast on the shaft 14 so that the shaft 14 with the cam 15 is set in motion and, the lever 18 and stamping tool 19 are actuated. A lever 27 is provided to transfer the stamped cap from the stamping tool to the capping head. When the bottle is lowered, after capping, the lever 8 is returned to its original position by a spring 28 and the abutment 13 is again held back.

Patent GB-498030-A (GB)
Title: Improvements in gramophones
IPC: G11B25/04
Filed: 1937-03-24
Abstract: 498,030. Gramophones. DEHN, F. B. (Automatic Musical Instrument Co. ) March 24, 1937, No. 8682. [Class 40 (ii)] Relates to devices for controlling a motor which effects the lifting of the pick-up arm of a gramophone after the playing of a record and its return to the starting position. According to the invention, the pick-up arm 10 carries a slide 36 for actuating a switch 41 mounted in the path of the arm and adapted to control means for moving the arm to the starting position, the slide being advanced towards the switch, by means carried by the arm, when at the end of the playing of a record the needle imparts rapid inward movement to the arm or oscillates it by entering an eccentric groove. The switch may, as shown, comprise electric contacts, or may be a mechanical trip device. In the machine shown, a motor 27 is geared to a shaft carrying a cam drum 26 having at one end a flange 25 with a flat portion 30, and having in its surface a groove which is partly semicircular and partly spiral, the latter portion leading to an enlarged portion 29. A pin 28 engaging in the groove is carried by a bracket. 24 extending from the base of the pick-up arm. The bracket carries a plate 33 which overlies a platform 31, and is also provided with lugs 34 which engage in triangular apertures 35 in the slide 36. The slide has ratchet teeth 38, and a gravity pawl 35a is pivoted on the plate 33. When the pick-up arm is in the position of rest, Fig. 2, the bracket 24 engages the high portion of the flange 25, and the slide 36 is suspended on the lugs 34. When the motor 27 is switched on, manually or otherwise, the drum 26 is rotated clockwise until the flat part 30 of the flange allows the pick-up arm to descend after the.spiral part of the cam groove has, by acting on the pin 28, moved the arm 10 inwards so that the needle is over the beginning of the sound groove. The motor 27 is then switched off by suitable means (not shown), and playing begins, the pin 28 moving in the enlarged part 29 of the cam groove. The slide 36 is at this time held up by the platform 31, with the pawl 35a engaging the ratchet teeth 38. At the end of the record, the slide is advanced until a screw 40 thereon closes the switch 41, the forward movement being sudden, when the record has a quick run-off groove leading to a concentric terminal groove, or step by step through the action of the pawl 35a if the terminating groove is an eccentric one. Closure of the switch 41 starts the motor 27 to turn the cam drum reversely and to effect the lifting of the pick-up arm and its return to the starting position. In a modification, the slide 36 has a second set of ratchet teeth coacting with a holding pawl, and a retracting spring is provided.

Patent GB-684757-A (GB)
Title: Improvements in vitamin a derivatives and intermediates and methods of preparing same
Filed: 1949-03-31
Abstract: b -Ionone or its next higher isoprenologue is condensed with a compound of the formula ROOC.CH2C­N, where R is hydrogen or a hydrocarbon radical, e.g. -CH3, C2H5, C6H5, C16H33, C18H37, C7H7 to produce a cyano acid or cyanoester, which is decarboxylated to yield the corresponding nitrile and the latter is reduced with either aluminium hydride or lithium aluminium hydride to the corresponding amine.  The condensation reaction is preferably carried out in a solvent, e.g. benzene, toluene, petroleum ether, acetic acid or propionic acid.  If glacial acetic acid is used, decarboxylation is spontaneous, particularly in the presence of acetamide and ammonium acetate which act as catalysts.  Intermediate and final products are obtained of the general formula <FORM:0684757/IV (b)/1> in which X is <FORM:0684757/IV (b)/2> where Y is <FORM:0684757/IV (b)/3> R being hydrogen, an alkyl group or an aryl group.  In examples: (1) b -ionylidene acetonitrile is prepared by reacting b -ionone, cyanoacetic acid, glacial acetic acid, acetamide and ammonium acetate, with distillation of water from the mixture and reduced to b -ionylidene ethylamine with lithium aluminium hydride; (2) vitamin A nitrile is prepared by a process analogous to (1), using "C18 ketone" in place of b -ionone and reduced with lithium aluminium hydride to vitamin A amine. Reference is made to Specification 634,925.  The Specification as open to inspection under Sect. 91 comprised an example of the preparation of vitamin A nitrile ethyl acetate by reacting "C18 ketone," cyano ethyl acetate, ammonium acetate and acetamide in glacial acetic acid.  This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to separating constituents of coke oven gases
IPC: F25J3/02
Filed: 1947-04-01
Abstract: 639,400. Separating gaseous mixtures. KOPPERS CO., Inc. April 1, 1947, No. 8838. Convention date, July 23, 1946. [Class 8(ii)] Olefines are separated from compressed coke oven gas by cooling, to condense higher boiling-point hydrocarbons, separating the resulting gas, rectifying the condensate to separate methane therefrom, cooling such gas and methane by adiabatic expansion, using such cooling to rectify the higher boiling point hydrocarbon products, evaporating the condensed methane free higher boiling point hydrocarbons to cool compressed gas and rectifying there hydrocarbons to separate ethylene therefrom as an overhead gaseous product. The separation of compressed coke oven gas into a single gas fraction containing hydrogen, nitrogen, carbon monoxide, methane, a pure gaseous methane fraction, a liquid ethane and acetylene fraction, a liquid propane and C4 hydrocarbon fraction and a gaseous ethylene fraction is effected by passing a coke oven gas at 25 atmospheres pressure through a line 18 to a point 20 where it is divided into one portion which traverses a line 22, evaporators 24, 28 and a valved line 34 before entering an interchange condenser 38, and into another portion traversing a line 40 to a point 52 when one portion traverses a boiler 56, cooling coils 60, 62, 64, 66 and a valved line 68 leading to the condenser 38, whilst the other portion traverses a line 44, a heat exchanger 46 and a valved line 48 to the condenser 38. From the combined streams of coke oven gas cold uncondensed gases comprising hydrogen, nitrogen carbon monoxide and methane leave the condenser 38 by a line 82 to traverse a condenser 78, and this gas together with part of the methane gas leaving the top of a column 58 is thereafter expanded at an engine 92 and the cold gas used to cool the condensers 38, 46 and 140 before it is discharged at an outlet 158. Liquid higher boiling-point hydrocarbons from the base of the condenser 38 are rectified in the column 58. Pure cold methane leaves by a duct 84 and may be mixed with the uncondensed gases or having traversed exchangers 38, 46 be discharged at a duct 166, and methane free liquid hydrocarbons from the base are expanded at a valve 94 and also in the evaporator 28 before passing to a rectifier 98 for the separation of ethylene and where rectification is controlled by cooled liquid ethylene, which after traversing a boiler 114 is expanded at a valve 120 and used as reflux. The gaseous ethylene product of the process is discharged at a duct 122. The liquid higher boiling-point hydrocarbons from the base of the column 98 traverse the condenser 24, from the base of which propane and C4 hydrocarbons are withdrawn at a duct 128. and from the top of which gaseous propylene, ethane. and acetylene pass by a line 130 to a rectification column 132 where the gases are separated into a gaseous ethane and acetylene fraction and a liquid propylene fraction, and which fractions after traversing the exchanger 46 are discharged through lines 146, 164 respectively.
