Title: Apparatus for puncturing containers
IPC: B67B7/48
Filed: 1962-06-13
Abstract: 969,935. Opening containers. H. O. MOORE. June 13, 1962 [Aug. 21, 1961], No. 22638/62. Heading B8D. Apparatus for puncturing containers has a frame 20 which comprises a standard 21 having a base 22 and a platform 23 for supporting a container, the front of the standard being recessed for receiving the container and stepped to accommodate different sizes. A lever 36 carrying a punch 41 is pivotally mounted at 37 and is slotted at its rear end to form arms 53 and 54 between which extends a helically grooved shaft formed by mounting a helical spring 55 on the upright shaft 56 of a motor 57 secured to the base 22. A V- shaped member comprising a follower bar 65 and crank-arm 67 is secured to the arm 54 and a spring 70 biases the follower to withdrawn position against a stop pin 69. A follower guide in the form of a thin upright plate 72 bent outwardly at 73 is provided. A spring-loaded plunger 86 projects from the upper part of standard 21 and has a rearwardly extending stem 91 to which is secured a cam 92 positioned closely adjacent the spring - loaded plunger of a switch 96. When a container is placed on the support the plunger 86 is depressed and the cam 85 presses the plunger of switch 96 to start the motor 57. Also the stem 91 pushes against an abutment 120 on crank-arm 67 causing the V-shaped member to swing round and the follower 65 to engage the rotating shaft. As the follower moves up the shaft, kept in position by guide 72, the rear end of the lever 36 goes up and thus the end carrying the punch goes down and the punch pierces the can. When the follower moves above the guide the spring 70 jerks it out of engagement with the shaft and the rear end of the lever drops by gravity assisted by spring 75 until the abutment 120 rests on the stem 91. The pierced can is removed and the plunger 86 returns to its original position.

Title: Improvements in or relating to electrically driven timepieces
IPC: G04C1/02
Filed: 1926-09-15
Abstract: 265,485. Juillerat, M. A. Sept. 15, 1926, Driving-mechanism, main spring; electric clocks and watches as described in Specification 249,078, having self-contained means for reenergizing the main spring electromagnetically by means of a circuit having two points of contacts connected in series and operated in succession, and having means for maintaining the drive during such re-energization, are provided with a shunt circuit for the electromagnet, which shunt circuit is timed to close and open so as to prevent sparking at the contacts in the circuit of the electromagnet. As in the prior case, contacts 21, 22 and 24, 25 are in series and close in succession, 21, 22 closing first. The main circuit of the electromagnet 10 re-energizing the spring 15 is 20-21-22-17-14-11-25-24-13 and 27. The contact 24 is connected electrically with a contact 37 coacting with a blade 38 carried bv. but insulated from, the member 17. This contact 37, 38 forms with a high resistance or condenser 39, a shunt across the winding 13. In the sequence given the parts act as follows :-as the spring 15 pulls the parts 14, 17, and 35 to the left, driving the clockwise mechanism, contacts 21, 22 close, contacts 37, 38 open and break the shunt circuit, and contacts 24, 25 close, thus energizing the magnet 10 which pulls the parts 15, 14, 17 and 35 to the right. During this motion to the right the pawl 35 takes over another tooth and contacts 37, 38 close, completing the short-circuit. Immediately afterwards contact 21, 22 opens. Thus sparking is prevented. Subsequently, when the pawl 35 recommences to drive the wheel 30, the teeth on the latter depress the part 36 and open contacts 24, 25. A stop 40 is provided to engage the bar 17 and is so adjusted that when this bar rests against it contacts 21, 22 and 24, 25 are all closed. This stop is to limit the movement of the pawl 35 to the left when the battery 18 is exhausted.

IPC: C07C2/78
Filed: 1958-07-18
Abstract: A process for the production of acetylene by partial oxidation of gaseous or vaporized hydrocarbons and rapid cooling of the reaction gas by the introduction of water into the gas stream comprises introducing water into the gas stream in the form of undivided jets and so selecting conditions that for a gas stream with a dynamic pressure (PD) and a depth of penetration (a) of water into the gas stream, a diameter (d) of the jets and the water pressure (PW) immediately at the outlet openings of the water nozzles, the numerical values of the expression PW/PD x d/a lie between 1 and 15 In a typical example, 20,000 normal metres per hour of methane are heated to 540 DEG  C. in a preheater and 1150 normal cubic metres per hour of oxygen are heated to 540 DEG  C. in a second preheater. After thorough mixing the gases enter through parallel channels into a reaction chamber in which the methane reacts with the oxygen with the formation of a flame. The diameter of the reaction gas at the outlet is 40 mms. and the pressure (PD) is 2.2 X 10-3 atmospheres. The reaction gas is rapidly cooled and a mixture obtained which contains 7.82% by volume of acetylene and 4.28 grams per cu. metre of carbon black.

Title: The manufacture of new alkylated 5:5-phenylethylhydantoins
IPC: C07D233/72
Filed: 1933-12-15
Abstract: 1 - Methyl - 5 . 5 - phenyl ethyl hydantoin is obtained by treating with condensing agents compounds of the formula <FORM:0430283/IV/1> in which R1 is hydrogen or carboxyl or --CO--NH2, CN, --CONHCl, --COO alkyl, --CONH--COOH, --COCl or --CSNH2 and R2 is carboxyl or its specified derivatives, but when R1 is --CONH2, R2 cannot be CN.  As condensing agents may be used acids such as sulphuric, hydrochloric, and hydrobromic acids; alkalies such as sodium and potassium hydroxides, sodium carbonate, calcium oxide, and organic bases such as pyridine, quinoline and dimethylaniline; and salts such as zinc and aluminium chlorides.  Alternatively the concondensation may be effected at temperatures up to 100 DEG  C. or more as by boiling in water or heating in vacuo at 200 DEG  C.  Solvents or diluents may be present, such as water, ethanol, acetone, pyridine or toluene.  In examples: (1) phenyl ethylmethylaminoacetamide, made by condensing phenyl-ethyl ketone with hydrocyanic acid and methylamine, is shaken with ethyl chloroformate, yielding phenylethylmethylurethanoacetamide, which is then boiled with alcoholic potash, the alcohol is distilled off in vacuo and the hydantoin derivative is precipitated by hydrochloric acid; (2) phenylethylmethyl guanidinoacetonitrile (obtained by reacting cyanamide with phenylethylmethylaminoacetonitrile (Example 3 of the parent Specification) in alcoholic solution, concentrating in vacuo and extracting with hydrochloric acid) is boiled in 20 per cent hydrochloric acid solution, whereby the hydantoin derivative is precipitated.  Other methods mentioned are:--heating to 150 DEG  C. the --CO.NH2 derivative of phenylethylmethylamino acetic acid; treating with aqueous potash phenylethylmethylurethanoacetamide; treating with an inorganic or organic base such as pyridine the --COCl derivative obtained by treating phenylethylmethylaminoacetamide with phosgene in pyridine; heating in an inert solvent the --CONH.COOH derivative obtained by treating phenylethylmethylaminoacetamide with phosgene, and then with water; heating in an inert solvent the --CS--NH2 derivative of phenylethylmethylaminoacetamide (obtained by treating phenylethylmethylaminoacetamide with sulphocyanic acid in glacial acetic acid) so as to produce a thiohydantoin, which is then treated with mercuric oxide or ferrous sulphide to replace the sulphur by oxygen; and heating with hydrochloric acid phenylethylmethylguanidinoacetic acid.
