Title: Improvements in or relating to Machines for Covering Wire with Silk Cotton or the like.
Inventor: NARIZZANO JOHN
IPC: D02G3/36
Filed: 1919-01-08
Abstract: 130,266. Narizzano, J. Jan 8, 1919. Wire, covering by winding. - A machine for covering wire with silk &c., of the type comprising flyers rotating on an horizontal or substantially horizontal axis, is arranged with a series of pairs of spinner heads t one in advance of the other, each pair being provided with a separate drive from the main shaft b, comprising a cord x, a pulley f on the shaft b, pulleys y on the spinner heads, and guide-pulleys w. Spare bobbins of covering-material are placed on holders 8, 10 in front of each spinner head. The wire is led from a spool 14 on a support 13, through the spinner heads t and bobbin holders 8, 10, and out over a guide-pulley 10, once round a grooved wheel m, and through a traversing-guide 18 to a winding-bobbin 6. The bobbins 6 are separately driven by cords 7 passing over guide-pulleys 4, 5 and the corresponding grooved wheels n, which are on a countershaft c driven from the main shaft b. Means are provided for varying the relative speeds of the flyers and the winding-bobbins, and comprise a train of change-speed gears on an arm movable radially about the main shaft b and a belt drive between a pulley on the countershaft c and an interchangeable pulley on the shaft of the last gear in the train, the arm being adjusted radially to compensate for slackening of the belt when the pulley is changed. The traversing-guides 18 are mounted on a rod 29 reciprocated by a crank mechanism operated by worm gear from the countershaft c.

Title: Improvements in or relating to processes for preparing crystalline penicillin in the form of its ammonium salt
IPC: C07D499/14
Filed: 1946-01-08
Abstract: Pure crystalline ammonium penicillin is prepared by dissolving dry amorphous ammonium penicillin in water or an alcohol, ketone, aldehyde, acetal, hydroxy ether, hydroxy ester or cyclic ether, cooling until the solution is saturated and standing until crystalline ammonium penicillin separates.  The impure amorphous ammonium penicillin may be prepared by treating an organic solvent solution of impure penicillin with active carbon, converting to the ammonium salt, e.g. by extracting with aqueous ammonia and drying the resultant aqueous solution of ammonium penicillin. Penicillin salts of metals of sub-divisions A of groups I and II of the Periodic Classification are prepared from the pure ammonium salt by converting to the free penicillin acid and treating with a hydroxide or carbonate of one of the said metals to give the penicillin salt of the metal which may be separated by freeze-drying.  Suitable solvents for recrystallization of ammonium penicillin are methyl-, ethyl-, n- and iso-propyl, n-, secondary- and tertiary butyl-, n-hexyl-, capryl-, octyl- and 2-ethylhexyl-alcohols; diethyl carbinol, acetone, methyl ethyl ketone, 1 : 4-dioxane, 1 : 3-dioxolane, dimethyl acetal, allyl alcohol, 2 : 2 : 4 : 5-tetramethyl-1 : 3-dioxolate, butyl lactate, 2-methyl-2 : 4-pentanediol, ethylene glycol monobutyl ether, methyl levulinate, benzaldehyde, cyclohexanone, cyclohexanol and methylal.  In examples, impure ammonium penicillin is recrystallized from (1) isopropyl alcohol; (2), (3) and (4) a mixture of isopropyl alcohol and tertiary butyl alcohol; (5) each of the organic solvents listed above; (6) n-butyl alcohol; (7) n-hexyl alcohol; (8) 1 : 3-dioxolane; (9) 1 : 4-dioxane, and example (10 ammonium penicillin prepared according to the previous p  examples is converted into penicillin acid which is treated with dilute aqueous caustic soda to give sodium penicillin.

Abstract: 784,122. Generating combustion products under pressure. BRITISH THOMSON-HOUSTON CO., Ltd. Jan. 6, 1956 [Jan. 12, 1955], No. 989/55. Addition to 784,121. Class 51 (1). [Also in Group XXVI] A combustion chamber as claimed in the parent Specification in which a monofuel is decomposed to form a gaseous working medium for a prime mover and in which the pressure required for the initial fuel injection and the heat necessary for starting he decomposition of the monofuel are obtained from the burning of a deflagrant in a breech and having a pressure intensifier connected to the combustion chamber the increased pressure from which is used for at least the initial fuel injection has the breech connected to the combustion chamber through a conduit containing a restricted orifice and the side of the orifice nearer the breech connected with the pressure intensifier. The breech 2 is connected to the combustion chamber 1 by a conduit 3 containing an orifice 5. The conduit 3 upstream of the orifice is connected to the low-pressure side of the intensifier 4 by a conduit 6. The fuel is discharged into the combustion chamber 1 from the high-pressure side of the intensifier. The orifice 5 should have an area of between 60 per cent and 85 per cent of the area of the exhaust nozzle of the combustion chamber and should preferably be 80 per cent of that area. The orifice increases the operating pressure of the intensifier. When decomposition is established in the combustion chamber, the pressure in the chamber 1 will be supplied to the intensifier 4 through conduits 3 and 6. As the rate of flow will be small, the orifice 5 will then have a negligible effect.
Patent HK-20293-A (HK)
Title: Coin testing apparatus
Inventor: DEAN ROBERT
IPC: G07D5/08
Filed: 1993-03-11
Abstract: The operation of a coin testing apparatus is checked by switching the apparatus to a test mode. In the test mode, the properties of items inserted into the apparatus are compared with stored «test» ranges, instead of «acceptability» ranges which are normally used to determine whether the item is a genuine coin. A specially designed non-genuine coin is then inserted into the apparatus. If the measured properties of the non-genuine coin fall within the «test» ranges, a signal is produced to indicate that the apparatus is operating correctly. If any of the properties falls outside a «test» range, but within a further, contiguous range, a signal indicates that the apparatus is working adequately, but not optimally.

Abstract: PURPOSE:To make a switchgear super-compact requiring no pressure container, and improve safety and economy by containing three phases of high voltage electric appliances including a vacuum valve as a whole in a container and filling the empty space of the container with silicone gel and silicone rubber balls in which insulating gas is sealed up. CONSTITUTION:A vacuum valve 14 for switching, a vacuum valve 15 for cutting a circuit, arrestors 16a, 16b, electric detecting appliances 17a-17c, and other conventional electric appliances of switchgear in a pole are contained in an electric appliance storage chamber 13 of a tank 11. The empty space among the electric appliances in the electric appliance storage chamber 13 is filled with a silicone rubber (rubber ball) 23 in which SF6 gas or N2 gas is sealed up and silicone gel (gel) up to the level A shown with an one-point-dotted line from the bottom. Insulated cylinders 20, 20 are also filled with the rubber ball 23 and gel up to the level A. In this way, switchgear is made super-compact and appearance and environmental harmony of the pole to which the switchgear is attached are improved and further not like a conventional one, the switchgear does not need air-tightness, and compactness and simplification is achieved and economy is improved owing to the simply closed type.
