Title: Improvements in gas powered fluid measuring and dispensing machine
IPC: B65B3/30
Filed: 1962-06-20
Abstract: 948,604. Delivering measured quantities of liquid. FINESSE PRODUCTS Inc. June 20, 1962 [June 29, 1961], No. 23776/62. Heading B8N. [Also in Division F1] A fluid measuring and dispensing apparatus 30, such as for dispensing various coloured dyes, comprises a fluid reservoir 34, first and second vented measuring chambers 42, 45, connected by a conduit, a conduit 41 connecting the reservoir with the chamber 42 and means 16 for selectively varying the pressure on the fluid in the reservoir whereby, upon increasing the pressure on the fluid in the reservoir, fluid is forced through the conduit 41 to fill the measuring chambers to a certain level and then, upon reducing the pressure, fluid in the system above said level returns to the reservoir while fluid in amounts determined by the volumes of the measuring chambers is retained therein; a valve 46 is provided for selectively withdrawing the fluid retained in either or both of the measuring chambers. The upper end of the measuring chamber 42 is connected to one end of the pipe 41, the other end of the pipe being connected to a pipe 38, 39 which connects with an overflow tank 40. A pipe 50 is also connected with the measuring chamber and the overflow tank. The space above the liquid in the reservoir is connected by a pipe 31 to a manifold 26 which is fed with a pressurized gas, such as carbon dioxide, from a cylinder 21 via a low-pressure tank 25 and valve arrangement 23, 27; a pressure reducing valve 22 is provided. The cylinder contains liquified carbon dioxide which changes into gas upon expansion through the valve 22 and lowpressure chamber 25. In operation, upon actuation of the valves 23, 27 by a switch device 16, gas is fed, via the manifold 26 and pipe 31 into the reservoir thereby forcing liquid into the measuring chamber 42 and, with the valve 46 in the position shown, into the measuring chamber 45, the excess liquid passing into the overflow tank via pipes 39, 41, 49, 50. A leak-off pipe 32 is connected between the manifold and the overflow tank so that after a certain time as determined by a throttle 52, the whole system is filled with the liquid and the pressure in the reservoir falls to atmospheric. The liquid in the pipes, which are positioned above the level of the liquid in the reservoir, then returns thereto under syphon action until the level in the measuring chamber 42 drops below the pipe 50, thus breaking the vacuum. The liquid from one or other or from both the measuring chambers may then be dispensed by suitable rotation of the valve 46. A number of identical systems 30 may be connected to the manifold 26, the reservoirs holding different coloured dyes so that, by suitably actuating the appropriate valves 46 to dispense different quantities of the colours, various shades may be obtained.

Title: Improvements relating to the manufacture of wrappers for packaging
IPC: B65D75/26
Filed: 1950-09-29
Abstract: 689,404. Seaming non-metallic sheets. WINGFOOT CORPORATION. Sept. 29, 1950. [May 19, 1950] No. 23899/50. Class 42 (i). [Also in Group XVII] Flat, rectangular wrappers consisting of two or more plies of heat sealable film with two only of their opposite edges united are made by apparatus comprising a table 5 over which the requisite lengths are drawn from two or more rollers 3, whereupon a treadle 12 is operated to depress an electrically heated michrome wire mounted between a pair of arms 9 which are pivoted on opposite sides of the table and operate against the tension of springs 11. When brought into contact with the superposed films the heated wire cuts through them and simultaneously seals together the edges on both sides of the line of severance. A notch 14 is provided across the surface of the table immediately below the line of contact of the heated wire and the webs. Although the severance and seaming will ordinarily be effected by a straight wire, a curved wire or blade, or member of other shape may be used. Both films may be of the same width, with their longitudinal edges coincident, or one may be narrower than the other, with both longitudinal edges spaced inwardly of the edges of the wider film. The latter arrangement may be advantageous when the wrapper consists of two films of different thickness, the thinner film being made the narrower. The films may be made of the same or different heat-sealable compositions, e.g. rubber hydrochloride film, vinyl film, polyethylene film or vinyl chloride-vinylidene chloride film, &c. and may include different ingredients, such as plasticisers.

Title: A device for the conversion of electrical input information
IPC: H03K19/16
Filed: 1956-08-03
Abstract: 814,994. Digital electric calculating-apparatus. KIENZLE APPARATE G.m.b.H. Aug. 3, 1956 [Aug. 5, 1955], No. 23995/56. Class 106 (1). A matrix of saturable magnetic cores is adapted to convert electrical information and includes rectifiers in the output circuits. As described, a look-up table for multiplication comprises a matrix of magnetic cores aa preferably having a rectangular hysteresis loop, with input row windings wi and column windings wm, reading windings V and output windings A (Fig. 1). The cores are initially set in a normal condition of negative saturation by negative pulses on the row and column wires. The product of a number u by a number x is obtained by pulsing the row line lu and column line mx to switch the core ux. Fig. 2. A pulse on the reading winding V returns the core to its normal condition and provides an output pulse in the winding A which passes to two groups of diodes having outputs at Ar and As where r is the left digit of the product and s is the right digit. These leads pass to stepping circuits, Fig. 3, which provide on separate leads series of r and s impulses representing the product. Means are described (Fig. 4, not shown) for varying the output connections so that logical combinations of the inputs and outputs other than multiplication may be obtained. Pulse series producer, Fig. 3.-A pulse at one of the terminals 101-109 switches a core 121- 129, and this condition is stepped along stages 111-119 of the stepping circuit by pulses applied alternately at terminals A, B. Each time transfer occurs between the stages 111- 119, an output pulse is produced on an output line 170 and, after shaping by a further core 180, appears at output terminals 190. Thus a number of pulses characterized by the particular terminal 101-109 originally supplied, appears at the output 190.

IPC: H02K44/04
Filed: 1962-06-25
Abstract: 976,113. Discharge apparatus. COMMISSARIAT A L'ENERGIE ATOMIQUE. June 25, 1962 [July 3, 1961], No. 24340/62. Heading H1X. [Also in Division H2] In an electromagnetic interaction pump, a region of ionized gas is formed at the entry to the working part 5 of the duct so that an arc discharge, between electrodes 6, 7, forms in the gas and is forced along the duct due to the presence of the transverse magnetic field produced by poles 3, 4 of a magnetic system. Ionization may be caused by applying a D.C. current to produce an auxiliary arc between either two spaced electrodes, perpendicular to the main electrodes, Fig. 2 (not shown), or a single electrode and one of the main electrodes, Fig. 3 (not shown). Ionization in this region can also be produced by means of a highfrequency current either applied between the above electrodes or to a coil wound around the duct inlet. The formation of a hot spot at this point in the duct is prevented by recessing into electrode 6, Fig. 5 (not shown), a second electrode 9 and striking an arc between them, this auxiliary arc then gyrates around electrode 9 due to interaction with the magnetic field and the speed of gyration is adjusted so that it appears in region 8 at the instant when the main arc is extinguished at the end of the duct. The electrodes may be either of graphite or metal and may be water cooled.

Title: Polyazo-dyestuffs derived from barbituric acid and process for their manufacture
IPC: C09B39/00
Filed: 1959-07-15
Abstract: The invention comprises dyes of formula <FORM:0902228/IV (b)/1> where R is the residue of a diazo component containing at least one azo group, and also contains a metallisable group in a vicinal position to the N=N-A group, and A is the residue of a naphthol sulphonic acid bound to R-N=N- vicinal to the hydroxy group the naphthalene nucleus of A being advantageously bound directly to the two azo links, and the heavy metal, especially copper, complexes of the dyes.  The dyes are made by coupling barbituric acid with appropriate diazo components, or metal complexes thereof, the metal-free dyes being subsequently metallised if required.  The dyes may also be made by coupling a diazo compound of an amine RNH2 with the necessary naphthol-azo-barbituric acid component with metallisation of the product if necessary. Preferred are dyes of formula <FORM:0902228/IV (b)/2> where m and n are 1 or 2, R1 and R3 are benzene or naphthalene residues and R2 is a benzene, naphthalene, diphenyl or 5-pyrazolone residue and especially dyes where m is 1, or is 2 and R2 is a 5-pyrazolone residue bound in the 4-position to the R3-N=N-group and in the 1-position through an arylene group to the -N=N-R1 group and particularly dyes of formula <FORM:0902228/IV (b)/3> where n is 1 or 2, R is a benzene or naphthalene residue and R2 is a benzene, diphenyl, naphthalene or 5-pyrazolone residue.  Amongst indicated compounds from which R is derived are aminosalicyclic acid, aniline-2,5-disulphonic acid, nitro- and chloro-anilines, 4-amino- 41-acetylaminodiphenyl- 3-sulphonic acid, 2-naphthylamine-4,8-disulphonic acid, dehydrothiotoluidine mono- and di-sulphonic acids, aminoazobenzene mono- and di-sulphonic acids and compounds obtained by coupling the above azo group free amines with coupling components such as 3-methyl-aniline and 1-naphthylamine-6- and -7-sulphonic acids.  R may also be derived from diamines such as 4,41-diamino-3,31-dimethoxy-diphenyl or from stilbene or triazole or acetoacet-anilide derivatives.  The portion of the dye corresponding to R may also be metallised.  Representative of indicated components corresponding to R1 are 2-methoxy-5-methyl-aniline and 2-methoxy-1-naphthylamine monosulphonic acids unsubstituted in the 4-position.  Copper and nickel are specified metals.  Hydroxyl, alkoxy and carboxy groups are specified metallisable groups.  The dyes colour materials such as wool, silk and leather and especially cellulosic materials such as cotton, linen, artificial silk and regenerated cellulose fibres.  The dyeings may be metallised on the fibre or in the dye-bath.  Examples are provided of the preparation of the dyes and their use in colouring processes.  Green and grey shades are obtained on cellulosic materials.  Specifications 619,969, 644,883 and 744,666 are referred to.

Title: Improvements in check hinges
IPC: E05F3/20
Filed: 1931-08-31
Abstract: 385,665. Check hinges. HIRAKAWA, M., 5040, Oimachi, Ebara-gun, Tokio. Aug. 31, 1931, No. 24416. [Classes 65 (i) and 65 (ii).] In a door hinge incorporating a fluid check, one of the hinge barrels is hollow and has a helical internal projection engaging a helical groove in a member which slides without rotating on a guide fixed to the other hinge member ; the sliding member is attached to a check piston working in the barrel. In the Figure the hollow barrel 5, on the hinge leaf 4 attached to the door, has a helical internal projection 14 with which a member 10 engages. The other hinge leaf 1 has short top and bottom lugs 2, 3, the lower one having fixed to it a plug 8 bearing in the lower end of the hinge barrel 5, while the upper one has an extension 18 bearing in a pair of gland rings at the top of the barrel 5 and forming a guide for the member 10, which is provided with grooves fitting feathers on the part 18 ; the member 10 is thus moved axially in the barrel by rotation of the hinge. The part of the barrel below the sliding member 10 is filled with oil, and a check piston 11 fixed to the member 10 works therein. The piston has a non-return ball valve 27, which opens during the opening movement of the door, and a needle valve 26 which throttles the oil flow to check the closing movement ; the needle valve is screw-threaded and has a flat upper part which engages in the forked end of a rotatable spindle 32 for adjustment. A lower compartment of the barrel contains a closing spring 7, but this may be dispensed with. In a modification, the bore of the barrel is made of larger diameter than the piston for parts of its length, so that the checking action only occurs towards the end of the closing movement and the final closing is unchecked. This check hinge may be incorporated in a double hinge for doors opening to either side.
