Title: Carton forming machine
IPC: B31B17/52
Filed: 1968-06-21
Abstract: 1,237,114. Erecting cartons. PRECISION PRODUCE SPECIALTIES Inc. 21 June, 1968 [22 June, 1967], No. 29693/68. Heading B5D. A carton formed from the blanks shown in Fig. 18, i.e. two end panels E and a base B and sides S hinged thereto, is formed in a die-andplunger mechanism in which pre-glued flaps F i  and F o  are folded against the end panels E. The plunger 18 is operated by fluid pressure and as it begins to descend thrust members 22 thereon engage the upper edges of the side panels E and carry them down into engagement with the base B of the horizontally arranged blank. As the blank descends flaps F; are folded up against panels E by a centre portion 154 of the cavity of the die and flaps F o  are only partially folded up by folding plates 152 that are set back further from the centre line of the die than the portion 154. A valve 238 (Fig. 4) is next actuated and piston and cylinder devices 228 extended thereby rotating shafts 218 to cause arms 222 to fold up sides S against the vertical edges of panels E. An arm on one shaft 218 trips a switch 246 to operate a valve 203 whereby actuators 196, 198 move the U-shaped plates 152 inwardly, to completely fold up flaps F o  against panels E. Since flaps F o  are not pressed against panels E until panels S are vertical the glue on flaps F o  is not smeared or wiped off. The stroke of the die is controlled by stops 110, 112 on plunger 18 and as the die commences to lift rollers 80 (Fig. 10) move up in inclined slots 82 thereby retracting the cross-sectional area of the die and releasing the carton. The carton does not fall immediately but is held by inwardly extended folding plates 152 which retract as the die nears its upper position. The carton then falls on to an outfeed conveyer. The blank comprising panels B and S has its flaps pre-glued and trips a switch as it reaches its position under the die to initiate the forming cycle. The machine can be adjusted to accommodate blanks of different sizes.

IPC: G01C9/12
Filed: 1926-11-25
Abstract: 284,807. General Electric Co., Ltd., and Eden, C. G. Nov. 25, 1926. Levels.-Apparatus for use as a sensitive level &c. comprises a vertical rod the length of which is slightly less than the critical length and which is fixed at its lower end to a base so that a small angular displacement of the base will produce a much larger angular displacement of the upper end of the rod. The critical length is defined as the length of a rod which, when fixed at its lower end, will just begin to bend under its own weight. In the form shown the rod is in the form of a thin wire 1 sealed into a stem 2 clamped into a holder 3 on a base 4. At the upper end of the wire is a very small mass 5. The wire is enclosed in a metal tube having an observation window 8. In another form the wire is in the form of an elongated inverted V, the ends of the limb being secured to the base and the mass 5 being secured at the apex so that it can only move in one plane which is perpendicular to that of the wire. A member as above described may be attached to a light bimetallic strip to magnify the deformations of the latter due to temperature changes; or the rod may itself be a vertically disposed bimetallic strip and will then be very sensitive to variations in temperature.

Title: Improvements in or relating to the handling of containers, especially bottles and jars
IPC: C03B35/12
Filed: 1949-11-23
Abstract: 680,454. Suction appliances for gripping loads. BEECH, F. J. Nov. 23, 1950. [Nov. 23, 1949 ; April 18, 1950] Nos. 30025/49 and 9469/50. Class 78 (iv). In the self-sealing suction appliance shown in Fig. 3, a resilient-washer 28 seals the wide mouth of a bottle or jar 20 evacuated through bores 32, 33 in a pin 21 by which the lifting device is suspended from a plate 24. The washer 28 is guided by a metal bush 30 sliding on an extension 29 of the pin 21 and serving as a leaky seal for the bore 32 until the washer is raised by a bottle to engage the rim 27 of a flange 26 on the pin. The leakage past the bush 30 then evacuates the interior of the rim 27 to sustain the washer. Several such devices may be disposed for simultaneous engagement with an orderly arrangement of bottles in a crate ; each device has a flange 22 held on one of a number of conical seats 23 in a common plate 24 by a spring 25 adapted to yield to accommodate a bottle which is not properly seated in the crate. A pilot boss 35 ensures proper register with the bottle. In a similar device to that of Fig. 3 the bottle is evacuated through vents arranged in the top of a chamber within the boss 35 so as to be sealed by the face of the washer 28 : the bush 30 is omitted. In a further modification for lifting cans by their flat ends the washer 28 is formed as a deep inverted cup with a fairly wide rim for engaging the can, and the bore 33 opens into a chamber shaped as a shallow box housed within the washer and formed in its upper surface with vents which may be sealed by the inner surface of the washer. For lifting bottles with narrow mouths a vacuum cup 70, Fig. 2, is formed with a resilient lip 71 engaging the neck of the bottle and the bottle is aligned with the cup by the sloping undersurface 82 of a spring-biased plunger 73 movable with only slight side play within the cup. The plunger is retained by a rod 74 passing with play through a hole 75 in the base of the cup and carrying a nut 76 adapted to prevent passage of air through the hole 75 to the vacuum connection 79 when no bottle is present. The plunger 73 also prevents a foil seal on the bottle from being raised by the suction. The cylindrical side of a, can may be engaged for lifting by a suction cup with a mouth shaped to the contour of the can.

Title: Improvements in or relating to the production of carbon electrodes
IPC: H01M4/96
Filed: 1954-10-21
Abstract: An electrode, which may be used as a gas electrode, e.g. the oxygen electrode, of a fuel cell, is produced by substantially instantaneously heating a shaped body of carbon to above 650 DEG  C., preferably 700-1000 DEG  C., quenching the body to below 50 DEG  C. in a non-inflammable liquid, and repeating the heating and quenching one or more times.  The electrode has an average pore diameter 10-100 , preferably not greater than 40, and an inner surface are 10-50 sq. m./grm. preferably not greater than 30.  The fuel cell is one where the chemical energy of combustible gases, e.g. hydrogen, methane, carbon monoxide, or mixtures thereof, is directly converted to electrical energy.  A carbon tube is heated in an induction furnace, quenched in cold water, and reheated, when the blowing out of water roughens the tube surface and the carbon becomes porous and activated.  The heated tube is again quenched and the heating and quenching steps are repeated twice. The heating of the carbon body may be effected by passage of a current therethrough.
Patent GB-848354-A (GB)
Title: Improvements in or relating to polymeric compositions
IPC: C08L33/06
Filed: 1957-09-27
Abstract: A composition having good resistance to light comprises an organic polymer subject to deterioration on exposure to light and containing carbon and hydrocarbon with any additional element being chlorine, oxygen or sulphur and, as a stabiliser therefor and in intimate mixture therewith, a second polymer of molecular weight at least 10,000 and containing salicylate units of the formula : <FORM:0848354/IV(a)/1> where n is 0 or 1, said second polymer being present in amount such that at least 0,5% by weight of the composition is salicylate units.  Polymers which can be stabilised include polyvinyl halides, polyvinylidene chloride, polychlorobutadienes, chlorinated polyethylene and chlorinated rubber, sulphochlorinated hydrocarbon polymers, polymerised vinyl esters, polyesters, regenerated cellulose, cellulose esters and ethers, polymerised vinyl hydrocarbons, and polymerised or methacrylic acids or esters.  The salicylate unit containing polymers can be homopolymers of vinyl or allyl salicylate, but are preferably copolymers, suitably with acrylic esters of alcohols of 1 to 4 carbon atoms, vinyl esters of aliphatic acids, or vinylidene hydrocarbons of 2 to 4 carbon atoms.  The salicylate groups in the polymers can be present in the form of chelates with, for example, aluminium, zirconium, zinc, magnesium, beryllium, copper, manganese, iron, cobalt and nickel.  They can be produced by transchelation, using the process of U.S.A. Specification 535,520, by treating the polymer with a chelate of a polyvalent metal with a volatile chelating agent, e.g. 1,3-diketones, b -ketoesters or aromatic a -hydroxy aldehydes and esters.  Additional solvent, such as aromatic hydrocarbons, di-n-butyl ether, tetrahydrofuran, methyl isobutyl ketone, cyclohexanone and chloroform is desirably employed.  Chelation can be carried out at the same time as the blending of the salicylate polymer with the light-sensitive polymer.  Examples show the application of the invention to a copolymer of vinyl chloride and p vinyl acetate, to a chlorinated ethylene polymer also containing sulphonyl chloride groups and to polyethylene.  The blends of the polymers can be produced by mixing, milling on hot or cold rolls, of by solution of dispersion mixing.  The light-sensitive polymer and the salicylate monomer can be polymerised and bonded together by treatment with high energy radiation, such as that from a Van de Graaff accelerator.  Specification 807,198 also is referred to.
