Abstract: 1376514 Laminates ALUMINUM CO OF AMERICA 28 Sept 1972 [19 Oct 1971] 44899/72 Heading B5N [Also in Divisions B3 and B8] A method of fabricating a container wall, e.g. a can end adapted to be provided with an integral opening device, e.g. a pull tab 14 riveted to the can end, comprises providing a metal sheet 22, e.g. of aluminium or steel or an alloy thereof having an adhesive material 24, e.g. an epoxy resin, a polyester or a polyurethane secured to one surface thereof, serving to secure to the metal sheet a continuous protective layer 26 of a partially crystalline polyolefine, a partially crystalline ethylene-olefine copolymer, a copolymer of ethylene with an acrylate or an ionomeric ethylene copolymer, scoring the metal sheet, e.g. around score line 8 to define a sector which is completely severable from the remainder of the container wall or partially severable and displaceable sufficiently to permit access to the contents of the container, while preventing fracture of the adhesively secured protective material and subsequently heating the composite sheet to a temperature of 275 to 375 F. for a period of 0À2 seconds to 4 minutes to stress relieve the protective layer and substantially eliminate microvoids established in the protective layer during the scoring operation. In a preferred embodiment, an integral upwardly directed rivet 20 is formed in the sector within the score line and heating is subsequently effected at a temperature of 300 to 350 F. for a period of 0À5 to 3 minutes. The score line may be formed using an anvil and an indenter tool.

IPC: C08G65/18
Filed: 1962-11-29
Abstract: A catalyst comprising water and an organo aluminium compound is used in the polymerization of oxacyclobutane and derivatives thereof of the type <FORM:1024815/C3/1> where X and Y may be hydrogen, alkyl, aryl, nitro, cyano, alkoxy, alkoxycarbonyl or acyl groups, or have the formula -(CH2)nZ where n>1 and 2 is a halogen, hydroxyl, alkoxy, amino, acylamino, acyloxy, acyl or cyano group, and the organo aluminium compound has the formula R3- nAlXn where n is 0, 1 or 2, and R is an alkyl, aryl, cycloalkyl or aralkyl group, and X is a halogen, alkoxy, acyloxy or secondary amine group.  The molar ratio of water to organo-aluminium compound ranges from 0.01 to 3.0:1, and is preferably 0.1 to 2.0:1.

Title: Orienting articles
IPC: B65G47/244
Filed: 1971-10-01
Abstract: 1395722 Conveying and orientating articles; orientating containers for packaging MARDON SON & HALL Ltd 18 Sept 1972 [1 Oct 1971] 45711/71 Headings B8A and B8C A ferromagnetic container 20 has a reflective strip or reference mark 22 which is used to orientate the container while being carried by a conveyer 10. A block 29 alongside the conveyer houses a strip light 31 and a sensor consisting of a series of photo-cells 30a-30d, together with an electromagnet 34. A series of electromagnets 36 is provided beneath the conveyer and the magnets 34, 36 are controlled by the photo-cells 30 through a logic-memory circuit 35. In operation, the circuit maintains the electromagnet 34 switched on so long as no signal is received from any of the photo-cells 30. These are energized only when the reflective strip 22 of the container is facing the block 29, i.e. the container is correctly orientated. With the container in position 20a, or 20b, and its strip indicated at 21, the container will be attracted by the magnet 34 to wall 12 of the block 29 and will be rotated thereby until it moves to position 20c: the magnet 34 is then de-energized and remains so until the container passes a photo-cell 32 which causes the magnet to be re-energized to orientate the next container. If this happens to be correctly orientated the photo-cell 30a causes the magnet to be deenergized and the container is not rotated. The magnets 36 are energized when the magnet 34 is switched off and prevent rotation of the container. For sensing the orientation mechanical or electrical means may be used in place of the photo-cells. As an alternative, the circuitry can be arranged so that a photo-electric cell or other device only produces a signal when it does not sense the reference mark on the container, and rotation of the latter depends on the presence of the signal. Containers of polygonal cross-section are specified and packaging of containers is referred to.

Abstract: 1,090,439. Irradiation of packed samples. APPLIED RESEARCH LABORATORIES Inc. Nov. 1, 1965 [Nov. 19, 1964], No. 46075/65. Heading H5R. In the analysis of a flowable material i.e. a solid liquid or paste, a quantity of said material is placed in a bag, the bag sealed and the bag and its contents exposed to radiation to cause the materials to emit X-rays which are subject to spectrometric analysis. The material of the bag is such that it is substantially unaffected by radiation and exhibits a low response in those portions of the X- ray spectrum of interest in the materials analysed. The preferred material is polyethylene terephthalate sheet. When the bag is exposed to radiation the surface of the bag is preferably flattened in register with an opening of the housing of the X-ray analysis instrument. The bags of materials are preferably prepared in a bagging machine 14, stamped with identifying characters and sealed in 18 and transported by conveyer 20 to the window of the X-ray analysis instrument 22. Where the conveyer stops, an hydraulic platform 30 is elevated to press the bag against the window which is protected with a radiation transparent screen 29. The material is irradiated and the emitted X-rays analysed, when the conveyer moves on to discharge the analysed sample.

The coil is held in its zerc position by an electrostatic, electromagnetic or permanent magnet field The instrument can be used for the remote indication of damper positions, water levels, pressures, specific gravities, velocities of air, steam or liquid by converting a movement into capacitance variations. The moisture content of materials of known dielectric constants can also be measured. The instrument may function as a relay and its movable member may carry a shutter for varying the degree of illumination falling on a photo-electric cell. A yoke 1 has field windings 4, 5 in series with the source 10 on its polepieces 2, 3, secondary windings 6, 7 in series with the moving coil 8 being connected to a reactance 9 to be measured.

Abstract: 1,201,967. Electric calculator; telephone system. INTERNATIONAL STANDARD ELECTRIC CORP. 9 Oct., 1968 [16 Oct., 1967], No. 47844/68. Heading G4A. [Also in Division H4] In a pulse code modulation system providing conference facilities a companding circuit comprises coding and linearizing systems operating according to an approached logarithmic law. The graph, Fig. 1, relating amplitude X as a proportion of permissible maximum to binarycoded compressed signal Y, is made up of a number of straight lines with gradients successively related as 2: 1 on either side of the origin. The highest digit of Y is 1 or 0 according to whether Y is +ve or -ve. In the latter case the code is in complementary form. The amplitudes of the speech pulses of the parties in conference are expressed in linear form in binary-decimal code in register 3, line I, Fig. 3, where the most significant 1 represents the fractional point. At the same time register 4 receives binary 7. Compression then takes place by stepping register 3 leftwards and register 4 down until the position F is reached with the code and mantissa in registers 4 and 3, respectively, the initial 1 in register 3 still representing the fractional point. The value is now expressed in binary-decimal code approximating the logarithm to base 2. Linearization is effected by the reverse process (Fig. 4, not shown). Addition of amplitudes. Fig. 5.-A central control CC receives 7-digit codes a, b of speech values obtained from two parties in a threesided conference. CC then applies a, b to a logical circuit Le in true or complementary form according to whether the highest digit is 1 or 0. Lc and Li from comparison of a and b decide whether the values are to be added or subtracted and whether the result is to be +ve or -ve. The values a, b are then linearized in translator T under control of sequencer S, the resultants being added (or subtracted by complementary addition) in AD and passed back to T for compression. The resultant code is directed to Ls and back to central control CC, which directs the answer to the third party in the conference.
