Abstract: 1,266,944. Packaging machines; reciprocating conveyers. SAC. S.A.S. DI BIANCHI GIUSEPPE. 3 Sept., 1969 [7 Sept., 1968], No. 43509/69. Headings B8A and B8C. A packaging machine wherein goods are inserted between two sheets (7, 8, Fig. 1) of wrapping material includes thermo-welding attachments for securing the two sheets together to form a plurality of adjoining packages, a reciprocating conveyer 26 for conveying the goods and sheets forwardly, the conveyer having a vertically reciprocable clamp 10 for holding the sheets on the conveyer 26 during the forward movement. The conveyer 26 also carries a transversely reciprocable cutting blade 31 projecting through a slot in the conveyer 26. This slot is disposed opposite the clamp 10 and the surface of the clamp 10 facing the conveyer 26 has a longitudinal channel arranged to receive the cutting blade 31. The clamp 10 is actuated by a piston and cylinder assembly 27a whilst the cutting blade 31 is actuated by a further piston and cylinder assembly acting on a pivotally mounted telescopic member 34 on which the cutting blade 31 is mounted, the upper end of the telescopic member being guided by guide rods 36. The machine further includes means for puncturing successive packages so that a duct from a vacuum chamber (20, Fig. 7) is able to communicate with the interior of the package and another thermo-welding attachment (16, Fig. 6) for re-sealing the punctured partially evacuated packages. The gap created in the feed path by the reciprocating movement of the conveyer is bridged by a sheet of material (40, Fig. 8) attached at one end to a part (41, Fig. 8) of the machine's frame and having its other end portion wrapped around a drum (43, Fig. 8) mounted on the conveyer 26. The drum (43) is spring loaded so as to maintain the sheet (40) in tension during the reciprocating displacements of the conveyer 26.

The composition comprising a plastics material with 2-12% by weight of opacifiers is mixed with a lubricant, before being formed into a tube by moulding or extrusion. The tube is passed through two heating zones, one at 750‹F, to remove the lubricant, and the other at 450‹F, to sinter the plastics used. The tube is then quenched in an aqueous spray-bath at a temperature of 50‹F to reduce crystallisation, and so improve the translucency. The plastics used have a refractive index between 1.3 and 1.9, and the opacifiers used have similar refractive indices.

Abstract: 1302380 Sonic gas analysis F C BROOKER 21 Dec 1970 [22 Dec 1969] 62339/69 Heading H4D A method of analysing a gas by comparison with another gas includes comparing the phase displacement of sonic waves propagated through the test gas in a tube or column with the phase displacement of sonic waves propagated through a reference gas in said tube or column, the reference phase displacement being represented by an electrical equivalent circuit. Air containing CO 2  e.g. from glasshouse, public room, tunnel &c. is analysed by being drawn into tube 8 through moisture filler 17 and CO 2  trap 16. Oscillator 1 drives crystal transducer 7 and the propagated sound wave is received by an identical transducer 10. The oscillator output is also fed through a phase shift network 2 to a monostable 4. The transducer 10 output is also fed to a monostable 13. The outputs from monostables 4, 13 are fed to coincidence gate 5 whose output drives a meter 6. The phase shift network is adjusted until the meter reads zero. The tap 15 is changed over to admit contaminated air to the tube wherein the meter will indicate the phase difference between the monostable inputs. Alternatively the phase shift network may include a calibrated variable resistance which is adjusted until the meter reads zero. In either case the calibration may be in ppm. The tube 8 is open to the atmosphere at the far end 11 in order to preserve isobaric conditions for the two measurements. The measurement output signal may be used to actuate an alarm or to control ventilation apparatus.

Abstract: 1304732 Conjugate filaments and fibrillar assemblies TORAY INDUSTRIES Inc 18 June 1970 29573/70 Heading B5B [Also in Division D1] The filaments of a web are multicomponent, most preferably island-in-the-sea, with at least 5 "islands", each island being of 0À001-0À5 denier. The filaments, which may be crimpted, may comprise nylon 6, 66, 610, 7, 8, 9, 11 or 12, polyethylene terephthalate, polybutylene terephthalate, polyethyleneoxy-benzoate, polyethylene, polypropylene, polyvinyl alcohol, polyacrylonitrile, polystyrene, polyurethane, or copolymers thereof. The island component may be one of the above, or polyvinyl acetate, cellulose, polyether, polycarbonate or polyalkyl substituted phenylene oxide. The "sea" component is preferably polystyrene and its copolymers, nylon 6, polymethylmethacrylate and its copolymers and polyesters. It may be dissolved out of the needled web with formic acid, sulphuric acid, benzene, xylene, toluene, dimethylformamide, dimethyl sulphoxide, acetone, water, alcohol or alkali. In Example 1, a styrene/acrylonitrile copolymer as the sea and nylon 6 as the island component were melt-spun. The extruded 16 island continuous filament was taken up at 1000 m.p.m. on a first godet roller and at 3400 m.p.m. on a second godet roller, with a heater plate at 110 C. intervening, air drawn to 2-3 denier, and air laid on to a conveyer belt. An aqueous solution of an antistatic agent was added and suction was applied to form the web and remove excess solution. The fibres had a breaking elongation of greater than 12%, preferably greater than 20% and a strength of 0À2-1À5 gm./  denier. The web fibres were cut by needling with blade carrying lances then entangled with barbed needles. Alternatively, barbed blade carrying lances may be used. The mat was impregnated with aqueous polyvinyl alcohol and dried, the "sea" component dissolved out in benzene, the sheet dried, impregnated with polyurethane in dimethylformamide, immersed in hot water to set the polyurethane, and buffed. Artificial leathers may be produced. Preferably, the island components are imperfectly crystalline, so that they shrink on heating after the web has been needled.

Abstract: 1309542 Liquid level sensor W B BARTON 18 March 1970 [19 Dec 1968] 60440/68 Heading G1H A liquid level sensor includes a pair of electrodes 2 for contacting a liquid in a container; means for applying alternating current across said pair of electrodes 6 a first rectifying circuit arranged to pass one half cycle of the alternating current when the level of the liquid contacts both electrodes; a second rectifying circuit arranged to pass the other half cycle of the alternating current; means for balancing the two rectifying circuits so as to produce a balanced series of positive and negative half cycles of current through the electrodes; and means for indicating that current is passing through the liquid. A pair of liquid level sensing electrodes 2 are connected in series with the secondary coil of step down transformer 6 and the base electrode of transistor 12 through rectifier 8 and resistor 11. The base circuit of the transistor is completed through resistor 18 to the secondary of transformer 6. A second rectifier 10 and variable resistor 14 are connected in shunt across the rectifier 12, resistor 11 and rectifier 8 so that with liquid conducting between the electrodes only positive half cycles pass through transistor 12 but positive and negative half cycles pass through the electrodes thus reducing corrosion of the electrodes. Variable resistor 14 (and a second transistor (20) of different temperature characteristics, Fig. 2 (not shown)) provides an impedance which may be matched to that of the base-emitter circuit to cause the positive and negative cycles passing the electrodes to be equal. In Fig.3 (not shown) the electrodes are connected in parallel to rectifier 8, transistor 12 and to rectifier 10 so that transistor 12 normally conducts but is short circuited (and thus switches off) when liquid bridges the electrodes.

The forward stage is composed of a nose 4 containing lead shot or liquid ballast 9; a payload 10 of radio-reflecting chaff or measuring instruments attached to a parachute; an inner casing formed by two longitudinal shell halves 15; an outer casing 8 also formed by two longitudinal shell halves; further ballast 17 consisting of lead shot or semi-cylinders of sheet steel and also acting as a heat sink; an expolisive actuator 18; a battery 19; a timer 20; switches 21 and 22; and a tail portion 3 which fits over the end 2 of a propulsion stage. When the forward stage separates from the propulsion stage 2, the switches 21 and 22 are closed and the actuator 8 is exploded some time later. This causes screws 35, 42 and 45 to shear, whereupon the forward stage breaks into its separate parts. These parts fall harmlessly to the ground. Springs 49 and 50 separate the shell halves of the casing 8 to release the payload 10. In another embodiment, Figs. 6-11 (not shown), the casing 8 is comprised by several turns of flexible sheet steel which unwind when the actuator is fired.
