Title: Glassine lined liquid or semi-liquid container body and method of making same
Inventor: WHALEY BAYNARD REED
IPC: B65D3/04
Filed: 1965-01-16
Abstract: 1,047,111. Spirally - wound containers. SONOCO PRODUCTS CO. Jan. 16, 1965, No. 2043/65. Heading B8D. [Also in Divisions B5 and F2] Containers are formed of inner and outer plies of material wound on a mandrel. The inner ply 33, Fig. 1 (not shown), is of glassine, the edges of which form a spiral butt seam 36. The seam 36 is sealed by a strip 37 of glassine having an adhesive thermoplastic coating on one surface which contacts the inner surface of the ply 33. Body plies 41, 42 of the container are formed from paper, the ply 41 being coated on both sides with adhesive from an applicator 46. A top ply 47 of paper, which has a printed foil label secured to it, is coated on its underside with glue by an applicator 49. The ends of the container are of metal. A section A of the mandrel is heated from a steam source 26 in order to activate the thermoplastic adhesive. A section B of the mandrel is cooled by water from a source 29. The heat from the mandrel section A and the tension on the glassine strips causes the strips to be calendered, further to the calendering in making the glassine, to form an oil impervious inner surface on the body of the container.

Title: Photographic colour printing methods and apparatus
IPC: G03B27/73
Filed: 1961-01-18
Abstract: 952,889. Photo-electric control of photographic printing. PAKO CORPORATION. Jan. 18, 1961 [Jan.18, 1960], No. 2128/61. Heading G1A. [Also in Division G2] In a photographic colour printing apparatus employing an initial exposure to "white" light until a predetermined amount of light of one primary colour has fallen on photo-electric measuring means followed by sequential exposures to the remaining colours,printing is speeded by making the colour balance of the "white" light inversely related to the sensitivities of the emulsion layers and the sensitivity of the measuring means is reduced at the end of the initial exposure to compensate for the different effective sensitivities of an emulsion to light of broad and narrow wavelength spread. On initiation of printing a shutter 40 is removed from and a tinting filter 48 inserted in the printing beam to give the printing light a colour balance inversely related to the emulsion sensitivities. By this means most of the printing takes place in the initial exposure and since the sensitivity peaks of the emulsions are broader than the pass bands of filters used, printing takes less time. Photo-cells 26, 32, 36, receiving printing light through red, green or blue filters 28. 34, 38 respectively and when one has received sufficient light to cause its associated thyratron 78R, G, B, to fire, the tinting filter 48 is removed by a relay 88 opening contact 88A to de-energize solenoid 57. Two of the filters 42, 44, 46 of the remaining primary colours are inserted in the printing beam until the thyratron associated with these colours fires. Since filters 42, 44, 46 limit the bandwidth of light falling on the printing surface 18 without further limiting that falling on the photo-cells, relay 88 also closes contacts 88R, G, B to increase the bias on the thyratrons and reduce the effective sensitivity of the photo-electric system to compensate this.

[Also in Divisions F2 and H3] In a transistor switching circuit controlling an inductive load L such as a clutch in which initially the load is connected to a high voltage source U max., the difference in the avalanche breakdown voltages of the transistors connecting the load to the two sources is made greater than the difference in voltages of the respective supply sources. A control signal U s  is applied directly to a low voltage transistor (or transistors) T 2  and almost simultaneously through an amplifying transistor T 3  and transformer T, to a high voltage transistor (or transistors) T 1 , the on time of which is determined by the pulse duration from transformer T r . When the signal U s  is removed, transistors T 2  block but the induced voltage, added to the voltage U causes transistors T 1  to conduct temporarily to dissipate the induced voltage.

The fibres are formed by melt spinning the polymer, passing the filaments while still molten, after a short passage through air or other gaseous medium, through a medium at a temperature below 100‹ C. which medium is a swelling effect on the polymer when the latter is above its solidification point but not at the temperature of the cooling medium, the swelling effect decreasing gradually with temperature from the solidification temperature of the polymer to the temperature of the cooling medium, and their stretching the filaments formed. With polyamides the cooling medium is preferably benzylalcohol, a glycol, formamide, ethanolamine, gamma - butyrolactone, 1,4- butane diol or N-methylpyrrolidone and with polyesters the cooling medium is benzyl alcohol, cyclohexanol, triethylene glycol, benzaldehyde 1,2-dichlorobenzene, nitrobenzene, gamma-butyrolactone, DMF, aniline or N-methylaniline.

A woven pile fabric, such as Axminster or Wilton has one or more layers 13, 14 of latex or plastics adhesive applied to the top of its pile and successively dried, and backing sheets may then be applied such as scrim 16 and hessian after the application of an adhesive 15. One or both of the layers of scrim and hessian may be dampened before application. Backing layers 17 containing nylon, P.V.C., or polyethylene may also be used. Instead of a woven backing layer, filaments of jute, cotton, synthetic fibres, or mixtures thereof may be applied to the base layer and held in place by an adhesive. The filaments may be undulated in the plane of the backing as they are applied to produce a zig-zag diamond mesh on the base layer, and straight filaments may also be incorporated. A sculptured pile effect may be produced by passing the fabric between a pair of contoured rollers 50, 51 (Fig. 8) or a chain containing contoured links, as the pile is sliced by a band blade 18 between the two base layers.

Separating gaseous mixtures by liquefaction.-In a process of separating the constituents of air by liquefaction and rectification employing expansion without external work, the air is rectified under a pressure intermediate between the initial and final pressures, and the resulting gas or gases are reheated and expanded with external work, the cold thus produced cooling the compressed air. The air is admitted at the point G and passes through the exchanger D to a coil S at the base of the rectifying column; it is then expanded through a valve V and dis-. charged into the top of the column at say 5 atmospheres. The nitrogenous gas from the top of the column flows back through the exchanger and is expanded in an engine M with further cooling, down to say atmospheric pressure. The liquid oxygen in the base of the rectifier is cooled by passage through a coil in the top of the column before it is drawn off. The oxygen may be drawn off in gaseous form and may then operate a second engine. The air may be liquefied successively in two portions as described in Specification 7305/10.
