Title: Improvements in cinematograph screens
Inventor: HARKNESS THOMAS SMITH
IPC: G03B21/60
Filed: 1953-02-20
Abstract: 746,667. Coated fabrics. HARKNESS, Ltd., A. S. Feb. 11, 1954 [Feb. 20, 1953], No. 4790/53. Class 140. [Also in Group XX] A projection screen having a wrinkled surface is produced by coating a sheet base of a plastic material such as polyvinyl chloride with an elastic paint containing a solvent capable of temporarily softening the sheet base, the coating being effected while the sheet base is maintained under tension and the tension being released following drying of the paint. One or more coats may be applied. After drying, the screen may be again painted under tension, the tension being partially or completely released while the paint is still wet. The paint may contain chlorinated rubber or a vinyl copolymer and aluminium powder or paste. The sheet base is preferably strained more strongly in the direction of the width of the screen. The screen may be made up of a plurality of strips of sheet base with seams running parallel to the height of the screen. Specification 598,286, [Group XX], is referred to.

[Class 18] Fragile goods are packed in a honeycomb of diamond, pear, or other shaped cells, formed by three or more non- intersecting transversely and /or longitudinally corrugated strips of flexible material, any one of which is adhesively secured, alternately, on opposite sides, to adjacent strips, the areas of adhesion being so narrow in a direction longitudinally of the strips, that no cell side is formed thereby when opened out. The corrugations may be straight or wavy. Either or both longitudinal edges of the strips may be undulated or castellated (Fig. 4), or formed with ornamental projections. Plain strips may be interconnected and corrugated collectively. The strips may be sewn or clipped together, or otherwise secured. By making the corrugations on the different strips coincide, the structure may be folded comparatively flat. Several such structures may be placed in a case. The material may be paper, transparent material, &c., cardboard, parchment, metallized paper, &c.

Abstract: 342,549. Discharge lamps. GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, London.-(Assignees of Patent- Treuhand-Ges. fur Elektrische Gl³hlampen, 11, Ehrenbergstrasse, Berlin.) Feb. 18, 1930, No. 5437. Convention date, Feb. 20, 1929. [Class 39 (1).] In order to obtain lights of varying colour from a luminous electric discharge lamp there is introduced into the tube, at predetermined intervals of time, a secondary gas, the discharge through which is of a colour different from that of the discharge through the main gas filling. The secondary gas employed is one which is adapted to be rapidly absorbed or decolourized, either by the discharge or by auxiliary means such as alkali electrodes or alkali cells arranged in the tube, common gases such as hydrogen, nitrogen or carbon dioxide being suitable secondary gases for use in conjunction with a main filling of rare gas such as neon. The secondary gas may be introduced by a Moor-type feed valve which may be controlled automatically by a time switch, or a gas-emitting substance such as lithium hydride, sodium azide or magnesium carbonate disposed within a side tube may be heated electrically at predetermined intervals of time. Carbon dioxide or hydrogen may be used as secondary gases with a main gas filling of nitrogen, and carbon dioxide, hydrogen, or nitrogen may be introduced into a tube containing neon, argon, and a small quantity of mercury. Long luminous discharge tubes may be provided along their length with a, series of spaced means for introducing a secondary gas, the controlling-devices being such that they are operated either simultaneously or consecutively, thereby producing either a rapid and even change of colour along the length of the tube, or giving the effect of a coloured spot moving along a differently coloured ground.

[Also in Division H1] In a method of manufacturing electrical apparatus, one or more electrical conductors are supported in a mould and then concrete is supplied to embed the conductor or conductors, reinforcement means other than the conductor or conductors being provided and arranged to compressively stress the concrete. The stress may minimize the effect of the differential expansion between the concrete and the conductor or conductors. In a machine for accelerating charged particles a beam tube 11 extends through two halves 12, 13 of a yoke and through apertures in steel plates 17, 18; reinforcement rods 19, 21 also extend through apertures in the plates, and coil windings 14 separated by sintered alumina strips extend through the yoke. Tension is applied to the rods 19, 21 and the structure is encased to form a mould, the plates providing its end walls. Concrete is applied and compacted by vibration and/or by vacuum. After the concrete has set, nuts 20, 23, 24 and 25 are screwed on to the rods and the externally applied tension released. In a modification an assembly comprising a beam tube, windings and a yoke are supported centrally within a steel tube into which concrete is supplied under pressure which is maintained until the concrete has set, whereby the tube maintains compressive stress upon the concrete.

Synthetic polymers are spun vertically downwards through a spinneret, the orifices of which are so spaced that their centres are between 3À5 and 10 mm. apart, the filaments cooled by blowing a stream of gaseous cooling medium on to them at an angle of from 80 to 150 degrees to the direction of the movement of the filaments and supplementary heat is continuously supplied to the spinneret during the spinning process, the amount of supplementary heat being regulated such that it is not less than half the amount and not more than the total amount of heat removed from the spinneret by the gaseous cooling medium. The supplementary heat may be supplied by a radiator or by means of a heater in the spinneret. If a radiator is used, it may be aimed at the spinneret or parallel to the nozzle plate. The spinneret is preferably made of low carbon steel having an emissivity greater than 0À3. The process is suitable for use with polyesters, for example polyethylene terephthalate, polyamides such as nylon 6 and nylon 66 and polyolefines such as polyethylene and polypropylene.

Abstract: 779,982. Reservoir pens. SCRIPTO, Inc. Feb. 22, 1956, No. 5557/56. Class 146(3). In a ball-point pen wherein the ball point and reservoir writing unit can be readily retracted within the casing when not in use, the writing unit is secured to a plunger 42 which is depressed to project the unit for writing and then latched, and can be unlatched for return by a spring to its initial position by rotating a cap 28 in either direction. As shown, the cap 28 is rotatably mounted on the end of the rear part 14 of the casing, and has a sleeve 32 fixed thereto and extending within a fixed abutment collar 24. The sleeve 32 is slotted at 36, and opposite the slot is formed with a resilient latch arm 52. The plunger 42 is slidable in the cap 28 and sleeve 32 and has secured thereto a sleeve 44 which extends forwardly within the sleeve 32 and also within the collar 24. A lug 50 on the inner sleeve 44 extends through the slot 36 in the outer sleeve 32 to prevent rotation of the plunger 42, and to limit the retracted movement thereof due to the action of a compression spring which acts on the writing unit which is secured detachably within the inner sleeve 44. The inner sleeve 44 is longitudinally slotted at 54 and at each side of this slot there is a latching notch 56 which is engaged by the spring latch arm 52 when the plunger 42 is depressed a predetermined amount to move the writing unit into writing position. The latch 52 is formed with lateral wings 58 dispersed in a transverse slot 60 in the abutment collar 24, and the walls of this slot oppose the faces of the wings 58. On rotation of the cap 28 in either direction, one of the wings 58 will abut a wall of the slot 60, flex the latch arm 52, and so force the latter from the notch 56 in the inner sleeve 44.
