Title: Improvements in and relating to substances transparent to ultra-violet light
IPC: C03C3/16
Filed: 1928-11-03
Abstract: 319,337. Corning Glass Works, (Assignees of Hood, H. P.). Sept. 21, 1928, [Convention date]. Production of metal.-Relates to the method of producing glasses which transmit a high proportion of ultraviolet rays by using batch material which are free from iron and titanium, as described in Specification 263,410. The present invention deals with the selection and treatment of the batch materials. The silica preferably consists of vein quartz which has been crushed and then treated to remove any iron introduced during crushing. In making a borosilicate glass, a boron compound is added to the batch in such a quantity that, in the resulting gases, the sum of the percentages of silica and boric oxide is from 10 to 22 times the sum of the percentages of alkalies, and the percentage of silica is at least five times that of the boric oxide. When iron is present, a reducing material is necessary and carbon, or a carbonaceous compound, is convenient for this purpose. Carbon imparts a yellow or amber colour to the glass, but the addition of zinc oxide neutralizes the yellow colour and the resulting glass has a bluish green tinge. The zinc oxide should be specially purified to remove any traces of lead that may be present. The batch is melted in pots made of fused quartz, or in small tanks constructed of good quality silica bricks. The air and fuel gases used for heating the furnace are preferably filtered, and burners with nickel tips are used to prevent the introduction of iron scale.

Title: Autographic registers and like manuscript devices
IPC: B41L5/06
Filed: 1952-12-19
Abstract: 729,510. Manifolding devices. STANDARD REGISTER CO. Dec. 19, 1952, No. 32315/52. Class 16. [Also in Group XIX] Short strips of carbon paper are interleaved with the record strips of an autographic register or like manuscript device and are secured to a carrier which is adapted to be reciprocated longitudinally of the writing table by the record strip advancing mechanism. Movement of the carrier in either direction is in a succession of short steps, corresponding to successive operations of the strip advancing mechanism, and ensures complete usage of the carbon strips. The initial position of the carbon strips can also be adjusted for the same purpose. As shown, the rear ends of the carbon strips 17 are attached to transverse bars 18 threaded over pins 23 on a carrier 25 extending under the writing table 6 and mounted for longitudinal movement on rails 31 at either side of the casing. This movement relative to the rails is normally prevented by engagement of gears 32 on a shaft 33 extending across the carrier with slots in the rails, a spring detent 36 on the carrier engaging a notched wheel 34 on the shaft to lock it. The shaft may, however, be turned by means of an exterior handle 48 to change the initial position of the carbon strips. The rails 31 are mounted on the casing walls for limited longitudinal sliding movement, and are linked to crank arms 42 on a transverse shaft 44 adapted to be driven through intermittent motion gearing 45, 46 from the hand-driven record strip advancing shaft 13. Thus, each time the shaft 13 is turned to present fresh forms to the writing position, the rails 31 and carbon strips are displaced an increment of their reciprocatory path of movement.

Abstract: 842,750. Feeding and collecting slivers. KAMMGARNSPINNEREI KAISER SLAUTERN Oct. 16, 1957 (Oct. 22, 1956], No. 32366/57. Class 120(3). Fibres supplied in sliver form by one machine and fed to a second machine are passed from the first machine to a conveying mechanism which deposits the sliver in long lengths near the inlet side of the second machine, the sliver being fed direct to the second machine from that point. As shown, Fig. 1, slivers 2-7 delivered by the heads of a drawing frame are combined in a channel 8 to form a sliver band 9 which is conveyed by a conveyer belt 14 to containers 10 at the inlet side of the following processing machine. The sliver band is deposited in zig-zag fashion in one of the containers 10 by a pendulum feed unit comprising oscillating conveyer belts 22, Fig. 3, carried by a carriage 15 which is individually driven so as to reciprocate slowly between limit switches on a runway 12. The sliver band is diverted by a obliquelydisposed guide roller 16 on the carriage on to a conveyer belt 17 leading to belts 22. Belts 17, 22 are driven from a roller 24, Fig. 3, engaged by belt 14, so that the delivery speed of the sliver band is adjusted to compensate for relative motion between belt 14 and carriage 15. When one container 15 is filled, the axis of roller 16 is turned through 90 degrees and sliver is fed via a duplicate set of conveyers 17, 22 to an adjacent empty container while sliver is fed from the first container via guide means to the next machine. Instead of having two containers 10 side by side, any desired member may be disposed behind each other and be filled in succession by a single pendulum feed unit. Alternatively, a single feed unit may serve both longitudinally and laterally adjacent containers by using a runway which is itself movable transversely of the direction of travel of carriage 15.
