Title: Improvements in the manufacture of sheets of thermoplastic fibres for example glassfibres
IPC: D04H3/004
Filed: 1966-01-20
Abstract: 1,134,685. Glass filaments. COMPAGNIE DE SAINT GOBAIN. 20 Jan., 1966 [21 Jan., 1965], No. 2647/66. Heading C1M. [Also in Division D1] Thermoplastic filaments, e.g. of glass, coming from a spinneret 1 are attenuated by a drum 4 about which they pass, stripped from the drum and blown along a guide member 80, 84, the end of which is reciprocated across a moving belt 92 so that the filaments form a web on the belt. More than one guide member may be used to place filaments on the belt at the same point along its length (see Fig. 16, not shown) and a number of guide members may be arranged along the belt to successively place filament on the belt (see Fig. 19, not shown). Powdered glass is fed at an adjustable rate to the spinneret 1 (see also Figs. 14, 15, not shown), and the resulting filaments are fed down a preferably enclosed duct to the drum 4. The duct is compartmented into zones (Fig. 9, not shown) and the central zone is provided with adjustable slots through which air may be drawn by the low pressure region created at the opening of guide 5 by the nozzle 9. The portions of the duct adjacent the spinneret are of asbestos. Adjustable guide members 5, 6 enclose the drum surface along which the filaments pass and between them is a nozzle 9, adjustable in position, inclination and speed of air delivery. A plate 10, inclined to a radial plane of the drum at 30-60 degrees deflects the air current from guide 6 so that the filaments are stripped from the drum and fed into a guide 80. A flexible plate 11 co-operates with plate 10 to form a channel and guides 12 at either side of the channel are adjustable in position so that the width of the filament band placed on guide 80 is adjustable. Guide 12 may be arranged to produce a narrow band or strand to be laid as reinforcement on a previously formed web. When the apparatus is being started up, filament (50), Fig. 10 (not shown), with drops (51) at the bottom thereof pass from the spinneret. The drops engage an inclined moving belt (62) formed by bars (63) to be carried under the drum (4) so that the filament engages and is severed by a knife (59) mounted on the end of the guide (5). The drop (51b) with a portion of filament (50b) is then ejected from the end of the belt (62) while the free end of the severed filament is drawn between drum (4) and guide (5) to be entrained by the drum, the air being drawn between guide (5) and drum under the effect of the nozzle 9 assisting in the movement of the filament. The bars of belt (62) should be 10-30 mm. apart and the belt is inclined at 20-35 degrees to the horizontal. The belt is horizontally and vertically adjustable and the inclination thereof is adjustable. An adjustable plate (64) is positioned beneath the bars of the belt to support the glass drops.

Multiplex systems. - The frequency bands 1 - - 6 used on one carrier wave line A are staggered in relation to the frequency bands used on an adjacent line on lines B, C, as indicated in Fig. 3, in which frequencies are plotted on the horizontal axis. In this way, the important frequencies occurring at the middle of the bands, as indicated in the lower part of the figure, coincide with the gaps between the bands in the adjacent lines, and the effects of crosstalk between the lines is minimized. When a number of lines are supported on the same poles, the lines are placed in the order ABCAB . . ., in order to obtain maximum spacing between the lines using the same frequency bands. Preferably, only the upper or the lower side band is transmitted on the lines, the carrier being suppressed.
Patent GB-583113-A (GB)
Title: Improvements in or relating to the production of activated carbon
IPC: C01B32/336
Filed: 1941-03-04
Abstract: Activated carbon is produced by subjecting carbonaceous material in a thin layer to the action of steam or other activating gas currents passed through the material alternately in opposite directions, the current from one direction being hotter and that from the other direction cooler than the carbonaceous layer.  In an apparatus shown in Figs. 4 and 5 for carrying out the process air and steam are admitted into combustion chambers 13 p  by means of concentric tubular arms 1, 3 connected to concentric rotatable tubes 16, 17. The arms 3 have jets which project the steam downwards on to carbonaceous material spread on perforated plates 30 spaced from the floor 6 by distance pieces 301 while jets in the arms 1 project air in a direction parallel to the surface of the material.  As the arms <PICT:0583113/III/1> <PICT:0583113/III/2> rotate the steam jets, highly heated by the combustion taking place on and above the material, are forced through the layer and then return therethrough, after the jets have passed over, in a condition cooled by the endothermic reaction.  The alternating effect may be assisted by steam admitted below the plates 30 at a continuous or pulsating pressure from pipes 32.  The rotating arms are fitted with ploughs which agitate the material and facilitate its passage from stage to stage through openings 14 to the outlet 15.  Specifications 446,505 and 546,531 are referred to.

Title: Lathe for turning work of non-circular cross section, for instance workpieces havingthree or more corners and in particular roll ingots
IPC: B23Q35/10
Filed: 1933-01-31
Abstract: 397,765. Copying-lathes. GESSER, F., 20, Hermelsbacherweg, and HœBER, H. 2 Vinckestrasse, both in Siegen, Westphalia, Germany. Jan. 31, 1933, No. 3037. [Class 83 (iii).] A lathe for turning non-circular work-pieces such as an ingot x comprises a tool support 1 movable around a pivot bearing 8 mounted on a cross slide 12 which is carried by a carriage 4 movable longitudinally of the work-piece by a leading screw 5, the tool support being rocked about its pivot by gearing y in timed rotation with the rotation of the work-piece. In Fig. 1 the support 1 is adjustably mounted on a plate 10 pivoted to the cross slide which is controlled by guide mechanism consisting of a roller 15 engaging a longitudinal guide-bar 14 which is inclined according to the taper of the ingot. The gear y for effecting the rocking movements of the tool holder comprises a cam 20 slidable on a longitudinal cam shaft 21 and engaging a roller carried by a rocking lever 24 which in turn engages a roller 28 adjustably mounted on the plate 10. Adjustment of the roller 28 to vary the amplitude of the rocking movement is effected by a screw 30 operated by a hand-wheel 29. By moving the roller 28 up to the pivot 25 the rocking movement is reduced to zero and circular workpieces may be turned. When the cross slide is operated by the guide bar in turning a tapered ingot the roller 28 is automatically moved towards the pivot 25 as the tool approaches the work axis, thus maintaining a similar cross section throughout the work-piece. In a modification, Fig. 3, the tool support 1<1> is pivoted at 8 to the cross slide and carries the roller 28 of the gearing y. In this form the axis 8 and the roller 28 move together transversely of the work axis so that the amplitude of the rocking movement is reduced as the tool approaches the work axis. This adjustment may be effected either by means of the guide bar 14 or by a threaded spindle 40 operated through bevel gearing from a handwheel 48. The lever 24 is rocked by means of an oscillating splined shaft 50 operated from a cam driven in timed relation with the workpiece. In order to maintain the tool at the correct cutting angle the tool-holder 60, Fig. 5, may oscillate about an axis 61 which is inclined to the vertical plane E<1>, E<1> passing through the axis 8. In the mid position of the tool support the axis 61 intersects the plane El, E<1> at the cutter point. The shank 63 of the tool-holder is mounted on bearings 64, 65 and is connected through arm 67 and rod 68 to a crank 69 slidable along a shaft 71 driven from the shaft 50.

Electro-mechanical signal repeater and storage equipment includes means for receiving electrical signals from a source independent of a mains supply, e.g. a master clock, and to retransmit them under sole control of the mains supply, e.g. to drive a secondary clock indicator, the incoming signals being repeated as received while the mains supply is available, stored when the mains supply has failed, and retransmitted at a faster speed than that at which incoming signals are received when the mains supply is restored, e.g. to bring the indicator to the correct time. Electric pulses from a master clock each operates an electromagnetic 'pawl and ratchet mechanism' to drive via a gear-wheel (not shown) a gear-wheel 5 screw-threaded on a shaft 3, to move the wheel 5 axially away from a stop 12 to allow the shaft 3 to be rotated by a mains operated motor 2 via gear-wheels 11, 10 and a clutch 4. As the shaft 3 rotates a cam-plate 6 thereon closes contacts 8 once for each pulse received from the master clock to operate one or more slave clocks. If the mains supply fails the shaft 3 ceases to be rotated, and the gearwheel 5 is moved axially along the shaft 3 by the pulses from the master clock for a period determined by the width of the gear-wheel 5, unless during such period the mains supply is restored when the shaft 3 will be rotated continuously to provide slave clock actuating pulses via the contacts 8 until the gear-wheel 5 reengages the stop 12 to cause the clutch 4 to slip. The slave clock, or clocks will then be again synchronized with the master clock.

Abstract: 979,743. Unloading compressors. NORMALAIR Ltd. Dec. 10, 1963 [Jan. 26, 1963], No. 3335/63. Heading F1N. A compressor unloader 1 particularly for unloading the compressor of a refrigeration system, comprises a sleeve valve 10 slidable in a body 2 and controlled by part of the refrigerant pumped by the compressor and supplied therefrom to an inlet 9 in the body 2, which communicates through a portway 7, a hole 8, and a secondary valve 19 to the end face of the sleeve valve 10 whereupon the valve is urged against the action of a spring 13 to the non-unloaded position shown. In this position refrigerent from an evaporator enters the unloader through a port 4 and passes through aligned ports 11, 12 in the sleeve valve 10 to an outlet port 5 connected to the compressor. Unloading of the compressor is initiated by a temperature sensing phial located adjacent the evaporator which operates by mechanical, hydraulic, pneumatic or, as shown, electrical means, the closing of the secondary valve 19 by a member 20. The refrigerant trapped between the valve 19 and the end face of the sleeve valve 10 passes through a bleed hole 14 to allow the sleeve valve 10 to move to the right whereby ports 4 and 5 are obscured by the valve 10 and refrigerant from a condenser is circulated by the compressor through a calibrated minor port 6 in the body 2, and ports 11, 15 in the sleeve valve 10 to the outlet port 5.
