Title: Improvements in the treatment of filaments, foils and the like
IPC: D01F2/28
Filed: 1937-03-25
Abstract: Filaments, foils, and similar materials, particularly those made of cellulose acetate and other organic derivatives of cellulose, are treated with fluids under superatmospheric pressure, while travelling through a substantially closed apparatus, the filaments, &c., <PICT:0492613/IV/1> <PICT:0492613/IV/2> entering the treatment zone through a body of inert liquid under superatmospheric pressure contained inside the apparatus.  One form of the apparatus consists of a single chamber, the floor of which is covered with inert liquid, the filaments, &c., passing upwards through the inert liquid into the treatment zone.  The filaments, &c., may be subjected to mechanical stretching simultaneously with their treatment with compressed fluid. The inert liquid may be water, mercury, or an organic liquid, while the treatment fluid may be a gaseous saponifying agent or merely a stretch-assisting agent, such as steam or hot water.  In Fig. 1, the filaments 15 are passed through the apparatus by means of rollers 10, 11 and 18, stretching tension being applied between rollers 11 and 18.  The filaments enter the treatment compartment 8 through an inert liquid, and are subjected to the action of steam issuing from jets 12.  The inert liquid is compressed by introducing air or other inert gas at valve 25, while the inert liquid may be maintained at a uniform temperature by continuously passing inert liquid in at valve 7 and out at valve 6. Alternatively, the valve 6 may be shut and the inert liquid may completely fill the compartment 9, entering at valve 7 and leaving at valve 25.  In Fig. 2, inert liquid is contained in a \sx-shaped vessel 20, through which the filaments 15 are led with the aid of guides 22.  If required, the filaments, &c. may pass through inert liquid after leaving the treatment zone and before emerging into the atmosphere.  Alternatively, the filaments, &c. may be sprayed with cold water immediately on leaving the treatment zone. Specifications 443,707 and 443,773 are referred to.

Title: Improvements in or relating to electrical condensers
IPC: H01G13/00
Filed: 1942-07-03
Abstract: 559,304. Coating with metals. HUNT, Ltd., A. H., and WHITLEY, C. July 3, 1942, No. 9247. [Class 82 (ii)] In the manufacture of metalized dielectric elements for electrical condensers in which the metalized surface is of smaller area than the d'electric elements, an embossing foil of a width at least equal to the one of the dimensions of the area is applied to a dielectric sheet placed in a press and the foil is pressed on to the sheet by a heated stamping face of such dimensions as to limit the pressure to that area, the foil comprising the backing and the portions of metal foil not adhering to the sheet being torn off. The dielectric sheet may then be cut to the required size. Travelling over a feed table 15 and the lower plate 16 of a press supported on legs 17 is a conveyer 11 provided with holes in its edges which are engaged by pins 13 in drums 12. A strip 18 of embossing foil 18 passes from a supply roller 19 under guide rollers 20, 21 between feed nip rollers 22 to a take-up-spool 23. The press has a plunger 24 carrying a die block 25 in which is an electric heating coil 26, the lower face of the block 25 being of the same dimensions as that of the metal film to be applied to the dielectric sheets. The band 11 is provided with a series of apertures 27 each taking a sheet 28. The drums 12 and the rollers 22 are moved intermittently in unison and each forward movement brings one opening 27 into register with the lower face of the block 25 and when the conveyer comes to rest the plunger 24 is brought down pressing the block 25 into the foil 18 and bringing into contact with the sheet 28 in position. The heat in the block causes the metal in the foil to adhere to the sheet 28 and when the plunger is raised the paper comes away from the sheet leaving the metal cooling in situ on the sheet. On the next move forward of the conveyer the metallized sheet 28 drops on to the support 29 and a fresh sheet 28 is moved into position under the plunger 24. In another form the metal is applied, preferably on both sides by two plungers, to continuous lengths of dielectric material and then the coated sheets are cut out by a separate punch which only operates when the length of material is at rest. In a third form, the metal is applied to continuous lengths by heated rollers which are provided with projecting sections which impress metal in the length of material which then passes between two rotary knives which make transverse cuts across the length in the spaces between the metallized areas, leaving uncut edge bands which are cut off by two further rotary knives so completing the cutting of sheets from the continuous length of material. Specificatdon 503,851 is referred to.

Title: Improvements relating to worm boxes
IPC: F16H3/06
Filed: 1924-04-11
Abstract: 229,895. Cohen, J. E. April 11, 1924. Driving machines.-In worm-box drop-motions for use in lathes &c., the box carrying the worm shaft is adapted to be released to allow the worm to move in an axial direction, so that jamming between the worm and wheel will not prevent disconnection. The box A, Fig. 1, carrying the worm shaft C is pivoted on the driving-shaft B and carries also a loosely sliding spindle H to which is secured a handle I fitting a vertical slot J in the lathe apron &c. K and provided with an extension O fitting a vertical slot P on the box A. An arm L carried loosely on the spindle H or other box part is pressed by a spring M into engagement with a rest K<1> on the apron K and keeps the worm E normally in engagement with its wheel F. To release the worm, the handle I is depressed in its slot J, and a pin N in the spindle H strikes the arm L and releases it from the rest K<1>. When the extension O is lifted from the slot P, the box is free to slide on the spindle H to relieve such jamming, between the parts E, F as may have prevented the fall of the box. The spindle H may be fixed in the box and the handle I be slidable. When the box is in its lowered position, the handle I may be moved laterally in a horizontal slot J<1> in the apron so that the worm E or one of a series of worms on the shaft C may be engaged with another of a set of wormwheels. Fig. 6 shows a modification in which the box A is engaged laterally by flanges T on each side of a cam Q loose on a spindle R and carrying a handle I fitting a slot J in the apron K. When the handle I is depressed, the cam Q releases the box A, which is able to move the cam along its spindle R as soon as the handle escapes from the slot J.

Filed: 1972-02-29
Abstract: 1371263 Retractive switches SWITCHES Inc 29 Feb 1972 [2 March 1971] 9385/72 Heading H1N A switch, for use in a vehicle seat, for example, comprises a housing 150 containing a fixed contact 102 and a movable contact 104 and having two elongated members 108 and 120 extending therefrom, the latter being slidable in said housing, and the former 108 normally supporting the latter 120 spaced therefrom in a substantially planar initial condition and being connected to its distal portion such that deflection by forces applied transversely, as by a person sitting on the seat, causes the member 120 to move longitudinally whereby contact 104 is actuated. As shown member 120 is a stiff wire supported by a spacing member 110 attached to member 120 which comprises a spring metal strip. The contact 102 is offset from the axis of member 120 and the contact blade 104 is shaped (Fig. 12, not shown) to be engageable by an enlarged end 142 of member 120. The device is shown in the deflected condition in Fig. 10, and blade 104 is inherently biased to engage contact 102. When deflecting forces are removed the end 142 urges contact 104 out of engagement with contact 102. The entire actuating means is encased in a flexible sheath 136. To accommodate overtravel and provide automatic adjustment for any permanent set (such as sag in the seat, for example, due to age) a friction coupling between member 108 and 120 is provided. In the embodiment of Fig. 10, this comprises a bowed spring clamp 130 encompassing the end portion 124 of spacer 110 and a small flat plate 126 fixed on the end of wire 120. On overtravel the actuating end 142 abuts the end or bore 144 causing slip between 124 and 126 increasing the effective length of wire 120. On restoration of the switch the contact 104 is urged against abutment 152 causing reverse slip between 124 and 126 to decrease the wire length and maintain switch sensitivity. In another embodiment (Figs. 3 to 6, not shown) the actuating elongated member is a second metal strip (44), instead of wire 120, and the friction clutch is provided at the contacts end by an end-piece (60) spring- clamped to strip (44) and having a slot to receive the moving contact blade with lost motion. Screw (80) and nut (84) are provided in this embodiment to adjust the limits of travel of end-piece (60).

Abstract: 854,911. Colour television. HAZELTINE CORPORATION. March 22, 1957 [April 25, 1956], No. 9529/57. Class 40(3). Relates to a colour-television receiver employing a plurality of cathode-ray units 12-14, Fig. 2, which produce component colour images and project them along converging light paths 20-22 to superimpose on a screen 10. According to one feature of the invention a plurality of reflectors 31-33, Fig. 1a, or 91, 92, Fig. 9a, are provided common to the converging light paths so as to introduce multiple folds in the light paths and permit the receiver to be accommodated in a minimum of cabinet space. According to another feature of the invention, Figs. 4-8 (not shown), the horizontal and vertical deflection coils for cathode-ray tubes 12 and 14 are shaped to produce fields which distort the scanned rasters in such manner as to convert for the keystone distortion which occurs in the projected images due to the use of converging light paths. The deflection coils form the subject of Specifications 854,912 and 854,913 (see Group XL (a)). The cathode-ray tubes 12-14, Fig. 2, are provided with Schmidt optical projection units 16-18, and according to one arrangement, as illustrated in Fig. 2, they are disposed side-byside to project along paths at right-angles to the viewing screen. The desired convergence and superimposition of the projected images is then brought about by tilting tubes 12 and 14 towards tube 13 through small angles #. According to another arrangement projection units 16 and 18 are positioned so that the units as a whole are toed-in to project along converging paths 20, 22. This arrangement results in a lack of focus over the projected images which is corrected by adjustment of the screens of tubes 12 and 14 with respect to the projection mirrors. Specification 765,659 and U.S.A. Specification 2,752,419 also are referred to.
