Abstract: 1405808 Needle threader NECCHI SpA 26 June 1973 [27 June 1972] 30205/73 Heading DIG In a sewing machine having a cover plate 25 enclosing the head 10 of the machine a needle threading device comprises an elongate plate 30 supporting a threading hook 38 and mounted adjacent an internal surface of the cover plate to be displaceable therealong substantially parallel to the direction of reciprocation of the needle 41 and pendulously displaceable in a first place perpendicular to that surface to bring the hook 38 into alignment with the needle eye and further pendulously displaceable in a second plane to cause the hook to perform a threading movement. The plate.30 has a slot. (31 Fig. 2 not shown) embracing a pin 28 attached to the surface and surrounded by a spring 32 urging the plate against the surface. The upper end of the plate 30 is inclined at 43; the lower end presents a vertical web 33 slidably engaging a slot in the cover plate 25, a horizontal web 34, the hook 38 and resilient needle centring arms 39, 40. In use the operator's finger depresses web 34, the plate 30 sliding past pin 28 until the inclined portion 43 causes the plate to swing to align the hook with the needle eye, a projecting element 44, 45 then abutting the top of the needle bar to maintain the alignment irrespective of the lateral position of the needle bar (Figs. 4 and 5 not shown). The operator then swings the plate and hook forward to enter the needle eye.

Abstract: 535,748. Lifting-jacks. LAKE & ELLIOT, Ltd., and BARRETT, H. R. Nov. 17, 1939, No. 30305. [Class 78 (iii)] In a lifting-jack having a laterally extending bracket 5 normally disposed adjacent to the base of the jack and connected with a nut member 21 slidable on a rotatable screw member 16 in such a manner that the screw is under tension during the lifting operation, the bracket 5 is freely supported on the nut member and the bending moment imposed on the bracket by the load is taken by reaction bearings 9, 10 fitted to the bracket and arranged on opposite sides of the body of the jack. As shown, the jack comprises vertical channel members 1 secured to a base 2 and spaced apart to form slot-like openings 4 through which project extensions 6, 7 of the bracket 5. The extension 6 carries a lifting member 8, and anti-friction rollers 9, 10 carried by the bolts 11, 12 on the extensions travel on the members 1. The lifting screw 16 passes freely through the bracket 5 and is suspended from the top of the members 1 in an anti-friction thrust bearing 20. The screw is formed at its upper end 27 to receive a spanner and at the lower end of the screw is a recess 26 engaged by a pin 24 on a foot member 25 secured to the base 2. The nut 21 has abutments 22 moving in the slots 4, and the upper face of the nut is spherical or rounded at 23 to accommodate a similar face on the bracket 5. Lifting handles 28 may be provided. In a modification, the base houses bevel gearing by which the screw 16 is actuated.

Filed: 1938-10-20
Abstract: 518,153. Batteries. UNITED STATES RUBBER PRODUCTS, INC. Oct. 20, 1938, No. 30374. Convention date, Oct. 21, 1937. Drawings to Specification. [Class 53] A battery plate comprises a pasted grid and a paste - retaining covering of perforated vulcanized hard rubber composition which has been moulded or shaped after vulcanization so as to conform closely to any surface irregularities in the grid. The plate may have slots dividing it into columns, separate coverings of channel section surrounding each column, Figs. 7, 8, 9 (not shown), or the covering may comprise half envelopes secured to rubber strips inserted in the slots, Figs. 10 to 16 (not shown). The channel or tray-shaped coverings may be formed from perforated sheet vulcanized rubber by passing it successively through a heating chamber, between flanging rollers, under running water to cool it, between blunt cutting members, and finally to means for applying adhesive to the necessary parts, Figs. 1 and 2 (not shown). To secure the shaped coverings to the pasted grid, they are inserted in a bag of soft vulcanized rubber, which is exhausted, and then heated in a bath of liquid, thereby causing the covering to conform to surface irregularities in the grid and causing the adhesive to secure the parts of the covering together, Figs. 3-6 and 17-19 (not shown).

[Also in Division A2] Products such as milk in sealed containers of frangible or deformable material, e.g. bottles or cans, are heat sterilized while enclosed in a capsule. The capsule, Fig. 4, comprises a cartridge 34 which telescopes over a jar J and within a carrier 36. Dimples 90 prevent the cap of the jar J from contacting the end 86 of the cartridge 34. Both the cartridge 34 and the carrier 36 are formed of magnetically attractable material such as steel, and the carrier 36 carries a disc 100 of non-magnetic material secured to its end plate 96. In another embodiment (Fig. 6, not shown) the cartridge 34a is constructed of a plastics material, its end plate (106) being impregnated with a ferrous material. The filled and capped jars J are encapsulated in a capsule loader 32 (Fig. 1), and then fed successively through 5 heat treatment vessels of the reel-and-spiral type, twisted on a conveyer 50 to an upright position and then passed to a capsule unloader 52 where the two parts of the capsules are separated magnetically and returned to the capsule loader for reuse.

Abstract: 193,379. Ges. f³r Drõhtlose Telegraphie, and Bronk, O. von. Feb. 14, 1922, [Convention date]. Thermionic oscillalation generators. - A tuned circuit 5 in the output path of a thermionic generator is coupled through an intermediate circuit 6 to the circuit of the filament 3. Owing to the back-coupling, the electron stream from the filament is controlled in rhythm with the oscillations. occurring in the circuit 5. Preferably the two electrodes have large surfaces and are arranged close to each other, and the cathode 3 is formed of a coiled wire having as small heat-capacity as possible. In this way a two-electrode valve will function as an oscillation generator. If a third electrode, or grid, is employed, the backcoupling from the circuit 5 is linked with both grid and filament.

Title: Improvements in and relating to the production of regenerated cellulose filaments from viscose
Inventor: LEWIS PETER
IPC: D01F2/06
Filed: 1960-09-07
Abstract: Ribbon filaments of regenerated cellulose are made by extruding viscose having a cellulose to caustic soda ratio of at least 1 and at a salt point of 4-6 through a multihole jet, the holes of which have no re-entrant sector in their cross-sections, into a coagulating bath held at 40 DEG -60 DEG C. and containing at least 24% Na2SO4, 9-12% H2SO4 and not more than 0,02% ZnSO4 as an impurity, drawing the incompletely regenerated filaments from the bath and subsequently completely regenerating the filaments.  Preferably the jet holes are of circular cross-section.  The cellulose to caustic soda ratio of the viscose may be at least 1,4 with a salt point of 4-6, or may be between 1 and 1,25, when the salt point is desirably 4-4,5. In an example a viscose is extruded through holes of 0,005 inch diameter and the filaments pass through the bath for 24 inches before being lapped on a godet.  They are then stretched 30% in passing to a second godet of higher peripheral speed, collected in a centrifugal box and the cake washed successively with dilute acid and water. Such filaments have an elongated cross-section, their width being in general five times their thickness.
