Title: A container
IPC: B65D3/00
Filed: 1960-10-27
Abstract: 900,439. Making tubes. CONTAINER CORPORATION OF AMERICA. Oct. 27, 1960 [Nov. 9, 1959], No. 36887/60. Class 99(2). [Also in Group XVII]. A container 10 is formed by spirally winding an inner ply 11 of fibrous material having its adjacent edges butt-jointed and an outer ply 13 of fibrous material bonded in its outer side to a label 15 and on its inner side to the inner ply 11 except where the ply 11 is masked by a tear strip 14 covering the butt-joint, the container being opened by pulling a lift tab 28 formed in the label 15, outer ply 13 and strip 14, which exposes the butt-joint of the inner ply along a spiral strip. Score lines 44 are cut in the outer ply 13 either side of the buttjoint of the inner play 11; and the tab 28 is formed by a periodic cut made through the label 15, the outer ply 13 and the strip 14 across the width of the space between the score lines 44. A layer 12 of paper-backed foil is adhered to the inner face of the inner ply 11 which may be of chipboard. The outer ply 13 is of Kraft paper. The container may be used to contain biscuit dough which generates pressure by leavening action so that, on tearing off the strip 14, the pressure will rupture the liner 12 and split open the container body. Making. The container is formed on a mandrel 16 of a spiral winder apparatus SW. The tube so formed is fed along the mandrel by a friction belt B and is cut out to size to form individual container bodies to which end closures 17, 18 may be seamed.

[Also in Division E2] A resilient fastener for holding a threaded screw in an apertured panel, comprises a tubular shank 11, Fig. 7 (not shown), having external longitudinal ribs 15 and 16, Fig. 1 (not shown), for insertion in the aperture, Fig. 6 (not shown), so as to be non-rotatable therein, a resilient dished flange 12 at one end to seat on the surface of the panel, and groove 13 in the external wall of the shank adjacent the flange to receive the rim of the aperture. The fastener includes a bore of equal diameter to the root of the thread of the screw, so that upon insertion the screw cuts a thread in the bore of the fastener. The bore has longitudinal grooves 17 and 18 so that the shank can be collapsed when passed through the aperture. The bore may be stepped, the greater diameter being at the flanged end. The flange may be square-shaped. The dished flange allows an angular movement of the screw within an imaginary cone having its axis coincident with the centre of the aperture and an apex angle of 30 degrees.

Filed: 1946-12-14
Abstract: 619,593. Reeling yarn. EWART & SON, Ltd., W., and McEVOY, W. E. Dec. 14, 1946, No. 36935. [Classes 120(ii) and 120(iii)] A yarn reeling machine of the kind in which a series of hanks, each of predetermined length, are reeled on to. a swift B from a corresponding number of bobbins A, is provided with a stop motion which acts as a controller for the whole machine and is brought into operation upon breakage or exhaustion of an end of yarn, each yarn supporting a small faller D which engages a reciprocating bar C and causes it to become stationary thereby stopping the oscillation of a member E connected thereto, so that a rod H slidably mounted in the member E will be actuated by a cam G to operate a switch K in the circuit of the motor M1 driving the reel to stop the motor and at the same time to release a spring-urged brake R which is then applied to a gear wheel Rl in the reduction train between the motor Ml and the reel shaft to stop the same. The rod H in actuating the switch K through a lever J, also, through a wire t removes a catch T to allow the spring r to apply the brake R. The brake R may be released from the wheel Rl through linkage V, V1, V2, V3, the rod V extending across the machine, or by a foot pedal U. The rod V also operates a starting switch W. When the predetermined length of yarn has been wound a dog L on a vertical bell shaft l, driven through gearing from the swift shaft, trips a hammer M which strikes a catch N to raise a projection Q thereon to allow a yoke-shaped spring-urged plunger P to move forward into the path of the rod H, so that the cam G will again stop the machine by moving the rod H and so operating the motor switch K.

Inventor: KRAFT PAUL
IPC: B01J35/06
Filed: 1962-10-01
Abstract: A porous metallic article is made by coating metal fibres with a metallic alloying constituent, diffusion annealing to homogenize the material and finally compacting to the required shape. The coating may be applied from the vapour phase, by hot dipping, electroless deposition, by the hydrogen reduction of metal salt solutions.  Gas plating of steel wool fibres with chromium is carried out at 1000-1100  DEG C. for 2-3 hours with annealing at 1100-1400  DEG C. for 1/2 -3 hours.  Nickel or aluminium may also be used as coating materials.  The following specific examples are given: (1) steel wool chromized in a halogen atmosphere with diffusion and annealing at 1150-1180  DEG C.; (2) steel wool aluminized at 600/660  DEG C. in nitrogen with a suspension of aluminium powder in alcohol; (3) steel wool coated with nickel by immersion in nickel nitrate, and heating at 1200-1400  DEG C.ALSO:Steel wool homogenized and diffusion treated with chromium (see Division C7) is wound on a roller which has an angle iron frame and after being covered with a linen or felt cloth is used in ironing machines and wringing apparatus.  The resulting roller is permeable to steam which may be fed to its interior.

Hypostasis reactions are automatically recorded on photo-sensitive paper 5 by illuminating from a light source 1 a specimen of blood contained in a sedimentation tube 3 through a first diaphragm 2 and allowing light which passes through the particle free column of liquid to pass through a second diaphragm 4 to be incident upon the photosensitive paper, wherein relative movement between the second diaphragm and the paper is effect in a transverse direction and the light source is switched on and off automatically at spaced intervals of time to provide a plurality of recording spaced in a transverse direction on the paper. The paper issues from a roll 7 and is held in a guide 6 attached to a suspension 8 which is pivoted about a shaft 9. A slider 16 attached to guide 6 bears against a cam disc 14 which together with a graduated drum 13 and a feed wheel 12 is rotated by a motor 10 via a slipping clutch 11, the cam disc rotating once every two hours. A lug 20 secured to drum 13 actuates a switch 21 in the motor circuit and cam portions 19 on drum 13 actuate a switch 18 in the lamp circuit. In operations, the sedimentation tube is adjusted so that the top of the blood column is against a datum point, e.g. the top of the second diaphragm, and the apparatus switched by rotation of feed wheel 12. An initial exposure is made, and subsequent exposures made after one hour and two hours. A plurality of portions 19 may be provided on drum 13 to produce a number of recordings from which a curve can be drawn to represent the hypostasis per unit time.

[Class 100 (ii).] Addressing and like machines; copying documents.-In a statistical machine for the production on fresh record cards or strips of the written matter carried by statistical record cards or strips, the printing is made at will from desired sections only of the successive statistical cards or strips. Each statistical card, which is perforated according to the Tauschek system, has on it written matter which is also carried, but reversed, on the reverse side of the card, this being obtained by the use of hectographic carbon paper at the back of the card when the matter is being typed on the front. After a card has passed from the magazine 1 and been read by the feelers 4 the back of the card is moistened by rollers 7, 8 from a liquid tank 8. Thereafter, a cam 16 passes a roller 10 down on to a roller 11 so that the hectographic ink prints the written matter on to a record strip 17. Rollers 10, 11 are mounted in slotted bearings, being raised to the top of their slots by springs. The slot for roller 10 is, however, larger than that for roller 11 so that normally these rollers, which are constantly rotated, do not engage one another to feed the strip 17 and the statistical. card. Autographic writing may be effected at table 19. By dividing the roller 10 into several parts 10a, 10b, 10c, Fig. 11, under the independent control of cams 16a, 16b, 16c written matter on different parts of the cards may be printed on independent record strips 17a, 17b, 17c. Preferably these cams 16a, 16b, 16c are clutched independently to shaft 27 for rotation, by clutches 26a, 26b, 26c actuated by magnets 25a, 25b, 25c and card brushes 28a, 28b, 28c.
