Title: Improvements in edging machines for timber
IPC: B27B31/06
Filed: 1925-08-17
Abstract: 257,095. S÷rensen, E. F. Aug. 17, 1925. Addition to 239,892, Feed motions.-In an edge-trimming machine for timber using gauge pins as in the parent Specification, the gauge pins 1<a>, 1<b> actuate two or more independent means for limiting lateral displacement of the timber, being arranged in several independent groups, two in the modification described, so that the timber may be adjusted partly by translation and partly by rotation. For this purpose each group includes one pin 33 longer than the others and formed with a number of grooves 34, adapted to be engaged by pivoted blades 36 pressed by leaf springs 39 and operated by a cord 41 which is pulled by the action of pivoted plates 46<a>, 46<b> when the same are allowed to move under the pressure of a spring 48, which action occurs when all the pins 1<a>, 1<b> in the particular group have moved far enough to clear the edges of the plates. The upper and lower plates 46<a>, 46<b> are connected by a cord 45 so as always to move together, and may both be drawn outwards by means of a pedal-operated link 50 engaging a hook on the lower plate. During the adjustment of the timber it is held from moving forwaed with the feed chain by a spring roller (not shown) at its front end, and immediately after the adjustment a set of rollers 22 carried on pivoted 'brackets are pressed on the timber by the action of a cam 52, so as to. hold the timber during the withdrawal of the gauge pins, which is effected by cams 58, 63, the first of which operates the link 50 to withdraw the plates 46a, 46<b> and the blades 36, whilst the second actuates a slide 60 to withdraw the gauge pins. In a modified device illustrated m Fig. 8, pivoted feelers 2 are used, of the kind described in Specification 245,310, each acting to displace a wedge stop 4, so that a fence 6, which carries co-acting wedges 14, and is advanced by means of an eccentric 16, is checked by engaging the stop which has been furthest displaced, and then rotates about this point of contact, the motion being communicated to the work by the action of rollers 22.

Title: Packaging cheese
Inventor: COFFEY FRANK OATTS
IPC: B65B25/06
Filed: 1960-06-13
Abstract: In packaging a unit of natural cheese which is in condition to exude carbon dioxide, the unit is wrapped and sealed in a flexible film of moisture proof, gas-impervious material and there is provided in the sealed unit at atmospheric pressure a gaseous atmosphere of carbon dioxide and nitrogen in a ratio such as to prevent puffing of the package and to limit collapsing of the package, i.e. to prevent exudation of carbon dioxide from the unit and to limit absorption of carbon dioxide by the unit, the amount of carbon dioxide in the said atmosphere being directly proportional to the amount of carbon dioxide dissolved in the unit.  A natural cheese is one which has not, unlike a processed cheese, been subjected to heating at a temperature sufficiently high to drive off carbon dioxide.  Suitable wrapping films are of polyvinyl chloride, polyvinyl chloride laminated with polyethylene, polyvinyl chloride, polyvinyl acetate and copolymers of vinyl chloride and vinyl acetate.  Ordinarily, Swiss cheese requires a 50-80 volume per cent of carbon dioxide in the carbon dioxide-nitrogen mixture, Cheddar cheese a 25-70 volume per cent of carbon dioxide, and Brick cheese a 40-70 volume per cent of carbon dioxide.

Title: Improvements in or relating to the twisting and crimping of textile filaments
Inventor: RUSSELL JOHN PERCIVAL
IPC: D02G1/02
Filed: 1955-07-19
Abstract: 797,051. Spinning and crimping yarns; twist tubes. BRITISH NYLON SPINNERS Ltd. June 22, 1956 [July 19, 1955], No 20802/55..Classes 120(2) and 120(3) A device for imparting a plurality of turns of false-twist to a monofilament multifilament, or staple fibre yarn for each revolution of a rotatable part thereof, as may be required in crimping the yarn, comprises at least one rotatable member, e.g. a driven twist-tube. The member has a continuous bore, of circular crosssection and coaxial with the axis of rotation of the member, the surface of which comprises, at least at or around one endportion thereof, a non-abrasive material e.g. rubber with carbon black filler, having a high coefficient of friction with the yarn to be twisted by contact therewith on the path through the device: the least diameter of any bore exceeds the diameter of the largest yarn to be twisted and the shape and location of the material is such that the yarn is in contact therewith when the path of the yarn between entering and leaving the device is turned through an angle of at least 90 degrees. The tube shown in Fig. 1 comprises an annular portion 3 mounted on bearings 5, 7, within a fixed annular portion 1, rotated by a band 9 and carrying a rubber bush or insert 11 the full length of the inner surface and curved end portions of which engage a yarn 13. In a process for crimping yarn (or rendering it twist-lively) the yarn of thermoplastic material, e.g. synthetic linear polymeric amides or esters such as nylon or polyethylene terephthalate, cellulose acetate and triacetate, or non-thermoplastic filaments which have been treated with a thermosetting agent, passes around the drum of a magnetic hysteresis tensioner 19 which imposes a constant output tension on the yarn, through an infra-red heating device 21 comprising a glass tube 23 having electric resistance coils 25 wound thereon, through an air path constituting a cooling zone, through a twist tube 27 so mounted that the yarn makes contact with one side 29 of the rubber bush therewithin, over a pulley-wheel 31, and through feed rolls 33, 35, which forward the yarn at a slightly greater speed than that at which it is wound on a package 39. Heating of the yarn may be effected electrically by contact or radiation, by steam under pressure or by contact with heated solid particles, such as glass, in "fluidized" condition produced by passage of air therethrough. False twist of differing senses may be imparted to filaments, i.e. one or some filaments passing through the tube in one direction and one or some filaments in the other direction, and oppositely initiallytwisted filaments may be plied to produce balanced yarns. The yarn may be crimped by passage through two successive and contra-rotating twist tubes.

Title: Improvements in fuzes for aerial bombs, shells and other explosive projectiles and missiles
IPC: F42C15/295
Filed: 1943-12-13
Abstract: 576,664. Fuzes for bombs and shells. MIDGLEY, A. H. Dec. 13, 1943, No. 20846. [Class 9 (i)] Two percussion fuzes are described, one (Fig. 1) acting with delay and the other (Fig. 2) acting without delay. In both, the striker m (or electric-contact member) has a conical enlargement m<1> pressed by the spring o onto a ball or balls n, the lateral escape of which, to release the striker, is normally prevented by the enlarged lower end l<2> of a sleeve, the smaller-diameter upper part l<1> of which houses the spring o. In the bomb tail-fuze shown in Fig. 1, the sleeve is locked to a second sleeve k by a ball q and by a lead wire p. The ball q is anchored by a third sleeve e. This sleeve is supported by a deformable member h and carries an air-vane g which unscrews during the descent of the bomb so that, on impact, the sleeve e can move downwards by momentum and align an aperture e<2> with the ball q. Return of the sleeve e is prevented by a coiled-spring detent i. Sleeves l<1>, k remain connected by the lead wire, but the pressure of the spring o causes the wire to be slowly sheared, whereupon the spring lifts the sleeve and frees the balls n so that the striker can operate. The fuze-body comprises two slidably-connected parts a, b, locked against separation by a ball c which is released when an aperture e<3> in the sleeve e is, aligned with it on impact. Thereafter, if an attempt be made to unscrew and remove the fuze before the lead wire is sheared, the spring o will raise the two sleeves k, l<1> as the body-parts a, b are moved apart, the balls n will be released, and the striker will act. The momentum sleeve e is made of hardened steel to defeat any attempt to drill into the fuze. In the fuze of Fig. 2, the striker-spring sleeve l<1> is locked by an unstably-supported ball r<1> normally held in position by a sleeve r which is urged upwardly by a spring r<2>. Movement of the sleeve is prevented by a finger r<5> which bears against the air-vane nut g. Unscrewing of the nut allows the sleeve r to lift and free the ball r<1>, which is unseated on impact to permit the fuze to act instantaneously.

Abstract: 991,714. Removing residues from filters. BABCOCK & WILCOX Ltd. May 31, 1962 [May 31, 1961], No. 21015/62. Headings B1D and B1T. [Also in Division G6] To facilitate the handling of matter containing radio-active particles filtered from a fluid circuit, a liquid is solidified so as to immobilize the matter and retain the particles in position whilst said matter together with the solidified liquid is removed from the circuit. The Figure shows an apparatus suitable for filtering the carbon dioxide coolant of a gas-cooled nuclear reactor. The gas enters filter chamber 1 through a valve 3, and passes over candle filter 2 which removes the corrosion products and dust particles. The particles so filtered collect in a removable vessel 5 above which there is a tube 6 connected to a supply of liquid CO 2 . Connections 7 and 8 are joined to means (not shown) for enabling the pressure in chamber 1 to be be lowered. To remove 5, valves 3 and 4 are closed, the gas pressure in 1 is reduced by cooling and by inlet 7 to four or five atmospheres when liquid CO 2  is introduced through line 6 and on further pressure reduction ices over and solidifies, whereupon vessel 5 can be easily removed avoiding the escape of any fine dust particles. In a water cooled nuclear reactor, the water coolant may be frozen on the filter, and the filter and unwanted matter fixed thereon conveniently removed.
