Abstract: 861,357. Magnetic tests. ASKANIA-WERKE A.G. Aug. 25, 1958 [Aug. 23, 1957], No. 27214/58. Class 37. A magnetometer of the type comprising a magnet system mounted between torsion elements is provided with a scale for measuring the torque applied to the torsion head and a further scale for calibrating the instrument which indi-  cates when the magnet has rotated through two precisely known angles. As shown, the magnet 1, the upper face of which is silvered, is mounted by threads 2, 21 in a " U "-shaped bracket 3. The bracket is rotatable by a worm mechanism 7. 8 and its angular position is indicated by the projection of a scale 6 attached to it on a fixed scale 32 at the top of the instrument. At the same time light reflected from the magnet is imaged on to a further scale 34 carrying two pairs of accurately positioned marks 37, 38 and a central pair 35 which serve to indicate when the magnet is level. The instrument is provided with coarse and fine levelling adjustments.

[Also in Division B4]  A stapling machine for sealing the mouth of filled bags comprises a number of stapling tools 6, each having an operating lever 12 and mounted on a head 5 so that their jaws 10, 11 are directed downwardly and aligned so as to be capable of receiving an upwardly-presented closed mouth of the bag, the mouth being secured by inserting a row of staples upon the actuation of a common lever 24 coupled by means 13, 14, 15 to the several operating levers. The separate stapling tools are mounted on a frame 7 adjustably secured to a column 22, the operating levers 12, each being connected to a rod 13 having a pair of rollers 14 mounted thereon. The actuating lever 24 is in the form of a foot pedal pivoted at 26 attached by an adjustable rod 30 to a pair of cams 15 slidable in guides 16; the cams are urged by a spring 33 to the inoperative position shown in Fig. 1.

Abstract: 797,264. Radiation apparatus. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Sept. 7, 1956 [Sept. 10, 1955], No. 27461/56. Class 98(1) In a device containing a radio-active source of radiation, a channel in a lead screen is filled with mercury to prevent passage of rays, and a displacer operates by compressed air 'forces the mercury against action of a resilient member into a chamber adjacent to the channel. As shown, the radiation source 1 is enclosed by a lead sphere 2 having a mercury-filled channel 4 lined by a narrowed portion 3a of a steel tube 3. An inner wall 11 is connected at its outer end to tube 3, and an annular piston 8 and a spring 9 are housed in the space 12. A piston 5 is slidable in sealing rings 7 mounted in the tube 3. The outer end of tube 3 is closed by a member 6 having a channel 10 through which compressed air is admitted to force piston 5 inwards, displacing the mercury from channel 4 into the space 12, and compressing spring 9 by means of the annular piston 8. Since the piston 5 and member 6 are of naterial pervious to X-rays, rays may pass out of the sphere 2. On release of the pressure of compressed air, spring 9 and piston 8 force the mercury back into the channel 4, closing it against the passage of radiation.

In order to ensure the melting of a fuse element at a certain point, an incision 14 of small width is made and a solder deposit 18 applied on the part 15 of the element left by the incision, the solder forming an eutectic alloy of low-melting point with the metal of the fuse element when heated. The corners 16, 17 are bent back (Fig. 4) to prevent the formation of a current path across the incision, and they may be cut off. The incision may alternatively be a single cut (Fig. 3, not shown), or several cuts made from alternately opposite edges and each having a solder deposit (Fig. 6, not shown), or the incision may be oblique to the longitudinal axis. In another embodiment (Fig. 9) a trough 21 is formed in the element so that only the required quantity of solder is used. Arcquenching means are provided by a coating 22 of melamine, a urea resin, or other relatively carbon-free material. A particularly slow-acting element is shown in Fig. 11 where the melting point is protected against quick heat-loss by folds of the element. The eutectic alloy at the melting point may be formed before the element is used, either by direct heat or by passing a current through it.

Title: Improvements in or relating to the crimping and setting of textile strands
Inventor: IWNICKI KURT
IPC: D02G1/12
Filed: 1962-07-19
Abstract: 964, 909. Crimping fibres and yarns. BRITISH NYLON SPINNERS Ltd. June 17, 1963 [July 19, 1962], No. 27713/62. Heading D1F. In a process for crimping textile strands, e.g. polyacrylonitrile, polyamide, polyester, polypropylene yarns or tows, in a stuffer-box, the back pressure exerted on a strand at the successive instants of crimping is maintained constant by a continuous and automatic control thereof effective at a point between the crimping point and the point (generally at or near the discharge point) of initiation of pressure on the strand within the stuffer-box. The compression chamber may be divided to form crimping and setting zone endportions which are relatively movable over a limited distance to effect the control (see also Specification 964,910). As shown, yarns Y converged at a guide 9 are fed around a loaded roller 11 into nip rolls 1, 2, driven at an adjustable constant speed from endless belts 3, 4, through pulleys 5, 6, and gear-box 7. Rolls 1, 2, form the entry to the crimping portion which is also bounded by walls 17, 19, and 21, 22, with extensions 23, 24, leading into the mouth of the setting portion comprising a chamber 25 enclosed by a heater jacket 27. This portion is urged towards contact with the crimping portion by a weight 31 and is mounted on flexible arms 28 and 29 which permit limited movement sufficient to control correctively the pressure on the yarn within the crimping portion i.e. at the point where the yarn is discharged from the nip of rolls 1, 2. The temperature e.g. 140‹C.-180‹C., in chamber 25 may be maintained by electrical resistance heaters 41, 42, and the crimp is set by dry or wet heat. The back pressure within the stuffer-box is initiated by restriction e.g. a hinged, adjustable flap 37 or converging walls (not shown) at the discharge end of chamber 25 (but the cross-sectional area thereof need not be reduced) and crimped yarn is withdrawn around a pin 45. The limited movement of the setting portion may be utilized to activate means (not shown) for varying the rate or amount of feed or withdrawal of yarn &c. to or from the stuffer-box so that the amount of yarn therein is maintained constant: thus, the arms 28, 29, may operate microswitches which energize a tensioning device to regulate the tension in the discharged yarn.

Abstract: 1,179,890. Disc brakes; brake cylinders. ALFRED TEVES G.m.b.H. 15 June, 1967 [24 Sept., 1966], No. 27714/67. Headings F2E and F2F. A disc brake has a main actuating member operated when fluid pressure exceeds a given value, the initial pressure causing auxiliary piston-operated screw arrangements to advance the pad to the disc. In Fig. 1 the main brake is applied by pistons 6, 6a under fluid pressure in cavities 14, 14a, a valve (not shown), allowing the pressure to act only when it exceeds a given value. Prior to this, small pistons (Fig. 2) advance racks 7 to the right in (Fig. 2) to rotate rods 10 and thus the respective threaded members 8, 8a to advance members 9, thus to take up any slack. Movements of the rack also advances a friction held non-return member 17 (Fig. 2), springs 16 causing small clearance retractions of the pads when fluid pressure is released. Figs. 3 and 4 (not shown), utilize a similar piston-operated slack adjuster but the main brake pressure is applied by an eccentric cam acting on the end of one rack, the eccentric being revolved by a lever (21) operated by fluid pressure cylinder (not shown). The brake may be either of the moving caliper or moving disc type. In Fig. 6 slack adjustment is effected by a similar fluid pressure operated rack and pinion system. The piston 6 in the main cylinder is, however, held retracted by a stack of conical spring washers (22) so that it does not come into operation until the fluid pressure exceeds the spring pressure and slack adjustment has, therefore, been effected. Mechanical operation of the brake may be effected by an eccentric shaftportion 20 operating on the piston and rotated by a lever 21. In a dual braking system the front brake auxiliary cylinders are connected with the master cylinder for operating the rear brakes.
