Title: Improvements in or relating to the wings, supporting planes, or other surfaces, and automatic stabilizing devices for aircraft
IPC: B64C13/00
Filed: 1928-03-05
Abstract: 313,065. Peters, P. N. G. March 5, 1928. Steering and balancing. - A wing. tail plane or fin of an aircraft is provided with a freely pivoted pilot plane, in front of the leading edge, interconnected to an aileron, flap, elevator cr rudder so as to move control surface automatically as the air currents change, or assist the pilot in effecting manual control, the interconnection being such that the trailing edge of the pilot plane and the. trailing edge of the corresponding rear flap move in the same direction. In the case of ailerons, each aileron may be divided and a part remain under the control of the pilot, but means for interlocking the two sections may be provided. Fig. 1 shows a pilot plane 2 pivoted at 3 and connected by a tube 6. adjustable in length, to an aileron so as to move the aileron in the same sense as the. pilot plane moves. Provision may be made for enabling the pilot to actuate the ailerons for balancing without interfering with the automatic. actuation. Fig. 6 shows such an adjustable tube, one end being connected to a piston 16 having cup leathers 18 working in a cylinder having a byepass tube 9 provided with a cock 10. The cylinder is filled with air or liquid, and the tube is adjusted to the right length when the cock 10 is open, after which the cock is closed. This tube 6 in the case of a rudder may be varied in length by the pilot to vary the rudder setting. Electric means may be applied to the pilot plane to indicate the approach to a stalling position or to record its movements. Specification 289,517 is referred to.

Title: Improvements in or relating to the binding of skins or the like
IPC: C14B1/00
Filed: 1935-03-04
Abstract: 457,758. Wire-stitching. PANNONIA BARANYBORNEMESITO ES KERESKEDELMI RESZVENYTARSASAG, Ujpest, and BARTHA, A., 39, Peterdy Utca, Budapest, both in Hungary. March 4, 1935, No. 6822. Convention date, March 3, 1934. [Class 89 (iii)] [See also Groups XVII, VIII, and XV] Skins, leather, and other sheets are fastened together by passing two or more needles through a pile and withdrawing them with a wire or thread through the holes thus formed, the ends of the wire being twisted to secure the bundle. A leather, metal or wood covering sheet may be automatically applied to the top and bottom of the pile during the operation. The skins 3, Fig. 1, to be bundled are placed on a table 2 and a wire 10, Fig. 3, is fed below the table by being drawn from a reel 8 by jaws 19, 21 over a guiding roller 9. The jaw 19 is opened by a stop 20 on approaching the free end of the wire, and rides over it on the return movement, depressing it against the action of a spring. The stretched wire is pushed forward by a roller on a cam-actuated rod 25, so as when released to be caught by the needles 31, which have hitherto remained in the upper inoperative position. The needles, which are mounted on a piston 44, now descend, guided by a sleeve 32 which is also lowered until the plate 60 rests on the top of the pile of skins. The needles are moved further downwards and on arrival at their lowermost position, the rod 25 is retracted to allow the wire to engage the needles. When the needles commence to rise, the wire is caught by hooks thereon and carried up through the holes made in the skins as shown in Fig. 7. The end of the wire gripped by the jaws 19, 21 is freed by the action of another stop 20<1> and the run of the wire is cut by an edge on a rod 55. The ends 61 of the wires, Fig. 7, are drawn completely through the pile of skins and project upwards into the casing 32, which is then rotated by a belt and pulley to twist the ends. Layers of covering paper, leather, &c. are fed in continuous sheet form into position at the top and bottom of the pile where they are pierced by the descending needles. The upper layer is cut from a strip 36, Fig. 4, fed into position by rolls 67, 68 passing over a ring 37 and beneath circular shears 38 supported by a coiled spring upon a sleeve also spring-supported. A lever 28 depresses the shears and sleeve in succession prior to the descent of the needles, and while the needles are penetrating the strip the lever is further actuated to cut out the covering blank which is then carried down on to the pile. Suitable mechanism effects the feed of the strip after the needles have risen again and similar operations take place below the pile in order to apply a bottom cover. Three or more needles may be used, string or metal strip may replace the wire, the ends may be sealed or made to adhere after twisting and drills in place of needles may be employed.

Title: Improvements in or relating to coin testing mechanism for use in coin-freed automatic machines
Filed: 1932-03-07
Abstract: 398,188. Coin-freed apparatus. LUCAS, T. S. and FRETWELL, C. M., 5, Wine Office Court, London. March 7, 1932. No. 6838. [Class 27.] Testing coins.-Mechanism for preventing the actuation of coin-freed apparatus by a coin without a milled edge comprises a toothed member 21 located adjacent to an aperture 17 in one edge of a coin shoot 13 and secured to a weighted or spring-controlled arm 24 carrying a detent 26 which projects through a lower aperture 27 in the shoot. The coin 31 is caused to press against the teeth 22 of the member 21 by a knife edge 18, and if it has a milled edge it will engage the teeth and swing the arm 24 about its pivot 19, thus withdrawing the detent 26 from the shoot and allowing the coin to fall into the portion 14 thereof ; if, however, the coin has a smooth edge it will slide past the teeth and compress a spring 23 mounted within a slot 20 in the member 21 through which the pivot 19 passes, the detent being left in the shoot and deflecting the coin into a lateral return shoot 15. Coin action, with stationary coin forming abutment.-The shoot 14 may lead to independent coin-actuated mechanism, but as shown the coin action is combined with the testing mechanism. The pivot 19 of the arm 24 is mounted on a hand-operated slide 11 which may at all times be raised to an extent limited by the engagement of the detent 26 with the upper end of the slot 27. An inserted coin falls past a one-way catch 29, and if the slide 11 is now raised, the teeth 22 of the member 21 will be forced against the coin 31 and will engage the milled edge thereof to swing the arm 24 outwardly as described above, thereby freeing the detent 26 from the slot 27 and permitting the slide 11 to be raised to its full extent to actuate the machine. Means may be provided to prevent the insertion of a coin while the slide 11 is in the raised position.

Title: Method of reducing compressive stresses in radial arms of rotor spiders of electrical machines
IPC: H02K1/30
Filed: 1960-03-01
Abstract: 882,265. Core constructions. ALLMANNA SVENSKA ELEKTRISKA A.B. March 1, 1960 [March 3, 1959], No. 7174/60. Class 35. In an electrical machine in which a prestressed magnetic ring 5 is mounted on a rotor spider, compressive stresses in the spider radial arms 3 due to the pre-stressing are reduced by a method comprising so mounting the ring on a number of radially extending rods 4 arranged between the ring and a boss 2 that the rods absorb at least the main part of the stresses, the arms transmitting the torque prevailing between the ring 5 and the boss 2. The prestressing may be effected by shrinking the ring 5, by elongating the rods when made of two screwed-together parts, or by wedges. The rods, which may be of steel, bronze or aluminium, may be guided by one or more plates 7, and the arms and rods may be either at right angles to or as shown inclined to the spider axis.

Title: Improvements in or relating to low temperature polymerisation process
Inventor: HOWE RALPH FINCH
IPC: C08F210/12
Filed: 1952-03-20
Abstract: In a continuous process for the low temperature copolymerization of isobutylene and a multi-olefine, the reactor is solvent-cleaned and cooled to -6 DEG  to -164 DEG C. and is fed with a mixture containing, relative to the normal feed, a greater proportion of diluent and butene-1 and a smaller proportion of isobutylene and multi-olefine, and a Friedel-Crafts catalyst, until polymerization begins, when the feed is gradually changed to the normal mixture. The multi-olefines preferably have 4 to 14 carbon atoms and specified are isoprene, butadiene, dimethyl butadiene, 2-methyl-, and 3-nonyl-butadiene-1, 3 and myrcene.  The specified diluent is methyl chloride.  The initial feed is preferably made up by passing into the reactor the normal diluent, isobutylene consisting mainly of recycle isobutylene and containing a higher proportion of butenes as impurities, a small amount of recycle or fresh multi-olefine, and butene-1 obtained from the purification plant.  When the reactor is full, the catalyst stream is begun and polymerization begins when the catalyst concentration is sufficiently high.  Generally, the normal feed is begun when the catalyst stream starts, with a gradual changeover until normal polymerization begins.  The process reduces runaway reactions and the production of unsatisfactory polymers after a reactor is cleaned.

Abstract: 1371104 Ion sources APPLIED RESEARCH LABORATORIES Ltd 20 March 1972 [19 March 1971 1 July 1971 10 Sept 1971] 7304/71 30794/71 and 42253/71 Heading H1D In the analysis of a material by a mass analyser, a gaseous medium containing ions of the material is produced by injecting the material in vapour, liquid, or aerosal form, into a high temperature plasma which is at atmospheric pressure, whereafter the gaseous medium containing the ions is fed to the mass analyser through a pressure reducing stage. The high temperature plasma is produced in an argon or helium carrier gas by an r.f. electrodeless discharge, or by a D.C. discharge in gas flowing through a capillary tube. For a massive solid example either an aerosol suitable for injection into the plasma is produced by employing the sample as the cathode for a D.C. arc struck in flowing argon or helium, first compressing a powder mixture of the material with graphite or metal into a solid cathode if the material is an insulator; or a pulsed laser beam is focused on to the sample surface in flowing gas, the sample being moved between successive pulses to vary the point of impact. The plasma containing the ionized material is sampled by extracting a portion through a fine orifice and passing the resulting beam through a succession of low pressure regions. If greater control of ionization is required, ions are removed from the beam by a transverse electric field, and the resulting neutral beam is passed into an electron impact ionizer. As shown in Fig. 1, a D.C. discharge is maintained between the anode 11 and the sample cathode 10, the carrier gas entering at tube 13 and carrying the sample particles into a high temperature plasma formed in the capillary tube 18 by a discharge between electrodes 16 and 17. Most of the plasma passes out through the pumping tube 20, the remainder being drawn off through a fine orifice 21 into the mass analyser entry tube 22, which is maintained at reduced pressure by the pumping tube 23. The apparatus of Fig. 4, in which the plasma is produced by electrodeless discharge in a capillary tube 32 mounted in a microwave cavity 33, is suitable for sample material which must be maintained within a given temperature range: the sample aerosol, e.g. from a chemical reaction and at 300 C. is expanded into the pipe 35 at a point of the plasma tail at which it has cooled to that temperature, whereafter a portion is drawn off to the mass analyser 41, thermal lagging 39 preventing further substantial reduction in temperature.
