Abstract: 950,711. Starting magnetic disc records. SIEMENS & HALSKE A. G. July 9,1962 [July 7, 1961], No. 26359/62. Heading G5R. A fan 6, driven by a motor 3, is mounted concentrically about the drive shaft 7 of a foil disc 15 and provides air-cushioning between the foil and a guide plate 12 during starting and stopping. A stationary, adjustable member 14 defines a labyrinth 13a to regulate the Bernouilli pressure in the space 13b, produced by the disc rotating at its operative speed and hence the spacing of the disc from heads 16, 17. Lifting of the disc-edges by vortex effects due to the rotation of superambient air by the disc is prevented by a cover 18 with radial ribs 19, a cover-operated switch d requiring to be closed before the disc-driving motor 2 can be energized. The fan-motor has a centrifugal switch which also requires to be closed before the motor 2 can be energized while a relay system (Fig. 2 not shown) switches on the fan for 40 seconds when the motor 2 is switched off. The fan may also be operated, when the disc is staionary to raise it to facilatate loading and removal of the discs which are driven interchangeably by unspecified means 8. Preferably the apparatus is supported with the motor axes out of the vertical for convenient presentation towards an operator.

Title: Improvements in feed devices for stiff filaments
Inventor: RIGBEY LEONARD JOHN
IPC: B21C47/34
Filed: 1962-07-12
Abstract: 977,738. Feeding wire. INTERNATIONAL BUSINESS MACHINES CORPORATION. July 10, 1963 [July 12, 1962], No. 26892/62. Headings B3E and B3W. [Also in Division D1] A device for simultaneously feeding and rotating a wire or like stiff filament comprises two mutually aligned, reciprocable and rotatable feeders each of which includes balls which are urged by cam means into gripping contact with the wire when the feeder is moved in one direction. Two such gripper feeders are shown in Fig. 2 in alignment on a filament 18, each of the sleeves 8, 10, including a set of three balls 26, 28 housed respectively in truncated tapered recesses 34, 36 in the sleeves the balls being spring-urged towards the smaller ends of the recesses. Reciprocation of the feeder 10 causes intermittent feeding of the filament, the feeder 8 serving to prevent any tendency to reverse feeding. The feeding motion is combined with rotation of the filament if the two sleeves are rotated. Apparatus is shown in Fig. 1 in which the sleeve 10 may be reciprocated and both sleeves continuously rotated, the apparatus including a reel 6 of wire mounted in a support 3, 3a so as to be rotatable about its own axis, the support 3, 3a being itself rotatable on pedestals 4, 5 by means of a drive pulley 7. Wire from the reel passes through the sleeves 8, 10 which are mounted to rotate with the support 3a, the sleeve 10 being reciprocated by the mechanism 9, 11, 12, 13. The device is stated to have particular application in the assembly of magnetic cores, in which process thin wire has to be fed through small holes, the rotation of the wire while being fed serving to prevent the wire catching on any rough edges.

Abstract: 767,344. Melamine. AMERICAN CYANAMID CO. Sept. 17, 1954 [Sept. 18, 1953; Sept. 18, 1953; Sept. 18, 1953; Sept. 18, 1953; Sept. 18, 1953; Sept. 18, 1953], No. 26988/54. Addition to 718,934. Class 2 (3). [Also in Group III] Melamine, cyanamide and dicyandiamide are produced by heating urea or an intermediate thermal reaction product thereof to a temperature of at least 220‹ C. at atmospheric or superatmospheric pressure, preferably up to 750 p.s.i. in the presence of a catalyst consisting of an absorptive material having a surface area of 180-650 m<SP>2</SP>/gm. In the range 220-400‹ C., the product is mainly melamine. Above 400‹ C., the melamine begins to decompose to cyanamide and other products. Intermediate products specified are biuret, cyanuric acid, cyanic acid, ammelide, ammeline, melam, melem. A mixture of these may be produced by heating urea to 270‹ C. under pressure. Catalysts specified are silica, alumina, silicaalumina, titania, zirconia, and thoria gels, pumice, diatomite, infusorial earth, and clay and clay-like materials, e.g. kaolin, bentonite, bauxite, and fuller's earth. The clay and claylike material is preferably activated by pretreatment with silica. The catalysts may contain 2-20 per cent of water. The reaction product may be leached first with ether to remove cyanamide and then with hot water to remove melamine, which is precipitated on cooling, and the dicyandiamide recovered by evaporation of the remaining solution. Melamine may be continuously produced by passing urea or the like into the absorbent maintained at a temperature of 400‹ C. and subliming off the melamine produced in a current of ammonia at 400‹ C. The melamine may be condensed in a vessel maintained at 100‹ C. and the residual gas, consisting of ammonia and carbon dioxide, passed to an ammonium carbamate recovery unit. The melamine may be sublimed in the absence of a sweeping out gas. The absorbent may be fluidized, optionally in two or more stages. In a two-stage process the catalyst fluidized by means of ammonia is heated first at 220‹ C., ammonia and carbon dioxide being recovered, and then at 350‹ C. In a three-stage process, the catalyst is heated at 220‹ C. to form carbon dioxide, at 250‹ C. to form melamine without stripping it from the absorbent, and finally at 350-400‹ C. to strip the melamine formed.

A detachable change-giving mechanism for a coin-freed device comprises a rotor 5, Fig. 2, provided with compartments 8 which are loaded with change which is delivered upon actuation of the coin-freed device and consequent rotation of the rotor. A pivoted lever 1 of the coin freed device moves rightwards, to rotate an arm 18 having two pawls 30 which contact a ratchetwheel 31, Fig. 1, connected to the rotor shaft 20. The arm 18 steps the ratchet upon its return, thus bringing a next compartment 8 above an aperture 25 to deposit its coins into a shoot 26. The lever 1 is prevented from returning prematurely by a spring-loaded ratchet 34, Fig. 2. A catch 32 projects between arms 7 of the rotor to hold the rotor stationary and is moved clear of the rotor when the arm 18 is rotated. Alternatively, a similar catch may operate on the ratchet. To reload the mechanism it is detached from the coin freed device by disconnecting lugs 29, and a transparent plastics disc 12, Fig. 1, is unscrewed from the back.
