Patent GB-1349883-A (GB)
Title: Strip handling apparatus
IPC: G03B21/32
Filed: 1971-05-10
Abstract: 1349883 Tape apparatus EASTMAN KODAK CO 10 May 1971 [8 May 1970] 14043/71 Heading G5R In a strip, e.g. tape, handling apparatus which automatically feeds the strip from a supply single reel cartridge 10S past a read/write station 101 to a similar take up cartridge 10T, the strip is formed with apertures 21, 25 adjacent each end thereof and each cartridge is provided with a strip anchoring arrangement including a finger 11 and barb 12 which engage the aperture in the outer end of the strip. On switch on, solenoid 115 is operated via cartridge activated switch 110 and strip detector switch 111, turning arm 118 clockwise and moving the tape 23 off barb 12 in the supply cartridge 10S. At the same time part 120 of the solenoid armature 116 closes switch 121 energizing solenoid 122 so that roller 127 moves the end of the strip into engagement with driven roller 130 and the strip is drawn off finger 11 and moved into guide channel 135 where it is engaged and driven by rollers 137, 138. When the tape is detected by switch 111, solenoid 115 and hence solenoid 122 are de-energized, restoring arm 118 and roller 127 to their initial positions; additionally, threading mechanism 140 and hub diameter sensor 141 associated with take up cartridge 10T are energized. After being driven past the read/write station the tape opens switch 105 de-energizing solenoid 104 so that curved guide member 108 pivots clockwise out of the subsequent path of the strip adjacent finger 11 of the take up cartridge. After passing switch 105 the strip is additionally driven by rollers 143, 144 and actuates a strip sensing mechanism 147 which switches on the take up reel drive. The strip is then guided on to the take up reel hub by the threading mechanism 140 (not described) which is de-energized when the diameter sensing mechanism 141 determines that a number of convolutions have been formed on the reel. When the end of the strip leaves the supply cartridge, switch 111 returns to its initial position but re-activation of solenoids 115 and 122 is prevented by mechanism 149 which opens the circuit to solenoid 115 when the supply reel is empty. As the strip end passes switch 105 solenoid 104 is re-energized and curved guide 108 is moved anticlockwise to guide the aperture 26 adjacent the tape end over finger 11. The take up reel drive is switched off by the sensing mechanism 147 but the inertia in the reel is sufficient to move the aperture over the barb 12 to anchor the strip end.

Abstract: 586,553. Gas turbines. BAUMANN, K., and METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. Nov. 6, 1941, No. 14336. [Class 110 (iii)] The contra-rotational elements, 9, 10, Fig. 3, of an air-compressor .are driven by contrarotational turbine elements I, II radially outside the compressor. The number of turbine blade rings is less than the number of compressor blade rings. The compressor carries the turbine discs by means of cylindrical parts 13, 14. The air is delivered to a swan-neck combustion chamber and the turbine exhaust passes to an annular discharge 37 which, merges into a propulsion jet. Air is received by a forwardly directed entrance 39 and reaches the air-compressor by way of a number of pipes 40 of stream-line section which cross the discharge 37. Another ring of blades may be carried at the end of a cylindrical extension of the shrouding of the blade ring I and a further ring may be carried by a cylindrical extension of the foundation ring of the blades II. Two compressors may be arranged in series, each being driven by pairs of turbine blades, as shown in Fig. 3, in series. Three compressors may be arranged in series, adjacent compressor rotors being driven by contra-rotational turbine pairs with single turbine blade rings on the end compressor rotors co-operating with fixed guide rings. The turbine elements I. II, Fig. 3, may carry externally directed air blades. Specifications 586,551, 586,552 and 586,560 are referred to.

[Class 39 (ii).] An electric incandescent lamp is provided with an internal glower which is highly absorbent of heat rays and receives heat reflected from the walls of the. bulb. A portion only of the wall is permeable to light, the remainder of the bulb being made substantially reflective of all rays, while the part that is permeable to light is adapted to retain heat and to form a filter to pass only rays of short wave length. The filter may be arranged as a grating consisting of an accumulation of particles of precious metals, copper, nickel, iron, &c. The walls of the bulb may be frosted externally or internally, and a reflecting portion thereof may consist of a metallic coating obtained by thermal decomposition or chemical reduction of suitable materials. A glower for use in the lamp may be obtained by electrically heating a tungsten wire and passing it through a heat absorbing substance such as an oxide, carbide, nitride, &c. of a rare element. Preferably the metallic filter is protected by a thin coating of glass, water glass, &c.

The polymer may comprise polyethylene, e.g. of density greater than 0À94, or ethylene polymerized with a minor preparation of propylene, butylene, or hexene; acrylonitrile; polybutadiene; styrene (ABS) terpolymers; and toughened polystyrene. The plurality of extrudates preferably comprise six, and at least twelve; may be of round, square, oval or star-shaped section; are preferably of a length width: ratio of at least 2 : 1, e.g. 4 : 1; may differ in colour; and may comprise tubes having inner and outer surfaces of different materials, e.g. high arid low density polyethylene. The collector may form part of the article, e.g. if made of a thermoplastic polymer, or may be removable, e.g. if of cardboard, and may be sprayed with adhesive to improve adhesion to the extrudate. The collector may be stationary, or may be rocked or inclined when inverted as the extrudes cool, and the extrudates are preferably cooled whilst inverted to a degree that they do not flow upon return to an upright position.

Title: Improvements in heteropolar inductor alternators
IPC: H02K19/24
Filed: 1941-11-15
Abstract: 554,827. Inductor alternators. BRITISH THOMSON-HOUSTON CO., Ltd., and WALKER, J. H. Nov. 15, 1941, No. 14710. [Class 35] A heteropolar inductor alternator has each stator pole 11, Fig. 3, toothed as at 10, consecutive sets of teeth being displaced by one or an odd number of half tooth pitches relative to the uniformly toothed rotor 1, so as to provide alternate zones of high and low reluctance which interchange when the rotor moves through half a tooth pitch; the exciting winding 3 embraces two consecutive zones, and the high-frequency output winding 4 is wound in the remaining slots. In the simplest case, a six pole rotor co-operates with a four pole stator, the poles being untoothed. The slots carrying the exciting winding may be wider than the others, A number of independent rotors on the same shaft may rotate within a single stator field system, to generate a polyphase or multi-frequency supply. Specifications 3666/03, 8227/15, [both in Class 35], and 534,784 are referred to. According to the Provisional Specification the output winding may be wound round every single pole or alternate single poles. The exciting winding may give a 2, 4, 6 or 8-pole field and may embrace up to eight toothed poles. In the form shown in Fig. 6, the output winding 4 may surround alternate poles, except that the poles on either side of the exciting slot 6 are surrounded by a single coil or by no coil at all. The slots carrying both exciting and output coils may be deepened and wedges may separate the coils. In certain arrangements, fluctuations in the heteropolar field flux must be damped out by copper or brass wedges closing the slots and shortcircuited at each end by rings. The laminated pole pieces may be fastened inside a steel or cast iron stator by dovetailed keys or screws. Reference has been directed by the Comptroller to Specification 550,255.
