Title: Improvements relating to suspension filing devices
IPC: B42F15/00
Filed: 1960-11-16
Abstract: 934,562. Suspension filing systems. R. BRINKMANN TO BROXTEN. Nov. 16, 1960, No. 39390/60. Addition to 880,244. Class 146(1). A folder according to the parent Specification adapted to be suspended from a single supporting rail, is modified in that the attachment fitting 1 is provided with a projection 15 adapted to engage a side face of the rail 10 or to engage a correspondingly shaped groove 17 in the underside thereof. In this latter position, the folder is displaced laterally with respect to the other folders in the hanging registry to indicate, for example, that the contents of the folder have been borrowed. The edge 12 of the attachment fitting projects above the hanging edge 11 of the folder to prevent said edge 11 coming into contact with the underside of the rail 10. That part of the attachment fitting projecting above the hanging edge is thicker than the lower portion 2, there being steps in the thickness which engage the hanging edge of the folder. The base 8 of the hook is positioned substantially at the centre of said hanging edge.

As shown, Fig. 2-6, fibres F are carried by perforate conveyor 40 between transverse infrared heaters 63, 66 in oven 26, while ejectors 68, 68', receiving air pressurised at 1 kg/cm<SP>2</SP>G, maintain air curtains X 2 . The curtains are deflected by air from duct 71 into suction duct 73. Auxiliary longitudinal infrared heaters 67 are positioned above and below the fibres and on either side of the fibres. Each ejector, Fig. 5, comprises a tube 82 having nozzles 83 positioned to produce an even flow through slit 84. Each heater comprises a nidrome wire coil in a ceramic tube (Fig. 6. not shown). Heaters 66, 63 may be moved vertically. Alternatively (Fig. 7, not shown) the fibre runs between rollers located beyond the oven ends, the fibre being unsupported in the oven and being cooled by a transverse air jet downstream of the oven. The heating of acrylic fibres is exemplified. The air curtains are said to prevent overheating and yellowing of the fibres.

Abstract: 996,127. Amusement apparatus. DELUXE READING CORPORATION. Oct. 29, 1962 [Dec. 18, 1961], No. 40879/62. Heading A6M. Apparatus designed to give the operator the impression of air travel, comprises a housing provided at one side with a translucent viewing screen and containing a point source of light spaced from the screen and located inside a rotatable cylinder whose curved surface is in the form of a transparency bearing pictorial matter and lies closest to the screen in the vicinity of the upper edge of the latter. Thus the image seen expands progressively as it moves downwards past the screen, and creates an impression of travelling forwards. As illustrated in Fig. 2, the apparatus is largely identical with that disclosed in Specification 996,128, with the exceptions that the endless band disclosed in said Application is replaced by a cylinder as above, motor-driven to rotate about its horizontal axis, and the source of light 14 is arranged inside the cylinder and mounted for horizontal adjustment towards and away from the curved surface of the cylinder to give an impression of diving or climbing respectively. In the embodiment illustrated in Fig. 11, the linkage between the silhouette 42 and the shaft 44 supporting its control handle is modified to actuate means for indicating the correct positioning of the silhouette relative to targets on the cylinder 40. To this end, a collar 45 attached to the cylinder is provided with buttons 46 whose positions are co-ordinated with those of the targets. The buttons 46 are also arranged to move the flexible contact 48 of a pair of contacts 47, 48 included in a circuit to a lamp 54 or other signalling device, the arm 49 carrying the contacts being connected to the arm carrying the silhouette so that the contacts 47, 48 register with a button 46 when the silhouette 42 registers with a target.

[Also in Division C3] The invention comprises oxetanes of the formula where R and R<SP>1</SP> represent hydrogen or a C 1-5  alkyl group and R<SP>11</SP> is a C 1-20  alkyl group or a group of the formula where n is 2-5, or a group -H 2 .CH=CRR<SP>1</SP>. The compounds are prepared by reacting an ether of the formula where X is Cl, Br or I, with 1-5 moles per mol. ether, of an aqueous alkali metal hydroxide solution, preferably at 75-150‹ C. The ether reactants may be prepared by reacting an unsaturated alcohol of the formula and an alcohol of the formula R<SP>11</SP>OH with chlorine, bromine or iodine. The ethers in which R<SP>11</SP> is -CH 2 -CH=CRR<SP>1</SP> are obtained by using an excess of the alcohol in place of the alcohol R<SP>11</SP>OH. The corresponding 2-chloro-3-alkoxy propanols may be obtained as by-products of this process; when the unsaturated alcohol is allyl alcohol, some glycerol dichlorohydrin may be formed. Examples relate to the preparation of 3-methoxy-, 3- ethoxy-, 3-cyclohexoxy-, 3-dodecoxy-, 3-nbutoxy-, and 3-allyloxy-oxetane.

Abstract: 956,152. Numerical control systems. INDUCTOSYN Ltd. Nov. 30, 1960 [Dec. 7, 1959], No. 41165/60. Drawings to Specification. Heading G3N. The programmed machine tool control system disclosed in Specification 839,221 is tested by disconnecting the leadscrew drive motor and switching test signals of predetermined magnitude in sequence to the fine, medium and coarse position measuring devices. An electromagnetic stepping switch controls the test sequence. On the first step no test signal is applied, thus the error signal should be zero, and a pair of error signal sensing relays remain de-energized. This allows the switch to move to the second step when a fine position test signal is switched in from the lapped transformer arrangement disclosed in Specification 807,218. The resulting error signal should operate both sensing relays (one operates at a higher voltage than the other) so that the stepping switch moves to the third step, which removes the test signal and rechecks the zero error. The stepping switch operates on the sensing relays being alternately energized and de-energized. This process continues through the medium coarse position measuring devices. Specifications 807,219, 807,220 and 913,563 also are referred to.

Abstract: 414,408. Pleating. SIMON, A., 39, Coborn Street, Bow, and PURALI, Ltd., Murray Works, Warton Road, Stratford, both in London. Feb. 2, 1933, No. 3255. [Class 141.] In the machine described in Specification 350,907 in which blades 16, 17 with suitablyshaped edges co-operate so as to pleat the material x and emboss it along the pleating line, the blades are moved endwise automatically to vary the embossing effect. The pivotal-bars 13, 14 carrying the blades 16, 17 are connected for simultaneous endwise movement by a bar 25. A link 28 pivoted to the centre of the bar 25 is adjustably pivoted to a crank-disc 29 mounted on a shaft 30 carrying a gear 36 engaged by a rack 35 operated at the desired intervals to vary the embossing effect. A lever 33 pivoted at 32<a> to the fixed framing engages between pins 34 on the rack 35 and has pivoted thereto a cranked lever 41, 44 mounted on a fixed pedestal 38. A spring 45 tends to turn the lever 44 so as to actuate the rack 35, but this is prevented normally either by a roller 51 on a rod 52 fixed to the reciprocating presser-carriage 4 or by a pawl 39 engaging a notch 40 in the lever 33. Discs 46 mounted on the pedestal 38 are rotated intermittently by a pawl 50 on the carriage 4 engaging pins 47 thereon. The pins 47 are slidable in the discs so that some of them can be projected laterally of the discs 46 so as to engage the pawl 39 at intervals. Movement of the pawl causes the release of the levers 33, 34, so that when the position of the carriage 4, operating through the members 51, 52 allows, the spring 45 causes the rack 3, 5 to be moved and so to alter the position of the blades 16, 17. The reverse movement of the members 51, 52 restores the mechanism to its original position.

Abstract: In a method of coating articles by a fluidized bed process, the fluidized coating material is kept in a continuous circulatory movement.  The circulation may be brought about by moving a paddle to and fro immediately above the gas diffusion plate of a fluidized-bed container, or by removing part of the fluidized material from an upper part of the container and re-introducing it lower down, or by means of a conveyer device which continuously moves part of the coating material from top to bottom, or by subdividing the container into compartments into which fluidizing gas is introduced at different pressures.
