Title: Improvements in or relating to electro-mechanical filters
IPC: H03H9/52
Filed: 1962-09-20
Abstract: 990,299. Filter networks. SIEMENS & HALSKE A.G. Sept. 20, 1962 [Sept. 22, 1961], No. 35789/62. Heading H3U. A band-pass filter includes an electromechanical filter unit F with an odd number, greater than unity, of mechanical oscillators and a capacitive coupling C between the output and the input of the unit. As shown, the input and output comprise tuned circuits whose capacitances may be derived wholly or partly from the electrostrictive transducers of the filter. A series-tuned circuit may replace the parallel-tuned circuit in the input. If the input and output are in antiphase, the capacitive feedback produces an attenuation pole at the lower limit of the pass-band. When input and output are in phase, the pole appears at the upper limit. To obtain a desired phase relationship, the output may include a 1 : 1 or 1 : - 1 transformer. The specification includes a discussion of the effect of capacitive feedback on electromechanical filters having both odd and even numbers of resonant elements.

Title: Wire printer
IPC: B41J2/24
Filed: 1954-12-20
Abstract: 767,432. Typewriters. INTERNATIONAL BUSINESS MACHINES CORPORATION. Dec. 20, 1954 [Dec. 23, 1953], No. 36725/54. Class 100(4) The print wires of a wire printer are selectively operated by drive wires when perforations in a number of adjustable tapes come opposite the drive wires and allow them to be moved yieldingly through the tapes and then positively to effect the operation of the print wires selected. Print wires 30 are extended from a housing 32 to effect printing through a ribbon 20 on to a record sheet 14 passing round a platen 12. The rear ends of the print wires 30 pass through a plate 38, Fig. 3, and into a plate 36 where they end in heads 48. The wires are held retracted by springs 44 interposed between the plate 38 and collars 43 fast on the wire. The print wires are operated by drive wires 52, actuated by a bail 50, striking their heals 48 after passing through perforations in the tapes T1...T8. The bail 50 is reciprocated against the action of springs 56 by cams 54 so that the teeth 64 of pawls 66 engage lugs 62 on the wires and move them through the tapes if perforations are present. The rear of the drive wires extend into openings 82 in a reset bar 28 which also has holes 72 housing extensions 74 on the teeth 64 so that, if a drive wire strikes an unperforated part of the tape, the pawl 66 is allowed to ride over the wire lug 62, but, once the drive wire has passed through the tapes, a protuberance 76 holds the pawl against the wire so that it is driven positively as it engages and moves the print wires. The drive wires are restored either by the pawls 66, where these have passed the forward side of the lugs 62, or by cooperating shoulders 78, 80 on the drive wires and bail respectively. The print wires extended to form selected characters are controlled by the movement of one of the tapes T1...T8 from its rest position. The tapes mounted in guides 83a, 83b are attached at one end to springs 84 tending to move them from their normal position in which they are held by a positioner bar 88 attached to a spring 92. The tapes are also held in the normal position by a bar 96 of the tape selector mechanism 22. A slot 100 in the bar 96 allows the tape it is aligned with to move up under the action of its spring 84 an amount determined by the movement of the bar 88. Three magnets TS1...TS3 acting in combination through bell-cranks 104, 106, 108 can align any one of the tapes T1...T8 with the slot 100 allowing the bar 88 to move it to any one of seven positions by the action of magnets TP1...TP3 acting through similar bell-cranks. Thus any one of 56 portions of the tape can be positioned in front of the drive wires giving the necessary perforations to allow the drive wires to actuate the necessary print wires for any of 56 characters. Modified drive means for the drive wire using two pawls which may be formed by the ends of spring wires are described. Specification 638,935 is referred to.

Abstract: 1281942 Polyacrylonitrile fibres MITSUBISHI RAYON CO Ltd 36949/69 Heading B5B [Also in Division D1] An acrylonitrile polymer or copolymer fibre having an outer layer insoluble in dimethyl formamide at 75‹ C. which layer comprises ridges of more than 0À2 Á height at intervals of 1À5 to 12 Á in the plane of the longitudinal axis of the fibre may be produced by treating the fibre with a denaturalizing agent, defined as a chemical agent which makes the outer layer of the fibre insoluble in dimethyl formamide at 75‹ C., immersing the treated fibre in a shrinking agent and heating the fibre thus treated. The denaturalizing agent may be an aqueous solution of alkali or alkaline earth metal hydroxides, sulphuric acid, hydroxylamine salts or hydrazine. The shrinking treatment comprises either (a) immersing the fibres in an inert (non-solvent) heating medium at above 130‹ C., (b) immersing the fibres in a glycol solution of organic carbamate below 70‹ C. and subsequently heating to above 70‹ C., (c) immersing the fibre in solution (b) at above 70‹ C., or (d) immersing the fibres in a glycol or aqueous solution of the organic carbonate at below 70‹ C. withdrawing the fibres from the solution and squeezing the fibres so that the solution remaining on the fibres is less than 200% of the weight of the fibres and heating the fibres to above 70‹ C. In example 10 a conjugate fibre of acrylonitrile copolymers is spun, drawn, crimped and then treated according to the invention, with a bleaching step between denaturalizing and shrinking. The ridges may resemble a tuck, the edges of which are at an angle of 75 to 105 degrees to the plane of the longitudinal axis of the fibre, said tucks running discontinuously around the fibre circumference. The cross-section of the protuberances may be asymmetrical through a plane through the top of each ridge so that the fibre exhibits a differential frictional effect along its axis i.e. the frictional force required to pull a filament from a parallel bundle is different in both directions along the longitudinal axis of the fibre. The fibres so produced have a hand closely resembling wool and superior anti-pilling properties to wool and show a multicolour effect when treated in a bath of mixed dyes.
