Title: An improved typewriting machine for embossing paper according to the braille or like code systems
IPC: B41J3/32
Filed: 1945-03-05
Abstract: 622,096. Braille and like typewriters. TEJEDO, J. DE LA F. March 5, 1945, No. 5509. [A Specification was laid open to inspection under Sect. 91 of the Acts, July 16, 1945.] [Class 100 (iv)] In a typewriter for embossing in Braille or like characters for the blind, each embossing or indenting member 11a is operated by an electrically-actuated device, e.g. an electromagnet 10, and each key 7 carries a contact which during its depression moves over a number of contacts corresponding to the electromagnets so as to operate those members 11a whose electromagnets are connected to their corresponding contacts. The members 11a (two lines of three for Braille) which co-operate with an anvil, are slidable vertically in a turret 14 and normally held depressed by springs 80 bearing against feet 11e thereon. When an electromagnet 10 is energized, it causes a hammer 11 to strike the foot 11e of the corresponding member 11a so as to indent the paper. Each key 7 carries an insulated plunger 7c sliding in a housing 9 connected to one pole of a battery 13, the other pole being connected to the electromagnets 10..An insulated block 8 in the housing 9 carries six contacts 92, one or more of which may be connected to the respective electromagnets 11 according to the letter &c. represented by the key. In the plunger 7c, two contacts 94, 95, spring-pressed apart, wipe over the housing 9 and contacts 92 respectively, when the key is depressed to actuate consecutively the members 11 which represent the letter. A spring 89 restores the key which during its return, again actuates the members 11, thus forming deeper impressions. Specification 622,183 is referred to. According to the Specification as open to inspection under Sect. 91, two shafts, each carrying three eccentrics, are continuouslydriven from a motor. Each eccentric is adjacent to one of the hammers 11, and energizing of an electromagnet moves a member on its hammer into engagement with the eccentric, so that the corresponding indenting-member 11a is caused by the eccentric to make an impression. Further, eight indenting-members 11a may be employed'to mark the paper to represent music by the " Abreu" system. This subject-matter does not appear in the Specification as accepted.

Patent GB-406865-A (GB)
Title: Improvements in and relating to the conversion of mechanical oscillations into sound waves by electromagnetic means
IPC: H04R1/46
Filed: 1933-02-23
Abstract: 406,865. Pianofortes. DREGER, K. VON, 30, Bambergerstrasse, Berlin, and BEIER, F., 78, Treuenbriezenerstrasse, Luckenwalde, both in Germany. Feb. 23, 1933, Nos. 5570 and 5571. Convention dates, Feb. 23, 1932 and Sept. 21, 1932. [Class 88 (ii).] Musical instruments such as pianos with electro magnetic means for converting into sound-waves the mechanically produced oscillations of steel strings 1, or strings partly metallised with steel, have the strings formed as permanent magnets instead of the cores 4 of the electromagnetic pick-up, which latter are of soft-iron. The oscillations of the string 1 are converted into electrical oscillations in a coil 5 of the pick-up, which oscillations are amplified and reproduced in loud-speakers. The string is preferably only magnetized over a small region adjacent the magnet-poles and, in order further to reduce this region, a single pointed magnetpole may replace those shown in Fig. 1. The extent of the magnet poles is limited to not more than one-third of the wavelength of the string. The laminated soft-iron pick-up cores 4 are arranged near to the point of support of the strings on a strut 3, and are mounted with an adjustable screw-and-slot connection 9 on a diagonally -extending support 11. In the case of a piano having eighty-five strings, the pickup coils 5 are connected with the amplifier in five parallel groups of seventeen in series. The strings are magnetised before each performance by passing through the pick-up coils 5 direct, pulsating, or intermittent current derived from the mains through a valve rectifier. An automatic time-switch is provided which, after a predetermined magnetising interval disconnects the magnet-coils from the current source and connects them with the amplifier in readiness for a performance. The Specification as open to inspection under Sect. 91 states also that in order to have a continuous magnetizing effect on the strings a pure direct-current from a dry-battery or an accumulator may be superimposed on the oscillating current generated during a performance. This subject-matter does not appear in the Specification as accepted.

Title: Machine tool with travelling tool changer
IPC: B23Q3/157
Filed: 1965-02-09
Abstract: 1,037,728. Tool-changing. KEARNEY & TRECK CORPORATION. Feb. 9, 1965 [Feb. 12, 1964], No. 5662/65. Headings B3B, B3C and B3K. In a machine tool, a tool transfer member 76 is carried by an extensible guide means 120, 121 which is adjusted automatically according to the relative movements of a tool storage means 71 and a tool spindle 55. The spindle is rotated through speed-change gearing by a variablespeed hydraulic motor 62 on a headstock 50. The headstock is traversed by a ball screw-andnut 53 rotated by a motor 51 on a column 41 traversable on a bed 40 protected by sliding covers 44, 45. Similarly, a saddle 64 is moved to-and-from the column and carries an indexable work-table 63. The sequence of operations in a tool-change is: movement of the transfer member 76 from the position of Fig. 1 to pick up a selected tool from the drum and return, vertical movement of the spindle 55 to align it with the transfer member when an operation has been completed and the work retracted, movement of the member 76 to replace the old tool with the new in the hydraulically-operated collet, return movement of the member 76 to replace the old tool in the store, and return to the initial position. Each tool is identified by coded rings and the store is rotated by a motor 90 and gearing 92. The tools are selected by data impressed manually or automatically. A reading head 95 is swung aside by hydraulic means when a tool has been selected. The store is rotated to position the tool at a fast rate and slightly over-runs, the rotation is then reversed at a slow rate and a cam ensures exact positioning of a tool opposite the tool transfer means 76. (In a modification, the position of the store is selected instead of a tool in the store). The guide rods 120, 121 for the transfer member 76 are attached to the column 41 and slide through guides 123, 124 and 126 as the column is adjusted. The member 76 is traversed by an hydraulic means 130, speed of traverse being reduced when the member approaches a tool in the spindle 55. The transfer member 76 comprises two pairs of work-gripping fingers 77, 78, the fingers 77B, 78B, Fig. 4 (not shown), each being actuated by a fluid-pressure device such as 182 which moves a slotted cam-plate 191 to swing the finger, at the same time moving a switch-operating rod 211 by means of a cam 213. The fingers are mounted on a shaft 152 oscillated by a fluid-pressure device actuating rack gearing on a slide movable axially of the tools by further fluid-pressure means on a bracket 135. The machine may be controlled manually or by signals obtained from a punched or magnetic tape. The tape reader is contained in a control cabinet 452 on a bridge 453 across the bed 40.
