Title: Improvements in and relating to starting and stopping devices for sound recording and reproducing apparatus using two or more record carriers
IPC: G11B17/00
Filed: 1930-06-11
Abstract: 363,391. Sound recording or reproducing apparatus. FRIESS, H., 232, Friedrichstrasse, Berlin. June 11, 1930, No. 17901. Convention date, March 20. [Class 40 (ii).] Relates to starting and stopping devices for sound-recording or reproducing apparatus using two or more sound record carriers F, G, each of which is controlled by an electric relay A or B, held in position by electromagnets 22. According to the invention, the relays are connected up alternately by a central switch D and are each provided with two contacts, one 19 controlling the record carrier, preferably through electromagnets 27 or 53, and the other 21 controlling the change over of the central switch preferably through a working relay C. The central switch shown is of the rotary type the shaft 50 of which carries rings 1, 2, contacts 11, 2<1>, on which engage alternately with fixed contacts 24,51 or 9, 52 respectively when the shaft is rocked through 180‹ by an electromagnet 49 controlled by the working relay C. The closing of a switch 3 either by hand or by contacts on a picture film establishes first a circuit from a battery through leads 10, electromagnet 11 and return leads 13, 14. By the attraction of the bell crank 16, contact 19 is closed to energize the retaining electromagnet 22 and contact 20 is opened to break a circuit through electromagnet 27 and allow the record 35 to fall on to a continuously rotating turntable 36. The arm 18 of the bell crank 16 is so arranged that the contact 21 of the relay A is closed only when the switch 3 is again operated. The electromagnets 40 controlling the working relay C are then energized, contacts 44 closed, and a circuit established through the electromagnet 49 actuating the switch D the rocking of which cuts out the relay A and brings in the relay B. The contact 20 of this relay completes the circuit through the electromagnet 53 and causes its armature 55 to rise and stop the record 54. Lamps 32 or 58 are lighted to show which record is out of action. Electric pick-ups 65, 67 in association with the records are connected to a short-circuiting and fader switch E mounted on the shaft 50 of the central switch D. Fig. 2 shows a face cam 78 which is rocked through a small angle by the electromagnet 49 to cause the fall of an arm 77 on the shaft 50 and the clutching of the switches D, E with a continuously rotating pulley 74 which then rotates the shaft 50 through 180‹ until the cam 78 raises the arm 77 and declutches the shaft.

Abstract: 1489792 Selective printing TELETYPE CORP 1 May 1975 [8 May 1974] 18314/75 Heading B6F Line feed of platen 39 is effected by the selective engagement of platen gear 102 with gear 107 when solenoid 97 is energized. Stepping motor 22, which drives a carriage 17 carrying a needle printer 15 by rotation of lead screw 20 also drives gear 107. Thus motor 22 can simultaneously effect character spacing and line feed. The screw 20 and gears can be proportioned so that a single line feed occurs for every character space moved by the carriage 17. Solenoid 97 is energized for normal single line feed when the carriage is outside the printing margin. Gear 102 is on a plate 105 pivoted about pin 118 and its drive is transmitted to the platen 39 by an Oldham coupling, Fig. 9 (not shown). Energizing the solenoid 97 pivots armature 99 about pin 138 so that its end 99a rocks the plate 105 to engage gears 102, 107. As gear 102 is then caused to rotate, a ratchet arm pivoted about pin 143 and coupled to the armature by pin 138 is rocked by ratchet wheel 144 towards the solenoid 97. As it is still energized, the end 99c is attracted and the ratchet arm held clear of wheel 144. The solenoid 97 may remain energized to permit multiple line feed without the ratchet having to re-engage for each line space of the multiple feed.

Abstract: 573,740. Making seamless tubes from powdered metal. NEWTON, E. P. (Callite Tungsten Corporation). Nov, 4, 1943, No. 18343. [Class 82 (i)] [Also in Group XXII] Seamless tubes are made from powdered refractory metals such as tungsten, molybdenum, tantalum and niobium by pressing a layer of the powder in a mould 1 on a support 2 then placing above it a core 5, of some material that will melt at the sintering temperature, for example, a glass rod, and finally adding the remainder of the powder for compression by the side'3 to the amount of from 10 to 20 tons per sq. inch. The compact is removed from the mould, is resistance heated between two electrodes extending parallel' to but on opposite'sides of the core which is arranged vertically. During the sintering, the core runs out and is replaced by a metal core, after which the tube is completed by swaging, rolling or drawing. Electric induction heating may be employed. Borosilicate glasses, quartz, sillimanite, the material known under the Registered Trade Mark " Pyrex," and carborundum may be used. If metal be used as a core, its coefficient of expansion should not exceed that of the tube . metal and it should not alloy with it. For a molybdenum tube, a tungsten core may 'be used, coated with oxide of beryllium, manganesa, zirconium or thorium. In this case, the core remains in place for the final working. Alloy or composite tubes may be made from several of the powders. Alloys of nickel, iron and chromium may be used for cores and particularly the alloy of nickel and steel known under the Registered Trade Mark " Invar."
