Title: Preselector electric switch mechanism
IPC: H01H43/12
Filed: 1955-11-28
Abstract: 816,332. Machine-tool details. LEBER, F. Nov. 28, 1955 [Nov. 29, 1954], No. 34056/55. Class 83 (3). [Also in Group XXXVII] A switching arrangement for selecting the speeds and feeding movements of a machine tool such as a drilling-machine, comprises a pair of control rollers 1, 2 having holes 8 arranged in circumferentially spaced groups, equally spaced along the roller axes. Each roller controls pins 11 on contact-carrying prongs 10 of a respective sheet-metal plate 9, the entry of a pin 11 into a hole 8 permitting the associated contact 12 to engage its fixed contact 13, whereas, when a pin engages the roller surface the associated contact 12 is held open. Each contact 13 is mounted on a conducting terminal block 29, the blocks being arranged in two rows parallel with the roller axes, and adjacent blocks being spaced from one another by insulating strips. Each plate 9 is carried by a block 17 fixed to a shaft 18, the two shafts 18 being interconnected for simultaneous movement in opposite directions by gear segments (Fig. 3, not shown). One of the blocks 17 is connected by a lever 23 to a solenoid 22 whereby, when the solenoid is energized, the pins 11 are moved up to their operative positions with the rollers 1, 2 and the contacts 12 are operated, de-energization of the solenoid causing a spring 24 connected to a pin 26 on the other block 17 to withdraw the pins and permit rotation of the rollers to another selected position by means of setting-knobs (not shown). To prevent rotation of the rollers when the pins 11 are in their operative positions, each roller 1, 2 has fixed on its shaft 3 a toothed wheel 36, 37, the number of teeth corresponding to the number of the possible selected positions. Detent levers 38, 39 pivoted at 19 and biased by springs 41 each have a roller 40 co-operating with a wheel 36 or 37, the levers co-operating with locking levers 43, 44 fixed to the shafts 18. Thus when the pins 11 are held retracted by the spring 24, Fig. 2, and a wheel 36 or 37 is incorrectly positioned so that a roller 40 is not located in a notch between the wheel teeth, energization of the solenoid is unable to move the pins 11 to operate the contacts 12, as shown by the engagement between 38, 43. Further, once the shafts 18 have been rotated by the solenoid, the levers 43, 44 lock the levers 38, 39 and prevent rotation of the rollers. The rollers are set by hand to give the required machine operations, contacts 13 being connected to electro-magnetically operated valves for controlling hydraulic feeds or to a mechanically operated change-speed gear, the operations being started when the solenoid 22 is energized.

Abstract: 384,094. Cathode-ray tubes ; television. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., Marconi House, Strand, London.-(Assignees of Zworykin, V. K. ; 416, Warwick Road, Haddonfield, New Jersey, U.S.A.) Dec. 16, 1931, No. 34898. Convention date, Dec. 24, 1930. [Classes 39 (i), 40 (iii), and 40 (v).] A cathode-ray tube for use in television has a fluorescent screen, a cathode, a control grid, an anode mounted relatively close to the cathode, and an auxiliary anode disposed between the anode and the grid and maintained at a positive potential substantially lower than that of the anode; As shown in Figs. 1 and 3, a cathode 11, heated by a filament 12, is enclosed in a control grid 14 having a small aperture 57, and an auxiliary anode or shield 38, which extends nearly to the envelope and has a central aperture 58, is mounted between the grid and the anode 13. The grid is supported from a pinch 43 by wires 44, the auxiliary anode is supported and insulated from the grid by wires 39 and glass beads 40, and the anode 13 is supported and insulated from the auxiliary anode by wires 41 and glass beads 42. The anode lead extends through a glass tube 50 provided with a shielding tube 52. With potentials of 1000 volts applied to the anode 13 and 45 volts applied to the auxiliary anode, a negative potential of 3À5 volts on the grid completely cuts off the ray. In general, the ratio of the potential on the anode 13 to the voltage on the grid for complete cut off is between 100 and 500, and is at least 35. The ray may be accelerated to a screen 29 by a second main anode in the form of a silver or other metallic coating 28 on the envelope to which a potential of 4000 volts may be applied. Dimensions of the electrode spacings and of the apertures are given. In another arrangement, Fig. 6, the anode 13a has an apertured base 60 extending nearly to the envelope and is mounted on the grid by wires 61 and glass beads 62, and the auxiliary anode 38a is of smaller diameter than the base 60. In a modification of this arrangement, Fig. 7 (not shown), the base and the auxiliary anode are of the same diameter and are bolted together through a ring of soapstone. The received picture impulses pass through a high-frequency amplifier 20 and a filter 19, and are impressed on the grid 14, which has a bias battery 24 with an adjustable resistance 23 and a leak resistance 31. The scanning coils 34, 36 are supplied through an amplifier 33. The circuit shown in Fig. 9 is used with a tube acting as a detector both of picture impulses and of the synchronizing impulses for the scanning coils. For this purpose the filter 19 is omitted and the leads 18, 21, Fig. 1, are connected with the amplifier 20. A resistance 75 shunted by a condenser 77 is connected in the lead 27 of the main anode, and the leads 76 are connected with the' amplifier 33. The detected picture and synchronizing impulses appear across the resistance 75.

Abstract: 425,638. Washing drinking vessels. CHAMBERS, SIR C., Monkspath Priory, Shirley, Birmingham. Dec. 16, 1933, No. 35444. [Class 138 (i)] In apparatus having washing elements for the outer and inner surfaces of drinking- vessels, the outer washing elements comprise blocks of rubber or like material arranged in spaced relationship in a direction parallel to that in which a vessel to be washed is inserted, and adapted to embrace substantially the whole of the circumference of a vessel when inserted, but with at least one gap to facilitate insertion of a vessel having a handle. In the construction shown in Figs. 2 and 3, the outer washing elements are mounted on pillars 20 and each comprises a block 21 of relatively hard rubber in which is moulded a metal sleeve of square section for engagement with the pillar. The block has an inwardly-projecting pin 22 of soft rubber, and gaps between pins on adjacent pillars permit the insertion of a vessel with a handle. The pillars 20 are associated with a central post 14 carrying spaced elements 15 of star form for washing the interior of a vessel. The elements 15 are of sheet rubber and are detachably engaged in annular recesses 16 formed in the post 14. At the top of the post a washing element consisting of four discs is secured by means of an annular groove 18 and two slots 19 at right angles to each other. Each of the four discs is engaged in a quarter of the groove 18 and a half of each of the slots 19. The washing unit is provided with rubber feet 13 for attachment to a bowl provided with a drain pipe. In a modification shown in Fig. 5, the washing unit has an outlet 50 provided with an adjustable rubber ring 29 adapted to seat in the drain hole 27 of the bowl 10. The plug has a metal liner 30 screwed on the pipe 50. The pipe communicates with a funnel 35 which is provided with an overflow outlet 36 and is adjustably mounted in a tube 33. When the apparatus is in use, liquid is continually supplied to the bowl 10, excess liquid escaping through the overflow 36. In the construction shown in Fig. 7, the portion of the apparatus for cleaning the inside of the vessel comprises a fixed base 38 and a slidable post 40 resiliently supported by a spring, both members having cleaning elements. The upper end of the post 40 carries two washing elements 46, 47 clamped in place by a bolt 48 secured to a plug 44. The post 40 is in the position shown when a relatively large vessel is being cleaned, but in the treatment of smaller vessels is depressed against the action of the spring 42.
