Title: Improvements in or relating to television or other signal transmission systems
IPC: H04N5/16
Filed: 1938-05-30
Abstract: 515,360. Television. BLUMLEIN, A. D. May 30, 1938, No. 16080. [Class 40 (iii)] Auxiliary signals 2, which annul the difference between a recurrent reference amplitude (e.g. interruptions) and a related datum level (e.g. black), are added to television or like signals 1 prior to a point where the datum level is established so that the stabilization of the datum level is independent of changes in the gain of the signal channel prior to the point of stabilization. The television signals are generated by a cathode-ray scanner, the beam of which is periodically cut off by black-out pulses to introduce the interruptions, and the auxiliary signals are derived from the source of black-out pulses or from the beam current of the scanner by a resistance in the cathode lead, Fig. 2 (not shown). The auxiliary signal is added by a valve 4 in parallel with an amplifier 3 prior to a gain-controlling stage 5. The amplitude of a further auxiliary signal, which is added to the television signals to correct spurious signals such as "tilt" after the stabilization of the datum level, is controlled in a valve 8 simultaneously with the control of the television signals so that the correction of tilt is independent of the gain of the signalling channel. Specifications 442,666, 449,242, 462,110 and 490,845 are referred to.

Abstract: 236,915. Westinghouse Lamp Co. (Assignees of Lederer, E. A.). July 9, 1924 [Convention date]. Copying telegraphs; thermionic relays. - A lighting tube suitable for use in the telegraphic reproduction of pictures with or without wires is provided with ionizing electrodes, one o which is of small area so as to restrict the ioniz ing current. and with means for producing a positive column glow discharge. The ionization may consist of a wire 3, Fig. 1, wound helically about a leading-in wire 6, and of a surrounding tube 4. These are situated within a constricted part of an inner tubular chamber 2, above the open end of which a cathode 5 is held by clips 13. A central hole in the disc-shaped electrode 5 allows light from the positive column to issue. The electrodes may be of aluminium, and may be coated with an alkali metal which is distilled from a side-tube 15<1> after sealing the container Suitable gaseous media are helium and neon preferably at a pressure below 12 mm. of mercury. Two of the leading-in wires 6, 7 are surrounded by separate tubuLar extensions 8 of the chamber 2, to prevent stray discharges. In another construction the ionizing electrodes consist of a plate and a flat spiral, and the cathode is a cylinder surrounding the chamber, which is constricted at its upper end. Variation of the luminous intensity may be produced by varying either the ionizing current or the main current. Thus, the cathode 5 may be connected to one of the ionizing-electrodes 3, 4 by a battery furnishing a steady current, while the ionizing-electrodes are connected through a microphone and a battery. In another arrangement, current flows from a positive main 23, Fig. 4, to one ionizing- electrode 4, through the tube to the main electrode 5, and thence to the anode 25 of a thermionic valve, the cathode of which, like the ionizing electrode 3 of the luminous tube, is connected to the negative main 23. The grid 27 of the valve is maintained at a lower potential than the anode 25 by a battery 26. between which and the anode a microphone 20 is connected. For controlling the luminous tube in accordance with current variations transmitted by wireless telegraphy, the circuits of the luminous tube and anode of the valve are as shown in Fig. 4, but the grid 28, Fig. 5, is connected so that the valve acts as a detector.

Title: Furnace
IPC: F27D11/02
Filed: 1960-05-06
Abstract: 881,984. Metal heating furnaces; cooling furnace charges. BUKATA, S. May 6, 1960, No. 16167/60. Class 51 (2). [Also in Group XI] In an electrically heated brazing furnace including removable top and bottom sections 22, 24 and a pair of envelope sheets 32, 34 held apart by a channelled closure member 42 grooved at 64, 66 in its faces juxtaposed to the sheets, the grooves contain gaskets 68, 70 and channelled members 40, 42, 44 form an outer casing through which cooling fluid passes. The envelope sheets 32, 34 are corrugated to allow for thermal expansion and one of these (member 32, Fig. 6, not shown), may be of " concertina " form so that the heating space defined between the sheets and a perforated spacer of suitable size may accommodate articles, such as laminated structures, of varying size. The heating space is evacuated through tube 82 and may be provided with an inert gas atmosphere of, for example, helium or argon through pipe 86. Heat equalizing elements such as graphite blocks 90 may be provided. Various modifications are described in which one of the graphite blocks is disposed inside the heating space or between the lower envelope sheet and a third like corrugated sheet. In such arrangements the block additionally serves to support the charge and the furnace cover is removed hydraulically. A variety of casings for furnace assemblies mounted on wheels, rollers and the like are described (see Figs. 12, 14, not shown). In these larger arrangements provision is made for the introduction of cooling gas and liquid from tanks 324, 326, Fig. 11, into the heating element space 232, 234, so that heated structures may be rapidly cooled to room or subzero temperatures. Thus coolant gas is admitted into the housing from tank 326 by opening valves 329, 336 and 344. After the structure 212 has been cooled by gas entering spaces 232, 234 liquid coolant from tank 324 may be introduced by opening valve 328, and passing it through pipes 340, 342, 348 and 350. Expansion of the liquid as it emerges from nozzles in the ends of the said pipes causes it to supercool the structure. Thus it is possible to heat and cool the structure 212 several times if necessary without removing it from the furnace.

Patent GB-163209-A (GB)
Abstract: 163,209. Trinks, F. May 17, 1920. Multiplying and dividing apparatus.-Relates to machines of the cam-disc and pin-wheel type and consists in utilizing known mechanism for (1) adding a unit's digit to the revolutions-counter in changing from a positive to a negative reading (made upon alternative series of figures elected by a reading-aperture slide) by means rendered operative from the zeroizing-shaft of the revolutions-counter (2) indicating whether the revolutions-counter has been zeroized from the zeroizing- shaft, (3) shifting and locking the reading-aperture of the revolutions-counter. On the zeroizing- shaft 13 of the revolutions counter is fixed a disc 11 with a pin 10 arranged to put into operative position a shifting lever 8 placed in front of the units drum. A disc 15 on the driving shaft 6 carries a deflecting pin 14 and cam surfaces 20, 21, arranged so that after zeroizing by the handle 16, a positive revolution of the shaft 6 replaces the lever 8, and a negative revolution results in a digit being added to the units drum and the lever 8 afterwards replaced. To indicate whether the counter has been zeroized by the handle 16 and consequently the lever 8 cocked, a projection 40, Fig. 6, with a pin 41 has a sloping face 42 spring-pressed against a sloping face 44 of a pin 43 attached to slide 50 which carries an indicating mark which shows through an aperture in the cover 48. For shifting and also locking the reading-aperture slide a disc and a pin similar to those shown in Fig. 1 are fixed to the zeroizing-shaft 13 for setting a shifting lever 29, Fig. 11. Upon zeroizing, the lever 29 is set and the slide is unlocked by a disc 68 displacing a pawl 54 from a notch 64 in the slide, and the slide is displaced to the positive position by a sloping surface 66 and a pin 67, in which position it is locked by a projection 53<1> on a spring pawl 53 engaging a plate 55 attached to the slide. Upon positive rotation of the shaft 6 a cam 37 sets the lever 29 in operation, and slide remains locked. Upon negative rotation, the pin 30 rotates gears 58, 56, so that a disc 1, loose on the zeroizing shaft, unlocks the slide by means of a projection 61 which presses back the pawl 53, and shifts the slide to the negative position through the agency of a cam 60 displacing a pin 59 on the slide. Means are also described for shifting the slide without locking.

Abstract: 387,216. Washing-machines. INVENTIA PATENT - VERWERTUNGSGES., 10, Herrenacker, Schaffhauaeri, Switzerland. - (Assignees of Krauss, F. E.; Schwarzenberg, Saxony, Germany.) June 10, 1932, No. 16442. Convention date, June 11, 1931. [Class 138 (ii).] A rotary washing-machine having a directlyheated motor-driven receptacle is provided with means to prevent both the heater and the motor being operative simultaneously. In Figs. 1 and 2 the electric or gas heater 13 and the motor 8 driving the pinion 9 which engages the driving rim 7 of the receptacle 3 rotating about an inclined axis, are carried by arms 10, 12 spaced apart by 90‹ on a vertical shaft 11 so that only one may be in operative position. The upper trunnion 4 may be hollow to permit escape of air during heating, or a relief valve may be provided in the cover of the drum, or an arm 24 may be provided on the shaft 11 which prevents the heater from being moved to operative position until the cover 6 is raised, after which the arm 24 engages beneath and retains the cover open. A mechanical interlock between the switch 17, Fig. 3, of the motor circuit and the switch or tap 20 of the heater comprises a disc 14 on the shaft 11 having two radial notches in its periphery spaced apart by 90‹, and a disc 18, 21 each having one radial notch 19, 22, on the rotatable member of each switch or tap. In Fig. 5, when the motor is in the operative position a pin 28 projecting through a hollow arm 26 in the shaft 11 is engaged in a slot 29 of a guide 30 and the shaft 11 cannot be rotated until the connector plug 25 of the motor 8 is plugged into the arm 26 to force back the pin 28 and piston 27. A flange 31 on the guide 30 prevents withdrawal of the connector plug from the hollow arm whilst the motor is in the inoperative position and the heater is in operative position. In another modification the motor and heater are stationary but their controlling switch and tap are provided with inter-engaging parts that prevent simultaneous operation of both. In another form, Fig. 11, the swinging of the heater 13 into position simultaneously moves a tensioning roller 40 out of contact with a driving belt 34 whereby the drive from the stationary motor shaft 9 is not transmitted to the pulley 35 on the drum 3. In another form wherein the heater is swung into operative position this action puts a forked member on the frame carrying the heater into the path of a lug projecting from the drum thereby preventing the latter from rotating. In another form, Fig. 13, the supply of gas to the heater 13 operates a diaphragm motor 45 to raise a rod 46 into locking engagement with the toothed driving rim 7 of the drum.
