Filed: 1926-12-13
Abstract: 286,799. CrotI, W. r. Dec. 13, 1926. Ribbon and tape machines. - An attachment for gramophones, dictating machines and the like where - by a record may be made on a strip or thread passing between reels, or sound reproduced from such a record, is arranged to be driven from a rotating part of the gramophone, &c. The attachment mav be adapted to record or reproduce two such records simultaneously. As shown in Fig. 1 the attachment comprises a diamond-shaped frame e upstanding from a bar which is adjustably clamped to the gramophone casing b so that a spindle f mounted ou the frame can be coupled to the turntable spindle a. The spindle f is positively geared through reversing gearing i, i<1>, with a spindle, l<1> carrying a record-feeding bobbin l<3> and a pulley l<2> which drives by a band m two spindles m<3> spaced apart on the frame e and carrying the reels n<1> on which the strip or thread record is wound. The reels n<1> are frictionally connected with their spindles through discs m<5>, m<6>, and the record strip or thread o is led from one reel over a support or anvil p, over a. guide roll p<1>, down and around the feeding bobbin l<3> and up over the roll p' to the take-up reel. The sound-box r<1> connected by a flexible tube with the horn is supported by a bracket r from the frame e so that the stylus rests on the strip or thread passing over the support p. Rewinding of the record is effected by the reversing gear i, i<1>. When two records are to be reproduced simultaneously, the spindles l<1>, m<5> are extended to carry the additional reels, and the anvil p and pulleys p<1> are duplicated. In a modification, Fig. 5, the two reels n<4>, n<5> are mounted on a bar s pivoting about the anvil p which is carried by a frame, d<4> attached to the. gramophone casing b. A spring t<1> pulls the bar s so that the coils of the record on the reel n<4> are pressed against a friction roll t on the turntable spindle so that the record thread is drawn off th& reel n<5>, between guide pins p', p<3> and over the anvil p. By swinging the bar to the dotted position the record can be rewound. The bar s may be dispensed and the reel n<4> secured on the turntable spindle. In another modification, Fig. 9, the attachment frame supports two pivoted bell-cranks x<1>, x<2> carrying the record reels n<6>, n arranged so that the record coils bear on a friction rod fixed on a spindle w<2> carried by an arm w<1> from the attachment frame. The spindle w<2> lies above the turntable spindle a and carries at each end a. friction wheel driven from the turntable and each capable of being secured to the spindle separately by feather keys on a rod w<6> inside the spindle w One of these friction wheels is nearer the centre of the turntable than the other and is employed in rewinding. Either reel can be held clear of the friction roll on the spindle w<2>, according to the direction of reeling, by means of a hand-actuated cam y.

Title: Self-filling fountain pen
IPC: B43K5/04
Filed: 1920-11-10
Abstract: 175,070. Imray, O. Y., (Dunn-Pen Co. Inc.). Nov. 10, 1920. Reservoir pens. - Relates to self-filling reservoir pens of the kind in which the feed-piece is bored to receive the end of an air-tube communicating by a lateral duct with the ink-feed passage and extending upwardly to communicate with the reservoir at the end of the pen remote from the nib, the reservoir being provided with pressurevarying means so that the pen may be filled by repeated variations in the pressure, air being expelled through the air-tube on each increase of pressure and ink flowing in through the feed passage in the next decrease of pressure. The pressure variations in the reservoir are imposed on both the ink in the reservoir and the contents of the air-tube 7, so that any outflow of ink through the unrestricted ink-feed passage 5 on an increase of pressure in the reservoir acts to draw out the contents of the lateral duct 6 and air-tube 7 by ejector action. The air-tube 7 may be of higher fluid resistance than the passage 5. The pressure-varying means, permanently in connection with the reservoir, may comprise either a cylindrical piston 3, Fig. 1 with a ring 12 smaller than the interior of the reservoir so that the annular space between the piston 3 and the barrel of the pen may serve as part of the ink reservoir, or an elastic sac 15, Fig. 4, wedged at its lower end between the screw-plug 21 and the interior of the barrel and attached at its upper end to a rotatable cap 17 by the engagement of a beaded flange 16 on the sac 15 with corresponding recesses in the cap 17.

Title: Improvements in or relating to earthing switches for radio receiver aerials and the like
IPC: H01H29/00
Filed: 1929-10-21
Abstract: 335,406. Kramolin, L. L. von. Oct. 21, 1929. [A Specification was laid open to inspection under Sect. 91 of the Acts, Oct. 21, 1929.] Protective arrangements.-An outside earthing switch for a wireless aerial comprises an arcuate tube b containing mercury and mounted in a disc a of insulating and non-corroding material. The disc a is fitted with a shaft e, which acts as a lead-in device, and is operated by a handle g located indoors. In the position shown, the aerial c is directly earthed at h. By rotating the disc in a clockwise direction, the aerial is connected through the mercury and a condenser f to the input terminal d of the wireless receiver. The tube b is filled with a readily-ionized gas such as argon and the electrodes may be made of alkali metal and brought out in the form of opposed plates k so that heavy potentials are discharged to earth in both positions of the switch. A second, more coarsely-adjusted spark-discharge device may be arranged on the disc a. The arrangement is of general application as a potential discharger, the pronounced quenching effect of the mercury arc serving to interrupt the discharge directly the voltage has dropped below the danger point, thus safeguarding the source from prolonged earthing.

Abstract: 1,239,781. Control of D.C. motors. AGFA-GEVAERT A.G. 10 July, 1968 [11 July, 1967], No. 32822/68. Heading H2J. [Also in Divisions G2 and G3] Fresh processing liquid is supplied to a continuous photographic developing apparatus by a dosing pump driven by a variable-speed motor 64, the speed being varied in correspondence to the width of material being processed as sensed by switches 11-19 in the speed control circuit of the motor, each switch and an associated resistor 33-41 being connected in parallel. The motor is a direct-current motor with permanent field magnetization, and the speed is regulated by the current derived from a tachogenerator 63 fitted on the motor shaft. During operation, a change-over switch 6, controlled by a rotating cam on the drive arrangement for photographic material through the apparatus, periodically discharges capacitor 5 through a relay 8 to close contacts 8a and bridge the thyristor 78. After capacitor 5 is discharged, contacts 8a open again and relay 61 drops out, closing contacts 61a and opening contacts 61b. The motor 64 then runs at a speed depending upon the voltage drop across resistor 57 and until thyristor 78 fires at a time determined by timing circuit arrangement 70-77. A basic control of the motor independent of the width of the material is given by relay 21 when energized closing contact 21a. A manual switch 20 enables supply of fresh processing liquid to be manually pumped, the resistor 43 being selected to give a maximum pumping speed. The closing pump, Fig. 2 (not shown), has a camshaft (81) having three control cams (82a, 82b 82c) operating diaphragm pumps (83), (84), the quantity of fluid pumped per stroke being regulated by screws (85), (86).
