Title: Improvements in or relating to thermionic valves
IPC: H01J21/18
Filed: 1925-01-08
Abstract: 227,452. Habann, E. Jan. 11, 1924, [Convention date]. Vacuum tubes. - In a valve. of the type in which the discharge is influenced by at least one constant electric field and one constant counteracting magnetic field, so as to act as a negative resistance, a filament is mounted between two anodes and two positive and negative auxiliary electrodes, all arranged to form a box or hollow body which is substantially closed on at least four sides. The open end of the box &c. may be closed by negatively-charged covers. As shown in Fig. 3 the anodes b, b<1> and auxiliary electrodes c, d form a rectangular box enclosing the filament a, and a magnetic field is produced by an electromagnet, not shown, arranged axially with the filament. The electrode d may be negatively charged by impact of electrons, or by connection with an external source. The electric and magnetic fields are in opposition only in relation to electrons passing to the anode b. No current passes to the anode b<1>. The functions of the electrodes b, b<1> may be interchanged by reversing the magnetic field. In a modification the electrodes are curved, the anodes being narrow, and the auxiliary electrodes in the form of semicylinders. The anodes mav be combined to form a semi-cylindrical anode surrounding a semi-cylindrical auxiliary grid. In the arrangement shown in Fig. 8 the anodes are combined to form a grid b<2>, surrounded by the negative auxiliary electrode d, and the active parts f, f<1> of the anode are formed of thicker metal or with corrugations or ribs g for cooling. The positive auxiliary electrode c is of semi-cylindrical shape. In another modification a single positive auxiliary electrode and a single anode, both of semi-cylindrical shape, are mounted around a cathode. Specification 182,105 is referred to.

Title: Improvements in methods and apparatus for making dry carbon dioxide products
IPC: C01B32/55
Filed: 1930-01-07
Abstract: 346,367. Liquefying carbon dioxide. DRY ICE CORPORATION OF AMERICA, 52, Vanderbilt Avenue, New York, U.S.A.-(Assignees of Jones, C. L. ; Pelham, New York, U.S.A.) Jan. 7, 1930, No. 591. Convention date, Feb. 21, 1929. [Class 8 (ii).] A stream of liquid carbon dioxide is cooled by partial evaporation to freeze water and other impurities, and the frozen impurities are removed from the still liquid carbon dioxide. The gas is compressed in compressers 10 .. 12, Fig. 1, and passed through a coil 15 within a condenser 16 and thus liquefied. The liquid is expanded through a nozzle 18 into an evaporator 19. The expansion causes freezing of water &c., the crystals being caught in a fine mesh basket 24. The liquid flows to second and third stage evaporators or direct to the expansion nozzle of a snow chamber 23 or to other apparatus. Gas flows through a valved pipe 20 to the inlet of the third stage compresser, or the pressure in the chamber 19 is otherwise suitably maintained. The basket 24 is removable by removing a plug 26. Fig. 2 shows a modification in which the liquid enters through an expansion nozzle 18a, 18b at each end of a long chamber, straining baskets being provided at each end. Gas escapes by an outlet 20a and liquid by an outlet 21b. The crystals may be melted by an internal or external coil 37a, 37b, the liquid produced being blown off or led to traps through outlets 38a, 38b. Dams 36a, 36b prevent this liquid from mixing again with the purified liquid carbon dioxide. Fig. 3 shows apparatus in which the gas does not flow through the basket 24x but escapes by a pipe 20x above the inlet pipe 17x ; a liquid outlet 20z is provided near the base ; the level may be tested by cocks V.

Title: Means for supporting mechanically vibrating elements such as piezo electric crystals
IPC: H03H9/09
Filed: 1937-01-08
Abstract: 488,564. Piezo - electric crystals; electromagnetic resonators. STANDARD TELEPHONES & CABLES, Ltd. Jan. 8, 1937, No. 615. Convention date, Jan. 30, 1936. [Classes 40 (iii) and 40 (v)] Undesired oscillations in crystals and other resonators are damped out by means of soft metal. In crystals cut parallel to the electric axis, so that the frequency is independent of temperature for transverse vibrations propagated normally to the crystal-face, instability of resonance, due to coupling between the transverse vibrations and longitudinal vibrations propagated parallel to the face, is prevented by damping out the longitudinal vibrations with soft metal in such a way as to prevent the formation of longitudinal standing waves by reflection. In the arrangement shown in Fig. 4, the crystal 7 has bevelled edges engaging the corresponding edges of a screw-threaded ring 9 which, with the base 2, forms a cup-shaped receptacle into which the crystal is pressed by an adjustable spring 5 acting through a disc 6. The bevelled edge of the ring 9 is coated with a soft metal such as tin or lead for damping out the undesired vibrations. Undesired oscillations in metallic bars may be similarly damped with soft metal. The Specification as open to inspection under Sect. 91 comprises also the following subject - matter. A strip - shaped crystal 20, Fig. 5 (Cancelled), may be supported by pins 16 which project respectively from a blade 14, having a bend 21 for purposes of adjustment, and from a troughshaped plate 4 provided with a flat at 5. The undesired vibrations are damped by projections carried by springs 17 and adjacent to the holding pins 16. Packing 13 may be provided to steady the crystal during transport, and the assembly is enclosed in a glass tube 1 with water-tight end caps. In a modification, Fig. 7 (Cancelled, not shown), the crystal may have two pairs of electrodes with corresponding terminals, and the spring 24, Fig. 9 (Cancelled), carrying one of the pins 16 that support the crystal, can be adjusted by means of the screw for positioning the crystal. This subject-matter does not appear in the Specification as accepted.

Title: Supply system for a dry-shaver
IPC: B26B19/28
Filed: 1959-01-07
Abstract: 896,141. Charging batteries. LICENTIA PATENT-VERWALTUNGS-G.m.b.H. Jan. 7, 1959 [Feb. 24, 1958], No. 641/59. Class 38 (4). [Also in Group XXXVI] A dry shaver 1 driven by a direct current motor 2 controlled by a switch 3 can be energized either from an alternating current source over rectifiers or from a small re-chargeable battery. An adaptor 5, having pins 6 for connection to an alternating current source, houses rectifiers 9, a resistor 10, switch contacts 11 and socket contacts 12; the dry shaver being provided with similar socket contacts 15. A lead 4 is provided to interconnect the shaver 1 and the adaptor 5, the end 14 of the lead having a plug with a long protuberance fixed thereto whilst the end 13 has a plug with a short protuberance. Due to the provision of the long protuberance the plug end 14 can only be inserted into the shaver socket 15 when the battery 24 is removed from the shaver whereupon the motor 2 is energized from the A.C. source over the rectifiers 9 with the resistor 10 short-circuited by the switch 11. When the battery 24 is housed within the shaver 1 and the lead 4 reversed with the short protuberance plug end 13 inserted into the shaver, the long protuberance end 14 when inserted into the adaptor 5 will open the switch contacts 11, thus inserting resistor 10 in the circuit. Under these conditions the current is reduced so that the motor is incapable of operation but the battery 24 will receive a charge. The battery terminals are so arranged that it is impossible to reverse the polarity of the circuit if the battery is wrongly inserted.

Patent GB-523183-A (GB)
Title: Improvements in or relating to roll film photographic cameras
IPC: G03B19/04
Filed: 1939-01-10
Abstract: 523,183. Photographic roll film cameras. NAGEL, H., and KODAK, Ltd. Jan. 10, 1939, No. 802. [Class 98 (i)] A double-exposure preventing device on a roll-film camera is operated by a pivoted lever which, upon actuation of the shutter release, is moved bodily in its own plane by a cam surface on the release member to disengage one end from a shoulder on a cam disc frictionally driven from the film-winding mechanism, the lever then turning to operate the doubleexposure preventing device; the subsequent operation of the film winding device rotates the cam disc which causes the reverse movements of the lever to render the double-exposure device inoperative. In the form shown in Figs. 2 and 3, a shutter 14 carried by a bell-crank lever 15 is moved to obscure the lens 12 of a direct-vision finder when an exposure has been made, for which purpose a slot in one arm of the lever is engaged by a pin 19 carried by a lever 20 pivoted to one arm of a bell-crank lever 23 and having a ncse 25 engaged by a shoulder on a cam 7 which is rotated through a friction clutch from the film-winding knob. The bell-crank lever 23 has an extension 34 lying in an inclined cam slot in the vertically-movable release button 36. In the positions of the parts shown in full lines an exposure may be made, the view-finder being unobscured. On pressing the shutterrelease button 36 the cam slot acting on the extension 34 of the lever 23 moves this lever to the broken line position, thus carrying the lever 20 to a position in which the nose 25 is released from the shoulder of the cam 7, the lever being thereupon moved anti-clockwise about its pivot by a spring 28. In this position the pin 19 holds the bell-crank lever 15 so that the shutter 12 obscures the view-finder. On winding the film, the cam 7 is rotated until the shoulder 26 is again engaged by the nose 25 of the lever 20, which is urged towards the cam by the spring 28, the parts being then in position for another exposure. In place of the shutter 14 an indicator mounted on any suitable part of the camera may be similarly operated. In the form shown in Fig. 5, on pressing the release button 39 an inclined surface on it engages an arm 41 and moves the lever to the right so disengaging it from a depression 60 in the cam disc, whereupon the lever is turned anti-clockwise by a spring 47. At the same time a lug 59 on the lever releases a pivoted latch 52 which is moved by a spring 53 and engages a slot in the side of the button 39, so latching it against further actuation until rotation of the frictionally-driven cam disc 7 by the film-winding device restores the parts to their original position.

Title: Device for checking short time air-pressure fluctuations in passanger vehicles
Inventor: BARTSCH WOLFGANG
IPC: G01L19/08
Filed: 1991-01-15
Abstract: Increasing travel speeds bring about high pressure surges when trains pass or at tunnel entrances. In order to prevent possible ear discomfort for the passengers, pressurised railway carriages are used whose air tightness however decreases over its service life. As a result, the air pressure surges occur to an increasingly large extent also inside the carriage. In order to identify these effects according to number and strength, and in order to derive economically viable resealing frequencies therefrom, the device according to the invention is used to detect and register brief air pressure fluctuations in a physiologically weighted manner. The localisation of leakage points is also possible. This device operates purely electronically using exclusively commercially available components; it therefore has a high degree of operational reliability, is cost-effective and small in terms of volume.
