Title: Electrode for medical purposes, particularly for use in diathermic treatment and process for the production thereof
IPC: A61N1/04
Filed: 1926-05-03
Abstract: 261,335. Last, E. Nov. 14, 1925, [Convention date]. Electric appliances.- An electrode for di,athermis or other medical treatment consists of a non-conducting carrier moulded from a material sufficiently pliable during moulding to adapt itself accurately to the curvatures of the treated part of the body and having an electrically - conducting lining connected to the current source. The face electrode shown complete in Fig. 1 and in section in Fig. 2 is made up of forehead, nose, and chin elements 10, 15, 25, Fig. 8, of backing material moulded to the face and lined, after setting, with tin or other metal foil 3, Figs. 1 and 2, turned over at the edges of the backing and secured by strips of sticking-plaster 4. A plate of foil 5 in electrical connection with the lining 3 is attached to the supply at 6. The backing strips are made of suitable fabric, for example several layers of surgical starched gauze, moistened in hot water and secured by a paste of plaster of Paris. The face of the patient is protected by vaseline and the strips are successively applied and manipulated until they adopt the configuration of the face. Plaster of Paris is applied to hold each strip in the form to which it is moulded. The strip 10 is slit at 11, 12 to adapt it to the curvature of the forehead and the nose strip 15 is slit and turned back at 20, 18, 23, 24 to give openings for the eyes and permit the nose position to be moulded. After the chin strip has been moulded to the face, the three strips being meanwhile held in position by an assistant to the moulder, the three strips are secured together by a strip of moistened starch gauze which is passed from one temple across the chin to the other temple and back again and is secured by plaster of Paris. The mash is left to set for about 25 minutes on the patient's face and is finally dried on a hot metal plate. In use, the electrode is applied to the body, with an intervening ointment, and a gradually increasing trial current is applied. If the fitting is bad at any point, a pricking sensation is felt there and the fit it rectified by raising the foil lining at such points and inserting a wadding, as shown at 7, Fig. 2. Thereafter the full current may be employed.

Title: Logic circuits which employ transistors
IPC: H03K19/018
Filed: 1964-03-19
Abstract: 1,060,542. Transistor logic circuits. RADIO CORPORATION OF AMERICA. March 19, 1964 [April 1, 1963], No. 11737/64. Heading H3T. In a logic circuit, one transistor is coupled to a further transistor by means of at least one level shifting diode having a diffusion capacitance that varies as a function of current. Fig. 1 shows part of a logic circuit in which a gold-doped silicon epitaxial transistor 50 has three diodes 56 forming part of the collector region and is coupled via level shifting silicon diodes 38, 40 to a similar transistor 20. Transistor 50 is saturated by a positive logic signal at its base so that the voltage at node 42 cuts off diodes 38, 40 and transistor 20. When a negative logic signal is received by the base of transistor 50 this transistor is cut off so that the voltage at node 42 turns on diodes 38, 40 and transistor 20. The switching times are reduced by the action of the current-dependent capacitance of diodes 38, 40. The Specification explains how diodes 38, 40, 56 minimize reflections in the transmission line 54 and provide a degree of noise immunity. The bias current supplied by source 48 should be a specified function of the characteristic impedance of the transmission line 54. Fig. 3 (see Division H1) relates to the construction of transistor 50 and diodes 56 on a single chip of silicon. Figs. 6, 7 (not shown), relate to NOR circuits in which the outputs of three circuits of the type shown in Fig. 1 are fed to the input of a fourth circuit.

Patent GB-1487908-A (GB)
Title: Timepiece
IPC: G04B19/22
Filed: 1976-03-25
Abstract: 1487908 Watches EBAUCHES SA 25 March 1976 [10 April 1975] 11951/76 Heading G3T In a timepiece having a minute indicator 1 on a cannon pinion 2, and an hour indicator 6 which is adjustable in one hour steps when changing time zones, in order to avoid displacement of the minute hand 1 during such adjustment a locking member 30 is coupled to the adjusting mechanism momentarily to lock the cannon pinion, and a resilient coupling is provided in the drive to the cannon pinion to yield when the pinion is so locked, the coupling acting, when the pinion is released, to move the minute hand to the position it would have occupied if it had not been restrained during the adjustment of the hour hand 1. The resilient coupling yields at a torque below that transmitted by the usual friction clutch (not shown) provided in the drive to the cannon pinion to permit conventional hand setting. As described the coupling comprises an arcuate wire spring 35 with its ends 35a bent at right angles into elongated slots 33, 34 formed respectively in a centre wheel 31, which is freely mounted on the cannon pinion 2, and a disc 32 which is forced on that pinion. The hour hand 6 is attached to a wheel arid arbor 5 with a star 7. The star is coupled to hour wheel 4, which may bear a conventional hour hand, by an annular spring 8 attached to the hour wheel at 9. The star has twelve teeth and the torque needed for it to slip under the spring 8 during adjustment is greater than the yield torque of the resilient coupling. The watch has a stem 10 coupled to a pull-out piece 17 and a lever 13 which is pivoted at 14. With the stem pushed in as shown, a wheel 12 mounted on the lever couples clutch pinion 11 on the stem to a pinion 24. The latter is attached to a shaft 25 which carries a member 28 with two sets of teeth 28b and a cam 29 which acts on one arm of bifurcated locking spring 30. When the stem is turned, the teeth 28b are rotated into intermittent engagement with the wheel 5 to rotate it in one hour steps and, at the same instants, the cam 29 brings teeth 30b on the other arm of the spring 30 into locking engagement with the hour wheel 4. The cannon pinion is thus also locked but the centre wheel 31 continues to rotate, flexing the spring 35. When the stem is released, the spring 30 returns the parts to the position shown and the spring 35 moves the cannon pinion and minute hand to their correct position. If the stem is pulled out to an intermediate position, the wheel 12 is displaced to bring calendar correction toothing 21 thereon into mesh with a date ring 22. When the stem is fully pulled out, the wheel 12 meshes with an idler 23 which meshes with the hour wheel 4 for conventional correction of the hands.
