Title: Readers for punched cards
IPC: G06K7/016
Filed: 1975-02-28
Abstract: 1492116 Punched card reader SOC ITA. LIANA TELECOMUNICAZIONI SIEMENS SpA 28 Feb 1975 [21 March 1974] 8411/75 Heading G4M A punched card reader has a plurality of optical sensors LO arranged transverse to the direction of movement of the card and a plurality of optical sensors LV arranged parallel to the direction of movement of the card. The parallel sensors LV are spaced a distance h, equal to the spacing between columns on the punched card and the spacing h between the sensors LO and the first of the sensors LV is equal to the spacing between the leading edge of the card and the fitst column (Fig. 3, not shown). The card has a leading corner removed so that when a card is inserted into a slot of the reader to obscure the first of the parallel sensors LV an end one of the transverse sensors is not obscured and acts as a control sensors. This sensor is maintained activated in the waiting condition. The vertical sensors feed a NOR gate N, so that each time a sensor is obscured a pulse is fed to activate a counter CN1 which receives timing pulses CK to successively activate, via decoder DC1, transverse sensors LO. Data from each column on the card is fed to memory MM. After all sensors LO have been activated counter CN1 produces a pulse c which increments counter CN2 which, via decoder DC2 activates the next sensor of parallel sensors LV. When all columns have been read Logic Network RL produces a pulse g which clears counter CN2 such that the first sensor is again activated. If a card is fully removed during reading the counters are reset. If a card is partially removed reading does not commence until the activated sensor LV is obscured so that a column is not accidentally read twice.

Title: Piezo electric crystal system
IPC: A47L9/10
Filed: 1930-03-17
Abstract: 350,946. Piezo-electric crystals. HARRISON, J. R., 3134, Avalon Street, Pittsburg, U.S.A. March 17, 1930, No. 8570. Convention date, Oct. 15, 1929. [Class 40 (v).] In order to cause a piezo - electric crystal to oscillate at even harmonics of the fundamental shear frequency, exciting potentials are applied at the faces and the sides of the crystal. In the normal case of the fundamental frequency, the faces of the crystal are oppositely charged at any instant, while for odd harmonics the crystal behaves as if it were composed of superposed crystals, in number equal to the harmonic concerned, so that the upper and lower faces are oppositely charged. At even harmonics, however, the charges are of like sign so that diffculty arises in excitation. This difficulty is obviated by the arrangement shown in Fig. 6, in which the crystal mounting for oscillation at the second harmonic comprises two plate electrodes 22, 24 and. a frame-shaped third electrode 23, of about one-third the thickness of the crystal in the Y axis. The arrangement shown may be varied by connecting electrode 22 to the grid of valve 3, electrode 24 to the anode, and 23 to the filament; alternatively the frame electrode 23 may be in two parts, one being connected to the grid and the other to the valve anode with the electrodes 22, 24 joined to the filament. A crystal mounting for producing the fourth harmonic, Fig. 8, comprises five electrodes ; the frame electrodes 31, 23, 32 are spaced at equidistant points along the crystal, the thickness of each being about one-eighth that of the crystal. Electrodes 22, 23, 24 are connected to the grid and 31, 32 to the filament of the associated valve. More effective generation of odd harmonies may be obtained by the provision of two frame electrodes embracing the crystal at the dotted lines 15, 16, Fig. 4.

Filed: 1919-04-05
Abstract: 176,013. Williams, W. H. April 5, 1919. Mechanical constructions, details for building up.-A constructional toy consists of elements formed of metal strips bent to form girders of T or angle shape, and clamps or shoes of sheet metal with turned-over edges for connecting the ends of such girders together, the girder elements being so made that the flanges spring a little, thus enabling them to be fitted beween the turned-over edge of the clamps or shoes. The element C, Fig. 3, consists of a strip of metal bent, as shown, to form a girder with flanges 10 and a double web 9 with a space 2 between. Thus the flanges can be sprung in between the turnedover edges 19, Fig. 8, of a clamp or shoe 17, where they are retained by friction. The girders can be of various sections, such as the channel section, D Fig. 4. The shoes may also consist of straight strips, or may have a number of arms, or a second arm 21, Fig. 8, may be pivoted to the main shoe 17. The arms of the shoe may be bent at various angles to one another, and the girders may be notched so that they can be bent. Fig. 9 shows a bedstead constructed from the elements.

Abstract: 578,136. Sulphur. UDY, M. J. May 6, 1944, No. 8629. Convention date, Jan. 20. [Class 90] Sulphur is produced by reacting substantially pure hydrogen sulphide and substantially pure sulphur dioxide in an atmosphere of water vapour maintained over a body of aqueous liquid, and at a temperature below the boiling point of water. The temperature of the aqueous liquid is preferably maintained at 50‹-100‹C., by heating or heat-dissipating means. In the apparatus shown, in which the reaction chamber 11 is provided with baffles 13, 14, the gases enter by two inlets at 15, sulphur is deposited on the baffles and the walls of the chamber, and may be continuously removed by mechanical means. Dilute gases are concentrated for use in the process, for example by absorption in liquid which is subsequently heated. The gases may be produced from iron sulphide-bearing material, the sulphur dioxide by roasting the material in air, and the hydrogen sulphide by treatment with acid. U.S.A. Specification 1,941,623 is referred to. In the Specification as open to inspection under Sect. 91, the process is not limited to the use of substantially pure gases, to the provision of a body of aqueous liquid, nor with regard to temperature.

Abstract: 293,110. Holliday & Co., Ltd., L. B., Kitson, J., and Shaw, C. March 30, 1927. Benzoquinone dyes.-By heating with aqueous alkali, chloranil or bromanil is hydrolyzed giving the insoluble alkali 2: 5-dihydroxy-3 : 6-dichlorbenzoquinone or alkali 2 : 5-dihydroxy-3 : 6-dibrombenzoquinone, and a dyestuff dyeing wool and silk brown tints which may be precipitated with acid or by salting out. Products soluble in alkali are also obtained by heating choranil with alkali 2 : 5-dihydroxy-3-6-dichlorbenzoquinone or with alkali 2 : 5-dihydroxy-3 : 6-dibrombenzoquinone. Similar products are obtained starting with bromanil instead of chloranil. By heating with water, alkali 2 : 5-dihydroxy-3 : 6-dichlorbenzoquinone or alkali 2 : 5-dihydroxy-3 : 6-dibrombenzoquinone yields a brown dyestuff which may be precipitated by means of hydrochloric acid. Instead of heating the alkali 2 : 5-dihydroxy-3 : 6-dichlor (or dibrom) benzoquinones alone with water they may be heated with the alkali-free dichlor- or dibromdihydroxybenzoquinones. An example is given in which 2 : 5-dihydroxy-3 : 6-dibrombenzoquinone is boiled with sodium 2 : 5-dihydroxy-3 : 6- dichlorbenzoquinone.

Title: Viscosity comparator

Abstract: 710,029. Viscosimeters. GERIN, F. L. April 7, 1952, No. 8831/52. Class 106 (2) A viscosity comparator of the falling-ball type comprises a number of tubes 16, Fig. 6, one for holding a standard liquid and the others for holding the liquids to be tested, each tube containing a a movable body 17 with a rod-like appendage 18. By means of the 'rods 18, Fig. 1, the balls 17 may initially be raised to identical upper positions 17<SP>1</SP> in their respective tubes and held there by a common holding mechanism 19. This upper, position is i obtained - by adjusting each rod 18 until a disc 21 thereon occupies a position 21<SP>1</SP> in alignment with a zero-mark on a common scale 15 behind the rods 18. In operation, with tube No. 1 containing the standard liquid and tubes Nos. 2, 3 and 4 containing the different liquids to be tested, a knob 42 is handoperated to release the holding effect of a mechanism 19 on the rods 18. All the balls 17, at the same insant, then begin to fall. When the disc 21 on the rod 18 in tube No. 1 has reached some desired mark, such as 60 on the scale 15, the mechanism 19 is again set to hold the rods 18. The position of the other discs 21 on the scale 15 then gives a comparison of the viscosity of the liquid in their associated tubes with that in tube No. 1. In order that the rods 18 may all be subjected to the same frictional effect during their descent, the structure 22, Fig. 2, on which';the tubes 16 are mounted is preferably provided with a stand 48 allowing the structure 22 to be inclined to the vertical. This arrangement causes the rods 18 as shown in Fig. 6 to continually contact an upper guiding means 33, 34 in the mechanism 19 and thus each rod 18 experiences the same frictional resistance. If the tubes 16 are not inclined with the structure 22 but hang free as in Fig. 7 it will be seen that a common frictional resistance is still effected on the rods 18. Alternatively, Fig. 8, to obtain the desired common frictional effect the axis of the upper guiding means 33, 34 may be-simply displaced away from the axis of the tubes 16. The tubes 16 may be surrounded by a container for a heated liquid to bring the liquids in the tubes to a common desired temperature.

Abstract: 422,310. Valve amplifying circuits. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN, Emmasingel, Eindhoven, Holland. March 22, 1934, No. 9023. Convention date, April 7, 1933. [Class 40 (v)] Coupling between the input and output of a high frequency amplifier is reduced by a highfrequency connection from the side of the output impedance remote from the anode to an auxiliary grid so that the part of this connecton which is common with the connection of this grid to the cathode is of low impedance. The arrangement is contrasted with the known arrangement in which the load is connected to the cathode and shunted by the anode-screen capacity in series with the inductance of the lead connecting the screen to the cathode which results in the application of output potentials to the screen. In a modification (Fig. 3, not shown) the inductive coupling between the screen grid and control grid is compensated by returning the anode load impedance to a point intermediate the ends of the screen grid.
