Title: Improvements in and relating to oscillographs
IPC: G01R13/26
Filed: 1944-09-19
Abstract: 580,236. Oscillographs. MULLARD RADIO VALVE CO., Ltd., and SMART, L. D. Sept. 19, 1944, No. 17886. [Class 37] An oscillograph adapted to produce at least two traces on the screen is arranged so that the intensity of at least one of the traces is periodically varied along the trace. The frequency of variation of intensity is large compared with the repetition frequency of the trace and is preferably an integral multiple of it, as that a stable pattern is obtained. If more than two traces are used the periodic variation may be different for each of the traces which are to be distinguished from each other. In Fig. 1, a cathode-ray tube 10 has a grid 16, deflector plates 17, 18 and 8, 9, a cathode 13 and two anodes 11 and 14 supplied with suitable positive potentials at terminals 12 and 15. Deflector plates 17 and 18 are supplied with suitable potentials from time base 19, while deflector plate 9 is connected to the second anode 11. The voltages corresponding to the waveforms to be examined are applied between terminals' 1, 3 and 2, 3 respectively, and terminals 1, 2 are connected in turn to deflector plate 8 by way of commutator arm 5 and segments 6, 7 respectively. Motor 4 drives commutator arms 5 and 20, the latter making contact with segment 21 at the same instant that arm 5 makes contact with segment 6. Arm 20 is connected to slider 22 of a potentiometer 23 connected between terminal 3, and a terminal 24 supplied with a suitable negative potential. Condenser 25 maintains a steady voltage between slider 22 and terminal 3. When the arm 20 is making contact with segment 21 a steady negative voltage is applied to the grid 16, and the intensity of the trace is adjusted by means of slider 22. When arm 20 is not in contact with segment 21, the grid 16 is free to take up the steady negative voltage applied by means of resistance 28, slider 27 and potentiometer 26, together with an alternating potential obtained via condenser 29 from a multivibrator 35 of normal type. A synchronising voltage from time base 19 is applied to the suppressor grid of valve 31 by means of resistance 33 and condenser 34. By suitable adjustment of slider 27 the trace corresponding to the voltage applied to terminals 2, 3 can be obtained as a series of dots, and by suitably adjusting the multivibrator a variety of dots can be obtained in order to identify a number of waveforms. In a modification, an electronic switch may be used to apply the voltages to be studied to the deflection plates in turn ; and the multivibrator is blocked, while one of these voltages is being applied, by the voltage generated by the electronic switch. The invention may be applied to oscillographs emoloying multiple electron beams by rapidly deflecting at least one of the beams off the screen at suitable intervals, and can also be applied to oscillographs of the Duddell type by suitable arrangements of shutters.

Title: Improvements in automatic lathes
IPC: B23B7/04
Filed: 1937-06-30
Abstract: 503,216. Lathes. HAHN, H., HAHN. O., and TESSKY, K., (trading as INDEX-WERKE HAHN & KOLB). June 30, 1937, No. 18134. Void. Convention date, July 4,1936. [Class 83 (iii)] A single spindle automatic turret lathe of the " Index " type has main and auxiliary camshafts, the latter being arranged, in the usual manner, to give high speed operation to certain parts of the machine such as the stock-stop, the turret, indexing mechanism and the workgripping gear; the main camshaft is also arranged to have high speed movements during parts of its revolution when the main cam profiles are effecting idle movement of the machine parts. The auxiliary camshaft 3, Fig. 1, is connected by gearing at the right-hand end of the machine, which includes pick-off gears, with a shaft 12 which effects, through worm gearing 13, 19, slow speed rotation respectively to the parts 15, 21 of the main cam-shaft. Dogs 32 on the main cam drum 33, Fig. 3, operate a lever 29, a pin 27 on the end of which engages a groove 30 in a spring-pressed clutch member 25 slidable on the shaft 22. On release of the pin 27 from the groove 30 the clutch member 25 is thrown by the spring into engagement with a clutch member 24 rotating with the shaft 22 but retains its engagement with the member 35 a cam groove of which moves a spring-cushioned rod 37, Fig. 5, to throw a further clutch part 40 into engagement with the rotating clutch part 24. The part 40 is keyed to a gear wheel 39, Fig. 3, and thus through a train of wheels 39-42 the shaft 12 and the main cam shaft 15 is rotated at relatively high speed until the clutch part 25 is withdrawn from the rotating part 24 by the action of the pin 27 in the groove 30. An over-running device 43 enables this drive to operate with the slow speed drive in engagement. In a modification, the over-running device is dispensed with and the high and slow feed drives are obtained through clutch mechanism similar to the above.

Filed: 1964-05-01
Abstract: 1,059,939. Typewriters. OLYMPIA WERKE A.G. May 1, 1964 [May 2, 1963], No. 18194/64. Heading B6F. A typewriter wherein each type bar 6 is connected by links 3 . . . 5 to an operating lever 2 and depression of a key 10 causes release of a pawl 7 on the corresponding lever 2 for engagement with a toothed driving-shaft 11, the pawls 7 have inclined surfaces 7d engaging screws 12 or 13, according to the shift position, to release pawls from the shaft 11, and the inclination of the surfaces 7d is such that if an overall adjustment of the screws 12, 13 is effected as described below, the impact of the type bars remains proportional to the surface areas of their type faces. The screws 12, 13 are carried on a member 14 pivoted at 14a to a lever 15 pivoted to the frame at 17, and are shown in non-shift position. The member 14 is connected by a linkage 20, 21, 25 to a shaft 24 which is rotated clockwise when case-shift is effected thus causing the member 14 to be turned anti-clockwise so that the screws 13 become operative. The lever 15 is mounted on an eccentric 16a which can be turned by means of a hand-lever 18 through gearing 18a, 19 so as to move the lever 15 about the pivot 17 and adjust the screws 12, 13 as a whole relative to the surfaces 7d. An extension 15b of the lever 15 is connected by a link 22 to the pivotal point 20a of the links 20, 21 so that an additional counter-clockwise pivotal movement is imparted to the member 14 when the lever 15 is adjusted. To limit the number of pawls 7 having differently-inclined surfaces 7d, the pawls for groups of type-bars having approximately the same type-face area may be identical, the surfaces 7d thereon corresponding to the mean of the areas. Depression of a key 10 moves a pawl-retaining catch 9 pivoted on a lever 2 away from the pawl 7 so that the latter moves under the action of a spring 8 into engagement with the shaft 11. When the surface 7d of the driven pawl abuts against a screw 12 or 13, the pawl is turned anti-clockwise and is re-engaged by its catch 9.

Title: Method and apparatus for regulating the length of the goods on knitting machines
IPC: D04B15/38
Filed: 1968-04-18
Abstract: 1,205,118. Knitting-machines. SCHUBERT & SALZER MASCHINENFABRIK A.G. 18 April, 1968 [19 April, 1967], No. 18335/68. Heading D1C. In a method of ensuring that goods knitted on different machines, or divisions of one machine, are of equal length, the length of the goods is monitored and compared with a standard so that the loop size may be adjusted automatically. The standard may be the length being knitted on a reference 'division or machine, or the average of lengths monitored or may be prerecorded on a tape. The comparison may be made electrically or mechanically. Straight-bar machines. Fabrics are drawn off over independently rotatable rollers and the extent of their rotation is measured and deviations from the standard used to adjust the loop length during knitting. The press lever 10 is adjusted relative to the regulating lever (301 Fig. 1 not shown) on the quality control shaft by a stop 20, movable by a threaded rod 101, rotated by pawls 104-5 or by a motor. In one embodiment rotation of the rollers adjusts a potentiometer which is arranged in a bridge circuit for comparison with the potentiometer of a reference division, or the average of all potentiometers in monitored divisions. Alternatively pulses derived from rotation of the roller, or a wheel engaging the fabric, are compared with a standard series of pulses in a differential counter and the output used to control take down. Flat-bed machines. In a further embodiment planet wheels (310, Figs. 12-3 not shown) journalled on a carrier (32) are arranged between a gear (3) on each roller and a sun gear (311) driven from the reference division. Rotation of the rollers differing from the standard causes the carrier to operate electromagnets (321', 322') and adjust the quality. Circular machines. The take down rollers periodically close a switch, producing a series of pulses which are fed with a standard series to a differential counter. The stitch length is adjusted by raising or lowering the dial. Alternatively the height of the stitch cams may be adjusted by a driven gear ring (162, Fig. 17 not shown) engaging the cam blocks (16). In another embodiment (Fig. 16, not shown) the knitted fabric is drawn upwards through a double cylinder machine by a clamp joined by a chain to a weight. The chain is guided over pulleys, the rotation of one of which can be monitored. The height of a needle cylinder, supported on rods (171 Fig. 18 not shown) is determined by a lever (143) acting on a pivoted member (149) supporting the rods. The height at any particular stage of knitting is determined by one of several levers (140) acting on the lever (143) and whose positions are determined by set screws (141). The levers (140) are selected by cams (18). The position of the set screws are adjusted depending on the knitted length. The lever (143) is mounted on an eccentric pivot (146) continuously adjusted during knitting.

Title: Foam product and method for manufacture of same
IPC: C01F7/02
Filed: 1966-04-27
Abstract: A foamed structure is prepared by mixing partially polymerized furfuryl alcohol with urethane forming compounds prior to the foaming process, forming a cellular structure by interaction of the urethane compounds, heating the resulting foamed structure to a temperature below the decomposition temperature of the urethane to cure the furfuryl alcohol (about 250 DEG  C.) and then heating first to decompose the urethane (about 450 DEG  C.) and then under nitrogen to carbonize (about 1000 DEG  C.) Metals, non-metals, inorganic oxides or graphite may be mixed into the furfuryl alcohol initially incorporated in the foam.  After the carbonization the temperature may be raised further to form carbides (or graphite).  Inorganic oxides may be formed by carrying out the final heating in air as opposed to nitrogen.  The carbides of tungsten, niobium, tantalum, aluminium, boron and silicon are mentioned, also silica, silicon and aluminium oxide.
