Title: Nonlinear function generating means
IPC: G06G7/24
Filed: 1960-08-22
Abstract: 901,503. Electric analogue computing. DOUGLAS AIRCRAFT CO. Inc. Aug. 22, 1960 [Aug. 31, 1959], No. 28940/60. Class 37. Non-linear function generating means utilizes stacks of elements with current flow varying exponentially with applied voltage, e.g. silicon carbide. Networks giving square, cube, square roots, cube roots and combination powers are described. Silicon carbide varistor elements V 1 , V 2  . . . V N  are arranged back to back to compensate for semiconductivity, Fig. 8, and are in series with a fixed resistor 15, a thermistor 16 compensating for the varied negative temperature coefficients of the components and a variable resistor 17 to ground, the output e 0  being taken from a sliding contact 19 on the fixed resistor 15 and fed to an amplifier 126 having a feed-back resistor 127. The input of two voltages of equal value but opposite signs is fed into a full-wave rectifier 128 but it may be a single input (Figs. 3, and 6, not shown). Each varistor element has approximately the required square power relationship, adjustment of resistance by the sliding contact 19 giving the correct square power relationship. The circuit of Fig. 10 develops a square root output. The output lead 18 of the squaring unit 135 is connected to the input of computing amplifier 137 whilst the unit 135 is also connected between ground and the output of amplifier 137, the latter being a high-gain high-impedance unit with an output varying inversely with feed-back voltage, i.e. proportional to the square root of the input voltage e i . Inclusion of a diode ensures output only for input voltages of positive value. Similar circuits for cube and cube root outputs are illustrated in Figs. 11, 13 and 15 (not shown). In Fig. 17 a cubing unit 165 with a resistive feed-back of resistor 167 and thermistor 168 across its computing amplifier 166 is coupled to a varistor squaring unit 169 and feed-back amplifier 171 to give an output e o  which is a sixth power of the input e i . Similarly can be obtained any desired integral or non-integral power or root.

Title: Improvements in turntable drive
IPC: G11B19/265
Filed: 1947-11-03
Abstract: 641,736. Toothed gearing; clutches; universal couplings. WESTERN ELECTRIC CO., Inc. Nov. 3, 1947, No. 29276. Convention date, Nov. 13, 1946. [Classes 80(i) and 80(ii)] [Also in Group XXXVIII] A two speed turntable drive comprises a pair of driving shafts each coupled to the turntable shaft through gears and each bearing a hollow pulley which encloses a one-way clutch, the two clutches being adapted to engage in the same direction, and reversible driving means arranged to drive the pulleys in opposite directions. In Fig. 2, a gramophone turntable 14 may be rotated by means of either shaft 27 or 28, through gears 33, 35 and 37. Shafts 27 and 28 are coupled through one-way engaging clutches 30, 31 to pulleys 21 and 22, which are driven in reverse directions by means of belt 20, which is driven by reversible motor 11. Gears 33 and 35 provide different speed ratios, and therefore turntable 14 rotates in the same direction but at different speeds according to whether shaft 27 or 28 is operative, which is dependent upon the direction of rotation of motor 11. A resilient coupling between gear 37 and the turntable shaft is provided by means of metal rings 44 and 48, and a cylindrical member 45 the centre of percussion, of which is at ring 44, and reference is made to U.S.A. Specification 1,832,285. To ensure smooth movement to gear 37, helical gears in conjunction with spring elements 34, 36 and damping plunger 9 are also provided. The turntable spindle 23 may be replaced to accommodate non-standard record discs. The one-way engaging clutch is shown in Fig. 3. A plate 52 carrying gears 53 and 54 is held in light frictional engagement with pulley 22 by means of spring 58, and gear 50 is fixed to shaft 28. If pulley 22 is rotated anti-clockwise, shoes 55 and 56 are urged into contact with pulley 22 so that shaft 28 is driven in the same direction. Clockwise rotation of pulley 22 does not provide this contact so that shaft 28 is left free.

Title: Intermittent electric current interrupter for use with vehicle direction signals
IPC: H01H43/28
Filed: 1925-11-20
Abstract: 266,431. Rayner, G. F., (Winooski Electric Manufacturing Co., Inc.). Nov. 20, 1925. Pneumatic actuation. -The signals are automatically closed to flash by a pneumatic interrupter inserted in the electric circuit and operated by the engine suction. The interrupter comprises a casing 12 mounted on the dashboard C and communicatihg by a duct 25 with the intake manifold. A cover 13 of insulating material is held in place by spring clips 14 and serves to secure a flexible diaphragm 20 normally pressed upwardly by a resilient plate 34 resting on shoulders 33 and having a pair of depending arms 40. A plunger 29 secured to the diaphragm controls a contact 26 co-operating with a contact 27 so that when the diaphragm is in normal condition as shown the circuit containing these contacts is open. An air-vent nipple 37 is adjustably mounted in the base of the casing and constitutes one of two seats for a ball valve 38 the other seat being at the end of the duct 25. When the engine is running, the reduction of pressure in the casing causes the diaphragm to flex downwardly and the contacts engage. The descent of the plate 34, however, by the action of the arms 40 on the ball forces this into its upper position thereby stopping communication with the intake and opening the chamber 21 to atmosphere. The diaphragm thereupon returns to normal, again shifting the ball to restore the previous condition. The frequency of oscillation may be varied by screwing the vent-nipple in or out, a spring washer 44 serving to retain the nipple where set.

Title: Recovery process for gibberellins
IPC: C12P27/00
Filed: 1957-09-20
Abstract: Gibberellins are recovered from a gibberellin-containing filtered fermentation broth, by extracting said broth with a water-immiscible organic solvent of the group consisting of ethyl acetate, methyl ethyl ketone and methyl isobutyl ketone, and then isolating gibberellins from the organic solvent extract.  The extraction may be effected with a continuous extraction type apparatus, such as an extraction tower, a DeLaval centrifugal extractor, a Schiebel column or Podbielniak extractor.  Prior to extraction the pH of the fermented broth as adjusted in the range 2.0 to 3.5 and the extraction effected at 15-75 DEG  C.  The gibberellins are isolated by concentrating the solvent extract until precipitation of the impurities takes place, filtering said impurities, and concentrating the filtrate until crystallization of the gibberellins commenced. Alternatively the gibberellins are isolated by concentrating the organic solvent extract followed by the addition of lead acetate to the resulting concentrate. Examples describe the isolation of gibberellins using the solvents mentioned above.  Specification 783,611 is referred to.
