Title: D.c. amplifier assembly with drift correction
IPC: H03F3/387
Filed: 1970-01-22
Abstract: 1299582 Drift corrected amplifier SOC D'ETUDES RECHERCHES ET CONSTRUCTIONS ELECTRONIQUES 22 Jan 1970 [21 May 1969] 3207/70 Heading H3T In a drift compensated amplifier A, the output of a first amplifier stage A1 having a higher gain than a second stage A2, is connected to one input B1 of the second stage comprising a differential amplifier A2 and to a sample and hold circuit A4, C4 recording a drift correction signal, the output of which is fed to the other input B2 of the differential amplifier A2 and a control means T2, T3, T4, T5 periodically switches the input of the amplifier A1 to ground and simultaneously operates the sample and hold circuit A4, C4 to memorize the output of the amplifier A1, the second input of the differential amplifier A2 thereafter receives the memorized signal for drift compensation. The output from stage A2 is fed to an output stage A3. Feedback is fed from resistor network R as controlled by field effect transistors T1, T10, T50, T100 and T1000 to E2 to determine the gain of the main amplifier A. When field effect transistors T0, T2, T6 and one of the field effect transistors T1, T10, T50, T100 and T1000 are conducting a zero drift correction signal is fed via unity voltage gain differential amplifier A5 to the input B2 of the differential amplifier A2. Also capacitor C6 charges to the output voltage at S. Periodically These transistors T0, T2, T6 and T1-T1000 turn off and field effect transistors T3, T4, T5, T7, T8, T9 conduct so that the zero drift correction voltage is sampled and applied via unity voltage gain differential amplifier A4 to be stored on the capacitor C4. Also during these sampling periods the output at S is maintained due to the voltage stored on capacitor C6 which is fed via unity voltage gain differential amplifier A6 and field effect transistors T7, T9 to the output S. The amplifier A may be used to amplify outputs from a thermocouple or strain gauge.

Filed: 1940-02-22
Abstract: 541,402. Purification of oils. NAAMLOOZE VENNOOTSCHAP DE BATAAFSCHE PETROLEUM MAATSCHAPPIJ. Feb. 22, 1940, No. 3322. Convention date, April 3, 1939. Drawings to Specification. [Class 91] Hydrocarbon oils, particularly lubricating oils, are desulphurized by heating to a temperature of 205-370‹ C. with cuprous oxide in quantity to provide at least one mol per mol of mercaptan sulphur in excess of 0.01 per cent. and for a sufficient time to convert any disulphide sulphur into mercaptan sulphur and the whole of the latter then into cuprous sulphide. When disulphides are present, temperatures of about 315‹C. are required. The cuprous oxide employed should contain less than 10 per cent. of cupric oxide to be effective. The refining treatment liberates olefines which are subsequently removed by hydrogenation or treatment with sulphuric acid. The initial oil should be free from asphalt and is preferably a raffinate obtained by extracting a mineral oil with a naphthenic solvent such as liquid sulphur dioxide. An example is given of the treatment of such a raffinate to give a transformer oil. Oils useful as burning oils or in electrical switches or refrigerators may also be obtained. Specification 203,354, [Class 91], is referred to.

Abstract: 980, 795. Selecting record sheets. J. HANDLEY. Jan. 10, 1963 [Jan. 29, 1962], No. 3335/62. Heading G4M. In apparatus for withdrawing a selected record sheet from a stack in which a pair of gripper jaws 28, 29 are movable parallel to a plane containing exposed edges of the sheets in order to select a sheet, the jaws are moved into engagement with the selected sheet by movement of a pneumatic piston 1 which lowers bar 2, slidable in rack bar 20, and jaws 28, 29 until the jaws are in engagement with the sheet. Pin 32, fixed to rack bar 20, then engages the top of slot 31 in a bar 30 which has lugs (not shown) extending on either side of bar 2 and connected by pins 4 passing through slots 24 in bar 2, to prevent further downward movement of the jaws. In the final part of the stroke of piston 1, bar 2 moves relative to bar 30 and its end 8 cams a double-ended lever 9 pivoted at 6 to close jaw 29 against fixed jaw 28 and thereby grip the sheet. The sheet may then be withdrawn from the stock by means of rack 21 and pinion 22. After re-inserting the sheet in the stack by means of the rack and pinion, piston 1 is driven upwards, springs 5 prevent bar 30 rising so that bar 2 moves away from lever 9 and opens the jaws. When the bottom of slots 24 engage pins 4 the bar 30 and jaws 28, 29 are raised together until the rest position, with pin 32 engaging the bottom of slot 31 is reached. Specification 969,323 is referred to.

Filed: 1955-02-08
Abstract: 766,204. Coffee percolators. WESTING- HOUSE ELECTRIC INTERNATIONAL CO. Feb. 8, 1955, No. 3687/55. Class 129 [Also in Groups XI and XXXVII] An electric coffee percolator comprises a vessel 3, a percolating pump, whose pumping chamber 19 is heated by a first heater 29 to operate the pump, a fountain tube 15, whose lower end communicates with the pumping chamber 19 and a second heater 31 remote from the pumping chamber and controlled by a thermostat 33 so that it heats the water contained in the vessel 3 to a predetermined temperature after which it is de-energized and the first heater 29 continues the coffee making operation. As shown, the tube 15 supports a foraminous coffee basket 13 and is mounted on and extends through a valve portion 21 with apertures 23 supported on top of well 19. A valve disc 27 slides on the end of tube 15 within well 19 and is retained thereon by collar 25. As the well 19 is heated by heater 29, which is controlled by a manually adjustable thermostate 35, steam is generated which pushes disc 27 up against apertures 23 and prevents further liquid from entering well 19. As steam pressure increases it forces the water in well 19 up thorugh fountain tube 15 and over basket' 12 until well 19 is empty and the steam is exhausted through tube 15 whereupon disc 27 drops and water flows into the well again. In operation, heaters 29 and 31 are energized simultaneously and percolation commences slowly. Heater 31 heats the liquid in vessel 3 up to 170‹F. rapidly and is then cut off. Percolation accelerates at about 160‹F. and after heater 31 has been cut off, heater 29 continues percolation until the brew has reached a temperature of 180‹F. to 200‹F. according to the setting of thermostat 35. After heater 29 is de-energized the percolater will cool to 170‹F. and be maintained at this temperature by heater 31 and thermostat 35. Thermostat 35 will not reset itself until the temperature has dropped to 100‹F. The higher the temperature for which thermostat 35 is set the stronger will be the coffee produced. Thermostat 33 may incorporate a compensating arrangement to control the infusion period more accurately when varying amounts of coffee are made in the percolator.
