Title: Improvements in or relating to control systems for motor vehicles
IPC: F02D29/02
Filed: 1939-09-11
Abstract: 534,691. Variable-speed gearing. DERUNGS, E. A. Sept. 11, 1939, No. 25543. Convention date, Sept. 10. 1938. [Class 80 (ii)] In a control-system for motor vehicles having a variable-speed gear, a fluid-operated retarding-device, which is automatically adjusted in accordance with the setting of the gears, is employed for varying the time occupied in the disengagement and re-engagement of the driving-clutch and in the changing of the gear. A longer time is taken in changing from a lower to a higher gear than vice' versa, in order to avoid shocks and loss of speed. In the arrangement described, the clutch C of the motor A, and a two or more speed gear contained in a box B, are operated by a sliding rod 20, which is moved in one direction by an electromagnet 18 and is controlled by a dashpot 26, the fluid passage of which is varied in size according to the change of gear to be made. The circuit of the magnet 18 is completed by a commutator, which is adjusted by the driver, and also selects the required gear and opens or closes the throttle-valve 2 of the motor. The two-speed gear is operated by two sliding rods 6, 7, to which are pivoted rods 10, 11 connected by a cross-bar 15. The desired gear is selected by one of two electromagnets 12, 13 the circuit of which is made by the commutator. The magnets are carried by a sliding frame 14, which is operated by a lever 22 from the rod 20. The operative magnet attracts the cross-bar 15. which is rocked by the frame 14 and moves one of the rods 6.7 in a direction to change the gear. The clutch is disengaged by a lever 5 connected to the rod 20. The shaft 35 of the throttle-valve 2 is turned in one or other direction by one of two electromagnets 29, 30. the circuit of which is also made by the commutator. To the shaft 35 is connected a rotary valve 53, which is connected by a pipe 52 with the aperture 27 of the dashpot 26. The valve 53 controls a series of openings 58. by which the admission of air to the dashpot is varied. so as to retard more or less the movement of the operating-rod 20. The accelerater-pedal 3 has a yielding connection with the shaft 35 of the throttle-valve, so that the automatic actuation of the valve is independent of the pedal. At the end of the travel of the frame 14, the circuits of the magnets are broken, and the rod 20 is returned to its upper position by spring action. This movement effects the re-engagement of the clutch, the speed of which operation is determined by a second rotary valve 61, which is adjusted by the cross-bar 15 of the gearchanging mechanism. The valve 61 is connected to the dashpot by a pipe 64, and controls the emission of air during the upstroke of the rod 20. A third valve 66 enables the initial resistance of the dashpot to be adjusted by hand.

IPC: C10B7/06
Filed: 1919-10-20
Abstract: 159,246. Gercke, M. Oct. 20, 1919. Carbonizing; retorts.-In the continuous distillation of coal and shale by contact with steam superheated to about 500‹ C., the fuel is preheated before entering the distillation chamber, or coming into contact with the steam. In one form, the preheating is effected in a steamjacketed charging-section B. In a modification, the fuel passes through an oil-bath circulating in the lower part of the distillation chamber A; the oil is maintained at about 150‹ C. by the waste heat from the boiler. The fuel is fed from a hopper G and is conveyed through the apparatus by endless chains E carrying pistons F. The distillation chamber A is formed by double-walled perforated tubes D, and steam from a boiler N and superheater P, at a pressure of from 2¢ to 10 atmospheres, is introduced through a pipe J, escapes through a pipe J<1> into a condensing-vessel K, and is returned to the superheater; the condensation liquor from the lower end of the chamber A also passes into the vessel K. The carbonized product is discharged from a section C.

Title: Linearity correction in electrical transducers
IPC: G01R17/00
Filed: 1975-06-10
Abstract: 1493940 Calibration of voltage measurement systems W & T AVERY Ltd 10 June 1975 [11 June 1974] 25796/74 Heading G1U A transducer output voltage is corrected to provide a desired response, by comparing the actual response deviation with predetermined deviation functions, which are weighted to bring the difference therebetween to zero at particular values of the physical quantity represented by the transducer output. In Fig. 1a, Tl represents the deviation of the transducer output (e.g. a load cell) from a linear response. This deviation is compared with a predetermined function Lo, which by weighting with a suitable factor P brings the difference between Tl and PL o  at O, (Z o ) to zero. Combining Tl and PLO gives a new response T2, Fig. 1b. This is compared to a second function L1 which by suitable weighting Q brings the difference at full load (ZR) to zero. Combination of T2 and QL1 gives a new response T3 which is compared to a weighted function RL2. This process is repeated until the deviation response is suitably accurate. The succeeding weighted functions must have zero value at those values of the physical quantity already used for calibration. Figs. 4, 5 (not shown) illustrate sets offunctions which can be used for calibration at various points in any order, since they each have zero values at all but one of the calibration points. The resulting weighted functions are used to process the transducer output in use, Figs. 2, 3 (not shown).

Title: A process for the production of chemically pure aluminium compounds
IPC: C01F7/56
Filed: 1924-10-31
Abstract: Crude aluminium sulphate, obtained for instance by treating an ore such as bauxite with sulphuric acid, is saturated with hydrochloric acid gas, so that crystals of aluminium chloride separate.  The mother liquor containing hydrochloric and sulphuric acids is concentrated with the addition of previously concentrated sulphuric acid, until the hydrochloric acid gas is expelled.  The sulphuric acid remaining is cooled to separate ferric sulphate and then used again to act upon more raw material.  The Specification as open to inspection under Sect. 91 (3) (a) mentions clays, ampelites or the like as raw materials and states that the aluminium chloride crystals are washed with hydrochloric acid, dissolved in water and precipitated with hydrochloric acid gas, these operations being repeated as often as necessary to obtain a product free from iron. The aluminium chloride may be treated with sulphuric acid or calcined at 300 DEG  C. so as to obtain pure aluminium sulphate or alumina, while the hydrochloric acid evolved in the various operations is used for the precipitation of aluminium chloride or the decomposition of aluminium sulphate, or is absorbed in a saturator.  The wash liquors are treated with the mother liquors to recover the hydrochloric acid with or without the addition of sulphuric acid. This subject-matter does not appear in the Specification as accepted.ALSO:Crude aluminium sulphate solution, obtained for instance from an ore such as bauxite and sulphuric acid, is saturated with hydrochloric acid gas, so that crystals of aluminium chloride separate.
