Title: Improvements in clutch control mechanism
IPC: B60K23/02
Filed: 1932-11-26
Abstract: 405,775. Operating clutches. BENDIX AVIATION CORPORATION, 105, West Adams Street, Chicago, U.S.A. Nov. 26, 1932, No. 33528. Convention date, Nov. 27, 1931. [Class 80 (ii).] In a clutch control mechanism for motor vehicles, the rate of engagement of the clutch is controlled by the vacuum generated in the induction pipe. When the engine is idling, the servo-cylinder 12 is in communication with the induction pipe through port 30, the waist of valve 26, port 28, and pipo 18; the piston 14 is thus drawn up, and, by the rope 16 connected to the clutch pedal, holds the clutch in disengaged position. When the accelerator pedal is depressed, the first part of its movement closes a switch, which operates a solenoid 34, which pulls the valve 26 to the right, thus closing the port 28 and opening the cylinder 12 to atmosphere through ports 30, 32. The piston 14 moves rapidly towards the clutch engaging position under the action of the clutch spring until the piston rod 64 enters the port 60 and prevents efflux of air from the cylinder except by the pipe 58. The last part of the movement of the piston is thus controlled by the valve 48, which, when the throttle is closed, is held by the suction from pipe 18 in the completely closed position shown in the Fig., but moves to the right under the action of a spring 68 so as to uncover the port 56 and an increasing number of bleed-holes 54 as the throttle is opened and the suction in the induction pipe consequently diminished. Specification 388,569 is referred to.

Title: A process for the recovery of tungstic catalysts
IPC: B01J23/30
Filed: 1962-08-31
Abstract: Glycidol, prepared by the oxidation of alkyl alcohol with H2O2 in the presence of sodium tungstate as catalyst, may be hydrolysed to glycerol by tungstic acid produced by treating the whole reaction mixture with a cation-exchange resin in its acid form.ALSO:Tungstic acid is recovered from a reaction mixture, resulting from the oxidation of an organic compound with hydrogen peroxide using tungstic acid or a tungstate as catalyst, by bringing the mixture into contact with a strongly acidic polymeric cation exchange resin in its acid form, heating the resulting mixture to precipitate the tungstic acid and separating the tungstic acid therefrom.  Specified tungstates are sodium tungstate, sodium hydrogen tungstate and ammonium paratungstate and specified resins are sulphonated copolymers of styrene and divinyl benzene, sulphonated condensates of formaldehyde and phenolic derivatives and sulphonated copolymers of styrene and methacrylic derivatives. The tungstate solution at a temperature within 100 DEG  C. above ambient temperature may be brought into contact with the resin by passage through a fixed bed. Subsequent heating may be under pressure to temperatures above 100 DEG  C. and any unprecipitated tungstic acid may be extracted by adsorption on activated alumina. If allyl alcohol is oxidized to glycidol by H2O2 in the presence of sodium tungstate, the acid generated by reacting the latter with an ion exchange resin will hydrolyse the glycidol to glycerol during subsequent heating.

Title: Analogue-to-Digital Converter for Wide Band Signals
IPC: H03M1/00
Filed: 1967-07-28
Abstract: 1,159,854. A/D converters. INTERNATIONAL STANDARD ELECTRIC CORP. 28 July, 1967 [30 Aug., 1966], No. 34813/67. Heading G4H. An analog to digital converter, of the type in which samples of an analog signal ec (Fig. 2) are sequentially fed to comparator circuits M1-Mm under the control of a sampling selector C3 and compared with a reference sawtooth waveform Z, coincidence signals being generated when the amplitudes of the analog samples are equal to the sawtooth signal, includes a binary coding counter C2, the state of which represents the instantaneous amplitude of the reference signal, the count in the counter being read into a line in a memory MR when a coincidence signal from the associated comparator occurs. In the embodiment described the coding counter controls by a decoder D the rise and fall times of the sawtooth signal Z. Each of the comparator circuits M1-Mm is enabled during one of m time intervals S1-Sm so that a capacitor in each circuit, e.g. capacitor SH (Fig. 4) in circuit Mj is charged to the value of the associated input sample. Although coincidence may occur between the sawtooth signal and the input signal whilst the capacitor is charging up, no enabling signal is then fed to the memory since it is blocked at AND gate P3 by the signal Sj. If the jth sample of the input signal ec is greater than the value of the sawtooth signal at the end of time intervals Sj, a coincidence signal occurs during one of the subsequent time intervals S and the count in counter C2 is then transferred into line j of memory MR and read out to a register RS during the time interval Sj of the next cycle of the sawtooth waveform. If the sample is less than the value of the sawtooth signal at the end of a time interval Sj no count is transferred to the memory until one of the time intervals Sm ... Sj -1  of the next cycle of sawtooth waveform Z (only Sm -1  samples being read in for each cycle). A coincidence signal from the jth comparator then occurs, the count in counter C2 being transferred to the line j of memory MR and read out during the time interval Sj of that cycle.
