Title: Improvements in or relating to electrical counting devices
Inventor: DAUGUET ALEXANDRE
IPC: H03K21/00
Filed: 1957-12-17
Abstract: 852,479. Electronic counting apparatus. LABORATOIRES D'ELECTRONIQUE ET DE APPLIQUEES L.E.P. Dec. 17, 1957, No. 39204/57. Class 106 (1). In an electric decimal counter or accumulator in which each decade comprises four cascadeconnected bi-stable elements, a correcting impulse corresponding to a count of six is applied to two of the elements when a predetermined pair of elements are in a unique condition immediately succeeding the count of nine. As shown, counting pulses i are applied to the first of cascade-connected elements BI-BIV each comprising e.g. a pair of thermionic valves or transistors. Outputs from the elements are connected via high resistances R1, R2, R3, R4 whose values are in the ratio 8: 4: 2: 1 to a milliammeter M graduated to indicate the registered decimal digit. In the initial or zero condition, element BII is in the "1" state and the remaining elements are in the " 0 " state; the elements are actuated in normal binary fashion until the 10th pulse i is received, when elements BIII, BIV are both switched to the " 1 " state and gate G allows a pulse il from a source S to be applied to elements BII, BIII so as to reset the elements to zero, the pulse being applied also to the first element BI<SP>1</SP> of the next higher decade. This decade also can receive counting pulses, the pulses i and i<SP>1</SP> being interlaced with one another, and includes a further gate (G<SP>1</SP>) also connected to the source S. Counting cycles in which the elements BI-BIV have different initial conditions are described.

Title: Regulating device for reversing curretnt converters
IPC: H02M7/162
Filed: 1971-08-23
Abstract: 1338818 Automatic control of speed and current LICENTIA PATENT-VERWALTUNGS GmbH 23 Aug 1971 [28 Aug 1970] 3946/71 Heading G3R A system for regulating the current in a reversing converter includes an additional regulator with an integrating device, the operation of which is suppressed during converter switching intervals. In the system shown, a D.C. shunt motor M can be reversibly energized by way of one or other of two rectifier groups 1, 2. A tachogenerator T produces a signal n indicative of the actual motor speed and this is compared with a reference signal n s . The resulting error signal is passed through parallel proportional and integrating circuits 3a, 3b to form a reference signal I AS  of appropriate polarity for comparison with an actual current signal I A . The resultant signal is input to a current regulator 4 which supplies a pulse generator 5 controlling the firing of the rectifiers 1, 2. A logic circuit 6 controls the setting of switches 7, 8, 12, 13 at zero current and blocks the regulator 4 for a safety interval before reversing the motor energization. During this interval, the integrating circuit 3b is disconnected by an electronic switch S to prevent build up of a large error signal. The switch S is reclosed at the same time as firing pulses are restarted. Switch 13 is preceded by an inverting amplifier 11 to produce the correct polarity signal for the regulator 4.

Title: Apparatus for Indicating the Position of Out-of-Balance Forces in Vehicle Wheels
IPC: G01M1/28
Filed: 1967-08-29
Abstract: 1,192,185. Measuring vibration electrically. REPCO RESEARCH PTY Ltd. Aug. 29, 1967 [Sept. 1, 1966], No. 39500/67. Heading G1N. The positions of out of balance forces in vehicle wheels are indicated by producing a series of pneumatic pulses in accordance with vibrations produced by the out of balance forces as the wheel is rotated, converting the pneumatic pulses into a series of electrical pulses having a repetition rate according to the repetition rate of the pneumatic pulses, converting the series of electrical pulses into electrical pulses having amplitudes related to the repetition rate of the series of electrical pulses and utilising the amplitude related pulses to operate a stroboscopic flash circuit. A vehicle wheel is initially caused to rotate at a frequency greater than its resonant frequency by contact with a spinner, Fig. 1 (not shown) and then allowed to slow down freely during which time its vibrations are sensed by a vibration pick up, Fig. 2 (not shown) comprising an air bellows and adapted to be placed under the vehicle body or suspension. At a frequency of rotation of the wheel equal to its resonant frequency a mark on the wheel is illuminated by a stroboscopic lamp and its position recorded. The wheel is then rotated in the opposite direction and the observed position of the mark is again recorded, the mean position indicating the position of deflection which is displaced in phase by 90 degrees from the position of the out of balance force at the resonant frequency. The stroboscopic flash circuit is, in accordance with the invention, operated from the instant the speed of rotation of the wheel slows down to the resonant frequency of the wheel. To this end the vibration prick up is connected to an electric -transducer which converts the pneumatic pulsations into a sinusoidal electrical signal which are amplified at 22, Fig. 4. The amplified signals are converted into pulses of constant amplitude occurring in synchronism with a particular point of the waveform of the sinusoidal signal by circuit 23. Saw tooth wave generator 24 produces saw tooth waves from the constant amplitude pulses, the saw tooth wave's amplitude decreasing as the pulse repetition rate increases . Differentiating circuit 28 produces pulses from the saw tooth wave pulses having amplitudes which increase in amplitude as the repetition rate of the pulses decreases and transistor 31 is biased so that only pulses of a certain amplitude are transmitted i.e. corresponding to the speed of rotation of wheel at the resonant frequency. These latter pulses energize the stroboscopic flash circuit 32 to energize the stroboscope and illuminate the mark on the wheel. A meter circuit, Fig. 5 (not shown) for giving an indication of the magnitude of the out of balance force at the resonant frequency may be connected to circuit 22.

Filed: 1958-12-17
Abstract: Mono-olefins are obtained by the selective hydrogenation of conjugated diolefins by contacting with a solution containing [Co(CN)5]3- ions in the presence of hydrogen.  In the hydrogenation of butadiene the use of a CN- to Co molar ratio about 5 : 1 yields mostly transbutene-2 while a ratio of about 10 : 1 gives mostly butene-1.  The ratio is preferably at least 5 : 1 in any event.  The solution may be aqueous or a mixture of water and methanol or glycerol.  The solution is preferably contacted with hydrogen before the reaction; in a preferred continuous process the solution descends two columns in countercurrent to gases, hydrogen only being supplied to the first and hydrogen and conjugated olefine to the second, the solution then being recycled.  If the conjugated olefine is liquid it may be shaken with the solution in a hydrogen atmosphere.  Suitable conditions are 0 DEG C.-100 DEG C. and up to 100 atmospheres.
