Title: Analog-to-digital converter
IPC: G09G3/04
Filed: 1959-12-04
Abstract: 869,406. Electric selective signalling systems. ELECTRONIC ASSOCIATES Inc. Dec. 4, 1959 [Dec. 5, 1958], No. 41282/59. Class 40 (1). An analogue-to-digital conversion system includes a plurality of counters for generating an amplitude significant electrical reference signal responsive to their count, circuit means for continuously comparing an amplitude significant electrical input signal of unknown value with the reference signal and for supplying an output signal indicative of a difference between the values thereof, each of said plurality of counters corresponding respectively to one of a plurality of digits in a number, the final value of which corresponds to the value of the input signal and programming means operatively connected to said comparing means and to said counters to vary the amplitude of the reference signal according to a predetermined programme in dependence upon the output signals from said comparing means and for producing an initial condition of the reference signal by initially setting that one of saidcounters which corresponds to the most significant digit in the number to a minimum count and for initially setting the remaining counters which correspond to less significant digits in the number to a maximum count. As described, a digitalvoltmeter providing a visual output has a measuring cycle of five steps controlled by a programmer device, Fig. 1. In the first step the indicator storage register is cleared and the polarity of the unknown analogue voltage to be measured is determined and stored (but not indicated) in the indicator unit. In the second step the input voltage is compared with 09.99 volts produced by a four-decimal denomination counter and an array of diodes and resistors. If this voltage is lower than the input voltage then the programmer applies pulses to the 1000's counter giving voltages of 19.99, 29.99, 39.99 and so on until the input voltage is just exceeded. Step three then commences and at its beginning the 100's counter is reset to zero giving a voltage of x0.99 (where x is the number of pulses applied in step two). This voltage will (in general) be less than the input voltage and the programmer applies pulses to the 100's counter giving voltages of x1.99, x2.99, x3.99 and so on until the input is once again exceeded. Step four then commences and is similar to step three except that it is concerned with the 10's counter which is initially reset and then counted up until the input voltage is exceeded. This is followed by step five which also is similar to step three and at the end of step five the programmer causes the indicator to become operative. The whole cycle is said to take about one-twentieth of a second. Detailed circuits, employing conventional transistor techniques, are given.

Abstract: 1355565 Organic phosphines and complexes thereof; oxo process BADISCHE ANILIN- & SODA-FABRIK AG 7 Sept 1971 [8 Sept 1970] 41633/71 Headings C2P and C2C The invention comprises compounds of Formula I where R is hydrogen or C 1-12  alkyl and n is 8 to 14. Compounds of Formula I in which R is hydrogen may be prepared by reacting dimethyl phosphine with a suitable omega-alkenoic acid under free radical conditions. Compounds of Formula I in which R is alkyl may be prepared by reacting the corresponding compound in which R is hydrogen with a C 1-4  alkanol and optionally transesterifying with a C 5-12  alkanol, or by reacting phosphine with an omega-alkenoic acid under free radical conditions, esterifying the product with a C 1-4  alkanol, reacting this product, after isolation by distillation, with methyl iodide or methyl bromide, reacting the quaternary phosphine formed with alcoholic alkali solution and optionally transesterifying with a C 5-12  alkanol. The compounds of Formula I may be reacted with metal carbonyl complexes, especially cobalt and rhodium carbonyl complexes, to modify them by replacement of one or more carbonyl ligands by phosphine ligands. The modified metal carbonyl complexes may be used as catalysts in carrying out the oxo process. In a comparative example, a cobalt carbonyl complex modified with trioctylphosphines is used as catalyst in an oxo process in which alcohols are made by hydroformylating a mixture of C 8-10  olefins.

Pawl (42a) at a preset angle to pawl (42b) engages projections 31X, 31Y on clutch plate 31 rotatably mounted on shaft 21. Slow pulling - out of the belt causes slow rotation of inertia disk 36, ratchet wheel 35 and shaft 21. Fast pulling - out of the belt causes inertia disk 36 to lag behind the rotation of ratchet wheel 35 which wheel then moves along external thread 33a on member 33 fixed to shaft 21 and along pins 36a on inertia disk 36 to engage teeth 31a on clutch plate 31 against the bias of spring 34. Clutch plate 31 then turns, projection 31Y pushing pawl (42a) and hence pawl (42b) engages ratchet wheel 24. In Fig. 4 vehicle deceleration or inclination moves member 51 relative to holder 52 to push up rod 53 to brake inertia disk 36, making the engagement of clutch plate 31 and ratchet wheel 35 more sensitive. Friction material may be applied to disk 36 and rod 53. In Fig. 7 (not shown) movement of member (62) relative to holder (63) pushes member (61) which is connected to pawl (42a) to push it into engagement with ratchet wheel 24.

Nov. 13, 1962 [Nov. 24, 1961], No. 42841/62. Heading G4R. In a reading device for a record bearing rows of characters preceded by a "start" mark and followed by an "end" mark, the marks and characters are sensed and the signals used to control a timing device in such a manner that if the sensing unit fails to produce character signals at predetermined intervals after the start mark has been sensed an error signal is generated. The signals from senser A are amplified at L and applied to three triggers O, S and T, the first responding to the start mark, the second to the end mark and the third L repeats the character and mark signals. The trigger O sets a trigger B controlling the repeater T to allow the signals to be transmitted after the start mark is sensed. Signals from triggers B and T both start or restart a timer K set to give an output after one and a half times the normal interval between characters. If a character is missed the timer output passes via gate E1, enabled by trigger B, an error indicator F giving an error indication on line M and resetting the trigger B to prevent further characters being transmitted. The end mark causes trigger S to reset trigger B and also opens a gate E2 so that if the trigger has not been properly set by the start mark the end mark signals an error via unit F. In a modification the start and end marks are detected by the same unit and are applied to a scale of two counter which controls the trigger B, the start and end marks setting and resetting the trigger as before.
