Title: Executing data processing instructions
IPC: G06F7/00
Filed: 1976-05-10
Abstract: 1529638 Data processing TELEFONAKTIEBOLAGET LM ERICSSON 10 May 1976 [14 May 1975] 19189/76 Heading G4A In a data processing system comprising a number of functional units FU to execute instructions and a central instruction store all interconnected by common instruction and data buses, the instructions, accessed from the store in successive read phase times, are of two types, the first having an address part specifying a functional unit and an operational part specifying an operation to be performed by that unit in the read phase following that in which the instruction was accessed, and the second having two address parts specifying functional units to transmit and receive data respectively via the common data bus during the read phase following that in which the instruction was accessed and an operational part specifying an operation to be performed by the data receiving functional unit. The address part of a first type instruction received over bus AB1 activates decoder ADEC1 in the specified unit while the operational part received over bus OB is decoded, ODEC, to activate the appropriate one of the lines 01. Near the end of the read phase in which the instruction was accessed, the read phases being delineated by pulses #p, a pulse #e occurs and the appropriate gate G1 conducts to activate the corresponding element E 1 to cause the operation to be performed by logic L in the following read phase. The first address part of a second type instruction activates decoder ADEC1 in the specified (transmitting) unit but the gates G1 remain blocked since no signals 01 exist. However a signal 02 does exist so that, via OR gate 62, AND gate G3 becomes conductive on pulse #e, the gates G5 remaining blocked since decoder ADEC2 is inactive. At the following pulse #p, i.e. during the subsequent read phase, the resulting bit in shift register SRI is shifted to enable gate RG and gate the contents of register DR on to the data bus DB. The second address part of the instruction activates decoder ADEC 2 in the specified (receiving) unit, and via shift register SR2, enables gate WG to connect the register DR to the data bus to receive data during the same subsequent read phase. In the receiving unit the operational part of the instruction is decoded to activate the appropriate one of the lines 02 which, because of the output from ADEC2 and AND G4, activates the appropriate one of the elements E2 via a gate G5 to cause the specified operation to be performed with the received data. In a modification the operational part of an instruction includes two parts with respective decoders corresponding to signals 01 and 02 above, the second part corresponding with the second address part of a second type instruction and being sent over the bus in the read phase following the phase in which the instruction was accessed so that the shift register SR2 to delay the actuation of the receive gate WG is omitted.

Title: Frequency modulated oscillating system
IPC: H03C3/24
Filed: 1946-06-28
Abstract: 614,066. Frequency modulation; valve generating circuits. STANDARD TELEPHONES & CABLES, Ltd. June 28, 1946, No. 19413. Convention date, Sept. 15, 1945. [Classes 40 (v) and 40 (vi)] An oscillator for generating frequencymodulated waves, comprises an amplifier with an output tank circuit, a transmission line of electrical length exceeding one wavelength connecting the output circuit to an input phaseshifting network, and means to apply a signal wave to vary the phase-shift produced by this network. In Fig. 1, the output from an oscillator valve 10 is applied to a tank circuit resonant at mid-frequency, comprising coil 17 and condensers 23 to 26. Condenser 24 is a blocking condenser and condensers 25 and 26 form a potentiometer. Energy is supplied to a load circuit 30. For feedback purposes the output from point 31 is applied to a coaxial transmission line 33, the length of which preferably exceeds five wavelengths. Other types of transmission line, or wave-guide may be used in place of coaxial line 33. The other end of the transmission line is applied to input tank circuit 35, 39, 37, which is connected through a phase-shift network to the input of valve 10. The phase-shift network comprises a condenser 40 and a resistance 45 in series with the resistive impedance to earth provided by the circuit comprising valves 48 and 59, and also condenser 42 and resistance 44. The impedance provided by valves 48 and 59 is controlled by modulating signals applied to the control grid of valve 48 through transformer 54. The modulating signals may be at audio or video frequency. The arrangement is such that in the absence of modulating signals, the impedance at the input end of transmission line 33 is made equal to its characteristic impedance, so that no reflection occurs. When the impedance conditions change owing to the application of modulating signals, valves 48 and 59 effectively act as a variable resistance, introducing a phase change in the feedback circuit so that the oscillator immediately operates at another frequency, whereby the feedback is applied at 180 degrees and the electrical length of line 33 is such as to provide non-resonant operation. The arrangement may be regarded as a means for varying the electric length of the feedback line at modulating frequency. Short lengths of transmission lines may be provided in place of the capacity and inductance elements of the output tuned circuits as shown in Fig. 2, and short transmission lines may also be provided at the input tuned circuit stage (Fig. 3, not shown). Other modifications include the use of quarter-wave sleeves to assist in balancing the ends of transmission line 33, the use of a low-frequency alternating power supply, or of inductors in place of condensers 40 and 42. Valve 48 may also be used without valve 59.

Title: Improvements in automatic acceleration control systems for electric traction motors
IPC: B60L15/12
Filed: 1945-07-30
Abstract: 601,175. Control of D.C. motors; electromagnetic switches. RAMSDEN, H. K., and METROPOLITAN-VICKERS ELECTRICAL CO., Ltd.. July 30, 1945, No. 19479. [Classes 38 (iii) and 38 (v)] A control system for a traction motor is provided with a number of sequential accelerating contactors such as Ma-Mc, Fig. 1, operated by a controller and respectively in series with one of operating coils A-C so that energization of coil A opens contacts A1, closes a holding circuit for. itself over contacts A2, and also prepares an operating circuit for coil B by closing contacts A3, a similar operation being effected on contacts B1-B3 and C1-C3 by the operation of contactors Mb and Mc, the preparing circuits being also controlled through the contacts 4 of a currentlimiting relay which is opened by a shunt coil II associated with a holding coil I in the motor circuit, whereby contact 4 is held open and prevents energization of the succeeding contactor until the motor current has fallen to a predetermined value. Energization of coil A also closes line contacts A4, coil B closes contacts B4 to short circuit a resistance R1, and coil C closes contacts C4 to short circuit a resistance R2. Energization of coil C also prepares a circuit for a coil D and a " set-up " coil III, the energization of D acting to close a contact D1 in a diverter circuit R3 for the series field of the motor. The " set-up " coil III is associated with the magnetic circuit of the current limiting relay, and acts in opposition to the winding I, thereby causing the relay armature to fall at a higher value of motor current and compensating for the increased armature current in the high speed position, due to field weakening. The system provides protection should the master controller be moved from the " off " position through several notches rapidly, since the contactors do not operate immediately. Relay construction. The relay contacts 4, Fig. 3, at the ends of terminal members 4a mounted on an insulating bar 5a co-operate with the end contacts of a slidable conducting bridge 4b which is provided with two apertures to receive the parallel limbs of a supporting guide 4d carried by an arm 4e, Fig. 2. A plunger 4c projects from the bridge 4b through a hole in the guide 4d and co-operates with the upper end of an armature 6, the contacts 4b being normally closed on contacts 4 by the pressure of a spring 5b when the armature is inoperative. The actuating coil II of the relay is mounted on a core 11 which carries a shortcircuiting turn 13 beneath the coil for the purpose of providing a delay in the armature release when the circuit including the coil II is broken and allowing time for the holding coil I, mounted on a parallel core 9, to become effective. The coil III which acts in opposition to coil I is mounted on the outer end of the core 9. An adjustable end 10 may be provided to vary the air-gap between the armature and the core 9, and a non-magnetic shim 12 may be interposed between core 11 and the armature.

Title: Preparation of diorganohalophosphines
IPC: C07F9/52
Filed: 1964-05-13
Abstract: Diorganohalophosphines of the formula R2PX wherein R is a hydrocarbon radical and X is a halogen atom, are prepared by reacting an aminodiorganophosphine of the formula R12NPR2, wherein each R1 represents a hydrocarbon radical or the two R1 radicals together with the N atom form a saturated heterocyclic ring with a phosphorus trihalide of the formula PX3.  R and R1 are preferably alkyl having not more than 8 carbon atoms and X is preferably Cl. The compound R12NPR2 may be obtained by reacting an aminodihalophosphine of the formula R12NPX2 with an organic aluminiu compound of the formula RnAlX3- n wherein n is an integer from 1 to 3, an aluminium halide being obtained as by-product. Since an aminodihalophosphine of the formula R12NPX2 is formed as by-product in the process of the invention it may be reused to form the compound R12NPR2 in the above process. The aminodihalophosphines may be prepared by a one-stage aminolysis of a phosphorus trihalide.  Alternatively, a mixture of a triaminophosphine and a phosphorus trihalide may be used in place of the aminodihalophosphine. Moisture and oxygen are preferexcluded from the reaction mixture by gases such as N2 or CO2.  An example is given for the preparation of (C2H5)2PCl.  The organic aluminium compounds of the formula RnAlX3- n may be prepared by way of Grignard compounds or by direct synthesis from olefines, hydrogen and aluminium in the presence of a catalytic amount of preformed trialkylaluminium. Trimethyl and triethylaluminium can also be obtained by dehalogenation of the corresponding dialkyl halides by means of Na, or by distillation of the complex compounds formed from dimethyl- or diethyl-aluminium chloride and NaCl or from dimethyl- or diethyl-aluminium fluoride and NaF.  Methyl-aluminium dichloride is also obtained from dimethyl ether, AlCl3 and Al.
