Title: Improvements in and relating to regulating apparatus for electric circuits
IPC: H02P9/10
Filed: 1927-01-15
Abstract: 264,527. British Thomson-Houston Co., (Assignees of Alexanderson, E. F. W.). Jan. 15, 1926, [Convention date]. Regulation; automatic systems depending on two or more machines.-An alternator, supplying for example, a high voltage transmission line subject to instability, is regulated so as to respond immediately to changes due to load variations whereby stability is increased. The exciting current is controlled by an electric discharge or continuous arc device 6 energized from the supply circuit 4. The phase relationship between the grids 15 and anodes 13 of this device is controlled so as to vary the proportion of each cycle during which current passes by a phase shifter 26, deriving its potential from the supply circuit, and by a bias device in series relation in the grid circuit. The phase shifter is used to set the rotor 24. The bias device derives its potential, from a transformer 33 which is energized according to the phase difference between the terminal volts of the generator 3 and those of an alternator 34 mechanically coupled to the generator. A rectifier 32 passes rectified impulses into a transformer 20 the rate of change of which determines the extent or positive or negative bias temporarily present in the grid circuit. A direct current machine may replace the alternator 34 and rectifier 32 and an alternative phase shifting device described comprises a, condenser and resistor. The Specification as open to inspection under Sect. 91 (3) (a) described an arrangement with a steady positive bias in the grid circuit such arrangement being automatically responsive to voltages in the supply circuit. This included a phaseshifting device comprising a condenser and resistor. This subject-matter does not appear in the Specification as accepted.

Abstract: 918,892. Making heat exchangers. OLIN MATHIESON CHEMICAL CORPORATION. Jan. 12, 1961 [Jan. 29, 1960], No. 1389/61. Class 83 (2). A method of making a heat exchanger 20 from a seamless metal blank which has distended tubular passages 18 therein surrounded by solid web portions 19 comprises cutting the web portions between adjacent passages and separating the cut edges 24 and 25 sufficiently to alter the cross-sectional shape of the passages so as to increase their projection from the face of the blank. The cut edges 24 and 25 are separated by conventional means such as a tapered mandrel which simultaneously re-shapes the ] assages as at 23 so that the major dimension of the cross-section is transverse to the panel. The edges 24 and 25 form flanges 26 and 27 which may be used to mount secondary heatdissipating fins, or which may be folded over against the sides of the passages 23 to reduce their projection into the duct 22. The secondary fins may be strips of metal bent into serpentine form and secured by conventional means such as soldering or brazing. The crests of the folds of the secondary fins may be notched to assist in securing them. A plurality of the completed panels may be assembled face to face with the ducts 22 aligned or in staggered relationship. Alternatively the panels may be assembled face to face with the duets 22 aligned and secondary fins inserted which extend through all the panels. Specification 759,804 is referred to.

Patent GB-413642-A (GB)
Title: Improvements relating to the control of direct current electric motors
IPC: B60L15/04
Filed: 1933-01-16
Abstract: 413,642. Master control of D.C. motors ; interlocked controllers. GRAY, W. T., Darroch, Wainwright Road, Altrincham, Cheshire, and ASSOCIATED ELECTRICAL INDUSTRIES, Ltd., Crown House, Aldwych, London. Jan. 16, 1933, No. 1421. [Class 38 (iii).] In a master control system for two motors or two groups of motors 1, 2, Fig. 1, in which either of the motors or groups of motors may be cut out when desired, a switch associated with the master controller MC is arranged to co-operate with interlock contacts on the motor cut-out switches C1, C2, so that the control circuits for the motor power connections are completed only when the switch associated with the master controller, and the motor cut-out switches are both in positions corresponding to all the motors being in circuit, or in positions corresponding to one of the motors or groups of motors being cut out, and a mechanical interlock is provided between the main control drum of the master controller, and its said associated switch, so that if the switch is in a position in which one of the motors or groups of motors is cut-out, the main control drum cannot be moved beyond the position in which the motors or groups of motors are in series. As shown, the cut-out switches C1, C2 are of the knife type and the switch associated with the master controller is incorporated in the reversing switch forming part of the master controller, which reversing switch, for this purpose, has four positions. The main drum 9, Fig. 5, of the controller is mounted on a shaft 10 which carries a ratchet 13 having a radial hole 15 engaged by the head of a lever 17 pivoted at 16. The associated reversing switch is mounted on a shaft 19 which carries a ratchet 21, against the notches 22, 23, 24, of which the lever 17 is biassed with the reversing switch in the " off " position shown, a roller 18 on the lever 17 is engaged in the notch 22 which maintains the head of the lever 17 in the bore 15, so that the main drum cannot be operated. When the reversing switch is moved to a " motor cut-out " position, either for forward or reverse operation, the roller 18 engages one of the deeper notches 23, which allows the head of the lever 17 to leave the bore 15, and ride on the outside of the ratchet 13, to an extent limited by the stepped portion 14. Thus, the main drum may be operated to its series, but not its parallel positions. If the reversing switch is moved to a " both motors in " position, either for forward or reverse operation, the roller 18 engages one of the still deeper notches 24, which allows the head of the lever 17 to clear the stepped portion 14. Thus, the main drum may be operated to series and parallel positions. The cut-out switches may take the form of a drum, combined with, or independent of the reversing switch, and the cut-out switch or switches may be combined with a power-brake switch. Specification 413,641 is referred to.

Title: Improvements relating to electricity meters
IPC: G01R11/36
Filed: 1931-01-17
Abstract: 363,178. Eddy current brakes. SIEMENS BROS. & CO., Ltd., Caxton House, Tothill Street, and RIBER, C. R., 24, Dorville Road, Lee, both in London. Jan. 17, 1931, No. 1615. Addition to 310,390, [Class 37, Electricity, Measuring &c.] [Class 103 (i).] In the induction motor meter described in the parent Specification, the swivelling motion for adjusting the brake magnet is effected by means of a cam. The brake magnet 25 is secured to the part 6 of the frame by means of a screw 16 engaging a threaded washer 17 which has turned-over ears to prevent rotation when the screw is turned. Between the magnet 25 and the part 6 of the frame is a washer 18 having three threaded d holes to take levelling- screws 23 and a central hole through which the screw 16 passes. The heads of the screws 23 pass freely into elongated holes in the part 6. The washer 18 has three pips or protuberances 19, giving three-point contact with the part 6. An arm 20 is integral with the washer 18 and carries at its end a slotted head 21 provided with an eccentrically-mounted stem which passes through the arm and is burred over at its end. The head 21 carries a stop 22 which encounters ears 7 on the part 6 so as to limit the rotation of the head 21 to about 190‹. Between the head of the screw 16 and the part 6 is a bowed spring washer 24 having a claw which registers with one of the screws 23, so that rotation of the head 21 causes the washer 18, magnet 25, and spring washer 24 to rotate together through a small angle. Friction between the head of the screw 16 and the spring washer 24 causes the screw 16 to turn with the washers 18, 24, thereby preventing tightening or slackening of the screw. The cam member 21 may be mounted about the same axis as the screw 16 and have a projection engaging an aperture in the washer 18, or the member 21 may be eccentrically mounted on the part 6 of the frame and co-operate with a slot in the washer 18.

Abstract: 1365281 Semi-conductor devices PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 7 July 1971 [10 July 1970] 01867/74 Divided out of 1363515 Heading H1K One or more highly doped buried zones 62, each of which forms a P-N junction with an underlying semi-conductor substrate 68, interrupt inversion channels which might otherwise interconnect islands such as 69 defined in a Si epitaxial layer 61 by a pattern of silicon oxide 65 which penetrates through the layer 61 to the buried zone(s) 62 and is formed by selective oxidation thereof. Each zone 62 extends across the entire bottom of at least one of the islands 69, and in a modification of the illustrated structure a single common zone 62 underlies all the islands and the intervening oxide pattern 65. The epitaxial layer 61 is preferably of the same conductivity type as the substrate 68. The zones 62 are preferably provided by predoping the substrate 68 before deposition of the layer 61. The pattern 65 may be formed by steam oxidation through a silicon nitride or an oxidenitride mask. Recesses may be etched half-way through the layer 61 prior to oxidation so that the pattern 65 finishes flush with the upper surface of layer 61, or the same result may be achieved by oxidizing initially only partly through the layer 61, etching the oxide so formed and reoxidizing to complete the pattern 65. Alternatively the pattern 65 may be allowed to project above the layer 61, or the excess oxide may be removed after oxidation. Transistors, diodes, resistors, capacitors and PNPN photo-detectors may be formed in the isolated islands 69.
