Patent GB-131875-A (GB)
IPC: H01H51/12
Abstract: 131,875. Soc. Anon. des Etablissements L. BlÚriot. Aug. 28, 1918, [Convention date]. Electro-magnetic interrupters; switches, quickaction; contacts.-In an electro-magnetic switch, the armature b is carried on one end of a bellcrank lever, the other end of which lies between two adjustable projections on a contact-carrying rocker e. The rocker has on its lower end a knife edge e<2> adapted to ride over a knife edge on a spring-pressed lever j. A spring blade g<1> moving between adjustable stops l<1>, l<2> carries a contact g, which bears continuously on the contact f on the rocker when the latter is between its mid-position and one of its inclined positions. These contacts when closed short-circuit a resistance i, and the magnet is fully energized; the armature is then attracted moving the rocker rounter-rlockwise beyond its mid position, the lever ensuring a snap action. With the rocker in its other extreme position, the contacts f, g separate, and the spring c brings the bell-crank, rocker, &c., to the position shown, thus obtaining continuous oscillation. In a modification, the return spring c is dispensed with and two alternately energized electro-magnets are used acting on armatures on opposite ends of a bar, an arm at right-angles to the bar lying between the rocker e. Two sets of contacts such as f, g are used controlling the energizing of the two electro-magnets. The resistance i may be of such strength as only to compensate for the difference in reluctance of the magnet circuit, which obtains between the armature in its attracted and released positions.

Patent GB-131428-A (GB)
Title: Improvements in or relating to Steam Turbines.
IPC: F01K13/02
Filed: 1918-08-16
Abstract: 131,428. Guy, H. L., and British Westinghouse Electric & Manufacturing Co. Aug. 16, 1918. Motor power plant; cooling parts. - In turbines comprising sections adapted at times to rotate idly, steam for cooling is supplied to these idly rotating sections by a special pipe or passage, as distinguished from a channel in a packing-gland through which leakage steam can be supplied from one section to another. The cooling steam may be taken from an operative turbine section in which it has been cooled as a result of doing work. Fig. 1 shows highpressure ahead and reverse sections 4, 5 on one shaft and low-pressure ahead and reverse sections 6, 7 on another shaft. A pipe 10 having a handcontrolled or non-return valve 11 permits steam to pass from the operative section 4 to the idle reverse sections 5, 7. When the reverse sections are operative, a valved pipe 13 leads steam to an intermediate stage of the idle ahead section 4. Another valved pipe 14 may supply steam to the idle ahead section 6. In some cases, a valveless pipe 17 may be arranged to supply steam for cooling from the ahead to the reverse sections or vice versa, depending on which sections are operative, the ends of the pipe 17 being so positioned that a greater quantity of steam is passed from the reverse sections to the idle ahead section when the turbine is going astern than when the opposite conditions prevail, assuming that the disk friction and windage of the ahead section is greater than that of the reverse section. The pipe 10 may be dispensed with by designing the gland 21 to provide sufficient leakage steam to cool the smaller reverse sections when running idle, additional steam for cooling the larger ahead sections when running idle being supplied by a pipe such as 13. Applications of the invention to a turbine comprising cruising and full power sections and to a combination of a back-pressure turbine and a high-pressure turbine are described.

Title: Integrated circuits
IPC: H01L27/04
Filed: 1970-03-20
Abstract: 1311966 Semi-conductor devices PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 20 March 1970 [24 March 1969] 13485/70 Heading H1K [Also in Division H3] A triggering circuit comprises a capacitor connected between a pulse input and the output and a resistor connected between a level input and the output is formed as an integrated circuit in such a manner that the plate of the capacitor connected to the output is formed as a region of a semi-conductor body surrounded by two isolating PN junctions. In operation the region between the junction is connected to a bias supply so that both junctions are reverse biased. This ensures that the stray capacitance contributed by the isolating junctions varies in such a sense that it is low when the level voltage is low and high when the voltage is high, which enhances the operation of the circuit rather than degrading it as in a circuit with only one isolating junction in which the capacitance varies in the opposite sense to the level voltage. As shown, Fig. 5, the capacitor comprises a P-type region 8 separated from a metal layer 12 by a thin portion 16 of the SiO 2  layer 2, and is surrounded by two PN junctions 9, 6. The resistor comprises P-type region R connected to capacitor plate 8 by conductive track 10 which forms the output of the circuit. The lower face of the wafer is provided with an earthed electrode 4 and the N-type region 5 surrounding the capacitor plate is connected to the highest supply voltage Vcc. The device may be produced by depositing an N-type epitaxial layer on a P-type Si substrate 3, and forming P-type isolating walls 17 and islands 8, R by diffusion. Alternatively the regions may all be formed by diffusion. The capacitor may comprise a reverse biased PN junction instead of the MOS structure shown and the resistor may comprise a buried resistor or a resistive layer formed on the insulating layer.

Title: Improvements in and relating to apparatus for indicating the position or course of a navigable vehicle
IPC: G09B9/26
Filed: 1946-05-07
Abstract: 611,770. Electric follow-up systems. YOUNG, F. B., CHAMPNEY, L., BURNSIDE, W., PLATT, J. M., SHORTEN, F. A., and LAURENCE, SCOTT, & ELECTROMOTORS, Ltd. May 7, 1946, No. 13827. [Class 40 (i)] [Also in Groups XX and XL (c)] In a course-recording apparatus in which a plan position picture of a navigable vehicle's surroundings obtained by radar or other echolocating apparatus is presented for view against a plotting surface, the speed of the driving motor is varied in accordance with impulses from the vehicle's log by an escapement speed control working through a variable friction gear. Resolver 10, Fig. 3, fed by compass repeater motor 16 and driven, in accordance with impulses from the ship's log through escapement 18 and gearing 19, by the motor 17, applies to the course-recording apparatus (see Group XX) the two rectangular components of the vehicle's speed. The variable friction gear, Fig. 8, comprises two conical rollers 71, 72 coupled by an idler disc 73. Roller 71 is driven by shaft 17a from the motor 17 and roller 72 drives the escapement disc 90, Fig. 12, by the shaft 74. The driving ratio may be adjusted by turning a screw 76 through gears 76a, 77a, which engage when the remote control shaft 77 is moved longitudinally, the screw having a carriage 75 mounted thereon in which the idler disc 73 is journalled. Means are provided for using impulses from a clock to give an estimated speed in the event of failure of the log. The plotting scale in use, i.e. miles covered by the ship for each inch of movement of the plotting surface, is shown on scale bar 78 moving with the carriage 75. Rotation of the knob 83 which changes the multiplying gearwheels of the drive also brings into use the scale appropriate to the main gearing. As shown in Fig. 12, the escapement disc 90 carried on a screw-thread 92 of the shaft 74 from the variable gears 71, 72, has two rings of circumferentially spaced studs 91 and rotation of the shaft tends to retract the disc 90 along the thread 92. This tendency is countered by rotation of the disc in the opposite direction by a coiled spring 93 to the extent permitted by periodical movement of an armature 94 out of the path of studs 91 under the influence of an electromagnet 95 receiving impulses from the log or a clock. An adjustable cap 96 on a boss on disc 90 bears against the longest blade 97 of a group of blades carrying electrical contacts c<SP>1</SP>, c<SP>2</SP>, c<SP>3</SP>, c'. Forward movement of disc 90 tends to open the contacts c<SP>1</SP>, c<SP>2</SP> and to close the others. As shown in Fig. 13, these contacts control the shunting and applied voltage of the driving motor.

Abstract: 1,220,424. Melt spinning synthetic polymers. TORAY INDUSTRIES Inc. 17 March, 1969 [21 March, 1968; 27 March, 1968; 13 May, 1968], No. 13995/69. Heading B5B. Synthetic organic thermoplastic polymers are melt spun by extruding the molten polymer downwardly through a spinneret having a number of extrusion orifices, drawing the extruded filaments downwardly through a stationary column of air 300 to 500 mm. long immediately below the spinneret to subject the filaments to draw-down while they are still molten, and subsequently drawing the filaments downwardly through a zone in which they are in contact with air introduced into the path of the filaments by suction flow generated by a downward air flow accompanying the downward movement of the filaments. In the embodiment shown in Fig. 6, an atmospheric air shut-off chimney 12 having a length of 300 to 500 mm. is disposed surrounding and immediately beneath a spinneret 11 and has connected to it a first flow control chimney 17 provided with numerous holes 15. The first flow control chimney is in turn continued by a second flow control chimney 18 provided with numerous holes 19 and with funnel-shaped flow adjusting members 20. The filaments 16 extruded through the spinneret 11 are cooled by air currents a sucked into the chimney by the air current b travelling downwards with the filaments. As the filaments are drawn through the second flow control chimney 18, the air current b is heated by the filaments and a rising air current c is formed by convection, deflected by the members 20 and discharged through the holes 19 as shown at d. The air currents above each member 20 are not disturbed by the rising air currents c formed below each member 20 whereby the filaments are uniformly cooled without being caused to vibrate.
