[Class 38 (v).] Contacts; sparking-preventing devices.-The movable contact-member 1 is pivoted at 2 and carries at one end a pair of brass posts 10, 11 which are removably secured by nuts 14 and have contact surfaces 12, 13 of tungsten. These surfaces co-operate with similar surfaces on similar posts 15, 16, which are mounted on leaf springs 19, 20 which are mounted so as to be electrically connected. Stops 25, 26 are provided for the posts 15, 16, the arrangement being that as the arm 1 rotates about its pivot 2 to separate the contacts 10, 11 from the contacts 15, 16, the latter follow up until arrested in turn by their stops, circuit being broken last of all at contacts 11, 16, which thus take the sparks. When the latter contacts are sufficiently worn away they can be replaced. Electric-motor actuation.-The arm 1 is held by a spring 4 so that its remote end bears on a cam 3 driven by a motor 7 in circuit with a generator 8, which supplies a load 24 in series with the contacts of the switch.

Title: Improvements in or relating to transistor d.c. amplifiers
Inventor: COOKE-YARBOROUGH EDMUND HARRY
IPC: H03F1/30
Filed: 1959-11-03
Abstract: 891,424. Transistor amplifying circuits. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Oct. 28, 1960 [Nov. 3, 1959], No. 37337/59. Class 40(6). A low drift D.C. current amplifying stage comprises a junction transistor, an input current connection to the base, a source of voltage pulses, and a capacitor connected between the source and the base whereby the capacitor is charged during each pulse through the emitter/base junction and is discharged between pulses by the input current flowing through the input current connection, the charging and discharging time-constants being long compared with the pulse duration and the period between pulses respectively. It is shown that a low drift amplifier should be designed to draw only a small mean collector current Ic and by using the above arrangement the emitter efficiency is maintained at very low mean emitter currents by pulsing the emitter so that it  injects carriers for only a small proportion of the total time. Negative pulses of constant amplitude, duration and repetition frequency are fed from a low impedance source via terminal P1 and a capacitor C to the base of the transistor and if the pulses are long compared with the mean transit time of the minority carriers from emitter to collector then between pulses the emitter/base junction is reverse biased and no base current flows other than the reverse currents of emitter and collector which are negligible. The charging and discharging timeconstants of the capacitor C are made long compared with the pulse duration and the period between pulses respectively, so that for a given input current the voltage across C and hence the charge and discharge currents, remain substantially constant during these periods. Thus if a particular peak emitter current is chosen as being the least which will provide the desired current gain, then pulsed operation allows all the mean currents to be scaled down by a factor K, where K is the duty cycle of the pulse, below their values for normal D.C. operation while the D.C. gain remains unchanged. The case of when the pulses are shortened is also considered as well as when the pulse duration is comparable with. the mean carrier transit time. The transistor may also be connected in the common collector configuration.

Title: Process for producing drawn filaments of polycaproamide
IPC: D02J1/22
Filed: 1971-08-10
Abstract: 1310776 Polycaproamide filaments ALLIED CHEMICAL CORP 10 Aug 1971 [10 Aug 1970] 37485/71 Heading B5B A process for producing drawn filaments of polycaproamide comprises extruding molten caproamide to form filaments, solidifying the filaments by quenching them, applying a spin finish to the filaments, feeding the filaments by a heated feed roll to a first draw roll so as to draw the filaments, cooling the filaments between the feed roll and the first draw roll by blowing air under pressure at them, further drawing the filaments between said first draw roll and second draw roll and winding up the filaments. The temperature of the heated feed roll may be from 80 to 120 C., and the filament temperatures immediately before and after the cooling by blowing air under pressure between the feed roll and the first draw roll may be respectively 80 to 95 C. and 50 to 70 C. The first draw roll may have an associated separator roll or may be cooled by blowing ambient air across it. The draw ratio between the feed roll and the first draw roll may be from 1À01 to 2À17, and the total draw ratio may be from 2 to 5, especially from 3À5 to 4À6. In apparatus as shown, yarn 1 leaves a quenching chimney 2 below a spinnerette. Yarn 1 then passes over spin finish applicator roll 3 and on to feed roll 4, optionally equipped with step roll (not shown) and with separator roll 41. Air cooling jet 5, fed by ambient temperature air, cools the yarn as it is drawn between feed roll 4 and first draw roll 6. Separator 7 for draw roll 6 can be in the normal position as shown, or in the lower separator roll position as shown by 7a. The second draw step takes place between the first draw roll 6 and second draw roll 8, having its associated separator roll 81. Yarn 1 then passes to winder 9. Yarn so made shows an improved resistance to ozone-fading, having a #E value of less than 3À3, ultimate tensile strength of 4À0 to 7À5 g.p.d. and ultimate elongation of 25 to 60%. Preferred #E values are from 2À5 to 3À2. The invention is particularly useful for the production of yarn having filaments of Y-shaped crosssection. A typical modification ratio for such filaments is 3À4.

Title: Automatic starting device for putting steam turbines into operation
IPC: F01D19/00
Filed: 1946-12-20
Abstract: 619,726. Steam turbines. ANSALDO SOC. ANON. Dec. 20, 1946, No. 37574. Convention date, April 28, 1941. [Class 110 (iii)] An arrangement for starting a steam turbine, in which the regulating valves are normally operated by pressure oil under a pressure controlled by the speed-governor, comprises a series of valves 30-33 operated by cams 24-27 on a manually-operated shaft 20. The speedgovernor 3, receives oil from a regulating pump 2 which is fed by a main pump 1. Pressure oil from the governor passes through a non-return valve 4 to the operating cylinders of the turbine valves 5, 6, 7. When the turbine is at rest, the control oil pipe between the governor 3 and valve 4 is connected to waste through the valve 31. In starting the shaft 20 is turned in steps. At the first, valves 30 and 32 are opened. Valve 30 admits steam to an auxiliary oil pump 11, which thereupon delivers oil through a restricted orifice 13 to the bearings, and the valve 32 connects the delivery of that pump to the control oil pipe beyond the valve 4. The valve 33 is shut, closing the leak 10 from the control oil line. Further rotation of the shaft increases the supply of steam to the pump 11 until the turbine reaches a speed at which the governor 3 can take control. Valves 30, 31, 32 are then shut, stopping the pump 11 and putting the governor 3 in control. The valve 33 is opened to render the leak 10 effective. In the final position of the shaft 20, a gap in a cam 23 is in line with the piston rod of the associated cylinder 28. If the control oil pressure fails, as, for example, when the emergency governor 9 goes into action, the pressure in the cylinder 28 fails and the piston is pressed upwards and, through a lever 29, opens the valve 30 to restart the pump 11. The speed-governor may be a mechanical one operating through servomotors. In another arrangement, the emergency governor, when operating, cuts off the oil supply from the governor 3 and diverts it to a device on the shaft 20 which turns the latter to the starting position.

The integration in the channels is carried out by filters 9, 10 which in addition reject the best frequency (F 0 -F 1 ) and pass the Doppler shift #F. The filter outputs are detected at 11 and 12 to give outputs which vary with the position of the echo within the range bin as shown in Figs. 4 and 5 respectively. The high 'noise' levels U MAX (2<SP>n-2</SP> - 1/2<SP>n</SP>-1) and U MAX (2<SP>n</SP> <SP>-2</SP>/2<SP>n</SP> - 1) are eliminated and the peaks emphasized by a subtraction process at 13 which yields the final response' of Fig. 6. The multiplying process of 4 and the integrating processes of 9, 10 produce the equivalent of a correlation between transmitted and received signals.
