Filed: 1960-10-31
Abstract: <PICT:0972812/C1/1> An optical element of magnesium fluoride is made from pure microcrystalline magnesium fluoride powder by pressure between 10,000 and 25,000 pounds per square inch while maintaining <PICT:0972812/C1/2> the temperature thereof within the range 1150 DEG to 1420 DEG  F. for a sufficient period to ensure it becomes homogeneous.  As shown in Fig. 3, the magnesium fluoride powder 10 is placed in a mould comprising a ring mould 12, block 13, insulator 15 and block 16 secured in a base 16 and is pressed by a plunger 17 secured to a head 8 which is attached to the piston of an hydraulic press (not shown).  The plunger 17 passes through a ring 18 secured to the head 8 by a metal bellows 20 forming a vacuum seal. A vacuum chamber 30 is formed around the mould by base 16, top plate 19 and cylinder 29 and connected by conduit 24 to a vacuum system. The mould 12 is closely surrounded by a cylinder 21 and heating coils 11 and the cylinder 29 is surrounded by cooling coils 25.  The temperatures adjacent the moulding positions are measured by thermocouples 28 and 31.  The materials used for the moulding parts, i.e. the mould 12, plunger 17 and block 13 may be of molybdenum, tungsten, graphite, high density alumina or super alloys.  A gas, such as nitrogen or helium may be used in the chamber 30 in place of the vacuum.  The operation is preferably as follows:  cold pressing at 5000 lb. per square inch for a few minutes to compact the powder, removal of any loose powder and then heating the coils 11, while producing a vacuum in chamber 30 and the cooling coils 25 are operated, to a temperature of 1380 DEG  F. and then applying pressure of 15,000 to 25,000 lb. per-square inch for from 40 to 60 minutes with the temperature held between 1380-1420 DEG  F. To form a block 10 of magnesium fluoride hermetically sealed into a ring 40 of steel, the ring mould 12 is recessed to take the ring 40, the hot pressing causing the powder to seal to the steel. High-frequency heating may replace the heating coils shown in Fig. 3.  Specification 913,175 is referred to.

Title: Voltage-controlled pulse generator
IPC: H03K3/30
Filed: 1973-08-07
Abstract: 1395853 Transistor pulse generators GAMMA MUVEK 7 Aug 1973 37419/73 Heading H3T In a voltage controlled free-running pulse generator for generating a pulse train output when an input voltage 1 is applied comprising two amplification stages built up from two opposite conductivity type transistors 3, 4, a voltage divider 5 constituting the load of one of the amplification stages and an adding circuit 6 connected to the control input electrode of this amplification stage, the output electrode of this stage 3 is connected to the control electrode of the other stage 4 via a series circuit including a transformer secondary winding 7, a constant voltage source, such as a Zener diode 10, a diode 9 and a capacitor 8, the primary of the transformer 7 is connected in the circuit of the output electrode of the other amplification stage 4 and a direct current voltage generated in proportion to the pulsed output signal of the generator is added to the input voltage in the adding circuit 6. On increasing the input voltage 1 current flows via a resistor 11 to change the state of a transistor 4 from a blocked to an operating condition. On further increasing the input voltage the voltage at the voltage divider 5 reaches the value of the voltage source 10 formed by a Zener diode. This causes the diode 9 to conduct, the base current of the transistor 4 to increase and a voltage to be generated at the secondary winding of the transformer 7 which further increases the base current. After some delay determined by the inductivity of the transformer 7 the collector current of the transistor 4 reaches its base-current-determined value. When the collector current has reached this value the collector voltage of the transistor 4 increases, the collector current falls in an avalanche-like manner controled by the transformer 7. The base current has charged the capacitor 8 to a voltage that exceeds the voltage at the voltage divider output, so that the voltage of the capacitor 8 keeps the transistor 4 blocked until it discharges across the resistors 11 and 12 to enable the base current to flow again. The output of the generator is rectified at 13 and passed via an integrating circuit 14 to the adding circuit 6 so as to be superimposed on the current generated by the input source 1. If the voltage of the input source 1 fall, switching offresults at a lower value than the switching on value and the circuit therefore displays hysteresis. In a modification (Fig. 2, not shown), the load resistance RL is not applied to a separate winding of the transformer 7 but to the collector of the transistor 4. In a further modification the current generating the hysteresis effect is obtained by feeding the rectifier 13 from a separate winding of the transformer.

Title: Improvements in and relating to television receivers

Filed: 1964-09-18
Abstract: 1,042,567. Television receivers. BLAUPUNKT-WERKE G.m.b.H. Sept. 18, 1964 [Sept. 20, 1963], No. 38173/64. Heading H4F. In a television, receiver having a transistorized intermediate frequency amplifier, a video rectifier and a video amplifier with contrast control, wherein the difference between the black levels of the signal output voltage of the video amplifier during regulation of the contrast is reduced, the preliminary stage, which is transistorized, of the video amplifier contains an adjustable voltage divider 12 for the contrast control, and a transistor 5 whose characteristics and operating point are such that the synchronizing pulses cause the transistor to bottom, thus limiting the amplitude of the pulses. The video rectifier comprises a video intermediate frequency oscillating circuit 1, a diode 2, a charging capacitor 3 and a load resistor 4 and supplies the base of the NPN transistor 5 of the preliminary stage of the video amplifier with a video signal containing negative synchronizing pulses and with a positive bias from resistors 7 and 8. The tap of voltage divider 12 (contrast control) is connected to the input of the end stage of the video amplifier comprising pentode 13, the output terminal 14 being connected to a cathode-ray tube. Terminal 15 connected with the collector of transistor 5 is connected via voltage divider 10, 11 to the input of a single stage amplitude filter of the television receiver. At terminal 15 there is a voltage 18, Fig. 2, not shown, containing positive synchronizing pulses, the amplitude of which is dependent on the setting of the tap of voltage divider 12 and on the ratio between the total resistance of divider 10, 11 and the resistance of divider 12. The circuit is so adjusted that the transistor 5 is bottomed by a signal voltage having an amplitude of between <SP>1</SP>/ 3  and <SP>2</SP>/ 3  the amplitude of the synchronizing pulses, thus the transistor is cut off during the synchronizing pulses so that a maximum voltage determined by the no-load voltage of divider 10, 11 occurs at terminal 15. The cutting of the peaks of the synchronizing pulses reduce any interference impulses to the level of the synchronizing pulses and reduces the differences between the black level voltages when the contrast is changed so that there results a sufficient black level maintenance. The potential of the emitter of transistor 5 corresponding to a black level video signal may be reduced to zero by means of a resistor 25 connected to a negative potential. To ensure that any interference pulses are smaller than the synchronizing pulses a D.C. blocking capacitor may be connected in lead 17. In a colour television receiver the top of voltage divider 12 is connected to the base of a PNP transistor, Fig. 4 (not shown), the collector of which is earthed and the emitter connected to a delay line 38, at the other end of which a delayed picture voltage, serving as a luminance signal, is obtained.
