Filed: 1973-10-05
Abstract: 1435795 Charging coke ovens; drying coal BRITISH STEEL CORP (CHEMICALS) Ltd 4 Oct 1974 [5 Oct 1973] 46700/73 Headings F4B and F4G A coke oven plant has a bunker for wet coal and coal preheater, means being provided to convey wet coal either directly to the coke ovens or to the coal preheater. In the form of Fig. 1 the charging car 18 has rails 20, Fig. 2, to support a carriage 21 with a travelling conveyer belt 22 arranged to be fed with wet coal by charging shoots 23. The conveyer carries the wet coal across the top of the charging car and passes it to another conveyer 24 which runs in a closed duct to the coal preheater 19. From the preheater coal is conveyed by conveyer belt 26 in duet 27 to the top of the preheated coal bunker 17. The ducts are interconnected by a duct 28 so that an inert gas can be circulated over the preheated coal in duct 27, down duct 18 and through duct 28 to dry and heat the coal on its way to the preheater. In a modification the conveyer runs on rails on the fixed structure. In another form (Fig. 4, not shown) two charging cars are used instead of the conveyer 22, the cars being movable sideways in one direction to convey preheated coal to the ovens and in the other to convey wet coal to a conveyer taking it to the preheater.

Abstract: 1517110 Radio receiving systems SIEMENS AG 29 Nov 1976 [28 Nov 1975] 49642/76 Heading H3Q In a frequency spectrum analysis equipment a receiver 1 has an adjustable bandwidth (fu-fo, Fig. 2 not shown) which can be switched over in steps from an initially large bandwidth (B0) to successively smaller bandwidths (B1, B2) the rate of change of the frequency settings is initially rapid, until a received signal (Ux) is detected having an amplitude of a certain amplitude, then a comparator 4 causes a control device such as a computer 5 to set the bandwidth at a narrower value (B1) and also retraces a given frequency range at a slower rate of change of the receiver tuning. The subsequent received signal, if any, causes a further reduction of band width (B2) and rate of change of tuning to occur and a recording or display device 8 is automatically connected such as by a gate 7 to the output of the receiver. The control device 5 then automatically reverts to the initial bandwidth and rate of change of tuning control when the receiver output falls below a given value. The output of the receiver provides amplitude information of the received signals and is fed to a chart recorder or c.r.t. beam defection circuit 8. The receiver 1 is tuned over the range fu-fo by a frequency synthesizer 3 under control of the computer 5. In a modification (Figs. 3 and 4, not shown) the synthesizer 3 is replaced by an oscillator (14) controlled by a function generator (13) and digital operating comparator 4 is replaced by an analogue operating comparator (20).

Title: Transistor reverse biased second breakdown testing apparatus

Abstract: 1,115,178. Transistor pulse circuits. RADIO CORPORATION OF AMERICA .24 Nov., 1965 [28 Dec., 1964], No. 50015/65. Heading H3T. [Also in Divisions G1 and G3] In a circuit for testing the reverse biased second breakdown of a transistor 12 current is supplied from a variable current source 10 through an inductance 14 and Zener diode 16 to the collector of transistor 12. The variable current source 10 operates to keep constant the current flowing into the inductance 14, this constant current being determined by the position of the sliding arm on a potentiometer 82 (see Division G3). Transistor 12 is periodically pulsed into conduction (saturation) by pulses from a pulse generator 20. The pulses have steep trailing edges and the transistor is normally reverse biased by E - so that at the end of each pulse the inductor 14 produces a high induced test voltage at the collector. The test voltage is increased by increasing the current from source 10 or by increasing the inductance of inductor 14 until, for a predetermined reverse bias, second breakdown occurs, at which time a radio frequency noise occurs between the base and emitter of transistor 12. This is detected by oscillation detector 32 which over a mono-stable multivibrator 38 operates a clamp circuit 40. Clamp circuit 40 comprises a short-circuiting device including a transistor Q8 which conducts to short-circuit the collectoremitter of transistor 12 after reverse biased second breakdown. If the breakdown voltage of transistor 12 is greater than that of transistor Q8, then by manipulation of ganged switches 122, 124, a silicon controlled rectifier Q7 may be substituted as the short-circuit element for transistor Q12. Zener diode 16 is provided to overcome the resistance of diode 42 and render clamp circuit 40 conductive. When this circuit is conductive a pulse is sent over line 46 to " set " a bi-stable clamp circuit 26 which energizes a second breakdown indicator 28 and applies a voltage over line 129 to block the pulse generator 20. At the same time voltage is applied over line 48 to disable the variable current source 10.
