Title: Improvements in or relating to Television Cameras
Inventor: MATCHELL RAYMOND
IPC: H04N5/205
Filed: 1968-02-26
Abstract: 1,195,811. Television. MARCONI CO. Ltd. 18 Oct., 1968 [26 Feb., 1968], No. 9209/68. Heading H4F. In an apparatus to provide correction for the non-linear characteristic of television camera tubes, the bandwidth of the output video signal is varied for different amplitude levels of the video signal, said apparatus employing a level detecting means used in conjunction with a delay line 1. The delay line is terminated such that it is reflecting at one end (the left-hand end in Fig. 1) and non-reflecting at the other. This latter is achieved by a resistor 2 of value equal to the surge impedance of the delay line. Diodes 6 and 7 in conjunction with resistors 5 and 8 operate as an amplitude level detector in such a way that signals below a certain amplitude cause an equal voltage to appear at the bases of identical transistors 3 and 4 and signals above this amplitude cause the voltage at the base of transistor 4 to be zero, all the input voltage being applied at the base of transistor 3. The output voltage across resistor 2 contains a component due to the amplification of each of the transistors, that from transistor 3 being delayed by T, the delay time of line 1, over that from transistor 4 and a further component, due to transistor 4, which has travelled along the line and been reflected back to resistor 2 thus having a delay of 2T over that from transistor 4. The output voltage is represented vectorially in Fig. 2, where 6 represents the delay time T, G is the gain of the transistors, a and b are the fractions of the input voltage V in  at the bases of transistors 3 and 4 respectively. Hence low input voltages (as previously defined) will cause an output voltage V o  of the form: V o  = G V in  R 0  (a + b cos #t), where R 0  is resistor 2 and a and b are both equal to ¢. Hence the output voltage varies in accordance with the input frequency # in the form of a sine wave. At high input voltages, when the voltage at the base of transistor 4 is zero, the output voltage is not frequency dependent and equals G V in  R 0  at all frequencies.

Title: Improvements in and relating to the cracking of oils and the like
IPC: C10G9/42
Filed: 1920-04-01
Abstract: 141,689. Adams, J. H. April 11, 1919, [Convention date]. Hydrocarbons, cracking; separate heater and evaporator apparatus.-Oils are converted into oils of lower boiling-point by subjecting the oil to a cracking-temperature under pressure in a chamber in which a body of oil is maintained, and condensing the resulting vapours under the same pressure. Means are provided for removing carbon from the walls of the cracking-chamber. The oil is subjected to the requisite temperature while flowing through a path of narrow cross-section formed between the externally-heated wall of the cracking-chamber 12 and a core 68. The result. ing vapours rise through a body of oil maintained in the vapour chamber 13, and are led by pipes 43, 44 to a separator 45 and thence by a pipe 58 to a condenser. The core 68 is rotated by a shaft 23, and is formed with a worm 69 which agitates the oil and removes deposits of carbon &c. to a collecting-chamber 30. Perforated baffles 70 on the shaft 23 prevent undue agitation of the oil in the vapour chamber 13 and minimize priming. The oil supply is preheated, and is fed from a pipe 11 by branch pipes 57, 16 under the control of valves 14, 15 so that it may be made to flow either downwards or upwards through the cracking-chamber 12. The unvaporized residue is led by pipes 34, 47 under the control of valves 25, 55 to a chamber 42 whence it flows, together with liquid from the separator 45, to a collector C to be pumped back to the supply tank for further treatmeut. A battery of cracking-chambers may be used.

Abstract: 195,981. Hart Manufacturing Co., (Assignees of Hart, G. H.). Feb. 24, 1921, [Convention date]. Switches, quick-action; handles.-Relates to snapaction switches wherein the actuating member 7, support 2 and contact carrier member, to which the contacts 19 are attached, are all of U-shape, the detent 12 is cylindrical, and the spring 16 is coiled round the pivot 11 of the actuator and of the switch-arm carrier and embraces with its outer ends the cross members of these two parts. In one position of rest, the detent 12 is held at one end, at the other, passes first through a slot in the actuator, then through a slot 14 in the support, and lastly into a recess in a slot in the carrier member. Actuation of the tumbler 28 turns the actuator and tensions the spring 16, but the carrier member is, at first, unable to move, as the bottom of the wall of the recess therein engages the detent below its centre. Near the end of the travel of the actuator, the curved portion 9' of the slot in it engages the detent to move it downwards sufficiently to cause the wall to press on it above its centre, when this pressure forces it lower still, and finally brings it collinear with the concentric slot in the carrier member. which member is then flung over by the tensioned spring till stopped by a shoulder 3 on the support 2 Removal of the finger from the lever 28 allows the actuator to set back slightly when the lower wall 9 of the slot in it pushes the detent into the recess at the other end of slot in the carrier. The lever 28 is pivoted on a projection on the plate 33 and connected to the actuator by a link 29. A slot in a housing formed on the plate 33 serves as a guide for the lever. In the complete Specification as accepted, Fig. 6 shows the contact carrier member 4 and the stop shoulders 5, by the engagement of the detent 12 with which shoulders movement of the carrier 4 is prevented until the spring 16 is sufficiently strained.

Abstract: 278,656. Junkers, H. Oct. 6, 1926, [Convention date]. Air, removing; single-acting suction-valveless pumps; regulating delivery by opening by-pa,sses and suction valves.-In a fuel pump for internalcombustion engines, air is allowed to escape from the pump chamber 3 by opening a valve 18 during the delivery stroke of the plunger 1. The air may escape to atmosphere or into the suction reservoir 15. The valve 18 may serve also as a by-pass valve for interrupting the delivery at a, variable point in the stroke of the plunger. The liquid level in the reservoir 15 is maintained constant by a float 30 controlling an inlet valve 33. In the form shown in Fig. 2, the air escapes through a passage 42 in the plunger 1 when the end 43 of the passage registers with a port 44 in the barrel 2 or with the inlet port 40. In a variation of this form, the plunger acts downwardly, the air escaping up the passage 42. In another form, the air .escapes through a passage in the wall of the pump barrel and a neck on the plunger to a port opening into the reservoir, and is carried away by a - current of fuel maintained through the top of the reservoir by an auxiliary pump.

Abstract: 668,166. Polarographs. PHILIPS ELECTRICAL, Ltd., GENTRY, C. H. R., and NEWSON, D. W. S. May 9, 1950 [April 6, 1948], No. 9665/48. Class 37. In a polarograph having a dropping mercury electrode, a variable voltage is applied across the electrodes by means of a potentiometer and the current through the solution is measured by measuring the voltage drop across a fixed resistor by means of an electronic null point indicator and a second potentiometer. In the polarograph shown in Fig. 1 a vessel 1 contains the solution 2 to be analysed, into which dips the dropping mercury electrode 3 connected to a mercury reservoir 4. A saturated calomel or other reference electrode is also immersed in the solution 2. A potential is applied across the electrodes by means of a variable tapping on a potentiometer R1 connected across a battery 5. The diffusion current produced in the cell 1 flows through a fixed resistance R2, the circuit being completed through low resistances R, R3. The potential drop across R2 due to the diffusion current is balanced by adjusting the tapping on R3, the balance being indicated by zero reading on an electronic null point indicator 6. The negative terminal of the cell is then at the fixed potential of the junction of the resistances R, R3, so that the setting of the potentiometer R1 indicates the potential across the cell irrespective of the value of the diffusion current, and the setting of the potentiometer R3 indicates the diffusion current. In a modification, Fig. 2, the single resistor R1 is replaced by a fixed resistor R1 and two variable resistors R6, R7 ganged together so that the total series resistance R1, R6, R7 is constant. The values are such that when the portions of R6, R7 in circuit are equal the potential at the junction R1, R7 is that at the junction R, R3. A potentiometer R4 is connected between these junctions, the tapping being connected to the indicator 6. The diffusion current is determined directly from the two settings of the current measuring controls R3, R4. The null point indicator comprises a condenser, a high-speed, relay, a high-gain thermionic amplifier, and a cathode-ray tube, with a low resistance effectively connected between the input grid and cathode of the first valve of the amplifier and brought into circuit by means of a switch. One electrode of the condenser is connected alternately by means of the relay to the two conductors providing connection to the null point indicator in Figs. 1 and 2. The other electrode of the condenser is connected to the input of the amplifier, the output of which is applied to the Y-plates of the cathode-ray tube. The X-plates providing the sweep are synchronized with the relay so that a trace is formed on the screen showing the relative potentials at the ends of the null point indicator. On balance this trace becomes a straight line, and the balance point can be adjusted so as to measure the current corresponding to the maximum size of the mercury drop.
