Title: A process of cultivating the micro-organisms parasitically vegetating in human and animal bodies and of preparing immunising sera therefrom
IPC: C07K16/30
Filed: 1927-07-11
Abstract: 304,155. Schmidt, W., and Schmidt Serumwerk Akt.-Ges., W. July 11, 1927. Bacteria, cultivating; vacines and immunizing and like serums. - Micro-organisms causing malignant tumours, such as carcimona, are cultivated, either in vitro or in vivo, in symbiosis with mould fungi such as Mucor Racemosus or Mucor Mucedo, and vaccines and immunizing preparation are obtained from the organisms so cultivated. The cultures in vitro are made in media containing sugar and at temperatures below blood heat. Suitable media are (1) peptone-sugar broth containing 1 per cent glucose, 2 per cent peptone, and 0.5 per cent Liebigs meat extract, and (2) pea-sugar-agar broth containing 2 per cent glucose, 2.5 per cent agar, and 0.5 per cent Liebrigs extract dissolved in a 25 per cent aqueous pea broth. Commercial grape sugar is used in preference to pure sugar. Mixed cultures from artificial media, or the micro-organisms and moulds separately, may be injected into animals and again obtained from the blood or animal organs. Withdrawal from the animal within 3 to 5 days yields the two organisms in symbiosis' whereas after a longer period the tumour organisms only are obtained as a pure culture. Cultures may also be made in collodion tubes in the peritoneal cavity of an animal and cultures in artificial media may thus be rendered more virulent. Pure cultures of the tumour organisms may be obtained from a mixed culture in artificial medium by mechanical treatment such as shaking, or by heating to a temperature between 28‹ and 40‹ C., or by treatment with alkalies, soap, saponin, or weak acid, or by a combination of such treatments, so as to break up or destroy the fungus structure and release the contained tumour organisms into the surrounding liquid which may then be used for immunization purposes or for further cultivation. Moulds containing the tumour organisms as parasites may be removed from the culture medium, suspended in a suitable liquid and treated mechanically, chemically or by heat or by two or more of these processes to release the parasites, which are partly brought into solution and partly remain as such. The liquid is then centrifuged or filtered, and serves as a vaccine. Mixed or pure cultures of the tumour organism may be inoculated into animals for the purpose of obtaining serum containing antibodies from the blood or organs of the animal. Pure cultures of the organism may be cultivated in artificial media at blood heat in open flat dishes. Specification 29588/04 is referred to, and a known process is described wherein tumour organisms and lower plants are cultivated in symbiosis in media not containing sugar.

Title: Improvements in particle study or detecting apparatus
Inventor: JR JOSEPH RICHARD COULTER
IPC: G01N15/12
Filed: 1959-06-02
Abstract: 903,156. Electric selective-signalling systems. COULTER ELECTRONICS Ltd. June 2, 1959, No. 18847/59. Class 40 (1). [Also in Groups XXVIII and XXXVI] Apparatus for detecting particles suspended in a fluid medium comprises a hollow body having an orifice submerged in a vessel and having a solid member engaged with the fluid in the hollow body to provide fluid flow through the orifice in a volume related to the displacement of the member and means operated by the displaced member to initiate the detection of particles. Fig. 1 shows a beaker 34 containing the liquid under test in which is submerged an orifice 42 in a tube 38 also containing the test liquid. The piston 76 is first displaced in an upward direction under control of the vacuum control valve 66. When valve 66 is closed the weight 92 will operate a rack and pinion 80, 86, withdrawing the piston 76 and causing a flow of test liquid through the orifice 42. When a particle passes through the orifice 42 a change in liquid conductivity is observed by the detector 10, which supplies a constant current or constant voltage to electrodes 58, 60. A switch 98 is operated by projection 96 to initiate the start of a countercontained in apparatus 10. The counter is stopped by projection 96, engaging switch 100 after a predetermined quantity of liquid has passed through the orifice. In Fig. 2 (not shown), the projection 96 is replaced by a contact on the piston, engaging contacts let in to the wall of tube 74. Fig. 6 (not shown), relates to an embodiment for metering very small volumes of liquid. The piston is formed by a thin rod passing through a seal located in tube 74. Fig. 5 shows an arrangement for testing corrosive liquids in which a flexible diaphragm is interposed between the test liquid 56 and the metering pump contained in tube 186. The piston 188 is lowered under the control of vacuum control valve 194. When valve 194 is closed the piston 188 is raised by motor 210 drawing the tested fluid through the orifice. Modifications.-The vacuum valve 66 may be controlled automatically by the start/stop signals. Suction or pressure may be applied to the tested fluid and the piston 76 used only as a passive metering device. Locating conductive pistons.-In Fig. 7 a solid metallic piston 230 may be used, start and stop indications being respectively provided as the piston passes between the pairs of electrodes 222, 224 and 226, 228, thus varying the capacitive coupling or frequency of oscillators 160, 164. In Fig. 3, the start and stop indications are provided as conductive loops 150 pass between pairs of coils 152, 154 and 156, 158. The coils of each pair are connected respectively in the anode and grid circuits of an oscillator so that oscillation is only commenced in the presence of the conductive loop 150. Fig. 4 (not shown), relates to coil construction.

Title: Improvements relating to stop valves for fluid under pressure
IPC: F16K17/00
Filed: 1931-06-30
Abstract: 379,038. Fluid - actuated valves. THOMAS, J. H., 49, Ryecroft Road, Stretford, Manchester, and ASSOCIATED ELECTRICAL INDUSTRIES, Ltd., Crown House, Aldwych, London. June 30, 1931, No. 18916. [Class 135.] A stop valve particularly adapted for use in installations where steam is extracted from an intermediate stage of a reducing pressure, pass-out or other turbine, is biased to its open position and is closed by the application of a strong force such as a weight or spring released by a catch held in position by fluid pressure against the action of a spring. This pressure may be derived from the turbine oil pump and may be released by the turbine overspeed emergency governor. The closing weight 5 slidable in guides 6a is lifted to free the valve spindle and allow the main valve to open by admitting fluid pressure through a pipe 21 to the underside of a piston 8 secured to the weight by a spindle 7. And is retained in its raised position by a sliding catch 10 moved into position beneath the weight against the action of a spring 21 by fluid pressure acting on a piston 13 mounted with lost-motion on a reduced part 11 of the catch. The piston is formed with a seating surface 22 and with recesses 20 adapted to co-operate with a valve seat 18 and with ports 14 .. 17 in a liner 131 so that when pressure fluid is admitted through port 19 it first passes through passages 20 and ports 15, 17 to actuate the piston 8 and afterwards as the pressure rises it moves the piston 13 to actuate the catch and connects the space below the piston 8 to exhaust through pipe 21 ports 15, 16, 17 passages 20 and port 23.

Title: Improvements in the dehydration of moist fuel
IPC: C10F5/00
Filed: 1927-07-18
Abstract: 274,858. I. G. Farbenindustrie Akt.- Ges. July 21, 1926, [Convention date]. Mineral tar oils, purifying; recovering waste lubricants.-Moist fuels such as brown or other coal, peat, wood, tars, and mineral oils, are dried by heating to above 200‹ C. under pressures preferably so high as to maintain the moisture liquid, and running off the separated water. Solid fuels are treated as pastes with other fuels which are liquid at the temperatures used. The operation is facilitated by operations such as stirring, centrifuging, intermittent motion, action of an electric field, or addition of agents influencing the surlace tension of water, e.g. aniline or sulphonic acids or sulphonates of aromatic or hydroaromatic compounds containing alkyl groups; it may be continuous or may be repeated. Such fuels are particularly suitable for destructive hydrogenation.. In an example, crude brown coal tar, or crude brown coal mixed with an equal weight of tar, is heated to 320‹ C. under 200 atmospheres pressure. Immediately after the water settled out has been drawn off the hot fuel is destructively hydrogenated by treatment with hydrogen under pressure.

Title: Television tuner circuits
IPC: H03H2/00
Filed: 1971-06-07
Abstract: 1312418 RF couplings; television tuners; automatic gain control PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 7 June 1971 [6 June 1970] 19168/71 Headings H3T and H4A An input circuit for a television tuner which includes aerial terminals 1, 2 and a transistor 9 in common base configuration, is characterized by shunt- and series-connected PIN diodes 6, 7 and associated means whereby direct currents are applied thereto which respectively increase and decrease as the input signal intensity increases. Consequently, the signal frequency output impedance of the attenuator formed by the PIN diodes, which impedance is the source impedance for the transistor, increases as the input signal intensity increases. As described, the cathodes of the PIN diodes 6, 7 are connected together and are coupled through a resistor 4 and a capacitor 5 to the aerial terminal 1. The purpose of the resistor 4 is to reduce the standing-wave ratio at the aerial terminals. Resistors 15, 16 are respectively connected between the commoned cathodes of the diodes and earth, and between the anode of the diode 7 and earth. The emitter of the NPN transistor 9 is connected to the anode of the diode 7, its collector being connected to a tunable output circuit 13, through which positive voltage is supplied. A positive bias voltage is applied to the anode of the diode 6 by means of a potentiometer arrangement comprising resistors 22, 23, and A.G.C. voltage is applied to the base of the transistor 9. The aerial terminal 2 is earthed, and leadthrough capacitors 19, 20, 21 are provided for the connections to the transistor 9, the resonant circuit 13, and the diode 6. With a weak input signal, the A.G.C. voltage is high, and a relatively large current, for example, 7mA., flows through the transistor. Of this current, 4 mA. may flow through the resistor 16 and 3 mA. may flow through the diode 7 and the resistor 15, while the diode 6 is substantially blocked. With a strong input signal, the A.G.C. voltage is reduced, and the transistor emitter current may fall to 3 mA. The corresponding current through the diode 7 may be substantially zero, while a current of 2 mA. may flow through the diode 6. In order to obtain an optimum signal-to-noise ratio the PIN attenuator is so proportioned that its output impedance when there is a low input signal is less than the optimum noise impedance of the transistor, but exceeds it with increasing input signal intensity. If the transistor 9 is of PNP type, the circuit shown in Fig. 2 is modified by connecting the lower side of the resistor 16 to the positive voltage supply, and the lower side of the circuit 13 to earth. In another embodiment, the A.G.C. voltage is connected through the resistor 16, and fixed negative and positive biasing voltages are respectively connected to the resistor 15 and to the base of the transistor 9 (Fig. 1, not shown).

Abstract: 485,252. Feeding sheets. BATTEY, A. P., and BACKHOUSE, H. T. July 12,1937, No. 19281. [Class 100 (i)] A device for side-registering sheets; which is especially applicable to overlapping stream feeds, of the kind in which the sheets are pulled against side lays by a reciprocating gripper is so constructed that both the opening and closing movements of the gripper are effected during the movements of the gripper in the direction towards the stop. In one form, Fig. 1, the gripper is carried by a reciprocating bar 3 and comprises a fixed member 1 and a pivoted member 2 acted upon by a spring 5 which tends to close it. As the gripper moves away from the lay 6 an adjustable arm 10 on a shaft 7 acts on a roller 11 carried by the arm 2 and maintains the gripper open. The shaft 7 is rotated by a cam and a rod 13 and arm 12 as the gripper moves towards the lay and permits the spring 5 to close the gripper. Finally the shaft 7 is returned to open the gripper at the time that the sheet reaches the lay 6. A rotary cam acting direct on the roller 11 may replace the oscillating arm 10. In Fig. 3, the gripper member 2 is controlled by toggle links 31, 32, which occupy the chain position as the gripper moves away from the stop. As the slide returns a pivoted pawl 22 operates the toggles and moves them to the full line position and the gripper 2 closes on the sheet. A fixed stop 34 finally opens the gripper 2 as the side lay is reached. In a further modification the gripper 2, which is opened by a fixed cam as the side lay is reached, is held open by a spring-controlled catch until the slide 3 commences to move towards the lay, when the catch is released by a pawl 22. Specification 427,041 is referred to.
