Title: Arrangement to maintain the frame width when operating the brightness control of a television set
IPC: H04N5/57
Filed: 1962-09-28
Abstract: 1,010,383. Cathode-ray tube circuits. STANDARD TELEPHONES & CABLES Ltd. Sept. 28, 1962 [Oct. 5, 1961], No. 36890/62. Heading H4T. Variation of the size of the raster resulting from adjustment of the brightness control of a magnetically deflected cathode-ray tube V3 (Figs. 1 and 2) and caused by variation of the E.H.T. voltage when the beam current is varied by the brightness control R2, is prevented by varying the E.H.T. in a compensating manner. This is achieved by varying the loading produced by a capacitor C on a winding W1 of the line transformer Tr (from which the E.H.T. is derived), the effect of such loading being to increase the sawtooth fly-back time (and hence reduce the E.H.T. voltage) as the loading is increased, and vice versa. Variation of the loading may be controlled by a potentiometer R1 (Fig. 1) connected in series with C across winding W1 and mechanically linked with the brightness control R2 or, the arrangement shown in Fig. 2, utilizing the latter control alone, may be employed. Specification 708,727 is referred to.

Abstract: 901,578. Sausages; filling and linking. HANDTMANN, A., [trading as HANDTMANN METALLGIESSEREI, ALBERT]. Nov. 2, 1959 [Nov. 5, 1958], No. 37109/59. Class 28 (2). A measuring piston 22 is reciprocated in a cylinder 23 to deliver a predetermined quantity of sausage filling by a crank device driven at a substantially constant speed assisted by an hydraulic driving piston in cylinder device. Operation commences when valve 1 is moved by an elbow lever 2 to full-line position, Fig. 1, where lever 2 is held against spring 3 by a locking pin 59, valve 10 being in the position shown. Oil, drawn in by pump 4, passes through ducts 9 and 11 and pipe 12 into chamber 13 beneath a piston 15 which is connected by a rod 21 to a piston 22. Oil also passes from duct 9 through duct 16 and pipe 17 to the space 18 above piston 15 and to an hydraulic motor 20 of infinitely variable torque. The relative sizes of the surfaces of piston 15 in spaces 13 and 18 are such that under the action of the oil pressure piston 22 tends to rise. An extension 24 of rod 21 is connected by a pin 25 and link 26 to a crank-pin 27 rotating with a crankwheel 28 driven by motor 20. As piston 22 rises, it displaces sausage meat through a duet 32 in a member 31 and a twisting nozzle 33 into a sausage casing carried on a filling tube 34. when piston 22 is in its upper position member 31 is turned through 180 degrees so that duct 32 connects cylinder 23 to delivery cylinder 36. At the same time slide valve 10 is displaced downwardly by a cam 39 rotating with crank-wheel 28 and oil from duct 9 passes to the cylinder space 18 and to motor 20. Piston 22 is moved downwards and oil displaced from space 13 passes through pipes and ducts 12, 11, 40, 41, 42 to a cylinder space 43 to push piston 45 upwards. Connected to piston 45 by a rod 46 is a piston 47 in delivery cylinder 36 which, as it rises, pushes sausage meat through duct 35 and passage 32 into cylinder 23. During this movement, oil above piston 45 is returned to reservoir 6. In a modification, Fig. 3 (not shown), motor 20 is replaced by a piston in cylinder arrangement.

Title: A method of propagating mammalian cells
IPC: C12M3/04
Filed: 1966-08-23
Abstract: A method of propagating mammalian cells in vitro comprises: aseptically planting mammalian cells suspended in a nutrient tissue culture medium within a roller tube, the cells and medium occupying substantially less (e.g. 7% - 15%) than the full volume of the tube; sealing the tube and placing it in an incubator with its longitudinal axis substantially horizontal; revolving the tube at a speed of from 4 to 60 revolutions per hour while incubating it at a temperature of from 35 to 37.5 DEG C. to permit the cells and medium to come into contact with substantially the entire inner surface of the tube; maintaining the pH of the tissue culture medium at between 6.8 and 7.8; revolving the tube in the incubator (e.g. for 5-6 days) until a substantially confluent sheet of cells is formed on the inner wall of the tube; releasing the cells from the inner wall of the tube; agitating the released cells to disperse them into small aggregates of cells; and harvesting the cells.  Before sealing the tube, the gas phase is charged to at least one-third of its volume with a mixture of about 5% CO2 in air, whereby the gas phase of the tube contains from 1.5 to 3% CO2 giving a gas-liquid equilibrium assuring a pH of 7 - 7.8 in the culture medium.  After the confluent sheet of cells has been formed, supernatant tissue culture medium is aseptically poured off from the tube, the cell sheet is bathed in a cell-releasing solution comprising a balanced salt solution containing a small amount of trypsin, tissue culture medium is added to the released cells and then the tube is agitated to free the cell sheet from the tube wall and to disperse the cells into small aggregates of cells. The harvested cells are "split" into a plurality of further tubes. Heteroploid and diploid cells (specified) may be propagated. The roller tube may be 1 - 25 cm in diameter and 62 cm long.

Abstract: 364,311. Thermostats; fireextinguishing; thermal switches; valves. MATHER & PLATT, Ltd., Park Works, Manchester.-(General Fire Extinguisher Co. ; Providence, Rhode Island, U.S.A.) Dec. 17, 1930, No. 33032. [Class 64 (ii).] A heat-sensitive device having a pair of pressure chambers so arranged that the pressure effects balance during a gradual temperature change but not during a rapid change is provided with tubular bellows to transmit the pressure to the part to be actuated, which may be the valve of a fire-extinguishing sprinkler, a remote valve controlling a fire-extinguishing medium, the cover of a tank, or an electric switch. In Fig. 1, the outlet opening of a sprinkler head is closed by a valve 14 pressed by toggles 16, 18 resting on the valve and on an adjusting pin 20. The pressure-transmitting elements comprise tubular bellows 26, 26<1> acting through rods 24, 24<1>, and contained in chambers 32, 32<1> containing a volatile liquid such as ethyl chloride. A slow rise of temperature produces equal pressures on the two bellows, but a rapid rise affects the bellows 26 more quickly owing to the heatcollecting ribs 34, and forces the toggles over the dead centre so that the valve 14 is free to open. Fig. 4 shows the application to the control of a remote valve. The heat-sensitive device comprises a bellows 38 mounted on an annular partition 40 in a vessel 42. The bellows and lower part of the vessel 42 are connected by a restricted opening 50, so that a sudden rise of pressure in the vessel 42 is not immediately communicated to the interior of the bellows which is thus forced upward. The increased air pressure produced in the space 48 is transmitted through pipe 54 to a diaphragm 56 to force the valve 74 away from the partition 68d and against the seating 68b. The valve 62 is normally kept on its seating by an arm 64a carried by a valve 64 pressed on its seating by the supply pressure passing from the pipe 60 through pipe 67, port 68b, and pipe 70 to chamber 72. Movement of the valve 74 as above closes the port 68b and opens the chamber 72 to atmosphere, whereby the supply pressure is free to lift the valve 62 from its seat and allow fire-extinguishing medium to pass to the distributing pipe 78. In another application, Fig. 5 (not shown), the heat-sensitive device is placed in a tank containing inflammable liquid, and the pressure-actuated bellows are adapted, in case of fire, to release a catch and allow the tank cover to fall. Fig. 6 shows the application to an electric switch. The vessel 116 containing volatile liquid is connected to the interior of a bellows 114 by a restricted opening 126, so that only a rapid rise of temperature and pressure in the vessel 116 moves the bellows and rod 118 upward to close the contacts 108, 108a. A shoulder 118a and catch 128 may be provided so that manual release of the switch is required. A small bellows 120 serves as a substitute for a stuffing-box.
