Filed: 1956-02-14
Abstract: The evaporator comprises a housing 2 containing a hollow rotor 1 mounted in ballbearings 5, 6 and driven by pulley 19, the interior of the rotor being separated from the housing by sealing means 10. Heating medium such as steam is introduced into the housing through inlet 16 and the condensate is discharged through outlet 17.  The liquid to be evaporated is supplied through pipe 11 to the lower end of the interior of the rotor; and owing to centrifugal force it flows up the hot surface of the rotor in the form of a film and undergoes evaporation.  The vapours pass up the hollow channel in pivot 3, and are discharged through outlet 18. The non-evaporated liquid flows through paring device 12 at the upper end of the rotor, and is withdrawn through pipe 13.  The upper end of the rotor is provided with one or <PICT:0797962/III/1> more conveyer vanes 21 to obviate splashing.  If it is desired to carry out the evaporation under reduced pressure, a vacuum pump is attached to outlet 18.  The rotor can have forms other than that shown; and the surface may, if desired, be corrugated.  The heating medium may be introduced into the housing through a plurality of jets.  The distillation of aromatic and ethereal oils, and the deodorization of vegetable oils, are referred to.

Title: Method and apparatus for setting up a temperature gradient
Inventor: ORECCHIA LUIGI
IPC: G21C17/00
Filed: 1970-01-30
Abstract: 1287516 Induction heating EUROPEAN ATOMIC ENERGY COMMUNITY 30 Jan 1970 [1 Feb 1969] 4657/70 Heading H5H [Also in Division G4-G6] Apparatus for setting up a radial temperature gradient across a hollow member which is a good conductor of heat (e.g., a uranium carbide testpiece, to simulate the thermal conditions of fuel inside a nuclear reactor) comprises a cooling jacket arranged for surrounding the member to cool its external surface and a co-axial electrical circuit the central section of which has a high impedance portion arranged for positioning within the hollow of the member, the remainder of the circuit being of low impedance, so that h.f. alternating current may be applied to the circuit to heat the interior of the member by induction. In the apparatus shown in Fig. 2, housed in a vacuum reservoir in an atmosphere of less than 10<SP>-5</SP> Torr, water travels through the central tube 5 of the coaxial line into an induction coil 3, emerging at the pipe connection 6 and passing down into a cavity 8 formed between two copper containers 9. The water leaves cavity 8 at the top and flows into a space 11 formed between two copper discs 12, after which it flows through piping 13 into a cavity 14 formed between two tubes 15 surrounding the tube 5. The h.f. circuit follows much the same path as the cooling circuit, flowing through tube 5 to coil 3, generating induced currents in the cylindrical testpiece 17, after which it flows through containers 9, discs 12 and tubes 15. An alumina washer 21 having four synthetic resin supports 22 supports the jacket 24 cooling the testpiece 17. The jacket 24, which is made of brass, comprises an annular chamber 25 for cooling water. Twelve holes 28 extend through the body of the jacket 24 to provide space for twelve thermocouples. The cavity 29 inside jacket 24 is covered by a thermal barrier made up of sheets of oxidized Al covered with a thin layer of Al 2 O 3 . Two Al washers 32 are used to centre the coil 3 with respect to the jacket 24 and testpiece 17. A window 30 in the containers 9 and a window 31 in one of the washers 32 can be used for making external measurements with a photometric-type pyrometer of the radial temperature of testpiece 17. Coil 3 is made of a tube of annealed Cu having a rectangular crosssection. An Al 2 O 3  rod (not shown) is introduced into the central aperture of the coil to increase its mechanical strength, and the aperture is then plugged at both ends in vacuo by brazing two brass plugs. Finally the coil is welded on the tube 5. A thin insulating layer of Al 2 O 3  is applied to the outer surface of the coil. The testpiece 17 may, for example, be heated internally to 1300 C. and cooled externally to 450 C.

Abstract: 967,750. Multipled radio signalling. TESLA, NARODNI PODNIK. Feb. 7, 1962 [April 6, 1961], No. 4698/62. Heading H4L. In an arrangement for supplying signals from a vision transmitter and a sound transmitter to a common output feeder, the vision transmitter is connected via feeder 1 to parallel connected output amplifiers 4, 5 spaced by a quarterwavelength, the outputs of the amplifiers being supplied to points 10, 13, respectively, of a hybrid network 14, and the combined output being taken via a feeder 15 to the aerial. Resonators 8, 9 are connected to block the sound signals but allow the vision signals to pass. The sound signal is applied via line 22 to point 11 of the hybrid 14. Resonator 19 is connected to block the vision signals and pass the sound signals and any sound signal reaching point 17 is by-passed from resistor 21 by a resonator 20 tuned to the sound signal frequency. Sound signals are reflected at points 6, 7 and due to the quarter-wave spacing of resonators 8, 9 appear in phase at the output feeder 15. Reflections of the vision signal from the output circuit are reflected back in phase to the point 16 by the high impedance presented by the amplifiers 4, 5, and their quarter-wave spacing, and absorbed in resistor 21. Should one of the amplifiers 4, 5 fail, the output of the remaining amplifier will be divided equally between the resistor 21 and the aerial feeder 15.

Abstract: 397,146. Metal-working presses. GLASNER, R. W. and RODE, F. J., 6500, West 65th Street, Chicago, U.S.A. Feb. 18, 1932, No. 4787. [Class 83 (iv).] A metal-working press such as a riveting, swaging, or embossing machine comprises a movable lower die 18 which, when a predetermined pressure is exceeded, may yield against hydraulic pressure, the fluid being supplied from a hydro-pneumatic reservoir 39 forming an integral part of the machine. The die 18 mounted on a support 13 co-operates with an upper die 19 carried on a reciprocating slide 32 which is secured by rods 31 to a head 30, operated through a link 29 from an eccentric 27 on a shaft 21 driven by gearing 22 .. 26. The support 13 is mounted on a piston rod 16 secured to a piston 15 working in a cylinder 14 to which fluid may flow from the reservoir 39 through a pipe 42 and spring-seated valve 46 thus maintaining the piston normally in its raised position. A passage 50 from the cylinder communicates through a valve 55, guided by a piston section 56 moving in a member 53, with a passage 43 leading through the pipe 42 to the reservoir. The valve 55 is connected to a stem 57 terminating in a cylinder 59 having a hollow stationary piston 62 connected to a frame 60, 61. The cylinder 59 is supplied by a pipe 63 provided with a regulating valve 64, pressure gauge 65, and check valve 66. A branch 67 from this pipe also supplies fluid to the reservoir 39 and is fitted with a pressure gauge 69 and with regulating and check valves 68, 70 respectively. In operation the valve 55 is normally held on its seating by pressure in the cylinder 59, but when the pressure on the lower die causes the pressure in the cylinder 14 to exceed that in the cylinder 59 the valve 55 is unseated and fluid escapes from the cylinder 14 and flows back to the reservoir along the pipe 42. When the upper die is raised the relief of the pressure on the lower die causes the valve 55 to close while valve 46 opens and fluid flows into the cylinder 14 to raise the piston 15 and die 18 to the normal position. When desired the piston rod 16 may be locked and the cushioning device thus rendered inoperative.

Title: Apparatus for reproducing television pictures
IPC: H04N5/74
Filed: 1959-02-13
Abstract: 861,408. Television. GRETENER A. G., E. Feb. 13, 1959 [Feb. 25, 1958; Dec. 19 1958], No. 5135/59. Class 40(3) [Also in Group XL(a)] In the reproduction of television pictures by means of a schlieren optical system containing a deformable film controlled by a scanning electron beam, the beam is controlled so that the charge pattern laid down along the picture lines varies in width across the lines point-by-point in accordance with the video signal, the width being greater the lower the brightness of the picture point. The effect of the invention is illustrated in Figs. 3 and 4 for a series of parallel lines 50. Region 51 represents a " black " region where the lines are controlled in width so that they merge to produce a uniform charge distribution with no resulting deformation of the medium, and regions 52 and 53 represent typical picture detail regions where the lines vary in width in accordance with the video signal and result in corresponding deformation of the medium. To allow for the falling off of charge density at the edges of the lines, they are preferably caused to overlap in " black" regions, as shown at 57, so as to produce a uniform overall charge distribution. The bars and slits of the Schlieren optical system are orientated parallel to the scanning lines. The variation in the width of the charge laid down may be effected either by varying the focus of the electron beam or "wobbling" the beam at a high frequency transverse the lines with an amplitude controlled by the video signal. In one way of varying the beam focus, Fig. 6, the electron beam 75 (at a position between the anode of the electron gun and the normal focus coil, Fig. 5, not shown) is passed through an electron-optical system comprising two pairs of rods 80 and 84 disposed parallel to the beam. The pair 84 is maintained at anode potential, whilst the pair 80 is given a negative bias of 20 volts with respect to anode potential and also supplied with the video signal which is positive going with a maximum amplitude of 20 volts. The system causes axial astigmatism of the beam creating two spaced linear images which are separated by a beam having, at the locus of the original spot of the focused beam, an approximately circular section of a diameter roughly proportional to the video potential applied to pair 80. Specification 678,307 is referred to.

Abstract: 714,527. Horticultural shelters. BELL, O. H. Feb. 27, 1953 [Feb. 27, 1952], No. 5149/52. Class 20 (1) Growing crops are covered by glass or like panels (e.g. Dutch Lights) mounted in pairs between adjacent pairs of spaced channel form gutters, supported above the ground, so as to form pitched roofs, the lower ends of the panels having projections thereon which hook under overhung projections on the walls of the gutters so that the panels are prevented from being lifted by the wind but may be slid along on the gutter walls. As shown, gutters 2 are formed by channel lengths 4, having inturned edges 18, forming overhung projections whose ends are bolted to steel plates 5 on the top of tubular legs 3 whose flattened lower ends 24 are sunk into the ground. Welded near the lower end of each leg is a collar 25 which engages a concrete block 26 resting on the ground. Steel strips 7 maintain alignment of the channel lengths 4. Trusses, comprising two angle section members 8 and horizontal ties 9, are bolted to pieces of steel near the ends of the lengths 4, Fig. 4, and adjacent trusses are joined by angle section lengths 12 bolted to their apices. This structure forms a support for Dutch Lights. One end of each light carries a hook member 19 which is engaged with one of the edges 18, Fig. 6, and then the light is rotated so that it is held in position, Fig. 3. The upper end of the light is held by a turn button 17 secured to the light by a bolt 16. Other lights may carry hook members 33 to engage the outer wall of the gutter, Fig. 7, and so enclose the sides of the structure. The lower ends of these sides are he'd by pegs 34.
