Title: Improved method of and apparatus for converting milky liquids, solutions, dispersions and emulsions into powder form by spray drying
IPC: A23C1/04
Filed: 1932-10-13
Abstract: <PICT:0396579/III/1> Solutions and emulsions, e.g. milk, are converted into dry powder by spraying them centrifugally into a heated stream of gas so that the gas together with the sprayed liquid moves upwardly through the drying chamber and dries and carries off the particles simultaneously.  The liquid is fed from a tank 1 through a pipe 2 to a funnel 8 rotating on a shaft 5.  Air supplied through a pipe 9 and given a rotatory upward movement through a coneshaped chamber 10 by a fan 12 mounted on the rotating shaft 5, carries the liquid sprayed from the funnel 8 with it through an annular chamber 14 formed by an inner chamber 13 and a similarly shaped outer chamber 11 to which the inner chamber is fixed by ribs. The vapour, air and dried powder are drawn off by a fan 15 into a filtration chamber 16 provided with a filter 17 and the powder is removed by a conveyer 19 and outlet pipe 20, the air and vapour being removed by a fan 18.

Title: An improved manufacture of gasoline and like hydrocarbons
IPC: C07C2/62
Filed: 1939-10-24
Abstract: 535,975. Gasoline. STANDARD OIL DEVELOPMENT CO. Oct. 24, 1939, No. 28615. Convention date, Dec. 7, 1938. [Class 2 (iii)] In order to obtain a gasoline of full boiling range the unsaturated C9 heavier fraction of the hydrocarbons produced by the catalytic alkylation of isoparaffins with low boiling olefines is reacted with low boiling aromatic hydrocarbons and the resulting alkylated aromatic compounds blended with the lighter C5-C8 fraction of the hydrocarbon products. In a modification, two reaction zones are provided, the heavier C9 fraction from the first being led to the second zone, which also receives aromatic hydrocarbons. In the Figure, reaction zone 1, filled with sulphuric acid, receives olefines through pipe 4 and isoparaffins through pipe 5. The reaction products in part pass through pipe 10 to settler 12, provision being made by pipes 13 and 15 for recycling the reaction mixture and acid as required. Hydrocarbon products pass through pipe 16 to return header 17 or to stabilizer 22 which enables the C4 hydrocarbons to be separated before the products are fractionated in the fractionator 26. In the latter, the C5-C8 hydrocarbons are expelled in the vapour state and the C9 products leaving by pipe 28 enter the second reactor 30. Feed pipe 5 is connected to the inlet of reactor 30 and is also provided with a branch line 32 for the introduction of aromatic hydrocarbons, and olefines. if desired. Reactor 30, like reactor 1, is filled with acid and the products are discharged through pipe 33 to a settler 34. Acid from the latter passes through drain line 39 to a return header 37 and the hydrocarbons pass in part to a fractionator 44 through pipe 43 and in part to the return header 37. Products boiling between 270 and 410‹C. are withdrawn through pipe 46, low boiling products are either passed to the return header 37 or if suitable are returned through pipe 48 to the C5-C8 fraction. Heavy fractions are also passed to the return header 37. The Specification as open to inspection under Sect. 91 comprises also the treatment of unsaturated C9 and heavier fraction with isoparaffins to obtain a product suitable for blending with the lighter C5-C8 fractions. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to telephone systems
IPC: H04Q3/00
Filed: 1923-11-13
Abstract: 216,088. Automatic Telephone Manufacturing Co., Ltd., (Assignees of Ostline, J. E.). May 14, 1923, [Convention date]. Automatic and semi-automatic exchange systems.-A restricted-service subscriber A is provided at the sub-station with a device S which responds to a momentary increased current sent back over the line 11, 12 from a repeater R when a call is made to a trunking-operator O, and by grounding one of the speaking leads causes the lighting of a lamp L<2> to notify to the operator the character of the calling line. The sub-station of an unrestricted subscriber is not fitted with such a device, and in this case lamp L' islit. The invention thus permits the restrictedservice feature to be applied to some only of the stations on a party-line or to particular extension stations. In the example shown, the device S comprises a core fitted to the usual induction coil 6 and an armature 8 mounted on an adjustable contact spring 40. When the subscriber A calls the operator O, his line is connected in known manner over his line-switch C and thetenth level of a group selector E to a repeater R at which relays 101, 104 energize. Slow-release relay 103 energizes to open contact 121 and to complete a circuit for relay 102 which opens the circuit for relay 103. Relay 102 also opens contact 116 so that during the interval before relay 130 releases its armatures, battery B is connected in series with the exchange battery over the circuit 101, 126, 112, B, 111, 125, 97, 12, 11, 99, 104. Contacts 7 are closed in response to this increased current, thereby connecting direct ground to conductor 12 so that relay 104 is shortcircuited and, on releasing, completes a circuit for relay 106 which locks up. Relay 106 reverses the normal battery and ground connections over the impedance coil 107 to the outgoing conductors 211, 212, so that when, upon the complete release of relay 103, relay 105 operates, polarized relav 201 responds and lights the red lamp L<2>. When the operator O is called by an unrestricted subscriber, relay 104 is not shortcircuited, no circuit is completed for relay 106 and the polarized relay 201 lights the white lamp L<1>.

Title: Improvements in or relating to colour television or like systems
IPC: H04N1/64
Filed: 1947-10-30
Abstract: 638,590. Television. CINEMA-TELEVISION, Ltd., and JESTY, L. C. Oct. 30, 1947, No. 28992. [Class 40 (iii)] In a colour television system in which the picture is reproduced from three or more separate component colour images at least one of which is brighter than the remainder, flicker effect is avoided by alternating the scanning of the brighter component or components with the scanning of each of the duller components. For a three-colour system employing red, green and blue component colours, the scanning sequence is red-green-blue-green, the green component being brighter than the other components. With this particular colour arrangement the red and blue components are made twice as bright in relation to the green as they would be in a conventional scanning sequence. Four colour systems employing a scanning sequence of component colours red-yellowviolet-green, the green and yellow being the brighter components and red-green-bluecyan with green and cyan as the brighter components are also described. The scanning may be sequential, but is preferably interlaced, using a triple interlace of four colour components. The field frequency should be an even multiple of the mains frequency.

Title: Improvements in or relating to high-activity cells
Inventor: BONNET GEORGES
IPC: E06B5/18
Filed: 1960-08-22
Abstract: The inspection window of a cell in which glass-opacifying radiations are being emitted comprises two identical glass slabs 6, 7, assembled edge to edge; two screens of a thickness such as to reduce the radiation level to below an opacification threshold are arranged one on either side of a window opening; the two glass slabs can be reciprocated as a unit so that first slab 6 is in front of the window opening while slab 7 is located between a screen and the cell wall, and then vice-versa. The slab which is in front of the window opening gradually discolours due to radiation, but while it is in its displaced (i.e. screened) position, it gradually regenerates. Fig. 1 shows the concrete wall 1 of a cell in which radioactive processes are taking place, and having a window which comprises fixed glass slabs 2, 3, 4, and a movable slab which is formed by two glass plates 6, 7 placed edge to edge. These can move laterally within a slot 5, <PICT:0942954/C1/1> so that one or other is in the path of the radiation f.  The one which is not so exposed is behind a lead screen 8 or 9. While, as shown in Fig. 1, the plate 6 is exposed to direct radiation, which is of sufficient intensity to cause discoloration, the already discoloured plate 7, protected by screen 9, regenerates in situ. This regeneration is accelerated if the plate is also heated by suitable means.

Title: Improvements in magnetic metal forming devices
IPC: B21D26/14
Filed: 1959-08-26
Abstract: 896,923. Stamping; forging; welding by pressure; jointing. GENERAL DYNAMICS CORPORATION. Aug. 26, 1959 [Aug. 28. 1958], No. 29207/59. Class 83 (4). A method of forming metal, e.g. stamping, embossing, upsetting and welding, comprises setting up a predetermined varying magnetic field and maintaining a metal workpiece to be formed within the magnetic field so that sufficient energy is transferred from the magnetic field to the metal to form the metal in the desired manner. In an embodiment for necking a copper or aluminium tube 20 the varying magnetic field is set up by passing a current pulse through a coil or solenoid 11 surrounding the tube by means of a high capacity condenser 13 in series with switching means 14, e.g. an ignitron, thyratron or spark gap. The tube is held in clamps 21. When a current pulse is applied to the solenoid a varying magnetic field is set up which induces an electromotive force in the workpiece which, in turn, causes a high current to flow around the workpiece. The interaction of the induced current and the magnetic field causes the workpiece to be deformed. A die (not shown), may be inserted in the workpiece to define or limit the deformation. In another embodiment two tubes or a tube and a rod are crimped together by passing a current pulse as hitherto through a loop 22 (Fig. 3). A plurality of spaced loops 22 are used for forming a series of crimps or corrugations in a tube. In another embodiment for impressing a pattern into the surface of a flat metal sheet, the conductor 27 is wound on to a spiral and a die 28 is adjustably supported above the conductor. The metal sheet is placed between the conductor and the die so that when the electromotive force is generated the sheet is forced against the die and the die pattern is embossed on the sheet. In a further embodiment a metal tube is corrugated by placing the tube in a split die 34 having internal corrugations and inserting within the tube a conductor 33 which is supplied with a current pulse to effect the corrugating operation. The spiral type conductor may be used to surface weld a metal sheet to a non- metallic sheet.
