Patent GB-109462-A (GB)
IPC: F02M25/022
Abstract: 109,462. Noble, J. Aug. 14, 1916. Vaporizers, external.-Heavy-oil fuel from a float chamber A is vaporized in a coil C heated by exhaust gases passing along the pipe E and the vapour is discharged through a jet G into a chamber H communicating at H<1> with the motor. Primary air is admitted at H<2> and supplementary air at H<3>. For starting the engine, the fuel is heated electrically at O. Water from a float chamber Q is vaporized by means of a coil P and discharged at S. To regulate the temperature, as when ordinary petrol is used, the exhaust gases may be diverted into a by-pass pipe L by means of a valve L<1>.

Title: Improvements in or relating to velocity-modulated electron discharge tubes
IPC: H01J25/10
Filed: 1945-12-20
Abstract: 640,747. Velocity-modulated tubes. PHILIPS ELECTRICAL, Ltd. Dec. 20, 1945, No. 11044/48. Convention date, Dec. 2, 1940. Divided out of 640,697. [Class 39 (i)] In a tube of the type in which the electron beam from cathode 3 and anode 4 passes a first time through a control electrode system 6, 7a, 7b, 8 in which it is velocity-modulated, is reflected by a brake-field electrode system becoming bunched, and passes a second time through the control electrode system to deliver energy to it, the brake field system comprises two electrodes 10, 14 at such potentials that the electric field strength in part of the brake field is considerably weaker than the field strength near the control electrode system. As shown, electrode 14 is a cylinder at cathode potential and electrode 10 is a plate at the far end of the cylinder and at a more negative potential. Specification 640,697 is referred to.

Patent GB-494098-A (GB)
Title: Improved process and apparatus for increasing the energy of a stream of gases containing carbon monoxide and/or other burnable gases by combustion thereof in the presence of a contact mass or catalyst
IPC: F23G7/07
Filed: 1937-04-19
Abstract: 494,098. Consuming fumes and gases. HOUDRY PROCESS CORPORATION. April 19, 1937, No. 11119. Convention date, May 8, 1936. [Class 51 (i)] Gases containing carbon monoxide or other combustible fluid, such as fumes from the regeneration of catalytic material in converters for the treatment of hydrocarbons, are passed through a combustion zone containing contact or catalytic material where they are oxidized, and leave the combustion zone at a temperature not exceeding 1200‹ F., heat being withdrawn from the combustion zone by the gaseous stream prior to entering such zone. The gases may be at superatmospheric pressure and after leaving the combustion zone may be utilized for power purposes. Fig. 1 shows one form of apparatus for treating the gases which are supplied through a pipe 11 with or without air, water or fuel to a coil 11a surrounding the combustion tube 5 containing the contact or catalytic mass m. The gases enter the base of the tube 5 which is secured to headers 6, 7 and enclosed by a casing 14 and insulating-material 16. The coil 11a may increase in diameter or the pitch of the coil may decrease towards the lower header to secure a progressive pick-up of heat by radiation from the walls of the combustion tube. Alternatively, the coil may have plates of increasing size attached thereto to increase the heat absorbed. Air may be added to the stream through a pipe 31 adjacent the inlet 10 to the combustion tube. Fig. 4 shows a modification in which the gas is supplied to a chamber 25 from which it passes into the contact or catalytic material m in a chamber 20 through tubes 27a discharging at the lower end of perforated tubes 27b closed at their ends and provided with internal baffles 27c, 27d. The gases leave the combustion zone through perforated pipes 28 and chamber 26. When the gases enter at a temperature of 1000‹ F. or more and contain sufficient oxygen, the contact mass may consist of highly porous material such as pumice, kaolin, firebrick and other blends of silica and alumina. If the gases are at about 900‹ F., the contact mass may consist of metallic oxides and compounds including those of copper, iron, cobalt, nickel and lead. Metals may be used in the form of turnings, or metals and metallic compounds may be finely divided and incorporated in supports of silica and alumina. Where the gases are below 900‹ F., air or other oxidizing medium is added to them. Specifications 6732 /12, 276,300, [both in Class 51 (i)], 414,779, 423,866, and 487,785, [all in Group III], are referred to.

Abstract: 1,175,677. Knitting. S. A. MONK [SUTTONIN-ASHFIELD] Ltd. 8 March, 1967 [15 March, 1966], No. 11276/66. Headings D1C and D1K. A flat twin bed machine has a secondary needle selection mechanism for each bed which overrides the main selection and is adjustable along the length of the beds to be adjacent selvedge needles, so that a plain border is produced on a patterned fashioned blank. The main needle selection mechanism comprises hydraulically operated plungers 18 which raise jack butts 15 into the range of a cam lock, as described in Specification 1,029,871. In one embodiment the secondary selection mechanism comprises plates 36, 37 mounted on housing 27, coupled to rotatable shaft 28 by linkage 33-5. Rotation of shaft 28 is controlled by a hydraulic or pneumatic ram 30. The blades are thereby selectively engageable with the selvedge jacks to move them into or out of engagement with the cam lock. The secondary mechanism is adjustable along the bed by the yarn guide limit screw mechanism. In another embodiment (Figs. 6, 7 not shown), for varying the border width, the lower blade is replaced by a series of pivoted levers (44) and the mechanism is displaceable relative to the fashioning device (22) which prevents selection of jacks at the ends of the beds. A displaceable ram 49 is mounted in the housing to raise needles whose loops will be taken by the fashioning points.

IPC: F26B23/02
Abstract: 115,193. Schlatter, J., and Frorath, R. Nov. 5, 1917. Chambers. - Relates to apparatus for drying fruits, vegetables, cosmetics, dyes, &c. Hot gases and cold air are supplied through separate conduits to a number of drying chambers separated from each other, the admission of the gases and air being controlled by means of a single register for each chamber so that the temperature can be controlled. Fresh air admitted to the pipe 1 passes to a casing 25 enclosing a furnace, the products of combustion from which and the hot air passing outside the furnace are delivered by a fan 33 into a lateral conduit 5 communicating with a conduit 6 and thence pass to the drying-chambers III-XII partly through mixing chambers 10 and partly through openings 20. Cold air admitted to the pipe 1 is driven by a fan 2 through the pipe 3 into the conduit 7 which also communicates with the mixing chambers 10. The conduits 6 and 7 are separated by a partition 8. Each chamber is divided into two parts and is fitted with a sliding plate 16 provided with a counterweight 19, Fig. 5 The plate has openings 20 which admit hot air to the two parts of the chamber through passages, and a larger opening 21 through which hot gases and cold air pass into the mixing chamber 10. By raising or lowering the plate, the supply of cold air or of hot gases may be reduced or entirely cut off. Air is discharged from the chambers through openings 15, Fig. 1, communicating with an upper conduit 13. Doors 22 are provided at the backs of the chambers.
