Title: A new or improved electrically heated vaporiser for internal combustion engines
IPC: F02B9/10
Filed: 1921-04-26
Abstract: 182,253. Reed, F. J., and Reed, J. S. April 26, 1921. Heating by electricity.-In Fig. 1 fuel is injected by a nozzle y against an electrically heated bulb g, situated within the combustion chamber of an internal combustion engine. Current passes from the lead through the arm s and the spiral carbon resistance i embedded in insulating material h, to the point k, where it goes to earth. A hot point is formed at k by the bad connection between the bulb and the carbon. When the bulb g attains too great a temperature the rod j, t of which the upper part is copper, in expanding rotates the arm s about its pivot and separates the contacts r and q, thus interrupting the current. Continued expansion of the rod j forces the fibre block z against the ball valve 5, which admits compressed air to cool the device. A similar electric heating device is applied to another type of vaporizer (Fig. 3). The fuel after passing through the coil 24, situated in the exhaust jacket 32, is injected into the helical passage 29, through the nozzle 24a, impinging on the wall surrounding the bulb g at a point opposite the carbon resistance i. Air is drawn in controllable quantities through a valve (not shown) below the fuel nozzle 24<a>. The mixture passes through the helical passage 24 to the chamber 11, in which is provided a piston 15, and thence through the port 16 to the engine. The piston 15 controls the fuel supply by the arm 18 and ball valve 21.

Title: Control apparatus for magnetically focussed cathode ray tubes
IPC: H01J29/46
Filed: 1969-03-07
Abstract: 1,254,888. Image pick-up tubes. R.C.A. CORPORATION. 7 March, 1969 [14 March, 1968], No. 12149/69. Heading H1D. In a cathode-ray tube, such as an image orthicon, provided with a magnetic focusing field causing the beam to define focus nodes and antinodes, first and second deflection means are spaced apart by a distance equal to an odd multiple of the distance d between a node and an adjacent antinode. The tube shown is provided with deflection coils 18-20 for horizontal scanning, the pair 20-21 being spaced by d from the pair 18-19; each pair produces a magnetic field in the same direction, and the effect is that the deflections of the two fields add up but that the transverse velocities imparted to the electrons by the two fields cancel each other. Two pairs of electrostatic deflection plates 27- 29 and 28-30 are also spaced by d so that the transverse velocities cancel but the displacements add up; the plates serve as steering plates to displace the primary and the return beams, the specularly reflected electrons passing through the aperture 64 in the separating plate 62 and the scattered electrons being intercepted by the plate 62 and accelerated into the electron multiplier 34. Pairs of alignment coils 25-26 and 23-24 are spaced apart by the distance d and produce equal and opposite fields; in this case the deflections produced by the two fields cancel but the transverse velocities add up. The tube also includes a pair of steering plates 15 and 17 between which a constant electric field is produced, and a pair of alignment coils 22 and 121 the current through which is adjusted for maximum signal. In another embodiment of the invention plates 27-30 are spaced apart by an odd multiple of d/2 and produce oppositely directed fields. In this manner a transverse velocity component is added to the primary beam and an opposite transverse component to the return beam so that the alignment of the primary beam can be controlled without affecting the alignment or displacement of the specularly reflected portion of the return beam.

Title: Separation of metal ions
Inventor: GEORG-MORAWE HANS
IPC: B01J39/07
Filed: 1963-03-27
Abstract: A method for selectively recovering cations of a heavy metal (i.e. a metal having a specific gravity greater than 4) from a solution containing the heavy metal cations and cations of an alkali metal or of an alkaline earth metal, comprises employing a synthetic cation-exchange resin which has been formed by polymerization or condensation and cross-linking and which has carboxyl groups as cation exchanging groups, selectively to take up the heavy metal cations from the solution by neutral exchange (exchange of a cation other than H+ in the resin for the heavy metal cation), and subsequently eluting the heavy metal cations from the resin. Specified heavy metals are zinc, iron, and copper.  The cation-exchange resin may be one that has been obtained by copolymerizing a monoethylenically unsaturated monomer with a polyethylenically unsaturated cross-linking agent. The resin may be in the alkali metal form or in the alkaline earth metal form.

Title: Improvements in or relating to thermionic amplifiers
IPC: H04B15/00
Filed: 1938-04-23
Abstract: 514,059. Valve amplifying circuits. STANDARD TELEPHONES & CABLES, Ltd., JACOBSEN, B. B., and ROCHE, A. H. April 23, 1938, No. 12196. [Class 40 (v)] In negative feed-back amplifiers in which the phase of the feed-back voltage on the control grid is changed due to the high impedance of the signal source, a second feed-back whose phase is not affected is applied to the screen electrode of the valve. The feed-back voltage derived from the output bridge consisting of resistance R5, R6, R7 and the plate cathode impedance of the valve VI is developed across resistance R8 in the grid circuit of the valve. The resultant feed-back is modified in phase due to the impedance of generator G. The feed-back voltage is also applied via condenser C1, without appreciable phase shift, to the screen grid of the valve. The resultant feed-back effect in the anode circuit is the vector sum of the individual feed-backs and is of more correct phase than that due to the control grid alone. The connections of the generator and condenser C1 to resistance R8 may be made adjustable to vary the relative amounts of feed-back. In a modification, Fig. 2 (not shown), the signal voltage and feed-back are applied to both the control and suppressor grids of a pentode, the auxiliary feed-back being applied to the screen grid.

Title: Trailer vehicle braking systems
IPC: B60T13/22
Filed: 1972-03-17
Abstract: 1370167 Trailer brake valves ROBERT BOSCH GmbH 17 March 1972 [20 March 1971] 12507/72 Headings F2F and F2E A trailer has a braking system having a fluid pressure supply for a tractor and a device to control brake application in the event of trailer breakaway and comprising a change-over valve having a stepped spool, which in one position provides brake control by stressing of a spring device when the trailer is coupled to the tractor fluid supply but in a second position clears the brake pressure medium from the device, and means for moving or permitting movement of the spool from the first to the second position due to trailer breakaway, reapplication of the brake pressure after such occurrence causing the spool to resume its first position for trailer brake release. In Fig. 1, the spool 8 is spring biased to its first position whereby fluid from the tractor 2 stresses the spring device 25 to release the brakes, via passages 5, 22, 21, 19, 19<SP>1</SP>, 23. In the event of breakaway, the spool 8 is pulled against its spring 14, and a ball 14 engages a groove 15 in the spool. In this position, pressure fluid flows from the spring device chamber 23 to an outlet to apply the brakes. Upon reconnection, fluid pressure from the tractor acts on a face of the spool 8 between the stepped surfaces to force the spool to its first position and to retract the ball 16. Alternatively, the spool 8 is held in its first position by a latch bolt 32, Fig. 5, and during breakaway, the bolt is retracted to allow a spring 31 to bias the spool to the second position. Again fluid pressure action in the spool 8 during reconnection replaces the spool. In Fig. 5, the brakes are applied by fluid pressure from the tractor, through passages 22, 40 to a radial port for the wheel cylinders. Fluid also flows through a non-return valve to the spring chamber. Upon breakaway, the spool moves leftwardly, as in either of the two previous examples, to connect the spring chamber-with the wheel cylinders to provide fluid pressure for the brakes. Upon reconnection, fluid is supplied to the spool to move it to its first position, by a brake application on the tractor, and to refill the spring chamber for further possible use.
