Title: Improvements in and apparatus for the conversion by heat treatment of coals, tars, mineral oils and the like
IPC: C10G1/06
Filed: 1930-04-28
Abstract: In preheating distillable carbonaceous materials, with or without hydrogen, by passage through an electrically heated tube, the supply of heat to successive portions of the tube is reduced as the temperature of the materials rises in the direction of flow; preferably the temperature of the materials at the outlet is not more than 20 DEG  C. below that of the tube.  The electric current may pass through the material of the tube or through wire resistances wound round it.  The reduction of heat supply may be effected by change in the cross section or length of the wires, or by the application of different voltages at suitable points.  The preheating tube may be arranged inside a reaction vessel.

Title: Electric-discharge system
IPC: H05B41/32
Filed: 1960-08-16
Abstract: 900,324. Charging and discharging capacitors. EDGERTON, GERMESHAUSEN & GRIER Inc. Aug. 16, 1960 [Sept. 17, 1959], No. 28431/60. Class 38 (4). A circuit for producing flashes of light in a discharge tube 3 comprises a series-connected capacitor bank C1, C7 charged from an A.C. source ABC through a self-excited parallel transductor T1, transformer P1-P3, S1-S3, bridge-connected rectifiers CR9-CR14 and conductors B+, B-. The tube 3 is triggered by another tube 9. By grounding an auxiliary electrode 10 through a switch 5 a capacitor C14 discharges through a primary winding L1, thus a pulse of, say, 15 k.v. is applied to a trigger electrode 4, which together with an additional potential from another secondary winding L3 causes the capacitors 1, 7 to discharge through the tube 3. The capacitor bank voltage is regulated by a circuit comprising a rectifier CR1 such as a Zener diode, a control winding C5 and a potentiometer connected across the capacitor C7, so that when the breakdown voltage of CR1 is exceeded the transductor impedance increases. The time constant of another control winding C4 together with a CR combination C13, R5 connected across capacitors C7 and shown in heavy lines delays the return of the circuit to the normal changing condition for a sufficient time to prevent after burning in the tube 3. The control winding C4 also limits the changing current to a desired rate by being supplied with a voltage from a resistor 16 through a rectifier CR27 and a resistor R17. The charging current is reduced by a switch 5<SP>11</SP> unshunting another resistor R15. If the voltage across capacitors C1 increases above a determined fraction of the bank voltage, a third control winding C3 will reduce the output voltage of the rectifiers CR9-14, a rectifier CR2 preventing a reversal of current in this winding, excessive voltages causing neon tubes V 3 -V 10  to flash over, rapidly reducing the voltage.

Title: Charged-particle-beam focussing and deflecting system
IPC: H01J29/58
Filed: 1970-06-12
Abstract: 1318933 Cathode-ray tubes RIKAGAKU KENKYUSHO 12 June 1970 [12 June 1969] 28693/70 Heading H1D A system for focusing and deflecting charged particles in which the beam, e.g. as emitted by an electron gun EG, is deflected towards a target screen SC by a deflecting system DPA, comprises a plurality of electrostatic or electromagnet lenses LMP adjacent the screen, each of which focuses the electron beam on to the screen when it is incident upon that lens. In one embodiment (Fig. 10) in which LB, LCL and LMP represent lenses of electrostatic or electromagnet origin, the beam is deflected by a directional deflection system LPA, focused by a focusing electrode LB and is then deflected by a positional deflecting system DPM through a collimator LCL on to one of the lenses LMP of short focal length. The angle of incidence on the lenses LMP is determined by the deflection by the directional UPA system while the position of incidence on LMPo or LMP as shown is determined by the positional - P - deflection. The deflection accuracy of the positioning DPM system need not be critical as the beam has only to impinge on a desired lens LMP. Additionally a positioning error of the beam on the screen due to an angular error in the directional LPA system is small since the error is proportional to the focal length f n  of the LMP lens which is short.  In the cathode-ray tube shown in Fig. 14 the directional and positional deflections are obtained respectively by LPA and LPMB coils and the focusing (cf. LB in Fig. 10) is obtained by the field of these coils. In front of the fluorescent screen SC are fine mesh electrodes FNS and BMS (e.g. 0À1 mm. pitch), the latter being connected to a cylindrical electrode RF the length of which is preferably 0À5 to 1À0 times its radius and which in combination with the coated anode AQ forms the collimator LCL. The short focusing lenses LMP may be produced by a 32 x 32 matrix of 1À5 mm. holes at 2 mm. intervals in a metallic plate at a voltage of about 0À4 to 0À5 times the voltage on the mesh electrodes FMS and BMS. The beam focusing arrangement as stated may be used in T.V. cathode-ray tubes, T.V. image pick-up tubes, electron beam memories, electron beam working apparatus, electron beam scanning microscopes and in positive ion focusing.

Title: Improvements in rotary cup valve
IPC: F16K27/04
Filed: 1921-10-29
Abstract: 180,624. Wilson, W. G. May 23, 1921, [Convention date]. Rotary disc valves; spindles; material, special. - A cup - shaped valve member having a non-circular closure face co-operates with a seating having a similar shape, the valve being opened by a rotary sliding movement. The valve-seat member 15, Fig. 1. is made fluid-tight by a gasket 18, and is oval or oblong at its upper portion 20 which co-operates with the closure member 21. The lower face of the closure member is of the same shape as the seating and is hollowed out to form a recess 22, as that when rotated through 90‹, Fig. 2, fluid may escape through the uncovered portions 44 of the seating, and also through the recess 22 into the central portion of the seating. A large valve opening is thus obtained. A depression 23 in the top of the member 15 receives the lower end 24 of a hollow spring- pressed plunger 25 in the lower end of the operating-spindle 27. This spindle is provided with lateral projections 33 which are adapted to rotate the member 15 through a pair of lugs 34 at each end. The two parts are secured together by pins 36. The spindle carries a handle 38. which may be provided with a projection engaging with stops 42 to limit the movement. Rotation of the seat member 15 may be prevented by lugs 4b, 47. In a modification, the plunger 25 and spring 32 are removed from contact with the fluid (snch as acid) passing through the valve, and placed outside the casing so as to press against the upper end of the spindle. In another modification, Fig. 8, the plunger 25b is pressed on the valve by means of a lever 58 pivoted at 56 to a horizontal spindle which passes outside the apparatus and carries another lever 61 under the control of a helical spring 32<b>. The apparatus may also be modified by the omission of the seat member 15, the seat being formed on the valve body itself. The valve member and other parts may be of glass.

Abstract: 1,235,707. Stabilized optical systems. OPTICAL RESEARCH & DEVELOPMENT CORP. June 17, 1968 [July 10, 1967], No.28800/68. Heading G2J. Optical stabilization apparatus comprises a light tight housing 11, a reflectively folding inverting telescope 12 directing light therein and having magnification of approximately two, the telescope 12 including an odd number of reflecting surfaces to retrodirect light in a substantially parallel bundle of rays on to a reflecting element 31 with an odd number of reflecting surfaces and inertially stabilized about two mutually perpendicular axes in such a manner as to reflect the parallel light in a bundle stabilized with respect to the housing 11, and a lens system 41 with at least one lens located in the path of the stabilized light. When the housing 11 is tipped slightly through an angle # the inverting afocal telescope 12 and triple reflecting element 14 made of glass or plastics reflects incoming light towards the object being viewed but deflected at an angle #. It is then reflected by the triple reflecting stabilized element 31 at an angle # which matches the deflection of the case to the image plane 42 in the same relationship as it does in the unrotated Fig. 1 (not shown). Element 31 is stabilized by means of a gyroscope 33 and precessor 34 with a flat spot in the curve of performance to allow a range in which it is ineffective. Therefore the gyroscope is effective for a small predetermined angular range but the precessor comes into operation for larger movements to allow panning. As an alternative to the triple reflecting element three mirrors fixed relative to each other could be used Fig. 3 (not shown). In an alternative embodiment light is collected and reflected by a concave mirror (54), Fig. 4 (not shown) at an angle to the original line of sight. The invention may be used for telescopes, binoculars or cine cameras.
