IPC: H03F9/04
Filed: 1955-10-07
Abstract: 803,239. Automatic voltage control systems. STANDARD TELEPHONES & CABLES, Ltd. Oct. 7, 1955 [Oct. 11, 1954], No. 28621/55. Class 38 (4). [Also in Group XXXIX] In a voltage regulator using magnetic amplifiers in cascade the connection between the D.C. output of a first magnetic amplifier and a control winding of a second magnetic amplifier inchides a rectifier the voltage across which is used to energize a negative feedback winding on the first amplifier. As shown, the output of an auto-self-excited bridge rectifying amplifier L2 is applied to a bridge rectifier W5 which is said to prevent A.C. being fed back from the control winding of a second magnetic amplifier L1. Feedback winding 9 of the amplifier L2 is connected across the rectifier 8 in the bridge W5 and as rectifier 8 has high resistance for low forward current and a lowering resistance with increasing forward current the feedback is non-linear. The output of amplifier L1 is rectified at W1 and applied to a load R1, R2, a voltage tapped from R2 being compared with a constant voltage source CVS and the difference providing an input to amplifier L2. The source CVS may be a regulator as described in Specification 745,796. The voltage from resistor R2 is adjusted to equal that of CVS when the load is at a minimum and the voltage supplied by transformer T1 is at a maximum, for which same conditions the negative feedback is adjusted by means of resistor R3 to give minimum output from amplifier L2. Specification 803,241, [Group XXXIX], also is referred to.

Title: Process and apparatus for preparing gaseous reaction mixtures
IPC: C10G67/06
Filed: 1964-07-13
Abstract: A gaseous mixture of hydrocarbon and steam suitable for catalytic reforming is prepared from a liquid hydrocarbon e.g. a light sulphur-cotaining petroleum fraction by at least partially entraining the liquid hydrocarbon, at 150-400 DEG  C. and at about the pressure used in the subsequent catalytic reforming, in a carrier gas containing hydrogen sufficient to hydrogenate the sulphur content, and preferably also an inert diluent, passing the carrier gas and entrained bydrocarbon over a catalytic bed, absorbing the H2S produced, and adding superheated steam to form the required mixture. Sulphur-containing or non-sulphur-containing gaseous hydrocarbons may be introduced into the liquid hydrocarbon before entrainment, or into the mixture of water vapour and hydrocarbon vapours before conversion, respectively.  The liquid hydrocarbon feedstock may be heated, e.g. by combustion of the non-entrained liquid hydrocarbon. The carrier gas may be recycled reformer gas with a H2 content of e.g. 70%.  The desulphurizing catalyst may comprise molybdenum, copper and active zinc oxides; H2S may be absorbed in active zinc oxide.  Apparatus comprising a pressure vessel with entraining and discharge means, a desulphurizing catalyst and an H2S-absorbing catalyst is described and claimed; the pressure vessel may be a distillation column whose plates are replaced by rings of material catalytic towards the desulphurizing reaction.  In an example the sulphur content of a petroleum fraction having an end-point below 200 DEG  C. was reduced from 300 p.p.m. to <1 p.p.m.

Abstract: 418,865. Time-pieces. HARWOOD, J., 120, Pinner Road, Harrow, Middlesex. Oct. 23, 1933, No. 29295. [Class 139.] Winding-apparatus.-In a time-piece, which is self-wound by an oscillating weight, the weight oscillates in or parallel to a vertical plane through the axis of the indicating hands and is combined with a toothless winding mechanism. Rigid with the winding arbor A<1> of the mainspring A is a disc B, the edge of which coacts with two studs G, G<1> and a lever I on a trefoil plate E. Lever I is connected by link O to an arm 0 <1> rigid with the weight W which oscillates about pivot R against spring X. When the link O is raised, the nose of lever I binds on the edge of disc B and the latter is moved counter-clockwise, Fig. 2, with plate E to wind the mainspring. A similar trefoil plate D with pins F, F<1> and lever H prevents retrograde movement of disc B in a clockwise direction. V, V<1> are buffer springs. To prevent overwinding the link O may be made in two relatively sliding parts which are joined together by an S-spring slightly weaker than the fully wound mainspring. A mark on the weight may be visible through a hole in the dial to indicate whether the weight is oscillating freely. The movement of the timepiece, or the timepiece as a whole, may be mounted for oscillation so as to function as the winding weight.
