Title: Constant-frequency electric oscillation generators
IPC: H03B5/10
Filed: 1932-06-02
Abstract: 402,451. Valve generating circuits. STANDARD TELEPHONES & CABLES, Ltd., Connaught House, Aldwych, London.- (Assignees of Materiel Telephonique Soc. Anon. ; 46, Quai de Boulogne, Boulogne-sur-Seine, France.) June 2,1932,No. 15637. Convention date, Oct. 10, 1931. [Class 40 (v).] The frequency of an oscillation generator is stabilized by arranging a parallel resonant circuit &c. in series with a static negative impedance p and by making the resistances of the two branches equal. Fig. 5 shows an arrangement in which the two branches are made equal by added resistance, which may take the form of a non-inductive coil. Alternatively the inductance L may be divided to make the two paths equal the two parts being uncoupled. In a modification (Fig. 7 not shown) a stabilizing reactance is inserted in series with the negative resistance having a value equal to the product of the inductance of the tuned circuit and R1-R2/R1+R2 where R1 and R2 are respectively the resistances of the two branches of the tuned circuit. Fig. 8 shows a generalised circuit of a Hartley or Colpitts oscillator which may be stabilized either by connecting a reactance x5 between the valve anode and the oscillator circuit x1 x2, x3, xm or a reactance x4 between the valve grid and the oscillatory circuit. The Specification gives formulae for determining x4 or x5 from the circuit impedances.

Convention date, July 8, 1929. Void [Published under Sect, 91 of the Acts]. [Class 87 (ii).] Condenser tubes for retorts are made by placing extruded plastic material in a thin metal mould which is supported by a thick metal shell during the operation of pressing and moulding by a horizontal plunger machine. The mould shown in Fig. 1, having handles 4 on a central collar, and a lug 13, is placed in the three-part shell 17, Figs. 11 and 14, and locked therein by U-bolts 20, 21. A ram 7 with a forwardly-extending cylindrical portion, which extends completely through the mould and closes the outer end prior to the actual pressing operation, is controlled by three hydraulic cylinders, a central one 41 for advancing it and two smaller side ones 30 for retracting it. All the cylinders move in guides in the framing over fixed rams. Fig. 12 shows the valve gear for working at high pressure on the forward stroke and at lower pressure during the retraction. The automatic valve 35 is lifted by the low-pressure water in the pipe 37 during the return stroke and the water is delivered through the distributing pipe 40 to the cylinders. On opening the high-pressure valve 34 by hand, the high-pressure water closes the valve 35 and passes to the distributing pipes. The end of the moulded article may be treated further in the machine shown in Fig. 6 where it is squeezed between side dies 47 mounted on the ends of pivoted levers 48 and forced together against the action of the counterweights 52 by a cord 50 passing round pulleys 51 and actuated by the treadle 44.
