Title: Improvements relating to valve oscillating or amplifying circuits
IPC: H03F3/52
Filed: 1945-09-21
Abstract: 598,640. Valve generating and amplifying circuits. STANDARD TELEPHONES & CABLES, Ltd. Sept. 21, 1945, No. 24509. Convention date, Oct. 28, 1944. [Class 40 (v)] An oscillating or amplifying circuit comprises a grounded grid electron discharge device, the grid having an annular terminal and being mounted the common conductor of a pair of coaxial resonators, the inner conof which are connected to the anode and cathode, and in which feedback is provided by means of a coaxial line with means for providing separate adjustment for the phase and amplitude of the feedback. The Figure shows an oscillator or amplifier comprising a grounded grid valve 2, with a tuned coaxial anode-grid resonator circuit 9 and a tuned coaxial cathodegrid resonator circuit 8. Energy is fed back from the anode grid circuit 9 to the cathode grid circuit 8 via transmission lines 15, 16 and 17. In each case, the two outer conductors and the two inner conductors are slidably connected in known manner so that the point from which output is taken may be adjusted. Probe 20, which may be capacitively coupled to inner conductor 11 of anode grid circuit 9, supplies energy to phase line 15 which is preferably a non-resonant line of length exceeding one wavelength and which may be terminated by an impedance matching resistance. Probe 24 supplies energy to amplitude line 16 which consists of a resonant line which is an odd number of quarter-wavelengths long. Probe 27 supplies energy to connecting line 17 which feeds energy via probe 29 to the cathode grid circuit. The phase of the energy fed back may be adjusted between 0 degree and 360 degrees by moving line 16 along phase line 15. Since a standing wave exists along line 16, the amplitude of the energy fed back may be adjusted by movement of line 17 and probe 27 along line 16. Line 15 and line 17 may be adjusted along resonators 9 and 8 respectively to provide maximum output. Anode grid circuit 9 and cathode-grid circuit 8 may be tuned by means of slidable plungers 13 and 12 respectively and amplitude line 16 may also be tuned by means of plunger 25. The energy fed back may be arranged to be in a positive direction in the case of an oscillator, and in a negative direction in the case of an amplifier. The input of the circuit when used as an amplifier may be applied to the cathode-grid circuit in any known manner.

Title: Improved apparatus for counting the axles of vehicles running on rails
IPC: B61L1/16
Filed: 1931-09-01
Abstract: 380,585. Counting- apparatus. VEREINIGTE EISENBAHN - SIGNALWERKE GES., Siemensstadt, Berlin. Sept. 1, 1931, No. 24581. Convention date, March 10. [Class 106 (i).] Vehicles passing along a rail track are counted by arranging that they shall close switches which cause the charging or discharging of a condenser through a counting mechanism. The closing of a switch A, Fig. 1, by a vehicle causes a condenser C to be charged through a counter Z, which is thereby actuated. The further movement of the vehicle closes the switch B to discharge the condenser through a resistance R1. In Fig. 2, the closure of a switch 1 charges the condenser C and the closure of a switch 2 maintains the charge through a high resistance R and so eliminates the effect of condenser losses. When a switch 3 is closed the condenser is discharged through the counter Z. If a vehicle operates switches 1 and 2, and its direction is then reversed, a switch 4, actuated by another axle of the vehicle, discharges the condenser and prevents the operation of the counting mechanism In a further modification, some of the contacts are duplicated and arranged in parallel to ensure the operation of the device by highspeed vehicles.

Alternatively, the cam track takes the form of a ring arranged eccentrically with respect to the chamber.
Patent GB-588377-A (GB)
Title: Improvements in and relating to the production of furan derivatives
Filed: 1944-12-11
Abstract: Furoates, substituted in the 2- or 5-position by halogen-substituted alkyl groups, are obtained by treating furoic acid esters of general formula <FORM:0588377/IV/1> wherein R represents a carboxylic ester group, with a hydrogenhalide and an aliphatic aldehyde in presence of a dehydrating agent selected from zinc chloride, phosphoric acid, concentrated hydrochloric acid and aluminium chloride.  The reaction is expressed in the general equation <FORM:0588377/IV/2> wherein R has the significance stated above; R1 represents H or alkyl, especially a saturated alkyl radical not exceeding five carbon atoms; and X represents halogen.  Additionally, when R1 represents H or a saturated alkyl radical not exceeding five carbon atoms, there are produced compounds of the types <FORM:0588377/IV/3> referred to as compounds of the types A and B.  Furan compounds suitable as starting-materials are methyl-, ethyl- and n-butyl furoates. Specified aldehydes are formaldehyde and acetaldehyde, also applicable in their monomeric or polymeric forms, e.g. paraformaldehyde or paracetaldehyde.  Gaseous hydrogen chloride is preferred as the hydrogen halide, and, where chlor-substituted alkyl groups are to be introduced, it may function both as a chlorinating and a dehydrating agent; otherwise, zinc chloride, phosphoric acid or aluminium chloride are preferable.  An inert organic solvent for one or more of the reactants and/or the products, e.g. a chlorinated hydrocarbon, may optionally be present.  The temperature-range preferred does not exceed 40 DEG  C., and more particularly, 30 DEG C., although temperatures up to 100 DEG  C. may be employed. Specified chloralkylated compounds prepared are methyl 5-chloroethyl-, ethyl 5-chloromethyl- and butyl 5-chloromethyl-2-furoates.  Methyl furoate, when treated with formaldehyde and hydrogen chloride at about 20 DEG  C. in presence of zinc chloride and of a solvent, e.g. methylene chloride, yields, in addition to the chlormethylated compound, the substance <FORM:0588377/IV/4> while, if the reaction is conducted at 70 DEG  C. in the absence of solvent, the secondary product is <FORM:0588377/IV/5> The compounds of types A and B are generally higher - boiling than the halogen - alkyl - substituted compounds and can be separated by fractional distillation after removing the latter.  In an example: methyl furoate, paraformaldehyde, zinc chloride and methylene chloride are stirred together at 30 DEG  C., in a stream of hydrogen chloride and the reaction-mixture is poured into water, methyl 5-chloromethyl-2-furoate being isolated from the non-aqueous layer.
