Title: Improvements in coupling devices for high-frequency electric circuits
IPC: H03H7/01
Filed: 1938-05-16
Abstract: 515,305. Impedance networks. JOHNSON LABORATORIES, Inc. May 16, 1938, No. 14573. Convention date, June 3, 1937. [Classes 40 (iii) and 40 (v)] [Also in Group XXXV] In an intermediate-frequency or like amplifier, the selectivities (as determined by the ratio of inductance to resistance) of two tuned circuits, and the coupling between them, remain constant as the tuning is adjusted by movement of iron cores: The inductance in each circuit comprises a part 4 with fixed coil 6, and a part 4a with movable core 7. The top core 7, Fig. 2, is adjusted by turning the set screw 18. For adjustment of the relative positions of the bottom core 7, and its coil 4a, the insulating tube 5, which carries the cores and coils, is raised by turning a nut 9, the bottom core 7 being held meanwhile by a screw 21. The parts can be so designed that the adjustment of the air gaps between cores 6 and 7 prevents variation of the ratio of inductance to resistance as the inductance is varied. In order that the coefficient of coupling may remain constant, the inductances may be so designed that the mutual inductance varies in proportion to the self inductances ; alternatively, variation in.inductive coupling may be neutralized by variation in capacitive coupling, account being taken of the condensers 8, 20 and of the capacity inherent in the valves, leads and coils. The coupling is preferably critical. Specification 515,194 is referred to.

Abstract: 595,805. Radio receiving systems. ELECTRICAL COMPONENTS, Ltd., and SUMMER, W. June 15, 1945, No. 15206. [Class 40 (v)] A trigger circuit responsive to a supersonic signalling tone is utilized for the remote operate of a switch in a broadcast receiver which is arranged to be automatically energized for preselected programmes. Audio signals from the detector output pass to amplifying stages over the circuit LCI. A supersonic tone transmitted between programme items is selected by the circuits LC2, 3'for application to a cold-cathode discharge tube CCT, which on firing energizes the stepping-magnet DM of a uniselector U. The uniselector wiper is thus advanced one step after each item, the relay A being energized to close the heater circuit of the audio amplifier in those positions in which plugs P have been previously inserted between the contacts S. The relays DM, A may be energized from D.C. or A.C. supply, shunt rectifiers MR1, 2 respectively being provided in the second case. The uniselector wiper may be re-set manually at the end of transmission, or automatically by transmission of the requisite number of impulses to complete one rotation. The instantaneous position of the uniselector may be indicated by means of a numbered disc D attached to the rotor. A bank of key switches (Fig. 2, not shown) may be used instead of the plug-and-socket arrangement P, S, and the programme capacity increased by employing a uniselector with two banks of contacts and with wipers in 180 degrees relationship. Means may be provided for recording desired items (Fig. 4, not shown), and the arrangement may be used for receiving programmes transmitted over the supply mains (Fig. 5, not shown).

Abstract: 720,151. Capacitance measurement; detecting changes in the proximity or nature of surrounding objects. FIELDEN (ELECTRONICS), Ltd. Sept. 17,1953 [June 18, 1952], No. 15320/52. Class 37. The impedance to be measured causes a difference voltage to appear across two rectifier circuits whereupon a motor responsively to this voltage drives a variable impedance in one of the rectifier circuits until the difference voltage is zero. The extent to which the variable impedance is adjusted is a measure of the unknown impedance. The rectifier circuits are fed with low-frequency (e.g. mains) modulated oscillations. The invention is described with reference to capacitance measurement. In the embodiment shown pick-up coils L2, L3 receive from a Hartley oscillator A radiofrequency oscillations modulated at mains or supply frequency and L2 is connected to a capacity electrode by a screened lead B. The coils L2, L3 respectively feed series-connected junction-earthed load resistors R1, R1A through rectifiers X1-X3 and X4-X6 preceded by phase-adjusting combinations L4, C5 and L5, C6 and variable capacitors CV1 and CV2, CV3. The R.F. carrier is filtered out by C1, C2 and normally equal and opposite voltages demodulated at supply frequency appear across R1, R1A. The capacity of the electrode varies with changes in the proximity or the nature of the surrounding objects and CV1 is scaled in appropriate units. To condition the apparatus for use, CV1 is set to maximum capacity with the test electrode at minimum capacity and CV2, CV3 giving coarse and fine control respectively are adjusted until zero voltage exists across the outers of R1, R1A. If the electrode capacity increases the R1 voltage exceeds that of R1A and the difference via transformer/amplifier/transformer T1/D/T2 operates reversible motor M and the latter adjusts CV1 to zeroize the difference voltage. The motor M is damped by D.C. drawn from rectifier E. The apparatus may be used for measuring the capacity of a test capacitor connected across CV1.

Title: Improvements in or relating to fountain pen fillers or ink bottles
IPC: B43K11/00
Filed: 1926-06-21
Abstract: 264,729. Kovacs, T. June 21, 1926. Fountain-pen fillers.-For filling nib-retracting fountain pens, a bottle U is provided having a short narrow neck V through which no ink will flow when the bottle is inverted except under the influence of capillary action set up in the space between the nib S and the inside surface of the bottle when the bottle neck is inserted in the mouth of the pen barrel Q, and the simultaneous entry of air. When the level of ink in the barrel Q reaches the lower end of the neck V, flow of ink stops owing to the cutting-off of the air-supply, and no ink will flow out of the bottle U when it is removed from the pen barrel because of the interruption of the capillary action set up by the nib S. An ordinary ink bottle may be adapted for filling nib-retracting reservoir pens by the employment of a hollow stopper similar in construction to the neck of the filling-bottle U.
