Abstract: 1,233,892. Electric fence pulse generators. D. A. NEWELL. 24 May, 1968 [21 March, 1967], No. 13064/67. Heading H3T. In an electric fence pulser of the type in which a capacitor C 1  is periodically discharged via a thyristor 18 and an output transformer, the discharge is more complete when the fence is open circuited or loaded so that the discharges are more widely spaced. As shown, on first switching on, capacitor C 2  charges rapidly to provide a gate enabling potential. C 1  charges more slowly until the anode breakdown voltage is reached and the thyristor conducts. The output circuit rings and rapidly cuts off the thyristor when the capacitor C 1  has only partly discharged. Pulses are thus produced which because C 1  has only partly to recharge, are closely spaced. If the fence is open-circuited, or short-circuited as by contact with an animal the ringing is reduced or prevented and C 1  discharges more fully, so that the pulses are more widely spaced. The increased recharging current causes a warning neon across resistor 14 to flash. The severity of the shock may be varied by ganged potentiometers 14, 14A and the gate potential may be supplied through a transformer, Fig. 2, not shown.

Abstract: 1,234,622. Microwave heating. VARIAN ASSOCIATES. 26 April, 1968 [28 April, 1967], No. 19992/68. Heading H5H. A microwave heating apparatus comprising a plurality of parallel,preferably open-ended,waveguides 11 coupled together by apertures 13 in the walls near the end of the waveguides to provide a serpentine path for microwave energy wherein all of the waveguides have aligned horizontal slots 12 in their side walls to receive a workpiece, is characterized by conductive members 24, 26 which are positioned between the respective coupling apertures 13 and the open ends 22, 23 of each waveguide 11 to provide a short-circuit path for the electric field component of the microwave energy and thereby minimize reflections at the coupling holes and prevent leakage from the ends if open. The microwave apparatus is made in two identical sections, e.g. an upper section comprising a set 34 of half waveguides and a lower section comprising a set 36 of half waveguides. As shown, the conductive member 24 comprises a pair of longitudinal extending parallel strips 37, 38 and the member 26 a similar pair of strips 39, 40. These strips are secured by nuts and bolts 64, 66 to bridge the side walls of the waveguides and extend the length of the apparatus. The position of the strips relative to the length of each waveguide is adjustable, the bolts 66 being adjustable in slots 113, 114. To allow for variations in dielectric strength of material as it is heated in passing from one end of the apparatus to the other, the pairs of strips 37, 38 and 39, 40 converge slightly. Alternatively, the waveguides could have individual short circuiting conductive members 24, 26. Each set 34, 36 of waveguide halves is mounted on two U- shaped channels 49, 57. Energy may be injected anywhere into the waveguide but as shown a magnetron 14 is coupled by means of an H-plane T-junction 18 to one end of the outer waveguide. A similar T-junction 18<SP>1</SP> terminated in a dissipative water load 21 is provided at the opposite end to prevent reflections. Plenums 29, 32 on opposite sides of the apparatus are provided so that drying air may be passed by means of a series of pumps 31 through the waveguides and out via exit ports 33. The apparatus is used to dry continuous flowing paper sheets.

Abstract: 1,250,155. Measuring impedance. NATIONAL RESEARCH DEVELOPMENT CORP. Nov. 6, 1968 [Nov. 15, 1967], No.51976/67. Heading G1U. To compare two series-connected impedances 2, 3 current is passed through them from a first source 1, and two comparison voltages derived from a second source 7 are then adjusted until they balance the voltages respectively developed across the two impedances. The comparison voltages may be derived either from portions of a potential divider 6, Fig. 2, connected across the second  source 7 and forming, with impedances 2, 3, a bridge network, or from two windings 69, 70, Fig. 5, of a transformer coupled to the source 7. In either case errors due to lead impedances are avoided by automatically adjusting the relative magnitudes of sources 1, 7 to maintain zero current in one of the leads connecting the comparison voltage sources to the impedances 2, 3. The current in the or each other such lead is then also reduced to zero by manual or automatic adjustment of tappings on the potential divider Fig. 2 or one of the windings Fig. 5. The impedances 2, 3 may be resistive, capacitive or inductive, and the current passed through them may be either A. C. or D. C. In the D. C. version of Fig. 5, Fig. 8 (not shown) by source 1 (and transformer 64) are replaced by a D. C. source, and A. C. -D. C. converters are interposed between windings 69, 70 and the impedances 2, 3. Adjustment of the relative magnitudes of sources 1, 7 is effected by deriving one source from the other through a device 8 which includes an attenuator automatically adjusted in response to a detector 9, Fig. 2, or 4a, Fig. 5. The attenuator Fig. 3 (not shown) may comprise separate "in-phase" and "quadrature" potential dividers each comprising a series connection of a fixed resistance and a controllable resistance, e.g. an f. e. t. or a resistor responsive to some physical parameter. Fig. 6 shows a modification of Fig. 5 in which the number of turns on winding 70 is selected by a series of decade switches. Even finer adjustment is achieved by sub-dividing the voltage across an auxiliary coil 87 to a resolution of 1 in 10<SP>3</SP> by means of a further tapped inductor 93 and 10:1  ratio transformers 88, 89. In a modification Fig. 7 (not shown) errors due to loading of winding 87 are reduced by placing this winding (as winding 102) on a second transformer supplied from an auxiliary source (8a) whose magnitude is automatically controlled to keep the voltages across regulating windings (100, 101) on each transformer equal. The winding 69 may be tapped for range changing.

Abstract: 1301546 Making foil leads GENERAL ELECTRIC CO 24 March 1970 [1 April 1969] 14306/70 Heading B3A [Also in Divisions C7 and H1] A metal foil strip 1 for making foil leads for lamps is treated prior to being severed into individual leads by notching the strip edges, applying an etch-resist mask 6 to the narrow strip between the notches and electrolytically etching the strip to taper the exposed edges. The process is performed continuously on tungsten or molybdenum foil fed from a reel 31 to a notching punch 33 and a coating device 34. A similar coating device may be provided under the foil. The mask 6 is of silicone rubber. The strip is etched in a bath 8 of 12% sodium hydroxide solution for 7 minutes with an etching current of 6 amps between copper bar electrodes 9, 10. The mask is scraped off by a knife 19 and the foil is then guided to an acid bath 23 to neutralize the electrolyte. The strip is sprayed with water from nozzles 21 and then fed to an alcohol bath 24 and air nozzles 48 to dry the strip. The tapered notched strip can then either be wound on a reel 49 for storage and later separation into leads or be severed to form the leads. The masked parts 16, Fig. 12, of the leads are thicker than the etched part so that molybdenum or tungsten wire leads 28, 29 can be welded thereto. The masked parts may be doubled prior to welding.
