Title: Improvements in wireless receiving circuits
IPC: H03F3/48
Filed: 1923-05-23
Abstract: 217,409. Voigt, P. G. A. H. May 23, 1923. Thermionic amplifiers and detectors. - By means of a biasing battery the grid potential of a valve acting as a simultaneous high and low frequency amplifier is set at the lower bend of its characteristic curve, so that the low-frequency voltages fed back from a crystal detector to the grid of the valve are caused to remodulate the incoming carrier wave by an action similar to that which occurs at the transmitting station. Alternatively the grid potential may be set to a positive value, the re-modulation process then being effected by grid current damping. As shown in Fig. 3 the low-frequency feed-back is caused to vary the plate voltage applied to the first valve of a three-valve set. The amplified low-frequency variations from the detector valve D set up corresponding changes in the plate current of the third valve E. An increased plate current lessens the plate voltage on the first valve A, and so drops the operating point from its initially-set position near saturation The result is an increase in amplification which gives rise to a re-modulation or low-frequency reaction as before. A condenser G controls electrostatic reaction.

In one form Fig. 1, the pawl 12 is directly pivoted to the hand lever 5 and is disengaged from the rack 14, when the handles 4, 5 are opened, by the engagement of a projection 16 on the pawl with a tongue 15<a>. The jaw 8 is guided by grooves engaging ribs 9 on the side plates 1 of the tool and uncontrolled movement of this jaw is prevented by a flat spring 10, or by a spring pressed ball mounted in a hole in the jaw and bearing against one of the plates 1. A removable pin 18 is provided to prevent the jaw from falling out. The handles 4, 5 may be retained closed by turning a hook 19 into engagement with a notch 20. In a second form, Fig. 2, the pawl 12 is connected to the handle 5 by a link 28 and is moved parallel to itself by the engagement of inclined faces 21, 24 on the pawl with fixed inclined surfaces 24, 25. The handles are retained closed by a pin 29 which is slidden over the spring 17 to hold it inoperative. In both forms the fixed jaw is detachable and consists of aT-member 7, Fig. 2, the stem of which is secured between integral plate parts 7b, Fig. 1, of the tool body by bolts 7<a>.

[Class 40 (v)] A frequency modulator comprises two backcoupled valves operating with a common piezoelectric crystal and tank circuit, but with reactances of different sign in the respective feed-back circuits so that the valves tend to operate at different frequencies ; and the modulating voltage is applied differentially to control elements in the valves. As shown, the crystal X is connected between the anodes and the control grids of the valves V1, V2, the grid connection of one including a condenser C and of the other an inductance L. Resistances R1, R2 connect the respective grids to the earthed cathodes, and a common tank circuit Cl, L1 is connected between the anodes and HT+. Modulating voltage is applied through a transformer T in push-pull relation to the positive outer grids of the valves, so that the transmitted frequency varies continuously as each valve in turn predominates in its effect. The modulating voltage may be applied to the inner control grids, Fig. 3 (not shown). In a modification, the crystal X is connected between the cathodes and the junction of the condenser C and inductance L, which junction is connected to the anodes by a variable condenser, Fig. 2 (not shown).

Abstract: 417,620. Nozzle valves. MORRIS, J., MORRIS, JUN., J., and MORRIS & SONS, Ltd., J., Salford Fire Engine Works, Cross Lane, Salford, Lancashire. May 13, 1933, No. 13929. [Classes 69 (iii) and 135.] In a jet control and shut-off nozzle for use with branch pipes, hoses &c. particularly for fire-brigade &c. use, a stream-lined valve is concentric with its seating to provide an uninterrupted flow of fluid, relative motion between the valve and seat being produced by rotation of an external sleeve acting through a screw thread. Closure or adjustment of the jet does not alter the overall size of the nozzle. In one form, the double conical valve b is secured in a coupling union c by a spider c<2> and the seat a<1> is formed as a sleeve a slidable within the nozzle d. A short sleeve e is secured to the sleeve a by pins e<2> passing through slots d<1> in the nozzle and is provided with an outer square or other screw thread coacting with a rotatable sleeve nut f. The nut f rotates between a shoulder on the nozzle and a screwed ring g secured thereto by a set screw g<1>, and prevents access of grit &c. to the working parts. Access of water to the working parts is prevented by a screwed packing ring dx. In a modification the screw thread on the nut f and sleeve e is a two-start thread of considerable pitch so that the full range of adjustment is obtained with less than a complete revolution of the nut and a spring pin on the ring g co-operates with recesses in the upper edge of the nut to locate the nut definitely in different angular positions which are indicated by graduations on the nozzle. In a further modification, the valve seat A<1>, Fig. 23, is formed in the nozzle A and the valve b is attached by a spider to a sleeve B<1> connected by pins E<2> to the short screwed sleeve E which is movable axially by the outer rotary nut F. In each construction graduations may be provided to indicate the setting of the valve.

Abstract: 1386427 Counting apparatus WIRTH GALLO & CO 27 March 1972 [28 April 1971] 14177/72 Heading G4D [Also in Division G1] A weighing apparatus which calculates the price of a weighed article from a keyed-in price per unit weight and then totals a number of prices, allows unit weight to be set into the calculator whereby prices of items not needed to be weighed can be keyed-in and added to the total. In Fig. 2 the weight of an article determined by a measuring cell 1 generates two A.C. signals of different frequencies, F 1  which increases with weight and F 2  which decreases with weight. F 2  is passed to counter 5 which, after a predetermined count, signals control unit 8 which produces a stop signal for counters 13 and 11 to which F 1  has been applied. Counter 13 counts only during half the predetermined count of F 2 , and the result is doubled; if the weighing process has reached stability, the doubled count of 13 will equal that of counter 11. A price per unit weight is keyed-in from keyboard 18 to a multiplier 17 which calculates from the output of counter 11 the price of an article and supplies this via unit 13 (now used as an intermediate store) for addition to the total in 22. The total, weight, price and price per unit weight are printed out and displayed via lines 15 and 20. A key 6 when operated sets register 11 to unit rate, e.g. 1000 kg. enabling the keyboard 18 to key into multiplier 17 the price of an item which then multiplies it by the unit rate for addition to the total in 22 as before. An erase key 24 also sets register 11 to unit rate allowing a price, which had previously been added to the total in 22 in error, to be keyed-in from keyboard 18 into the multiplier 17, placed in register 13 and its complement formed in circuit 25 for addition to the total in 22, thereby subtracting the erroneous price from the total.
