Abstract: 788,610. Valves. AKTIEBOLAGET SEPARATOR. April 18, 1955 [June 30, 1954], No. 11085/55. Class 135. In a rotary spherical plug valve, the axis of the valve spindle 10 coincides with a diameter of the plug and the latter carries one or more grooves 9 extending part-way around its surface and co-operating with an annular seat 8. The cross-sectional area of a recess varies along its length so that the passage provided between the inlet and outlet 3, 4 of the valve varies according to the position to which the plug is turned. There will be one position of the plug in which the flow of fluid is entirely cut off. The recess may be so shaped that the flow increases linearly in correspondence with the amount the operating handle 2 is turned. The recess may vary in depth along its length, and it may be provided with rounded edges.

Filed: 1956-04-24
Abstract: 832,551. Packaging. WALLACE & CO. Ltd., H. W., and MORE, A. R. April 16, 1957. [April 24, 1956], No. 11135/57 Divided out of 12479/56. Class 94(1). A conveyer 2 receives articles 1 and transfers them to a plate 9 until the leading article contacts a switch 10, 11 thereby stopping the conveyer, by disengaging a dog clutch from motor 3 and engaging it with stationary dog 5, and causing pneumatic thrustors 16, 17, 23 to move a pair of lifting bars 12, 13 cyclically outwardly, downwardly, inwardly and then upwardly so that they lift the row of articles to a position above plate 9. The conveyer is then restarted to feed a second row of articles beneath the first. When switch 10, 11 is again actuated the bars 12, 13 execute a further cycle thereby raising a two tiered row into a #-shaped member 30 where one of the upper articles engages a switch 27 thereby causing a pneumatic thrustor 29 and box 30 to move the articles on to a plate 32. On the completion of this movement a switch 34 is actuated thereby causing a thrustor 38 to move a plate 39 across plate 32 by a distance corresponding with the thickness of a row of articles whereupon a cam 41 contacts switch 42 and returns plate 39 and member 30 to their former positions. The machine continues to feed two tiered rows of articles to plate 32, and during this operation of the machine an open top box is placed on the hinged platform 43, a switch 44 is manually operated and a pneumatic thrustor 47 tips platform 43 and the box to a position in which its opening is aligned with the stack of articles on plate 32. When the last row arrives on this plate switch 36 is operated by an article, and if the box is in position so that switch 50 is also operated, the thrustor 38 executes a single long stroke to a position in which cam 41 engages switch 52 thereby pushing the stack from the plate 32 into the box.

Abstract: 583,822. Carbonization of coal. GIBBONS BROS., Ltd., and JONES, G. CELLAN-. June 14, 1945, No. 11526/44. [Class 55 (i)] In the carbonization of coal in a coke oven or like retort, "end gas," i.e. coal-gas stripped of its by-products, is introduced in controlled quantities at such a point in relation to the gas outlet that it does not pass through the fuel in the retort, but makes contact therewith. As shown the "end gas" is led from a source by a pipe d to a pipe e fitted with a valve f and connected to a tuyere g leading into the carbonising chamber a of the retort which has charging holes b, b, b, b formed in the crown h and a gas outlet c remote from the "end gas" inlet. The tuyere may be disposed in the end door of the retort or two series of tuyeres may be provided on each side of the door to allow the "end gas" to circulate along the passage between the wall and the charge. By using a series of tuyeres at different levels the height of entry of the "end gas" may be controlled. The "end gas" may be blended with other gases before introducing this mixture into the retort.

Abstract: 550,091. Wireless receiving apparatus. HAZELTINE CORPORATION. Sept. 13, 1941, No. 11753. Convention date, Oct. 8, 1940. [Classes 40 (iii) and 40 (v)] A receiver is tunable to a number of different intermediate frequencies by means of a selector network which comprises a pair of input terminals and a pair of output terminals, a plurality of transformers coupled between the input and output terminals the respective primary and secondary windings of which are connected permanently in series, each of the transformers being tuned to a different passband, and a single switch for short circuiting all but a selected one of said transformers so as to suppress the transmission of all applied signals except that to which the selected transformer is tuned. In Fig. 1, the intermediate frequency amplifier 42 is coupled between the oscillatormodulator 13 and detector 15 by a pair of identical selector networks 21, 22. Network 21 comprises input and output terminals 23, 24 and 25, 26 between which are coupled a pair of transformers 27, 28, the primaries 29, 30 and the secondaries 31, 32 of which are permanently connected in series. Primary 29 with condenser 37 is arranged to be resonant at one intermediate frequency, a resistance 39 giving a desired bandpass characteristic, while primary 30 together with condensers 37 and 40 is resonant at a second intermediate frequency. Secondaries 31, 32 and condensers 38, 41 are resonant at the same two frequencies according to which of the secondaries is energized. Network 22 is similar and switches 33, 33<1> are provided for short-circuiting either of the transformers at will to select the appropriate intermediate frequency. The secondaries of the transformers may be short circuited instead of the primaries if desired. Switches 33, 331 are arranged for uni-control with the wave-band switches 19, 20 of the high-frequency stages. A modification is described (Fig. 2 not shown) in which there are provided three series-connected transformers and a switch which short-circuits all but one to select the appropriate one of three different intermediate frequencies.

Abstract: 971,315. Radio-frequency couplings; valve oscillator circuits. COMPAGNIE FRANCAISE THOMSON-HOUSTON. March 28, 1962 [March 28, 1961], No. 11872/62. Headings H3F and H4A. Relates to the circuit arrangements between a self-excited valve or transistor oscillator 16, 10 Fig. 1, and a load impedance 1, 2 having a widely-varying resistive component due to coupling with, for example, a workpiece in eddycurrent or dielectric heating apparatus. According to the invention reactances 6, 7 are of 'opposite sign, the primary circuit incorporating reactances 6, 7 and the secondary circuit incorporating a reactance 5 and impedance 1, 2 are over-coupled, reactance 5 is capacitative when impedance 1, 2 is inductive and vice-versa, and reactance 6 or 7 is adjustable to vary the tuned frequency of the circuit 6, 7 to encompass the tuned frequency of the secondary circuit. A predetermined power output can thereby be maintained; the adjustment of reactance 6 or 7 may be manual, or automatic by known means not described. The circuit operation is described in the Specification with particular reference to the effects of the over-coupling, Fig. 2 (not shown). In one embodiment, Fig. 3, the variable reactance is a ferrite-cored inductor 7a and the ferromagnetic workpiece is in the field of inductor 1a; operation is at audio or radio frequencies and the oscillations are maintained by coupling 10. In operation core 23 is first pushed in to give a low oscillation frequency, Fig. 2 (not shown), before applying anode voltage, the core is then pulled out, after applying anode voltage, until full output power is achieved. As the Curie point of the workpiece is reached the output load impedance falls and the core is pulled out further to maintain maximum output power. Similarly any load impedance changes due to additional charges of material can be compensated. The manual adjustment may be made in response to temperature readings. Graphs illustrating the performance of the embodiment are described, Fig. 4 (not shown); the oscillation frequency is stated to vary over a relatively narrow range. In the dielectric heating embodiment, Fig. 5, the additional secondary circuit reactance is inductor 5b and the variable primary circuit reactance is capacitor 7b, which is initially set to a relatively low capacitance value. To hold the oscillation frequency constant a variable inductor 5b and/or a variable capacitor 28 is added. In the third embodiment two frequencies of operation of eddy-current heating apparatus are provided, Fig. 6 (not shown).
