Abstract: 815,449. Electric tests. MINNEAPOLIS-HONEYWELL REGULATOR CO. Oct. 17, 1957, No. 32525/57. Class 37. In a system for determining liquid level of the type in which the liquid forms the dielectric between electrodes of a condenser, to prevent false indications caused by deposits on the electrode spacers, a conductor connected to a reference potential traverses that part of the surface of each spacer on which the deposits may appear. Fig. 1 shows cylindrical electrodes 10, 11 spaced by nylon bobbin 13. Around the waist of each bobbin is wound conductor 19 which passes through a hole in the bobbin and is supported by a diametral lead wire support 16 before being finally connected to a lead 15 which is connected to the reference potential. Fig. 5 shows a measuring circuit in which amplifier 27 receives signals in anti-phase from the measuring condenser 30 and a comparison condenser 28 respectively supplied from opposite halves of the centretapped secondary of transformer 20. Unbalance causes a motor to run to adjust potentiometer 26 which is calibrated in liquid level. Deposits on the electrode spacers act as a shunt .on condenser 30 and thus falsify the readings. The effect of the conductor of the present invention is shown by the dotted resistors 31, 32 one of which acts as a transformer shunt and the other as an amplifier shunt reducing sensitivity but leaving the reading unchanged.

Abstract: 619,156. Valve modulating circuits. COSSOR, Ltd., A. C., and MOSS, H. Nov. 8, 1946, No. 33314. [Class 40 (v)] In order to obtain 100 per cent modulation with low distortion, unidirectional radio frequency pulses are applied to the grid of an anode modulated valve; the resultant modulated pulses being applied to a resonant circuit from which amplitude-modulated oscillations are derived. The short grid-base valve V1 supplied from a high voltage anode potential source has a high resistor R3 in the cathode circuit byepassed at RF by a condenser C1, which, however, allows negative feed-back of audio -frequencies ; and the grid is connected to a potential divider R1, R2 in which R1>R2, so that the anode current is substantially proportional to the anode voltage. Negativegoing pulses at carrier frequency are applied to the grid by a tuned high-frequency transformer and a rectifier T. Audio-frequency modulation is applied in the anode circuit at K. A tuned circuit LF, C3 converts the amplitude-modulated pulses into amplitude-modulated oscillations.

[Also in Groups XXXVI and XL (b)] In a double-base diode comprising a semi-conductor member 4, Fig. 5, of which one base electrode 1 and a barrier layer electrode 3 may be connected in a heavycurrent load circuit, whilst the conducting state may be brought about by means of light which causes a carrier injection in the semi-conductor region between the electrodes 1, 3, the semi-conductor member is made of a material having a resistivity of more than 1000 ohm-cm. and is so constructed that the distance between electrodes 1, 3 does not substantially exceed twice the diffusion length of the charge carriers. As shown, the diode comprises a single-crystal main body 4<SP>1</SP>, Fig. 7, e.g. of silicon, gallium arsenide or aluminium antimonide. The main body may be slightly N-conducting with highly-doped N-conducting regions adjacent the gold-antimony base electrodes 1<SP>1</SP>, 2<SP>1</SP>. The annular barrier electrode 3<SP>1</SP> may be of a goldboron alloy. The body 41 is cemented by an insulating foil 5<SP>1</SP> to a metal body 6 of good thermal conductivity. The device may be employed in place of a photo-cell having a preamplifier, e.g. in dusk or dawn switches, machine-tool drives or light barriers. As shown in Fig. 5, the working electrodes 1, 3 are connected across an alternating current source 15, which also supplies, through phase-shifter 14, a motor 13 driving an apertured disc 12. The arrangement is such that light from source 11 impinges on the diode within the pass half-wave, of the alternating current. As shown in Fig. 6, the load circuit of a main diode 17 is locked by two relays 20, 24 to an auxiliary circuit comprising a second diode 21 and a voltage source 22 weaker than source 18, so that diode 17 is alternately ignited by successive light pulses from source 25 and quenched by the ignition of the auxiliary diode 21.

Fine-grained carbonaceous material, e.g. coal, coke, sawdust, coal slime, is gasified in two producers in series 1, 5, in the first of which whirling conditions are created and the reaction temperature exceeds the melting point of the ash constituents; the volume of the second producer is a multiple of that of the first and the concentration of particles in it is increased as by providing a column of filling bodies 6 surmounted by a fluidized bed 7. Gasifying agents comprising oxygen, air, &c. are introduced into producer 1 from the side as a cyclone 2 and fresh material into producer 5 at points 8 or 9, oxygen-containing gases entering at 10 and steam at 11, 12. Heavier particles are extracted through an outlet 14 and the lighter are separated from the gases in a cyclone 16 and returned with the heavier particles to producer 1. Molten clinker is drawn off through a drain 13. In addition to water vapour, carbon dioxide and hydrocarbons may be supplied to producer 5 which may contain catalysts, or to the gases coming from producer 1 to which fuel may also be added. The gas composition may also be regulated by employing two or more small producers in parallel. The fuel may be preheated in a feed cyclone in which preferably gaseous fuel is burnt. The larger producer may be arranged as in Specification 33431/48 (as open to inspection under Sect. 91) and coke employed as filling material. Specification 669,906 also is referred to.

Abstract: 466,578. Making and covering boxes. STOKES & SMITH CO. Dec. 3, 1935, No. 33493. Convention date, Oct. 10. [Class 18] In a machine for covering formed or stayed boxes, or for folding blanks into boxes and covering them, of the type in which the work is moved down between tool units S<1>, S<2>, S<3>, adjustable by screws 47 to and from the work B and having tools 51, 69, 78, 89, &c., acting on the several sides of the work, the form block MF, AF is kept stationary at the top of its stroke while the main cam 1 rotates more than 30‹, or the form block is given a slow downward motion for a corresponding time, to facilitate the introduction of the work, and permit of the cam 1 being rotated continuously. The former is in two parts, the part MF being connected by a rod 4, and plug 5 to a cylinder 6 carrying a rack 8 in gear with a wheel 9 operated by levers &c. 14, 17 from the groove 19 of cam 1. The other part AF of the former is connected by rods 20 with a rod 21 within the cylinder 6. A spring 24 and a collar 23 ensure that the two parts of the former work together except when the collar 23 rests on the top of another cylinder 27, carrying the strippers 36 and operated through a rack 28, wheel 29, and levers &c., from the groove 35 of cam 1. The various tools of each tool unit are operated through levers &c. 62, 74, 85, 95 from a cam 40 within the unit and driven from the cam 1 through gearing 50, 49, 45, 44. Two opposite tool units S1, S2 have rollers 51 for wiping up the side panels of the wrapper into engagement with the side panels of the box as the box first moves down, corner lap tools 69, marginal turn-in fingers 78, which fold over the portions M of the wrapper while the two parts of the former MF, AF are separated, and pressing tools 89. The other two tool units are not fitted with corner lap tools. but one carries an ejector 115. A spring- pressed sleeve 120 with a conical interior normally presses balls 117 into a groove 123 in the ejector rod 111 and locks the same in its retracted position. Between a collar 119 on the rod 111 and the end of a sleeve 112 surounding the rod is a spring 118. As the sleeve 112 is moved by the lever 101 and cam 104, the spring 118 is first compressed and when the sleeve 112 moves the sleeve 120 the rod 111 is freed and the ejector fires. Reference has been directed by the Comptroller to Specifications 19967/01 and 250,355, [both in Class 18].
