Abstract: 1419419 Mixing fluids; precipitating-apparatus SOC MINERARIA E METALLURGICA DI PERTUSOLA 29 June 1973 [30 June 1972] 31239/73 Headings B1C and B1X [Also in Division C7] A zinc-plating solution containing metal impurities is purified by agitating the solution with Zn granules to remove the impurities as precipitates. The solution is pumped from reservoir 4 through pipe 6 to the lower chamber 1 of a cementation column having a rotary cage 14. The solution rises through chamber 1 and reacts with Zn granules fed through pipe 10, the impurities precipitating briefly on the granules before scaling off as the granules collide in the turbulent conditions caused by the rotating cage 14. The solution passes into the upper chamber 2 having a rotating cage 15 where the reaction continues before passing into a filter 20 and being recycled or returned to the plating bath. The feed of solution through pipe 6 is controlled by flowmeter 37 acting upon valve 7, and the supply of granules by manometer 29. Activators may be injected at 30, 31, 32, and the upper chamber 2 contains sampling outlets 33, 34.

Title: A method of making abrasive metal carbides and a furnace structure therefor
IPC: C01B31/30
Filed: 1936-11-16
Abstract: <PICT:0483248/III/1> In making carbides of boron, silicon, titanium, or tungsten by reacting a mixture of carbon and the appropriate oxide by means of an electric resistor 22 in the charge, the reaction takes place in a closed furnace casing 10 and a non-reactive atmosphere is maintained in the furnace throughout the reaction and also during the subsequent cooling of the charge.  The exterior of the furnace is cooled during the reaction to form an outer cold layer in the charge capable of condensing and holding volatile material from the central high temperature zone.  Carbon monoxide is formed during the reaction and furnishes the non-reactive atmosphere in the furnace, the excess gas escaping through outlets 34.  The latter are closed by graphite plugs 38 during the cooling stage to maintain the atmosphere in the furnace.  A perforated wall 54 forms a space above the charge for collecting the generated gases. Specification 415,392 is referred to.

[Also in Division A4] A maize harvester comprises a frame 10, a first gathering means 36 on the frame for gripping the standing crop, conveying it rearwardly a short distance and then releasing it, a second gathering means 60 to grab the standing crop after release by the first means and to convey it rearwardly, and cutting means 92 which severs the crop as it is grabbed by the second gathering means. The gathering means include two dividers 32, 34 V-shaped in both elevation and plan and spaced to produce a convergent entrance to a longitudinal crop-conveying channel 35. The first gathering means comprises toothed endless chains 38, 39 overlapping at a grip-point 49 and diverging at a releasepoint 50. The second means comprises a similar pair of chains 61, 62 travelling, within the channel 35, at a higher speed and overlapping at a grab-point 69.

Title: Improvements in and relating to machines for filling containers such as cans or bottles with liquid
Inventor: BREEBACK RUDOLPH HENRY
IPC: B67C3/06
Filed: 1960-09-12
Abstract: 921,684. Rotary filling machines for cans &c. CROWN CORK & SEAL CO. Inc. Sept. 12, 1960, No. 31399/60. Class 125(2). [Also in Group XXIX]. In a counterpressure filling machine, e.g. for carbonated liquids, the gas displaced from the container during the entry of liquid is vented to a second pressurised reservoir 30, 31, separate from the pressurised liquid reservoir 18 from the head space of which the counterpressure is obtained, a constant pressure differential being maintained between the reservoirs. The machine is a revolving table type with containers carried by revolving arms C into position beneath filling heads 114. Each filling head 114 is connected to the reservoir 18 by counterpressure and liquid supply pipes 120, 144 and to the reservoir 30 by vent pipe 164, which pipes are connected in correct sequence to the container C by a rotary valve 16 actuated through trip arms 44, 46, by stationary cams. Reservoir 30 is connected to reservoir 18 through a pressure control valve 248 which maintains a constant pressure differential therebetween, a check valve in valve 248 permitting gas to flow only from chamber 18 S to chamber 30. A pressure relief valve on reservoir 30 is also controlled by a diaphragm in the device 248 loaded by the pressure on the two reservoirs. The rotary valve 16 comprises a disc 41, Fig. 3, mounted on a fixed bolt 65 and actuated by the arms 44, 46, through a cap 42 keyed to the disc by a spigot 84, springs 94 holding the disc against its seat 60. Each filling head, Fig. 25, has a counterpressure supply passage leading to orifice 24, liquid passages 216 each connected to a plurality of nozzles 226, and a vent passage 210 leading from the orifice 204. Filling is terminated when a float valve 292 closes the orifice 204. The valve 292 comprises two plastic hemispherical sections 302, 304, Fig. 31, of different thickness so that the ball always floats with the thin section 302 uppermost and the seam 306 is prevented from engaging the seat. In a modification, Fig. 28, the counterpressure gas is supplied through passage 200<SP>1</SP> to a number of passages 272 situated between the nozzles 226. The vent passage 210<SP>1</SP> includes a spring-loaded valve 282 which is opened by a cam 284 during the first portion of the period in which the counterpressure is built up in the container C, whereby the air displaced from the container is vented to atmosphere. The valve 282 then closes so that during the filling step, the displaced counterpressure gas is vented to the chamber 30, Fig. 1, as previously described. Specification 522,229 and U.S.A. Specificacation 2,097,107 are referred to.

[Also in Group XL (c)] A variable impedance comprises a capacitor and a rectifier connected in series between two terminals, and a further rectifier and a source of variable bias voltage is connected across the first rectifier, the two rectifiers being in reversed parallel connection and the source of bias voltage is a capacitor shunted by a leakage resistance connected across both the rectifiers, the bias thus varying according to the current circulating in the impedance circuit. In Fig. 7, the arrangement is shown applied to the frequency modulation of an oscillator. A control voltage is applied at terminal T4 of valve V2 and the current in resistance R is thus varied, this resistance supplying the bias for a circuit (capacitors C1 and C2 and rectifiers D1 and D2) according to the invention. This circuit is linked with a resonant circuit LS in the output connection of an oscillator valve V1. In the receiving and transmitting set shown in Fig. 8, current from a microphone H with its associated valve V2 modulates the output from oscillator valve V1 through a variable impedance circuit C2 as in the previous construction. The receiver circuit comprises a local oscillator O, a mixer M, amplifier E, discriminator F, valve B and earphones G. Specification 667,065, [Group XL (c)], is referred to.

[Also in Division H4] In an arrangement for testing a P. A. L. colour television transit time demodulator [See Division H3-5] a cathode-ray display, Fig. 3, is produced in which the position of a minimum signal (f = fo) along the x axis indicates the delay value of a delay line which is to be connected in the demodulator circuit. The display is masked except over a narrow region about the x axis, Fig. 4, and is viewed by a photo-cell 53 which determines the position of the signal minimum and controls the wire guide 52 of a manufacturing machine whereby a delay line of the appropriate delay is produced. The delay line comprises a winding in the form of a solenoid. For short lengths of winding the delay is not directly proportional to the winding length. Compensation for this is effected by distorting the x deflection of the cathode-ray tube. When the delay line is connected in the demodulator circuit a final fine adjustment of the delay is made by a phasing control. The extent of this final adjustment is a measure of the accuracy of manufacture by the machine. Means are provided for feeding back a correcting effect to the machine determined by the extent of the final adjustment.
