Abstract: 1,184,509. Seed sowing machines; fertilizer distributers. NODET-GOUGIS S.A. 19 Nov., 1968 [27 Dec., 1967], No. 54796/68. Heading A1D. An agricultural implement which distributes measured quantities of seeds or fertilizer comprises a number of blades 9, each of which is fed by an individual rotary distributer wheel 11 in turn fed by an individual container 10 open to the atmosphere at 16. One end of a pipe 27 runs into container 10 to a predetermined depth and the other end is bent at 28 and passes downwardly into a hopper 4 which is common to all the blades 9 and which can be tightly closed by a lid 5, a blower 23 for transporting the seeds or fertilizer being connected to the base of hopper 4. Wheel 11 is driven from ground contacting wheels 2. In operation air from blower 23 carries seeds into container 10 until the end of pipe 27 is partially obstructed. This slows down the speed of air in the portion of pipe upstream from summit 28 so that no more seeds pass through the summit until the end of pipe 27 in container 10 is freed.

Fuel is supplied as reductant via conduit 16 and air as oxidant via conduit 17 and the sensors, which may be thermocouples to product electric signals or may be such as to produce mechanical or fluid pressure signals, are connected to emplifier 24, which gives an output used to control the air and fuel supplied to an engine by a carburettor or fuel injection system to .produce exhaust gases of a predetermined constitution. With an injection system, Fig. 2 (not shown), a control mechanism (26) controls the air-fuel ratio in response to engine speed and manifold depression or throttle opening as well as in response to the output of the amplifier 24. The thermocouples may be replaced by thermistors in a balanced bridge network. The exhaust gases fed to inlet 11 may be a small proportion of the engine exhaust gas. The catalyst is plastisized titanium mesh.

Title: Universal frequency synthesizer

Filed: 1966-12-08
Abstract: 1,122,299. Automatic frequency control systems. C.I.T.- COMPAGNIE INDUSTRIELLE DES TELECOMMUNICATIONS. 8 Dec., 1966 [8 Dec., 1965], No. 55006/66. Heading H3A. A variable frequency oscillator 14 is locked to the frequency of a selected harmonic of a reference oscillator 11 which feeds an harmonic generator 12 and a high-pass filter 13, the two signals being fed to a mixer 15 feeding a phase discriminator 18 through a narrow band filter 17, the other input to the phase discriminator being one of the harmonics of the reference oscillator below the pass band of filter 13 and being supplied through a second narrow band filter 16 so that phase comparison is always at the same frequency whatever the output frequency, The output frequency is selected by inserting a corresponding number in a register 29 which sets a counter 23. Initially the frequency of the oscillator 14 is swept by a generator 19 until it reaches the frequency F B  of a second reference oscillator 26 when a mixer 21 produces an output which changes over a bistable circuit 28 energizing a relay 22. Thereafter each time the frequency of oscillator 14 passes through an harmonic of oscillator 11, an output from mixer 15 steps down the counter 23 by 1. When the counter is stepped down to a count of 1 it produces an output on line 30 which energizes relay 20, thereby putting the oscillator 14 under control of the phase discriminator 18. The output from the phase discriminator on line 31 also energizes relay 24; if synchronism is lost and this relay is deenergized, the supply source 25 and differentiating circuit 27 generate a pulse which restores the bi-stable circuit 28 and re-sets the counter 23 to the count stored in register 29 so that the frequency-finding operation is started again.
Patent GB-551013-A (GB)
Abstract: 551,013. Decarbonizing alloy steels ; pulverizing. BULL, G. H., and ALLSOP, H. Aug. 2, 1941, No. 9868. [Classes 59 and 72] In the decarbonizing of alloy steels containing 10 per cent. or more of chromium, the carbides or a substantial proportion of them are diffused to the boundaries of the individual crystals and precipitated there, preferably by heating to 600-800‹ C. for a sufficient time, the crystals coated with carbide then being separated from each other, e.g. by treatment with a corrosive re-agent such as an acid solution of a copper salt, and the separated crystals decarburized preferably by being brought into ultimate contact with cracked ammonia at a temperature of 600-1000‹ C. If the chromium is the sole alloying element in the steel, the separation of the crystals may be expedited by electrolytic action but if the steel contains sufficient nickel to make it austenitic, the crystals are separated mechanically. During de-carburization the crystals may also be agitated mechanically. In an example austenitic stainless steel scrap is heated to 1000-1150‹ C., cooled rapidly, reheated to 650-700‹ C., treated with an acid solution of copper sulphate and the powdered product exposed to a current of cracked ammonia at 600-1000‹ C. and preferably 650-800‹ C.

[Also in Division H1] A light emitting GaP diode has a graded junction near which the impurity concentration gradient is 1 x 10<SP>21</SP> to 2 x 10<SP>22</SP>  cm .-<SP>4</SP>. In an embodiment an N-type GaP substrate doped with oxygen and tellurium to a concentration of 5 Î 10<SP>16</SP> to 2 Î 10<SP>18</SP> cm.<SP>-13</SP> is ground and etched and sealed in an evacuated tube together with a source material comprising zinc or an alloy of GaP and zinc. The substrate is heated to a temperature of 850‹ to 950‹ C. and the source material is heated to a temperature of 650‹ to 750‹ C. to diffuse zinc into the surface of the substrate. The temperature of the substrate is then reduced to 750‹ to 850‹ C. and that of the source material to below 450‹ C. to anneal the substrate, the source material having little effect during this step. The diffused layer is lapped off one side of the substrate which is then scribed and broken to produce a plurality of diodes. The diode may be mounted in a housing having a lens in the cover, Fig. 2 (not shown). The starting substrate may also be doped with oxygen and selenium or oxygen and sulphur and the acceptor diffused into the surface may also be cadmium or magnesium. The diffusion and annealing steps may be performed in separate evacuated tubes. The diode may have a PIN configuration, the impurity concentration gradients in the P- and N-type regions on either side of the I-type region being within the specified range.

Abstract: 1367585 Digital transmission; FSK detectors NATIONAL CASH REGISTER CO 19 Dec 1972 [27 Dec 1971] 58484/72 Heading H4P An F.S.K. detector, Fig. 1, uses three phaselock loops 21, 22, 31 to generate a signal h indicating presence or absence of a carrier at the input a from the transmission line. The loop 31 senses the initial digit of a message which is a mark (1200 Hz) and sets a bi-stable 26. The bi-stable is maintained set by a signal from 25 as long as coherent energy in the line is sensed by loops 21, 22 indicating continued presence of a carrier. The loop 21 senses space frequency (2200 Hz), or a middle frequency (1700 Hz) which is shown to be present if the message continues even if the space frequency itself should fail to be sensed. The loop 22 senses mark frequency, or again the middle frequency, and if any of these three frequencies is present, a summer, filter and rectifier 24 produces the requisite D.C. level at the output of 25 to maintain the bi-stable 26 set. A decoded binary output is obtained at g from the input a by generating at 13 a square wave c whose frequency adopts one of the two (mark or space) frequencies (waveforms, Fig. 5, not shown), and then producing by means of differentiator 14 and monostable 15 corresponding trains of equal length pulses e at these frequencies. A filter 16 and threshold circuit 17 integrate the pulse trains, and shape the result to produce the binary output g.
