Title: Production of Synthesis Gas by Catalytic Cracking of Hydrocarbons with Steam
IPC: C01B3/38
Filed: 1967-11-04
Abstract: Synthesis gas containing mainly H 2 and CO, with some CH 4 and C0 2 , is made by a two-stage catalytic cracking with steam of a hydrocarbon feedstock. The first stage, which produces a CH 4 -rich gas, is carried out in an unheated reactor at 350 to 550 C., and the second at 400 to 900 C. in an externally heated tubular reactor. Both stages employ Ni and/or Co catalysts. The internal surface area of the Ni or Co in the first catalyst is more than 20 sq.m./gram, preferably 30 to 300 sq.m/ gram, and the carrier is a precipitated oxide and/or silicate of Mg, Ca, Ba, Zn, Al and/or Ti. The catalyst at the inlet to the second stage contains a hydraulic binder, e.g. calcium aluminate, and the catalyst at the outlet to that stage may be the same as the first-stage catalyst. Feedstocks having 2 to 30 C atoms per molecule may be cracked, especially those having a B.R. of 30 to 200 C. The reactants are preheated, and if methanol synthesis gas is required, C0 2 may be added to the steam. Gas from the first reactor may be heated by heat exchange with flue gases from the second reactor, and the throughput of the first reactor is at least 2 kg of hydrocarbon per litre of catalyst per hour.

Title: Synchronizing circuit for secam switch
IPC: H04N9/455
Filed: 1967-11-15
Abstract: The invention is concerned with the synchronization of the phase of operation of a linefrequency switch 9, Fig. 3, used in a receiver of the SECAM (Registered Trade Mark) colour television system in which two colour signals are transmitted line-sequentially by frequency modulation of a carrier wave whose resting frequency is changed from line to line between two values. In accordance with the invention bursts of carrier signal, curve b Fig. 1, at the resting frequencies which occur during the blanking interval are separated from the received signal, curve a, by a gate 3 and applied to a frequency dependent circuit 10 to derive a voltage, curve g, from which a sinusoidal voltage, curve c, of half line frequency is filtered by a circuit 11. This voltage is then employed to synchronize a multivibrator 8 which drives the switch 9. As illustrated, circuit 10 is a frequency discriminator and circuit 11 comprises an oscillator. In an alternative arrangement, Fig. 2 (not shown), circuit 10 is replaced by the combination of a resonant circuit tuned to one of the resting frequencies and an amplitude detector, whilst circuit 11 is replaced by a resonant circuit. Reference is also made to the use for the frequency dependent circuit of a quartz filter which selects from the frequency spectrum of the carrier bursts two oscillations differing from each other by half line frequency, the oscillations being mixed to obtain the difference frequency. The arrangement shown in Fig. 3 may be operated alternatively with signals of the PAL colour television system where the carrier bursts during the blanking intervals have the same frequency from line to line but are changed in phase between two values differing by 90 degrees. Switch 12 is operated to the alternative position and connects the output of an oscillator 14, which operates at carrier frequency, to circuit 10, whereby the circuit functions as a phase discriminator Oscillator 14 is synchronized by the bursts of carrier signal by means of a variable reactance circuit 16 controlled by a voltage obtained from the output of circuit 10 via a CR network 15 having a time constant very much greater than the period of a line.

Title: Data storage circuits
IPC: G11C11/417
Filed: 1968-05-21
Abstract: In a storage circuit having a bi-stable circuit including two cross-coupled insulated gate field effect transistors Q1, Q2, the load of each transistor includes an insulated gate field effect transistor Q3, Q4 and the gate of each transistor Q1, Q2 iS connected to a semi-conductor switching device Q5, Q6, whereby when both the load transistors Q3, Q4 and the switching devices Q5, Q6 are off the gates of the transistors Q1, Q2 are effectively isolated. The power dissipated in the bi-stable storage circuit Q1,Q2 iS reduced by pulse operation of transistors Q3, Q4. The state of the transistors Q1, Q2 is maintained due to the voltage stored across the circuit capacitances C1 C2. If transistors Q1, Q3 and Q4 are ON and transistors Q3 and Q4 turn OFF then transistor Q1 also turns OFF, but on Q3 and Q4 turning ON again the voltage stored across C2 turns ON Q1 so that the state of the circuit is maintained. In formation may be read out of the store by applying a negative word pulse at 16 which turns ON transistors Q5, Q6-and allows the output at A and B to be fed via 12, 14 to a differential amplifier, the resultant output of which indicates the state of the store. Information may be written in by applying a negative word pulse at 16 and a positive pulse at 12 or 14. The transistors Q1-Q6 may be MOS. In an alternative circuit (Fig. 5, not shown), the gates of transistors Q3 and Q4 may be controlled from separate associative search sources and their drains may be connected to an associative sense line so that the condition of store can be determined by signals applied to the gates of these transistors Q3, Q4. The storage circuits may be connected to form a memory array (Fig. 4, not shown). The write, read and power lines may be transmission lines coupled to the storage circuits by directional coupling techniques. Each row has a common word line and each column has a common sense amplifier connected to the inputs 12, 14. The memory can be powered row by row at different times.

Title: Unitary control device
IPC: G05D16/06
Filed: 1968-08-01
Abstract: A main valve 26, 28 controlling the flow of fuel between the inlet 22 and the outlet 24 of a burner control unit is activated by a diaphragm 27 exposed on one side to the inlet pressure and on the other to the pressure in an operating chamber 32 which communicates via a passage 84 with a chamber 81 containing a bleed valve 92 and communicating via unrestricted and restricted bleed lines 82 and 78, 80 with the inlet 22, the bleed valve 92 being operative to either close a bleed passage 86, 88 leading to the outlet 24 and thus close the main valve 26, 28 by equalizing the pressures in the inlet 22 and the operating chamber 32, or to close the unrestricted bleed line 82 and thus allow the operating chamber 32 via the passages 84, 86, 88 to open the main valve 26, 28. The outlet 24 is connected to a main burner 10 ignited by a pilot burner 12 fed with fuel from the inlet 22 via pilot passages 44, 47, 51, 52. The pilot passage 44 is a groove in a rotatable and depressable plug valve 38 which is apertured at 40 to allow the main fuel flow. An inlet valve 72 is mounted on a lever 70 which projects into the path of the plug valve 38 and which is engaged by the armature 67 of a magnetic holding device 66 actuated by a thermocouple 14 sensitive to the pilot burner 12. The bleed valve 92 is spring- urged to close the bleed passage 86, 88, and is engaged by the armature 92 of an electromagnet 90 activated by way of a thermostatic switch 16, the bleed flow being regulated by a regulator 87. In operation, the plug valve is rotated to bring the groove 44 into registry with the inlet 22 whilst taking the aperture 40 out of register. The plug valve is then depressed to open the inlet valve 72 by way of the lever 70, the lever 70 urging the armature 67 against the electromagnet of the holding device 66. Thus fuel flows to the pilot burner 12 where it is ignited to activate the thermocouple and hence the holding device, the inlet valve 72 being held open by a torsion spring 71. The plug valve 38 is rotated to allow fuel to flow to the main valve 26, 28, which, if the thermostat switch is open, opens to allow fuel to the main burner 10. When the thermostat switch closes, the armature 92 of the electromagnet 90 causes the bleed valve to close the unrestricted bleed passage 82 to close the main valve 26, 28. Other embodiments of bleed valve are described with reference to Figs. 4, 5 and 6, 7 (not shown).

Title: Method of making insulated gate field effect transistors using ion implantation
IPC: H01L29/08
Filed: 1968-08-16
Abstract: The channel 24 of an insulated gate field effect transistor is bounded by portions 25, 26 of the source and drain regions which have been formed by ion implantation through the insulating layer 12 using the gate, source and drain electrodes 17, 16, 19 respectively as a mask. The width of the channel 24 is thus substantially equal to that of the gate electrode 17. In the Si device shown there are two channels 24 on either side of a common source region 6, 26. The major portions 6, 7 of the source and drain regions respectively are diffused, although relatively high energy ion implantation through a metal mask may alternatively be used, the preferred dopant in each case being boron. The electrodes 16, 17, 19 may, at the implantation stage, comprise parts of an integral layer of aluminium, which is subsequently selectively removed to leave only the electrode portions. This layer may be earthed during ion bombardment. The device is annealed at 500 C. after implantation. The insulating layer 12 may be of silicon oxide or nitride, or of superposed layers of oxide and nitride, and a phosphorus glass layer may be provided between the layer 12 and the gate electrode 17. The device described may be included in an integrated circuit including bipolar transistors, diodes, resistors and other insulating gate field effect transistors, parts of which devices may also have been formed by ion implantation.

Title: Positioning arrangement
IPC: B23Q1/44
Filed: 1975-12-19
Abstract: A positioning arrangement for an element, such as an abutment of an industrial cutting machine, which is mounted on an elongated rail for movement longitudinally thereof, includes a toothed portion rigid with and extending longitudinally of the elongated rail, and an arresting member having serrations which are adapted to matingly engage with the toothed portion in a plurality of positions. The arresting member is mounted on the element for displacement toward and away from the toothed portion, and also for limited movement relative to the element longitudinally of the elongated rail. The arresting member has two opposite lateral surfaces which diverge toward the toothed portion, and a pair of wedge members is provided, each of the wedge members having a wedge surface adapted to contact the lateral surface of the arresting member, the wedge members being mounted on the element for independent displacement toward and away from the toothed portion. A spring urges the arresting member toward engagement with the toothed portion, and a pair of flanges extends into the path of movement of the wedge members away from the toothed portion, the force of engagement of the wedge members with the flanges overcoming the urging force of the spring and thus disengaging the arresting member from the toothed portion. When the element is to be arrested in any of an infinite number of positions along the elongated rail, the wedge members first disengage from the flanges of the arresting member so that the spring displaces the arresting member into one of a plurality of discrete positions relative to the toothed portion, and then the wedge surfaces of the wedge members individually engage the lateral surfaces of the arresting member, thus connecting the element to the arresting member and arresting the former in the selected position.
