Title: Improvements relating to the hydroforming process
IPC: C10G59/02
Filed: 1958-06-06
Abstract: The reforming of gasoline and naphtha is effected in two stages, the first being at at least 450 DEG  C. in the presence of platinum on a normally acidic support rendered non-acidic by the addition of an alkali metal and the second being at at least 450 DEG  C. in the presence of platinum on an acidic support.  The first stage catalyst support may be alumina containing halogen if desired with 0.01-5% added alkali metal particularly sodium which may be added by impregnation with an aqueous solution, e.g., of a fatty acid or mineral acid salt, drying, and roasting at 200 DEG -600 DEG  C. Suitable reforming conditions are 450 DEG -550 DEG  C., 300-1,000 p.s.ig., 1-5 vol./vol/hr. and 1-15 mols. hydrogen per mol of hydrocarbon.  In the second stage the catalyst support may be silica and/or alumina together with fluorine and/or chlorine. Temperatures of 450 DEG -525 DEG  C. may be used, otherwise conditions are as in the first stage.  The two catalysts may be present in the same reactor or each stage may be carried out in one or more reactors with common or separate hydrogen recycle.  Using more than two reactors the first and alternate reactors may contain the first catalyst, the remaining reactors containing the second.

Title: Improved manufacture of phosphorous pentoxide and phosphoric acid
IPC: C01B25/20
Filed: 1931-06-23
Abstract: Phosphorus containing gases from furnaces in which phosphorus is volatilized are burned and the burned gases are brought into contact with refractory walls, at least a portion of these walls being cooled by the passage of water through closed passages contained therein, thereby causing the precipitation of fume and like solid impurities while the phosphorus <PICT:0367690/III/1> <PICT:0367690/III/2> pentoxide is carried off by the gases.  Phosphorus containing furnace gases pass through pipes 6, 7 and a dust collector 5 to burners 9 from which they proceed together with air to a combustion chamber 10. In refractory side walls 11 of the combustion chamber there are mounted vertical tubes 12 embedded in carborundum or like material 12a.

Title: Hybrid coupler circuits
IPC: H03H7/48
Filed: 1975-05-01
Abstract: 1493030 Hybrid couplers; line equalizers WESTERN ELECTRIC CO Inc 1 May 1975 [2May 1974] 18313/75 Heading H3U A hybrid coupler circuit having an overall division ratio between the signal outputs which varies with frequency comprises a tandem array of hybrid couplers of which at least one has a frequency conscious division ratio different from the overall ratio. The loss characteristic of a transmission line has a slope approaching infinity at low frequency which cannot easily be compensated in a repeater amplifier. The above coupler circuit can be designed to have finite gain at zero frequency to improve matching between the line and repeater and perform initial correction. As shown in Fig. 6, the basic coupler circuit consists of two pairs 11, 12 of hybrid transformers with turns ratios of #2 as indicated and connected together by "antimetric" circuits 13, 14. These circuits are such that their matrix transfer functions when reversed and the dual constructed revert to the original matrix. For the circuits to produce non-quadrature outputs the inductance and capacitance values are the same as shown. The coupler has input terminals a, b and outputs c, d for which the overall transfer functions are t and k respectively and may be in-phase or in anti-phase although the circuit is termed an "in-phase hybrid coupler". The theoretical circuit of Fig. 6 may be simplified in plural stages by combining the turns ratios of transformer pairs such as 60, 66 (Fig. 7, not shown) and reflecting the reactances of the capacitors and inductors in the networks 13, 14 to produce the circuit of Fig. 9. It is also possible to absorb partially or completely the inductance and capacitance into the design core and/or leakage inductance and spurious capacitance of the transformers, resulting in a circuit like Fig. 10. More than two couplers may be connected in tandem with direct and transposed connections to produce two outputs as in Fig. 12 (not shown) or to produce plural division ratios (Fig. 15, not shown).

Title: Improvements in processes and apparatus for the continuous casting of metals
IPC: B22D11/20
Filed: 1945-07-17
Abstract: 598,385. Continuous casting-machines. ROSSI, I. July 17, 1945, No. 18337. Convention date, July 10, 1944. [Class 83 (i)] In continuous casting with intermittent withdrawal of the solid metal from the mould 1, this is stationary and, when it is filled to a predetermined point, the solid metal 8 is fed a predetermined distance and then stopped until the mould refills. The mould 1 is arranged in a water jacket 3 and supplied at a constant rate with molten metal by a tube 7 from a heated container supplied with gas under pressure. The metal 8 is lowered by rolls 9 driven through worm gearing 12, 13 and variable-speed gearing 17 by an electric motor 18, Fig. 4. This is started and stopped by a starter 18<1> and a control device 30, Figs. 4 and 7. With this in the position shown and the motor 18 stationary, the rise of molten metal in the mould completes a circuit through the contact 66, starter 18<1> and a solenoid 64 which tips a lever 63 to close a mercury switch 62 and thus energize the solenoid 33 of the control device and cause the disc 40 to be clamped to and rotated by the sleeve 32 which carries the solenoid 33 and is driven by chain gearing 34 from one of the rolls 9. The disc 40 is mounted on a drum 41, which is rotatable on the same spindle 31 as the sleeve 32, has an arm 43 to engage a fixed stop 44 and a cord and weight 46 to return it to the position shown when released by the solenoid. A. switch 60 is mounted on a disc 54 fixed on a shaft 51 adjustable by means of a knob 53 in the device 30 to vary the arc travelled by the arm 43 before it engages and closes the switch 60. When this occurs, a circuit through the solenoid 65 reverses the lever 63 into the position shown, thus opening the switch 62 de-energizing the solenoid 33 and stopping the motor 18. The weight 46 then returns the drum 41 to the position shown and the device is ready to repeat the cycle of operations. The disc 54 is frictionally held from undesired rotation by a spring-pressed disc 56. The shaft 51 has a pointer 52 adapted to move over a scale 50 to show the distance the work is fed at each operation. When the operator wishes to cut off a length of the work, he closes a clamp 22, Fig. 2, to connect a counterbalanced frame 20 arranged to slide vertically on rods 21. While the frame is moving at the same speed as the work. 8 a driven saw 23 is moved horizontally to sever the work. The rate of feed of the rod 8 should be such that the time occupied by one feed is less than the time between two successive feeds.

Abstract: 889,964. Television. FERNSEH G.m.b.H. June 1, 1959 [May 31, 1958], No. 18578/59. Drawings to Specification. Class 40(3). In an arrangement for recording a television signal on a magnetic tape the signal is firstly employed to frequency modulate a carrier wave which is then inserted in frequency (i.e. the higher frequencies in the television signal are made to correspond to the lower frequencies in the frequency modulated carrier wave) and supplied to the recording device. One arrangement for producing the frequency immersion comprises the steps of amplitude modulating a carrier wave with the frequency modulated wave, separating out the lower side-band (in which the frequency components are reversed with respect to those in the upper side-band) and then reconverting the lower side-band to the frequency of the carrier which was initially frequency modulated by the television signal. In another arrangement, the frequency of the carrier which is amplitude modulated by the frequency modulated wave is selected to be such that the lower sideband (containing the "inverted" signal) is in the range which may be usefully recorded on the tape. Circuits for producing the signals for application to the recording device and which include the first mentioned arrangement for producing the "inverted" signal and for reproducing the original television signal from the signal derived from a tape recording, are described with reference to Figs. 4 and 5 (not shown).
