Title: Improvements relating to the catalytic treatment of hydrocarbon feedstocks
IPC: B61F15/10
Filed: 1960-10-28
Abstract: In the catalytic treatment of hydrocarbon feedstocks employing a fixed bed of catalyst, the catalyst consists of a layer of catalyst material supported on a matrix, the material of which is substantially devoid of pores with diameters below 1 micron, the ratio of the weight of catalyst material to weight of total catalyst being less than 0.5, and also less than <FORM:0956285/C3/1> where #q is the ratio of the total volume of voids in the catalyst bed greater than 1 micron diameter to the total volume of the reactor, and has a value of not more than 0.9.  The matrix may be a metal, for example aluminium, or a refractory oxide, for example alpha-alumina, or porcelain. The matrix may be in the form of a skeletal or sponge-like structure, for example, a mass of wires, wire gauze, rods or tubes or spirally wound strips of corrugated or knurled sheet material. Annular particles such as eyelets are also suitable.  The catalyst may be one or more oxides selected from Groups II, III, and IV of the Periodic Table, and may contain one or more elements, or compounds thereof, selected from Groups VIa or VIII.  Halogens and phosphorus may also be present.  If the matrix is of aluminium, the layer of oxide on the surface may be employed as the oxide of the catalyst, if necessary thickened.  In examples, matrices of aluminium turnings or alpha-alumina were employed, coated with gamma-alumina by immersion in an alumina hydrogel and drying, followed by impregnation with ammonium molybdate and cobalt nitrate.ALSO:In the catalytic treatment of hydrocarbon feedstocks employing a fixed bed of catalyst, the catalyst consists of a layer of catalyst material supported on a matrix, the material of which is substantially devoid of pores with diameters below 1 micron, the ratio of the weight of catalyst material to weight of total catalyst being less than 0,5, and also less than \s8/9(1 - \s8), where \s8 is the ratio of the total volume of voids in the catalyst bed greater than 1 micron diameter to the total volume of the reactor, and has a value of not more than 0,9.

Title: Differential drive system
IPC: F16H7/00
Filed: 1975-09-12
Abstract: 1513833 Linkwork HEWLETT-PACKARD CO 12 Sept 1975 [2 Oct 1974] 37578/75 Heading F2K In a serial printer, selective as simultaneous rotary and translational (i.e. linear) movements of a cylindrical-like member 11, to which a print disc (not shown) is attached, is effected by a non-slipping belt, cable or chain 21 which passes around a pair of reversible rotary drive motors 13, 15, the cylinder 11 and a pair of freely journalled pulleys 17, 19 in the pattern shown, the motors 13, 15 and pulleys 17, 19 being securely mounted in the printer's chassis (not shown). Simultaneous rotation of the motors 13, 15 at equal rates but in opposite directions (Fig. 1) results only in pure translation, i.e. linear movement (without rotation) of the cylinder 11 to the left or right depending on the direction of the opposed rotations of the motors 13, 15, whilst simultaneous rotation of the motors 13, 15 at equal rates but in the same direction (Fig. 2) results only in pure rotary movement (without translation) of the cylinder 11 in a clockwise or counter-clockwise direction depending on the directions of rotation of the motors 13, 15. When the motors 13, 15 are rotated at unequal rates in either of the above described modes, the cylinders 11 and hence the print disc will accordingly undergo a combined rotary end translational motion whereby, in use, the print disc may be rotated to an appropriate character, whilst simultaneously undergoing translation to the next desired column location for printing, Fig. 3 illustrating this combined rotary and translational movement of the cylinder 11 effected simply by stationing the motor 13 and rotating the motor 15. In Fig. 4 (not shown) the cylinder 11 is replaced by a bar 31 carrying pulleys 33, 35 around which the belt 21 is additionally wrapped, a pen 37 being carried on the section of belt 21 between the pulleys 33, 35. The arrangement operates exactly as in the above described embodiment of Figs. 1 and 2 to provide either pure translation of the bar 31 and hence pen 37, or pure rotary movement of the belt 21 around the pulleys 33, 35 to effect pure upward or downward movement of the pen 37 or a combination of these movements of the pen 37 whereby the pen 37 and bar 31 arrangement provides an X-Y plotting device. In each of the embodiments of Figs. 1 to 4 the belt 21 is endless, whilst in the embodiment of Fig. 5 (not shown) two separate belts (47, 49) are separately driven by rotary motors (51, 53) and are arranged to drivably contact opposite sides of the cylinders 11.

Title: Signal energy take-off device
IPC: H01F19/08
Filed: 1961-10-20
Abstract: 948,374. Impedance transformation. TEKTRONIX Inc. Oct. 20, 1961 [Nov. 7, 1960], No. 37723/61. Heading H1W. A transforming arrangement for extracting a small amount of energy from a transmission line comprises a number of connecting lines connected, at one end, in parallel across a gap in one conductor of the transmission line and connected in series or in series-parallel to a take-off line at the other end. As shown diagrammatically, the outer conductor of a coaxial line 12, 14 is formed with a gap 26 across which are connected in parallel three groups 32, 24, 36 of connecting lines. These present to the gap a combined impedance much lower than that of the coaxial line. In order to obtain voltage magnification and to match the connecting lines to the take-off line 40, the three groups are connected in series to the take-off line, the three members of each group being connected in parallel. Connecting lines 34 are passed once through an annular ferrite core 42 and lines 36 twice through this core. The core isolates the ends of these connectors from each other and enables the series connection to the take-off line to be effective. A further ferrite core 50 isolates the earthed outer conductor of the coaxial line 12, 14 from the gap 26. In a more complicated arrangement (Fig. 3, not shown), a group of connecting lines is connected in parallel in one direction across the gap 26 and a further group in parallel across the gap in the other direction. The lines in both groups which pass through the ferrite core do so in opposite directions. In this construction it is necessary to provide isolating ferrite rings on both sides of the gap 26.

Abstract: 1,117,447. Terminals. PLESSEY-UK Ltd. 10 Sept., 1965 [16 Sept., 1964], No. 37823/64. Heading H2E. [Also in Divisions E2 and H4] A conductor 1 of an aerial is unreeled through clamping means comprising a fixed outer tubular member 7 and an axially-displaceable inner tubular member 2, said members being held apart by a biasing spring 4 acting upon an enlarged head portion 5 of the member 2, movement being limited by a co-operating gland nut 6. When a stop member 8 which is secured to the conductor 1 reaches the member 2 complementary spherical surfaces 8, 9 engage and the latter member is moved forward so that a tapered nose portion 3 thereof engages with an internal similarly-tapered surface 11 of the member 7. The nose portion 3 is thereby contracted down on the conductor 1, clamping it and making good electrical contact therewith. R.F. signals are applied via a feeder disposed at right angles to the axis of the conductor and so spaced from a metal support 7a for the member 7 that the said support is at a nodal point, so as not to short-circuit the signals.

Title: Improvements in or relating to automatic or semi-automatic telephone exchange systems
IPC: H04Q3/42
Filed: 1929-12-11
Abstract: 344,857. Automatic exchange systems. STANDARD TELEPHONES & CABLES, Ltd. and WRIGHT, E. P. G., Columbia House, Aldwych, London. Dec. 11, 1929, No. 37990. [Class 40 (iv).] A register controller of the kind using a common translating frame, has an out-sequence switch in which each digit is represented by a group of terminals. Prior to the transmission of each digit, the switch is stepped by a single rotation of a common impulse machine a number of steps depending on the value of the digit. Each subsequent rotation of the machine drives the sequence switch a further step, impulses being sent to line until the switch is driven off the multipled terminals when the digit is terminated. The switch then makes one or more idle steps to provide the usual pause. When the office code has been received EA connects SA to b and at the beginning of the next cycle of the machine, SA pulls up, locks and connects SB via sm1 of the out-sequence switch, the first wiper of the BC switch and the common translating frame to one of the numerical wires 1 .. 0. SB thus receives a number of impulses which it repeats to the backstroke magnet SM of the out-sequence switch. At the end of the cycle, SA falls back energizing CC which removes a short circuit from the impulsing springs p. If the final impulse is a long one, SB remains locked after the relapse of SA so that SM is connected to M1 and the sequence switch is driven on in the middle of each cycle. Otherwise SB falls, connecting SM to m2 so that it is not driven until the end. The effect of this is that an odd or the next even number of impulses goes out according as the final impulse from the machine is long or short. When the wiper sm3 leaves the multipled terminals CC falls to stop the digit and SZ pulls up to connect SM to b so that each revolution of the machine drives SM on to provide a definite pause for hunting time. When sm3 leaves SZ, SA is connected up and SM is then driven on in accordance with the value of the next digit. The numerical part of the number is sent in the same way transmission being delayed if necessary until the required digits have been dialled by relays EB .. ED.
