Title: Antenna systems
IPC: H01Q3/46
Filed: 1974-08-22
Abstract: 1485491 Aerials SIEMENS AG 22 Aug 1974 [23 Aug 1973] 36877/74 Heading H4A The Specification describes a phase controlled antenna system having a plurality of elements arranged in one plane in rows and columns wherein adjustment of the phase supplied to the elements is by electronically variable digital phase shift devices, and is of the kind described in Specification 1,333,479. Although the embodiment described relates to a radiation fed system as in the Specification referred to, it is stated that the invention may be related to other phase-controlled antenna systems and also to a radiation-fed monopulse system wherein two or four feeder horns are used. In the present invention, the focusing phase values ## required to produce transmission of a plane wave beam at any given operating frequency are stored in an accumulator group store, so that the focusing phase ## may be called up for any frequency desired whilst the deflection phase values # a  required for a specific beam direction are computed in a common phase computer for each antenna element, each individual phase shift device being provided with a device for adding the particular value of ##, which has been called up, to the computed value of # a  for the associated antenna element. Several arrangements of the actual disposition of elements on the planar array are given, Fig. 6 (and Figs. 3-5, not shown), wherein the number of phase shift devices are thinned out with respect to the homogeneous array (Fig. 3), In Fig. 6, the radiation from feed horn 6 falls on a smaller area, homogeneous array 6, while the radiating elements are thinned out and occupy a larger area. A phase computing arrangement is described with regard to an arrangement such as Figs. 1 or 6 (or Fig. 3). In Fig. 7, guidance data from a central computer containing horizontal and vertical deflection data and operating frequency data, is converted in control data generator 20 into control data signals, which are applied to a phase computer 21 consisting of a vertical computer 22 and horizontal computers as described in Specification 1,333,479, but there is in addition included an accumulator group 24 and an adder group 25. The respective deflection phase signals #a from 23 are added to the respective focusing phase signals ##, which are stored in accumulator 24 and called up in response to frequency signal F, in a respective adder 25, located at each digital phase shift device 26 associated with each antenna element, which arrangement is stated to reduce the complexity of the phase computer.

Patent GB-809651-A (GB)
Title: Fluid flow control apparatus
Inventor: LEE NORMAN
IPC: F16K31/363
Filed: 1954-12-22
Abstract: 809,651. Valves. KEELAVITE CO. Ltd. Dec. 8, 1955 [Dec. 22, 1954], No. 37095/54. Class 35. When fluid enters the valve 14 through pipe 11 it experiences a pressure drop across the adjustable metering orifice 13 whilst the input pressure is transmitted to a chamber 25 via a conduit 47 leading from the pipe 11 at a point upstream of the orifice 13 and embodying a constriction 48; the lower end of a piston 23 engages a cup-shaped member 33 and its movement is opposed by an associated adjustable spring 31; the upward movement of the member 33 is limited by flanges 37, 38. When a pressure increase occurs, the lower pressure, downstream of the orifice 13, is transmitted to the fluid in an inlet chamber 18 and thence to a lower chamber 26 by way of a T-shaped passage 44 in the piston 23 where it opposes the pressure in the upper chamber 25 urging the piston down; the resultant force moves the piston 23 downwards to restrict the flow through the port 20 to the outlet 16 until the equilibrium is reached so reducing to a minimum fluctuation in the rate of flow. In a similar manner if the direction of fluid flow through the valve is reversed any inlet pressure increase will result in the piston 23 being subject to a resultant force which moves it against an upper adjustable spring 30 and causing the lower end of the piston to restrict the port 20 and reduce the flow rate since the lower pressure, downstream of the orifice 13, now acts on the upper end of the piston. Irrespective of the direction of flow the orifice and valve are in series and any change in the rate of flow produces a pressure drop across the orifice which causes a movement of the piston in a direction tending to restore the flow rate to its original value. In a modification, the orifice is of fixed crosssection and is formed in a plate threaded in the passage 15 adjacent the chamber 18; a plug 50 in a passage 49 is thus removed and the pipe connection 46 replaced by a plug so that the passage 49 will place the side of the orifice remote from the valve in communication with the chamber 25, via the passage 45.

Patent GB-791634-A (GB)
Title: Process for the production of ethylene and its gaseous homologues
IPC: C07C11/04
Filed: 1955-12-28
Abstract: Ethylene and its gaseous homologues are obtained by conducting a petroleum distillation residue containing a preponderance of constituents which boil at temperatures higher than 360 DEG  C. and have a single or condensed cyclic structure, by means of a carrier gas consisting of hydrogen, or a mixture of hydrogen and nitrogen, through a space or chamber filled with stationary solid heat carriers where thermal cracking of the residue takes place at temperatures between 850 DEG  and 1000 DEG  C.  If hydrogen gas only is used as the carrier gas it is constantly removed together with methane and its homologues which are always found in thermal or catalytic cracking of hydrocarbon mixtures after the ethylene and its homologues have been separated.  If hydrogen and nitrogen are used then the ratio between the 2 gases is preferably so chosen that one part of nitrogen is used to every three parts of hydrogen.  In a typical example, hydrogen was used as the carrier gas and the cracking temperature was 860 DEG  C. and the length of stay in the cracking zone was 0.2 seconds.  The yield of ethylene was 34.5 per cent by weight.

Title: Sheet registration device
IPC: G03G15/30
Filed: 1965-09-02
Abstract: 1,122,621. Feeding sheets. RANK XEROX Ltd. 2 Sept., 1965 [30 Sept., 1964], No. 37585/65. Heading B6B. A sheet registration device 45, described as applied to mechanism adapted to feed sheets to a printing drum in a xerographic apparatus, comprises front register stops 513 secured on the shaft 514 of one feed roller 511 which is driven and co-operates with an idler roller 512, which is biased towards the roller 511, the roller 511 being driven at a speed which varies cyclically by a shaft 517 which is freely mounted within the shaft 514 and is connected to the latter through a variablespeed drive. In this arrangement, the front stops 513 are rapidly advanced into the path of travel of a sheet, then rapidly retarded to effect alignment and registration of the sheet, and the two shafts are then driven at the same angular speed to cause the sheet to be fed towards the printing drum at a speed equivalent to the peripheral speed of the drum. The constantly-driven inner shaft 517, Fig. 2 and Figs. 3a to 3e (not shown), has secured thereon a drive arm 524 carrying a gear segment 523 which meshes with a gear segment 522 secured on the outer shaft 514, and a cam follower 525 on the segment 523 engages a fixed cam 526. The arm 524 is connected by a coil-spring 527 to the gear 522, so that the follower 525 is biased towards the cam 526. The shape of the cam 526 determines the speed variation between the two shafts 514, 517. The idler roller 512 is mounted on a shaft 531 journalled in arms 532 which are rocked about a rod 533 by cams 515 secured on the outer shaft 514, whereby the two feed rollers are separated during registration of a sheet. Both the feed rollers comprise a series of discs. The inner shaft 517 is driven from a clutch sprocket 551 (Fig. 2) by means of a drive arm 530 which is secured to the shaft and has a bent end engaging an aperture in the sprocket. The registration device 45, which forms a unit with feed means which deliver a sheet from the printing drum to a fuser device, can be readily disconnected fron the drive sprocket 551, and the whole unit can be removed from the machine. The sheets are separated from the top of a stack and forwarded to the registration device 45.
