Title: Improvements in or relating to Automatic Frequency Control Arrangements
Inventor: HARROD KENNETH WILLIAM GEORGE
IPC: H03L7/16
Filed: 1965-09-03
Abstract: 1,153,145. Automatic frequency control systems. PLESSEY CO. Ltd. 5 Sept., 1966 [3 Sept., 1965], No. 37721/65. Heading H3A. The output of a slave oscillator 1 at frequency f 1  is supplied to a mixer 2 together with a reference frequency f 2  to produce an output at frequency f 1 -f 2  which is fed directly and through a 90 degrees phase shifter 4 to mixers 3 and 5 where it is combined with a second reference frequency f 3 . If the output from mixer 5 is sin wt, this is differentiated in unit 8 to produce w cos wt which is multiplied by the cos wt output of mixer 3 in the product detector 9. The output of the latter is w cos<SP>2</SP> wt = ¢ w (1+cos 2 wt) and is applied to control the oscillator 1 to reduce the frequency w to zero, when f 1  = f 2  +f 3 . A signal for fine control of frequency may be produced by a phase detector 10 or by the D.C. output of mixer 3. Low-pass filters 6 and 7 are preferably included where shown. The system may be used in a frequency synthesizer.

Classes 123(2) and 123(3) In a boiler comprising a furnace 14 lined with steam generating tubes and fired by burners 16, combustion gases leaving the furnace through a horizontal pass locating a secondary superheater 30, a reheater 32 and a primary superheater 10, the latter is constructed on site from prefabricated tube platens of the form shown in Fig. 2. Each platen consists of eight multiple-bend nested tubes the inlet and outlet portions 102, 120 of which are disposed in a single straight row so that they may pass between tubes 26 lining the roof of the horizontal pass. The portions 102, 120 are welded to junction headers 100, 122 respectively. Below the roof of the pass four of the nested tubes are displaced a short distance from the plane of the portions 102, 120 so that each ulaten consists of two rows of parallel tubes. To complete the superheater, the shop-fabricated platens each comprising the multiple bend tubes and associated junction headers are assembled side-by-side on site. The ends of each of the junction headers 100, 122 are then connected by welded tubes 96, 98 and 124, 126 respectively to main inlet and outlet headers 94, 128 which are disposed transversely above the associated rows of junction headders and the complete unit elevated to its operative position and secured to the appropriate steelwork.

A valve for controlling a connection to a high vacuum chamber comprises a body 1 having a valve chamber for connection respectively to the enclosure at 9 and to an outer space at 8, a movable valve member 30, 40 controlling a seat orifice 31 and having a seating portion 40 made of a metal substantially harder than the metal of the valve body and formed with a sharp generally annular bevel portion 40 adapted to penetrate the softer metal of the body around the orifice 31, and means for applying force to the valve member to effect sealing. An inner conical portion 30 of the valve member engages the wall of the orifice opening 31. Force is applied to the valve member through a differential screw arrangement comprising a screwed valve spindle 29 engaging in a rotatable nut 35 which has an external thread 37 of different pitch engaging a sleeve 38. This sleeve engages the body with a thread 39 of the same pitch as the thread 37 so as to provide an adjustable abutment for the nut 35 to vary the maximum opening of the valve. The valve is sealed by a stainless steel bellows 32 welded to the valve member and to a stationary ring 27. The valve body may, e.g. be of electrolytically pure copper, nickel, high-purity aluminium, or platinum, and the valve member of polished stainless steel or iron nickel alloy. Connectors 10, 11 held by nuts 14, 15 are also provided with sharply bevelled ends 13, 25 which bite into the material of the valve body. These connectors may also be made in a hard iron-nickel alloy and may have a coefficient of thermal expansion equal to that of a selected grade of glass of which pipe extensions to the connectors 8, 9 may be made.

Abstract: 1433533 Data processing system SIEMENS AG 17 Aug 1973 [21 Aug 1972] 39051/73 Heading G4A A data processing system includes a channel unit through which data is exchanged between one or more peripheral devices and a central unit, the channel unit including a counter which is set to a first count when data exchange with a first peripheral begins, whereupon, after an initial address transfer indicating the identity of the peripheral, the data exchange continues without further addresses, and which is set to a higher count when data exchange with further peripherals begins, whereupon, at the higher count, each data exchange is accompanied by the address of the relevant peripheral. The channel unit may include several interfaces with peripherals, each interface having a counter. A store may also be provided for commands and for buffering data to reduce the number of main store accesses required. The counter may be incremented and decremented as peripherals start and stop exchanging data, the way in which exchanges are performed depending on the current count.

Abstract: Membranes formed by the coacervation of a material comprising at least one gelable hydrophilic colloid having amino groups and peptide linkages (e.g. proteins and polyamines) are treated with an aqueous solution of one or more of tannic acid, gallic acid or di-gallic acid to improve their physical characteristics, in particular their impermeability to fluids.  The membranes may be formed by simple or complex coacervation of one or more of the above colloids by any process and they may encapsulate solids, oils, hydrophilic liquid-in-oil and oil-in-hydrophilic liquid emulsions which may contain "active" ingredients which render the preparations suitable as fertilizers, plant growth hormone preparations, bactericides, pesticides, vitamin preparations, medicines and food additives. Treatment is preferably carried out subsequent to the gelling (e.g. by cooling) of the concervate under conditions of time and pH (generally acid) which allow the properties of the product to be varied.  Specified colloids of the above type are gelatine, fibrinogen, polylysine and polyornithine.  Specific examples relate to the treatment of: (a) particles of an aqueous solution of urea-in-corn oil emulsion encapsulated in gelatine with tannic acid, gallic acid and di-gallic acid; (b) a similar preparation comprising 1,2,4,5,6,7,8,8-octachloro-4,17-methano-3a ,4,7, p  7a -tetrahydroindan in place of the urea of (a) with tannic acid; (c) particles of an aqueous solution of chloral hydrate-in-mineral oil emulsion encapsulated in a complex coacervate of gelatine and styrene-maleic anhydride copolymer with tannic acid.
