Abstract: 842,367. Radio signalling. GENERAL ELECTRIC CO. Ltd., and GRIFFITH, G. W. S. Jan. 3, 1958 [Oct. 3, 1956], No. 30182/56. Class 40(5). Relates to a radio repeater station in a system providing two separate communication channels using different radio frequencies between terminal stations, both channels passing the same intelligence, the repeater station comprising a first radio receiver and transmitter associated with one of the channels and a second radio receiver and transmitter associated with the remaining channel during normal operation, means being provided which is responsive to the signals supplied by the respective receivers which operates when one of those signals is qualitatively poorer than the other to disconnect the corresponding receiver from its associated transmitter and to supply that transmitter with a signal from the remaining receiver. As shown the repeater station is provided with resistive T-networks 15, 16, connected between the receivers 7, 8, and their corresponding transmitters 9, 10, each of the networks being arranged to give an attenuation of 6 db. The output impedance of each receiver and the input impedance of each transmitter is 75 ohms and the resistors 17, 18, in the series arm have a value of 25 ohms and the resistors 19, 20, in the shunt arm values of 25 and 75 ohms respectively. Each of the receivers 7, 8, is provided with means to assess the signal passed to the corresponding transmitter 9, 10. If the assessment shows that one of the receivers say receiver 8, is faulty or receiving a poor signal, a relay B Fig. 5 (not shown) is operated and changeover contacts B1 disconnect the transmitter 10 from the attenuation network 16 and connect it via changeover contact B2 to the network 15, the same level of signal being fed to both the transmitters. Similarly, a relay A Fig. 5 (not shown) is operated when the output of the receiver 7 is of poor quality. In a modification, Fig. 3 (not shown) each receiver feeds two similar amplifiers the output of one amplifier being passed via a 6 db. attenuator and a relay changeover contact to a corresponding transmitter and the output of the second amplifier being passed via an attenuation network of the type shown in Fig. 2 to a demodulator forming part of a supervising circuit. If the output signal from a receiver in one channel is of poor quality a relay is operated and its corresponding transmitter is then supplied from the attenuating network supplying the supervising circuit for the other receiver. The I.F. amplifier for each channel is provided with automatic gain control, the A.G.C. voltage being utilized to control the respective relays. An interlock may be provided to prevent either of the relays A and B from being operated when signal levels provided by both receivers 7 and 8 are low.

Title: A process of deagglomerating dried agglomerated microspheroidal gel catalyst particles
IPC: B01J21/00
Filed: 1954-10-20
Abstract: Dried agglomerated micropheroidal gel catalyst particles are pneumatically separated into product and oversize material, followed by impacting the oversize particles to effect deagglomeration without fracturing the individual microspheres, and recycling the impacted particles to the pneumatic separation step.  In a modification, the particles are subjected to imparting before the separation step.  The invention may be used in the treatment of spray-dried silica-alumina, silica-magnesia, or silica-alumina-magnesia gel cracking catalysts. In examples, a hydrated gel slurry containing 6-8 per cent silica and alumina is spray dried and fed to a mechanical air separator.  The oversize fraction containing agglomerates is imparted in an apparatus comprising a horizontal rotor shaft carrying hammers; anvils or breaker plates are mounted within a casing surrounding the shaft, but the hammers and anvils are arranged in such a way that the particles rebound freely from the striking surfaces and are not crushed.  In apparatus shown diagrammatically, two air separators are arranged in series, the oversize material from each being passed to the impactor and then mixed with the feed to the first separator.  The product may contain only a small proportion of particles larger than 80 microns diameter or smaller than 20 microns diameter.ALSO:Dried agglomerated microspheroidal gel catalyst particles are pneumatically separated into product and oversize material, followed by impacting the oversie particles to effect deagglomeration without fracturing the individual microspheres, and recycling the impacted particles to the pneumatic separation step.

Abstract: 1381640 Rotary disc filter CHEVRON RESEARCH CO 28 June 1972 [2 July 1971 2 Dec 1971] 30359/72 Heading B1D [Also in Division C5]  A relatively dilute pumpable slurry is concentrated by means of rotary disc filter apparatus. The apparatus comprises a double walled housing 38 which has a tangential inlet 35 for slurry to be concentrated and a tangential outlet 36 for concentrated slurry. Fluid may be passed between the walls of the housing by inlet 40 and outlet 39 to effect temperature control. The housing contains a stack of filter discs 31 mounted for rotation on hollow shaft 30 which also acts as a duct for passage of filtrate to outlet 13. The discs each comprise a solid plate and a stainless steel filter screen defining therebetween a hollow chamber 34 connected to the interior of shaft 30. The chamber 34 may contain two layers of larger mesh screen on a support. In use, slurry is pumped into the housing, and a differential pressure is maintained between slurry and filtrate whilst the filter discs are rotated at a speed to give a peripheral centrifugal force of 10-100g. The filter screens may alternatively be formed of cloth or plastics material. The use of the apparatus is described for the separation of crystallised, e.g. p-xylene, solids from mother liquor, wherein the relatively dilute slurry is delivered to the filter apparatus from a crystallization zone and the concentrated slurry output is divided into two portions, one being returned to the crystallization zone and the other to a centrifuge for separation of solid and liquid.

A tool for crimping connectors to electrical conductors, Figs. 3 and 6 (not shown), comprises jaws 13, 14 operated, through means having a changing mechanical advantage, by a piston 3 supplied with compressed gas. An increasing mechanical advantage as the jaws close may be provided by a cam (210), Fig. 13, (not shown), or by toggle links 17, 18 connected to the pivoted jaws 13, 14. Thus the supply of nitrogen from a bottle 26 remote from the tool or mounted thereon may be interrupted by closure of a valve 50, Fig. 12, before the piston has completed its stroke, expansion of the gas already in cylinder 2 being sufficient with the increasing mechanical advantage to complete the crimp. A valve 34 in the bottle 26 is opened by a stem 37 as the bottle is fixed on the tool, supplying the gas along passages 38, 39, 40 to a valve 41 which may be opened by a button 43 to feed the gas into a valve chamber 49 from which it passes into the cylinder 3. The gas lifts the valve 50 so that it follows the piston 3 for part of the pistonstroke before encountering a seating 53 and interrupting the supply to the cylinder. A safety ring 56 surrounds the tool and has an opening for alignment with the button 43. A relief valve may be provided in the end fitting 27 of the bottle 26. A holder 60, Fig. 15, with a long handle (58), Fig. 14 (not shown), may carry the tool with the button 43 aligned with a pin 61 operated by a bevelled plunger 65 from the lower end of the handle.
