Title: Vacuum drying apparatus
IPC: F26B5/04
Filed: 1980-02-05
Abstract: The present invention relates to material drying apparatus particularly for drying heat sensitive materials and foodstuffs, the drying being effected under vacuum conditions. The apparatus includes an elongate vacuum chamber 2 partitioned into a number of drying sections, and material to be dried is fed through the sections from an inlet to a discharge by means of a vertical array of parallel endless bands 5. A first drying section utilises conventional conduction or radiation drying, e.g. hot plates 10, using heating medium such as steam, to remove the bulk of the liquid, while for the final stage of drying microwave heating is employed in a second drying section. The microwave drying means includes two separate microwave input units 12, 13, located at opposite edges of the bands and axially spaced. The units which comprise a plurality of vertically arranged microwave elements face over the parallel bands, and the form and arrangement of the microwave units provides for efficient drying in the microwave section. <IMAGE>

Title: Slit nut
IPC: F16B37/00
Filed: 1980-07-31
Abstract: In certain corrosive situations conventional nut and bolt assemblies can become frozen whereby it is impossible to remove the nut from the bolt.

Title: A process for the separation of contaminants from feed streams using magnetic beds
IPC: B01D53/26
Filed: 1980-09-04
Abstract: Contaminants are removed from a fluid stream 7 in a continuous process by adsorption on fluidized solid adsorbents 3, particularly small particle size adsorbents, which also include a magnetizable component, and are desorbed in a vessel 21 wherein the adsorption and desorption are carried out at substantially the same pressure. The adsorbent particles and magnetizable component 3 flow through the vessels and are stabilized against fluid by-passing and solids back-mixing and recirculation generally associated with fluidized beds (except for the flow or movement of the solids through the contacting vessels) during adsorption and desorption by the use of magnetic fields (applied by means 5 and 5a). Numerous adsorption processes are exemplied including the removal of acid gases or other polar materials from gas streams, e.g. from combustible or refinery gases, and the separation of hydrocarbon mixtures. <IMAGE>

Title: Radar arrangements and methods
Inventor: SINNOCK PETER JAMES
IPC: H01Q3/08
Filed: 1980-12-04
Abstract: A radar arrangement has an aerial system providing two alternative radiation patterns. The transmitter/ receiver unit 14, rotatable by a drive unit 12, projects an elongate radar beam onto a reflector 18 which rotates with the unit 14. The reflected beam therefore scans the target area. The reflector 18 is switchable about the vertical axis through 90 DEG  with respect to the unit 14. In one position, the beam is therefore projected into, and scans, the target area with its elongate dimension vertical -A, fig, 1 (so as to be best suited to detect rapidly approaching targets of small aspect such as aircraft or missiles), and in the other position the beam is projected into, and scans, the target area with its elongate dimension horizontal -B, fig, 1 (so as to be best suited to detect intermittent targets appearing in relatively slow moving positions such as the rotor blades of a helicopter). <IMAGE>

Abstract: The temperature of the hot air (22) emerging from a cowper of an installation for the production of hot air is controlled by mixing cool air from the main supply pipe (16) with the hot air produced in the chamber (34) during the air cycle. A pipe (30) with a regulating valve (32) leads the cool air to valves (26) in the cowper burners (10) and so into the chamber (34). Valves (32 and 26) are regulated to maintain the desired temperature of the hot air output. <IMAGE>

Title: Seal assembly
IPC: F16J15/34
Filed: 1981-03-31
Abstract: A seal assembly for sealing a rotary shaft (1 )to a stator (2) into which the shaft extends to contain a fluid within the stator is described. The assembly comprises a first annular sealing surface (10) provided by a spring loaded first sealing member of relatively hard material which is carried by the stator (2). The first sealing surface (10) surrounds the shaft (1) and faces along the shaft in a direction away from that in which the shaft extends into the stator. A second, annular sealing surface (32) is provided by a second sealing member of relatively soft material which is carried by the shaft (1). The second sealing surface (32) surrounds the shaft (1), and slidably, sealingly engages the first sealing surface (10). The relative hardness of the first and second members is such that the two sealing surfaces (10, 32) can bed-in on initial sliding engagement. The second sealing member is split diametrically, the two halves being connected by bolts 25. A scale 35 may be provided such that the wear of the second sealing member may be indicated. Alternatively the second sealing member may be provided with visable counterable indicia. <IMAGE>
Patent GB-2084975-A (GB)
Title: Carbon fibres
IPC: D01F11/16
Filed: 1981-05-08
Abstract: A process is provided for the formation of carbon-fibre precursor materials, primarily of acrylonitrile units (with increased modulus of elasticity and strength as well as decreased diameter. Preferably, the material is acrylonitrile, typically copolymerized with a minor amount of an acrylic monomer such as methyl acrylate) by oxidation of the fiber at an elevated temperature in the presence of a carboxylic acid, or its anhydride within the fiber. The acid and/or its anhydride which is formed at the oxidizing temperature, serves as a plasticizer and reduces the fiber yield stress and increases fiber plasticity so that the fibers may be drawn by as much as 300% or more in the presence of the acid and/or its anhydride during oxidation, thereby providing improvement in increased elasticity and strength.

Title: Nuclear magnetic resonance detection device
IPC: G01C19/60
Filed: 1981-06-23
Abstract: A nuclear magnetic resonance detection device senses angular velocity and comprises cell 28 containing at least one nuclear moment gas 62 and two optically pumpable substances 60 and 61 of different alkali metals or different isotopes of the same alkali metal. Circularly polarized pumping in light 64 and steady magnetic field 68 cause magnetic moment alignment of the nuclear moment gas nuclei and of the atoms of the two optically pumpable substances. Alternating magnetic field 70 causes the nuclear magnetic moments of the gas nuclei to precess. Detection light 66 is modulated by interaction with one of the two optically pumpable substances. The modulation detected at the output of photodetector 40 is representative of angular velocity of the device. <IMAGE>

Title: Improvements in or relating to the case-hardening of metal components
Inventor: DORN MICHAEL THOMAS
IPC: C21D1/06
Filed: 1981-12-17
Abstract: A method of case-hardening a steel component, such as a beater 13 for a hammer grinding machine, comprises forming in part of the surface to be hardened a plurality of holes 20 before subjecting the component to the case-hardening process whereby, during the case-hardening process, the interior surfaces of the holes 20 are hardened, to the normal case-hardening depth, in all directions into the body of the component. There is thus formed a carburised "island" around each hole, and the effect is as if the component had been case-hardened to a depth equal to a depth of the holes in addition to the normal case-hardening depth. <IMAGE>

Title: Hydraulic boosters for vehicle braking systems
IPC: B60T13/14
Filed: 1982-04-22
Abstract: In an hydraulic booster for a vehicle braking system a boost piston (3) provides an output force in response to pressurisation of a boost chamber (5) under the control of boost valve (6) which controls communication between the boost chamber (5) and a pressure source (63) and the boost chamber (5) and a fluid reservoir (64). The operation of the boost valve (6) is controlled by pressure in a control chamber (10) which is pressurised by operation of a pedal-operated input piston (11). A recuperation valve (14) controls communication between the boost and control chambers, and is closed on movement of the input piston (11). Pressure in the boost chamber (5) acts on the input piston (11) to urge it in a direction to keep the recuperation valve (14) closed. This enables the input piston (11) to work in a bore (12) in the boost piston (3), with the control chamber (10) in the boost position (3) and forward of the boost chamber (5), to provide a simple, short booster. <IMAGE>
