Patent GB-2040364-A (GB)
Title: Extended-length vertical axis cantilever shaft volute pump
IPC: F04D29/04
Filed: 1979-03-29
Abstract: The shaft 11 is journalled in bearings 24,25 adjacent its upper end and has an impeller 12 on its lower end submerged in the fluid to be pumped. The extended length of the shaft 11 is achieved without increasing the bearing supports for the shaft or diameter of the shaft, by the use of a gyroscopic mass Mg, which may be spaced upwardly from the center line of the impeller 12 a distance equal to the spacing of the center line of the lower bearing 25 from the center line of the impeller of a conventional cantilever shaft pump in which the impeller is laterally unsupported. The gyroscopic mass resists any force on the shaft and impeller tending to change the axis of rotation of the shaft and thereby retains the natural frequency of the combination of the shaft and the impeller at the same value as with a shorter shaft not provided with the mass and whose unsupported length is equal to the length of that portion of the extended- length shaft which extends between the mass and the impeller. <IMAGE>

Title: Nail driving tool
IPC: B25C1/00
Filed: 1979-07-12
Abstract: An improved electric fastener driving tool (10) includes a body (12) having ahead (14) and a handle (16) and a fastener magazine (18) pivotally connected to the body. A push button (62) for energizing the tool is engageable by a safety mechanism (64) to prevent actuation. The safety mechanism is moved out of engagement with the push button (as shown) upon pivoting of the magazine about the pivot (20) when the tool is applied to the workpiece. The magazine includes a pusher assembly (122) defined in part by half portions (126) of an elongated tube joined together to define a gap which holds nails (130). A pusher (128) is slidably mounted within the gap and biased to push the nails (130) toward the nose of the tool. The magazine also includes a fastener track (164) that includes a reduced portion (171) and an enlarged portion (172) to accommodate nails of different sizes. A V-shaped shoe (178) is releasably attached to the bottom portion of the magazine for use with a V-grooved workpiece and has a raised portion (184) at one end which may be positioned adjacent the head, by reversing the shoe, to prevent the striker (28) engaging and damaging the V-groove of the workpiece. The shoe may be replaced by a flat bottomed shoe when the tool is to be used with a flat workpiece.   <IMAGE>

Title: Heating and transporting a web of film of thermoplastic synthetic material
IPC: B29C51/10
Filed: 1979-08-02
Abstract: In a process for automatic thermal moulding of a thermoplastic synthetic material, a web of film of the synthetic material is transported by entraining members travelling along two guide rails (12) past a heating station to a moulding station. To counteract wrinkling of the web due to thermal expansion, the guide rails (12) are divergent during normal operation. When the web is cool, such as at the start of the process or during an operational interruption, the guide rails (12) are movable to be parallel so as not to expand the unheated web. The moving of the guide rails (12) is effected by means of a threaded spindle (14) carrying two threaded sleeves (19) to each of which is fixed a piston. A double-acting cylinder associated with each piston is connected to the respective guide rail (12) for moving it under the influence of pressurized fluid. <IMAGE>

Title: Bridge Type Converter
IPC: H02M7/501
Filed: 1979-09-21
Abstract: Each diagonal of a bridge type converter comprises the serial interconnection of two semiconductor switches (59, 60 etc.) and a diode connected between a reference potential and the junction of the respective switches. By operating individuals or pairs of switches in various diagonals, outputs of zero, +E, +2E, -E, -2E across the load (67) are achieved, and by given sequences of these outputs stepwise synthesis of AC waveforms is achieved. Protection of individual switches is gained by the clamping action of the diodes preventing open circuit switch breakdown. By extending each diagonal to include further switches and respective reference potentials (Fig. 5) very high voltage outputs and multiple step synthesis are achieved. <IMAGE>

Title: Fluidized bed fuel burning
IPC: F23C10/00
Filed: 1980-04-18
Abstract: A fluid bed combustor (200) for burning coal comprises a first fluidizing zone into which the coal is fed through inlet (232) and a second fluidizing zone into which sorbent is fed through inlet (258) and located downstream of the first zone. The two fluidized zones are connected by a plurality of combustion gas passages with bubble caps (246) surrounded by stones (250) arranged to reduce the velocity of gases passing therethrough and thereby prevent excessive fracture of the sorbent particles.

Title: Infra red imaging device
IPC: H04N3/09
Filed: 1980-07-09
Abstract: A scanning arrangement for an infra-red imaging device in which a column of I.R. detectors, and similarly a column of L.E.D.'s, scans a field broadside to produce a band of parallel line scans, a number of such band scans being provided to cover the field. Each band scan is performed by a respective mirror facet of a rotating polygonal drum, the facets being tilted at slightly different angles to provide the band displacement. Non-uniformity of the column of I.R. detectors or the L.E.D.'s or the interconnecting channels tends to produce the same pattern of non-uniformity within each band. This is overcome according to the invention by periodically tilting the drum by a random fraction of a bandwidth so that on successive occasions a particular element of the field is processed by different detector/L.E.D. channels. <IMAGE>

Title: Comminuting apparatus
IPC: B02C18/14
Filed: 1980-08-19
Abstract: The roller 1, 2 of a roller crusher are driven by respective hydrostatic drives 12, 13, 14; 22, 23, 24. When a lump of rock causes jamming, control means 6 controlled by the oil pressure, causes the reversal of the rollers for a predetermined time and then reintroduces forward rotation of the rollers. Between the forward and reverse rotations there may be a stoppage for a predetermined period during which maximum operating pressure is maintained so as to give the rollers a longer opportunity to crush the lump of rock which is causing jamming. Thus the machine may be protected from damage and its productivity may be increased in the absence of any breakdown. Cleaning combs (7 Fig. 3 not shown) and lateral cleaning openings 8 may be provided. To prevent an output funnel 9 from clogging it may be constructed as a vibrating conveyor.   <IMAGE>
