Title: Filter assembly
Inventor: SMITH CLIVE RICHARD
IPC: B01D46/04
Filed: 1991-08-16
Abstract: A filter assembly for removing particulate matter from gas comprises a collection hopper (13) mounted beneath filter elements (14), and a fan (23) which draws gas through the filter elements, said fan (23) being arranged to direct a flow of filtered gas to impinge on an external surface of the collection hopper (13) thereby to tend to vibrate the hopper and promote movement of particulate matter downwards over an internal, inclined surface of the hopper to outlet (22). The fan and hopper may be enclosed by acoustic walls (27), with the gas (air) exiting through a grille (28) and a door allowing a bin (29) to be placed under outlet (22). Filter elements (14) are inward-flow type, from which particles are removed by reverse-flow jets or mechanical vibration. <IMAGE>

IPC: H04B3/54
Filed: 1993-10-26
Abstract: A power line communications amplifier includes a first amplifier (23) which amplifies a transmit signal consistent within a first operating potential range, a second amplifier (52, 59, 61) which provides additional amplification of the transmit signal consistent within a second operating potential range, wherein the second range is larger than the first range, and a transformer (90) which is employed to couple the amplifier transmit signal output by the second amplifier (52, 59, 61) to the power line communications system. A feedback circuit (70, 71, 72) couples the output of the second amplifier (52, 59, 61) to the input of the first amplifier (23) and functions to maintain a low output impedance while the amplifier circuit operates in a transmit mode. Control circuit (14, 40) is coupled to the second amplifier (52, 59, 61) for switching the amplifier circuit from the transmit mode to a receive mode. While in the receive mode, the amplifier circuit presents a relatively high output impedance. <IMAGE>

Patent GB-938194-A (GB)
Abstract: 938,194. Electrolytic devices. UNION CARBIDE CORPORATION. Jan. 8, 1962 [Jan. 19, 1961], No. 613/62. Addition to 901,787. Class 40 (9). [Also in Group XXIII] An electrical integrator comprising an electrolytic cell using a solution of reversible redox system is formed from an assembly of apertured glass or plastic blocks which are fused together to form a container. As shown in Fig. 1, the integrator comprises three glass or plastic blocks 18, 28, 36 provided with apertures 42 which accommodate terminal wires 38 and locating studs 40 of input, shield, read-out and common electrodes 10, 12, 14 and 16. The blocks 18 and 28 have central apertures in which are fitted magnesium silicate or other ceramic inserts 22, 32. A ceramic or aluminium oxide washer 34 is provided for positioning the read-out and common electrodes in close proximity. When assembled, all the terminal wires pass through the block 36 to provide outside connections, and the glass or plastic blocks are fused together and to the terminal wires and studs by controlled heating. A filling tube 44 is included in the assembly for introducing the electrolyte, which is contained in zones formed by recesses 24 on each face of insert 22 and by the hollow insert 32. The recesses 24 are joined by a capillary 26 which minimises diffusion effects between electrolyte concentrations in the different zones. The blocks are formed from uniform particles of a high silica line glass which is pressed into the desired shape. This initial pressing is consolidated by fusing when fired at high temperatures. Alternatively the plastics material polytetrafluoroethylene may be used. The electrodes may be formed from platinium foil, the electrodes 12 and 14 being perforated. Alternatively the electrodes may be made from tantalum carbide or niobium carbide. In a modification, Fig. 2, the locating studs are omitted and the electrodes are positioned by engagement of the terminal wires with recesses 46 in the blocks. In this arrangement an end filler tube 48 for the electrolyte is provided.

Patent GB-2288042-A (GB)
Title: Database management system
Inventor: DUNN STEPHEN
IPC: G06F17/30
Filed: 1995-01-23
Abstract: Changes to a database file 11 are recorded in a journal file 12. The journal file comprises a sequence of after-image records each having a database identifier indicating to which database record it relates. Periodically, a dump 14 is taken of the database. At regular intervals, between dumps the journal file is merged, 15, with any previously archived journal file 13 to form a merged file, the records are sorted into order of their database identifiers and the merged file is filtered, 16, to remove all but the respective latest after-image record relating to each particular database record. The filtered journal file is archived. If the database file is corrupted, it can be recovered by applying the filtered journal file to a dump file. Because the journal file has been filtered, recovery is faster. The filtered journal can also be used for performing an off-line integrity check, 18, on the reconstructed database file. <IMAGE>
