Title: Screen for fish tank outlet
Inventor: GODDIN JEREMY ROBERT
IPC: A01K63/00
Filed: 1990-02-13
Abstract: A cylindrical screen prevents the escape of fish or other aquatic animals into an outlet (34) of a tank and comprises a sheet of welded stainless steel wire mesh (37) rolled into a tube with its longitudinal edges secured together. Lower and upper sections (38 and 39) of cylindrical piping are fitted into the ends of the wire mesh tube (37) and are held in position by contractile clips. The lower section (38) is a push fit into the tank outlet (34) whilst the upper section (30) stiffens the upper end of the wire mesh tube and extends to above the maximum water level (19) in the tank. The upper end of the lower section (38) is at a level (X-X) above the tank bottom (14) to provide a dead zone for the deposit of particles to be sucked through a separate drainage system. <IMAGE>

Title: A drive system for a mechanical part of an image forming apparatus
Inventor: IWAO NAOTO
IPC: G03B27/62
Filed: 1990-06-21
Abstract: A drive system includes an ultrasonic vibration device 2, Fig 2, 102, Fig 4, which when supplied with electric signals, a contacting part 111 of this device is caused to vibrate and to engage a mechanical part so as to intermittently drive the part in a given direction. The device may have piezoelectric elements 112A to cause longitudinal vibration of an elastic member 110 and piezoelectric elements 112B to cause transverse vibrations. Alternatively electrostrictive or magnetostrictive devices may be used. The ultrasonic vibration device 2, 102 is described used to drive a drum 1, or belt (113, Fig 2) of a photocopier. Further the ultrasonic drive system can be used to linearly move a developing solution tank (Figs 5, 6, 7A and 7B), to rotate a squeezing roller (420, Figs 8 and 9) for removal of surplus developing solution, and for retracting a pre wet roller (524, Figs 10 and 11). Also the ultrasonic drive system may be used to move the optical system (Figs 12-14) and the original tray moving device (Figs 15-18) of the photocopier. <IMAGE>

Title: Feeding arrangements for multicolour thermal ink ribbons
Inventor: YOROZU HIDEKI
IPC: B41J35/16
Filed: 1990-07-19
Abstract: In a thermal printer of the kind in which an ink ribbon is supplied from a first reel and taken up upon a second reel and is fed between a printhead and the paper to be printed upon, and in which the ink ribbon comprises successive lengthwise portions of different colours in a repeating sequence, and wherein each separation zone between succeeding differently coloured portions is coded by associating its length with the identity of the colour immediately following it; a ribbon sensor is disposed at a fixed distance upstream of the point of printing, and the lengths of the separation zones are measured thereby in association with the quantity of ribbon fed past the sensor, and the amount of ribbon fed to bring the start of a new colour zone to the point of printing is calculated in accordance with the measured amount of feed required to pass its respective preceding separation zone of known length past the sensor. Thus the difference in the amount of ribbon fed per unit angular rotation of the take up reel between an empty reel (small feed per angular increment) and a full reel (large food per angular increment) can be compensated for when indexing from colour zone to colour zone.   <IMAGE>

Title: Vibrational method of and apparatus for detecting defects in an object
Inventor: TSUBOI KIYOSHI
IPC: G01M7/02
Filed: 1991-04-03
Abstract: A test object 21 such as an engine cylinder, is inspected for any defect such as a crack, a blowhole, a cavity, or the like by applying vibration to the test object in at least two different positions on a side thereof. While the test object is vibrating, signals indicative of the vibration of the test object are detected. From the detected signals, there are produced a signal indicative of natural vibration of the test object and a signal indicative of defect-induced vibration of the test object. The signal indicative of natural vibration and the signal indicative of defect-induced vibration are compared to determine whether there is a defect in the test object. The different positions are angularly displaced when the object is of circular cross-section. <IMAGE>

Patent GB-913592-A (GB)
Abstract: 913,592. Fuel cells. IMPERIAL CHEMICAL INDUSTRIES Ltd. March 18, 1959 [March 26, 1958], No. 9673/58. Drawings to Specification. Class 53. A fuel cell in which hydrogen and oxygen are led through porous electrodes into an alkaline electrolyte, for example a 30% solution of caustic potash, has at least one electrode the surface of which consists of titanium carrying a deposit of platinum, palladium or other metal of the platinum group. Platinum may be in the form of platinum black and it may be deposited on an undercoating of smooth platinum applied to the titanium by electroplating, as described in Specification 877,901. Both electrodes may be made in this way; or the positive electrode to which oxygen is supplied may be made of porous nickel. The two electrodes divide the cell into three compartments, the middle one containing the electrolyte, the hydrogen and oxygen being led into the outer compartments where they become ionized at the electrode surfaces and set up a potential difference between each electrode and the electrolyte. The gases pass into the electrolyte through the electrodes, the pores of which have a diameter of about four microns. Deterioration of the cell may be caused by absorption of hydrogen in the cathode and this may be corrected by interchanging the gas supplies at regular intervals, or by passing a current through the cell to liberate oxygen at the cathode. Electrodes may also be made in the form of a platinized column of compacted titanium powder.

Title: Generating a slurry by shearing teemed molten metal
Inventor: HENDERSON STEVEN
IPC: B22D11/112
Filed: 1993-01-14
Abstract: A metal slurry is generated from a liquid metal being teemed by applying a high rotary shear rate in the region of a solidification front thereof. The metal is teemed through an annular apparatus and either the inner or outer wall of the annulus can be cooled and rotated. In Fig. 1 the slurry generator has a static core 2 surrounded by a rotating outer drum 3 with the liquid metal flowing through the annular space 11 therebetween. The outer drum is rotated at a speed so as to create a shear rate of greater than 5N/m<2> at the liquid front. The creation of a high shear stress and shear rate in the liquid metal adjacent the solidification front of the metal contributes to the formation of a slurry by promoting the formation of dendretic solids in the liquid metal and by increasing the rate of heat flow out of the metal. <IMAGE>
