Title: Designer's filing system
Inventor: PUDDICOMBE CHERRY ANNE
IPC: A47B63/02
Filed: 1990-03-02
Abstract: A filing system whereby the means of retrieving and storing information is available to each compartment within the file on three open sides 25. 26. 27. 28. and a top capacity pocket which is open on one side only 29.. Access to the compartments is through a tabbing system 17. 18. 19. 20. which lifts up the top of the compartment and which also has the facility for renewable sticky labels 21. 22. 23. 24.. Depth of each compartment and the overall size of the file can be variable at the manufacturing stage. The file stacks one on top the other when not in use and is identified by a renewable sticky label on the back or spine which faces outwards. The compartments are held together by rivets and the top pocket is glued. <IMAGE>

Title: Energizing track-running toy vehicles
Inventor: SHODA YUKIO
IPC: A63H17/26
Filed: 1990-03-16
Abstract: A wind-up device for a motor in a toy vehicle which runs on a track includes a track recess which is aligned with the vehicle drive wheels 38 when the vehicle is held at the wind-up station. An electric motor drives a roller 36 beneath the recess so as to rotate the drive wheels 38. An arm 24, 42 above the wind-up station can be depressed to both close the electric motor circuit and press down on the vehicle so that the drive wheels are rotated and energy is stored within the vehicle's motor. On releasing the arm, the motor circuit opens, but abutment 44 still holds the vehicle. Depression of a release button then permits a further rise of the arm and the vehicle moves off along the track. <IMAGE>

Patent GB-2251775-A (GB)
Title: Heat generation by ion-accelerated energy transfer
Inventor: ASPDEN HAROLD
IPC: G21B3/00
Filed: 1991-01-12
Abstract: Deuterons are absorbed into a palladium cathode 8 in an electrolytic cell containing a heavy water solution 5 and a strong electron current supplied by a transformer 2 flows through the cathode. Anomalous energy transfer from electrons to protons generates heat from passage of hadronic deuteron ions through a cathode composed of alternate sections of palladium and another metal which is relatively impervious to deuteron absorption. The deuteron is said to be negatively charged for most of the time and its speed and energy escalates enormously in an exponential manner. A net production of energy is apparently achieved, even if iron replaces palladium and protons replace deuterons. <IMAGE>

Title: Exhaust system
Inventor: MA THOMAS TSOI-HAI
IPC: F01N3/20
Filed: 1991-04-24
Abstract: An exhaust system for an internal combustion engine, comprises a down pipe (14) for connecting an exhaust manifold of the engine to a main catalytic converter and a supplementary catalytic converter arranged in a path connected in parallel with the down pipe (14). The supplementary converter has an annular passage defined between inner (18) and outer tubular (16) walls which contains a catalytic matrix (20) and communicates with the interior of the down pipe (14) at its upstream and downstream ends.

Title: A mine roof support system
Inventor: NAYLOR RICHARD ARTHUR
IPC: E21D23/08
Filed: 1992-04-24
Abstract: The mine roof support system includes a roof support anchored to a conveyor or other rigid structure. The roof support comprises a roof engageable member connected to a floor engaging base 17 by a guide linkage 23, 24 and by hydraulic props 20. An advancing mechanism 31 is provided for advancing the roof support relative to the conveyor. The advancing mechanism is mounted with respect to the base of the roof support so as to be substantially torsionally rigid therewith and is anchored to the conveyor for pivotal movement about an axis parallel to the direction of advance of the roof support. An hydraulic ram 64 is provided between the conveyor and the advancing mechanism for pivoting the advancing mechanism about the aforesaid axis. It is therefore possible to maintain the roof support in an upright position despite forces induced by "out of square" contact between the mine floor and a roof structure. To provide torsional rigidity between the advancing mechanism and the base, the advancing mechanism may include an elongate box section member 33 mounted about an advancing ram 32 and slid able in box section guides 34 in the base of the roof support. <IMAGE>

Title: Developing device for image forming equipment using a one component type developer
Inventor: SUZUKI KOJI
IPC: G03G15/08
Filed: 1993-01-08
Abstract: A developing device using a one component type developer wherein the developer is transferred from developer supply roller 5 member to developer roller 4 which are rotated to move in the same direction at a position where they contact each other. This prevents the developer from a toner store from directly reaching part of the developer roller 4. Roller 4 has conductive portions 42 connected to ground and dielectric portions 41 distributed regularly or irregularly on the surface. The surface of the developer roller 4 is charged by friction by supply roller 5 so that a great number of microfields are formed. The microfields allow only charged developer to form multiple layers on the surface of roller 4. Consequently, only charged developer with a minimum of uncharged toner is transferred to image carrier 1. <IMAGE>

Title: Plotter with ink pressurizing pump.
Inventor: GERBER HEINZ JOSEPH
IPC: F04B53/12
Filed: 1993-07-06
Abstract: A pen plotter (10) includes a pump (44) for applying pressurized air to the ink reservoir supplying the pen mechanism (32) with ink. A pressure switch (132) communicating with the pressurized air space provides an out-of-ink signal when the reservoir and pen become empty and the air pressure becomes lost due to air leakage through the pen. The plotter uses a web of paper (18) which is intermittently advanced to bring fresh portions of the web to a support surface (14) cooperating with the pen. The pump (44) is driven by the motor (42) which advances the paper so that the pump is operated only during paper advancements. <IMAGE>

Title: Coupling assembly preventing incorrect installation
Inventor: VOSS WILLIAM J
IPC: F16L23/036
Filed: 1993-12-08
Abstract: A coupling assembly, e.g. for flanged ducts, includes a first coupling element having first and second ends and a second coupling element having first and second ends. A first structure secures the first end of the first coupling element to the first end of the second coupling element. A second structure secures the second end of the first coupling element to the second end of the second coupling element. The second structure includes a latch 162 pivotally and slidably mounted on the second end 118 of the first coupling element and an eyebolt 174 pivotally secured to the first coupling element second end 118. A nut is selectively threadable onto a threaded end 190 of the eyebolt. A construction is provided which prevents an incorrect installation of the second end 128 of the second coupling element in relation to the latch 162. The construction can take several forms including a reduced width slot 184 on the latch, an interrupted slot (208, 210, Fig. 6, not shown) on the latch or tabs (230, 232, Fig 7, not shown; 248, Fig. 8, not shown) extending inwardly from at least one of the legs of the latch toward the other leg. In conjunction with a suitably sized eyebolt, these constructions prevent enough travel of the latch 162 as to allow for an incorrect fastening in which the second end 128 of the second coupling element is positioned around the eyebolt but outside the latch when the nut is threaded onto the eyebolt. <IMAGE>

Title: Methanol purification
Inventor: KENNY GERARD
IPC: C07C29/80
Filed: 1994-06-07
Abstract: Feedstock Methanol containing impurities such as Acetone, Methyl Ethyl Ketone, Water, Formic Acid, Formaldehyde, Acetic Acid and Methyl Esters is purified by adding the feedstock together with a reducing agent such as lithium aluminium hydride to the reflux vessel of a batch distillation unit. The mixture is heated for at least half an hour at a temperature of at least 65 DEG C. A strong base such as potassium hydroxide is then added and the mixture is heated to reflux. The optional final stage in the purification process involves adding a weak base such as sodium carbonate and heating the mixture under reflux. A very high level of purity of at least 99.9% is obtained.
