Abstract: Zur Erhöhung des Wirkungsgrades eines Ozonerzeugers wird vorgeschlagen, dessen Aussenelektroden (1,2) im wesentlichen als paarig angeordnete, voneinander beabstandete Metallplatten auszubilden, zwischen denen ein Rohr (3) oder eine Lage dicht aneinanderliegender Rohre (3) mit einem dem Abstand der Metall platten entsprechenden Durchmesser liegen.Die Rohre (3} weisen eine äussere Schicht aus dielektrischem Material auf oder bestehen selbst aus einem solchen und besitzen je eine Innenelektrode (4) aus einem elektrisch leitenden Material. Trotz vergleichsweise inhomogenem Entladungsspalt (6) weist ein derartiger Ozonerzeuger einen hohen Ozonerzeugungswirkungsgrad auf, weil die im Entladungsraum entstehende Wärme optimal abgeführt werden kann.

Abstract: A piston (10) and piston rings (16, 17, 18) assembly. The piston rings (16, 17, 18) include a flat cylindrical face (20) and a support structure for supporting the face (20) such that under load the ring deflects so that the face (20) forms a hydrodynamic wedge between the face 20 and the cylinder wall. The support structure includes a pair of circumferential ligaments (22, 24, 34, 36, 45, 46) arranged relative to the face (20) of the ring so as to intersect at a point (25) in front of the face 25. The support structure may further include dog legs (37, 38, 47, 48). The face (20) may include scraping edges (42, 44). The piston ring may include an oil duct (50).

Abstract: A bag (210) comprised of flaccid material and having an improved integrally formed carrying handle which supports the weight of one or more articles (5) contained within the bag with minimal discomfort to the supporting portion or portions of the user's body. The bag includes an uppermost flap (55) containing the improved integrally formed carrying handle. The handle is provided by making a continuous curvilinear slit (282) in the flap, the ends of the slit comprising a pair of inwardly open arcs (285). The uppermost ends of the inwardly open arcs are inwardly extended until they transition into a centrally located, upwardly concave arc (295) which connects the two inwardly open arcs to one another. The material (298) adjacent the uppermost portion of the slit helps to provide a greater load bearing surface against the supporting portion or portions of the user's body, while the material (299) adjacent the lowermost portion of the slit forms a lowermost fold (297) helps to reinforce and stiffen the flap and thereby minimize lateral squeezing of the supporting portion or portions of the user's body whenever the bag is lifted or carried by the opening formed at the slit.

Abstract: A bistable electronically controlled pneumatically, powered transducer for use, for example, as a valve mechanism actuator in an internal combustion engine is disclosed. The transducer has a piston (1) which is coupled to an engine valve, for example. The piston is powered by a pneumatic source and is held in each of its extreme positions, and air control valves (3, 4) are held in their closed positions by pressurized air and/or permanent magnet latching arrangements (9, 50) and the control valves (3, 4) are released therefrom to supply air to the piston (1), and the piston is released therefrom to be pneumatically driven to the other extreme position by an electromagnetic neutralization (37, 60) of the permanent magnet field. The piston forms a part of the magnetic latching circuit and that magnetic circuit also includes a radially slotted ferromagnetic member (15) to both complete the magnetic circuit and provide a good air communication path from a high pressure air inlet (32) to the control valve. A pair of auxiliary pistons (51, 63) movable with the piston compress air to a pressure above the pressure of the pneumatic source for aiding reclosure of the control valves (3, 4) as well as aiding maintenance of those control valves in their closed positions thereby reducing the size and cost of the latching permanent magnets (9, 50).

Abstract: The device is intended to allow the passage of a fluid, which may be at a very different temperature from the ambient temperature, through an opening (2) made in a partition wall (1), while sealing the opening electrically. For this, the problems due to the temperature of the fluid are dealt with by using two coaxial conduits (3, 4) separated by a heat insulator (6) with the fluid flowing through the inner conduit (3). The electrical screening is obtained by a tight conducting partition (4, 5) extending from the inner conduit (3) to the edges of the opening (2). Application to enclosures of the Faraday cage type. <IMAGE>

Abstract: The supply quantities of water have the processing liquid which is jetted to the discharge machining zone and to the work bed (12) through upper and lower nozzles (15, 16) and a spray (35) communicating with conduits (32b - 32e) branched into two routes from a conduit (32a) connected to a tank (31) are regulated by a flow rate regulation valve (34). The two route supply quantities are inversely proportional to each other but their sum can be maintained. In rough machining, the jet quantity of water through the nozzle increases while the jet quantity through the spray decreases and at the time of shift from rough to finish machining where the jet quantity through the nozzle decreases but the jet quantity through the spray increases, the effective supply quantity of water to the work bed from both the nozzle and the spray does not change so that any thermal deformation does not occur.

Title: An earthing system
Inventor: CARTER DONALD STANLEY
IPC: B60R16/06
Filed: 1990-05-04
Abstract: An earthing system for earthing a vehicle (21) such as a liquid fuel tanker in a hazardous area such as a fuel loading or unloading area. The earthing system comprises a flying lead (13) for connection to an earth point (20) on the vehicle (21), a contactor (12) located in an explosion proof enclosure (16) for connecting the flying lead (13), and hence the vehicle (21), to earth, a monitoring line (5,26,27,29) passing along the flying lead (13) for connection to an earth point on the vehicle (21) and a proving circuit (10) for proving the integrity of the earth connection (4,22,23,29) between the flying lead (13) and the vehicle (21). The proving circuit (10) is arranged to actuate the contactor (12) to connect the earth line (4,22,23,29) of the flying lead (13) to earth only after its intended earth connection with the vehicle (21) has been proved satisfactory. The contacts of the contactor (12) through which the earth contact is made are located in the explosion proof enclosure and thus no spark is generated in the hazardous area on earthing. Preferably the current carried by the monitoring line (5,30) is of an intrinsically safe nature so that no spark is generated as the flying lead (13) is connected to the earthing point of the vehicle (21).

Title: Method of making high density solder bumps and a substrate socket for high density solder bumps.
Inventor: ALTMAN LEONARD F
IPC: A61K38/00
Filed: 1989-12-15
Abstract: A method of forming solder bumps includes the steps of applying a thick layer of solder resist (22) to a substrate (20). The resist is selectively removed to provide wells (23) at solder pads (21) on the substrate. The solder paste (24) is applied to the substrate in the wells. The solder paste is reflowed to form solder bumps (25) on the pads. A socket for a solder bumped member (36) is obtained by first providing a substrate (30) having metallized pads corresponding to the solder bumps of the member. A thick layer of photo definable solder resist (32) is applied to the substrate. The resist is selectively removed to provide wells (33) at the metallized pads (31) of the substrate. Solder paste (34) is then deposited in the wells. The solder bumped member (36) can then be positioned so that the solder bumps (37) are located in the wells. The solder paste (34) is reflowed to bond to the solder bumps (37) and the metallized pads (31). The solder paste (34) can be selected to have a lower melting temperature than the solder bumps (37). By reflowing the solder paste (34) at a temperature lower than the melting temperature of the solder bumps (37), the paste can wet to and blend with the solder bumps while not causing the solder bumps to reflow.
