Abstract: The invention relates to a gripping device for removing moulded parts (1), for example low density foam parts, from a mould (20). The gripping device comprises a gripping cup (24), formed as a shell moulding, the interior of which corresponds in shape with the upper half of the moulded part so that it can fit around at least a peripheral part of the upper portion. The upper portion of the cup (24) contains at least one vacuum chamber which is connected by a vacuum inlet (11) to a vacuum source. Means may be provided for supplying compressed air to the interior of the inner portion (9) at the same time as vacuum is applied to the vacuum chamber (10), to remove the part from the mould (20). The invention also includes a method of making the gripping device, and a method of removing a part from a mould.

Abstract: A vapor recovery nozzle, employed in minimizing atmospheric pollution by fuel vapors is described. The nozzle comprises a bellows (48) which is compressed against the fill pipe of a vehicle fuel tank during discharge of fuel therein. The bellows surrounds a nozzle spout (34) to define a vapor return flow path (52) which extends through a nozzle body. The body of the nozzle is compositely formed by a body member (32) and a vapor path cap (54) which compositely define the vapor return flow passage. Flow of fuel is controlled by a control valve (38) which may be opened, or maintained opened, by an operating lever (40) only when a trip mechanism stem (42) is latched in an operative position. A mechanical interlock (44) prevents latching of the trip mechanism stem unless the bellows is compressed in sealing engagement with a fill pipe. When the bellows is so compressed, the trip stem is latched. If the level of fuel in the fill pipe covers the end of the spout, vacuum actuated means unlatch the trip mechanism stem. If the pressure in the vapor return flow path rises to a level indicating a blockage in return flow, the trip stem is also unlatched. A vapor valve is provided in the bellows to prevent the escape of fuel vapors when the nozzle is in a rest position. Angular relationships of the bellows and the spout facilitate obtaining a seal with a fill pipe. A groove is formed in the spout outwardly of and adjacent the vapor seal so that the vapor seal maintains its integrity in the event the spout is broken when inserted in a fill pipe. A trip mechanism sub-assembly, a spout sub-assembly and a bellows sub-assembly facilitate rebuilding, as well as the original assembly, of the nozzle.

Abstract: Improved zero-current switching forward converter circuits are described. A power transformer including a primary and a secondary winding is constructed to have an effective secondary leakage inductance L2e. A first switching device selectively couples a power source across the primary winding of the transformer. A first unidirectional conducting device connected in series with the secondary winding is oriented to conduct during conduction by the first switching device. A capacitor of capacitance C is connected in series with the secondary winding and the first unidirectional conducting device. The first switching device is controlled to selectively close and open transfer power from the voltage source via the effective leakage inductance of the transformer to charge the capacitor during an energy transfer cycle having a characteristic time scale of π √ L2e*C.  A second switching device is connected on the secondary side of said transformer and is controlled to open and close to selectively govern the amount of energy transferred during the energy transfer cycle.

Abstract: In a tap cock, designed to be of composite construction, the cock housing consists of an outer housing (1) of a material of relatively high mechanical strength and of a ceramic cladding (2 to 4), which is held in the outer housing (1) and is supported on the outer housing (1). The cock tap (11), like the cladding (2 to 4) of the tap cock, is produced from ceramic. The cladding (2 to 4) of the cock housing consists of a tap pipe (2), in which the cock tap (11) is rotatably supported, and of connecting pipes (3, 4), which connect the connections (12, 13) of the tap cock to the tap pipe (2). On the one end side, the connecting pipes (3, 4) have a recess (14, 15), which is matched to the cylindrical curvature of the outer surface of the tap pipe (2). The tap pipe (2) is secured against rotation by at least one ceramic bolt (5, 6) which extends from the cock housing into the wall of the tap pipe (2). The tap cock is of simple construction and permits optimisation of the cladding of the cock housing for operation during sudden temperature changes.

In the present programming device, an allocation table representing a relation between respective PCs and devices controlled by the respective PCs is entered. In the first program for the first PC, an external input element belonging to the second PC is described with an identifier. The external input element is extracted from the first program and I/O element corresponding to the external input element is designated as a referred-to I/O element in the second program. The referred-to I/O element is related to a link element assigned to a link address which can be commonly accessed by the first and second PCs. An instruction step for making status data of the link element equal to status data of the referred-to I/O element is added to the second program. In the first program, the identifier of the external element is converted into the link address assigned to the link element. Thus, programs enabling an interlock control among a plurality of PCs are automatically created.
