Abstract:
The present invention relates to a device for transporting and storing of a powder or liquid medium, comprising (a) a structurally stable outer container having an electrically conducting inner surface, a top side that is open and capable of receiving an inner container, and a bottom section comprising a plurality of recesses wherein each recess can receive a pronged platform of a cargo moving device; and (b) an inner container capable of holding said medium having a top section, an opening in said top section for filing and discharging said medium, and one or more walls. These walls are made of a plastic material, are adjacent to said inner surface of said outer container, and have an outer surface. The outer surface has at least one electrically conductive layer that is in electrical contact with the outer container's inner surface. Moreover, invention could optionally include a plastic pallet having an electrically conductive layer that is in contact with the outer container.
Abstract:
In the discontinuous manufacture of multilayer, co-extruded, hose-like thermoplastics material preforms used in the production of large volume multilayer hollow members in a divided blow mold, at least two different annular shaped material melts are brought together in series within an axially extending annular piston to form a multilayer material melt. An annular flow channel in the piston receives the layers of material melt. The flow channel widens in a funnel-like manner toward an annular storage space. The preform is subsequently ejected from the storage space through an annular nozzle gap by the annular piston moving in its axial direction. The annular piston acts as a co-extrusion head and is pressed upward by the multilayer material melts. In supplying the material melts from extruders into the flow channel of the piston, the material melts flow first in the extrusion direction and then are redirected for flow radially inwardly into the flow channel of the piston. By the redirection of the material melts in the transition from the extruder to the co-extruder or piston, no cross-sectional changes occur and weak points are eliminated or reduced to a point where they have no deleterious effect.
Abstract:
A control system for the stroke limitation of a machine tool element in which the element is connected with the slider of a potentiometer so that the voltage on the potentiometer slider varies in a respective direction with each direction of movement of the tool element. A pair of adjustable resistors are provided which form voltage sources with voltages conforming substantially to that of the potentiometer slider at the desired points of reversal of the tool element. The slider voltage is compared with the voltage at the adjustable resistors and the tool element is reversed when the slider voltage bears a predetermined relation to the voltage with which it is compared. A selectively adjustable delay could also be provided to delay the reversing of the tool element at at least one of the limits of travel thereof.

Abstract:
The invention relates to a method and to a device for producing a boat-type body (10) of a water sport device. According to the invention, a rotating frame (12), which is pre-formed about an access opening of the boat-like body (10), is arranged on an inner side of a negative mould. The outer shape of the boat-type body (10) is predetermined, essentially, by the innerside of the negative mould. The boat-like body (10) is produced in the inner side of the mould by means of a thermoplastic shaping method. During the shaping process, at least one part of the surface of the rotating frame (12) is in contact with the boat-like body (10) which is formed by the thermoplastic shaping method. The invention also relates to a water sport device.
Abstract:
The invention relates to a device for the production of multi-layer, co-extruded, tubular pre-forms made from thermoplastic plastic. A co-extrusion head (10) comprises co-axially arranged flow channels (FK1, FK2), each supplied by a single inlet opening (ZF1, ZF2) with a material melt, distributed annularly in a distribution ring (26, 28). The gap width in each distribution ring (26, 28) is greater in the vicinity of the inlet opening (ZF1, ZF2) than the gap width (s2, s6) in the region of the side opposing the inlet opening (ZF1, ZF2). The flow channels (FK1, FK2) are also asymmetric with regard to the gap widths.
Abstract:
The invention is directed to a quenching and contact arrangement for a compressed-gas circuit breaker. The arrangement includes a tubular contact piece and a contact piece axially arranged therewith. An arc is drawn between both contact pieces when the circuit is interrupted under load, the arc then being blasted by a stream of compressed-gas. A turbulence grid is arranged in the flow path of the stream. The turbulence grid is configured in the form of a tube of insulating material with perforations in the cylinder surface thereof which directly encloses the arcing space in the course of the circuit-breaking motion.
