Abstract: A B S T R A C T           A collapsible dispensing tube in which plastic fabricating materials other than conventional materials can be selected which are more suitable, since the pressure in the process is increased while the temperature is decreased.          This manufacturing method utilizes a locking taper resulting in a better bond between the headpiece, barrier member and the inner wall of the collapsible tube and substantially eliminating blow-by of plastic material into said collapsible tube.  The barrier member has an extreme peripheral edge at least a substantial part of which is tightly engaged with the adjacent inner wall of the collapsible tube and substan-tially eliminates bypass of gases around the barrier member.          The method of manufacture permits the selection of the most suitable thermoplastic material for the intended use from a group of materials.

Abstract: ABSTRACT               The present invention is directed generally to an elec-trical connector including a contact for forming a crimped, insula-tion-piercing electrical connection.  Prior art insulation-piercing type connectors have proven unacceptable when used with stranded wire core conductors, because tensile forces applied to the conductors, as well as the cold flow of the insulation sur-rounding the core, causes the individual strands of the wire core to move and reposition within the insulation-piercing contacts causing changes in contact resistance.  The present invention overcomes these deficiencies of the prior art by providing an improved connector including a dielectric insert, a plurality of electrical contacts and means providing access to the contacts for effecting the crimped, insulation-piercing termination.  The contacts each include a terminal portion with opposed sidewalls mounted within a cavity of the insert, and the access means com-prises a passageway in the insert which accommodates a crimp tool used to deform the sidewalls of the contact terminal and secure the conductors in termination position within the contacts.

Abstract: ABSTRACT      In a hydrostatic support member with at least one pressure pocket in the head portion of the support member, the or each pressure pocket opening opposite a surface which is to be supported, the inner side of the lining wall which defines the pressure pocket relative to the environ ment of the support member        is inclined relative to the pressure axis of the support member, so that the profile of the pressure pocket becomes larger towards its base.  The outside of the lining wall extends relative to the inner side in such a way that when this wall is lowered towards the base the hydrostatically effective surface of the head portion, facing the surface which is to be supported, increases in size. A method of producing or finishing the support member according to the invention is proposed:  The support member is first prefabricated with the head portion having a relatively small hydrostatically effective surface, compared with an operational one, the walls having been made higher.  It is then used under conditions which simulate actual operation.  The prefabric-ated walls of the at least one pressure pocket being so lowered by a lapping type process.  As the hydrostatically effective surface of the head portion increases in size during this lowering, the lapping stops automatically at the stage when the optimum operational hydrostatically effective surface for the head portion has been obtained.

Abstract: ABSTRACT     A pumping unit primarily for dispensing liquid detergent into the tank of a dishwashing machine comprises a bellows pump of which the bellows define a detergent-receiving chamber communicating with a detergent supply passage and a detergent delivery passage. Each said passage is associated with a non-return value.  The bellows are biased to an expanded condition and draw detergent into the additive-receiving chamber on the expansion stroke.  Upon collapse of the bellows by means of pressure-responsive and weaker second bellows, detergent is ejected through said delivery passage.  The second bellows are in communication with a source of main liquid flow under pressure.

Abstract: ABSTRACT OF THE DISCLOSURE          Hydrogen is produced by immersing a piece of magnesium in an electrolytic solution containing, for example, nickel, chromium, manganese, iron or platinum and then by immersing the magnesium piece in a neutral salt solution containing, for example, NaCl or KCl, or in sea water.  Furthermore, hydrogen is produced by keeping a magnesium piece in contact with a metal, such as iron in the neutral salt solution for a certain period of time and then by replacing the magnesium piece in another neutral salt solution.  In the latter method, the generation of hydrogen can be accelerated by connecting the magnesium piece and the metal to a direct-current supply in the range of 5 V to 200 V for a short time before the magnesium piece is immersed in the second neutral salt solution.

Abstract: ABSTRACT OF THE DISCLOSURE        A refrigerator container for food.  The container includ-es a receptacle portion comprising a plastic which is resistant to flexing and a lid for sealing the container.  The lid has an in-flexible portion which comprises a material having the same shrink properties as the receptacle and a resilient portion, the inflexi-ble portion including a peripheral flange which extends parallel to the inner surface of the mouth of the receptacle portion, the outer surface of the peripheral flange being substantially the size of but slightly smaller than the inner surface of the mouth of the receptacle portion.  The resilient portion of the lid in-cludes a peripheral flange that fits about and closely adjacent the outer surface of the peripheral flange of the inflexible por-tions so that when the lid is used to close the container there is a tight fit between the lid and the mouth of the receptacle as the flange of the inflexible portion is urged against the flange of the resilient portion.  The inflexible portion of the lid has the same shrink characteristics as the receptacle portion so that a tight fit between the lid and the receptacle at room temperature remains tight when the container is placed in a refrigerator.
