Patent number: 4026751Abstract: A probe cover incorporating an inner sheath with a probe end engagement section. The section comprises a reduced width of the inner sheath adjacent the end opposite that into which the temperature probe is inserted. The reduced width section is produced by bonding of the layers of the sheath together with a graduated bond strength so that with a combination of bond separation and material stretch good contact and retention of the probe end is insured. A tapered welding head in association with a resilient platen is utilized to obtain the graduated weld section. When the temperature probe is removed after use the inner sheath is turned inside-out so that the contamination of the inner sheath is contained inside the inverted sheath and cannot contact the users hands.Type: GrantFiled: February 23, 1976Date of Patent: May 31, 1977Inventors: Charles F.

Patent number: 4025385Abstract: A label applicator has a rotating head assembly for carrying labels from a hopper for application to articles to be labelled. The labels are held on the head assembly by suction. To load labels from the hopper, the hopper is reciprocated towards a spring loaded suction head of the head assembly, depressing the head thereby connecting suction to it, and then away again. A latch locks the head in a depressed state so that a label is withdrawn from the hopper. The head assembly is driven stepwise to stop temporarily for loading a label on each head. The latch is released allowing the loaded head to spring forward when it has rotated to a desired orientation on the head assembly. The released head presses the label onto the article to be labelled simultaneously disconnecting the suction. For heat activated adhesive labels, a radiant heater, preferably a quartz infra-red tube, is arranged to irradiate labels when loaded on the suction heads.Type: GrantFiled: November 5, 1975Date of Patent: May 24, 1977Assignee: Green Shield Trading Stamp Company LimitedInventor: William Wood

Patent number: 4025379Abstract: An extrusion billet is fabricated from layers of soft magnetic material separated by one or more metal layers. The billet is coreduced and heat treated to impart the desired magnetic properties to the soft magnetic material and also to form intermetallic insulating layers between the magnetic layers. Electric field shield sections are formed in a similar manner by placing relatively thick layers of copper between adjacent layers of metal located adjacent to the layers of soft magnetic material. The layers of soft magnetic metal can also be separated by a layer of semiconductor material; or a metal foil having a semiconductor-forming or high electrical resistivity forming material deposited thereon. In the latter case no extrusion is required. Instead, pressure and heat cause the materials to react and form either a semiconductor layer or a layer with an electrical resistivity higher than about 10.sup..sup.-4 ohm-cm between adjacent layers of soft magnetic metal.Type: GrantFiled: February 18, 1975Date of Patent: May 24, 1977Inventor: Clayton N.

Patent number: 4025375Abstract: A method and apparatus for continuous welding together of sheets of the type in which adhesion is derived from the melting and re-hardening of the sheet material itself rather than from an externally applied adhesive. A sheet, formed into a tube with the opposite sides overlapping, is tensioned longitudinally so as to form longitudinally extending stress lines which appear as ripples, at least at the overlapping edges such that the sheets weld at the bottom of the valleys formed by the ripples. As the tensioned sheet moves continuously between a heating element and a backing plate, both of which are stationary relative to the tube forming means, the sheets weld as the material from the sides of the valley of at least one sheet runs to the bottom of the valley, at which point the weld bead is formed, whereby the thickness of the weld bead may be more than twice the thickness of the original unheated sheet material.Type: GrantFiled: May 23, 1972Date of Patent: May 24, 1977Assignee: Mira-Pak, Inc.Inventor: William C.
