  • Patent number: 4574020
    Abstract: Apparatus and methods are disclosed for a high speed production line in which a container is wrapped with a plastic label comprising a foam polystyrene layer, there being means to move a leading edge of the label to the periphery of a rotating vacuum drum, means to apply methylene chloride to the underside of the foam layer to form finite areas on the leading label edge and a finite area on the trailing edge. The finite areas have therein a rapidly solidifying tacky solution of the foam polymer in methylene chloride, the tacky viscous solutions rapidly solidifying to form an adhesive bond. The solvent-applied label is quickly moved to a label wrapping station where it is wrapped around a container, the finite areas on the leading edge tacking the label to the container, and the finite area on the trailing edge forming a cohesive bond on the seam formed by the overlapped label ends.

  • Patent number: 4571366
    Abstract: A process for forming a doped oxide film and a doped semiconductor suitable for electronic applications wherein a silicon tetraalkoxide is reacted with a limited amount of water to produce a low molecular weight, soluble polyorganosiloxane. The polyorganosiloxane is subsequently admixed with a soluble dopant element compound to form a homogeneous, polyorganosiloxane-dopant compound solution. The solution is coated onto a semiconductor wafer substrate material and heated to produce an impurity doped semiconductor wafer suitable for electronic application.

  • Patent number: 4567681
    Abstract: The present invention provides, without the drawbacks accompanied by the use of hot melt adhesives, an attractive, easily recycled labelled container, the label, on its underside that is adjacent the container when applied, being provided with a finite area on its leading edge and a finite area on its trailing edge, by applying thereto a solvent for the polymer in each of the finite areas, the finite areas comprising a viscous tacky solution of the polymer in the solvent, the solidifying solution being sufficient to tack and bond the label to container during wrapping.After the label is wrapped around the container, the bond between the container and label becomes weaker as the solidifying solution hardens so that later the label can be easily and cleanly stripped from the container for recycling.

  • Patent number: 4555296
    Abstract: A universal hot air nozzle and seal bar with adjustable cam for use on an apparatus for forming and assembling tubular thermoplastic sleeves. The apparatus has a circumferentially movable turret with a plurality of mandrels forming work stations thereon. At the work stations each mandrel has a nozzle and seal bar and the sleeve is wrapped around the coacting mandrel with the vertical edges of the sleeve being disposed in overlapping relation with heat being applied by a stationary heat nozzle to the overlapped edges in coaction with a stationary seal bar being subsequently advanced to the heated overlapped edges with preselected pressure to heat-seal such edges together. The improvement includes cam-actuated telescoping mounting means in the form of a slidable telescoping shaft within a slidable telescoping shaft upon which the seal bar is mounted enabling the seal bar to selectively contact the sleeve with preselected pressure.

  • Patent number: 4548637
    Abstract: A servo control system and method for controlling repetitious or oscillatory motion of a member in a glass manufacturing process between predetermined points. A desired trajectory between such points is first established as a function of time, and this trajectory is then loaded into a digital electronic memory as a plurality of discrete trajectory position signals arranged in an incremental series as a function of time. Control logic, which includes a real time oscillator, periodically accesses the memory so as to sequentially select and read therefrom the incremental trajectory position signals. These incremental signals are fed as a desired position control signal to a servo amplifier, which receives a second input from a position transducer coupled to the movable member and provides an amplifier output to a servo motor and then to the member.

  • Patent number: 4539232
    Abstract: A method for producing solventless liquid organopolysiloxanes is disclosed. The method involves hydrolyzing an organo silicon composition comprising at least one compound having the general formulaY.sub.(4-n) Si(OR).sub.nwhere Y is phenyl or a primary or secondary alkyl group having from one to four carbon atoms, R is an alkyl group having from one to three carbon atoms, and n is an integer from one to four, and wherein the ratio of OR groups to silicon atoms in the composition is from 2.3:1 to 3.1:1. The products of hydrolysis are then heated to cause substantial siloxane formation by condensation and to distill water and alcohol by-products. Heating is continued until the water content of the resulting siloxane composition is less than 1 percent. The purity of the organo silicon composition, the amount of water used for hydrolysis, the amount of acid present during hydrolysis, and the heating of the organopolysiloxane are so controlled that the solventless organopolysiloxane has a viscosity at 25.degree. C.
