Title: Protective plastics coatings for pipes
Inventor: HIELEMA RALPH
IPC: F16L58/16
Filed: 1971-10-01
Abstract: Protective coatings are formed on pipes by (a) progressively unwinding a strip of plastic material coated with a corrosion resistant adhesive on its external surface with a marginal overlap onto the pipe, (b) applying a film which provides protection against mechanical effects under unwinding tension to the coated pipe with predetermined overlap, and (c) applying a molten thermoplastic adhesive to the marginal portion of the back of the film. The marginal portion has a greater width than the overlap of the protective film, and the overlapping tension leads the thermoplastic adhesive into intimate contact with the surface of the black edge of the film and the adjacent front edge of the film, and with the adjacent portion of the strip to form a bond. The first layer of plastic strip protects the pipe against corrosion, and the second layer of film protects the plastic strip against mechanical damage.

Title: Uric acid determination - using uricase and catalase
Inventor: HAURY HEINZ DIPL CHEM DR RER N
IPC: C12Q1/62
Filed: 1972-05-20
Abstract: Uric acid is determined in body fluids (esp. serum, spinal fluid and urine) by means of uricase and catalase with conversion of the formaldehyde formed into 3,5-diacetyl-1,4-dihydrolutidine with acetylacetone and ammonia, the uric acid content of the unknown soln. being calculated from the kinetics of the course of the reaction by comparison with a known standard. The use of a kinetic method for determining the uric acid concn. renders the determination substantially simpler more rapid and more exact, since over a certain range there is a direct linear relationship between the rate of colour formation and the concn. of uric acid.

Inventor: SCHMIDT REINHOLD DIPL ING
IPC: F04C15/00
Filed: 1973-12-27
Abstract: Rotor or housing of axially adjacent discs for screw rotary engines with units for operation at high temps. has the discs tapered, in dependence on their coefficients of expansion and a measured or calculated isothermal field from the region of the coolant openings to their periphery, in thickness, and pref. slotted at 90 deg. to the field of isotherms, such that at max. working temp. the taper and slot opening are exactly compensated.

Title: Connectors for solid conductors within conductor profile - and allowing ready disconnection of the joined conductors
Inventor: HOOGEVEEN FRANK
IPC: H01R4/50
Filed: 1974-03-27
Abstract: Connectors of this type find application in specialised equipment, for example in the helical coils associated with nuclear fusion apparatus, where conventional joints cannot be made due to lack of space, high temperature, or other considerations. The conductors are joined by material of high conductivity, normally higher than that of the conductors, whose profile is no greater than that of the conductors. For example two circular copper wires may be joined by a silver wire of smaller diameter. The copper wires are bored out and shrunk onto the silver wire. The contact faces may be gold plated to reduce the contact resistance.
