Patent ZA-857303-B (ZA)
Title: Closure device for a container
Inventor: ROSENTHAL KARL-HEINZ
IPC: B65D47/26
Filed: 1985-09-23
Abstract: A closure device for a container is described consisting of a cap for a container and a cap lid which is pivotably mounted on the cap. The cap lid has an encircling circumferential border which projects downwardly from the upper surface of the lid. The border is a curved spherical surface segment and the cap defines a cup-shaped recess which is complementary in shape to facilitate sealing. The center of curvature of the spherical surface segment is located on the pivot axis of the cap lid. A pair of supporting plates are formed on a base portion of the cap and are guided in the pivot plane of the cap lid by parallel guide ribs so that the cap is non-rotatably mounted and pivotably mounted reliably in the recess and is sealed in every operating position relative to the container cap.

Title: Process for preparing multilayer printed circuit boards
IPC: H05K1/00
Filed: 1987-09-17
Abstract: Multilayer printed circuit boards are fabricated by preparing a first layer in conventional manner by forming a resist image on a copper clad substrate, etching away unwanted copper, removing the resist from the circuit pattern and optionally applying a dielectric mask such as conventional solder mask to selected portions of the circuit pattern. A second layer, and optionally one or more subsequent layers, are fabricated by providing an image of a second circuit pattern in a predetermined location on said first layer, the image being formed using a suspension of cuprous oxide in a curable resin material. The image is cured at least partially and subjected to chemical reduction to convert at least a portion of the cuprous oxide to metallic copper such that the unreduced cuprous oxide in resin serves as a dielectric layer. The image is then electrolessly plated with copper to build up the circuit pattern and the latter is selectively coated with a dielectric mask before repeating the cycle to build up one or more additional layers. Solder can be applied to selected areas of any of said printed circuit layers at any appropriate time during fabrication. The above method of fabrication has advantages of economy of time, materials and labor as compared with methods hitherto employed to prepare multilayer boards in which a plurality of single boards are fabricated individually and then assembled as a sandwich or laminate by application of heat and pressure.
Patent ZA-879285-B (ZA)
Title: A composition comprising a polyeposide and an epoxy fusion catalyst,and a process for preparing fused epoxy resins
Inventor: JACKSON ROY JOSEPH
IPC: C08G59/42
Filed: 1987-12-10
Abstract: According to the application, a relatively low molecular weight epoxy resin is reacted with an acidic fusion compound in the presence of a bis(trihydrocarbylphosphine)iminium salt catalyst to produce a high molecular weight fused epoxy resin. The process is particularly useful in reacting an epoxy resin having a molecular weight of less than 500 with 2,2-bis(4-hydroxyphenyl)propane in the presence of a bis(trihydrocarbylphosphine)iminium halide to produce a fused epoxy resin having a molecular weight within the range of 500 to 7000. The catalyst is relatively water-insensitive, and the reaction can therefore be carried out in the presence of water.

Title: Electronic thermometer
Inventor: YOSHIZAWA MASAYUKI
IPC: H03M1/00
Filed: 1985-01-23
Granted: 1987-10-07
Abstract: An electronic thermometer is provided in which the number of pulses counted in a first count and the number of pulses counted in a second count are respectively proportional to the resistance of a reference resistance and that of a thermosensing element. When the first counted value is to be adjusted so as to realize the absolute value adjustment of the thermometer, the difference between the resistance of the thermosensing element and the resistance of the reference resistor is adjusted by varying the number of counts in a counter upon whose content the timing of the second count depends. Accordingly, the absolute value precision adjustment of the electronic thermometer is realized by providing an initial logic adjustment circuit in which the number of the first clock counts is appropriately varied.

Title: Test head for compressed gas cylinders
Inventor: GRENCI CARL A
IPC: G01N3/12
Filed: 1985-08-02
Granted: 1986-06-04
Abstract: A test head useful in the testing of compressed gas cylinders capable of withstanding high pressure. The water jacket head includes a neck seal including a spud insertable into the neck of a compressed gas cylinder for permitting a high pressure seal to be made to the cylinder. The present neck seal incorporates a permanent quick-connect sleeve for which mating male spud insert units can be designed for nearly any size cylinder neck. Changing the spud insert can be accomplished by hand, without removing the head from its use location. A diaphragm support spring is installed between the moving spud stem assembly and the top plate of the head which biases the spud stem assembly, thus increasing diaphragm life and preventing increasing reassembly difficulty following spud changes. Studs and screws replace welds in holding the top, side and bottom plates together which greatly alleviates the task of servicing inside the head when leaks eventually occur in the moving elements. A heavy, long-lasting, fluid pressure expansible head boot is included which requires less servicing, simplifying field installation.

Title: Inflation device
Inventor: PERRINS JOHN
IPC: F16K31/00
Filed: 1999-08-27
Granted: 2000-12-06
Abstract: An inflation device (5) for an inflatable article (such a life jacket), includes a housing (8) for holding a container of pressurised fluid (6), a displacement means (12) including a piercing means (15) displaceable so as to penetrate the container (6) and allow the release of said pressurised fluid, and actuation means (23, 27, 28, 29) having engaging co-operating elements (17, 25) which engage to retain the displacement means (12) in an unactuated configuration. The actuation means (23, 27, 28, 29) release the displacement means (12) both through the presence of water or by manual operation. The co-operating elements (17, 25) are substantially radially arranged. The line along which the displacement means (12) acts may be coaxial with the radii of the co-operating elements (17, 25). One of the co-operating elements (17) is capable of inward radial movement, and the actuation means (27, 28, 29) operates to prevent that co-operating element's (17) radially inward movement. Similarly, one of the co-operating elements (25) is capable of outward radial movement, and also prevented by the actuating means (23). When the actuation moms (23, 27, 28, 29) is triggered (by water or by the manual release), the movement of one of the co-operating elements (17, 25) causes the displacement means (12, 15) to pierce the container.
