Title: Improvements in or relating to underwater vehicles
Inventor: HAMPSON DOUGLAS JAMES
IPC: B63C11/42
Filed: 1984-07-02
Abstract: An underwater vehicle for pipeline and route survey work which is adapted to be towed submersed on a general heading, for example by a surface vessel. In order to provide positional control of the vehicle it is provided with thrusters (31, 33, 35) and rotors (43, 45, 47) acting in combination. The rotors are in the form of elongate cylindrical members. Depth and lateral control is provided by three thrusters, two horizontal pairs of rotors and one vertical rotor. A thruster is associated with at least one rotor. The thruster provides the necessary flow for the rotors to create sufficient vector force for accurate positional control even at low speeds. <IMAGE>

Title: Moulding apparatus
Inventor: FENWICK RICHARD GEOFFREY
IPC: B28B13/02
Filed: 1984-07-18
Abstract: A moulding apparatus includes a mould box (10) having a pair of formers (12) in cavities (14) defining annular mould spaces. The formers are retained by support members (16), and a feed box (24) for delivery of material to the mould spaces has gaps (28) in a front side (26) to enable movement past the members (16). When the feed box is retracted from the mould spaces, tamping devices (22) are lowered into the spaces, the mould box is raised and then the devices are raised to allow formed articles to be removed. After subsequent lowering of the mould box and prior to the feed box returning, a scraper plough (30) is moved over the upper surface of the mould box to push unused material back into the mould spaces for re-use. Alternatively the unused material may be removed by a chute and transferred back to the feed box. <IMAGE>

Title: Dispensers
Inventor: DROBISH JAMES LEE
IPC: B65D83/76
Filed: 1984-10-26
Abstract: A dispenser includes an axially extending tubular body 51 for housing a product to be dispensed and having an upper end from which the product is dispensed through a nozzle 31 by applying pressure to resilient top 21. A follower piston 70 is slidably mounted within the lower end of the body 51 to support the product thereabove. The piston is constructed of resilient material and comprises a face portion 76 adapted to contact the product and a peripherally attached sidewall. The sidewall comprises at least one integral peripheral contact band conforming to the shape of the cross section of the bore, and is adapted to virtually resiliently extend or contract in response to axial forces exerted on the face portion with such change in length resulting in an inversely proportional virtual change in lateral dimension of the peripheral contact band. The peripheral contact band is dimensioned to provide an interference fit within the bore and exerts a predetermined normal force against the inner surfaces of the bore in static condition. <IMAGE>

Patent GB-2157675-A (GB)
Title: Glass containing radioactive nuclear waste
Inventor: BOATNER LYNN ALLEN
IPC: C03C3/16
Filed: 1985-04-01
Abstract: Lead-iron phosphate glasses containing a high level of Fe2O3 for use as a storage medium for high-level radioactive nuclear waste. By combining lead-iron phosphate glass with various types of simulated high-level nuclear waste, a highly corrosion resistant, homogeneous, easily processed glass can be formed. For corroding solutions at 90 DEG C., with solution pH values in the range between 5 and 9, the corrosion rate of the lead-iron phosphate nuclear waste glass is at least 10<2> to 10<3> times lower than the corrosion rate of a comparable borosilicate nuclear waste glass. The presence of Fe2O2 in forming the lead-iron phosphate glass is critical. Lead-iron phosphate nuclear waste glass can be prepared at temperatures as low as 800 DEG C., since they exhibit very low melt viscosities in the 800 to 1050 DEG C. temperature range. These waste-loaded glasses do not readily devitrify at temperatures as high as 550 DEG C. and are not adversely affected by large doses of gamma radiation in H2O at 135 DEG C. The lead-iron phosphate waste glasses can be prepared with minimal modification of the technology developed for processing borosilicate glass nuclear wasteforms.

Title: Shoe having a midsole of polyurethane and a walking sole of elastomer
Inventor: GRAF DR HANS-JOACHIM
IPC: A43B13/12
Filed: 1986-12-15
Abstract: A shoe has an injection-moulded midsole 6' of polyurethane and an injection-moulded walking sole of elastomer 16'. The midsole and walking sole are connected by chemical bonds between the isocyanate of the polyurethane and reactive terminal groups of substances added to the elastomer. In order to make the shoe, a catalyst is added to the polyol and isocyanate mixture which reacts to form polyurethane to influence the speed of reaction and substances having reactive terminal groups are added to the elastomer. The walking sole is formed and the mixture for the midsole is introduced into a space between the walking sole and an upper. The reaction speed of the mixture and the temperature of the elastomer are controlled so that the chemical bonds are formed. An apparatus for making the shoe has separate appliances for moulding the walking sole and the midsole. <IMAGE>
