Abstract: ABSTRACT         A thermal switch having an improved contact mechanism which is cheap and easy to manufacture, in which a conductive casing is provided with a terminal connected to the casing and a terminal insulated therefrom.          A resilient contact means within the casing is compressed in the axial direction between a solid fusible pellet and the insulated terminal with which it is in electrical contact, so that it is normally expanded radially outwardly to electrically contact the casing.  At a preselected melting temperature the pellet collapses to release the axial pressure on the resilient contact means and thus permit its radial contraction out of electrical contact with the casing.

Abstract: Abstract In the production of nuclear fuel pellets consisting essentially of oxides of uranium or mixtures of these oxides with oxides of thorium or plutonium by granulating the oxide powder, pressing the granulated powder into compacts and sintering the compacts, niobium pentoxide is added to the oxide powder in sufficient quantity to encourage grain growth in the oxide compact during sintering and the sintering and other process parameters are adjusted so that no impurities are trapped in the sintering pellets which would prevent a high matrix density and grain size being obtained.      Adjustment and control of the oxygen potential of the sintering atmosphere is proposed.

Abstract: Abstract of the Disclosure A novel "cast-on" method and apparatus are dis-closed wherein in the preferred embodiment only one major moving part is provided which is indexed through various positions to cast a group or element from a battery plate stack engaged thereby.  In the preferred embodiment, a mold carriage block having a plurality of molds voids formed therethrough slidingly reciprocates along a base plate on which are defined fluxing (loading), casting and part-release positions.  In the casting position, lead gravitationally siphons into the mold voids defined in the mold carriage through molten lead supply orifices defined in the base plate along which the carriage slides.  Once the casting operation is completed, sliding the carriage out of the casting position effectively seals the molten lead supply orifices.  The apparatus and method are particularly suited for use by a single operator who manual-ly loads stacks into the apparatus and subsequently unloads completed groups or elements from the apparatus.

Abstract: A B S T R A C T         In an apparatus for casting metal between a pair of heat-conductive belts an array of closely spaced hexagonal-headed support members are arranged behind each belt at the mould space. Each support member includes a restricted axial coolant jet passage and a film of coolant is maintaining between each head and the adjacent belt, which is pulled against the support heads by maintaining subatmospheric pressure conditions in the region of the supports.  Each support member is slidably mounted in a base and is forced towards the belt by a spring but a stop retains each support when the belt is removed.  The close spacing of the hexagonal heads prevent their rotation in relation to each other but an individual support can be released by depressing the support head out of the plane of adjacent support heads and rotating the support through 60° to disengage it from its stop. The support can then be withdrawn axially.

Abstract: APPARATUS FOR AND METHODS OF    IDENTIFYING HORSES BY SCANNING THEIR CHESTNUTS            Abstract of the Disclosure The identity of horses is established by optically scanning the four "chestnuts" located on the insides of their legs to generate digital numbers corresponding to the width, height and area of each chestnut.  These numbers are encoded digitally with an application number assigned to the individual horse and the serial number of the equipment performing the scan to produce a code which is then stored on tape within a tape recorder.  The code is thereafter transmitted to a central data bank for future reference so that the identity of the horse can be subsequently checked to prevent fraudulent and mistaken substitution of horses.  The apparatus and method is also useful in identifying lost horses and in controlling theft and disease.
