Title: Pin type reactor fuel elements - tapered dia. wire helix maintains cooling space and allows for distortion
IPC: G21C3/338
Filed: 1973-02-19
Abstract: The neutron flux and hence fuel element can distortion which occurs during burn-up of a nuclear reactor fuel element is greatest at the centre of the reactor. Pin-type long elements, when pre-assembled into bundles, have a helix of spacing wire which has a smaller dia. at the middle of the element than at the ends. This increases the coolant gap around the elements and allows the middle of the element more room to distort or expand in dia, before the smaller dia. spacing wire makes contact with adjacent elements or with the coolant channel wall. This effective tapering of the wire can be achieved in many wasy e.g. by rolling with a taper or by placing a suitable pipe on the wire at its ends.

Title: Dispersive delay line - uses surface acoustic waves guided by a fluid
IPC: H03H9/44
Filed: 1973-03-30
Abstract: Between the parallel faces of two solid bodies is a stratified dispersive layer, by which mechanical coupling is affected. One of the bodies has a receiving transducer, the other a transmitting transducer. The acoustic impedance of each of the solid bodies and layer are sensibly equal. The fluid is a liquid body with low attenuation coefficient to sound waves. The first body has a sealed access for introduction of the liquid. In the direction of propagation, opposite faces of the second body are parallel, polished and covered with a metallic coating, and are perpendicular to the fluid interface substrate face. Soldered to each metallic layer is a transducer of transverse waves where direction of polarization is perpendicular to the substrate face. The transductors have an electrode located in the skin thickness of the wave generating surface.

Title: Board game requiring the building up of words - uses a grid and two sets of dice marked with consonants and vowels
IPC: A63F3/04
Filed: 1973-04-06
Abstract: A board game in which the player aims to build a maximum number of words, either horizontally or vertically, as in a crossword. Two sets of dice are used, vowels on one set and consonants on the other. The lines, or columns, of the crossword grid are marked by consonants in alphabetical order. At each throw, the value of the vowels and consonants selected are marked on the grid using a marker. When the game is completed, one point is counted for a vowel, two points for a consonant. The first player to reach a given total is the winner.

Title: Meat extrusion - with coextruded plastic casing
IPC: B29C48/06
Filed: 1973-04-13
Abstract: A plastic coating material such as a protein is coaxially extruded to surround an extruded meat prod.

Title: Differential blood particle counting process - uses speed of particles when subjected to unidirectional electrical field
IPC: G01N15/12
Filed: 1973-07-02

Title: Hollow rotary coal cutter and discharge system - rotates about vertical axis and discharges into hollow arm assisted by closure plate
IPC: E02F3/24
Filed: 1976-11-15
Abstract: A hollow rotary cutter particularly for removing coal from a vertical face in a mine is mounted in a horizontal hollow arm (1) through which the cut material is conveyed rearwards. The cutter (4) is semicircular in shape, rotating inside a semicircular housing (2) attached to the top of the arm. As the cutter rotates about a vertical axis (5) on the front edge of the arm, cut material collects behind a fixed plate (6) inside. This then pushes the material through an opening (7) in the top of the arm, to fall inside. This discharge action can be assisted by a piston. To make the cuts easier, steam can be injected into the ground through jets.
