Title: Controller for grain grinding - utilises weight of grain in chute to activate motor start or stop switches
IPC: B02C23/02
Filed: 1977-01-21
Abstract: A grinding machine motor is controlled by weight of cereals from a hopper passing along a chute. Weight of cereals displaces the chute to activate switches to start or stop the motor. Cereals in a hopper (1) pass via a neck (4) onto a platform (5) acting as base of a chute (8). The chute contents pass into an extension (6) of a cover (7) with an orifice (2) leading to the grinding machine. Cereals in the chute cause it to pivot (9) against a counterweight (11) to operate electrical switches (12). This enables the motor to be switched off when no cereals are present.

Title: Discriminating presence of detector with alarm system - is in form of rubber foam mat incorporating separated conducting sheets
IPC: G01G19/44
Filed: 1977-05-16
Abstract: The presence sensors detection system has a control circuit to which is associated a capacitor sensor. This capacitive detector has a first fixed conducting sheet and a second conducting sheet maintained at a distance from the first. The second sheet acts on the first against an elastic force due to deformation of a material. The second sheet (3) of the detector (1) has a surface deformability such that the application of a deformation force on a given surface of this sheet does not tend to move the two sheets close together in a zone (5) approx. equivalent to the give surface. The intensity of the elastic force is sufficiently low so that the approach of the two sheets under the effect of a deforming force is independent of the force intensities associated with presences to be detected. The elastic force is exerted by a dielectric (4) arranged between the two sheets and made from an elastic material such as foam rubber.

Title: Sealing arrangements for a rotating heat exchanger - ensuring maximum efficiency and minimum leakage with multiple adjusters
IPC: F16J15/16
Filed: 1977-10-26
Abstract: Regenerative rotating heat exchanger with a rotor formed of a heat-absorbent material mounted around a central shaft. The rotor is surrounded by a cylindrical body, an annular space being left between the rotor and the body. The body contains, at the opposite ends of the rotor, plates provided with openings to direct a fluid to be heated and a heating fluid across the rotor. The rotor is turned in order that the heat absorbent material may be displaced progressively from the hot to the cold fluid and back again. The cylinder is fitted at each end of the rotor with adjustable sealing devices which give a fine adjustment to allow for optional efficiency in performance. The arrangement allows the relationship of the joints to each other to be maintained permanently in the positions giving maximum leak-tightness. They avoid problems due to the erosion of parts by the particles which may be carried in the gases passing through the exchanger.
