Title: Temperature monitoring circuit for rotating mining machinery - has inductive pick-up and low-level pulse transmission for safe operation
Inventor: SIMONS PAUL
IPC: G01K3/00
Filed: 1975-03-15
Abstract: The monitor circuit for temperature rise in a braking disc of a conveyor belt mechanism consists of two induction coils with soft-iron cores connected in series with a temperature-sensitive switch (6) and diametrically arranged each side of the brake disc (1). In the same plane is a permanent magnet fixed to a synthetic resin moulding. Diametrically opposite in a similar housing is an induction coil with iron core, connected to a transistorised relay (9). If the temperature sensitive switch is closed, impulses induced by the permanent magnet in the coils (4, 5) are transferred to the transistorised relay by its pick-up coil. Overheating of the disc opens the switch (6) and no impulses are transmitted to the external circuit.

Title: Self-restoring type current limiting device - has conductive material between electrodes to evaporate when excessive current flows
Inventor: KAMINO TOSHIHIDE
IPC: H01H87/00
Filed: 1975-12-22
Abstract: One electrode is rigidly fitted into a hollow metallic cylinder and the other electrode is coaxially fixed within the cylinder through a cylindrical insulation. An insulating disc is opposite to the cylindrical insulation to form then an annular arrow gap between them. The gap is filled with a self-restoring type current limiting material to normally form a current passageway between both electrodes. The current limiting material is caused to be first evaporated in a narrower portion of the gap in response to a flow of overcurrent through it. After the current has been limited, the evaporated material is rapidly self-restored to its original good electrically conductive state.

Title: Partially defatted nuts esp. peanuts contg. glycerol - by treating with aq. glycerol soln. then roasting
Inventor: GANNIS PETER M
IPC: A23L25/00
Filed: 1976-10-14
Abstract: Process comprises contacting the de-fatted nuts with a glycerol soln. under conditions such that at least a part of the soln. is absorbed by the nuts. The nuts are then sepd. from the soln. and roasted. Partially de-fatted nuts, esp. peanuts, are food product supplied to satisfy a demand for a lower calorie product. However, such nuts are not stable to storage and when crunched are granular to chalky giving a disagreeable sensation in the mouth. Also when these products are dry roasted, oil is exuded which dirties equipment which requires costly cleaning. The above process improves the flavour, texture and storage stability of the product which are substantially those of the initial nuts before partial defatting. Exuding of oil on roasting is prevented.
