Abstract: 1475995 Centrifugal pumps SIMMS GROUP RESEARCH & DEVELOPMENT Ltd 5 July 1974 [13 July 1973] 33563/73 Heading F1C A submersible pump, e.g. for pumping fuel from tanks, is driven by an electric motor having its commutator 21, Fig. I, and brushes (not shown) normally submerged in fuel at a level 30. To maintain the fuel in the motor housing at the level 30, the pump inlet 26, Fig. 3, is extended vertically by a tube 29. Moreover, the outlet conduit (25), Fig. 4 (not shown) extends to a similar level and is connectible to a supply pipe. A pair of series-connected thermistors (39, 40), Fig. 5 (not shown) may be arranged in the motor housing, one above and one below the level 30, so that if the level should fall below level 30 the electrical potential between the thermistors alters and this is sensed by a Schmitt trigger (36) which then opens an electronic switch (34) to shut down the motor and thereby avoid the risk of igniting the air/fuel mixture in the motor casing.

Title: Winding impregnated yarn onto mandrel to form hollow body - by controlling mandrel speed dependent on yarn position
Inventor: LEVEL BERTRAND
IPC: B29C53/66
Filed: 1975-02-19
Abstract: A device for winding impregnated yarn onto a mandrel to form a hollow body includes a main drive shaft connected by a clutch to a mandrel drive shaft and also connected via a transmission to a yarn traverse guide guiding the yarn onto the mandrel. The position of the yarn being fed onto the mandrel is detected to actuate opening of the clutch to control the speed of the mandrel drive shaft and therefore the mandrel speed, and a sensor detects the relative angular positions of the main drive shaft and mandrel drive shaft to allow controlled acceleration and deceleration of the mandrel to ensure that the mandrel is always rotating at the correct speed as yarn is fed onto it. The arrangement is simple and automatically controls the mandrel to ensure uniform winding of the yarn onto it.

Title: Two-part conveyor for crushed ore - adjusts inclination of receiving and disposal belts as they are extended into receiving position
Inventor: SIDELNIKOV V G
IPC: E02F3/348
Filed: 1975-04-18
Abstract: The conveyor is of the type carried on a movable carriage and having an operating element which is pivotably carried between two parallel supports and capable of being moved under the crushed or run-out, the element consisting of two parallel sectors which at their lower ends are connected by a wedge-shaped member, which later connects with the forward collar of the inclined receiving belt whose rearward roller forces the link with the horizontal disposal belt.
