Title: Winch with ratchet drive - has lockable linkage between driving pawl arm and actuating rod for faster rotation of drum
Inventor: HARVEY JUN THOMAS GEORGE
IPC: B66D1/06
Filed: 1977-01-10
Abstract: The ratchet winch has a driving pawl engaging with the ratchet wheel and moved by an arm. A locking mechanism prevents the wheel running backwards, and an actuating rod moves the arm to and fro. A linkage couples arm and rod together, and is lockable to allow arm and bar to rock as a unit in relation to the frame to turn the drum faster. The rod swings on the link pin to turn the drum under heavy load, when the arm rocks in the frame through a smaller angle than the rod. When arm and rod pivot in relation to each other, the rod can be extended from the frame to generate the arm rocking movement. There can be actuating levers on the rod, coupled to the frame in order to impart a rocking movement to the arm.

Patent DE-2737809-A1 (DE)
Inventor: KUNZ THEODOR ELMAR
IPC: C12G1/032
Filed: 1977-08-22
Abstract: In this fermentation vessel (1), must is forced up from the fermentation chamber (7) under the pressure of the fermentation gases through the fermentation gas discharge pipe (23) into the overflow chamber (9). If the level in the fermentation chamber (7) decreases to the height of the orifice (26), fermentation gases escape through the fermentation gas discharge pipe (23) into the overflow chamber (7). Because of the pressure drop in the fermentation chamber (7), the valve (30) opens and must flows from the overflow chamber, disturbed by rising fermentation gas, in an irregular flow back into the fermentation chamber and during this dissolves pigments out of the pomace cap (55). The valve (30), for radial deflection of the must, has a plate-shaped valve body (31). As a tensioning means for the valve (30), a weight (33) is provided which exerts a constant closing force which is independent of the opening travel. <IMAGE>

Title: Detection method for surface deposits - uses differential heat flow measurement in comparison with reference surface
Inventor: HOLMES ELMOND A
IPC: G01N25/18
Filed: 1977-12-30
Abstract: The detection and measurement of deposits, such as scale or wax on different types of surfaces, is determined by thermal measurements on a test sample compared with a reference. This procedure is sensitive enough to detect deposits without having to wait until they effect operation of a system. A test and a reference surface are submitted to a fluid environment and are subjected to heat flow in a known relationship. The transfer of heat between the surfaces and their fluid environments is compared. Heat flow is applied differentially to decrease difference in temp. of the fluid. These measurements are then used to determine their effect on deposit formation.
