Title: Rotary machine oil lubrication system - has small reservoirs each side of shafts enlarged centre to ensure starting lubrication
IPC: F16C33/10
Filed: 1973-03-29
Abstract: The oil lubricating system for gas turbines, pumps etc., has the centre portion of the shaft enlarged to form a solid, central collar. The gap between the collar and the housing is much narrower than that between the rest of the shaft and the housing. The housing has a large oil reservoir at its base and two smaller reservoirs higher up, each side of the collar. When the shaft rotates, oil in the large reservoir is driven by the swirling air around the shaft up into the smaller reservoirs so that, when the machine stops, oil remains in them. When starting up after a long stoppage the central collar is lubricated by the oil trapped in the small reservoirs.

Title: Valve for draining containers by pressurised gas - connects gas supply and simultaneously opens drain
IPC: F16L37/413
Filed: 1974-03-28
Abstract: The valve connects an outlet to the drain pipe which reaches almost to the bottom of the container and simultaneously connects the gas supply pipe to the container. The drain pipe is plugged at the top but is connected to a surrounding chamber containing annular valve member. A seal is retained between a spring and sliding plunger which is actuated by a handle. With the handle vertical, the valve is closed and the seal is compressed. When the handle is rotated, the seal is displaced from its seat and an annular gap is formed around its periphery. Gas can then pass into the container, forcing the liquid up the pipe and through now uncovered orifices.

Title: Linear frequency controlled oscillator - varactor control in feedback loop with frequency to voltage converter
Inventor: COUET JACQUES
IPC: H03C3/09
Filed: 1974-06-07
Abstract: A variable frequency oscillator providing a linear response, i.e. change in frequency, for a linear increase in the input control voltage, overcomes the sensitivity of circuits employing two nonlinear elements compensating each other. The basic circuit consists of an oscillator (1) whose frequency is dependent on a varactor circuit controlled by a voltage or current level fed to its input connection (VS). The control signal is derived from a feedback loop from the output (4). The feedback output fraction is passed to a frequency to voltage converter (2) and then to a comparator and error amplifier (3). The comparator also receives the external control signal (Vk).
