Patent IT-1137049-B (IT)
Inventor: BOVONE LUIGI
IPC: B24B9/10
Filed: 1981-06-11
Granted: 1986-09-03
Abstract: In belt chamfering machines, the glass sheet being machined is gripped and conveyed during the machining (chamfering) of its edge between two facing portions of two belts. The rear belt extends downwards more than the front belt as it has to provide a support for the sheet at or in proximity to the edge being machined. Small sheets cannot be machined by known machines of this type because they would not be adequately gripped between the two belts. To obviate this drawback, the invention provides for the rear belt to be able to be adjusted in height so as to vary the downward projection of said belt relative to the front belt. At the same time, the position of the conveyors on which the sheets rest before and after machining can be adjusted to the same degree.
Patent IT-1177125-B (IT)
Title: Scotch yoke engine
Inventor: HENIGES WILLIAM BERNARD
IPC: F02B/
Filed: 1984-11-07
Granted: 1987-08-26
Abstract: The yoke type engine, with an adjustable orbital path of the slider effects piston stroke and compression ratio changes. The crank component has a crankpin which carries and positions the slider. The boss of the crank component is carried by a control shaft in an offset manner. Timing gears normally drive the control shaft in synchronisation with the crankshaft to maintain a constant stroke and compression ratio. Relocation of the gears by an actuator causes the control shaft to rotationally advance or retard to reposition the crank component, to in turn alter the orbital path of the coaxial crankpin and slider relative to the crankshaft axis. Accordingly, high and low compression orbits for the slider may be effected to best suit engine loads. A variable length throw couples the slider to the crankshaft.

Title: Temp. or pressure responsive valve
Inventor: PADUCH STANLEY RAYMOND
IPC: G01L7/06
Filed: 1980-11-21
Granted: 1986-08-13
Abstract: The valve produces a hydraulic pressure signal proportional to temp. or pressure. It comprises a number of bellows (22,32,28,38) acting on a valve nozzle plate (14) so that the temp. signal from a probe (10), which is a gas pressure, moves the nozzle plate to control the flow through the nozzle as a function of temp. thus producing a metered pressure proportional to temp. The bellows are arranged to minimise temp. error in the valve, the insides of the bellows (22,32) being exposed to the fluid pressure prevailing on opposite sides of the nozzle plate while the controlling gas pressure signal is applied to the exterior of the bellows (28,38). The chambers between the bellows are evacuated. Where the temp. sensed is engine inlet temp. the metered pressure may be used to control the fuel through the turbine engine as a function of the engine inlet temp.

Granted: 1992-04-03
Abstract: The device referred to in this document is an electro-mechanical apparatus which is fitted without touching the usual structures and functions of the abovementioned lifts and elevators and at the same time remaining within safety limits at all times. The installation and functioning of the device is very simple. A small motor is joined with the winch of the existing installation which is necessary to level the stops.
