Title: Axial ventilating fan blade attachment system - has root of each blade bolted between wedges in hole in hub
IPC: F24F/
Filed: 1975-10-14
Granted: 1981-02-10
Abstract: The axial ventilation fan in which the number of blades can be varied without dismantling the rotor, has the roots of the blades retained in holes in the hub. The hub has a main shroud integral with the annular hub portion, and a shallower shroud portion which bolts onto the main portion, the bolts passing through the roots of the blades, and at the same time retaining a wedge block against each face of each blade root, fitting into a cylindrical hole for each root. The bolts can pass through slotted holes to permit play of the locking elements. In an alternative design, the wedge blocks can be shaped to permit an adjustment of the angle of the blade.

Title: Fuel burner
Inventor: FONTANA IPPOLITO
IPC: F23D/
Filed: 1989-07-04
Granted: 1992-05-26
Abstract: The present invention concerns a burner for liquid fuels (gasoline, diesel oil, etc.) comprising a pump (3) started by an electrical engine and provided with a pipe (4) to suction fuel an with two additional pipes (7, 11) to introduce said fuel, pipe (7) sending it to the sprayer (8) of said burner, and pipe (11) to a device (12).

Title: Refrigerating device provided with speed-controlled compressor
Inventor: ALDO MICHELETTO
IPC: F25B49/02
Filed: 1989-05-31
Granted: 1992-04-21
Abstract: The present device comprises a compressor started by an electrical engine, said engine being fed by a power source with unidirectional current. Said compressor is linked to a command and control system aimed at changing the rotation speed of the working electrical engine of said compressor, so that changes in the power absorbed by said engine be limited to the predetermined value range. The compressor power absorbed by the engine is kept at a constant value by the control and command device.As a consequence, refrigerating capacity changes of the device are also minimised despite working temperature (evaporating temperature).<IMAGE>

Abstract: 1,113,322. Photo-electric speed measuring. DECCA Ltd. 6 Sept., 1965 [28 Sept., 1964 (2)], Nos. 39374/64 and 39445/64. Heading H4D. In Doppler-effect apparatus measuring the speed V of a reflecting object and utilizing a coherent visible or infra-red light beam from a laser, frequencies may arise in the laser which produce spurious signals affecting correct operation of Doppler beat frequency tracking circuits; according to the invention the transmitted light beam after it leaves the laser, or the reflected light beam, is modulated at a predetermined frequency of a different order to that of the Doppler beat frequency and means responsive to the latter in a sensitive device receiving light both reflected back from the moving object and directly from the laser is arranged to respond to signals containing components of the modulation frequency. The beam modulation may be effected by a Kerr cell or, as in the embodiments, by an apertured rotating disc. In one embodiment a first photocell 20, by mirror 12 or polarization prisms, receives both transmitted and reflected light whereas a second photo-cell 14 receives transmitted light only; the difference of the photocell outputs is fed to mixers 21, 22 also fed in phase quadrature from a voltage-controlled oscillator 34 in a frequency tracking arrangement incorporating a phase-sensitive detector 30 fed from a photo-cell 31 which produces an A.C. voltage at the modulation frequency. The frequency of oscillator 34 is measured, to give speed V, or may control the speed. To ensure correct locking of the frequency tracking arrangement a low-frequency sweep generator 36, a reference generator 38, a detector 40, and a relay 42 and associated contacts 37, are utilized; a lamp 39 is energized when relay 42 signals that tracking is correct. In another embodiment, Fig. 2 (not shown), the laser is of the kind having mirrors at the ends, a photo-cell receiving light directly from the laser and amplified reflected light from the moving object; the output by the cell feeds directly into mixers 21, 22.

Abstract: 1,111,755. Transistor gain control circuits. MARCONI CO. Ltd. 12 Oct., 1966 [17 Jan., 1966], No. 2056/66. Heading H3T. In a cascade wide-band tuned amplifier, in which the gain is varied by varying the bias on the input transistor A1, this transistor is shunted by a resistor A10 between collector and earth, so as to reduce the changes in the current through the output transistor A2. This reduces its changes in output impedance as the gain is varied and so prevents distortion of the frequency response. As shown, the amplifier comprises three stages, the gains of transistors A1, C1 in the first and last stages being varied; these stages are tuned in the region of the lower frequency limit of the pass-band while the second stage is tuned in the region of the upper frequency limit.
