Title: Improvements in multi-stage turbo-compressors and gas turbines
IPC: F04D1/00
Filed: 1962-10-24
Abstract: 969,125. Centrifugal and axial-flow compressors; turbines. H. DOLZ. Oct. 24, 1962 [Nov. 3, 1961], No. 40238/62. Headings F1C and FIT. In a multi-stage compressor or gas turbine, the rotors are fixedly connected in a gastight manner with the casing so that the casing revolves with them, whilst the guide wheels of the individual stages are retatably supported in the interior of the casing and are restrained from rotation by gravity or magnetic force. The casing 1 of the multi-stage centrifugal compressor shown is rotatably mounted in bearings 3, 6 and carries rotors 11, 21, 31. Guide blades 15, 25, 35 are carried by guide wheels 14, 24, 34 which are freely rotatable on bearings carried by the rotors or by a casing end cover 5. The guide wheels are restrained from participating in the rotation of the casing and rotors by means of weights 20. A single weight 20 may be provided within each guide wheel, but preferably two are provided and are slidable on radial guides 19 so as to assume the positions shown. In the event of a guide wheel rotating as the result of the torque tending to rotate it exceeding the restraining torque exerted by the weights 20, both weights are thrown outwards by centrifugal force. This balances the guide wheel, and harmful effects due to lack of balance are avoided. The rotors may be provided with blades over their entire periphery. For small outputs, however, each rotor is provided with two diametrically opposed ducts only. The rotors may be of equal diameter but provided with differing numbers of blades appropriate to the requirements of each stage. Alternatively, the same number of blades may be provided in each rotor, those blades in excess of the requirements of each stage being closed by insertions. This facilitates the addition of a further stage to an existing compressor. The annular space between each rotor and the following guide blades may be provided with guide blades instead of being bladeless as shown. The compressor discharges through a hollow shaft 43 formed on the casing end cover 5, leakage between the rotating shaft and a stationary discharge connection 44 being prevented by a sealing gland 46 which may be of carbon-ring type, or a labyrinth packing. In the case of a compressor operating in a refrigeration or other closed circuit, the compressor and its driving motor may be enclosed in a gastight casing. In a modification, the guide wheels are journalled on a single common shaft, which may be hollow at one end or both ends for the admission and discharge of the gas. The compressor may be of axial-flow type. The invention may be applied to gas turbines.

Title: Pressure peak gauges
IPC: G01L23/02
Filed: 1970-08-20
Abstract: 1,262,609. Pressure gauges. SULZER BROS. Ltd. Aug.20, 1970 [Aug. 20, 1969], No.40257/70. Heading G1C. In a gauge for measuring peak pressures in periodically varying gas pressures, such as in the cylinder of an I. C. engine, pressure surges are transmitted periodically, through a duct 18 to lift a piston 21; against the force of a measuring spring 33, by way of the head of a screw 22 and a flange 41 of an adjusting member 40, a screw 31 to a measuring member 26; over a distance no more than "S" and a measuring member 36 is also lifted out of functional engagement from a component 35 thus permitting a spring 37 to rotate member 36 in order to again abut the component 35. When the pressure drops the piston 21 is moved to the initial position by a disc spring 24 but the member 26 cannot follow since it is held by the member 36 and a gap would appear between the flange 41 of the member 40 and disc 23, which gap is closed by a spring 44 rotating member 40 into abutment with the disc 23, and as a result the measuring member 26 gradually moves upwards to compress spring 33 until the force exerted thereby cannot be overcome by the gas-pressure acting on piston 21 and since the rotational movement of member 40 is proportional to the stroke of member 26 the measured value can be read off a scale provided on a cap 48.

Abstract: 1,015,156. Protective arrangements. ETABLISSEMENTS MERLIN & GENIN. Nov. 6, 1962 [Nov. 16, 1961], No. 41911/62. Heading H2K. [Also in Division H3] An arrangement for detecting asymmetry in a polyphase system comprises a detecting device adapted to detect the passages through zero of the phase currents and to impart signals in response to these passages to a discriminating device which responds to asymmetry of the signals to give an alarm or trigger signal. The discriminating device may respond to differences between the intervals between successive passages through zero, Fig. 3, or to the difference between the intervals and a fixed reference interval, Fig. 4 (not shown). The detecting device, Fig. 1 (not shown), may comprise a saturable current transformer for each phase, the secondary windings being connected in series so as to provide a pulse at each current zero for application to a memory device B constituted by a multivibrator having transistors TR 1 , TR 2 . The output from the multivibrator renders a transistor TR 3  alternately conducting and non-conducting so that when no unbalance exists an inductor 21 becomes saturated every 120 degrees, i.e. once in every interval separating two successive pulses of the same polarity derived from the current transformers. This permits a capacitor C 1  to discharge through the inductor 21 and the transistor TR 3 . Should unbalance occur, there will be at least one interval every 360 degrees in which saturation does not occur, and in these intervals the capacitor C 1  can discharge through a transformer T 4  and a transistor TR 4  which is momentarily rendered conducting each 120 degrees by the multivibrator B. The resulting pulses through the transformer T @  charge a capacitor C 3  until the Zener voltage of a diode Z 1  is exceeded, the alarm or trigger signal then being given. In Fig. 4 (not shown) response is effected when the interval between successive pulses differs from the charging time of a capacitor. The current transformers may have different characteristics so that pulses are produced should one phase not be energized.
