Title: Machine for the measuring and correcting of the unbalance of rotating workpieces
IPC: G01M1/30
Filed: 1957-05-17
Abstract: 852,475. Measuring rotor unbalance electrically. AVERYS Ltd., [formerly AVERY Ltd., W. & T.] (Schenck Maschinenfabrik G.m.b.H., C.). May 17, 1957, No. 15697/57. Class 40 (1). [Also in Groups XIX and XXII] A machine for measuring and correcting unbalance comprises an unbalance measuring apparatus 1, an indicating unit 2, and an unbalance correcting device 3, the indicating unit 2 incorporating two indicators 21, 22, each having means for preserving its indication after completion of the measurements, and switch means so arranged that as one indicator 21 (say) receives a measurement, the other, 22, can furnish an indication preserved from the previous measurement. In operation a workpiece 17, e.g. the rotor of an electric motor, is tested at 1 and an indication is given on a screen 21, but this remains invisible since the screen is not illuminated. When the workpiece is trans-  ferred to the correcting device 3, at which either a hole is drilled or a balance weight applied, the screen 21 is illuminated. A second workpiece can then be tested and its unbalance indicated on the screen 22, this latter being illuminated only when the second workpiece is transferred to the correcting device 3. A circuit to perform these operations is described (Fig. 4, not shown). An indicator is shown in Fig. 5. It consists of two stirrup-shaped luminous discharge tubes 73a, 73b, connected to the moving coils 74a, 74b of two wattmeters. These coils are fed with currents or voltages originating from the oscillation receivers of the measuring apparatus 1, and the field coils 75a, 75b are fed with current from a reference phase generator (not shown), the rotor of which is synchronized with the rotation of the workpiece 17. Two such indicators are used, one for each plane in which the body is to be balanced, and the crossing- points of the pairs of discharge-tubes 73a, 73b indicate the unbalance in each plane. To retain the indication after measurement, a spring 102 on each stirrup is attracted by an electromagnet 103 curved about the axis 72aa. If desired, the correcting device 3 may be automatically controlled by the positions of the stirrups 73a, 73b. Specification 744,295 is referred to.

Title: Improvements in or relating to directional radio systems
IPC: H04J1/12
Filed: 1962-04-25
Abstract: 978,862. Multiple channel transmission systems. SIEMENS-HALSKE A.G. April 25, 1962 [April 28, 1961], No. 15702/62. Heading H4L. In an arrangement in which a number of high frequency channels are transmitted over a common aerial system, the channels are combined at the transmit station and distributed at the receiver station in a manner which minimizes the differences in transit time between channels and this difference is further minimized by connecting a delay distortion correcting device in each transmit and/or receive channel. The arrangement, Fig. 2 for a four-channel system comprising four transmitters connected to terminals a-d and four receivers connected to terminals a<SP>1</SP> to d<SP>1</SP>, includes a common aerial system A and a transmit and receive distributer WI and WII, respectively. Each distributer includes four filters, one associated with each channel which pass signals in that channel with little energy loss and acts as a low loss reflector to the signals in the other channels and two circulators, e.g. RG1, RG2, around which the signals are channelled in the direction of the arrow. The difference in transit time between channels is minimized by connecting the transmitters and receivers to terminals a-d and a<SP>1</SP>-d<SP>1</SP> in such a manner, e.g. Fig. 3, that the signals in each channel are subjected to three filter reflections in passing from a transmitter to its associated receiver. Considering transmitter 2, its signal is applied to terminal c, is passed by filter Fc, is transferred from circulator RG2 to RG1, is reflected by filters Fb and Fa, is transmitted via line L1, the aerial system and line LII to receiver circulator RG<SP>1</SP>, is reflected by filter Fa<SP>1</SP> and passed via filter Fb<SP>1</SP> to receiver 2. The delay distortion correcting device, Fig. 9, which is connected in each channel, comprises two wave guide sections H 1 , H 2  disposed parallel to each other and coupled via aperture L to form a 3db directional coupler and extended to form two tunable cavities forming parallel resonant circuits which are tuned to the appropriate channel frequency by a common control.

Title: Motor driven impeller pump
IPC: F04D13/06
Filed: 1965-04-13
Abstract: 1,079,896. Electric motors. CRANE CO. April 13, 1965 [Sept. 3, 1964], No. 15760/65. Heading H2A. [Also in Division F1] In a motor driven pump some of the pumped liquid is delivered through passages 36 to a rotor chamber 34. The major part of this liquid returns to the pump chamber via rotor clearance 42 forming a fixed orifice, chamber 46, righthand bearing 33, hollow shaft 38, radial pasages 45, variable orifice 50, and passages 47 in the impeller 37. The remainder returns via the left-hand bearing 33 and clearance at bore 19. The variable orifice 50 is controlled by axial movement of the radial passages 45 relative to the fixed surface 17, and thereby by the thrust exerted on the shaft 38 by the impeller 37. Thus, since the variable orifice controls the pressure in the chamber 46, the pressure difference across the rotor 39 is automatically adjusted in accordance with this thrust and thereby produces the necessary balancing thrust. The bearing 33 may be of carbon. The balancing liquid additionally provides cooling and lubrication and acts as a cushion to prevent abrasion of the end plates 41 of the rotor 39. In an alternative embodiment, Fig. 3 (not shown), the degree of opening of the radial passages is controlled by the left-hand end of the left-hand bearing.

Title: Improvements in apparatus for use in determining the principal axis of inertia of a body
IPC: G01M1/10
Filed: 1944-08-21
Abstract: 586,976. Determining dynamic unbalance. VICKERS-ARMSTRONGS, Ltd., and WALLIS, B. N. Aug. 21, 1944, No. 15965. [Class 106 (ii)] In apparatus for determining the dynamic unbalance of a rotary body, the latter is suspended or supported with ability to swing or rock about a fixed pivotal axis in such a manner as to be free also to oscillate about an axis perpendicular to the said pivotal axis under the 'influence of the differential momentum of any dynamically unbalanced masses in the composition of the body, means being provided for detecting and measuring the amplitude of any such oscillation. As shown, a fly-wheel 21 under test is secured to a vertical strip 18 having a cylindrical head 181 through which passes a horizontal pivot 16 resting upon adjustable pallets borne by two aligned halves of a gantry 10. A hand winch operating blocks and tackle 23 is provided to assist in lifting the body under test. A lever 25 is attached to the head 181 for the purpose of swinging the test piece about the horizontal pivot 16. A tube 26, also secured to the head 181, carries a permanent magnet 34 in the field of which are placed a pair of coils 27, one on each side of the strip 18, so that when the fly-wheel rotates about its axis, as allowed by torsion of the strip 18, a current is induced in the coils 27, which is measured by a mirror galvanometer 29. A lamp 36, carried by the magnet 34, is arranged to throw a beam of light on to a screen 37 upon which are marked horizontal lines to indicate the desired range of swing of the test piece about the horizontal pivot. In use, a series of stations I, II, III, &c. are marked on the test piece (Fig. 2) and, when the latter has been adjusted so that the first station is adjacent to a pointer 40, it is swung through the desired range by the lever 25 and the peak current indicated by the galvanometer is observed. This procedure is repeated for other stations and the galvanometer readings so obtained are plotted as ordinates against the angular positions (station numbers) as abscissµ. The peaks on the curve indicate the angular position of the out-ofbalance masses and their weight and position with respect to the central plane perpendicular to the axis of the test piece may be calculated from the amplitude of the curve. When counter-weights have been attached, the experiment is repeated and, unless correction has been exact, another curve of smaller amplitude will be obtained. The vectors representing the amplitudes of the first and second curves respectively are then drawn in the form of a vector diagram, from which the true counterweights and their positions may be ascertained.
