Patent GB-840627-A (GB)
Abstract: 840,627. Rotor balancing. NEMEC, J., and KUHN, L. Jan. 30, 1957 [Feb. 13, 1956], No. 3301/57. Class 40 (1). In a rotor balancing system using a wattmeter as indicator a selsyn-type transmitter has its magnetized rotor driven by the rotor under test and its three-phase stator connected to the similar stators of two or three selsyn receivers whose rotors are normally fixed but can be adjusted manually; the watt-meter has one coil fed from the rotor of one of the selsyn receivers and the other coil supplied with a voltage compounded from the output of the rotor(s) of the other receiver(s) and the output of one or two pick-ups associated with the bearings of the rotor under test. This system eliminates uncertainty in the zero reading of the wattmeter due to components of higher frequency representing vibrations produced otherwise than by unbalance of the rotor. In the Figure the transmitter 2 is coupled to the rotor 1 under test and reproduces in the receivers 40, 50, 60 a rotating magnetic field of frequency equal to that of rotation of 1. The phases of the output voltages of these receivers depend on the angular positions of the respective rotors which are manually adjustable. Pick-ups 9, 10 generate voltages representing the unbalance vibrations at the two bearings of the rotor 1 and these voltages are combined in units 11, 12 with any desired fractions of the outputs of rotors 50, 60 by means of switches 13, 14 and potentiometers 15, 16. The unit 8 mixes the outputs of 11 and 12 in any desired proportion and applies the result to the watt-meter W. In operation, switches 13 and 14 are opened and the rotor 40 turned until the watt-meter reading is a minimum (position of unbalance), any difference in output between 9 and 10 being compensated by adjustment of unit 8. Rotor 40 is then turned through 90 degrees and the wattmeter reading noted (magnitude of unbalance). Switches 13, 14 are now closed and adjustment made of rotors 50, 60 and potentiometers 15, 16 until the watt-meter reads zero for all positions of rotor 40, i.e. the outputs of the pick-ups are completely neutralized. A calibrating mass is now added to rotor 1 and readings of position and magnitude taken with switches 13, 14 closed and potentiometers 15, 16 at their previously-found settings. From these readings the amount and position of the extra weight needed to balance the rotor 1 can be determined.

Patent GB-2191817-A (GB)
Title: Fuel tank for a motor vehicle
Inventor: BROWN ROBERT KENNETH
IPC: F02M37/00
Filed: 1986-06-19
Abstract: A saddle-type fuel tank 10 has two wells 12, 14 which, when the fuel level in the tank drops, are separated from one another. To enable the fuel pump 22 to draw fuel from both wells, a branch line 36 leads from one well over the bridge between the wells and into the other. In a fuel injected engine, part of the fuel withdrawn from the tank is returned through a return line 32. The branch line 36 leads into the return line 32 and has a restriction 38 immediately upstream of the junction between the lines. The pressure reduction thus produced causes fuel to be sucked through the branch line from well 14 into well 12 from which the fuel pump draws its feed. <IMAGE>

Title: Cathodic arc plasma deposition of hard coatings
Inventor: RANDHAWA HARBHAJAN S
IPC: C23C14/32
Filed: 1987-08-13
Abstract: Metal is evaporated using a pulsed cathodic arc source in a vacuum chamber optionally filled with a low pressure gas ambient or dopant gas to form the hard coating on the surface of the substrate. This deposition process improves the reproducibility of color and wear resistance down to very low substrate temperature (greater than or equal to about 50 DEG C.). The films may be deposited on cosmetic or functional substrates and may consist of nitrides, carbides, and carbonitrides, of at least one of titanium, zirconium, titanium-zirconium, titanium-aluminium based on systems and doped systems of the foregoing systems. Adhesion of the coatings may be further enhanced by appropriate biasing of the substrate. The film compositions, hence color, can be suitable adjusted to eliminate the use of gold for decorative applications.

Title: Voice recognition using an eigenvector
Inventor: NAKAMURA SHOGO
IPC: G10L17/00
Filed: 1987-10-05
Abstract: A voice pattern in the form of a matrix and comprised of a plurality of frames, each including time-spectral information and temporal information, is formed from an unknown input voice signal. The voice pattern is compared with each of the voice patterns of a library of known voices partly to select a plurality of candidate voices. Each of the library voices has a predetermined eigenvector and an inner product frequency distribution of inner products between the eigenvector and the frames of its voice pattern. Then, inner products between the voice pattern of the input voice signal and the eigenvector of each of the candidate library voice are calculated. One of the plurality of candidate library voices whose predetermined inner product frequency distribution is most similar to one of the thus calculated inner product frequency distributions is selected to identify the input voice signal.

Filed: 1988-01-21
Abstract: A display cabinet has a series of rigidly interconnected similar parallel frames, each including a standard 18 set back from the front of the cabinet and inclining rearwardly to its top. The standards carry supports 26 for shelves 25 located between frames, their fronts in a plane parallel to the standards 18. Glass front panels 32, their main lower parts in front of and inclined parallel to the standards 18 are supported closely adjacent by a transverse channel 31 in which their bottom edges are pivotally engaged so each can be swung forwards to open position, or back to normal closed position when their upper parts, which are rearwardly curved, come to rest on a counter 22 mounted on the frames 19, means 33, 34 being provided for releasably holding the front panels in closed position. As a result of the absence of support frame at the front of the cabinet, between the sections of the cabinet, the unit has enhanced visual appeal and gives a clear presentation of the cabinet contents.   <IMAGE>
Patent GB-2200920-A (GB)
Title: Abrasive article
Inventor: MOORE MICHAEL W
IPC: B24D3/00
Filed: 1988-01-22
Abstract: In a method of forming an abrasive article a mesh material is applied with insulating material over areas which do not require abrasive, the insulating material being absorbed into the mesh material. The mesh material (16) is then laid onto a surface (12) of electrically conducting material and metal is electro-deposited onto the discrete areas of the mesh not bearing the insulating material. Abrasive is added so that it becomes embedded in the metal. The resulting material with metal and abrasive areas is stripped off the surface. The preferred insulating materials are ink screen printed onto the mesh, or hot melt adhesive perforated to define openings and then applied to the mesh to penetrate the mesh.
