Patent EP-0057680-A4 (EP)
Title: Dual motor drive system.
Inventor: MELOCIK GRANT C
IPC: B60L3/00
Filed: 1980-08-18
Abstract: An electrically operated dual motor drive system having first and second reversible traction motors (14, 16) driven by a power source (18). Motor control circuitry (10, 12) for controlling the direction of current flow through the motors (14, 16) is designed to be actuated by only two coils (36, 42). Preferably, control circuits (10, 12) employ an arrangement of normally open (32a, 32b, 38a, 38b) and normally closed (34a, 34b, 40a, 40b) contacts such that the two motors (14, 16) operate in reverse directions in the event of a complete system malfunction. A line contactor (20) is advantageously utilized to simultaneously serve as a main power disconnect for a variety of motors within the system. The present invention overcomes the disadvantages of the prior art techniques through the provision of uniquely designed motor control circuitry which is selectively activated by only two coils (36, 42) instead of the previously used four, thereby resulting in substantial cost and space savings.

Title: Prosthesis fixation to bone.
Inventor: MEYER BENJAMIN S
IPC: A61B17/16
Filed: 1983-01-21
Abstract: A two-part system for fastening an artifical joint component to bone with high early strength. The first part is a sleeve (34) defining an external geometric pattern of projections (128) which engage the bone (114) when implanted. The sleeve (34) performs none of the motion functions of the joint. In one embodiment the projections (128) are elongated and act in a self-broaching manner. In another embodiment the projections (128) are threads which have an outside diameter which may vary in one or more tapers, to best achieve anchorage in cancellous bone (114) in a prepared bony canal or cavity. The inner bore (36) of the sleeve (34) is a cone of a mechanically self-locking taper. The second part (40), which performs at least part of the motion function of the joint, has a mating external taper (42) which is driven into the taper within the sleeve (34) to be locked therein. The second part (40) may of itself extend through the sleeve (34) and into the prepared bony canal for addition stabilization and fastening. There is also provided a two-part system for fastening a dental prosthesis (210)to the jawbone (212) having as a first part (216), an externally threaded thin wall sleeve (216) which resides entirely within the jawbone (212). The threads (218) or other surface features are confined to the area near the point where the prosthesis (210) enters the jawbone (212). The sleeve (216) has integrally, or accomodates, a non-threaded stem (230) which extends relatively deeply into the jawbone (212). The inner bore (222) of the sleeve (216) is a cone of a mechanically self-locking taper. The present invention is applicable to a prosthetic device for any body joint.

Patent EP-0187852-A4 (EP)
Title: Microwave electron gun.
Inventor: MADEY JOHN M J
IPC: H01J23/06
Filed: 1985-07-08
Abstract: An electron gun (10) that suppresses the non-linear space charge forces and phase-dependant focusing forces that are chiefly responsible for the high emittance of conventional electron guns. The gun comprises a resonant microwave cavity (15), a cathode (12) mounted in the cavity wall, and a momentum analyzer system (17). The resonant microwave cavity, when supplied with microwave power, supports an electromagnetic field having a high-gradient electric component directed along an acceleration axis. The cavity is formed with an exit aperture (32) at a location relative to the cathode such that emitted electrons are accelerated along the axis and pass through the exit aperture. The cavity length is chosen to allow the microwave field within the cavity volume to accelerate the electrons to an energy of about 0.5-1.0 MeV prior to the electrons' passing through the aperture. Bunching is provided by the momentum analyzer. An electron emerging from the cavity has an energy determined by the phase of the microwave field at the time of that electron's emission. Those electrons having energies corresponding to the desired initial phase value are permitted to pass through the momentum analyzer, thereby forming a prebunched electron beam for injection into a linear accelerator.

Patent EP-0297132-A4 (EP)
Title: Method for manufacture of lightweight frothed mineral wool panel
IPC: D21J1/20
Filed: 1988-01-11
Abstract: Method for the manufacture of low density mineral wool structure panels by frothing a dilute aqueous dispersion of mineral wool, lightweight aggregate, binder and a small amount of amine-based cationic surfactant onto a non-woven scrim cover sheet (43). The resultant froth, a mass of very well formed, uniform bubbles, are of a nature that rapidly dewater and burst to concentrate the solids in the mass. The bubbles are readily broken without loss of the uniformly voided structural configuration by a first application of brief pulses of high vacuum followed by further dewatering under vaccum and rapid drying by passing high volumes of heated air through the voided mass without collapse of the structure to result in lightweight structural mineral wool panels.

Title: Disc recording apparatus
IPC: G11B7/125
Filed: 1988-02-24
Abstract: A disc recording apparatus for recording data such as information concerning musical performance on a recording disc (1) to which absolute addresses have been imparted in advance. Vibration during the recording operation and unexpected track jump due to defect in the recording disc are detected relying upon the discontinuity of absolute addresses reproduced from the recording disc (1). In case the track jumping has taken place, the laser power of the optical head (12) is dropped to the reproduction level and the track jump control is effected to give access to a desired track. The recording operation is then resumed for the track.

In the most preferred embodiment of this invention, the fluid dispensing and reciprocating abrading tool (7) of the present invention is formed integrally with a sleeve comprising a shank portion (100) designed to be juxtaposed within a handpiece and to be directly driven by the eccentric driver.
Patent EP-0490964-A4 (EP)
Title: Improved data compression apparatus
IPC: G06T9/00
Filed: 1990-09-05
Abstract: The improved data compression system concurrently processes both strings of repeated characters and textual substitution of input character strings. In this system, the performance of data compression techniques based on textual substitution are improved by the use of a compact representation for identifying instances in which a character in the input data stream is repeated. This is accomplished by nesting a run length encoding system in the textual substitution system. This structure adds the recognition of runs of a repeated character before the processor performs the textual substituted data compression operation. A further performance improvement is obtained by expanding the alphabet of symbols stored in the compressor's dictionary to include both the characters of the input data stream and repeat counts which indicate the repetition of a character. The handling of these repeat counts by the textual substitution based compression technique is no different than the handling of characters, or certain modifications are made in the handling of repeat counts.

Title: Improved enhancement of chemiluminescent assays
Inventor: BRONSTEIN IRENA Y
IPC: C07C43/178
Filed: 1994-03-15
Abstract: Chemiluminescent bioassays for the presence or concentration of an analyte in a sample use 1,2-dioxetanes as substrates for the enzyme of an enzyme complex that bind to the analyte. The chemiluminescence obtained from the decomposition of the dioxetane triggered by the enzyme through the formation of the corresponding 1,2-dioxetane oxyanion of the enzyme complex is enhanced by the addition of TBQ as an enhancement agent. Other polymeric quaternary onium salts can be used as enhancement agents in conjunction with enhancement additives which improve the ability of the enhancement agent to form hydrophobic regions in the aqueous sample, in which regions the 1,2-dioxetane oxyanion and its chemiluminescent decomposition products can be sequestered. A kit for performing such assays is also provided.
