Title: Process for manufacturing prosthetic dental reconstructions
Inventor: WOHLWEND ARNOLD
IPC: A61C5/77
Filed: 1996-03-28
Abstract: A process for manufacturing a prosthetic dental inlay or prosthetic dental crown (1), or prosthetic dental bridge for fitting in a pre-prepared tooth cavity or on a pre-prepared stump (4), involves the following steps: the three-dimensional profile of the cavity or stump (4) is determined; a three-dimensional template for the inlay or crown, magnified by a predetermined factor, is made from a pre-treated prosthetic dental material and further treated to shrink it to dimensions matching those of the cavity or stump (4).  A working stump, magnified by the predetermined factor and in shape matching the three-dimensional profile of the cavity or stump (4), is produced from a material with more or less the same shrinkage factor as the prosthetic tooth material. The working stump is placed in the template for further treatment, the template being stabilised during the treatment. After the treatment, the working stump is separated from the template. The prosthetic tooth material and, if required, the material for the working stump is an oxide ceramics, specifically a zirconium oxide or aluminium oxide ceramics, or oxyde ceramics alloys.

Title: Disk cartridge anti-rattle mechanism
Inventor: SUMNER WAYNE A
IPC: G11B23/03
Filed: 1996-06-06
Abstract: A cartridge for a magnetic disk drive has a clamping mechanism which is actuated as the door (23) to the cartridge is closed when the cartridge is removed from the drive. The door covers the openings through which the cartridge is accessed by read/write heads. When the cartridge is removed from the drive, the mechanism (26) of the present invention clamps the recording disk against the cartridge shell to prevent rattle, which might otherwise damage the recording disk.

Title: X-ray image intensifier
Inventor: ROWLANDS JOHN A
IPC: H05G1/64
Filed: 1998-01-30
Abstract: An x-ray image intensifier includes a photoconductive x-ray detector having an electro-optic light modulator disposed on a photoconductive detector layer. The photoconductive x-ray detector absorbs x-rays passing through an object to be imaged to form an x-ray exposure of the object. An optical image of the x-ray exposure is generated when light passes through the photoconductive x-ray detector. An imager captures optical images of the x-ray exposure. A processor coupled to the imager digitizes and stores the optical images of the x-ray exposure captured by the imager at selected intervals.

Title: Sealing material made of expanded graphite and a method of producing the same
Inventor: SUGITA KATSUNORI
IPC: C09K3/10
Filed: 1997-06-26
Abstract: The invention relates to a sealing material made of expanded graphite and a method of producing it. In the sealing material made of expanded graphite of the invention, a surface layer portion of an expanded graphite base material 11 in which expanded graphite particles 1 are pressurized is subjected to a blast process or the like, whereby the weight of the expanded graphite base material 11 is reduced by a range of 0.5 to 3%, so that the diffraction peak of an X-ray diffraction of the exposed surface layer portion of the expanded graphite base material 11 is in a range of 26.52 to 26.48. In such an sealing material made of expanded graphite, the elongation rate and the tensile strength are improved, and also the flexibility is remarkably improved. Therefore, also extension of the application range of a product and improvement of the productivity of a product can be attained.      The sealing material may be preferably used in various kinds of sealing members for high-temperature use such as a packing, a gasket, a V-shaped ring, and a valve seat, and a sliding material such as a bearing, or a heat insulating, material for a high temperature vacuum furnace.

IPC: H04M1/715
Filed: 1998-07-27
Abstract: The Directed Telephone System (DTS) enhances the operation of group of telephones connected to a Central Office line. The system sends a brief pre-recorded message asking the caller to press one digit out of a menu of names and corresponding digits.  On receiving that digit DTS directs the incoming call to a particular telephone set and alerts only the called person by a unique ring code. The DTS provides personalised intercom calls using the existing normal telephones and alert the called person with the same ring code. The system also connects a fax call directly to the fax machine. A DTS unit can be constructed on a circuit board that can be fitted inside each telephone set during manufacturing or in a little box connected to each telephone. Suitable for multiple personnel homes, rented room dwellings, farms, small businesses, etc..

Title: Bale thrower control system
Inventor: BOE THOMAS CEDRIC
IPC: A01F15/08
Filed: 1998-10-15
Abstract: A baler for making parallelepiped bales is equipped with a bale ejector or thrower structure including a bale throwing pan supported by a four-bar linkage that is swung upwardly by a hydraulic throwing cylinder. A control valve structure including a solenoid-operated trip valve and a solenoid-operated pressure-relief valve is actuated for effecting pressurization of the throwing cylinder and throwing of a bale in response to a trip switch being closed in response to a trip pedal being rotated by a bale moving rearwardly on the throwing pan as it exits the baler bale chamber, the trip valve when actuated blocking a source of fluid pressure from normal communication with a fluid sump, and the pressure-relief valve when actuated being operable for maintaining the working fluid pressure at a value determined by a variable potentiometer connected in circuit with the solenoid of the pressure relief valve. The pressure of the fluid available for operating the throwing cylinder and, hence, the distance through which a given bale will be thrown, depends on the setting of the relief valve achieved through adjustment of the variable potentiometer. An interlock circuit is provided for preventing actuation of the throwing cylinder in the event that a shield structure, which surrounds the area occupied by the throwing pan, is lifted to an inoperative position, such lifting opening an interlock switch. An interlock relay switch is provided which, when energized, maintains the availability of power to a power port of a timer coupled for receiving a control signal when the trip switch is tripped, the signal acting to change the state of the timer so that it connects power to the trip and pressure-relief valve solenoids for a preset time, the interlock relay switch acting to open the current path to the timer power input port in response to the interlock switch moving to its normally open position in response to the shield structure being raised to a non-working position.
