Title: Environmental condition detector transmitter interface
Inventor: WHITTAKER RICK G
IPC: G08B25/10
Filed: 1999-01-25
Abstract: A transmitter interface board (12) for integration with a conventional environmental condition detector (16) (such as a smoke detector, carbon monoxide detector, etc.), for transmitting information on the operating status of the detector to a remotely located monitoring facility (20). The transmitter interface is connected to a detector circuit (16) in the condition detector in a manner such that the interface can detect alarm pulses emitted from the detector. Based on the number of alarm pulses emitted in a predefined interval the tranmsitter interface is able to determine the operating status of the detector. The operating status information is then sent by a transmitter (64) to the central monitoring facility.

Title: Transmitting system for small-sized vehicle
Inventor: KIHARA TERUO
IPC: F16H45/02
Filed: 1999-11-12
Abstract: In a transmitting system for a small-sized vehicle in which a crankshaft of an engine and an input shaft of a multi-stage transmission are connected to each other through a fluid transmitting device, the fluid transmitting device and a shifting clutch are mounted on the crankshaft. One of the fluid transmitting device and the shifting clutch is connected to the crankshaft, while the other is connected the input shaft of the multi-stage transmission through a primary reducing device. Provided in the crankshaft are an upstream supply oil passage connected to an oil pump, a downstream supply oil passage connected to portions to be lubricated of the engine, a flow-in bore which permits the upstream supply oil passage to communicate with the inside of the fluid transmitting device, and a flow-out bore which permits the inside of the fluid transmitting device to communicate with the downstream supply oil passage. Thus, when the multi-stage transmission is to be shifted, a shifting operation can be conducted lightly, irrespective of a creep phenomenon of the fluid transmitting device by bringing the shifting clutch into its OFF state.      Moreover, lubricating oil for the engine can be utilized to operate the fluid transmitting device and hence, an exclusive oil pump for the fluid transmitting device is not required.

Filed: 1998-06-03
Abstract: A method and device for treating for instance a paper pulp suspension with at least one treatment fluid has a treatment chamber, in which a rotor (1) rotates and carries a number of rigidly interconnected coaxial rotor rings (23) at its periphery, a number of stationary stator rings (25) being coaxially inserted between the rotor rings, so that at least two annular axial treatment slots (27) are formed between the rotor rings and the stator rings.  An inlet member (19) for the working medium and an inlet member (21) for the treatment fluid are arranged on one side of said treatment slots and an outlet for the treated working medium on the other side, the working medium with treatment fluid being subjected to a shearing in the slots. The treatment slots are formed in such a way that their radial extensions increase with increasing distance to the rotational axis (A-A) of the rotor so that a substantially homogeneous shearing velocity is achieved in all of the annular treatment slots.

Abstract: A swimming pool cleaning device (10) for automatically cleaning a submerged surface (12) includes a forwardly inclined housing (100) forming a flow passage (110) between the surface (12) to be cleaned and a suction hose (16).  A flow control valve (200) is operable within the flow passage (110) and includes a flap (202) pivotable from a seated position against the forward wall (102) of the housing (100) for blocking flow through the passage (110) to an unseated position in a spaced relation to the forward wall (102), permitting flow. A shoe (302) is carried at an inlet (112) to the flow passage (110) and a flexible planar flange (304) extends around the shoe (302) for engaging the surface (12) to be cleaned. A groove (310) within the shoe bottom surface forms a channel with the surface (12) to be cleaned for passage of debris and fluid flow through the channel.

Title: Process for manufacturing cylindrical sections from tubes, preferably of glass, and a device for performing the process
Inventor: KAVALLAR GUENTER
IPC: C03B33/085
Filed: 2000-02-04
Abstract: The process to which this invention relates is used to manufacture cylindrical sections from tubes, preferably of glass, for use in particular as syringe cylinders. The tubes are first withdrawn from the supply station and are then transferred individually to the processing station . There the tubes are held in such a manner that they can be moved axially forward and rotated about their axis, so that cylindrical sections can be sequentially cut from them by means of a laser. After each section is cut off, it is moved axially forward away from the tube. The opposing end surfaces of the tube and the section are simultaneously or serially melted to form a bulge or lip. Finally, the sections are conducted by means of guiding devices to the transportation unit, which is equipped with receptacles that have low heat-conducting properties, so as to avoid the occurrence of any mechanical stress in the sections as they cool, while the tube is moved forward for removal of the next section.
