Title: Saw assembly with floating bearing for worm drive and motor shaft
Filed: 2012-09-25
Abstract: A saw assembly includes a housing, a motor, a worm gear, and a drive member. The housing defines an interior space. The motor is positioned in the housing and has a motor shaft, the motor being configured to rotate the motor shaft about a first axis. The worm gear is positioned in the housing and has a worm gear shaft. Rotation of the motor shaft causes rotation of the worm gear shaft. The drive member is operatively coupled to the worm gear. Rotation of the worm gear shaft causes movement of the drive member in a repeating pattern. The worm gear shaft includes a bore structure defining a blind bore and an opening leading to the blind bore. The bore structure defines a set of internal threads that are spaced apart from the opening. The motor shaft includes a set of external threads.

Title: A flowing-water driveable turbine assembly
Filed: 2012-11-13
Abstract: A flowing-water driveable turbine assembly 4 for location in river or sea areas comprises a turbine support 6 with positive buoyancy in water. The support includes fixed buoyant material (112, figure 11) arranged to form a cradle for a ballast tank (114, figure 11). The turbine support 6 has an anchoring system 8 which may comprise four or more tethers. The buoyancy device may be shaped so that hydrodynamic drag associated with downwards movement is greater than the drag associated with upwards movement. The positive buoyancy of the turbine assembly holds the turbine support 6 and the turbine 10 to a position of floating equilibrium against a downward force of the anchoring system 8. There may be a duct around each turbine for directing water through the turbine to generate power from water flow, and a winch for submerging the turbine assembly or parts thereof.

Title: Method for operating a monovalent alternative absorption heating installation
Inventor: HEIMBACH PAUL DIPL ING
IPC: F24H4/02
Filed: 1981-07-13
Granted: 1984-10-18
Abstract: A method of operating a monovalent alternative absorption heating plant an apparatus operated by this method in which above a predetermined ambient temperature, the system is operated in a heat pump mode and at lower temperatures, in a direct heating mode. The system uses a coolant (refrigerant) circulation path in which the coolant is driven out of a solvent enriched with the coolant, is liquefied, is vaporized by heat exchange with the environment and is absorbed by coolant-poor solvent. The system also has a heat carrier circulation in which the heat carrier is heated by heat exchange with the continuing coolant and thus takes up absorption heat. According to the invention, in the direct heating mode, the heat carrier bypasses the coolant condenser and absorber and is passed through a heat exchanger separate from the coolant condenser and is there heated directly by combustion heat in a heat generator or by heat exchange with the coolant-poor solvent.

Title: Chlor-alkali cell with non-bleeding electrode
Inventor: SOLOMON FRANK
IPC: H01M4/88
Filed: 1981-10-28
Granted: 1988-03-24
Abstract: This disclosure is directed to a non-bleeding gas electrode for operation under the rigors of high current density and to the active layer thereof. This active layer is comprised of 60 to 90 weight percent high surface area, electroconductive carbon (with or without catalyst thereon), 10 to 40 weight percent particulate polytetrafluoroethylene (PTFE) and has pores sufficiently large to relieve internal hydrodynamic pressures thus preventing liquid being forced through the electrode wetproofing layer to the air side thereof. In addition such electrodes include a PTFE-containing wetproofing or backing layer secured on one side to said active layer and on the other side to a current distributor. The pores in both the active layer and the backing layer are controlled to relieve hydrodynamic pressures by coordinating the particle size of the pore former used to establish the pores in both said layers such that the repellancy of the backing layer to hot alkali exceeds the internal liquid pressures in the active layer. Of particular significance is the fact that the present electrode is non-bleeding when operated on air and preserves its low voltage at high current density over extended time periods without bleeding.
