Abstract: There is disclosed a boot with an internal forced air circulation system and an inflatable lining. The boot can also be used to circulate air through protective clothing and can have a footwarmer mechanism. The boot is ideally suited for skiing. Three alterenative mechanisms are disclosed, all of which are operated by the normal movements of the person wearing the boot. The footwarmer mechanism is mounted entirely as an insert for the outer shoe or boot and is most preferably removably mounted on a bottom plate that is secured as an insert to the lower sole portion to the inner shoe. A heat engine, which is a compressible fluid engine operating on a quasi-Carnot cycle, can be used as the footwarmer. For this purpose the heat engine includes a compressor for compressing a gas, a condenser for condensing the gas into a liquid, an expansion and evaporator zone for expanding liquified gas into a gas and a return line to cycle the expanded gas to the compressor. Flow reversing valves can be provided whereby the heat engine can be reversed, to heat the shoe in the winter, and cool the shoe in the summer. In another embodiment, the foot warmer mechanism includes an electrical resistance heater, an electrical generator, a mechanical transducer to translate vertical movements of the wearer's heel into uni-directional rotational movement of a flywheel, and a gear box mechanically coupling the flywheel to the electrical generator. Optional features include a rechargeable storage battery and a radio transmitter for generating a signal useful for locating the wearer. In another embodiment, the footwarmer mechanism can be a pair of sole plates which are in sliding frictional engagement and generate frictional heat.

Title: Dual conversion force motor
Inventor: MOHLER DAVID B
IPC: H02K33/16
Filed: 1989-04-03
Granted: 1992-10-27
Abstract: Abstract of the Disclosure Disclosed is a dual working airgap force motor.  A centrally located stator includes two toroidally shaped electromagnets wherein the axis of the stator coincides with the axis of the toroids, each toroidal coil is separated from the other toroidal coil by an axial distance. Toroidal permanent magnets are also mounted preferably inside the toroidal electromagnet coils and also spaced apart in an axial direction.  The permanent magnets generate a flux flow in opposite axial directions whereas, upon energization, the toroidal coils generate flux flow in the same axial direction at a given radial position.  Two armatures are located on an output shaft, in a preferred embodiment at either end of the stator, and each armature is spaced apart from the stator by inner and outer axial airgaps. Energization of the coils with current causes a greater flux flow across the inner and outer airgaps at one end than is caused through the inner and outer airgaps at the other end tending to reduce the airgap at the end with the largest flux flow consequently causing movement of the respective armatures and the output shaft upon which they are mounted.

Abstract: The present invention relates to a method and apparatus for separating gas by a  pump from the medium being pumped, which method and apparatus are especially suitable in pumping the gaseous fibre suspensions in the wood processing industry. In the apparatuses of the prior art used for a corresponding purpose the trouble has been not the separation of the gas from the medium, but guiding the gas out of the pump in such a way that no solids would enter the gas discharge system, because gradually the gas discharge system and a vacuum pump possibly in it would clog and this would result in reparations requiring a lot of time and this again in expensive stops at the mill. The method and apparatus in accordance with the present invention eliminate or minimize the above described defect in such a way that rear vanes (11) of the pump or the members operating together with them are arranged in such a way that they either direct the flow of the medium, generated by the combined effect of forces with different directions and different intensities directed at the medium in the space behind the impeller in the vane gaps of said rear vanes, past gas discharge opening (12) in the rear wall of the pump or they slow down said flow so that its extension to said gas discharge opening (12) is prevented.

Abstract: The present invention provides a method capable of lining a multibranch piping with a coating material within the pot life of the coating material without leaving uncoated area or excessive repeated coating.          Lining for a main pipe is performed by pouring the coating material into the main pipe from an end portion of the pipe, and lining for branch pipes is effected by the feed of the coating material and air for each of the branch pipes.  A completed time point of lining in each branch pipe is detected by any of the following methods:          (A)  A method wherein the time required for lining a branch pipe is estimated in advance and upon lapse of the estimated time it is judged that the lining for the branch pipe was completed.          (B)  A method wherein a change in gas pressure in the main pipe which occurs upon arrival of the coating material at the connection between a branch pipe and the main pipe under the feed of air is detected by a pressure gauge, whereupon it is judged that the lining for the branch pipe was completed.          (C)  A method wherein when the coating material fed from an end portion of one branch pipe was discharged from another branch pipe located in a position close to the one branch pipe, it is judged that the lining was completed.

Abstract: A hinged hatch assembly for the roof of a vehicle cab having an opening formed therein. The assembly includes a hatch which completely covers the opening when in a closed position. The hatch is connected to the roof of the vehicle cab by a pair of support arms. Each support arm contains a first and a second forked end whereby the first forked ends are pivotally attached by brackets to one side of the roof opening and the second forked ends are pivotally attached by brackets to the underside of the hatch. Sandwiched on each side of the brackets between the forked ends of the support arms are frictional elements which are spring loaded to impart a predetermined frictional force on the members. The frictional contact permits the hatch to be opened at various angles and at various positions relative to the plane of the roof and to remain in the desired position irrespective of any vibration or motion imparted into the vehicle. The hinged hatch roof assembly is capable of providing ventilation as well as serving as an escape route from the interior of the vehicle cab.
