Abstract: A manually operated pneumatic rock drill positioner for mining shaft wall boring, said positioner comprising: an articulated boom having one end for releasable coupling to a mobile ground platform and another end opposite said one end thereof; a rigid elongated drill turret defining a main body with an exposed outer wall, an inner wall opposite said outer wall, and first side edge wall and second side edge wall opposite said first side edge wall, and first end and second end opposite said first end, a lengthwise rail member integrally mounted to said turret outer wall; a carriage slidingly engaging said rail member, said carriage for slidingly carrying a pneumatic drill head over said turret exposed outer wall for reciprocating motion thereof between said first end and second end thereof; drive means for power actuating said carriage sliding motion along said rail member; a cradle member releasably anchored to said boom another end and defining a well sized and shaped for releasable engagement by an intermedi

Abstract: Described herein are various embodiments of systems, methods, and apparatus that allow a user to share data, such as one or more files from within an application with one or more other (not necessarily co-located) computing devices using a gesture-based sharing function. In a particular example, systems, methods, and apparatus described herein may be used to share graphical representations of chemical structures within a chemical structure rendering application between two or more user devices. By offering a user a quick and visually intuitive option for sharing a file with other user(s) without exiting a current application, the systems, methods, and apparatus described herein provide efficient and engaging tools for sharing work product in real time between two or more users.

Abstract: Disclosed is a method and apparatus for positioning and assembly of two or more parts wherein at least one of which is of a creep sensitive material. The method and apparatus enable very precise positioning of parts during assembly by holding a rough alignment with free play permitting finer alignment. Creep resistant annular inserts are molded into the part and provided with flow apertures to conduct plastic material into the annular insert bore. A spindle defined the geometry of a centering hole within the bore during molding. The annular inserts are operable as compression limiters to prevent deformation of the creep sensitive material under the action of heat or tightening stresses.

Abstract: Disclosed is a heat transfer module (3) for battery cells includes a plastic frame (4) having a supply conduit and an exhaust conduit (13b) for a heat transfer fluid. Two heat transfer members (12a, 12b) contacting a respective battery cell. The heat transfer members (12a, 12b) are sealingly attached to opposite faces of the frame (4), and at least one heat transfer channel (15) formed between the frame (4) and one of the heat transfer members (12b) transporting the heat transfer fluid from the supply conduit to the exhaust conduit (13b). Also disclosed is a battery assembly having a plurality of such heat transfer modules (3).

Abstract: A spray gun for dispensing two liquids under pressure independently from one another or both simultaneously to form a mixture. The spray gun has a barrel in which are independently displaced two valves which are each spring biased to a closed position. A pair of trigger levers are pivotally secured to a single handle of the spray gun and independently or simultaneously actuable by the fingers of a single hand of the user person whereby to dispense two fluids independently or simultaneously. The valves are mounted coaxially within one another within the barrel of the gun. The valve assembly is easily removed from the barrel of the gun to facilitate servicing and assembly.

Abstract: A head cooling device for mounting over a person's head, generally within a headgear or a safety helmet. The device comprises: a housing, defining a main body enclosing a generally closed pocket, for containing ice cubes therein, a mouth, at one end of the main body, and an intermediate flooring, for supporting the ice cubes inside the pocket spacedly from the mouth. Thus, the flooring remains spaced at all times from the scalp by a spacing gap. The flooring is bored at its periphery, for enabling water droplets from the melting ice cubes to escape one at a time from the pocket, freely through the spacing gap and toward and against the person's head scalp. Flexible bands are used, integral to the housing, for releasably anchoring the housing to the head in generally overhanging fashion.

Abstract: A balancing apparatus having a surf board, an upstanding support post and a main universal joint connected in-between the bottom of the surf board and the top of the support post. The surf board can be tilted relatively to the support post about two different axes passing through the center of the support post.
