Abstract: ABSTRACT           A releasable ski binding comprising separable binding parts including clamping members for releasably securing a ski boot to a ski and responsive to a predetermined force applied to the binding parts for a predetermined period of time for separating the binding parts.  The clamping members are coupled in frictional engagement, one of the members being movable at a controllable rate of movement in response to a movement of the binding parts.  With a predetermined force applied for the predetermined period of time, the one movable member effects a complete and substantially instantaneous release of all clamping forces from the binding parts.

Abstract: Process for the preparation of phosphorus pentachloride Abstract:   The invention relates to a process for the preparation of highly pure phosphorus pentachloride in the form of a free-flowing crystalline powder by reaction of phosphorus trichloride with chlorine.  The reaction is carried out in two stages.  In the first stage, phosphorus trichloride is combined with 0.1 to 0.999 times the molar amount of chlorine at a temperature of O to 150°C, whilst stirring, and is thereby reacted to give a crystal sludge comprising phosphorus pentachloride and phosphorus trichloride.  In the second stage, this sludge is allowed to react with an excess of chlorine at O to 150°C to give phosphorus pentachloride.

Abstract: PRECIOUS METAL RECOVERY CARTRIDGE             AND METHOD              Abstract A cartridge housing (12) having a liquid inlet (14) at one end and an outlet (16) at the oppo-site end carries in an intermediate volume a spiral rolled exchange mass (18) of flexible, resilient, fibrous material forming a matrix that is self-sup-porting and non-reactive with the type of solutions with which the cartridge is intended to be used. Within the exchange mass is carried a dispersed array of finely divided particles of replacement metal (19), adhesively attached to the fibers.  At each end of the cartridge adjacent to the inlet and outlet is a cavity (20) communicating with a spiral end (38) of the ex-change mass, and the inlet cavity (20) houses an inlet nipple (26) that has a discharge opening (30) facing generally away from the spiral end face (38) of the mass.  As flow through the mass produces precipitated precious metal, the mass is able to flex and thereby avoid clogging.  Fiberglass is the preferred material for the exchange matrix.  For some solutions a filter mass (21) is mounted in the same cartridge housing downstream of the exchange mass (18) to filter out selected products in solution.

Abstract: ABSTRACT The invention concerns the laying of dust during the extraction of minerals by means of cutting drums during mining, preferably during underground coal-mining.  The liquid sprayed from nozzles on the drum is wholly or partly drawn back into the cutting drum, is mixed with fresh spraying liquid, and is used again for spraying.  This produces a curtain of spray which circulates closely around the cutting drum.  Selecting the negative pressure obtaining makes it possible to vary the spread of the curtain of spray within certain limits.  An advantageous cutting drum is disclosed whereby the spray ejected towards the working face is drawn back into the discharge end of the cutting drum, and at the surface thereof, for example in the vicinity of the helical vanes.

Abstract: ABSTRACT OF THE DISCLOSURE         Apparatus for testing strength of door frames, consisting of a sturdy set of relatively movable pressure plates made of a heavy gauge sheet metal, designed for easy insertion into the usual space between the door and frame jamb at a position directly above the area of the latch bolt, and an interconnecting drive mechanism to apply a balanced force between the door and the frame on the inside only.          Energy to drive the mechanism is supplied by the operator, using an ordinary drive socket and torque wrench with a modified scale that provides a direct indication of the force generated at the pressure plates.  Frame spreading is also read on another scale and indicates an inverse measure of frame strength.  Rotary motion from the wrench is converted to linear motion of the plates by means of a lever assembly which also multiplies the driving force to the high level required.  This door frame tester provides the user with an accurate high strength means for non-destructive testing of new and older door frames.
