In a transmission of the type which includes a main transmission mechanism equipped with gear trains of a plurality of transmission stages disposed between an input shaft capable of being connected to a crank shaft of an engine and an output shaft parallel to the input shaft and a sub-transmission mechanism transmitting the driving force from the input shaft to a driven gear of the output shaft vi...

The binding has a base plate (1) carrying a toe connection means (2), a heel connection means (3) and a brake (20) which functions automatically when a ski boot (4) is released from the binding, the brake comprising a generally V-shaped member of resilient material, the lower part of which provides brake arms (22) extending rearwardly or rearwardly-downwardly respectively at each side of the ski (...

The base plate (1) of a safety ski binding carries toe and heel connection means (2,3) for a ski boot (4) and is fixedly mounted at or near one end to the ski (30), e.g. by means of screws (36), and is also displaceably mounted on the ski at some other point, especially by means of a pin (37) which is slidable and rotatable in a bushing (41) of a slide member (39) so as to allow bowing of the ski....

Circuitry for use in a hand-held electronic probe for passing high frequency current through malignant eye tissue of livestock or other tissue such as warts includes a thermistor in a probe tip that contacts the tissue, producing a voltage that controls a voltage controlled oscillator which drives an audio transducer. If, during treatment, the probe tip is held against the malignant tissue with su...

A quick connect fitting for tubing which can be inserted into a pre-assembled fitting where it will become sealed and locked against pull-out. A main fitting body has an open-ended recess in which is located a movable piston to seal against the body and an inserted tube. The piston wedges over a conical extension on a sealing gland retained by a snap-on cap, the gland and the cap having complement...

The locations of defects in flat glass (1) are detected during conveyance through a detection station where the glass is scanned by a radiation beam (11). The beam sweeps transversely across the path of the glass through a distance in excess of the glass width so that the beam sweeps through both side edges. Beam deflection occurs when the beam encounters a side edge boundary of the glass (1) and ...

A controller including a servo to time movement of an animated character with audible sounds reproduced in synchronism with control signals for the servo. A slippable friction drive also makes it permissible to interrupt movement of the character for any period of time. After such an interruption is terminated, the servo and friction drive return the movement of the character to a normal phase and...

A cotton candy making apparatus includes a hollow rotary member to be rotated, the rotary member being provided with a supply port for supplying sugar to the interior thereof and path for delivering molten sugar to a peripheral edge of the rotary member, a heating device located below the rotary member to heat the rotary member and hence heat and melt sugar in the rotary member, a fan for producin...

A guidance method and system for an automotive vehicle which switches from an electronic navigational signal method to a dead reckoning method when any of the field strengths of three navigational electromagnetic wave signals drops below a predetermined lower limit or vice versa when the field strengths of the three navigational electromagnetic wave signals all exceed the lower limit. Therefore, e...

A curable, storage-stable and solventless single component sealant for pneumatic tires having as its essential sealant functioning components a liquid low molecular weight hydroxy terminated polybutadiene diol, an antioxidant, a polymeric isocyanate, and, a polyurethane catalyst; this sealant can be blended with a sealant optimizing amount of a masterbatch.

Porous, cross-linked polymeric materials comprising hydrocarbon residues can be sulphonated to produce sulphonated polymers which are able to absorb large volumes of ionic solutions and also act as ion-exchange resins.
