Abstract: An optical system and method for digitizing a last or other irregularly shaped article comprises a laser device fixed on a base directing a light beam at a last supported for rotation about an axis, perpendicular to which the light beam is directed. Two cameras are fixed to the base, one at each side of the laser device, and each comprises an array of cells for detecting the point of incidence of the light beam on the last surface. As the last is rotated, the point of incidence varies in relation to a datum, e.g. the axis of rotation, and the point maximum intensity of illumination on the array of cells will vary across the array accordingly. By a correlating technique, the distance of the point of incidence from the datum can be determined according to the point of maximum intensity of the array.

Abstract: A hypodermic syringe having a cannula with a point that can be safely destroyed and stored. A portion of the cannula is disposed within a hollow housing that has a reel fitted therein and a portion extends externally therefrom through an aperture in which it is slidably received. A portion of the cannula is disposed in the reel whereby to enable a user to turn the reel, wrap the cannula around the reel to destroy and store it. When the point is fully retracted into the housing, the point can snap against the inside of the housing and provides sensory indications that it is fully withdrawn. The axis of rotation of the reel is at right angles to the cannula.

Abstract: A disposable device for the use, destruction and storage of a cannula useful for placement in blood vessels. The device includes a housing for the cannula with apertures through which the cannula extends and is slidably disposed. The cannula is fixedly disposed through a reel that is fitted in a cavity in the housing. The reel has an axis of rotation at right angles to the cannula and turning the reel wraps the cannula around the reel to deform, destroy and store it. The points of the cannula will be withdrawn into the housing through the apertures. When the points are fully withdrawn they will snap against the inside of the housing to provide sensory indications that the device can be handled safely.

Abstract: An improved razor head for attachment to a razor handle comprising a pair of inwardly directed fingers for engagement with a pivotable razor cartridge is provided with a single button for attachment of the razor head to the cartridge. The button is positioned for ease of operation by the thumb when the razor handle is grasped by the user and pressure on the button is effective to move the fingers linearly outwardly along a line parallel to the cartridge width dimension, or razor edge. The fingers are locked in the outward, or open, position after release of the pressure on the button and are returned to the inward or engaging position through contact of the cartridge with a cam follower on the razor head.

Abstract: A belt for securing sensing electrodes to the chest of an infant afflicted with Apnea. The belt comprises an elongated band of fabric of sufficient length to encircle and to be fastened around the chest of the infant. The band has an inner side, an outer side and two ends. A tunnel is disposed on the inner side of the band and is adapted to removably receive and house wires for connecting sensing electrodes to an Apnea monitor. Two ports are disposed at the ends of the tunnel and arranged to allow wires to extend from the band and be connected to the monitor. Another port is disposed centrally of the band and arranged to form a port and allow wires to extend from the band to connect to the sensing electrodes. To fasten the belt to the infant, an interrelatable, two component, adjustable fastener is disposed on each end of the band.

Abstract: A display device comprising a peg board and a rod extending therefrom for supporting a plurality of aligned items is provided with an anti-pilferage fixture. The anti-pilferage fixture is formed of a cage-like structure supported from the peg board and disposed about the aligned items, which inhibits movement of no more than a predetermined number of items outwardly from the free end of the rod in a single movement, thereby providing a deterrent to the pilfering of a large number of items from the display.

An opening is provided extending through the brush element to the bristles which aligns with an opening in the elongated handle entering into a gel retainer in the handle, when the handle is positioned at right angles to the brush element. A flange disposed on the brush element is effective to seal off the opening in the elongated handle with the elongated handle positioned adjacent the brush element.

Abstract: A machine for progressively roughing marginal portions of shoe bottoms comprising a shoe support (18) having toe support means (470) and a heel support arrangement including two sets of clamps (390, 392), one set (392) of which serves also as sensing means for sensing, by engagement with an off-set portion of the shoe last whether the shoe thus supported is a left or a right. An inductance sensing device (610) associated with the second set of clamps (392) supplies a signal to control means of the machine, the signal being dependent upon whether the shoe is a left or a right. The control means ensures that, in the operation of the machine, a roughing operation is carried out on the shoe bottom in such a manner that the inside waist region of the shoe bottom is traversed always in the same directiion, regardless of whether the shoe is a left or a right (and of course similarly the outside waist region is consistently operated upon).

Abstract: A container for dispensing a cosmetic product such as a deodorant in stick form comprises a one piece tubular body open at the top having a platform disposed therein movably by means of a dial shaft threaded into the platform.
