Abstract: IMPROVED STICKER PLACER APPARATUS                   Abstract of the Disclosure Improved sticker placer apparatus is described.  The apparatus includes plural, inclined sticker feed pockets for holding stickers simultaneously to be placed and vertically reciprocable placement arms, each being capable of displacing one sticker at a time from the mouth of the sticker pocket to a variable height of lumber indexed therebeneath, and each having a positive sticker capture device including a generally horizontal pivotable support arm for cradling the sticker thereabove, and a downwardly impinging pincer arm for urging the sticker downwardly throughout the placement cycle.  Each placement arm further has plural stops stop for halting the descent of the arm when the top of the lumber is reached, a slider link mechanism providing dwell time between the arm's downstroke and upstroke and a spring-tensioned rocker arm operable during the dwell time to pivot the support arm out from under the sticker when the associated stops are reached.  The individual slider link mechanisms selectably are extended and retracted by a single, common drive cylinder to reciprocate the associated placement arms.  Upstream stickers are retained by spring-tensioned pinch bars impinging on the face of the to-be-placed sticker.  Fully automatic, continuous operation of the apparatus is enabled by selectively openable and closeable feed gates located at the top of each feed pocket.

A record carrier (1) comprises a disc-shaped carrier provided with a radiation-sensitive layer (6) and is formed with a servo track (4). The servo track exhibits a track modulation in the form of a radial wobble whose frequency is modulated with a position-information signal (Fig. 2). Also revealed is an apparatus (Fig. 8) for forming the track pattern during manufacture of the record carrier (1). When an information signal (Vi) is recorded on the record carrier (1) and the recorded signal is read by means of a recording and/or read apparatus (Fig. 4) the position-information signal (Fig. 2) is recovered by means of an FM demodulator device (60) from variations in the scanning beam (55) which are produced by the track modulation. Moreover, a clock signal for the purpose of scanning-velocity control is recovered from said variation in the scanning beam. Furthermore, embodiments of the record carrier which are very suitable for recording EFM-modulated signals are described. (Figs. 1 and 2).

Abstract: A method to manufacture heat shrinkable plastics sleeves having uniform shrinking properties across the sleeve is achieved. The sleeves are manufactured from a cross-linking plastics material by extruding a tube of the material at a temperature below the cross-linking temperature of the plastics material. The tube is cut into individual sleeve pieces the lenght of which corresponds to the length of the finished sleeve. The sleeve pieces are heated to the cross-linking temperature while keeping the pieces uniformly supported so that no deformation in the wall of the sleeves can take place. After the heating step the sleeves are removed from the supporting elements and are expanded while cooling to the desired diameter by placing the tube as a loop around two or more rotation parallel rolls which are moved away from each other.
