Abstract: A monocrystal rod utilized for producing the semiconductor device or solar cell includes a neck section, a main rod section and a shoulder section. The neck section is smaller in diameter than a seed crystal. The main rod section is formed integrally with the neck section and is larger in diameter than the neck section. The shoulder section is tapered for linking the neck section to the main rod section. The main rod section has a stopper section at the top portion of the main rod section, and the stopper section is larger than the main rod section.Also, an apparatus for preparing the monocrystal rod has a safety member for supporting upward the stopper section of the falling monocrystal rod.Further, a method of preparing the monocrystal rod includes the steps as follows. The seed crystal is pulled out from a melt in a crucible while rotating it.

Abstract: A hand-held labeler, particularly a labeler employing a thermographic print head, utilizes improved control circuitry for accurately sensing the position of the web and controlling the operation of the print head in order accurately to control the position of the imprints on the web. When a motor is used to advance the web, the control system is operative to control the operation and speed of the web advancing motor.

Abstract: A hand held labeler having an optical reader attached thereto whereby an encoded article may be scanned to provide information to the labeler. The information may be used to set the print head of the labeler.

Abstract: The invention relates to a device for attaching adhesive labels to objects comprising a rotatably mounted tubular labelling arm driven by a motor and having a suction head disposed at its free end, this suction head being directly connected via the tubular labelling arm to a vacuum source for the purpose of drawing a label by suction onto the suction head. In order to be able to use such a device, which has a high operating speed, as universally as possible, i.e. for labelling the most varied types of object, the tubular labelling arm bearing the suction head is designed to be bendably elastic and rotate in a single direction of rotation.

Abstract: The invention concerns a labeling machine for bottles that are to have one or more labels applied to them in a position determined by a specific indication on the bottle. Before the first label is applied, the bottles, which are secured between a rotating plate and a rotating head, are probed for the indication and rotated by an electric motor. The rotation from the motor is introduced through one input of a differential gear. Rotations derived from an invariable labeling program are introduced through the other input. The bottles can accordingly be positioned in the desired orientation without being loosened between the rotating plate and rotating head and without using a frictional clutch or gearshift.

Abstract: Automatic label applying apparatus comprises a conveyor for moving packages to a weigh scale and from thence to a label application station where a reciprocably movable vacuum type heated label applicator receives an appropriately printed label from a label issuing means and applies it to the appropriate package. A vacuum system connected to the label applicator holds the label thereon and also operates a pneumatic cylinder for a lock-out arm to prevent the heated label applicator from making contact with and burning a package when the vacuum system senses that no label is present. An electronic control system, including a photocell for sensing if a package is at the station and also including a limit switch actuated by the lock-out arm (and therefore indicative of the presence or absence of a label), operates to stop the conveyor after a predetermined interval of time in the event that a package is present at the station but no label is available to the label applicator.
