Title: Labelling machine label feed mechanism - has antifriction pusher plate behind label stack with balls embedded between corrugations
IPC: B65C9/10
Filed: 1975-11-21
Abstract: The labelling machine has a label feed device in which a bundle of labels on edge is pushed forwards along a trough-shaped guide towards an application position. A pusher plate (16) moved along the trough behind the bundle can be swung upwards about a rail (14) alongside the trough so that the next bundle placed behind the first can be advanced without interruption. This pusher plate (16) is designed so that it does not lift the labels due to friction, when it is swung up. The plate is of corrugated construction, with balls (20) trapped between the corrugations (21) so that there is always air space between the plate and the labels. The corrugations thus form a cage for the balls.

Title: Wet treatment drum for hides - with axial partitions in one section angularly offset against partitions on next section
Inventor: HAGSPIEL WILHELM
IPC: C14C15/00
Filed: 1977-04-21
Abstract: A horizontal drum for the wet treatment of skins, hides or textile materials is divided by one or more partitions at right angles to the axis into treatment sections. The latter are subdivided by partitions parallel to the axis into treatment chambers, each with its own door for charging and discharging. The axially parallel partitions of each section are offset relative to those of the adjoining sections by an angle which depends on the number of sections and the number of chambers in each section. When discharging the chamber one-by-one, the drum motor requires only one-third of the starting torque, compared with a conventional drum, for the last movement to discharge the last chamber. Slipping of a Vee belt drive or failure of the hydraulic couplings can thus be eliminated.

Title: X=ray generator circuit with selector operating computer - allowing operation by prescribed values for milliamps per second value or exposure time
Inventor: HERMEYER BERND DIPL ING
IPC: H05G1/38
Filed: 1977-05-13
Abstract: A control system makes it possible to operate an X-ray generator at choice, via an mAs switch or a time switch, so that alterations in tension or in the capacity of the tube due to changeover to a different size of focal spot, as well as difference in exposure time, etc. can be accommodated. A unit puts in a value corresponding to the exposure time or to the mAs-product, and there are displays for the mAs-product and for the exposure time. The one display is controlled direct, whilst the other is controlled by a computer which signals the value to be displayed with regard to the directly indicated value of the exposure tension and the load-supporting vapacity of the X-ray tube. There is a switching circuit for ending the exposure when the predetermined mAs-product or the exposure time has been reached. A selector operates the computer so that the mAs-product is calculated from the prescribed exposure time, and the exposure time is calculated from the prescribed mAs-product. The values for the indicators and for the switch can be put in directly or via the computer.
