Title: Receive circuit for PBX subscriber - uses drop in voltage and current to represent binary states of signalling lines
Inventor: BLOSSFELDT DIETER ING GRAD
IPC: H04M9/00
Filed: 1980-09-25
Abstract: The receive circuit has a transistor measuring the voltage difference between binary signals sent from a shared device. The transistor is coupled to the signalling lines and its reference voltage is obtained from a capacitor connected via a reverse-biased Zener diode to the signalling line. The Zener diode's break-over voltage is chosen such that the sum of this voltage and the voltage drop across the transistor's base-emitter junction is at most equal to the drop in voltage that has occurred in describing the most-frequent binary state. The capacitor is disconnected from the signalling lines when the less-frequent binary state is transmitted using a drop in current on the signalling lines.

Title: Compensation method for diaphragm control in a single-lens reflex camera having interchangeable lenses, and interchangeable lens for use in conjunction with this method
Inventor: URANO FUMIO
IPC: G03B7/20
Filed: 1981-02-18
Abstract: In a single lens reflex camera with interchangeable lenses, in which the measurement of the subject contrast in the case of the largest diaphragm opening is carried out by the lens in the beam path on the image side at a location which does not correspond to the film plane, measurement errors which are produced by the difference between the greatest aperture value of the interchangeable lens mounted on the camera, the error in the brightness in the film plane, which error is assigned to this aperture value and depends on the individual optical characteristics of the interchangeable lens, and the error in the brightness which is based on the installation position of the light-sensitive element for measuring the subject contrast, which position differs from the location of the film plane, on the one hand, and the corresponding values or errors, on which the adjustment of the exposure measurement and exposure control is based, of a reference lens, on the other hand, are compensated by an electrical variable (e.g. a resistance value) generated in the respective interchangeable lens, which variable is fed, when the interchangeable lens is mounted on the camera body, to the exposure control circuit provided in the latter, and influences said circuit in such a way that the abovementioned difference is given consideration in controlling the diaphragm drive member. An additional displacement of the diaphragm blades owing to the design-induced delay time of the mechanical diaphragm drive system is compensated by a prior displacement which does not produce any change in the quantity of light incident on the lens (because, for example, the diaphragm blades still move in the range of the beam limitation set by the lens mount). <IMAGE>

Title: Marking device for the labels in a labelling station
IPC: B65C9/46
Filed: 1981-05-12
Abstract: The invention relates to a device and a method for marking a label. The device consists of a type field which is formed by one or more marking types and which, during marking, rolls on a stay in an extraction element carrying the label to be marked. Each marking type is formed by a plurality of tips which are assigned corresponding recesses in the stay. During the rolling of the type field on the label supported by the stay, the tips penetrate through the label and at the same time tear it locally, without particles being torn off from the label. In so far as the tips are wetted with ink, the tear edges are simultaneously inked, so that a permanently clearly visible marking remains, even on labels which are coated on the outside.
