Title: Electric typewriter with platen turned by stepping motor - has manual switch for interrupting programme controlled motor operation
Inventor: BERTRAM RALF
IPC: B41J11/38
Filed: 1976-12-24

Title: Secure data transmission with redundancy testing - involves counting number of distorted bits and signal delivery is stopped when it exceeds given valve
Inventor: EICHLER PETER
IPC: H04L1/00
Filed: 1977-02-12
Abstract: A cycle and block synchronisation during signal evaluation is completed, and an interference criterion appears. This criterion is derived from the deviation of at least one pulse or bit parameter, such as amplitude, shape, frequency spectrum and energy content, from an expected pattern. The duration of interference is tested and the number of affected bits is continuously counted and stored. When the stored number of affected bits reaches or exceeds a predictable value, delivery of signals is blocked.

Title: Electronic comparative capacitance measurement device - produces integrated pulse width modulated capacitance proportional signals using monostable circuits (NL 7.8.78)
Inventor: RIPKA KARL WOLFGANG DIPL ING
IPC: G01R27/26
Filed: 1978-02-03
Abstract: An electronic capacitance measurement device, esp. for measurement of capacitances of the order of picofarads, converts capacitance variations into proportional current or voltage variations. A monostable multivibrator triggered by rectangular pulses is used for pulse shaping, and each capacitance to be measured is connected as part of the charging circuit of a monostable flip-flop whose pulse width corresp. to the capacitance. The device is used for comparative measurement of two variable capacitances varying with physical parameters such as temp., press., fluid volume etc. One capacitance varies with the parameter being measured, the other compensates unwanted effects. The flip-flops are triggered by an alternating voltage of extremely stable frequency. The pulse duration modulated output signals are integrated and fed to an indicator.

Title: Pull=out dispenser for sheets or lengths e.g. of absorbent paper - has narrow dispensing aperture through which a polyethylene film starting sheet is pulled, entraining first paper sheet
Inventor: WAHL KENT ROBERT
IPC: A47K10/32
Filed: 1978-03-11
Abstract: Starting installation for a package dispensing sheets or webs by pulling them out of a constricted dispensing outlet, contains a starting sheet which is less porous than the sheets actually to be dispensed. The first sheet issuing from, i.e. being pulled out of, the package is arranged with the less porous starting sheet in such a way that the act of pulling it out causes part of the starting sheet to pass through the dispensing outlet. This part is long enough to enable a user to grip it comfortably and easily, the first sheet being pulled out with it. The starting sheet is suitably a piece of polyethylene film. The article is used for dispensing e.g. interleaved sheets of absorbent paper prods.
