Title: Insulated resilient sports hall floor - has load distribution panels on spaced spring boards and elastic strips
Inventor: MARTSCH HANS GEORG
IPC: E04F15/22
Filed: 1975-11-14
Abstract: Floor, which combines insulating and elastic qualities, is for installations in sports halls, and similar buildings. It incorporates a substructure, partly system-elastic and partly layer-elastic, set between a top layer and an insulating foil sheet lying on the base. There are load-distribution panels below the top layer, lying on spring boards which run parallel to each other at intervals. These can be combined with elastic overlay and underlay strips, made of plastic. there may be lower spring boards of greater thickness than the upper ones. The elastic overlay and underlay strips may be divided into sections. This provides effective punctiform and surface elasticity, while wear on the under substructure boards is reduced, and it is self-ventilating.
Patent DE-2551387-A1 (DE)
Title: Adaptive delta modulation signal transmission circuit - is controlled by frame cycle and transmits signal of either positive or negative polarity
IPC: H03M3/02
Filed: 1975-11-15
Abstract: The signal polarity depends on whether the signal value is greater or smaller than the estimated value. Depending on preceding history of transmitted polarities, a logic unit (4) selects one of 2n current sources (5), n sources for each polarity, and connects it to an integrator (6) which guides the estimated signals value towards the input signal value. A reference voltage (7) is derived from the amplitude envelope and from the frequency of zero crossings of the estimated signal, which multiplicatively controls the 2n current sources (5), realised as voltage controlled current sources. Increments of the n positive and n negative current sources follow a linear, or an exponential or any other characteristic.
