Patent DE-3100642-A1 (DE)
Title: Hollow block
IPC: E04B2/02
Filed: 1981-01-12
Abstract: In the case of a hollow block, insulating-material layers are arranged in spaces of the hollow block, parallel to two mutually opposite outer sides (4) of the hollow block, and are spaced apart from one another by at least one region (7, 8) which is penetrated by empty cavities (5). In order to configure the structure of such a hollow block in as uniform a manner as possible over the entire wall thickness and, nevertheless, to be able to use large-surface-area insulating-material layers, the regions (1, 2, 3) penetrated by insulating-material layers are also spaced apart, from the hollow-block outer sides (4) parallel to them, by such regions (6, 9) penetrated by empty cavities (5). Owing to the frequent alternation of comparatively narrow regions (1, 2, 3 and 6, 7, 8, 9) with insulating-material layers and without insulating-material layers, respectively, the structure of the hollow block is substantially standardised in terms of load-bearing capacity and insulating capacity and the effect of both types of cavities is brought to best advantage. <IMAGE>

Patent DE-3124423-A1 (DE)
Title: Device for producing and controlling an ignition process in internal combustion engines
IPC: F02P3/05
Filed: 1981-06-22
Abstract: This device for controlling an ignition process in internal combustion engines on the one hand permits an optimally high ignition voltage at low engine speed with an optimally adjustable, long combustion period of the ignition spark for cold starting in winter when the battery voltage is low, and on the other hand just as high an ignition voltage at high engine speed, despite the very short charging time of the ignition device. The advantages thereby obtained are more rapid starting despite low battery voltage in the winter and improved combustion of the petrol-air mixture, set lean for the sake of economy, at high engine speed. This is achieved by a recharging of the ignition coil, provided with lower inductance, which prolongs the combustion period of the ignition spark, the highest ignition voltage of the coil given this dimensioning also being obtained by a shorter charging process. This advantage of the shorter charging time has a favourable effect on the ignition voltage at higher engine speed. The lower inductance would have an adverse effect on the combustion period of the ignition spark, were an artificial prolonging of the combustion period of the ignition spark not achieved by controlled recharging at high frequency for an optimum period. The charging period when starting is brought forward by the control and therefore extended, thereby obtaining a high ignition voltage even when cold starting when the battery voltage is low.
