Title: Fire-resistant building panels with mineral fibre core - bound to covering layers by protective layers of binding agent
Inventor: IHLEFELD KARL-HELMUT
IPC: E04B1/94
Filed: 1976-11-06
Abstract: Light wt. building panels, with good insulation to sound and heat and good resistance to fire, are made by binding a core of mineral fibres perpendicularly to the covering layers with a bonding agent consisting of an inorg. mat with good heat resistance or an org. mat. which cokes on heating and contains a high proportion of inorg. heat-resistant filler. Sufficient pref. 0.5-3 mm thick, bonding agent is employed so that, if the covering layer is burnt or falls off, the bonding agent seals off and protects the mineral fibres from the effect of heat. Used for partition walls. In the case of the burning or falling off of the covering layer in a fire, the arrangement of the fibres exposes thed fibre ends which are vulnerable to the effect of the heat. Formation of a protective layer by the bonding agent shields the ends of the fibres from the direct effect of the heat.

Title: Mechanical energy generating machine with rotary output - has swashplate within casing subjected partly to atmos. and partly to vacuum
Inventor: RUTARD PIERRE
IPC: F01B29/02
Filed: 1977-03-25
Abstract: A swashplate (16) is mounted on a spherical bearing (14). It drives an output shaft (12) through a crank and gear mechanism (40, 28, 28', 26, 26', 32).

Title: Interference signal suppression circuit - has filter combining integration between MTI filter and display and following threshold device
Inventor: GSTOETTNER GERMAN DIPL ING
IPC: G01S7/292
Filed: 1978-02-20
Abstract: The suppression circuit fulfills its task by the fact that of the receiver signals x(t) consisting of intelligence signals and interference signals only the interference signals are controlled irrespective of their level. Switching facilities are used to differentiate the corresponding pulse shapes. The value y(t) to which the interference signals are controlled is such that a constant false alarm rate is obtained. The pulse shapes may be differentiated by rating the time constants of a control loop (R, V, W, I) between the output of the MTI filter (7) and the threshold device (S).
