Title: Insulation of outside walls of building with polyurethane foam - allowing covering with solid outer layer, and resistant to cracking
IPC: E04B1/76
Filed: 1975-04-18
Abstract: The insulation of the outside walls of a building comprises placing a structure 2a, 2c, 4,5) of intersecting vertical and horizontal beams, pref. metal wires, on the outside of the wall and fixing it temporarily at certain points. Polyurethane foam is then projected onto the wall, instantly setting in the foam of a rigid layer thick enough to embed the beams over part of their depth. A wire mesh-reinforced cardboard layer is then placed over and fixed to the beams, leaving a continuous air gap between the foam layer and cardboard layer. Finally a coating of water-repellent plaster, concrete, etc. is projected onto the cardboard layer with a thickness sufficient to provide a rigid outer coating. Pref. first some vertical beams are fixed edgewise onto the wall then other vertical beams are placed edgewise against the wall without fixing them, and the horizontal beam are interwoven with all the vertical beams so that the fixed vertical beams hold all the other beams in position.

Title: A=D converter for resolver - applies error signal during resolver supply half period and zero volts for subsequent half periods
Inventor: CARDONA GILBERT ANDRE
IPC: H03M1/00
Filed: 1976-03-30
Abstract: The a.d. converter is designed to provide in digital form the value of an angle from output signals from a resolver. The resolver being sensitive to the spatial orientation of an element. The convertor is of the double integration error signal type. It has an error signal processing circuit (10).

Title: Failure signalling circuit for cars trafficator lamps - uses AND=gate to detect open circuit and to switch=on fault signalling light
IPC: H05B37/03
Filed: 1976-06-24
Abstract: The signalling circuit indicates the failure of one of the two trafficator lights of a motor vehicle. The trafficator lights (1, 2) are each in series with a diode (5) shunted by a high-ohmic resistor (4). The junctions (A, B) between trafficator lights and diode/resistor networks are connected to the two inputs of a logic circuit (8) (AND circuit) that controls a signalling lamp (9) on the vehicle dashboard. If one trafficator light fails (open circuit), the voltage at its junction (e.g. A) is now determined by the resistor (4), the input to the AND circuit changes, and the fault signalling lamp lights.
