Title: Insulating panel eliminating any loss of heat.
IPC: F24F12/00
Filed: 1982-07-27
Abstract: Device enabling heat lost through a wall to be recovered and for it to be brought back into the enclosure from which it left by raising it to a usable temperature. The device is composed of a panel formed from three parallel walls 1, 2 and 3 which are closed by a frame over their entire perimeter, and is fixed hermetically to the wall it is desired to insulate and into which flows the air entering the premises.

IPC: C03B35/18
Filed: 1982-10-11
Abstract: A roller construction is described for use in glass bending apparatus employing an array of curved rods. A tubular sheath is rotatably mounted on a curved rod. The sheath comprises a tubular metal winding that is coaxial with the rod and a coaxial metal meshing adjacent either the inner or outer surface of the winding. Such a sheath provides both good torsional resistance and flexibility in the axial direction. When an array of such curved rods is used to define a cylindrical surface in glass bending apparatus, heated glass sheets may be bent on such array to conform their curvature to the surface defined by the rods.

Patent FR-2521289-A1 (FR)
Inventor: DOLL FRIEDHELM
IPC: G01F1/60
Filed: 1983-02-01
Abstract: The exciter coil (10), which generates a magnetic field in the tube of an inductive flow meter, is supplied by two electronic switches (11, 12) operated in push-pull, which are controlled by the output signal of a comparator (15). The switches (11, 12) are either opened or closed so that they have extremely low power dissipation. The exciter current is picked up from a current sensor (13) and supplied via a delay section (14) to the actual-value input of the comparator (15). At the setpoint input of the comparator (15), a setpoint signal of alternating positive and negative pulses is present. During a pulse of the setpoint signal, the switches (11, 12) are switched on and off numerous times because the operating threshold of the comparator (15) is exceeded in both directions. This produces an exciter current pulse on which a sawtooth is superimposed. The mean value of this pulse corresponds to the setpoint of the exciter current. The advantage lies in the low power consumption of the circuit and in being able to dispense with expensive cooling means.
