Patent DE-3164677-D1 (DE)
Title: Method of controlling a heating apparatus and heating apparatus controlled by this method
Inventor: TROUILHET YVES
IPC: F24H9/20
Filed: 1981-04-14
Granted: 1984-08-16
Abstract: The apparatus comprises an accumulation block (2) heated by resistances (3). A fan (7) circulates air in a closed circuit through the block (2) and through an air-water heat exchanger (8). A regulator (14) measures the temperature of the water by means of a probe (15) and the air temperature by means of a probe (16) which is used for determining the water temperature. A synchronous servo motor (13) connected to the regulator (14) determines the position of an air distribution flap (11) as a function of the power required for heating the water by deviating a portion of the air stream through a deviation passage (10). When the flap (11) closes completely said passage, it simultaneously closes a switch (18) for supplying the heating resistances (3) of the block (2).
Patent DE-3169636-D1 (DE)
Title: Receivers suitable for use in remotely-operable switching devices and data transmission systems
Inventor: SKINNER MICHAEL JOHN
IPC: H04B3/54
Filed: 1981-02-12
Granted: 1985-05-09
Abstract: A receiver, for receiving a signal comprising a carrier signal modulated with a digital signal, comprises means for demodulating the received signal to produce an output signal which contains the digital signal. Because of repeated filtering, the digital signal is typically in the form of an approximately sinusoidal signal, which has a component whose frequency is equal to half the basic bit rate of the digital signal: because of noise, this component is subject to considerable timing jitter. To overcome this, the output signal is digitized and applied to a digital correlator, where it is correlated with a reference signal whose frequency is also equal to half the basic bit rate of the digital signal. The reference signal is preferably derived from a phase-locked loop locked to the carrier frequency. The correlator, which is constituted by a microprocessor, determines the instants of time which most nearly coincide with the mean-level crossing points of said component (which instants correspond to transitions between one bit of the digital signal and the next), and also determines successive bit values on the basis of the coincidence determination. The receiver can be used to receive mains-borne signals, i.e. signals transmitted over an electrical power supply network, or radio broadcast signals. The received signals employ at least one of two or more carrier frequencies derived from a common oscillator, and the receiver includes a phase locked loop capable of locking a local oscillator in the receiver to whichever of the carrier frequencies is being received.

Patent DE-3263477-D1 (DE)
Title: Rolling mills
Inventor: GILVAR MARTIN
IPC: B21B41/00
Filed: 1982-02-12
Granted: 1985-06-20
Abstract: In a rolling mill wherein hot rolled rod is directed along a downwardly curved path into a vertical laying head which forms the rod into a series of rings, a method of and apparatus for propelling the rod through the laying head. The rod is passed between a pair of adjustable driven pinch rolls located in advance of the downwardly curved path. An initial closing force is exerted on the pinch rolls to establish an initial parting prior to entry of a rod front end therebetween. The initial parting is sized to produce at least some rod deformation while providing a driving relationship between the pinch rolls and the rod. The initial closing force is greater than the momentary surge in separating force accompanying impact of a rod front end with the pinch rolls. The initial parting is maintained until the rod front end has negotiated the downwardly curved path and has passed through the laying head, at which time the initial closing force is released. The pinch rolls can then either be opened completely to allow the rod to continue running freely therebetween, or the initial closing force can be replaced by a lower secondary closing force which allows the rod to push the pinch rolls apart to a secondary parting. The secondary parting continues the driving relationship between the pinch rolls and the rod, without any accompanying rod deformation.
