Abstract: ABSTRACT OF THE DISCLOSURE      Improvements in and relating to Data Processing Interpolating apparatus is provided for more accurately determining the peak position of a function, particularly a cross-correlation function derived from two related flow signals fed to an overloading counter correlation flowmeter, whereby the peak position is indicated by a set of signals corresponding to quantised values of a perimeter and the apparatus interpolates the peak position from selected signals of the set.  The preferred method of operation comprises computing for each of the signals an average of the quantised values of the parameter corresponding to that signal, and summing a predetermined number of these average values to obtain an indication of an interpolated value of the peak position.           Various output circuits are provided for flowmeter appli-cations to produce an output which is proportional to flow rate.

Abstract: ABSTRACT OF THE DISCLOSURE    An induction heating apparatus of the invention is provided with a pair of inversely parallel connected thyristors which receives power from a low frequency energy source.  Depending on the polarity of the source voltage, one of the thyristors is triggered into con-duction by a control pulse generated in delayed response to a sensed forward bias potential at its anode for the purpose of supplying a forward current to a com-mutating circuit which is tuned to a high frequency in the ultrasonic range, whereupon a backward current is generated.  The backward current is commutated through the other thyristor to complete a high frequency oscil-lation.  A detector is provided to detect when the magnitude of the backward commutating current reaches a predetermined value for the purpose of terminating the trigger control pulse.  The control pulses are sup-plied simultaneously to both thyristors through a pulse transformer which upon termination of the control pulse generates a counterelectromotive force which negatively biases the thyristor which has been conducting during the first half-cycle of each complete oscillation to reduce its turn-off time.

IPC: A63C9/084
Filed: 1979-08-09
Granted: 1982-06-15
Abstract: ABSTRACT OF THE DISCLOSURE A ski safety binding of the type in which a sole clamp is pivotally mounted about a  transverse pivot axis on a base plate and is retained in a closed position for clamping a ski boot by means of a spring loaded latch device. During safety release the sole clamp is able to pivot upwardly about the transverse axis to overcome the latching force. To allow the sole clamp to be readily opened by hand a pivotable hand opening lever is provided for relieving the spring loading of the latch device.          The latch device features a latch projection carried at one end of a pivoted latch lever which is spring loaded by a coil spring carried by the hand opening lever. The force of the spring is transmitted to the latch lever via a bar-like extension of a spring abutment which is dis-placeably arranged relative to the hand opening lever and which is pivotally connected to the latch lever about a further transverse pivot axis which defines the pivot axis for the hand opening lever. The force of the latch spring is reacted by a second latch device which constrains the position of the hand opening lever relative to the latch lever. On disengaging the second latch device by pulling the hand opening lever upwardly a sufficient mechanical advantage is available to readily overcome the force of the latch spring and the hand opening lever is free to move in a direction such that the force of the latch spring is no longer applied to the latch lever.

Title: Communications system with repeater  stations
Inventor: BUEHRLE WILLIAM B
IPC: H04Q9/00
Filed: 1979-12-04
Granted: 1982-06-01
Abstract: ABSTRACT   A radio communication system includes a polling central station and a number of remote stations.  Each remote station is identified by a unique address transmitted from the central station preceding a message intended for such remote station.  Each of the remote stations also may be programmed to respond to the address of a "partner" station in addition to responding to it's own address.  The "partner" station address is employed whenever one of the remote stations is located such that a transmission link problem exists between such station and the central station polling station.  When this condition exists, the station which has difficulty communicating directly with the central station is provided with a new address and no longer is responsive to the address of messages transmitted to it from the central station. Another remote station, having a better communications link between it and the central station, then is optionally programmed to respond to the address of its "partner" station and translates that address to the new address, which precedes the relaying or retransmission of the message to the partner station.  Similarly, messages from the partner station are transmitted to the relaying station, preceded by the new address and the relaying station translates the new address to the original or normal address of the partner station for retransmission to the central polling station.          Thus, different ones of the remote stations optionally may be used as relaying stations as needed in the implementation of the system, without requiring any changes whatsoever in the operation of the central polling station.

Abstract: SHAPING OF COILS       ABSTRACT OF THE DISCLOSURE The invention relates to the shaping of coils in the form of helically wound bare wires, particularly for use in "smooth top" cookers.  In so-called "smooth top" cookers an unprotected helically coiled wire is secured in a electrically and thermally insulative base to tran-smit heat primarily by radiation through a smooth top, normally of glass ceramic.  The coils used in such cookers are normally very springy and require careful securement if they are not to free themselves during the life of the cooker.  According to the present invention, the stresses which cause this springy resilience can be relieved by holding a coil in a groove of the desired configuration and heating it, normally to the annealing temperature of the material of the coil.  The subsequently cooled coil will then hold its shape and not tend to straighten, and can be more easily held in place in the cooker.

Abstract: ABSTRACT           Apparatus for conditioning the hearing of a patient is disclosed.  A signal level detector establishes whether an incoming audio signal is above or below a threshold level to gate the audio signal to one or other of two parallel channels.  The first channel has a frequency response curve in which high frequencies are suppresses and this is the channel used when the audio signal is below the threshold. The other channel has a frequency response curve in which low frequencies are suppressed and this is the channel used when the audio signal exceeds the threshold.  Two parallel output stages are provided, one including an electromechanical vibrator which is placed on the patient's skull and the other including earphones worn by the patient.  A time delay module is also provided so that when switching from the one channel to the other channel occurs, the vibrator is switched to the other channel a predetermined time before the earphones which causes the conduction of vibrations through the patient's skull to precede the conduction of sound waves in air. This has the effect of preparing the patient for receipt of the air sound waves and can improve his speech.
