Title: Servo-controlled RF band pass filter - has voltage tuned inductors switched to resonant oscillator mode and tracked to reference oscillator to determine control voltage
Inventor: LLOPIS MICHEL
IPC: H03L7/18
Filed: 1980-07-30
Abstract: The filter has a two position switch at its input and output so that it can be looped back on to itself with an amplifier to form an oscillator in which the filter is the resonant element. The centre frequency of the filter is determined by a control voltage which is applied to voltage controlled inductors. The control voltage is determined by a servomechanism which locks the oscillator to a reference. It consists of a programmable divider in the oscillator output, a reference oscillator and a frequency comparator. The comparator output is a logic signal which drives the up down command input of a counter which is clocked slowly when the control voltage is not being held. The same clock also drives a second counter of the same capacity at a higher rate and the two counter outputs are compared. The comparator output drives an integrator which provides the filter control voltage. An increase in polarisation current in the inductors reduces the inductance.

Patent FR-2503008-A1 (FR)
Inventor: MANOGG HORST
IPC: B23Q16/00
Filed: 1982-04-01
Abstract: The invention relates to a stop system, especially for handling devices, which consists essentially of a slide moved, on the one hand, parallel to a positioning spindle equipped with stops and, on the other hand, parallel to an operating-cam strip, to which slide is assigned a control device which cooperates with the drive for directing to intermediate positions. As a result of the invention, any desired intermediate positions situated between end positions can be approached softly from both sides without using a damping device. According to the invention, this is achieved in that firstly a coarse positioning and thereafter a fine positioning is carried out. For the coarse positioning, there is provided on the slide a switch which cooperates with cams, having substantially the position of index nuts, of the operating-cam strip. For the fine positioning, there is provided on the slide an indexing unit which can be approached from both directions and whose indexing bolt engages in the indexing nut which can pass through the indexing unit. According to a particular exemplary embodiment, the positioning spindle is part of a guide unit which consists of two mutually parallel end plates, between which are fastened, in turn, two guide bars parallel to the positioning spindle. The slide is arranged displaceably on these guide bars via a cylinder fixed on it and articulated by its piston rod on one end plate. In this case, the control device consists of switches fixed to the slide and cooperating with actuators provided on the indexing bolt.
Patent FR-2504807-A1 (FR)
Inventor: HEPP DENNIS G
IPC: A61N1/08
Filed: 1982-04-30
Abstract: The keyboard-controlled tissue stimulator based on a microprocessor has pulse output circuits which emit output pulses at times and with amplitudes pre-determined by a microprocessor control arrangement. A microprocessor operates on the basis of user commands input via keys. The commands comprise a stop order which not only terminates the output pulses but also resets the amplitudes to a safe value, so that generation of unpleasantly high output signal levels is avoided on subsequent renewed starting. The OUT key producing the stop order is sited at a conspicuous point on the tissue stimulator housing, so that the user can stop operation very quickly in an emergency. Furthermore, keys for increasing and reducing the output amplitude are provided, and the microprocessor control arrangement responds to these commands in such a way that it changes the output amplitude continuously by pre-determined small increments for as long as the key is pressed. This permits the user to make gentle and accurate adjustments for optimum results. Another key orders the microprocessor control arrangement to switch over to another operation mode, for example pulse surge mode at a low rate.

Title: Power regulator giving continuous control of resistance heater - uses power field effect transistors in series with load to control AC power flow resistance element
Inventor: CARTER BRIAN
IPC: G05D23/24
Filed: 1982-06-09
Abstract: The regulator power circuit comprises a fixed value resistor (Rc) connected in series with a control element having variable resistance (T1, T2). A controller (P, CTN) regulated the value of this variable resistance so as to obtain the required ambient temperature. The variable resistors (T1, T2) are realised from power field effect transistors (FET) mounted in series opposition. The integral drain-source diode provides a current path when the FET is reverse biased. The gates of the FETs are driven from a potential divider comprising a potentiometer (P) used to set the desired temperature and two thermistors, one with a positive temperature coefficient (CTP) and the other with a negative temperature coefficient (CTN).
