Title: Data Transmission Systems
IPC: H04B1/66
Filed: 1979-06-13
Abstract: The exchange of data between a central station and peripheral stations is such that the sharing of time in a multiplex channel is effected by transmitting address signals consisting, for each peripheral station, of only one or several binary signals whose sequence meets a predetermined recurrence relation. Address signals and data signals are transmitted successively; the time intervals between address signals for successive peripheral stations are set according to the availability of data for transmission. The central station incorporates a recurrence sequence generator (1), a code addressing unit (3), and a generator (22) of an irregular sequence of synchronizing pulses, these units being interconnected to produce the required operating procedure. Each of the peripheral stations of the system incorporates circuitry complementary to that of the central station, including a recurrence sequence filter, an address selector, a synchronizing address pulse discriminator, and a controlled generator (51) of an irregular sequence of synchronizing pulses. <IMAGE>

Title: Signal converting unit intended to be incorporated in a pneumatic control system
IPC: G05D16/20
Filed: 1980-02-29
Abstract: The unit serves to convert an electrical control signal (I) received at the input of the unit into a pneumatic signal (P). This is emitted at the output of the unit and its value should be proportional to the value of the control signal (I). The unit comprises a tongue-shaped piezoelectric element (6) which is loaded with a voltage dependent on the control signal, so that the element (6) carries out a lateral bending movement which varies with the voltage. The unit also comprises a pneumatic line (1) with a chamber (1a) which is supplied with compressed air via a throttle (4) and from which the compressed air is conducted through a nozzle (3) located near to one side of the piezoelectric element (6) so that the air pressure in the chamber is regulated by the piezoelectric element (6) as a function of the said voltage; and an outlet line (5) leading from the chamber for transmitting the regulated air pressure to the control system as the said pneumatic signal (P). To make the pneumatic signal (P) to the control system accurately follow the electrical control signal (1), a pressure transducer (7) is connected to the outlet line (5), being designed to produce an electrical signal (T) which corresponds to the regulated air pressure, and which is fed back via a feed-back circuit to the input of the unit. Furthermore, the input has a circuit (9, 11) which receives both the electrical control signal (1) and the fed-back electrical signal (T). The circuit has a device (9) for forming a difference signal by comparing the two signals (I, T) and a device (11) for integrating the difference signal and thereafter producing from the integrated difference signal the voltage with which the piezoelectric element (6) is loaded.

Title: Electronic slave flash delay device
Inventor: ORBAN JOHN MARCEL
IPC: G03B15/05
Filed: 1981-07-30
Abstract: A device for activating an electronic slave flash unit for photographic use includes a circuit wherein there is a delay circuit (33a) responsive to a light sensing signal from sensor 25 after a predetermined time delay to activate a flash unit connected at 55. The time delay of the delay circuit is adjustable as required, and the delayed operation of the flash of the slave flash unit eliminates incorrect impulse signals being transmitted to light sensors of other slave flash units which would otherwise prematurely extinguish their flash and give a resultant incorrect lighting effect. The power for the circuit is obtained from a capacitor (33) which is energized by the flash unit. The energy in the capacitor is used to power the delay circuit, and a Zener diode (36), a unijunction transistor (37), variable resistances (45-49) and a capacitor 43 permit accurate variable time delays. <IMAGE>

Title: Filter connector
IPC: H01R13/719
Filed: 1981-09-15
Abstract: A filter connector comprises a front insulator (14) shaped to house a monolithic capacitor (18) within a slot bordered by rows of contact cavities (26). A thin metallic plate, or spring array (20), is aligned with the front insulator so that a plurality of spring tabs on the spring array project inwardly into the insulator slot and each of a plurality of spring tines on the spring array project inwardly into a correspondingly-aligned contact cavity. The capacitor (18) is then inserted into the slot so that external electrodes thereon contact a spring tab aligned therewith. A contact pin (34) is then inserted into a contact cavity, causing the spring tine to deflect and make contact. A rear insulator (22) is then aligned with the spring array to sandwich the spring array between the front and rear insulators. The rear insulator breaks portions of the spring array and thereby isolates each spring of the array. In an alternative version, the slot for the capacitor intersects each contact cavity, and each contact has an integral outwardly-extending spring finger which when the contact is in the cavity ends into the slot to engage one of the capacitors live electrodes. The two insulators, when fitted together, retain the contacts and the capacitor in the cavities and the slots respectively. <IMAGE>

Title: Method and apparatus for overhead signalling
IPC: H04J3/06
Filed: 1982-01-12
Abstract: A bit-interleaved synchronization technique is described in which the signals used to maintain synchronization are distributed throughout the frame. Advantageously, this technique is used in a system in which the frame is generated automatically from a knowledge of the individual data channel and aggregate channel transmission rates. In the course of generating the frame, frame sync signals are distributed throughout the frame so that no two signals are contiguous. In accordance with the invention, the same distribution technique can be used with other types of overhead signals as well.
