Title: Interfaces for data transmission systems
IPC: G06F13/42
Filed: 1974-05-02
Abstract: 1467726 Data transmission SOLARTRON ELECTRONIC GROUP Ltd 30 April 1975 [2 May 1974] 19366/74 Heading H4P A data transmission system includes an interface which can be connected between two highways as well as between a highway and a device such as a data source or a data acceptor, whereby a controller, e.g. a computer, on one highway is able to exercise control over the other highway. As shown, an interface comprises two ports 1, 2 each including data terminals 10 and control terminals 11, 12. A special command signal on terminal 11 determines whether a data byte received at terminal 10 is information or a command, and status circuits 16, 16a responsive to command bytes accompanied by the special command signal received at either port establish different statuses of the interface, including statuses in which the data terminals 10 of the ports are placed in communication for the flow of data in either selected one of the two directions between the ports, the status circuits responding to a predetermined signal associated with a command byte which addresses the interface whereby the interface enters a status in which a byte received at the addressed port is modified and sent as a command byte from the other port. The predetermined signal may be a predetermined value of one bit of a data byte which addresses the interface, or a predetermined byte following on the command byte which addressed the interface. Thus the arrangement is such that a command byte can be transmitted through an interface, which can therefore be used to interconnect two highways, and examples of such interconnected systems are described with reference to Figs. 2 to 7 (not shown).

Title: Remote control receiver for central remote control installations utilising audio-frequency signals superimposed on the mains network
IPC: H02J13/00
Filed: 1957-06-21
Abstract: 829,230. Electric selective signalling systems. LANDIS & GYR A.G. June 21, 1957 [June 23, 1956], No. 19653/57. Class 40 (1). In a receiver for a selective signalling system operating on the synchronous selector principle and using audio-frequency pulses superimposed on the mains, a mechanism is provided whereby the receiver only makes a complete revolution upon the receipt of a start pulse of a certain minimum duration, the mechanism automatically resetting the receiver after start pulses (or spurious pulses) of a lesser duration than the said minimum duration. The receiver comprises a main shaft W, Fig. 1, which drives the distributer, and an auxiliary shaft HW which drives the said mechanism, both shafts being driven in the directions indicated by a synchronous motor M. Fixed to the auxiliary shaft HW is a disc R and freely pivoted on it is a resetting lever RH, which, in its rest position, is held against a fixed abutment P by a spring RF. Pivoted to the resetting lever RH is a lever K having a finger S which normally engages a recess on the periphery of the disc R, and a pin B which in its normal position holds a spring-loaded contact K2 away from a contact K1 and in contact with a contact K3. A further lever AH mounted on a fixed pivot T and loaded by a spring AF is also provided. In operation a start pulse closes a contact r to energize the synchronous motor M. The disc R rotates, in the direction indicated, causing the resetting lever RH to rotate about the shaft HW carrying the lever K slides against an end H of the lever AH without moving it. If the start pulse is not of the required minimum duration when it ends the mechanism will be returned to its reset position by the spring RF. If the start pulse is sufficiently long the resetting lever RH, carrying the lever K with it, will continue to rotate until an end F of the lever K can pass beneath the end H of the lever AH, as shown in Fig. 2, under the pressure of the contact K2 on the pin B to thereby connect the synchronous motor M direct to the mains U. A complete rotation of the shaft W then follows and the mechanism is reset by the action of a cam A fixed to the shaft W.

Title: Improvements in or relating to craft guidance apparatus
IPC: G05D1/06
Filed: 1946-07-01
Abstract: 646,702. Radio-navigation. STEVENS, A. H. (Sperry Gyroscope Co., Inc.). July 1, 1946, No. 19655. [A Specification was laid open to inspection under Sect. 91 of the Acts, Jan. 3, 1947.] [Class 40 (vii)] Radio - navigating apparatus mounted upon a craft comprises an indicator having a movable pointer which is controlled by the sum of signals measuring respectively the displacement of the craft from a predetermined course line and the heading of the craft with respect to a predetermined heading, so that, when the pointer is maintained in alignment with a reference index, the craft approaches the course-line asymptotically. The Figure illustrates apparatus for use in an aircraft in conjunction with overlapping-beam localizer and glide-path radio beacons. The indicator 10 comprises, in addition to the pointers 12 and 14 which are each controlled by signals derived from both a respective radio beacon and respective gyroscopic apparatus, pointers 11 and 13 which are responsive to beacon signals only and indicate the deviation of the craft from a predetermined landing-path in azimuth and elevation respectively. The output from the localizer receiver 20 actuates the galvanometer 17 which is coupled through gearing to the pointer 11 to deflect it in accordance with the output from the receiver. Pointer 12 is deflected by means of galvanometer 18 which is actuated by the sum of signals derived from receiver 20 and a phase-sensitive detector 44, the output of which is controlled by gyro-compass 22. The compass 22 controls the position of a winding 47 energized from a source 46 relative to a winding 48. The signal induced in winding 48 is applied to winding 49 which induces an alternating voltage in winding 25 having an amplitude and phase dependent upon the compass setting. The winding 49 is initially rotated by the handle 29 to a position dependent upon the direction in which the localizer-beacon course-line extends. The amplitude of the output of winding 25 is thus dependent upon the deviation between the heading of the craft and the direction of the course line, the phase being reversed according as to whether the deviation is in one or the other direction. This output is applied to phasesensitive amplitude detector 44 which consequently delivers a signal of magnitude and sign dependent upon the heading of the craft. A similar system involving glide-path receiver 33 and gyro-horizon 41 is used to control pointers 13 and 14. Drift indication and correction. Drift is indicated by the craft failing to approach the desired course-line asymptotically when the pointer 12 is maintained in its central position, the pointer 11 approaching a constant but not zero position. The drift may be corrected by adjustment of handle 58, which provides a further control upon the relative positions of windings 25 and 49, until both pointers approach zero together. The drift angle may then be read off dial 60.
