Patent GB-796160-A (GB)
Abstract: 796,160. Electric selective signalling systems. SOC. TECHNIQUE POUR L'INDUSTRIE NOUVELLE SOC. ANON. STIN. July 22, 1955 [July 22, 1954; June 29, 1955], No. 21217/55. Class 40 (1). In a remote control system, e.g. for controlling signals and points on railways, of the type in which the operation of a key at the transmitting station initiates a direct current pulse which can have one of two states and is transmitted to the receiver, if the receiving equipment is in order an answering pulse of the same polarity but derived from a different source is sent back to the transmitter and initiates the operation of a fault indicating device at the transmitter and also operates a transmitting switch to terminate the direct current pulse, correct operation of the transmitting switch halting the operation of the fault-indicating device before the latter has had time to become effective. As shown in Fig. 1, a transmitting station S supplies positive or negative pulses via switches X1, X2 or Y1, Y2 to a receiving station E, the polarity of the pulses being controlled through a key P, Fig. 3, and relay X representing " on " or a key Q and relay Y representing " off ". When the polarity of the control pulse is changed, for example the control is from " on " to " off," relay Y is energized via contact Q and locks and through Y1, Y2, energizes pulse relays B and D. Relays A, B, C, D are polarized, or are in series with appropriately soled rectifiers. Relay AB, Fig. 7, at the receiver is energized via contact B2 and EM1 and locks, since the relays EP and EM, Fig. 6, at the receiver, which corrrespond respectively to " on " and " off " and are mechanically interlocked so that they keep the controlled position when deenergized, are in the " on " position as shown. Relay EM is energized via AB4 and B1, to indicate the control " off " and releases EP. Through contacts B3, B4, AB1, EM2, a battery N is placed in series with the battery M, the resulting increased current energizing a relay W at the transmitter and through contacts W1 and W2 relay CD, Fig. 4, and the fault-indicating, slow-acting relay V, Fig. 5, are energized, a relay SM (not shown) at the transmitter, still being in the " on " position (SM1 closed). Since CD acts more quickly than V the circuit of V is broken before its armature has operated, and CD1 opens to de-energize Y and the pulse is terminated. Relays B and D are de-energized and relays AB, and CD, return to normal. Back contacts on relays A or B and C or D advance stepping mechanism in a manner not described, to the next position. If CD fails to operate relay V is operated to give an indication of a fault. If the test current produced by the series connection of batteries M and N fails to arrive W is not operated, CD and V are not energized and the circuit of relay X or Y remains closed so that the control pulse is not terminated. Stepping cannot take place and the fault is indicated by means not shown. In an alternative arrangement, Fig. 2 (not shown), and A.C. test current is used which is coupled to the line and the relay W via a transformer and capacitor and is isolated from the D.C. circuits by chokes.

Patent GB-2109640-A (GB)
Title: Waveguide construction
Inventor: WISBEY PHILIP HENRY
IPC: H01P3/00
Filed: 1981-10-02
Abstract: One method currently being used to construct millimetric waveguides involves the screen printing onto the appropriate surface of a thick film of dielectric in the required pattern. However, certain difficulties have arisen; the special pasty film-forming compositions that have had to be developed to allow guides to be formed by a screen printing process make it almost impossible to form a printed image of the required high resolution and fine detail, primarily because as the screen is removed so the pastiness of the composition causes it to be dragged off the dielectric surface, so destroying the fine detail. The present invention provides an alternative mode of construction of dielectric waveguides, wherein a correspondingly-shaped and dimensioned channel (36) is formed in a substrate (34, 35) which either is or is then rendered conductive, a suitable dielectric paste or frit (37) is placed into the channel so as to fill it, and "fixed" into position, and the "open" surface of the fixed dielectric (37) is then smoothed off, and optionally closed with a conductive cover (38), to form the desired waveguide. <IMAGE>

Title: Fuel injection nozzle
Inventor: MOWBRAY DORIAN FARRER
IPC: F02M61/20
Filed: 1982-06-16
Abstract: A piston member 20 defines a surface against which fuel under pressure in a chamber 21 can act to assist the action of spring 22 in biasing the valve member 14 onto its seat. The fuel under pressure in the chamber 21 is obtained from the nozzle fuel inlet passage 18 and is controlled by a valve element 24 sidable within a bore 23 in the piston member 20. One end of the bore is open to the chamber 21 and the other end to a drain passage 15. The element 24 is biased by a spring 25 towards the one end of the bore 23 so that its position in the bore depends upon the pressure in the chamber. The element 24 and the wall of the bore 23 define a groove 29 and a port 28 which remain in communication to permit fuel flow to the chamber 20 until the pressure therein rises to a predetermined value. This pressure value occurs part way through the engine speed range at full load and determines the maximum nozzle opening pressure. <IMAGE>

Title: A hybrid R.F. frequency-changer
Inventor: MARCO ROBIN JOHN HENRY
IPC: H03D7/06
Filed: 1982-06-29
Abstract: A low operating voltage heptode electronic valve radio frequency changer V1 has a bi-polar transistor local oscillator T1. The advantages of an electronic valve mixer are its inability to be destroyed by ionizing radiation and freedom from spurious mixing that can occur in a semi-conductor device due to electrons passing from the atomic orbit of one semi-conductor atom to its adjacent semi-conductor atom thereby internally generating quantum radiation, can outweigh the need for 12.6 volts at 150mA to power the heater of a commercially available heptode valve. The remainder of the receiver herein uses lead shielded bi-polar transistors and the whole runs off twelve 1.2 volt ni-cad rechargeable cells because the valves' conversion gain is much higher. A resistor is used to drop the 14.8 volt supply to 12.6 volts for the valve's heater. <IMAGE>
