Title: Improvements in telephone substation circuits
IPC: H04B3/20
Filed: 1944-03-15
Abstract: 582,801. Substation equipment. AUTOMATIC TELEPHONE & ELECTRIC CO., Ltd. March 15, 1944, No. 4793. Convention date, May 10, 1943. [Class 40 (iv)] In a two-way automatic substation amplifier, having a balancing network such as a hybrid coil, one of the amplifiers is disabled to prevent acoustic reaction, during the period of unbalance, due to the line being open-circuited while the call is being set up. In the circuit shown in Fig. 2, incoming dial tone passes from the receive amplifier 32 via the low-pass filter 41 to the anode-band rectifier 45 whose anode current operates relay 110 through coil 111, to short-circuit the microphone 35. On dialling, relay 110 is kept operated by the off-normal contact 51 over coil 112, and subsequently by the ring-back tone over the same path as for the dial tone. High-frequency currents from the answering subscriber's voice, pass via the high-pass filter 42 to the rectifier 58 whose anode current operates relay 120, which releases the disabling relay 110 at contact 123. Contact 122 disconnects the high-pass and lowpass filters and 121 locks relay 120 until the amplifier is switched off at the end of the conversation. Delay network 53, 54, 55 is provided to hold relay 110 operated during the interval between completion of dialling and ring-back tone. Relay 110 may be arranged instead to short-circuit the loud-speaker or to put a heavy negative bias on a valve of either of the transmit or receive amplifier. In a modification, Fig. 3 (not shown), release of the relay 110 on operation of relay 120 is hastened by a reverse current caused by the discharge of a condenser. In another modification Fig. 1 (not shown), disablement of the amplifier is caused by a relay, operated by the dial off-normal contacts and locked until released by rectified high-frequency voice currents from the answering subscriber. Specification 581,380 is referred to.

Title: Improvements in or relating to directional aerial arrangements
IPC: H01Q5/00
Filed: 1966-02-04
Abstract: 1,136,643. Aerials; radio guidance and radar. TELEFUNKEN PATENTVERWERTUNGS G.m.b.H. 4 Feb., 1966 [19 March, 1965], No. 5018/66. Headings H4A and H4D. [Also in Division G2] In an aerial arrangement of the Cassegrain type, radiation from a radiator 4 impinging on the front face of an auxiliary reflector 3 is directed to the face of a main reflector 1 and is beamed along an axis 2. The back surface of the said auxiliary reflector 3 is arranged to constitute the main reflector for a second aerial system comprising also a radiating horn 7 (or another Cassegrain type feed) so that a second beam, which may be further concentrated by a lens 8, is projected along the axis 2. A dielectric lens 9, similar to a Schmidt optical system, may be provided to compensate the first system for the effect of the second system, and the two beams may be cross-polarized. In an application to radar, a transmitter 5 and a receiver 6 are both coupled to the radiator 4 through a duplexer. Alternatively, one aerial system may be used for transmission and the other for reception, and a monopulse system may be used. The frequencies of the two aerial systems may differ, and at least one may be operated at an optical frequency, for example, one operating in the infra-red range could substitute for the other operating at a normal radar frequency if the latter were jammed. One of the systems could be used for long-range pick-up of a target and the other, operating at a higher frequency, for tracking the target. If one system is adapted for monopulse operation and has a stack of four primary radiators which are used simultaneously during transmission, symmetrical feeding of the said radiators is facilitated by providing a suitable lens arrangement. Among other applications of the invention are stated to be, three-dimensional radar using V-beams, secondary radar, and remote control of bodies by guiding rays as described in Specification 845,633.

Abstract: 1,245,041. Seismic exploration. CHEVRON RESEARCH CO. 29 Jan., 1969 [29 Jan., 1968], No. 5049/69. Heading H4D. Relates to obtaining and processing seismic records so that both the " in-line dip" and " cross-dip " (relative to a survey line) of subsurface strata can be determined. In the simplified example illustrated in Fig. 1, sources are energized in turn at shot points S1 to S6 and for each shot the outputs of detectors G1 to G6 on the survey line 23 are recorded individually at 25 to give a multi-trace record for each shot. Static and dynamic corrections are applied to the traces so that each corrected trace is effectively the trace which would have been recorded if both shot and detector were at the respective associated centre-point C1 C2, C3 &c. The corrected traces are then re-grouped and recorded as multi-trace sets, where the traces of a particular set are those associated with centrepoints lying on a line perpendicular to the survey line and intersecting it at a respective in-line point X1, X2 &c. (e.g. one set will comprise the traces recorded with detector G1 and shots S1 to S6, associated with centrepoints C1, C7, C13, C19, C25, C31 and in-line point XI). By relatively time-shifting and compositing the traces within a set (referred to as " beam-steering," a " directional trace " representing energy incident from a particular narrow angular sector, Fig. 3, is obtained. This beam-steering is repeated with different time-shifts to derive from that set a group of directional traces each with a dffierent steering angle 31a, 31b &c. Similar groups of directional traces are derived for the other sets. Visual records and seismic sections may be prepared from the directional traces (details given). To determine the cross-dip of a stratum, the visual records are examined to find which directional trace group shows the corresponding event most prominently. The cross-dip is then equal to the steering angle of that group (if the seismic wave is not rofracted, i.e. if the wave velocity is constant with depth) or can be calculated from it (if a velocity/depth profile is known or assumed). The in-line dip is then found by comparing directional traces having that steering angle but associated with different in-line point X. Details are given of a moving-head magnetic recording/playback system for the trace re-grouping and beam-steering processing. The use of larger and alternative sourcedetector arrays are discussed.

Abstract: 124,202. British Westinghouse Electric & Manufacturing Co., (Assignees of Hodgkinson, F.). July 10, 1917, [Convention date]. Motor power plant; regulating. -Relates to governing means for compound engines or turbines, and comprises means responsive to variations in the speed of the high-pressure section for controlling the operation of the lowpressure section and means responsive to variations in the speed of the low - pressure section for shifting the function of governing the low-pressure section from the first to the second of said means. For example, in a turbo-generator installation, Fig. 1, comprising a high-pressure turbine section 10 and two low-pressure turbine sections 11, 11<1> connected in parallel, in the event of an accident unloading say the section 11', the sections 10, 11 continue in operation under load under the control of the governor 15 of the high-pressure section, while the section 11<1> is automatically isolated by a governor 22, which is adapted first to cut off the fluid supply coming from the section 10 by closing a gate valve 20 when the speed of the section 11<1> becomes excessive, and then to admit sufficient live steam through a valve 23 to keep the section 11<1> running at. normal speed. Excess fluid from the section escapes through a relief valve 28<a>. A modification is described wherein a high-pressure turbine is connected in series with a duplex low-pressure turbine by a conduit having a gate valve such as 20. An application of the invention to the turbine described in Specification 17643/14 is described, and in this modification, the gate valve may be closed by the governor of the initial section. The control of the gate valve may be effected by a governor 37a, Fig. 4, controlling a pressure-actuated device 39, Fig. 6, and a trip mechanism 43, Figs. 4 and 5. Mounted on the governor lever 37<b> is a finger 47 adapted to release from a latch 46 a trip lever 45 and so allow a valve 44 to open and permit the space below a differential piston 60 to be exhausted. The piston 60 thereupon shifts a valve 52, admitting pressure fluid below a piston 49 which thereupon shuts the gate valve mounted on its rod 50. For subsequently opening the valve admitting highpressure steam to the low-pressure section, the governor 37a is connected thereto through a relay.
