Title: Improvements in or relating to echo sounding apparatus
Inventor: RICHTER FRIEDRICH
IPC: G01S7/60
Filed: 1958-11-05
Abstract: 867,768. Echo-sounding. ELECTROACUSTIC G.m.b.H. Nov. 5, 1958, No. 35555/58. Class 40(7) [Also in Group XIX] In echo-sounding apparatus having a release device for the periodic emission of sound pulses continuously adjustable relative to a recording member, the adjustment is effected by displacement of a gear part. In the apparatus described echo indication is given on a recorder and a cathode-ray oscilloscope (C.R.O.) both of which are adjustable relative to the instant of sound emission such that the partial zones over which they indicate are at the same or different positions of the total sounding zone. Graticule 3 over recording surface 1 is displaced vertically to follow the adjustment of the recorder partial zone identified by marks 4 and C.R. tube 2 shows the instantaneous recording to a larger scale. Recording member 41 rotates at constant speed and shaft 11, connected to the former's drive unit through gearing 9, 10, causes cam 5 to rotate at half member 41 speed thus affording one sound pulse emission per member 41 revolution via contacts 6 or 7. Lateral displacement of member 10 causes member 9 to rotate proportionally and the timing of the pulse emission relative to the entry of the recording member into its recording path is thus altered. Similarly the timing relative to pulse emission of the triggering of the C.R.O. time base, via contacts 18, 19, is adjustable by lateral displacement of gear part 15. Shaft 8 also carries a contact drum 21 on which are arranged five groups of metal ridges 22 for bridging contacts 23, 25. The springs of the contacts are displaceable relative to one another for adjustment of recording trace width and the whole contact assembly is displaceable in steps by a controlling groove on drum 27 for use when the echo trace moves off the recording surface. The zone-defining trace lines 4 are interrupted by gear 28, cam 30 and contacts 29 to reduce obscuration of recorded echoes. Correlation between graticule 3 and the recording is effected by wheel 40 mounted on a shaft carrying a rack to adjust member 10, Fig. 4 (not shown). In another embodiment a planetary gear system is used, Figs. 6 and 7 (not shown).

Title: Asynchronous digital multiplexer
IPC: H04J3/07
Filed: 1973-07-26
Abstract: 1427084 Multiplex pulse code signalling STANDARD TELEPHONES & CABLES Ltd 26 July 1973 35606/73 Heading H4L In a multiplex digital data transmission system, incoming data received at interface 2 is written into an 8-bit store 3 under the control of clock pulses W derived from the data stream and is read out at a higher rate under the control of basic clock signals R modified for stuffing purposes by an inhibit gate 4 to provide read out pulses SR. Pulses SR and W are compared in phase at 5 and when they tend to coincide a trigger pulse is generated and supplied to a stuff store 6 which holes an instruction to stuff until it is enabled by a pulse SS, whereby the gate 4 is caused to block one pulse R. By this means the read out is delayed by one bit period and the duration of the previous bit is extended to cover two successive bit periods, a signal at 7 indicating that stuffing has taken place. Each frame is divided into four subframes, Fig. 2 (not shown) and certain time slots in subframes 2, 3 and 4 are used to transmit stuffing information and others in subframe are used for frame synchronization.

In a jet propelled aircraft, take-off and landing is facilitated by arranging laterally disposed jetpropulsion units 7, 7a for pivotal movement about transverse axes and by the provision of adjustable deflectors 48, 48a, 49, 49a in the jet nozzle of an engine (not shown) mounted in the fuselage. A pilot-controlled lever 26 controls through a circuit 27 an electromagnetic valve 28 connected to a hydraulic valve 29 controlling through pipes 30, 30a jacks 18, 18a which rotate the engines 7, 7a respectively. A branch circuit 31 from circuit 27 controls a device (not shown) for operating the deflectors 48-49a. The power output of engines 7 and 7a may be controlled by levers 32, 32a connected through control lines 33, 33a to throttle valves (not shown). The elevator, aileron and rudder controls are conventionally operated from the control column 40 and rudder pedals 37 and servo-control mechanisms such as electrically operated jacks 45, 46 and 47 are inserted in the control rods 38, 41, 43 and 43a respectively. The deflectors 48, 48a are controlled by an electrically operated jack 51 connected to the rudder control rod 38. Similarly, deflectors 49, 49a are controlled by a jack 55 connected to the elevator control rod 41. For the purpose of automatic stabilization the jacks 51 and 55 are further controlled respectively by ampliers 50 and 56 which receive signals from gyro references 52, 57 and devices 53, 58 responsive to aircraft speed. Lateral stabilization is obtained by connecting the aileron control rods 43, 43a and the throttle valves for engines 7 and 7a to jacks 63, 63a energized from amplifiers 64, 64a supplied with signals from a gyro reference 65 and an aircraft-speed responsive device 66. A take-off platform, Fig. 10 (not shown) is described consisting of a fixed base member and an inclinable platform, operated by a cable winch from a horizontal position in which the aircraft is run on to the platform to an inclined position appropriate for take-off. Ducts are provided in alignment with engines 7 and 7a when in their vertical positions so that exhaust gases may be re-directed on to the undersurfaces of the aircraft wings. A warning lamp placed on the ground in view of the pilot is switched off by a cable connected to the aircraft to give the pilot an indication of height in order that he may rotate with safety, the engines 7 and 7a into their forward-propulsion positions.

Abstract: 840,806. Typewriters; number-printing apparatus. INTERNATIONAL BUSINESS MACHINES CORPORATION. Nov. 22, 1956 [Nov. 25, 1955], No. 35804/56. Classes 100(2) and 100(4). In a power driven type-lever machine in which individual type-actions are triggered by electrical solenoids 14, a device for selectively energizing the solenoids is included which comprises a plurality of multi-contact distributing switches 38-1 to 38-100T connected to the solenoids and a plural contact emitter 32 for sending a pulse through each order of the distributing switches seriation to the solenoids 14. The device is used to print accurately a six figure serial number by the single action of a switch 50. Upon the next operation of the switch 50 the next succeeding number is printed automatically digit-by-digit. Operation of the switch 50 operates a relay 52 and a hold relay 54, and a magnet 34 is energized to step the emitter 32 to the first contact which is wired to the hundred thousands digit of the distributer switch 38. Now when the switch 50 is released a pulse from line 44 passes along line 49, through ribbon actuator contacts 28 to the emitter 32, and according to the position of a rotary arm 42, the corresponding digit solenoid 14 is operated to trigger its type lever. Contacts 28 are opened during movement of all type-levers and during return movement contacts 30 are closed to effect re-operation of magnet 34 which advances the emitter to contact 2 so that the pulse is routed to the tenthousands distributer switch 38. This operation is repeated until all digits have been printed and emitter switches to contacts 7 and 8 when an unlatching magnet 56 disconnects the hold magnet 54 so that the device stops until the switch 50 is again operated. The switch 38 is advanced by individual advance magnets 60, operated by the switch 50 and subsequently by the pulse. A nines-carry switch, mechanically coupled to the switch 38, is provided to advance the preceding digit switch when the succeeding switch reaches the digit nine. Specification 749,565 is referred to.
