Said diesel fuel shut-off lever (7) is kinematically connected with an electromechanical actuator (9) which is kinematically connected with a feedback transducer (10) of the electromechanical actuator position. Moreover, said control lever (8) of said all-range mechanical regulator (4) is kinematically connected with a pedal (11) for controlling the speed of the engine (1), said pedal (11) in turn being kinematically connected with its position-sensitive transducer (12). A gas mainline (13) is connected, on its one side, through a valve block (14) provided with a built-in electromagnetic valve (15), to a gas cylinder (16) containing a liquefied gas fuel, and, on its other side, through a shut-off filtering valve (17), an evaporating gas-pressure reducer (18) and a gas filter (19), to a control rod (20) provided with gas injectors (21).

Abstract: PCT No. PCT/DE90/00491 Sec. 371 Date Mar. 4, 1991 Sec. 102(e) Date Mar. 4, 1991 PCT Filed Jul. 1, 1990 PCT Pub. No. WO91/00196 PCT Pub. Date Jan. 10, 1991.Electromotor driven tensioning and winding device for lashing straps (7) in integral construction, preferably including a tactile three-point measurement sensor (2) in direct contact with a flat side (40) of the lashing strap (7). For this purpose, the measurement sensor (2) includes a sensor bar (30) which is mounted against a compression spring element (31) and has a contact pin (34) which is movable together with the sensor bar (30) and can be pressed against a contact plate (37) fastened to the rear wall (32) of the measurement sensor housing (27). If the desired tension of the lashing strap is reached, the contact pin (34) lies against the contact plate (37). If the contact between the contact plate (37) and the contact pin (34) is interrupted, the drive motor (3) receives a signal to tighten the lashing strap (7) by further winding it onto the wind-up spindle (6). The desired lashing tension of the lashing strap (7) is thus regulated continuously.

Abstract: 1,011,399. Data transmission; transistor pulse shaping circuits. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. May 6, 1963 [May 7, 1962], No. 17820/63. Headings H3T and H4P. In a telegraph system in which there is a large information content in a given bandwidth, binary input pulses to the transmitter are converted to a data pulse train to be transmitted, in which successive transmitted pulses have the same value if the corresponding input 1 bits are adjacent, and have the opposite value if the corresponding pulses are separated by one or more 0 bits. The 0 bits are transmitted as a like number of pulses of intermediate value. In a first embodiment, the transmitter, Fig. 1A, has an input E, Fig. 1B, at 6000 Bd. which is to be transmitted over a low-pass channel having a bandwidth of 3000 Bd. Odd and even pulse are separated, spI, spP, and stretched, elI, elP. An oscillator Os provides a sinusoidal signal OS at a frequency of one half the data bit rate and which is phase-shifted by + 45 degrees and - 45 degrees, d +, d- , raised in D.C. level, eaI, eaP, and gated with elI, elP in coincidence gates PI, PP. The resultant waveforms pI, PP are added to give adI which is fed to coincidence gates P<SP>1</SP>, P<SP>11</SP>. These gates are alternately open, under control of baI, baO from bi-stable circuit Ba which is fed by the original data E after being stretched, el, and differentiated, gI. The output of gate P<SP>11</SP>, p<SP>11</SP>, and the inverted output, ir, of gate, P<SP>1</SP>, are added to give ad2, this waveform being smoothed in Cr so that the resultant waveform cr can be transmitted over a 3000 Bd. channel. Circuit Cr is shown in Fig. 1C and comprises diodes Rd1, Rd2 working on the parabolic part of their range. At the receiver, Fig. 3 (not shown), the input signals are frequency doubled to provide a signal which is gated with clock pulses at bit frequency derived from the doubled signal. The output of the gate is at 6000 Bd. and is identical to the original data E. An arrangement for transmitting in a bandpass channel is described with reference to Fig. 2 (not shown) and the receiver with reference to Fig. 4 (not shown). The data signals are divided between odd and even channels as before and each channel includes means for deriving a quarter bit-rate signal which passes to a modulator, the modulators being fed with carriers phase displaced by 90 degrees. The modulated signals are added and transmitted. At the receiver the signals are separated to odd and even channels, frequency doubled, gated, and summed to reproduce the original data. Fig. 5A (not shown) illustrates a variation of the arrangement described above with reference to Figs. 1A, 1B.

Title: Engine retarding system
Inventor: CAVANGH MARK STEVEN
IPC: F02D13/04
Filed: 1982-12-23
Abstract: A hydraulic reset mechanism is provided for an engine retarder of the compression relief type. The mechanism includes a pin valve and senses the force required to hold open an exhaust valve. When this force has decreased substantially from the force required to open the exhaust valve initially, the pin valve is opened in the hydraulic system to release the hydraulic pressure and permit the exhaust valve to close. The mechanism thereby assures that the engine exhaust valves are closed, or substantially closed, prior to the normal opening of the exhaust valves at the end of the power stroke of the engine without affecting the retarding horsepower produced by the engine brake.
