Title: Semi-trailer supporting jack - has rubber cushion at base allowing tilting movement of support plate
Inventor: DALTON THOMAS
IPC: B66C23/78
Filed: 1975-01-11
Abstract: The jack is particularly of the twin-type, being designed to support the semi-trailer without overloading individual jacks after the tractor unit has driven clear even on an uneven surface. Between the support plate (3) at the foot and the end plate of the jack proper (1) is a rubber cushion (2) with a central cylindrical recess (6), and an further recess (7) concentric to it. A collar (8) on the support plate encloses this cushion and the jack end plate (5), which protrudes beyond the sides of the jack, being so shaped as to allow a certain amount of movement of the support plate in relation to the jack in all directions, while preventing the plate falling off.

Title: Switchgear cabinet with metal casing around busbar ends - to provide burn-out regions for arc travelling through compartments
Inventor: HAGEN DIETRICH
IPC: H02B1/21
Filed: 1975-02-20
Abstract: The switchgear cabinet has several adjacent areas separated by partitions. Polyphase busbars pass through openings in these enclosed partitions. Instead of inter partition closure to limit arc travel, metal cases (5) are located at both end areas at the height of the bushbars (4). These cases enclose the ends of the buses and have pressure release valves (7) in case of short circuiting. These valves may be simple hinged flaps in the tops of the cases. Any arc generated between the busbars travels along through all the cells (without damaging any of them) and into one of the end cases, where it burns until quenched.

Title: Transformerless isolation circuit for separating load from supply - uses rectification, frequency conversion and reactance coupling for transmission
IPC: H02M7/48
Filed: 1975-02-24
Abstract: An alternating waveform at the input terminals of the isolation device is first rectified in a full-wave bridge and connected to a chopper circuit. The chopper circuit operates at a much higher frequency than the original, and its output is connected across a four capacitor network with an earthed centre-tap. The signal from this circuit of the rectified in a full-wave bridge, and the DC output of the rectifier bridge is polarity corrected and passed to a low-pass filter. The output signal has a frequency identical to that of the input and is completely isolated from it. One leg of the output circuit may be earthed if required.

Title: Sewage surface aeration impeller - mounted under conical cowl with air inlets and contacting fluid surface at safe distance
Inventor: STEUER JOERG DIPL ING
IPC: C02F3/16
Filed: 1975-09-03
Abstract: Sewage and other effluents are aerated by aerating impellers near the surface. A cowl which is fixed to the bridge carrying the drive mechanism has air inlet openings near the centre. The outer edge of the conical cowl contacts the water surface about 0.5m away from the point of impact of the water fountain produced by the impeller. This prevents pollution of the working area of the personnel by sprays of activated sludge. The bridge and surroundings remain clean and the amount of cleaning necessary is greatly reduced. The impellers do not freeze up in winter and the chilling of the sewage is reduced.

Title: Effervescent anhydrous sodium citrate and citric acid granulate - prepd. with water in fluidised bed granulator
Inventor: KRAMER HELMUT DR
IPC: A61K9/46
Filed: 1975-11-28
Abstract: Mixing ratio Na citrate: citric acid is 3:1 to 30:1 (esp. 5:1 to 17.5:1). Ratio water to mixt. is 1:1 to 4:1 (1:2). Air supplied to granulator is heated at 80-140 (120) degrees C.

Title: Noise suppressor for voice plus data communications - uses noise detector and suitable delay circuit to open series switch
Inventor: FRENZKE UWE DIPL ING
IPC: H03G3/34
Filed: 1976-08-24
Abstract: The noise suppressor, for communications equipment (esp. voice links with intersticed data blocks) has the received LF signal passing one way over a noise detector (2) to a delay line (3) and the other way over a second delay line (4) to a switch (5). The switch is controlled by the output of the first delay line and switches the output of the second delay line through to the amplifier (6) driving the loudspeaker (7). The delay times are chosen so that the noise detected in the LF signal can be blocked by opening the switch, ie. by the time the noisy signal reches the switch the latter is open.
Patent DE-2644733-A1 (DE)
Inventor: VEEN WOUTER MARTINUS DIRK VAN
IPC: G11C29/14
Filed: 1976-10-04
Abstract: A read/write memory of n stages, periodically addressed in a recurrent scanning cycle of n time slots in which binary words are written in and read out from respective stages, is connected to a data-handling network by way of a writing multiple and a reading multiple each traversing a respective selective inverter, i.e., an upstream inverter in the writing multiple and a downstream inverter in the reading multiple. The two inverters are controlled by a generator of pseudo-random binary signals, unrelated to those processed in the data-handling network, having an operating cycle coextensive with a scanning cycle. Depending on the character of the control signals issuing from this pseudo-random generator during each cycle, the two selective inverters pass the bits of their incoming words either in their original or in a complemented form; with words written in a memory stage in one cycle read out in the immediately following cycle, the control signals delivered to the two inverters are identical but staggered by one cycle so that the words appearing in the output of the downstream inverter match those fed into the upstream inverter in the preceding cycle when the memory operates properly. Under certain circumstances, when a memory stage is addressed out of turn so that loading and reading of its contents occur successively in the same cycle, the staggering of the two control signals is canceled. Malfunctions of the memory are detected by parity checks carried out on the words traveling along the reading multiple to the downstream inverter; an alarm signal is emitted upon the occurrence of an error in the same bit position in two consecutive cycles.
Patent DE-2652772-A1 (DE)
Inventor: SCHLEICHER HELMUT DR
IPC: G04F3/06
Filed: 1976-11-18
Abstract: In this electronic multi-range time-delay relay, the setting member, e.g. potentiometer, which serves to set the time in a stepless fashion is operated by means of a transparent rotary knob (1) which overlaps the major part of the relay front panel (4). The time scale (12), which preferably occupies the edge region of the rotary knob (1), can be provided on the rotary knob or on the front panel. A correspondingly smaller changeover knob (2) is present on the rotary knob (1) for the purpose of preselecting the timing ranges. The changeover knob (2) is mounted on a spindle which is guided through the rotary knob (1) and the setting member for setting the time in a stepless fashion. The spindle is part of a changeover switch by means of which different resistors, for example, for the individual timing ranges are switched into the circuit. By comparison with the conventional juxtaposition of stepless and range time setting, this superimposed arrangement of knobs and setting means facilitates optimum use of space for miniaturisation in conjunction with a simultaneously guaranteed accuracy of setting. <IMAGE>
