Title: Squeeze drying etc. sugar beet in two stages - with second piston comprising port to connect first and second pressing chambers
Inventor: BAUR ROLF ING GRAD
IPC: B30B9/06
Filed: 1980-09-23
Abstract: Prods. contg. liquids, esp. sliced sugar beet are squeeze-dried in a press comprising two chambers with two separately operating pistons. A first chamber is filled from the feed shaft, the feed shaft is then closed, and the first piston precompresses the material against the rear of the second piston, which at this stage obturates its opening. The second piston, which is of two-part construction, now opens the passage to permit the product to be forced by the continuing movement of the first piston, into the second pressing chamber beyond the second piston; in this stage the material is rolled over and re-layered. The second piston, after closing its opening, then advances, while the first piston retreats to its starting position. The pressure in the precompression chamber (1) can be accurately regulated and the squeeze-drying is virtually continuous.

Title: Intermediate layers on non-catalytic material - in exothermic reactor columns reduce excessive temp. rises
Inventor: EIGENBERGER GERHART DIPL ING D
IPC: B01J8/00
Filed: 1980-12-24
Abstract: In exothermic reactions between liq. and gases on catalytically acting fixed bed fillings in tubular reactors, where reaction enthalpy is mostly removed by the gas stream, the bed of catalyst or of material contg. catalyst is interrupted by layers of material with no catalytic effect. The catalytically neutral material may be the catalyst carrier itself, but is pref. Pall rings, Raschig rings or saddle bodies, so dimensioned that catalyst cannot penetrate. A filling with 50cm. layer of Pall rings, each 15 mm long, alternating with 1 metre layers of catalyst kept the temp. of a known reaction below 300 deg.C, whereas over 500 deg.C had been recorded in the uninterrupted catalyst body. Useful for high pressure hydrogenation with gas fed through external coolers, and reduces the incidence of uncontrolled temp. rises which can damage the catalyst.

Title: Discarding-sabot projectile
Inventor: GLEICHAUF WINFRIED ING GRAD
IPC: F42B14/06
Filed: 1981-02-20
Abstract: A sub-calibre discarding-sabot projectile (1, 2), which can optionally be constructed as a fin-stabilised or spin-stabilised projectile, is proposed. This projectile is based on the object of constructing means for automatically uncoupling the discarding sabot (3) from the projectile (2) after it leaves the weapon barrel, in a manner which is simple, reliable and additionally cost-effective. This is achieved in that a sleeve (4c) is mounted centrally in the discarding sabot (3), which sleeve (4c) has a central hole (4d) pointing in the direction of the tip of the projectile. Said hole (4d) together with a corresponding bolt (5) which is mounted in the projectile (2) forms a press connection. During firing, an axial relative movement, which is produced by the inertia force, of the bolt (5), which is connected to the projectile (2), takes place with respect to the sleeve (4c). A cone (5a) which is arranged on the bolt (5) in this case at the same time bursts open the sleeve (4c) at axial and radial weak points (4e, 4f) which are provided specially for this purpose, so that the projectile (2) is separated from the discarding sabot (3) and from the sleeve (4c). <IMAGE>

Title: Method and device for opening and closing the doors of coking ovens
Inventor: BENDER MARTIN
IPC: C10B25/14
Filed: 1981-02-26
Abstract: In opening and closing, the coke oven doors (4), which can weigh 10 t and more, are released from their seat by means of a door lifting device (10) and then, after they have been cleaned and the pushing operation has been concluded, are accurately reinserted. During movement in the direction of the oven axis, the door lifting device (10) is aligned automatically and correctly in relation to the oven on the locking hooks (40, 41) projecting on both sides of the oven opening (3), ensuring that the door plug (5) enters the door opening precisely in the centre. Division of the door lifting device (10) into a door lifting frame (11) and a door lifting head (12) mounted in floating fashion therein guarantees that the parts supporting the coke oven door (4) can align themselves on the locking hooks (40, 41). This purpose is served by the centring frames (17, 18), which are introduced with their centring noses (55, 56) between the locking hooks (40, 41) in order to serve as a guide and centring means for the door lifting head (12), which advances further. The door lifting head (12) is guided both in the horizontal and in the vertical direction by the guide (54) and the slot guide (49). The movements are cushioned by means of a spring cup (62) with a spring (64). <IMAGE>

Title: Safety device for waste gas flow for a heating boiler with blast burner
IPC: F23M9/00
Filed: 1981-02-28
Abstract: The invention relates to a safety device for waste gas flow for a heating boiler with blast burner. It is known to incorporate in a heating boiler, as safety device for the waste gas flow, a flow shaft which connects the waste gas conduit of the heating boiler, opening into the stack, with a combustion air channel via which the blast burner draws in the necessary combustion air. According to the invention, the flow shaft is not a component integrated in the heating boiler, but instead is arranged between the heating boiler and a cladding housing surrounding the latter. In this way, heating boilers can be fitted at any time, even at a later date, with a safety device for waste gas flow using the flow shaft.
Patent DE-3110471-A1 (DE)
Inventor: KLIE JUERGEN DIPL ING DR
IPC: G03F3/08
Filed: 1981-03-18
Abstract: In the method for improving the drawing in colour image reproduction by partial electronic retouching, the trichromatic sampling of a colour component of the colour image provides the trichromatic components which are subjected to an analog/digital conversion and stored in the memory (1). With a coordinate probe (50, 51, 52), a retoucher will proceed in the same way as with a retouching brush. By means of the probe, the coordinates of a moving area on the image (surface of the brush) of a trichromatic component to be retouched as well as the number of correction steps by image point will be searched. For the marked correction area the corrections will be calculated point by point. The trichromatic components of the coloured image or of a coloured printing will be read in the memory (1) and modified to obtain the retouching effect under the control of a monitor (2). The individual values of the corrections for each correction step may be freely selected. By previously determining the modifications so that they decrease from the center towards the edges of the image (for example according to the Gauss distribution), there will be provided in the retouching area a retouching degree which increases or decreases progressively.

Title: Method and device for positioning equipment cable wires
Inventor: EDINGER EGON ING GRAD
IPC: H01R43/28
Filed: 1981-03-27
Abstract: When assembling complete equipment cables and cables fitted with plugs, the wires must be moved into a predetermined position at both ends in order to be able to connect them to the associated plugs or the like. DE-PS 2842342 has already disclosed a method and a device for laying wires in the corresponding gaps in a positioning comb, the gaps representing the nominal position. The actual position of the wires (2) is detected visually and is fed into a control circuit for positioning the positioning comb. The invention relates to the detection of the actual position of the equipment cable wires. The equipment cable wires (2) are detected on the basis of their coloured markings, and their present sequence is entered either manually via a keyboard or automatically via an electronic colour-detection system (8, 9) into the control circuit, as the actual position. The actual position of one of the two cable ends is preferably determined by making electrical contacts with all the cable wires. <IMAGE>

Title: Ballast for connection of a discharge lamp
Inventor: KERSCHER MAX
IPC: H05B41/298
Filed: 1981-03-27
Abstract: Discharge lamps are frequently connected to the AC voltage mains power supply via an invertor and a rectifier, the invertor operating at a frequency of at least 10 kHz. In consequence, the inductance which is required for current limiting can be kept low and a high light yield can be achieved at the same time. However, in this case, the waveform of the current taken from the mains power supply is highly non-sinusoidal. In order to avoid this, the current extraction has already been controlled using a two-point regulator to which the mains power supply half-cycle is supplied as the required value and the lamp current as the actual value. The modulation of the lamp voltage which occurs in this case with the mains supply voltage is avoided as a result of the invention. <IMAGE>

Title: Mechanical direction indicator for two-wheeled vehicles, three-wheeled vehicles, in particular bicycles
Inventor: NUEBEL KURT
IPC: B62J6/00
Filed: 1981-04-14
Abstract: The invention relates to a mechanical direction indicator for two-wheeled vehicles, three-wheeled vehicles, in particular bicycles. Riders of two-wheeled vehicles and three-wheeled vehicles are obliged to indicate changes of direction to other road users. For the most part, this previously took place by stretching out the arm in the desired direction of travel; the resultant necessity to steer with one hand increases the risk of accidents. By fitting the mechanical direction indicator, it is possible to indicate changes in the direction of travel without adversely affecting the steering capability. The mechanical direction indicator comprises an attachment plate, hanging down from each of the ends of which is a movable signalling disc. Using Bowden cables which lead from the signalling discs along the vehicle frame to the handlebars and end there in pulling levers, the signalling discs can be moved (flashed) by repeated pressing of the pulling levers, or can be held in the deployed position by constant pressing of the pulling levers (see drawing). The attachment plate can be easily mounted retrospectively, using attachment screws, on the spars of the luggage carrier of two/three-wheeled vehicles. <IMAGE>
Patent DE-3118838-A1 (DE)
Title: Photoelectric switching device
Inventor: YORIFUJI YUKI
IPC: G01V8/12
Filed: 1981-05-12
Abstract: A photoelectric switching device is specified which has a built-in light source component having an oscillator and a removable light source circuit which is operated by the output signal of the oscillator, and having a removable light source which emits light upon reception of the signal from the light source circuit, a light receiver component having at least one photoelectric transducer for converting the light signal impinging thereon into an electrical signal and a signal processing component for processing the signal based on the converted electrical signal, and an auxiliary component for controlling the mode of operation of the built-in light source component and of the light receiver component, this signal processing circuit having a D flip flop, into which the input data based on the electrical signals are input by transmitting the output signals of the oscillator as signal pulses to the D flip flop via a reversible invertor. In this arrangement, the data signal is read into the D flip flop synchronously with the oscillation of the built-in oscillator (8). The oscillation frequency of the oscillator is locked in by the signal of the impinging light. Since the D flip flop is controlled by clock pulses from the built-in oscillator, undesired parasitic signals due to scattered light and the like are eliminated even when the light source and light receiver are arranged separated at a large distance.
