Patent DE-3122278-A1 (DE)
Title: Tank
Inventor: POBLOTZKI JOACHIM DIPL ING
IPC: F17C3/02
Filed: 1981-06-04
Abstract: In a tank for the storage of liquefied gases at low temperatures, an intermediate area is formed between a steel inner tank and an outer wall and surrounds the inner tank, this intermediate area being filled with a bulk insulating material. Since this bulk material settles over the course of time, it was previously necessary to extend the intermediate area upwards above the inner tank and in this way to form a storage area for the bulk material. In order to reduce the structural height and use it more economically, it is proposed according to the invention to place the storage area no longer, as previously, above the intermediate area, but instead above the ceiling in the ridge area under the roof of the tank. <IMAGE>

Patent DE-3142215-A1 (DE)
Inventor: ERCKEL RUEDIGER DR
IPC: C13K1/02
Filed: 1981-10-24
Abstract: The continuous process for hydrolyzing cellulose-containing material (substrate) is carried out by sorption of gaseous HF in a sorption reaction (1) and subsequent desorption in n steps, which are carried out in n reactors which are separated from one another in a gas-tight manner. The substrate is introduced via a gas-tight valve into the sorption reactor (1), passes through this and then reaches consecutively, through gas-tight valves, a hold-up reactor (2) and the first (3c), second (3b), . . . nth desporption reactor, from which it is then removed. The desorption is carried out in each case by the action of one of the n inert gas streams on the substrate at different temperatures, the particular inert gas stream being enriched with the HF being liberated during desorption. The gas streams, which are enriched to different extents with HF, are allowed to act on the substrate in the sorption reactor (1) in such a manner that the gas streams of low HF concentration act on a substrate having a zero or low concentration of HF and thereafter the gas streams of higher HF concentration act on substrate having higher HF concentration. The total gas stream (8a) produced from the individual gas streams leaves, after completion of sorption, the sorption reactor (1) largely freed of HF and is either conveyed to the desorption steps after dividing up into individual gas streams or it initially passes through the last desorption step (3a) and is thereafter divided up and passed to the other desorption steps in order, after passing through the latter, to be returned to the sorption reactor (1).

Title: Method and device for emptying substrates in fungal cultivation, in particular in Pleurotus cultivation and storage containers for such substrates
Inventor: MADEJSKY MICHAEL
IPC: A01G1/04
Filed: 1982-02-19
Abstract: For mechanical emptying of a substrate for fungal cultivation into containers in such a way that optimum conditions result both for its introduction and storage, and transport which is as uncomplicated and gentle as possible is ensured, the substrate is added loose to the supply wheel of a ram-type press and pushed by its ram into a stiffened sack-like container placed in front of the press nozzle. This process is carried out in a device having a wide filling funnel, which serves for the relatively loose uptake of the substrate and in which is situated a slowly rotating conveyor wheel which conveys the detected substrate into a press channel, from where it passes into the outlet opening of the filling funnel and is pushed into a substrate container in compressed state by a ram. The containers used are rectangular, plastic-lined square baskets consisting of angular and flat sections, which can be provided with feet.

Title: Securing bolt which can be inserted from one side into through holes in components, as far as a stop
Inventor: LEITNER KAJETAN
IPC: F16B21/12
Filed: 1982-06-22
Abstract: A securing bolt which can be inserted from one side into through holes in components, as far as a stop, can be locked in its inserted position such that it cannot be pulled out and can be pulled out again from this side after unlocking. The securing bolt consists of a tubular piece with a securing piece which passes axially through the tubular piece, on the one hand projects axially out of the tubular piece on the side of the tubular piece facing the stop, for the purpose of operation, and, on the other hand, emerges radially from said tubular piece, through an aperture, on the opposite side of the tubular piece, in the locking position. The securing piece consists of a pin which essentially fills the tubular piece and, on its guide end facing away from the stop, is provided with a centrally running slot in which at least one locking bolt, which projects into the aperture, is supported rotatably on a shaft which passes through the slot laterally and is in each case located behind the aperture in the direction of the guide end. The pin can be pressed into the tubular piece against spring tension and, at the same time, pulls the locking bolt into the aperture. When the pin is pressed out under the influence of the spring tension, the locking bolt is moved out of the aperture and hence assumes the locking position.

Title: Laundry mangle
Inventor: MOELLER CLEMENS
IPC: D06F67/00
Filed: 1982-06-24
Abstract: The invention relates to a laundry mangle having a roller rotatable in a trough and having a laundry bearing plate located in front of the trough in the run-through direction of the laundry and a laundry reception plate located behind the trough. In hitherto known backward-running laundry mangles, there is the danger that an attendant's hands located in the immediate vicinity of the laundry run-through slit can be drawn into the run-through slit between the trough and the roller of the laundry mangle. The object on which the invention is based is to reduce the danger of accidents in backward-running laundry mangles. According to the invention, a laundry run-through slit located between the trough and the roller is covered, at its exit end assigned to the reception plate, with a deflector strip which deflects the laundry, and the deflector strip is guided in such a way that its distance from the roller is variable. The deflector strip according to the invention performs the function of a protective device, the mangled laundry no longer being received directly at the run-through slit, and the actual danger site between the roller and trough thus being made safe by the deflector strip.

Title: Method and device for feeding air into the interior of a hollow body when stripping it from the extrusion stem of an extrusion press
Inventor: RITTER WILHELM DIPL ING
IPC: B21J13/14
Filed: 1982-11-06
Abstract: In a method and a device for feeding air into the interior of a thin-walled extruded hollow body when stripping the hollow body from the extrusion stem of an extrusion press by feeding air through the extrusion stem, the air feed into the interior of the hollow body upon a change in rotational speed of the drive of the press or a change in the stroke rate of the extrusion stem should be effected proportionally to the continuous change in the rotational speed in order to avoid destruction of the hollow body or malfunctions. As shown in Fig. 2, this is achieved by virtue of the fact that a tachogenerator 1 mechanically coupled to the drive of the press and belonging to an electronic control 2 supplies a speed-proportional voltage which, after amplification, controls a proportional pressure setting valve 3, the outlet of which controls a pneumatic quantity 4 for the purpose of increasing the quantity. The air feed to the extrusion stem 6 at the respectively required time is here controlled via a 2/2-way valve 5 in a manner dependent on a disc cam driven mechanically with the drive of the press. The speed at which the air flows into the hollow body in is dependent on the stroke rate of the extrusion stem while the air quantity remains constant. <IMAGE>

Title: Compression control device
Inventor: WALZER PETER DR ING
IPC: F02B23/08
Filed: 1983-03-15
Abstract: A device for controlling the compression ratio of a multi-cylinder reciprocating piston internal combustion engine as a function of the load has a main piston (2) assigned to each cylinder (1), which slides in the cylinder and at its top dead centre encloses a combustion space (4) opposite the cylinder head (3), and a secondary piston (7), which slides in a secondary cylinder (8) arranged in the cylinder head and connected to the combustion space. This secondary piston can be adjusted in order to vary the volume of the combustion space as a function of the load of the internal combustion engine. In order to achieve a further improvement in the combustion conditions in the combustion space with a device of this type, especially during partial load states, it is proposed that the secondary cylinder (8) be arranged in the cylinder head (3) in such a way that in its position producing the smallest combustion space volume, the secondary piston (7) forms a squish gap (9) in relation to the main piston (2) standing at top dead centre, which gap produces a squish flow directed into the other combustion space (4). <IMAGE>
