Abstract: The container consists of a container body with a hanging device. According to the invention, the container body 1 has a screw clamp-type fastener formed by a central limb connected to the container body 1 and two outer limbs 4, 6, one of which bears at least one clamp screw 14 which acts against the other outer limb. For the longitudinal adjustability of the central limb, the fastener is formed by two angle pieces 2, 3 each having an outer limb 4 and 6 respectively and each having a central limb 5 and 7 respectively, the latter being displaceable relative to one another. In the case of strip-shaped central limbs 5, 7 with elongate hole 12 and 13 respectively, the container body 1 and the angle pieces 2, 3 can be connected to one another and fixed relative to one another by a screw 8 which is inserted through the elongate holes 12, 13 and enters into the bottom 9 of the container body 1, it being possible for the angle pieces 2, 3 to be moved into a bridge position for the outer limbs 4, 6 to grip around thick objects or into an LL position for gripping around thin objects by turning one angle piece about the screw 8 relative to the other angle piece. The spacing of the outer limbs 4, 6 from one another depends on the position of the screw 8 in the elongate holes 12, 13. For repositioning the clamp screws 14, they bear holding plates 15 which can be unscrewed. <IMAGE>

Title: Liquid-outlet-securing device in the region of the piston rod guide on the pull-back cylinder of a metal-forming machine tool
Inventor: TRISSNAK KARL
IPC: B21J7/40
Filed: 1986-10-24
Granted: 1987-08-27
Abstract: There is a piston rod guide on the pull-back cylinder (3) of a metal-forming machine tool, in the case of which the pull-back cylinder (3) supports at its lower end two guide parts (1, 2), which are arranged with an intermediate space (18) and enclose the piston rod (6) with passage bores (7, 8) in a sealing manner, and a movable valve element (11) which is arranged in the intermediate space (18) rests on the passage bore (8), which acts as a valve face, of the lower guide part (2) in the closed position. In this arrangement, it is desirable for the valve element to seal off the lower passage bore in a reliable fashion even when there is a rapid and sudden flow of oil. This is achieved in that the valve element takes the form of a closing flap (11), which at one end is rotatably mounted (4, 13) and is arranged so as to be inclined upwards towards the piston rod (6), and which in the closed position rests above a bead (14) which projects vertically in relation to the surrounding regions of the lower guide part (2). The closing flap, which moves towards the lower open passage bore, is acted upon by the incoming flow of oil, which presses the closing flap downwards onto the closing flap seat in the closed position. <IMAGE>

Title: Explosion chamber
IPC: B21D26/08
Filed: 1987-03-31
Granted: 1987-12-10
Abstract: Explosion chambers are known today and serve for processing metals by exploding. These explosion chambers are very difficult to place under an adequately great vacuum in order consequently to make possible the treatment also of complicated, in particular fibrous, metal or ceramic powders. In order to be able also to carry out the manufacture of multi-layered thin sheet or foil coatings, in particular with fibrous structures, in an explosive manner, it is proposed to insert into the first explosion chamber a second explosion chamber which can be placed under a considerably greater vacuum.

Title: Gas bottle valve
IPC: A62C37/36
Filed: 1989-03-22
Granted: 1990-07-26
Abstract: The gas bottle valve (1) in the form of a rapid-opening valve has pipe pieces (3, 9, 33, 49) arranged in a cross-shaped manner. Arranged in one connection pipe piece (33) is an electromagnetically actuable pressure-reducing valve (41). This connection pipe piece (33) is constantly connected to a bottle pipe piece (3). On opening of the pressure-reducing valve (41), the extinguishing medium passes out of a container via the bottle pipe piece (3) to a release cylinder (22). This pivots a locking lever (12) which is positionally locked by articulated-lever action. As a result, the closing body (6) pressed against the valve seat (5) is freed and the pressure of the extinguishing medium can automatically lift the closing body (6) off the valve seat (5) so that the extinguishing medium can pass to the envisaged place via a discharge pipe piece (49). <IMAGE>
Patent DE-3915082-C1 (DE)
IPC: C02F11/13
Filed: 1989-05-09
Granted: 1990-09-27
Abstract: Sewage sludge passes through a viscous plastic phase between about 50 and 60 % dry matter content during drying. As at this consistency drying in a contact drier is not possible, mechanically dewatered sewage sludge has been first brought to a dry matter content of about 65 % by admixture with finished material, and the resulting mixed product fed to the contact drier. A very large amount of material is returned, causing a significant expense for marginal installations. With convective drying, e.g. in a belt drier, such back-mixing may be avoided, as the sticky consistency of the sludge has a less interfering effect here. Convective drying however has a high heat requirement and requires great expenditure for waste gas purification. According to the invention, mechanical dewatering of the sewage sludge is followed by a predrying in the contact drier. This is stopped before the product reaches the viscous plastic phase. In a process in which the final drying is likewise carried out in a contact drier, the predried intermediate is brought to a dry matter content of approximately 65 % by admixture of a relatively small quantity of final product. The viscous plastic region is thus passed over, and the final drying in the contact drier is possible without difficulty. In another process according to the invention in which the final drying is carried out in a belt drier, the intermediate is granulated without back-mixing with the final product and applied to the belt drier. In the belt drier only a relatively small quantity of water remains to be evaporated. The area of application is the drying of sewage sludge to a dry matter content substantially over 65 %, in particular over 90 %.
