Title: Duct branching
Inventor: BECKER JOERGEN
IPC: F23J11/00
Filed: 1987-08-14
Abstract: In the case of a bypass duct branching vertically downwards from a horizontal gas duct, dust deposits, which are detrimental to operation and are caused by a dust-charged gas flow, occur on a shut-off device located in the bypass duct. By means of the novel duct branching, no dust deposits are to occur and, at the same time, its horizontal part is to be shortened in length. A portion of the inlet end of the bypass duct (2) is divided up into at least two separate sub-ducts (4) which penetrate, in a grid-like manner and vertically with respect to the entire arrangement, the gas duct (1) in a cross-sectional plane (E) of the duct and form through-ducts (5) in the gas duct (1), the sub-ducts (4) located in the gas duct (1) exhibit, in each case on at least one sub-duct wall (6'; 6'') essentially parallel to the direction of the gas flow, an opening (7) which is in the form of a slot in the vertical direction and is intended for the passage of the gas out of the gas duct (1) into the sub-duct (4) of the bypass duct (2), and arranged on each sub-duct opening (7) is a shut-off flap (8) which can pivot about a vertical axis of rotation, belongs to the shut-off device and is intended for closing the sub-duct opening (7) or the through-duct (5), and the size of which is determined by the cross-sectional surface area of the through-duct (5). The main application area is the use in front of a system for the selective catalytic reduction of NOx. <IMAGE>

Patent DE-3740014-A1 (DE)
Title: Blocking apparatus for a container conveyor of a container treatment machine
Inventor: GAU GEORG
IPC: B65G47/88
Filed: 1987-11-26
Abstract: The blocking apparatus has a movably mounted blocking element which is arranged laterally adjacent to the conveyor belt, which can optionally be fixed in a position which blocks the conveying path between the lateral guides or can be transferred into a position which unblocks the conveying path and which is mounted so as to be movable along the conveying path and is provided with a damping organ which inhibits its movement in the conveying direction and has a pressure medium cylinder and a throttle valve. The pressure medium cylinder is constructed so as to be of double-acting type and can move a control element between an end position, situated upstream, in which the conveying path is unblocked and an end position, situated downstream, in which the conveying path is blocked. The blocking element is mounted in an elongate hole of the control element and can be moved between a freely rotatable position and a blocked position as a result purely of the movement of the control element between the two end positions. The blocking element thus does not require any second pressure medium cylinder for blocking the blocking element or any flexible lines for the single pressure medium cylinder which is fixedly arranged. <IMAGE>

Patent DE-3805531-A1 (DE)
Title: Method for conveying powder and apparatus for carrying out this method
Inventor: NAGORSKI ROMAN DIPL ING
IPC: B65G53/26
Filed: 1988-02-23
Abstract: In the conveying of fluidised powder, in particular for powder coating of articles, it is disadvantageous that, for the purpose of fluidising, a relatively large quantity of air must continuously be introduced into the supply container for the powder, which quantity of air is required only to a relatively small degree for the further transport of the powder. The object consists in avoiding these disadvantages. In the method according to the invention, the problem is solved in that the powder is sucked up by means of a partial vacuum and then conveyed further by a flow of propellent, the partial vacuum also sucking up the fluidising flow of air. The partial vacuum is produced by a propelling nozzle. The invention is used for conveying powder in general, and, in particular, also for powder coating. <IMAGE>
Patent DE-3806718-A1 (DE)
Title: Pressure-operated friction-disc clutch or brake
Inventor: WOLF ANDREAS
IPC: F16D25/063
Filed: 1988-03-02
Abstract: Pressure-operated friction-disc clutch or brake with a piston-cylinder actuating device (1, 2) and a diaphragm spring (3) arranged between the piston (1) and a pressure plate (4) of the friction-disc clutch, the contact surfaces (11, 41) for the diaphragm spring (3) being arranged in principle at right angles to the axis (A) of the friction-disc clutch. To influence a force characteristic (K1, K2) during the engagement of the friction-disc clutch (4, 5, 6, 7), at least one of the contact surfaces (11, 41) has a contour (R1, R2, R4, 13) of defined shape which extends in the radial direction and deviates from the right angle. By virtue of the change in the attitude angle and the rolling of the point of contact of the diaphragm spring along the contact surface and the associated shortening of the lever arm (H), it is possible to achieve any desired pressure characteristic with a diaphram spring of standard configuration. The contour on the contact surface of the piston (1) and/or of the pressure plate (4) is simple and inexpensive to make. <IMAGE>
Patent DE-3810570-A1 (DE)
Title: Multiple fastening device for trees on stakes
Inventor: DRIGNATH ROLAND
IPC: A01G17/12
Filed: 1988-03-29
Abstract: The invention relates to a clip-like securing means of various embodiments which, by the installation of up to six strutting bars which can screw-connected and brought into connection with stakes, provides a planted tree which is exposed to strong wind/storms with the necessary stability. The former practice of trees being tied with thin cables and similar auxiliary means, of which the ties, wearing through and/or rotting in a comparatively short period of time when subjected to strong wind/storm loading, can now be dispensed with. The round bars consisting of plastic for the strutting purposes are, on the one hand, introduced in a screw opening of the tree securing means and, on the other hand, are fitted on wooden stakes either in a seamless manner or via a screw-receiving means which is fastened on the stake by a suitable wood screw (if appropriate also by driving in nails). This achieves a self-contained and force-compensating unit. Plastic stakes are coupled to the strutting bar by screw-in openings made during production. The tree securing means, which may be produced, according to the invention, in two sizes, are compensated by inserts in the case of intermediate sizes. Free screw-in attachments of the tree securing means may expediently be fitted with adaptors which are provided with information plates.

Title: Sound-absorbing pipe lead-through
Inventor: LIMBERG WERNER
IPC: F16L55/033
Filed: 1988-04-28
Abstract: Sound absorption in the case of pipe lead-throughs through walls of ships was unsatisfactory up until now as a result of the conventional, low thickness of insulating, non-metallic intermediate layers. The invention provides a sound-absorbing pipe lead-through, in the case of which a radial interspace between the pipe and a sleeve, which encloses the pipe, of at least 25 mm is filled with an elastomer which is connected to the metallic surfaces by vulcanisation. In a preferred embodiment, the pipe (11) exhibits ribs (19), and the sleeve (13) has ribs (20), the thickness of the elastomeric material (18) being at least 25 mm in every direction. <IMAGE>
Patent DE-3815781-A1 (DE)
Title: Positioning and minimum-pressure safety valve
Inventor: DIMTER ERWIN
IPC: B23B31/30
Filed: 1988-05-09
Abstract: If workpieces for machining are inadequately clamped by fluidic media, because the requisite operating pressure is not reached, the workpiece to be machined can be thrown out in an uncontrolled manner by the engagement of rotating tools and can be damaged and can endanger the operating personnel. According to the invention, a minimum-pressure safety valve is intended to ensure that the feed of a machine tool only starts when the workpiece is firmly clamped by the fluidic media and that the feed is stopped if the clamping pressure drops below the requisite value during the machining. At the same time, the feed can be stopped at will by an impulse on the minimum-pressure safety valve without the speed control valve having to be actuated.

Title: Heat store, in particular for motor vehicle heaters fed by engine exhaust heat
Inventor: SCHATZ OSKAR DR ING
IPC: F02N19/10
Filed: 1988-06-06
Abstract: In a heat store, in particular a latent-heat store for motor vehicle heaters fed by engine exhaust heat, feed and drain lines (12, 14) traverse an insulating chamber (30, 30a) which serves the purpose of thermal insulation and is constructed between an inner heat store housing (10), which surrounds the core of the store, and an outer heat store housing (28). Inside this insulating chamber (30, 30a), these lines have an at least approximately vertical section (26) whose upper end is connected to the inner heat store housing (10) and whose vertical length, owing to the temperature gradient between the core of the store and the surroundings and the thermal conductivity of the transfer medium led through the lines, corresponds to the vertical extent of a blocking layer which produces the desired degree of insulation and is formed between the upper end of the approximately vertical section of the lines, which is connected to the core of the store and is therefore the warm end, and the lower end, which is connected to the surroundings and is therefore the cooler end. <IMAGE>
