Patent DE-3324799-A1 (DE)
Title: Improvement of the roller chain, roller chain variants and application techniques
Inventor: STEUER WILLI DIPL ING
IPC: F16G5/16
Filed: 1983-07-09
Abstract: The addition contains the improvement of the roller chain according to P 3201351.5 and roller chain variants and application techniques. By positioning the chain link pressure flanks D with respect to one another different radii R of curvature can be produced between the deflections around a closed roller chain, in which the flanks D lie on one another and the roller chain is tightened up (sheet 2). In the sphere of application, for example in planetary gearing, this means high contact pressure with low flexing work. If the pressure flanks D already bear on one another when the roller chain is in the circular state, the roller chain forms a gear rim. One roller chain variant provides for hollow links, which are aligned on a longitudinally divided, dual-strand studded belt and the open sides of which point to the belt flanks. For coupling two gears of a gear train the roller chain as coupling unit is arranged together with two pulleys supported opposite one another in a web between the gears. The space required for this gear chain and the cost are lower than for conventional ones. For driving conical pairs of sheaves a roller chain variant has wedge-shaped cross-section and makes the frictional connection by means of laterally projecting cams. <IMAGE>

Title: Filter pipe for a well
Inventor: HOPF KLAUS-DIETER
IPC: B01D29/00
Filed: 1983-07-18
Abstract: In a filter pipe for a well having a filter pipe made of plastic having filter slots running in the peripheral direction and having ribs arranged on the outer peripheral surface of the filter pipe running in the longitudinal direction, a permeable layer of gravel is arranged on the outer casing surface of the filter pipe, the pieces of which gravel are firmly fixed to each other and to the outer casing surface of the filter pipe. The gravel layer avoids damage of the regions of the filter pipe between the filter slots during transport and installation, while at the same time, as a result of the filter slots, a compensation of the different thermal expansions between the gravel casing and filter pipe is achieved and thus the gravel layer is prevented from falling off the filter pipe. <IMAGE>

Patent DE-3342231-A1 (DE)
Title: Hot melt adhesive application device
Inventor: KRATZSCH ACHIM
IPC: B42C9/00
Filed: 1983-11-23
Abstract: The device of the invention is preferably for the application of hot melt adhesive to the backs of inner books or the like by means of application rollers which roll on the back of the inner book to be glued and thus apply a film of adhesive. The aim of the invention is to minimise machine stops, due to the adhesive temperature falling below the required value, in the heating-up phase after work breaks, and to improve the quality of the adhesive joints. For this purpose an intensive mixing of the adhesive is necessary, in order rapidly to reach the required temperature of the adhesive in the region of the adhesive application roller. According to the invention the object is achieved when an apparatus for regulating the required temperature for the adhesive in the region of the adhesive application rollers is provided. When the adhesive temperature falls below the required value, the adhesive application rollers are driven by a separate drive motor until, after reaching the required temperature as quickly as possible, the adhesive binding machine is brought into operation. For this purpose an electromagnetic switch coupling is provided for connecting the single-revolution shaft of the machine with the drive shaft for the adhesive application rollers in the correct time cycle. <IMAGE>

Title: Heel part for a safety ski binding
Inventor: JUNGKIND ROLAND
IPC: A63C9/084
Filed: 1984-02-25
Abstract: In order to allow a compact design and low operating forces despite high retaining forces in a heel part for a safety ski binding, the sole hold-down is constructed as a part which can be pivoted separately in relation to the bearing block and whose pivoting is monitored by a spring-loaded, two-armed lever which can likewise be pivoted separately. By suitable selection of the transmission of this two-armed lever which is possible due to the kinematic uncoupling of the sole hold-down and the heel block, an appropriately small operating force can be maintained despite high retaining force.

Patent DE-3436424-A1 (DE)
Title: Device for producing highly superheated free liquid jets
Inventor: WILDGEN ANDREAS DIPL ING
IPC: B05B1/02
Filed: 1984-10-04
Abstract: The nozzle (Fig. 1) for producing a highly superheated free liquid jet must have a sharp-edged nozzle inlet (1) so that the flow separates from the nozzle wall as early as possible. The nozzle inlet must be designed in such a way that it is raised against the flow direction in order to produce as large a vena contracta as possible. The axial part of the nozzle (2) (e.g. the bore) must be kept as short as possible so that the free jet can no longer touch the nozzle wall. This can be achieved, for example, by a discharge cone (3). A smoothing section (e.g. with flow baffle plates) has to be provided upstream of the nozzle so that the liquid flows axially against the nozzle. In front of the nozzle the feed cross-sections have to be so large that no vaporisation occurs in front of the nozzle. The nozzle can be of circular, annular or slot-shaped design. With this device it is possible to clean surfaces with superheated water which are at a distance of up to 1 m from the nozzle. Conventional high-pressure cleaning appliances can be used to produce the hot pressure water. Since many bubbles are produced when the jet strikes a solid surface, which expand very rapidly (explode) on account of the high superheating, the jet is finely atomised. This feature can be useful, e.g. in burners or air humidifiers. <IMAGE>

Title: Device for monitoring the speed of rail-bound vehicles
Inventor: STRUB DIETER
IPC: B61H7/04
Filed: 1984-10-23
Abstract: In order to achieve a firm but gentle emergency braking, with no adverse effects for personnel and material, on rail-bound vehicles, in particular storage and retrieval units for high-bay warehouses, the travel speed is repeatedly monitored towards the end of the travel way. A trigger lever (19) which is suspended in oscillating fashion on a wheel axle (15) passes with a roller (21) a deflection ramp (22) and, at its end section, a narrow passage (b). When an admissible speed, which is related to a specific location, is exceeded, the trigger lever (19) strikes, thanks to its mass inertia, against a stop (26), is swivelled in this process and thus turns a wheel bearing bushing (18) in which the wheel axle (15) is eccentrically attached. As a result, the vehicle component (7) which loads the wheel (12) is lowered to such an extent that a brake shoe (16) which is connected to it is pressed onto the rail (13) by the weight of this vehicle component and the vehicle is braked. <IMAGE>

Title: Attachment for cabinets, in particular show cabinets
Inventor: HACKENBERG DIETER
IPC: E05F1/10
Filed: 1985-02-01
Abstract: In an attachment for show cabinets or the like, a bent panel is used which is pivotable about a horizontal axis of rotation and can be pivoted between a closed position and an opened-up position and has upwardly projecting supports made of a hollow profile. For this purpose, a joint head which fastens the panel is mounted pivotably inside the upper end of the support and bears a connection arm which points towards the inside of the profile in the closed position and on which acts a power accumulator which is arranged inside the profile and is supported at the other end on the support via a stationary hinge point. The power accumulator facilitates the movement of the panel into the opened-up position and, during this movement, its coupling joint on the connection arm passes through a circular arc-shaped joint path on which it reaches an apex position where the line of application of the power accumulator lies approximately tangentially to the joint path. In order to allow convenient and rapid installation and removal of the power accumulator, it is proposed to construct the lower elbow piece of the coupling joint to be smaller between its end position and apex position than the upper elbow piece which is located between the apex position and the upper end position of the coupling joint. Furthermore, in this end position the clear remaining width between the free end of the connection arm and the opposite profile wall is dimensioned to be greater than the maximum cross-section of the power accumulator.

IPC: G08B21/10
Filed: 1985-07-05
Abstract: In a method for monitoring the state of wear of materials such as refractory linings of metallurgical vessels or of brake linings, a line is inserted into the material to be monitored. The state of wear is inferred from the sudden change of a measurement quantity transmitted through the line. The measurement quantity is changed by an interruption in the line. An optical waveguide is preferably used as the line, and a signal is generated when the transmission suddenly stops.
