Title: Joint slab for expansion joints on buildings
Inventor: SCHOECK EBERHARD DIPL ING
IPC: E04B1/00
Filed: 1987-12-24
Abstract: An expansion joint on buildings, use is made, in order to avoid the transmission of forces between buildings or building parts and for the purpose of sound and/or heat insulation, of joint slabs. During building, such a joint slab fulfils an additional task as shuttering, spacer or the like, in that it is formed by a plastic, box-shaped hollow profile which forms one or more chambers, said hollow profile being produced by extruding, blowing or deep-drawing. The joint slab can be reinforced by transverse ribs, which pass through the hollow profile, and may further be provided, on at least one narrow side, with a connection profile.

Title: Method of determining changes in the O2 content of dust-laden drying vapours
Inventor: SCHARF HANS-JOACHIM DIPL ING D
IPC: G01N25/54
Filed: 1988-01-27
Abstract: The method of determining changes in the O2 content of dust-laden drying vapours on a chimney for vapours has the object, depending on the changes in the O2 content in the drying air, to make the operation such that ignitions and inflammations of the electrofilter are safely avoided. This object is achieved by measuring the temperature of the H2O dew point of the vapours (3) using a probe (6) at at least one measurement point within the chimney for vapours (1) (Fig. 1) over a specific period of time and determining the O2 concentration in the vapours (3) via the H2O partial pressure. The probe (6) is brought to a measurement point (7, 10, 12 or 13) within the cross-section of the opening (2) of the chimney for vapours (1). Measurement points are provided in a plurality of planes (8, 9 or 11), in particular horizontal planes, of the cross-section of the opening (2). The probe (6) has a measurement window which has associated with it at least one guard to protect it from dust deposition or water. The guard is constructed in the shape of a roof. <IMAGE>

Abstract: A hollow cylindrical rotary drive shaft (3) that is available as a propeller shaft in a vehicle or the like. The drive shaft (3) has solid portions (4) at the opposite ends of a hollow portion (5), and it can be supported at the solid portions. The hollow portion (5) has a sole primary bending characteristic angular frequency of 500Hz or higher and a ratio (t/D) of a wall thickness (t) to an outer diameter (D) of 0.06 or less. A vibration suppressor (6, 8) made of elastic material is pressure- inserted (6) into this hollow portion, or it is tightly fitted around (8) an outer circumference of the hollow portion. By presetting a sole primary bending characteristic angular frequency of the hollow portion large, primary bending resonance of the drive shaft can be effectively absorbed by the vibration-suppressor in a region where a frequency is high and a vibration energy level is high. <IMAGE>

Title: Longitudinally mobile carriage for a mast foot anchor on a sailboard
Inventor: FRANK DIETER
IPC: B63B35/79
Filed: 1988-04-20
Abstract: Longitudinally mobile carriages for a mast foot anchor are known, in which an anchor pin is held in a vertical bore in the carriage via a safety spring clip. When a force is exceeded, the anchor pin connected to the mast is released. The anchor pin can be held non-releasably in a second functional position. In this position, however, the spring clip can be entrenched in the carriage in such a way that the anchor pin is nevertheless no longer released even in the first functional position when the spring force is exceeded. In order to overcome this disadvantage, it is provided that the safety spring clip (13) is supported in the first and second functional positions at different points on the carriage (1), that is to say at locations which are not congruent in plan view. The carriage is suitable for a rig. <IMAGE>

Title: Device for receiving flat workpieces
Inventor: BIERLMEIER JOHANN
IPC: B65H3/58
Filed: 1988-06-03
Abstract: Devices for receiving flat workpieces serve for automation of work operations, in particular in the manufacture of ready-made clothes. The singling of workpieces in connection with the finishing of workpiece stacks is made more difficult by the occasional sticking together of the workpieces which have been deposited one above another. In order to provide a remedy in this case, it is known to make use of stripping brushes and blowing nozzles. A further possibility for assisting singling is proposed, in which vertically aligned needles (1.2, 3.4) are provided in the immediate vicinity of the workpiece gripper (3.2). In needle singling from below, they penetrate the workpiece stack (2) from the bottom to the top. In needle singling from above, they are active as push needles (3.4) which, when a workpiece grasped by the workpiece grippers (3.2) is raised, push off the workpiece lying below which is perhaps adhering to it. <IMAGE>

Filed: 1989-03-03
Abstract: A pitch feathering system (Fig 9) for propeller blade 42, utilizes a counter-weight 92 linked 94A, 94B to the blade 42. The weight is constrained to move, when effecting a pitch change, only in a radial plane and about an axis 102 which rotates about the propeller axis 58. The system includes a linkage 94A, 94B allowing the weight to move through a larger angle  theta  than the associated pitch change (???) of the blade 42. In one practical embodiment (Figure 10) variable pitch blades 42 are linked by a unison ring 114 and a plurality of counter-weights 92 are linked to the ring 114 to change pitch via the ring under the action of antifugal force. In an alternative embodiment (Figure 16) counter weights 136 pivot about axes tangential to a circle about the axis of rotation of the propeller, gears 138A, B transmitting pitch change movement to blades 42. The pitch change mechanism can be applied to the counterrotating propeller blades of a propulsor including interdigitated turbine blades (Fig 2). <IMAGE>

Title: Heat pipe
Inventor: HOERMANSDOERFER GERD
IPC: F28D15/02
Filed: 1989-03-20
Abstract: The invention relates to a thermal syphon and a heat pipe having special working liquids which can be used in principle over the entire temperature range. However, in this case the range between -10 and +40@C is especially preferred, because so far no optimum working liquids have been available here. The heat-transporting capacity of the known working liquids of methanol and ethanol is not very high. The temperature range mentioned above is too low for water, which is overwise the ideal working liquid. The invention makes available a heat pipe having different working liquids based on azeotropic mixtures which not only cover a wide temperature range, but at the same time also have a very high heat-transporting capacity.

Abstract: A precision chuck for a tool, in which a chuck body 1 accommodates a chucking sleeve 6, in which a piston 7 actuating the chucking sleeve 6 is displaceable in a reciprocating manner by a length of chucking travel, and in which an actuating device 11 acts symmetrically on the piston 7 and displaces the piston 7 by screws 12, 13 against a chucking force by the length of chucking travel. It is desirable here for the symmetrical loading of the chucking sleeve to be realised mechanically and in a simpler manner. This is achieved by the actuating device being formed by a double-bevel bolt device 11 and by the double-bevel bolt device 11 acting on the piston 7 and being displaceable by the screws 12, 13 against the chucking force by the length of chucking travel. The mechanical and symmetrical loading of the chucking sleeve is obtained in the simplest manner by the double-bevel bolt device acting on the piston. <IMAGE>
