Title: Clamping cylinder with safety nut
Inventor: STEITZ HANS
IPC: B25B5/06
Filed: 1987-12-07
Abstract: The clamping cylinder described is preferably used in hydraulic clamping systems for NC machine tools. It is of particular significance when the workpieces are clamped on pallets which have to be separated from the hydraulic pump for introduction into the machining space of the machine tool. With the cylinder described, monitoring of the clamping forces is not necessary as a pressure loss in the hydraulics system does not result in a change in the clamping force.

Title: Process for producing blocks
Inventor: BACHER ERICH
IPC: B28B23/18
Filed: 1988-05-26
Abstract: The invention relates to a process for producing blocks from a raw mixture rendered porous, which is prepared from a binder, water, a granular aggregate and additives in pourable form, foam being added to the raw mixture or produced in the latter, and the raw mixture being formed into a strand and heated as a strand for strengthening, after which blanks are successively cut off from the strand, transported into an autoclave and autoclaved there. To produce reinforced blocks, it is provided that a reinforcement in the form of straight rods is introduced into the blanks whilst their composition is still in a pasty state, in the longitudinal direction of the strand.
Patent DE-3819294-A1 (DE)
Title: Method and associated apparatus for drying or heating flexible or solid articles using flexible, easily movable air chambers with simultaneous removal of the condensate
Inventor: REENTS HEINRICH PROF DR ING
IPC: F26B25/06
Filed: 1988-06-07
Abstract: The dryers used today in private households and industrial plants are relatively large and heavy. They have an invariable spatial volume, they are not portable and not compact. Moreover, such dryers are not exactly reasonably priced. The drying method presented in this patent is based on the use of a flexible enveloping surface. Here, the system works on the counter-current and co-current principle. The flexible envelope has a flexible drainage channel for the condensation water. Drainage into a container is possible. The heat generator is protected from water by discharge devices. These discharge devices additionally have the function of providing an intense mixing of the airstream. They make possible the elimination of temperature peaks. The supporting frame of the flexible envelope is dismountable, so that the system components, consisting of the flexible envelope, the heat generator, the drying stand and, if necessary, the condensate chamber constitute a very compact, portable unit. The heat generator can be mounted above, below or to the side of the objects to be dried/heated. By virtue of the flexible envelope, an almost balanced temperature structure results in the chamber.

Patent DE-3826691-A1 (DE)
Inventor: UCHIDA MASAKI
IPC: A46B11/02
Filed: 1988-08-05
Abstract: A liquid applicator or writing instrument for forcibly supplying a liquid (3) having a relatively high viscosity from a liquid reservoir (4) to a liquid-application member (33) is operated by rotating a control knob (28) to axially move a plunger (7) forward in the liquid reservoir (4) to force the liquid (3) contained therein to be supplied to the liquid-application member (33). The control knob (28) is rotatable in only one direction, while the plunger (7) is prevented from being moved forward when the control knob (28) is axially pushed forward. Consequently, the liquid (3) is forcibly supplied to the liquid- application member (33) only when the control knob (28) is rotated in the correct direction so that the liquid (3) is prevented from being forcibly supplied to the liquid-application member (33) when the control knob (28) is axially pushed forward by accident. <IMAGE>

Title: Device for measuring angles of rotation
Inventor: KIPP JOHANN-CARSTEN DR ING
IPC: G01D5/02
Filed: 1988-10-20
Abstract: A description is given of a device for measuring angles of rotation of two parts which can move relative to one another and are at a predetermined axial separation, with the aid of a helical surface which is concentric with the axis of rotation. The helical surface is formed by a helical spring which is firmly coupled at one end to one of the parts and supports a measuring member which moves with axial change in the length of the spring and to which a ranging sensor (range finder) is assigned. The other part has at least one clamping member which engages in the turns of the spring and by means of which a change in length of the spring and thus an axial movement of the measuring member is produced upon the occurrence of a relative rotation between the two parts. The measurement device is distinguished by simple components in conjunction with a freedom from play which is easy to achieve.

Title: Web drying partic. for paper or cardboard - by passing drying air blown and extracted at fourdrinier zone to prevent lateral streams of moist air
Inventor: STURM WOLFRAM
IPC: F26B13/16
Filed: 1989-07-07
Abstract: To dry a moving web, partic. of paper or cardboard, drying air is delivered (61) to be blown into the fourdrinier zone (S) in an equal distribution across the machine width, and then sucked out (63) from the zone (S). The air drawn out (63) from the fourdrinier zone (S) is used as recirculating air to be blown back at the web (9). The drying air is blown (48) into the zone (S) where the web is in contact with the two adjacent drying cylinders (12, 13), and blown air can be delivered through the stabiliser (30) which holds the web (9) by suction to the porous carrier (10). Drying air is extracted from the zone (S) through the suction guide rollers (21, 22) where the blown air is delivered to the web (9) while carried by its support round the suction guide roller (21, 22), or external suction chambers are used. ADVANTAGE - The system gives added protection against lateral flows of moist air, and reduces energy consumption in drying the web.
