Title: Method of closing hollow bodies gas-tight
Inventor: JANSSEN MANFRED DR-ING
IPC: B23K1/18
Filed: 1982-04-27
Granted: 1983-10-13
Abstract: The invention relates to a method of closing hollow bodies gas-tight, in particular tubes. In order to provide a method with which reliable gas-tight closing of hollow bodies is possible with simple means and in an energy-saving manner, it is proposed to carry out the method in the following steps:   a) applying a brazing metal to a longitudinally textured metal mandrel, the diameter of which is smaller than that of the hollow body to be closed, b) reducing the diameter of the hollow body at the end to be closed in several deformation steps, whose deformation parameters (degree of deformation, speed of deformation) as well as their time sequence are matched in such a way that the deformation temperature occurring is continuously increased up to a point above the melting point of the brazing metal and up to an inside diameter of the hollow body which is greater - at most 0.5 mm greater - than the outside diameter of the mandrel, c) pushing the mandrel into the hollow-body area deformed according to b), d) and if need be subsequently reducing the diameter of the hollow body while simultaneously also slightly deforming the metal mandrel.   <IMAGE>

IPC: B22D31/00
Filed: 1983-07-01
Granted: 1985-02-28
Abstract: A process for producing a casting mould with chemically bound moulding material using a pattern is intended to make it possible to forego the use of clay-bound sand, in particular for the mass production of cast members, and to provide a casting mould of adequate gas permeability, which is simple to produce, with a low level of consumption of moulding material, and inexpensive, and which also provides a high level of casting quality wth a low degree of environmental pollution. For that purpose, the moulding material which has become pourable or fluid due to the operation of casting a cast member is removed from a first casting mould comprising a single moulding material, whereas the remaining portion of the moulding material is left, and the hollow space formed when the pattern is re-fitted is filled with moulding material. In addition, the moulding material which has been reduced in strength may be also removed, being for example blown or brushed out.

Title: Symmetric rig
Inventor: PLICA PETER DR
IPC: B63B35/79
Filed: 1985-04-19
Granted: 1986-09-18
Abstract: The invention relates to cross frames of flexurally rigid, curved ribs, provided with a variable cross-section, for a rig which is symmetric to the longitudinal axis, can be rotated and tilted at the foot point and has a sail area which is of oval design in cross-section and is spread by mast-like spars, the straight, mast-like longitudinal spars being arranged in the region of the sail axis and cross frames being provided which run transversely to the longitudinal spars. Compared with known multi-piece cross frames, the advantages of one-piece ribs on the one hand lie in the quicker and simplified erection and dismantling of the rig. In addition, the trimming of known cross frames by means of tie members is dispensed with. The deformation of the cross frames as a result of wind pressure is reduced owing to the better rigidity of the ribs.

Inventor: BRUNNER RUDOLF
IPC: B23Q3/08
Filed: 1986-02-24
Granted: 1986-11-20
Abstract: The invention relates to a hydromechanical tool or workpiece clamping apparatus comprising at least one spring clamping cylinder connected to a release conduit and adapted to be hydraulically operated against a spring force to a release position, a pump connected to said release conduit and operable for a release operation, and a discharge conduit extending from said release conduit to a fluid reservoir and including a discharge control element for discharging the pressurized fluid from said spring clamping cylinder to said reservoir after deenergization of said pump. A known clamping apparatus of this type has a solenoid poppet valve disposed in said discharge conduit and operable to close said discharge conduit for the release operation and to be actuated to a flow-through position and maintained therein for the clamping operation. The solenoid valve is expensive and requires separate control means. In contrast thereto, the invention provides the use of a discharge control element in the form of a simple bypass shutter the flow resistance of which at a constant output flow rate of the pump is greater than the pressure required for overcoming the spring force in a release operation.

Granted: 1987-10-08
Abstract: In a draw key change gear which has four toothed wheels (71 to 74) mounted rotatably next to one another on the drive shaft (52) designed as a hollow shaft, two draw keys (81, 82), which are in each case assigned to two adjacent toothed wheels (71, 72 or 73, 74), are arranged axially one behind the other in the hollow shaft (52). The actuating members for the draw keys (81, 82) are in turn arranged coaxially with one another in the hollow shaft (52). The draw keys (81, 82) are formed by the pins which pass diametrically through the hollow shaft (52), which are merely loosely inserted in the actuating members (85, 88) and which are provided at their ends (82'), which come into engagement with the toothed wheels, with points which facilitate the introduction into axial grooves (93, 94) of the assigned toothed wheels. <IMAGE>

Granted: 1989-05-18
Abstract: A process for operating a calender (1) provides that, before the uppermost roll gap is closed, the upper roll (4) is preshaped to conform to the curvature of the uppermost intermediate roll (6). To carry out this process, the upper roll (4) possesses a roll jacket (21) which is penetrated by a non-rotating shaft (22) and has primary pressure zones (27) and secondary pressure zones (28). A pressure adjustment device provides for a pressure distribution for the pressure zones (27, 28) which produces a bending deformation of the roll jacket (21) independent of external forces stemming from the adjacent roll (6). Furthermore, the upper roll (4) has a heating facility which maintains the temperature of the upper roll at a predetermined level. This allows an improvement in the glazing process accompanied by simultaneous preservation of the specific volume of the treated web.

Title: Long-path laser interferometer
IPC: G01B9/02
Filed: 1988-10-21
Granted: 1990-01-11
Abstract: The invention relates to a laser interferometer in which in addition to the otherwise customary interferometer design the measuring distance is subdivided by means of a plurality of shifting units which can be shifted along the measuring line into a plurality of separate interferometer measuring sections which adjoin one another directly in the manner of a chain. Like the base unit of an interferometer, the shifting units are likewise equipped with optical components of an interferometer which are arranged in the beam path of the measuring distance. Each shifting unit is supplied with primary light, and includes a polarisation beam splitter with a reference reflector, as well as a measuring reflector and a measuring detector for the associated secondary light. The function of the measuring reflector of any shifting unit can also be undertaken by the respectively associated reference reflector. By virtue of the subdivision of the measuring distance into a plurality of interferometer measuring sections, the measuring distance can be extended to a multiple of the coherence length without the measurement accuracy and the clarity of the interference signals suffering thereby. All the shifting units are preferably shifted at the same time and in the same direction, but at a different speed, which is linearly graded, with the result that the relative shift within all the measuring sections is at least approximately of the same size. A high rate of travel of the terminal measuring reflector is thereby permitted. Various other measures, in particular for reducing ... Original abstract incomplete.

Granted: 1993-03-04
Abstract: In order to produce a contact between a condenser electrode (13) located in a trench (11) and an MOS-transistor source/drain region located outside the trench, the invention calls for the trench (11) to be produced by making a shallow etch in the substrate (1), trued with respect to the field oxide region which insulates the MOS transistor. After forming an Si3N4 spacer (10) on the substrate wall (8) exposed by the silicon-selective etching operation, the exposed part of the field oxide region (2) is first removed using a mask, and then the trench (11) completed by means of a further etching operation. The contact is produced by formation of an SiO2 film (12) on the surface of the trench (11), removal of the Si3N4 spacer (10) and formation of the condenser electrode (13) on the substrate wall (8) exposed by removal of the Si3N4 spacer (10).
