Patent DE-3705396-A1 (DE)
Title: Method and installation for the production of angled or u-shaped handle elements
Inventor: BUERGER FRIEDHELM
IPC: B23P23/06
Filed: 1987-02-20
Abstract: Method for the production of angled or U-shaped handle elements, sections being cut from a sectional bar and processed further to give the handle elements. Straight sections are cut from the sectional bar, which has a round, oval or polygonal cross-section and is drawn off from a coil. These straight sections of the sectional bar are bent into pre-finished parts in the form of angled or U-shaped handle elements. These pre-finished parts are stamped to give a pre-determined cross-sectional shape and are then deburred and, in a final shaping operation, shaped to give the finished handle elements by cold deformation and/or cutting, at least at their connection end. An installation for carrying out the method is also disclosed. <IMAGE>

Title: Hand-held power tool
Inventor: BLEICHER MANFRED
IPC: B23B45/16
Filed: 1987-09-17
Abstract: There is proposed a hand-held power tool, e.g. a hammer drill, having a motor-driven air-cushion percussion mechanism in which the percussion mechanism is driven via a gearing with coupling. The coupling is constructed as a wrap-spring coupling. It has a drive hub driven by the drive motor, an axially adjacent driven hub with approximately the same outside diameter, and a wrap spring which is held on both hubs, wrapped around them, in a clamping manner. The wrap-spring coupling is constructed as a clutch coupling. At the winding part seated on the drive hub, the wrap spring has a transversely projecting switching finger, on which engages a switching device, automatically actuable by hand and/or by the machine, which stops said switching finger for the purpose of uncoupling and frees it for the purpose of coupling. The wrap spring coupling makes it possible to switch the percussion mechanism on and off path-dependently with a minimum travel requirement and without special axial pressure force. <IMAGE>
Patent DE-3733889-A1 (DE)
Title: Series regulator
Inventor: LOESEL WALTER
IPC: G05F1/569
Filed: 1987-10-07
Abstract: The series regulator described contains a first controllable resistor (TO1) and a measuring resistor (RO1) connected downstream in a first series branch, and a second controllable resistor (TO2) for limiting the current, of which the control electrode is led via a bias resistor (RO2) to the connection point of the measuring resistor (RO1) of the first controllable resistor (TO1). In order, inter alia, to switch off automatically a dowmstream dc voltage converter in the case of voltage dips or overloads, provision is made to insert a switchable current source (SQ) between the control electrode of the second controllable resistor (TO2) and the second series branch of the series regulator. This current source (SQ) alters its switching state if the output voltage (VA) of the series regulator falls below a threshold. In the altered switching state, the current flow (I) through the bias resistor (RO2) adjusts itself so that the current is limited at small output currents (IA). <IMAGE>

Patent DE-3808680-A1 (DE)
Title: Turning device for appliances for baking with fat
Inventor: MACHNER HANS-DETLEF
IPC: A21B5/08
Filed: 1988-03-11
Abstract: Known turning devices for items baked in fat must solve the problem of reliably turning over the pieces of dough as they are turned from one side to the other. Known turning devices achieve this by setting the supporting grid at an acute angle and arranging a tripping edge. This results, however, in a reduction in the space which can be occupied on the supporting grid, nor does it ensure that turning over occurs in every case. According to the invention, the supporting grids of the turning baskets are arranged at right angles and the pivoting device is designed in such a way that the pivot region covers a pivot region extending beyond the two operating positions. This means that turning over can be reliably achieved, and that subsequent returning of the turning baskets to the operating position is possible. Dispensing with the arrangement of the supporting grids at an acute angle and with a tripping edge means that the space available on the supporting grid can be used to support the pieces of dough.

Patent DE-3813899-A1 (DE)
Title: Conveying device for solids into or out of process spaces at different pressures
Inventor: ECKEN JOSEPH DIPL ING
IPC: B65G53/46
Filed: 1988-04-25
Abstract: The conveying device serves for the continuous removal or feeding-in of non-pumpable granular or lumpy substances between spaces at different pressures, e.g. vacuum plants, pressurised reactors or the like. For this purpose, the material, which is located in a preferably funnel-shaped collecting space, is pushed, by means of an oscillating piston, into a chamber having a deformable outer cover. The material filling is conveyed into a higher or lower pressure level while the receiving housing part is moved back and the piston is in the extreme position with sealing taking place by the outer cover being acted upon by pressure from the outside. The emptying aid is the push-out piston. The transfer can take place in plastic sacks or containers, possibly also in an inert gas atmosphere, in the event of usage as a removing device. <IMAGE>

Title: Mineral compositions for producing shaped parts for pressure chambers
Inventor: VOLLSTAEDT HEINER PROF
IPC: C04B35/19
Filed: 1988-06-20
Abstract: The materials hitherto used for lining the reaction space of high-pressure chambers, in particular the belt types, do not allow the deformability of the internal parts, the pressure transmission properties and the flow behaviour and also the support and sealing action to be optimised. In place of the materials hitherto known for lining high-pressure chambers, a material is provided which simultaneously and optimally fulfils sealing, support and force transmission functions and also reliably ensures insulation against electric current. The object is achieved by mineral compositions comprising the mineral paragonite or mixtures of paragonite with one or more materials such as, for example, talc and/or muscovite, with the mass ratio of paragonite and additives preferably being from 5:1 to 2:1. It is preferably used for the synthesis of super-hard materials, in particular for the production of synthetic diamond.

Title: Method and device for the determination of the compactness of cohesive or non-cohesive soils
Inventor: YETGIN SUEKRUE DIPL ING
IPC: G01N9/02
Filed: 1988-08-16
Abstract: The invention relates to a method for the determination of the compactness of cohesive or non-cohesive soils, in which the soil sample is introduced into a container and is clamped down with a tamping plate, as well as a device for carrying out this method, consisting of a container which can be extended by at least one attachable extension piece, and of a tamping plate. It is the object of the invention to provide with simple means a device with which the compactness may be determined in a relatively short time, with a smaller expenditure of energy and with higher exactness, the possibilities for automisation being also considerably improved. The device according to the invention is characterised in that the container can be closed by a lid, in that the tamping plate is placed in the interior of the closed container and has an external diameter which is only slightly smaller than the internal diameter of the container, and in that the container is placed in a guide or a guide cage for the free fall of the container. The method is carried out in such a way that, after introducing the soil sample into the container, the tamping plate is inserted into the container and then the container is closed and that the container is then allow to fall in free fall once or a plurality of times onto a solid body, the container being guided vertically.
Patent DE-3830747-A1 (DE)
Inventor: FREUND ECKHARD PROF DR ING
IPC: G05D1/02
Filed: 1988-09-09
Abstract: A new process and device are useful for driving a vehicle in a precisely determined manner on an ideal course as steadily as possible under the variable dynamic driving situation. A compensation and control arrangement is provided to enable a vehicle to follow a predetermined ideal course with a predetermined speed profile automatically and autonomously. The control arrangement derives the regulating values for the angle of steering and the driving or braking forces of the vehicle from the difference between the actual and preset values on the basis of preselected parameters for adjusting the dynamics of the controlled vehicle. A compensation arrangement simulates dynamic coupling with other parameters of motion and compensates these interferences. The process and device are suitable for guiding a vehicle automatically along a preset course.

Title: Shutter-opening means for window or door shutters
Inventor: FUERNDRAT GERHARD
IPC: E05F5/12
Filed: 1988-11-25
Abstract: A shutter-opening means for window or door shutters (12, 13) is actuated by means of a hand crank (1) or the like. The rotary movement is transmitted onto a shaft (3) on which there is arranged a worm (4, 5) which engages into a worm wheel (10, 11). The worm wheel (10, 11) is connected to the shutter (12, 13) directly or indirectly via a linkage or the like, with the result that, upon actuation of the hand crank (1), the shutter (12, 13) can be opened or closed. The worm (4, 5) is mounted on the shaft (3) such that it can be axially displaced, counter to spring force (6, 7, 8, 9; 8', 9'), but is fixed in terms of rotation. Consequently, upon reaching a stop position of the shutter (12, 13), the crank (1) can be further rotated, the worm (5) being displaced along the shaft (3) counter to the spring force (8') and transmitting the spring force onto the shutter (13). <IMAGE>
Patent DE-3902368-A1 (DE)
Title: Superfast charging device for gas-tight Ni-Cd accumulators (rechargeable batteries), known by the name of SS-20 (20 min. charging time
Inventor: BECH JAROSLAV
IPC: H02J7/00
Filed: 1989-01-27
Abstract: The subject matter of the invention is a charging device which allows recharging of gas-tight Ni-Cd accumulators in extremely short time, so that "top-up" charging, trickle charging or recharging of a battery which is not yet discharged is no longer sensible. All these mentioned charging types which have been applied hitherto considerably reduce the lifetime of the battery. With the SS-20 charging device, only a battery which is actually discharged is ever charged, so that the "overcharging phase" which is generally most detrimental to the lifetime and the functional capability of the battery is avoided. Through the possibility of charging with relatively high charging current, a higher charging efficiency and therefore a higher drawable capacity are achieved.
Patent DE-3906067-A1 (DE)
Title: Method for positioning a radar antenna
Inventor: GRUBER HANS-ERICH
IPC: H01Q3/04
Filed: 1989-02-27
Abstract: After entering a positioning command, a control contact (K0) which defines the positioning point is actuated by means of a stud (2) located on the antenna shaft (1), which control contact (K0) alternately switches a three-phase asynchronous motor (which drives the antenna in a delta circuit) between running in the normal rotation direction and running in the opposite rotation direction like an oscillating drive until, as a result of the friction, the antenna is oscillating only over an angle corresponding to the width of the switching stud or stops in this region, the antenna drive being interrupted during the control contact actuation. If a magnetic break is caused to operate during the actuation of the contact (K0), then the number of oscillation processes is reduced and the antenna comes to rest earlier. This number can be still further reduced if the initial switching into the opposite rotation direction is carried out earlier by means of an additional control contact (K1). The method according to the invention for positioning can be used in the case of surveillance radar antennas fitted to vehicles. <IMAGE>
Patent DE-3910531-A1 (DE)
Title: Measuring (gauging) station (point) set up inside a production line
Inventor: ZICK MANFRED DIPL ING
IPC: G01B21/00
Filed: 1989-04-01
Abstract: The invention relates to a measuring station set up within a production line, which by virtue of its programmability automatically measures the workpieces which are being machined (shaped by cutting) in the production line. It is to be possible in this case to preserve a measurement accuracy of at least 10<-4>, or, better still, of 10<-5>, for which reason it is generally necessary for the measuring space to be air conditioned. In order to be able to avoid measuring in an air conditioned environment and yet to preserve the high measurement accuracy, it is proposed according to the invention to carry out the manipulation cycle during measurement with the aid of a commercially available industrial robot and to undertake the actual measurement itself by means of gauges adapted to the workpiece. The gauges are designed for a limited measurement range and operate with the required measurement accuracy. Each gauge can be mounted in a quickly exchangeable fashion on the external end of the working arm of the industrial robot. In order not to impair the measurement accuracy of the gauges by temperature fluctuations in the environment, after being used the gauges are immediately deposited again in an air conditioned cabinet whose flaps or doors can be operated automatically in a manner integrated in the control of the industrial robot. During the short measuring time, the accuracy of a gauge is not impaired by temperature disturbances. As a result, the investment cost of such a measuring station can be very substantially reduced.
