The distance actually travelled by the casting piston is measured, whereupon the flow of pressure medium in the injecting part is controlled at least during the first and/or second phase of the current casting process in such a way that the speed of the casting piston has the function value corresponding to the actual value of the travel of the casting piston.
Patent DE-3145080-A1 (DE)
Title: Freely programmable open-loop, closed-loop control
Inventor: SCHWARZ SIEGFRIED
IPC: G06F15/78
Filed: 1981-11-13
Abstract: To create inexpensive freely programmable open-loop and closed-loop control systems, the standard programs for open-loop control, closed-loop control, the beginning and the end of all possible program types, the command interpreter for the free programming of assembler commands and the test program for indicating the results are stored in the read-only memory of a single-chip microprocessor. The user program is stored externally in an EEPROM read-only memory. This is used for calling up assembler commands and the standard commands prepared in the single-chip microprocessor by means of the so-called call command. For this to be possible, the program types are initialised in the single-chip microprocessor after which each program jumps to a defined starting point in the user program. After the user program has been run, each program, for terminating the user program, branches back to a defined end point in the single-chip microprocessor where the programs are terminated according to plan. To indicate the results of the commands, a marker is set which appends to each standard command a test program which automatically indicates the marked results when the selection criteria additionally entered have been met.

Abstract: The development of the doorcase according to the patent application of 14 March 1981, having the application number P 3110155.0-25, is intended to improve, in particular, the security of the doorcase against break-in by individual latching and/or locking elements (striking-plate replacement), according to Figures (1 to 3), which can be screwed fixedly, and such that they are secured with respect to impact, to the mounting units arranged behind the inner legs (11 + 12) of the corner claddings (1 + 2), Figures (6 + 7). For this purpose, the door-hinge retaining means in the abovementioned patent application are developed, corresponding to Figures (6 + 7), as mounting units and are provided with threaded bores (70 to 77) into which the screws (106a + 108a) engage. The mounting units are further provided with grooves (68 + 69) into which the angular fastening elements (13) of the visible lining (4) latch. Owing to the arrangement of a threaded bore (78) in the axis centre point of the mounting unit, the alignment element may also be set into the starting position which is most favourable in each case. The latching and/or locking elements, Figures (1 to 3), may also be fitted subsequently, one by one, on doorcases which have already been mounted, as a result of which the storage of two types of doorcases "DIN left-hand doorcase" and "DIN right-hand doorcase" is dispensed with. <IMAGE>

IPC: F16C19/56
Filed: 1983-02-09
Abstract: The invention relates to a method for adjusting angular contact rolling bearings to a predetermined preload value, in which the initial length of a measuring section of a component deformed elastically upon preloading is measured in the non-preloaded condition, as is the change in its length during preloading, by means of radiation passing through the measuring section and reflected at its end, and when the actual change in length which occurs during preloading coincides with the desired change in length determined in a preliminary trial, the adjustment process is ended. A component for an angular contact rolling bearing adjustable to a predetermined preload comprises a measuring section deformed elastically upon preloading and a reflection surface arranged at one end of the latter and extending essentially at right angles to its length.
Patent DE-3304902-A1 (DE)
Title: Device for determining the mass flow rate of a flowing medium
Inventor: GRUENWALD WERNER DIPL PHYS DR
IPC: F02D41/32
Filed: 1983-02-12
Abstract: A device is proposed which is used for determining the mass flow rate of a flowing medium, especially the air mass flow rate which is sucked in by an internal-combustion engine. The device comprises at least two temperature-dependent measuring resistors (10, 11), which are subjected to the flowing medium, in in each case one separate bridge circuit, which are heated to different, constantly regulated temperatures (T1, T2). The measuring resistors (10, 11) are constructed as film resistors, in the same way as the other bridge resistors, and are arranged opposite, in each case on a different side of a substrate. In each case one signal which is dependent on the currents (i1, i2) flowing through the bridges is supplied to a signal processing unit (22) whose output variable represents a measure, which is independent of the temperature (Tu) of the flowing medium, for the mass flow rate (qm) of the flowing medium. <IMAGE>
Patent DE-3312988-A1 (DE)
Title: Lamellar blind
Inventor: GRAMSE GEB KRAUSE
IPC: E06B9/386
Filed: 1983-04-12
Abstract: The invention takes as its departure point lamellar blinds having lamellae which can pivot about a vertical axis. The main endeavour of the invention is that the blind should not only alter the influence of light and sun, but, in addition, should also be able to contribute to an air-conditioning of the associated room. This is achieved by one or more air ducts which run parallel to the lamellae and have an air-inflow opening at the bottom and an outflow opening at the top. Furthermore, however, the air ducts are translucent, at least in some areas, such that the air located in the duct can heat up.
Patent DE-3318685-A1 (DE)
Title: Mechanical gearing, infinitely variable from plus to minus
Inventor: WUERTH GUSTAV DIPL KFM DR
IPC: F16H3/76
Filed: 1983-05-21
Abstract: By virtue of the roller chain which passes in a circle over the roller gearwheels and the circle diameter of which can be varied by displacement downwards and upwards by means of a displacement device, rotation of the input shaft part also involves a change in the speed of rotation of the roller gearwheels. If, in the process, the step-up ratio of the roller gearwheels relative to the circle diameter of the roller chain has reached the reduction ratio of the output gearing part, the input shaft part A rotates about the output shaft part B without a difference, i.e. the output part B remains stationary. If the step-up ratio becomes larger than the reduction ratio of part B, which remains constant at all times, part B is set in rotation in accordance with the change in the step-up ratio, beginning with the minimum difference. If, on the other hand, the step-up ratio of part A falls below the reduction ratio of part B, this part B is set in rotation in the opposite direction, likewise in accordance with the change in the step-up ratio. Thus, when part A rotates, the output part B can be set in rotation in an infinitely variable manner from standstill, in both directions.

Patent DE-3406744-A1 (DE)
Title: Method for the selective, precise surface enlargement, drying and shaping of smooth materials such as pieces of leather, hides and the like
Inventor: NINK HERMANN
IPC: C14B1/26
Filed: 1984-02-24
Abstract: The mode of operation of the method is that a piece of leather (17) is introduced between two films (1) and (2). The balls are supported, relative to the leather by the forces (A) and (A') and the pressures (p) and (p') are generated in them by compression. This produces, on the leather, the contact pressures (B) and (B'), the stretching forces (C) and (C'), the shaping forces (D) and the shearing forces (F) and (F'), which permanently enlarge the leather. If the leather is to be dried during the stretching operation, the medium (9) is warmed. If the stretching is to be selective (differentiated), the medium can, for example, be repeatedly pressed into film (1) and, in addition, a positive mould (20) or a negative mould (19) can act against the film (2) with the force (D). In order that the increase in the medium (9) in the film (1) should not entail any increase in the stretching forces (C) and (C'), so as to avoid any undesirably forceful stretching or any tearing of the pieces of leather, the forces (E) and (E') must be applied. <IMAGE>
