Title: Elbow forming composite die - has inlet guide, swaging, and tubular bending sections, and is for shaping of straight pipe lengths
Inventor: KAHLOW KURT J
IPC: B21D7/08
Filed: 1979-04-04
Abstract: The composite die for forming an elbow from a straight tube pushed through. It comprises a tubular inlet guide section, and a swaging section in the form of a truncated cone connected and opening at its large end to one end of the inlet guide section. The swaging section is constructed and arranged so that the tube while pushed through it is subjected to circumferential swaging forces varying from a maximum at one location on its circumference to a minimum value at another opposed location on its circumference. The tube is subject to an offset of die forces producing a force movement, to cause bending of the tube about the location subjected to the minimum swaging forces and thickening of the tube wall, partial forming of the elbow and reduction in tube diameter.

Title: Hydraulic transport pipe of polyamide - mfr. with differential wall thickness in eccentric rotational casting moulds
Inventor: GEISLER NORBERT
IPC: F16L57/00
Filed: 1979-04-10
Abstract: Pipes or open gutters for the hydraulic transport of coal, or or other solids in mines and quarries are made of polyamide by a centrifugal casting technique. The wall thickness is thereby made much greater in the lower sector where is abrasion is concentrated. Such a pipe is produced by mounting the rotational casting mould concentrically and adding external balance weights. If a thicker wall thickness is provided at two diametrally opposite sectors, the life of a tube can be double by a 180 degrees turn. Alternatively it can be split equatorially to produce two open gutters. Such a pipe is produced by a mould with an oval cross-section of its cavity.

Title: Monitoring degree of annealing of wire - where constant tensile stress produces permanent deformation used in electron pulse counting circuit to adjust annealing temp.
Inventor: KRIEGER JOERG
IPC: G01B7/04
Filed: 1979-12-12
Abstract: An idling inlet roller and an idling outlet roller are mounted coaxially on a single shaft; and each roller is fitted with a contactless digital pulse transmitter. The wire is pulled by a constant force round inlet roller and then round one or more rollers before travelling round outlet roller. The wire undergoes a permanent deformation by this process. Each pulse transmitter is connected via an amplifier to a counter; and the difference in the number of pulses counted represents the increase in length (dL) of the wire caused by the rollers. After 100,000 pulses, the result is fed into a memory store and fed to a visual display unit and to a controller adjusting the voltage in the electric resistance annealing of the wire. Used in prodn. of annealed wire with constant mechanical properties.

Title: Appts. recovering solvent from dry cleaner exhaust - has refrigerator at top and feeds vapours at bottom
Inventor: KRUGMANN HANS-GUENTHER
IPC: D06F43/08
Filed: 1980-04-02
Abstract: Appts. for recovering solvents from the air extracted from dry-cleaning machines, metal cleaning machines, etc. blows the air through a ring circuit back to the machine. The circuit includes a separate unit with a refrigerator-cooled labyrinth which condenses the solvent and drops it together with condensed water into a collector container from which the two media are sepd. by simple standard method. The refrigerator heat exchanger is located at the top of the labyrinth and the extracted air flows through labyrinth and exchanger from the bottom upwards. Since the coldest section of the sepn. unit is at the top, most water is condensed in the relatively warmer bottom section before the vapour condenses at the top. This reduces the risk of blocking by ice and permits use of smaller exchangers and blowers.

Patent DE-3028708-A1 (DE)
Inventor: MILLER WALTER DR
IPC: G05B19/4093
Filed: 1980-07-29
Abstract: A programmable, numerically path controlled processing device of the type which includes a controller, a display unit coupled to the controller, and a keyboard input unit, also coupled to the controller, is programmed selectively to display two alternate sets of dialog texts to structure the programming of the control unit. One set of dialog texts is relatively lengthy and complex and is suitable for general purpose path programming. The second set of dialog texts, on the other hand, is relatively simple and short and contains only dialog texts suitable for programming the processing device in the axially parallel, interval programming mode. The interval programming mode is simpler and more limited than the general purpose path programming mode, and therefore, by calling up the second set rather than the first set of dialog texts, an operator can program the processing device in the interval programming mode in a shorter period of time and in a more direct manner.

Title: Chipboard or fibreboard press had endless bands - supported by transverse rollers subdivided into short lengths mounted on wide plates
Inventor: PFEIFFER HEINRICH
IPC: B30B5/06
Filed: 1980-11-14
Abstract: The parent patent describes a continuously operating press for producing chipboard, fibreboard, plywood panels and/or for coating panels and the like. Endless flexible upper and lower belts passing around rollers form the channel through which the material passes and is pressed in the pressing zone a series of transverse rollers provides the pressing force, being fixed to the stationary table for the lower endless belt and mounted beneath the movable pressing frame for the upper endless belt. Each of the these transverse rollers is sub-divided into a series of short, separate rollers mounted on several rods extending transversely across the press, thus the roller assembly comprised a number of removable plates, also containing heating and cooling pipes or other devices, which transfered the pressing pressure in a first level (roller level) to the rods or tubes acting as their shafts, from which the pressure was in turn transmitted as a lower unit pressure over a greater area onto pressure plates at a second level. In the Patent of addition, the removable plate (that for the lower part of the press is shown) is composed of a single pressure plate, constituting the second level referred to above, and extending across the entire width of the press and of several T-shaped web plates carrying the roller shafts, and of a single mounting plate with an insulating board between it and the pressure plate. Process is used for the continuous production of chipboard, fibreboard, panels and the like, where considerable pressure has to be applied across the width of the endless belt.
Patent DE-3044027-A1 (DE)
Inventor: MUELLER ROLF DR ING
IPC: H02P7/288
Filed: 1980-11-22
Abstract: A rotation speed regulator for an electric motor (10) has a tachogenerator (38) which emits short pulses (18). These pulses are fed to a discharge transistor (19) which discharges a first capacitor (25) whenever such pulses (18) arrive, which first capacitor (25) is subsequently charged again via a charging element (27). The voltage on the first capacitor (25) is fed to a threshold-value element (24) which triggers only when the voltage on the first capacitor (25) exceeds a specific threshold value and which, when such value is exceeded, acts such that a second capacitor (33), which is used as an integrating capacitor, is fed with corresponding charging current pulses (30). The higher the motor rotation speed, the shorter these current charging pulses (30) become, and, in addition, the lower the voltage on the second capacitor (33) to which a relatively high-value resistor is allocated as the discharging element (34). This voltage on the second capacitor (33) is fed to a current regulator as a reference variable, to which current regulator (35), furthermore, an actual current value (36) is fed from a measuring resistor (12) in the feed line of the motor (10), so that a high motor current is supplied at low rotation speeds, which current reduces more and more as the motor rotation speed approaches the desired value. <IMAGE>
