Patent DE-2854791-A1 (DE)
Title: Textile cleaning process - uses three main phases in one chamber without intermediate drying
Inventor: BIESINGER ERWIN
IPC: D06F43/00
Filed: 1978-12-19
Abstract: In the cleaning process for textile materials using a chemical solvent and water, the material is treated in the same vessel in 3 main phases without any intermediate drying, using a bath for each. The pre-wash phase uses the chemical solvent applied to the material without water. The following wash phase uses water fed to the material. The final phase uses further chemical solvent to aid subsequent drying. The chemical solvent is fed in limited doses in an undissolved, unemulsified and non-alkali water-soluble soap, to give a non-ionic or anionic surfactant concn. The water bath in the washing phase is used again for a subsequent cleaning cycle, such as a pre-wash for coloureds. The process gives an effective cleaning action to textile materials, without any damage to the environment.

Title: Electrically heated dental casting mould - has PTC element and transformer with tappings and control for LV at low temp. stepped up at full load
Inventor: EIERMANN KURT DIPL PHYS DR
IPC: A61C13/20
Filed: 1978-12-27
Abstract: An electrically heated casting mould for dental purposes, consists of a melting crucible with a heating coil made from a material with a positive resistance temp. coefft. The heating current is supplied via control circuit. The heating element is protected in that the voltage is kept relatively low when heating over the lower temp. range. The voltage is increased for the high temp. ranges. This prevents any precipitation of alloys onto the heating element. It also eliminates transient currents and mechanical stresses. The supply is via a transformer with two voltage tappings. There is a relay with change-over contacts and an electronic output regulator which controls the switching programme of the current to the heating element.

Title: Self-clinging textile band for garment fastenings - has zones of hooking threads and fleecy loops arranged symmetrically
IPC: A44B18/00
Filed: 1979-02-21
Abstract: Thermoplastic threads, the ends of which are formed into hook or mushroom shapes, are bound in with the threads of a clinging textile material, to form the cling surface. Close to the edge of the cling surface, there is at least one fleecy surface with loops which are suitable for hooking together with the deformed ends of the thermoplastic threads. The loops are arranged within an area which is symmetrical with the cling surface relative to an imaginary line between the two areas. The two areas are arranged on a band of which the imaginary straight line forms the longitudinal centre line. With this band the accidental adhesion of the cling surface to knitted and woven articles, when they are brought together, as in a washing machine, is prevented with certainty, the band being simply folded double.

Title: Strip prodn. of contact fingers with fold-over connectors - set to standard contact spacing by deformation of temporary joining strip
Inventor: ECKERT GEROLD
IPC: H01C1/14
Filed: 1979-04-27
Abstract: The mfg. method forms contact fingers at a closer spacing on the temporary joining strip than before. The contact strips are of the type which fold over the circuit end to be connected, e.g. by passing through slits in a circuit board and folding over the printed conductor. The contacts are punched out of a continuous strip of metal to form T-headed fingers of two lengths (3, 4). The length of the T-head (8) in the open position is slightly more than the standard contact spacing. The residual metl strip (1), acting as a temporary joining strip for the contacts, is then deformed (9) by a press tool to the extend required to correct the spacing between contacts to the standard dimension. They can then be fitted to the appts. to be connected and the strip (1) cut off.

Title: DC alarm signalling system - has two parallel lines connecting series of units, with terminal impedance and memory to record impedance at various times
Inventor: SCHREYER KARLHEINZ
IPC: G08B25/04
Filed: 1979-08-31
Abstract: The d.c. alarm signalling system is based on a central transmission unit (Z) connected to a two-wire line (L) to various alarm units (M1,M2) in a series connection line.

Title: Ultrasonic fluid level indicator - has sensor rod or tube of material distinctly distinguishing between ultrasound transfer media
Inventor: BUSCHMANN HEINZ
IPC: G01F23/296
Filed: 1980-01-22
Abstract: The fluid level indicator providing a continuous level display uses ultrasound so as to achieve a significant cost reduction compared to conventional devices. An ultrasound conductor with an ultrasonic source on one end and an ultrasonic receiver on the other is immersed in the fluid. Measurement elements acquire the amplitude or power of the ultrasonic oscillations transferred from the source (12) to the receiver (13) and feed them to indicator elements (22). A rod or tube sensor (1) may be used, in which case it is of a material giving a distinct difference between the transfer of ultrasound in air and the liquid. Alternative forms of sensor are metal rods, pref. thick-walled metal tubes, e.g. of steel, or rods of non-metallic material.

Title: Methanol and crude oil transportation in a pipeline - as alternate slugs of methanol-oil emulsion and methanol, opt. contg. powdered coal
Inventor: BAYER ALFRED DIPL ING
IPC: F17D1/08
Filed: 1980-10-27
Abstract: In a process for transport of methanol and crude oil through a pipeline, slugs of methanol alternate with slugs of an emulsion of small concns. (less than 10%) of methanol in crude oil. Coal may also be transported, by adding it, finely ground, to the slugs of methanol. Process is used esp. for paraffinic crudes, of viscosity 10-250 mPas at transport temp., and for prodn. ratios oil:methanol of 85:15 to 40:60. The method of transporting coal is useful in regions where other transport systems are difficult to develop, e.g. the arctic. The viscosity of the oil phase is reduced, e.g. by 10-25% by 2.2-3.5 vol.% methanol, so that less pumping energy is needed or flow rates can be increased.

Title: Electronic touch control switch - uses operational amplifier with resistive feed back comparing sensor electrode signal with reference signal
Inventor: MAIERFRANKENFELD WENZEL
IPC: H03K17/96
Filed: 1980-11-07
Abstract: The switch uses the variation in resistance or capacitance when a sensor electrode (4) is contacted by a finger. The sensor electrode (4) is coupled to the inverting input (E1) of an operational amplifier (1), its non-inverting input (E2) coupled to a reference source (2), e.g. a rectangular or sinusoidal pulse generator. A resistive feedback loop is coupled to the inverting input (E1) of the operational amplifier (1), its output fed to an evaluation stage (5) responsive to the amplitude variations in the output signals to provide the switching signals. Alternatively the evaluation stage (5) responds to the phase shift between the amplifier input and output signals. The switch is not effected by parasitic factors.
