Title: Lining process for underground pipeline - uses plastics extrusion head pulled through pipe by winch for continuous, even coating of pipe interior
Inventor: BILLINGER GERHARD
IPC: F16L55/1645
Filed: 1992-09-12
Abstract: The extrusion head (2) is selected to fit the pipeline with a preset spacing. It is pulled through the pipe extruding a continuous film of plastics on to the wall of the pipe via integral extruders and with the power and material supplies via a trailing supply hose (4). The supply hose carries a pneumatic duct for granular plastics, a return feed for excess granules, cooling ducts and power lines. The extrusion head is pulled through the pipe by a winch (3) at a controlled rate. The extrusion rate is controlled w.r.t. the required lining thickness and the pulling speed. Spacers hold the extrusion head centrally inside the pipe. USE/ADVANTAGE - Esp. for drainage and sewage pipelines. Seamless lining, less risk of cracks, simple to apply.

Title: Method and appts. for welding bolts with an ignition tip to workpieces - with prior measurement of the tip length and adjustment of the bolt feed rate, achieves constant joint quality
Inventor: GAUGER WOLFGANG DIPL ING
IPC: B23K9/20
Filed: 1992-10-29
Abstract: The method and appts. for welding bolts and similar items with an ignition tip to workpieces with the use of a capacitor discharge to produce a welding current - which evaporates the ignition tip and creates an arc - are characterised by: (a) the length of the ignition point is measured before the start of the welding process by means of a measuring device (10); and (b) the resultant electrical signal is fed into a processor (9) which computers the required constant feed rate of the bolt and issues it as an electrical signal to a feed rate adjusting device (8). Bolts with a length of the ignition tip outside a given tolerance field are automatically withdrawn from the process. Measurement of the length of the ignition tip and supply of the bolts to the welding head take place in the same sequence. USE/ADVANTAGE - For attachment of bolts and similar items to workpieces. Constant joint quality is achieved in spite of variations in the length of the ignition tip.
Patent DE-4236779-A1 (DE)
Title: Optical data disc reader - balances difference between output of pair of photodetectors sensing laser beam spot reflected from diskette
IPC: G11B7/005
Filed: 1992-10-30
Abstract: The difference between the output signals of the photodetectors (4) is determined, pref. by a differential amplifier (10). The intensity of one of the output signals is changed, pref. by a variable-gain amplifier (11) so that the difference is reduced to zero. The output signal of one photodetector element (PD2) is extended to the non-inverting input terminal of the differential amplifier via the variable gain amplifier. The output of the other photodetector element (PD1) is extended to the inverting input terminal. The differential amplifier supplies an absolute time decoder (8) and has a feedback loop (15) to the variable gain amplifier. USE/ADVANTAGE - Reading diskette with information stored in wobble groove. Reads information in absolute time even if reflected beam spot is deflected.

Title: Retention of over-spray in spray painting - has paint caught on continuously moving filtration surface which passes through washer and is returned
Inventor: SCHLUMPF GEORG
IPC: B05B14/20
Filed: 1993-01-09
Abstract: Overspray in spray painting is caught by a continuously circulating filtration surface which runs through a washer (6) where the paint particles are washed out again. The surface can be an endless band (4) running over rollers (5), a rotating vertical disc or a horizontal roller. It can consist of nonwoven polyester bonded to a woven backing. A spray booth (1) has an air extract duct (2) covered by an exit grid (3) along the back wall. A continuous moving filter band (4) covers the back wall and retains the overspray from the paint spray gun (10). The band (4) moves over rollers (5) into a wash plant (6) where the paint is removed and it then passes into a drying zone (11) with squeeze rollers before returning. The wash fluid is recycled by a pump (13). When a certain paint concn. is reached, the wash fluid is drawn off by a valve (14) to a separate filtration plant. In an alternative embodiment the filtration surface is mounted on a vertical disc with the upper half retaining overspray and the lower half passing through the washer. USE/ADVANTAGE - Excess paint can be reclaimed with less environmental pollution.

Title: Process and apparatus for forming a clot (blank) from a formable material, such as clay
Inventor: GMEINER MARKUS DIPL ING
IPC: B30B11/22
Filed: 1993-10-05
Abstract: A process for forming a clot from a formable material, such as clay, in the case of which the cross-sectional configuration of the clot is determined by the discharge cross-section of a die through which the strand of material is pressed out, is distinguished in that said discharge cross-section is changed during the pressing-out operation, for example by symmetrical narrowing and re-widening of said cross-section in the direction of the centre of the strand and away from the same. This makes it possible to produce clots from the material without any waste.

Patent DE-4341721-A1 (DE)
Inventor: XIE JIAN DR ING
IPC: H01F38/08
Filed: 1993-12-03
Abstract: The invention relates to a transformer having a laminated core in the form of a frame, into whose central free space windings project which are grouped as n pairs, each composed of an inner high-voltage winding and an outer low-voltage winding located above it, around two of the opposite limbs of the laminated core, in particular for parallel operation with a plurality of supplying four-quadrant controllers. When a 16 2/3 Hz AC voltage is produced from a DC voltage by means of pulsed four-quadrant controllers, interfering current harmonics occur. In order to reduce the harmonics in a simple manner - that is to say without increasing the transformer costs, the transformer volume or the transformer weight - it is proposed according to the invention that one or more cruciform intermediate yokes (8) be inserted into the central free space (7) in the laminated core (6), which yokes divide the free space (7) into windows (9) for the individual winding pairs (1/3) in which these are inserted, and that the high-voltage windings (3) be connected in series. <IMAGE>

Title: Hearing aid adjusting method
Inventor: GRAHN JUERGEN
IPC: H04R25/00
Filed: 1994-01-07
Abstract: The hearing aid adaptation method provides the programming device (PG) via one or more signal generators or noise generators for the low frequency range. The low frequency signals can be generated with a definite frequency and a definite level. These signals can be fed via the audio input to the hearing aid. The programmer (PG) sends different signals to the hearing aid (HG) according to a predetermined plan. The tester acknowledges whether he has heard each signal. This process is repeated until a statistically sufficient statement on the required properties of the hearing aid (HG) is present. The hearing aid (HG) is adjusted according to the derived handicap and the adjustment is tested with the above method.
