Title: Winding bobbin dampener - has hydraulic piston unit to dampen oscillations on bobbin path towards the contact drive roller
Inventor: POHN ROMEO
IPC: B65H54/52
Filed: 1991-07-01
Abstract: To dampen oscillations at a winder, where the bobbin is rotated by contact with a drive roller, the bobbin oscillations are dampened on the bobbin path towards the drive roller. Pref. a hydraulic dampening action is used. The dampener (5) has a cylinder (51) with a piston (52) on a piston rod (53) to transmit the movement of the bobbin holder (2) to the piston (52). The piston (52) has openings (56) to allow the medium in the cylinder (51) to flow through. The openings (56) are closed on a movement of the bobbin (4) towards the drive roller (2), and are opened on a reverse direction. The piston openings (56) are covered by a membrane (57), pressed against the piston (52) by a spring. The piston (52) has overflow channels for medium overflow in the dampening direction of the piston (52). One end of the dampener (5) has a claw, for a snap fit to a mounting bolt, using a plastics claw with a spring to reinforce the clamping action on the mounting bolt. ADVANTAGE - The technique dampens oscillations in bobbins which bear against the drive roller with only a light pressure, and rotate at high speeds, to give a consistent bobbin winding.

Title: Network protection circuit for monitoring and isolating due to fault - measures current difference between at least one outgoing lead and neutral lead to detect fault or earth leakage
Inventor: BERTHOLD RAINER DIPL PHYS
IPC: H02H3/33
Filed: 1991-07-20
Abstract: The signal from a sensor in the protection circuit corresponds to a current difference in the network outgoing (11) and return leads (12) which is delivered to an evaluation circuit. The output signal of the evaluation circuit controls a switch (63) for the opening of the contact points (47, 48) located in the outgoing and return leads. The supply voltage and the switching power are derived from a capacitor which is continuously charged by a long-life battery. The protection circuit measures the charge condition of the capacitor. A latch for the contact points in their switched off state has a plunger (63a) of insulating material which can be pressed by a drive against the contact points to isolate them. The drive is activated by the measuring unit, as soon as a drop below a threshold value of the capacitor charge is detected. ADVANTAGE - Earth leakage protection switch or differential current protection switch isolated with mains failure or neutral lead break.

Title: Acetylene absorption from crude ethylene@ and opt. ethane gas mixt. - in plate column with external mixer for absorbent and condensed prod. to prevent frothing
Inventor: HAEHN PETER CLEMENS DIPL ING
IPC: C07C7/11
Filed: 1991-08-23
Abstract: Removal of C2H2 from a crude 2 C hydrocarbon gas mixt. (I) is carried out by scrubbing with an absorbent (II) in an absorption column with plates, which is supplied with (I) at the bottom and regenerated (II) at the top; discharging charged (II) from the bottom and passing this to regeneration; and recovering a C2H2-free prod. gas stream (III) from the top, if necessary after sepg. and recycling a condensate to the absorption column. If a condenste (IV), consisting of condensed (II) and (III) is recycled, a side stream (IVA) of (IV) can be introduced between the inlets for (I) and (II). The novelty is that a liq. C2H2-free 2 C stream (V) and/or (IVA) is mixed with (II) outside the absorption column and the mixt. is passed into the column. Pref. mixt. contains 10-70, pref. 30-50 (wt.)% (V). Mixing is carried out in a static mixer and the mixt. is injected into retained (frothed) (II) in a mixing zone between 2 plates, pref. in the lower 2/3, esp. the lower half of the column. The mixt. is introduced at a temp. below that of (II). The mixing zone and outlet pipe are filled with packing material. USE/ADVANTAGE - The process provides a simple way of avoiding froth formation in the column, which causes unstable operation and break-through of C2H2 into (III). It is used in the recovery of C2H4 from a crude gas also contg. C2H2 and opt. C2H6, 3C hydrocarbons and/or CH4 and is also suitable for removing all acetylenes from hydrocarbon streams, e.g. methylacetylene from a 3 C stre

Title: Home financing management system
Inventor: ASHER ANTHONY
IPC: G06F/
Filed: 1991-11-04
Abstract: Home financing is provided by means of a salary linked mortgage. A borrower repays a loan from a lender by paying a percentage of his salary, irrespective of the manner in which his salary varies, for a predetermined period. The percentage may be the same for the entire period or it may vary in a predetermined manner. The lender may also unilaterally vary the percentage if the borrower does not make payments on specified dates. Conveniently, a convenience percentage value is used for each financial year and, if necessary journal entries are made.     The system is managed and supervised by data processing equipment which stores information characterising each borrowers account, inputs details of repayments from the borrower and his employer, generates an updated schedule percentage for each account at the end of each month and communicates the updated schedule percentage for each account at the end of each month.

Title: Ascertaining running irregularity value of IC engine - deriving correction term from medians formed from time spans differences of ignition phases
Inventor: KLENK MARTIN DIPL ING
IPC: G01M15/11
Filed: 1991-11-26
Abstract: At least one crankshaft angle sector related to the t.d.c. of each cylinder before its ignition phase is set out. The sector time spans for each ignition phase during which the given crankshaft angle sectors are covered are measured. A first difference is formed from two sector time spans for each ignition phase. This provides a basic running deviation term. A correction term for running deviation is obtained. The running deviation value is obtained by correcting the basic term through subtraction of the correction term. The correction term is derived through medians formed from several sector time span differences for ignition phases of interest. ADVANTAGE - Median deviation ensures that not only linear but also at least a partial class of non-linear accelerations and decelerations can be fully compensated. Running irregularity value not affected at all.
