Title: Transfer membrane apparatus
Inventor: BELLHOUSE BRIAN JOHN
IPC: A61M1/14
Filed: 1983-12-07
Granted: 1987-09-17
Abstract: Transfer membrane apparatus incorporates a number of parallel channels, each channel comprising a first conduit (5) for a first fluid formed between two closely spaced transfer membranes (6). The outer face of each membrane is supported against a profiled plate (7) such that second conduits for a second fluid are provided one on each side of the first conduit (5) between a respective membrane (6) and supporting plate (7). The supporting plates (7) are mounted spaced apart in a stack with the double membranes between each adjacent pair of plates. The transfer membranes (6) are provided as parts of a continuous web (6) of transfer membrane material which is folded in concertina fashion. One set of folds (11) each extends around the front edge of a respective plate (7) and the other set of folds (12) each closes a respective first conduit (5) adjacent to the rear of the stack. Each first conduit (5) is sealed along a narrow zone (16) extending from a point substantially halfway along the front of the stack towards, but short of, the membrane fold adjacent to the rear of the stack. Thus, each first conduit (5) is substantially U-shaped, extending from one side of the front of the stack towards and across the rear of the stack and back to the other side of the front of the stack, or similarly W-shaped. Inlet and outlet manifolds for the first fluid are provided alongside one another across the front of the stack.

Title: Method and arrangement for welding together the ends of rolled strips of finite lengths to form a strip of an infinite length during further processing of the strip
Inventor: ANGERER KLAUS
IPC: B21C47/24
Filed: 1985-08-02
Granted: 1989-12-28
Abstract: The average winding diameter of a finite roller band length wound on a supply coil is increased by having the roller band rewound from the supply coil to a storage coil of a larger than the winding diameter, which encloses the supply coil concentrically. During the uncoiling of the band stored on the storage coil for purposes of a continuous manufacturing operation, a welding device is arranged in the annular area between the external diameter of the supply coil and the internal diameter of the storage coil and welds the band trailing end of the storage coil together with the band and leading end of the supply coil. The contents of the supply coil are then taken over by the storage coil, and while this material is uncoiled, a further supply coil is inserted and its leading edge welded to the end of the storage coil.

Abstract: Improved accuracy in solution conductivity or resistivity measurment uses a center-sampling technique in which an AC drive is applied to a conductivity cell and the conductivity cell voltage is sampled during a predetermined time interval in the center of a half cycle drive waveform. The effects of cell capacitance, and particularly the electrode-solution capacitive, are compensated by periodically sampling during a second time interval which is different from the first interval. Based upon the difference between the sampled voltages in the first and second intervals, a correction to the measured conductivity or resistivity is made to compensate for capacitance induced errors.

Both signals are provided by respective synchronous rectifiers (S1,S2) supplying respective inputs of a comparator (VL) with its output fed to the amplification control (C) for the regulation (RG). Pref. the regulator amplification is adjusted by supplying a reference frequency (fo) to the inputs of the two synchronous rectifiers (S1,S2), with the sinusoidal frequency generator signal superimposed on the regulation parameter (W). The adjustment of the amplification is maintained until the regulation amplitude (x) and the regulation difference (xd) are the same.

Abstract: Methods and compositions for increasing stability of enzymes in oxidant dry bleach are disclosed. Enzyme stability is adversely affected by increased temperature, humidity, and the presence of strong oxidants, such as peracids. The invention provides enzyme stability in the presence of oxidant bleaches by coating or encapsulating the enzyme, while providing enzyme solubility suitable for use in bleach mixtures upon introduction to an aqeuous medium. Particularly, alkali and neutral materials act as protection agents, which neutralize oxidant species before they contact and denature the enzyme. Other standard bleaching composition adjuncts such as builders, fillers, buffers, brighteners, fragrances may be included in the enzyme-containing oxidant bleach composition in addition to the discrete coated enzyme granules.

Abstract: A table (11) can be stopped in a vertical movement with respect to a fixed guide (15) by selectively engaging an engagement and locking element (21) in form of a angled lever having a control arm (33) and a stopping and locking arm (31) with adjustment and stop elements (19) secured on the vertically extending second part (15). Upon movement from a predetermined position, the control arm (33) is engaged in a guide track (51) of the engagement and locking element, permitting unlimited movement in a direction away from an adjustment and stopping shoulder (37) on the abutment and stop element. Upon reverse direction, however, the control arm engages a first can (47) which moves the locking arm (31) against the abutment shoulder (37). To release the locking arm from the abutment shoulder, it is only necessary to make a short movement counter the locking direction which will engage the control arm in a second cam to release the lock, and the guide track (51) then guides the locking arm of the engagement and locking element clear of the adjustment and stopping shoulder upon again reversing direction of movement.
