Title: Enzymes recovered from substrate-degradation prods - esp. in starch hydrolysis by elution from a cationic exchange resin
Inventor: SCHWENGERS DIETER
IPC: C12P1/00
Filed: 1974-08-21
Abstract: Process for separating enzymes from aw. solns. contg. small org. molecules (II) comprises (i) passing soln. over an ion echange resin, (ii) eluting with water and (iii) collecting an enzyme rich fraction before (II) are eluted. Pref. the ion exchanges is a cationic rein loaded with metal and/or NH4 ions and both resin and soln. have pH 3-9, esp. pH at which the enzyme has optimum activity. Particularly for recovering hydrolases, invertases or isomerases used in conversion of polysaccharides to mono-, di- or oligo- saccharides and to remove lactose from cows milk (to give a product acceptable to persons lacking Betha-galactosidase). The enzymes are not denaturated so may be recycled and where the soln. contains >=1 enzyme these may be recovered separately.

Title: Exposure control for process equipment - using relative measurements for predetermined standard subjects and negatives
Inventor: SIEGEL HANS
IPC: G03B27/72
Filed: 1974-09-26
Abstract: The process equipment is fitted with a simple exposure control with a simple memory. Standard negatives and masters are first passed through the equipment to determine accurate exposure readings. The machine is then closed and the required negatives and masters are fed in and their exposures calculated by the control in a comparative manner, referring to the standard readings. The process can be applied to printers or photocopiers, using relatively simple exposure meters. The enlargement factor is given by a simple formula (extension along axis/focal length)2.

Title: Remote control receiver has preliminary tester for decoders - to prevent incorrect reception of instruction telegrams
Inventor: BEYER WILHELM
IPC: G08C25/00
Filed: 1975-01-15
Abstract: The remote control receiver has a means of preventing incorrect reception of an instruction telegram which may then be used as an erroneous reference for comparing with other received instructions. Different categories of incoming information are passed to different address decoders. Each decoder has a control memory that responds when its decoder is occupied. All control memories are coupled to a testing system that tests the receiver with test pulses at the beginning of each received pulse telegram. A coincidence gate receives the output signals from alternately-responding control memories. A NOR gate may be used to produce either logical '1' or '0' signals.

Title: Plastic thread braided roll for hair curlers - is made of helical group of threads ultrasonically welded to axial group of threads
Inventor: MICHEL VOLKER ING GRAD
IPC: B29C65/08
Filed: 1975-04-14
Abstract: Braided rolls with a rotational symmetry for use as hair curlers are made of two cross-over groups of threads of polypropylene, polyethylene, polystyrene or acryl.

Title: Water saving system for toilet cisterns - includes speeding up downward motion of bell type cut off valve to reduce expelled water volume
Inventor: PIERNICKE KLAUS
IPC: E03D1/14

Title: Protective coating applicator for wood - has fabric roller made of cotton fabric discs to apply softened plastics resin
IPC: B05C1/08
Filed: 1976-05-17
Abstract: The machine for applying a protective coating to wooden surfaces consists of a base (12) carrying supports (14) for a roller (15). A hopper (11) is mounted on a slide (18) which travels on the transverse beam (20). The hopper is filled with blocks of synthetic resin which press on the surface of the roller (15) and are softened by the heat generated by friction. The roller (15), which is made of discs of cotton fabric, then spreads the resin over the surface of the wooden board (10) which has been preheated by passing under the heater (27). The board (10) is then passed under the rotating cylindrical brushes (28, 29). Using plastic resin coatings eliminates the drying time which is necessary with coatings applied in liquid form.
