Title: Swimming pool wave generation system - uses pneumatically or hydraulically swelling pockets formed by flexible side mats
Inventor: SCHUSTER SIEGFRIED PROF DR ING
IPC: E04H4/00
Filed: 1976-09-13
Abstract: The wave generator in a swimming pool uses a hydraulic or pneumatic system for effecting periodic water displacement in the waveforming area. Wave generation is effected all over the usable pool area, by inflation of pockets formed by the solid pool sides (2), below the water, and by flexible mats (3), connected to the edges of these with a sealing effect. Water or air is periodically introduced and removed through apertures (5) in the sealed areas, so that the mat bulges out and causes the adjacent water to move, forming wave crests (6) and valleys (7). This involves neither loss of part of the usable pool area, nor temporary inactivity of mechanical fittings.

Title: Continuous sucrose conversion to iso:maltulose - during continuous fermentation of iso:maltulose-forming microorganisms with addn. of sucrose-contg. solns.
Inventor: CRUEGER WULF DR
IPC: C07H3/04
Filed: 1978-02-14
Abstract: Sucrose-contg. solns. are added continuously to a medium in which isomaltulose-forming microorganisms (I) are cultivated continuously. Cultivation si continued in a standard manner. After sucrose conversion, the soln. is separated from the microorganism mass, purified by a standard method and/or crystallised. Isomaltulose is an intermediate for the prepn. of glucopyranosido-1,6-mannitol and glucopyranosido-1-,6-sorbitol. Both cpds. may be used as sugar substitutes. The bacterial mass separated may be used as cattle fodder. The cultivation of the microorganisms and sucrose conversion to isomaltulose take place simultaneously. The bacteria grow quickly on reaching the steady state. 90-100% conversion to isomaltulose is achieved. Sucrose-contg. plant juices, cheaper than pure sucrose-contg. solns., may be used. Bacterial growth and conversion can be conrolled by only one critical parameter, e.g. CO2 content in waste air, O2 partial pressure in culture soln. and/or conversion rate. Fructose and glucose are formed during conversion to isomaltulose, obviating the need for adding carbohydrate sources.
