Title: Protein yeast and Saccharomyces cerevisiae prepn. - from whey and skim milk by combining lactic acid fermentation and yeast cultivation
Inventor: MOEBUS OTTO DR
IPC: C12N1/18
Filed: 1976-03-16
Abstract: Single cell protein and Saccharomyces cerevisiae are prepd. from whey and skin milk permeate by combining lactic acid fermentation with yeast cultivation. Process takes place by mixing the permeates with a pre-determined amt. of yeasted cell-free liquid. Lactose in permeate is then fermented completely to lactic acid by buffer activity and by supplying growth materials specific to the yeast. Permeates of sugar-, starch- and cellose-contg. aq. substrates and other C-sources may be yeasted by same process. Process may also be coupled with other anaerobic fermentations, leading to prodn. of organic acids, e.g. AcOH. Coupling of anaerobic acid prodn. with yeasting by a liquid cycle provides a soln. for technological problems in waste water processing.

Title: Audio signals synchronising and processing system - for multichannel recording records code signal which represents channel being used
Inventor: FREUDENSCHUSS OTTO DIPL ING
IPC: G11B5/027
Filed: 1976-04-15
Abstract: The synchronising and processing system, for multi-channel audio signals recorded on magnetic tape, records a code signal in the tape at the same time as the audio signal or in a separate process. The code signal is made to refer to a given channel and is used to identify and assign that channel. The parameters of an audio signal in any given channel can be altered by a control circuit as required. The audio signals and the code signals are processed in parallel by the multichannel replay circuitry. The system allows e.g. tape recordings to be synchronised to e.g. cine film.

Title: Dual purpose filter cartridge with adsorption section - constructed as concentric annuli with perforated walls and means for recharging the adsorbent
Inventor: KUWAJIMA SOICHI
IPC: B01D53/04
Filed: 1976-04-17
Abstract: A filter cartridge has a filtration element and an adsorption element arranged in two concentric annuli with intervening perforated walls. The flat ends of the cartridge have apertures through which the adsorbent may be removed and replaced with fresh material. In the clarification of liqs. where fine particles, colouring matter, water droplets and so on are present as well as filterable material, they are removable only by adsorption. The cartridge is a dual-purpose one of simple and cheap construction, and it allows the adsorbent to be replaced without affecting the filter element, this allows operating economies since normally the adsorbent will need to be exchanged before the filter medium is exhausted.

Title: Power press operator hand protection - comprises closable half shell clamps closing around wrists before press downward stroke
IPC: F16P3/08
Filed: 1976-07-02
Abstract: The safety installation is for hand protection of the operator of a two-hand controlled metal working power press during the dangerous closure movement of the press tool. Clamps maintain the hands outside the immediate working area. The control for the closing and opening of the clamps is determined by the control of the press stroke so that the clamp closure occurs before commencement of the press stroke. It opens only when the press tool is at rest at its top dead point. The clamps (13) comprise closable half shells (11, 12) encircling the wirsts of the operator. They are bent in the form of a sickle or crescent, and are connected at their lower ends.

IPC: B23B19/02
Filed: 1976-10-18
Abstract: The fastening device has a chuck (1) for accommodating a shank (20). There are corresponding reference surfaces on the device and shank in order to fix the height and angular position of the shank. An end face of the device and a bolt (5) arranged on the end face and parallel to the axis of the chuck (1) form the reference surfaces of the device for height and angle, while the shank (20) has a radially projecting pin (21) which can be pressed by means of a spring-loaded clamping member (6) against end face and bolt (5). The clamping member can be a clamping lever (6) which is rotatably mounted at the side of the bolt (5) and has a wedge surface in order to overlap the pin (21) with this wedge surface. To adjust the zero mark for the angle, the bolt (5) can be rotatably mounted and locked in the wall of the chuck (1) by means of a stem eccentric to its axis. A fastening device of simple design, in particular for electrical discharge machine tools, is thus created. <IMAGE>

Title: Cutting burner control - with rotary pick=up for turning tubes with intersecting curves as function of burner movement (NL 29.5.78)
Inventor: TOMENENDAL HANS
IPC: B23K7/00
Filed: 1976-11-25
Abstract: A cutting burner, e.g. for cutting intersecting curves on tubes of different radii which meet at an angle, is controlled by a synchro receiver on a slide. A revolving bolt on the parallel lever linkage actuates a transducer (rotation pick up) which produces output signals for the rotation of the tube through a certain angle. This is a simple system for producing precise intersecting curves by controlling both the axial movement of the cutting burner and the oscillating rotary movement of the tube.

Title: Visual or acoustic signal generator on loose ski - has switch arm operated by ski boot and switching=on signal generator when released
Inventor: HASSE ROLAND
IPC: A63C11/00
Filed: 1976-12-22
Abstract: An acoustic or visual warning signal on a loose ski-which could endanger other skiers -is produced by a battery operated attachment on the ski. It can be an integral part of the deflector bracket which is normally located near the front end of the ski. The signal generator is switched on when the ski boot comes off the binding during a fall. This is done by a spring-loaded switch arm which is normally held in its open position when the ski boot is located in the ski binding. The warning signal is also useful to find the ski if it comes to rest, covered up in soft snow.
