IPC: C02F3/10
Filed: 1973-01-10
Abstract: An effluent treatment plant consists of many parallel perforated elements, suspended vertically, over which the water is allowed to flow in a thin film.

Title: Blood sample bottle stopper - has inner circular portion forming seal against neck and concentric external skirt
Inventor: BALL GARETH DENZIL
IPC: B65D41/02
Filed: 1973-09-13

Title: Vehicle ferry load fastening hook - has apertures on both ends and serrated V-shaped jaw arrangement for gripping rope end
Inventor: PFAHL JOACHIM
IPC: F16G11/14
Filed: 1973-10-08
Abstract: The problem of fastening securely loads on cargo ships or ferries and preventing them from listing is being handled by the present arrangement. The hitherto usual method of fastening cars on ferries by slinging ropes around the bumper arms has the disadvantage that in rough seas the wheels still have the possibility to change their position by sliding along the floor, coming possibly into contact with adjacent vehicles and damaging them. The present design envisages stretching the rope from the aperture at the far hook end through an anchoring ring provided at the side of the vessel, then threading it through the opening in the near hook end and finally to wedge it between the serrated surfaces of the V-shaped jaws. The hook is applied into the openings of the wheel, preventing slipping.
Patent DE-2353447-A1 (DE)
Title: Combustion engines ignition system - has steel block in brass collar fixed to shaft and triggering ignition pulses
Inventor: SCHRUMPF HANS
IPC: H02K21/38
Filed: 1973-10-25
Abstract: The ignition system, for combustion engines, has a steel block set into the circumference of a brass sleeve fixed to the engine shaft. A magnetic pulse generator is fixed to the engine housing and its core-ends face the brass sleeve. Each time the steel block passes the generator the latter produces a pulse which is used to control the switch that passes the ignition voltage through via the h.v. transformer to the spark plug electrodes. Steel and brass are chosen because they can have approx. the same density and therefore do not upset the balance of the shaft.

The method is a simple process for producing heteropolysaccharide-10, which is esp. useful as a thickener in foodstuffs such as salad cream, puddings, etc., as viscosity modifiers and moisture conservation agents, and for producing printing pastes for textile printing. The organism Erwinia tahitica (ATCC 2171) is new and is described in detail. Fermentation is generally carried out for 45-60 hours using maize starch hydrolysate as carbon source. The heteropolysaccharide may be recovered e.g. by precipitation with a low alkanol.

Title: Printing of cellulose fibres impregnated with azoic coupling agents - with vinyl sulphone reactive dyes protected by paraformaldehyde
Inventor: FEESS ERICH DR
IPC: D06P3/66
Filed: 1974-03-27
Abstract: Cellulose fibre fabrics impregnated with (A) coupling components of development dyes, are printed with (B) reactive dyes of vinyl sulphone type protected by 2-20 (3-15) g/kg. of paraformaldehyde in the printing past. Where (A) contains a reactive methylene gp., e.g. in acyl acetamino arylide coupling components, this reacts with formaldehyde and reaction with (B) which interferes with its dyeing properties is prevented. The smell of formaldehyde and its escape into the dye works, where it can affect other treated fabrics awaiting dyeing, are avoided by use of paraformaldehyde.
