Title: Terugwinning van de kinetische energie achter schepen.
Inventor: JOHANN JOSEPHUS HOF
IPC: B63J3/04
Filed: 2015-04-02
Abstract: De uitvinding heeft betrekking op het feit dat voortstuwing van schepen zorgt voor sterk stromende watermassa's vlak achter het schip. Veel van de energie komt terecht in het water. In die turbulente watermassa zit dus energie dat nu nog ongebruikt in de watermassa van het kielzog van het schip verdwijnt. Met een geheel nieuw soort waterkrachttoestel, het 5 scheeps-waterkracht-toestel, dat kort achter en flexibel verbonden aan het schip mee gaat, wordt deze kielzog-energie teruggewonnen. Het schip wordt er niet door wordt afgeremd, zelfs wat meer opgestuwd. De omarming van het scheeps-waterkracht-toestel bestaat uit stalen armen die de scheepwaterkrachttoestel zo horizontaal mogelijk houden. Het toestel wordt met een kabel- en lier-systeem continue op waterspiegelniveau gehouden. Rondom het 10 onderste deel van de kap, op waterniveau, wordt een ring van drijfmateriaal aangebracht, waardoor en opwaartse kracht daarvan wordt benut. De generator wordt in de behuizing van scheeps-waterkracht-toestel, onder de kap, ondergebracht. De schoepwielen en de generator zitten op één centrale as. De verschillende schoepenwielen zijn kleiner in diameter naarmate ze verder van de midden-aslijn van het schip af liggen en de schoepen zelf dan zijn ook 15 kleiner. Het toestel kan binnenboord worden gelierd. De opgewekte elektriciteit wordt gevoerd naar het schip en naar de scheepsaccu's in de machinekamer geleid. De elektriciteitsbehoefte van het schip kan er mee worden voorzien, waardoor het gebruiken van dieselolie daarvoor wordt verminderd. Veelal is er zelfs elektriciteit over om aan derden te kunnen leveren.

Title: Film processor with automatic control of strength of chemical - has sensing element in tank providing signal to control solenoid in replenishment circuit
IPC: G03D3/06
Filed: 1974-11-28
Abstract: Automatic film processing machine where the strength the process chemicals are kept constant. A developer tank (1) is coupled to a vessel (5) which contains the replenishment solution and supplies it via a flow meter (6) which indicates the flow speed of the liquid in the vessel. The flow of chemical is controlled by a unit (7) via a solenoid valve (8) which is linked to a sensing device (14). The piping system for the liquid is arranged so that about half of the liquid flows through a mixer vessel and the rest to the developer tank. The sensing element will produce a signal indicative of the strength of the chemical in the tank and this signal is used to control the solenoid valve, which in turn controls the replenishment flow.

Title: 2,6-Di-tert-butyl 4-methyl phenol prepn. by hydrogenolysis - of N,N-dimethyl 3,5 -di-tert-butyl 4-hydroxy benzylamine with prod. as solvent
IPC: C07C37/50
Filed: 1976-06-08
Abstract: is prepd. by catalytic hydrogenolysis of N,N-dimethyl-3,5-di-t-butyl-4-hydroxy benzylamine in the presence of a catalyst contg. Ni, Ti, Al, and using, as solvent, 2,6-di-t-butyl-4-methylphenol. The product is used as a stabiliser and anti-oxidant, e.g. for natural and synthetic rubber, polyethylene and polypropylene fibres, and food products. The known process above is carried out usually in an organic solvent e.g. decalin as in GB 1229480. However, in the reaction conditions, some resin is formed and the isolated product contains about 5% resin. The recovery of solvent is complicated and the product must be purified, e.g. by distillation, or crystallisation, for food uses. The above modification avoids any solvent recovery stage and gives a yield of product about 98.4%, which is satisfactory for food use without further purification.

Title: Inclined swivel support for horizontal shaft liquid impeller - has aerofoil near impeller to give vertical force balancing wind reaction by use of tip vanes or annular shroud
IPC: F03D11/04
Filed: 1978-02-03
Abstract: The arrangement is intended for supporting a wind-driven impeller (3). The support arm (4) is rotatable about horizontal and vertical axes (in D), and a fixed aerofoil wing section (6) is arranged upstream or downstream of the impeller. The arrangement is such that there is equilibrium between the couple caused by the horizontal reaction of the wind force on the impeller and vertical reaction of the wind force on the aerofoil section. The vertical reaction may, alternatively, be achieved by having the impeller axis inclined at an angle to the horizontal, having an annular shroud around the impeller or using an impeller with tip vanes.

Title: Hose for extracting undisturbed samples from earth - is given coating allowing transverse stretch without compressing sample
IPC: E21B25/06
Filed: 1978-03-23
Abstract: Hose for use in a device for extracting an undisturbed sample of earth from below ground level, is prepd. by drawing the hose through a bath of fluid whilst air is blown against the inner surface of the hose. A circular knitted hose is used, which, whilst it is being drawn through the bath is under longitudinal tension. Until the coating is stabilised, the longitudinal tension and the desired dia. of the hose are maintained. The fluid may be a monomer which polymerises at a temp. higher than that of the bath, and stabilising of the cladding on the hose is effected by polymerisation; the temp. being raised to a point above that of the bath, sufficient to initiate the reaction when catalysts are added. The vaporising of the solvent or the course of the polymerisation is pref. effected by hot air blown into the hose, the pressure of the air being sufficient to maintain the dia. required at least in the unstabilised zone. The hose is both flexible and elastic in the transverse direction and is esp. suitable for taking samples. IT stretches sufficiently for folding in the chamber of the sample taking device, without applying load to the sampel.

A digital memory unit (7) works with a read-out device for recording signals from it in according with an ample recognition programme, for the production of an automatic determination of the significant presence of these signals. A coded signal indicating the diagnostic result can then be interpreted.
