Title: Process for applying reaction-hardening two-component or multicomponent coating materials to underwater surfaces
Inventor: HEINZE PETER
IPC: B05D1/02
Filed: 1982-07-08
Abstract: A process is disclosed for applying reaction-hardening two-component or multicomponent coating materials to underwater surfaces, wherein a coating material with a high wetting power is applied in finely dispersed manner by low pressure or airless spraying, or centrifuging. The coating material used may be a solvent-free, low viscosity, sprayable epoxy resin-hardener mixture containing active corrosion inhibiting pigments and/or inert fillers. The high wetting power of the coating material gives firm adhesion thereof to the underwater surface to be coated.

Title: Worm pumps for pneumatic conveyors
Inventor: STAMER WALTER
IPC: B65G53/48
Filed: 1983-03-25
Abstract: In a worm pump, for charging pneumatically transportable bulk material into a conveyor duct, of the kind having a worm mounted on each side of a delivery housing 2 and a nonreturn valve 3 in the delivery housing, the delivery housing is constructed in the form of a spiral, as viewed in the pump cross-section. This expedient helps to reduce the friction losses which occur when bulk material is discharged from the delivery housing, and in consequence helps to reduce the energy requirements of worm pumps with twin worms. Air is supplied to the conveyor duct via air permeable walls 7, 8. <IMAGE>
Patent GB-2118757-A (GB)
Title: Audio transducer
Inventor: ASHWORTH-JONES ALUN DAVID
IPC: G10H3/18
Filed: 1983-01-18
Abstract: An audio transducer, for a musical instrument, incorporates a sensitive piezo-electric element 5 of composite construction, operating in a simple beam mode. The element responds to sound vibrations in two opposing plates 1, 7 which are separated by rigid supports 8, and between which the element is supported 2, 6 so that it acts under controlled static pressure. This pressure is determined by the fixed spacing of the opposing plates, together with the nature of the material of the fulcrum 6, and the flexibility of the element. These factors are arranged to allow the minimum static pressure on the element consistent with efficient transfer of sound to the element through its own supports. The element is thereby enabled to operate under constantly optimum conditions, despite the extremes of pressure to which the device as a whole may be subjected in its normal position beneath the saddle of a stringed instrument. The result is the production of a high-level audio signal. <IMAGE>

Title: Dampers for ventilation systems
Inventor: MAGILL ROBERT JOHN
IPC: F24F13/15
Filed: 1983-09-09
Abstract: The damper is constructed to enable a simple removal of a damaged blade (14). A retaining member (30) at one end of the damaged blade is pivoted away from the blade so that the blade end can then be moved downwards, clear of projections (28) which engage a slot (26) in an end plate (20), fixed to the blade. Once this has been done, the blade can be shifted in a lengthwise direction so that a plate (38) at the other end of the blade is moved clear of projections (28) on its respective end support (16). A new blade can then be readily fitted by reversing the sequence of operations described above for the removal of a blade. <IMAGE>

Title: Vehicle hydraulic systems
Inventor: REYNOLDS DESMOND HENRY JAMES
IPC: B60T13/16
Filed: 1984-04-18
Abstract: In a vehicle hydraulic system of the open centre kind, hydraulic fluid for operating vehicle services is circulated continuously, normally by an engine-driven pump. A closed centre booster (6) for the brake or clutch which requires a substantially constant pressure differential to operate it, is included in the open centre system, the pressure differential being provided by a fixed restriction (5) in the open centre circuit, rather than an accumulator supplied by the pump. The fixed restriction (5) may be operative when the pump is operative Fig. 2, or only when the booster (6) is operative Fig. 3. The booster (6) is arranged so that in operation, high pressure fluid entering a boost chamber (16) displaces an equal volume of fluid from a forward chamber (17) into the system. The booster (6) may also include a one way valve (18) allowing flow of fluid from the forward chamber (17) to the booster chamber (16). <IMAGE>

Title: Method for determining galactitol
Inventor: IZUMORI KEN
IPC: C12R1/38
Filed: 1986-06-30
Abstract: Galactitol levels in body fluids, e.g. blood or urine, can be determined by a method which comprises treating in vitro a sample of the body fluid with a bacterium capable of producing D-tagatose from galactitol, and measuring the resultant D-tagatose. Typically, the bacterium is of the genus Arthrobacter, preferably, Arthrobacter globiformis ST-48 FERM P-7592 or of the genus Pseudomonas. The method is useful for detecting galactose dysbolism. The D-tagatose may be determined using Fehlings or cysteine- carbazole reagent or enzymatically using galacticol dehydrogenase.
