Title: Aluminium honeycomb structures coated with polymer - formed by coating anodised sheet, selectively bonding and forming honeycomb core
Inventor: DONNELLY DENNIS J
IPC: E04C2/36
Filed: 1977-02-10
Abstract: Mfr. of an Al honeycomb core which is corrosion resistant and stable in its environment is described. Al sheet is anodically treated in H3PO4 to oxidise the surfaces so that it can be coated with a polymer. The anodic treatment is carried out at 24-71 degrees C for 6 s.-30 mins. under a potential difference of 5-50 volts and using a H3PO4 concn. of 5-50%. A fien coating of an organic-resin-based material is applied to the surfaces and hardened. An adhesive is applied to the coated Al sheet in selected places to form nodal bonds in the honeycomb structure. The sheets are then stacked together and the adhesive is hardened so that the sheets are linked together. The stack is then formed into a honeycomb core. A cladding sheet is fixed on to the surfaces of the opposite edges with an adhesive which wets the surfaces of the coated Al sheets to form beads of adhesive stretching into the interior of the honeycomb cells. The good adhesion of the adhesive on the interior of the cell and the sides of the cladding gives a superior bond. The corrosion resistance of the structure is improved and the oxide at the surface resists hydration.

Title: Energy recovery system e.g. for ice rink - extracts heat by pump from water tank then reheats from surrounding sources
Inventor: CREDE HELFRIED
IPC: F25B30/06
Filed: 1977-04-04
Abstract: The energy recovery system is particularly for recovering heat from surrounding sources with a temp. above 0 deg. C. Heat is extracted from these sources by a coolant, so as to form ice. The heated coolant is led away on the heat pump principle. From the surrounding sources heat is extracted from a water tank, thus cooling it to freezing point and forming ice. This is then re-melted by heat conducted from the surrounding sources. Intensive heat exchange between tank and sources can be effected by heat exchangers, solar energy collectors etc., and heat can also be provided by domestic drain water, or by electric nigh-storage heaters. Ice can be removed continuously or periodically from the vapouriser surface in the coolant circuit, and salt can be added to the water to form porous ice.

Title: Exposed height control for submarine periscope - combines actual depth, desired depth and periscope height signals for application to comparator for providing control variables
Inventor: KAYSER PETER DIPL ING
IPC: B63G8/24
Filed: 1977-12-12
Abstract: The exposed-height control for telescopic equipment in submarines is primarily for use when snorkeling using automatic depth control. Electric switching networks, one for each periscope part, evaluate a common actual depth signal against combined desired boat depth and individual periscope part height signals. Their desired value output is fed after passing through a variable gain amplifier, to a comparator in the form of e.g. a sum-and-difference amplifier, where it is compared with the actual height feedback. The comparator output is converted into a correction signal for the periscope positioner (A) with the aid of error direction and movement range monitors.

Title: Milking procedure to obtain blood-free, sterile milk - involves diversion of milk flow into adjacent container for short period after start f milking (HU 28.11.77)
Inventor: TAMAS KAROLY DIPL ING
IPC: A01J7/00
Filed: 1977-12-30
Abstract: The aim of the miling procedure is to obtain blood and discharge free, sterile milk. After the start of the mechanical milking, the milk flow is fed into an adjacent container (4) during a given period and/or during the time that blood or discharge appears in the milk flow. On establishing the milking, the milk is fed into a main container (5). Specifically, the milk is fed into the adjacent container (4) for 3 to 10 seconds after the start of the mechanical milking. Alternatively, this division can take place for a period of 2 to 8 pulsations. The colour of the milk is also continuously controlled.

Title: Rocker switch with contacts in insulating housing bottom - has slit in bending spring contact, forming two shanks, one shank end carrying contact
Inventor: PISTOR MAX
IPC: H01H23/12
Filed: 1978-01-13
Abstract: The housing bottom also contains outwards protruding terminal tags. An insulating switch rocket pivots about an axis in the housing and has an inside protruding switching finger for moving a bending spring contact in its made and broken positions. The contact closing is the result of the spring force of this contact. The rocker movement is limited by housing stops. The bending spring contact (4) has a longitudinal slit forming two shanks (4c, 4d) at least over its part. The end of the shank (4c) supports the contacting position (4a) for cooperation with the stationary contact (2). The other shank (4d) forces in this position the first shank from the switching finger (5a) by its own spring force.

Title: Nuclear reactor, side reactor blocks exchange - by two manipulators replacing absorber rods and sheet piling retaining fuel element pile
Inventor: FRITZ ROLF DIPL ING DR
IPC: G21C19/20
Filed: 1978-04-21
Abstract: The blocks of the side reflector in the cavity of a gas-cooled, high temp. reactor contg. a pile of spherical fuel elements are exchanged by replacing the absorber rods in the iron-clad tubes near the border by a manipulator. This is used to extract some of the ceiling reflector and any other metallic obstructions. A second manipulator is used to push the overlapping sections of a sheet piling between side reflector and fuel element pile. The first manipulator then extracts the side reflector blocks one-by-one. Parts of the side reflector can thus be exchanged without having to remove the fuel elements from the core or any major components such as heat exchangers. The down -times of a high-temp. reactor are considerably reduced.

Title: Heat engine using low grade energy - has working fluid compressed before being returned to heat exchanger for cooling
Inventor: SOELCH ROLAND
IPC: F01K25/00
Filed: 1978-05-26
Abstract: A working fluid e.g. paraffin is contained in the shell of a heat exchanger. The tubes are traversed alternately by a heating and a cooling liq. which are admitted by coupled valves. On heating the fluid expands and the additional volume passes through a control valve and an afterheater to an engine in which it does useful work. The cooled exhaust from the engine flows into a container from which a compressor returns it through a control valve into the heat exchanger on the cooling cycle of the exchanger. The two control valves are moved in time with the process cycle.
