Title: Boat laterally steerable by pump with three=way valve - takes in water and propels it at one or other side of hull below water line
IPC: B63H25/46
Filed: 1980-01-29
Abstract: The arrangement is intended for moving a boat in lateral direction by propelling water through an opening below the water line in the side (17,18) of the hull. It comprises a pump (1) which takes in (via 5) water from outside and passes it through a three-way valve (10) whose outlets (11,12) are connected (13,14) to the respective outlets in the hull. The valve may have a cylindrical housing containing a rotatable plug with L-shaped port whose radial portion connects with one or the other outlet (11,12). The plug may consist of an L-shaped pipe bend with two slide shoes spring-loaded in radially outward direction against the cylindrical housing wall.

Title: Glazing panels for greenhouses - with a glass pane having a light transmitting plastic film attached to the edges to leave a permanent air gap between the two
IPC: A01G9/14
Filed: 1980-02-27
Abstract: Glass panels for greenhouses are provided on the inward- facing side with a light-transmitting film which is attached to the periphery of the panel such that a permanent air gap of at least ca. 1.5 cm is maintained between the glass and the film. Pref. films are (UV-stabilised) polypropylene, polyethylene or polyester with a transparency of at least 90%, and are adhesively bonded to the glass panels round the edges. Pref. the air gap between the glass and plastic film is 1.5-2.5 1-3 cm. The plastic film is bonded to the glass pref. e.g. with adhesives based on polyvinyl alcohol, polyvinyl acetate, phenolic resin, polyvinylformals, polyacrylic acid or methacrylic acid esters. The combination panels have improved thermal insulation than plain glass, thus saving energy used in heating the greenhouse, and also give improved control of condensation on the panels so that humidity control in the insulated greenhouse is facilitated.

Title: Pulsed laser unit producing linearly polarised light - uses optical feedback path length to determine pulse length
IPC: H01S3/109
Filed: 1980-08-22
Abstract: The length of the pulse of coherent light produced by this laser is determined by the length of time taken by a proportion of the output light to travel along an optical feedback path. The initial stimulating light input is switched into the amplifying medium (2) by a polarising switch or Pockel cell (1). 90% of the resultant light is coupled through a semi-reflecting mirror (4), while the remaining 10% is reflected by two mirrors (5,6) back to the light input (3). Between the two feedback mirrors (5,6) are a half-wavelength plate (7) and an absorbing medium (8). The length of the path is related to the pulse length by the equation t equals c/d, where C is the speed of light. Thus a path length of about 30 cm. will produce a pulse length of 1 nano-second.

Title: Repairing cracked wall by drilling blind bores on crack - and injecting liquid self-hardening agent bonding with wall material
IPC: E04G23/02
Filed: 1980-12-17
Abstract: The arrangement is intended for repairing a cracked wall. Holes of greater diameter than the crack width are drilled in the wall along the crack up to a depth which is a little less than the wall thickness. These bores and the crack with which they connect are then filled under pressure by injecting a liquid self-setting agent which forms a bond with the wall material. The agent may comprise sand, cement, water and a water-soluble plastic, e.g. poly-vinyl acetate. Water or another liquid may be injected first to improve bonding of the subsequently injected agent. Injection may be by hand pump whose outlet diameter equals the diameter of the bores.

Title: Coil wound double walled tubular heat exchange element - has tube in recrystallising plastic extruded around inner tube before winding
IPC: B29C71/00
Filed: 1982-08-12
Abstract: Element comprises an inner tube (2) co-axially contained (and centralised by spacers) within an outer tube (5) consisting of (extruded 4,4a) plastic with strongly recrystallising characteristics, preferably poly-butene. The spacers may consist of internal longitudinal ribs integral with the inner tube (5) wall. The element may be produced by extruding the tube (5) around the inner tube (2), which is preferably in copper or may be in poly-butene or another plastic, followed by winding on a reel (7) with collapsible core before recrystallisation and holding it on this core for lateral removal after recrystallisation. Used for coil-wound double-walled tubular heat exchange element with plastic outer tube. Winding immediately following extrusion is a simple operation as, before re-crystallisation, the plastic is still very flexible. After e.g. one hour, the plastic has set through recrystallisation and the composite tube can be readily removed from the collapsible winding core.
Patent NL-8302731-A (NL)
IPC: H01L29/78
Filed: 1983-08-02
Abstract: The invention relates to an integrated MOS circuit comprising a MOS transistor which is connected as a resistor and which, when current is passed, generates a voltage which is supplied to the sourceigate of a second field effect device. In order to obtain a suitable current adjustment, the two channel widths are chosen so that due to narrow channel effects a difference (though small) in threshold voltage is obtained. The invention is of particular interest for CCD input circuits for generating a small offset voltage required tor supplying FAT-zero.
