Title: Tree trunk dia. measuring appts. - has complementary matrices of optical fibres to create collimated light field
Inventor: HAMMAR MARTIN
IPC: G01B11/24
Filed: 1977-07-08
Abstract: A trunk (41) of which the diameter is to be measured is passed through a measuring station (40). The trunk is axially located by a V-block guides (42, 43). The measuring station has side members with a vertical cover (44) which encloses a light probe matrix which includes a number of optical fibres in a mounting frame (45). In a typical device there may be several hundred fibres. A similar mounting frame (48) carries optical fibres on the other side of the measuring device. The fibres, which are of conventional construction, have a central core of high refractive index and a coating of lower refractive index. The may be separated by a spacing of about 1mm and arranged in three vertical rows offset from one another. Collimated light is transmitted from one array to the other and detection of the shadow thrown by the trunk, gives an indication of its diameter.

Title: Advancing pit prop and mine roof covering system - uses lubricated zigzag folded plastics sheets, successively overlapped to guard against roof falls
Inventor: LEWER HANS
IPC: E21D11/15
Filed: 1977-09-08
Abstract: An advancing pit prop system includes application of plastics, sheets to the roof as a protection against falls during operation. These sheets may be of polyethylene, and are folded in a zig-zag manner to form a bundle between 0.6 and 1 m thick. Each sheet is inserted between the top parts of the pit props so that it is overlapped with the free edge of a previously applied sheet. The pit props are then advanced, trapping the sheet, so that it is held in position. Lubricant can be applied between the sheets. Their thickness can be between 0.2 and 0.5 mm, their tear resistance is at least 15N/mm2 and elongation at least 4m/m or 400%. Alternatively, instead of a single sheet, two or three sheets, each 0.075 to 0.3 mm may be used on top of each other. A hygroscopic salt layer can be retained by the sheet.

OR is an oxyalkylene gp. of the formula -O-CHR4-(CH2)m-CH2-; m = 0, 1, 2, 3 or 4; R4 is H or if m = 0, can also be 1-4C alkyl, chloromethyl or phenyl) is effected by reacting (III) with (II) of the formula: R4CH-(CH2)m-CH2 in the presence of Lewis acids, as in DT2640505. The novel feature is thar R2 is the same as R1. (I) have useful properties, esp. wrt their hydrophilic-hydrophobic character. They are miscible with many organic solvents and can be readily soluble in water, depending on the oxyalkylene and terminal gps., without contg. typical hydrophilic functional gps. with active H, e.g. OH or amino gps. They can be used for selective absorption and extn., as inert solvent aids and in hydraulic fluids. Their Lewis base property makes them useful as absorbent for acidic gases, esp. for the purificn. of refinery and petroleum gases. As solvent aids, they are useful for lacquers and in chemical reactions, e.g. Grignard reactions.

Title: Optical smoke detector inlet screen - consists of wire mesh extending between offset ports on outside and inside walls of dark chamber to bar insects
Inventor: STEELE DONALD FRANCIS
IPC: G08B17/107
Filed: 1978-05-30
Abstract: An optical smoke detector has a housing which forms a dark chamber into which light is directed on a path viewed by a photocell. Light scattered from the path by smoke causes the cell to trigger an alarm. The housing includes an interior wall around the dark chamber and an exterior wall exposed to ambient light. A wire mesh extending between offset ports in the exterior and interior walls screens insects from the chamber and obstructs light from passing directly to the interior part. A typical mesh screen is of dull black coated aluminum wire cloth with wire 0.011 inch in diameter and 18 openings per square inch.

The treated fabric is dried and printed with transferable dyestuffs or optical brighteners and then opt. after-treated with a crosslinking agent (III). The process is specified for printing cellulose and cellulose/polyester textiles. It is esp. useful with cotton/polyester textiles and can also be used with mixed textiles of cellulose and another synthetic fibre, e.g. polyacrylonitrile or polyamide. It allows cellulose to be dyed or printed with transferable, esp. sublimable dyestuffs having an affinity for synthetic (polyester) fibres. Good and level dyeing of both types of fibre is obtd., which withstands washing, and no discolouration of the white ground of prints occurs. There is no disagreeable odour associated with the printing process and no detrimental effect on the finish or feel of the fabric. In an example, a polyester/cotton fabric was impregnated with a liquor contg. 50 g./l. polyester (mol. wt. 2075; prepd. from butane 1,4-diol and adipic acid in 6:5 molar ratio) and 100 g./l. polyethylene glycol (mol. wt. 400) and dried before transfer printing. Good and uniform printing of both fibres was obtd. throughout.

Title: Microwave defroster for frozen food - defrosts within minutes by radiating microwaves directly onto food and by cooling sides
Inventor: FRITZ KARL DR
IPC: A47J39/00
Filed: 1979-01-12
Abstract: The microwave defroster radiates the main part of the energy directly onto the food whilst preventing the sides warming. Screens are located on the outside of the food that reduce the field amplitude in this region. The sensitive outer parts are colled by forced radiation and medium cooling such that they retain their mechanical strength. The entire process may occur in a refrigerator. Helical antennae are used for radiating and have a turns length of one wavelength. The food is placed on a rotary table. The defroster is particularly for cakes and tarts.

Title: Valve mechanism for multicylinder IC engine - has hydraulic system to disconnect tappet when cylinder is switched-off at part load
Inventor: BRUDER WERNER DIPL ING
IPC: F01L13/00
Filed: 1979-07-04
Abstract: The tappet has a cap fitting over a dowel. The cap is depressed by an overhead cam and engages the dowel through saw tooth gears on the inside of the cap and outside of the dowel. Oil can be admitted to a chamber between the cap and dowel and raises the cap from the dowel. As it does so profiled plates cause relative rotation of the cap and dowel. When the pressure is released further plates cause further rotation. The rotation disengages the saw teeth and stops further operation of the valve. The disengaging action can take place over several engine strokes.
