Title: Lubricating oil compositions containing detergent-dispersant additives
IPC: C10M141/10
Filed: 1979-06-15
Abstract: Improved detergency is imparted to a lubricating oil by incorporating therein a conventional dispersant or detergent, which can be an alkenyl monosuccinimide, an ester of a hydrocarbon-substituted succinic acid, a monohydroxyalkyl hydrocarbyl thiophosphonate or a high-molecular weight Mannich base or borated complex thereof, in combination with a substantially saturated aliphatic sulfonate of a Group II metal capable of forming with the sulfonic acid moiety a salt which can function as a detergent in a lubricating oil. The metal will preferably be calcium or magnesium. A concentrate from which a lubricating oil composition containing the above detergent-dispersant and the above aliphatic sulfonate additives can be formed comprises a lubricating oil and about ten times the concentration of the additives that would be required in the final composition. Calcium, sodium and magnesium polyisobutenyl sulfonates are prepared in the examples.

Title: Dial illuminator for analog timepiece
IPC: G04B19/30
Filed: 1980-06-27
Abstract: A dial illuminator for an analog wristwatch or clock comprises a substantially transparent, light- transmitting annulus 20 disposed around the periphery of the dial 10 between the dial and crystal 6, and a point light source 22 (such as a miniature incandescent bulb) disposed in a recess 20e in the annulus. The annulus 20 is provided with a roughened, light-diffusing inner peripheral surface 20a which surrounds the dial and watch hands 11 to 13 and as shown also with a light-reflecting outer peripheral surface 20b and light-reflecting top and bottom surfaces 20c, 20d so that light from the source 22 is reflected and scattered around the annulus and diffused through the inner peripheral wall 20a uniformly over the dial and hands for essentially 360 DEG  illumination thereof. A reflector ring may optionally be placed around the dial periphery to define an annular chamber into which the annulus 20 is inserted with the reflector ring functioning to minimize leakage of light from the other walls of the annulus to thereby enhance dial illumination. The reflector ring may take other forms including a reflective coating deposited on the outer peripheral and top surfaces of the light-transmitting annulus or on portions of the crystal which overlie these annulus surfaces. <IMAGE>

Title: Methods of a storing/transporting fish to preserve freshness
IPC: A23B4/06
Filed: 1980-12-02
Abstract: The method for extending the period of freshness of fish, particularly pelagic fish and especially so-called "blue fish", such as anchovies, sardines, herrings, pilchards, mackerels, etc., comprises placing the freshly caught fish in tanks or ponds on a fishing vessel which contain a liquid, e.g. sea water, that is maintained at a controlled temperature, preferably about 0 DEG C., so that the liquid will envelop each fish and avoid any squeezing pressure thereon. Similar tanks can achieve the same results in the storage and transportation of fish ashore.

Title: Boom element for a flexible floating barrier usable in shallow or tidal waters and a method of containing pollutants in such waters
IPC: E02B15/06
Filed: 1981-01-23
Abstract: A flexible floating barrier or boom for containing the spread of oil and other pollutants floating in shallow tidal waters comprises a flexible buoyancy tube (1) and two juxtaposed flexible ballast tubes (2). The buoyancy tube is disposed above and intermediate the ballast tubes and is joined in contiguous relation with the latter. The buoyancy tube may be inflated with air or plastics foam material whilst the ballast tubes are filled with water so that the boom floats with the buoyancy tube projecting above the surface of the water and the ballast tubes below the surface. A weighted skirt (4) depends from the buoyancy tube between and below the ballast tubes. In tidal waters, when the tide ebbs, the boom settles onto the sea or river bed in an erect position and the ballast tubes seal against the bed so that polluted water may be contained behind the boom. <IMAGE>

Patent GB-2097098-A (GB)
Title: Making spring metal piston rings
IPC: B23P15/06
Filed: 1981-04-22
Abstract: A method of manufacture of a piston ring 10, includes making a ring blank having an outer diameter which is greater, and an inner diameter which is less than that of the finished ring. The holes are drilled in the blank, and two substantially parallel pins are extended from retracted positions (in which they are aligned with the axes of the holes but out of engagement with the ring blank) to extended positions in which they engage in the holes without stressing the blank. A gap is cut in the blank, either before or after the drilling step, to afford two free ends, such that each hole is adjacent an end. The spacing of the pins is reduced to hold the ring blank in an at least partly closed position. One or more of said blanks are clamped in this position and their inner and outer peripheries are machined to be circular. <IMAGE>

Both of the flaps 12a, 12b have spikes 54, 56 for use in trapping a web-like workpiece 48. Any parts of the buckle 10 which touch, such as free ends of the spikes 56 located in complementary apertures 52, can be fixed together by ultrasonic welding, heat sealing or adhesive. <IMAGE>
Patent GB-2083442-A (GB)
Title: Labelling frozen food packs
IPC: B65C9/22
Filed: 1981-09-11
Abstract: A labelling gun for applying labels to frozen food packs comprises transfer means (4) for feeding labels (13) past a printing head (5) to an outlet (8) where a label is peeled from a backing paper strip, and a plasticiser applicator (10) positioned adjacent the outlet (8) so as to be wiped by part of the adhesive surface of each label (13) as it is dispensed. The applicator (10) comprises a plasticiser reservoir (12), and an absorbent pad with a projecting tip (10), the location of the pad and tip being adjustable. No plasticiser is applied to the leading edge of the label in order to assist initial adhesion of the label to the food pack. The adhesive is a rubber based adhesive and the plasticiser is a vegetable oil, a mineral oil, or a high boiling point ester. The label develops its adhesion to the food pack as the plasticiser penetrates the adhesive over 6-12 hours, the plasticiser ensuring that the adhesive maintains its tackiness at very low temperatures and thus labels do not fall off. <IMAGE>
