Patent NL-6616954-A (NL)
IPC: B29C65/42
Filed: 1966-12-01
Abstract: 1,107,925. Seaming non-metallic sheet material. ST. REGIS PAPER CO. 14 Oct., 1966 [21 Jan., 1966], No. 45965/66. Heading B5K. Two opposed sheet surfaces are continuously bonded together by progressively drawing together at a nip 16 the two surfaces having disposed between them an inflated tubular strand 24 of molten thermoplastic resin which is fed between the sheet surfaces in advance of the nip 16. As shown, two webs 10, 11 or a folded single web of sheet material, e.g. paper, are continuously advanced by pinch rollers 13, 14 defining the nip 16 and covered with resilient material, e.g. rubber. The bonded web is further advanced by rollers or other means (not shown). A roll 17 guides the edge of the web 10 so that the webs 10, 11 converge towards the nip 16 at a small acute angle, e.g. 10-15 degrees. The strand 24 is extruded from an annular channel in a die 18, Fig. 3, this channel being formed between a nozzle 20 and a flange 22 of a conduit 21 which supplies an inert non-flammable gas, e.g. air. The thickness of the strand 24 may be changed by using a different die having a nozzle 20 and/or a flange 22 of different dimensions or by replacing the flange 22 with another flange. The gas pressure is adjustable by a valve 23 so that the strand 24 is inflated to the desired size. Specified thermoplastic resins are polymers of olefins, e.g. ethylene and propylene, vinyl chloride, vinyl acetate and vinylidene chloride. copolymers of these monomers and a blend of these resins. The resins may contain a plasticizer. The invention is applicable to forming the side seams of bags.

Title: Oligomerisation of isobutene
IPC: C07C2/10
Filed: 1970-02-13
Abstract: Isobutene contained in C4 hydrocarbon fractions from which butadiene has been removed, is oligomerised by contacting the gaseous C4 mixture at 100-300 degrees C (esp. 160-190 degrees C) with a catalyst consisting of SnO2 and MoO3 on an inert carrier such as silica. The process is an economical method of recovering isobutene from C4 hydrocarbon fractions obtained e.g. by catalytic cracking and isomerisation of oil fractions. The oligomers produced can be recovered by distillation and there is little tendency for codimerisation of isobutene with n-butenes present.

Title: Centrifugal type liquid pressure regulator for automatic transmission - has two weights with springs linked to valves absorbing and releasing energy
IPC: G05D13/30
Filed: 1973-09-18
Abstract: A hydraulic regulator in an automatic gear transmission system consisting of an element which can rotate around a shaft with a valve and weight unit. There is also a slider with feed opening for the pressurised liquid and an outlet valve. The valve can move outwards due to the action of the centrifugal force forming a connection between inlet and outlet. The pressure in the outlet can increase in three stages to close the outlet valves. There are two weights linked to the respective valves via springs. These springs are used to absorb the energy generated by centrifugal action and to release it according to the gear changes.

IPC: B23K20/00
Filed: 1974-05-21
Abstract: 1502965 Welding by pressure; welding electrical contact PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 16 May 1975 [21 May 1974] 20840/75 Headings B3R and B3A In a method of welding a wire 9 (e.g. gold) to a semi-conductor body 1, an electric spark discharge between an electrode 10 and the end of the wire 9 melts the wire to form a ball 11 below a recess 8 in the welding surface 6 of a welding tool 5, preferably an ultrasonic sonotrode, whereupon the tool 5 presses the ball 11 on to a contact place 2 of the semi-conductor body 1 to produce the weld. The welding tool 5 also produces a weld between the wire 9 and a supply conductor, without the formation of a ball 11 (Fig. 6, not shown). The electric spark discharge may be provided by way of a transformer fed by a discharge capacitor, the discharge time being less than 5 msec. and the energy of the discharge (hence the size of the ball) determined by the capacitor voltage. The recess 8 can either be a groove transverse to the wire 9, which is fed to the welding surface by way of a hole in a separate plate (not shown) or an aperture 7 in the welding tool, or a cone having an apex of 120 degrees. On completion of the weld to the supply conduction the tool remains in its welding position as the wire is snapped by pulling.

Title: Hydraulic demonstration model for money in circulation - price rise is represented by increased level in revolving drum representing money circulating
IPC: G09B19/18
Filed: 1975-05-02
Abstract: Instrument for demonstrating effects as caused by release or decrease in money supplies, and rate of circulation of money, or the number of times than a monetary unit changes hands over a given period, using a rotating drum with a controllable inlet and outlet for a liquid, which can be set in motion to revolve at a controlled speed, and means to determine the liquid level in the drum. The liquid in the drum is taken to represent the money in circulation, with the inlet and outlet control cocks representing the corresponding monetary supply controls. Adjustment of the speed of rotation of the drum changes the circumferential speed of the liquid in the drum, causing a rise in the level at the circumference which represents the increase in prices resulting from the increased rate of circulation of the money. The drum rotates about a vertical shaft, driven by a motor with a continuously variable coupling at a measured rate. Three inlet valves and flow-meters are fitted to three inlet pipes and three similar outlet controls are fitted. The drum is made of transparent material so that the level of liquid at the circumference can be directly read off on a scale. The three inlets represent additional money put into circulation by the government excess of balance of payments and credits granted.

Title: Oil vapour diluent gas mixture preparation for burner - in which diluent gas permits low oil vapour pressure thus lower operating temperatures
IPC: F23K5/02
Filed: 1978-11-22
Abstract: Appts. to burn liquid fuels in a gaseous fuel burner, which includes preparatory appts. for atomisation of liquid fuel oil pref. by a diluent gs. Then heating of the fuel droplets and diluent gas so as to completely vaporise the liquid fuel. If atomisation is by other means, diluent gas is added prior ot vaporisation heating. The resulting oil vapour-diluent gas mixture then goes to a burner which utilises the central orifice of a conventional gas burner. Primary air is induced into the burner tube due to the high velocity of jets of oil vapour-diluent gas. The diluent gas permits low vapour pressure of oil vapour and thus lower operating temperature. For the use of gaseous fuel, the same burner is utilised. The diluent gas can be pref. any noncombutsible and non-oxygen containing gas.

Title: Heat welding two parts of thermoplastic binding string - by heating parts whilst bent just before pressing together side by side
IPC: B65B13/32
Filed: 1980-07-16
Abstract: Laterally heat-welding together two parts (1a,b) of a cord or string contg. thermoplastic material, partic. when tying this string around a parcel or bundle is described. A heating element (4) is moved between the two parts and the parts pressed together (5a,b) behind this element to produce the weld. At least one of the parts is bent just before pressing the parts together and heated whilst bent, after which the parts are pressed together and allowed to cool. Prior to this bending in one direction, the part is pref. bent in the opposite direction (6a,b). Used for securing the ends of thermoplastic binding string by heat-welding when tying up a parcel. The arrangement prevents the heated areas of string, e.g. consisting of twined plastic strips, from twisting before being pressed together which would produce an unsatisfactory weld. It also tends to flatten the cross-section of the string thus exposing a greater surface area to the heating element.
