Title: Constant speed and tension beam let:off motion - adjusts to tension via infinitely variable pulleys and gears
IPC: D03D49/10
Filed: 1976-12-10
Abstract: An arrangement for maintaining the unwinding of the warp threads from the beam in a loom at constant speed and tension, includes a train of intermeshing and easily interchanged gear wheels together with a pair of split, "V"-belt pulleys forming a variable transmission. The firt variable speed pulley is driven from the loom main shaft, and the variation of the transmission ratio of the belt pulleys is effected bya system of connecting rods and levers responding to the tension on the warp threads. The gear train is formed by two pairs of wheels linked by a worm to the beam. One of the gears is keyed on the worm shaft, and the worm engages with a worm wheel attached coaxially to a gear wheel engaging with another on the beam shaft. The linkage responding to the warp yarn tension includes a rocker with a cylinder at one end over which the warp ends run, and a vertical connecting rod at the other which joins a horizontal lever with a counterweight. This is connected to the levers altering the widths of the variable speed "V"-belt pulleys. The arrangement improves the working conditions of the variable speed belt transmission so that it works accurately and reliably at very low speeds. The variable speeds pulleys are driven continuously by the loom main shaft turning at the same high speed so that they are not dependent upon the transmission through a train of gears. The speed of the beam cna thus be accurately adjusted.

Title: Multi work-piece clamping mechanism - secures to rotary mandrels on periphery of slewing table with locking devices
IPC: B23Q39/04
Filed: 1977-03-18
Abstract: The mechanism clamps workpieces in order to carry out operations with them in different positions turned through 360 deg. or a multiple of them about an axis. The workpieces are clamped coaxially to the axes of rotation on the outer ends of a number of rotary mandrels (14), spaced along the periphery of a slewing table (13). The other ends of the mandrels have coupling members (17), engaging for at least part of the table periphery with one or more other coupling members (8, 8) fixed in relation to the vertical table axis. Thus as the table slews through a set angle, the coupled mandrels are correspondingly turned into the corresponding machining positions. All machining stations are accommodated within the 360 deg. through which the table slews, and the various machining positions of the workpieces on the mandrels are determined by locking devices (22) at the stations, actuated by a common pressure mechanism (23, 35), and engaging with complementary devices on the mandrels.

Title: Shoe sole and upper fitting process - by fixing inner sole and upper on last, introducing dome membrane and applying pressure in cage chamber and vacuum in last chamber
IPC: A43D13/00
Filed: 1977-12-28
Abstract: The method is for the formation of the upper part shoe sole, and comprises the fixture of the inner sole and the upper on a last, (22) retained on a fixed under support. A dome-shaped membrane (14) is fixed into position which forms a wall of a closed cage (4), and is stretched over the last with the upper. A high vacuum is then applied in the last chamber, and an excess pressure is applied in the cage chamber. After removal of vacuum and pressure, the upper is stretched over the last by application of torsional forces by the membrane on the upper. At least the top surface of the membrane (14) in contact with the upper on the last is rough.

Patent PT-79767-A (PT)
IPC: A61F13/20
Filed: 1984-12-28
Abstract: The invention relates to a tampon (10), to the essentially cylindrical circumferential surface of which a liquid-permeable, thermoplastic material is fastened, with the application of pressure and heat. The dome-like constriction (10b) at the introduction end (10a) and the withdrawal end (10c) of the tampon (10) remain free of the liquid-permeable, thermoplastic material. The fastening of the liquid-permeable material to the outer surface of the absorbent material of the tampon (10), which consists of a nonwoven ribbon section rolled up on itself and pressed radially to give the final form of the tampon (10), guarantees that the high absorbency of the nonwoven fibre material, based on capillary action, continues through the liquid-permeable, thermoplastic material onto its outside. In addition, the liquid-permeable material offers protection against fibres becoming detached and makes it easier to introduce the tampon into and remove it from the body cavity.

Title: This invention relates to the treatment of liquids especially oxygen enrichment of water which is utilized for aqui culture
IPC: C02F1/72
Filed: 1987-02-10
Abstract: Method and installation for the treatment of liquids, especially oxygen enrichment of water is used for aqua culture purposes such as the breeding of fish. Thus, it is an object to provide a method where gas bubbles in the water reservoir are avoided and where one freely can treat fresh water and/or recirculated water for optimal temperature control and/or water renewal. The water flow is mixed with a flow of pure oxygen gas which is supplied from an oxygen tank 4 with liquid oxygen. The oxygen is led through an evaporator 16 into a flow system which forms a recirculating circuit, with pipeline, and oxygen enrichment means or reactor unit 2 where water and oxygen are mixed to form a turbulent, foaming gas/liquid flow. The mixture is subsequently led into a gas/liquid separator 3 where gas and liqid are separated. The gas mixture from the separator which now in addition to oxygen also will contain other contaminants like nitrogen and carbon dioxide, is recirculated by means of a compressor 6. To prevent the building up of great amounts of nitrogen and other contaminants, there is provided a de-aeration means in the form of a bleed 10 or in the form of a special separation unit.
