Abstract: 1,219,516. Seaming. DYNAMIT NOBEL A.G. 19 Dec., 1968 [22 Dec., 1967], No. 60517/68. Heading B5K. Two blocks 1, 2 of foamed resilient synthetic. thermoplastic material are welded in end-to-end relationship by pressing the blocks 1, 2 together, causing a parting means 8 to move between the blocks so as to form a moving space behind the means 8, heating and softening the end faces of blocks in the region of the moving space, and, when the space has moved on, allowing the softened region of the end faces to come into contact and to become welded to each other. In one embodiment, Figs. 1 and 3b, the blocks 1, 2 are clamped by devices 3, 4 on tables 5, 6 which are slid towards each other so that the end faces to be welded are pressed together. A welding device comprising the parting means 8, in the form of a wedge, and an electrically heated wire 9 is forced between the block ends with the wedge 8 leading so that the wire 9 heats the end faces partly by radiation and partly by contact. Preferably, the wedge 8 is coated with a lubricant, e.g. silicone oil. Pairs of supporting rolls 11 may be arranged behind the wedge 8. The wire 9 may be replaced by an electrically heatable rod or tube. In another embodiment, Fig. 4b, the wedge 8 is replaced by a leading roller 12 and following pairs of supporting rollers 12 arranged in wedge form. A supporting column 8a is provided. In a further embodiment, Fig. 5a, the parting means comprises two solid wedge-shaped members 17a, 17b arranged side-by-side with a channel therebetween. A pair of bands 13, 14 pass through the channel and around the members 17a, 17b and each band is attached at one end to a fixed clamp 15, 16 and at the other end to a movable device 20. In use, the parting means is brought into its starting position prior to pressing the blocks 1, 2 together. The device 20 pulls the members 17a, 17b followed by rollers 18 and a heating wire 19 between the blocks 1, 2. The members 17a, 17b may be braked by weights attached to the rear of the apparatus.

Abstract: 1294679 Urethane drying oils MARATHON OIL CO 24 Dec 1969 [25 Feb 1969] 62901/69 Heading C3R [Also in Division B2] Unsaturated urethane drying oils are prepared by reacting (1) a hydroxyl group-containing partial ester of an unsaturated fatty acid with (2) a polycarboxylic acid or an anhydride thereof to provide a hydroxyl group-containing unsaturated polyester which is then reacted with an organic dihalide and a metal cyanate or analogous cyanate (e.g. a pyridinium or tetraalkylammonium cyanate) behaving as a metal cyanate. In examples hydroxyl group-containing partial esters (1) are derived by ester interchange from safflower or linseed oil and pentaerythritol, glycerol or trimethylolpropane, are further converted to hydroxyl groupcontaining unsaturated polyesters by reaction with phthalic, succinic or maleic anhydride, and finally converted to urethanes by reaction with potassium cyanate and either para-xylylene dichloride, meta-xylylene dichloride or 1,4-dichlorobutene-2. The resulting drying oils may be dissolved in xylene or mineral spirits and if desired mixed with cobalt and lead naphthenate driers to form coating solutions. Uses.-For coating stone, steel sheets, wood, plastics, glass, concrete, cinder block aggregates, metal wires and wrought iron.

Title: Filter belt press
IPC: B01D33/00
Filed: 1979-05-30
Abstract: In a filter belt press for straining of water from sludge or precipitated suspensions the sludge is supplied from an inflow trough (2) to an endless upper filter belt (10), from which the partially dried sludge (19) is conveyed to a lower filter belt (17), for pressing between the belts (10, 17) as they pass around a drum (13) and pressing rollers (15), and then the sludge cake is removed from the belts (10, 17) by scrapers.

Title: Method of linking-on elastic yarn
IPC: D04B1/18
Filed: 1979-07-04
Abstract: The present invention relates to linking-on elastic yarn into knitworks in two cylinder circular knitting machines for manufacturing hosiery and similar goods. The knitting process is performed in the following manner: in the first feed, normal yarn is fed to needles distributed e.g. 1:1, and normal loops are formed on all needles. Behind the clearing point of the first feed, the needles are displaced into the closing position. When the formed loops are situated on the needle latches, elastic yarn is lapped into the needles. The needles are further displaced into the closing position and both the elastic yarn and the formed loops get below the needle latches. In the following feed, normal yarn is fed into the needles, which is interlocked with the elastic yarn, so that the latter becomes linked with the knitwork. In this manner, the elastic yarn is not lapped merely as weft threads and cannot be withdrawn from the knitwork upon breakage. <IMAGE>

Title: Aeration propeller and apparatus
IPC: B01F27/71
Filed: 1979-04-10
Abstract: An apparatus (10, 212) for mixing a gas and a liquid is disclosed. The apparatus is comprised of a hollow outer housing (22) and a hollow inner tube (24) received for rotary motion within the outer housing (22). A motor (61) is attached to the outer housing (22) adjacent a first end thereof and is drivingly coupled to a first end of the inner tube (24). The inner tube (24) has a support tube (214) which extends beyond the second end of the outer housing (22). Propeller blades (216) are attached to the support tube (214) for rotation therewith. An inlet (82) is formed in the inner tube (24) for admitting a gas to the hollow interior of the inner tube (24). The support tube (214) has a diffusion section (222) that extends below the propeller blades (216). The propeller mechanism (210), which includes the support tube (214) and the blades (216), is designed to increase the oxygen transfer efficiency of the apparatus (10, 212) over that provided by a standard marine propeller (48).

Title: Ice warning indicator
IPC: G01N27/04
Filed: 1980-01-09
Abstract: The formation of ice on the surface of an embedded device 10 is detected by the rise in resistance between electrodes 12 and 13 detected by 26. The electrode 12 is cooled by the Peltier effect in response to current pulses from an amplifier 23 applied to a thermo- electric cooler 15. Therefore, incipient icing will lead to a detected rise in resistance regardless of the freezing point of the moisture on the ground. The cooling current pulses preferably alternate with heating pulses so that there is no long term disturbance of the heat balance at the device. <IMAGE>
Patent GB-2072918-A (GB)
Title: Tape recorder drive
IPC: G11B15/10
Filed: 1980-03-24
Abstract: A tape recorder uses power derived from a capstan flywheel 12 to move parts to establish a desired mode of operation. When an element 39 is moved to the right on energisation of an electromagnet 43 (or purely mechanically), element 39 disengages from a stop 37a (Fig. 5) in the inner wall of a groove 35 of a part- toothed gear 31 and engages the groove onto wall, whereby a spring 57 is effective via lever 53, roller 56 and cam 51 to partly rotate gear 31 so its toothed part 31a meshes with rotating gear 30 which thereby rotates gear 31 and thus via cam 51, lever 53 and spring 57 shifts a head and pinch roller plate 18 to the operative position, gear 31 being rotated by gear 30 until non-toothed part 31b of gear 31 face gear 30 and element 39 engages a stop 37b (Fig. 5) to lock gear 31. Movement of plate 18 acts via spring 28 to pivot arm 9 to engage motor-driven idler 7 with take-up reel drive hub 6 (Fig. 1). When the electromagnet 43 is de-energised, element 39 is spring-returned to the left thus unlocking gear 31 which, being out of mesh with gear 30, is rotated via spring 57, and members 53, 56, 51, 50 that cam 51 moves lever 53 to allow return of head plate 18 by spring 26 (Fig. 1), the final part of the return being braked by toothed part 31c meshing with gear 30 and gear 31 stopping with non-toothed part 31d facing gear 30 and element 39 engaging stop 37a. A similar arrangement of an electromagnet 44, movable locking element 40, part- toothed gear 32, cam 52, follower 58 and lever 54 is effective for capstan- powered movement of arm 9 to engage idler 63 between idler 7 and supply reel drive hub 5 for rewind, with spring return of arm 9 and final braking thereof by gears 30, 32. A further electromagnet, part-toothed gear, etc. (not shown) may be provided to establish fast forward in a similar manner. <IMAGE>

Filed: 1980-04-09
Abstract: A four shaft eccentric mass vibration exciter 3 for vibration of the trough 1 of a vibratory feeder is driven through a gear-box by a motor 8 connected to one gear-box shaft. This gear-box shaft is provided with a helical gear 13 and is connected to drive one pair of shafts 4 of the exciter. The other pair of shafts 5 of the exciter is driven by a second gear- box shaft which is also provided with a helical gear 16.
