Patent GB-545436-A (GB)
Abstract: 545,436. Vibration-dampers. GENERAL MOTORS CORPORATION. Nov. 27, 1940, No. 16979. Convention date, Dec. 7, 1939. [Class 108 (iii)] [Also in Group XXXVI] The movement of an ammeter is clamped by a plurality of inertia members loosely mounted on the shaft. Secured to the shaft 44 are spacers 58, 60, 62 having rounded faces. Between the spacers 58, 60 is an inertia member 66 loosely mounted on the shaft 44. The spacer 60 has an extension 75 on which is loosely mounted a second inertia member 68. The members 66, 68 are of the shape shown in Fig. 4 comprising a ring having a diametral piece 70 with an enlarged central part 72. Owing to the difference in diameter between the shaft 44 and the extension 75 the frictional movement on the member 68 is greater than that on the member 66 and these members will not move in unison. Fluctuations in the motion of the shaft are thereby damped out.

Abstract: 1,198,877. Cross-linked olefin-vinyl ester copolymers. LEUNA-WERKE " WALTER ULBRICHT " VEB. 18 Nov., 1968, No. 54611/68. Heading C3P. Copolymers of an olefin and a vinyl ester are cross-linked by mixing and heating with an alkali metal alcoholate at 60-250‹ C. The preferred cross-linking agent is a methanolic solution of sodium methylate. The copolymer may be in admixture with an olefin homopolymer and the copolymer of this mixture may be cross-linked. The copolymer may be crosslinked first with a peroxide and subsequently or simultaneously with the alcoholate. A filler, such as glass fibres, may be admixed with the copolymer prior to cross linking. In the examples, a copolymer of ethylene and vinyl acetate, stabilized with a phenolic antioxidant, is cross linked by heating with a methanolic solution of sodium methylate, or with sodium palmitylate, dicumyl peroxide and potassium methylate or lithium octylate. In further examples, a mixture of an ethylene homopolymer and an ethylene-vinyl acetate copolymer are cross linked by first heating with dicumyl peroxide and then heating with either a methanolic solution of sodium methylate or sodium palmitylate.

Abstract: 1,259,837. Printed circuit boards. BOEING CO. 18 Nov., 1968, No. 54626/68. Heading B5N. [Also in Divisions B6 and H1] Printed circuit boards (see Divisions B6 and H1) are incorporated into a sandwich construction. As shown in Fig. 14 the sandwich consists of a printed core 34 of kraft pulp material, an overlay 36 having holes 38 registering with the pads 40 in the printed circuitry and another overlay 42 which has smaller holes 44 that align with the pads 40 and the holes 38. The smaller holes 44 provide access for the component leads and the larger holes 38 for soldering to the pads 40. In assembling the layers, core 34 is compressed and inserted between two paper, wax or plastics sheets suitably punched and each coated on one side with adhesive 46. The sandwich is then bonded together in a press and subjected to a further punch operation in which punch holes 44 are extended through core 34 and pads 40. Two or more of the sandwiches may be interconnected in a multilayer assembly (Fig. 17, not shown) using solder tubelets which provide a capillary guide in each hole 44 for a pressed solder pin. In another modification two or more core layers are bonded between a layer of outer protective layers with component lead openings of differing diameters to expose circular portions of the pads from one core layer to the next.

Title: Apparatus for feeding dissimilarly sized particles into a shaft furnace
IPC: F27B1/00
Filed: 1974-12-18
Abstract: 1491519 Feeding dissimilarly sized particles into a shaft furnace MIDREX CORP 18 Dec 1974 [26 Dec 1973] 54699/74 Heading F4B Iron ore in the form of pellets together with fines is fed into a shaft furnace 10 through a proportionating hopper 41 and tubes 58, the lower ends of the tubes 58 being nearer the furnace's side wall than its vertical axis 60. Cones 62 at the tube ends cause the pellets to roll outwardly and the fines to pass vertically downwardly from the cones' edges. Thereby, the fines form an annular array of columns 66. The ore passes downwardly through the furnace against a current of reducing gases (H 2  and CO) which enter and leave respectively at 31 and 39. From the bottom of the furnace, the reduced ore passes through a cooler 20 with inert cooling gas passing therethrough from a source 26. The ore feeding apparatus comprises an oscillating fines distributor 47 which ensures that, within a bin 44, the fines are uniformly dispersed between the pellets. If one of the tubes 58 becomes blocked, the temperature of the material within the tube rises and this is sensed by a thermocouple (70), Fig. 2 (not shown). A signal from the thermocouple automatically causes water to flow from a pipe 80 and through the tubes 58 to unblock them. The pipe 80 may alternatively be in the bin 44. The water pipe could be operated at periodic intervals independently of the thermocouple to periodically wash the tubes 58.

Filed: 1967-12-01
Abstract: 1,199,427. Making chains; broaching; welding by pressure. BECKER-PRUNTE G.m.b.H. 1 Dec., 1967 [5 Dec., 1966], No. 54869/67. Headings B3A, B3L and B3R. A machine for welding a chain of connected links comprises means for simultaneously operating welding and flash-removing means which are arranged respectively at two separate stations along the feed path of the chain, and first and second means for positioning and gripping two links aligned with a first plane, respectively at welding and flash-removing positions with slack between these two links, welding taking place preferably at a position to one side of a second plane mutually perpendicular to and intersecting, along the axis of movement of the chain, the first plane. Operation.-The chain is fed in steps equal to the pitch, two passes being necessary. In the first pass links 2, 4, 6 &c. aligned in a horizontal plane are welded, and in the second pass links 3, 5 &c. are welded. In each pass the links not being welded are aligned (as shown) in a vertical plane. The link 4 which is to have weld flash removed is positioned and gripped at the flash-removing station by a gripper 22 having a shaped link-engaging portion 23 (Fig. 6, not shown) which engages the limb of the link opposite to that in which the weld was made. When this link is gripped, jaws 7, 8 which define a link-engaging pocket at the welding station, position and grip the link 2 to be welded, the welding position being lower than the flash-removing position so that the link 3 lies slack at an angle. The jaw 8, slidably movable towards jaw 7, causes the split limb of the link to be pinched before welding. In the welding position (Fig. 4) the link is contacted by removable fixed electrode tips 15, 16 and movable electrode tips 17, 18. As welding of link 2 proceeds, e.g. by flash-butt welding, the flash is removed from link 4 by two knives 40, 41, the welding control mechanism and flashremoving control mechanism being simultaneously operated from a central control. When welding and flash removal are completed a finger 51 lifts link 2 out of the welding position and the chain moves forward to present link 2 at the flash-removal station and link 6 at the welding station. Modifications of the positioning and gripping means of the flash-removing station are described (Figs. 12-14, not shown). Electrodes 17, 18 and knives 40, 41 may be operated by fluid cylinders.
