Abstract: 849,270. Tensioning driving chains. HAHN, O., and HAHN, E., [trading as INDEXWERKE KOMMANDIT - GESELLSCHAFT HAHN & TESSKY]. Feb. 13, 1957 [March 6, 1956], No. 4869/57. Class 80 (1). In a chain-tensioning device, particularly for automatic lathes, wherein a chain 20 is tensioned by a wheel 21 carried by a spring-loaded bolt 50 slidable in a sleeve 30 adjustably secured in a fixed rocket 22, the bolt 50 has at its rear end an indicator pin 51 which at normal chain tension projects through a cap 32 on the sleeve 30. Any slackening of the chain, resulting in a movement of the bolt 50 under the action of its spring 34, may thus be readily observed and be compensated by adjustment of the sleeve 30 in the socket 22 to restore the normal spring loading. The projection of the indicator pin may, as shown, be only slight and/or the pin may be provided with a scale. The bolt 50 is held against rotation by a stop-pin 42 slidable in slits in the sleeve 30. The sleeve 30 is adjustably clamped in the socket 22 by a bolt 26 and is held against rotation by a key 45. An impactabsorbing spring 54 is housed in a bore in the sleeve 30 between the cap 32 and a plate 55, the latter being contacted by the end of the bolt 50 when an impact on the wheel 21 occurs. In a modification the spring 54 is omitted. It is stated that an acoustic or optical indicating device may be operated by the movement of the bolt 50.

Title: Electrophotosensitive coating material and electrophotographic image carriers
IPC: G03G5/05
Filed: 1958-02-17
Abstract: 888,371. Electrophotographic plates. HARRIS - INTERTYPE CORPORATION. Feb. 17, 1958 [Feb. 15, 1957 (2)], No. 5106/58. Class 37. [Also in Group IV (a)] An electrophotographic plate is formed by applying a hydrophilic photo-conductor film to a base member from a fine dispersion of solid photo-conductive material in an acid, alkaline or neutral aqueous solution of a synthetic resinous film-forming material. Suitable photoconductive materials are those having very high dark resistivity and a surface photoconductivity of at least 10<SP>-9</SP> ohm<SP>-1</SP>/square/ watt/cm.<SP>2</SP> for a wavelength in the range 3800-7000, certain samples of white and pink zinc oxide, titanium dioxide, zinc sulphide, cadmium sulphide and zinc selenide being examples of such materials. Suitable filmforming materials which may be soluble only in neutral or alkaline solutions are selected from the following classes of material: polyacrylic and polymethacrylic acid and ester resins and amides, polyvinyl compounds comprising ester, hydroxyl or carboxyl groups, polymethacrylic acid vinyl acetate copolymers and polyvinyl methyl ether maleic anhydride copolymers, partially esterified or partially amide. Where it is necessary to add alkali to the water to dissolve the film-forming material volatile organic bases such as monoethylamine or aqueous ammonium hydroxide, which are removed in a subsequent drying process are used. The ratio by weight of photo-conductor to filmforming material in the dispersion should lie in the range 2 to 1 to 25 to 1, the optimum ratio depending on the type of light to which the plate is exposed. The dispersion is applied to a paper or metal base which is subsequently heat treated at 150 C. for about 30 minutes to remove the moisture. Specification 888,372 is referred to.

Abstract: 1531325 Attaching fastenings TEXTRON INC 10 Feb 1976 05147/76 Heading A3H [Also in Division B4] Apparatus for attaching components having two mating elements 10, 12 to articles 14 by bringing the elements together from respective stations 16, 18 vertically aligned above and below the article, so as to engage one another through the article, comprises hoppers 24, 26, chutes 28, 34 and slide paths 32, 38 whereby the elements are sequentially delivered to their respective stations, and pneumatically operated rams 80, 82 for pressing the elements together. A slide bar 66 in the upper slide path 38 advances elements 12 therealong to the station 18 where they are held between resilient members 146, 148, Fig. 5, mounted slidably on the ram 82; when the ram is lowered the members 146, 148 are arrested by the article 14 and as the shaped end 156 of the ram continues to descend and engage the top of the element 12 the members 146, 148 are deflected outwardly. A reciprocating bar 48 has projections 60, 62 extending upwardly into the lower slide path, Fig. 4; when the bar advances the projection 60 pushes an element 10 along a tortuous, prong-aligning portion of the slide path to a mid-way position where it is resiliently held between members 136, 138; simultaneously a further element 10 is pushed out of engagement with these members and delivered to the station 16 by the projection 62. As the bar 48 is retracted it is deflected downwardly so the projections avoid the elements 10. A system of pneumatic cylinders 72, 56 and respective levers 84, 50 arrange for the bars 66, 48 to be advanced as the rams are retracted, and retracted as the rams are brought together. An indicator 94 mounted on a forward extention of the slide bar 66 directs a beam of light vertically downwardly from the station 18 when the bar 48 is fully advanced to indicate the precise position on the article 14 where the elements will be attached.

Title: Process for directly reducing materials containing iron oxide in a rotary kiln
Inventor: HEITMANN GUNTER
IPC: C21B13/08
Filed: 1969-01-30
Abstract: 1,203,532. Reducing iron ore. METALLGESELLSCHAFT A.G. Jan. 30, 1969 [Feb. 8, 1968], No.5254/69. Heading C7D. Iron oxide is reduced by means of a solid carbonaceous reducing agent in a rotary kiln in which the flows of charge and gas are co-current, the heat of the exhaust gases being used at least in part to heat and/or dry the sponge iron which is separated from the kiln discharge after the latter has been cooled, preferably by immersion in or spraying with water. The reducing agent may be coal of high volatile content and a particle size of less than 4 mm., and may be blown into the charging end of the kiln in a stream of oxygen-containing gases. After use for heating and/or drying the sponge the gases may be used, possibly after combustion at the point of use, to pre-heat or dry the kiln charge. In other applications the gases may be used to harden pellets formed from the iron fines produced, or for steam raising. In a preferred embodiment of the invention, two kilns are used having their flow directions in opposition so that a part of the hot exhaust gases from each may be conveniently used to heat the charge and/or combustion air of the other.

The ladder is extended or collapsed by a vertically-sliding rod 8 carrying brackets 11 to which the links are pivoted. This rod extends through a socket 9 secured to the top platform and carries pins 14, 15, which, by engaging with the upper and lower edges of the socket, hold the ladder in the extended position, the upper pin 14 being removable. Stops 21 on the rod 8 limit the inward movements of the ladder portions, while light chains 20 extending between the ladder portions and the side supports limit the extent of opening. The rod 8 carries, at its upper end, a tray 16 to which are hinged a pair of flaps 18 which are adapted to be held in a horizontal operative position by turn-buttons 19. The tray also carries hooks 17 from which articles may be suspended. In a modification, the central rod 8 is dispensed with and the links 10 are connected to a central member such as a ring or rectangular block.

Abstract: 1,038,211. Electric selective signalling systems. ESCHER WYSS A.G. Feb. 8, 1963 [Feb. 8, 1962], No. 5345/63. Heading G4H. In a torsion measuring system the displacement of one end of a shaft with respect to the other end is measured by an arrangement comprising two toothed wheels d1, d2. Fig. 1, one of which has one more tooth than the other, associated sensing heads g1, g2 and a counter arranged to count the teeth on the wheel d1 that pass the sensing head g1 between the instant that a reference tooth labelled 0 passes the head g1 and the instant that a pair of teeth are sensed simultaneously by the two heads g1 and g2, this being detected by a thryatron k. By this means a small relative displacement #, Fig. 2, of the two ends of the shaft is magnified to a period #, thereby permitting # to be measured with a high degree of accuracy.
