Patent GB-996521-A (GB)
Title: Improvements in or relating to electric-switch control mechanism
IPC: H01H21/34
Filed: 1962-03-30
Abstract: 996,521. Cam-operated switches; momentary-contact switches; retractive switches. LA TELEMECANIQUE ELECTRIQUE. March 30, 1962 [April 5, 1961], No. 12439/62. Heading H2B. The on/off conditions of a limit switch actuated by a cam 30 upon angular movement of a shaft 11 can be easily reversed with respect to the direction of movement of the shaft by rotating the shaft beyond its normal angular limit after temporary release of the limiting means. The cam 30 is fixed on shaft 11 which has an arm 13 secured thereon by screw 41, and pins 32, 40 on cam 30 co-operate with lugs inside casing 10 (Fig 3, not shown) to restrict the movement to a little under 180 degrees. The shaft is spring-loaded to the right by spring 19 acting on a cam sleeve 17 having lugs 17a slidable in grooves 10a, 10b in casing 10. Cam 17 also has V-shaped recesses 33a, 33b which co-operate with V- shaped ridges 31a, 31b on cam 30 to urge the cam 30 (and therefore shaft 11 and arm 13) to a central neutral position. Movement of arm 13 in one direction causes cam 30 to depress ball 7 and actuator 6 of microswitch 1 while movement in the other direction does not operate the switch. Cam 30 is symmetrical about a horizontal diameter such that if the shaft 11 is moved axially to the left against spring 19 and then rotated to move pins 32, 40 past the co-operating stops in casing 10 and then allowed to return to the right, the profile of cam 30 which co-operates with ball 7 is reversed with respect to the previous condition and the switch is operated by movement in the opposite sense. The arm 13 would have to be released and reset 180 degrees displaced after such adjustment. Normally movement of the shaft 11 to the left causes arm 13 to abut a sleeve 12 before pins 32, 40 are clear of their co-operating lugs and thus inadvertent adjustment of the active cam profile is prevented. The device may have two stable end positions instead of a central neutral position by providing cam 17 with four V-shaped recesses in place of the two 33a, 33b. The cam 30 may have other profiles than that shown, for example it might provide momentary actuation of switch 1 by rotation of the shaft in one direction. Specification 906,990 is referred to.

Abstract: 134,176. Slight, E., and Lacy, A. D. Oct. 21, 1918. Proofing. - In apparatus for impregnating articles of pulp or strawboard with waterproofing- material, such as that described in Specification 14246/12, one heating-appliance is employed for heating the impregnating or drying chamber, instead of several. As shown in Fig. 1, the combustion products from the furnace 9 are led into the hollow draining-trough 8, and thence by means of uptakes 11, 12 into the drying-chamber 7, along which the articles, which have been previously dipped in the heated bath 1 of waterproofing- material, are traversed by the conveyer 17. The conveyer is constructed of sheet-metal slats 30, as shown in Fig. 4, the edges of which are bent into tubular shape to accommodate wire links 31 formed with a short end 32. When the length of the conveyer requires adjustment, the slats 30 may be readily disconnected by straightening the short end 32 and sliding out the link. Before dipping in the bath 1 of waterproofing-material, the articles may be submitted to a preliminary partial impregnation with casein or a compound thereof, as described in Specification 134,010.

It is formed in a direct spinning process by stretch - breaking and drafting continuous filaments having a break elongation of less than 70% between input rolls 9, 10 and delivery rolls 11, 12 the delivery rolls being situated 65 to 130cm from the input rolls and rotating at a circumferential speed of 5 to 100 times that of the input rolls, the filaments being unsupported in the stretch breaking zone, the fibres being removed over apertured delivery roll 11 by aspirating jet 17 to form an entangled yarn. The accumulation of static charge may be minimised by means of static bars 15 and/or the provision of porous cloth bags 16 containing finely ground calcium carbonate or other antistatic agent underneath the rolls and/or the use of filaments containing or treated with an antistatic agent. The entangled yarn may be further entangled by passage through entangling air jet 18. The yarns are substantially free from crunoidal loops. The continuous filaments are of polyethylene terephthalate, a 98/2 copolymer of poly(ethylene terephthalate / 5 - sulphoisophthalate sodium salt), nylon 66, rayon, aramid(poly - p - phenylene terephthalamide) or a copolymer of acrylonitrile methyl acrylate / sodium styrenesulphonate (91.5/8/0.5). A mixture of nylon and polyester filaments may be used. The filaments may be cold drawn or hot drawn (using heated shoe 14) between feed rolls 7, 8 and input rolls 9, 10. In example 5 a short heated shoe is used so that the fibres have different shrinkages. The tenacity of the yarn in g/denier is at least 45% of that of the filaments. The shrinkage, number of free ends and number of neps are specified.
