Abstract: 1308333 Chipping and sawing machine KOCKUM SODERHAMN AB 5 March 1970 [5 March 1969] 10591/70 Heading B5L A chipping and sawing machine comprises a frame, chipping members 11, 12 rotatably journalled in the frame for cutting the side portions of a log into chips while making two opposite sides of the log phane and parallel to each other, sawing members 14, 15 for sawing at least one board from each side of the reduced log, and driving means for the cutting and sawing members respectively. The members 11, 12 are truncated cones which have their smaller ends facing each other and are rotatable about an axis transverse to a longitudinal axis of said log, and the members each have a plurality of knife members spaced axially and radially. Each knife member has a first edge disposed to cut in a first plane parallel to the grain of the log and a second edge merging with the first edge and disposed in a second plane intersecting the first plane to cut across the grain. The sawing members 14, 15 are closely spaced behind the chipping members 11, 12 in the direction of log movement so that the log is guided by the chipping members during sawing and does not warp, twist or bend before sawing in consequence of the variations in the inner tensions of the log caused by the chipping operation. As described the members 11, 12 are adjustably spaced and driven in synchronism. Each knife member thereon may have guide surfaces for guiding the log, and openings may be provided adjacent each knife member to receive and pass through chips cut from the log. Guides 23, 24 may be provided between the members 11, 12 and the sawing members 14, 15 and the log may be fed by a conveyer 13. The members 14, 15 which may be band or frame saw blades are adjustably spaced, and further sawing members 18, 19 may be provided.

[Class 94 (i)] Articles a to be wrapped are brought by a conveyer 14 and are pushed on to a pivoted carrier 19 when the latter is in its lowest inclined position as shown. During its passage on to the carrier the article becomes partially wrapped in a length of web w which has been drawn from a supply roll at the end of the wrapping of the preceding article. The carrier is now raised, by a cam and follower 38, 39, into a horizontal position and an arm 50 carrying a roller 51, which may be freely mounted or positively driven, is swung counterclockwise about its pivot 52 by a second cam and follower. The web passes between a positively driven roller 46 and the roller 51 whereby the web is drawn downwardly into a loop. Coacting cutters 70, 71 are operated by a third cam and follower, the portion of the web between its severed end and the bottom right-hand corner of the article being utilised for completing the covering of the bottom side of the article as it is passed, by a pusher 105, to the delivery station. The ends of the parcel are folded by known means. The arm 50 is then raised again and the portion of the web left hanging over the roller 46 is used for beginning the wrapping of the next article. Specification 551,523 is referred to.

Abstract: 782,210. Heating springs by passage of current. POFFERI, G. April 13, 1955 [April 15, 1954], No. 10649/55. Class 39(3) [Also in Group XXII] An upholstery or other spring 5 is heated by passage of current therethrough for a predetermined time and is annealed by cooling, e.g. by air from a fan or by a liquid bath. The spring is held slightly compressed between arcuate contacts 4a, 7a curved to the curvature of the spring, the ends of which extend beyond the contacts so that the ends are substantially not heated and simultaneously with the heating, each end of the spring is seized by a binding member 3 of a machine of a known kind and bound to an adjacent turn of the spring so as to form an upholstery spring. with closed end turns. The contacts 4a, 7a form stop members engaging the end turns of the spring. The upper contact 7 has a groove 7a engaging the spring and is con-' nected by insulating strips 6 to the lower contact 4a mounted on a plate 4. Leads 8 from the contacts are connected to a stepdown transformer 9 to which current is supplied through a tapping switch 11 and through a timing switch 12, which is operated by a tappet 12a actuated by a cam 13. The synchronization of the heating and binding of the spring is ensured by mounting the cam 13 on a shaft 14 of the binding machine, so that the tappet 12a is lowered to close the switch only during the binding operation.

An overload current, which will operate, e.g. the conventional electromagnetic trip mechanism 18 of a circuit-breaker and thereby release its moving contact arm 6 by means of a latch 12, also causes operation of sensitive quick-acting switching means (such as a sensitive relay, thyratron or thyristor) which serves to discharge a previously charged capacitor (not shown) through an electromagnetic coil 30 which then repels a copper ring 32 on a rod 26 secured to " fast " contact 2 to break the contacts 2, 4 before the conventional trip mechanism 18 acts. The operating mechanism 10, which applies a closing force to contact 4 until tripping, is that of Specification 934,210, and the latch 12 is that of Specification 849,658. Contact 2 is restored by its spring 38, or is latched in its open position by balls 54 pressed into a tapering aperture between the rod 26A and a hole 50A by a light spring 56, Fig. 2. Contact arm 6, in moving " slow " contact 4 to its contacts-open position, releases this ball latch by striking a pin 60 on a link 62. The opening of contact 2 may be utilized to trip the latch 12 of contact arm 6, Fig. 3 (not shown), and trip mechanism 18 is then dispensed with.
