摘要:
A rock drilling machine of the self-feeding, integrated type which is designed to operate in situ in a drill hole. The rock drilling machine comprises a drive unit (1), an anchoring unit (2), and a feeding unit (3) which is active between the anchoring unit (2) and the drive unit (1). The drive unit (1) comprises a hydraulic power assembly (5, 8) at the rear end of the unit, a drill bit (21) which is rotatable at the front end of the unit, a guide (10) with a longitudinal cavity (23), which guide extends between the hydraulic power assembly and the drill head and connects these non-rotatably to each other, a rotatable drive shaft (22) which extends from the hydraulic power assembly, through the said cavity in the guide, for rotation of the drill bit, and first securing devices (17) in order to be able to anchor the drive unit releasably in the drill hole. The anchoring unit (2) comprises at least one control element (30') around the said guide, and second securing devices (31, 31') in order to anchor the control element releasably by means of engagement against the drill hole wall, and the feeding unit (3) comprises at least three individually manoeuvrable hydraulic cylinders (60-62) between the anchoring unit and the drive unit for feeding the drill bit forwards in the desired direction, when the said first securing devices are inactive, and when the said second securing devices actively anchor the control element in the drill hole.

In the application of preprinted film wrappings around packing containers it is sometimes required that the text or decorative pattern of the wrapping should be located in a certain position in relation to the edges of the finished packing container. A method of film wrapping around an object, e.g. a packing container, is described in which a film web is joined to a waste material web and is advanced with the help of this until the decoration is situated in a predetermined position. Subsequently the packing containers are wrapped while the film web is delivered from a film roll whereupon the sealing is performed on a previously unused part of the film web. Apparatus for carrying out the method is described which comprises co-operating sealing jaws and a conveyor consisting of two parallel parts.

In apparatus having at least two roll pairs and/or stretch rolls each having a driving means with an amplifier for speed control, the speed control reference for each drive is developed by summing signals developed in adjacent control circuits such as to obtain a relationship in which, for example, for the second drive the signal is V.sub.0 (1 + S.sub.1) (1 + S.sub.2) where V.sub.0 is a basic speed reference signal and S.sub.1 and S.sub.2 desired relative speed differences for first and second drives to thereby permit speed adjustments.
摘要:
An absorbent pant article in the form of boxer shorts includes a garment shell including a front body panel, a back body panel and a crotch panel made of elastic web material. The pant also includes an absorbent core, side seams connecting the front body panel to the back body panel, a pair of leg openings and hanging legs. The leg openings are located in the crotch panel and do not extend into the front and back body panels, and side seams extend into the crotch panel. The width of the crotch panel in a relaxed condition of the elastic web material, as measured between the side seams of the article, is at least 7% larger than the width of any of the front and back body panels in a relaxed condition of the respective elastic web material.

摘要:
An absorption article such as a pant diaper, having a liquid-permeable topsheet, a liquid-impermeable backsheet and an absorption body positioned therebetween, the article having a front end portion, a rear end portion, and a crotch portion lying therebetween, the rear end portion and the adjacent part of the crotch portion having a transverse elastic system, a rear leg elastic system which runs between the two longitudinal side edges of the article along the leg cutout of the article in the rear part of the crotch portion and crosses the crotch portion essentially parallel to the transverse center line of the article. The article has, on each side of the absorption body, a pocket for temporary storage of liquid, the extent of the pocket being limited by the longitudinal side edge of the absorption body, the transverse elastic system and the rear leg elastic system.

A disposable diaper in which elastic which provides elasticized leg cuffs is accommodated in a pocket of material formed by either a facing sheet or a backing sheet of the diaper. The pocket extends along each longitudinal edge portion of the diaper. Fastening member for fastening the diaper around a wearer are affixed to the diaper between the facing sheet and the backing sheet.

The present invention relates to an apparatus for use in conjunction with a machine, such as a wheel-mounted loader, road planing machine or the like, to equalize the effect of ground-surface irregularities. The apparatus includes a frame disposed in the movement direction of the machine and a planing tool. The apparatus also includes a bogie-assembly which is mounted on the front end of the frame and extends parallel to the frame. The bogie-assembly includes two pivot wheels and a linking device which is pivotally mounted between the frame and an intermediate unit connected to the planing tool.
