The invention pertains to a binding-in machine (40) for pressing in and joint forming books (1) which comprises a multitude of pressing devices (1) and assigned joint forming devices (42), as well as devices for feeding the books (1) and aligning the cased book blocks (2) relative to the cases (3) and for post-forming the rounded book blocks, wherein a forming rail (43.5) is provided that acts upon the fore edge cut (1b) of the book block, and wherein the book is supported on the spine (1a) and/or in the case joints (1c). The books are laterally taken hold of by means of a book gripper (30.1 or 30.2) that moves back and forward and transfers the vertically positioned books from an upstream transfer position (20.11 or 20.12) between the opened pressing plates (41.1) of a pressing device (41), wherein the books are deposited on an alignment table (43.1) with their spine (1a) in order to subsequently align and post-form the books (1) within the pressing device (41). A pre-formed book is gently transferred into the pressing device such that its form is preserved.
摘要:
An apparatus and method is disclosed for orienting the magnetic anisotropy of longitudinal patterned magnetic recording media. A disk-shaped longitudinal granular magnetic recording medium is provided having a high orientation ratio in the circumferential direction. The medium is then patterned to form a uniform array of magnetic islands. The magnetic islands are then irradiated with ions to increase the magnetic exchange coupling between the grains of each island. This aligns the axes of magnetic anisotropy of the individual grains with the average axis of magnetic anisotropy of the grains, thereby aligning the magnetic anisotropy of each island along the circumferential direction.

The backing of a previously rounded book block is accomplished, while the book block is clamped between oppositely disposed gripping jaws, by subjecting the spine region of the book block to composite forces resulting from imparting a swinging motion along an arcuate path to a pressing beam carrier, to cause the pressing beam to bend the book block sheets outwardly away from the center line of the block, and superimposing tangential sliding motion on the pressing beam as it acts on the book block in the region adjacent the edges of the spine to thereby controllably form creases in the opposite sides of the block.
摘要:
In a binding-in machine (40) for pressing in and joint forming books (1), the invention proposes that the delivery device (45) features a book gripper (45.1) with a pair of opposite joint gripping rails (45.4, 45.5) that take hold of the books (1) in the formed case joints (1c) and the distance between which can be varied, wherein the formed and pressed-in books (1) can be removed from the pressing devices (41) with said book gripper. The books (1) are reliably separated from the pressing plates (41.1) due to the inwardly directed movement of the joint gripping rails and subsequently pulled out of the pressing devices (41). The gripped removal makes it possible to realize a secondary forming or stabilizing of the formed case joints and to produce a glued connection between the case and the book block.

A continuous process is disclosed for the extraction of monomeric caprolactam and its oligomers as the raw polymer product obtained in the polymerization of polyamide-6 in which no fresh water, but processing water or previously used extraction water is used for the granulation.
摘要:
A device for backing rounded book blocks (2) clamped near the spine, by a pressing beam (9) and a slide (7) that accommodates the pressing beam (9) and can be alternately displaced along arc-shaped races (6) in a swinging fashion by driving means (17) in a height-adjustable supporting bearing (5) that is laterally supported against the effect of a spring element (29). Members are provided for controlling (21, 22, 32, 33) the lateral position of the supporting bearing (5) and for lowering and raising (10, 11, 12) the pressing beam into the starting position for its return stroke. An eccentric starting position is realized during the lowering of the pressing beam (9) on the spine (2a), in the form of a swinging position of the slide (7) that is offset toward the opposite side of the spine center (2b) referred to the respective side to be backed thereafter.
摘要:
The invention relates to an element, comprising a substrate with a surface roughness of less than 5 nm, with saturated bonds on the surface and an MPt3 film applied to at least one side of the substrate, with a magnetic anisotropy perpendicular to the plane of the film, with M=a metal of the 5th to 9th sub-group of the periodic table, nickel or gadolinium. The invention further relates to a method for production of the above and the use of said elements as a magnetic component, for example as a magnetic sensor or as a magneto-optical storage element.
摘要:
In the case of an inner book conveying channel having mutually adjustable lateral guides and having a height-adjustable inner book support, on which inner books are fed in an upright position while being laterally supported, for operationally reliable conveying of very thin inner books an inner book support (2) is provided with bottom lateral guides (9), which are preferably arranged on either side and height-adjustable jointly with the inner book support (2), and with middle lateral guides (12), which are positioned between the bottom lateral guides (9) and top lateral guides (11). Said middle lateral guides are freely displaceable along vertical guides and by virtue of height adjustment of the inner book support (2) are liftable by the bottom lateral guides (9) into a vertically offset position.
