Patent DE-3304928-A1 (DE)
Inventor: WANGLER ALFRED
IPC: E04B1/38
Filed: 1983-02-12
Abstract: In the case of linear, plane and spatial constructions which are formed of a plurality of construction elements retained by connections, the problem arises to know how to obtain a multitude of construction forms with relatively few base elements of simple mounting. The answer is given by providing a construction element havig a support (TG) extending along a plane (E) and connected to a covering member (DG) on at least one surface side. It is thus possible with a support construction form to combine many different covering elements, for example from a decorative point of view. To obtain a detachable connection of the construction elements, a notch connection is used which presents certain advantages as to its simplicity and ease of handling, which provides a connection member (VG) with a stop element (HE) intended to be inserted into a notch recess, as well as a casing (G) arranged therethrough. The casing walls (W) form supporting elements (SE) to prevent the connection member (VG) from rotating with respect to the notch recess (RA).

Patent DE-3310293-A1 (DE)
Title: Support for books, files, tapes, blocks and the like
Inventor: MOSER WERNER
IPC: A47B65/00
Filed: 1983-03-22
Abstract: Supports according to the main patent exert a pressure on the articles to be supported and are connected by a spring band which produces the pressure. Solutions are also proposed, which by frictional connection between support elements and rolled up spring band end or by locking build up a resistance against forces which emanate from the supported articles in order to offer support to heavy articles also. Drawing 1, Fig. 6 shows a support which blocks in the application position. The spring band end is wound onto a roller-shaped body and there produces a frictional connection. The engagement between locking wheel and nose prevents rotation of the roller. The roller pins are connected to a housing part. If the support is moved away from the articles, the locking is released and the resistance is reduced to the spring force. Supports as described are in particular also suitable for compact tape cassettes, records and the like. Lateral brackets integrated in the supports also allow use as stands for individual articles such as picture frames, signs, panels and the like. <IMAGE>

Patent DE-3339628-A1 (DE)
Title: Unreinforced elastomer bearing for supporting building structures and parts of structures
Inventor: BATTERMANN WALTER
IPC: E04B1/36
Filed: 1983-11-02
Abstract: In the installed state, structural bearings in slab form made of rubber or rubber-like plastics without any reinforcing inserts are liable under the influence of canting movements of the parts of the structure being supported to the risk of shifting out of the joint, following a wedging effect. Instead of known complex adhesive bonds or positive connections, according to the invention this risk is countered by a system of crossing sharp-edged ribs or webs as limitations of depressions formed in the surface of the slab. The ribs run rectilinearly parallel to the side edges of the bearing slabs and fix them in all directions against otherwise possible displacing movements.

Title: Device for measuring displacements of a body without tilting error
Inventor: KLAPPER FRANZ DR
IPC: G01B11/00
Filed: 1983-12-21
Abstract: A device is provided for measuring the displacements of a body, without tilting error, by means of an electrical scanning unit and an electronic evaluation unit. It is particularly suitable for obtaining a correction signal for resetting the tilting errors caused in the case of a displacement, which is to be measured, of the body on a surface about a surface normal between a cruciform grid (2) firmly connected to the body and a co-ordinate system fixed in space. In order to obtain a correction signal for the resetting of random twists, the device has for the purpose of avoiding tilting errors a further scanning unit (9) which is arranged at a distance, determined by the desired sensitivity of twist detection, parallel to one of the two scanning units (8, 10). <IMAGE>
Patent DE-3402497-A1 (DE)
Title: Apparatus for cutting off wood and subsequently machining the wood sections at the side edges
IPC: B27B5/04
Filed: 1984-01-25
Abstract: An apparatus is proposed which enables wood, such as boards, planks, or the like, to be cut off and subsequently machined, e.g. trimmed, and for this purpose has a transverse conveyor, at least one cross-cut end-trimming tool arranged in the course of the transverse conveyor, an aligning table behind that with aligning units interacting in pairs, and following that a longitudinal conveyor leading to the cutting machine. In the known apparatuses of this generic type, the several wood sections obtained from a piece of wood by cutting off are successively put onto the aligning table and aligned. This involves a relatively high construction cost with considerable space requirement between the cross-cut end-trimming tool and the aligning table and also leads to a slow mode of operation and thus unsatisfactory working capacity. These disadvantages are rectified according to the invention owing to the fact that the aligning table 22 has a pair of aligning units 24 in each case on either side of each cutting plane S of a cross-cut end-trimming tool 23, and the wood sections 21a, 21b aligned by the individual aligning units 24 can be transported away in succession by means of the longitudinal conveyor 27 at predeterminable intervals. <IMAGE>

Title: Set of structural elements for forming grid structures
Inventor: ERTLE KARL ING GRAD
IPC: E04B1/19
Filed: 1984-04-11
Abstract: In the case of known sets of structural elements for forming grid structures, it is impossible for frameworks to be constructed or dismantled by only one person if using struts larger than a certain size. The invention thus proposes a set of structural elements for forming grid structures (1), into the joint parts (2) of which structural elements bolts (14) can be screwed. By means of pockets (8) situated at their ends (5), the struts (4) can be suspended on these bolts. It is only after the struts (4) have been suspended that they are braced with the joint parts (2) by turning the bolts (14). Removal of the struts (4) from a framework is effected in the reverse order. Since the struts (4) are initially only suspended, assembly can easily be carried out by one person. <IMAGE>
