Title: Stamp holder
Inventor: THOMA WALTER
IPC: B41K1/58
Filed: 1983-05-03
Abstract: A stamp holder (1) (Fig. 1) has two rows of finger-like projections for holding stamps (3) to be inserted between them. The stamp holder essentially comprises a holding section (2) containing the stamp- holding rows (16) and a fastening section (4). The holding section (2) is connected to the fastening section (4) in a laterally pivotable manner by means of pivoting joints (11). As a result of this, the holding section (2) can be pivoted sideways, until one stamp-holding row (16) rests on the base. In this inclined position, only one row of the stamp holder can still be loaded with stamps (3), but its total height is reduced, allowing it to fit even into shallow drawers in this position. In the central position, with a total height which is somewhat greater, for accommodation in correspondingly larger drawers, both stamp-holding rows (16) can be loaded, on the other hand. Fingers which engage in slotted rails in the drawer and are located in the fastening section (4) can be provided for connection to a drawer. When sheet metal drawers are used, the stamp holder can also be secured by means of permanent magnets (24). A catch coupling (12) is provided especially for fastening the holding section (2) in the central position. <IMAGE>

Title: Roofer's batten measuring tape
Inventor: MEDWED WILLI
IPC: G01B3/10
Filed: 1983-09-27
Abstract: Roofer's batten measuring tape: Up to now it has been necessary to work out laboriously from case to case the dimensioning required for mounting roof battens. The entire work of computation is eliminated with the aid of the measuring tape according to the invention. This is achieved when, in addition to the normal centimetre calibration, the measuring tape, which is kept appropriately wide, is provided with a batten calibration scale, mounted below said centimetre calibration, from 320 to 350 mm for each rafter length in an easy-to-read fashion. The batten calibration scale is subdivided into three different colour fields, e.g. green, yellow, orange. The fields, constructed as a scale, indicate the respective batten calibration from 320 to 350 mm, top edge to top edge. The roofer's batten measuring tape is applied approx. two to four cm below the peak of the ridge, depending on the calibration. It is therefore possible, before fastening the first batten, for the latter to be displaced by approx. 10 mm upwards or downwards, until the adjustment point on the tape is reached. Alternatively, the measuring tape is applied to the upper edge of the first batten, and measurement is carried out up to approx. two to four cm below the peak of the ridge, depending on calibration. No matter what rafter length is specified, it is possible to view the measuring tape once applied, and the exact batten calibration can be read off conveniently. The roofer's batten measuring tape consists of two main parts, specifically the device for rolling up and rolling out the tape, and the measuring tape, which is provided with the coloured scales.

Inventor: IDSELIS MANFRED
IPC: H01P5/10
Filed: 1983-10-25
Abstract: The invention relates to an arrangement for balancing and transformation lines in the transmission points of broadcasting stations. Balancing and transformation lines are used as the transition between in each case one cable which is unbalanced with respect to earth and one double line which is balanced with respect to earth for the connection of an antenna, which is balanced with respect to earth, to a transmitter having an output which is unbalanced with respect to earth, a cable balancing network being arranged parallel to the cable and a plurality of balancing and transformation lines being arranged side-by-side. The invention is based on the object of reducing the respective separation between the balancing and transformation lines with minimum cross-coupling. This is achieved according to the invention in that the cable balancing networks and the cables which are unbalanced with respect to earth are arranged alternately offset through 90 DEG  with respect to one another, so that the associated electrical fields are polarised alternately vertically and horizontally and the balancing and transformation lines are at a small distance from one another, with minimum cross-coupling. <IMAGE>

Title: Mast-foot joint for surfboards
Inventor: ALLGAIER JOSEF
IPC: B63B35/79
Filed: 1983-11-09
Abstract: A mast-foot joint for surfboards consists of two plastic rings (10, 12) which engage one inside the other with certain axial clearance and which each have a support plate (18 or 20). A mast holder (30) is fastened to the support plate (18). The support plate (20) is equipped with a push-in pin (22) which can be snapped into a corresponding mast-foot bush. The joint can therefore be rotated in the mast-foot bush and can be released from the surfboard if a certain tensile force is exceeded. In the inserted position it permits all-round inclination of the mast and, on account of the elastic deformability of the rings (10, 12), has a shock-absorbing effect in the event of sudden stresses exerted on the board by the mast. <IMAGE>
