Patent DE-3344430-A1 (DE)
Title: Adjustable ladder support
Inventor: VOSS ERNST-ULRICH
IPC: E06C7/44
Filed: 1983-12-08
Abstract: For the safe support of a ladder on uneven ground, a ladder support (1) is assembled from two tubes (2, 3) which are arranged movably and lockably inside one another and which are supported on a ground plate (5) via a joint (4). Situated on the outer tube (2) - at a distance from one another - are angular support elements (6, 7) which are arranged to receive the rungs of the respective ladder to be supported, the upper of the two angular support elements (6) being fastened vertically adjustably on the tube (2). For horizontal locking of the upright of the ladder, use is made of a locking device (14), by means of the holding plate (16) of which, interacting with a clamping plate (15) extending perpendicularly thereto, the upright can be fixed to the tube (2). The ladder support (1) can be used irrespective of the precise dimensions of the respective ladder and thus universally. <IMAGE>

IPC: H03J5/00
Filed: 1984-01-20
Abstract: 1. Method for identifying broadcast transmitters which are received by means of a broadcast set, particularly a car radio, with the assistance of the associated receiving frequency, characterized in that from stored information items on transmitting frequency, transmitter site with site coordinates and transmitter range of all transmitters located within the possible range of the broadcast set, all those sites of transmitters of which the transmitting frequency corresponds to the receiving frequency are selected, in that for a freely selectable reference transmitter which can be received at the location of the broadcast set, all transmitters with the same frequency as the reference transmitter are determined from the stored information items, that from the site coordinates and the transmitter ranges of the reference transmitter and of the transmitters with the same frequency, their service areas are determined and compared with the service areas of the selected transmitter sites determined from the selected site coordinates and the associated transmitter ranges, this comparison being based on a comparison of the distance of the transmitters, obtained from the site coordinates, and their range, that those of the selected transmitter sites of which the service area (sic) do not overlap with any of the service areas of the reference transmitter or of the transmitters with the same frequency are eliminated and that, if after elimination several transmitter sites remain, the method steps of selecting a next receivable reference transmitter, of determining the transmitters having the same frequencies as this transmitter, of checking for overlap with the service areas of the remaining transmitter sites and of eliminating transmitter sites in the case of non-overlap are repeated until only a single transmitter site remains which, together with the receiving frequency, unambiguously determines the broadcast transmitter.

Title: Bottle crate stacking mechanism - has grab mechanism held clear of base portion by sliding and turning bars
IPC: B65G57/03
Filed: 1984-02-08
Abstract: The stacking mechanism is particularly for bottle crates in several levels on pallets. A conveyor delivers the crates in rows, while a feed mechanism indexes the pallets, and a grab transfers the crates to them. A motor-driven pinion on the grab head meshes with a rack on an arch-shaped guide rail, so that the grab travels along the rail between conveyor and pallet. The grab head (12) comprises a base portion (32) and a grip mechanism (16) held clear of it by two or more bras (34). One bar at least extends through thebase portion and slides and turns in it, and the intervening distance between base portion and grip mechanism is adjustable by a device on the same side as the sliding bar. ADVANTAGE - High operating speed and simple construction.

Title: Method for operating a double-strip continuous casting mould for die-casting steel and a casting nozzle interacting with a double-strip continuous casting mould for carrying out the method
Inventor: ARTZ GERD
IPC: B22D11/06
Filed: 1984-03-17
Abstract: When casting steel under pressure, care must be taken that the sealing gap between the moving mould walls of the double-strip continuous casting mould and the fixed mouthpiece of the casting nozzle prevents the escape of molten steel counter to the casting direction at all times. In order to relieve the said seal of load in the region of the mouthpiece 2b of the casting nozzle in order to make the start-up process easier, a mode of operation is proposed in which the molten steel entering the mould space 4 as a free jet 16 first of all forms a molten pool 17 with a molten metal level 17% below the outlet 2> of the casting nozzle. Only after a run-in phase of several minutes is the ratio between the feed flow rate and the outlet flow rate moving at the casting speed altered in such a way that the molten steel finally fills the mould space completely. The associated casting nozzle 2 is characterised in that its mouthpiece 2b, including the sealing surface 2% interacting with the mould walls is composed of amorphous silica (SiO2) and that its smallest bore cross-section, which forms a restriction 15 that produces a free jet 16, lies in the mouthpiece. <IMAGE>

Title: Shut-off slide valve
Inventor: DAVID WALFRIED
IPC: F16K3/30
Filed: 1984-08-03
Abstract: The shut-off slide valve has a slide-valve housing in which a shut-off wedge actuable by the spindle is accommodated. The slide-valve housing is provided with an upper housing opening bounded by an inward-projecting housing rim and matched to the outer contour of the shut-off wedge, which opening is shut off in pressure-tight fashion from the inside by a cover which engages behind the housing rim. The cover bears an outer internally threaded stub into which is screwed a screw plug having a guide and seal for the spindle and a supporting abutment for the spindle collar. Inserted between the cover stub and the screw plug is a supporting ring against which are seated two supporting feet which come to rest from above on the housing rim. When the screw plug is tightened, the spindle collar is thereby clamped and the spindle sealed off and the cover is furthermore clamped in pressure-tight fashion to the housing. The cover stub is matched approximately to the width of the housing opening and the screw plug bears a recess on the inside to support the spindle collar and a continuous external thread on the outside.
