Patent DE-3003854-A1 (DE)
Title: Step-ladder providing compact storage - has pivoting steps which are horizontal in working position but vertical when not in use
Inventor: KUEMMERLIN WALTER
IPC: E06C1/39
Filed: 1980-02-02
Abstract: A step-ladder has a pair of front legs (201) hinged to a pair of rear legs (202). The front legs consist of two main side members (203) with pivots (218) to support the steps (220). The inner ends of the steps are pivoted to a bar (211) which is also connected by a pivot (242) to the rear legs. When the legs are swung apart to their working position the bar brings all the steps to the horizontal position to provide level steps. At the same time the bar increases the rigidity of the side members. When the legs are brought together the bar swings the steps so that they are aligned with the main side members and so need less storage space.

Title: Coking coal blend of higher stability - by adding emulsified distn. residue of crude oil to preheated coal
Inventor: HARDERS OTTO
IPC: C10B57/04
Filed: 1980-03-29
Abstract: Blast furnace coke is made of hard coal of low coking quality by grinding, preheating, mixing with binders, compacting and carbonizing in an oven chamber. The preferred binder is the distillation residue of crude oil, emulsified in water, and used as admixture to the preheated coal charge. The coal is preheated to a temp. where, after admixture of the binder emulsion, the temp. in the mixture exceeds 100 deg.C. This results in a higher stability of the coal blend and of the resulting coke cake.

Title: Underfloor heating slab - with deep drawn thermoplastic foil bonded to polystyrene foam plate
Inventor: FREITAG DIETER
IPC: F24D3/14
Filed: 1980-10-02
Abstract: A slab for use as flooring for underfloor heating consists of a deep-drawn thermoplastic foil with several parallel raised strips at right angles to each other, each with spaced semi-circular notches for the heating pipes. Detent wedges on the sides effect a snap fit. Distributed raised circles between the strips support the pipes.

Title: Spoked wheel-shaped spacer for concrete reinforcements
IPC: E04C5/20
Filed: 1981-07-03
Abstract: In a spoked wheel-shaped spacer (10) made of plastic, which serves for supporting reinforcement bars (20) in concrete construction members, an outer circumferential ring (11) is connected to a central ring segment (13) bearing the reinforcement bar (20) by means of radially extending spoke webs (14, 14'). A radial cut-out (16) bounded on both sides by guide-surface webs (17, 18) serves for feeding through the reinforcement bar (20) as far as the bearing points in the central ring segment. In order to hold the reinforcement bar more securely in the spacer (10) and to prevent it from falling out or being pushed out when subjected to higher stresses, a sawtooth-shaped profiled wedge (21) rising in the feed-through direction is to be formed with its wedge tip (22) on the inner end of one guide-surface web (17), the steep surface (30) of the sawtooth profile is to face the bearing point in the central ring segment, and the sawtooth wedge (21) is to be pivotable in the spacer with its steep-surface end into a gap (27) kept free from spoke webs, the other guide-surface web (18) merging continuously into the central ring segment (13). <IMAGE>

Title: Method for producing a protective element for optical fibres
Inventor: HERFF ROBERT ING GRAD
IPC: G02B6/44
Filed: 1981-07-15
Abstract: The invention relates to a method for producing a protective element made from plastic for optical fibres, which has reinforcing fibres which generate a longitudinal compression and are let into the plastic or are arranged in a force-closed fashion on the plastic. The object is to provide a protective element which prevents the rise in attenuation in optical fibres in the case of low temperatures. This is essentially achieved by bringing the optical fibres or fibre, the reinforcing fibres and the plastic of the protective element to a temperature which is below the lowest temperature to be expected in operation of the optical fibres, in order to produce in the process the force-closed connection between the plastic and the reinforcing fibres. The invention is chiefly applied in optical fibre cables and optical fibre lines, which can be exposed to low temperatures during operation.

Title: Method and circuit arrangement for transmitting information signals between line connecting devices of a digital switching system
Inventor: BITZINGER RUDOLF DIPL ING
IPC: H04Q11/04
Filed: 1981-09-15
Abstract: The invention relates to a method and a circuit arrangement for transmitting information signals in accordance with a time-division-multiplex principle in a digital switching system to which a highway system (LB) (which is operated in a directionally dependent manner and has line connecting devices (ST1 to STn) contained therein) and line circuits (T1 to Tm) connected thereto belong. According to the invention, one time cell of time cells which occur repeatedly and cyclically in a first time-division-multiplex frame is made available (as the receiving time cell for the reception of information signals) to each line connecting device (ST1 to STn) or to mutually corresponding line circuits (T1 to Tm) of all the line connecting devices (ST1 to STn), and, in a second time-division multiplex frame which is repeated periodically at the repetition frequency of the time cells, a time slot is allocated to the line circuits (T1 to Tm) which are connected to the respective line connecting device (ST1 to STn) or to each line connecting device (ST1 to STn). The information signals which are to be transmitted are emitted by a transmitting line connecting device (ST1) to the highway system (LB) at times which take into account the transmission time to a receiving line connecting device (STn), before being received in the relevant receiving line connecting device (STn). <IMAGE>

Title: Single-plate friction clutch for motor vehicles
Inventor: SAUER WILLI ING GRAD
IPC: F16D13/64
Filed: 1981-10-29
Abstract: A single-plate friction clutch for motor vehicles has an axially displaceable driver plate which carries the friction linings and is connected in torsionally rigid fashion at its hub to a toothed driveshaft of the operating mechanism. To damp the torque transmitted from the driver plate to the driveshaft, rolling driver elements, preferably driver balls, engaging in the toothing of the shaft are employed and these are connected to the hub of the driver plate by an elastic interlayer prestressed in the installed position of the driver plate. A single-plate friction clutch of this kind is distinguished by complete freedom from play between the driving part (driver plate) and the driven part (driveshaft of the operating mechanism) in the direction of rotation. Rattling noises in the idling phase of the engine are thereby reliably avoided.
