Patent DE-3041826-A1 (DE)
Title: Mobile overhead working platform - has screwed spindle turned by boom extension movement actuating safety switch
Inventor: STECHERT HERMANN
IPC: B66F17/00
Filed: 1980-11-06
Abstract: The mobile overhead working platform comprises a derricking and extensible boom with detectors for the boom angle and telescoping movement, these preventing further derricking out under overload conditions. Parallel to the derricking axis (B) of the boom (4) a screwed spindle (15) is mounted on the latter, turning with the telescoping movement of the boom sections (5,6). Rotation of the spindle causes movement of a switch lug (16), which cannot turn, this in turn cutting out the extension movement of the boom by actuating a switch (18). The switch is adjustable in the direction in which the lug is thrust by the spindle. On the boom base (3) and coaxial to the derricking axis (B) is a cam (21), acting on the same switch (18), which is mounted on the boom, and moving it dependent on the derricking angle.

Patent DE-3043433-A1 (DE)
Title: Knitted fabric modification - uses local stitch bonding for selective stitch movement blocks
IPC: D06M23/06
Filed: 1980-11-18
Abstract: Local bonding points are inserted into the knitted fabric, over its surface, to inhibit stitch movement to alter the knitted structure. Specifically the local bonding points are imposed points or lines over the knitted fabric surface, using a fluid, gas or mechanical means, together with the application of heat using a HF heater. When using hydraulic pressure, the fluid is delivered at 40-50 atm. to impose a bonding or felting action. A fluid can be used which has a chemical reaction with the fibres, giving a partial dissolving action which is then arrested to form a bond, giving a structured partial bonding action at selected points. A mechanical bonding action is achieved by the use of needles or an engraved roller, together with or without heat and/or a fluid. A pair of pressure rollers bears against the points where the stitches are to be bonded, and a preheater can be used. The process allows the fabric to be modified at local points and zones, in a durable form, to give structured fabric stability for garment mfg. applications.

Title: Method for compensating for the inter-pulse interference of PAM and digital signals at the receiving end
Inventor: TROENDLE KARLHEINZ PROF DR ING
IPC: H04L25/04
Filed: 1981-02-04
Abstract: During the transmission of pulse-amplitude-modulated signals, particularly of digital signals, mutual interference of the received pulses occurs which is called inter-pulse interference. According to the proposed method, the transmitted signal is subjected to a nonlinear transformation which has the effect that the inter-pulse interference at the receiving end disappears. The transformation of the transmitted signal has the consequence that its weighting (number of steps) increases. According to Figure 9, a nonlinear equalisation or inverse transformation is required at the receiving end. <IMAGE>

Title: Device for collecting sunlight which has been concentrated by a water lens roof
Inventor: KEMMLER KARL
IPC: F24S23/30
Filed: 1981-11-24
Abstract: The rays refracted by a path of a water lens roof show a strip of maximum light concentration which slowly changes its position. The device for collecting sunlight which has been concentrated by a water lens roof serves to keep a chain of solar cells, which supply electric current, constantly in this region of maximum light concentration. It consists essentially of a vertically and horizontally displaceable crosspiece which supports on its base the solar cells. The vertical movement is effected with the aid of two water containers serving as traction weights. According to whether they are full or empty, the crosspiece rises or falls. Two further containers are required for the horizontal displacement. Figure 2 shows the four necessary containers. The water is taken from the roof water and pumped up again when a container has reached its deepest position. Electronically controlled brakes ensure that the solar cells always receive as much light as possible. <IMAGE>

Title: Apparatus for increasing the adhesion of the wheels of a vehicle on slippery ground which is not skid-proof or load-bearing
Inventor: DIEKMANN KLAUS ING GRAD
IPC: B60B39/00
Filed: 1982-01-12
Abstract: In sunken or elevated garages, driving in and out often causes great difficulties, particularly in winter time, when snow and ice occur. In the event of snow or ice, the access to sunken or elevated garages has to be swept, salted, heated or otherwise cleared and made driveable. It can be equally difficult to drive up inclines on ground which is not load-bearing and not skid-proof. A number of suggestions have been made in the past, and implemented, to overcome these difficulties. Among these, the costs are very high in some cases or the effect is not sufficiently lasting. On the basis of this state of the art, the inventor has set himself the object of developing an apparatus by means of which good adhesion of the vehicle wheels on the ground is achieved. The apparatus is to be economically priced, but is also to be for use only in case of need and is not to exhibit the disadvantages of a permanently installed apparatus. This object is achieved, according to the invention, in that two flexible, profiled strips of rubber, plastic, textile or similar material are rolled out at the upper end of the inclined carriageway at the width of a vehicle's track and over the snow or black ice, up to the garage. The vehicle can then be driven up and/or down satisfactorily on the track thus created. Thereafter the strips can be rolled up again and stored in dry conditions in the garage.
