Patent DE-3240840-A1 (DE)
Title: Bicycle hub
IPC: B62M11/18
Filed: 1982-11-05
Abstract: Bicycle hub with 6-gear auxiliary transmission without double changing with planetary gears for bicycles. Two inner gears I and II are present, I being 1:1 and II bringing about a step-up, said gears being provided by a two-speed planetary speed gear system P1. In conjunction with one (or two) additional planetary gear systems PA for the 3 groups L/M/H the gears 1, 2/3, 4/5, 6 are produced. Here, the sequence from I and II in L and H is normal. However in the central group M, the arrangement is such that the sequence from I and II is reversed, that is to say e.g. when changing upwards the sequence is II to I! As a result, it is not necessary to change gear when changing the groups L into M. Therefore, the customary double change is omitted when changing the group. As a result of the reversal in group M, the jump between 3rd gear and 4th gear can also be different to that between I/II. Because the arrangement is also such that in group L a translation is brought about but in group H in the 5th gear there is a branching with the same planetary gear system (type A:PA; type B:P3; type C:PC), the two jumps between the 4th, 5th and 6th gear together are as large as the one jump between the 1st and 2nd gear. Therefore, all the jumps go with the translations i are increasing. In the preferred embodiment A only two single planetary gear systems are present. The preferred gear change takes place in an S form by means of a single manual change lever 51. <IMAGE>

Patent DE-3307291-A1 (DE)
Title: Extended lever arm on the crank drive (eccentric)
Inventor: DREHER ALFONS
IPC: F16H21/20
Filed: 1983-03-02
Abstract: Input and output shaft - extended lever arm - which is twice the length of the (conventional lever arm) - coupled - equal torque at the two shafts. The conventional force cannot be carried away. The extended lever arm at the output and at the input shaft carries the force away. The difference in the two lever arms is 1:1 and determines the consumption. The ratio of the two lever arms of 1:2 results in a saving of force of 50%. The difference in the length of the two lever arms can theoretically be infinite. N.B.: The extended lever arm is equal to the radius of the transmission discs. Overall there is an energy saving and less pollution of the environment.

Patent DE-3320377-A1 (DE)
Title: Magnetic-field stirrer
Inventor: MOOG BERND DIPL CHEM
IPC: B01F15/00
Filed: 1983-06-06
Abstract: A magnetic-field stirrer for chemical laboratories, especially for radioactive (hot) cells. In order to reduce the mechanical wear on the motor-driven magnetic stirrers and the frequent failure of the magnetic stirrers which are located in so-called hot cells, a magnetic-field stirrer has been developed in which no motor is required. The electronics which are susceptible to radioactive damage can be fitted outside the hot cells (control simplification). The control of the rotation speed can additionally be carried out by a computer; monitoring of the rotation of the stirring vane is possible. The force of the magnetic field is controllable if necessary. The magnetic field is generated in the normal manner by coils which are geometrically arranged in a suitable manner. The invention thus relates to a magnetic-field stirrer without a motor, in which the rotation speed is produced electronically by controlling the intensity and direction of a magnetic field. Energy saving in comparison with a motor-driven magnetic stirrer is also achieved.

Patent DE-3327638-A1 (DE)
Title: Porous mouldings
Inventor: JOSEFIAK CHRISTOPH DIPL CHEM D
IPC: B29C48/10
Filed: 1983-07-30
Abstract: The invention relates to porous mouldings, a process for the production thereof, and a suitable apparatus for carrying out the process. The process comprises forcing a homogeneous, single-phase liquid mixture of one or more polymers and one or more mixture partners which are liquid at the preparation temperature of the mixture through a nozzle from top to bottom at a linear velocity V1 into a cooling liquid which does not dissolve the polymer at the cooling temperature, or only does so to an insignificant extent. The cooling liquid is kept in a channel-like zone surround by a wall from the point at which the extruded mixture enters the cooling liquid until at least the point at which solidification commences, the velocity of the cooling liquid in this zone V2 being kept smaller than V1; V2 may also be 0 or have the opposite sign to V1. The cooling liquid is preferably kept in a cooling device in the shape of a U-tube, in which the level is controlled by metering in at the inlet and/or outlet point. The process is particularly suitable for the production of mouldings such as membranes, in particular hollow fibre membranes made from hydrophilic polymers, such as polyamides, and made from polymers of low molecular weight, and for the processing of polymer/mixture partner mixtures having a relatively low polymer content.

Title: Domestic building roof of precast reinforced concrete compound units with integrated rainwater gutter
Inventor: BEENKEN HANS HEINRICH DIPL ING
IPC: E04B7/02
Filed: 1983-10-28
Abstract: The invention relates to a domestic building roof construction, preferably of a precast reinforced concrete type. The attached drawing, page 7, shows a domestic building roof of only three different large-format roof elements, which is preferably set up on a domestic building ground plan according to the Beenken building system, which is based on a 3.60 m x 3.60 m grid system. The points of intersection of the grid form the bearings for the individual elements, the bearings at the ridge being designed at the same time as chimneys, which are put to such use, as required, by a chimney top or are covered by a slab. The supporting beam running round the outside of the individual roof elements has an integral rainwater gutter. This roof construction together with the bearing structure of the Beenken system (Beenken Patent Application 1803573) makes it possible to use a modular system. Consequently, mass production can be achieved by using just a few differently shaped large-format roof parts and, together with the rapid assembly, a domestic building can be protected against penetrating moisture and the production costs are significantly reduced.

Patent DE-3417648-A1 (DE)
Title: Overvoltage suppressor
Inventor: MAIER GUENTHER DIPL ING
IPC: H01T1/15
Filed: 1984-05-12
Abstract: For correct dissipation of the heat from the varistors (1) of overvoltage suppressors, which heat is produced both in the steady-state operating mode and during temporary switching and atmospheric voltage surges, heat-conducting elements (2) are provided. The heat of the varistors (1) is initially introduced into the heat conducting elements (2) in the axial direction, via the end surface (2') of said heat conducting elements (2), and is dissipated radially from said heat conducting elements (2) via their outer surfaces to the insulating housing (6, 6'). In this case, the heat conducting element (2) is connected in a heat-conducting manner to the insulating housing (6). The entire outer surface of the varistor (1) is spaced apart from the inner wall of the insulating housing (6, 6') by means of a space (12) which is filled with insulating gas. The heat conducting element (2) is broadened outside the diameter region of the varistor (1) and is at the same time used for adjusting the varistors (1) during their installation, and additionally prevents accelerations of the varistors (1) when shocks act on the overvoltage suppressor. <IMAGE>
Patent DE-3417870-A1 (DE)
Title: Press for pressing a glued and dried book block
Inventor: GROLLIMUND MAX
IPC: B42C13/00
Filed: 1984-05-14
Abstract: The press has a contact plate for the spine and two press rams (2, 3), on each of which a press jaw (4, 5) is articulated. Each of the two press jaws (4, 5) is held by a spring (8, 9) in a holding position in which the level surface parts of the jaws move towards each other, starting from the contact plate (12). The jaws are pivoted, during pressing, into a pressing position by the pressure of the book block against the force of the springs (8, 9), in which pressing position the level parts of the pressing surfaces diverge, so that, in the pressing position, the spine of the block has a lesser thickness than the other parts of the block. After the pressing operation, the spine then expands again somewhat, though without becoming thicker than the remaining parts. The sections (4c, 5c) bordering the level sections (4b, 5b) of the pressing surfaces are curved so that, during the pressing operation, each point of the pressing surface moves away from the contact plate (12) and so lifts the book block from the plate. <IMAGE>
