Patent DE-3126326-A1 (DE)
Title: Multiple-cycloid compass
Inventor: SCHNEIDER PETER MARIA
IPC: B43L11/08
Filed: 1981-07-03
Abstract: The invention relates to the depiction by drawing of a large number of geometrically harmonic figures, especially cycloids, and their modifications. The solution according to the invention is that one or more rotating wheels (figures) are linked by adhesive friction or toothing to a base wheel or base figure (2) locked on a guide rail (see drawing (4)) by additional push-on shaft mountings. By horizontal pivoting about the axis of the base wheel, a corresponding rotation of the rotating wheels (1) is achieved as a consequence of the adhesive friction or toothing, in the course of which one (or more) radially adjustable pencil(s), fixed to the extended shaft of a particular rotating wheel, draw(s) the geometrical figure on a paper inserted underneath. Rubbers (6) or tension springs between the shaft mountings bring about rolling of the rotating figures and the movement of the shaft mountings along the guide rail in the case of rotating figures which are not positioned centrally or have corners (triangle, square, etc.) or elliptical shapes. A special plug-in design of the individual parts permits rapid conversion and a broad embodiment of the drawing instrument. The instrument is suitable as a creative toy, as a drawing instrument or as a presentation or demonstration instrument in schools. <IMAGE>

Title: Internal combustion engine, especially with air cooling
Inventor: ECKERT ROLF DIPL ING
IPC: F01P5/02
Filed: 1981-07-23
Abstract: The invention relates especially to an air-cooled internal combustion engine with a hydrostatically driven cooling air fan and with an exhaust system which is ribbed in the area of the internal combustion engine, the cooling air fan being reversible in its direction of rotation as a function of the temperature in such a way that the air flow produced by the cooling air fan following cold starting of the engine is first heated on the exhaust system and moved over the cylinder heads or cylinders to the cooling air fan and is reversed into its normal direction of movement only when the engine is warmed up. <IMAGE>
Patent DE-3132580-A1 (DE)
Title: Spring brake cylinder
Inventor: BARTLECHNER MANFRED
IPC: B60T17/08
Filed: 1981-08-18
Abstract: Spring brake cylinder, particularly for rail vehicles. The spring brake cylinder has an energy storage spring supported in axially non-displaceable fashion at one end. The energy storage spring acts on a spring-clamping piston. Arranged between the spring-clamping piston and the piston rod of the clamping piston is a non-self-locking screw drive, which is subject to torque loading when the cylinder is subjected to braking. The screw drive consists of two parts, one of which is mounted in a manner fixed in terms of rotation and the other part is mounted so as to be rotatable relative to the other. The rotatably mounted part of the screw drive can be braked solid by means of a locking clutch which can be operated at will. A switching device for the release of the locking clutch if the pressure medium fails is provided. The torque output by the screw drive when the cylinder is subjected to braking is supported between the piston and the piston rod and between the piston and the screw drive, with the result that the cylinder casing is not subjected to the torque. The rotatable part of the screw drive is furthermore locked with respect to the piston by the locking clutch. It is advantageous if the locking clutch is a friction spring with an actuable end and a non-actuable end. The non-actuable end of the friction spring can fit with prestress over a cylindrical surface on the rotatable part of the screw drive as long as there is an additional damping device to damp the suddenly released force of the spring cylinder when the latter is released mechanically. To avoid the need for a damping device and to allow the spring cylinder to be released as slowly as desired, the switchable end of the friction spring fits with prestress over a cylindrical surface on the piston. <IMAGE>

Title: Optimisation of the discharge system of monopolar secondary batteries
Inventor: MANZ RICHARD DIPL ING
IPC: H01M50/50
Filed: 1983-02-03
Abstract: The most important characteristic variables which determine the current density distribution and the resistive self-discharge losses are named on the basis of a mathematical model for a parallel-plate arrangement with infinitesimal elements of a battery. Using an example, the primary current density distribution in a starter battery is shown without being influenced by overvoltages which produce homogenisation but cause losses. Measures for achieving a symmetrical, more homogeneous primary current density distribution with smaller maximum values and consequentially reduced reaction causes for the occurrence of overvoltage influences on the secondary and tertiary current distribution are specified, together with design proposals for batteries having a high structural shape. Furthermore, it is shown how a forced circulation of electrolyte can be achieved by gravity circulation by objective design of the electrodes in a lead-acid accumulator having a high structural shape.

Patent DE-3306519-A1 (DE)
Title: Clutch control device
Inventor: ARAI KENJI
IPC: B60W10/06
Filed: 1983-02-24
Abstract: A device for automatically controlling the engagement/release of a clutch has a control element for operating the clutch; the control element, which responds to a control signal, which is related to an engine speed signal, operates the clutch in that engagement of the clutch is performed at a speed of travel which is related to the engine speed. During engagement of the clutch the engine speed is monitored and the control element can be correspondingly actuated by the operating signal relating to the engine speed. Consequently the engagement of the clutch is brought about at a speed of travel which is precisely adjusted to the operation of the accelerator pedal. In particular a so-called half-engagement of the clutch can be performed smoothly and surely and the feel of the driver during the engagement process thereby greatly improved.

Title: Constructional kits for operating panels
Inventor: GUTMAIR FRANZ
IPC: G05G1/01
Filed: 1983-03-25
Abstract: The basic material for all operating panels is the keyboard 4.5 of Figure 1 (with the symbol ' kappa ' instead of the symbol ' lambda ' when there is no speech input). For simpler applications, substrates, preferably the substrate 4.4 and the substrate 4.3 with '=' instead of ',' are sufficient. To this are added, as needed, one or two switching keys of Figure 2 or at least two of the three switching keys of Figure 3. A pass reader can protect against misuse of the unit concerned. Naturally there is a display and, with a separate operating panel, it can be accommodated both on this panel and on the device to be operated. In the case of more differentiated sequence conditions, a sequence switch is added (Figures 4 to 6). Operating panels for objects such as machine tools, which receive further condition switches and control elements dependent thereon, and the 'stop' key for spontaneously switching from 'critical' to standby circuit have not been included here. <IMAGE>
