Patent DE-3211206-A1 (DE)
Title: Holder for teaching and learning aids for child education
Inventor: WIDMANN FIDEL
IPC: G09B19/12
Filed: 1982-03-26
Abstract: The holder for teaching and learning aids has a support plate (1) to whose lower edge a footing strip (28) is attached. A teaching or learning aid such as a wall clock (6) for school children can be attached to the front bearing surface of the support plate (1) or placed on a footing strip (28) and leaned against the bearing surface. The upper edge of the support plate (1) makes a transition, via a narrowed neck part (16) with S-shaped borders, into a large oval suspension loop (13) with a suspension gripping aperture (14) which is likewise oval and is curved somewhat at the top. The height and width of this suspension loop substantially correspond to half the dimensions of the lower main part of the support plate (1). This can thus be easily handled even by children and, after being suspended, automatically swings into a perpendicular position. A display apparatus (3) between the support plate (1) and a supporting foot (2) articulated to the latter by its upper edge limits the ultimate pivoting travel with the thickened end of the display rod (21) and determines the normal support position by means of a locking apparatus which secures the support foot even in the position in which it is pivoted against the support plate (1). <IMAGE>
Patent DE-3212663-A1 (DE)
Title: Camshaft with variable timings
Inventor: MARTIN HARRY
IPC: F01L13/00
Filed: 1982-04-05
Abstract: Since conventional camshafts - with fixed timings - can only ever provide ideal timings for a particular, relatively narrow engine speed range, a camshaft which makes possible other, matched timings for each engine speed range should be used. This is achieved with a camshaft presented here by virtue of the fact that the cams can be spread since they are split transversely to the longitudinal axis of the shaft, one half of each cam being seated on an outer shaft and the other half on an inner shaft of two shafts arranged concentrically to one another. When the shafts are rotated relative to one another, the width of the cams is thus varied, i.e. the lines of symmetry of the cam halves form different angles. A concave contact surface of circular curvature on the valve side (if required tappet) makes possible the smooth transition from one cam half to the other.

Patent DE-3236302-A1 (DE)
Inventor: TENDULKAR GAUTAM
IPC: G06F13/36
Filed: 1982-09-30
Abstract: A multiprocessor system having a memory-programmable control of the type having a processor unit, coupling memories and input and output modules for transferring signals to and from a process which is to be controlled. Each processor unit is provided with a subprogram and a data memory which can be accessed directly, and a bus control unit releases access to the common system bus always for only one of the processor units. The access sequence and the access duration of the individual processor units to the common bus, via which the signals run to and from the controlled process, are fixed in a bus assignment matrix. In this manner, simple synchronization of the processor units is achieved. Moreover, guaranteed reaction times with respect to the process are possible. In addition to the duration, sequence, and frequency of the bus access of each processor unit in a bus cycle, the latest number bus window which must be seized by each processor unit can also be monitored by a bus monitoring device, thus insuring that guaranteed reaction times are possible.

Patent DE-3239478-A1 (DE)
Title: Method for forming a digital value proportional to the product of two electrical signals and application of the method in a device for measuring thermal output
Inventor: STARK REINHARD DIPL ING
IPC: G01K17/10
Filed: 1982-10-25
Abstract: The dual-slope method known for digitising an analog signal is modified for forming a product in that the first time interval (T0), which is constant per se and during which the one electrical signal (u1) is integrated up, exhibits a duration proportional to the magnitude of the second signal (no). The final integration value (ua1) reached at the end of the first time interval (T0) is thus proportional to the product of the two signals (u1, no). After that, a constant reference signal (ur) is integrated in the opposite direction until the original output voltage (uo) is reached again. This defines a second time interval (T1) during which a pulse train of constant frequency (fT) is counted into a pulse counter, at the outputs of which the desired digital value is available at the end of the second time interval (T1). The method described is used for a device for measuring thermal output, in which one signal is proportional to the advance/return temperature difference ( DELTA theta ) and the other signal is proportional to the rate of flow of the heat carrier, an ultrasonic measurement in accordance with the lambda locked-loop method being used for the rate of flow. <IMAGE>

Title: Electric motors with a safety brake
Inventor: SLAIHER SIGISMUND
IPC: H02K7/102
Filed: 1983-06-22
Abstract: The invention relates to electric motors with electromagnetic safety brakes. The invention relates in particular to those motors, especially actuating motors, which are instantaneously blocked in the event of power failure, that is to say must be firmly braked. According to the invention, the inertia of the brake is reduced by means of a cup-shaped brake drum (4) of small diameter, by means of the use of stator laminar sheet (10) for the braking magnet (9) and/or the use of the motor energising coil (2) entirely or partially as a braking coil. According to another variant, the braking magnet is provided outside the motor housing in order to prevent heat development, and the braking force is transmitted to the brake shoes using mechanical means - armature rod, braking cams. In order to reduce the energy requirement, and hence the heat requirement, of the braking magnet, an additional blocking device, driven by the electromagnet, can furthermore be provided, for example in the form of a wedge which is seated on an armature rod and can be pushed in between the ends of the brake shoes. <IMAGE>

Title: Greenhouse or similar device and method for conditioning the hall space of greenhouses or the like
IPC: A01G9/24
Filed: 1983-08-30
Abstract: A greenhouse or similar hall space with at least one supply opening and one outflow opening for air and a method for conditioning the climate in such greenhouses or the like, in particular in desert regions, are to afford a possibility for air conditioning of high efficiency. Additionally, an economical cleaning of the external air in the greenhouse interior is to be achieved. This is brought about in that the air is supplied in the floor region of the greenhouse and leaves the interior, thus provided with overpressure, in the roof region. The conditioning of the interior consequently takes place by means of rising cooling air with the side walls closed; the plant plane on the floor of the greenhouse is provided with adiabatically cooled air which is warmed as it rises and is extracted at a sufficient vertical distance from that plant plane. The correspondingly equipped greenhouse has in the floor region mouths of at least one air supply pipe and in the roof region the outflow opening(s). The external air is conducted through a washing space upstream of the air supply pipe, which the air leaves in an aerosol-free manner.

Title: Rolling-bearing cages of plastic with resilient external securing of the rolling bodies and process for their production
Inventor: LEGROM FRIEDRICH
IPC: B29C43/42
Filed: 1983-10-20
Abstract: The invention relates to the area of rolling-bearing cages made of engineering moulding compositions (plastics). It provides a simple and effective way of solving the technical problem of high demoulding forces of the slides in the injection mould, which serve for moulding externally the undercuts (8) holding the rolling bodies (2) in the cage. This is performed by the outer holding strips (8) being moulded by special notches (7) on the mould slides (6) in such a way that they can spring back during demoulding. This achieves on the one hand low demoulding forces, on the other hand easy fitting of the rolling bodies in the cage and at the same time their reliable securing. Requirements for enveloping circles which are intended to ensure the rolling-body, outboard and inboard guidance of the cage can be met in any event by virtue of the high precision which can be achieved. <IMAGE>
