Patent DE-3225730-A1 (DE)
Title: Machine tool
Inventor: WILLEMIN PAUL
IPC: B23Q11/10
Filed: 1982-07-09
Abstract: The support (10) of the chuck serves as a seat for the segments (11a), has radial channels (19) and is surrounded by an outer ring (17). This outer ring (17) has an inner chamber (18) into which the radial channels (19) lead. The chamber (18) is connected via a line (21) to a source of cooling oil under pressure. This oil flows into the interior of the chuck (4) and floods the workpiece (15) clamped in it, including the machined surface (23), then flows down on the outside of the chuck (4) and in this way removes the chips which cannot penetrate into the interior of the chuck, since the pressure oil flows from inside to outside through all intermediate spaces between the various elements of the chuck and through the centre of the chuck. <IMAGE>

Patent DE-3229839-A1 (DE)
Title: Compact movable floor heating system
Inventor: COLLET WERNER
IPC: F24D3/14
Filed: 1982-08-11
Abstract: Heating units of various systems are offered for caravans, vending vehicles and boats. However, they do not fulfil the requirements which make possible a comfortable stay in the winter months. Test results unequivocally show that although these heating units provide up to 28 DEG C at table or head height, the foot region remains cold. Only a floor heating system can solve this. Since said system can only be retrofitted in camping vehicles at great expense, however, only a "movable floor heating system" can solve the problem. In a modification of the "movable floor heating system", P 3203428.8, the "compact movable floor heating system" represents an installation which contains in the heating plate all the additional elements, such as a heating device, equalisation device, pump, etc. Thus, any assembling and additional space requirement for these installations is avoided.

Title: Control arrangement for a supercharged internal combustion engine
Inventor: MADERTHANER KARL
IPC: F02B3/06
Filed: 1982-12-21
Abstract: A control arrangement for a supercharged internal combustion engine, especially for a diesel internal combustion engine, comprises an injection pump having a speed governor, and a full load stop, movable as a function of the speed of the internal combustion engine, for limiting or release of the injection quantity. The full load stop is designed, for example, as a three-dimensional cam, which in the direction of its second dimension is dependent on the air mass, which varies in accordance with the degree of charging. For optimum measurement of the air mass, the air mass-dependent shaping of the enveloping surface of the three-dimensional cam can be described as a function of the characteristic variables internal combustion engine speed, charge air pressure and charge air temperature.

Patent DE-3307949-A1 (DE)
Title: Safety temperature limiter
Inventor: BACHHOFER WALTER
IPC: H01H37/70
Filed: 1983-03-07
Abstract: A safety temperature limiter for switching off an electrical circuit on reaching a desired disconnection temperature, consisting of a housing having stationary contacts (4), of a slide (5) which carries contact links (6) which interact with the stationary contacts and is guided in the housing, of a spring-loaded switching lever (7) which is supported in the housing (1) and locks the slide (5) in its switched-on position, and of a thermal-expansion sensor (11) which interacts with the switching lever (7) and, on reaching the desired disconnection temperature, pulls the switching lever end (7a) back from the track of a locking projection so that the slide (7) can be guided into its switched-off position under the influence of a spring which acts on it in the longitudinal direction, the spring being supported on one arm of an angled lever (13). In order to block the slide in the switched-off position until the temperature which has been sensed has fallen below the desired disconnection temperature, the slide (5) has a recess (24) on its longitudinal side facing the second arm (13b) of the angled lever (13), and the switching lever end (7a) which interacts with the locking projection (12) of the slide (5) is acted on in the direction of the slide (5) by a spring force which, up to a temperature which is defined below the desired disconnection temperature, increases above a spring lateral force which is exerted by the angled lever (13) on the slide (5), so that the end which is provided with the recess (24) can be pivoted by means of the slide which is locked by means of the second angled lever arm (13b) which is latched in the recess (24) when the sensed temperature falls to or below the defined temperature, by means of the switching lever end (7a), which presses on the locking projection (12), against the spring lateral force which is exerted by the angled lever (13), and, in consequence, the second angled lever arm (13b) is lifted out of the recess (24) of the slide (5). <IMAGE>

Title: Electronic proximity switch with a rectifier following the oscillator
Inventor: JACOB LOTHAR DIPL ING
IPC: H03K17/95
Filed: 1983-06-24
Abstract: The invention relates to an electronic proximity switch with an oscillator and a rectifier following the oscillator, the rectified voltage of which actuates a threshold switch which controls a load switch. To be able to evaluate very small output signals and very small amplitude changes of the oscillator and to keep the current consumption, particularly of the rectifier, very small, an averaging rectifier with two transistors T1 and T2 is used, the base of T2 of which is connected to the emitter of T1 and the base of T1 of which is connected to the collector of T2. Between the emitter of T1 and the collector of T2, a diode D1 is connected with the anode to the emitter of T1. The rectified voltage is dropped across the collector resistor of T1. The diode causes the transistor T1 to be conductive during the entire negative halfwave of the input current. A temperature-dependent influencing of the rectified voltage is avoided. <IMAGE>

Title: DC commutator machine, and a method for its production
Inventor: SCHMIDER FRITZ ING GRAD
IPC: H02K25/00
Filed: 1983-07-08
Abstract: In a very small motor having a flat or planar air gap, the rotor (50) has a small diameter supporting element (44) which is mounted on the shaft (43), and shaped coils (47, 48) consisting of stove-enamelled wire are bonded to the external circumference of said rotor (50), using their radially inner sections, and project in a cantilever manner into the planar air gap (53). In this way, a rotor (50) is obtained having a very small axial moment of inertia, also known as GD<2>, resulting in very short acceleration times. In addition, the coils are very well cooled. Such a motor is particularly suitable for signal-recording or signal-reproduction apparatuses. The arrangement of the coils of the rotor is symmetrical, and a very simple, compact construction of the motor results. <IMAGE>

Title: Appliance for projection-copying a mask onto a workpiece
Inventor: TABARELLI WERNER DR
IPC: G03F9/00
Filed: 1984-02-15
Abstract: For the purpose of adjusting a device for projection-copying of masks (2) onto a semicoductor substrate (6), adjustment marks (8) are exposed with wide-band adjusting light (11) in order to eliminate intensity fluctuations of the reflected signal in the region of a mark field. The adjustment error caused by the wide-band character of the adjusting light (11) is eliminated by checking the spectrum of the adjusting light by means of a spectrometric device, and by determining the best adjustment or focusing position taking into account the frequency dependence of the projection objective (5) in the spectral composition of the adjusting light. The spectrometric device may be a diffraction spectrometer (26) or an optionally insertable filter. <IMAGE>
