Title: Heating regulation of an upright service water storage tank and device for implementing the regulation
Inventor: MOHR WILHELM
IPC: F24D19/10
Filed: 1981-09-30
Abstract: The heating regulation of a service water storage tank (5) as a component of a heating installation is to take place in such a manner that as long as possible burner operation times are achieved without impairing the efficiency of the heating installation. Use is made of a large service water storage tank (5) with an upper thermostat (9) and a lower thermostat (10). During winter operation, the heating of the service water takes place before the end of the daily night lowering phase. Only the lower thermostat (10) serves for control. Thus there is full heating at the end of the lowering time. The burner operation times are long. Recharging in the heating phase, which is hardly to be expected, only begins when the temperature falls below the value set at the upper thermostat (9). It runs until switched off by the upper or lower thermostat (9, 10). The same control as during the recharging in winter operation with switch-off by the lower thermostat (10) is to be envisaged during summer operation. <IMAGE>

Title: Face milling cutter
Inventor: HARTMANN FRITZ
IPC: B23C5/06
Filed: 1982-03-19
Abstract: A face milling cutter has indexable carbide inserts detachably fastened to the periphery of a tool body in such a way that the centre axes of the indexable carbide inserts each run approximately at a right angle to the centre axis of the tool body. One of the indexable carbide inserts is turned about a horizontal axis through an angle of 90 DEG  or essentially 90 DEG  relative to the other indexable carbide inserts in such a way that the plane formed by its cutting face is turned towards the workpiece surface. Furthermore, the cutting edge, interacting with the workpiece surface, of the turned indexable carbide insert is shifted forward by an amount in the direction of the workpiece surface, relative to the effective cutting edges of the other indexable carbide inserts. With a face milling cutter of this type, it is possible to achieve a high quality of surface finish (low roughness height) of the machined workpiece with simultaneously high feed, i.e. in short machining times.

Filed: 1982-07-05
Abstract: 1. A method for automatically demanding the measured signal value and identification signal in an alarm installation having a central unit and at least one signal line (ML) to which a plurality of signals (M) are connected, wherein in the case of cyclic demanding, in each signal (M) a time element (T1) influenced by the measured signal value by means of a measuring transducer (MW) is connected to the signal line (ML), and in the central unit the signal address is derived from the number of the increases of the conduction current (IL) effected thereby, and the measured signal value is derived from the length of the respective switching delay, characterised in that in each signal (M) the transit time (T) of the time element (T1) is controlled by means of an output signal (USU ) formed in a signal converter (SU) and representing the sum of the measured signal value and an identification signal (UMW + UK ), and in the central unit, in addition to the signal address, both the measured signal value and also the identification signal (K) of the respective signal is derived from the respective switching delay (T1 to Ti ).
Patent DE-3228418-A1 (DE)
Title: Mechanical combination-lock toy providing an automatic successful result
Inventor: BRANDT KLAUS B
IPC: A63F9/00
Filed: 1982-07-27
Abstract: The mechanical combination-lock toy providing an automatic successful result is a game of skill in which a secret number is to be found out by the displacement of a number of number rolls. This secret number is previously set on the device by an assistant. This can be repeated as often as required. The number of possible secret numbers is related to the number of number rolls present. A toy with five number rolls offers 99,999 possibilities. A toy with six number rolls offers 999,999 possibilities etc. Finding out the previously set secret number is possible in three ways: 1) by trying out all number combinations; 2) by listening during displacement of the number rolls; 3) by fingertip feeling during displacement of the number rolls. This is because during displacement of the number rolls, "signals" occur as a result of the rubbing of the locking cams on the locking discs. If the correct secret number is ultimately set on the toy by the number rolls, the successful result occurs: the core shaft with its locking cams springs out of the toy. Subsequently, the game can be repeated as often as desired with new secret numbers.

Title: Turbine-compressor set for supercharging internal-combustion engines, in particular for motor vehicles
Inventor: TUCZEK FRANZ DR ING
IPC: F02B37/22
Filed: 1982-09-11
Abstract: An impulse turbine having an adjustable impeller cross-section drives a piston compressor with an adjustable capacity via a transmission. A control device matches the impeller cross-section and the capacity to a predetermined turbine speed and a predetermined supercharging pressure, for an exhaust gas quantity which is present in each case and the air consumption of an internal-combustion engine associated therewith, or searches for the maximum possible impeller cross-section with which a predetermined supercharging pressure can be achieved. By means of said set, a constant supercharging pressure can be maintained at a constant speed of the set with heating of the air which is less than adiabatic, without any time delay on changing the engine speed, over a wide speed range of the internal-combustion engine, starting at a speed which is somewhat above idling.

Title: Pack for foodstuffs
Inventor: HERTEL REINHARD
IPC: B65D77/28
Filed: 1982-11-15
Abstract: The invention relates to a novel pack for foodstuffs, beverages and the like. Many foodstuffs taken on journeys, excursions or picnics are packaged in cup-like containers made of paper, cardboard or plastic which are closed at the top by means of a foil. To consume these foodstuffs or beverages, aids, for example small spoons for yogurt, are often necessary. To ensure that the respective aids necessary for comsuming the foodstuffs are also available, the pack contains, in addition to the foodstuffs or beverages, an item of cutlery, such as a spoon, fork or one or more drinking straws, appropriate for comsuming them. This reliably avoids the relatively common untoward occurrence of forgetting to take the items of cutlery normally necessary for consuming foodstuffs. The items of cutlery is appropriately arranged in a recess of the pack; this ensures that the item of cutlery can be extracted in a hygienic manner and in a clean state.
