Patent DE-3042927-A1 (DE)
Title: Energy economiser for polyphase induction motors - has two triacs conducting differently at very light loads for smooth operation and max. energy saving
Inventor: HEDGES RHEY W
IPC: H02P27/02
Filed: 1980-11-14
Abstract: A standard three-phase induction motor starts with all three of its input connections connected to the three-phase power line. Two of these connections are through triacs which remain continuously conducting below the motor's particular most energy-efficient speed, which is above about 95% of synchronous speed. This assures full starting torque and undiminished overload handling capability. The triacs, in response to a control signal, may open the circuits over a sufficiently wide portion of the sine wave input voltage to maintain the particular efficient speed under all rated load conditions. The DC control voltage which determines the operation of the triacs is generated by a frequency discriminator circuit which receives its information from a load detecting device that is frequency modulated by load/speed related properties inherent in induction motors.

Patent DE-3104079-A1 (DE)
Title: Process for preparing rolled strips from an aluminium alloy for manufacturing two-part cans
Inventor: ALTHOFF JUERGEN HEIN DR ING DI
IPC: C22F1/04
Filed: 1981-02-06
Abstract: The invention relates to a process for preparing rolled strips from an aluminium alloy for manufacturing drinks cans or the like. With a view to simplifying the manufacture and facilitating the repeated use (recycling) of the material of used drinks cans, considerable efforts have been made for years to provide an aluminium alloy which is equally suitable for manufacturing the can bodies and the can covers. Because of the very different requirements regarding the rolled strips for manufacturing can covers on the one hand, and for manufacturing one-part can bodies by deep-drawing and ironing, on the other hand, it had not been possible hitherto to solve this problem. According to the invention, an aluminium alloy is proposed which has as its main constituents from 1.15 to 2.0 % of Mn, from 0.85 to 2.0 % of Si, from 0.25 to 0.75 % of Mg, from 0.2 to 1.0 % of Fe, the remainder being aluminium, and which, employing known process steps, is rolled down to a suitable intermediate thickness, is then subjected to recrystallisation annealing at from 450 to 580 DEG C and can then be processed, while certain conditions for the cool-down rate and the rolling-down degree as a function of the required final strength are adhered to, to give a strip of the required final thickness. Figure 4 shows for a number of final strength factors (Rm) the associated values for the minimum cool-down rate (V) and the minimum rolling-down degree ( phi ) for treating the intermediate strip recrystallisation -annealed at from 450 to 580 DEG C. <IMAGE>

Title: Office hole-punch of folded construction
Inventor: KAESTNER DIETER DR ING DR
IPC: B26F1/36
Filed: 1981-02-11
Abstract: The invention relates to an office hole-punch of folded construction which is made of a high-polymer thermoplastic material, and is used to perforate thin two-dimensional structures in the home, at school and at the office. The aim of the invention is to develop an office hole-punch which is characterised by a simple structure, a minimum number of components, the small amount of time and material and the low level of costs entailed by the manufacturing, joining and assembly process and the fact that there is no need for surface finishing. According to the invention, the object is achieved in that the basic body of the office hole-punch is made of a thermoplastic material using an original moulding method, the start-of-cut systems, which are designed as film hinges, acting simultaneously as movement mechanisms. The said film hinges connect the baseplate, the central plate, the pressure plate and the tongue, which is formed in the central plate to act as a spring element, such that they cannot be released, so that the office hole-punch has a level two-dimensional structure in the unmounted condition. The office hole-punch is completed, after the basic body has been folded, by the joining and insertion of the punching elements into the guide bores and into the apertures of the pressure plate and by inserting and fastening the tongue in the guide situated on the underside of the pressure plate.

Title: Steplessly arrestable accelerator pedal for motor vehicles
Inventor: MILLER KARL
IPC: G05G1/60
Filed: 1981-07-02
Abstract: In order to allow the driver of a motor vehicle to operate the accelerator with a fully relaxed position of the muscles and nerves of the right foot and at the same time to achieve a petrol saving of up to 10% through the rest position of the accelerator pedal, the accelerator pedal is merely provided with a step which allows the shoe to engage. The foot's own weight is thereby sufficient to be able to steplessly arrest the accelerator pedal. The shoe is transferred from the operating position for the braking process without the slightest resistance. In the process the accelerator pedal springs back. Fig. 1 shows an upright accelerator pedal (11) with step (12) according to the invention and the vehicle floor (16) of a vehicle. For the functioning of this invention, the accelerator pedal (11) together with step (12), shoe (13) and vehicle floor (16) must form one unit. In this the shoe tip (14) is engaged on the step (12) and the shoe heel (15) placed on the vehicle floor (16). <IMAGE>

Title: Process and plant for the thermal treatment of sludge
Inventor: KOGLIN BODO DR ING
IPC: C02F11/18
Filed: 1981-08-29
Abstract: In the thermal treatment of waste water sludge, the pressure is increased high enough so that no gas separation takes place during conditioning and the resulting gases remain dissolved in the sludge, so that the pH of the sludge is decreased. To separate off gas, the pressure is then somewhat reduced at a roughly constant temperature. Because of the absence of gas separation in the conditioner-reactor (20), a plurality of vertical tubular reactors (18), connected one after the other, can be used. A pressure-reducing means (21) in the form of a throttle valve is connected between the conditioner-reactor (20) and a downstream gas separation vessel (22). <IMAGE>
