Title: Sorption heat pump
Inventor: DIESING HARTMUTH
IPC: F25B30/04
Filed: 1982-01-13
Abstract: The present invention relates to a sorption heat pump, especially absorption heat pump, with a condenser and an absorber, which are both constructed as heat exchangers and heat a consumer in parallel arrangement. In such a parallel flow heating of the consumer, it can happen that the temperature on the consumer side at the output of the condenser does not have the same level as the temperature which is set on the consumer side at the return to the absorber. To provide temperature equality here and moreover to sufficiently supercool the absorber, and also to ensure a sufficient heat removal at the absorber and in order to keep the condensation temperature low, the invention consists in that the parallel branch of the consumer leading via the condenser is conducted to a tapping of a pipe coil within the absorber.

Title: Radial ply tyre with renewed tread rubber
Inventor: THIELEMANN KLAUS ING GRAD
IPC: B60C9/20
Filed: 1982-01-16
Abstract: The invention is based on radial ply tyres with renewed tread rubber, in which part of the belt plies has also been renewed. In order to eliminate substantially detaching effects in the parting face between the new tread rubber on the one hand and the part of the radial ply tyre lying underneath on the other hand, the renewed tread rubber has on its inner face a cord fabric ply, which in terms of its cord angle coincides at least substantially with the upper-lying, non-renewed belt ply. Due to the cord fabric ply laid in this way, shear stresses between this ply and the cord fabric ply located underneath are virtually eliminated.

Title: Method and device for conditioning an air throughput signal
Inventor: HUETTEN HEINRICH DIPL ING
IPC: F02D41/24
Filed: 1982-01-29
Abstract: In a method and a device for conditioning an air throughput signal from the air intake pipe of an internal combustion engine, the pulsation-related periodic alternating component of the unconditioned air throughput signal is coupled out and added to it again with inverted phase. This results in a conditioned air throughput signal in which the periodic alternating component is eliminated. The alternating component is preferably coupled out by means of a decoupling capacitor. A phase reversing element, such as an inverter amplifier, connected to the decoupling capacitor, and an adding amplifier can be used for reversing the phase of the alternating component and for conditioning the signal. Instead, it is also possible, dispensing with the phase reversing element, to apply the unconditioned air throughput signal, on the one hand, and the coupled-out alternating component, on the other hand, to the inputs of a differential amplifier.

Title: Method and device for operating cooling towers which serve to recool cooling water, in particular natural draught cooling towers
Inventor: MILLER CARL W
IPC: F28F25/00
Filed: 1982-02-15
Abstract: The invention relates to a method and a device for operating cooling towers which serve to recool cooling water, in particular natural draught cooling towers, in which in the event of falling external temperatures in conjunction with a change in the air throughput in the cooling tower a water temperature is maintained which prevents the formation of dangerous ice deposits from the cooling water raining down; according to the invention it is provided in this arrangement that, essentially in conjunction with maintenance of the feed temperature and rate of flow of the water raining down, the air throughput of the cooling tower is reduced by restricting a tower cross-section, which determines the amount of air, as a function of the discharge temperature of the cooled water.

Title: Solitaire game in the form of an assembled body with lateral surfaces which can be twisted as desired
Inventor: MOLL WALTER DR
IPC: A63F9/08
Filed: 1982-02-17
Abstract: A three-dimensional solitaire game in the shape of a body having equal lateral surfaces, which is assembled by joining together part-bodies which are movable relative to one another, in a manner such that each lateral surface has a rotatable central piece, edge pieces and corner pieces and the part-bodies forming any desired lateral surface can be jointly twisted about the centre of the lateral surface, is, according to the invention, not in the conventional cube shape but in the shape of a regular body with lateral surfaces which are not at right angles to each other, especially in the shape of a regular dodecahedron or of a tetrahedron. As a result of the non-orthogonal relationship of the lateral surfaces and axes of rotation to each other and, in the case of the dodecahedron, as a result of the increased number of part-bodies, the difficulty of the solitaire game is increased in comparison to the known cube.

Title: Device for the locking and releasable securing of a bonnet-shaped or plate-shaped pivoting part on a relatively immovable part
Inventor: MUELLER RICHARD
IPC: E05B83/24
Filed: 1982-04-26
Abstract: In a device for the locking and releasable securing of a bonnet-shaped or plate-shaped pivoting part on a relatively immovable part, for example an engine bonnet (11), for the uniform force distribution and for the prevention of rattling noises there is a single locking bar (3) which extends parallel to the pivot axis of the pivoting part and which is mounted rotatably to a limited extent on one part, for example the fixed part, and is equipped at the ends with coupling elements (4, 5). These each possess a cylindrical recess (16, 17) which is radially open in one direction and is hemispherically closed on the inside and into which a correspondingly shaped rubber element (18, 19) is inserted for the elastically supported plug-in reception of a locking ball (23 or 24) connected to the other (pivotable) part (11) by means of a locking plate (6 or 7). On part of the circumference, each coupling element (4, 5) has in the axis of the recess (16, 17) a slot (21 and 22 resp.), through which the locking plate (6 and 7 resp.) passes when the locking ball (23 and 24 resp.) is held closed. By means of a spring (15) which engages on the coupling element (4, 5) and at the other end is clamped fixedly relative to the system and which can be subjected to torsion, the locking parts (4, 5 and 23, 24) are held in the closed position by means of the locking bar (3) and, as a result of the rotation of the locking bar, are released in order to swing up the pivoting part (11). <IMAGE>

Title: Circuit arrangement for processing pulse sequences by means of a Fourier processor
Inventor: SCHLICHT RUDOLF DIPL ING
IPC: G06F17/14
Filed: 1982-07-19
Abstract: To adapt the signal length (number of pulses) to be processed to an integral power of the base of the algorithm of a fast Fourier transform, the spectral analyser carries out a group-by-group serial/parallel conversion of the pulse signal sequence, delay devices with graded shortened storage times being allocated to the outgoing parallel lines. According to this, a required number of replacement values can be integrated into the signal sequence, avoiding dead times and buffer stores.

Title: Controlling circuit arrangement in a forming press
Inventor: KLASSEN ALFONS
IPC: G05B19/23
Filed: 1982-08-20
Abstract: Controlling circuit arrangement in a forming press having a programmable computer. A counter is connected to the computer and a first adder/subtracter is connected to the output of the counter for each working-cylinder/piston arrangement, whilst an electrical command variable for the slide movement can be picked up at the counter output. Moreover, each working-cylinder/piston arrangement is assigned, on the slide, an angle encoder which is likewise connected to the first adder/subtracter of this working-cylinder/piston arrangement. It enters the actual value of the slide travel into the first adder/subtracter. A digital/analog converter is connected to the output of this adder/subtracter and a controller likewise assigned to this working-cylinder/piston arrangement is connected to the digital/analog converter. The controller acts on a regulating valve in the line between the regulating pump and its working-cylinder/piston arrangement. It controls in accordance with the difference between the command variable generated by the computer and the actual value picked up by the angle encoder. Located upstream and downstream of the regulating valve are pressure-measuring devices for the hydraulic fluid which belong to the pump control circuit for the regulating pump. A working pressure difference can be maintained between the input and the output of the regulating valve by means of the pump control circuit. <IMAGE>

Title: Infinitely adjustable and lockable spanner with adjustable display of the set spanner opening
Inventor: MUELLER HEINZ
IPC: B25B13/14
Filed: 1982-11-30
Abstract: The spanner, which is infinitely adjustable by hand, replaces a multiplicity of ring spanners of various openings and is also usable as a holding device. In the known adjustable spanners, the set spanner openings are easily altered, and damage nuts thereby or no longer grip nuts which are already damaged. An infinitely lockable adjusting device prevents set spanner openings from moving in an uncontrolled manner. The adjusting and locking operations are performed simply by turning the hand in one direction. An adjustable display device displays the set spanner openings. The spanner body only requires drop-forged shaping and hence a minimum of production expenditure. The counter-jaw slide is guided and held in and on the spanner head and the spindle-like push rod of the counter-jaw slide is guided and held in the spanner body of U-shaped hollow construction at the bottom, the counter-jaw slide and the spindle-like push rod being pushed into the spanner head and spanner body, respectively, by the leverage produced by an inserted nut. The self-releasing or reinforced-locking action of the adjusting and locking device is produced by the greater pitch of the right-hand thread compared with the pitch of the left-hand thread of the adjusting and locking device.

Patent DE-3246782-A1 (DE)
Title: Pendulum-piston pump
Inventor: BECKER ERICH
IPC: F04B53/14
Filed: 1982-12-17
Abstract: A pendulum-piston pump has at least one sealing sleeve (10) which has a section extending radially and retained at least partially by the piston part (9), and a lip section (12) which bears on the cylinder wall (13) in a sealing manner. In one embodiment of the invention, the wall thickness (d) of the sleeve section (11) extending radially is greater than the wall thickness (b) of the lip section (12) of the sealing sleeve. Sufficiently strong buttressing for the lateral forces arising at the pendulum piston is achieved at the same time as a good fit of the lip section (12). According to a refinement, the internal diameter of the pump cylinder in the middle section of the piston travel is narrowed slightly. In an important development of the pendulum-piston pump (101) there is located on the pendulum piston (3) a second sealing sleeve (110) which, with its lip zone (112), points towards the crank chamber (19). This produces, along with strong lateral support for the pendulum piston (3), also an additional sealing effect which very largely prevents any air from flowing across from the crank chamber (19) during the intake stroke. As a result, the pump runs particularly smoothly and quietly (Figure 7). <IMAGE>

Title: Apparatus for the tearing conversion of fibre slivers
IPC: B65H69/06
Filed: 1982-12-23
Abstract: In an apparatus for the tearing conversion of fibre slivers, finite chemical and/or natural fibres are torn to the desired length and to the stacking diagram necessary for the subsequent process by means of a plurality of successively arranged tearing and drafting zones and delivery rollers. Between the individual machines of the overall apparatus for tearing conversion, a transport of the fibre slivers takes place in cans, in which two or more sliver pieces separated from one another are often located as a result of faults in preceding parts of the installation. In order to ensure that the fibre sliver running into the can is uninterrupted, that is to say in one piece, it is proposed, in order to avoid faults in the various parts of the installation during tearing conversion which are caused by sliver pieces not connected together, that there be arranged between the last tearing or drafting head and the delivery rollers a device for splicing the fibre-sliver ends by means of aerodynamic swirling. By means of this splicing device, fibre-sliver ends can be connected directly to one another on the tearing machine, so that the fibre sliver deposited in the can still consists of a single piece, even when interruptions of the fibre sliver have occurred as a result of faults in the tearing machine.
