Title: Rolling device for changing the location of parasol stands
Inventor: KASSEL HEINRICH DIPL ING
IPC: F16M11/42
Filed: 1982-07-15
Abstract: The invention "rolling device for changing the location of parasol stands" is intended to enable stands which are heavy for reasons of stability to be moved without great expenditure of force. The area of shade cast by a parasol moves as the sun moves from East to West. In order to keep the shade over a certain area during the period of sunshine, the position of the parasol has to be changed at certain intervals of time. This change of location is to be facilitated by means of the subject of the invention and to be capable of being arranged by anyone. According to the invention, the parasol stand is placed on a correspondingly dimensioned and shaped platform which is provided with rollers on the underside. The structure is shown in Fig. 1.     a) Base plate   b) Reinforcements on the underside   c) Rollers   d) Apron   e) Slot   f) Fixing bolt for stand.   <IMAGE>

Title: Axially reciprocating component, acted upon directly by combustion heat and provided with a heat shield, of a reciprocating internal combustion engine
Inventor: ZATECKY JOSEF DIPL ING
IPC: F01L3/02
Filed: 1982-10-01
Abstract: In the case of a reciprocating component, acted upon directly by combustion heat, of a reciprocating internal combustion engine, a ceramic heat shield is held directly on that side of the component which faces the incident heat. The heat shield used is a thin oxide ceramic plate which is flat at room temperature and to a large extent covers that side of the component which faces the incident heat. In this arrangement, the oxide ceramic plate is held on the component by a metallic retaining ring which accommodates it and encircles it. The bearing face on the component is designed in such a way that the oxide ceramic plate supported on it deforms with a slight convex curvature and this bending of the oxide ceramic plate is just great enough to ensure that the plate curvature is maintained at operating temperature but that the internal stresses in the plate are largely relieved due to the temperature drop prevailing between the top side and bottom side of the plate.
Patent DE-3236681-A1 (DE)
Title: Digital control comparator for passive electrical setpoint and actual-value transmitters
Inventor: DIESING HANS-WOLFGANG
IPC: G01D5/244
Filed: 1982-10-04
Abstract: Passive electrical sensors are compared with setpoint transmitters via voltage comparators in control loops. The detour via voltage values requires analog-electronic circuit expenditure requiring calibration and causes an unnecessarily high susceptibility to interference which accelerates the wear of electromechanical actuators. By comparison, a direct conversion of the sensor value into a frequency at the oscillator input of an otherwise purely digital control loop enables it to be integrated monolithically with a high yield. A dual-ramp comparator which, instead of a voltage, integrates the frequency by means of an up/down counter, switches the oscillator input from the sensor element to a corresponding setpoint element with the direction of counting. As a result, any drift in parameters of the active circuit parts becomes ineffective. By using the mains phase as a comparator clock, mains-synchronous interference is compensated for. The control accuracy is increased by suppressing asynchronous interference influences by two types of measures: a majority comparator which only switches the actuator output when a sequence of comparator results exhibits an "absolute" countermajority and a hysteresis which remains proportional to the setpoint set in each case over the entire range of values. Various setpoint transmitters, sensors and actuators can be processed in succession. <IMAGE>

Title: Method of obtaining a lasting deformation on a plate-shaped precast concrete part
IPC: B28B11/00
Filed: 1983-05-06
Abstract: The invention relates to a method of obtaining a lasting deformation on a plate-shaped precast concrete part. The precast concrete part is deformed at as early an instant as possible by applying a load directly after removal from the formwork and is held under load in this deformed state for a given time until, by an increase in the elastic modulus and by creep, the precast part retains the desired deformation even after removal of the load. The deformation applied must be greater by the back-deformation which occurs constantly. As a result of the invention, it becomes possible to manufacture plate-shaped precast concrete parts in considerably more economical methods as plate-shaped precast concrete parts can be manufactured in simple plane forms and the same forms can be used for variously curved precast parts.

Title: Seal for vertically arranged submerged lead-throughs of shafts, piston rods etc
Inventor: OERTEL RUDOLF DIPL ING
IPC: F03B11/00
Filed: 1983-05-19
Abstract: Bearings, compression glands or the like, which function in hydraulic systems under water must be protected against penetration of the latter or conversely against the escape of oil. To solve this problem, it is proposed according to the invention to arrange an air bell between the water and the machine element to be sealed off. In the example shown a footstep bearing is protected against water penetration by a first annular space 10 open towards the water but hermetically sealed off on the bearing side. The annular space 10 is enclosed by the bearing housing 4 and by the protective bush 9 connected to the rotor hub 1, which bush can rotate free of contact about the bearing housing 4. In order to compensate for leakage losses, compressed air, the supply of which is controlled by upper and lower switch point sensors 24, 21, can be fed by way of an airline 13. In addition, topping up with fresh oil can be performed by way of an oil line 12 entering at the lowest point of the sealed off space, whilst a packing collar 16 seals off the first annular space 10 from outside and an airline 13 provides venting. The device can in principle also be used for compression glands, compression gland bearings etc. in hydraulic machines. <IMAGE>
