Patent DE-3023521-A1 (DE)
Title: Supporting structure for underfloor heating coil - uses flanged sheets attached to floor rafters to form trough holding coil and insulation
Inventor: BADEWITZ HANS
IPC: F24D3/14
Filed: 1980-06-24
Abstract: The under floor heating system with a heating coil uses supports which can be suspended from the floor joists. These can consist of sheets flanged at one end so that they pass around the tops of the rafters, then lie inside the space between the rafters at low level. Their other ends can then overlap and are secured together. This forms a trough or a well to hold an insulating layer as well as the heating coil and its supports, all remaining below the level of the floor, carried by the rafters.

Title: Peripheral switches switching state determn. - by supplying start signal to first of series-connected pick=ups and reporting switching state via same line by time defined signal
Inventor: HOETTEN ARNOLD DIPL ING
IPC: H02J13/00
Filed: 1980-08-09
Abstract: Method for ascertaining the switching condition of a number of peripheral switches each assigned to a pick-up such, as voice-frequency pick-ups, provides units for evaluating the data received from the central unit, sorting the data and forwarded by means of a series connected control. A start signal is supplied via a line to the first of the series connected pick-ups and this line is used to report back the switching state of the associated switch, or a disruption in the associated transmission system, by means of a time defined answering signal. The end of the answering impulse of the first pick-up initiates the start signal for the second pick-up via the same line until other end of an interrogation cycle is reported back via the same line via a time varied answer pulse of a terminal or end element.

Abstract: In the prodn. of aq. CaBr2 soln. (I) by reacting CaCO3 (II) and Ca formate (III) in water with Br2 at elevated temp., 0.02-0.1 (0.03) wt.% spindle oil (IV) (viscosity 20-250, pref. 54 mPa.s at 20 deg.C) is added to the suspension of (II) in aq. (III) soln. and then the Br2 is metered in, the reaction mixt. being kept at 50-60 deg.C. (I) is used in drilling for petroleum and natural gas. The addn. of (IV) prevents frothing due to CO2 evolution, which takes place continuously. In an example, 257.5 (wt.)pts. (II), 325 pts. (III) and 0.42 pt. (IV) (viscosity 54 mPa.s at 20 deg.C) were suspended in 916 pts. water. After heating to 50 deg.C, the stirred mixt. was treated with 800pts. Br2 in 6 h, keeping the temp. at 50-60 deg.C by cooling. The CO2 formed was released without frothing. When reaction was complete, the mixt. was cooled and filtered to remoVe a small amt. of unreacted (II). 1963 pts. colourless (I) with a CaBr2 content of 51.5 wt.% and density of 1.7 were obtd. If (IV) was omitted, strong frothing occurred and the reaction had to be stopped after a short time.

Title: Process for relining metallurgical vessels
Inventor: PIRET JACQUES
IPC: C21C5/44
Filed: 1981-05-26
Abstract: The invention provides for the relining of metallurgical vessels, in particular in the region of their tapping holes or the like, in order to compensate for wear due to operation, a central jet of a highly oxidising gas, preferably pure oxygen, being directed onto the damaged site by a concentric jet of a gaseous fuel which contains refractory materials in suspension for the lining. The direction of the jet is preferably at an angle to the axis of the tapping hole, so that individual regions can be specifically refurbished. Furthermore, maintaining the said angle, with a circular jet, the entire wall region in the surroundings of the tapping hole can be refurbished, while the jet is advanced in the axis of the tapping hole. Special burners are used for the process, which are expediently constructed with an angled end section and not only permit the mentioned concentric jet conditions, but moreover further have a cooling jacket so that overheating is avoided.

Title: Piston drive mechanism for reciprocating piston internal combustion engine
Inventor: SCHUBERT WENZEL
IPC: F02B75/32
Filed: 1981-07-28
Abstract: In the case of piston drive mechanisms of conventional reciprocating piston internal combustion engines the disadvantage exists that at the TDC, that is precisely in the area where the combustion gases exert the greatest working pressure on the system, the "pliability" of the piston head is theoretically nil. The object of the invention is a piston drive mechanism in which a short connecting rod emerges from the connecting rod pin bearing of the working piston, acts on an inclined, obtusely angled auxiliary connecting rod of the longer main connecting rod which is supported by its upper small end bearing in a slide guide arranged so that it can move up and down in the cylinder below the working piston, the longer end of the main connecting rod being connected by its lower bearing to the crankshaft journal. In this way without modifying the gas processing method a reciprocating piston drive mechanism is created which without modifying the thermodynamic process in the area of the TDC creates another pressure distribution and another component in the turning of the crankshaft and hence the drive mechanism. Increased torque is achieved starting at the TDC in the middle range, that is the connecting rod at the TDC receives a component which acts tangentially on the crank cycle. <IMAGE>

Title: Tennis racket
Inventor: KUEBLER SIEGFRIED
IPC: A63B49/02
Filed: 1981-09-09
Abstract: A tennis racket has a stretcher frame surrounding an area of springing between a racket head and a racket neck, in which stretcher frame bores or holes are provided to receive racket strings. The tennis racket is to be capable of being used for different types of stringing. The handling of the tennis racket process is also to be improved during the stringing, and in addition the loading of the strings during stringing and as a result of forces arising during play is to be reduced. This is achieved by a stretcher frame which has thirty-six approximately equally spaced holes in each frame side on each side of its longitudinal axis. With both normal stringing and diagonal stringing, one string is to pass through each hole. In addition, the hole spacing of the holes adjacent to the racket neck is greater than that between the other holes, which results in improved presentation of the desired diagonal or axis-parallel grid. <IMAGE>
