Title: Automatic sewing machine pattern control
Inventor: HIROTA KUNIO
IPC: D05B19/10
Filed: 1981-03-05
Abstract: Pattern data for the automatic sewing machine allows manual selection of at least two blocks of pattern information units from one store, to be transferred into a second store to be held in the sequence of input. The second manual control uses the values of the temporarily held data to give modified position data to be used as control signals to execute the pattern, coordinated in time with the needle movement. The system allows patterns to be built up, to create letters or symbols and the like, giving easy adjustment for positioning and spacing. It also allows a positive stop action in the event of a thread break, and return the needle and fabric to the position where the thread broke to pick up the pattern.

Patent DE-3203711-A1 (DE)
Title: Flap valve for pipes, in particular for heating and/or ventilation nozzles in motor vehicles, and a method for the manufacture of such a flap valve
Inventor: HEUSER EDGAR
IPC: B60H1/00
Filed: 1982-02-04
Abstract: A flap valve for pipes, in particular for heating and/or ventilation nozzles in motor vehicles, has a flap which can be pivoted about an axis aligned transversely to the longitudinal axis of the pipe and the surface area of which corresponds approximately to the internal cross-section of the pipe. Such a flap valve is characterised by a combination of the following features, some of which are known per se:   a) the flap, which is composed of plastic, is formed integrally on the pipe, which is composed of the same material; b) a film hinge, which simultaneously forms the swivel joint of the flap, is used for the integral connection between the flap and the pipe; c) in the open position, the flap forms part of the wall of the pipe.   A flap valve of this kind can be manufactured from plastic in a simple manner and in a manner which saves materials, e.g. by injection moulding. The effort and costs involved in assembly are eliminated almost completely due to the integral design of the flap and the pipe. In the closed condition, the flap forms a good seal and, in the open position, does not form any hindrance whatsoever to the inflow of the flowing medium. The manufacture of such a flap valve can be made particularly simple and advantageous if a circumferential groove corresponding to the contours of the flap is made in the wall of the pipe, preferably in one single operation during the manufacture of the pipe, e.g. by injection moulding, such that the wall of the pipe at this point has a considerably smaller wall thickness, and if the wall of the pipe is then cut through along the groove, with the exception of that part of the groove which is intended for the film hinge.
Patent DE-3204849-A1 (DE)
Title: Long-term heat or cold accumulator with integrated heat exchanger
Inventor: HELMBOLD WALTER DR
IPC: F28D20/00
Filed: 1982-02-11
Abstract: Long-term accumulators for heat or cold require extremely low coefficients of thermal conductivity  lambda , in order for the losses to remain small. Such low  lambda  values can be achieved with fibrous or granular insulating layers as soon as the pressure is reduced (Smoluchowski effect). The smaller the mean free path length of the gas atoms or molecules between the fibres or grains of the insulating material, the lower the requirements placed on the vacuum. Temperature compensation and its consequences are possible by means of increasing pressure. The present patent claim covers pressure-controlled accumulators which by means of stipulating the mean free path length of the gas in the cavities of the insulating material permit individual wall parts of the container to be used selectively as heat exchangers without there being a need for the pressure wall of the accumulator to be penetrated by a heat exchanger. In the pure case of an accumulator, the vacuum-tight skin of the accumulator is at ambient temperature in common with the heat-exchanging part of said skin.
