Title: The new fashioned shoe 80
Inventor: KLAMA HANS JOACHIM
IPC: A43B17/00
Filed: 1981-02-02
Abstract: Shoes are no longer to be able to be worn down unevenly. The ever-increasing repair costs will be reduced. The new shoe will be worn twice as long. In today's shoe, the inner sole and outer sole are a homogeneous part. The prepared shaft is added. In this case, exchange of the shoes from right to left is ruled out due to the one-sided shape. With fashioned shoe 80, the inner sole becomes the independent inlay sole with complete congruence with the outer sole (see diagram, sole view). This means that the new inlay sole, which adheres well but is easily removable, always remains with the foot whereas the outer sole (with shaft) can be changed as desired. Shoes are now worn right and left.     1) No more uneven heels, no more worn-down shoes; 2) only the bottom parts of the shoes are ever changed. Now the inside of the shoe and the inlay soles can also be aired and cleaned in a much improved manner. Fungal diseases will be reduced; 3) Fashioned shoe 80 shoes do not have to be unattractive or more expensive than conventional shoes; but they will bring great comfort to the feet of millions of people. e

Title: Outer door of sound-proofing design
Inventor: PRIMUS ILLO-FRANK DIPL ING DR
IPC: E06B9/17
Filed: 1981-03-17
Abstract: Doors are always a weak point in the sound-proofing of enclosed spaces. In protective spaces of machines, there is often insufficient room for mounting a double door, since the inner door necessarily has to open inwards. A combination of an outward-opening outer door (10) with a sound-proofing roller blind (13) arranged on the inside of this outer door is therefore proposed. The actuating mechanism (14) for the roller blind is arranged between the door plane and the roller-blind plane for safety reasons. <IMAGE>

Title: Device for sealing roller-blind casings, having a through-opening for pulling band, with respect to draughts
Inventor: WOLF GUENTHER
IPC: E06B9/17
Filed: 1981-04-28
Abstract: The device described is used, in the case of roller-blind casings with pulling band - opened to the front -, to prevent the resulting through-draughts, and thus the heat exchange in winter. The design of the mechanism is achieved such that, on actuation of the pulling band, the flap (5), which has a sealing effect in the rest position, is slightly raised and the pulling band can run freely. The parts described are adjusted in assembly such that they are adapted to the conditions (unevenness/"air duct" projects slightly beyond the wall, etc.). This results in an absolute sealing of the through-opening for the pulling band.
Patent DE-3118198-A1 (DE)
Title: Switch/capacitor filter
Inventor: HAUG KARL DR ING
IPC: H03H19/00
Filed: 1981-05-08
Abstract: The invention relates to a monolithically integrated switch/capacitor filter for time-discrete signal processing, amplifier, capacitors and a clock-controlled transistor switch being used. Previously, operational amplifiers have been exclusively used which required relatively large area and thus also a large amount of power. It is therefore proposed to use an isolating amplifier with the gain of one in order to avoid these disadvantages and to increase the signal frequency to be processed. Figure 2 shows a basic chip for a switch/capacitor filter according to the invention. <IMAGE>

Patent DE-3121444-A1 (DE)
Inventor: FISCHER REINHARD DIPL ING
IPC: H04L27/14
Filed: 1981-05-29
Abstract: Method for demodulating FSK signals in which zero crossings of the FSK signals are detected and processed further. A FSK demodulator including an address-generating logic and a memory connected to the address-generating logic. The FSK signals are delivered to the input side of and control the address-generating logic. At a system clock frequency, the necessary address sequence is supplied to the memory for reading out a pulse reply from the memory for each zero-crossing of the FSK signal. In the memory are stored time-sequential values of a pulse reply having a given duration which emulate the output of a digital non-recursive transversal filter having lowpass transfer characteristic upon an input pulse of given duration. The address generating logic supplies a definite counting address to each zero crossing on the input side which is not yet assigned to another zero crossing. The counting address sequentially assumes all sequence values for the given duration which are necessary for reading out the pulse reply from the memory and which last sequence value assumes a rest value after the completion of the read out process. Data read out from the memory during a given system clock period is summed up.

Title: Threaded seal for screwed connections
Inventor: FERCH ALOIS
IPC: F16B33/00
Filed: 1981-06-13
Abstract: The invention proposes a threaded seal for a screwed connection, in particular for metal fittings for fluid media, such as industrial valves, heating valves and the like. On one threaded part (1) of the screwed connection (1, 2) to be produced there is arranged an annular groove (4) which is cut into the thread, runs transversely to the axis of the screwed connection (1, 2), is open towards the corresponding second threaded part (2) to be screwed and has a rectangular cross-section. The annular groove (4), the depth of which is greater than the thread depth, accommodates a sealing ring (5) which consists of a thermoplastic polymer such as, for example, polytetrafluoroethylene. The walls of the sealing ring (5), the profile of which corresponds to the shape of the groove, rest on the walls of the annular groove. When the screwed connection (1, 2) is produced, the threaded part (2), to be screwed in, cuts the thread into the inner or outer circumferential surface of the sealing ring (5). The annular groove (4) - relative to the rotational axis of the threaded part (1) on which it is provided - is arranged eccentrically such that its depth - in accordance with the extent of the eccentricity - has a minimum at one point (6) and a maximum at the point (7) opposite the latter. The width of the sealing ring (5) assigned to the annular groove (4) changes constantly between minimum and maximum in correspondence with the shape of the annular groove. <IMAGE>
