Title: Entering and securing of plug-in circuit module - using entry guide and captive pull-up and clamping screw
Inventor: DOERFLINGER KARL ING GRAD
IPC: H05K7/14
Filed: 1980-07-30
Abstract: A typical application is to mounting circuit modules in telecommunications equipment. In such installations the space available for mounting plug in components is usually very limited, which can make insertion and withdrawal difficult. The module (1) is initially entered by hand into the stationary receptacle (2) by constructing the latter to give a lead in. The module is pushed in until the fastending screw (4) makes contact with the end (3) of the corresponding tapped hole. The screw has a head which is in a slot in the module This slot makes the screw captive and at the same time allows some axial movement. The axial movement is such that when the screw first engages with the threads in the hole several turns have to be completed before the under side of the head bears against the face of the slot. Further turning then pulls the module home and makes the electrical connections (5,6,7,8). To disengage the module the process is reversed.

Title: Paper-making linked band mfr. - uses fixing and coupling wires for simple laying of adjacent coiled strands to form the band
Inventor: BACHMANN WOLFGANG
IPC: D21F1/00
Filed: 1980-12-22
Abstract: A fixing wire ranges parallel to the coupling wire over the width of the linked band, inserted into the free space before the coiled strand is inserted. After the coiled strand has been inserted, and fixed, the fixing wire is extracted from the coiled strand by the coupling wire. Specifically the fixing wire is made of metal. The flexible blade, to range into the free space in the coiled strand, has a central recess for a carrier bar, which is also recessed to be engaged by the blade and clamped in place by a holding bar and flexible buffer. More than two supply points deliver the coils through advance wheels and channels so that over two coiled strands are available at the laying point. The coiled strands are passed from their feed points to buffer stores, interlinked with each other, for the interlinked coils to be advanced to the laying point. The entry into the buffer store is at an angle to the outlet. As the layer moves along, edges bear against the coils to align them against each other with height adjustment for these bearing edges. The coupling wire can be separated from the coupling wire by heat. A filler insert can be provided within the coils, fitted while the coils are being developed, using a multifilament fed continuously where the coils are formed. Used in the mfr. of a linked band for a papermaking machine, etc. the process gives a structure where the openings of one coil do not obstruct the coils of the next strand laid.

Title: Compensation circuit
Inventor: SUZUKI TAKUYA
IPC: H04R3/00
Filed: 1981-07-02
Abstract: In summary, the invention provides the following: a circuit for compensating for the frequency characteristic of the microphone output variable, the arrangement being made in such a manner that a combination of a microphone element of the pressure-gradient type of construction with a proximity effect, represented by a rise in its low-frequency range sensitivity when the microphone element closely approaches a sound source, with another microphone element is provided, the latter microphone element belonging to the pressure type of construction and does not develop a proximity effect in order to cancel in this manner the occurrence of the proximity effect. An increment of the sensitivity of the pressure-gradient microphone in the lower frequency range due to the proximity effect is determined from the level difference between the output variables of these two microphones, and this increment is subtracted from the output variable of the pressure-gradient microphone in order to provide by this means a compensation for the proximity effect in the output variable of the pressure-gradient microphone.
