Title: Method of and apparatus for demodulating fsk signals
Inventor: FISCHER REINHARD DIPL ING
IPC: H04L27/156
Filed: 1982-05-24
Granted: 1985-01-17
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.

 ii) are defined in
 a) that each of the aforesaid sulphur atoms in the compounds R3-S-S-R and R5-S-H is bound to a carbon atom in an aromatic ring and
 b) that under prevailing splitting conditions a compound R3-S-H or R4-S-H released by the reaction of the compound R3-S-S-R4 and the compound R5-S-H exist substantially in their tautomeric forms HR min 3 = S, HR min 4 = S and HR min 5 = S respectively, or corresponding resonance-stabilized anion forms.

Title: Process for producing a ceramic fiber blanket
Inventor: YAMANAKA HIDEKI
IPC: D04H1/435
Filed: 1984-01-06
Granted: 1988-01-07
Abstract: A ceramic fibre blanket is prepd. by (a) preparing a laminar pile of ceramic fibres contg. 35-65 wt.% Al2O3, 35-65% SiO2 and less than 10 wt.% another metal oxide, and a lubricant; (b) superimposing a web of organic fibres on one or both sides of the pile; and (c) punching the resulting assembly with barbed needles, pref. using 50-200 barbed needles/cm2. The organic fibres allow a higher density of punching needles to be used, even in thin blankets (less than 5mm), without damage. The resulting blankets have much higher tensile strength, e.g. 1.5 kg/cm2 for blanket only 2.4mm thick, punched with 150 needles/cm3. Without the organic webs, fewer needles can be used, and max. tensile strength of a 6mm thick blanket was 0.35kg/cm2, attained using 20 needles. The organic fibres may be removed by incineration with the lubricant, or may be left in situ.
