Abstract: 1469161 Pulse-Doppler radar SIEMENS AG 16 April 1974 [16 April 1973] 01504/74 Heading H4D In a pulsed Doppler radar system of the kind comprising a plurality of sequentially sampling range channels connected in parallel after the detector, each channel comprises a Doppler filter DF, Fig. 1, following the range gate ES and including a storage circuit HS for holding the sampled amplitude, and either a high pass filter HP whose cut-off is at the maximum clutter frequency or a band pass filter whose lower cut-off is also at said frequency and whose upper cut-off is above the maximum pulse repetition frequency to be used. The pulse repetition frequency can then be varied, with corresponding variation of the sampling times, but without having to vary the frequency characteristics of the high pass or band pass filter. Each channel further comprises an amplifier VS, rectifier GR to convert the bipolar video to unipolar, a low pass post integration filter NT and a multiplexing switch AS operating in synchronism with the range gates ES to sequentially feed the channel contents to a display SG. To increase clutter rejection the range gate ES, storage circuit HS and filter HP may be replaced by two such triads in series, Fig. 7 (not shown), the second gate having a longer sampling time than the first and the second filter having a steeper lower cut-off gradient. It is shown that the output of the Doppler filter due to the gating &c. of higher order Doppler side bands, e.g. (nfp+f D ) as allowed by the extended upper extent of the filter, is the same as that due to the prior art gating of the first order side band f D  above.

Title: Improvements in cellulose esters and processes of producing the same
IPC: C08B3/12
Filed: 1945-01-22
Abstract: Cellulose esters of enhanced elasticity are made by treating cellulose with one or more monobasic organic esterifying agents in amount of 200 to 800 per cent of the weight of cellulose and one or more dibasic organic esterifying agents in amount of 0.125 to 22.4 per cent, in the presence of a substance in which the reaction product is dissolved or swollen.  Monobasic organic esterifying agents specified are acetic, propionic, butyric and lauric acids, and anhydrides and acid halides of such acids. Specified dibasic organic esterifying agents are adipic, succinic and sebacic acids, and the corresponding acid halides, as well as compounds of the formula. XOCCH2CH2(OCH2CH2)nCH2 CH2COX, in which X is hydroxyl or halogen and n is an integer preferably from 1 to 4.  The esterification may be carried out in the presence of catalysts, impellers, or organic bases.  Suitable solvents or swelling agents for the products are toluene, dioxane and acetone.  When an ester lower than the tri-ester is desired, it is preferred to hydrolyse the tri-ester. In a modification, the dibasic radical may be introduced prior to substantial esterification of the cellulose with the monobasic esterifying agent.  The products of the invention usually have from one or less dibasic acid radical per 20 glucose units, to one or less per 500 glucose units.  Examples are given in which (1) wood pulp is esterified with adipyl chloride and lauryl chloride in the presence of pyridine and toluene; (2) wood pulp is esterified with lauryl chloride and sebacoyl chloride in the presence of pyridine and toluene; (3) and (4) wood pulp is esterified with butyryl chloride and sebacoyl chloride in the presence of pyridine, dioxane and toluene; (5) wood pulp is esterified with caproyl chloride and succinyl chloride in the presence of pyridine and dioxane; (6) wood pulp is esterified with propionyl chloride and hexaglycol diacid chloride in the presence of pyridine and dioxane; (7) wood pulp is esterified with propionyl chloride and triglycol diacid chloride in the presence of pyridine and dioxane; (8) and (9) wood pulp is esterified with propionyl chloride and pentaglycol diacid chloride in the presence of pyridine and dioxane; (10) wood pulp is esterified with propionyl chloride and hexaglycol diacid chloride in the presence of pyridine and dioxane; and (11) cotton linters are esterified with acetic anhydride and sebacic acid in the presence of acetic acid and sulphuric acid.
