Title: Facsimile receiver
IPC: H04N1/40
Filed: 1976-05-21
Abstract: 1532035 Facsimile EXXON RESEARCH & ENG CO 21 May 1976 [21 Aug 1975] 21163/76 Heading H4F A facsimile receiver includes a band pass filter 30 passing FM signals in the range 1500 Hz (white) to 2400 Hz (black) which attenuates noise outside this range. The filtered FM signals are differentiated 32 to produce trigger signals which set a monostable 34 having a fixed stable period. A detector 36 outputs a D.C. signal the magnitude of which vanes according to the ratio between stable and astable periods of the monostable output cycle. A stylus drive circuit is provided with contrast and brightness controls described w.r.t. Fig. 4 (not shown) and a scanning control circuit 42 which initiates scanning in response to an initial 2400 Hz burst, thereby eliminating false start up, is described w.r.t. Fig. 3 (not shown). The filter pre amp, differentiator and monostable are described w.r.t. Fig. 2 (not shown). Operation of the receiver is described with reference to the wave-forms of Fig. 5 (not shown) and filter characteristics of Fig. 6 (not shown).

Title: Process for the production of 2-alkyl-í¸-oxazolines and 2-aryl-í¸-oxazolines
IPC: C07D263/12
Filed: 1965-05-21
Abstract: 2-Alkyl-, 2-cycloalkyl- and 2-aryl-D 2-oxazolines are prepared by dehydrating the N-2-hydroxyalkyl carboxylic amide of the corresponding aliphatic, cycloaliphatic or aromatic carboxylic acid in the gas phase at 250-700 DEG  C. in the presence of a dehydration catalyst. The catalyst may be aluminium oxide or silicon dioxide which may be impregnated with a salt, e.g. an alkali metal phosphate, and the reaction may be effected under reduced pressure or in the presence of an inert gas.  Instead of employing an N-2-hydroxyalkyl carboxylic amide as reactant a salt of a carboxylic acid with a hydroxyalkylamine derivative may be employed. In the compounds prepared in the examples, the substituents in the 2-position are methyl, propyl, phenyl and tolyl.

Abstract: 1422105 Jet pulverizers FLUID ENERGY PROCESSING & EQUIPMENT CO 17 May 1974 22025/74 Heading B2A [Also in Division C1] Black powder viz. potassium nitrate, charcoal and sulphur, with optional additives e.g. wood flour is made in a mill system comprising a pair of curved jet pulverizers 10, 100 in series, the first 10 having a high pressure jet feed and the second a low pressure jet feed, the first pulverizer having an expanded downstack 20 and the second pulverizer an expanded upstack 106. Both pulverizers are of the known "tractrix curved" type. A relative humidity of 85-95% is maintained by injection at 46, 48 of a fine spray mist of water (0.01 to 10 Á) with automatic metering. The water is preferably at 70‹ to 100‹C. Potassium nitrate is supplied from a hopper 40. The charcoal is cooled e.g. with liquid air or nitrogen via a pipe 38 to increase its absorptivity prior to its passage from a hopper 30 into the mill; and slowed down as it goes through the downstack 20 where the potassium nitrate dissolved in the hot water spray is absorbed and adsorbed. Alternatively a coolant solution may be used instead of water. Material is exhausted along a duct 18 to a cyclone 28. Clean gas is exhausted from a filter 52 via a duct 54. Dust and separated solids pass into a receiver 58 are dropped on to a conveyor 62, compacted by a compactor 64 and are disintegrated and sieved at 66. Additives, e.g. wood flour, may be introduced either with the charcoal and sulphur or via a separate feed inlet. The material is fed to the second mill for polishing via hopper 114. Graphite is supplied to the mill via a hopper 118. The widened upstack 106 permits rolling and tumbling of particles without excessive grinding. The product is exhausted via duct 112 into a cyclone 122 and is discharged into a container 130. Both mills and all other components are grounded and the nozzles may be of nylon to prevent electrostatic sparking. In a modification all components are added to the mill 10 above the expanded downstack portion 20.

Abstract: 415,574. Earpiece attachments. MOLLER, 0. W., 9, Mimervagen, Djursholm, Sweden. Aug. 5, 1933, No. 22094. [Class 40 (iv).] Relates to attachments for the earpieces of telephone or radio receivers of the kind comprising a device for catching the sound produced by the receiver connected by a sound-conveying duct to a member adapted to be placed over the other ear. According to the invention, the sound-catching member is provided independent of the receiver in the form of a funnel with one or more outlet branches, said member being retained in the substantially vertical channel of the ear adjacent the ear lobe with the funnel portion at the top by the receiver when same is placed in position. As shown in Fig. 1, the funnel - shaped sound - catching device 9 is retained between the receiver 30 and ear E and has its outlet tube 8 connected by a duct 47 or 51 to a pipe 4 communicating with a parabolic cavity 2 in a member 1 adapted to be hung by a strap from the other ear. A head band 7 may, however, be provided and this may be used to conduct sound from the funnel 9 to member 1 in place of the duct 47 or 51. According to modifications, the funnel 9 may have more than one outlet tube and may be formed as or surrounded by a substantially parabolic member (Figs. 2, 3 and 8, not shown). The funnel may also be fitted with or integrally formed with a projecting arm adapted to enter the external ear so as to form additional means for holding it in position. Fig. 5 shows a further modification in which the funnel 9 is formed with an enlargement 24 adapted to conform with the inner shape of the receiver. The duct may be secured to the member 1 by forming the pipe 4 with a conical portion over which the end of the duct is slipped and afterwards pressed into a conical hole in the member 1.
