Abstract: 388,216. Making rubber goods from aqueous dispersions. REVERE RUBBER CO., 355, Valley Street, Providence, Rhode Island, U.S.A.-(Assignees of Gibbons, W.A.; 357, Park Street, Montclair, New Jersey, Hazell, E. ; 10, Sheridan Square, New York, and Keen, A. W. ; 129, Westervelt Place, Passaic, New Jersey, both in U.S.A.) Feb. 29, 1932, No. 6036. Convention date, March 11, 1931. [Class 70.] In a process for the manufacture of rubber filaments, in which latex is streamed into a coagulant, the latex extruded at the orifice is under an automatically controlled hydrostatic head thus giving a constant pressure of extrusion. As shown, Fig. 1, latex passes from tank 1 through strainer 2 into 5, by the aid of a vacuum in 11. The latex in 5 is stirred to remove air bubbles. Valve 10 prevents 5 overflowing and latex escaping. The vacuum is released and the latex allowed to flow through strainer 15 to one of two feed units. The latex passes through a rubber tube 17, controlled by a solenoid valve 18, and through strainer 24 into a constant pressure regulator 30, the head of latex therein being kept constant by the falling and raising of 30 coacting with spring 28, and, via mercury contact 22, with solenoid valve 18. The latex siphons from 30 into the manifold 38 and through nozzles 43. The flow through the nozzles is regulated by plungers 41, Fig. 2, the nozzle orifice for the production of rectangular threads being shaped as in Fig. 3. The hydrostatic head controlling all the nozzles may be regulated by raising all the regulators 30 by chain block 130. The nozzles may be lifted by rocking bar 44 to the dotted line position or adjusted independently. The latex issues from the nozzles into the coagulant, passes through the bath and the filaments are drawn over a glass spacer 49 by roll 50. The filaments pass under glass hook 53, Fig. 8, and are then washed by a water spray from 54. The filaments then pass through bath 60 containing, for example, ammonium hydroxide to neutralize residual acidity and to harden them, and are thereafter picked up by belt 84. The level of ammonium hydroxide in 60 is maintained constant by container 68 into which a supply is constantly pumped by the bulb 72 which is actuated by cam 75. The filaments on the belt while passing into the dryer are dusted with talc supplied from a hopper 91. In the dryer air is sucked by fan 98 through heating means 99, along the upper part of the dryer and through pipe 94 back to the circulating fan along the lower part of the dryer. The filaments are then passed through a revolving pipe 116 into a rotating basket 117 where the filaments are coiled up ready for vulcanization. An indicating system of coloured electric lamps controlled by mercury well 137 indicates the rate of flow of latex. Specification 214,615, [Class 70, Indiarubber &c.], is referred to.

Title: Blanker inhibit circuit in a radio receiver
IPC: H03G3/20
Filed: 1977-02-14
Abstract: 1525897 Interference suppression in radio receivers MOTOROLA Inc 14 Feb 1977 [25 March 1976] 06088/77 Heading H4L An AM receiver includes a stage 22 producing an AGC signal, a blanker circuit 32, 34, 20 for muting the receiver in response to received noise pulses, and an inhibiting circuit 12 responsive to the AGC signal for inactivating the blanker circuit when the received RF signals exceed a minimum value. In the embodiment described the AGC voltage decreases as the RF signal amplitude increases. With weak signals transistor 40 is conductive, the voltage applied at control input 36 is low, and amplifier 32 operates normally to transmit received signals to blanking signal generator 34. If the received signals exceed the minimum value, the AGC voltage falls below a threshold, 40 turns off, and the control voltage at 36 goes high which causes amplifier 32 to be inhibited. A diode 48 provides temperature compensation.

Title: Improvements in or relating to the preparation of manganese carbonyl hydride
IPC: C01G45/04
Filed: 1959-02-23
Abstract: Manganese carbonyl hydride is prepared by reacting manganese pentacarbonyl with hydrogen at pressures of 300-5000 p.s.i.g., preferably 500-2000, and at temperatures of 50-250, preferably 100-200 DEG C. for, say, 30 minutes to 4 hours.  To avoid decomposition of the manganese carbonyl the reaction may be carried out under carbon monoxide pressure employing a weight ratio of carbon monoxide to hydrogen of 1 : 1 preferably 1 : 3. The manganese carbonyl reactant may be employed as a solution or dispersion in a liquid inert carrier, e.g. white mineral oil, saturated aliphatic and aromatic hydrocarbons, ethers, diesters or silicone oils, specific examples of which are referred to. After reaction the pressure vessel is cooled and the gaseous reaction product vented preferably through a plurality of dry-ice cooled traps in which the manganese carbonyl hydride collects. Any product remaining in the residue in the vessel is isolated by purging the mixture with an inert gas, e.g. nitrogen, and thereafter passing the gaseous effluent through the plurality of cold traps.  Alternatively, when employing an inert liquid carrier which is immiscible with water, separation of the manganese carbonyl hydride may be effected by addition of water to the reaction mixture, followed by separation of the manganese carbonyl hydride by decantation of the aqueous phase, or by solution of the product into a water immiscible solvent, e.g. an ether or hydrocarbon.  Separation of the product may also be effected by vacuum distillation employing a reflux condenser to prevent distillation of solvent, or, when a solvent is employed which is liquid at the temperature of dry ice, by cooling the mixture to precipitate the manganese carbonyl hydride, which is isolated.

Title: Method for enhancing seismic data
IPC: G01V1/36
Filed: 1973-02-08
Abstract: 1392014 Seismic signal processing TEXACO DEVELOPMENT CORP 8 Feb 1973 [1 March 1972] 6177/73 Heading H4D The signal-to-noise ratio of digital seismic data representing time-aligned traces is enhanced by establishing a search window covering a time-portion of both a selected reference trace and several adjacent traces, detecting a signal with trace-to-trace coherence within the window, computing the coherent signal component associated with the reference trace, recording the component in place of the extant reference trace portion, and repeating the above steps for other windows and other selected reference traces. The aligned traces may be derived from stacked common-depth-point records, or from raw field traces recorded with common offsets between source and detector. In the flow diagram shown, the search window specified at 31 is centred on a trace R selected as the reference and takes into account expected dip. An adjacent trace X is cross-correlated with R by time-skewing it at 33 relative to R and computing at 34 respective correlation coefficients Ci associated with iterated values i of skew. A decision stage 35 ensures that the skew value does not exceed a preset limit (search lag), whereby multiples and other events having large moveouts do not cause spurious coherent alignments in the correlation process. The correlation peak is detected at 36 and the corresponding value of i is noted at 37. The coherent signal in the window, represented by a series of amplitude samples COHj, is computed according to the expression shown at 41, by averaging samples from trace R and adjacent traces A, B &c. The coherent signal component in the reference trace R is computed as K.COHj, where K is given by the expression shown at 42. This component is multiplied at 44 by a taper function, to emphasize samples at the centre of the window, and the tapered result is used at 45 as a noise-reduced replacement for the extant portion of trace R in the window. By subtracting the coherent signal from the trace R signal at 43 a noise signal is obtained. By iteration other windows are selected and processed, and other traces are selected in turn as the reference trace. The noise-reduced and noise signals may be separately recorded on chart plotters, cathode ray tube plotters or line printers.
