Title: Improvements in evaporators for steam generators operating according to the loefflersystem
Inventor: BELL ALAN
IPC: F22G5/16
Filed: 1954-12-03
Abstract: 772,814. Direct contact steam boilers. FOSTER WHEELER, Ltd. Oct. 21, 1955 [Dec. 3, 1954], No. 35123/54. Class 123(2) In a Loeffler boiler wherein a major proportion of steam which has been highly superheated in a furnace is used to generate saturated steam in an evaporator, the remainder being delivered as the boiler output, and the saturated steam is dried and circulated to the superheater by means of a compressor, the superheated steam at about 1000‹F. passes from an inlet header 15 disposed in the evaporator drum 10 through a nest of tubes 12 in indirect heat exchange contact with the water in the drum and enters a header 13 at about 650‹F. with some 20‹F. superheat. About 9/10 of the desuperheated steam flows from the header 13 directly to the evaporator outlet 22 through a pipe 14. The remainder is directly injected into the water in the drum through ejector nozzles 16 which ensure a flow of water over the tubes 12. The steam-water mixture from the nozzles flows into centrifugal separators 18 whence the steam passes to the outlet 22 through chevron driers. 20. With this arrangement the steam drying apparatus has to deal with the generated secondary steam but with only a small proportion of the primary steam so that its bulk may be correspondingly reduced. In modifications, the primary steam injected into the water is pre-cooled in separate tubing and circulation in the drum is promoted by feedwater nozzles or by convection circulation between a drum containing the desuperheaters and a superposed drum housing the steam-drying apparatus.

Abstract: Phosphorylated propylene polymers are prepared by reacting a propylene polymer with phosphorus trichloride and oxygen, and then hydrolysing the product.  The reaction may be effected in solution or dispersion, e.g. in excess phosphorus trichloride or aromatic or chlorinated hydrocarbons.  The phosphorylated polymers may be used to bond crystalline polyolefins to metals, either by laminating or as a primer when applying crystalline polyolefin coating compositions. Examples describe the preparation of phosphorylated polymers from stereo-regular and amorphous polypropylenes.ALSO:Metal substrates may be coated with crystalline polyolefins using as primer a phosphorylated propylene polymer containing phosphonic acid substituent groups.  Specified metals are steel, aluminium, copper and tinplate, which may be given conventional pretreatments, e.g. sand blasting, phosphating and chromating. Specified polyolefins are polypropylene, polyethylene, ethylene/propylene copolymers, copolymers of ethylene and propylene with other olefins, e.g. butene-1, ethylene/propylene block copolymers and alloys of stereoregular polypropylene with polymers of isobutylene and 4-methyl pentene-1.  The coatings may be applied by dipping or spraying, using organic solvent solutions or dispersions of the polymers, flame spraying; electrostatic spraying, airless atomization, hot melt and fluidized bed techniques.  In examples steel and aluminium sheets are coated with (1, 2 and 4) phosphorylated stereoregular polypropylene or (5) phosphorylated amorphous polypropylene, followed by one or more topcoats of stereoregular polypropylene, the phosphorylated polymers being prepared by reacting the polypropylenes with phosphorus trichloride in the presence of oxygen and hydrolysing the product.

Title: Method for separating extract of hops into soft resins and hard resins
IPC: C12C3/08
Filed: 1969-07-14
Abstract: 1,241,896. Distillation of hop resins. BLUE STAR CHEMICALS. 14 July, 1969 [17 July, 1968], No. 35297/69. Heading B1B. [Also in Division C6] Extract of hops is subjected to molecular distillation by conveying it under a vacuum of 0.01-0.00001 Torr. as a thin film on a wall heated to a temperature between 80‹ and 200‹C. and facing a cold wall. The hops soft resins are collected at the lower end of the cold wall as a yellow distillate whereas the hard resins descend along the heated wall as a tacky green-black mass. The flow of hard resins is assisted by the addition of polyglycol of very high molecular weight (at least 500), polyglycol and glycerol ether, or polypropylene-ethylene glycol copolymer, in which the hard resins are at least partially soluble. The heated wall may consist of an internally heated vertical tube surrounded by a helical wire for conveying the extract/hard resins from top to bottom and this is surrounded by a water cooled wall, the inner diameter of which is slightly larger than the outer diameter of the heated wall. Humulones in the hop extract may be isomerized prior to the molecular distillation, and traces of essential oils and residual solvent driven out by a preliminary distillation at a temperature of 40-100‹C and 0.01-1 Torr. pressure. Alternatively, partial isomerization takes place during the molecular distillation.

Title: Method of dynamically equalizing the gain of seismic signals
IPC: G01V1/24
Filed: 1968-07-24
Abstract: 1,210,456. Seismic prospecting. MOBIL OIL CORP. 24 July, 1968 [28 July, 1967], No. 35334/68. Heading H4D. An electric signal A is generated from a recorded seismic signal, there is derived from signal A a gain control function C representing a smoothed absolute value of the seismic signal, and the instantaneous amplitude of the seismic signal is adjusted by an amount related to 1/C. In an embodiment the output of rectifier 22 is fed to a delay line 24, for smoothing over an interval T. The weights introduced by rheostats 28 may correspond to a uniform impulse response, a triangular one, or a ramp, Figs. 3 to 5 (none shown). A voltage C from amplifier 30 is applied to a divider 32, the other input to which is applied a voltage V proportional to a desired "static" gain. Gain control function D, proportional to V/C, is applied to circuit 42 to multiply the signal from head 44 which is spaced by a delay T/2 from head 18, and the multiplier output is recorded by head 46. The delay for head 44 may be other than T/2. The smoothing may alternatively be effected by an integrating amplifier, Fig. 6 (not shown). Means to reduce a "truncation" error are discussed. Each seismic trace may be similarly equalized. The invention reduces gain variations other than those due to earth strata. The analogue arrangement may be replaced by the programming of a digital computer.
