Title: Organic compounds which contain uretdione groups and blocked isocyanate end groups
IPC: C07C67/00
Filed: 1976-01-21
Abstract: 1488631 Uretdione derivatives BAYER AG 21 Jan 1976 [24 Jan 1975] 02295/76 Heading C2C [Also in Division C3] Organic compounds containing uretdione groups and blocked isocyanate end groups are prepared by converting an organic polyisocyanate into an intermediate product containing uretdione groups and free isocyanate groups and reacting this intermediate product with a blocking agent which is monofunctional towards isocyanates. The intermediate product is suitably prepared by dimerizing an organic diisocyanate in the presence of a tertiary phosphine as catalyst. Suitable blocking agents are secondary or tertiary alcohols, oximes, lactams, phenols, N - alkylamides, imides, imidazole or alkali metal bisulphites. In a typical Example (1) tolylene-2,4-diisocyanate is dimerized in the presence of tri-nbutylphosphine and the dimer is then reacted with #-caprolactam. The organic compounds may be used in the preparation of polyurethanes (see Division C3).

Title: Improved method of and apparatus for dehydrating wood and wood products
IPC: F26B25/00
Filed: 1948-01-26
Abstract: 655,064. Treating wood. HUDSON, M. S. Jan. 26, 1948, No. 2298. Convention date, Feb. 26, 1945. Addition to 655,062. [Class 140] [Also in Group XIII] In a modification of the apparatus for drying wood as described in Specification 655,063, which is in turn a modification of apparatus described in the parent Specification, the mixture of water vapour and drying medium is received from the drying chamber 107 by a complete condenser 109 which condenses the vapours to liquid phase. The liquids are then separated in a separator 110, the drying medium being collected in a tank 111 whence it is returned to the evaporator 108. Drying medium is supplied to the evaporator from storage (not shown), through line 112 and valve 113 to line 114 which leads to a pump 115 and line 116. Heat is supplied to the evaporator by steam-heated tubes 131 and cooling water is supplied to the condenser 109 through line 135. The pump 115 recirculates drying medium and water condensate formed in condenser 109 drains to the separator through line 127 and may then be drained to waste by opening threeway valve 139 to line 140, the valve 139 being then opened to line 141 to drain any organic condensate to the tank 111. The pump 115 is now stopped, the lines 114 and 116 closed and when the evaporator reaches the boiling point of the organic drying medium the drying operation may be started. Valves 142 are opened to introduce drying medium from the evaporator 108 to the drying chamber 107 through lines 143 and valves 144 are opened into the vapour header 145 which leads into lines 120, 147 to the condenser. The return tank 111 is heated by steam coils 154 and its liquid level may be gauged by a sight glass 155, photo-electric cells 156, 157 operating to control the pump 115 electrically so that when the liquid reaches the level of the upper cell the pump operates until the liquid reaches the lower level. The separator 110 also works automatically, electrode pairs 165, 166 being disposed therein. These electrodes complete circuits to the valves 158, 161 when immersed in the water layer being separated, which acts as a conductor. The condensate drains continuously but if the interface level rises, valve 161 is closed so that only water is discharged and the interface level falls. When it falls below electrodes 166, valve 161 opens again to discharge organic condensate to tank 111. A vacuum period may be imposed after the drying to recover organic material from the outer layer of the wood.

Title: Improvements in and relating to sheet control arrangements
IPC: G03G15/04
Filed: 1970-01-20
Abstract: 1,236,182. Feeding sheets. RICOH K.K. 20 Jan., 1970 [1 Feb., 1969], No. 2664/70. Heading B8R. A sheet control arrangement, e.g. for controlling the relative positions of an original sheet and a copying sheet in a duplicator before they are superimposed, comprises sensing means, e.g. a microswitch 4, for detecting leading and trailing edges of a first sheet 25, means, e.g. rollers 6, 13, for driving a second sheet 26 into superimposed relationship with the first, this driving means being actuated by control means responsive to the sensing means detecting the leading edge of the first sheet, the control means also being responsive to the sensing means detecting the trailing edge to cause a subsequent sheet to halt in a predetermined position which is varied by a means, e.g. rollers 8, 14, responsive to the sheet feed speed to obviate misalignment of the superimposed sheets. The first sheet 25 may be fed by rollers 2, 3 along a path 1, its leading edge actuating the switch 4 to actuate, after a time lag, a solenoid 16 which attracts a member 15, e.g. of iron, on a lever 12, thus causing rollers 6, 13 to engage the second sheet 26 which is therefore fed along path 5 to meet the first sheet 25 at the gap 1c. The trailing edge of sheet 25 causes the switch 4 to de-activate the solenoid after a further delay so that the next sheet 26, delivered by feed means 17, is engaged by compensating rollers 8, 14. Rollers 2 and 6 are driven by the same D.C. motor 7 and the difference between the voltage from a potentiometer 10 and the voltage driving motor 7 is used to drive the compensating rollers 8, 14 via a motor 9 which is mechanically connected to the potentiometer. Thus, a variation in feed speed actuates the compensating rollers 8, 14 until the mechanical coupling alters the potentiometer voltage to match that applied to the feed motor 7. The leading edge of a subsequent sheet 25 then repeats the operation.

Filed: 1958-01-28
Abstract: 836,078. Electrolytic production of protective anodic coatings on iron or steel. CONTINENTAL OIL CO. Jan. 28, 1958, No. 2862/58. Class 41. A protective coating is formed on an iron or steel object by subjecting it at least once to successive cathodic and anodic treatments in which the cathode: anode time ratio is greater than one in an aqueous electrolyte of pH 4 or more, and of which the cations are selected from the metals of S.G. less than four of Groups I and II of the Periodic System, so that the object is first pickled by evolved hydrogen and then oxidized to form a coating of ferrous and ferric hydroxides, whereafter the coating is converted to ferric oxide. Suitable anions are hydroxide, dichromate chloride, bromide, nitrate, permanganate, sulphate, phosphate. Iron salts of weak acids, e.g. organic acids, may also be included in the electrolyte which preferably is maintained at pH 4-12 and a concentration of 0.1-1.0 N while the applied E.M.F. is 1-10 volts and the current density at the object is 0.1-1.0 amps./sq. inch. The second electrode may be a carbon rod. Typical electrolysis is continued for 5 minutes using cycles consisting of 3 seconds as cathode and 2 seconds as anode. The electrolytic coating, which may be first dyed, may be oxidized either by heating in air or by treatment with a solution containing hydrogen peroxide or by bubbling oxygenenriched air or ozone through the electrolyte after the current has been turned off. If sodium hydroxide or lithium nitrate electrolytes are employed, golden conductive oxide coatings are obtained. Gun barrels and other gun parts may be protected by the process and the protective films dyed black. Automobile bodies and frame may be " undercoated " by the process.

Title: Data handling system
IPC: G06F9/00
Filed: 1966-01-21
Abstract: 1,122,590. Transistor pulse circuits. C. P. CLARE & CO. 21 Jan., 1966 [10 March, 1965]. No. 2871/66. Heading H3T. [Also in Division G4] A pulse generator 142 (Fig. 2) is included in a device including a plurality of register stages 112, 114, 116 for receiving random signals on a plurality of inputs and issuing sequential signals on a corresponding plurality of outputs (see Division G4). When any stage is set, a positive potential on a status conductor 146 energizes a winding 148 to close contacts 149 whereby a positive potential is applied to the generator 142 to make it operative. The positive bias applied to the emitter of normally non-conductive transistor 182 causes capacitor 194 of a timing circuit comprising elements 190, 192, 194 to be charged until the base of transistor 182 is driven positive with reference to its emitter whereupon transistor 182 becomes conductive and causes winding 170 to be energized and associated contacts 172, 174 to be closed and opened respectively. The positive potential is thereby connected to conductor 144 for resetting a or the set stage 112, 114, or 116. The capacitor 194 now begins to discharge through the base-emitter circuit of transistor 182 and resistor 186. In addition the opening of contacts 174 removes the inhibiting bias applied to base of transistor 180 and its base therefore becomes positive with reference to its emitter and discharge also takes place through this transistor. The impedance of this discharge circuit is varied by resistance 196 which determines the time interval required to discharge capacitor 194 to the point where conduction through transistor 182 is terminated. Transistor 182 then becomes non-conductive and winding 170 de-energized. Variable resistance 196 thus determines the on-time of the pulse. If a position potential is still applied through contacts 149 (i.e. another stage is set) the positive potential through contacts 174 and resistances 198 and 200 terminates conduction through transistor 180 and, through elements 190, 192, reinitiates charging of capacitor 194. Variable resistance 190 therefore determines the off-time between pulses.
