Title: Improvements in the scouring of cellulosic textile materials
IPC: D06L1/18
Filed: 1946-02-14
Abstract: Cellulosic textile materials are scoured by pre-impregnating them with a caustic alkali solution, holding them out of contact with steam for an interval of time sufficient for the caustic thoroughly and uniformly to penetrate the fibres and to partially solubilize size, pectins and natural sizes, and thereafter impregnating the materials with caustic alkali and steaming in the usual manner.  A penetrant may be added to the pre-impregnating solution which may be applied hot, and a detergent may be added to the final impregnating solution.  If desired, following the time interval and prior to the final impregnation, the materials may be washed.  The strength of the pre-impregnating solution may be from 1 to 8 per cent of NaOH and the time interval 1 minute to 8 hours, and the strength of the final impregnating solution from 1 to 8 per cent followed by steaming for 1/4 to 1 hour.  In an example, a herringbone twill is padded with a cold solution containing 4 per cent NaOH and 0.1 per cent of the penetrant "Nekal" (Registered Trade Mark), stacked for 1 hour or more and again padded with a caustic solution of the same composition applied hot.  The cloth is then steamed for 1/2 hour.  In a second example, unmalted poplin is impregnated with a solution containing 4 per cent of NaOH and 1 per cent of Nekal, allowed to stand for 1 hour and then padded with a similar solution at about 180 DEG  F., steamed for 45 minutes and washed with water at 160 DEG  F.

Title: Improvements in or relating to the detection of electromagnetic energy
IPC: G02F2/02
Filed: 1964-02-04
Abstract: 1,048,874. Lasers. SPECTRA-PHYSICS Inc. Feb. 4, 1964 [Feb. 7, 1963], No. 4724/64. Heading H3B. [Also in Division G1] The intensity of stimulated radiation at a first frequency from a laser due to transitions between two energy levels is varied by inducing transitions between a third energy level and one of the two energy levels corresponding to a second frequency by radiation at this frequency from a second laser, thereby altering the population of one of the two levels and altering the intensity of the emission at the first frequency. The output from a helium neon gas laser I is passed through filter 21 to remove all but the 33912 A line and then applied to a second helium neon gas laser II oscillating at a different frequency, i.e. 6328  corresponding to transitions between the 3S 2  and 2P 4  levels. The incident infra-red radiation on laser II causes transitions between the 3S 2  level and 3P 4  level, so reducing the population at the 3S 2  level available for lasing with the 2P 4  level and hence reducing the intensity of the 6328  line output. The reduction in intensity is detected by the photo-cell 31 and meter 32. The incident radiation may be the 11523  line corresponding to the 2S 2 -#2P 4  transition which has the effect of increasing the population of the 2P 4  level and again decreasing the intensity of the 6328  line falling on the photo-cell. Long wave energy may be converted to visible energy by using the long wave energy to cause a transition between the 3P 4  state and some other transition state thus altering the amplitude of oscillation of the 33912  line which in turn decreases or increases the population of the 3S 2  state thereby increasing or decreasing the intensity of the radiation at 6328 .

Abstract: 629,628. Velocity-modulated tubes. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. Feb. 20, 1947, No. 5005. Convention date, July 11, 1940. [Class 39 (i)] [Also in Group XL (b)] A thermal tuning member, such as plate 33 supported by bimetal 60, has portions extending into each of two resonators. When the bimetal is heated, as by electrical element 64, or by immersing the whole device in a temperature-controlled bath, the plate moves further into one resonator and out of the other, thus enabling the tuning of the two resonators to be equalized. The plate 33 moves in a slot in the dividing wall 29, which also carries the drift tube 27 and the feedback loop 57. The collector electrode 47 is insulated so that it acquires a negative charge and deflects the spent electrons to the wall of container 1. Cooling may be obtained by coil 3. The Specification as open to inspection under Sect. 91 comprises also replacing the bimetal by a single expansible element, or tuning the resonators without the use of plate 33 merely by immersing them in a bath, the temperature of which can be controlled from that of liquid air upwards. This subject-matter does not appear in the Specification as accepted.

IPC: B66B5/18
Filed: 1928-02-17
Abstract: 312,107. Schank, A., and Bittel, O. Feb. 17, 1928. Catch gear of mine-cage type.-A safety suspending appliance for lift cages &c. has a frame movable relatively to the cage and carrying the main brakes, the frame also carrying pilot brakes, which are normally kept out of action by triggers operated by a spring-pressed plunger on breakage of the winding cable, so as to cause the pilot brakes to be applied, the subsequent movement of the cage applying the main brakes. The cage b has uprights c on which a horizontal frame d slides. Brackets n on the frame carry co-axial rods o provided at their ends with brake shoes p and forming the pilot brakes. The pilot brakes are adapted to be pressed against the guides a by springs r but are normally retained out of action by pivoted bent levers s connected to a vertically slidable plate v. The cage is suspended from the winding cable by a frame b<1> bearing through a coil spring y on a leaf spring x mounted in a frame x<1> to which the cable is connected. When the rope breaks, the coil spring presses a plunger w against the plate v thus releasing the bent levers sand allowing the pilot brakes to engage the guides. As the cage moves downwards relatively to the frame, bent levers j pivoted to the cage push outwards wedge blocks i mounted between the main brake levers f and so cause the main brake shoes g to engage the guides and stop the cage.

Title: Quenching and purification of gaseous reaction products
IPC: C07C7/00
Filed: 1958-02-19
Abstract: <PICT:0847699/IV(b)/1> In a process where hydrocarbons are present at low partial pressures in the presence of steam and the gaseous effluent contains polymer and other emulsion-forming contaminants and is quenched to lower the temperature and remove such contaminants, the effluent is passed into the lower section of a quench zone having an upper and a lower section separated by means preventing entrained liquid passing from the lower to the upper section, contacting the effluent with quench oil in the lower section and water in the upper section and recovering cooled effluent free of emulsion-forming contaminants.  The quenching process is particularly useful for the effluent from a butene dehydrogenation process forming butadiene.  In such a process the effluent from reactor 2 may be at 925 DEG -1,250 DEG  F. and 2-10 psig.  It is cooled to 450 DEG -700 DEG  F. and passed into the lower section B of quench zone 7 where it is scrubbed with oil from line 16.  The oil may be saturated or unsaturated having an initial boiling point above the highest temperature in zone B.  The oil is circulated from the bottom of the zone back to the top with cooling, contaminated oil being removed by line 21 and fresh oil being added by line 15. The oil is passed to the zone at a rate of 350,000-900,000 lbs./hr. and a temperature of 140 DEG -230 DEG  F. The gas passes up to the upper Section A the two sections being separated by a screen 9 or a layer of Raschig rings or Berl saddles or merely a space.  In the upper section the gas is washed with water from line 10 to 90 DEG -200 DEG  F. fed at a water to feed weight ratio of 0,5-2 : 1. The water removed by line 11 passes to separator 12 where oil is allowed to separate out and is passed by line 14 to zone B.  The water is obtained by condensation of steam from the gases.
