Patent GB-918744-A (GB)
Title: Improvements in or relating to the production of higher alcohols
Filed: 1961-09-15
Abstract: Higher alcohols (molecular weight up to 500) are prepared by reacting a C1-C8 saturated monohydric alcohol selected from aliphatic primary or secondary alcohols, or cycloaliphatic alcohols, with ethylene in the presence of a free radical reaction initiator at 50-400 DEG C., and at a pressure between 50 and 3000 psig. for 0.5-10 hours, in the absence of iron-containing materials.  The reaction may be carried out in the presence of copper, nickel, zinc, or alloys of these metals and may be in a reactor lined with "Monel" (Registered Trade Mark), glass "Pyrex" (Registered Trade Mark), silver, or "Teflon" (Registered Trade Mark).  The alcohol may be methanol, ethanol, or isopropanol.  Methanol produces mainly primary saturated alcohols; the product from ethanol contains more than 50% secondary alcohols; tertiary alcohols are produced from isopropanol.  The free radical reaction initiator may be actinic radiation, or a C1-C12 organic peroxide or hydroperoxide, or hydrogen peroxide, which are used in amounts of 0.05 to 5 grams per litre of alcohol.  Examples of such initiators are di-t-butyl peroxide, and cumene hydroperoxide. Specification 708,254 is referred to.

Title: A method of, and apparatus for, making bags from tubing of thermoplastic or thermoplastic-coated material
Inventor: FINKE ARNO
IPC: B29C65/18
Filed: 1954-11-16
Abstract: 762,264. Making bags. WINDMOLLER, A., and HOLSCHER, F. Nov. 16, 1954, No. 33218/54. Class 94(2). [Also in Group VIII] In the manufacture of bags from tubing of thermoplastic or thermoplastic-coated material, the tubing is cut transversely into bag lengths which are fed in succession to a movable sealing device having a series of bag sealing stations, the rear end of a bag length is heat-sealed at each sealing station, and the leading end of each bag is then detached from the sealing station and the bag delivered. As shown, tubing 3 is cut into lengths by cutters 5, 6 and the cut lengths are fed by belts 8, 9 between a rotary cylinder 10 and an endless band 11, the rear end of each length being gripped against an electrically heated bar 12 by a cam-operated gripper rail 13 ; transfer of the tube lengths to cylinder 10 is assisted by suction orifices in the cylinder or by air blown from an external source. During its travel with cylinder 10, the rear end of each tube length is seamed to form a bag by heat from bar 12 and then cooled by the heating current being switched off and/or coolant being passed through bar 12. After leaving band 11, each other bag is retained on cylinder 10 by suction or an external air jet, its rear end is released by gripper 13 and its front end gripped by cam-controlled grippers 17 on a second cylinder 16, cylinder 10 being circumferentially grooved to accommodate grippers 17. Cylinder 16 delivers the bags onto an intermittently-moving conveyer 24; or, where the bags are made of stiff material, they may be deposited in upright position side-byside.

Abstract: 786,369. Refrigerating. PRESSED STEEL CO., Ltd. Nov. 23, 1955, No. 33543/55. Class 29 In a compression refrigeration system defrosted by the "hotgas method, the refrigerant vapour is heated by water at atmospheric pressure, which is itself heated by electrical or other means. In a first embodiment, Fig. 1, the hot gas line 19 leads from the outlet of the compressor 10, is in heat exchange with a liquid trap in the suction line 17, has a coil 22 immersed in a water tank 23 and is in heat exchange with a defrost water drain 25 and drip tray 24 before connecting with the evaporator 16. A valve 20 in the line 19 is opened'to initiate defrosting. The water tank 23 is open to atmosphere, losses due to evaporation being recovered from defrost water draining into the tank, and the water is heated by an immersion heater 28, which may be energized continuously, subject to the control of a thermostat 29 operated in response to the temperature of the water. In a second embodiment, Fig. 2, the hot gas line is not put in heat exchange with the water tank 23 which is instead utilized to evaporate any liquid refrigerant entering the suction line 17 to the compressor during defrosting. Entrance of refrigerant to a by-pass pipe 32 in the suction line is controlled by a valve 31 opened with valve 20 on initiation of defrosting, the by-pass leading to the coil 22 immersed in the tank 23 and back to the suction line. Means are provided by which the water in the tank is prevented from exceeding a fixed level, thus keeping the pressure atmospheric. Specification 764,736 is referred to.

Abstract: 176,472. Godfrey, A. Dec. 2, 1920. Heating by electricity. - In an oxygen metalcutting apparatus, a separate stream of cutting oxygen passes through a pipe 3 and a coil 5 arranged in an electrically-heated oven 1, Fig. 1. From the coil 5, the oxygen passes through a cock 6 and reducing valve 8 to a pipe 10, which passes through the oven and may be coiled therein. The pipe 10 is connected by a flexible pipe 11. to the cutting burner. Pressure gauges 7, 9 indicate the gas pressure on both sides of the reducing valve 8 and a thermometer 12 indicates the oven temperature which may be controlled by hand or by a thermostatic device. In another arrangement shown in Figs. 4 and 5, an electrical heating device is clamped to the oxygen pipe 14 or the oxygen and fuel gas pipes supplying tha metal cutting burner. The heating device comprises brass or copper plates 13 formed with side channels in which are disposed heating elements consisting of mica plates 16 wound with resistance wire 17 and arranged between mica sheets 18, 19. The heating elements are enclosed by an iron plate 20 and the whole device is cased with asbestos in a fibrebox 22. The temperature is indicated by a thermometer placed in a recess 32 and is regulated by a thermostatic device onmprising an expansible block or fluid operating a spring or gravity controlled plunder 24. The plunger 24 engages at the limiting temperature a pin 25 on a crank 25<a> operating a pointer needle 26 and so moves an insulated electrical contact 27 on the pointer needle out of contact with an adjustable electric contact 28 on the dial plate 29, thereby breaking the heating circuit.

Title: Spectrum analysis with the aid of time resolved spark spectra and apparatus therefor

Filed: 1957-11-01
Abstract: 873,515. Spectrographs. BARDOCZ, A. Nov. 1, 1957, No. 34202/57. Class 40(3) In a method of spectrographic analysis in which material to be tested is caused by a spark discharge A to emit light, the light is directed on to a rotating or swinging mirror M, whereby light arising during an initial period of the discharge and comprising primarily background and spark lines is directed into the spectrograph entrance slit S2 over a first path Bl, L1, B3, and light arising during a later period of the discharge and comprising primarily arc lines is directed into the spectrograph over a second light path B2, L2, B4. The two spectra are caused to appear side-by-side on a photographic plate, the background spectrum at a suitably selected wavelength serving as a standard against which lines of the arc spectrum may be compared. The energy for the discharge is provided by a rectifier circuit T, V1, C, the spark being initiated by firing a thyratron V2 which causes the upper and lower sections of a controlling spark gap G to break down in sequence and connect capacitor C across the analyzing gap A. Correct timing of the discharge in relation to the movement of mirror M is effected by a photocell 1 which receives light from a lamp H when mirror M is in a predetermined position and produces a positive-going triggering pulse for the grid of the thyratron. An amplifier for the output of the photo-cell may include a phase shifter to permit precise setting of the time of discharge. Reference is made (without giving details) to the provision of an automatic control for the phase shifter operated by a photo-cell measuring the amount of light directed into the first path B1, L1, B3. The Specification describes a second embodiment, Fig. 2 (not shown), in which rhombuses B1-B4 in Fig. 1 are replaced by prisms and plane and concave mirrors.
