Title: Process and apparatus for separating benzol or benzine from mixtures containing dilute alcohol
IPC: C07C29/80
Filed: 1924-01-22
Abstract: 210,094. Stinnes-Riebeck Montanund Oelwerke Akt.-Ges., H. Jan. 22, 1923, [Convention date]. Alcoholic liquids, distilling; hydrocarbons, distilling.-In separating mixtures of benzol or benzine and dilute alcohol to obtain the hydrocarbons free from alcohol, or to obtain mixtures of the hydrocarbons with strong alcohol, the mixture is distilled until the boiling point commences to rise. The distillate is diluted with water to separate the hydrocarbon as an upper layer, and the aqueous alcohol is rectified. In the case of mixtures of benzol and dilute alcohol, the mixture begins to boil at about 65‹ C. and distillation is continued so long as the boiling- point is constant. The residue from the distillation consists, if the mixture contained only a small proportion of benzol, of dilute alcohol, if the mixture contained about equal quantities of benzol and dilate alcohol, of a mixture of benzol and strong alcohol, and if the mixture contains larger proportions of benzol, of benzol mixed in some cases, with water. The mixture from a vessel A passes into a heated column B. The vapours from the column pass to a condenser C. The condensate is mixed with water in a device D and separates into layers in a vessel E. The benzol is withdrawn at F. The dilute alcohol passes into a column G, and alcohol vapours pass from the top of the column to a condenser H. Strong alcohol withdrawn at J may be mixed with benzol withdrawn at F. In separating mixtures of benzine and dilute alcohol, vapours of benzine evolved below 100‹ C. pass to the con. denser C, and benzine of higher boiling-point is obtained together with water, from the base of the column G, and is separated in a vessel M.

Title: Improvements in or relating to method of and apparatus for making and apparatus caps for milk bottles and the like
IPC: B67B3/02
Filed: 1936-01-27
Abstract: 460,070. Making and applying closurecaps for bottles &c. GAMMETER, J. R. Jan. 27, 1936, No. 2521. [Classes 125 (ii) and 125 (iii)] Closure caps for milk bottles &c. are made from discs of contractible material, formed from a thermoplastic rubber derivative, e.g. a rubber hydrohalide film, which are superposed over the open end of the bottle, heated air being directed into contact with the marginal portion of the disc which is pressed around the mouth of the bottle to form overlapping portions which become adhesively interconnected and prevent accidental removal of the cap. As shown in Fig. 1, a strip of rubber hydrohalide film 13 is fed intermittently across an opening 11 in a bed plate 10 above the bottle A which is moved upwards so that its open end engages the strip which is then clamped on to the plate 10 by the descent of a stripper plate 16 spring- supported in a head 18. Further movement of the head causes a die 21 carried thereby to cut a disc from the strip 13 while a spring-supported presser member 24 within the head 18 engages the disc over the mouth of the bottle and heated air from jets 40 in a circular conduit 38 encircling the opening 11 play upon the marginal portion of the disc. When the marginal portion of the disc is softened, the supply of heated air to the jets 40 is cut off and the bottle is moved upwards against the action of the spring 26, an inflated air bag 28 within the head 18 engaging the marginal portion of the disc and crimping and pressing it around the mouth of the bottle ; the cold bottle causes the disc to contract and form a skirt tightly fitting around the mouth of the bottle, the overlapping portions 41, Fig. 5, of the skirt being adhesively connected together but not sticking to the walls of the bottle. The bag 28 is secured to a ring 29 and to a tube 23 sliding over the spring 26 and is supplied with air through a pipe 36. The usual paper disc 42 is provided for temporarily sealing the bottle when in use and a paper disc 43 may be adhesively secured to the outside of the closure over the mouth of the bottle subsequently to the cap-applying operation or these discs may be secured to the strip 13 in spaced relation. The outer paper disc may have a curved peripheral edge which projects slightly beyond the mouth of the bottle or the disc may be secured to the underside of the cap.

Abstract: 954,322. Pilot-controlled automatic volume control. FELTEN & GUILLEAUME FERNMELDEANLAGEN-G.m.b.H. Jan. 24, 1962 [Jan. 24, 1961], No. 2577/62. Heading H4R. In a carrier frequency transmission system in which a pilot frequency, within the signal frequency band, is transmitted to control the gain of intermediate amplifiers in the system and in which the signal may inadvertently contain components at or near the pilot frequency which may cause errors in the regulation of the gain of the intermediate amplifier, an additional control signal is transmitted at a frequency outside the signal frequency band and its amplitude modified whenever the energy transmitted at the pilot frequency deviates from the correct value and the variation of this control signal disables the regulating circuit in the intermediate amplifier. The preferred embodiment is a transmitter handling the signal frequency band 556 to 6056 kc/s. and comprising a filter 1 to eliminate any components at the control signal frequency, e.g. 60 kc/s., and a coupling circuit 2 which adds to the signal frequency a pilot signal at 4092 kc/s., and the control signal at 60 kc/s. which is applied to the coupling circuit via a switch 7<SP>1</SP> which is controlled. via amplifier 6 and relay 7, in accordance with the energy present at the pilot frequency in the transmitted output. The switch 7<SP>1</SP> may either switch the control signal off (or on) when the energy at the pilot frequency varies or the switching may be between two discrete levels of the control signal. At the intermediate amplifier the pilot signal is separated from the transmission by filter 13, amplified, and applied to a gain regulator R. The connection between the amplifier and regulator is maintained by contacts UI of relay U while the 60 kc/s. control signal is detected by the control circuit Z, absence of the control signal opening contact UI to disable the regulator R. In an alternative arrangement in which the control signal is switched between two discrete levels and the change in level causes operation of relay U an additional relay V is provided which, in the event of complete failure of the control signal, closes contacts VI and restores the regulator operation. Contacts UII and VII respectively disable and enable an alarm circuit whilst the control circuit is modifying the regulator operation, and contacts VIII operate an alarm signal to indicate failure of the control signal or circuit.
