Title: Improvements in or relating to frequency calibrating arrangements
IPC: G01R27/32
Filed: 1962-02-19
Abstract: 991,633. Frequency calibrating arrangements. SOC. AUDIOLA. Feb. 19, 1962 [Feb. 20, 1961], No. 6407/62. Heading G1U. [Also in Division H4] A method for providing a frequency reference mark on an oscillograph used in apparatus carrying out frequency analysis derives the marks from the "zero beat" between the frequency of a reference oscillator and the frequency of the wobbulator used to provide the frequency sweep. In the method the zero beat, once derived, must be detected and subsequently filtered, and then applied to a trigger circuit which supplies the marking signal. In apparatus for determining, say, gain as a function of frequency in a given circuit under test 2, a varying frequency from a wobbulator 1 is applied to the circuit, the output from which after detection is applied to an oscilloscope 7. In order to provide reference marks on the oscilloscope trace, the signal from the wobbulator is added to that from a reference oscillator in unit 13 and the added signal containing beat information is detected (in unit 4) and amplified in a selective amplifier 24 and then passed to a level detecting stage 26. This stage is set so that only the signal which occurs when the wobbulator and reference oscillator are at the same frequency, and thus amplified to the largest extent, is transmitted. The marks thus produced are added to the signal from the apparatus under test and so displayed on the oscilloscope at the appropriate reference frequency positions. Conventional circuitry for carrying out these operations is explained (Fig. 13 not shown), and the method may be used for locating electrical signals, representing phenomena under investigation, accurately in a frequency spectrum (Fig. 14 not shown). The Specification discusses the resolution of marker pulses theoretically.

Title: Improved apparatus for cleaning the ends of coated elongated articles such as containers or cans
IPC: B08B9/087
Filed: 1942-05-12
Abstract: 558,794. Wiping coated articles. ABBEY, A. (Crown Cork and Seal Co., Inc.) May 12, 1942, No. 6445. [Class 95] An apparatus for cleaning the end surfaces of elongated articles such as containers or cans, e.g. for wiping excess coating material from the neck ends of internally coated containers, comprises a conveyer wherein the articles are supported in non-upright position, and a cleaning apron adjacent the path of movement of the articles having a surface upon which the end surfaces of the articles are wiped and cleaned, said apron being shifted to present fresh surfaces to successive articles. Waxcoated containers 10 leave a draining chamber 13, and are carried on conveyers 12, 15 past a heated surface 22 which removes any drops of wax which may be present on the necks of the containers. The containers, in a horizontal position, then roll down a chute 20 into the wiping machine, where they are rolled along tracks 26 by endless belts 32, 33. During this, movement the container ends are wiped by a driven fabric sheet or apron 50, which may be fed continuously or intermittently, and which passes a shaped guide bar 53, and which may pass through a tank of a cleaning liquid, e.g. a wax solvent. In the modification shown in Fig. 9, the containers 110 are carried by cradles 111 through the wiping machine, each container having an aligned plunger assembly 151 moving, along tracks 153, 154, in unison therewith. The wiping apron 178<SP>1</SP> is slowly led from the supply roll 178, over rolls 182, 182<SP>1</SP>, to the rewindina roll 197. As the containers and plunger assemblies move jointly across the apron, on opposite sides thereof, the cam rail 232 projects the plungers forwardly to the position shown in Fig. 11, so that the neck is wiped. In this modification, rotation of the containers is unnecessary.

Title: Production of styrenes and other products
IPC: C07C4/00
Filed: 1945-03-15
Abstract: Styrenes and their nuclear substituted derivatives are produced by heating asym. diaryl paraffins, and their nuclear substituted derivatives having at least 2 carbon atoms in the paraffin chain, to at least 350 DEG  C., and passing them through a finely-divided siliceous catalyst, preferably a hydrated aluminium silicate, with a contact time of .004-.4 sec.  Inert diluents such as water vapour, hydrocarbons, e.g. benzene or toluene or fixed gases, e.g. nitrogen or carbon dioxide, are preferably present in a molar ratio to the diaryl paraffin of 1 : 2 to 25 : 1.  Initial materials include asym. diphenyl, phenyl tolyl, ditolyl, phenyl xylyl, tolyl xylyl, and dixylyl ethanes, a ,a -diphenyl, phenyl tolyl, phenyl xylyl, ditolyl, and tolyl xylyl propanes, and their nuclear halogen or hydroxy substituted derivatives, and hydrocarbon oils containing the same as obtained by distilling benzol still residues.  These may be preheated and passed through a steel, silica or other converter containing the catalyst at the desired temperature of 350 DEG  to about 600 DEG  C. or even higher.  Those catalysts with higher ratios of silica to alumina are most active.  They may be formed into pellets, preferably of not more than 5 mm. greatest diameter.  The contact time is computed on the assumption that the catalyst is 50 per cent voids and neglecting pressure drop and volume increase. Unconverted materials may be recirculated.  Pressure may be atmospheric, reduced or elevated.  The catalyst is reactivated with air, preferably mixed with steam, at about 590-650 DEG  C.  In examples: ditolyl ethane with benzene, water, nitrogen or carbon dioxide in molar ratios of 1 : 12.2, 16, 11.85 or 12.1 respectively is treated at between 440 DEG and 475 DEG  C. using contact times of .08, .033 and .10, p-methyl styrene and toluene being recovered; di-(m-xylyl) ethane with 23.7 molar proportions of water is treated at 390 DEG  C. with a contact time of .065 sec. giving dimethyl styrenes and m-xylene; while di-(chlorphenyl) ethane and di-(dichlorphenyl) ethane with water at between 630 DEG  and 650 DEG  C. and contact times of .1-.4 sec. give chlor- and dichlorstyrene respectively and chlorbenzene or o-dichlor-benzene.  Specification 569,465 is referred to.
