Title: Improvements in record card controlled machines
Filed: 1954-01-14
Abstract: 747,373. Statistical apparatus. MAUL, M. Jan. 14, 1945 [Jan. 19, 1953], No. 1125/54. Class 106(1). A record card controlled tabulator provided with known group control for comparing group numbers of successive cards, the group number being located in a group data field, is characterised in that under the control of an analyzing device for special marks of particular record cards, e.g. summary cards, the group control device is shifted to group data fields of the special cards, these group data fields being located in a different position on the special cards from that of the regular cards, i.e. cards not having special marks. Fig. 2 shows a summary card S1 between two detail cards P1, P2 bearing different group numbers, and also a portion of the tabulator printed summary sheet showing the change of group number and summary totals. Referring to Fig. 1, cards are fed past brushes Sb, bI, bII. The brush Sb serves for detection of the summary card hole, the brushes bI analyze the value of the data representing areas for transmission to the tabulator printing mechanism which is of known form. The brushes bII co-operating with brushes bI feed the known group control device. If item cards of the same group are analyzed all group relays G will respond and will establish by means of their contacts gI, gII holding circuits, also a parallel circuit to the motor M will be established via contacts gIII so that when the cam-operated contacts nI open the supply to the motor will not be interrupted. When the brush Sb detects a summary card hole, the relay H is energized and actuates its contacts hI to hIV establishing a holding circuit, and by means of contacts hII the relay shifts the connections from the brushes bI via other plugging positions which have been set up previously, to the magnets D of the printing mechanism in accordance with the different arrangement of card S1. The connections to the group control relays G are shifted in a similar manner. Provided that the group control numbers read from successive cards are in agreement the relays G are energized actuating contacts gI to gIV, establishing a holding circuit for relay G and a circuit in parallel with cam contacts nl, so that the machine continues to run. If, however, the group numbers do not agree, one of the G relays will not respond and the supply to the motor M will be interrupted when cam contacts n1 open, thus stopping the machine for error indication. The same sequence will occur if the group numbers are in agreement but no summary card has been analyzed before. After analysis of the summary card and printing of a total, a group change will take place, if it does not, an error in the placing of the summary card is indicated and the machine is again stopped by interrupting the supply to the motor M. Another embodiment is described in which a second summary card detecting brush is used. Specification 674,572 is referred to.

Abstract: 977,001. Controlling burners. HONEYWELL CONTROLS Ltd. Nov. 28, 1963 [Jan. 11, 1963], No. 1278/63. Heading F4T. [Also in Division G1] An ultra-violet flame detection apparatus for a burner supplied with liquid and pulverized fuel comprises a first element 10a posi - tioned to respond to the flame G of the liquid fuel and a second element 10b positioned to respond to the flame H2 of the pulverized fuel. The elements 10a, 10b may be Geiger-Mueller tubes of the non-self-quenching type. The first element 10a is positioned behind the burner structure and receives radiation passing along an annular space E between a tube A for liquid fuel and an annular structure B for pulverized fuel. A zone H1 of unburnt pulverized fuel shields the first element 10a from the flame H2 of the pulverized fuel. The element 10b is positioned at one side of the burner structure. The Geiger-Mueller tubes are connected into an electrical circuit, Fig. 2 (not shown), including four lamps and two changeover switches, each tube operating one switch so that the lamps indicate the four possible flame conditions of the burner. When a burner installation includes an array of burners a small apertured plate. is provided between the second element 10b and the burner with which it is associated. The indications from the elements may be used to operate control action such as the opening or closing of a fuel valve or the starting or stopping of a pump or fan motor. The control means may be a computer for controlling a steam generating plant. The liquid fuel burner may be a pressure jet burner or a burner of the whirl chamber type. The pulverized fuel is fed tangentially to the annular structure B. A wind-box F supplies air under pressure and is provided with vanes causing the air to rotate.

Title: Manufacture of thymol
IPC: C07C39/06
Filed: 1944-01-25
Abstract: Thymol is made by treating a mixture of meta-cresol mono- and di-sulphonic acids, obtained by sulphonating meta-cresol and in which the proportion of the 6-mono-sulphonic acid is considerably larger than that of the 4-monosulphonic acid, with a quantity of propylene, or of a substance, e.g. propyl or isopropyl alcohol, yielding propylene under the conditions of reaction, sufficient to monopropylate substantially only the mono-sulphonic acids, desulphonating the sulphonic acids in the resulting reaction mixture to produce meta-cresol and a mixture of propylated meta-cresols, and, after the separation of meta-cresol, isolating thymol from the propylated meta-cresols.  Advantageously, at least 70 per cent of the mono-sulphonic acids in the mixture of meta-cresol mono- and di-sulphonic acids consists of meta-cresol-6 sulphonic acid, the mixture being made by sulphonating meta-cresol under defined moderately strong conditions, e.g. with 98 per cent sulphuric acid in a proportion of substantially 3 mols. of H2SO4 per mol. of meta-cresol at at least 80 DEG  C.  Other sulphonating agents may be used such as chlorosulphonic acid or fuming sulphuric acid.  The propylating agent may be applied directly to the sulphonation mixture before the sulphonation is complete.  Examples relate to: (1) and (2) sulphonating m-cresol with differing amounts of 98 per cent sulphuric acid and treating the cooled sulphonation mixture with absolute isopropyl alcohol with subsequent heating at 70-120 DEG  C., treating the product with steam at 140 DEG  C. to effect desulphonation and to distil a mixture of meta-cresol and propylated meta-cresols from which crystalline thymol may be obtained by further distillation and cooling the distillate; (3) sulphonating and propylating meta-cresol as in (1), using meta-cresol of which more than half has been recovered from a previous treatment, together with a mixture of isopropyl alcohol, water and some of the mono-propylated meta-cresols recovered from a previous treatment.

Abstract: 338,798. I. G. Farbenindustrie Akt.- Ges. Feb. 25, 1929, [Convention date]. Cellulose carboxylates.-Mixed organic esters of cellulose are prepared by treating cellulose with an organic acid or its anhydride, and the halide of another organic acid, in the presence of a tertiary base, the quantity of which is smaller than that which is equivalent to the acid and acid derivatives present. The acid radicals thus introduced into the cellulose molecule may be derived from lower and higher saturated and unsatured fatty acids and cyclic carboxylic acids. The products are readily soluble, and when mixed esters containing the acetyl group are prepared as described above, an after-treatment for attaining acetonesolubility is unnecessary. The products may be used for making artificial filaments, films, lacquers, &c. Examples are given describing the preparation ot (1) a cellulose acetate-naphthenate by treating cellulose with glacial acetic acid and naphthenic acid chloride in the presence of pyridine; (2) a like product obtained with the use of acetic anhydride instead of acetic acid; (3) a cellulose acetate-butyrate by treating cellulose with acetyl chloride and butyric acid in the presence of pyridine bases; (4) a butyric-cocoa-fattyacid ester by treating cellulose with butyryl chloride and cocoa fatty acid in the presence of pyridine bases.
