Title: Manufacture of 2-alkyl-tetrahydrobenzselenazoles
Filed: 1937-06-22
Abstract: 2-Alkyl-tetrahydrobenzthiazoles and 2-alkyl-tetrahydrobenzselenazoles are prepared by causing an ortho-halogen-cyclohexanone to react with a thio-fatty acid amide or a seleno-fatty acid amide or a substituted thio- or seleno-fatty acid amide.  The compounds have the general formula <FORM:0497659/IV/1> where Y=sulphur or selenium, and R=an alkyl or a substituted alkyl group.  The reaction is preferably conducted at a raised temperature.  In examples: (1) o-chloro-cyclohexanone and thio-acetamide are heated together, and the reaction product treated with caustic soda, and the oil so liberated extracted with ether.  The residue on evaporation of the ether is distilled under reduced pressure to give 2-methyl-tetra-hydro - benzothiazole; (2) o - chloro - cyclohexanone, alcohol and seleno-acetamide are heated together, the reaction product is taken up in water and filtered from the precipitated selenium.  Caustic soda is added to the filtrate to precipitate the 2-methyl-tetrahydro-benzselenazole; (3) o-chloro-cyclohexanone and thio-propionamide are heated together and the product treated with caustic soda to give 2-ethyl-tetrahydrobenzothiazole.

The air pressure is indicated on a gauge 16 and actuates a contact 22 controlling a magnetic valve 23 which then admits compressed air into pipes 9c, 9d, 9e. The air pressures therein are indicated on gauge 16c, 16d, 16e and when compared with predetermined standard pressures, show the extent and direction of any misalignment of the platens. In other embodiments, Figs.3, 4 (not shown), one or two apertures are provided in the lower platen. In another embodiment, Fig. 8 (not shown), the aperture or apertures in the lower platen communicate with an annular or part annular groove or grooves in the upper surface thereof; this arrangement is used to allow for slight relative rotation of the dies.

Abstract: 1,260,936. Feeding sheets. METAL BOX CO. Ltd. 7 April, 1970 [9 April, 1969], No. 18309/69. Heading B8R. Sheets are separated from a pile 5, Fig. 2, and moved to feed rollers 10, 11 or bands by a plurality of suction nozzles 13 engaging the trailing end of the top sheet and carried by a head 8 on a mounting 15 having a part pivoted to move vertically under the control of counterbalance means comprising a piston 25 slidable in a pneumatic or hydraulic cylinder 16 to which fluid is supplied through a valve 30 and from which the fluid leaks slowly, so as to accommodate differences in height between the front and rear of the pile. Fingers 44 engage the front of the pile. The pile support 6 is raised when the front of the top sheet sinks below a certain level, by means actuated by a switch 31. A feeler 32 is oscillated on a fixed shaft 33 under the control of a cam 39. When the pile level sinks to a point too low for feeding to the rollers, the feeler moves over the stack and thus allows the cam roller 37 to drop sufficiently to close the switch. A blower 14 assists separation of the top sheet. In another form, Fig. 7, the piston is replaced by a screw 50 rotated by an electric motor 55 controlled by micro-switches 56, 57 actuated by raising and lowering of the blower 14 and a timing-switch 58 controlled by a cam 59 synchronized with the cam 39. A limit switch in series with the switch 31 prevents raising of the support 6 unless the head 8 is raised.
