The reaction may be effected at a temperature up to 100‹ C. in an aqueous medium, preferably containing a water-miscible solvent, or in a two-phase system. Examples are given. The products are useful as antioxidants (see Divisions C3 and C5). Intermediates of the third formula above in which X denotes a benzothiazolyl sulphide radical are obtainable by reacting a phenol of the formula with one molar equivalent each of formaldehyde and 2-mercaptobenzothiazole under acid conditions. A number of phenols which may participate in this reaction are specified. Intermediates of the third formula above in which X denotes an N,N-dialkyldithiocarbamate residue are obtainable by reacting a compound of the formula with carbon disulphide.

When the gun is fired, gas pressure passes from the barrel 15 along conduit means 51, 50, 52 and 53 to cause the collapse of the toggle 35, 37 and compresses the springs 44, 61. The bolt 29 collects a cartridge 28 from a magazine 14 and positions it in the firing chamber when returning under the influence of the springs. The toggle can be relased manually by a lever 70, Fig. 6, and the bolt 29 can be moved rearwardly by a rod 72, Fig. 1. In a modification a cam 73, Fig. 6, is urged against a pin 36<SP>1</SP> of the toggle to collapse the latter. This is effected by pressurized gas from the firing chamber which is passed to a passage 75 in the frame via a passage 76, to force against a rod 74 of the cam 73. In another modification a screw 39<SP>11</SP>, Fig. 7, is provided and serves to adjust the under-centre toggle position. In a further modification a frame 10<SP>111</SP>, Fig. 8, is provided with a surface 39<SP>111</SP> which is engageable by a link 37<SP>111</SP> of the toggle to locate the latter in an over-centre position.

Abstract: 1469118 Measuring gas concentration electrically MINNESOTA MINING & Mfg CO 31 Dec 1974 [2 Jan 1974] 56172/74 Heading G1N The concentration of carbon monoxide in a atmosphere is measured by a detector comprising a housing 2, Fig. 1, open to the atmosphere, containing a sheet 15 of poled pyroelectric material, selectively coated on both sides with facing layers 16, 17 of conductive material. The alternate layers 16 on the front surface of sheet 15 are coated with a catalyst 21, e.g. platinum black, which causes the CO to combine with atmospheric oxygen and the resulting increase in temperature produces opposite electrostatic charges on opposing layers 16, 17 which are integrated, to indicate the CO concentration, and integrated again, to indicate the total amount of exposure to the gas. The integrators, formed as printed circuits on a card 22, are connected to alarms which operate at predetermined levels. The auxiliary layers 16 on the rear surface of sheet 15 provide automatic compensation for changes in ambient temperature. To facilitate the chemical action, the temperature inside housing 2 may be initially raised by a heating element, not shown. The sheet 5 is mounted on a backing card 19 to minimize vibration, and is shielded from atmospheric hydrocarbons by a charcoal filter 9.
