Abstract: 141,680. Chantiers et Ateliers A. Normand. April 17, 1919, [Convention date]. Regulating compression. - In air compressors and other compressed air apparatus, explosions at starting and stopping due to the presence of lubricating oil are prevented by the use of relief valves held open by compressed air admitted by a valve actuated by a lever-operated cam ; the lever may be the eccentric shaft on which the needle and starting levers of a Diesel engine driving the compressor are pivoted. Mechanical, hydraulic, or electric means of transmission may replace the use of compressed air, and thermal or electrical motor control means may replace the starting handle. As shown, the motor control shaft 2 is provided with cams 31 15, respectively actuating valves 7, 13 in a distributing box 8. When the handle 1 is in the position shown, where the engine is being started by compressed air, a projection on the cam 3 depresses the valve 7 and allows compressed air from a reservoir to enter by a pipe 9 and pass by passages 10, 11 and pipe 17 to the relief valves, lifting their pistons 21 against spring pressure and allowing escape of air through the passages 19. When the engine is at rest, the valve rod lies between the projection 4, 5 on the cam, and the valve 7 is closed by spring pressure. With the handle in the vertical position, the valve rod is beyond the projection 5 and the valve 7 is closed; the cam 15 depresses the valve 13 allowing escape of compressed air from the pipe 17 through the passage 12 and port 16 to atmosphere.

Abstract: 1349231 Activating chemical processes; low temperature condition detecting device KOCKUMS MEKANISKA VERKSTAD AB 17 Feb 1972 [18 Feb 1971] 7442/72 Headings B1F and B1X Activation of a chemical process at a certain temperature is caused by a change in volume of an activation medium due to a phase transition of the medium at that temperature by allowing the change in volume of the medium to act on means separating the reaction components to allow contacting of the components. The activator medium is encapsulated in a wholly or partly elastic container. The invention can be used for indicating if foodstuff has been exposed to unsuitable time temperature conditions in freezing machines, where the indicator reactants comprise an enzyme, a substrate and indicator and a buffer, e.g. as disclosed in Specification 1,297,195 (see heading B1X). In Fig. 1, chemical 3 is brought into contact with chemical 5 by reducing the temperature to freeze the water 4 in plastic container 2 so that the container wall expands to break the glass wall 1. In Fig. 3, capsule 2 contains ether which is liquified by cooling causing plastic capsule 2 to contract thus enabling chemicals 3 and 5 to contact each other.
