Title: Sausage meat buffer device - which compensates for excess supply by twin piston assembly cutting off pump motor
Inventor: SCHNELL KARL
IPC: A22C11/02
Filed: 1973-12-13
Abstract: A buffer device between the pump and a filling machine of pasty substances, such as minced sausage meat, consists of a cylinder with a double piston which is displaced if the capacity of the pump exceeds that of the filling machine and has a boss on the piston rod extension. This actuates a switch and cuts off the pump motor. Compressed air returns the twin piston rod if the mismatch is remedied and cuts in the pump motor. Twin piston eliminates any risk of the compressed air or oil in its contaminating the filling material, or that the later blocks up the air system.

Abstract: The elements to be tested, are a microphone, loudspeaker, sender/receiver and their connections and contacts. The fault detector is a voltmeter, or an ammeter, or both combined. When one type of operation is changed to another, the last type of operation functioning is automatically tested, so that when the sending push-button is pressed down, the receiver is automatically tested, and the microphone circuit is automatically tested upon push-button release. The elements can be tested while in use since each important component and its leads are provided with an appropriate fault detector and indicator. An optimal surety of working is thereby given especially as used in aircraft.

IPC: G01N27/62
Filed: 1974-06-10
Abstract: Measuring the hydrocarbons concn. in a gas such as air and determining those hydrocarbons which exceed a predetermined threshold value utilises flame ionisation detection the air being supplied to the combustion gas flame of a first flame ionisation detector, in which the total of all the hydrocarbons present is measured electrically. when the total concn. in this first detector exceeds the threshold value, a partial stream of the air is conducted through a chromatograph column, and then into the flame of a second flame ionisation detector, where the concn. of the individual hydrocarbons is separately measured. Pref., the bled portion of air is continuously conducted through a metering loop, from which it can be conducted by an inert carrier gas through the chromatographic column into the second detector. Method is useful in pollution protection, in particular to enable any sudden increase in atmospheric pollution to be detected, so that its origin can be identified.
