Patent DE-1946029-A1 (DE)
Title: Demoulding threaded articles from rotary - injection moulding machines
Inventor: HAERTIG CHRISTIAN
IPC: B22D29/00
Filed: 1969-09-11
Abstract: Device is for removing threaded castings from a mould having hydraulic mould closure cylinders. A shaft rests in the hollow piston rod of each cylinder and projects by a plug-connection into the movable mould clamping plate. The other end of the shaft is connected by a coupling with the longitudinally movable rotary shaft of a stationary drive. This eliminates the use of unscrewing elements and cogwheels, thus speeding up the removal.

Title: Sausage skin end-closure - application device
Inventor: WINKLER BRUNO
IPC: A22C13/00
Filed: 1972-09-28
Abstract: Puckered sausage skin is closed at one end; it is made from an edible substance, cellulose or a thermoplastic synthetic material. The closure is constituted by the puckered end, this is drawn together by press. stuck, at least partially, with an adhesive in the puckered state and then pressed together again. The closure is cheap and does not require foreign bodies, such as adhesive tapes, metal hooks or tied threads. The closing process is effected by means of a tool in the form of pincers, it serves to grip and draw together the puckered end of the sausage skin. A metallic tube distributes the adhesive while the ends of the pincers press the gathers together. Finally, the pincers push the closure into the opening of the skin and are themselves withdrawn. The adhesive is made from physiologically acceptable prods., such as gelatine, starch, gum arabic, casein or collagen. The end closure should not be too solid as this would prevent the easy expulsion of the sausage meat.

Title: Carbon monoxide detection using semiconductors - with temp variation giving long term stability and methane detection
Inventor: EICKER HARTMUT DIPL PHYS DR RE
IPC: G01N33/00
Filed: 1973-03-17
Abstract: A method of determining the proportion of >=1 gas constituents in a gas mixture, esp. the CO constituents, utilises metallic oxide semiconductors which change their electrical resistance in the presence of reducing gases. The temperature of the metallic oxide semiconductor is periodically changed between two boundaries values, esp. an upper value 400 degrees and a lower value >-20 degrees C, and esp. at approximately room temp. This arrangement enables the high selective sensitivity to the presence of CO in the low temp. ranges to be utilised for detecting CO at the expense of other reducing gases, while the sensitivity in the higher ranges to CH4 and other hydrocarbons enables this end of the temp. range to be utilised for selectively detecting the presence of these constituents. The use of a periodically fluctuating temp. regenerates the semiconductor so that gases which have diffused into its surface do not modify its long term sensitivity.
