Abstract: 1,194,143. Photographic camera shutters. ERNST & WILHELM BERTRAM. May 21, 1968 [June 29, 1967], No. 24241/68. Heading G2A. An exposure control circuit for a photographic camera shutter, the opening and closing of which are each effected by electromagnets 4, 10 has the current supplied to each electromagnet reduced to zero after each electromagnet has operated. In one embodiment, Fig. 1 (not shown), switch contacts (5), (6) are opened when the opening and closing shutter blades are reaching their end position, thus opening the circuits to the respective electromagnets. In the alternative embodiment shown, each electromagnet is connected in series with a condenser, 13, 14, the charging current of which is of such a magnitude as to enable the electromagnets to operate. Each condenser has a shorting resistor 12, 14 of such a value that the charge of the condenser may be fully dissipated between exposures, but forms an insignificant current drain upon the battery 1 during exposure. Switch 2 is closed by the actuation of the shutter-release and is returned to an open position by the shutter. A photo-resistor 7 controls the charging of a condenser 8 according to ambient illumination, a bi-stable circuit 9, e.g. a Schmitt-Trigger, firing when condenser 8 has reached a predetermined voltage to cause actuation of electromagnet 10. Brief time exposures are obtained by connecting terminal 11 to the battery, and arranging a contact 3 to open before contact 2 on operating the shutter-release; on releasing the shutter-release, contact 3 returns to its closed position, thus operating electromagnet 10 to close the shutter which then opens contact 2.

Title: Extrusion process for collagen casings
IPC: B29C48/10
Filed: 1965-06-11
Abstract: An edible sausage casing comprises cohered tendon colagen fibrils and from 5% to 20% by weight of gelatin relative to the weight of the dry collagen solids.  The collagen fibrils may be encapsulated in a matrix of gelatin and the casing may form a translucent hyaloid structure.  Preferably, the collagen fibrils lie generally parallel to the surface of the casing, which may be in a shirred condition. The sausage casing is made by extruding a continuous fragile tubular body from a fluid mass of acid-swollen tendon collagen, containg gelatin in the proportion of 5% to 20% by weight relative to the weight of the dry collagen solids, into an aqueous coagulant solution containing an inorganic salt, preferably ammonium sulphate.  Suit ably the collagen solids content in said fluid mass is greater than 2.5% by weight.  The coagulated body may be subsequently subject to hardening and washing, the wall cracking.  The dried casing may then be shirred, and is preferably then heat-cured.  This treatment comprises storage for about eight hours at a rising temperature bringing the casing material from room temperature to about 80 DEG C. It is then maintained at 80 DEG C. for some 16 hours more, which completes the heat curing.  The ultimate moisture content after heat curing is preferably 10% to 30% by weight.  To maintain the desired moisture content for stuffing, the re-humidified casings are preferably packaged in hermetically sealed containers of metal foil. If a small amount of formaldehyde is added to the hardening or plasticizing solution, the heat curing treatment may be omitted.
