Title: An improved multi-colour printing machine
IPC: B41F3/30
Filed: 1947-03-14
Abstract: 622,380. Printing-machines. EDELS, A. March 14, 1947, No. 7193. [Class 100 (ii)] A multi-colour offset printing-machine, which can print on cylindrical articles, is constructed with an oscillating carrier c having a plate d in which a galley e is mounted, fitted with two differently-coloured blocks, by means of which offset impressions are printed on a surface i mounted on a turntable H carried by a sliding plate g moving over rails a<SP>1</SP> mounted on a base a. As the carrier c is moved from open position to the closed position shown in Fig. 1, the plate g is moved by linkwork, or other mechanism, from its right-hand position to the position shown, and during this movement the turntable h is rotated through a quarter of a revolution and is held in this position by pawls p mounted in spring-controlled arms q engaging a ratchet-wheel o on the turntable. This movement of the turntable is effected by a spring- raised pin m<SP>2</SP> acting on an arm of a cam l shaped like a Maltese cross, the pawls p being actuated to free the turntable shaft by a spring-pressed cam member r<SP>2</SP>. On the return movement of the carriage g due to opening of the type carrier c, the turntable is again rotated a quarter of a revolution in the same direction by the action of a pin m<SP>1</SP> on the cam l, the locking pawls being released by a cam r<SP>1</SP>. The pins m<SP>1</SP>, m2 are formed with sloping surfaces which permit them to be depressed when not required to actuate the cam l. The printing blocks rotate through half a revolution between the interval of printing a first impression and a second impression, so that they are arranged in reverse in the galley to ensure register of the second impression on the offset surface, from which surface one two-colour impression can be transferred to a cylindrical article at each complete oscillation of the carrier c. The machine may be arranged to print four colours instead of two.

Title: Anti-anemic substance and process of making it
IPC: A61K31/00
Filed: 1934-03-13
Abstract: An anti-an mia product is obtained by subjecting stomach tissue, which must include, in addition to the lining of the pouch or central section, stomach wall tissue other than the mucosa, to incipient self-digestion but preventing the digestion from continuing further, removing water and retaining the residue for oral administration. The fresh stomach tissue, which is preferably not allowed to remain after slaughter for more than 5-6 hours at a temperature materially above freezing, is washed and ground and self-digested at, for example, about 98 DEG  F. for 2-12 hours.  This self-digestion is effected under acid conditions, desirably with addition of acid to give a pH of 1-5,5.  The material is now dehydrated, the temperature being kept below 115 DEG  F.  Subsequent removal of fat with petroleum ether is desirable.  B vitamins such as those from wheat embryos, rice polishings or yeast, and iron salts, for example iron-ammonium citrate, may be added.  According to an example, whole hog stomachs are acidified with hydrochloric acid to give a pH of 4,5-5 and allowed to digest for 2-4 hours at 98-100 DEG  F.  The material is dried at a pressure of 0,2-0,5 ins., and a temperature below 100 DEG  F., defatted, and residual petroleum ether removed. Specifications 24505/09, [Class 81 (i)], 387,641, and 411,179 are referred to.
