Abstract: 1,060,011. Conveyers for flat articles. TELEFUNKEN PATENTVERWERTUNGS G.m.b.H. March 26, 1965 [April 22, 1964], No. 12947/65. Heading B8A. A switch-point in a conveyer for flat articles, e.g. letters or documents, comprises a switch blade 9 controlled by electromagnets 2, 3, the articles, after leaving a trough 1, being directed by the blade 9 into a trough 6 or 7. The blade 9 (also Fig. 3, not shown), comprises a non- rigid tongue 12 mounted in a guide web 8 and secured between two ferromagnetic material plates 10, 11. The free ends of the plates bear against the web 8. On cores 4, 5 of the electromagnets (Fig. 4, not shown), are energizing windings D 4 , D 5  connected in series to a direct voltage U 1 . Attraction windings A 4 , connected in series with counter-energization windings G 5 , are connected to an impulse voltage source U 2 . Alternatively, this source may be connected to windings A 5 , G 4  also in series. Operation. Assuming the blade 9 is lying against the core 5 and that the windings D 4 , D 5  are energized; if a letter or document in the trough 1 is to be directed into the trough 7 a signal transmitted by an allocation circuit (not shown) causes connection of the pulse source U 2  to the attraction windings A 4  and the blade is moved to core 4. Simultaneously with the energization of the windings A 4 , demagnetization of the core 5 results from energization of the windings D 5 . To return the blade 9 to the core 5 the pulse source U 2  is connected to the windings A 5 , D 4 . In a modification, Fig. 5 (not shown), the counter-energization windings are dispensed with.

Abstract: 266,951. O'Callaghan, M. May 27, 1926. Butter.-Cream, which has undergone fermentation, is converted into a modified creamy substance, and butter can be made therefrom, by the following process. An alkali or alkaline substance such as lime or sodium bicarbonite is added to neutralize acid and to assist in the separation of nitrogenous matter, and, after heating or pasteurizing, the liquid is then treated in the bowl of a centrifugal separating-machine with a current, jet, or spray of water which' may have been acidified and which is introduced on to the inner surface of the column of cream after it has been partly rid of nitrogenous matter by the action of the machine. At the stage immediately prior to that wherein the cream would assume somewhat the condition of butter a current of sweet milk is introduced, and, after thorough mixing of the mass, the reconstituted creamy substance is produced. If, however, it is desired to obtain butter, the whole or a part of the sweet milk is replaced by a current or spray of very cold water..

Saliva passes down a central tube 54 and may be drained off through a valve 82. The breath passes out through a valve 56 having very small holes 57 to prevent the ingress, e.g. of sea water into the apparatus. The outlet pipe may be closed if desired by a screw operated valve. The baffles 50, 51 may be replaced by a single set of baffles connected only to the central tube 54 (Fig. 1 not shown). In this case a pipe communicating with the condensing chamber and projecting upwardly into the pipe 27, acts as a saliva trap. Other arrangements comprise a single longitudinal baffle (Fig. 12, not shown), and a number of circular corrugated baffles providing a vertically sinuous path (Fig. 4, not shown). The condensed moisture may be collected in the cup 20 only or an additional cup 80 may be provided. Drain cocks such as 81 are provided on the condensing cups. The valve 56 may be replaced by a valve comprising a sleeve surrounding the tube 27 and having external longitudinal flutings providing, with an enclosing tube, long narrow discharge passages. In use the cup 20 is enclosed in a canvas bag strapped to the body and the tube 27 communicates with a mouthpiece fitting over the mouth and secured by a strap passing round the face and head.
