IPC: A61M5/31
Filed: 1925-09-21
Abstract: 240,189. Haselmeier, W. Sept. 20, 1924, [Convention date]. Syringes.-In a syringe, for use more particularly in blood-transfusion, having two nozzles l, m, Fig. 5, to be connected by flexible tubing to needles inserted into the donor and the recipient, the nozzles form part of a collar i rotatably mounted on an extension g at the end of the syringe body, the extension g communicating with the barrel of the syringe through a bore h with which either of the nozzles l, m can be made to register. To ensure proper registration of the nozzles l, m with the bore h, the movement of the collar i may be restricted by stops so that one or other of the nozzles is operative when the collar rests in a stopped position. In this construction, as shown in Fig. 2, the obturator f of the syringe has a raised semicircular part p which engages a stop q on the collar. A modification is described in which a third nozzle, permitting admixture of the blood with chemical reagents, is provided. The Specification as open to inspection under Sect. 91 (3) (a) describes a modification in which the rotation of the collar i is unrestricted, its operative positions being shown by spring stops, and in this construction, as shown in Figs. 11 (Cancelled) and 15 (Cancelled), the extension g terminates beyond the collar i in a disc s. A forked pin t secured at one end to one of the nozzles l rests between the collar i and the disc s and is, formed with a slit u to engage a pin v on the collar. The pin t carries a flat spring w having an aperture x which engages a central pin y on the disc s and having also a pin z adapted to engage in hollows formed on, the disc s at points corresponding to the alignment of one of the nozzles l with the bore h. With this construction also, an additional nozzle may be provided. This subject-matter does not appear in the Specification as accepted.

Title: Process for the manufacture of low-carbon metals and alloys
IPC: C21C7/00
Filed: 1926-10-05
Abstract: 260,232. Nilson, G. E. R. Oct. 22, 1925, [Convention date]. Extracting.-In a process for the production of low-carbon iron of the kind in which molten ore is reduced by means of a high-silicon alloy, the manufacture of the high silicon alloy is carried out in two steps, (1) producing a relatively high carbon alloy by the reduction, in the presence of suitable fluxes, of a silicate slag, rich in metal oxides, obtained as a by-proluct m the manufacture, by the silico-thermic process, of a low carbon or metal alloy, and (2) melting this alloy with carbon and silica to obtain a high silicon alloy containing not less than 15 per cent of silicon, this reducing alloy being added while in the molten condition to the previously melted ore. For example, in the production of low carbon ferro-manganese, a charge of slag rich in manganese, obtained in the silico-thermic reduction of a manganese ore, is smelted with coke in an electric furnace to produce ferro-manganese rich in carbon and poor in silicon. This ferromanganese is then reduced with silica and coke, and, in the molten condition, is added to a melted charge of manganese ore, coke and quicklime. To facilitate reduction, aluminium silicate with additional carbon may be added to the charge in the formation of the high silicon alloy. The ore may be reduced by means of carbon to the lowest form of oxide before adding the silicon alloy.

Title: Improvements in or relating to devices for the selective opening of electric circuit-breakers protecting installations
IPC: H01H71/10
Filed: 1945-09-24
Abstract: 602,625. Protective cut-out systems. THEUNISSEN, F. J. M. Sept. 24, 1945, No. 24764. Convention date, Jan. 25, 1944. [Class 38 (v)] A protective system comprises a general circuit-breaker 1, 2, mechanically connected to a number of branch circuit-breakers a, b, &c., so that upon a heavy overload, or a shortcircuit on a branch circuit, the corresponding branch circuit-breaker only opens after the general circuit-breaker has opened. Upon overload, the contact lever 3 is moved by the coil 9 counter-clockwise about pivot 4 to open contacts 1, 2, so allowing spring 12 to rotate a bar 11 about pivot 22. Meanwhile, the lever 13 of the circuit-breaker of the faulty branch is moved up by the branch coil 17, so that the lever 13 and the bar 11 co-operate to cause latch 14 to trip. the branch circuit-breaker. A ratchet 7 engages the end 6 of lever 3, the return of which, under the action of spring 10, is retarded by a dashpot 8, until released by a nose 5, to ensure that the general circuitbreaker does not reclose before the branch circuit-breaker opens. Alternatively, the inertia of the general circuit-breaker may be relied on to.produce this delay. A limiting resistance R may be connected across the contacts 1, 2, to maintain the supply to the other circuits. Overloads within the capacity of the branch circuit-breakers are disconnected by thermal devices acting on the latches 14. The Specification refers also to reclosure of the general circuit-breaker by the opening movement of the branch circuit-breaker.
