Title: Improvements in Masks for Protection Against Asphyxiating and other Gases.
Inventor: GRAVEREAUX RENE LOUIS
IPC: A41D13/11
Filed: 1916-03-22
Abstract: 103,901. Gravereaux, R. L., and Martin, C. March 22, 1916. Respirators; protectors and shields. - A mask for protection against asphyxiating and like gases is formed from several layers of muslin or the like connected together by sewing, and is so shaped as to lie against the forehead and to pass under the chin. Several such elementary masks, each impregnated with a different chemical, may be superposed and sewn together. The masks are fitted with transparent eye-pieces. The Figure shows a mask consisting of two elements a, b stitched together, an opening for the eyes being covered by a transparent flexible sheet f. The mask is held in place by elastic bands h, i and a non-elastic band j. No fastening-devices or knots are employed. In a modification, the transparent sheet f is replaced by a sheet of rubber carrying two transparent disks.

Abstract: 856,877. Feeds for rolling-mandrels. DALMINE S.p.A. Feb. 8, 1957 [April 28, 1956], No. 4355/57. Class 83 (4). In a pilger rolling-mill with reciprocating rolls, the mandrel carriage A, Fig. 1, is moved for feeding, stripping, return, &c. by a rotary nut 4 which is axially fixed in the machine frame B and engages a threaded rod 3 attached to the mandrel carriage A. The nut is driven at high speed by a motor 5 for fast forward and return motion, the drive including a magnetic brake 8 to prevent overrunning. For slow feeding and stripping operations the nut is driven by a motor 6 through a reduction gear 7 and an electromagnetic coupling 9. In a modification a single motor may drive the nut through change-gear means.

Abstract: 1376083 Head circuit for digital recording U HOFMANN 31 Jan 1972 4420/72 Heading G5R [Also in Division H3] A magnetic head circuit for recording binary digits includes a condenser Cp in parallel with the head coil L, R L  to constitute an oscillation circuit, and two transistors T 1 , T 2  which are switched by the input voltage e(t) and are connected through respective diodes D 1 , D 2  to the head coil-L, R L  such that when one transistor conducts energy is supplied to the oscillation circuit, the other transistor then being non- conducting to prevent continued oscillation. As shown, the transistors T 1 , T 2  may be of opposite conductivity typesand are connected to the same side of the coil L, R L . Input voltage e(t) is applied to the transistor bases through base resistors R B1 , R B2 . When input voltage e(t) changes, one transistor conducts and the oscillation circuit makes one half of an oscillation before coil current i L  stabilizes. The transistor collectors are biased by a voltage U B  less than or equal to the input pulse voltage e(t). In an alternative embodiment, Fig. 1 (not shown), the transistors (T 1 , R 2 ) are of the same conductivity type, being connected to opposite ends of coil (L), which is centre-tapped to bias voltage (-U B ). Transistor (T 1 ) base is connected to input e(t), while transistor (T 2 ) base is connected to the inverse e(t).
