Abstract: 569,664. Automatic smallarms. TRIGGS, W. W. (Western Cartridge Co.). May 22, 1943, No. 8174. [Class 119] . Consists of an ejector-mechanism for automatic firearms having a rotary breech-bolt operated by an action-slide impelled rearwardly by a short-stroke impact, gas-piston, and has for its object to eject the fired cases forwardly and upwardly away from the firer. The extractor 57 is formed on an arm 53 pivotally mounted on the top part of the breech-bolt 23, seen in plan in Fig. 5 shortly after the commencement of its forward, breech-closing movement. At the lower part of the breech-bolt, an outwardly spring-pressed ejector plunger 49, Fig. 8; is mounted. The action-slide 29, 30 has an upward extension 59, the front face 60 of which registers with the front end of the breech-bolt during the longitudinal movements of the latter. The combined action of extractor and ejector during the rearward movement of the breech-bolt is to tilt the empty case 44 into the position shown in Fig. 6 (also in full lines in Fig. 5) ; the action of the breech mechanism is so rapid, however, that the return movement begins before the case 44 has cleared the ejection opening 16a, and the face 60 of the slide hits the base-end of the cartridge case and completes its ejection in the forward direction, as shown at B, Fig. 5.

Title: Production of coated paper
IPC: B05C1/12
Filed: 1964-02-28
Abstract: A method of making coated paper comprises applying to one surface of an uncoated dry paper web, by a first trailing blade coater means, a prime coating composition comprising an aqueous suspension of mineral pigment and adhesive while moving the web forwardly in contact with a resilient-surfaced backing roll, applying a top coating composition comprising an aqueous suspension of mineral pigment and adhesive to the prime coated paper web by a second trailing blade coater means at a position further on from the area of the prime coating application and before the prime coated paper web has been heat-dried and while the web remains in contact with the roll, thus merging the successively applied layers of coating composition, stripping the web from the roll and heat-drying it.  The term trailing blade coater means includes coating devices where a dip roll is used to apply to a paper web a coating composition which is then doctored by means of a flexible blade spaced from the dip roll, puddle coating devices where paper on a backing roll is passed through a trough containing coating composition, the outlet edge of which is defined by a flexible blade and coating devices where the coating composition is applied under pressure through a jaw-like trough extending transversely of the web, the trailing lip comprising a blade which serves as a metering edge and which may be followed by a doctor blade.  The components of the top and prime coating compositions may be the same, or different, provided that the two are compatible with each other.  The mineral pigment of the coating compositions may be clay, TiO2, or CaCO3, and the adhesive component may be corn starch, casein, or various aqueous synthetic polymeric dispersions or latices, e.g. polyvinyl acetate latex, polyacrylic resin latex, or butadiene-styrene copolymer latex.

Title: Improvements in or relating to data storage systems
IPC: G11C11/56
Filed: 1961-03-08
Abstract: 896,749. Tunnel diode bi-stable circuits. INTERNATIONAL BUSINESS MACHINES CORPORATION. March 8, 1961 [March 23, 1960], No. 8408/61. Class 40(6). [Also in Group XIX] The columns of a storage matrix comprise series connected tunnel diodes Dl, D2 . . . each capacitively coupled to row conductors. Current generators CGS1, CGS2 . . . maintain the current through the diodes at the value represented by point A of Fig. 1. When it is required to read in information to a diode current to the selected column is supplied from a generator such as CGB1, and the state of the diodes in this column is represented by point X. Additionally a voltage pulse is applied across the row conductors, H1 and H2, say, adjacent the selected diode from a pulse generator PG1 and through a transformer coupling Tl. This voltage is sufficient to take the diode Dl past the point Cl and it assumes the state represented by point Y. To prevent spurious switching the magnitude of the voltage pulse necessary to switch a diode may be increased by putting resistors either in series with the diodes in the columns or with the capacitors in the row conductor couplings. Non-destructive read-out may be by means of sensing the voltage change in a given column on switching a diode in that column. The sensing means, such as SE1, comprises a delay 11 and differential amplifier 10 in which the voltage on line L1 is compared before and after a read-in operation. Another method utilizes the change in apparent resistance to A.C. of a switched diode. The A.C. is applied to the rows by means of  generators, such as VG1, and the detection of the voltage across the diodes is by means of voltmeters V1, V2 . . .
