Abstract: Abstract of the Disclosure A cartridge case and cartridge arrangement in which a [metal] base is joined along an annular intermating chevron-shaped joint with a [glass-reinforced plastic] sleeve. In the illustrated and preferred embodiment the base is metal and the sleeve is glass-fiber-reinforced plastic.  The case has a propellant, projectile, and a percussive primer.  A plurality of circumferentially spaced vent holes are formed in the plastic sleeve along a portion of the chevron joint as an aid to reducing excessive interface friction loads at the chevron joint during firing of the cartridge.  A less preferred modification is disclosed in which the base is formed of plastic material or a composite glass-plastic or other composite plastic material, and the sleeve is formed of metal.  A further less preferred modification is disclosed in which both the sleeve and the base are formed of similar materials.

Abstract: ABSTRACT OF THE DISCLOSURE     A steel sheet plated with Pb-Sn alloy, suitable for use as the material of automobile fuel tanks for containing fuel having alcoholic content.  The steel sheet has an NiSn alloy layer or a composite layer includ-ing a backing Ni layer and the NiSn alloy layer; the NiSn alloy layer or the composite layer being formed on the steel surface to have a thickness of 0.035 to 1 µ; and a plating layer of a Pb-Sn system alloy formed on the sole NiSn layer or the NiSn layer of the composite layer.      The steel sheet plated with Pb-Sn alloy can be produced by plating the steel sheet with Ni backing, forming a Pb-Sn system alloy layer by a hot dip coating, and rapidly cooling the steel sheet.  Alternatively, the steel sheet plated with Ni is subjected to successive electroplating with Sn and then with Pb, and is then treated at a specific temperature for melting and diffusing Sn into Ni to form the NiSn layer.

Abstract: ABSTRACT           A method is described for the continuous manu-facture of inlaid vinyl sheeting using different colored plastisols and rotary screen printing equipment.  The printing equipment comprises an unwind stand, an accumulator, a plurality of printing stations, a coating station, an oven, a second accumulator, and a wind up stand.  Optionally an embossing station may also be used.  Each printing station comprises (i) a rotary screen through which a different colored plastisol is squeezed to form a colored pattern on a base layer and (ii) a hot air dryer for partially drying the plastisol deposited on the base layer.  In accordance with the invention, the viscosity of the plastisol and the rate of drying is such that plugs of plastisol are deposited on the base layer by each screen to form discrete portions of the total pattern created.          Several different rotary screens are used to deposit these plugs of colored plastisols on the base layer so as to build up a pattern from the different colored plastisols.          Advantageously, a wear coat is deposited on top of the layer of differently colored plastisols so that the final product consists of three layers:  a hacking, a decorative layer of differently colored plugs of plastisol, and a wear coat.

Abstract: PROGRESSIVE TRANSMISSION OF TWO-TONE  FACSIMILE            Abstract of the Disclosure A method and apparatus is disclosed for the transmission of two tone pictures progressively in several stages.  Progressive transmission enables a viewer to receive and utilize pictures in a small fraction of the normal transmission time.  In a first stage, information representing groups of picture elements of preselected lines of the scanned picture is transmitted which allows a coarse version of the picture to be reproduced at a receiver.  During the subsequent stages the horizontal resolution of the previously transmitted scan lines is improved and additional scan lines are transmitted in a specific order until the received picture is an identical copy of the original picture.  The progressive picture information is efficiently transmitted in one of several line-by-line codes resulting in a total transmission time not significantly longer than the time for a nonprogressive transmission.

Abstract: Abstract of the Disclosure A  tag attacher in which pulling a trigger causes a cam plate to be lifted against spring force and a linked cutting edge to be stuck into a connecting bar of a tag pin assembly at the same time that one of tag pins of the tag pin assembly loaded in the tag attacher is driven through a hollow needle; and in which when the trigger is released the spring force lowers the cam plate causing the cutting edge stuck into the connecting bar of the tag pin assembly to pull down the connecting bar so as to guide the crossbar of a next located tag pin to the inlet of the hollow needle.  With this tag attacher, it is possible is successively drive tag pins into merchandise if the tag pin assemblies used have different inter-pin pitches.  Further more, since the connecting bar that has been removed of tag pins and fed out of the tag attacher has notches, it can easily be torn off by hand.
