A brocade corresponding to the original design is thus woven directly and at the same time pattern cards for the same design are produced to be used subsequently on jacquards. The entire surface of the pattern is scanned by a spot light and according to the varying shading produces photo-electric currents in a tube 5. The output circuit of this is connected through a relay 6 to an amplifier 7 operating a movable contact 10 connected to the energizing coils of electromagnets operating the device 12. This is connected by cords and hooks to the loom harness 16 and by cords 35 to weights 34 connected by cords 33 to the spring-controlled rods 25. After one revolution of the pattern drum, the device 12 raises the warps corresponding to white parts in one line of the pattern, and a weft is inserted by the shuttle 20 to produce the brocade. Simultaneously the weights 34 corresponding to lifted hooks and warps are raised slackening corresponding rods 33, so that corresponding controlling rods 25 may be moved by their springs over the heads of corresponding punch rods 21. The punching die 29 is now lifted and the card 31 is punched by those rods 21 that are blocked by the rods 25 and in a manner corresponding to the design. The brocade loom or card cutting machine may be maintained inoperative. A modification is described wherein the relay 7 is omitted and the punch controlling rods are connected to transverse rods moved selectively into the path of a reciprocating shifter. The device 12 may be provided with a distributer comprising contacts equal in number to that of the picture elements in one scanning line of the design and connected to a corresponding number of electromagnets.

Abstract: 794,143. Centrifugal compressors. RHEINISCHE MASCHINEN UND APPARATE GES. Feb. 16, 1956 [Feb. 16, 1955], No. 4901/56. Class 110 (1). In a rotary compressor in which the flow through the impeller has a radially outward component, the impeller flow channels are shaped so that the velocity of the fluid relative to the impeller can be increased from a sub-sonic to a supersonic value within the impeller. The meridional component of velocity may be increased within the impeller from a subsonic to a supersonic value. The Mach number may increase linearly or parabolically with respect to the length of the impeller flow channels. Further increase of the Mach number occurs in a bladeless annular discharge passage surrounding the impeller. A rotating system of normal compression shocks may be produced in the impeller, or an annular compression shock may be produced in the bladeless annular passage. The side walls of the bladeless annular passage may be parallel or may converge to provide a smooth transition from the decreasing cross-sectional area of the impeller to the increasing cross-sectional area of the annular passage. Smooth transitions are also provided in respect of the Mach number and the static pressure, the Mach number continuing to rise in the annular passage and the static pressure changing smoothly at or before the impeller outlet from an increase to a decrease. In the compressor shown in Fig. 8, the flow is directed by a bladed inlet 4 into a partly radial direction before entering the impeller 8. The impeller has radial blades 9 bent round at the inlet. The bladeless annular passage 10 is followed by a spiral diffuser 11. The impeller may be preceded or followed by similar or other compressor stages, and may have forwardly or backwwardly curved blades.
