Title: Apparatus and method for creasing and bending synthetic plastic sheet stock
IPC: B31B50/36
Filed: 1963-10-09
Abstract: 976,281. Creasing &c. plastic sheets. C. E. PALMER. Oct. 9, 1963 [Oct. 11, 1962], No. 39765/63. Heading B6J. Apparatus for creasing and bending plastic sheet stock comprises a pair of rotary discs, one having a blade edge on its periphery and the other a periphery of resilient rubber-like material. The discs are both driven in opposite directions so that their peripheries travel at the same speed, and the plastic sheets are creased and folded by being pressed by the blade edge of one disc into the resilient surface of the other disc. Fig. 4 shows apparatus for forming a rectangular tubular member from a flat plastic strip 34, there being four discs 38a, 38b, 38c, 38d with resilient peripheries, and four co-operating blade-edge discs 40a, 40b, 40c, 40d. The shafts of all the discs are power driven from drive shafts and gearing as shown, the blade discs being mounted in an elongated mandrel 42 so that their edges protrude. The plastic strip 34, as it approaches the mandrel 42, is supported by guiding rollers, and is first engaged by the discs 38a, 38b and 40a, 40b, and later by the discs 38c, 38d and 40c, 40d, further guide rollers and deflecting rollers being arranged immediately before these latter discs to shape and support the strip. The strip is now formed into rectangular tubular shape with the free ends overlapping. Triangular and other shapes may be formed by suitable mandrels, guide &c. rollers, and discs. The blade-edge disc may have an integral V-shaped edge, or an undercut edge which is shaped on one face to assist the folding of the creased plastic strip, or the edge may be a separate member secured to the disc and of frusto-conical form, and secured at an acute angle to the plane of the disc in a circumferential recess in the disc. The co-operating disc has a resilient, rubber-like material such as sponge rubber, or a synthetic organic polymer such as polyurethane, secured to its periphery, and has a rectangular , V, or other shape to suit the particular creasing &c. operation and the shape of the co-operating blade edge. The strip 34 may be biaxially oriented polystrene of five to thirteen mils. thickness, and is overfolded about twenty to forty degrees to achieve the desired shape when it leaves the discs. The creased and folded strips are further processed to produce tubular or tray-shaped containers. Specifications 906,075, 937,733, and U.S.A. Specification 2,954,725 are referred to.

Abstract: 1357807 Tuning indication; transistor receiving circuits RCA CORPORATION 25 Aug 1971 [26 Aug 1970] 39832/71 Headings H3Q and H3T A tuning and signal strength indicator for an FM radio receiver having a plurality of amplifier-limiter stages, comprises a plurality of amplitude detectors, the input of each of which is respectively connected to the output of one of the amplifier limiter stages, a combining network which adds the outputs of the amplitude detectors and applies the combined output to an indicating device. Capacitors 242, 252, 258, Fig. 2, respectively couple the first, second and third amplifier limiter stages (Fig. 1, not shown) to detector transistors 214, 218, 222, while capacitor 263 couples the discriminator cricuit to detector transistor 226. Detector transistor 226 is provided with an emittercircuit integrating capacitor 594, but the rest of the detectors depend upon incidental circuit capacitance for integration. Each detector is D.C. coupled to a common-emitter amplifier 216, 220, 224, 228 respectively, the collectors of these transistors being commoned to drive a D.C. amplifier comprising diodes 234, which may be a transistor with base and collector strapped, and transistors 230, 232, the emitter current of transistor 232 being fed to the indicating device 572. An A.G.C. potential for the R.F. stage of the receiver is derived from the collector of transistor 216 via emitter-follower 285 and potentiometer 501. The threshold potential for the detector transistors 214, 218, 222 is provided from the 5À5v. supply line by means of a pair of transistors 238, 240. Supply circuit.-Point 608, Fig. 3, is connected to the I.F. amplifier limiter at a point that provides a reference voltage of approximately 1À0 v. to earth, which biases transistor 618. Transistor 618 provides a bias for transistors 624, 626, 628, a potential of 1-3 v. being derived on line 215 from the collector of transistor 628. Transistor 624 provides from its emitter current for series-connected diodes 630, 632 and Zener diode 634. A stabilized potential of 5À5 v., equal to the Zener diode drop is derived from the emitter of transistor 640 and also from each of the emitters of double-emitter transistor 612.

Abstract: 1,085,390. Axial-flow fans. TURBOWERKE MEIBEN VEB. Sept. 18, 1965, No. 39882/65. Heading F1C. A rotor (or stator) for an axial-flow fan comprises blades 4 followed by flaps 7, each blade 4 and its associated flap 7 being spaced apart to form, in effect, a slotted blade. Each blade or flap is angularly adjustable about its axis when nut 6, 9 is slackened. Alternatively the blades and flaps are jointly rotatable by a common adjusting mechanism. Three bolts 10 each have a threaded end 15 engaging a threaded bush 16 carried by a rotor disc 2, the other end 13 being secured by a nut 12 in an arcuate slot in a rotor disc 3. When the nuts 12 are slackened, the arcuate slots allow the rotor disc 3 to be turned relative to the rotor disc 2 to displace the flaps 7 circumferentially relative to the blades 4. After a locking device on a central pinion 18 has been released, the pinion can be rotated by engagement of a tool with slots 19, thereby turning the threaded bushes 16 through gear-wheels 17, so that the rotor disc 3 is axially displaced relative to the rotor disc 2, whereby the blades 4 and flaps 7 may, when viewed in the circumferential direction, overlap slightly as shown or have a small gap between them.
