Abstract: 1471997 Measuring elasticity J BORST & FILS SA 20 Aug 1974 [19 Sept 1973] 36529/74 Headings GIN and G1S [Also in Division G4] A strip 1, Fig. 1, is stretched between a first roll 2 of radius R 1  and a second roll 4 of larger radius R 2 , driven at a common angular velocity by a motor 6, whereby the tension Ti measured at 14 upstream of roll 2 is smaller than the tension T 2  measured at 16 upstream of roll 4, and the elastic coefficient K is given by K = T 2 -T 1 /R 2 -R 1  R 1 . When the strip is moving, the tension T 1  signals must be delayed by a factor (1 - e<SP>-vt/l</SP>). where v is the linear velocity of the strip and l the length of strip between the rolls 2, 4, before it is compared with T2, thereby modifying the above Formula to:- K = T 2 -T 1 (1-e<SP>-vt/l</SP>)/R 2 -R 1 , R 1 . The delay factor is determined in the network 17.

Title: Delivery mechanism for nut tappers
IPC: B23Q7/00
Filed: 1932-12-30
Abstract: 392,122. Tapping nuts. CLOUSE, W. L., Tiffin, Ohio, U.S.A. Dec. 30, 1932, No. 36955. [Class 83 (iii).] A nut-tapping mechanism of the type in which the nuts are rotated over a reciprocating tap provided with an arcuate stem has a rotatable shifter device adapted to act on the tapped nuts carried by the stem. The bed 1 of the machine has guideways 3 for a slide 2 reciprocated by cam-and-lever mechanism 11, 12 from a shaft 10 connected to the drive for the nut holder 7. A fixed strip 4 intersects the slide 2, its upper surface being flush with that of the slide and serving to support the nuts which pass off the tap 18, the arcuate stem 20 of the tap is concentric with a block 27, fixed to the slide, through the centre of which passes a rotatable pin 21, the upper end of this pin carries a shifter device 22 and the lower end is connected by a lever to the fixed member 4 so that it is rotated upon movement of the slide 2. The nuts are fed from a shoot 8, and pushed into position in the rotating holder 7 by a plunger 9 so as to engage the tap 18, the latter is fed into the nut bv movement of the slide 2 and the friction of the tapped nuts resting on the member 4 tends to move these towards the arcuate portion 20 ; the shifter device having a lip 23, Fig. 2 (not shown), is moved and tends to push the nuts, one at a time, from the end of the tap stem into a receptacle 29, the return movement of the slide 2 frees the lip 23 from the nuts and the shifter swings back to its initial position. An alternative method of oscillating the shifter device is described comprising crank-and-lever mechanism driven by gearing from the nut-holder. In lieu of the oscillating shifter device a rotatable ratchetoperated disc with a shaped rim may be used for moving the nuts around the arcuate portion of the stem.

Title: Improvements in or relating to radio signalling systems
IPC: H03C7/02
Filed: 1934-12-24
Abstract: 433,842. Wireless signalling. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., Electra House, Victoria Embankment, London. (Assignees of Wolff, 1.; 41, West Walnut Avenue, Merchantville, and Linder, E. G.; 306, Cooper Street, Camden, both in New Jersey, U.S.A.) Dec. 24, 1934, No. 36980. Convention date, Dec. 23, 1933. [Classes 39 (i) and 40 (v)] Signals are transmitted, preferably on microwaves, by using a body of ionized gas situated in a magnetic field to vary the plane of polarization of the emitted wave. As shown in Fig. 2 the wave is emitted by a dipole aerial 3 at the focus of a reflector 7. The wave passes through a tube 9 containing ionized gas, such as neon, and the signal varies the gas ionization and so rotates the plane of polarization of the wave. The tube 9 is surrounded by a coil 47 connected to a D.C. source 49, and by a second coil 51 which is traversed by a high-frequency current from the source 53 modulated by the signal from the microphone 25. The signal may be received by using a dipole receiving aerial set at a suitable angle so as to give a response which varies with the varying plane of polarization of the arriving wave. As shown in Fig. 2, however, the wave passes through an analysing grating 58, which converts the wave into an amplitude-modulated wave. The receiver may then be equally responsive for all planes of polarization, and may comprise a neon tube 61 at the focus of a reflector 33, and with its electrodes connected to a receiver 35<1>. Alternatively two receiving dipoles at right angles to each other may be arranged for independent reception, and may feed the same receiving telephone. In another form of modulating tube, an axial cathode and a cylindrical anode are connected by a D.C. source. The microphone is connected through a transformer to a coil surrounding the tube. In a further form shown in Fig. 3, a series of long helical tubes 73 of different diameter are arranged one within another. The tube electrodes 75 are connected in parallel to a D.C. source 15 ; and a coil 17 surrounding the outer helix is energized by the microphone 25 through a transformer 23.
