Filed: 1966-08-26
Abstract: 1,160,302. Coating apparatus; spray producers. A. PODESTA and C. VIGNATI [trading as VETRI INDUSTRIALI] 26 Aug., 1966 [27 Aug., 1965], No. 38456/66. Headings B2F and B2L. Apparatus for the distribution of a sealing compound on the internal face of a cap comprises a cap support 360 for holding the cap 2 stationary and a closable centrifugal distributor comprising a conical plate 332 which is rotatably driven around an axis 1 and slidable parallel with this axis, and a back plate 320 freely mounted and rotatable in the same way by the action of the conical plate in the closed position of the distibutor. In the preferred embodiment shown the apparatus consists of a fixed part 31, a part 32 which is freely mounted and rotatable on bearings 321 and a part 33 which is rotated by means of a motor (not shown) and can slide axially and which carries the conical plate 332 forming part of the distributor. The part 33 is urged upwards by a spring 338 to a position which closes the gap between faces 333 and 322 of the members 332 and 320 and the part 33 can be moved downwards against the action of spring 338 so as to open the distributor gap by means of an arm 335 acting on plate 334. In operation pipe 312 is connected to a reservoir containing the sealing compound under slight pressure so that the spaces 341, 342 in the apparatus are filled with the sealing compound. The cap 2 is placed on plate 360 and is held thereon co-axially with axis 1 'by magnetic or vacuum means. The shaft 330 of part 33 is then rotated and the distributor and the cap brought into a position such that the surfaces 322 and 333 are exactly opposite the zone where it is desired to place the sealing compound (right-hand side of the figure). The arm 335 is then actuated to press on plate 334 and thus move the shaft 330 and conical plate 332 downwards to separate the surfaces 322 and 333 and open the distributor. The sealing compound is thus projected on to the inner rim of the cap 2 by centrifugal force and the quantity deposited for a given period of opening of distributor depends on the speed of rotation and the amplitude of the sliding movement of the shaft 330. After the compound has been deposited the distributor is closed by reverse action of arm 335, the cap and the distributor are spaced from one another and the cap moved away to be baked.

Title: Improvements in or relating to horizon indicating systems
IPC: G01C9/18
Filed: 1956-12-20
Abstract: 844,522. Photo-electric level indicators. MOTOROLA Inc. Dec. 20, 1956 [Dec. 21, 1955], No. 38894/56. Class 40(3). In a device for indicating deviation from the horizontal, an opaque liquid 22 which includes a bubble 23 is housed between the concave face of a concave-convex lens 20 and the convex face 15 of a cathode ray tube 10, and an electron beam scans the screen 16 to produce a luminescent spot which is detected by a photo-cell 35 as it passes across the bubble 23. To determine the X- and Y- direction displacements of the bubble sweep generators 30x, 30y, whose signals are applied to plates 12x, 13x and 12y, 13y in planes mutually at right angles, develop series of long and short duration sawtooth scanning signals respectively. The luminous spot moves unidirectionally in turn along a series of parallel Y scanning lines. The signals from the photocell are fed through an amplifier and pulse shaping circuit 36 (see Fig. 2a, not shown) to X and Y co-ordinate detector circuits 31x, 31y (see Fig. 2b, not shown) to which are also applied the sawtooth scanning signals. The amplitudes of the sawtooth scanning signals at the time of a signal from the photo-cell are proportional to the X and Y co-ordinates of the displacement of the device from a horizontal position and these amplitudes are passed to X and Y integrator circuits 40x, 40y to give continuous signals. In a modification, two cathode ray tubes are employed having different thicknesses of opaque liquid so as to compensate for errors due to viscosity of the liquid.

Title: Pulse train detection
IPC: G06F7/02
Filed: 1966-09-02
Abstract: 1,146,278. Radio-navigation. INTERNATIONAL STANDARD ELECTRIC CORP 2 Sept., 1966 [8 Sept., 1965], No. 39313/66. Heading H4D. The Specification describes a circuit for detecting the identity code signal from a TACAN type beacon. Such a signal is made up of pulse pairs having a recurrence frequency of 1350 c/s., i.e. a period of 740 Ás. Each pulse pair is converted to a single pulse and the resulting train is applied at 11 to bi-stable circuit 10. An oscillator 14 produces two clock signals in antiphase at a frequency of 68.175 kc./s. Each signal produces a respective clock pulse train by means of a monostable circuit and an invertor. Bi-stable circuit 10 is set in a +3V state by the pulse at 11 and is returned to a 0V state by the next clock pulse on line 34. The resulting 1350 c/s. pulse output of circuit 10 is fed to a transistor 13 which adjusts the two levels of the signal to - 3V and - 20V. The adjusted pulse signal is fed to a hundred stage shift register 50 having the clock pulse trains, after level adjustments in transistors 19 and 20, applied thereto as shift pulses. A pulse in the register reaches the 50th stage 732.6 Ás, i.e. 740 Ás-1%, after its application to the input thereof. The output of the 50th stage is applied, via a level adjusting field effect transistor 22, to a 15 Ás monostable circuit 21. Thus there will be a pulse present at the input of the shift register simultaneously with an output from circuit 21 in the case of two consecutive pulses having a spacing of 740 Ás 1 %. A third consecutive pulse is similarly investigated by feeding the output of the 100th stage of the shift register to a 30 Ás monostable circuit 23. The outputs of circuits 21 and 23 are inverted and fed to a NAND gate, together with the output of circuit 10, such that NAND gate 25 is only activated when three consecutive pulses occur having spacings of 740 Ás1%. Activation of gate 25 triggers monostable circuit 27 to produce a pulse which is integrated at 28. When sufficient pulses have been received having the required spacing, the output of integrator 28 rises sufficiently to trigger level detector 30 and apply a gating signal to gate 31, whereby a 1350 c/s. tone signal at 32 may be gated for a utilization.
