Title: Improvements relating to the manufacture of varnishes, lacquers or the like
IPC: C09D101/08
Filed: 1927-02-08
Abstract: 290,707. Fraser, L. M., and Smith, W. S. Feb. 8, 1927. Rotary mixers.-In the manufacture of paints, varnishes, &c. the constituents are entirely enclosed in a container while mixing, dispersing, or dissolving them and them forced, as by purified compressed air, through a filter to another container. The air may be allowed to escape after it has served its purpose. Pressure may also be used to transfer the products from any component part of the plant to the next and to the trade receptacles, to prevent contamination by dust &c. Vapours arising during treatment may be condensed and returned to the system, or prevented from escaping by liquid seals. A suitable form of plant comprises an enclosed rotatably mounted mixing-drum 1, optionally fitted with internal agitating means, a conduit 9, detachably connected by a plug 8 and leading to a filter 10, which delivers to a receptacle 12. Air pressure is applied by a pump 16, which stores compressed air in a reservoir 14, whence it is led, preferably after drying and filtering, by a detachable conduit 5 to the mixing drum. The inlet for compressed air and outlet for the contents may be axially and non-detachably arranged.

Title: Improvements in or relating to continuous drier apparatus
IPC: F26B15/12
Filed: 1965-01-27
Abstract: 1,048,163. Endless conveyers. DE FRANCISCI MACHINE CORPORATION. Jan. 27, 1965 [Jan. 31, 1964], No. 3560/65. Heading B8A. [Also in Divisions A2 and F4] In apparatus for drying spaghetti extruded from a conventional press 10, Fig. 1, the spaghetti passes on rack rods 20 carried by conveyers through a drying apparatus comprising a preliminary drier 11 through which the spaghetti is conveyed on the rods in single tier flow and from which it is conveyed by an input elevator and transfer means 12 into a finishing drier 13 wherein it passes in a multi-tiered single pass on to an accumulator 14 for temporary storage of the dried spaghetti and from thence by a discharge elevator and transfer means 15 to a stripper 16. The empty rods are returned on an automatic mechanism 17 to the press 10. The transfer means 12, Fig. 3, comprises a pair of vertically mounted endless conveyers 22 intermittently driven through a sprocket 23 by a motor 31 and having thereon spaced rack rod support lugs 27A ... 27D, 28A ... 28D. Power is supplied and the conveyers 22 move when switches 37 in the power circuit to the motor having triggers 38 adjacent the chains 22 and chains 21 in the preliminary drier 11 are actuated by the lead rod on the chain 21, and continues until the next lug on the conveyers 22 engages a trigger 40 of a switch 41 in the motor circuit. The motor restarts when the next rack rod 20 reaches the correct transfer position adjacent the chains 22. This action continues until all the lugs are loaded and the lugs 27A ... 27D are positioned adjacent lift-off arms 42A ... 42D, pivotally mounted on a linkage arm 45. The arms 42A ... 42D are normally raised free of the descending rods 20 on a chain 21 but a cam 50 on a sprocket 51 is driven via sprockets and chains 52-54 travels to the shown positions when all the lugs are loaded so that a cam follower 48 reaches the recessed position of the cam and allows arm 45 to drop and the arms 42A ... 42D to intercept the rods 20 which roll on to the conveyer chains 55A ... 55D in the finishing drier 13. A discharge elevator 15 of substantially similar form is described with reference to Fig. 6 (not shown).

Title: Devices for use in measuring the speed of vehicles
IPC: G01P13/04
Filed: 1973-01-25
Abstract: 1410553 Measuring vehicle speed NIPKI PO RADIOELEKTRONIKA 25 Jan 1973 3950/73 Heading G1A The speed of a vehicle moving along a predetermined path is measured by apparatus including two photo-detectors 3a, 3b which receive respective parts of an optical beam directed across the path and divided up into said parts by optical inlet means, the time period between the instants at which the outputs of the two detectors reach predetermined levels being used to calculate the vehicle speed. In Fig.1, the optical means 2 is a square aperture divided in half so that the detectors view respective halves. Each detector is connected to a respective comparator 4a, 4b, which emits a pulse when its respective detector signal falls below the level V 4a  (=V 4b ) of Fig.2, as the vehicle moves through the light beam and progressively obscures the parts of the beam. The pulses from 4a, 4b are applied to trigger circuits 6a, 6b. The first pulse to arrive sets the triggers and the second resets them, the pulse produced from the triggers 6a or 6b being of a duration dependent on the speed of the vehicle, which is calculated by device 8a or 8b, it being known that the vehicle has travelled halfway across the input aperture 2. In order to determine the direction of vehicle travel, monostable multi-vibrators 5a, 5b are provided, together with coincidence circuits 7a, 7b. The monostables are triggered by the comparators and their pulses have a duration greater than the output pulse from triggers 6a, 6b for the lowest expected speed. Since the output pulses from the monostables will be shifted in time, only one coincidence circuit will produce an output for one particular direction of movement. For this reason the two calculators 8a, 8b are provided.

In a hearing aid device at least one alternating voltage having a constant frequency in the range 350 to 1000 c/s. is amplitude modulated by signals within two frequency bands, one band extending from 1500 to 3500 c/s. and the other band having its lower limit within the range 4500 to 6000 c/s. and its upper limit within the range 7000 to 8000 c/s. One embodiment (Fig. 2) comprises a microphone 1, a preamplifier 2 and two filters 3 1  and 3 2 . Filter 3 1  passes only frequencies of 1500 to 3500 c/s. and filter 32 passes only frequencies of 4500 (or 6000) to 7000 (or 8000) c/s. Device 4 amplifies and ascertains the amplitude of the filtered signals. A source 5 produces a sinusoidal voltage of constant frequency within the range 350 to 1000 c/s. An amplifier 6 is provided for amplitude modulating the sinusoidal voltage in accordance with the curve forming the envelope of the output of filters 3 1  and 3 2 . The modulated voltage, after amplification in an amplifier 7, is applied to an earphone 8. Preferably a low-pass filter 9 having a cut-off frequency of 1000 c/s. is connected to a mixer 10 1  to which the output of amplifier 6 is also connected. In a second embodiment (Fig. 3, not shown) separate devices 4 1  and 4 2  deal with the signals from filters 3 1  and 3 2  respectively. Two amplifiers 6 1  and 6 2  are provided, energized by two distinct sources 5 1  and 5 2  each producing a sinusoidal voltage of constant frequency within the range 350 to 1000 c/s., the frequencies being different from each other. Amplitude modulated signals at the outputs of amplifiers 6 1  and 6 2  are mixed in a mixer 11 before being applied to the mixer 10. Miniaturized circuits including semi-conductors may be used.
