Title: Improvements in or relating to methods and apparatus for adjusting the resonant frequency of the moving element of an electrodynamic device
IPC: G11B7/00
Filed: 1931-11-04
Abstract: 391,509. Frequency and inductance measurements. ELECTRICAL RESEARCH PRODUCTS, Inc., 195, Broadway, New York, U.S.A.-(Assignees of Gibson, R. D. ; 144, Elm Avenue, Rahway. New Jersey, and Harley, J. B. ; 875, West 181st Street, New York, both in U.S.A.) Nov. 4, 1931, No. 30623. Convention date, Dec. 20, 1930. [Class 37.] The frequency of mechanical resonance of an electrodynamic device is measured by determining the impressed frequency at which the motional electrical impedance is a maximum. Apparatus is shown for ascertaining the resonance frequency of the filaments of light valves for sound recording in order to facilitate the adjustment of their tension so that resonance shall not occur within the audiofrequency range. The light-valve ribbons are connected across the output circuit of vacuum tube oscillator 0 through clips 4 and two-way switch 3. The output circuit'of the oscillator 0 is also connected through a resistance Rand transformer 5 to the input of an amplifier having in its output circuit an ammeter 13 shunted by a resistance 14, in order to damp its oscillations. With the switch 3 in its right-hand position a resistance 15 of known value is connected in place of the light-valve ribbons across the oscillator 0. By employing a variable resistance 15, the meter 13 is calibrated in terms of the resistance. The switch is changed over to the left-hand position, thereby substituting the light-wave ribbons for the resistance 15. The oscillator output voltage of increasing frequency is then impressed, in successive steps, on the valve ribbons and the impedance is measured on the instrument 13. The frequency of the oscillator 0 at which this reading is a maximum is the resonance frequency at, the particular tension to which the ribbons are stressed. This tension is then increased until the resonance frequency has the desired value. Specification 314,575, [Class 37, Electricity, Measuring &c.], is referred to.

Title: Improvements in the manufacture of soldered tubing
IPC: B21C37/09
Filed: 1923-12-06
Abstract: 229,424. Bundy, H. W. Dec. 6, 1923. Tubes. - Overlapped or multiple-ply brass or other tubes for automobile radiators, gasoline lines &c. are made by passing a metal strip through a forming apparatus and then through an apparatus for soldering the seam arranged in line therewith. A solder coated or plain strip fed from a spool a, through a fluxing bath b, then through rolls c for removing excess flux and is then converted by a series of dies e and pairs of rolls f into a multiple-ply or an overlapped tube. The tube is then passed through one or more twopart chambers such as g, h, heated by burners i so as to melt the solder coating and solder the plies together. The chamber h is slotted at k for the passage of a solder strip m which is fed by rolls n and belt o at a speed depending on the speed of the tube, and is melted in the chamber. The solder between the plies, by capillary action draws in some of the additional solder so as to effect a more even distribution of the solder. The chambers are provided with perforations p, q, to receive carbonized flux, which is scraped off the tube during its passage therethrough, and is punched or blown out a intervals. The tube then passes through a graduated series of dies r for removing surplus solder and for reducing the tube to size. These dies are heated by flames burning at the ends of passages z supplied with combustible gas from a tube x and with air through passages y. The tube then passes through a water jacket 1 supplied by a pump with water from a reservoir 3 so as to set the solder. The strip may be coated with a mixture of 70 parts of tin to 30 parts of lead. Specificaton 229,412 is referred to.

Filed: 1956-10-09
Abstract: 843,811. Mixing appliances. NAUTA, J. E. Oct. 9, 1956 [Dec. 20, 1955], No. 30762/56. Class 86 A device for mixing powdered, granular or plastic materials for example, cereals, meal or chemical products, comprises conical vessels 1, 2, with respective helical blade stirring members 36, 37, which rotate about their own axes 32, 33 and revolve close to the walls of the vessels about the central axis 5, 6 thereof forcing material mixed by each stirrer to be raised and passed in turn through an aperture common to both vessels as each stirrer completes one revolution around the walls. The rotary motion of the stirrers 36, 37 about axes 32, 33 is effected by driving means from a pulley 28 to a shaft 27 through bevel gears 26, 25 and 24, 23 and spherical articulated couplings 31, 30. The platentary rotation of the stirrers about axes 5, 6 is effected by two rotary arms 14, 15 respectively mounted on axles 12, 13 which are driven through worm gearing by a horizontal shaft 16 having a pulley 19 engaged by a belt 20 which connects to a pulley 29 on the shaft 27, this latter being driven by, for example, an electric motor. The arms 14, 15 are synchronized to rotate in phase by similar gears on the axles 12, 13 thus enabling the paths of stirring members to overlap above the common aperture formed by the intersection of the two conical vessels. A tube 56 (Fig. 5) with a rotary shaft 58 and screw blades 57 can be fitted to connect the lower sides of the vessels to increase the recirculation of the materials between the two vessels. Material to be mixed is fed into a charging hole in a top plate 8 common to both vessels and after mixing it is discharged through respective sliding valves 34, 35. Various modifications are described which use 3 or 4 intersecting conical vessels and in which screw conveyors are arranged at the lower ends of the vessels to increase the passage of materials from one vessel to another.

Abstract: 1475374 Laser rangefinders SIMRAD AS 11 July 1974 [13 July 1973] 30771/74 Heading H4D Apparatus for testing a laser rangefinder, comprising a laser transmitter and light sensitive receiver, consists of means for testing optical alignment and an optical detector, adjustable delay means, and light pulse transmitter whereby a return pulse of known duration is generated to measure the accuracy of the time measurement means employed in the rangefinder. A light pulse from the laser is focused along light path a (Fig. 1) by lens 11 via beam splitter 13 on to plane 12 which may be a film, paper, &c., on which is produced a burn mark. Some of the laser light passes through beam splitter 13 along path aa to fall on light sensitive transistor detector 14. Electronic unit 18 operates as a delay unit to simulate a particular range and may utilize monostables which may be automatically or manually switchable to provide variable delays (see Figs. 2a-2d, not shown). Pulse transmitter 17, consisting of an L.E.D. or a semi-conductor laser transmits a pulse, when triggered by unit 18, which follows path bb through beam splitter 16 to the rangefinder receiver (not shown) along path b. The range-finder telescope is focused by lens 15 along path b via beam splitter on to plane 12 so that the laser and telescope alignment may be checked. In a practible embodiment, Fig. 3, separate windows 25 and 32 are provided for the TX and RX beams from the rangefinder. Attenuating filters 27 and 36 reduce the laser light intensity and prevent a TX pulse being directly reflected by beam splitter 16 back into the rangefinder receiver. Detector 14 receives light reflected from specular reflector 31, light from pulse TX, 17 passes through lens 17 and pin hole 34 in screen 33, which is used to initially align the unit before tests begin. Light on to film plane 12 is focused by lens 28. In another embodiment using a coaxial laser rangefinder (not shown), the transmitted and return pulses travel along a coincident light path. In other embodiments (Figs. 4 and 6, not shown) a single lens may be used for both light paths a and b when these are close together.
