Title: Improvements in or relating to jacking apparatus for motor vehicles
IPC: B60S9/04
Filed: 1931-02-20
Abstract: 373,616. Jacking apparatus on motor vehicles. MOTOR JACK CORPORATION, 120, Broadway, and GUTMANN, J., 112, 205th Street, St. Albans, both in New York, U.S.A. Feb. 20, 1931, No. 5464. [Classes 79 (ii) and 79 (iii).] Screw lifting jacks 19, 19<1> at opposite ends of a motor vehicle are selectively driven through universally jointed shafts 32, 32<1> from the main gear transmission box 25 wherein toothed gears 20, 23 respectively feathered on the end portions 18, 22 of the jointed shafts, are slidable into mesh with either of two oppositely rotating gear trains which are continuously driven through an idler 10 from the main driving transmission shaft 26 normally connected by a clutch to the engine crank shaft The idler 10 drives, through a gear 12, a shaft 13 carrying a broad central pinion 14. A gear 15 meshing with the gear 12 causes a second shaft 16, carrying an end gear 17, to be simultaneously rotated in the opposite direction. Thus the shafts 32, 321 are rotatable at will in either direction by sliding the gear 20 into mesh with either of the gears 14, 15 and the gear 23 into mesh with either of the gears 14, 17, the rotation being transmitted to the jacks through worms 43 driving worm wheels 44 rotatably mounted in the jack casings 42. Slidable through but rotatably keyed to the worm wheel 44 is an externally screwed cylinder 45 in threaded engagement with the upper opening 46 in the casing 42 and thus moved up and down. The upper end of the cylinder is enclosed by a cap 48 screwed to the casing 42 and formed with an inner cylindrical wall 49 wherein slides a screwed rod 53, rotation of which is prevented by a feather 52. The lower end of the rod is threaded through the closed lower end 50 of the threaded cylinder 45 and carries a foot or baseplate 54, an aggregate motion thus being obtained of the two screwed members 45, 53. The control means for the shiftable gears 20, 23 comprises a pair of slidable rods 37 extending through the walls of the casing 25 with forked arms 38 respectively engaging collars 39 on the gears and oppositely facing lugs or arms 40 with recessed ends between which is located an operating lever 41, either rod thus being slid in either direction at will by appropriate movement of the operating lever. To provide an automatic knock-out movement for the gears when the jacks are fully extended or retracted, each slidable rod 37 protruding through the casing 25 is connected through a rod 55 to an arm 56 on a rock shaft 57 mounted on the associated jack casing, the shaft being rocked in one direction by contact of a collar 59, at the upper end of the screwed cylinder 45, with an arm 58 and, in the opposite direction, by engagement of a rod 60, carried by the foot 54 of the jack, with a second arm 61 on the shaft.

Title: Improved method of refining lead
IPC: C25C1/18
Filed: 1940-03-28
Abstract: 536,711. Electrolytically refining lead. GUETERBOCK, P. G. J., BAXTER, A. E., and CAPPER, PASS & SON, Ltd. March 28, 1940, No..5627. [Class 41] In refining lead, the base bullion is first fire-refined to remove substantial quantities of copper, tin, antimony, and arsenic and then electrolytically, using as electrolyte, an aqueous alkaline solution of a divalent lead compound, e.g. lead monoxide, carbonate, or sulphate, and glycerine or like polyhydric alcohol not substantially affected by the electrolysis to increase the solubility of the lead oxide. Saponin and/or alizarin may also be added to ensure a dense, coherent lead deposit on the cathode. The electrolyte, which may be heated to e.g. 52‹C., is re-causticized to keep the carbon dioxide content at about 10 lb. per 100 gallons by leading off part from the main circulation, heating to 80‹C. and stirring with hydrated lime, tin, antimony and arsenic compounds being also precipitated thereby. The fire-refined lead is used for anodes which are brushed or scraped e.g. every 24 or 48 hours to remove slime which may be treated for the recovery of bismuth, gold and silver. In an example 100 gallons of electrolyte contained 100 lb. each of caustic soda, and glycerine, 30 lb. of lead as litharge and ¢ lb. of saponin, lagged steel cells being used the current density being 6 amps. per sq. ft. of anode surface, and the voltage 0.2-0.25 per cell.

Title: Improvements in or relating to wide frequency-range magnetic recording and reproducing system
IPC: G11B5/02
Filed: 1948-02-27
Abstract: 654,685. Magnetic sound recording and reproducing. DEPARTMENT OF COMMERCE, DIRECTOR OF THE OFFICE OF TECHNICAL SERVICES OF. Feb. 27, 1948, No. 5940. Convention date, Jan. 17, 1945. [Class 40 (ii)] [Also in Group XXXIX] In a magnetic tape recorder, the highfrequency components of a signal are directly recorded and the low-frequency components are recorded as a modulation of a carrier frequency. The high- and low-frequency signal components may be recorded on opposite edges of a magnetic tape of suitable width or on spaced magnetic tapes consisting of two strips of powdered magnetic material cemented to a non-magnetic plastic ribbon. Recording system. As shown in Fig. 1, high and low pass filters 16, 22 separate the signal components into two channels. The high frequencies are applied to a recording head 18 after amplification at 17 and the low frequencies are applied to a diagonally spaced recording head 27 as a modulation of a carrier frequency from an oscillator 25 after amplification at 26. The carrier frequency used depends on the magnetic recording material and is the frequency which gives maximum output with constant current input. Supersonic biassing may be used, together with condensers 50, 51 and chokes 48, 49 for preventing interaction with the amplifiers 17, 26. Separate supersonic oscillators 46, 47 may be provided for each channel or a single oscillator may be used together with suitable decoupling circuits to prevent interaction between channels. Alternatively, direct current biassing may be provided (Fig. 3, not shown). Reproducing system. Reproducing heads 30, 40 for the high- and low-frequency channels are equally spaced from the corresponding recording heads in the longitudinal direction of the tape, the head 40 being provided with a micrometer adjusting screw 45. The highfrequency signal components reproduced by the head 30 are amplified at 32 and applied to an equalizer 34 in which the attenuation and phase distortion due to recording is corrected. The carrier modulated by the low-frequency components is reproduced by the head 40 and amplified at 42, the low- and high-frequency signal channels being combined in a mixer 36 after the carrier is demodulated at 43. In a modification, the recording heads may also be used for reproduction, suitable switching arrangements being provided for interchanging the recording and reproducing circuits. Construction of magnetic tape. The spaced tapes may be formed of powdered "Alnico" which is mixed with a resinous laquer cement and poured from a container provided with two openings on to a plastic ribbon of cellulose acetate. During the coating process a longitudinal polarizing magnetic field is applied to the tape.

Filed: 1946-02-26
Abstract: 617,085. Switching control of heating resistances. WOOD, B. I. Feb. 26, 1946, No. 5942. [Class 38 (iv)] A cooker or like heating element 11 is intermittently energized over contacts 5, 6 controlled by an auxiliary circuit intermittently energized over different contacts, whereby the ratio of the make-and-break periods of the contacts 5, 6 may be continuously and finely varied by adjustment of the " fixed " contact 6. The auxiliary circuit may comprise a heater winding 1 about a bimetallic strip 3 and in series with a switch 10, closed whenever the adjuster 8 of " fixed contact 6 is moved from the " off " position, and with contacts 2, 2a actuated, with lost motion, by the free end of the strip. The other end of the strip is carried by an ambient compensator 9. The oscillation of the free end of the strip is transmitted to contact 5 by a lever 4, pivoted at 4a. The adjuster 8 works a cam 7, whereby the contact 6 may be biassed towards, or away from, the contact 5. In modified forms, the auxiliary circuit comprises a solenoid having an oscillating or reciprocating armature driving, through a ratchet and pawl mechanism, a cam which actuates the contacts 5, 6. Other contacts operated by the armature provide for its reciprocation or oscillation. Alternatively, intermittent energization of a resistor may cause the expansion and contraction of a metal rod or tube which actuates the contacts 56. The cooker may have a selector switch providing for series-parallel connection of the heaters as well as for the intermittent energization. Specification 575,945 is referred to.

Title: Improvements in electric driving and controlling gear for planing machines
IPC: B23D7/00
Filed: 1919-03-14
Abstract: 144,782. Electromotors, Ltd., Longbottom, B., and Greenhalgh, E. March 14, 1919. Systems for controlling reciprocating motion.- In an electric drive for planing-machines having one reversible motor only, or one motor for each direction of travel, the starting-resistance is divided into two sections which are connected in circuit in opposite sides of the armature, and at each reversal the connexion between each section and its supply is broken. The single motor arrangement is shown in Fig. 1. The ends of the sections Z, Z<1> of the resistance are connected to the reversing-switch C, C<1> in the mains P, N and to the reversing-switch R', R. The strip con. tacts g, g' of the resistance switch are connected to the motor brushes and the arms G, G<1> are driven by the motor through a clutch H to cut out resistance. At the ends of their travel, the arms G, G<1> operate auxiliary switches to cut adjustable resistances F<c>, F<r> into the field circuit. The arms G, G<1> are weighted or spring-controlled when the clutch H is de-energized. With the switch A operated by the machine to complete the circuit of the coil B<c>, the reversing-switch C, C<1> is closed for the cutting stroke. The main current passes through half the resistance Z, the motor armature, and half the resistance Z'. The field coil E is connected across the mains. As the motor starts up it rotates the arms G, G<1> to cut out resistance, and when this is all cut out the arm G opens the switch S<c> to insert the resistance F<c> in the field circuit. After this the clutch slips and the arms remain still. At the end of the cutting stroke the switch A is operated by the machine; this opens the switch C, C<1> and closes the switch R, R<1> to reverse the motor. The arms G, G<1> being left in their extreme positions include the maximum resistance in circuit, this being twice the resistance included when starting the motor from rest. The motor operates the arms to cut out resistance, and in the extreme position the switch S<r> is opened to insert the resistance F<r> into the field circuit for the return stroke. In a modification, one motor is employed for the cutting stroke and another for the return stroke; the motors have separate field resistances, but the two sections of the armature circuit resistance are common to the two motors. The motors are mechanically connected through the gearing, and the motor not energized is driven in the reverse direction by its connecting-gear.
