Title: Improvements relating to frames for railway vehicle trucks
IPC: B61F5/52
Filed: 1937-08-24
Abstract: 489,073. Railway-vehicle undercarriages; dash-pots. BUGATTI, E. Aug. 24, 1937, No. 23212. Convention date, Aug. 24, 1936. [Classes 103 (vi) and 108 (iii)] In a railway-vehicle bogie of the kind in which two side-frames are flexibly connected to a transverse frame member, resilient means are incorporated in the frame tending to maintain the members in a normal, non- distorted position. In the construction shown in Fig. 1, a tubular transverse member 1 is fitted at its ends with arms 44 carrying pins 45 which engage within resilient sleeves 46 of rubber or like material inserted in apertures in the side-frames 2. The vehicle body may be supported on side-bearings at the midpoints of the frames 2, while the member 1 may have a central aperture to receive the king-pin, the movements of which may be additionally controlled by a dash-pot incorporated in the member 1. Thus, as shown in Figs. 2 and 3, the cylinder 1 is formed with integral upper and lower flanges 3 providing flat surfaces, on the upper of which are disposed two side-bearings including seats 4, slides 5, rollers 36 and convex curved plates 6. The king-pin 21 passes into the interior of the cylinder 1 and is provided at its lower end with a ball 19 co-operating with a divided thrust sleeve 20 and an hydraulic dash-pot. Dash-pots. Built into the cylindrical portion of the member 1 is a pair of cylinders 11, 12, which are provided respectively with apertured pistons 22, 23 co-operating with fixed rods 28 of variable cross-section, the inner ends of the cylinders 11, 12 being interconnected by pipes 33 and a reservoir 34. The piston rods 24, 25 are directly actuated by the ball 19, while between the sleeve elements 20 and the cylinders 11, 12 are disposed springs 17, 18 each contained within a pair of cages 13, 14 and 15, 16 capable of relative movement. If, for any reason, the body tends to move, say, to the left, relative to the truck frame, the piston 22 will be displaced in the cylinder 11 against an increasing resistance, while the piston 23 will move with comparative freedom, the entrance of the piston rod 24 into the cylinder 11 effecting a transfer of fluid via pipe 33 to the cylinder 12. At the same time the spring 17 is compressed and subsequently assists in restoring the parts to a central position. The pistons 22, 23 may be fitted with relief valves 26, while the resistance of the shock-absorbing cylinders may be adjusted by altering the position of the rods 28.

Title: Improvements in locking devices for suspended electric lamps
IPC: H01R33/97
Filed: 1935-08-19
Abstract: 453,724. Electric couplings. AKTIESELSKABET ELEKTRISK BUREAU, 17, Middelthunsgate, Oslo, Norway. Aug. 19, 1935, No. 23252. Convention date, Aug. 23, 1934. [Class 38 (i)] A device for locking the coupling parts of suspended electric lamps comprises a bimetallic strip which maintains the coupling locked while current is passing through the lamp. In the example the bimetallic member consists of two limbs 21, 22 connected at their lower ends by a bridge 25 which is provided with a recess 26 to receive a lug 10 on one part of the coupling. The upper ends of the limbs 21, 22 are secured to the other part of the coupling by screws 23, 24 which form terminal connections for current leads connected so that a part or the whole of the lamp current passes through the bimetallic strip which moves to engage the lug 10 within the recess and prevents relative lateral movement of the coupling members. In a modification the current passes through a heating-coil surrounding the bimetallic strip.

Title: Relaxation oscillator
IPC: H03K7/08
Filed: 1974-05-24
Abstract: 1465540 Relaxation oscillators; pulse modulation circuits RCA CORPORATION 24 May 1974 [1 June 1973] 23300/74 Headings H3T and H4L A transistor relaxation oscillator of the type in which a capacitor connected to one input of a comparator charges until its voltage reaches a reference level applied to another input whereupon it causes a reference level to be reduced and a capacitor to be discharged until the lower reference is reached has various textures including the switching between charging and discharging being delayed with respect to the switching of the reference level so as to avoid the circuit locking up. As shown, a capacitor 10 is charged from a constant current source 512 until the voltage is applied to one base of the comparator 531, 532 exceeds the voltage at the other base. The balance to unbalance converter 537, 538 thereupon switches on a transistor 541 and this lowers the reference potential at the base 532 and operates a switching circuit 555, 521 to switch on a current mirror 523, 524, 520 to discharge the capacitor. The discharge continues until the comparator switches at the lower reference potential restoring the reference level and initiating a new charging cycle. The biasing of transistor 555 is such that switching occurs approximately midway between the upper and lower levels of the switching signal at its base so that, as the switching signal has sloping sides, switching is effected after a time delay with respect to the beginning of the changeover of the comparator. The charge or discharge thus continues during the change of reference level and lock-up is thus avoided. The upper reference level is set at about four diode threshold voltage levels (4Vbe) by the voltage drop across the diodes of transistors 545, 546, 551 and 552, the diodes being forward biased by current from a current mirror 510, 507, 508, and the voltage level is stabilized by feedback through 551, 552 and 554. The lower reference level voltage is produced when 541 is conducting and thus 545 and 546 back biased. The level has a value 1À5Vbe (when 551 becomes saturated) and is the sum of the Vbe of 552 together with a voltage 0À5Vbe across 553 (553 being half the value of 516). An output transistor 560 is driven at its base from a point connected to the collectors of the series transistors 542, 522 one or other of these transistors being conducting depending upon the state of the circuit. Transistor 549 is provided to pass a small discharge current for the base of 551.  The design of the current mirror source 50 is described. It is also explained how, by controlling the current supplies to the right and lefthand halves of a modification of the circuit of 50 (Fig. 6, not shown) the frequency or period may be varied in proportion to the control current. Charge and discharge of the capacitor may be non-linear.

Abstract: 1,039,815. Resiliently mounted seats. MASSEY-FERGUSON Inc. June 11, 1963 [June 18, 1962], No. 23304/63. Heading A4U. A vehicle seat is mounted on a parallelogram linkage which has a first link connected to the seat by a second link unfoldable from the seat to alter the configuration of the paralleogram linkage so that the seat 10 may occupy two seating positions as shown in Figs. 1 and 5 respectively. In the normal position (Fig. 1) the seat 10 is resiliently mounted on arms 54 and guide links 44 which form a parallelogram linkage and have a torsion spring 90 disposed about a shaft 58 with one end 92 of the spring engaging an arm 54 and the other end 94 co-operating with a tension adjusting device. The tension of the spring 90, and thus the vertical position of the seat, is adjusted by rotating a screw 100. The correct adjustment for an occupied seat is indicated when a pin 106, secured to a link 44, is aligned with a pin 108, secured to a housing 24 of the vehicle. Vertical movement of an occupied seat is limited upwards by an extension 60 of an arm 54 abutting a resilient bumper 64 mounted on the vehicle, and downwards by a resilient bumper 88 contacting the vehicle. The seat 10 also has a vibration dampener comprising relatively reciprocable members 78, 80. In order to move the seat to a raised seating position (Fig. 5), the front of the seat 10 is lifted so that links 44 pivot anti-clockwise about their connections 46 to housing 24, and a saddle member 72 pivots about its point of attachment 66 to arms 54 and away from the bottom of the seat 10. When the seat reaches its raised position it is locked in position by links 44 abutting stops 52, by legs 70 of the saddle member 72 resting on flanges 20 of the vehicle floor, and by stops 74 engaging arms 54.

A device for converting a continuous rotary movement of a shaft 1 into movement of a toothed output member 26 in dependence on electrical signals comprises a rotor 16 secured to input shaft 1 and having a plurality of operating rack members 19 arranged in radial slots 17, a plurality of tappets 20 pivotally secured to the operating members 19 by balls 25, fixed face cams 32 adjacent the ends of the tappets 20, and electromagnets 11, 12 for selectively tilting the tappets 20 in order that they may be operated upon by one of the face cams 32. As the rotor 16 rotates, the tappets 20 move past the poles of the two electromagnets, and if neither electromagnet is energized no movement of output member 26 takes place. If, however, one of the electromagnets is energized, the tappet passing by it pivots theretowards, whereupon the tappet engages the cam 32 and causes the rack 19 to be shifted laterally by one tooth before it engages in the wheel 26. Whilst the rack is engaged with the wheel it is moved back to its initial position thereby causing rotation of the wheel 26 by one tooth. The output wheel 26 may comprise a helically toothed wheel or a rack. In a modification, racks 41a, 41b, 41c, 41d, Fig. 12, adapted to engage an output wheel, are located between actuating elements each comprising a tappet 44 juxtaposed with a guide-plate 45. Levers 49 are pivotally mounted on the racks and have rounded ends which engage apertures in adjacent plates 45. In another modification, tappets 80 have lateral racks 81 meshing toothed wheels 82 pivotally mounted on racks 83 cooperating with the output wheel. Alternatively, the connection between the drive elements and the actuating elements can take the form of cables, bands, chains or rollers. In a further modification, a rotor 95 carries a plurality of pivotally mounted plates 99 having toothed ends 100 which, on passing below magnetic cores 102, 103, are selectively directed from a central cam groove 109, Fig. 21, to a side groove 110, or 111. A tilted plate 99 is returned by the cam grooves to its initial position as the opposite end, having a tooth 101, engages a gear-wheel 112 or 113 on a corresponding output shaft.
