Title: Improvements in or relating to the manufacture of axles and in appliances employed therein
IPC: B21H1/18
Filed: 1922-03-31
Abstract: 199,828. Beaumont, H. March 31, 1922. Shafts.-In apparatus for rolling axles between horizontal reciprocating dies having raised tapered surfaces the bloom is held in and rotated by gripping devices which move axially as the bloom lengthens during the operation. The grippers h are rotated through gearing from a shaft chain driven from a main shaft. The dies are also reciprocated in opposite directions by chain gearing from the main shaft, the parts j, k, m of each die being raised and the part j inclined towards the centre. In operation the bloom is placed on the forward end of the bottom die when the dies are in their " out " position. On inward movement of the dies a rack p engages a pinion q to withdraw a pawl v from a wheel on a shaft x thus allowing the grippers to be actuated by a spring 5 to grip the work. At the end of the movement projections n on the die members engage the surfaces o to withdraw the grippers and release the work. On the return stroke the pawl v is automatically re-engaged with its wheel.

Title: Improvements relating to follow-up apparatus
IPC: G05D7/06
Filed: 1945-04-14
Abstract: 606,959. Electric follow-up systems. BURNS, F. D. April 14, 1945, No. 9374. [Class 40 (i)] [Also in Group XIX] In a follow-up system the primary and secondary members are rigid pivoted levers each carrying one of a pair of contacts which are so connected in the circuit of the follow-up motor that it runs to bring the follow-up contact into contact with the primary contact when the two are apart and in the opposite direction when they are in contact so that the' motor, which actuates a final member through a cam mechanism, hunts about a mean position determined by that of the primary member. Fig. 1 shows an arrangement in which the pressure drop across a perforated plate II in a pipe 10 of a gas flow meter, is applied across a diaphragm 17, dividing a chamber 16, the diaphragm 17 being connected to a spring 30 and a pivoted member 25 by a rod 21 in such a manner that member 25 is displaced in proportion to the pressure drop. Member 25 carries one (44) of a pair of reversing contacts, the other one being carried on a pivotably mounted member 31 driven by a crank 33 connected to motor 38. The contacts are arranged in the motor supply circuit in such a manner that the motor runs to close them when they are open and-vice versa, so that the motor armature hunts about a mean position determined by the position of member 25. The angular displacement of the armature is translated into lateral movement by a follower 50 running on cam 36 associated with motor 38, and mounted on member 46 working on a chart 51. A member 48 associated with member 46 operates an integrating mechanism (not shown). In the arrangement shown in Figs. 2 and 3, the cam member 65, 62 is pivotably mounted at 64 on a member 58 mounted on the motor shaft, and also clamped to the latter member by a member 67. A follower 74 carried by a member 73 operates a pointer 70. The index of the reading primary movement relation may be varied by loosening member 67 and adjusting the cam about centre 64. To ensure that only the correctly profiled cam surfaces are used, limit stops 29, Fig. 1, are provided.

Abstract: 804,417. Deforming ends of helices. WELLS CO., F. L. March 22, 1957 [June 19, 1956], No. 9450/57. Class 83 (4). Apparatus for cutting and forming the ends of helicals used in the assembly of coil-springs for upholstery and bedding comprises a base member, a member movable toward the base for clamping the end portion of a helical against the base, means for cutting the helical and for forcing the cut end portion of the helical into an adjacent turn of the helical. A helical 71, connecting coil-springs 75, is placed in position with its turns seated in grooves 69 in a base 13. A slide 37 is then moved, by fluid pressure means, down a guide, inclined at 10 degrees to the horizontal, on the base 13. On this movement a first rise 61 of a cam 55 engages a roller 35 on a member 27, pivoted at 25 to side supports 17 on the base 13, to rock the member 27 so that its lower end 28 presses on the helical 71 to hold it in the grooves 69. A second rise 65 of the cam 55 then moves the member 27 further so that the helical is flattened and a shoulder 32 of a blade 29 on the member 27 bends the end part of the helical down into a recess 73 so that it clears a blade 67 on the advancing slide 37. The blade 67 then co-operates with a cutting edge on the blade 29 to sever the end part of the helical 71 and then continues to force part of the last turn of the helical downwardly and inwardly of the last full turn. The severed end part of the helical falls from the recess 73 to a receptacle. One such cutting and forming device is provided for each end of the helical.

Title: Improvements relating to aircraft undercarriages
IPC: B64C25/50
Filed: 1950-04-18
Abstract: 673,252. Aircraft undercarriages. TRIGGS, W. W. (Geisse, J. H.). April 18, 1950, No. 9454/50. Class 4. An aircraft has two main wheels positioned one on each side of the aircraft axis, a castor mounting for each main wheel and means for urging said wheels into positions parallel with the aircraft axis, said means comprising stop means for preventing said wheels from nosing inward toward said axis and other means resiliently restraining said wheels from nosing outward from said axis. The aircraft 1 is supported on two main wheels 2 and a nose or tail wheel 10. Each wheel is free to castor and each main wheel 2 is supported in a fork 38 which is attached to the lower element of a resilient shock absorbing unit, of which the upper element comprises a shaft 29 having a lever 50 keyed thereto. Each lever 50 is urged by a spring 52 into contact with a stop 54 rigid with the aircraft structure so that each main wheel is normally held parallel to the longitudinal axis of the aircraft but is free to undertake a nose-out castoring movement only. When the aircraft lands in a cross wind therefore, one main wheel and the tail or nose wheel will castor in the appropriate direction while the other main wheel will be held parallel to the axis of the aircraft by the action of the arm 50 on the stop 54. In the embodiment shown in Fig. 6 each wheel supporting leg comprises a sleeve 27 mounted in a fixed part 25 of the aircraft structure. A bearing 32, clamped between the upper end of the tube 27 and a retainer 28, rotatively supports the shaft 29 which is recessed to accommodate a shock absorbing spring 41. The lower end of the spring rests within a sleeve 35 rigid with the wheel supporting fork 38, the sleeve sliding between the members 27 and 40 and being slotted at 37 to accommodate a pin 36 which is fast with the shaft 29 and limits sliding movement of the member 35. In a further embodiment, Figs. 8-10 (not shown), the lower element of the shock absorbing unit is connected to the upper element by a " jack-knife " linkage which limits the castoring movement to one direction only and in a still further embodiment, Figs. 11, 12 (not shown), each main wheel is supported on a structure in which the effective axis about which castoring action takes place is inclined downwardly forwardly, and outwardly.

Title: Improvements in and relating to electric measuring devices with automatic thermo-electric amplifiers
IPC: G01R17/08
Filed: 1937-04-05
Abstract: 486,247. Non-contact-making relays. SIEMENS & HALSKE AKT.-GES. April 5, 1937, Nos. 9671 and 9672. Convention dates, April 3, 1936 and Jan. 12, 1937. [Class 40 (iv)] [Also in Group XXXVI] Current or voltage measuring apparatus embodying an automatic thermo-electric amplifier, moving-coil instrument and recorder, or other measuring mechanism, has an impedance connected in circuit for the purpose of compensating directly the inertia effect of the amplifier upon the measuring parts. The impedance may be purely capacitative or it can be a transformer connection. In Fig. 1, the current i to be amplified flows through the moving-coil 1, the pointer carrying a vane 2 which sweeps the bolometer wires 3 ... 6 fed from a direct-current source 8. The coil circuit includes a high resistance Rv and low resistance Rn. Across the recorder 7 and resistor Rv is connected a condenser 9. As the current i varies, the time taken for the bolometer to balance due to thermal inertia is compensated by the charging and discharging currents of the condenser 9, these currents being superposed upon the instrument current in correct sense. In voltage amplification the resistor Rv is omitted. In Fig. 5, current amplification is effected through the low and high value resistors 10, 12, and bolometer wires 3 ... 6, the compensation being made by transformer 9 when the mutual inductance of the transformer is approximately equal to the product of resistance 10 and time-constant of the bolometer. Voltage amplification is effected by omitting the resistor 12.
