Title: Constant-force support hangers, for example, for pipes
IPC: F16L3/215
Filed: 1958-06-06
Abstract: 870,885. Automatic tension control systems. GRINNELL CORPORATION. June 6, 1958 [June 12, 1957], No. 18101/58. Class 38 (4). [Also in Group XXVIII] A constant force support hanger, e.g. for piping 10, comprises a supported member 14, Fig. 1, to which a load is adapted to be applied, anchor means 12 for supporting the member, yieldable means 16 comprising a portion of the supporting structural frame of the hanger through which the member is supported by the anchor means and for providing relative movement between the member and anchor means in response to changes in force applied to the member by the load, means 30, 40 for adjusting the length of the hanger between the anchor means and the load, and means 12 for actuating the length-adjusting means in response to said relative movement to thereby change the length of the hanger to compensate for the said changes in force. As shown, upper and lower plates 12, 14 are connected by tension rods 16, the plate being suspended by rods 20, and a reversible electric motor 24 mounted on the plate 14 carries on the driving shaft 26 thereof a worm gear 28 which meshes with a worm-wheel 30 provided with a screw-threaded opening 38 for the reception of a screw member 40. Also, mounted on the plate 14 is a switch 54, the arm 56 of which is biased against the upper wall 57 of an aperture 57a in an element 58 by a tension spring 59, the element being fixed to the plate 12. Downward movement of the piping 10 resulting from a change in temperature causes elongation of the rods 16 so that the switch is actuated whereby the motor 24 rotates to drive the member 40 downwardly when the force applied by the piping is decreased and the rods begin to contract, such contraction causing the switch to again operate to stop the motor. Conversely, upward movement of the piping decreases the tension on the rods 16 whereby the motor is operated to raise the member 40, such lifting of the member having the effect of increasing the downward force exerted by the piping and elongating the rods; the elongation causes actuation of the switch to stop the motor. In a modification, the screw member 106, Fig. 4, is keyed to the worm-wheel 114 and receives a nut member 122 having depending tension rods 124 supporting a cross-head 128. The switch 144 is actuated by an element 140 secured to the member 122.

Title: Improvements in or relating to internal combustion engines
IPC: F16J1/14
Filed: 1923-07-13
Abstract: 221,911. Invernairn, (W. Beardmore), Lord, and Chorlton, A. E. L. July 13, 1923. Pistons; connecting-rods.- In the piston of an internalcombustion engine of the type in which the connecting-rod engages the whole of the lower surface of the gudgeonpin, the latter is insulated from the piston head. The gudgeon-pin G, which may be spherical, is cut away at the ends to form flat surfaces G<1> held against shoulders E<4> in the piston by studs B<2>. The nuts of the latter are situated in recesses in the piston forming the shoulders E<4>. In a modification, the gudgeon-pin is cut away at the middle and is secured to a central projection in the piston, the connecting-rod end being correspondingly shaped. Heat-insulating layers F<1>, which may be grooved and perforated, are interposed between the gudgeon-pin and the shoulders E<4>, and a pad of insulating material F<2> may be interposed between the head and the gudgeonpin. The piston head E may be detachable, being secured, to the skirt by bolts E<3> engaging slotted lugs E<2>. A heat-insulating layer F may be interposed between the head and the skirt.

Abstract: 671,198. Current measuring. BRITISH THOMSON-HOUSTON CO., Ltd. July 20, 1950 [July 28, 1949], No. 18150/50. Class 37. [Also. in Group XXXV] A Hall plate 1, Fig. 1, is fed with A.C. from a source 7 and is acted upon by the magnetic field of a coil 4 carrying the direct current to be measured and of a rotatable permanent magnet 5; the output of the Hall plate is dependent in phase on which of the two fields from 4 or 5 is the greater, and is applied to a phase sensitive circuit 13 so that either winding 10 or 11 of motor 8 is energized to rotate the magnet 5 until it reaches a position where its field in the plate 1 is equal and opposite to that due to the coil 4. A pointer 14 on the magnet thus indicates the magnitude of the current in coil 4. The motor 8 may rotate the coil 4 instead of the magnet 5.

Abstract: 837,494. Hydro-pneumatic spring units. ROTOL Ltd. June 12, 1958 [June 14, 1957], No. 18865/57. Class 108(3) In a hydro - pneumatic spring unit compressed air in a chamber 26 is separated from hydraulic liquid inside a piston rod 13 by a floating piston 23. The space inside a sleeve 58 and between the piston rod 13 and a cylinder 11 is also filled with hydraulic liquid. In operation, when the unit is extended liquid is displaced from the right of a piston 12 through orifices 34 to the left of the piston 12. Simultaneously the sleeve 58 is pulled to the right by an abutment 56 on the piston rod 13. Consequently liquid in an annular chamber to the left of a partition 35 is displaced through a clearance 73 and slots 57 into a chamber on the left of a closure member 46 and thereafter through an aperture 48 and orifices 53, 54 in a plate 49 into the hollow piston rod 3. This displacement compresses the air in chamber 26. Some liquid also passes through passageways 45 and a plate valve 43 into the chamber to the left of the piston 12. On recoil liquid passes back through small apertures 43a, the plate valve 43 having moved to the left. Also, liquid passing from inside the piston rod 13 through the member 46 causes a plate 49 to move to the left, restricting flow to a central orifice 53. When the unit is contracted, liquid moves through holes 34 from left to right, and liquid passes through the aperture 48 and orifices 53, 54 into the piston rod 13. Air in the chamber 26 is again compressed. A small amount of liquid passes through apertures 43a and passageways 45 from right to left and through slots 56 and the clearance 73 from left to right. On recoil the reverse occurs.
