Title: Bridge plate counterbalancing device
Inventor: AKERS ROBERT MURREL
IPC: B61D17/20
Filed: 1969-12-12
Abstract: 1,259,716. Counterbalancing devices; vehicle loading ramps. R. M. AKERS. 12 Dec., 1969, No. 60757/69. Headings B8B and B8E. [Also in Divisions B7 and F2] A device for counterbalancing a hinged bridge plate between either two railway flat cars or a vehicle and a loading dock, comprises a lifting arm 18 having a roller 20 engageable with the underside of the plate, the arm being adjustably biased by a helical torsion spring 80 to substantially support the weight of the plate. The lifting arm 18 is cranked and is secured to a sleeve 42 journalled within a housing 10 and spring loaded for rotation about its longitudinal axis, the spring 80 being secured at one end to a hub 52 keyed to the sleeve 42, and at the other end to a hub 54 rotatably supporting one end of the sleeve 42. The hub 54 includes a plurality of holes in its end face for selective engagement with a pair of bolts screwed into an end plate 50 of the housing 10, when the hub is rotated via a wrench socket 118 formed therein, whereby selective pre-loading of the spring 80 is facilitated. Lubricant chambers are formed within the sleeve 42 by partition caps 108, 110 and 64 and by the arm 18, and communicate with bearings 55, 96 journalling the sleeve 42. The housing 10 is secured through brackets 132, 134 to the structure on which the bridge plate is hinged.  In the embodiment of Figs. 7, 8, 9 (not shown), the lifting arm and sleeve passing through the spring are formed from a single length of bar.

Patent GB-611332-A (GB)
Abstract: 611,332. Electrically-actuated valves. ELLIS, L. S. E. (Robertshaw Thermostat Co.). April 26, 1946, No. 12653. [Class 135] [Also in Group XI] In a safety and ignition gas burner control system the manual or thermostatic opening of the main fuel cock 14 first completes at contacts 50, 52, a circuit from the secondary coil of a transformer 56 to the winding 32 of a relay 30 and operates its armature 34 past a latch 42 to close contact pairs 38, 40. As the opening movement continues, the contacts 50, 52 separate and an arcuate switch arm 66 engages a terminal 68 to complete a, burner starting circuit comprising an electrical bridge. One arm of the bridge consists of an igniting coil 22 and the contact pairs 38, 40. The second arm consists of a solenoid coil 17 operating a valve 16 in the supply pipe to the main burner 10 and pilot burner 18. The third arm consists of a resistance element 24 having a positive temperature coefficient of resistance arranged adjacent the main or pilot burner. The fourth arm resistance element 26 is preferably of the thermally-responsive type. The detector arm consists of a thermal cut-out 28 having time-lag operation. A circuit is also completed through the contacts 38 to a coil 48 heating a bimetallic element 46 which, when cold, holds the latch 42 in position. After a time-lag normally sufficient to allow ignition of the burner, the element 46 flexes to allow the latch 42 to be operated by a spring 44 and the contact pairs 38, 40 separate, thereby breaking the circuit to the igniting coil 22 and heating coil 48. The current now passing through the coil 17 will only be sufficient to hold the valve 16 open if ignition of the burner has been effected and the resistor 24 heated thereby.

Patent GB-2041170-A (GB)
Title: Flow control valve
IPC: F02M59/36
Filed: 1979-12-21
Abstract: A flow control valve comprises a valve member 11 slidable in a bore and having a head 23 for cooperation with a seating defined in the bore between a pair of chambers 15, 16. One chamber 15 is in use connected to a source of liquid at high pressure and the other chamber 16 to a drain. The valve member also has balancing surfaces in the chambers 15, 16. The balancing surface in the chamber 16 has a larger area than the opposed area of the valve head and a restricted outlet 19 extends from the chamber 16. Thus in the closed position the valve member is substantially pressure balanced because the pressure in the chamber 16 is low and as the valve member is moved to the open position the pressure in the 16 chamber increases to act on the larger balancing surface to assist the opening of the valve member. <IMAGE>
