Title: Improvements in pressure-containing terminal boxes
Inventor: NEWMAN RALPH JACK
IPC: H02G15/06
Filed: 1965-06-11
Abstract: 1,126,361. Terminal box. LAURENCE SCOTT & ELECTROMOTORS Ltd. 10 June, 1966 [11 June, 1965], No. 24859/65. Heading H2E. Fire or explosion due to ignition of an inflammable atmosphere by an electrical fault in a three phase terminal box may be avoided by placing three terminal chambers 26 in a larger pressure-containing vessel. Each chamber 26 can contain the pressure-rise due to a small internal arcing current, but a larger rise causes frangible diaphragm 38 to rupture, placing the interior of the chamber 26 in question in communication with that of the surrounding vessel. Similarly a small pressure rise in the sealing compound 11 which fills sealing box 1 is relieved by expansion against sheets of expanded polyurethane foam, secured to its walls, then by movement into the main terminal box 8. The volume of box 8. is large relative to that of chambers 26, so that the diaphragms 38 of sound; chambers 26; are not endangered.

Title: Improvements in or relating to a fuel control means for a heating system utilizing as the fuel a combustible gas
IPC: F24H3/06
Filed: 1952-10-09
Abstract: 713,611. Controlling gas burners. JETHEET, Inc. Oct. 9, 1952 [Oct. 20, 1951], No. 25307/52. Class 75 (1) In a heating system utilizing a gas burner the combustion products from which are passed through a heat-exchanger, e.g. a warm-air heating system as described in Specification 687,822, [Group XIII], the fuel is supplied to the burner through a valve in an inlet line, a by-pass line is connected downstream of said valve and extends to the outlet side of the heat exchanger, and flow control means including a valve in one of said lines selectively directs gas passing the first valve either to the burner or through the by-pass line. The flow control means may comprise a solenoid operated valve 50, Fig. 2, located between the fuel inlet line 40, a line 23 leading to the burner (not shown), and the by-pass line 48 leading to the outlet flue 36 of the heat exchanger (not shown). The valve 50 is operated by a solenoid 68 in an electrical circuit comprising a switch 72, which may be thermally actuated in response to the temperature of the space to be heated, and a solenoid operating the valve 42 in the inlet line 40. When the solenoid 68 is de-energized a piston 60 within the valve 50 drops so that a passage 62 therethrough connects the inlet and by-pass lines 40, 48, as shown. Thus if the switch 72 is opened any leakage of gas past the valve 42, which should close, is passed to the flue 36. When the switch 72 is closed the valve 42 opens and the solenoid 68 raises the piston 60 so that a passage 64 through the latter connects the inlet line 40 with the burner supply line 23. The fuel inlet line 40 containing the valve 42 may, alternatively, be connected to a Venturi fitting 74, Fig. 3, by a tapered nozzle 82 aligned with an outlet connected with the by-pass line 48, and a lateral outlet connected with the burner supply line 23. The by-pass line 48 contains a valve 84 comprising two chambers 88, 90 separated by a diaphragm 86, the chamber 90 being connected through a line 100 with a conduit 19 through which air is supplied by a blower (not shown) to the burner and the heat exchanger. When the blower is operating the pressure in the chamber 90 maintains the diaphragm 86 seated against an annular partition 98 in the chamber 88 to close the valve 84, so that the gas can pass from the Venturi fitting 74 only through the burner supply line 23. When the system is closed down so that the blower is not operating the diaphragm 86 moves away from the partition 98 to allow any gas leakage past the valve 42 to flow to the outlet flue 36.

Abstract: 1,188,884. Independent front suspensions. A. H. WEIERTZ. 28 May, 1968 [29 May, 1967], No. 25546/68. Headings B7D and B7H. In a front suspension comprising upper and lower suspension arms 14 each connected at one end to the vehicle body 12 for swinging about respective pivot axes and at the other end to a steering knuckle 13 by ball joints 14a defining an axis A about which the knuckle 13 and a wheel 11 mounted thereon can be steered, a resilient strut 15 connected between the body 12 and a rearwardly projecting arm 16 on the knuckle 13 is arranged to transmit to the knuckle a variable force which reduces the tendency for lateral forces acting on the wheel 11 to deflect the wheel from its steered course. The steering axis A is inclined inwardly and rearwardly at the top and is positioned to intersect the ground surface at a point which is spaced forwardly from a vertical line V through the wheel axis by an amount L and inwardly from the tyre tread by an amount D. The thrust line of the strut 15 is inclined inwardly at the top by a greater amount than the axis A and intersects the ground surface rearwardly of the line V. The strut 15 includes a coil spring 22 interposed between flanges 20, 21 on telescoping tubes 18, 19 forming an hydraulic damper. As shown the rearwardly projecting arm 16 is rigid with the knuckle 13 but in another embodiment, Figs. 7-10 (not shown), the arm is part of a member which is mounted on the knuckle for limited rotation about the wheel axis against the resistance of resilient means and carries a brake caliper for co-operation with a brake disc attached to the wheel. Some of the body load may be transmitted to the knuckle 13 by spring means acting on one or both arms 14.

Title: Improved method and apparatus for catalyst activation
IPC: B01J8/24
Filed: 1957-08-14
Abstract: <PICT:0849929/III/1> In a process for activating solid catalyst particles wherein the catalyst is contacted with a stream of inert gas at an activation temperature and at a velocity sufficient to maintain the catalyst in a fluidized state, the stream of gas is maintained in a closed recirculating system, make-up gas is added to the recirculating stream at a predetermined rate and gas is purged from the stream at a rate equal to the make-up gas rate so that a circulation rate may be maintained independently of the make-up and purge rates. Catalyst to be activated, such as chromium oxide impregnated on a silica-alumina base is conveyed to a fluidizing zone 12 of a vessel 11 where it rests on a grid 15 and is fluidized by air from blowers 22 and 22a passing through a line 23, inlet 17 and outlet 18.  Entrained catalyst is removed from the airstream in a disengaging zone 13 of larger area to reduce the velocity of the air. The air from outlet 18 passes through a cyclone separator 19 and is returned by a line 21 to blowers 22 and 22a.  The air stream in line 23 is heated in a heater 41.  Fresh air is brought into the circulating stream through a line 26, and an equal amount of air is purged through a line 24, removing moisture and catalyst poisons. When the air and catalyst have reached the activation temperature (e.g. 400 to 1750 DEG F.) the make-up air is passed through driers 33 and 35.  Some of the air in line 21 is cooled in a cooler 38 before it is passed through bag filters 25 in purge line 24 or through the blowers 22 and 22a, the temperature in line 21 being controlled by a temperature controller 42 which adjusts a valve 44 in a line 39 by-passing the cooler 38.  To obtain a constant air velocity for fluidization, the pressure drop in the fluidizing zone 12 is measured by a differential pressure controller 45, in combination with pressure lines 46 and 47, which regulates a valve 48 in line 23 and blowers 22 and 22a.  Make-up air addition is kept constant by a flow recorder 51 regulating a valve 52, and a pressure controller 53 controls a valve 54 in purge line 24 to stabilize the pressure of the circulating air by purging an amount of air equal to the make-up air. A dew point indicator recorder 59 controls heater 41, so that the activation temperature is maintained until the dew point is below 0 DEG F., preferably below -40 DEG F.  After the catalyst is activated it is cooled while the air is circulated, and is then passed to receivers 62 and 62a.

[Also in Group XXXVII] In a starting system for an internal-combustion engine, of the kind wherein a starting motor a drives a starting pinion through a screw or like connection for effecting engagement with a toothed wheel on the engine and wherein the motor circuit is controlled, through an electromagnetic contactor c, d, by a pushbutton switch e, re-closure of the contactor, until the engine has had time to come to rest, after a false start is prevented by normally closed contacts i, j in series with the switch e and subject to the joint actions of an electromagnet m (also in series with the switch e) which tends to maintain the contacts closed and a thermally responsive element, such as a bimetal strip f, which is heated by the energizing current of the contactor coil a and which thereby tends to open, or allow to open, the contacts i, j. Thus, upon release of switch e after one attempt to start, magnet m is de-energized so that the thermal element opens contacts i, j and switch e becomes effective to initiate another attempt only when the element has had time to cool sufficiently to reclose the contacts, during which period the engine has come to rest. In a modified arrangement, the heat-responsive element is a wire which normally holds the contacts i, j closed against a spring or weight bias tending to open them, the wire being in series with the magnet winding m, the contacts i, j and the push-button e so as to be heated upon closure of the button and to allow the contacts to open for a time when the button is released.
