摘要： Water pressure is monitored in a system. A first condition is detected when the water pressure has dropped below a predetermined value. In response to detecting the first condition, additional water is introduced into the system. A second condition is detected when said first condition has been detected as occurring for too long or occurring too often. Water is prevented from being introduced upon detecting the second condition.

摘要： Apparatus configured to be incorporated into a fluid transport system for adding material to the transported fluid comprises a main channel to provide a passageway for flow of said fluid and a side channel supplied with secondary fluid in communication with the main channel. Flow of fluid in the main channel causes the secondary fluid to be drawn into the flow and mix with the main fluid. Used in cleaning central heating systems for adding a dosing material (e.g. cleaning fluid or inhibitor) to the heat transfer fluid. A housing 302 receives a Hall Effect flow measuring turbine 313 with display 202, an injector 312 with central secondary fluid bore and multiple main fluid bores, a bottle adapter 201 and a cam operated check valve 310. The housing is connected to the system via quick release couplings 301, 305 and a hose 306 and a bottle of dosing material is connected to the adapter.

摘要： 665,464. Springs. DUNLOP RUBBER CO., Ltd., and SEDDON, R. M. Aug. 18, 1949 [Aug. 31, 1948], No. 22876/48. Class 108(iii) A shock absorber comprises relatively axially movable coaxial inner and outer members, a plurality of annular resilient members axially disposed on the inner member, means separating the resilient members into at least two axiallyextending sections, and means whereby all the resilient members are compressed when the inner and outer members are relatively displaced in one direction, and part only of the resilient members are compressed for such displacement in the other direction. In the construction shown in Fig. 1 the outer member comprises tubes 5, 11 united by a threaded connection 9. The inner member comprises rods 6, 12 united by a collar 7 which carries a rubber annulus 10. The resilient members 13, 13 1 are located respectively between abutment washers 8b, 8c, and a washer 8a and a closure plug 3 of the tube 5. The washer 8c bears on a rubber anulus 14. In an alternative arrangement, Fig. 2 (not shown), the washer 8a is of smaller diameter than, and slidable within, the bore of the connection 9. The members 13, 13 1 may be unequal in length and may be replaced by a plurality of rubber elements spaced apart by rigid discs of metal or synthetic material. The invention may be applied to towing struts and vehicle suspensions and to the motorcycle, rear wheel suspension described in Specification 665,521, [Group XXXI].

[Class 60] A workholder 1 for grinding or polishing lenses comprises a deformable rubber shell with a surface having the general contour to be imparted to the lenses and a number of depressions 7 each adapted to retain a lens. The depressions are formed with outwardly-dished bottoms 8 and have an aperture less than the lens diameter in order that the lens will be securely held. A flange 2 is provided to hold the workholder on a stationary metal support having a contour complementary to the interior of the workholder. Other forms of holder are described for treating concave and cylindrical surfaces. The rubber may be natural or synthetic.

摘要： 634,111. Springs ; road-vehicle spring- suspensions. DUNLOP RUBBER CO., Ltd., and SEDDON, R. M. Feb. 25, 1948, No. 6082/47. [Classes 108 (ii) and 108 (iii)] A resilient device for a vehicle suspension comprises a cylindrical member 1 having at each extremity a plunger 7 adapted to be associated with a vehicle wheel, compressible and resilient means interposed between the plungers and within the cylindrical member, and means for restricting the movement transmitted by one plunger to the other, to a predetermined maximum. The resilient mass may be a helical spring or compressible fluid but is preferably a stack of rubber discs 2 each having interlocking bosses 2a and depressions 2b, the latter engaging at each end a boss 6 on the face 5 of the plunger 7. The two centremost discs engage respective dished washers 20 the movement of which is limited by an annular stop 23 secured to the member 1. Each plunger 7, which is surrounded by a flared rubber sleeve 8 intended to absorb rebound shocks, is pivotally attached to an arm 10 associated with a wheel. A sheath 13 excludes dirt. The member 1 may form a transverse chassis. member, and the arm 10 may be part of a transverse link suspension, in which case road shocks are transmitted between opposite wheels. Some of the discs 2 may be replaced by rigid discs of wood or metal, or metal plates may be inserted between adjacent discs 2.

摘要： 631,834. Vehicle suspensions; shockabsorbers. DUNLOP RUBBER CO., Ltd., and SEDDON, R. M. May 10, 1947, No. 12696. [Classes 108 (ii) and 108 (iii)] [Also in Group XXXI] In a resilient suspension means adapted to act in compression, two coaxial tubular resilient members 61, 61a contained within two telescopic members 45, 50 surround interengaging guide members 57, 58, while a piston 62 is disposed between the adjacent ends of the resilient members to form two chambers of variable volume; air can flow relatively freely from one of these chambers, but its return thereto is restricted. The tubes 45, 50 are respectively closed by plugs 46, 53, to which are attached the guide means 57, 58, a sliding bush 59 serving as an abutment ' for the resilient column 61. To prevent contact between the guide members and the resilient columns, which are formed of rubber or like resilient material, the former may be surrounded by a helical spring 68, or the bore of each disc comprising the column may be made tub-shaped. The abutting ends of the columns 61, 61a hold between them the piston comprising a cupwasher 64, in the crown of which is a small hole 65. On compression, air can escape freely from the upper tube 45 past this washer and pass to atmosphere through a hole 66 in the lower tube. Rebound is, however, damped as air can only return to the tube 45, through the small hole 65. Two opposed cup-washers may be used, in which case a valve is provided in the wall of the tube 45 to control air flow. The damping effect may be va ried by making this valve adjustable, or by placing the piston washer nearer one end of the telescoping members. Where, as in the case of a motor cycle front fork, two elements are connected in parallel relationship by transverse tubes 41, 42, holes coinciding with opposite ends of one of the bridging tubes may be drilled in the walls of the sleeves 45 and a single valve be provided, either on the tube or the wall of a sleeve 45, to control air flow in both elements. The rubber discs may be reinforced by bonding metal or fabric elements to their end faces; or they may be replaced by a single, or a set of, cylindrical tubes. The guide means may comprise a rod and tube, as shown, or inter-engaging slotted members. The spring may be of streamline shape in cross-section, and. if an elliptical shape is used, a set of guide members is provided at each focus.
