Title: Single steerable wheel suspension
Inventor: TREBILCOCK TERRY NEIL
IPC: B60G11/04
Filed: 1986-02-04
Abstract: A sprung suspension system (10) for a single steerable wheel (76) of a three wheeled sweeper (11) is disclosed which includes wheel supporting elongated swing arms (40) pivoted to a fork assembly (12) about a substantially horizontal axis with springs (52) connected between the rear end of each swing arm and the fork assembly; the swing arms are rigidly secured together at their forward ends by means (90) to prevent independent pivotal movement of the arms relative to each other, thereby maintaining the rolling plane of the wheel substantially normal to the horizontal axis of the fork assembly and thus greatly minimizing tire wear when making sharp turns or driving along rough roads. <IMAGE>
Patent GB-2171941-A (GB)
Title: Treatment of cast iron melt prior to casting
Inventor: ALT ANTON
IPC: C21C1/10
Filed: 1986-02-28
Abstract: The melt is treated in a treatment chamber (4, 5) with an agent (2a) which promotes the formation of spheroidal or vermicular graphite, and is then introduced into a mould cavity (8). The agent (2a) comprises an alloy based on magnesium and/or rare earth metals, and is placed in a recess (2) in the base of the treatment chamber. Above the recess (2) there is arranged a dividing element (3) which acts as a flow resistance and ensures an intense reaction of the melt with the alloy. During the pouring-in process, a pouring gate (7), which communicates the treatment chamber with the mould cavity (8), is closed by means of a plug (6), whereby the melt is dammed-up for a short time before the plug (6) is opened thereby allowing the mould cavity (8) to be filled with treated melt. Thus, the melt is in contact with the agent for a sufficient period until the necessary reaction time has expired and the reaction products separate and a complete blending of the melt is achieved, prior to introduction of the melt into the mould cavity. <IMAGE>

Title: W.C. cistern
Inventor: SOMERFIELD ALAN DAVID
IPC: E03D1/08
Filed: 1987-06-10
Abstract: A WC cistern comprises a vessel (1) containing a fluid conduit of sinuous shape (10, 11 - 14). When the cistern is charged, discharge is prevented by pressurised air locked in part of the conduit (including 15) by a column of liquid (b) located downstream of it within the conduit. A venting tube (25) is operable to connect the air lock region (15) of the conduit with a more downstream region (17) at ambient pressure, and operates thus when a bulb (32) is squeezed to expel liquid from the tube, so initiating a discharge of the cistern. The vent tube (25) may also have a branch limb (50) having an open end (52) located only slightly below the normal full liquid level (6) within the cistern; this feature can operate to prevent initiating a discharge of the cistern by operation of the bulb (32) unless the cistern is at least nearly full. <IMAGE>
