A method of manufacturing a polyurethane compound comprises mixing together a polyol, a polyisocyanate compound and a catalyst and allowing the mixture to cure to form a polyurethane, and is characterized in that the catalyst is a neutral complex of a metal selected from Ti, Zr, Hf, Al, Fe, Bi or Sn and a multidentate organic ligand having: a) a number of anionic donor sites=x; b) a number of neutral donor sites, capable of forming a co-ordinate bond with the metal, =y; c) where x+y=from 5 to 8; d) x is from 2 to 4; e) the ligand molecule is of a size and conformation to enable each of the anionic donor sites and neutral donor sites to form a bond with the same metal atom.

A system for use with a mobile device includes at least one sensor to sense a variable related to tilting of the mobile device and at least one activatable system in operative connection with the sensor. The at least one activatable system increases stability of the mobile device upon actuation/change in state thereof on the basis of data measured by the at least one sensor. A variable related to tilting includes variables that indicate concurrent, actual tilting as described herein as well as variables predictive of imminent tilting. Activatable systems hereof change state upon actuation or activation to increase stability of the mobile device by reducing, eliminating or preventing tilting.

Methods of controlling the brightness of a glow discharge which switches from a low brightness state to a high brightness state a given time after the start of an excitation pulse are described. In the first method, conventional pulse duration modulation produces a dimming ratio much greater than the ratio of duty factor variation. In the second method, a plurality of sets of pulses having different fixed durations but variable repetition rates are employed. In the third method, a plurality of sets of pulses having different relative durations have their pulse durations modulated in synchrony.

A boom H for a vehicle A which carries a working implement K to enable operations to be carried out such as excavation or loading, comprises first (11) and second (10) parts, the first part (11) carrying the working implement (K) and the second part (14) being mounted on a body (B) of the vehicle, the first and second parts being connected together for relative pivotal movement about a generally horizontal axis (A 1), a fluid operated actuating means (18) acting between the first (11) and second (10) boom parts to effect relative pivotal movement at least in one sense of rotation, characterized in that the fluid operated actuating means (18) comprises two relatively movable members (20,23) which operate in tension, one member (20) being pivotally secured to one of the boom parts (14) and the other member (23) being connected via a flexible linkage (24) to the other boom part (11) to enable the two boom parts to be relatively pivoted to include a smaller angle between them than would be possible with a rigid linkage with an actuating means (18) operating in tension.
摘要:
The earth moving machine has a body having a ground engaging propulsion device and a base frame mounted on the ground engaging propulsion device. The base frame is movable relative to the ground engaging propulsion device about a first generally vertical axis. A boom extends outwardly of the body and is mounted on the base frame for movement about a second axis transverse relative to the first axis. The boom has a dipper arm mounted at an outer end thereof for movement about a third axis also transverse to the vertical axis. An excavating implement is mounted at an outer end of the dipper arm for movement about a fourth axis also transverse relative to the first vertical axis. A hydraulic ram is mounted between the dipper arm and the boom to effect movement of the dipper arm relative to the boom and hence to effect movement of the implement towards and away from the body. A counterweight is mounted on the base frame, and elements are provided for moving the counterweight towards or away from the first vertical axis in response to movement of the dipper arm relative to the boom towards or away from the body.

A machine comprises a body (10) having a ground engaging propulsion means (11) and a base frame (14) mounted on the ground engaging means (11), the base frame (14) being movable relative to the ground engaging propulsion means (11) about a first generally vertical axis (V), a boom (30) extending outwardly of the body (10) and mounted on the base frame (14) for movement about a second axis (B) transverse relative to the first axis (V), the boom (30) having mounted at an outer end (36) thereof for movement about a third axis (71) also transverse to the first vertical axis (V), a dipper arm (37), an implement (43) mounted at an outer end (42) of the dipper arm (37) for movement about a fourth axis (T2), also generally transverse relative to the vertical axis (41), a cable (47) secured to the dipper arm (37) and connected to a winch means (50) to effect movement of the dipper arm (37) relative to the boom (30) to effect movement of the implement (43) towards the body (10), a hydraulic ram (38) mounted between the dipper arm (37) and the boom (30) to effect movement of the dipper arm (37) relative to the boom (30) and hence to effect movement of the implement (43) at least away from the body (10), and a counterweight (20a), mounted on the base frame (14), means being provided to move the counterweight (20a), towards and away from the first vertical axis (41) in response to movement of the center of gravity of the machine (10).
摘要:
Selective blocking of some amino groups in a polyamino organic compound having at least one pair of available neighboring hydroxyl and amino groups is effected by first preparing in situ transition metal salt complexes of available neighboring amino and hydroxyl group pairs in said polyamino organic compound, followed by introduction of blocking groups on the non-complexed amino groups and, finally, removing the transition metal cations from the selectively N-blocked polyamino organic compound complex to obtain a polyamino organic compound having selectively blocked amino groups.This process is particularly valuable when carrying out aminocyclitol-aminoglycoside transformations utilizing transition metal salt complexes of cupric acetate, nickel (II) acetate, cobalt (II) acetate or mixtures thereof.
摘要:
A handle system operable in conjunction with a fishing rod and reel has an attachment section and a handle section. An arm of the attachment section is attached to a reel housing. The handle section has an upper handle that is connected to the arm and extends above the reel at an angle less than ninety degrees from the fishing rod.
