Abstract: A coupling for a plow comprising a push beam attachable to a front of a vehicle. The push beam has at least one outwardly-extending plate at each end thereof. Each plate has an aperture extending therethrough. A support frame is provided that is attachable to the back side of a plow assembly. The support frame has two spaced-apart plates extending therefrom, each of the plates having an aperture therethrough. The plates are dimensioned to be positioned adjacent the plates on the push beam with the apertures in the plates being aligned. A locking assembly is provided for locking the support frame to the push beam. The locking assembly is comprised of a pair of axially aligned pins biased outwardly away from each other. Each of the pins has an inner end and an outer end. A linkage connects the inner ends of the pins. The linkage has a first position wherein the pins are retracted toward each other along the axis, and a second position wherein the pins extend outwardly away from each other along the axis.

Abstract: A measuring apparatus comprises a handle 22 having a tape-holder 26? and pendulum 24 attached thereto such that a measuring tape 30 can extend to a variable extent sideways out of the tape-holder with the pendulum hanging vertically downwards. In the preferred embodiment there are two tape holders 26?, 26? which are rotatable on the handle about the axis of the pendulum.

Abstract: The present invention relates generally to a method of modulating T cell functional activity by utilising ?-amino acid substituted peptides and to agents useful for the same. More particularly, the present invention relates to a method of modulating class I restricted T cell activity by utilising ?-amino acid substituted peptides and to agents useful for the same. The method of the present invention is useful, inter alia, in the treatment and/or prophylaxis of conditions characterised by suboptimal T cell stimulation such as that which occurs in some viral infections and in anti-tumour immunity, as well as aberrant, unwanted or otherwise inappropriate T cell functioning such as, but not limited to, graft rejection or autoimmune conditions, the present invention is further directed to methods of identifying, designing and/or modifying agents capable of modulating T cell functional activity.

Abstract: An animal feeder hopper loading system for loading animal feeders in remote, elevated locations. The system contains a hopper for loading feed at ground or truck bed level, and an air movement device coupled with a simple but unique control mechanism for regulating the flow of feed from the loading system hopper to a flexible hose which discharges feed into the receiving animal feeder hopper.

Abstract: Biodegradable polyesters derived from hydroxy alkenoic acids may be plasticised with an esterified hydroxycarboxylic acid which has at least three ester groups, at least some of the hydroxy groups being esterified with a carboxylic acid and at least some of the carboxy groups being esterified with an alcohol and/or phenol.

Abstract: NH.sub.4 Cl is used as a nucleating agent to prepare polyhydroxyalkanoate compositions.

Abstract: Certain hydroxy alkanoate polymers, such as 3-hydroxybutyrate polymers, when obtained by solvent extraction from fermentation masses, can have long cycle times during thermal processing due to a low rate of crystallization. A combination of (a) an organophosphonic or organophosphoric acid or ester with (b) an oxide, hydroxide, or carboxylate of a metal of Groups I to V is an effective nucleating agent.
