Abstract: Embodiments of a personnel basket for attachment to a crane boom include folding sidewall sections; a rear wall connected to the sidewall sections; a front wall in pivotal connection to one of the folding sidewall sections; a floor in pivotal relation to the rear wall; a stalk integral to the rear wall and including a boom connection; and a cam or stop that transmits floor loads to the stalk. Because of the pivotal relationships, the personnel basket is moveable or foldable in a connected or assembled condition between a deployed (unfolded) state and a folded (fully collapsed) state. When in the deployed and folded states, the walls and floor remain connected to the personnel basket, the walls sharing a same orientation, the floor pivoting toward and away from the rear wall between a horizontal and vertical orientation.

Abstract: A crane control system and method which automatically de-rates the maximum capacity of the crane when the boom is located in a first zone located on one side of the truck or in a second zone located on the opposite side of the truck. The control system de-rates the crane without input from the crane operator. The control system may use an inductive proximity sensor located on the base of the boom to locate stationary steel targets located around the base of the boom. The targets approximate the outer ranges of the first and second zones.

Abstract: An injector (10) having a needle (14) which is exposed by a retractable shroud (13). Mounted within the body (11) of the injector (10), is a first interacting piston (30) and cylinder (31) which cooperate to enclose a first space (33) which receives the liquid to be injected. A second interacting piston (26) and cylinder (27) cooperate to enclose a second space (28). A gas under pressure is delivered to the second space (28) to cause movement of the second piston (26). The second piston (26) is attached to the first piston (30) and therefore moves with it. The shroud (13) is operatively associated with a valve (35) to regulate the delivery of the gas under pressure to the space (28) to cause operation of the injector (10). A user of the injector (10) grips the body (11) by means of a handle portion (12) and presses the injector (10) against the skin of the animal. This causes retraction of the shroud (13) as the needle (14) penetrates.

Abstract: An applicator to apply a medication in liquid form to the skin or fleece of an animal. The applicator his a handle to be gripped by a user to move the applicator over the skin or fleece. Rotatably supported by the handle is a roller which is equipped with a cam track. Received within the cam track is a cam follower which causes reciprocation of a piston within a cylinder. The cylinder and piston co-operate to pump the liquid to a nozzle so that application of the liquid is metered in accordance with rotation of the roller.

Abstract: An applicator to inject a cream medicament into an animal, the applicator has a body which receives a cartridge consisting of a reservoir chamber and a delivery chamber, with a piston rod extending through both chambers. The applicator has trig operated means which causes reciprocation of the piston rod to cause delivery of the medicament.

Abstract: A rumen injector to inject a predetermined volume of medication into an animal, said injector having a body with a handle gripped by the user, a cylinder fixed to the body, a piston movably associated with the cylinder so as to define a variable volume space, a needle communicating with said space, and wherein said piston is movable to a cocked position where it is retained until automatically released upon said needle being inserted into the animal a predetermined distance.

Abstract: An injector to deliver a predetermined quantity of liquid into an animal, said injector having a hollow body with a handle, an interacting piston and cylinder mounted within the body and cooperating to define a variable volume working space, an injector needle communicating with said space, a passage also communicating with said space to enable the delivery of liquid thereto, a shroud to selectively cover said needle, and wherein movement of said shroud beyond a predetermined position exposing said needle enables relative movement between the piston and cylinder to eject liquid through said needle.

Abstract: An injector to dispense pellets from a magazine rotatably supported in the injector, the injector has an indexing mechanism which causes indexing of the magazine, with the indexing mechanism being actuated by an injection rod which injects the pellets, and with the indexing operation taking place upon return of the indexing rod to its rest position.

Abstract: A multi dose injector having a pair of interacting pistons and cylinders enabling the delivery of two different liquids into an animal upon the single operation of a trigger.

Abstract: A tape dispenser having a hollow body to receive a supply of medicated tape to be dispensed in predetermined lengths into the mouth of an animal, the tape dispenser is trigger operated and is provided with a barrel along which a delivery head moves, a predetermined length of tape is delivered into the barrel and severed from the supply by said delivery head, which predetermined length is then delivered into the mouth of the animal via the terminal end of the barrel.

Abstract: A rumen injector having a body, an interacting piston and cylinder mounted within the body, a needle fixed to the cylinder, and wherein the cylinder is movable from a rest position to a cocked position and said piston is movable within said cylinder from a rest position to a cocked position so that in use of the injector said cylinder is first released to cause insertion of the needle and then said piston is released to cause injection of a dose into the rumen of the animal.

Abstract: An injector to inject liquid into an animal, said injector being of generally cylindrical configuration and having a pre-loadable piston and cylinder which when operated eject liquid through a needle of the injector, said injector having a trigger movably mounted at one end, which trigger selectively permits relative movement of the piston and cylinder to eject liquid from within the injector.

Abstract: A gun adapted to eject pellets into animals and a magazine to contain the pellets, the gun includes an ejector rod which enters the magazine to eject a pellet therefrom, and an indexing rod which engages the magazine to cause indexing thereof.

Abstract: A drench gun having at least one interacting bore and piston to define a variable volume working space, a liquid exit from the working space, a liquid inlet to said working space, and a dose adjustment mechanism to vary the volume swept by the piston to adjust the dosage delivered by the gun. The dose adjustment mechanism comprises a body plug formed in two halves having a passage extending longitudinally therethrough, a movable sleeve located in the passage to abut the piston to adjustably limit movement thereto, and an adjustor projecting into the sleeve and adapted to rotate around the axis thereof. The adjustor and body plug are adapted to engage the sleeve so that upon rotation of said adjustor said sleeve is moved along longitudinally relative to the piston.

Abstract: A flow control apparatus positionable within the discharge nozzle of a drench gun to control leakage of liquid therethrough by means of a series of holes to increase the surface tension within the liquid adjacent the liquid outlet of the nozzle.
