Abstract: An adjustable sidekick trimmer device (23) having a height that can be set to any deck of a tractor (24) having an adjustable mounting plate (25). The deck belt (14) can be changed without taking the whole system apart upon removal of upper bearing (6) located in trimmer housing (9). Activation of the said device (23) is carried out by pulling a control cable (11), made of steel, suitably connected to that device (23). Pushing a control cable (11) “in” pulls the dual idler pulley (13) disengaging belt (14) from the said trimmer device (23). The acting cable (11) acting as a brake stops belt (14) that runs plurality of cutters (4) and trimmer head (2) when a clutch (10) including a spring (15) is disengaged allowing drive pulley (8) to run freely inside said belt (14).

Abstract: The swingpacer of the present invention is comprised of a power source, integrated electrical circuitry and a speaker which is housed in a suitable cabinet. A separate operable control functions as a mode select which cooperates with the electrical circuitry associated therewith to produce the desired number of tones, with the electrical circuitry including a control of operatively permitting the user to control the time delay between audible signals and to control the duration thereof. Additionally, the electrical circuitry includes a control which permits the user to operably control the time delay between the last audible signal of the previous sequence and the initiation of a new sequence of audible signals. The electrical circuitry is capable of generating a short audible signal prior to the starting of the next sequence which functions as an alert to the upcoming sequence.

Abstract: The buckets of a turbine wheel are formed as a series of equally spaced, overlapping U-shaped passages in the rim of a wheel blank. In the machining operation, an island is left as the inner segment of the curved portion of the U and this is used in combination with labyrinth seals to provide a fluid seal between the inlet and the outlet portion of each bucket.

Abstract: A rotor assembly and methods for securing rotor blades within and removing rotor blades from rotor assemblies. The rotor assembly comprises a rotor disc defining a plurality of blade grooves, and including a plurality of tenons disposed between the blade grooves and defining a plurality of pin sockets radially extending inward from outside surfaces of the tenons; and a plurality of rotor blades, each blade including a root disposed within a blade groove to secure the blade against radial movement, and a blade platform overlaying a tenon and defining a radially extending pin aperture. The rotor assembly further comprises a plurality of locking pins radially extending through the pin apertures and into the pin sockets to secure the rotor blades against axial movement, each pin including a head and a base to limit radial movement of the pin.

Abstract: A turbomachine includes a casing having a rotor mounted therein. The casing includes an assembly with provisions for admitting a cooling medium. The assembly comprises a first member having opposed front and rear spaced, radially extending walls. A baffle member extends radially within a chamber defined by said spaced walls. The baffle member includes a plurality of equally spaced circumferential openings defining a fluid flow path for cooling medium injected into said chamber. If the fluid is in a saturated state prior to its injection into the chamber, the fluid is expanded into a superheated state at the chamber entrance. The fluid is directed by the baffle member to the outer diameter of the chamber, then radially inward through the flow path. The fluid exits from the first member through a circular gap having the top surface thereof defined by the lower inner surface of the rear wall of the first member.

Abstract: A locking mechanism for preventing axial movement of side entry buckets mounted upon a rotor disc. The locking mechanism includes a pin loosely supported within a disc tang, the pin having a recessed shoulder arranged to abut against the platform of a first bucket and an extended section arranged to be received in a complementary slot formed in the platform of the next adjacent bucket. A further mechanism is provided for preloading the pin against the buckets whereby the dampening characteristics of the system are enhanced and balancing of the buckets is facilitated.
