  • Patent number: 5206805
    Abstract: The system provides an improved clutch control system for use in a continuously variable transmission system. The system provides for generation of a clutch pressure setpoint to re-engage the clutch during special conditions in which the torque created by the vehicle inertia would tend to drive the engine to an undesirable operating point. Clutch slip speed is monitored as a difference value and integrated to provide a gradually decreasing error signal to return the clutch input speed to the clutch output speed, at which time clutch lockup will occur. Additionally, throttle position is monitored and a maximum torque schedule used to provide a maximum torque signal to prevent driver demand from undesirably racing the engine in similar conditions. A filtered output of the maximum torque schedule provides a pressure setpoint signal representative of actual driver demand which may be added to the clutch slip speed error signal to generate the clutch pressure setpoint.

  • Patent number: 4857051
    Abstract: A breastpump is provided with a valve mechanism that closes a collection chamber when a vacuum is applied to a hood member and opens the collection chamber when the vacuum is removed. The valve mechanism is removably attached to the collection chamber for ready cleaning. A baffle in the hood member protects the vacuum line from milk flow. One embodiment of the invention has a connecting sleeve for connecting either a manually driven pneumatic pump or a motor driven pneumatic pump to the hood body to create an intermittent vacuum. A connector is further provided for use with a pair of breastpumps operated simultaneously by a motor driven pneumatic pump. An adjustment piece for decreasing the cross-sectional area of a funnel-shaped hood member is also disclosed for use of the breastpumps with smaller breasts. One type of manually driven piston pump useful with the invention has apertures formed through the pump cylinder wall that are selectively opened and closed for adjustment of the piston pump vacuum.

  • Patent number: 4856250
    Abstract: A sleeper is disclosed comprising a guideway, a resilient strip, a nailing bed and a spring. The guideway is an elongated channel of C-shaped cross-section with three fully closed faces and a partially open face. A plurality of the guideways are fastened to the floor base and the resilient strips placed in the bottom of the guideways. The nailing bed is an elongated wooden element with an elongated protrusion. The nailing bed defines an inverted T-shaped cross-section and is placed in each guideway above the resilient strip. The protrusion of the nailing bed extends through the partially open face for attachment to the flooring material. The nailing bed is shorter than the guideway to leave sufficient room within the guideway at at least one end of the guideway for the spring. The spring is inserted with one end against the end of the nailing bed. The spring is then compressed and a stop inserted through the guideway to maintain the spring in the compressed condition.

  • Patent number: 4854792
    Abstract: A system and method for bracing and cushioning the impact of movable massive loads during sudden deceleration of a transport vehicle, such as created during humping of railway cars. Resilient elastomeric pads separate adjacent objects of the load with the thickness and density of the elastomeric material chosen to dampen typical impact forces without damage to the objects. The resilent pads are preferably formed with at least one face contoured to envelope the side of an object. Three types of resilient pads are disclosed for use in transporting massive sheet metal coils with one pad adapted for particular use at endwalls, another pad for use between coils, and yet another pad for use between mid-row coils and doorway dunnage.

  • Patent number: 4852029
    Abstract: An automated method and apparatus for grading pre-cut lumber products according to selected physical properties thereof such as modulus of elasticity (MOE) and modulus of rupture (MOR) are disclosed. A conveyor transports boards to be graded to an automated lumber feeding mechanism which sequentially rotates each board from a loading to a grading position. In the grading position, an impactor impacts one longitudinal end of the board to generate a compression force and a detector at the opposite longitudinal end converts the compression force to an electrical signal. Data acquisition circuitry samples and stores at least one cycle of the signal and a computer analyzes the samples and assigns values to predetermined parameters which characterize the signal. The computer utilizes the parameter values in one or more predetermined formulas which are optimum statistical predictors of the selected physical properties as a function of the parameters to obtain values for the selected physical parameters.

  • Patent number: 4851264
    Abstract: A process for reinforcing porous refractories with fillers, such as carbon particles, is provided. First, filler particles are mixed with a liquid resin to produce a liquid mixture. The mixture is allowed to seep into the pores of the refractory, preferably by immersing the refractory in said mixture in an evacuated tank. The refractory can be removed from the mixture and excess mixture can be allowed to drip from the refractory. The refractory is then cured, preferably by heating. The refractory is strengthened by the process to better withstand heat fluctuations encountered, for example, in the steel refining process.

  • Patent number: 4846518
    Abstract: A gripping device for a doll's extremity has a holder, resilient material retained in the holder, and a handle. An object is pushed into a slot defined by the resilient material. The resilient material grasps the object and retains it in the holder. The handle is integral with the holder and allows the gripping device to be attached to a doll's extremity, such as a hand. This gives an observer the impression that the doll is actually holding the object.

  • Patent number: 4841608
    Abstract: Capacitor bodies are usually carried in open ended containers. The open ends are then closed with a cover or capacitor top after the capacitor body is inserted in the container. Electrical leads are then attached to terminals carried by the capacitor top. Prior art methods of forming such tops involved insert molding. The present invention starts with a preformed plastic disc with two apertures for terminals and a boss for positioning lead attachment. The terminals and a positioning lead are then applied to the disc through a combination of riveting and ultrasonic swaging.

  • Patent number: 4841696
    Abstract: A window insert assembly is disclosed having a spring-biased frame construction used to secure the insert within existing window frames of varying size. The insert assembly is particularly useful for mounting interiorly of an existing window pane to form a "double pane" insulative window structure, i.e., by creating a thermal cavity between the interior side of the existing window pane and the window pane of the insert. The insert assembly comprises a solid pane, such as a glass pane, mounted in a first frame. The first frame is received within a second frame which has movable sides for changing the size of the second frame. Springs are provided between the second frame and the first frame, preferably on all four sides of the rectangular window insert assembly, which bias the second frame outwardly relative to the first frame. The size of the second frame is adjustable by pressing one or more sides against this bias to fit the insert within an existing window frame in which it is to be installed.

  • Patent number: 4842250
    Abstract: An earth drilling machine includes a crown block assembly, a travelling block assembly and a drawworks. The drawworks includes a drum which rotates about a drum axis. The drum axis is oriented at right angles to a fast line plane defined by a fast line sheave included in the crown block assembly. In this way, the fleet angle between the drum and the fast line sheave is kept substantially equal to zero. Various sheave arrangements are described which combine proper selection of sheave pitch diameter, sheave axis angle, and sheave placement to ensure that the fleet angle of all of the sections of line extending between the crown block assembly and the travelling block assembly are reeved with a fleet angle exactly equal to zero. In this way line wear is reduced and the height, weight and windage of the mast are all minimized.
