  • Patent number: 4043590
    Abstract: A sliding roof assembly for motor vehicles or the like in which the assembly is mounted on the exterior roof portion of a vehicle adjacent an opening in the latter for sliding movement between a forward closed position and the rearwardly open position. The sliding panel member is secured in a latched position in which it is firmly engaged with a resilient seal which prevents the entry of moisture or air through the roof opening. In the unlatched condition of the panel it is supported relative to the seal to minimize friction for facilitating easy sliding movement of the panel. A drain system is provided to prevent accumulation of moisture on the upper surfaces of the seal.

  • Patent number: 4041945
    Abstract: A single barrel mixing syringe in which one material such as a liquid is stored in the bore of the syringe barrel and another material such as a powder is stored in a chamber formed in a resilient piston head which forms not only the powder containing compartment but also the seals preventing leakage of liquid from the syringe. The two chambers are separated by a wall which may be displaced in one embodiment by differential pressure during movement of the piston portion of the syringe and in another embodiment by a separate plunger which displaces the wall.

  • Patent number: 4033232
    Abstract: A carburetor has a vacuum operated diaphragm type choke control device that acts in connection with a thermostatic control to permit the carburetor choke valve to be closed during starting but provides a controlled gradual opening of the choke valve after starting. An adjustable stop member permits adjustment of the opening by limiting the extent of movement of the diaphragm. The device includes purge feature for continual self-cleaning of the device. A one-way check valve device and precision by-pass means give exact control of the choke opening.

  • Patent number: 4032003
    Abstract: A conveyor drive system employing a constant speed master drive and a slave drive of the hydrostatic, closed loop type in which there are no electrical or hydraulic feedback lines between the master and slave drive unit. The master drive moves the conveyor at a constant speed as load varies and the slave drive unit responds to changes in load on the conveyor to vary the speed of the drive to maintain a constant pull on the conveyor to insure that the slave drive shares its portion of the load with the master drive.

  • Patent number: 4008506
    Abstract: A portable dock of sectional construction in which adjoining dock sections may be connected together by a pivot arrangement which allows the attachment of one dock section to the other without entry into the water over which the dock assembly is to extend. The pivot arrangement supports the dock section being added for pivotal movement from a prior installed dock section to a horizontal position extending in cantilevered relationship to the prior installed dock section. The pivot arrangement includes supporting surfaces which limit the extent of pivotal movement of one dock section relative to the other and also act to support the added dock section in cantilevered relationship.

  • Patent number: 4000224
    Abstract: A carburetor and fuel feed device for small internal combustion engines incorporating a pumping section which receives fuel from a supply and delivers the required amounts for the range of operation between high and low speed operation with any excess being returned to the source of supply. A control device is employed which permits deceleration from high to low speed operation without flooding by instantaneously preventing the supply of fuel for high speed operation in response to movement of the throttle valve to an idle or low speed position.

  • Patent number: 3998494
    Abstract: A wheel and grease cap combination in which a plastic covered portion on a vehicle wheel is provided with a radially inwardly facing annular groove positioned adjacent to an opening in the wheel for receiving the grease cap and radially inwardly of the bolt circle for receiving bolts to attach the wheel to the axle hub. The groove receives a plurality of attaching means formed on the grease cap which deflect radially inwardly upon attachment and detachment of the grease cap. The attaching portions firmly engage the bottom of the groove to prevent both axial and rotational displacement of the grease cap relative to the wheel.
