Patent AU-555318-B2 (AU)
Title: Polyurethane
Inventor: GOLDWASSER DAVID JAY
IPC: C08G18/65
Filed: 1982-10-12
Granted: 1986-09-18
Abstract: Polyurethane resins are described having high impact strength and other structural strength properties, and significantly improved resistance to deformation by heat. The properties of these materials are such as to make them comparable to engineering thermoplastics such as nylon and like materials commonly used to fabricate structural components such as automotive parts, equipment housing, sporting goods, furniture, toys, household and like consumer goods. The resins are prepared from organic polyisocyanates, an isocyanate-reactive material (polyol, polyamine, etc.) having an average functionality of at least 1.9, a Tg less than 20 DEG  C. and molecular weight of 500-20,000, and one or more low molecular weight extenders the major distinguishing feature being the markedly lower proportion by weight (2 to 25 percent) in which the isocyanate-reactive material is employed as compared with polyurethane resins conventionally prepared in the art. Depending upon the particular combination of reactants employed the polyurethanes of the invention can be thermoplastic or thermoset and can be prepared in both cellular and non-cellular form.
Patent DE-1916410-B2 (DE)
Title: Electrical component with springy contact connectors - uses springy contact strips for mechanical fixing of component in recess
IPC: H05K3/30
Filed: 1969-03-31
Abstract: the electrical component is held in the recess of the PWB by springy contact strips of the component. The springy can strips make contact with the printed lines on the PWB and can be soldered. At least some of the contact strips of the component are in the form of leaf springs with a camber. The cambers have the purpose to hold the component mechanically springy in the recess of the PWB. The component has at least three contact strips with camber in the same plane. The cambers of a first group of contact strips point in one direction and those of a second group in the opposite direction. The number of cambered strips in each group is the same or nearly the same and they are further evenly distributed. The number of cambered contact/connector strips should be only as large as is necessary to secure springy fixing of the component on the PWB.

Title: Dishwasher conveyor clearing mechanism - has plates fed to drum with tipping bars which overturn plates for water jet application
IPC: A47L15/24
Filed: 1969-11-07
Abstract: The cleaning machine for a dishwasher has the dirty plates passed from an endless band to a transporter chain (4). On the transporter chain, the plates (10) are held between spacer bars (5). The chain passes between the plates of an over turner drum, in which the plate rim is caught by support angles (7) and upper rods (8) turn the plate over. During this operation, the plates are cleaned by water jets (12) which wash the leftovers into a container beneath the machine. The over turned plates are then replaced on the second half of the transport chain. At the end of the transport chain the rim of the plate is gripped between the fingers (10) of a double barred band (11). These fingers (10) grip the plate and lift it into a standing position to drain before stacking.

Patent DE-1960443-B2 (DE)
Title: Pipe or container sealing cap - has internal rotary spring disc with sealing portion actuated by internal pressure
IPC: F16J13/12
Filed: 1969-12-02
Abstract: The sealing cap for containers or pipes has a seal freed of friction during rotation. Internal pressure increases the pressure on the seal via an intermediate rotary disc, centrally mounted inside the cap and acting as a spring by its outer edge against the seal bearing against the edge of the opening. A spring disc (1) has a sealing disc (3) underneath it, combined with it into a single part, and rotates on a central mounting inside the cap (2). When the latter is tightened down, the spring portion 1', 1", 1"') is held clear of the cap apart from at the centre, and is thrust against it in the axial direction under internal pressure. This correspondingly increases the sealing pressure at the edge (') against the container or pipe.

IPC: B65B69/00
Filed: 1991-02-19
Abstract: An apparatus for opening plastic bags to remove their contents has a pair of wheels (11,12) mounted in approximate coplanar relationship such that there is a point of approximate cotangency. The two wheels rotate in opposite directions, and a series of tines 13 are mounted in spaced relation on the periphery of each wheel to extend normal to the direction of travel of the loop. Once a filled plastic bag is placed onto the apparatus at the point of approximate cotangency of the wheels, a biased flexing structure presses the bag against the tines. A hole is created in that surface riding on the tines as the tines move away from the point of approximate cotangency. To remove any articles remaining in an opened bag, a pair of oppositely-rotating rollers (63,68) are positioned so as to draw the bag between them. An oscillating member forward of the rollers acts to prevent any articles remaining in an opened bag from entering between the rollers. A vacuum collection means 73 draws off the emptied bags. The apparatus has particular application to the opening of bags containing recyclable articles. <IMAGE>

IPC: F16D65/18
Filed: 1978-05-09
Abstract: PURPOSE:To eliminate oil pressure pipings exposed to the outside, by building an oil pressure generating machine in a shaft that oscillation supports a caliper. CONSTITUTION:A support shaft 9 piercing a hole portion 10a of a fixing portion 10 penetrates a hole portion 4a of a caliper 4, and supports the caliper 4 in an oscillation-possible shape. When right pulling a rope 21 interlocking with a braking functioning lever, a piston 14 smoothly fitted into a cylinder 13 right moves, and oil pressure is generated in an oil chamber 22. Oil pressure reaches the inside of an oil pressure functioning cylinder in the caliper 4 through a flow path in the caliper 4, thus working a disc brake. Since an oil pressure generating machine is built in the support shaft 9 as a fixing body, the trouble of the failure of oil pressure pipings can be eliminated.
