A kit for assembling timbers into a play structure is disclosed. The kit includes a frame bracket which has a frame segment joined at a right angle to a beam segment. The frame segment has four nail or screw holes and the beam segment has two nail or screw holes. The beam segment has a square bolt hole for receiving a carriage bolt. The frame segment is adapted to joining two timbers into an A-frame so formed to a transverse overhead laminated beam. The kit also has a frame brace with a body pla...

A door latch formed of transparent elastic plastic is disclosed. The latch has an elastic plastic band with a base segment adapted for mounting on a door and a catch segment flexibly attached to the base segment and extending angularly outward therefrom to project transversely beyond the base segment. The band also has a striker segment flexibly attached to the catch segment and extending angularly outward therefrom and transversely to a position outlying the base segment, and also a return port...

A plastic latch for latching a first surface to a second, substantially coplanar, surface is disclosed having a flexible plastic band with a planar attachment segment adapted for attachment to the first surface, an upper arcuate segment extending upwardly from the attachment segment, a planar first segment depending from the upper arcuate segment and substantially parallel to and longer than the attachment segment, a lower arcuate segment extending from the flex segment beneath the upper arcuate...

A flexible reclosable thermoformed thermoplastic container is disclosed which has a base with side walls and a peripheral shoulder extending from the side walls which has a downwardly depending rim. The cover of the container has peripheral edges with depending side walls and is preferably attached by an integral hinge to the base. The cover is adapted to close upon and cover the base. A locking tab with two opposed faces spaced to fit between the base rim and side walls is connected by an integ...

An improved water seal blancher which utilizes a substantially steam proof chamber to subject a particulate food product to a continuous, controlled temperature treatment in steam, and which utilizes a minimum of moving mechanical parts to transport the food product into and out of the steam chamber, includes a base which is adapted to contain a conveyor apparatus for conveying food product through the steam, a cover which effectively closes the tank to form a steam-tight chamber, a feed tank in...

A testing device (11) is applied to an acceleration shock sensor (10) of the type having a reed switch (24) that operates such that the net mass of a magnet (40) is accelerated against a spring (50) upon vehicle impact or rapid deceleration of the vehicle. The change in magnet (40) position causes a change in the magnetic field that activates the reed switch (24). The testing device (11) includes an electromagnetic coil (90) mounted in an area of minimal reed switch (24) sensitivity. The electro...

The position and movement of cows in a herringbone type milking parlors is controlled with a brisket bar apparatus having a barrier which extends along the length of the milking parlor at the height of the brisket of the cows to hold the cows in their proper position within the milking parlor during the milking operation. The brisket bar barrier can be formed of sheet metal having sloped surfaces facing the cows so that no sharp edges or corners are presented to the cows on which the cows could ...

A magnetic refrigeration apparatus (10) is modular in design, so that housing modules (14) are alternately stacked with superconducting magnet pairs (24). Each module (14) has a wheel (16) that is rotated through the module (14), the wheel (16) having cutout regions (18) into which elements (20) of magnetic material are inserted. Each cutout region has two elements (20) separated by a wave spring, the wave spring biasing the elements (20) against the housing module (14) so that the elements (14)...

A surgical cutting tool which may be used in cutting away protruberances from the skin of an individual includes a thin flexible blade including two side margins and a front margin which is keen-edged, and two finger grips which each include an engagement surface affixed to and extending along one side margin of the blade, and an outwardly facing gripping surface so that the tool can be held by the finger grips and thereby safely, easily and comfortably bent into an arcuate shape for cutting, by...

A newspaper bundler (9) having a container portion (10) formed of a unitary paperboard blank for holding the newspapers (310) to be bundled in regular arrangement, a gripper ring (50) to firmly grasp and retain a ball of string (300), a string magazine portion (11) formed of a second unitary paperboard blank to facilitate dispensing of the string into the container portion prior to the insertion of the newspapers. The bundler has string fasteners (42, 44, 46) which retain the string about the ne...
