Abstract: An air weapon comprising a hand grip and a generally tubular-shaped housing connected thereto having front and rear ends confining a tubular pressure chamber. The pressure chamber is of non-cylindrical configuration thereby providing a pressure chamber of increased volume over that obtainable with a cylindrically shaped chamber without detrimentally affecting the external appearance of the weapon. A cylindrical barrel for discharging a projectile from the weapon is positioned within and coaxial to the pressure chamber. A piston conforming to the configuration of the pressure chamber and adapted to move within the pressure chamber along its axis surrounds the barrel with its piston head facing the rear end of the housing. A piston spring also surrounds the barrel and is positioned against the piston head at one of its ends and against the front end of the housing at its other end.

Abstract: An amusement device which has a substantially spherical configuration, and which is formed from a large plurality of floppy, elastomeric filaments that radiate in a dense, bushy manner from a central core region. The filaments are sufficiently floppy to collapse on impact, thus to absorb enough energy to avoid any tendency to bounce. They are also sufficiently dense and floppy that they tend to quickly thread their way between the fingers of a user on contact with the hand. These features promote sure and quick capture of the device during the act of catching.

Abstract: A sod laying machine having front rear sections articulated together. A boom on the front section has arms extending forwardly, with gripper arms extending downwardly from the boom to grip a roll of sod. A control roller connected to the boom arms drives the sod roll to control its speed of unwinding. The sod roll has its grass side facing outwardly and its top unwinds rearwardly so an operator in a seat at the front of the machine, between the boom arms, has an unobstructed view of the critical area of sod extending in the air from the roll to the ground, to reduce the likelihood of buckles and tears therein. The machine passes over the sod after it is laid, to roll the sod.

Abstract: An amusement ride is provided, of the type that moves and tilts passengers viewing a motion picture, which is more versatile than prior rides. A plurality of passenger-holding frames is provided, that are all moved in sychronism, each by a separate set of actuators, while the passengers view a stationary screen. The passenger-holding frame is pivoted up and down on a beam which is supported by only two largely vertical actuators, while two pairs of links or arms limit movement of the beam.

Abstract: The present invention comprises a pair of cuff assemblies for the adult and child and an interconnecting strap assembly, all three assemblies being made of the same material which is an extensible fabric band similar to the extensible material used in waist bands for women's skirts and slacks. Other than size, the two cuff assemblies are identical in structure. Loop and pile locking material is used for setting the correct length of each cuff and is placed on the interior of the cuff of that when the cuff is in place, the loop and pile locking material closure is inaccessible. The use of the loop and pile locking material also provides an inextensible portion of the cuff which will prevent the cuff elongated when in place to slip the hand of the wearer out of the cuff.

Abstract: A recreational device for producing the thrill of a series of consecutive free falls, which includes a housing, a shock absorbing cushion throughout the bottom of the housing, an inwardly extending peripheral deck near the top of the housing arranged to provide a launching platform for allowing persons to jump into the housing, and a plurality of horizontal planar non-woven nets of elastic bands arranged at different levels within the housing with each net spanning the whole horizontal cross-section of the housing. The elastic bands are randomly arranged within each individual net so as to leave spans between the bands which are insufficiently small to prevent a person from passing through the nets without bouncing on each consecutive net, the elastic bands having an elasticity sufficient to permit persons to manually space the bands to jump from a higher net of bands to a lower net of bands.

Abstract: An hydraulic circuit includes a master cylinder and at least one slave cylinder connected in series circuit. An auxiliary discharge conduit with a solenoid-actuated valve is provided to selectively permit the master cylinder to extend its full useful range after the slave cylinders are fully extended. Under normal operation the valve is closed so that the cylinders may extend together. When the slave cylinders reach full extension, the main control valve is kicked out of its detent and the system locks up in that position. If the operator wants the master cylinder to extend further to a second limit position, he opens the solenoid-actuated valve and again operates the main control valve to extend the master cylinder. The system insures that the main control valve will be released from the detent position when the slave cylinder is fully extended at the first limit position of the master cylinder.

Abstract: A shank mounting arrangement for a disk hiller or similar implement which provides simple and precise angular adjustment of the shank independently of vertical adjustment. An upright slotted tube is fixed to a support beam and an upright apertured shank is slidably received in the tube. An adjustable collar including a plurality of holes adapted for alignment with the slots in the upright tube is mounted for rotation with respect to the upright tube, and a pin is inserted through the holes, slot and an aperture in the shank for retaining the shank in a preselected one of a plurality of vertical positions relative to the support beam. The collar may be rotated independently of vertical adjustment to change the angle of the shank.

Abstract: An apparatus for detecting unintentional urination by a user includes an elongated belt of a liquid impermeable flexible material to which a urine sensing pad is detachably mounted. An electrical circuit carried by the belt, which may include a transmitter for sending a encoded signal to a receiver at a remote location, is responsive to the detection of urine by the urine sensing pad to provide an indication of this condition. The electrical circuitry is shielded from corrosive urine by the belt assembly. In one form, the urine sensing pad is detachably mounted to the belt by a combination of hook and eye fabric and snap fittings. Also, the urine sensing pad may be enclosed by a sheath of soft liquid absorbent material. In another form, the urine sensing pad is contained within a paper envelope.

Abstract: Locking structure for securing a four-bar linkage or the like on an implement in a raised position to remove an earthworking tool or row unit from ground engagement. An overcenter spring arrangement selectively biases a strap pivotally connected to one arm of the linkage toward or away from a member located on the opposite arm. When the strap is biased toward the member, raising the tool or row unit causes the strap to engage the member to prevent rocking of the linkage and thereby secure the device out of ground contact. Reversing the spring arrangement and raising the device causes the strap to move out of locking engagement with the member for normal operation. An elongated device includes pins for aiding the operator in both moving the over-center spring arrangement between positions and raising the tool or row unit.

Abstract: A mat for surgical specimens and the like. The mat is comprised of an upper and lower layer. The upper layer is comprised of flexible absorbent material upon which a grid is imprinted in order that specimens may be photographed with spatial and size orientation. The absorbent nature of the upper layer provides for absorption of blood or other body fluids. The bottom layer is comprised of a flexible non-porous material to prevent staining of a work surface supporting the mat. The two layers are sealed together to prevent drainage along the interface of the layers.

Abstract: A toy-arm imitating a portable fire-arm, operating by compressed air for the pneumatic launch of a light bullet, made up of two reciprocally movable carriers, one first of which comprises a cylinder lined up and communicating with the barrel and a reaction bearing for a spring acting on a piston to urge it into such a direction as to compress the air in the cylinder for the pneumatic launch of the bullet; the second carrier comprises an elastic tooth which hooks up the piston to drag it along while loading the spring, and the first carrier has a profile capable of gradually acting on the elastic tooth at the end of the relative stroke between the two carriers, until causing the release of the piston and its trip thanks to the loaded spring.

Abstract: An emergency transport neck immobilizing brace incorporates a frame structure adapted for mounting on the shoulders of a patient suspected of having a neck injury and securable to the body of the patient by straps.
