Title: Automatic lavatory seat lifter
Inventor: ERDIGUER SHMUEL S
IPC: A47K17/02
Filed: 1990-08-06
Abstract: A B S T R A C T      It is  "An Automatyic Lavatory Seat Lifter"  by  a pressed springy mechanism, that is easily composed to the lavatory seat.     In this mechanism there is a possibil-ty to regulate the pressure of the  spring's  flexibility by  a special  screw-pin.     Due to this  mechanism  the lavatory seat will be lifted automatically and controlled. Until this invention is in use, there is a possibilty  to lift the seat cover without lifting the seat.      It has happened quite often, that when we were ready to make our sitting needs, we found  a filthy and splashed seat with urine drops. Not only that it's certainly unpleasant and unsanitary,  but in certain situations  it can  cause different kinds  of infectious sicknesses . especially  in our time when the terrible  Aids Disease  is widespread .   ( Like by an infected technician, that visited our house and used our lavatory, and so on ... ) But by discovering this invention, the lavatory seat will never be found filthy with urination.     The  seat will always be lifted automatically,except when we are sitting on it, or when it's covered, which  of  course  makes  it unusable.

Abstract: ABSTRACT OF THE DISCLOSURE:          A  tamper-proof bracelet  is  disclosed,  which comprises an elongated band having at least one opening at one end, and a fastener at the other end.  This fastener is in the shape of a housing having circumscribing walls, two of which are transverse to the band, a top wall and a bottom wall.  At least one of the transverse walls is formed, close to the bottom wall,  with a through aperture size to allow snug insertion of the one end of the band into the housing. Above the aperture and solid with the transverse wall is a locking tongue extending lengthwisely in the housing and gradualy tapering down into a thin edge,  the tongue being resilient at least in the area of the thin edge and having a length sufficient to engage the opening in the one end of the band when the same is pushed into the housing through the aperture.  A ramp projects up from the housing bottom wall to force upwardly the one end of the band when the same is inserted in the housing and to keep this band in fully engaged position after insertion, whereby any attempt at pulling the one end of the band out of the housing while lifting the tongue with the blade inserted into the aperture in order to tamper the bracelet,  is rendered much more difficult.

Title: Pivot joint for loader linkages and the like
Inventor: REINSMA HAROLD L
IPC: E02F9/00
Filed: 1990-01-16
Abstract: A maintenance-free pivot joint is disclosed for mounting a first member of a loader linkage to a second member thereof.  The first member is provided with a clevis having a pair of brackets.  The pivot joint includes a pivot pin which is pivotally mounted within the second loader linkage member.  A first end collar is fixedly secured to one end of the pivot pin of the joint and is slidably mounted to a first one of the pair of brackets.  Conversely, a second end collar is slidably mounted on the other end of the pin and fixedly secured to a second of the brackets, but at a preselectable axial position relative to the second member.  The positioning of the second end collar at the preselected position allows the joint to accommodate lateral misalignment between the first and second members of the linkage, while maintaining a closely spaced lateral relationship therebetween to eliminate end play and facilitate good sealability.

Abstract: A vehicle door lock device has a synthetic resin made body and a back plate attached on the rear side of the body. A lock lever is journalled between the back plate and the body in order to change-over the lock device between its locked condition and unlocked condition.  A plastic made actuator box containing a power source for powerfully changing-over the lock lever is placed below the body.  A switch box is formed at a rear side of the box and a switch body is contained in the switch box.  A rotation shaft of the switch body protrudes rearward through the switch box and a switch arm is secured to the protruded portion of the rotation shaft.  At the overlap position of the connecting lever and the lock lever, the connecting lever is installed rotatably, one end of the lever being connected to the switch arm and another end of it being connected to the key cylinder of a door or the lock lever.  The switch body is electrically connected to the lock devices of other doors, functions co-operatively motion of the key cylinder or lock lever, and sends out control signal for changing-over the lock devices of the other doors between their locked condition and unlocked condition.  The switch box is installed at a position where it is not overlapped with the lock lever.  The switch box has a circumferential wall protruded integrally from the actuator box and a lid formed separately from the actuator box, and the bottom plate of the actuator box is used simultaneously as an outer wall of the actuator box.  The lid of the actuator box is even with the back plate or higher than the back plate outward.

Abstract: A vehicle having a fluid-powered rotary dipper stick assembly including a boom attachment head and a bucket attachment head with a body extending therebetween. An axle extends from the boom attachment head into the body and is in sliding engagement with an inward wall of the body to provide lateral support thereto. The axle extends to a midportion of the body. The body is rotatable relative to the axle, and is rigidly connected to the bucket attachment head for rotation together as a unit. A hydraulic motor is operable to produce rotational movement of the body relative to the non-rotating axle. Rotational movement of the body produces rotation of a bucket or other work implement attached thereto about the body longitudinal axis independent of the boom attachment head. The assembly uses a single thrust bearing positioned between the body and the boom attachment head to carry thrust loads in both directions. In one embodiment, fluid passageways in the non-rotating axle and a rotary fluid joint conduct hydraulic fluid between the non-rotating and rotating components.
