A trailer with a pull-out unit to provide additional space; the unit is hinged and has seals which provide for weather-proofing in both the open and closed positions.

A crane boom radius transmitter employs a boom radius-to-electric signal converter comprising a movable member made in the form of a screen consisting of two sections, which movable member rotates as the boom angle changes. The screen moves between the coupling cores of an inductively coupled detector and sine-wave generator to produce a signal proportional to the boom inclination. Simultaneously, the cores are arranged to rotate relative to the screen as the boom length changes, thereby causing...

A fire venting skylight of the drop-out variety consisting of nested double domes. The outer dome which may be thicker than the inner dome is spaced from the inner dome except at its periphery. The periphery of the outer dome is clamped against the upper surface of the inner dome at a marginal distance from the edge of the inner dome. The outer dome has a diameter which is smaller than the diameter of the skylight well. The inner dome has a diameter which is larger than the inner diameter of the...

An In-Out Transporter arrangement for an enclosed chamber, subjected either to a vacuum or to a positive pressure, comprising in combination a gasket sleeve on and covering an entrance and/or exit of the chamber, a cavitied rotor rotatably disposed in the gasket sleeve so that the cavitied portion of the rotor may be selectively rotated into or out of the chamber. The rotor and the gasket sleeve being arranged in such tight fitting relationship that the integrity of the vacuum or pressurized con...

In a coin pay-out device to which the present invention is applied, the rotary arm of the second change slide is extended to a space between adjacent first change slides and the rear end side of the rotary arm is used as a stopper for disabling the rotation of the rotary arm. Consequently, it is possible to dispose the solenoids of the second change slide and the solenoids of the first change slides side by side. As a result, the disposition space of each solenoid can be reduced both in the tran...

A unitary removable barrier for installation in a cylindrical water line to selectively block the water line to passage of water therethrough. The unitary removable barrier is composed of a single piece rubber body having at least one cylindrical section sized to receive upstream and downstream pipes of the water line. A unitary rubber planar disc molded with the cylindrical section is of a circular circumference and which completely blocks the water line but which is selectively removable from ...

A vehicle including a seat lock-out assembly which discourages the unauthorized use of a seat on the vehicle. The vehicle includes a chassis and at least one seat having a body support fixed relative to the chassis. The seat includes a body support. The seat lock-out assembly has first and second ends fixed to the chassis, and extends over the body support to discourage unauthorized use of the seat. In one embodiment, the seat lock-out assembly includes an elongated member and a shield fixed to ...

A carry-out bit generator determines if a bit pattern from two positive numbers matches one of the patterns for which a carry-out bit would be generated in addition. These patterns include a T.sup.n G pattern and a T.sup.m pattern (with a carry-in). Superscript n represents a number between zero and m-1, superscript m represents the number of registers, T represents a 0/1 or 1/0 pair and G represents a 1/1 pair.

A pedal assembly 10 for use in a vehicle 11 includes a pedal arm 100 that moves in a normal operating range between a rest position and an applied position under a normal operating load. The pedal arm 100 moves in a plane about an axis of rotation. The pedal assembly 10 includes a mechanism 102 for releasing the pedal arm 100 from its support 16 in response to a predetermined force applied to the pedal arm 100.

An image reading-out apparatus provided at least with a document table made of a transparent material that passes an image reading light beam and having a flat surface on which a document can be set and a cover that presses the document set on the document table and prevents the image reading light beam from leakage includes a display/edition unit. The display/edition unit has a display section having a large area for displaying an image that has been read-out via the image reading light beam an...
