A system of changing the travelling speed of a working vehicle in which a stepless speed-change means is operated by a pedal. Said system has a cam mechanism by which the pedal may be fixed at the desired position, and a first manual lever for operating this cam mechanism.

A crushing apparatus is fitted with hammers which preserve the hammer spindle. The bores of these hammers have a wall which is made curved away from the hammer spindle towards the two edges, leaving a shorter, straight middle piece. Thus the individual hammer can execute a limited rolling movement on the hammer spindle, without unfavourably influencing the hammer spindle in doing so. Likewise the ...

A method of producing a tension-proof thread connection by splicing includes preparing threads for splicing by contacting ends of the thread with a hot gas before splicing for dissolving the thread ends into open-ended individual fibers, for softening the individual fibers and for making the fibers better suited for splicing; and subsequently splicing the threads by alternatingly tangling, interlo...

Device for the selective crushing of cuttable or choppable material such as foliage, mown grass, paper and the like, and of machinable or choppable material such as relatively thick branches and the like. The device has a motor-driven blade shaft (15) standing upright in the centre in a blade housing (17), to which shaft blades (21, 22, 23, 24, 55, 57) and ejection vanes (25, 29) are connected fix...

A thread (3) paraffining device employing a paraffin element (2) which is resiliently biased against a stop rail (6). The stop rail 6 extends transversely to the thread path direction and is arranged on one half of the end face (20) of the paraffin element (2) remote from the thread contact side. The paraffin element (2) has a diameter of at least 50 mm.

An incontinence device consisting of a rectangular pad of absorbent material incorporating along its upper surface at least one strip of a skeleton polyester foam material, the function of which is to enable urine to flow rapidly to the surface of those regions of the pad not immediately saturated by urine. In a preferred embodiment there are provided three strips of skeleton foam, two peripheral ...

A vehicle control and guidance system in which a desired route for the vehicle is stored in the vehicle in the form of co-ordinates in a ground reference frame. The "vectors" between these junction points are divided by successive reference points into incremental vectors, the reference points being generated ahead of the vehicle at regular intervals. A dead reckoning system predicts the position ...

A driverless guided vehicle movable along a guide path includes a wheel support device for supporting a wheel disposed in rolling engagement with a floor. The wheel support device is resiliently mounted on a body of the guided vehicle for vertical movement relative thereto. A detecting means for detecting the guide path and sensible markings along the guide path is fixedly secured to the wheel sup...

An intrusion alarm system with an automatic exit control and a misset indicator which informs that someone has trespassed by opening a door during the resident's absence. This system comprises a sequential circuit which is enabled by mode selection by the resident at his/her going out and which stores the door's opening and closing signal produced as an output signal of a door open/closed detectio...

A method and apparatus for effecting vital functions notwithstanding the fact that non-vital hardware is employed. A vital processor is implemented using non-vital hardware in the form of a digital computer which may for example be a microprocessor. The vital processor accepts binary input values and, based on a series of logical expressions relating output values to input values, determines the a...
