Abstract: This invention provides a deformable dispensing tube (1) with an internal device (8). The device is contained within the deformable dispensing tube but is a separate physical entity to the deformable dispensing tube and has the ability to move within the deformable dispensing tube. The object of the device is to aid the dispensing of part or all of the contents (16) of the deformable dispensing tube by the user.

Abstract: The point is adapted to fit onto the forwardly projecting mounting wedge of a tillage shank and has a downwardly and forwardly inclined, elongated crown provided with a transverse, sharpened tip at its lower front end. An underslung transverse wall looped under the crown at the front end of the point defines a rearwardly opening socket that matingly receives the apex of the mounting wedge of the shank, and depending sidewalls on the crown adjacent its opposite lateral edges rearwardly of the underslung wall serve to present a protective trough on the underside of the crown that matingly receives the upper surface of the mounting wedge so as to protectively cover otherwise exposed side portions of the wedge and thus shield such areas from exposure of abrasive soils.

Abstract: An attachment for permitting the focus of a microscope while operating the microscope stage may be provided with means including a fastener engagable with the focusing control of the microscope and providing an extended surface to permit simultaneous and one-handed operation of the microscope focusing control and the microscope stage by an operator.

Abstract: A high power single mode laser is disclosed which includes a Q-switch for switching the laser on in two stages: firstly, to a relatively high loss level just above threshold where it is held to permit a train of relaxation oscillator spikes to be established and then it is switched to a second stage in which the Q-switch is in a lossless state to allow the resonant mode within the laser to build up to maximum power. An optical detector monitors the resonant optical radiation level within the optical resonator and produces an output signal for each of the relaxation spikes. A trigger circuit, responsive to the detected oscillator spikes, triggers the Q-switch so as to switch it to the second or lossless state upon receipt of the second or any other subsequent relaxation oscillator spike, whereby single longitudinal mode operation of the laser is enhanced.

Abstract: A holder for setting a group of tiles on a receiving surface has a base plate provided with permanent magnets dispersed over its surface to hold an array of magnetically attractable tiles. Pusher pins slide through the plate to push tiles therefrom. In an alternate form the plate is made of or incorporates magnetically attractable material for holding tiles having permanent magnets therein.
