An atomiser for dispensing perfume or other liquid comprises a pump in the form of a piston slidable in a cylinder, liquid being discharged only when a predetermined pressure exists within the cylinder. Ridges on the inner surface of the cylinder cause deformation of the piston at the end of its compressive stroke; such deformation causes air-escape passages to be formed between the piston and cylinder to facilitate priming of the pump.

The invention relates to an improved means and process for welding wires and, more particularly, for welding lead wires to the ends of the magnet wire in small wire coils. The invention also embraces an improved welding torch using a small-orificed burner tip and providing a sheath of shielding inert gas around the welding flame. Improved fixture means is likewise provided for tensioning and holding the wires in intimate contact while welding or fusing. The fixturing includes a means holding one...

Apparatus for feeding especially tobacco comprises a silo which has a floor formed by a conveyor for carrying a mass of material in the silo towards a discharge end of the silo, and includes an infeed device which is arranged to move continuously along the conveyor in a controlled oscillatory motion having a mean position which, while the conveyor is stationary, moves from one end of the silo towards the other.

A pair of tranversely spaced arms are connected by several hanger members from which objects to be dried may be hung. These hanger members may be of two telescopable sections each. Free end portions of the arms each carry a suspending unit composed of an abutment bracket of L shape which is rigid with the arm and a hook which has an extension portion of rod shape guided in a bore of the arm so that the hook can be slit longitudinally as well as turned with reference to the arm. Arresting devices...

As compositions of matter non-agglomerating microspheres of oxides in the 5 to 500 micron size range. The particles have a uniform crystallite structure with a grain size of 1 micron or less, and a sigma value derived from the equation Sigma = D/D.sub.s of about 1 to 1.3.

A unit which is useful in a measuring device such as a vibration rod transducer. The unit comprises supported diamond layers having an unsupported bridging diamond strip which is integrally formed with the supported diamond layers. The supported diamond layers may form part of a closed configuration such as a circle, square, rectangle or triangle. The diamond is preferably CVD diamond.

An enzymatic process for extracting a nucleoside, such as thymidine, from a biomass without substantial thymine production.

An agricultural vehicle has a wheeled frame and a load-receiving chamber enclosed by a framework. A loading mechanism comprising upper and lower gripper members actuated by hydraulic pistons of a control system is mounted at one end of the chamber near an open side. The gripper members can include curved tines, with or without blades, that can be moved to pick up and load crop material in the chamber. A draw bar is pivoted to the frame laterally thereof. The draw bar can be a hydraulically actua...

Fiberballs are prepared from mechanically-crimped fibers having both a primary crimp and a secondary crimp with specific configurations, especially amplitudes and frequencies. The fiberballs may contain a proportion of other fibers, particularly binder fibers.

A method for varying the color of an image including lines and background. Where the image includes the colors black and white and a plurality of gray pixels, where gray refers to the presence of pixel values between the maximum and minimum pixel values, inclusive, the image is first converted to a color space, such as for example, r, g, b (red-green-blue). Pixel values are thresholded for differentiation between lines and background. When pixels have a value indicating that the pixel is backgro...
