Wear parts or cutting tools, in which the part being exposed to wear is essentially an extremely difficultly grindable material (e.g., hard material), but in which the manufacture of the wear part or cutting tool requires considerable grinding operations can, according to the invention, be made better and cheaper forming the wear part or cutting tool of a compound material which is a wear-resistan...

Method of making collagen gel suitable for use in the manufacture of thin collagen film articles having superior mechanical properties. The method includes the steps of providing clean animal tendon at room temperature containing at least 30% collagen essentially free of ligamentous tissue. The tendon is comminuted in the presence of about 65% water by weight to form a collagen slurry. The slurry ...

The display stand has support shaft (10) which is inclined at approx. 15 deg. to the vertical. Card supports are attached to the shaft and can rotate around it, but with restricted movement. A number of the card supports are located at different heights on the shaft. - The supports have individual card holders which are limitedly pivotable in their connection with the supports. Therefore all holde...

Spur gearing including an outer gear rim firmly attached to the roller to be driven. A first self-aligning bearing disposed within the outer gear rim mounts the gear rim to a firm support. A pinion outside of the outer gear rim meshes with the outer gear rim. A journal in the pinion connects it to a support bracket. A second self-aligning bearing joins the pinion to the journal. A pinion driving c...

The compressor has a cylinder block (14) with a piston (23) and cylinder (20) at the lower end. Above the cylinder block is mounted the motor stator (44). A bearing hub (26) is centrally mounted on the cylinder block, and provides a single radial bearing for the crankshaft (38), which extends upward through the bearing hub and has the rotor (46) mounted on the upper end. The crankshaft is journ...

The invention provides a vapor dispenser for the emission of a vaporizable substance exhibiting an activity in the atmosphere in a trace concentration, such as an insectan sex pheromone used in pest control, at a controlled uniform rate, a large number of which can be distributed in the field with minimum labor, for example, by tying to and hanging on the twigs of tea plants in a tea garden. The i...

Ammonia synthesis gas is made from a raw gas comprising hydrogen, carbon dioxide and medium boiling point gases including nitrogen in excess of the proportion required in ammonia synthesis gas, by a pressure swing adsorption process characterized by feeding to the adsorbent a raw gas in which hydrogen and total medium boiling point gases are present in a volume ratio in the range 1.25 to 2.5, and ...

To regenerate a physical solvent, loaded with sour gases, especially CO2 and H2S, the loaded solvent is treated with a stripping gas and/or is expanded to separate absorbed CO2 and the resultant solvent is subjected to thermal regeneration to desorb H2S. To reduce energy requirements during regeneration, the CO2 desorption is conducted on at least two different temperature levels, the second being...

N,N-Dimethyl-1-[1-(4-chlorophenyl)cyclobutyl]-3-methylbutylamine hydrochloride monohydrate is a non-hygroscopic material which can be used as a pharmaceutical in the treatment of depression.

The terrace plates (10) are supported by prefabricated screen walls (40) located in front of the lower storey roof components. The screen walls themselves are only supported from the main building body (60) at the bottom plane of the lower storeys. Seals are provided in the form of forwardly open, prefabricated trays (30) which with clearance accommodate the rear parts of the terrace plates (10).

The door has a handgrip (34) which is rotatable around a shaft in its longitudinal direction in or adjacent to the door panel (10). Transmission components (48,52) such as gearwheels, couplings or similar, transmit the rotary movement of the handgrip to the press plates (16) via the lock in the door.

The cover (7) or screen of the umbrella or parasol is supported by ribs (5) on a rod (1), and can be raised by sprung components (9). These components exert a traction force on the top of the cover on the ribs from points along their length in the direction towards the rod point.
