Abstract: ABSTRACT      An elevator for farm produce  or other articles includes a pair of continuous entrainments each having a series of spaced members, such as rods or rollers, supported by continuous bands.  One entrain-ment is mounted within the other and the inner entrainment is slack over an ascending section so that it normally sags towards a corresponding section of the outer entrainments.  When the entrainments are driven, material is picked up by the outer entrain-ment as it passes around inside a hopper.  This travels up the ascending section whereby the slack section of the inner entrainment moves away from the correspond-ing section of the outer entrainment so that the material is elevated as a rising column.  The inner entrainment takes up a natural spacing from the outer entrainment over the elevating sections. The lower end of the inner entrainment may form a converging inlet to assist initial elevation and its upper end may form a diverging outlet to assist in releasing   the material at an outlet.  The lower end of the inner entrainment may include an idler which is mounted on a radius arm or which is supported at each side in a slot or groove.  Conveyors are also described for moving material from a heap into the inlet or hopper of the elevator and for moving material away from the outlet of the elevator.

Abstract: SYNTHESIS OF FURYL INTERMEDIATES, AND CARDENOLIDES AND THEIR ISOMERS PREPARED THEREFROM     ABSTRACT     The invention relates to furyl intermediates and the preparation thereof, said intermediates being particularly useful in the preparation of synthetic cardenolides and their isomers.  The process provides for the reaction of an unsaturated steroidal 17 ketone with a .beta.-furyl compound to produce an allylic alcohol which is subjected to acetylation and allylic rearrangement.  The resulting material is then hydrogenated to produce the furyl intermediate.   Cardenolides are formed therefrom by oxidation of the furyl intermediates.

Abstract: LOCK DEVICE                 ABSTRACT OF THE DISCLOSURE           A lock arrangement is provided which may be actuated by two different keys.  A master key may be used to lock and unlock the device.  A subordinate key may be used to lock the device only.  The lock is of the pin-tumbler type in which the lock's rotatable core plug includes a shallow, longitudinal step groove cut into the top of the core plug.  The subordinate key is identical to the master key except that one or more of the subordinate key's bittings is cut deeper than the corresponding groove or grooves on the master key, the additional depth corresponding to the depth of the step.  When the master key is inserted in the keyway in the core plug, the pin tumblers are raised in the normal fashion so that the tops of the pins are even with the shear line between the core plug and the cylinder.  The core plug may then be rotated in either direction.  When the subordinate key is inserted in the core plug keyway, one or more of the tumbler pins is raised so that the top of the pins is located at a point below the shear line, but at or slightly above the level of the bottom of the step groove.  In this manner the core plug may only be turned in one direction so as to be able to lock, but not unlock, the device.

Abstract: HYDRAULIC VALVE DETENT MECHANISM                 Abstract Of The Invention A hydraulic pilot valve having an improved detent mechanism.  The pilot valve includes a pair of lever operated plunger members which operate sliding valve members to control the opening and closing of a pair of work ports.  Biasing members urge the plunger members to an extended position so as to maintain con-tact with the lever, and a pair of detent mechanisms act to hold the respective plunger members in the extended position.  Movement of the lever to depress either of the plunger members and thus operate the respective valve members to open either of the work ports allows the respective biasing member to move the other plunger member to its extended position where it is held in place by its respective detent mechanism, thus holding the lever in its cocked position.

Abstract: A B S T R A C T Disclosed is a gas-discharge overvoltage arrester comprising two opposing main electrodes and a central electrode surrounding the discharge-gap annularly and coaxially, the said central electrode being connected to the main electrodes by an annular insulating housing, the inside of which carries at least one ignition-strip of electrically conducting material extending over a part of the length of the tube.  This arrester is intended to display high con-sistency of its electrical data during and after surge-current-, alternating-current-, and long-life-loading.  To this end, according to the invention, the main electrodes constituting a discharge gap are stepped inwardly in the form of double-cylinders and have resilient transitions at the ends of the insulating housing; the central electrode, forming a main discharge-yap with each of the two main electrodes, is in the form of a hollow cylinder with a divergent conical profile; and all of the electrodes are provided, in overlap areas, with an electrode-activating substance.  The overvoltage arrester according to the invention is used as a dual-path arrester, for example in protecting communica-tion lines opening jointly into high-rise buildings.

Title: Fabric washing process and detergent composition for  use therein
Inventor: MORRIS RONALD M
IPC: C11D17/00
Filed: 1982-01-13
Granted: 1985-01-15
Abstract: A B S T R A C T:       A process for washing fabrics includes contacting the fabrics with a liquor containing an orthophosphate material and, at least one minute thereafter, contacting the fabrics with a liquor containing a pyrophosphate material free of polymer phosphate.   Each liquor contains a detergent active material and has a pH between about 8 and about 12. The delayed contact with the pyrophosphate reduces the level of deposition on the fabrics and the use of a combination of orthophophate and pyrophosphate enables compositions for use in the process to contain lower than conventional total levels of phosphorus.   The pyrophosphate containing liquor may be separate from the orthophosphate containing liquor, or it may be the same liquor to which the pyrophosphate is added with a suitable delay.   This delay may be achieved by the separate addition of the pyrophosphate material, by the use of a two compartment sachet, by coating, encapsulation or co-granulating the pyrophosphate, or by selecting a particle size for the pyrophosphate which will sufficiently reduce its rate of dissolution.
