Abstract: ABSTRACT OF THE DISCLOSURE         For the purpose of detecting phase changes (sin .delta.) in an alternating-voltage mains, an apparatus is provided in which in each mains-phase a weakly attenuated oscillating circuit follows the mains-phase position after a considerable delay.  Further, a multiplier is provided in each mains phase, to which are passed the output voltage from the relevant oscillating circuit and a voltage perpendicular to this voltage in the steady state.  The phase-changes (sin .delta.) arising are taken off by passing the output voltages from the multipliers to an adding amplifier.

Abstract: ABSTRACT OF THE DISCLOSURE   Disclosed is a vacuum switch comprising a three-phase contact set, each contact pair of which comprises a stationary contact and a mobile contact, each pair being accommodated in a common vacuum chamber.  The three mobile contacts are connected via a common flexible mounting, comprising a bellows and a base member, to a first wall of the vacuum chamber and the three sta-tionary contacts are secured to a further wall of the vacuum chamber.  Pre-ferably, each mobile contact is secured to the base member via an electrical insulator and each stationary contact is connected to the further wall of the housing by an electrical insulator whereby the bellows and the housing are electrically insulated from the contacts.  The chamber may be divided into three discharge chambers containing respective contact pairs by metal dividing walls disposed in the form of a star.  The simple design allows for low-cost manufacture and the service life of the parts involved corresponds to that of the actuating mechanism.

Abstract: ABSTRACT OF DISCLOSURE         This invention is concerned with a removable filter to prevent the buildup of creosote in chimneys.  Such buildups create a fire hazard which can be obviated by the apparatus of the invention.  A hollow enclosure means that is adapted to connect between the chimney and the fire source has within it a support for mounting a filter.  The filter is made of a special metal, is knitted with small openings therein permitting the flow of smoke, but at the same time reducing the particles into a minute white ash.  The filter acts as a continuous burn reactor.  A door is provided whereby the filter can be easily removed from the hollow enclosure and cleaned so that it can be used for an indefinite period without replacement.

Abstract: REACTION VESSEL ABSTRACT OF THE DISCLOSURE The present invention relates to a reaction vessel adapted to withstand pressures and temperatures of the magnitude associ-ated with the manufacture of diamond products and boron nitride (BN) and similar hard materials.  The reaction vessel has an outer chamber or shell formed from steel and an inner reaction chamber. Known vessels of this type must be provided with a thick layer of insulating material between the reaction chamber and the outer steel shell to protect the outer shell from the heat of the diamond-forming process carried on in the reaction chamber.  The quantity of insulating material required within the vessel for adequate protection of the outer shell is relatively large as compared to the area of the outer shell.  Accordingly, the amount of available space remaining within the vessel for the diamond-forming reaction is limited, thus limiting the size of the dia-monds formed.  The present invention provides a reaction vessel with a cooling system which eliminates the need for the large quantity of insulating material in the known vessels.  As such, the reaction vessel provides a significantly larger reaction chamber for the diamond-forming process, and the resultant dia-monds are up to a thousand times larger than those formed from known reaction vessels.  In one embodiment of the invention, the cooling system includes a plurality of truncated steel pyramids arranged to form flow passages or channels for a cooling fluid adjacent to the inner wall of the vessel's outer steel shell to absorb and disperse heat before it penetrates the outer steel shell.

Abstract: ABSTRACT OF THE DISCLOSURE       A thrust producing shoe sole and heel having fluid-proof cavities located in the heel portion and in the sole portion which underlies the metatarsal ball area of a foot for which the sole and heel is sized, the cavi-ties being connected by restricted passageways. The material underlying the cavities at the bottom of the sole and heel is resilient and wear-resistant.  Fluid is contained within the cavities and passageways in such pressure and amount as to cause bulges below the normal bottoms of the sole and heel, whereby at rest a foot on the sole and heel is cushioned comfortably on the fluid in the bulges, and in walking and running, fluid under bulge producing pressure alternates through the passage-ways between the cavities, producing shock absorption and an alternate lifting effect by the sole and heel bulges which provides forward thrust both in the heel portion and in the metatarsal ball area that facilitates walking and running.  The shape and disposition of the heel bulges and of the metatarsal ball area bulges are such that the sole and heel of the invention exhibits superior lateral stability.

Abstract: ABSTRACT OF THE DISCLOSURE           An emergency locking retractor for a vehicle occupant restraint belt comprises a locking mechanism having an inner disc that is received on the reel shaft for axial movement toward and away from a side frame member in which the reel is supported, an inertia spring that normally holds the inner disc in an outward position in which the mechanism is unlocked, and an outer disc fixed on the shaft against axial outward movement away from the frame.  One of the two discs is rotatable relative to the shaft, while the other rotates with the shaft, and coacting cam elements on the inner and outer discs shift the inner disc toward the frame when the reel is pulled out abruptly and engage coacting locking ratchet teeth on the inner disc and the frame to stop the inner disc from rotating.  The reel shaft is locked to the inner disc by a flange on the shaft having lugs that fit into locking slots in the inner disc.  A third set of ratchet teeth on the circumference of the rotatable disc are engageable by the pawl of an inertia-responsive device and initiate the same locking operations as the abrupt pulling out of the belt produces.

Abstract: ABSTRACT        A low liquid level sensor in a hot water heating system permitting testing operability thereof in situ without draining down the system.  The sensor is located in a cavity that has an opening in the bottom thereof in fluid communication with the liquid in the vessel during normal operation of the system.  The end of the opening is at a lower elevation than the sensor and liquid from the vessel is in the cavity during normal operation of the system.  When the liquid drops to a predetermined low level the sensor activates the safety cut-off.          Valved passage means are provided exteriorly of the vessel so that a gas can be injected into the cavity to pressurize the same and drive the liquid in the cavity through the opening into the vessel simulating a low water level condition.  At the simulated low water level condition operability of the sensor can be determined.  Means are provided to release the gas from the cavity.  The sensor is mounted by an insulator that projects into the cavity and the gas release means is spaced from the end of the cavity so that an air pocket is maintained reducing the tendency of conductive deposits to build up on the insulator.  A fail safe circuit is provided avoiding mal-functioning of the cut-off safety control should there be a large build up of conductive deposits on the insulator.

Abstract: ABSTRACT OF THE DISCLOSURE    A digital information storage and read-out system in which digital elevation and cultural terrain data is read from a magnetic tape in compressed form into an intermediate memory which operates as a speed buffer memory.  The data in the intermediate memory is read out to a reconstruction processor in which the compressed data is reconstructed and applied to a scene memory.  A navigation computer determines the instan-taneous position of a vehicle with respect to the terrain and controls the reading of data into the scene memory in blocks with the vehicle position occupying a center of scene location.          In order to provide a heading up display of the terrain, the data in the scene memory is read out at an angle to its north-up storage orientation and interlaced scanning of pixel data in the scene memory improves resolution and enhances line display.  The data read out of the scene memory controls the generation of video control signals to effect a display of the elevation and cultural data as a moving map related to the vehicle position.
