Granted: 1991-08-13
Abstract: ABSTRACT COMMUNICATIONS SYSTEMS     A communications network comprises a plurality of stations which can communicate via a ring. Information is transmitted from one station to another in message blocks which circulate around the ring.  The message blocks include control bits and a protocol is employed which ensures that no one station can monopolise the available message blocks.  At any of the stations, an emptying block is utilised by that station as a reallocation trial slot and places its own address therein for passage round the ring.  On its return a system reset is instigated to allow all stations to be reallocated blocks.

Granted: 1991-01-29
Abstract: ULTRASONIC APPARATUS FOR DETERMINING THE AMOUNT     OF LIQUID IN A CONTAINER OF KNOWN VOLUME     Abstract of the Disclosure An ultrasonic apparatus for determining the amount of liquid in a container of known volume include at least a pair of ultrasonic transducers which are mounted a known distance apart relative to the liquid surface so that the ultrasonic energy reflected from the liquid surface traverses the following paths: 1)  from first of the transducers vertically to the liquid surface, and 2)  from the first transducer to the liquid surface and then to the second transducer.  A circuit measures the time of travel T corresponding to path 1 above, and T1 corresponding to one-half the travel time of path 2) above.  The height H of liquid above the transducers is determined by solving the equation:       where S is the known distance between transducers, T is the travel time of ultrasonic energy directly or vertically to the liquid surface and T' one-half the travel time between the two transducer reflected off the liquid surface.

Title: Pallet loading apparatus
Inventor: POSTIGO JOSEPH
IPC: B65G57/30
Filed: 1988-01-04
Granted: 1992-03-31
Abstract: ABSTRACT OF THE DISCLOSURE:     An apparatus for placing a load of stacked articles on a pallet comprises a conveyor having a series of spaced rollers and a bridge structure spanning the conveyor.  Two load lifting structures hang verti-cally from the bridge structure, one on each side of the roller conveyor, and are displaceable toward and away from one another over the conveyor.  Each lifting structure has a lifting frame formed of a vertical ram wall, of a tine carrier at the lower end of the ram wall, the tines of the carrier having tines disposed to be inserted in and withdrawn from spaces between the rollers of the conveyor, and of an operating base supporting the tine carrier during its displacement and being secured to the lower end of the ram wall.  The pallets are fed from a pallet unstacker delivering one pallet at a time on a pallet conveyor extending at right angle from the roller conveyor.  The pallet conveyor has a pallet delivery portion in the form of a chain conveyor of which endless chain portions travel between rollers of the roller conveyor with their upper strands projecting slightly above the conveyor rollers.  The pallets are fed onto the roller conveyor when the ram walls and tines of the load lifting frames are lifted above the roller conveyor a distance sufficient to allow insertion of the pallet. The load between the lifting frames is then lowered onto the pallet; the tines removed from beneath the load while the ram walls are still against the load and thereafter the ram walls are moved away laterally from the load.

Title: Subscriber unit for a trunked voice/data communication system
Inventor: ABLAY SEWIM F
IPC: H04W84/08
Filed: 1988-01-27
Granted: 1990-10-30
Abstract: SUBSCRIBER UNIT FOR A TRUNKED VOICE/DATA COMMUNICATION SYSTEM          Abstract A trunked voice/data subscriber (114) is provided that operates in either a voice mode, or one of three data modes.  In a first data mode (406), the voice/data subscriber monitors the voice control channel to enable rapid participation in a voice call.  In a second data mode (408), the subscriber monitors an assigned data channel until either commanded to change modes or until there has been no data activity for a predetermined time interval.  Lastly, the subscriber may operate to remain in the last mode used so that, over time, the subscriber resides primarily in the mode predominately used. According to the invention, the voice/data subscriber must request a channel for each voice transmission.  However, a data channel request need only be transmitted if no data channels are currently reallocated.  If a data channel has been allocated, the subscriber may transmit at any time without first requesting access.

Inventor: TABOR RICKY L
IPC: C08F291/00
Filed: 1988-02-08
Granted: 1992-04-21
Abstract: ABSTRACT     A polymer grafting process in which a Diels Alder adduct is mixed with a polyolefin or vinyl polymer substrate and thermally decomposed to form an ethylenically unsaturated monomer which grafts onto the polymer substrate.  The monomer conforms generally to the formula R1R2C=CHR3 in which R1 is hydrogen, methyl or ethyl, R2 is hydrogen, methyl, ethyl or vinyl and R3 is hydroxyl, carboxyl, cyanc, formyl, acetyl or propanoyl.  The Diels Alder adduct substantially decomposes at a temperature of 120 to 300°C, but does not substantially decompose below about 120°C.  The polymer substrate is preferably high-density polyethylene, low density polyethylene, linear low density polyethylene, ethylene-propylene rubber, propylene, polystyrene or styrene-butadiene block copolymers. The grafting is induced by, for example, heat, catalyst and/or high shear conditions. Optionally, the polymer mixture is devolatilized to 32,836-F     remove any unreacted Diels Alder adduct and decomposition products thereof.     32,836-F

Abstract: CHEMICAL PREVENTION OR REVERSAL OF CATARACT      BY PHASE SEPARATION INHIBITORS                    ABSTRACT OF THE INVENTION    The present invention relates to a method and reagents for decreasing the phase separation temperature and inhibiting the formation of high molecular weight aggregates in eye lenses to thereby prevent or reverse cataract formation.  These reagents meet the following criteria:  they are able to diffuse from an aqueous solution into the lens and exert an effect over a reasonable period of time; they are not toxic to the lens or surrounding tissue when delivered systemically or topically to the eye; and they do not substantially change the eye color or viscoelastic properties of the lens in a manner detrimental to visual acuity.  In the preferred form, the reagents are applied locally (topically) or orally to minimize the effective dose and side effects.

Abstract: PLATFORM, HANDLE AND SHIELD FOR SAFETY RAZOR     ABSTRACT OF THE DISCLOSURE    A safety razor having a handle carrying a head (12) having two projecting tongues (60, 62), a platform (20) having a pair of undercut recesses (52) for receiving the tongues and a shield for overlying the razor blade head.  The platform includes along its underside a retaining edge opposite the undercuts, a pair of centering ribs (88) spaced one from the other and with tapered edges for engaging the end edges of the handle head, and a pair of crush ribs (92) adjacent the undercuts to bias the head and platform away from one another in final securement. To assemble the safety razor, the handle head tongues are inserted into the undercuts and the handle is pivoted to seat the back edge of its head beneath the underside of the platform edge.  The pivoting action causes the handle end edges to bear against the tapered centering ribs centering the handle relative to the platform and the crush ribs to engage the head to afford a tight fit.  The shield is generally channel-shaped and has angled end edges (86) and lugs at each of the opposite corners for engaging in chamfers formed along the underside of the platform to facilitate centering of the shield on the platform.

Abstract: ABSTRACT          PROCESS AND APPARATUS FOR REMOVING FLESH FROM COOKED          BAKED POTATOS     Apparatus is described for removing flesh from a cooked baked potato half supported in a pocket on a indexed conveyor. The apparatus comprises a plunger carrying a convex-shaped dicer head which is automatically reciprocated by a predetermined stroke in synchronism with the passage of a potato thereunder. The dicer head comprises a plurality of apertures or channels through or into which potato flesh passes as the dicer head is depressed into the potato half. The flesh is either immediately transferred to a conveyor or passes to a conveyor after accumulating above the dicer head. The potato is held down as the plunger is withdrawn by a potato keeper which keeper is carried on the plunger mounted to slide with respect to the dicer head and resiliently biassed to stay in position on the potato as the dicer head is withdrawn. The withdrawal of the dicer head may be assisted by gas jets activated in synchronism with the withdrawal of the dicer head.
