Abstract: The present invention relates to an isolated receptor-type tyrosine kinase. The receptor-type tyrosine, in its naturally occurring form, is characterized by being reactive to monoclonal antibody III.A4, having an apparent molecular weight of approximately 120-150 kD in its glycosylated form, and having the N-terminal amino acid sequence E L I P Q P.

Abstract: An arrangement for monitoring clock frequency variations on a peripheral bus is provided to improve operations of the peripheral device despite changes in the clock frequency. In one aspect of the arrangement, a processing unit is coupled to a host bus which in turn is coupled to a peripheral bus which is coupled to a peripheral device. A monitoring arrangement is provided which detects a change in the clock frequency of the peripheral bus and determines if the frequency change exceeds a threshold associated with the peripheral device. If the threshold is exceeded, the peripheral device is informed that the clock frequency of the peripheral bus has changed. A peripheral device operating a different operating levels may use the information from the monitoring arrangement to alter the operating level of the peripheral device to conform to the new bus clock frequency.

Abstract: A radiation detector assembly employing an enlarged volume scintillation element and a photomultiplier tube. The scintillation element is surrounded by a reflective material and may be enclosed within a rigid shield for protection against shock and/or humidity. A Sidewall Axial Restraint and Compliance Assembly (SARCA) is positioned radially outside the reflective tape. Radial springs are placed outside the SARCA to provide stiff restraint in the axial and radial directions, The SARCA and springs provide for thermal expansion of the element. A two-stage axial biasing means is positioned at an end of the element, and an optical window may be positioned at the other end. Non-cylindrical portions may be formed along the circumference of the element. These non-cylindrical portions enable a larger element to be placed within the shield. In an alternative embodiment, the element is positioned apart from the photomultiplier tube with no window therebetween.

Abstract: A swing arm assembly (10) for use in converting a motorcycle into a tricycle is described which includes a rear axle assembly (12) and a swing arm (14) having a first end (16) and a second end (18). The first end (16) is adapted for pivotal attachment to a motorcycle chassis. The swing arm (14) is detachably secured to the rear axle assembly (12). A pair of axle engaging members (22) are secured in spaced relation to the rear axle assembly (12). A pair of telescopically extendable/retractable members (24) are provided having a first end (26) and a second end (28). The first end (26) of each telescopic member (24) is telescopically received in one of the axle engaging members (22). The second end (28) of each telescopic member (24) is attached to the second end (18) of the swing arm (14) after a continuous belt for a belt drive is slid loosely into position. The telescopic members (24) are telescopically extendable once the continuous belt is in position to place the belt in proper operating tension.

Abstract: A toy vehicle and helmet combination includes a protective helmet suitable for wearing on a user's head. The helmet, which can be suitable for riding a bicycle, includes a rigid shell with an open bottom, an upper section with one or two slots formed therein, and a lower section extending around the open bottom. Pairs of holes can be formed in the lower section with the holes of each pair located in opposite sides of the lower section and substantially aligned. A toy body section with an upper body member is mounted on top of the shell and has one or two downwardly extending connecting members sized to extend through the slots in the shell. There are also toy wheels and shafts rotatably mounting same to the helmet.

Abstract: A unitized scintillation detector, employing a scintillation element and a photomultiplier tube housed within inner and outer housings for protection against shock, and a scintillation shock assembly. The scintillation element is encased within potting material, which is further enclosed within a rigid shield. A reflective coating or reflective tape may be used to optimize light impulse transmission from the element to the photomultiplier. The element is further protected from shock by an elastomeric boot disposed around the shield and within the housing. In addition, elastomeric material cushions the element on one end and a spring system protects the other end. The spring system is pre-loaded against the shield, not the element. Dual windows interfacing the scintillation element and photomultiplier tube at the other end of the element create an hermetic seal. In another embodiment, a single optical window may be used.

Abstract: The present invention relates to a method of screening for ligands to a receptor-type tyrosine kinase. The receptor-type tyrosine, in its naturally occurring form, is characterized by being reactive to monoclonal antibody III.A4, having an apparent molecular weight of approximately 120-150 kD in its glycosylated form, and having the N-terminal amino acid sequence E L I P Q P.

Abstract: The invention provides the peripheral edge portions of rigid sheet-like panels with locking edges arranged for mating, snap-fit locking engagement by panel connector members, whereby a plurality of panels may be connected together to form building structures such as doll houses, children's play houses, utility sheds and the like.

Abstract: Disclosed herein is a device for connecting corrugated drainage tiles and the like which comprises a sleeve member which fits around the adjacent ends of coaxial drainage tiles. The sleeve member includes first tabs at one end which extend from a first side of the sleeve member and are received within the external, circumferential channels in the drainage tiles. Each of the tabs defines an interior chamber which opens on the second side of the sleeve member. The other end of the sleeve member includes second tabs which are adapted to be received through the openings and within the interior chambers of the tabs on the first end of the sleeve member. The sleeve member includes several, additional tabs which are received within the external, circumferential channels of the drainage tiles. The sleeve member may thereby be positioned about the adjacent drainage tiles and the ends of the sleeve member are secured together by insertion of the second tabs into the respective interior chambers of the first tabs.
