Abstract: Low load operating point for a direct-injection controlled auto-ignition four-stroke internal combustion engine is reduced without compromising combustion stability through a split-injection control operative to introduce a first fuel fraction, air and exhaust gases into the combustion chamber during an intake event and a second fuel fraction into the combustion chamber during a compression event.

Abstract: Low load operating point for a controlled auto-ignition four-stroke internal combustion engine is reduced without compromising combustion stability through a valve control operative to establish sub-atmospheric pressure conditions within the combustion chamber into which fuel and exhaust gases are introduced.

Abstract: A hook for a mail bag, the hook including a planar attachment portion for attachment to a mail bag, the attachment portion defining a longitudinal axis; a planar supporting portion extending from the attachment portion in the direction of the longitudinal axis and which is planar with the attachment portion, the supporting portion defining an aperture therethrough; and a retaining portion which extends in the plane of the supporting portion and which partially occludes the aperture of the supporting portion, the retaining portion being resiliently deformable out of the plane of the supporting portion.

Abstract: A children's kit for illuminative decoration of the exterior shell (17) of a pumpkin, without requiring a carving knife. The kit (10) consists of packaging (12), light pegs (60), a pattern sheet (30), a tool (100), and light (25). The light pegs (60) are a light transmissive material that can be colored and have a length at least equal to the pumpkin shell thickness. Each light peg (60) has a first end (66) that is convergent to pierce the exterior shell wall (17) and is operative to collect light, a shaft portion (68) to transmit light to a second end with an enlarged peg head (62). The enlarged peg head (62) protrudes above the shell surface and is operative to disperse light. The pattern (30) locates the light pegs (60) on the pumpkin shell (15), with the tool (100) used to drive the light pegs (60) through the pumpkin shell. The light (25) is placed inside the open interior of the pumpkin (14) to illuminate the light pegs (60).

Abstract: Pharmaceutical compositions comprising a mixture of hyaluronic acid and liposomes. Preferably, the pharmaceutical compositions further include a pharmaceutically active substance such as cyclosporin A encapsulated in the liposomes. A method for preparing a pharmaceutical composition includes producing liposomes from phospholipids, preferably in the presence of a pharmaceutically active substance (most preferably cyclosporin A) to be encapsulated within the liposomes, and mixing the liposomes with hyaluronic acid. Pharmaceutical compositions of this invention are used, for example, to topically administer pharmaceutical agents effective to treat skin disorders by deposition of that agent in the dermis or sub-dermis while minimizing systemic circulation thereof. These compositions are also administered orally, parenterally and intrarectally.

Abstract: A vector network analyzer for performing swept frequency measurements on non-linear RF devices, using either an internal or external signal source. This simplifies and speeds linear and non-linear amplifier and mixer measurements, such as impedance, amplifier gain, and mixer conversion loss, on the one hand, and measurement of harmonics, on the other hand.

Abstract: A load carrying pallet of the type comprising a base provided adjacent each end of each side with a support surface level with the deck of the base and terminating in an upstanding lug, and with an upwardly facing channel subjacent each support surface, for use with detachable walls, each having at the lower end an upper transverse frame member to rest on the support surfaces and having depending leg members with lower transverse members for locating in the channels, is improved--as to ease of application and removal of the walls and as to interchangeability with known pallets--by providing between each support surface and the subjacent channel a catch on an axis parallel to the support surface, the catch having upper and lower outward projections and spring latching means, whereby, in one position of the catch the lower projection extends from the slot and over the channel, in another position of the catch the lower projection is withdrawn into the slot, and in both positions the upper projection extends fro

Abstract: An analyzer for an electrical vehicle control system which includes a self-contained power source to allow excitation and evaluation of individual components in the control system. The analyzer plugs into the control system and includes a plurality of switches for selectively connecting various output terminals of the analyzer to internal logic circuits for monitoring the operation of selected components of the control system on an individual basis.
