Abstract: A cigarette packing machine comprises a series of individual cigarette hoppers (18) carried by an endless band (16), the hoppers receiving cigarettes from an input conveyor (15) in a receiving region and supplying groups of cigarettes to a pocketed bundle conveyor (22) in a delivery region. Each hopper (18) may be vertically movable, with its position controlled so that it occupies an upper position in the receiving region and a lower position in the delivery region. The hoppers may be vibrated during movement by the endless band, so as to promote downward movement of the cigarettes. Preferably each hopper has an associated transfer plunger (46) which is extended to deliver cigarettes in the delivery region, the hopper being lifted when the plunger is in its extended position and lowered when the plunger is in its retracted position.

Abstract: Solid rocket motor propellant formulations are provided which are capable of burning at at least two selected burn rates. The burn rate is controlled by controlling the pressure at which the propellant burns. For example, it is possible to mechanically modify the container, such as a rocket motor casing, in which the propellant is held in order to modify the pressure under which the propellant burns. Alternatively, the propellant may be configured or molded such that the pressure changes at a chosen time due to the process of burning the propellant. The propellant is capable of burning at a relatively constant burn rate at a chosen pressure. Once the pressure changes which chosen limits, the burn rate of the propellant is rapidly modified to another relatively constant burn rate. The solid rocket motor propellant is formulated with the addition of from about 0.5% to about 4.0% TiO.sub.2. The specific operating pressures and burn rates can be selected by modifying the amount of TiO.sub.

Abstract: An interconnect for use in a field emission flat panel display device for providing an electrical interconnect between a bond pad 42 on the anode plate 10 and an electrically conductive region 44 on the emitter plate 12 comprises an electrically conductive protuberance 40 attached to region 44 which extends above the surface of region 44 to such a height that when emitter plate 12 and anode plate 10 are assembled at their intended relative positions and spaced from one another at a prescribed distance, structure 40 is forced into compression against the surface of region 42. In one embodiment, gold wire bonds 52 and 56 are attached to bonding pads 64 and 66 on opposing surfaces of anode plate 10 and emitter plate 12, respectively. Bonds 52 and 56 are compressed against one another when plates 10 and 12 are assembled, causing them to be deformed into generally spheroid shapes, the contact between them providing a reliable, low resistivity interconnect between their respective bond pads 64 and 66.

The getter 52 may be formed on a substantially opaque, electrically insulating material 50 affixed to substrate 42 in the spaces formed between conductors 46, which acts as a barrier to the passage of ambient light into and out of the device. Methods of fabricating the getter stripes 52 on the anode plate 40 are disclosed.
