Abstract: A source of energy is selectively applied to a liquid stream to reduce the surface tension of the liquid and is applied before the stream would randomly break up into droplets. Both the quantity of energy applied and the time period that the energy is applied are controlled to control the time to droplet breakoff and the time between droplets by selectively reducing the surface tension of segments of the stream. The source of energy can be high intensity light, which is converted by the stream to heat energy, or a source of heat (resistive or inductive) with the resistive heat being applied to the stream by conduction and the inductive heat being converted by the stream to heat energy.

Abstract: A tape reel brake (207) which is mounted in a well (215) in the top of a tape reel hub. The brake (207) is mounted to be compliantly biased away from the base of the well (215). The hub and brake (207) are seated in the tape cartridge (10) such that teeth (239) on the periphery of the brake (207) are biased against the opposite inside surface (14) of the cartridge housing about the periphery of an opening (20) therein. The biasing of the brake (207) against the opposite inside surface (14) both prevents the rotation of the reel (200) and shields out dust when the tape cartridge (10) is removed from a tape drive. To rotate the reel (200), a tape drive clutch enters the opening (20) in the opposite inside surface and depresses the brake (207) into the well (215) to mate with a smaller diameter portion (220) of the hub.

Abstract: A magnetic tape drive 20 includes a tape path 21 having first and second reels 22 and 23 for a tape 1, a transducer head 24 and guides 10a, 10b and 10c for the tape. The guides 10a, 10b and 10c are pivotally mounted on axles 15a, 15b and 15c and the operation of the drive is controlled by a controller 25. Fach of the guides is a constrained pivot compound radius tape post. The post is mounted on an axle which allows it to pivot when the tape changes direction. The pivoting action serves to peel away all tape which has been in stationary contact with the post, thereby reducing startup stiction. Above a certain pivotation angle the post is prevented from further pivotation either by a fixed stop or by torque exerted on the post by the tape which is under tension.

Abstract: A conduction heat transfer connection is made between a heat source and a heat sink which is flexible so as to adapt to variations in distance between the source and sink and which maintains the required force on the heat source to obtain the required heat transfer across the junction therebetween. The connection consists of a heat conductive metallic foil bundle of sufficient thickness to contact sufficient surface area of the heat source to provide the required heat transfer and of sufficient thinness to be flexible enough to absorb the expansion and contraction due to temperature changes as well as the differences in distance between the heat source and sink and of sufficient length to contact at or near the other end thereof the heat sink.
