Abstract: A fuse element for an electrical cartridge fuse comprises a fusible wire secured to opposite end zones of an insulating strip by metallic layers sprayed onto the end zones. The insulating strip has a slot therein between the end zones to prevent the fusible, central section of the wire from contacting the strip. The fuse element is disposed in an insulating barrel and the layers are soldered to end caps of the barrel to connect the fusible wire thereto. Fuse elements of this construction are produced by disposing a fusible wire along a continuous strip of insulating material formed at equally spaced intervals with slots and spraying the metallic layers onto the strip between the slots so as to adhere the fusible wire to the strip. Thereafter, the strip is severed at the zones between the slots so as to produce individual fuse elements. This method of manufacture facilitates the production of cartridge fuses utilizing small diameter fusible wires.

Abstract: The bottom portion of a drain or sewer, partially filled with flowing liq, is cleaned by placing a cleaning member therein. The cleaning member rolls freely along the bottom portion of the sewer at a lower speed than the flowing liquid. The interior of the cleaning member contains a braking material and throttle structure which tend to reduce the rolling speed of the cleaning member. The cleaning member has an asymmetrical outer surface formed by a plurality of non-intersecting ribs which are asymmetrical with respect to all meridian planes defined by a plurality of rolling meridians along which the cleaning member can roll. This asymmetrical outer surface structure induces a corresponding asymmetric liquid flow around the cleaning member and downstream thereof; thereby laterally deflecting the downstream flow and suspended contaminants out of the rolling path of the cleaning member.

Abstract: A building block system comprised of three basic blocks. A first block has the shape of a rectangular prism and is of a more or less standard cinder block design. A second block has a main body portion that is similar in size and shape to the first block. The second block also includes a pair of spaced apart, mirror image protrusions that extend outwardly from one of the vertical faces of the main body portion. The protrusions define a vertical channel that is laterally centered on the second block. A third block also has a main body portion similar in size and shape to the first block. The third block also includes a pair of spaced apart protrusions extending from one of the vertical faces of its main body portion. The protrusions on the third block are laterally offset to one end of the block. The blocks can be stacked together end-to-end and in courses to form rigid, load-bearing structures.

Abstract: To track an object such as a space probe or a satellite emitting an electromagnetic radio signal, the signal received at a ground antenna is passed through a circular waveguide section propagating modes TE.sub.11 and TE.sub.21. Polarized signal components of the higher TE.sub.21 mode are extracted from the waveguide through two pairs of lateral slots and their differences are multiplied by an r-f reference signal of the same frequency obtained from a preamplifier coupled to an output port to which the signal of mode TE.sub.11 is transmitted by way of a rotatable polarization changer. Corrective signals resulting from these multiplications are proportional to spatial coordinates of the tracked object in a predetermined Cartesian system, one of whose axes coincides with that of the waveguide section, and serve to keep the antenna trained upon the object.

Abstract: The present invention provides a system for overriding the prior art automatic levelling system for vehicles riding on fluid suspensions such as air bags. Such systems utilize a link extending between the vehicle axle and a regulating valve whereby the valve is responsive to vertical axle movement to alter the pressurization of the air bags and hence the clearance height between the vehicle bed and the axle. In the present invention the link is replaced by a cylinder and piston actuator which is connected to a master control via a conduit. An incompressible fluid fills the actuator chamber, the conduit and the master control chamber. The master control chamber may be varied in volume to produce a corresponding change, via the fluid, in the actuator chamber resulting in relative movement between the actuator cylinder and piston and hence operation of the regulating valve.

Abstract: The ignition assembly of a non-electric delay detonator which is adapted for field-assembly with a low-energy detonating cord has an expansion shell provided with a cavity into which the cord is inserted at the time of use. The pressure pulse resulting from the detonation of the cord causes the shell to expand and an ignition charge to be actuated as a result of sudden compression between the expansion shell and a rigid ignition capsule. The burning ignition charge causes the ignition of a delay charge, which in turn ignites a priming charge, causing the base charge to detonate. The presence of ignition charge in an annular spacing between the expansion shell and ignition capsule walls, as well as between the shell and capsule ends, and the proper positioning of a cord-gripping means, preferably in the shell cavity, assure actuation of the ignition charge whether or not the cord is shoved to the bottom of the shell.
