Patent EP-0219227-A2 (EP)
Inventor: PALMER GARY E
IPC: A47L11/164
Filed: 1986-09-12
Abstract: A driver assembly (24) for the pad (35) of a high speed floor burnishing machine includes a flexible back plate (29) having a peripheral retaining skirt (30) which centers the pad (35) on the driver assembly (24) and also prevents the edges of the pad growing or expanding to a larger circum­ference during high speed rotary burnishing action. The backing plate (29) adds stiffness to the pad (35) when rotating at high speed, and it promotes uniform contact of the pad with the floor at the outer radial extremities of the pad where the velocity is greatest and the polishing is most effective. The pad (35) and driver assembly (24) are surrounded by a shroud (17) which is continuously evacuated by radial air flow generated by the motion of the driver assembly which includes a finned hub (25, 26). The air flow carries debris generated by the burnisher to a collection bag or filter without leaving the machine.

Title: Magazine for automatic artillery pieces
Inventor: LINDBERG SVEN
IPC: F41A9/68
Filed: 1986-06-17
Abstract: @ The disclosure relates to an extremely compact, preferably gun-mounted magazine (2) for fully-automatic artillery pieces. The magazine (2) according to the invention includes a plurality of round compartments (I-VI) which are disposed in parallel side-by-side relationship and each accomodate a plurality of parallel superposed rounds which may successively be fed down towards a discharge position specific to each round compartment. Together, these in turn form a transverse feeding channel (6) along which a special, stepwise operating transverse feed mechanism (6) works. According to the invention, each compartment (I-VI) is provided with a specific round hoist (8) which lifts all rounds in the compartment apart from that round which lies in the discharge position. The round hoist in that filled compartment which lies most distal from the piece, seen in the direction of feed of the transverse feeding channel, must, however, always be in the unsecured state so that this compartment continually supplies fresh rounds to the transverse feeding channel. Special sensing devices (9) are provided for release of the round hoist (8) in the compartment which is next in turn when the preceding compartment has been emptied. The recoil of the gun is employed for release of the round hoists.

IPC: H01H71/12
Filed: 1987-05-12
Abstract: An electronically driven trip actuator for multi-­pole industrial rated molded case circuit breakers is installed within a common housing with the circuit breaker operating mechanism. The trip actuator (27) consists of a mechanical actuator (29) cooperatively connected with a magnetic latch. The magnetic latch arrangement holds the trip actuator against an actuating spring bias (33). Upon receiving an appropriate signal response, the mag­netic latch releases, allowing the mechanical actuator to move into contact with the circuit breaker latch under the influence of the actuator spring. The ar­rangement of the mechanical actuator and actuator spring provides a low latching force to the magnetic latch, while providing a large trip force to the circuit break­er latch.

Abstract: An abradable ceramic coated turbine shroud structure (1) includes a grid of slant-steps (3) isolated by grooves (14) in a superalloy metal shroud substrate. A thin NiCrAlY bonding layer (8) is formed on the machined slant-steps. A stabilised zirconia layer (19) is plasma sprayed on the bonding layer (8) at a sufficiently large spray angle (18) to cause formation of deep shadow gaps (22) in the zirconia layer (19). The shadow gaps (22) provide a high degree of thermal strain tolerance, avoiding spalling. The exposed surface of the zirconia layer (19) is machined nearly to the shadow gap ends. The turbine blade tips (4) are treated to minimise blade tip wear during initial abrading of the zirconia layer (19). The procedure results in very close blade tip-to-shroud tolerances after the initial abrading.

Abstract: A digital robot control includes a position/­velocity microprocessor control and a torque microprocessor control for each of multiple robot axes. Digital position, velocity and motor current feedback signals are generated from motor sensor signals for use in making microprocessor control calculations. Another motor sensor generates an overlimit signal when motor temperature rises above a limit value to indicate excessive motor current. The torque microprocessor makes a backup motor energy calculation from the feedback motor current signal from each joint motor and compares the result to a stored motor energy limit. A backup velocity determination is made for each joint motor by the torque microprocessor from the motor current feed­back, the motor command terminal voltage and the motor resistance and inductance. The robot is shut down if the temperature or motor energy limit is exceeded or if the difference between the feedback and backup velocity values exceeds a predetermined limit.

Abstract: Processes characterized by dissolving a dye in a solution of organic solvent and an epoxy resin type polymer, which requires a curing agent in order to create a resultant nanosphere that will crosslink through the action of the curing agent, and not simply as the result of a solvent removal which defined each nanosphere. The dye may be in a concentration range of 1% to 50% by weight of solvent, and the organic solvent must have limited solubility in water, typically less than 20%. An initial intermolecular mixing step dissolves dye and epoxy resin within a solvent so as to make a homogeneous solvent/polymer/dye intermediate mixture, that then is dispersed as nanoparticles in water, and thereafter crosslinked. Surfactants may be used to assist in dispersing the dye/polymer/solvent solution into the water continuous phase.

Abstract: In a propagation time detecting system wherein a transmitting station transmits to a receiving station through a plurality of transmitting lines of different propagation times a transmission signal comprising a sequence of transmission data digitized by a clock signal of a clock frequency. The receiving station receives the transmission signal through the transmitting lines as different received signals and reproduces the sequence of transmission data and the clock signal as different reproduced sequence of transmission data and different reproduced clock signals from which differences are detected among the different propagation times. In order to improve accuracy of the detected differences, at least one subcarrier signal of a frequency higher than the clock frequency is also transmitted together with the transmission signal. The receiving station also reproduces the subcarrier signal as different reproduced subcarrier signals which are compared with each other to produce time differences therebetween with a reduced time order. In an application to a radar system, the transmission signal including the subcarrier signal is compared with an echo of the transmission signal from an target to produce a propagation time between the radar and the target.
