Patent CA-2071895-A1 (CA)
Inventor: ARVIDSSON THOMAS
IPC: F16D65/28
Filed: 1990-12-18
Abstract: An oscillating axial movement of a drive member (18) in a force actu-ator is generated by a prestressed rod (17) of Terfenol material being ex-posed to a pulsating magnetic field. This oscillating movement is trans-formed to an axial movement in an application direction of a push rod (21) coaxial therewith. The drive member and the push rod are connected by a connection member (22), which is in self-locking thread engagement with the drive member and the push rod and is subjected to a torque from a spiral spring (23) for its rotation during the idle stroke of the oscillation movement in the direction for advancing the push rod in the application direction.

Patent CA-2092987-A1 (CA)
Inventor: BLANKENSHIP ROBERT M
IPC: C09D7/65
Filed: 1993-03-30
Abstract: ABSTRACT OF THE DISCLOSURE     The present invention is concerned with core and shell polymeric particles having microvoids in the core and one or more channels connecting the microvoids to the exterior of the particle. These particles, or LCAPs are produced by forming a core of polymeric acid, encasing the core in a shell polymer permeable to base, and then neutralizing the core such that the core swells, causing the shell to "explode" in a controlled fashion. This controlled explosion causes channels to form in the shell.     These particles can be used as control release devices for target compounds, to impart reinforcing properties to acrylic films, as an opacifying agent in coating compositions, and as a supplement or replacement of part or all of the pigmentary material or extenders that would otherwise be used in such coating compositions.

Title: Transmission system for transmitting signals in burst mode
Inventor: DE GROOTE JAN L B
IPC: H04L25/30
Filed: 1993-09-08
Abstract: The transmission system is for transmitting signals in burst mode. Transmitters in substations of the system transmit signals in bursts and, in dedicated timeslots, to a main station. The latter station converts the received signals to digital signals by means of a processing circuitry included in its receiver. This processing circuitry performs the steps of an iterative process and, in each step, derives from a received signal Iin a threshold value related to a characteristic of the signal. The power of the transmitted signals is controlled by a circuit that compares the peak power values of a maintenance signal coupled back via a backfacet diode D with reference values REF1 and REF2 and controls a laser circuit L based on the result of the comparison stored in a memory MEM2.

Title: Method of making absorbent wood pulp
Inventor: WARREN ELLEN A K
IPC: B01J19/08
Filed: 1993-12-06
Abstract: ABSTRACT OF THE DISCLOSURE A method of preparing highly absorbent wood pulp without the need for a post-decrystallization step is disclosed which involves the steps of irradiating wood pulp in the presence of air with high energy radiation, e.g., gamma rays, and reacting the irradiated wood pulp with one or more vinyl-substituted aliphatic carboxylic acid monomers in an aqueous medium at a temperature in the range of from about ambient temperature to about 100°C. The monomer can be present partially as an alkali metal salt, in which case the ratio of equivalents of alkali metal salt monomers to equivalents of carboxylic acid monomers in the aqueous medium is no greater than about 1.5. In the event the ratio of equivalents of alkali metal salt monomers to equivalents of carboxylic acid monomers in the reaction mixture is less than about 1, the reacted wood pulp is treated with an amount of an alkali metal hydroxide sufficient to provide a ratio of alkali metal carboxylate salt groups to carboxylic acid groups in the reactedwood pulp of at least 1. The ratio of the water retention value to the weight percent of monomers present in the wood pulp, based on the dry weight of wood pulp, is greater than about 0.16.
