Title: Method for the preparation of nickel hydroxide particles
Inventor: MAKIMOTO KUNINOBU
IPC: C01G53/04
Filed: 1994-10-20
Abstract: ABSTRACT OF THE DISCLOSURE         An improved process for the preparation of nickel hydrox-ide particles is proposed, by which the nickel hydroxide particles have an outstandingly spherical particle configuration with a rela-tively narrow particle size distribution to exhibit a high packing density of the particles. The nickel hydroxide particles are produc-ed by the precipitation reaction for which an aqueous solution of a nickel salt, ammonia water and an aqueous solution of a sodium hydroxide are concurrently and continuously introduced into a re-action vessel to form a reaction mixture consisting of the nickel hy-droxide particles and aqueous medium, from which the aqueous medium alone is withdrawn either continuously or intermittently so as to accumulate the nickel hydroxide particles in the reaction mixture contained in the reaction mixture resulting in growth of the nickel hydroxide particles to be imparted with desirable parti-cle characteristics.
Patent CA-2134648-A1 (CA)
Inventor: BACHER HELMUT
IPC: B29B9/06
Filed: 1993-04-26
Abstract: In a process for recycling blown plastics, the plastic is first ground, melted, and then is degassed and filtered.           The degassed plastic is re-blown in the same plant before it has solidified, and, in order to make the degree of blowing uniform, the quantity of gas introduced into the plastic is controlled in relation to the quantity of plastic taken to the blowing plant per unit time, and the pressure of the plastic taken to the blowing plant is preferably kept as constant as possible.  The device for implementing this process has an extruder to plasticize and degas the plastic, the outlet of which is connected via at least one line to a mixer to which a gas supply device is also connected.  In the line there is a melt pump for the plastic, the flow rate of which is used as a guiding factor for the gas supply.           The gas supply is provided via a device which is controlled by a control device in proportion to the running speed of the melt pump.

Title: High loop density pin seam
Inventor: SCARFE ALFRED
IPC: D21F1/00
Filed: 1994-03-14
Abstract: 2135159 9421847 PCTABS00033 A pin seam for use in woven papermaking fabrics, wherein more than 50 % of the warp strands from each of the fabric ends are used to form the pintle retaining loops. The loops formed at one of the opposing fabric ends have an "S" orientation, while the loops formed at the second opposing end have a "Z" orientation, thereby allowing the two sets of pintle retaining loops to interdigitate easily. The resulting seam is strong, easily installed on the papermaking machine and has a reduced propensity to mark the paper web. The invention is particularly applicable to fabrics woven using 3-shed weave patterns or integral multiples thereof.

Title: Multi-segment vector quantizer for a speech coder suitable for use in a radiotelephone
Inventor: GERSON IRA A
IPC: G10L19/135
Filed: 1994-03-07
Abstract: A Vector-Sum Excited Linear Predictive Coding (VSELP) speech coder provides improved quality and reduced complexity over a typical speech coder. VSELP uses a codebook which has a predefined structure such that the computations required for the codebook search process can be significantly reduced. This VSELP speech coder uses single or multi-segment vector quantizer of the reflection coefficients based on a Fixed-Point-Lattice-Technique (FLAT). Additionally, this speech coder uses a pre-quantizer to reduce the vector codebook search complexity and a high-resolution scalar quantizer to reduce the amount of memory needed to store the reflection coefficient vector codebooks. Resulting in a high quality speech coder with reduced computations and storage requirements.
