Abstract: A cellulose pulp continuous digester (e.g. for producing kraft pulp) is operated so that it has the advantages of a hydraulic digester yet has a gas-filled zone over the liquid level. A slurry of chips and cooking liquor is introduced into the top of the digester vessel through an inverted top separator. A liquid level is established below the inverted top separator, and a chips level is established below the inverted top separator (above or below the liquid level). A gas-filled zone above the liquid level includes compressed gas, and is at a temperature of less than 160 (preferably less than 120)°C and at a pressure of between 50-200 (preferably 80-150) psig. The digester may have a first diameter portion (about 3-5 meters) at the top and a second diameter portion (at least about seven meters) below the top, with the inverted separator in the first diameter portion, the liquid level in the first diameter portion, and the chips level in the second diameter portion.

Title: Method and apparatus for purging water from a whirlpool system
Inventor: GLOODT CARY
IPC: A47K3/10
Filed: 2001-04-06
Abstract: An apparatus (10) for removing standing water from the hydraulic plumbing system that circulates water in a whirlpool bath. The apparatus includes a pneumatic pump (50) fluidlly coupled to the whirlpool hydraulic plumbing system of a whirlpool bathtub (20), such that air pressure from the pneumatic pump can be used to flush standing water out of the hydraulic plumbing system after each use. A pneumatic plumbing system connecting the pneumatic pump to the hydraulic plumbing system is positioned substantially above maximum water level allowed in the tub and also substantially above the hydraulic plumbing system. The pneumatic plumbing system is connected in fluid communication with different portions of the hydraulic plumbing system, such that activation of the pneumatic pump (after the tub has been substantially drained) forces residual water from the whirlpool hydraulic plumbing system into the bathtub, where it can be conventionally drained.

Inventor: BALD HUBERT
IPC: B30B11/02
Filed: 2001-11-10
Abstract: The invention relates to a method and device for the compression of granular materials. On compressing granular material to give prepared products e.g.  concrete paving slabs, a resonance vibrator with an oscillating mass-spring system is applied, which may be energised by a controllable energiser to produce forced oscillation of a given frequency and oscillatory amplitude. The resonant effect, making use of the proximity of the inherent resonance frequency and the exciter frequency permits a reduction in the size of the exciter force. According to the invention, along with an adjustment of the exciter frequency the resonant frequency is also simultaneously co-adjusted by means of a suitable adjuster, in order to be able to make use of the resonance effect throughout the whole spectrum of the exciter frequencies to be carried out.

Abstract: In a roll nip (5) formed between a shoe press roll (1) having a concave, plane or slightly convex press shoe (11), a flexible jacket (15) and a hot counter roll (3), the jacket (15) may be damaged by the heat from the counter roll (3) upon a web break. To avoid this, the roll nip (5) is opened by removing one of the press shoe (11) and the hot counter roll (3) from the other, so that the jacket (15) resumes a generally cylindrical shape having an arched portion located across the shoe (11). Then, a force is applied inside the roll jacket (15), directed away from the roll nip (5), to tension the roll jacket (15) over the leading edge and the trailing edge of the press shoe (11), so as to reduce the height of arch of the arched portion over the shoe (11) sufficiently to ensure removal of the jacket (15) from contact with the hot counter roll (3). Preferably, the force against the inside of the jacket is applied by means of a tensioning shoe (61). Suitably, the tensioning shoe is operated by a linear actuator (59), e.g. a fluid actuator, carried by a support beam (17) that extends axially through the flexible jacket (15).
