Abstract: The invention relates to a method and an arrangement for producing a flow of stock in a moulding tank (1). In this, stock is pumped into the moulding tank (1) at the bottom (1a) and allowed to flow up over the brim (1b) thereof.  During its rise in the moulding tank (1), the flow of stock pumped in is distributed by at least one grating placed essentially horizontally and provided with flow openings. An arrangement for performing the said method comprises a line (2a, 2b), connected to the moulding tank (1) and a machine vat for ready prepared stock, for delivering fresh stock to the moulding tank (1) by means of a pump (5) connecting with the line (2a, 2b). The line (2b) opens out in an area close to the bottom (1a) of the moulding tank (1) in such a way that an upwardly directed flow of stock is obtained. The pump (5) is adapted to deliver excess stock so that excess stock is allowed to flow over the brim (1b) of the moulding tank (1).

Abstract: Passive elastic and resistance values for a particular patient are estimated during proportional assist ventilation (PAV) and other forms of assisted ventilation to permit reliable adjustment for volume-related and flow-related assist gains to meet continuously varying patient muscle pressure (Pmus). Independent but simultaneous procedures are effected to determine the respective values. The pressure-volume relationship is determined by a modification of the inspiratory hold technique while the pressure-flow relationship is determined by deliberately introducing brief perturbations in pressure (Paw), flow and volume (V) and observing the effects obtained.

Abstract: A float current probe measuring a float current flowing in a conductor comprises a core adapted to be magnetically coupled to the conductor. Excitation and field cancellation windings are magnetically coupled to the core. A detector detects when energy in the excitation winding reaches a predetermined threshold corresponding to a saturated core condition. A timer measures first and second delays needed to saturate the core as a result of the excitation winding being energized through a switch circuit in the forward and reverse polarity successively. A computing unit determines a magnetic field induced by the conductor based on the first and second measured delays. The field cancellation winding is energized by a current source with a current level and direction as a function of the computed magnetic field, to cancel the magnetic field induced by the conductor. The current level is representative of the float current in the conductor.

Title: Method and system for generating messages including a verifiable assertion that a variable is within predetermined limits
Inventor: CORDERY ROBERT A
IPC: H04L9/32
Filed: 2000-12-08
Granted: 2005-09-20
Abstract: A method and system for generating messages from which it can be verified that a variable does not exceed a predetermined limit. The message can be a postal indicium. A message originator, which can be a postage metering system, receives a message in the form R-K(T), where R is a trapdoor function, K is an integer equal to the limit, and T is a plain text, from a data processing center which maintains the inverse function R-1 in secrecy. The message originator computes S m =   R m(R-K(T), where m is a current value of the variable, and incorporates S m into the message. A verifier verifies that m < K by confirming that R K-m(S m) = T. The verifier cannot compute R K-m(S m) for m < K since it does not have R-1.     For the same reason the originator cannot compute R-K'(T), k' > K, from R-K(T).

Inventor: LOU HUI-LING
IPC: H04L1/00

Granted: 2005-01-04
Abstract: Improved techniques for multilevel coding of a stream of information bits in a communication system are disclosed. The stream of information bits is separated into portions, and each of the portions is associated with a different level of the multilevel coding. At least one code is applied to the portion of the information bits of each level in a designated subset of the full set of levels, such that the portions of the information bits for levels in the designated subset are coded while the portions of the information bits for levels not in the designated subset are uncoded. Both the coded portions of the information bits and the uncoded portions of the information bits are used to select modulation symbols for transmission in the system. Advantageously, the invention provides improved coding gain relative to conventional techniques, and can be configured to provide unequal error protection as well as time diversity for transmissions in the system.

Abstract: Adhesion of a thermosetting powder coating to a glass substrate surface using a silane adhesion promoter, is enhanced by modifying the pH of the glass surface to between 3.5 and 5, prior to, or during, the action of the promoter. The pH-modification may be effected during washing of the surface prior to spray-application of the promoter, or by including an acid or alkali modifier in the silane solution.  Alternatively, the silane, or the silane and the modifier, may be included in the thermosetting powder to become active during fusing of the powder to the glass surface. An acid or alkali solution dried on the surface prior to application of the promoter for activation with the promoter on heating, may be used instead or in addition.
