Abstract:
A thermoforming trim press has one or more connecting arms for driving a movable platen, each arm having a pivotal connection between two adjacent sections of each connecting arm which is normally locked during normal press operation whereby the movable platen is able to move further back from a normal retracted position to increase the available clearance when changing or maintaining tools mounted on the movable platen. The pivoting ability of the connecting arm sections also simplifies adjusting the stroke of the press. A counterweight may be driven by the crank pins to match the press stroke adjustments and to thereby correspond the movement of the counterweight to the movement of the movable platen.
Abstract:
A thermoforming trim press has one or more connecting arms for a movable platen which each have a pivotal connection between the adjacent ends of two adjacent sections into which each connecting arm is divided. The pivotal connection is normally locked to keep the sections in end to end alignment during normal press operation, but can be released to allow pivoting between the sections to be able to draw the movable platen further back from the normal retracted position to increase the available clearance when changing or maintaining tools mounted on the movable platen. The pivoting ability of the connecting arm sections also simplifies adjusting the stroke of the press while this is normally done by relocating a crank pin on flywheels driving the connecting arms. The change of position does not affect the movable platen when the arm sections may pivot with respect to each other allowing relocating the crank pins to adjust the stroke without requiring disassembling of the crank pins. A counterweight may be driven by the crank pins to match the press stroke adjustments and to thereby correspond the movement of the counterweight to the movement of the movable platen.
Abstract:
The present invention concerns tunable distributed Bragg reflector (DBR) semiconductor lasers, in particular a DBR laser with a branched optical waveguide 5 within which a plurality of differently shaped lasing cavities may be formed, and a method of operation of such a laser. The laser may comprise a phase control section (418), gain section (420, 422), a sampled grating DBR (412) giving a comb-line spectrum and two tunable, chirped DBRs (414, 416) for broadband frequency training and a coupling section (410).
Abstract:
A tuneable laser has a gain section bounded at one end by a first reflector in the form of a distributed Bragg reflector adapted to produce a comb of reflective peaks and on the other end by a second Bragg reflector, the second Bragg reflector adapted to reflect at a plurality of wavelengths and being capable of being varied selectively through discrete segments so that one or more segments of the Bragg reflector can be tuned to a lower wavelength to reflect with a segment reflecting at that lower wavelength to enhance the reflectivity at that lower wavelength.
Abstract:
A drive system for double toggle mechanisms used to move upper and lower platens with an electric servo motor-gear box drive shaft driving a crank arm arranged to drive a respective double toggle mechanism in turn connected to the platen. The drive shaft axis is located below the toggle mechanism link pivots and driven in a direction so that the motor acts to assist the double toggle mechanism in lifting the platen, reducing the servo motor peak load. The various components are arranged for symmetrical loading of the pivots concerning the toggle links to increase the evenness of the platen when being raised or lowered.

Abstract:
The present invention is a method for enabling a trusted dialog for collection of sensitive data, including the steps of: storing a personal security token specified by a user; receiving an input dialog request from an application; determining whether the application is a signed application; and, if a determination is made that the application is a signed application, accessing the personal security token and allowing the input dialog to be displayed with the personal security token and signed application identification. The personal security token may be at least one of an audible recording or a set of vibratory motions.
Abstract:
The invention relates to liquid sulphur-containing antioxidants and to compositions comprising them. The novel lubricant comprise the reaction product of a selected group of 5-tert-butyl-4-hydroxy-3-methyl(or tert-butyl)phenyl substituted carboxylic acid esters with thiodiethylene glycol and a mono-hydroxy alcohol with a carbon chain length higher than 4 C-atoms. The novel lubricant compositions are highly resistant to oxidative degradation and are capable of reducing the negative effects of deposits, such as black sludge, in motor combustion engines, particularly spark ignition internal combustion engines.
