Patent DE-3467528-D1 (DE)
Title: Speed control for manufacturing process
Inventor: POWERS LOREN C
IPC: B31B50/92
Filed: 1984-04-06
Granted: 1987-12-23
Abstract: Each box is folded in a gluer. As each box, in succession, transfers to the stacker mechanism a counter produces a variable width pulse. These pulses are converted into fixed width pulses with frequency proportional to the rate at which the folded paper boxes transfer to the stacker mechanism. The control circuit converts these fixed width pulses to constant energy pulses and integrates the constant energy pulses to provide a DC set point signal for a DC motor drive speed control circuit. During operation, the control assures that the stacker mechanism advances a fixed, incremental distance each time a folded paper box is received from the gluer. This ensures even spatial distribution of the boxes along the stacker mechanism.

Abstract: The document of value is provided with a safety design extending on one portion or the whole of its surface. The entire surface of the safety design consists of juxtaposed groups of segments of raised parallel lines of two different heights forming high reliefs and low reliefs portions. The segments of two adjacent groups are parallel to two predetermined directions, preferably substantially perpendicular. The assembly of segments parallel to one of the directions and consisting of high reliefs on the whole or part of their length define a transitory image visible when the document is illuminated or observed parallel to a direction perpendicular to said segments and forming an acute angle with the plane of the document of value. A second transitory image is formed in a similar manner by high relief segments parallel to the other direction. The low raised segments or segment fractions constitute the background of the safety design. All the raised segments and the gaps left between the segments have preferably the same color.

Abstract: A heavy support weapon, for example, of 30 mm caliber, designed for firing from conventional machine gun mounts without undue recoil loads transferred to the gun mount. The weapon is designed for first round accuracy whether in the automatic open bolt or semi-automatic closed bolt mode. The weapon 10 includes a barrel 13 joined to a barrel yoke 21 in a receiver 14 aft of a front housing assembly 15. The recoil system includes a main recoil spring 30, a secondary spring 23, a buffer group including rods 60, springs 61 and plate 63. A slide bolt assembly 40 includes a slide 41, a bolt 42, a face 43, bolt face levers 44 and actuating pins 45, all within the receiver 14.

Abstract: In an NMR system, two chemical shift components are separated by correcting NMR data for field inhomogeneity. A first image data set is acquired which contains no chemical shift information or field inhomogeneity. A second image data set is acquired which contains both chemical shift information and field inhomogeneity. A third image data set is acquired which contains field inhomogeneity information. The first and third image data sets are combined to identify the field inhomogeneity information. This intermediate field image is then used to correct the second image data set for field inhomogeneity. The first image data set and corrected second image data set may then be combined by magnitude reconstruction of complex sums and differences to separate the two chemical shift components.

Abstract: Phenol sulphonate esters can be made in a known process by reacting an alkali metal phenol sulphonate salt with an acyl halide in a hydrocarbon solvent at elevated temperatures, but the use of anhydrous materials were strongly advocated because any residual water hydrolyses the acyl chloride in a competitive reaction. However, it becomes particularly difficult and expensive to dehydrate phenol sulphonate salts below about 2% w/w water on a commercial scale and the product obtained by reaction from such partly dehydrated salts can be comparatively impure or reduced in yield. Consequently, changes to the process such as omitting the solvent or using a different acylating agent have been proposed, but these alternatives introduce their own respective manufacturing problems such as entrainment of viscous acyl chloride and anhydride in the product or introduction of a cumbersome and hence expensive recovery process involving an extra distillation step amongst others. The present invention provides a surprisingly convenient modification to the known process in which the esterification and product separation steps are incorporated into a cycle together with an acyl halide preparation step in which residual carboxylic acid and anhydride in solution after product separation is preferably augmented with a replenishing amount of carboxylic acid and then reacted wtih thionyl halide. The resultant ester is readily separable and is obtained in comparatively good yield.
