Title: Process for incorporating aspartame into extruded products
Inventor: DEMASO PATRICIA
IPC: A23L27/30
Filed: 1983-08-12
Granted: 1987-05-14
Abstract: Dry comestibles, such as cereal products and baked-type goods having an L-aspartic acid sweetening derivative distributed substantially uniformly throughout the comestible as a substitute for sugar or other sweeteners, are obtained by combining the L-aspartic acid sweetening derivative, a pH adjuster, water, and the remaining dry ingredients of the comestible to form a dough, extruding the dough through an extruder die plate, cutting the extruded product into pieces, and optionally reducing the moisture content of the pieces by conventional means like drying or toasting. The most feasible method of combining the ingredients is to separately feed: a) an aqueous solution of the sweetening derivative having a pH adjusted to about 1.0-7.0, preferably 2.0-3.0, and b) a preblended mixture of the remaining dry ingredients to the extruder wherein they are admixed to form a dough. Decomposition of the L-sapartic acid sweetening derivative during processing is minimized by controlling the pH of the sweetener solution, and the exposure time of the sweetener to high temperatures throughout the process for producing the dry comestible. The extruded dry baked comestibles are highly palatable, do not look sugar coated, do not contain localized concentrations of the L-aspartic acid sweetening derivative and are shelf stable for extended periods of time.

Title: Control system for a line printer having an endless type carrier
Inventor: CARRINGTON JAMES EDWARD
IPC: G06K15/08
Filed: 1983-11-03
Granted: 1987-05-27
Abstract: This control system for a multispeed/multipitch line printer basically comprises two read/write memories called the Band Image Buffer (19) and the Print Line Buffer (17). The Band Image Buffer (19) is loaded with the character image of the print band or chain (10) and can be visualized as an electronic band running in synchronism with the type carrier (10). The Print Line Buffer (17) is loaded with a line of data to be printed. Both buffers (17, 19) are read during each option time of a print subscan, their contents are compared in a comparator (47)-which controls the hammer firing circuits (51, 53)-, and their respective address registers (23, 22) are modified to a new value at the end of each subscan. A control bit is stored in a check buffer (20) to detect the end of each subscan. Comparison of the contents of the Band Image and Print Line Buffers (19, 17) continues until the control bit is detected signifying that a Band Image Buffer correction cycle followed by a Print Line Buffer correction cycle should be performed.

Title: Device for supporting rails for railway vehicles
Inventor: ORTWEIN HERMANN JOSEF
IPC: E01B9/62
Filed: 1983-08-03
Granted: 1988-03-17
Abstract: A mount for a railroad rail having an inner side turned toward another such rail and an outer side turned away from the other rail has a one-piece base supported on the ground under the one rail and formed with an upwardly open recess having inner and outer base flanks respectively generally under and parallel to the inner and outer sides, the outer base flank being formed as an inwardly overhanging ridge. An insert attached to the rail and received in the recess has respective inner and outer insert edges, the former of which is overhung by the ridge. An elastomeric body lies between the inner flank and inner edge and supports the insert in the base. Due to the overhang of the base edge, it is possible to make the base in one piece at least outward from a location underneath the rail. Thus there is no need to make the base from two parts split along a horizontal plane and requiring tedious assembly in the field.

Granted: 1986-11-20
Abstract: A cross-flow water turbine has a casing, a runner, a horizontal inlet and a vertical outlet. The inlet is divided by a pivoted guide vane to form a pair of inlet passages. A horizontally extending admission passage is connected to the casing at the inlet side thereof, and a vertically extending discharge passage is formed as a draft tube and connected to the casing at the outlet thereof. The inlet and the guide vane are arranged such that the inlet flow to the runner is directed downward at an angle of about 40 DEG  with respect to the horizontal, and the outlet flow from the runner is directed substantially vertically. At the outlet there are a pair of side spaces on either side of the runner resulting in an increased cross section conforming to the cross section of the draft tube. Both of these side spaces are vented to the atmosphere by a single venting valve so that the suction pressure in the draft tube does not exceed a predetermined value.

Title: Centrifugal governor for a fuel injection pump regulator
Inventor: KRAMER MANFRED DIPL ING
IPC: G05G25/00
Filed: 1986-06-04
Granted: 1988-10-13
Abstract: A centrifugal adjuster for a fuel injection pump governor having a driving part driven at an rpm in synchronism with the engine and having a torsionally elastically coupled flyweight holder guided in a rotational guide. Via a step, beyond a predetermined rotational deflection, the centrifugal adjuster displaces the flyweight holder axially with respect to the driving part, so that a jolt-like stroke effected by means of the step is superimposed on the regulating stroke effected via the flyweights of the centrifugal adjuster whenever the rpm is at a low level, for instance at idling rpm. As a result, a friction that leads to see-sawing of the engine and exhibits pronounced hysteresis is shaken out of the governor.
