Title: Land vehicle suspension control system
Inventor: WILLIAMS DAVID A
IPC: B60G17/015
Filed: 1990-05-04
Abstract: The invention provides a land vehicle suspension control system comprising means for measuring forces acting between the sprung mass of the vehicle (the body of the vehicle) and unsprung masses (wheel and hub assemblies) connected thereto, means for producing signals proportional to the resulting measured force values, means for determining from the signals the values of the forces required to be applied between the unsprung masses and the sprung mass to minimise force changes experienced by the sprung mass, means for determining the values of demanded relative velocities required between the sprung mass and the unsprung masses to satisfy the force requirements and means for applying the required forces between the unsprung masses and the sprung mass of the vehicle in proportion to the values of the relative velocities required between the sprung mass and the unsprung masses. The invention provides an active suspension control system, the outputs of which correspond to velocities required of the actuators of the system rather than the displacements required of the actuators. The invention provides means by which the actuators can be effectively controlled by velocity demands, with necessary feedback to ensure accurate control.

Title: Dual alloy turbine blade
Inventor: BORNS FREDERICK G
IPC: F01D5/28
Filed: 1990-07-18
Abstract: A composite turbine blade (20) having a single crystal airfoil section (22), a single crystal platform (26), and a composite attachment section (24). The attachment section (24) is comprised of a thin layer (34) of single crystal material overlying and metallurgically bonded, along interfacial bond lines (36), to a core (30) made of a fined grained, polycrystalline superalloy. The layer (34) has an external configuration having ridges (27) and grooves (28) for removably attaching to a complementary groove in a turbine disk. The blade is prepared by casting a single crystal body with a cavity within the attachment section (24), and then filling the attachment section with the polycrystalline superalloy to form a composite structure. Filling is preferably accomplished by plasma spraying the cavity with the superalloy, and hot isostatically compacting the sprayed superalloy to minimize porosity. The composite structure is then heat treated to develop an optimized microstructure in the dual alloy attachment section (24). The resulting turbine blade (20) has improved life resulting from reduced low cycle fatigue susceptibility of the composite attachment section (24).

Abstract: A system for employing a computer to control a device to provide a plurality of services for a plurality of entities. Each entity corresponds to exactly one of the services and each service has its own copy of the code which defines the service. The system associates a process which executes the service with each service. The code for a service defines a finite state machine which is continually executed by the service's process. While in a given state, the finite state machine may traverse a decision graph which is directly accessible to the process. Actions to be taken on traversal of a node of the decision graph may be defined in the finite state machine. The service's process communicates with other processes and with itself by meansof interprocess messages. Each state of the finite state machine contains event handlers for responding to messages received by the service's process. The finite state machine is defined by a special language, the service logic language, and the decision graphs are defined by means of a graphical editor. The compiler for theservice logic language produces not only C++ code defining the finite state machine, but also data base and shell scripts which are used to provision and maintain the services. An embodiment of the system is  disclosed which is used in a service node of a telephone switching network to provide telephone services such as 800 number service, caller ID, and the like.

Abstract: DRIVE FOR AUTOMATIC LANCE-CHANGING DEVICES      ABSTRACT           The  invention  relates  to  a  drive  for  an automatic lance-changing device, such as is used,  for example, in steel by making the top-blowing process. Such a lance-changing device comprises two lance-receiving hooks           pivotable about a horizontal axis of rotation, means for the synchronous vertical displacement of these hooks   relative to the lance carriage and to the coupling head     means which, during this displacement of the hooks,  cause these to execute a pivoting movement about their said axis of rotation, and means for detecting by measurement the load acting on each hook   , the latter being a function of the force with which the lance top part is pressed against said coupling head by the hooks.  The drive of this invention is a lifting-spindle system, by means of which a  vertically  displaceable  suspension  ring   for suspension hooks   of the lance top part is driven. This lifting-spindle system consists of at least two tie rods    the upper ends     of which are equipped with an external movement thread, and of at least two gearwheels, the hubs of which are equipped with a corresponding internal movement thread for interaction with said upper ends     .  These gearwheels are mounted axially/radially in a gear case  which itself rests on load cells  .  The latter cause the lifting-spindle drive to be switched off automatically when a predetermined pressure force between the lance top part   and a coupling head    is reached.         Fig. 1

Abstract: ONE PIECE CONCEALED NECKTIE HOLDER                         Abstract It is known that devices used to secure a four-in-hand necktie to a shirt, while being out of view, already exist.  This invention is an improvement to the patent application no. 2,055,090-2 filed 91/11/06 by the same inventor and owner.   In this invention the concealed necktie holder is made of a single piece of flexible translucent vinyl.  The device has rectangular shape, approximately 2 centimetres wide by 29 centimetres long and has two symmetrical halves, each 14.5 cm. long, that are designed to be folded one over the other when in use. It incorporates four longitudinally aligned button holes positioned in such a way that, when the device is folded, there are two superimposed button holes located at both extremities of the rectangular shape to match the spacing between shirt buttons. The device uses the necktie label, or any other narrow horizontal band attached to the back of the wide end of the necktie, and two adjacent shirt buttons to secure the necktie.  The design of this device, with its two symmetrical halves, was dictated by the two possible vertical positions of the necktie label relative to the shirt buttons. The two positions are: between two shirt buttons or directly in front of a shirt button.  To secure the four-in-hand necktie when the necktie label falls between two shirt button you keep the device folded, and simply slide both halves of the folded device between the necktie label and the necktie itself and then you button each end of the folded device to the two adjacent shirt buttons located each side of the necktie label.  For the other possibility when the necktie label falls directly in front of a button, you keep the device folded, holding it vertically with the fold at the lower end, but then you insert only one of the symmetrical halves between the necktie and its label, positioning the necktie label close to the folded end, then you fasten the top button holes of both halves of the device to the shirt button located immediately above the necktie label and finally you fasten only the lower button hole of the half next to the shirt to the button directly in front of the necktie label.  The device therefore enables the four-in-hand necktie to be secured to the shirt no matter where the label falls relative to the position of the shirt buttons.
