Title: Combination solenoid valve and shuttle valve with self-cleaning orifice.
Inventor: PICKETT MICHAEL GEORGE
IPC: B60T15/36
Filed: 1993-08-24
Abstract: The combination solenoid valve and shuttle valve (60) with self-cleaning orifice (92) comprises a shuttle valve (50) which is slidingly and sealingly received at an end (40D) of the solenoid valve (40). The shuttle valve (50) includes a stepped interior opening (54) which includes an insert (55) providing a shuttle valve seat (91) opposite a self-aligning solenoid valve seat assembly (94) of the solenoid valve (40). The valve seat (91) of the shuttle valve (50) includes an orifice (92) which extends from an end opening (70) of the insert and communicates with an insert passage (63) at an outer radial portion of the insert (55). An opposite radial side of the insert (55) includes a port (67) which communicates with a longitudinal passage (66) of the insert (55). Disposed within the longitudinal passage (66) is a brake-master cylinder check valve (59), and a stabilization check valve (58) adjacent a filter element (80) which permits communication with the insert passage (63). The shuttle valve (50) includes an end passage (64) having a pump check valve (57) and which communicates with an interior cavity (65) of the insert member (55). Fluid pressure from a pump mechanism (18) causes the shuttle valve (50) to be displaced and engage the shuttle valve seat (91) with the self-aligning valve seat assembly (94) so that fluid pressure from the pump mechanism (18) passes around the pump check valve (57), through the filter element (80) and insert passage (63), and out both ends of the orifice (92) for transmission to a second bore section (72) and a wheel brake (16) and to a first bore section (71) and a pressure producing device such as a master cylinder (12).

Abstract: Apparatus for the stacking of cuboid bales, with a trailer device (2) on a baling press (3), with a receiving surface (10) for the bales (5) leaving the baling press, with a stacking device for stacking two bales one on top of the other and with an ejector device, the stacking device having a supporting frame (6) and a gripper device, arranged above the receiving surface, for gripping and lifting a first bale, the gripper device being articulated on the supporting frame in such a way that it lifts the first bale, during the forward movement of the latter, as a result of a second bale pushing from behind, up to the height of the second bale. The method comprises the steps of gripping a first bale leaving the baling press by means of a gripper device mounted on a supporting frame, of lifting the first bale as a result of the advance of the following second bale up to a height which corresponds to the height of the second bale, the first bale moving from the gripping point to the point, at which lifting is terminated, on a circular path determined by the fastening of the gripper device on the supporting frame, of pushing the second bale forwards under the first bale, and of releasing the first bale when the second bale is located essentially under the first bale. The invention makes it possible to have an inexpensive apparatus for the stacking of, in particular, large bales having dimensions of a width of 1.20 m and a height of 0.70 m, without complicated control means having to be used. <IMAGE>

Abstract: Apparatus and a related method for generating a second harmonic frequency optical output from a fundamental frequency input beam, without significant birefringence. The apparatus includes two Type II doubler crystals (10,12) of equal length arranged with their corresponding axes parallel to each other, and a polarization rotator (14) positioned between the doubler crystals, to rotate the polarization angle of a residual fundamental frequency component of an output beam from one of the crystals by 90° or an odd multiple of 90°. Random birefringence introduced into one of the doubler crystals is virtually canceled in the other, and the assembly of the two crystals and the polarization rotator may be angularly adjusted as needed for phase matching or tuning, without detracting from the birefringence compensation capability. The invention is also disclosed in the context of a phase conjugated master oscillator power amplifier (PC MOPA) system.

Abstract: Propellant formulations are provided which include non-toxic burn rate modifiers. In order to produce a usable propellant formulation, it is necessary to control the burn rate of the propellant. Failure to adequately control the propellant burn rate often results in unacceptable performance of the propellant. It has been found that Group IIA metal salts, such as calcium carbonate and strontium carbonate, are capable of modifying the burn rate of propellants without resorting to lead as a burn rate additive. Accordingly, the use of from about 0.5% to about 5.0% Group IIA metal salt is taught as effective burn rate modifiers in propellants, in order provide non-toxic means for modifying the propellant burn rate.

IPC: B01J35/04

Abstract: A catalytic recombiner device for reacting two or more molecular species having dilute concentrations in fluids flowing in pipes (50) at elevated temperatures. The species are stable in the bulk fluid, but because of a high electrochemical potential, the species create conditions favorable to stress corrosion cracking in the pipe walls. If the pipe forms a portion of a coolant system, as in a nuclear power plant, the dissolved chemical species are transported and distributed throughout the system with undesirable consequences. To reduce the electrochemical potential, a cartridge (66, 80) having catalytic surfaces is installed in the flow upstream of the component to be protected against stress corrosion cracking. The catalytic surfaces of the cartridge form a small amount of benign reaction product (e.g. water), thereby reducing the concentration of undesirable species. The presence of a compact catalytic recombiner at strategic locations substantially reduces the electrochemical potential and protects both the piping and the vessels and internals connected to the piping from corrosive attack.

Abstract: A multiple execution unit processing system is provided wherein each execution unit 17, 19 has an associated instruction buffer 2, 4 and all instruction are executed in order. The first execution unit (unit 0) will always contain the oldest instruction and the second unit (unit 1) the newest. Processor instructions, such as load, store, add and the like are provided to each of the instruction buffers (0,1) from an instruction cache buffer. The first instruction (oldest) is placed in buffer 0 and the next (second) instruction is stored in buffer 1. It is determined during the decode stage whether the instructions are dependent on an immediately preceding instruction. If both instructions are independent of other instructions, then they can execute in parallel. However, if the second instruction is dependent on the first, then (subsequent to the first instruction being executed) it is laterally shifted to the first instruction buffer. Instructions are also defined as being dependent on an unavailable resource. In most cases these "unavailable" instructions are allowed to be executed in parallel on the execution units.
