Title: Switch mechanism with independent toggle actuators
Inventor: CAPEL DENIS
IPC: H01H5/18
Filed: 1980-02-12
Granted: 1982-07-06
Abstract: SWITCH MECHANISM WITH INDEPENDENT TOGGLE ACTUATORS Abstract of the Disclosure A switch mechanism includes a fixed contact bar on which two or more contacts may be mounted. A movable contact is associated with each of the fixed contacts. Two independent toggle mechanisms are provided, each responsive to a different pressure-responsive dis-placement actuator for selectively actuating one or more of the movable contacts. In one embodiment having two normally open and one normally closed sets of contacts, one toggle mechanism is connected by a sliding yoke to the movable contacts of one normally open set and the normally closed set, and the other toggle mechanism is connected by a second, independent sliding yoke to the movable con-tacts of the other normally open set and the normally closed set. Hence the normally closed contacts (which may be used to de-energize a compressor motor) are opened if either pressure limit is exceeded, but only the normally open set is closed which is associated with the tripped toggle mechanism. This may be used to indicate an alarm. Each toggle mechanism may be automatically resetting or require manual reset.

Abstract: 19.                   MAGNETICALLY ANISOTROPIC ALLOYS BY DEFORMATION PROCESSING        Abstract of the Disclosure This invention relates to magnetic alloys having an anisotropic magnetic structure produced by thermo-mechanical treatment in the absence of a maganetic field. The treatment calls for developing magnetic particles in an alloy by cooling such alloy in a controlled fashion from a first temperature at which the alloy is in a predominantly single phase state to a second temperature at which the alloy is in a multi-phase state and deforming the alloy to result in cross-sectional area reduction of at least 30 percent (corresponding to elongation of magnetic particles by a factor of at least 1.7).  Disclosed treatment leads to desirable magnetic properties, e.g., in Cu-Ni-Fe, Cu-Ni-Co, Fe-Al-Ni, Fe-Al-Ni-Co and Fe-Cr-Co alloys.  For example, in the case of Fe-Cr-Co, alloy properties such as remanence-to-saturation squareness ratio in excess of 0.90 and maximum energy product in the range of 0.6-8.0 MGOe are achieved.           Disclosed magnetic alloys are suitable for use in the manufacture of telephone ringers, relays, and electromagnetic transducers.

Inventor: VALKAMA ERKKI
IPC: D21B1/12
Filed: 1980-03-19
Granted: 1982-06-08
Abstract: ABSTRACT OF THE DISCLOSURE A process for mechanically producing groundwood from wood chips, the wood chips being treated, after pre-heating under pressure in a steaming chamber, in two steps in disk grinders operating under pressure, these disk grinders having feeding means of enclosed construction.  The groundwood coming from the first stepdisk grinder is conducted under the pressure of the steam generated in the blade interval of the grinder to the feeding means of the second step disk grinder.  The transport of the groundwood is performed along a pipeline which is directly connected to the feeding means of the second step disk grinder.  In said feeding means feeding problems arising from floating of the groundwood in the steam flow discharging from the second disk grinder against the ground-wood flow is eliminated by feeding into the pipeline water or a chemical solution, which increases to the specific gravity of the groundwood.

Abstract: Abstract A process for the separation of substantially pure NH3  and  substantially pure CO2 from a mixture containing NH3, CO2 and water is disclosed.          In this process NH3 is separated by rectification in an NH3-separation zone, the remaining liquid phase is fed to a CO2-separation zone where gaseous CO2 is separated by rectification, and the resulting liquid phase is fed from the bottom of this zone to a desorption zone, where virtually all NH3 and Co2 still contained in this liquid phase are separated as a gaseous mixture.          To improve the efficiency of the separation and to decrease the sensitivity of the process to fluctuations in the feed to the NH3-separation zone the process is characterized in that so much gaseous CO2 or a gaseous mixture containing CO2 is fed to the bottom of the NH3-separation zone that the composition of the liquid phase released in the bottom of the NH3-separation zone is not on the side of the boundary line rich in NH3.          Preferably also an amount of inert gas is intro-duced together with the CO2.

Abstract: - 13 -                   Case 4212 ISOTROPIC ETCHING OF SILICON STRAIN GAGES        ABSTRACT OF THE DISCLOSURE     A method of etching a silicon diffused resistance pressure transducer assembly (13) of a transducer (10) mounted on a glass base (14) providing a thin flexible area on the transducer in the region of the diffused resistors (15) and a thick rigid area in the region where the transducer is mounted to the glass base (14). To accomplish this, the transducer (10) is first bonded to the glass base (14) which is tubular, thus providing a circular area on the backside (16) of the transducer (10) open to ambient.  This open area is then filled with an isotropic etchant which etches silicon material but which has little effect on glass material.  Thus, the region of the diffused resistors (15) is etched out to provide a thin flexible area while leaving a thick area where the transducer (10) is mounted to the glass base (14).

Abstract: ABSTRACT OF THE DISCLOSURE       A wear member for use between a pair of relatively movable com-ponents of a railway vehicle and method of making same are provided herein. Such wear member comprises a metal support adapted to be supported on one of the pair of components and a liner attached to the metal support.  The liner is made of a polymeric matrix material which is reinforced by a metal structure having openings therein.  Such metal structure is disposed sub-stantially centrally between opposed surfaces of the polymeric material. The opposed surfaces include a smooth antifriction wear surface engageable by the other of the pair of relatively moveable components.  The liner is attached in position by metal members extending between the metal structure and the metal support through polymeric material disposed between the metal structure and metal support and its associated arm of the opposed surfaces with a plurality of welds welding the metal members in position between the metal structure and the metal support.  Such wear member is less sub-ject to wear and under normal pressure during use is less likely to have the tendency to "cold flow".  The wear member also has more self supporting structural strength and need not be used between confining bearing sur-faces which it serves to lubricate.

Abstract: ABSTRACT            Process for the concentration of fibrous material.            Process for the concentration of fibrous material in a mixture thereof with non-fibrous material, by causing an aqueous suspension of said mixture to flow upwardly to bring about settling out of material of reduced fibre content and formation of a fibre-enriched fraction above it, which is then separated.            In the process, the upward flow is made substantially non-turbulent, and is carried out with gas bubbles passing upwardly through the suspension, to increase the efficiency of separation of fibrous from non-fibrous material.            The process is specially applicable to the concentration of fibres in the fibrous product (mineral wools) formed by disintegrating silicate and like mineral melts, which commonly contain a relatively high proportion of granular material ('shot').

Abstract: ABSTRACT OF THE DISCLOSURE     This disclosure relates to a flow control device in which the discharge from the nozzle is kept at essentially the same volume rate of flow in spite of fluctuations in the hy-draulic pressure upstream from the device by providing a spray body that has a group of radially disposed channels which are perpendicular to the general direction of flow.  A flexible spray control washer spaced upstream from these channels re-sponds to hydraulic pressure by pressing into the channels and restricting the flow area of each of these channels in propor-tion to the applied hydraulic pressure.  In this way, the flow area within the chamber is inversely related to the hydraulic pressure in order to maintain a continuous volume rate of flow through the device.
