Title: Turbine agglomerated calcium hypochlorite
Inventor: BRIDGES WILLIAM G
IPC: B01J2/10
Filed: 1991-05-17
Abstract: A feed material is obtained from mixing hypochlorous acid and a lime slurry: 2HOC1 + Ca (OH)2 ----> Ca (OC1)2.2H2O. The feed material is used to produce a hydrated calcium hypochlorite agglomerated particle that is produced in a turbine agglomerator and has a plurality of connecting links of recrystallized material bridging the small particles forming the agglomerate which has therein a plurality of pores created by the substantial evaporation of the layer of surface liquid. The surface tension and adhesion forced of the layer of surface liquid at least partially hold the agglomerated particle together prior to drying.

Filed: 1992-11-26
Abstract: On the inner surface of sensor element (1) made of proton conductive solid electrolyte with perovskite structure and enclosed at its lower end, a reference electrode (2) constituted of porous electrode is formed, and a measuring electrode (3) constituted of porous electrode is formed on the outer surface thereof. And, the reference electrode and the measuring electrode are gas-tightly separated by sealing material. The sensor prove is inserted into ceramic sensor holding cup (10) and both are fixed in such a way that a part of the measuring electrode (3) extrude into said holding cup. Then, by dipping the holder into molten metal (19)by facing its opening part downwards, a space contacting with molten metal is enclosed in the holding cup. Thereby, reduction of solid electrolyte constituting the sensor element can be prevented, and hydrogen concentration in molten metal can be accurately measured without direct dipping the sensor element into molten metal. Thereby, it is possible to provide a sensor probe and a method for measuring hydrogen concentration in which hydrogen concentration can be continuously measured for long period and an apparatus with smaller size can be made. <IMAGE>

Patent CA-2094814-A1 (CA)
Inventor: JOHNSON NOEL R
IPC: F16F15/027
Filed: 1991-09-30
Abstract: An air spring apparatus (10) has quick pressure release, and rapid air exhaust, capability by means of a relatively large di-ameter exhaust port (44) in a larger, primary air spring (12) which is controlled by the action of a smaller, secondary air spring (14). The secondary air spring (14) is equipped with a check valve (56) which controls the flow of air into the primary air spring (12). The rapid exhaust of the primary air spring (12) is effected by triggering the removal of air pressure from the secondary air spring (14) through a plurality of orifices (86) in a centrally disposed guide tube (52) which permits the collapse of the smaller air spring and the accompanying removal of a valve plate (48) from a relatively large diameter exhaust port (44) of the primary air spring (12). Once the exhaust port (44) in the primary air spring (12) has been opened, the air pressure in the primary air spring (12) is immediately lowered, and the load on the larger air spring causes rapid expulsion of the volume of air in the primary air spring (12) to permit its quick deflation and collapse to a predetermined minimum height.

Abstract: An improved load compensator for a spring counter-weighting mechanism including a snail cam to provide a constant counter-weight force is described. The cam provides a constant torque to a drum on which are wound cables for exerting a constant counter-weighting force. A manually operable device for altering the relative radial positions of the cam and drum varies the amount of the constant counter-weighting force. The cam is rotated with respect to the drum by a spur gear fitting within a ring gear fixed to the drum and rotated by a knob connected to an axle carrying a pinion gear engaging the spur gear. The spiral surface can be effectively reconfigured with respect to a portion of the cable fitting therearound.

Abstract: A mechanical device comprising; a base which is attached to the lower side of tables that are found on typical furniture at public telephone locations. The base has a hinge and a dashpot.      Attached to the base by the hinge is a frame and a piston. The piston interacts with the dashpot on the base. On the piston is a seal and which controls the interaction between the piston and the dashpot. A typical binder with spring closing covers is fastened to the frame by it's back cover with the back of the binder in a more or less vertical position when the binder is in the storage position. When not in use, the binder with it's book, hangs below the table. A rest protrudes from the table of the telephone furniture in a position where it supports the binder when the binder, on is's frame, is hinged forward and upward from below the furniture to a horizontal position in front of the table, and opened. The rest supports the binder while it is open. The binder with it's book is easily held open with light downward pressure on the front cover with one hand. When the downward pressure is released, the springs in the covers of the binder close the binder and it returns below the table. The speed of the return is controlled by the piston and dashpot device.
