    摘要: A direct acting hydraulic valve lifter of the type that is reciprocably journaled as in the cylinder head of an internal combustion engine so as to be engaged by a cam on an engine driven camshaft to control opening and closing movement of an associate valve. The lifter includes a follower body having a circular outer tubular wall with an inner integral web closely adjacent to one end thereof that terminates at a stepped bored integral depending piston, the one end thereof being closed by a disk cam engaging foot which forms with the piston and a surface of the web a fluid reservoir. A baffle, fixed to the plunger and to inner surface of the tubular wall, defines an oil supply passage which is adapted to receive fluid via a side port in the tubular wall and to be in flow communication with the fluid reservoir via an aperture in the web. A cup-shaped, closed end cylinder member slidably encircles the plunger to form therewith a hydraulic lash adjuster having a pressure chamber therein. In one enbodiment, a mechanical retainer is operatively secured to the tubular wall whereby to retain the cylinder member in unit assembly on the plunger. In a preferred embodiment, lubricating oil in the pressure chamber and in a leak-down flow path between the cylinder member and plunger and a one-way ball valve controlling flow into the pressure chamber are operative to hold the cylinder member in unit assembly on the plunger.

    摘要: A process is provided for the manufacture of titanium dioxide pigment wherein excess ilmenite ore is reacted with dilute sulfuric acid having a concentration of between about 25% and about 60% by weight in the presence of an iron reductant, and in preferably at least two stages wherein the first stage is maintained at a temperature up to about 140.degree. C. and the second stage is conducted at a lower temperature (than the first stage) which is below about 100.degree. C. to provide a salt solution of titanium and iron. Thereafter, the titanium is hydrolyzed to provide titanium dioxide hydrate accompanied by recycling the spent acid from the hydrolysis for reaction with the ilmenite ore charged to the process. The titanium hydrate is calcined to provide titanium dioxide pigment.

    摘要: A process is provided for the manufacture of titanium compounds and particularly titanium dioxide wherein excess titaniferous bearing material is reacted with dilute sulfuric acid having a concentration of between about 25% and about 60% by weight at a temperature below about 140.degree. C., and in the presence of a reducing agent which affects the reduction of ferric iron to ferrous iron. Thereafter, the titanium sulfate may be recovered or further processed to provide titanium dioxide hydrate accompanied by recycling the spent acid for reaction with the titaniferous bearing material charged to the process. The titanium hydrate may be calcined to provide titanium dioxide.

    摘要: An alarm switch adapted to be mounted on the wall above a door on the side of the wall toward which the door swings open, having an electrically conductive arm adapted to be set in a position for actuation by the door, when the door swings, to swing inwardly and then upwardly into engagement with a terminal of the switch to complete an alarm circuit. The arm has a finger at its free end adapted to be set in a downwardly extending position for engagement by the door and a raised position clear of the door for deactivating the switch.

    摘要: An alarm switch is mounted by means of a support for actuation by relative movement between the support and a member such as a door or window. Switches are carried by the support and an operating arm for the switches extends from the support and is adapted to be pulled a limited distance relative to the support for actuating the switches to complete an alarm circuit. Interengageable gripping members on the arm and the member pull the arm the limited distance relative to the support to actuate the switches when there is relative movement between the member and the support, and automatically disengage to free the member from the arm when the relative movement is greater than the limited distance. The gripping members are selectively disengageable to permit relative movement between the support and the member without actuating the alarm switch.
