Abstract: Precipitated silica compositions, and methods for making the same, with improved dentifrice performance characteristics. In particular, precipitated silica compositions of the present invention have a 40% slurry viscosity build of less than approximately 20,000 centipoise and a 10% Brass Einlehner abrasion value of approximately 2.5 to 20.0 mg loss/100,000 rev. Precipitated silica compositions of the present invention also have reactor slurry average particle sizes (50%) of approximately 10 to 50 .mu.m. Methods for preparing precipitated silicas of the present invention include the steps of: (a) adding sodium silicate and a mineral acid to a reactor, thereby initiating a precipitation reaction between the reactor contents; and (b) subjecting the reactor contents to shearing forces as the reaction proceeds.

Abstract: The machine for collecting used cups enables collection of the cups in a container (2) in such a way as to reduce empty spaces between cups and thus better to utilize the volume of the container (2). A inlet for the cups, through which a cup (6) is inserted into the machine, is connected with a container (2) by means of a track, internal of the machine, on which an operative group (1) is positioned, which operative group (1) comprises a tubular body (11) for guiding a cup (6) on to a stack (9) of cups. The operative group (1) is mobile between a loading position, in which a stack (9) of cups (6) is created, and at least one unloading position, in which the stack (9) is unloaded into the container (2).

Abstract: An injection molding machine has a C-shaped machine frame with stationary die platen mounted on one limb and a closure mechanism mounted on the other for driving a movable die platen. The free ends of the machine frame limbs, whose ends are not connected by spars, deform under the influence of a closure force occurring during a closure process. Disposed between the stationary die platen and/or the closure mechanism, and the machine frame is at least one retaining part which deforms rather than pivoting, when the closure force is applied. The stationary die platen or the closure mechanism is thus tilted relative to the machine frame.

Abstract: A dispenser (1) comprises for its plunger chamber (13) an outlet valve (20) which after opening on the actuating stroke continues to remain open for a time during the subsequent return stroke due to a delay means (30) so as to ensure a more or less complete venting or filling of the plunger chamber (13). At the end of the delay period the closure maintained in the open position position by friction surface areas (37, 38) is released and automatically jumps back into its closed position. After venting, the effectiveness of the delay means (30) diminishes so that in normal operation substantially only a pressure dependent opening and closing of the outlet valve (20) is provided for.

Abstract: When in operation, devices for telecommunications installed in rooms generate a considerable amount of heat. This takes place continuously, and a maximum temperature must not be exceeded. In order to obtain reserve time for an air cooling system having a reserve time system with a guaranteed low temperature level of the liquid for the reserve time system, an evaporator (2) for the air cooling system is provided with a liquid circuit (2b) which is connected with a liquid tank (7). Liquid is circulated continuously through the evaporator with the liquid circuit, where it is cooled by the cooling medium for the air cooling system, at the same time as the inside air is cooled by the same evaporator. The continuous cooling and circulation of the liquid in the tank ensures that there is always the coldest possible liquid available when the ordinary cooling system is not working.
