Title: Amorphous precipitated silicas and methods for their preparation
IPC: A61K8/25
Filed: 1975-05-21
Abstract: A method for producing precipitated silica products having a unique combination of physical and chemical properties is disclosed. The products are produced by acidulating a solution of an alkali metal silicate with an acid under carefully controlled precipitation conditions. In accordance with the method, at least a portion of the alkali metal silicate solution theoretically required to react with said acid is initially charged to the reaction vessel. Thereafter, the remaining silicate solution and the acid are simultaneously added to the reaction vessel in a manner to control the alkalinity of the reaction medium. By controlling the percent of the silicate solution initially charged to the reaction vessel, silicas having predetermined properties can be obtained. Properties of the products include low wet cake moisture content, low structure, low oil absorption, high abrasivness, and low void volume. The products can be used as abrasive and polishing agents in dentifrice compositions. In one particular advantageous embodiment, an adduct material, such as aluminum, is added to control the refractive index of the product.

Title: Automatic luminance channel frequency response control apparatus
IPC: H04N5/208
Filed: 1975-10-21
Abstract: A delay line suitable for television video signals is included in the luminance channel of a television video signal processing apparatus. A plurality of taps are coupled to the delay line for developing a plurality of delayed video signals. At least a first and a second of the delayed video signals are combined in first combining means to produce a first combined signal which determines the peaking characteristics of the luminance channel. A bandwidth determining signal is derived from at least a third one of the delayed video signals located in time between the first and the second delayed video signal. A second bandwidth determining signal is derived from at least a fourth and a fifth of the delayed video signals located in time between the first and the second delayed video signals. One of the bandwidth determining signals and the first combined signal are combined in a second combining means to produce a second combined signal. The first and second bandwidth determining signals are combined to produce a third bandwidth determining signal which includes controllable amplitude portions of the first and second bandwidth determining signals. The third bandwidth determining signal controls the overall bandwidth characteristics of the luminance channel. The third bandwidth determining signal and the second combined signal are combined to produce an output signal. In one embodiment, the formation of the third bandwidth determining signal is dynamically controlled in response to a signal representing the amount of color information contained in the video signals so as to increase the bandwidth of the luminance channel when the amount of color information is relatively low to thereby improve the fine detail resolution and transient response of the receiver.

Title: High frequency dimmer circuit for high intensity, gaseous discharge lamp
IPC: H05B41/392
Filed: 1979-08-02
Abstract: A dimmer circuit for providing gate signal to a gated semiconductor connected for at least partial bypass operation of a ballast element of an HID lamp, the gate signal being derived from a high frequency voltage in a predetermined range. The high frequency voltage is separated from other frequencies and converted to a voltage proportional to the frequency. The voltage is then converted to a pulse within the timed operational limits of the line voltage for gating the semiconductor, and hence producing a brightness of the lamp between predetermined limits of full dim to full bright. Preferably, the high frequency voltage carrying the control information arrives superimposed on the line voltage to thereby avoid having to use a separate set of leads to the lamp to provide light level control signalling.

Title: Variable-gain differential amplifier
IPC: H03G1/00
Filed: 1980-12-19
Abstract: A variable-gain differential amplifier comprises a first long-tailed transistor pair between the bases of which the input signal is applied. The emitter-collector paths of the transistors of the first pair are included in the tails of second and third long-tailed transistor pairs respectively, and load resistors between the lower terminals of which the output signal appears are included in the respective collector circuits of one transistor of each of the second and third pairs, and hence in the collector circuits of the respective transistors of the first pair. The second and third pairs are controlled by a gain control signal thereby diverting a variable proportion of the collector signal currents of the transistors of the first pair away from the load resistors (17,18) and hence varying the gain of the circuit. In order that variations in the gain control signal should not affect the d.c. level at the amplifier output the collectors of the other transistors of the second and third pairs are commoned and connected to the input of a current splitter the two output currents of which are fed to the respective load resistors, thereby compensating for any changes in the standing currents through the load resistors which would otherwise be produced by changes in the gain control voltage.
