New Technical Products S -BAND LOAD ISOLATORS S10 series of S -band Microwave Load Isolators provides higher isolation with 1/3 less space and weight. Engineered for min. size and weight, a wide variety of Litton isolators in the S10 series CONNECTORS These Amphenol Micro -Ribbon connectors, utilizing an improved version of the amphenol- developed "ribbon" contact design, have been developed for miniaturization programs. Amphenol CHASSIS KIT New 3 -D Chassis Kit provides complete flexibility in the construction of prototype models. Low -cost construction kit consists of: end brackets, side channels, terminal strips, miniature and offers reverse attenuation of 10 to 30 db or higher, with corresponding insertion losses of 0.5 to 1.5 db. The new S -band isolators can handle 500 kw. peak power and 250 w. average without external cooling. With air or liquid cooling, power handling capacity can be increased substantially. Litton Industries, Components Div., 336 N. Foothill Rd., Beverly Hills, Calif. and 251 S. Fulton Ave., Mount Vernon, N Y. TELE- TECH & ELECTRONIC INDUSTRIES (Ask for 4 -20) OUTPUT STANDARDIZER This new subminiature decade capacitor (silver mica) switch provides capacitance values from 10 mmfd to 9990 mmfd ( ±1 %) that is variable in discrete switch steps of 10 mmfd. The primary design use is for standardizing the voltage output from Endevco self -generating pressure, force, and acceleration pickups to one value of output voltage. reports that, using mating pairs of a widely used conventional connector, (left, in photo) 240 circuits weigh 11/2 lbs. and require 48 cu. inches of space - with mating Micro -Ribbons, (right in photo) 240 circuits weigh / lb. and take up 10 cu. inches of space. The new connectors are available in 14, 24 and 36 contacts. American Phenolic Corp., Chicago 50, Ill. TELE -TECH & ELEC- TRONIC INDUSTRIES (Ask for 4 -22) VARIABLE DELAY LINE This delay line is capable of providing continuously variable delay from 0 to 1 µsec. and more. The amount of equalization has been made exactly equal to its correct optimum value. Rise time less than 8% of the time delay at any point, no overshoot, excellent stability, hairline accuracy, and complete freedom of time jitter. The size is only 1 in. x 6 in. x 6 in. Three different models are available. The useful band- octal tube socket plates, component mounting boards, mounting brackets, double -end press -in terminals, self - tapping screws, potentiometer mounting plates. Plastic used in all mounting boards is laminated, paper base, XXXP (MIL -P- 3115), Type PBE. Overall size of the kit is 5 in. wide, 161/2 in. long and 31/2 in. high. Precision Metal Products Co., 41 Elm St., Stoneham 80, Mass. TELE -TECH & ELECTRONIC INDUS- TRIES (Ask for 4 -27) SERVO -GEAR -TRAIN A new size 11 servo- gear -train weighing only 6.875 oz. and consisting of a single homogeneous unit instead of two separate parts is now available. Everyone of these servo type units have linear speed torque characteristics, low inertia value, high stall torque values and low starting friction level. The gear train operates with load torques up to 25 in. -oz. and ,max. mo- This unit used as a pickup "standard - izer" establishes a preselected data scale factor. Groups of pickups may be standardized within a similarity of 1 %. Endevco Corporation, 161 East Calif. St., Pasadena, Calif. TELE -TECH & ELEC- TRONIC INDUSTRIES (Ask for 3 -22) width for all three types is over 10 Mc. The max. operating voltage is 500 v. peak and the ambilent temp. is from -55 °C to +125 °C. Advance Electronics Co., Inc., 451 Highland Ave., Passaic, N. J. TELE -TECH & ELECTRONIC INDUSTRIES (Ask for 3 -119) mentary load torques of 75 in. -oz. Backlash is 35 minute min. Gear ratios may be varied in convenient steps from 12:1 to 4000:1. John Oster Manufacturing Co., Avionic Division, Racine, Wisc.
