Title: Knitting needle cam drive - has a flattened profile in latch opening zone to reduce needle stresses
Inventor: DIETE SELMAR
IPC: D04B15/32
Filed: 1975-07-08
Abstract: Appt. is claimed for operating the latch needles of a knitting machine, where a cam activates the latches. The drive cam is so constructed that there is a flattening at about the point where latch opening starts, ranging approximately to the point where the latch is fully opened. Pref. the flattening of the profile of the drive cam between the start and end of the latch opening phase follows a mirrored S-curve in this zone. The flattened zone is profiled into a normal drive cam to change the total profile. The design reduces the stresses imparted to the needle in its control and latch opening, so that higher knitting speeds can be achieved without damaging the needles.

Title: Three:phase supply monitor circuit - phases connected to resistive divider and diode rectifier for simultaneous detection of voltage, symmetry and phase succession
Inventor: STEIN PETER L
IPC: G01R29/16
Filed: 1975-08-28
Abstract: The three-phase AC supply monitor circuit simultaneously detects voltage, symmetry and phase relationship. The three phases are connected to a resistive divider and diode rectifier. A voltage-follower transistor fed from the rectifier, charges a capacitor. If the voltage of all three phases is the same, current pulses of equal amplitude appear at the output of a second transistor. No pulse is produced if the voltage falls below a set value. An integration-type circuit gives an output proportional to the number of pulses and operates a relay if the voltage equals that set by a reference circuit. If the phases are out of step, a detector circuit causes a transistor to conduct, thus discharging the capacitor and preventing the relay from operating.

Title: Speed fluctuation compensation in vehicle roller tester - using summing amplifier circuit to compensate tachometer output signals and two rollers with revolution counters
Inventor: POHL DIETER DR
IPC: G01M17/02
Filed: 1975-10-18
Abstract: The compensation system for motor vehicle roller testing equipment provides correction for errors due to oscillating movement between the vehicle wheel and the measuring rollers. The test apparatus comprises two rollers. The load roller (11) and the support roller (12) are fitted with revolution counters (16,17). The load roller also has a flywheel (15) which gives it a greater moment of inertia. The oscillating variations in speed of rotation of the rollers differ in amplitude and phase. Compensation is effected by adding the amplitudes of the two values. An operational amplifier connected as a summing amplifier is used. The ratio of the two input resistors is equal to the ratio of the inertia moment ratio of the two rollers.

Title: Vertical displacement of oil from underground formations - by simultaneous top injection of light and heavy hydrocarbon solvents
Inventor: BRADEN JUN WILLIAM BERNARD
IPC: E21B43/18
Filed: 1975-11-12
Abstract: Extn. of oil from underground formations contg. a liq. oil phase satd with gas, by simultaneous and separate injection into the top of the formation of (A) a light hydrocarbon solvent, and (B) a heavier hydrocarbon solvent, until a mixed slug is formed with direct or limited miscibility with the oil phase under the prevailing temp. and pressure.
