Title: Woven fabric having warp threads joined by - a multi-component weft
IPC: D04B39/00
Filed: 1968-12-12
Abstract: The warp threads are joined by a multi-component weft consisting of a system of loops arranged side by side and overlapping each other. The single threads are joined simultaneously to at least two warp threads, thus permitting fabrics other than in strip form to be woven. Specifically the consecutive loops form sections. The first single thread passes as a loop interweave into the following loop of the following multi-component weft of one and the same section. The second single thread of the same loop passes similarly into the preceding loop of one and the same section. Two neighbouring sections are always joined by interlacing in the form of interweavings of loops of one section around the hooking-up element of the neighbouring section. The loop stitches of each section are joined on one side.

Patent DE-2064401-B2 (DE)
Title: DC motor speed controller - has differential amplifier in feedback loop and armature forming part of bridge circuit
IPC: H02P7/288
Filed: 1970-12-30
Abstract: The motor armature (1) forms one arm of a balanced bridge. A power transistor (17) controls the load. Diagonal points (B, D) of the bridge are connected to the differential amplifier (5, 6). The speed setting potentiometer (9) is bridged by a zener diode (11). With the circuit closed (13) the motor runs up to a speed determined by the potentiometer setting (9). If the speed tends to increase the armature emf increase causes the differential amplifier to tend to turn off. This reduces the power transistor drive which reduces the voltage applied to the motor. If the motor load increases and the resistance drop in the armature rises the differential amplifier turns more on and more voltage is applied to the motor.

Title: Continuous strip cutter speed control - uses pinion driven tachogenerator providing carriage velocity, with cutter triggered by amplifier when cutter and material speeds equal
IPC: B23D36/00
Filed: 1972-06-21
Abstract: The continuous cutting of strip materials into fixed lengths is achieved by moving the cutter at the same speed as the materials at the instant of cutting. The cutter is mounted on a carriage that is moved by a rack and pinion driven by a servo valve controlled hydraulic motor. The command velocity for the cutter carriage is provided by the output of a tachogenerator driven from the strip. The pinion drives a tachogenerator providing a measure of actual cutter speed and a regulator provides a correcting signal for the servo-valve. An amplifier generates an output when the speeds correspond to trigger the cutter actuation. A position transducer is used to detect the cut edge of the strip.

Abstract: PURPOSE:To cause a creep-preventive control apparatus to have a function to make fail-safe in the case where there is a probability that back-movement may occur, during a creep-preventive control operation. CONSTITUTION:In a creep-preventive control apparatus adapted to prevent creep phenomenon by disconnection of a forward clutch when specified conditions are established, decision is made on whether or not a speed change stage where a brake for Hill holding is engaged can be achieved (steps 501 to 507). If the decisions that such achievement is impossible are sequentially made a specified number of times (steps 509 and 510), a flag F1 of 'fail' is caused to stand (step 511) to interrupt disconnection of the forward clutch.
Patent JP-S5413304-B2 (JP)
IPC: H04L17/16
Filed: 1974-05-29
Abstract: A detector for detecting predetermined digital words within a train of signals wherein the digits in the words each have a predetermined time period. The detector continuously samples the train of signals coupled thereto. Samplings are taken a number of times during the interval of a digit time period, and a digital signal corresponding to the sampled signal for each sample taken is stored in a multi-stage storage register. Comparison circuitry compares the digital signals in the storage register with a first predetermined word in a memory circuit. If there is a correlation, the comparison circuit counts for a time period long enough to sample the train of signals and store a new series of signals corresponding to a second digital word. The comparison circuit compares these second digital signals with a second word in the memory circuit. A correlation between theset two words produces a detection signal.
