Patent DE-2440782-A1 (DE)
Title: Shearing machine adjustment mechanism - with a data store for fabric types with automatic reset on a fabric change
Inventor: VOLLENWEIDER MAX
IPC: D06C13/00
Filed: 1974-08-26
Abstract: Appts. for shearing textile fabrics has a store set with the required value of the shearing gap between the shearing blade and the shearing table. A sensor is provided to register the passage of a seam denoting the change from one grade of fabric to another for a switching circuit to change the value by calling it from the store for adjustment to be made to the shearing gap. The system gives a continuous shearing operation without having to stop the machine when the fabric to be sheared is changed, in order to reset the shearing components.

Title: Bidirectional pressure fluid flow detector - replaces electrical limit switches on electrically controlled hydraulic linear motors
Inventor: KUCHARZYK REINHARD
IPC: G01P13/00
Filed: 1975-06-21
Abstract: A pressure fluid flow detector produces an electrical signal for sequential control machines with automatic operating cycles. A restrictor (15) obstructs the pressure fluid flow in a working connection (B) until the forces produced by the flow exceed those of a fluid and a spring (16) in a chamber (4) on the other side of the restrictor. The restrictor is then pressed back against the spring and allows flow in the working connection with a pressure difference determined by flow restriction and largely independent of the flow rate. The flow medium also enters an annular chamber (29, 37) formed by shoulders on a piston which is pressed by the flow pressure against the spring.

Title: Concrete tendon stressing friction loss reduction - uses pulsating hydraulic oil in cylinder to vibrate stress tendons
Inventor: HILBERT HELMUT
IPC: E04G21/12
Filed: 1975-08-16
Abstract: The process is designed to reduce friction involved in stressing the tendons cast in concrete structures, which can lead to serious friction loss, esp. with stressing in curved rods. The hydraulic oil required for the stressing process is led into the stressing cylinder of the press in pulsating surges, so that the stress member being treated is directly vibrated. Provision may be made for varying the frequency and amplitude of pulsation during the stressing process. Friction loss is significantly reduced, without recourse to any additional devices or procedures in the course of the stressing process.

Title: Heater for highly viscous mediums - uses flow pipe with corrugations in two directions for heating foods
Inventor: SCHEMMEL AUGUST
IPC: F28F1/06

Title: Triple line sequential transmission of recorded TV signal - uses filter stages and delay to provide multiple resets at specific frequencies
Inventor: DICKOPP GERHARD DIPL ING DR
IPC: H04N9/86
Filed: 1976-03-25
Abstract: A triple line sequential transmission system for colour t.v. recordings has multiple reset points at particular frequencies given by (n+1/3) fH. The three colour signals (R, G, B) are sequentially sampled over a selector (15) to provide an input for an adder stage (16) with a subtracted valve provided by a matrix (17) indicating an intensity valve. The signal is processed by a l.p. filter, 0-0.5 mHz (18) and a correction stage (19) that reduces the cross-luminance effect. A l.p. filter (21) generates an intensity signal that is subtracted from the matrix output. A circuit (24) increases signal definition and the output combined with that from a delay stage (36). A final delay stage (28) compares the difference between the l.p. filter delays (18, 21).
