Title: Switching unit for electrically operated extraction hood - has pivotal and axially shiftable actuating lever between two parallel plates
Inventor: NEWBOROUGH LEONARD
IPC: H01H25/00
Filed: 1977-02-24
Abstract: The extraction hood has an illumination system and a blower which can be driven at variable speed. Between two parallel plates is pivotally mounted an axially shiftable actuating lever (8). Between the plates are mounted two commercial pressure switches (12, 14) whose push-buttons point in the direction of the actuating lever, on the opposite sides of which the switches are mounted. A third commercial pressure switch (16) has its push-button aligned with the axis of the actuating lever. Its pressure surface faces the actuating lever. The third switch pivots together with the lever, but is stationary in relation to its axial direction. The lever is preferably mounted in a plastics bearing whose width corresponds to the inside space between the plates.

Title: Double-pile weaving tension control - measures pile yarn tension when loom stops for comparison with warp tension for correction
Inventor: MAASSEN HEINZ
IPC: D03D49/04
Filed: 1977-04-13
Abstract: In weaving a double pile fabric, the piple yarn tension is measured when the weaving operation is suspended, and compared with the pre-set tension value for the warps. Any variation from the norm is corrected, and the pile yarn tension brought to the required value. Pref. when the loom stops, the warp tension is also measured and this value is used as a reference to correct any variation in the pile yarn tension, to give the mean tension for both warps and piles when weaving is resumed. The operating warp and pile tensions are determined while the loom is operating normally, to obtain the reference values, and to calculate the required start tension for the pile yarns when weaving resumes to settle down to the operating tension rating. The process ensures that there is a stable relationship between the tension of the warps and the pile yarns, even if weaving is interrupted, so that there are few pile yarn breakages and the appearance of the woven pile fabric is not affected by a stoppage.

Title: Waste gas purificn. system - by injecting reactive liquid at pressure and temp. ensuring instant atomisation
Inventor: TAUBERT GUENTER DIPL ING
IPC: B01D53/34
Filed: 1977-06-23
Abstract: Waste gases, e.g. flue gases from boilers or incinerators, are purified by injecting a liquid contg. substances which react with the contaminants, are dried and collected in the dry state. The liquid is heated to a temp. above the b.pt. at the gas pressure and its static pressure before injection is kept to a pressure above the boiling pressure of the hot liquid. The liquid is thus instantly atomised into extremely fine droplets. The higher reaction density because of the larger specific area results in smaller apparatus which costs less. The gas can be purified at a lower temperature and the efficiency of the electrofilters is improved. Incrustations of downstream appts. and pipes are eliminated.
Patent DE-2732425-A1 (DE)
Title: Stereophonic headphone with transducers in headband - has tube to provide acoustic coupling between left and right sound chambers
Inventor: HEHEMANN GUENTER
IPC: H04R5/033
Filed: 1977-07-18
Abstract: Stereophonic headphones have a pair of transducers (2, 3) mounted on a headband (1). Ear cushions (6, 7) form a sealed sound chamber (9, 10) with the transducer diaphragms (4, 5). A tube (8) interconnects the two sound chambers and has an adjustable constriction (11) by means of which it can successively and gradually be closed off. Coupling tubes (18) permit the longitudinal and rotational adjustment of the position of the earpieces. The interconnecting tube permits acoustic mixing of the sound from the two channels to obtain a more realistic effect. A double interconnecting tube may be employed as an alternative. In this case, one tube will be fitted with helium. Since the velocity of sound in this gas is greater than in air, the two tubes will have different time delays.

Title: Circuit identifying different AF test signals in telephone exchange - measures signal and pause durations and compares them with values held in store
Inventor: WISSMANN HORST
IPC: H04M3/24
Filed: 1977-08-12
Abstract: The circuit indentifies different audible characters transmitted to a subscriber station for test purposes. The a.f. signal is applied through a Schmitt trigger (ST) to an evaluation circuit (D), at whose outputs (T, P) signals appear corresponding to the presence of the signal proper or of its pauses. The durations of the signal and pause are measured by a counter (Z). Each change from signal to pause starts a high clock frequency interrogation of a store (Sp), whose individual contents corresponds to counter (Z) readings for the signal and pause periods of the a.f. signal. These store contents are compared with the corresponding counter (Z) readings at the instant of level change. The result is applied to a logic evaluation circuit (V) in which individual comparison results are allocated to corresponding a.f. signals. In the case of coincidence the comparator outputs are applied to a corresponding display circuit (AUs).

Title: Ferro-resistant, voltage regulating transformer - keeps flux variations in two cores continuously out of phase to maintain constant level
Inventor: WROBLEWSKI THEODORE
IPC: H01F38/02
Filed: 1978-03-07
Abstract: The transformer has a primary winding formed about a portion of each leg in each of two spaced, juxtaposed cores. A regulated output voltage is produced at a resonant circuit formed by a capacitor and a secondary winding around another leg of the first core. The flux variations in the two cores are continuously out of phase with each other. As the primary voltage changes the magnitude of the total flux in the system, the flux in the second core can vary in magnitude and phase thereby to maintain the flux in the first core at a constant level. Thus, the output voltage at the resonant circuit is substantially constant.
