Title: Correction method for data signal modulated on carrier - is for signal distorted by linearly distorting transmission medium
IPC: H04L27/01
Filed: 1973-07-12
Abstract: The received distorted signal r(t) is subjected to a transformation during which a quadrature signal r(t) of the original signal is produced; and two signals y(t) and y(t) are obtained by filtering from the above two signals. The signals are subjected to convolution operations by two filter transmission characteristics and the two signals values y(t) and y(t) are obtained. The original received signal r(t) is applied to two filters with transmission characteristics h1(t) and h2(t) while the quadrature signal r(t) is applied to two further filters with transmission characteristics h2(t) and h1(t). The output signals from the first and third filters are added to produce the first of the two signals (y(t)), and from the second and fourth filter to produce the second signal ( y(t)).

Title: Water and effluent purificn. plant - with inclined sedimentation cylinder working under press.(SF-31.7.75)
Inventor: PERLINA ANNA MIKHAILOVNA
IPC: C02F1/52
Filed: 1974-06-10
Abstract: Water purificn. plant for the removal of suspended and colloidal particles can be used for the treatment of town and industrial wastes and other polluted waters. Water is taken by a pump from an inlet to a sedimentation tank with a conical lower zone, by a pipe system. Coagulant and chlorinated reagent from prepn. tanks are introduced into the water in measured quantities through two pipes. The water then passes up through a conical chamber where flocs are formed by the physicochemical interaction between the coagulant and the impurities in the water. The cone of the chamber has an angle of 30-60 degrees, to ensure the progressive redn. in the rate of flow as the flocs separate. The water reaches a cylindrical portion in which, under the action of gravity, the solids ppte. rapidly on the surfaces of tubes and slide down to reach the conical portion. The water, freed from most of the impurities, passes through a pipe onto a bed of granular filter material; its residual press. from the pump carries it to the top of a water-tower from where it is piped to the customer. The plant is conc. in a small area; it has a high throughput and is both simple and practical in operation. To remove the impurities retained in the filter and in the conical compartment, the tap is opened and purified water, from washing compartment, is passed back through pipe and out by the drain pipe. The tap is closed and the purificn. process starts afresh.

Title: Shuttle-less loom has weft picker driven by drive mechanism - via crank arm which drives a pivoted toothed segment
IPC: D03D47/00
Filed: 1974-07-29
Abstract: A shuttle-less loom includes a guide track for a weft picker mounted pref. on a belt extending between the toothed wheels, the belt being driven by a drive mechanism which is independent of the rest of the loom but connected to it. The drive mechanism drives a shaft to reciprocate and the shaft is connected via a lever to one end of a crank arm, the other end of which is pivotally connected to a pivoted toothed segment so that the toothed segment is pivotally reciprocated. The pivotal connection of the crank arm on the toothed segment is such that the crank arm moves in a plane essentially parallel to the pivot axis of the toothed segment so that movement of the weft picker is unaffected by movement of the guide track. The drive mechanism includes a cam drive arrangement and the motion of the mechanism transmitting drive from the drive mechanism to the weft pickers allows large diameter cams to be used, thereby reducing wear.

Title: Hand towel ring attached to wall fastening member - is axially secured in sleeves to remain in slightly extended position
Inventor: HELLER JOACHIM
IPC: A47K10/10
Filed: 1975-06-05
Abstract: The hand towel holder comprises a wall fastening member with plastic sleeves inserted in bores in opposite sidewalls where they are secured against rotation by suitable means such as ribs. The ends of the towel rings are designed to fit into coaxial bores in the sleeves and so that the rings can be axially secured the bores can be fitted with a constriction. The sleeves are designed to be selectively deformed and for this purpose a threaded pin is mounted at the back of the wall fastening member so that by selectively tightening up the pin the ease of movement of the ring can be adjusted. The towel ring can thereby be prevented from automatically falling back against the wall but can remain slightly extended thereby allowing a better airing of the towel.
