Title: Conditioning agent for aquarium water - comprising cellulose ether and ethylene di:amine tetra:acetic acid
IPC: A01K61/00
Filed: 1983-04-08
Abstract: Aquarium water for live fish is conditioned by dissolving a cellulose ether and EDTA in the water in a ratio of 1.5-3:1, esp. 2:1. The cellulose ether and EDTA are pref. combined together before being dissolved in the water. A typical dosage for salt water aquaria is 5 ml. per litre of aquarium water of a soln. of 6 g. methylcellulose and 3 g. EDTA-Na in 1 litre water. A typical dosage for fresh water aquaria is 5 ml. per litre aquarium water of a soln. made by dissolving 10 g. methyl cellulose in 500 ml. water and adding 500 ml. 1 wt.% Na-EDTA soln. The EDTA chelates harmful metal ions and the cellulose ether replaces the mucous covering on the skin of the fish which may be lost e.g. when the fish is transported or transferred from one pool to another, e.g. when restocking pools or tanks. Such loss of mucous membrane renders the fish liable to disease and has previously been the cause of losses when transferring fish.

Title: Recording system for colour video signal - processes colour components alternately line by line using sum and difference techniques
IPC: H04N9/81
Filed: 1986-07-04
Abstract: The PAL standard video input signal (1) is fed to a low pass filter (2) and also to a delay circuit (5). The filter (2) extracts the brightness and synchronisation signals from the chrominance signal. The l.f. signal is then inverted (3) and summed (4) with the delayed signal. The summer output and the delayed signal are then fed to a phase-locked loop circuit (6-8) which regenerates the colour carrier signal. The synchronisation signals are compressed and added (9 to 15) to the colour signal before being fed to the transmission or recording system (16). The output of the transmission system (16) is fed to a circuit (17 to 29) with similar components which regenerates the original PAL standard signal (29).

Patent PT-97516-A (PT)
Inventor: GEIRHOS JOSEF
IPC: D02G3/04
Filed: 1991-04-29
Abstract: An entangled multifilament yarn made of high-modulus individual filaments, such as, for example, aramide, carbon or glass, and a method of making this yarn are described. Customary air entangling is virtually unusable in the case of high-modulus yarns, since, owing to their brittleness, they have a tendency to break, which leads in particular to a substantial decrease in the tenacity. The invention proposes to carry out the entangling at elevated temperature, either by preheating the yarn or by heating the entangling air. Surprisingly, it has been shown that this substantially avoids a lowering of the tenacity at relatively low entanglement spacings and in some cases even makes it possible to increase the tenacity. The multifilament yarn made by this process is distinguished in particular by a small number of breaks of the individual filaments. The invention is also applicable to so-called comingled yarns in which only a portion of the yarn consists of high-modulus filaments and the other portion of thermoplastic filaments.

Title: Windscreen wiper with pump nozzles located on its handle
Inventor: FIGELJ ALEKSANDER
IPC: B60S1/04
Filed: 1999-09-28
Abstract: The windscreen wiper (1) with pump nozzles (3) located on the handle (2) of the windscreen wiper ensures unchanged visibility when using cleansers, while the cleaning liquid is applied to the whole surface of the glass, even in the most extreme areas. On the windscreen wiper (1) handle (2) there are two pump nozzles (3). Each of them is located on one side of the windscreen wiper looking into its own direction (I). The pump nozzles hava three openings, which help to apply the cleanser in three directions: the upper end of the wiper, the centre of the wiper and the lower end of the wiper. This way a thin layer of cleanser along the whole length of the wiper is applied. The pump nozzles (3) are connected to tubes (5) by an electronic valve, which is controlled by an electronic control circuit. During the cleaning process the valve supplies the cleanser to the pump nozzles (3) which has the wiper (1) moving to it. When the direction of the wiper (1) changes, the valve switches the cleanser supply to the other spraying nozzle (3). Since the cleanser is continuously removed from the glass, it does not reduce the visibility in any way.
