Title: Water-fed cleaning brush for vessels
Inventor: KORFGEN HARALD
IPC: B08B9/36
Filed: 1984-08-21
Granted: 1988-05-05
Abstract: A brush for cleaning articles like bottles includes a hollow handle and a brush body connected to the latter and having a plurality of bristles. The brush body accommodates a passage through which the fluid flows and is provided with a plurality of slots radially extending from the passage in one plane. Cooperating with the slots is a deflector which has a rim portion extending beyond the plane of the slots so that the fluid after flowing through the handle and the passage is discharged through the slots and deflected onto the bristles at an acute angle with respect to the center axis of the brush.

Granted: 1989-05-24
Abstract: Adhesive bandages comprising a blister pad and adjacent adhesive-coated areas are prepared from heat-fusible bandage materials, preferably a nonwoven batt material, by applying the pad material to a base material and heatwelding around the perimeter of the pad to totally enclose the interior thereof. The portions of the base material extending from the pad area are compacted under heat and pressure to provide a surface suitable for a coating with adhesive. A medicated gel or other therapeutic material may be included within the confines of the pad area to provide a medicated blister bandage.

Title: Heat storage compositions
Inventor: WILLIAMS THOMAS ALAN
IPC: C09K5/06
Filed: 1984-06-25
Granted: 1989-07-06
Abstract: The stability of heat storage compositions comprising tetrasodium pyrophosphate is increased by raising the pH or the composition to at least 10.6. The increase in pH is preferably achieved by adding sodium hydroxide or more preferably an alkali metal orthosphosphate to the composition. The preferred additive is trisodium orthophosphate, The preferred pyrophosphates are those which comprise less than 1% by weight of tripolyphosphates. These compositions are novel and may conveniently be produced by calcination of a mixture comprising disodium hydrogen orthophosphate and trisodium orthophosphate.

Granted: 1989-08-17
Abstract: A toothed drive belt having inner and outer reinforcing fabric layers (4 and 5). The inner layer (4) has a large mesh size, is highly stretchable, has a fine warp of 30 to 210 d, has a normal weft, and the sum of the cover factors of the warp and weft are not more than 20. The inner layer (4) may have either a flat or a wavy shape within the teeth. The outer layer (5) has a low stretchability and a normal warp and weft. The inner layer (4) which is bonded strongly to the rubber substrate (2) of the belt due to its large mesh size, easily follows the deformations of the teeth. Due to a small-thread size, the amount of PLD is reduced.

Abstract: @ in a helical-scan video tape recorder, when the color framing of a reproduced video signal when a magnetic tape is stopped and of a reference video signal when an activation command signal is sent to control means for controlling a capstan motor do not coincide, the activation state of a magnetic tape of the video tape recorder (VTR) is so controlled that the color framings of both video signals are quickly matched with each other.Thus, the recorder comprises:(a) a rotary magnetic head for scanning the magnetic tape on which tracks, each storing one field of at least video information, are arranged obliquely at equal intervals along the tape to reproduce video signals;(b) a servo circuit for controlling a capstan motor on the basis of a control signal produced for every two fields on the magnetic tape and a reference video signal supplied externally;(c) first means for storing color framing information for the reproduced video signals at a time when the tape is stopped;(d) second means for detecting the number of frames by which the reproduced video signals are to be delayed in order to bring the color framing thereof into phase with the color framing of the reference video signal;(e) third means for comparing color framing information for the reproduced video signals stored in said first means and the reference video signals in response to an activation command signal; and(f) fourth means for activating the capstan motor via the servo circuit in response to the activation command signal and for deactivating the capstan motor via the servo circuit on the basis of the output of the second means, the fourth means being controlled on the basis of the results of the comparison by the third means.

Title: Method and apparatus for the insertion of at least one insert into, preferably, folded printed products
Inventor: HONEGGER WERNER
IPC: B65H39/065
Filed: 1987-01-09
Granted: 1989-06-22
Abstract: The printed products to be provided with inserts or supplements are infed in respective pairs by an infeed conveyor to a processing drum or cell wheel. The cell wheel comprises substantially radially extending compartments which are open at the periphery of the cell wheel. Product feed devices, for example, clamps or grippers are arranged in the compartments for forwardly advancing the printed products located in the compartments. Each compartment is divided into two feed channels by a removable divider or partition wall. These divider or partition walls terminate at a predeterminate spacing from the product feed devices. Each of the two printed products which are conjointly conveyed as a pair are infed into a respective feed channel. The printed products in the feed channels of each compartment are then conjointly advanced and approximately simultaneously opened and are furnished with an insert or supplement. This is possible, in spite of their mutual advancement, since the printed products are separated from one another by a divider or partition wall and thus do not completely repose upon one another.

Abstract: The invention relates to a process for obtaining crystals of intermetallic compounds, in particular isolated monocrystals, by cooling alloys in the molten state. The process involves using an alloy in the molten state which has a composition such that the first phase to crystallize during its solidification corresponds to the compound to be isolated, cooling it slowly by subjecting it to cyclic stirring and thermal cycling without attaining the temperature at which another solid phase appears then abruptly expelling the residual liquid. The process is used for obtaining large monophase primary crystals of compounds which melt congruently or incongruently, in particular compounds having symmetry of order 5 known as "quasi-crystals".

Abstract: A method is described which is suitable for soldering components (B) in optical communications engineering, electronics and micromechanics to metallic substrates (T) and at the same time dispenses with the use of solder preforms, which are exceptionally difficult to manipulate, but without having to resort to soldering agents which contain flux. The conventional use of solder preforms is replaced by the use of a paste (P) which constitutes a mixture of a metal powder (Me) and a binding agent (Bi), the binding agent only being essential for handling the paste and being removed from the paste (P) by a vacuum (V) before the actual soldering process. A method of this type is used in micromechanics, e.g. in order to fasten a planar piezo-head to a nickel foil by soft soldering. <IMAGE>
