Patent CH-561209-A5 (CH)
Title: Antiviral 2-(alpha hydroxy)benzyl imidazo pyridines - prepd from diaminopyridine and mandelic or phenylacetic acid
IPC: C07D471/04
Filed: 1972-02-28
Abstract: New cpds. of formula (I) are prepd. by reacting cpds. (II) with acids (III) (or their reactive derivs.) in an inert high-boiling solvent: (one of X and Y is N, the other is CH; R1 = H, Cl, Br, F or 1-4C alkyl; R2 = H or 1-4C alkyl, but when X = N, R2 must be H and when Y = N, R1 and R2 are not both H; R3 = H or OH). (I) and their salts are antivirals of low toxicity; thus in the plaque reduction test they inhibit growth of various viruses at 20-100 gemma/ml. They may be formulated as capsules contg. suspensions with 5-30% (I). Solvents are suitably chlorinated hydrocarbons, e.g. chlorobenzene and reaction is effected at mixt. b. pt. Derivates of (III) are esters, amides, amidines or anhydrides. Pref. alkyl gps. for R1 and R2 are methyl.

Title: Centrifugal pump with flow deflecting rim - suitable for central heating plant, cavitation noise is almost eliminated
IPC: F04D29/66
Filed: 1973-03-23
Abstract: At the circumference of the pump rotor (9) or on the pump housing surrounding the rotor, a rim (11) is provided which deflects the flow of fluid axially. The transfer of velocity-head to pressure-head in the pump is achieved within the pump rotor and during the flow past the deflecting rim.

Patent CH-643777-A5 (CH)
Inventor: NEUENSCHWANDER GERHARDT
IPC: B30B11/26
Filed: 1982-10-11
Abstract: In a briquette press, the press mantel (10) surrounding the briquettes (7) to be ejected has a configuration preventing the ejection resistance from exceeding a predetermined value so as to obtain a constant hardness of the briquette (7) even when the latter is made from different waste wooden materials and so as to maintain at a low level the required motor power. To this effect, the press mantel (10) is divided in the longitudinal direction. The upper half of the envelope (10b) may pivot upwardly about a hinge (15) as soon as a stop bolt (16) acting on the outer end of said envelope half (10b) withdraws following an overpressure of the compression piston (13).

Patent CH-642864-A5 (CH)
Title: Filter candle for precoat filters
Inventor: STRUB FRITZ
IPC: B01D29/46
Filed: 1982-11-03
Abstract: In the known filter candles for precoat filters, which have a central profiled rod and a multiplicity of annular discs which are threaded onto the latter and are provided with cams to form gaps between respectively adjacent annular discs, the adjacent annular discs being braced against one another by said cams, there has hitherto been the problem that, during their operation, damage, especially in the form of bends in the profiled rod and substantial increases in the gap width of individual gaps caused thereby occurred as a consequence of operating or handling faults made by insufficiently qualified operating staff. These faults then resulted in an impairment of the filtration effect. In the present filter candle, the danger of such damage is substantially reduced by means (4, 6) for arranging the annular discs (2) in such a way that, for each individual annular disc (2), the supporting areas of the cams (3) of said annular disc (2) at least approximately completely coincide with the supporting areas of the cams (3) of the adjacent annular discs (2) viewed in the axial direction of the profiled rod (1). Preferably, profiled rod (1) and annular discs (2) can be provided with means (4, 6) which mutually engage to fix their angular position relative to one another. <IMAGE>

Patent CH-630153-A5 (CH)
Title: Deflection adjustment roll
Inventor: LEHMANN ROLF
IPC: F16C13/00
Filed: 1978-07-12
Abstract: The deflection adjustment roll has a fixed carrier and a tubular roll shell which can be rotated about the latter and is supported on hydrostatic contact-pressure elements. A pump (24) with its drive motor (25) is attached directly to one end of the carrier for the purpose of delivering the hydraulic fluid. This arrangement of the pump (24) makes possible a short reaction time in the event of pressure changes. The motor is provided with a controller (32), to which the measurement signal of a pressure sensor (30) arranged at the outlet of the pump is fed. It is also possible for a plurality of pumps (24) with their motors (25) to be attached to a flat end face (23) of the carrier (1). <IMAGE>

Title: Device for forming the image of the discharge of an excitation source in a substance emitting laser radiation
Inventor: MACK MICHAEL E
IPC: H01S3/091
Filed: 1976-07-21
Abstract: In order to obtain a high efficiency of laser radiation with limited heating up as the conditions of power and of frequency of repetition increase, the device includes a channel (12) for a substance emitting laser radiation while circulating. This channel is delimited by two walls (14, 16) having windows (18, 20) in the form of lenses. An excitation source, preferably an illuminator lamp (22, 24) consisting of an envelope (26, 28) surrounding a region of plasma (30, 32), is opposite the curved face of each window. This source is partially surrounded by a reflector (34, 36). The radiation from the illuminator lamps (22, 24) is directed by the reflectors (34, 36) through the windows in such a way that it is focussed in a region (42) lying entirely within the emitting substance. The device is used for isotope separation and enrichment. <IMAGE>
Patent CH-623518-A5 (CH)
Title: Continuous strip of tearable laminar material for the automatic printing of bills, certificates and the like, convertible into sealed envelopes
Inventor: CONSIGLIO LUCIANO
IPC: B42D15/08
Filed: 1977-08-02
Abstract: The strip of paper or card is divisible along the tear lines (3) into segments which can then be folded and stuck down to form an envelope which is sealed around all four sides but can be opened without tearing. Each segment has a transverse line (5) which divides the segment into two parts of unequal height (h+d and h+2d) and along which the first fold is formed. Longitudinal slits (7) are cut down both sides of that part of each segment whose height is h+d. On one of the sides of the strip adjacent to each transverse line (5) which separates the two said parts of each segment is a band (E) of a self-adhesive means applied to the shorter part (h+d) of said segment, while on the opposite side of the strip on the longer part (h+2d) of each segment and adjacent to the tear line (3) is a self-adhesive band (D) of the same height. Longitudinal self-adhesive bands (D') are provided on the same opposite face on the longer part of each segment in continuation of the two series of longitudinal slits (7). Each segment has a second tear line (6) along the inner edge of the band (E) opposite the edge coinciding with the transverse line (5). To produce the envelope, a first fold is made to bring the shorter side of height h+d down upon the longer side h+2d, and then a second fold at right angles to the first is made along the axial line (4); in this way the self-adhesive bands are brought together and the envelope can be sealed around all four sides. <IMAGE>

Pref. the tear tape is of the same material as the wrapper but of thicker gauge.

Title: Herbicide for controlling aquatic weeds
Inventor: MEYERS MARION DOUGLAS
IPC: A01N59/20
Filed: 1975-02-07
Abstract: New agents for combatting aquatic weeds contain as active component a complex of (a) a Cu (II) cpd. (e.g. CuSO4.5H2O and (b) an amine of formula R1 (NR2-R5)nNR3R4 (I) (where R1-4 are each H or 1-3C alkyl; R5 is opt. branched 2-6C alkylene; and n is 1-5) or an aminoalkylene-alkanolamine (II) in which the alkylene chain is 2-5C and the alkanol residue is 2-5C.The complexes are useful for combatting various aquatic weeds, including Naiadaceae, Vallisneriae, Hydrillae, Myriphyllum verticillatum, water hyacinth, and Egeria, esp. Hydrilla verticillata and Egeria densa.  They have low fish toxicity, low corrosiveness, and no tendency to deposit Cu metal. The compexes are stable even at pH 6-12, and are therefore suitable for use in alkaline waters.In an example a 1:2 complex of CuSO4.5H2O with Ethylenediamine was prepd. by the exothermic reaction of crystalline CuSO4.5H2O (1 mol) with 91-93% ethylene-diamine (2 mol.). The soln. obtd. was diluted with water to a Cu content of 7%, to give a solution of pH 11.5.
