Title: Nozzles
IPC: E04F21/12
Filed: 1971-04-19
Abstract: 1356622 Nozzles for cement guns SPIROLET CORP 19 April 1971 [2 Feb 1970 5 Oct 1970] 20814/71 Heading E1S [Also in Division B2] A nozzle for a cement gun comprises an elongated body of resiliently yieldable material, preferably polyurethane, having a bore therethrough which bore has a helical threaded formation comprising a spiral projection, a spiral groove and means for controlling turbulence in the bore. Figure 5 shows the inlet end of an embodiment of the nozzle in which the wall of the bore is formed with a spiral groove and a spiral projection, the groove and projection being so formed that turbulence of wet cementitious mixture carried along the bore is controlled by, for example, a gradual transition from the projection to the groove on the side of the projection towards the outlet. The inlet end of the nozzle is also formed with an annular recess 60 defining an inner wall portion 62 having an end face 64 lying in a transaxial plane slightly offset axially inwardly from the transaxial plane of the end of the wall 58 of the nozzle body. This recess communicates via passages 74, 82 and 80 between a supply of water through opening 72 and the interior of the nozzle so that cement introduced into the bore of the nozzle is mixed with water to form a wet cementitious mixture. The size of the passages 82 and 80 may be adjusted by threading or unthreading coupling 22 relative to nozzle 20, so that the right amount of water is added to the cement. Alternative embodiments include two-part nozzles, alternative adjustable connections between the water supply and the bore, and alternative methods of making the nozzles are described (Figs. 6-18, not shown).

Abstract: 516,253. Discharge lamps. GENERAL ELECTRIC CO., Ltd. (Patent-Treuhand-Ges. fur Elektrische Gluhlampen). July 19, 1938, No. 21399. Addition to 504,432. [Class 39 (i)] [Also in Group XXXV] As in the parent Specification a high-pressure mercury-vapour electric discharge. lamp is run above a certain wattloss per centimetre of discharge path, so that it has a positive characteristic and may be run directly from the supply or in series with an impedance element which does not absorb more than 10 per cent. of the supply voltage. According to the present invention, the lamp is run at a watt-loss much greater than 30 and is of the kind wherein the ratio of that part of the heat developed in the discharge dissipated otherwise than by radiation is much greater than in street lighting lamps having a discharge column a few centimetres long and an envelope about 2 centimetres in diameter. In such a lamp, Fig. 2, having a quartz discharge envelope 1, tungsten running electrodes 2 and starting electrodes 3 the distances a, b, c, d, e are respectively 32, 16, 8, 8, 22 millimetres. In Fig. 1 (not shown) a lamp has a spherical envelope 40 millimetres diameter. The minimum value of watt-loss per cm. necessary for operating these lamps is stated to be influenced by the length of the discharge path, the nature of the electrodes and their supports, and the diameter of the envelope. Equivalent circuits are referred to and connection of the lamp across the secondary of a strayfield transformer, the primary of which is directly connected to the supply, is mentioned specifically. Means are provided as in the parent for restarting the discharge after zero in each cycle. The lower limiting watt-loss per cm. is said to be greater when the supply is alternating than when the supply is direct.

Abstract: Polyazo dyes capable of being coppered on the fibre or in substance are made by coupling a diazo compound of an aminoazo dye, obtainable by coupling a diazo compound which contains an --OH group and a --COOH group in o-position to each other with a 1-naphthylamine-2-alkylether, with a compound of the formula <FORM:0460378/IV/1> in which Cy is the cyanuric residue, A is a substituted or non-substituted aminonaphthol residue, R is the residue of an amine containing an --OH group in o-position to a --COOH group and X is a halogen atom or any other residue connected with Cy by means of N, O or S.  They dye cotton blue to green shades which when after-coppered undergo only little alteration in shade and are fast to washing and light.  According to an example, the diazotized aminoazo dye 4-amino-1-phenol-2-carboxylic acid --> 1-amino-2-methoxynaphthalene-6-sulphonic acid is coupled in presence of pyridine with the ternary condensation product from cyanuric chloride, J acid, 4-amino-4<1>-oxyazobenzene-3<1>-carboxylic acid and aniline (green); H or K acid may be used instead of J acid.  A table of dyestuff is given in which the following additional components are specified; starting component; 4 - amino - 4<1> - oxyazobenzene-3<1>-carboxylic acid; A, R or X in above formula; 4 - (4<1> -aminobenzoyl) amino - 1 - oxybenzene - 2 - carboxylic acid, 4<1> - amino - 5<1> - methoxy - 2<1>-methyl - 4 - oxyazobenzene - 3 - carboxylic acid, 2 - amino - 5 - naphthol - 7 - carboxylic acid, 4-aminophenol-2-carboxylic acid, aniline.
