Title: Process for the production of colour photographic images
IPC: G03C7/32
Filed: 1965-07-12
Abstract: The invention comprises pyrazolone compounds of the formula <FORM:1118745/C2/1> wherein R is alkyl, amino, acylamino or phenylureido and R1 is alkyl, aralkyl or sulphoalkyl, with the proviso that when R1 is alkyl R is alkyl, amino or phenylureido except that when R1 is hexadecyl R can be hemisuccinylamino. In specified compounds, R is methyl, amino, myristoylamino, hemisuccinylamino, 4-nitro-benzoylamino or 31-[(311-stearoylamino-511-carboxy) anilidosulphonyl]-benzoylamino, and R1 is methyl, hexadecyl, benzyl or 4-sulphobutyl. The compounds are made by reacting appropriately substituted phenylhydrazines with ethyl acetoacetate or ethyl beta-imino-beta-ethoxy-propionate to form the pyrazolone, or, in the case of acylamino compounds, by acylation of an amino-pyrazolone.  The compounds are photographic colour couplers (see Division G2).  4-Methylsulphonylphenyl hydrazine, 4-benzyl-sulphonylphenyl hydrazine, 4-hexadecylsulphonylphenyl hydrazine and 4-(41-sulphobutylsulphonyl) phenyl hydrazine are made by refluxing hydrazine with 4-methyl sulphonyl-chlorobenzene, 4-benzylsulphonyl-chlorobenzene, 4-hexadecylsulphonyl-chlorobenzene and 4-(41-sulphobutyl-sulphonyl)-chlorobenzene respectively. 4-Benzylsulphonyl-chlorobenzene is made by reacting benzyl chloride with sodium 4-chlorobenzenesulphinate.  4 - Hexadecylsulphonyl - chlorobenzene and 4-(41-sulphobutylsulphonyl)-chlorobenzene are made by oxidizing with hydrogen peroxide in acetic acid, 4-chloro-S-hexadecyl-thiophenol and 4-chloro-S-(4-sulphobutyl)-thiophenol respectively. The latter is prepared by reacting 4-chloro-thiophenol with butanesultone.

Title: Labyrinth lubricant seal for belt conveyor roll
IPC: F16C33/80
Filed: 1976-07-19
Abstract: The embodiment of the invention disclosed is a conveyor roll having a cylindrical shell with integral end caps and axial sleeves extending inwardly from the end caps. The shell, end caps and sleeves are rotatably journalled about the shaft by roller bearings between the sleeves and the shaft. An internal labyrinth is provided in each sleeve between the bearing and the end of the shell, this internal labyrinth including a rotatable collar and a non-rotatable bushing carried respectively by the shell and shaft and having a series of facing cylindrical and annular surfaces providing a labyrinthine passageway of restricted cross-section extending from the bearing means to an annular outlet at the end of the shell. An external labyrinth is provided outside the end cap. This includes first and second annular flanges carried respectively by the shaft and shell and axially spaced from the annular outlet and from one another. These two flanges provide inner and outer radial passages. The outer radial passage has radial and axial dimension exceeding those of the inner radial passage whereby centrifugal force acting on a radial column of lubricant in the outer radial passage opposes leakage from the shell.

[Also in Group XVII] Apparatus for hermetically sealing metal cans comprises an intermittently-driven turntable 1 on which are mounted a plurality of axiallymovable open-topped containers 8 for cans 10, each having a lid 17 loosely in position thereon, a pressure chamber 13 containing electrowelding sealing means being located over the path of the containers 8 and having an opening 14 in the base thereof to permit the entry of the can to be sealed, the containers being axially moved in turn by means of a hydraulic ram 12 so that the rim 16 of the container contacts the marginal portion of the opening 14 and makes a fluid-tight seal therewith whereupon gas under pressure is forced into the chamber 13. Although the motion of the container has been arrested, the can continues to move upwardly until the can lid engages a stationary power-driven rotatable electrode 21 and is forced home inside the can. A freely rotatable electrode 19 is now moved automatically into contact with the rim of the can and the electrode circuit completed. The electrode 21 is then rotated and welds the lid to the can after which the electrode circuit is broken and the electrode 19 withdrawn from the can rim. At this point, the gas pressure supply is cut off and the ram 12 retracted. Each container is supported on the turntable by means of a rod 5, flange 6, and compression spring 7, and each can is supported in its container by means of a disc 9 provided at the end of a rod 5. The cans may, alternatively, be sealed under vacuum.

Drawings to Specification. [Class 98 (ii)] Layers sensitized with naphthalene diazonium compounds and having an acidity or alkalinity such that no colouring matter is formed during exposure, are exposed under an original and self-development effected by the action of water only is allowed to take place. The self-development may be accelerated by heating or by an increase in the moisture content of the layer. A white background is obtained if the layer has a degree of moisture less than 1 per cent during the exposure, this being attained by drying over phosphorus pentoxide or in a stream of dry gas. In an example, the paper is soaked in a solution of diazo-2-hydroxy - naphthalene-4-sulpho-acid and anhydrous soda and dried in air. After exposure the paper is allowed to develop in the dark or developed by smoothing it under a moistened cloth at 100‹ C. The paper may be intensely dried before use. The soda may be replaced by sodium borate, sodium phosphate or sodium selenite. To obtain a negative from a positive, a short exposure may be given and, after self-development in the exposed parts has taken place, a second exposure which causes complete decomposition in the unexposed parts. Specification 391,970 is referred to.

[Also in Group XL (c)] In an electromagnetic relay circuit a relay R is energized through the emitter-collector circuit of a transistor T which is caused to conduct by a voltage applied to its base, the latter being connected to the junction between a zener diode Z<SP>1</SP> and resistor r<SP>3</SP>; the diode being connected to a tapping point of a potential divider r<SP>1</SP>, r<SP>2</SP> across the supply voltage and through the resistor r<SP>3</SP> to the positive supply line. When the supply voltage increases, the reverse voltage across the diode s1 increases until the critical voltage of the latter is reached and the diode conducts so that the resulting potential across the resistor r<SP>3</SP> causes the transistor to conduct and the relay to operate. A series dropper resistor r<SP>4</SP> may be used if the supply voltage is in excess of the voltage rating of the components. Additional protection, Fig. 3, may be obtained by providing the relay R with auxiliary contacts C1, C2 and resistor r<SP>5</SP> so that when the relay operates the transistor T is cut out of the circuit and the supply to the zener diode Z<SP>1</SP> is interrupted. Alternatively, a further zener diode, Fig. 4 (not shown), may be connected across part of the resistor r<SP>1</SP> so as to stabilize the supply to the first diode Z<SP>1</SP>. A rectifier or capacitor may be connected across the relay operating coil.
