In a photographic type-composing machine, comprising means for projecting the images of type-face characters one at a time progressively on to a sensitized surface from a character matrix so that lines of text are composed on the surface in accordance with information previously applied to a control tape, the progressive projection of characters on to the surface is carried out, for at least part of the surface, two or more times, each time using a different character matrix and using only that information on the tape which is appropriate to the matrix being used. A perforated control tape may contain for each character, coordinate information indicating the co-ordinates of the character in the matrix and which matrix is appropriate for those co-ordinates to give the desired character. As shown, Fig. 5, the light path 5 to the sensitized surface may be interrupted by a vane 3 which is pivoted at 4 and movable by a piston 1. This piston is actuable by air from a valve 8 which is manually settable to a number of alternative positions such that when a character read from the tape does not correspond to the matrix being used at that time air is admitted, via appropriate combinations of lines X, Y or Z to actuate piston 1 and block the light path.

Abstract: 871,131. Friction clutches. SCHWITZER CORPORATION. Nov. 13, 1959 [Dec. 19, 1958], No. 38538/59. Class 80 (2). [Also in Group XXIX] In a drive for an engine cooling fan a disc 21 on the driving shaft 10 functions as a friction clutch disc up to a predetermined engine speed, when it is cut out by the effect of centrifugal force, and then operates as the impeller of a fluid slip coupling. As shown, the disc 21 is mounted inside the fan hub 12 which is partially filled with liquid, such as a silicone oil, and the outer portion of the disc is split radially to form a series of fingers 23 which are bent alternately in opposite directions axially, whereby friction elements 24 thereon are resiliently pressed against annular surfaces on the hub to transmit the drive thereto. Due to the offset arrangement of the clutch fingers 23 their natural resilience is overcome by centrifugal force at the predetermined engine speed, so that the elements 24 are disengaged from the hub and disc 21 then operates only in the liquid, the device acting as a slip coupling.

A method of carrying out technical processes (e.g. metallurgical or chemical) by means of an electrical glow discharge in a receptacle with at least two insulating leading-in connections, between which there is a voltage of at least about 100 volts, and connections for the outlet, and supply of gas, is characterized in that in the immediate proximity of at least the surfaces participating in the process a state of gas discharge is produced and maintained in which the electronic current emitted by the surfaces is everywhere more than compensated by the ionic current to the said surfaces, the ionic current density being adjusted to at least 0À1 mA/cm<SP>2</SP>, so that said over-compensation is ensured also at any localized overheated parts of the surfaces and so that a cathode drop is maintained, and a transition into an unstable region of the discharge characteristic and the contraction of the discharge to a burning spot are avoided. Curves are given showing a typical current/voltage characteristic of a glow discharge compared with a characteristic obtainable by the method according to the invention. Further curves show plots of thermal emission against temperature as obtained from the Richardson formula for various chemically pure metals and metal compounds, together with plots which can be used for estimating the maximum possible emission current in the case of workpieces which are not chemically pure, thus giving a value for the discharge current necessary, which value is attained mainly by increasing the gas pressure in the receptacle. In one example a molybdenum pipe is heated by a glow discharge to a temperatue of about 2000‹C. in an atmosphere of hydrogen at a pressure of 9 mm. of mercury. Further results, some obtained using a mixture of nitrogen and hydrogen are tabulated and curves are given showing the inter-relationship between current, voltage and gas pressure, the permissible working limits being indicated.

[Also in Division F2] A lubricator comprises guide means 5 directing an oil mist from an ejector nozzle 3 to an outlet opening in wall 6, the guide means producing a smooth change of direction of the oil mist when in a first position and an abrupt change when in a second position. In Fig. 1 oil is drawn from a sump in container 1 up riser 2 containing filters to nozzle 3 connected to a compressed air source, and oil mist from nozzle opening 8 enters an air space above the sump. With guide member 5 in the first position (Fig. 4) the mist is deflected by the curved wall of a semi-cylindrical channel 12 and passes through channel 12 to the outlet opening.
