Abstract: ABSTRACT OF THE DISCLOSURE         A process and apparatus are described for the treatment of gaseous effluents containing noxious gases and steam from the sufluric acid digestion of titaniferous materials.  In the stages of the digestion where the gaseous effluents are given off, these are passed upwardly through a condenser pipe and through a hollow cylindrical zone of swirling liquid within the pipe forming a descending condenser film, whereby the steam is at least partly condensed. According to the novel feature, during the entire duration of the digestion an alkaline liquid is sprayed into a stream of gaseous effluents passing through the hollow cylindrical zone to remove noxious gases from said effluents and the alkaline liquid which has contacted the gaseous effluents from each stage of the digestion is collected, with the alkaline liquids collected from the stages of digestion producing relatively small amount of gaseous effluents being at least partly recycled to the alkaline liquid sprays.

Abstract: ABSTRACT OF THE DISCLOSURE In an operating cycle for a pneumatic operated ramming tool with a compressed-air loaded working piston disposed reciprocally therein, at the beginning of a working stroke the working piston is initially set in motion under the action of small amounts of compressed air until its top moves into a region of stored compressed air which then flows past the sides of the working piston and fully engages the working face thereof for performance of a working stroke.  The working cylinder comprises a pressure portion and a guide portion, the upper end of the pressure portion being in communication with the compressed air storage space via a closable control port.  Within the pressure portion there is an annular gap between the cylinder wall and the piston and at the bottom end of the pressure portion is a plurality of connecting apertures to the compressed air storage space.  The working piston extends into the cylinder pressure portion at its top end carrying two seal rings, and protrudes into the cylinder guide portion at its bottom end carry-ing one seal ring.  The lower one of the two seals fitted at the piston top end serves as return stroke seal due to its variable diameter.

Abstract: A PROCEDURE FOR TIGHTENING TAPE WRAPS   ON A SPINDLE                           Abstract During a search operation in a rotating magnetic head tape transport, the tape is transported from a supply spool via guides and a vacuum column past the rotating head read/write station to a take-up spool.  As the tape is wound onto the take-up spool in layer-by-layer convolutions, air is entrapped between the layers.  The entrapped air forms a layer of air film and as a result the tape is loosely wound on the take-up spool.  A "Hard Step" voltage is generated and is applied to the capstan motor at the end of the search operation to tighten any loose wraps caused by the air entrapment during the search.

Abstract: ABSTRACT:         A temperature supervising system comprising a temperature sensor which is designed to sense the temperature of the supervised component and to supply a signal representing the said temperature, which sig-nal is compared with a reference signal to produce an alarm or to interrupt the connection of the component to a supply source when the difference between the signal indicating the temperature and the reference signal exceeds a given value, for example zero. The reference signal is generated by a function generator which supplies a signal varying with time, which sig-nal, in a period immediately after the instant the component is connected to its current source, increases according to any desired function, for example step-wise or linearly, from a low initial value to a higher output value.

Abstract: ABSTRACT           A controlled space is maintained at a desired set point temperature by adjusting the evaporator boiling pressure in a refrigeration system, thereby controlling the evaporator capacity (namely, the amount of cooling imparted to the air supplied to the space) which is inversely proportional to the evaporator boiling pressure.  When the space temperature tends to vary from the desired set point due, for example, to a changing heat load, the control system automatically changes the refrigerant flow through the evaporator to establish the evaporator boiling pressure (and hence the boiling temperature) at the control point required to cool the air sufficiently to maintain the controlled space at the desired temperature.  More specifically, in response to a space temperature increase, the flow rate of the refrigerant increases to decrease the evaporator boiling pressure; and in response to a drop below the set point, the refrigerant flow decreases to increase the evaporator boiling pressure. Such control of the flow rate, and consequently the evaporator boiling pressure, is achieved by varying the displacement of a controlled displacement compressor included in the refrigeration system.  When the heat load on the evaporator is constant, the refrigerant flow is automatically controlled in order to hold the evaporator boiling pressure fixed at the required control point.

Abstract: RIBBON FEED MECHANISM                   ABSTRACT OF THE DISCLOSURE      A ribbon feed mechanism for typewriters operable to incremen-tally feed a ribbon with a dual segment continuous motion ribbon feed.  The ribbon is advanced an initial segment by a power actuated linkage and advanced a final segment by a spring urged arm acting on a multi-toothed cam.  The initial segment feed occurs when a bellcrank is pivoted, and through a linkage, urges a ribbon metering shaft to rotate which, in turn, feeds the ribbon.          Simultaneously, a spring biased cam follower is gradually displaced by the multi-toothed cam which is supported on the metering shaft.          The final segment feed occurs as the spring biased cam follower is rapidly displaced down a cam surface of a tooth on the multi-toothed cam.

Abstract: ABSTRACT OF DISCLOSURE           A continuous process for acid gas removal from process gas streams by contact with an aqueous alkanolamine solution such as MEA wherein the temperature of the MEA solution is controlled by placing an intercooler at the lower end of the absorption column such that the temperature of the down-coming MEA solution is cooled to allow increased mole loading of acid gas in the solution, but is not so cooled that the mass transfer rate of the acid gas from the process gas to the MEA solution is slowed to an unacceptable level.          The lower temperature highly loaded MEA solution is then passed to a heat exchanger-flash-heat exchanger arrangement where the temperature is increased to provide satisfactory flash efficiency and then heated again prior to introduction into the stripper to reduce the sensible heat duty in the stripper.  The combination of optimally positioned intercooler and flash together with the temperature ranges recited permit the obtainment of a net energy demand lower than can be expected from the addition of the intercooler effect and the flash effect.
