Abstract: IMPACT CRUSHER WITH RETRACTABLE                  AND TILTABLE FEED CHUTE                   ABSTRACT OF THE DISCLOSURE         An impact crusher is disclosed having a rotor carrying hammers arranged to strike and throw material against target members, and a material feed assembly.  The feed assembly includes a downwardly inclined chute having depending cam followers which ride upon a cam surface having a horizontal portion and a downwardly curved portion at the end of the horizontal portion remote from the rotor.  An actuating device is connected to the chute to move the chute and cam followers along the cam surface and down the curved portion thereof.          Thus when a large rock bridges the space between the feed chute and the target members, and fails to drop into the range of the hammers, the chute is simultaneously retracted away from the rock as the upper end is tilted downwardly toward a horizontal position, to lower or drop the rock into the range of the whirling hammers.

Abstract: METHOD AND APPARATUS FOR CONTROLLING BRIGHTNESS   AND ALIGNMENT OF A BEAM OF CHARGED PARTICLES     Abstract of the Disclosure A beam of charged particles has its alignment and brightness alter-nately controlled in accordance with the current of the beam. The measurements of the current and any corrections for alignment or brightness are made when the beam is not applied to a target.  In operation the beam is applied to the target for a predetermined period of time.  When the beam is not applied to the target it's positioning on the target is aligned and the brightness of the beam is controlled.  This aligning and controlling occurs during a predetermined period of time between the periods of time when the beam is actually applied to the target.  Apparatus for maintaining the substantially uniform current density of the beam of charge particles is also provided.

Abstract: ABSTRACT        This invention concerns yarn twisting apparatus. The invention envisages an elongate curved mounting within which a flexible tube is rotatably mounted so that the flexible tube has a curved longitudinal axis. On passing a yarn through the rotating tube a twist is imparted to the yarn.  By this means the twist imparted to the yarn is even and without slip, since all parts of the interior surface of the tube are rotating at the same peripheral speed.       In contrast certain prior arrangements require slip to take place between the yarn and the surface imparting the rotation because different parts of the surface are at different distances from the rotary axis.

Abstract: ABSTRACT OF THE DISCLOSURE           A control system for an internal combustion engine provides controlled engine spark timing which is a function of a plurality of individual timing signals.  These indi-vidual signals include a throttle advance signal, a pro-grammed vacuum advance signal, a break-idle advance signal, an engine start advance signal, an engine speed advance signal and a fixed timing signal.  These signals are algebraically summed together to develop a resultant spark timing signal representing desired spark timing.  Indi-vidual signals are derived from transducer circuits which are responsive to various engine operating and/or ambient conditions.  The throttle advance signal is a function of both a throttle position signal and a throttle rate signal and provides increasing advance as the throttle increasingly opens.  It is also attenuated as the temperature of ambient air entering the engine for combustion increases.          The programmed vacuum advance signal programs the vacuum advance in accordance with an accumulation function which is representative of the duration for which the engine has been operating in selected operating modes, namely idle and non-idle.  The break-idle advance signal provides momentary advance when the engine throttle is displaced from the idle position.  The engine start advance signal provides advance for a short interval after the engine has been started.  The engine speed advance signal provides increasing advance as the engine speed increases.  The fixed timing signal provides fixed timing which is used to adjust the basic timing for a given set of engine operat-ing conditions,  The control system is particularly advan-tageous when used in an engine which uses a leaner fuel-air mixture (17-18:1, for example) in comparison to presently used mixtures (15-16:1).  Improvement accrues by way of reduction in exhaust emission products and better fuel economy.

Abstract: ABSTRACT OF THE DISCLOSURE         The present specification discloses a delayed-tack adhesive composition comprising in admixture particles of polymeric material having a soft polymeric core surrounded by a hard polymer shell and a solid modifier capable when melted of dissolving the hard polymeric shell. The specification also discloses a method of preparing a delayed-tack adhesive composition, comprising forming in a liquid a dispersion of particles of soft polymeric material, forming around each of the particles a shell of hard polymeric material, providing in the dispersion particles of a modifier capable when melted of dissolving the hard polymeric material, and removing the liquid at a temperature below the melting point of the modifier.      The hard polymeric shell produces particles which are non-tacky and resistant to blocking when incorporated in the unactivated adhesive composition. On activation the modifier dissolves the shell and may also release the soft core polymer, whereby the advantages which are derived from the use of a soft polymer are obtained.
