Abstract: Abstract of the Disclosure A crystallized sugar product containing a food ingre-dient is prepared by concentrating a sugar syrup at a temperature in the range of about 250°F. to about 300°F. to a solids content of about 90 to 98% by weight, the sugar syrup containing no more than about 20% by weight non-sucrose solids, admixing the concen-trated sugar syrup with a predetermined amount of the food ingredient, subjecting the admixture to impact beating within a crystallization zone until a cry-stallized sugar product made up of aggregates of fondant-size sucrose crystals and the food ingredient is formed, the crystallized sugar product having a moisture content of less than 2.5% by weight, and re-covering the crystallized sugar product from the crystallization zone.  The resulting sugar product is dry, granular, free-flowing, non-caking, and readily dispersible in water.  The resulting sugar product may be either an intermediate food product, such as a gelatin concentrate, or an instant food product, such as an instant chocolate pudding mix, which con-tains all of the dry food ingredients for the final food product.

Abstract: METHOD AND MEANS FOR DISPOSAL OF RADIOACTIVE WASTE.     ABSTRACT OF THE DISCLOSURE          Method and means for solidifying nuclear waste for permanent disposal are disclosed.  A storage container, in the preferred form of a drum or barrel, is charged with a predetermined amount of liquid polymer resin in an uncata-lyzed state.  Catalyst containing frangible ampoules are also positioned in the drum with a rotatable mixer mechanism.  At a waste filling station, the mixer is rotated to break the ampoules so as to mix the catalyst and the resin.  The cata-lyzed resin is then mixed with added waste material to com-pletely encapsulate the waste prior to solidification of the resin.  Monitoring of the filling and mixing process is pro-vided by continually sensing the torque force being applied to the rotating mixer mechanism.  Where the waste is a dust-like, dry particulate material, dust control means and method are also provided.

Abstract: ABSTRACT OF THE DISCLOSURE A temperature regulation system for use in an electric vehicle auto-matically provides for open-loop and closed-loop operation.  In the closed-loop mode, air is forced through the electric motors of the vehicle, and is then delivered to selected components of the vehicle to keep them warm and dry. In the open-loop mode, outside air is allowed to enter the system to prevent overheating of critical components.  The system is intended for use in an electric vehicle, such as a fork lift truck, which must alternate between operation in extremely cold environments and operation at normal temperatures.

Abstract: ABSTRACT OF THE DISCLOSURE        A system for warning that a portion of a crane or other construction equipment has reached one of the boundaries of a working space.  The system includes a laser transmitter that emits a beam which scans about a scanning axis to effect a curtain of light which defines a boundary of working space.  Photosensors mounted on the outboard portion of the construction equipment generate warning signals to the construction equipment operator and other nearby personnel whenever these photosensors move into the light curtain.  Additional curtain sensing equip-ment positioned to intercept the rotating laser beam with each cycle of rotation develops an alarm signal which activates an alarm horn and/or alarm light whenever the laser transmitter fails to provide the light curtain.  The additional curtain sensing equipment is mounted an appropriate distance from the laser transmitter so that such additional sensing equipment will not interfere with the reception of the light curtain by the photosensors on the crane, an the laser transmitter and the additional curtain sensing equipment are mounted several feet above the ground to prevent foot traffic and vehicle traffic from producing false indications of a laser transmitter failure by intercepting the light curtain.

Abstract: ABSTRACT OF THE DISCLOSURE      In a dynamoelectric machine having a rotating field and a stationary stator core, electrical conductors are contained within axially-extending radial slots which are part of the stator core construction.  The electrical conductors for stator bars are subject to electromagnetic forces and thermal cycling effects which, over a period of time, tend to cause the stator bars to become loose within their slots.  The invention is an improved weding system which provides both an immediate and residual force on the stator bars which holds the bars in place even after certain steelements have taken place.  Further, it is possible to determine the amount of force applied initially to the stator bars by the wedging system and any residual force after a period of operation.

Abstract: ABSTRACT A VOICE SWITCHING ARRANGEMENT FOR     TELEPHONE CONFERENCING In a telephone conferencing system, a voice switching arrangement allows a speaker who has seized the line to hear and thus permit an interrupting speaker an opportunity to talk.  This arrangement is achieved in a multiparty connection by using two complementary comb filter banks (118,119)  on a voice channel with the filter passbands of the first bank being stopbands in the second band and vice versa.  During the time when only one speaker is talking, a full voice channel is provided for the speaker.  When an interrupting speaker also begins to talk, the first filter bank (118) is inserted in the speech signal path of the speaker who has seized the line and the second filter bank (119) inserted in the speech signal path of the interrupting speaker such that the first speaker and the interrupting speaker receive each other's speech signals.
