Abstract: A worker safety device for use with an object having a person support surface, the device comprising: a length-adjustable device frame positionable on said object; a frame fastener coupled to the device frame configured to detachably fasten the device frame to the object; an attachment means, attached to the device frame, configured and positioned to attach a personal fall-prevention device to the device frame; whereby a person on said surface using the fall-prevention device can prevent a fall from said surface by attaching the fall-prevention device to the attachment means.

Abstract: A safety barrier system for use in constructing multi-storey buildings has elongated safety barrier panels extending upwards from a first floor level a sufficient height to serve as effective safety barriers during the work for the subsequent floor. The panels are supporterd at their side edges in tracks along which the panels can slide. The tracks are duplexed (siamesed) so as to link the respective safety modules into a continuous peripheral barrier. The respective panels and tracks are braced and independently supported, permitting the system elements to be ‘walked’ piecemeal up the face of a structure as required during its erection. Auxiliary barriers supplement the displaced panels, on lower levels, while toe-boards protect the floor-to-panel gap.

Abstract: A method for producing a desired amount of ice crystal formation in a beverage comprising the steps of cooling said beverage to a temperature below its ordinary freezing temperature at atmospheric pressure to form a cooled beverage; maintaining said beverage at a pressure sufficient to inhibit freezing of said beverage; dispensing said cooled beverage into a vessel; obtaining a cooled surface, having a temperature sufficiently low to cause flash freezing of a portion of said cooled beverage which comes into contact therewith; and presenting said cooled surface to said beverage for a time sufficient to form a desired amount of said ice crystals in said beverage. An apparatus is provided for carrying out the method.
