Abstract: A process for the hydroformylation of olefins to aldehydes is disclosed. The process comprises: hydroformylating one or more olefins with hydrogen and carbon monoxide in the presence of a ligand-rhodium catalyst in a reaction zone; recovering a reactor effluent from the reaction zone, the reactor effluent comprising product aldehyde and the ligand-rhodium catalyst; passing the reactor effluent and a strip gas to a vaporiser, wherein the strip gas comprises carbon monoxide and is formed from a recycle strip gas stream and a make-up strip gas stream, wherein the product aldehyde is vaporised into the strip gas in the vaporiser resulting in a vapour mixture, comprising the strip gas and the product aldehyde, and a liquid mixture, comprising the ligand-rhodium catalyst; recovering the liquid mixture and recycling the ligand-rhodium catalyst to the reaction zone; recovering the vapour mixture and separating the product aldehyde from the vapour mixture.

Abstract: An attachment apparatus for a crutch including a pair of horizontal supports, a rectangular attachment having a back side and a front side, and a pair of clips. The pair of horizontal supports includes an upper support and a lower support. A right end of each of the upper support and the lower support, and a left end of each of the upper support and the lower support are attached to a right side support of a crutch and a left side support of a crutch, respectively. The pair of clips includes an upper clip and a lower clip. Each of the upper clip and the lower clip has a female receptor and a male member. Each of the female receptors is disposed on each of the pair of horizontal supports, and each of the male members is disposed on the back side of the attachment.

Abstract: Apparatus and methods to signal to a user that his/her head is not upright and methods for using such apparatus. For example, the present invention may be an apparatus that includes a tapered resilient block locatable underneath the mandible of a user and retention apparatus to maintain the position of the tapered resilient block.

Abstract: Apparatus to support a user's head. For example, the apparatus may include a shaped resilient block locatable adjacent the neck of a user and, may include a retention apparatus to maintain the position of the shaped resilient block.
