Abstract: There is provided a downhole hammer including a drill bit (2) retained by short (4) and long (5) drive pins in the bore of a driver chuck (1). The chuck (1) and bit (2) shank have machined longitudinal grooves (3), every second bit shank groove being blind and connected to the adjacent open groove by a short-pin-length relief. The shorter pins (4) are inserted into the visible holes formed by the alignment of the open drill bit grooves and driver chuck grooves (3). The chuck (1) is then indexed which shunts the short pins (4) sideways until the longer pins (5) are insertable. The driver chuck (1) and drill bit (2) are engaged rotationally. The bit (2) slides by the desired distance due to the shorter pins (4) being entrapped in the blind grooves. The arrangement does not require a bit shank extension to accommodate a conventions bit retainer ring.

Abstract: Fertility problems affect (1 in 10) couples in Western society, making it one of the most common serious health issues. Despite this, little is known about the causes of infertility, and thus patient counselling and treatment are suboptimal. With infertility being such a common problem, identification of any cause would impact on a large number of patients, allowing better counseling, clearer diagnoses and the possibility of making more informed choices (e.g. adoption vs. IVF treatment). The present invention provides methods to identify a cause of infertility in a subject based on the genotype of the subject, in particular, by evaluating the status of the gene encoding FK506 binding protein-like (FKBPL). In particular, the present invention relates to use of the status of the gene encoding FK506 binding protein-like for identification of a cause of an infertile phenotype in a subject. Also provided, are methods method for identifying an infertile phenotype in a subject, and identifying a cause of an infertile phenotype in a subject.  This diagnostic tool finds wide clinical utility in the identification of a cause of infertility, resultantly impacting on a large number of patients. Further aspects of the present invention relate to the targeting of FKBPL in order to temporarily and reversibly induce infertility in a subject. Such aspects of the present invention find utility in the development of a male contraceptive pill.  Moreover, due to the high degree of homology between the human and mouse FKBPL gene, FKBPL can be targeted in order to induce infertility in mice (or other species) as a form of pest control or animal husbandry.
