Abstract: A formwork (1) for surfaces with varying curvature has a formwork skin (2) which can be adjusted with respect to its curvature, bearers (3) supporting the latter and a chord arrangement which acts on the bearers (3) at a distance from the formwork skin (2), is formed by individual chord pieces (4, 5) bridging the bearers (3) and is expediently fastened to the outer sides of the bearers (3) facing away from the formwork skin (2). The adjustment of the curvature of the formwork skin (2) is carried out by changing the effective length of the chord pieces (4, 5) between the bearers (3). The mutually opposite formwork elements are able to be braced with respect to one another by means of formwork tie rods (6). In this arrangement, as chord piece, a cross member (4) acts on a formwork element at at least two bearers (3), the said cross member at the same time being provided as an abutment for the formwork tie rod (6), which is consequently arranged between two bearers and the forces of reaction of which are transferred to the two bearers. The cross member is in this case likewise able to be changed with respect to its effective length by its fastening point being adjustable in the direction of its longitudinal extent and transversely to the orientation of the bearer, so that the cross member (4) both provides an adjustable chord piece when changing the curvature of the formwork skin (2) and absorbs the tensioning forces. <IMAGE>

Abstract: An  animal  sticking  apparatus  for  sticking  an  animal to be slaughtered   comprises   a   sticking   tool  having  two  rotary  or oscillating  cutting  blades  and  support means mounting the sticking tool  for  insertion  and  withdrawal  movements.   The cutting blades perform  a  cutting  operation  upon  insertion and advancement of the sticking  tool  into  the thoracic entrance of the chest cavity of the animal,  the  sticking  tool  cutting  tissues  as  it is advanced and enabling  the  stick  wound  to  remain  open  upon  withdrawal of the sticking  tool  to  promote  rapid  exsanguination.  The sticking tool after  insertion  into  the  animal  is pivoted about a remote axis to sever  blood  vessels  near  to  the animal heart ensuring massive and rapid  blood  flow.  A pair of cutting blades are operative to cut the hide  of the animal to form a pre-cut before insertion of the sticking tool,  the  blades  being  movable  apart  to separate the hide at the pre-cut  so  as  to  expose a substantially sterile surface into which the  sticking tool is inserted.  The pre-cut blades have cutting edges forming  an acute angle to the hide surface and cause a cutting action from   the   hide  inside  surface  to  the  outside  for  maintaining substantially sterile conditions on the inside of the hide pre-cut.

Granted: 1995-04-18
Abstract: A signal detecting device can make determination whether to carry out or not automatically dialling transmission by detecting an identification signal sent from an exchange system via a telephone line.  The frequency variation of the identification signal is constant since the identification signal is a composite wave of a plurality of constant frequency signals.  A pulse train having substantially a constant number of pulses can be obtained by comparing the level of the identification signal provided from the telephone line with a predetermined reference voltage by voltage comparators.  Frequency counters count for a constant time period the number of pulses included in the pulse train provided from voltage comparators.  According to the count result output of frequency counters, a determining circuit makes determination whether an identification signal is received or not.
