As shown, each carrier 11 includes a shackle 14 which is released, under the control of unit 22, by one of three pneumatic release units 23-25 so that a carcass carried by the shackle 14 falls into one of three bins 26-28 according to which of three weight ranges its weight lies in. The weight of each carcass is applied in turn to the load cell 101 by a rotatable shaft 102 having radial spokes 104 with forked ends which engage chains 13 from which the shackles 14 are suspended so as to lift each shackle and carcass carried thereby on to a roller 104 on a shaft 105 acting as a weight sensitive member for the load cell 101. The signal emitted by cell 101  may be stored by the control unit 22 for a predetermined time or until a predetermined number of carcasses has passed a fixed point. In an alternative arrangement, Figs. 3 and 4  (not shown) the carcasses are weighed at a 180 degree bend in the conveyer and the carcasses are swung outwardly at the bend so ensuring an increased separation between successive carcasses at the weighing station. In this arrangement the sight sensing device may comprise one or more load cells to monitor the compressive load on the radial spokes. Alternatively the shaft 102 and spokes 103 may be replaced by a floating portion of rail either part of or additional to the rail 10. Each carcass may be weighed more than once by the same or different weight sensing devices to ensure greater accuracy. One or more reference weights carried by the conveyer in place of carcasses may be used to check and calibrate the sensing device(s). Provision may be made for automatically adjusting the weight ranges into which the carcasses are sorted according to the rate at which carcasses are sorted into particular ranges.

Title: Improvements in artificial limbs
IPC: A61F2/60
Filed: 1920-11-10
Abstract: 171,613. Power, R. F. Nov. 10, 1920. Limbs, artificial.-The knee joint of an artificial leg of the kind automatically locked at predetermined positions of the heel or articulated toe member, is locked by means of a pivoted spring-pressed pawl engaging a ratchet-wheel fast to the usual knee-bolt, the unlocking being effected by movements of the toe or heel, the motion being transmitted by a Bowden cable. In the construction shown in Fig. 1, two spring-pressed pawls 11, 12 are employed in conjunction with the ratchet-wheel 8 fast on the knee-bolt ,4 both of which are kept normally out of engagement with the ratchet-wheel against the action of the spring 28, one by the spring cushion 21 which, when the foot is released from the weight of the body, forces forward the toe 20 thus straining the Bowden cable 17 and pulling down the pawl 11, and the other by means of a spring 27 which pushes the heel downwards, thus straining the Bowden cable 24. As soon as the weight of the body comes on to the foot the force of either the spring 27 or cushion 21 is overcome, according to whether the heel or toe is placed on the ground first, the Bowden cable is released and either the pawl 12 or 11 is forced into engagement with the ratchet-wheel under the action of the spring 28, thus locking the knee joint until the foot is taken from the ground. In a modified construction, the pawl and Bowden mechanism associated with the heel-piece are dispensed with, and the toe-operated pawl-releasing mechanism comprises a system of levers attached to a Bowden wire.
