Insect larvae of a variety of types are raised successfully on a feed containing a variety of nutrient ingredients admixed with a small amount of soybean solids as a gelling agent and nutrient. The soybean solids are present in the amount of 5-20% by weight of the final gel composition. The nutrient composition may also be provided as a solid mixture which is formed into a gel on addition of water, the soybean solids being present in the desired proportion in the final gel composition.

The sharpening stone is readily attachable in a chuck of an electrically powered sabre or jig saw. The sharpening stone is secured to a metal device (shaped to fit the saw chuck) by adhesive bonding or molded into the stone. The sharpener is especially effective for sharpening hand tools including power rotary lawn mower blades.

An apparatus for encapsulating additives in resealed erythrocytes using dialysis is disclosed. A specimen holder, provided with vertical rotation means, is immersed in a dialyzing solution. Means are also provided for: agitation, cooling, heating, temperature control and measurement of the dialyzing solution.

Apparatus for encapsulating additives in resealed erythrocytes

A process for encapsulating additives in resealed erythrocytes from the blood of certain mammals. The invention provides a method of preparing material in substantial quantities, to be employed as vaccine which, when reinjected into these mammals, provides a systemic protection against bloodsucking insects or other parasites.

A plurality of cantilever beams, each fitted with a calibrated strain gage, are arranged to pivot on a corresponding plurality of upstanding pivots located near one end of each beam of a steel plate. A cylindrical specimen threaded at each end is disposed vertically between one end of each beam and the steel plate with a machined nut and socket at each end of the specimen to provide self-alignment. A self-aligning hardened steel stud is threaded into the plate and held in a hole in the other end of each of the beams with a nut and socket. A tension load is applied to the specimen by torquing the nut on the stud, with the mechanical advantage being proportional to the relative distances between the pivot and the specimen and the pivot and the stud.
