Title: Sterile product mfr. from animal scrap and infected bodies - where solid material is separated off and dried to produce meat meal while remainder is dried under vacuum to produce fat and protein
Inventor: NEUMAYER WALTER
IPC: A23L13/20
Filed: 1989-10-06
Abstract: A process is described for processing all types of animal scrap and infected animal bodies into germ free products. The invention achieves a reduction in the number of process stages, uses less equipment and reduces energy costs and environmental damage. Continuous removal of fat from the scrap material is achieved in a pressurized, sterilizing vessel with a paddle. The process is realized at low temps. under steam pressure and overcomes the boiling pressure before sterilization of the raw materials. Sterile, cooled solid material is separated off and dried to produce meat meal and the remaining product is dried in a vacuum evaporator using waste process heat to produce fat and protein. USE/ADVANTAGE - Processing animal scrap and infected bodies into sterile products. Process costs are reduced and less equipment is used.

Title: Stamping tool for flat material - with light-metal circumferential layer which is treated to produce hard coating after stamping profile is obtd.
Inventor: WILL ROLF
IPC: B23P15/40
Filed: 1991-08-05
Abstract: The device for through-stamping of flat material, esp. labelling material on a carrier material which is not to be stamped through, is a roller (6) with a stamping profile (8) produced by milling and subsequent application of a hard circumferential layer. The circumferential layer of the roller (6) - at least within the region of the proposed stamping profile - consists of a relatively soft light metal. After the stamping profile (8) has been produced, the surface of this layer is treated to produce a hard coating. Pref. the relatively soft light metal is an aluminium alloy, in particular AlMg3 or AlMg4, 5F48. The hard layer is an electrically produced hard aluminium oxide coating. The roller (6) is provided at each end with rings (2, 4) with a relatively hard circumferential surface whose radius is larger than the radius of the stamping profile (8), pref. by an amt. equal to the thickness of the material (22) carrying the labelling material (20). The rings (2, 4) are made of an alloy tool steel (in particular as specified in DIN 12 436). They are mounted onto the hubs (12, 14) of the roller (6). USE/ADVANTAGE - Used in stamping equipment producing, for example, labelling items. Stamping tools based on it can be produced at a lower cost than the traditional all-steel tools, as a consequence of higher possible milling rates and a reduced milling cutter wear.
