Title: Coffee mill with encased grinder and large delivery outlet - has safety measures in outlet preventing access of fingers to grinder
Inventor: SMITH ROY
IPC: A47J42/56
Filed: 1974-12-21
Abstract: The coffee mill housing (1) contains a grinding chamber (2) with supply shaft (3) and grinding discs (4, 5) driven by a motor assembly (6, 7) wherein the ground coffee is delivered through a discharge opening (10) which is fairly large to allow unimpeded delivery of the coffee without any danger of blockage. To prevent fingers from entering the grinding chamber (2) and contacting the dangerous grinding discs, at least one, preferably several thin bars (13) are mounted in the delivery outlt (10) to extend parallel or criss-cross across the outlet to provide a kind of safety mesh. These bars are however very thin so that they do not in practice reduce the cross-sectional area of the outlet so that the motor capacity of the mill is not affected.

Title: Continuous bar forming press - compacts discrete quantities of powdered metal sequentially to form a continuous bar for sintering
Inventor: LOHMAN GORDON RUSSELL
IPC: B30B11/26
Filed: 1975-06-03
Abstract: Continuous bar forming press includes a die unit and means for introducing a selective amount of powdered metal into the die cavity. A ram and punch are reciprocable to and from the die. Up and down limit switches are engaged by the ram to control and reverse the movement of the ram in response to the engagement of one of the switches. On the advance stroke the ram moves the punch into the die cavity. The down limit switch can be relocated to adjust the length of each advance stroke of the ram and punch in direct proportion to the reaction pressure during that stroke. A green compact rod of uniform physical characteristics along its length can be obtained. Substantial green strength is obtained in the bar so that it can be handled in the green state without disintegration particularly when being forced out of the die and through the sintering furnace.
