Filed: 1985-10-31
Abstract: PURPOSE:To pass the air throughout the whole area of filter element uniformly by providing a guide plate on the section facing opposedly to the air inlet of housing of the supporting cylinder located on the central part of filter element. CONSTITUTION:The boss 43 of the air cleaner 1 facing opposedly to the air inlet 2a forms a crescent-shaped guide 43a. When the engine is driven, the air is sucked in from the air inlet 2a.

Title: Flinging-up loader for signature machine
Inventor: JIEEMUZU EFU KOSUGUROOBU
IPC: B65H1/30
Filed: 1989-09-21
Abstract: PURPOSE: To always maintain a piling height in a hopper constant for stabilizing the state of a signature by providing a control means for answering to a piling-up detecting means to actuate a conveyor driving means when the piling-up height in a feed-in hopper lowers less than a fixed value. CONSTITUTION: When a signature is removed by an extracting device, the signature in a hopper instantly moves forward. The signature on a loader 10 therefore somewhat tilts forward to lower a piling-up height in a joint part between the loader 10 and a feed-in hopper. A microswitch 76 detects the piling-up height of the signature, and actuates a drive motor 108 for the loader conveyor when hits height lowers less than a prescribed value. Thus the piling-up height in a joint part can be maintained at the prescribed value.
