Title: Financial Management Data Cabinet Based on Face Recognition Technology
Inventor: TIAN YANGYANG
IPC: G07F19/00
Filed: 2023-07-05
Granted: 2024-01-10
Abstract: The invention discloses a financial management data cabinet based on face recognition technology, and the financial management data cabinet based on face recognition technology includes a data cabinet body, wherein the top of the data cabinet body is fixedly connected with a fan, the right side of the fan penetrates and is fixedly connected with an air suction pipe, the left side of a carbon dioxide storage box penetrates and is fixedly connected with an air pump, and the top of the air pump penetrates and is fixedly connected with an air outlet pipe. In the invention, a second motor drives fan blades to rotate to generate suction force, so that the air suction pipe sucks out the air in the data cabinet, the air pump sucks out the carbon dioxide in the carbon dioxide storage box, and the carbon dioxide enters the branch pipe through the air outlet pipe to be sprayed out, thereby extinguishing the data cabinet.

Title: Small fold-up case with outer covering - comprises two-part frame members initially punched out from metal blank
IPC: A45C11/24
Filed: 1975-08-26
Abstract: The hinged case comprises two support frames (1) which each consist of a lower L-shaped frame member (2) with one arm (3) lying in the plane of the frame and the shorter inner arm (4) lying at right angles to this plane, and of an upper frame member (5) which comprises an arm (6) lying in the plane of the frame, an inner arm (7) at right angles thereto and a shortened outer arm (8). This transverse division of each support frame into two inter-engaging frame members provides for easier manufacture of the frame since the frame members can be punched out in one work step from a blank sheet and then bent into the right shape. Furthermore the edges of the outer covering (10) can be cemented more easily with the outwardly aligned horizontal arms of the lower frame member (2).

IPC: A01D90/10
Filed: 1978-06-29
Abstract: The loading truck has a lowerable upper truck body (3) for the purpose of adapting the loading space and the truck height to different conditions of use. An unloading device in the form of cutting rollers (7, 8) arranged horizontally and one above the other is located in the end region of the truck. There is the problem of also covering the upper region of the loading space by the cutting rollers, because, without such cover, the upper part of the loading space in the region of the lowerable truck body cannot be utilised for short cut material. To solve this problem, an uppermost cutting roller (9) is arranged in the region of the lowerable truck body (3) and is made lowerable at least to below the upper limitation (39) of the latter. This cutting roller (9) is preferably mounted on pivotable supporting arms (15, 15'). This guarantees a perfect cover of the upper region of the loading space by the unloading device and at the same time avoids the arrangement of complicated removable cutting rollers having a mounting involving a high outlay. The arrangement of a baffle wall (20) connected to the uppermost cutting roller (9) for joint movement and/or a connection of this cutting roller in its adjusting movement to the lowerable truck body (3) is especially advantageous. <IMAGE>
