Title: Safety device for ladders
IPC: E06C/
Filed: 1982-05-26
Abstract: The device is a substantially rectangular frame which can loosely girdle a ladder for sliding movement along the ladder and across the ladder from front to back. The frame has a U-shaped abutment 15 in one longer side 12; this abutment lies at the front side of the ladder and extends towards the ladder. When the device is moved rearwards so that side 12 abuts the front of the ladder, the abutment 15 extends between the ladder stiles 21 into the longitudinal plane of the rungs 22. The device has a spring clip 14 in its rear side 13 and can be attached to a person's belt of harness. In use the person can move up and down the ladder with the safety device hanging forwards (A) so that the abutment does not engage the rungs. If the person slips his movement will draw the device rearwards and bring the abutment into the space between two rungs (B). A short downward movement of the device will then bring the abutment to overlie the lower rung (C) and arrest any further downward movement of the device and to the person attached to it. <IMAGE>

Title: Can beading apparatus
Inventor: MILLER STANLEY JAMES
IPC: B21D15/06
Filed: 1983-01-18
Abstract: Apparatus is provided for forming a chime bead adjacent the closed end of a seamless cup-shaped metal can body and a plurality of peripheral beads intermediate the opposite ends of the can body. The apparatus includes a plurality of beading spindles receiving and supporting can bodies for movement along an arcuate path. The beading spindles are provided with beading tool portions corresponding to the chime and intermediate beads to be formed on a can body.

Title: The measurement of the sizes of particulate matter dispersed in an aerosol
Inventor: ALLEN DR RAY WILLIAM KENNETH
IPC: G01N15/02
Filed: 1983-04-22
Abstract: A method for measuring the sizes of particulate matter dispersed in an aerosol comprises the operations of passing an aerosol the sizes of the particulate matter dispersed in which are to be measured sequentially through a plurality of beds 1, 2, 3 of foraminous material, measuring the amount of particulate material collected by each bed of foraminous material in a given interval of time, deriving therefrom the penetrations of the particulate material through each of the beds of foraminous material prior to the final one, and deriving therefrom an estimation of the sizes of the particulate matter in the aerosol. Removable rings 4, 5 of cotton lint or glass wool extract the liquid collected by filter beds 1 and 2 and are weighed at the end of a predetermined time together with the final filter bed 3 which collects the particulate matter remaining in the aerosol after passage through beds 1 and 2. <IMAGE>

Title: Mat holders
Inventor: JONES W GREGORY
IPC: A47G27/02
Filed: 1985-02-08
Abstract: Improved holder specially adapted for disposable floor mats to be placed adjacent entryways to factories, industrial buildings, or the like or for use in connection with clean rooms, hospitals, laboratories. The holder includes a flat base adapted to hold the mat and at least one hingedly connected side flap adapted to fold over on top of an edge of the mat and securely retain it in position. Means are included to hold the flap against the mat in a closed position to firmly resist movement that would cause wrinkles or bunches in the mat which could cause trips or falls.

Filed: 1985-03-05
Abstract: In a CRT display unit coordinates of start and end points P0, P1 of a line on the screen of the CRT are provided from a controller 11 and stored in a register 12. A line information calculating portion 13 calculates information necessary for linear interpolation based on the stored start and end point coordinates and the line segment information thus obtained is stored in a register 14. Based on the stored line segment information, a coordinates interpolating portion 15 calculates base line and supplement line data comprising a plurality of dots for constituting a straight line connecting the start and end points, which data are stored in a frame memory transfer register 16, A, B, C, prior to transfer to a frame memory. Thus, base and supplement line data are simultaneously transferred for linear interpolation and at the same time, information of the subsequent line segment is calculated so that the processing time for linear interpolation can be made short. <IMAGE>
