Title: Lift brake for mine shaft conveyance system
Inventor: PINK EDWING GEORGE
IPC: B66B15/00
Filed: 1991-03-01
Abstract: Ore, personnel or equipment conveyances are driven vertically up and down the shaft as required by electromagnetic forces generated by linear motors. Each motor is constituted by a vertically extending winding support member and a reaction member, typically incorporating permanent magnets. Caliper brakes (22) are mounted on the conveyances or directly on the reaction members. Each brake has a mounting plate (24) which is secured to the underside of the conveyance and a pair of hydraulic brake actuators (26) which act on a caliper carrying brake pads (28) of friction material.  The brake is released when load cells (34) sense a predetermined vertical load on the brake e.g. 90% of the upward thrust required to support the dead weight of the conveyance. Thus caliper pads acting on vertical guide rails may be released by hydraulic actuators operating against spring forces. @(11pp Dwg.No.2/3)@<<>/AB> <EOR> <PNO> DE4106606-A</PNO> <TI> Tie-rod esp. for controlling car engine w.r.t. chassis</TI> <AB> A tie-rod is interconnected between two objects (12, 14) e.g.  a vehicle engine and a vehicle chassis, to limit relative movement of the two objects. An isolator (15) e.g. a resilient spring is rigidly connected to an anchor part (11) connected to one object (12) and a variable length connection (21, 22) is connected between the isolator and another anchor part (13) connected to the other object (14). A detector (18) senses the relative positions of the two objects and this information is used to control the length of the variable length connection to control the relative position of the two objects for example, to maintain the two objects with constant spacing. The length of the variable length connection is varied to compress or extend the isolator so as to resist forces causing relative movement of the objects. Preferably the variable length connection is a piston and cylinder. Position control is provided by an electrical circuit.

Title: Measuring thickness of coating, e.g. of zinc@ on steel, - counting repeatedly applied laser pulses until spectral lines in plasma generated changes
Inventor: CARLHOFF CHRISTOPH DR
IPC: B23K26/08
Filed: 1991-11-21
Abstract: The measurement method involves repeatedly applying a focussed laser pulse of defined duration and intensity to one point on the surface of a workpiece.  The material vaporised from the surface, whose quantity corresponds to the pulse  duration and intensity, is analysed to determine the coating thickness. The spectrum of the plasma produced is analysed  for spectral lines and bands characteristic of elements and/or molecules whose conc. values are determined. The number of pulses is counted until a detectable change in the spectral lines or  bands occurs.  The coating thickness is derived from the number and intensity of the pulses. ADVANTAGE - Accurate results obtained even on inaccessible surfaces.

Title: Sliver can rotating sliver feed plate - has low-friction cover at underside of plate casting to eliminate polishing or grinding
IPC: B65H54/80
Filed: 1991-12-04
Abstract: The cast rotating plate, for the guide channel to pass a sliver into a can for filling, is fitted with a keyed covering plate over its under side, of a low friction material. The covering plate is pref. circular, and with a slightly larger dia. than the rotating plate unit. The edge projecting round the rotating plate is pref. rolled over an edge beading for a secure mounting. The cover can also be flush with the edge of the rotating plate, to be secured to the under surface by welded thread bolts for screwing into place at the under side of the rotating plate, or the flush cover can be adhesive-bonded in place. The covering plate is from sheet stainless steel or brass or is a ceramic plate. The surface of the covering, towards the sliver can, has a lightly structured surface character such as an orange peel or leather grain, to prevent sliver fibres from adhering to the plate cover surface. ADVANTAGE - The rotating plate casting, such as aluminium, has a rough outer surface and blowholes at its under side. The covering over the under side gives low friction against the sliver being passed into and compressed within the can, without polishing or grinding of the under surface, and without casting rejects through poor surface quality.

Title: Electro-hydraulic control circuit for load compensated operation of ram - has venting line with proportional control valve with electronic control for venting rate
Inventor: SANDAU HARTMUT DIPL ING
IPC: F15B21/08
Filed: 1992-01-17
Abstract: The hydraulic ram (11) is controlled in two modes: one for lifting loads and one for lowering loads. The lifting control is purely hydraulic-mechanical using a proportional valve (23) between the pump (18) and the ram while the degree of lifting is controlled via an hydraulic balance valve (32). The lowering of the ram is via a second proportional valve (41) whose characteristics are stored in a program, to release the ram pressure in a controlled manner proportional to the load carried. The processor has a program for the venting flow through the proportional valve w.r.t. valve settings. A single pressure sensor (27) feeds the processor with the pressure changes in the ram supply and the effects of the load on the venting rate.

Patent DE-4209571-A1 (DE)
IPC: B09C1/02
Filed: 1992-03-25
Abstract: A process for the disposal of a waste dump body 1 stored in a waste dump pit, which comprises pollutant bodies 2 of different specific gravities in need of disposal. The waste dump pit is underpinned by means of a sealing structure 4 which prevents the diffusion of fluids from the waste dump body into the geological formations surrounding the waste dump pit and/or into surface groundwater. A heavy medium, the specific gravity of which is greater than the specific gravity of the pollutant bodies to be disposed of, is introduced, see arrows 6, into the waste dump body in an amount which causes the pollutant bodies to float to the surface. The floating pollutant bodies are removed at the surface of the waste dump body. The waste dump body is loosened up if necessary by fluid-flushing. <IMAGE>
