Title: Fitting O=rings on shafts - involves tool with radially disposed fingers to expand O=ring over shaft
Inventor: AUGENSTEIN HELMUT
IPC: B23P19/08
Filed: 1989-06-06
Abstract: O-rings are normally stretched over the shaft and snapped into place by hand, but the task is awkward to perform and can result in damage to the O-ring and faulty sealing. The fitting tool has radially disposed fingers over which  the O-ring is placed before fitting. The fingers are then forced outwards against return springs by means of a conically ended peg which may be pneumatically, hydraulically or electrically driven. The expanded O-ring is  positioned over the shaft and axially pushed into place by a stripper mechanism. USE/ADVANTAGE - Simplifies awkward manual task. Avoids damage to O-ring.

IPC: G09F13/20
Filed: 1989-06-19
Abstract: An illuminated display unit such as a board with a house number thereon or an advertising billboard, has a light guide panel. At least one electrical illuminating element is arranged in the vicinity of at least one lateral limiting edge thereof. The light guide panel serves for illuminating logo symbols, which are preferably in the form of film or of vapor coated layers, on the light guide panel. At least one of the lateral limiting edges of the light guide panel is provided with a light guide batten whose thickness is in excess of the thickness of the light guide panel and at least one of the illuminating elements is mounted in the batten. The transition between the light guide batten and the light guide panel is designed so as to have a high optical conductivity or transmittivity. The external surfaces of the light guide batten are provided at least partly with an inwardly reflecting layer. This makes it possible for the light of the illuminating elements, which are more especially in the form of LED's with a large diameter, to be fully introduced in substantially thinner light guide panels in order to reduce costs and weight.

Title: Spark discharge regulation esp. for electrohydraulic surface cleaning - generates signals to adjust electrode to workpiece distance in relation to variations from ideal discharge current impulse
Inventor: ECKLEBE KLAUS-PETER DR ING
IPC: G10K15/06
Filed: 1989-09-05
Abstract: Control process for regulating the spark distance of electrode systems esp. in untriggered electrohydraulic installations for cleaning castings, has the peak value of a discharge current impulse compared with a predetermined ideal value range.  Depending of the difference between the theoretical and actual values, the spark distance of the electrode system is varied in such a way that should the upper value of the theoretical range be exceeded by up to 100%, the spark distance is increased by an amount (S1) equal to the discharge voltage divided by 5 times 10 to the minus 6, volts per metre.  Should the upper range of the theoretical value exceeded by up to 200%, the spark distance is increased by 2.5 times S1.  If the disparity is more than 200% then the adjustment is 5 times S1. Should the value fall below the lower limit of the theoretical value range then the spark distance is restricted to around the level The equation linking S1 to the discharge  voltage Ue is: S1 = Ue/5 x 10 power (-6) V/m. ADVANTAGE - Castings with complicated surface structures are readily treated and the spark distance is regulated sufficiently precisely should the discharge impulse sequence not be uniform.

IPC: B09C1/02
Filed: 1990-09-01
Abstract: In oil removal from finely divided solid material, esp.  metal-contg. prodn. residues and contaminated soils, by washing with an aq. wash liq. to emulsify the oil and then separating the wash liq. from the solids, the novelty is that the solids are intensively mixed and sprayed with emulsifier in the absence of water prior to washing and are then mixed with the wash liq. by stirring in a vessel during the washing process. Appts., for carrying out the process and similar processes, includes a stirrer vessel having ultrasonic emitters mounted on its walls. Mixing of the solids may be carried out in a free-fall mixer or a forced mixer, opt. employing an air stream or vibrations to loosen the solids. If the solids have a suitable consistency, they may be fluidised in a closed mixing chamber while emulsifier is introduced as a fine mist. The solids, wetted with emulsifier, may be stored before the washing operation.  The wash liq. is pref. free from emulsifier and is pref.  mixed with the solids under ultrasonic vibration.

Title: Tool for machining out ring liners - has tool-bit guided by mechanical follower running on outer surface of ring
Inventor: BOOTHROYD ALLAN E
IPC: B23Q35/10
Filed: 1990-10-04
Abstract: In rotating machines such as turbines there are ring-like components with thin internal liners which must be removed after a period of service and replaced. Conventional methods of removal by turning on a vertical lathe may result in damage to the underlying surface because the component is distorted and deviates from true circularity. In the modified system the toolbit (22) is clamped in a holder (32) which is free to move radially on a slideway (34).  Fastened in the holder is a follower (26) which lies opposite the toolbit and is forced against the outer cylindrical surface (16) of the component (10) by a spring (30). The distance between the toolbit and the follower can be adjusted by a micrometer screw (28). When the liner is being machined out the toolbit will follow distortions of the ring and only remove lines material. USE/ADVANTAGE - Accurate, easily adjustable method of removing liner material without damage to component.
