Title: Control apparatus for fluorescent lamp crusher
Inventor: MULLER-GIRARD OTTO
IPC: B02C23/04
Filed: 1996-02-09
Abstract: As each tube is fed into the feed chute of a fluorescent lamp tube crusher, and regardless of the size of the tube, a sensor switch in the chute immediately sends a count signal to an associated tube counter, and also produces an inhibit signal which prevents a second count signal from being applied to the counter for a predetermined interval of time that is greater than the time it takes to grind up a tube of a first size and that is less than the time it takes to crush a tube of larger size.  If at the end of the interval a tube of larger size is still being crushed, a second count signal is applied to the counter.

Filed: 1994-09-01
Abstract: A reverse pulse cleaning system for use in a bag house filter including a blow tube (2) having outlet holes (3) to direct high velocity air pulses into filter bags to be cleaned. The system includes a nozzle (1) which may be an assemblage of parts, which has a control formation at or in between an inlet or outlet of the nozzle. The control formation determines the characteristics such as velocity and direction of the flow emergent from the outlet holes (3) and can improve uniformity and effectiveness of filter bag cleaning. A clampable and releaseable fixing of the nozzle (1) to the blow tube allows replacement of the control formation with one of different characteristics during manufacturing or in situ fine tuning. The fixing allows precise alignment of nozzles (1) on assembly which reduces the need for costly precision in forming the blow tube outlet holes (3). The system may include a tube (9) forming part of the nozzle with adjustable radial holes (13) to induce secondary air into the cleaning flow and may include a venturi (10) to induce tertiary air.
Patent CA-2173631-A1 (CA)
Title: Magneto-optical recording apparatus, medium, and method
Inventor: MEOUCH IVAN
IPC: G11B11/105
Filed: 1996-04-09
Abstract: A magneto-optical recording apparatus records information on a magneto-optical recording medium composed of memory layer, writing layer and initializing layer which are disposed on a substrate, each comprising a magnetic thin film of amorphous-rare-earth transition-metal alloy. The layers are magnetically coupled directly, or through an intermediate layer therebetween, to each other under an exchange force. The magnetization of the initializing and writing layers is aligned in a single direction. The initializing layer has its compensation temperature, Tcomp3, and its magnetization of the TM subnetwork, Mtm3, is antiparallel to that of the RE subnetwork, Mre3. The netmagnetic moment of the initializing layer, Ms3, exhibited by the material is the vector sum of the two antiparallel subnetwork magnetizations, Ms3 = Mre3 + (-Mtm3). The Curie temperature of the three layers ( Tc1, Tc2, Tc3 ), and the temperature T31 at which the RE-rich antiparallel RE-TM magnetization of the initializing layer is copied to writing layer, and the temperature T32 at which the TM-rich antiparallel RE-TM magnetization of the initializing layer is copied to writing layer are ordered as follows:   T31 < Tc1 < Tc2 < T32 < Tc3 In order to write a "1", the film temperature raised to the Curie temperature of the writing layer, Tc2, which is above the Curie temperature of the memory layer, Tc1, and above the compensation temperature of initializing layer, Tcomp3, so the direction of the net moment of initializing layer, Ms3, is changed from RE-rich magnetization to the opposite directed TM-rich magnetization, when the temperature falls below Tc2, at the temperature T32, which is above Tcomp3, the sublattice TM-rich magnetization of the initializing layer is copied to the writing layer, and at the temperature dropped below Tc1 the exchange coupling causes the sublattice magnetization of the writing layer to be copied to the memory layer - that is, a "1" is written. At the further dropped temperature T31, which is below Tcomp3, the RE-rich sublattice magnetizaion of initializing layer is copied to the writing layer, however, this magnetization is not copied to the memory layer. The sublattice magnetization of the writing layer and the net magnetization of the initializing layer are in the same (Mre3) direction, regardless of their past states. In order to write "0", the film temperature is raised to the vicinity of Tc1, then, when the temperature falls, the sublattice magnetization of the writing layer is copied to the memory layer - that is, a "0" is written.

Patent CA-2194346-A1 (CA)
Inventor: BECKER ALBERT
IPC: F16K27/04
Filed: 1997-01-03
Abstract: A sanitary water fitting having a bearing ring arranged as a sliding bearing between the fitting body and the bearing sleeve. The bearing ring seals off a circling groove holding sealing rings from the bearing sleeve and is itself sealed off from the bearing sleeve by means of an external seal placed at the bearing ring. In its axial extension it borders a water passage opening which is between a circulating water channel and a swivel spout connection piece. The advantage of this invention is that the water flow in the circulating water channel and towards the swivel spout connection piece is controlled in such a way that the formation of lime deposits in the area of the sealing rings is considerably limited even after a relatively long period of operation, or even prevented completely. Since the water can no longer get in between the parts moving in relation to each other and the bearing ring itself helps to protect the sealing rings, there is no longer a possibility of serious levels of lime deposits settling in this sensitive area.
