Title: Variable speed control pulley with transmission diaphragm
Inventor: GOURDON ERIC
IPC: F16H55/56
Filed: 1991-01-18
Abstract: The invention relates to a drive pulley for a continuously variable transmission in which the driven pulley is driven by a belt of trapezial section connecting to said drive pulley. 
<??>The drive pulley comprises two coaxial flanges (1, 2) whose flanks (3, 4) confront each other to form a "V" groove (5) in which the belt (6) runs, the non-moving flange (1) is fixed to the end of a hub (7) anchored to a drive shaft (9) and the moving flange (2) can slide axially along said hub (7). A reaction cap (23) is made fast to the hub (7) and hence to the drive shaft (9). As the drive shaft (9) of the pulley rotates, a number of centrifugal weights (30) are subjected to centrifugal forces which cause the moving flange (2) to move towards the non-moving flange (1), and a return spring (19) is provided in order to exert a force in opposition to the approach of the two flanges (1, 2). The moving flange (2) is coupled in rotation to the drive shaft (9) by means of a rubber membrane (35) which connects it to the reaction cap (23) and has a part of revolution which in cross-section is arched. 
<??>The hysteresis generally encountered with this kind of pulley is greatly reduced by this membrane.

Title: Process and apparatus for removing pitch- or tar-containing pollutants present in exhaust gases
Inventor: JUNGK KLAUS
IPC: B01D53/72
Filed: 1991-01-29
Abstract: ABSTRACT OF THE DISCLOSURE           In the baking of green carbon anodes for the production of aluminum,  pitch- or tar-containing pollutants are carried by the exhaust gases in the form of fumes which do not only have a detrimental effect on the operating personnel,  but also on the environment.   In order to avoid this,  according to the invention, the pollutant containing exhaust gases are mixed with a powdery sorbent,  in particular with aluminum oxide powder,  in a chamber to the absorbed by the sorbent.  After separation from the gases, the sorbent,   loaded with the pitch- or tar-containing pollutants,  is fed to a combustion chamber where the pitch- or tar-containing pollutants  are burned  at high temperatures and are subsequently separated from the sorbent in a cyclone.  In this way, the pitch- or tar-containing pollutants which are present in the exhaust gases and which are carried by the exhaust gases during the baking of green carbon anodes for the production of aluminum, can be completely removed in a simple and economic way.

Title: Insulating jacket
Inventor: HUTCHINSON PETER
IPC: A47G9/08
Filed: 1990-03-22
Abstract: A thermally insulating jacket such as a sleeping bag is provided with an inner layer (1) and an outer layer (2) to which are attached a plurality of internal walls (3) so as to define a plurality of boxes. The boxes are filled with insulating material such as down or synthetic material. The inner layer is elasticated by, for example, the provision of elasticated thread (7) which causes the inner layer to pull inwards away from the outer layer. This reduces the space between the inner layer and the person or article being covered by the jacket, so as to reduce heat transfer by convection and also increases the thickness of the jacket, thereby improving its thermal insulation. In addition to sleeping bags, the invention can be applied to articles of high insulation clothing and also jackets for insulating hot or cold water tanks.
Patent CA-2051425-A1 (CA)
Inventor: HARDY GERALD D
IPC: A01B63/112
Filed: 1990-07-16
Abstract: Implement draft control devices are typically utilized on agricultural vehicles such as tractors and on other earthworking type vehicles. Advantageously, such control systems should respond quickly to changing soil conditions, while remaining stable so that the hitch and implement systems do not oscillate or are not changed in a rapid or erratic fashion. The instant embodiment of a draft control system includes a control system that receives hitch position control signals and engine acceleration signals, and controllably modifies the hitch position control signals in response to the rate of acceleration and deceleration of the engine. By utilizing engine acceleration and deceleration rates as opposed to mere changes in engine speed, the system is able to respond quickly to needed changes in implement depth while remaining stable during operation.

Title: Continuous anion exchange chromatography for the separation of zirconium isotopes
Inventor: SNYDER THOMAS S
IPC: G01N30/58
Filed: 1991-10-09
Abstract: The thermal neutron capture cross-section of zirconium may be altered by altering its natural isotope distribution through a steady state chromatographic separation of these isotopes using an anion exchange resin as the stationary phase of the chromatographic column. Zirconium is dissolved in a very strong acid which causes the formation of a zirconium anion, such as the ZrOCl4 -2 anion formed in six normal hydrochloric acid, and eluted off the column with a weaker acid. Distinct elution volumes representative of each isotope are collected. In a preferred embodiment, the process also separates the zirconium from hafnium and the other impurities normally present in the product obtained by chlorinating zircon sand and utilizes a continuous annular chromatograph.

Title: Rotary drum sampling device
Inventor: LYONS RICHARD G
IPC: G01N1/20
Filed: 1991-10-10
Abstract: ABSTRACT OF THE DISCLOSURE       A device for systematic sampling coarse material sliding down an inclined chute. A bottom portion of the chute is removed and replaced by a sampling device mounted below the chute opening. The sampling device includes a drum for receiving the sample, a gate mounted to the bottom of the chute for rotation between open and closed positions and a motor for rotating the drum. The outer surface of the drum is provided with an opening. The drum is rotated until the drum opening is aligned with the chute opening causing the gate to be rotated to its open position. Material is diverted from the chute into the drum. After the sample is obtained, rotation of the drum is continued until the gate is closed so that the material continues to slide down the chute without passing into the drum.

Patent CA-2069646-A1 (CA)
Title: Optical bypass switch
Inventor: TOMITA AKIRA
IPC: G02B6/35
Filed: 1990-12-20
Abstract: An optical bypass switch includes a normal state and a bypass state, a transmission optical fiber having a signal withdrawn therefrom and injected thereto in its normal state so as to be capable of use in a ring or bus architecture. In the bypass state of the switch, the transmission optical fiber is substantially disengaged so that a signal being transmitted thereby can bypass the switch, and in this state optical fibers connected to a transmitter and a receiver of the bypass switch are maintained in a bent attitude so as to allow signals to be withdrawn and injected thereinto. A loop back path, e.g. a connector-optical fiber, is provided which allows a path between the transmitter and the receiver to be completed in the bypass state of the bypass switch, and logic circuitry is provided for analyzing signals detected by the receiver which should have originated from the transmitter for evaluating a state of operation of the transmitter, receiver, and connecting means therefor. Whenever the logic circuitry detects a malfunction in any of these elements, e.g. the transmitter, the receiver and connecting structure therefor, the optical bypass switch is kept in its bypass state and prevented from re-engaging the transmission fiber so as to prevent the bypass switch from optically coupling to the transmission fiber when its electro-optic elements are not functioning properly.
