Abstract: A torque transmitting structure for an automatic transmission has an inner hub for rotating the structure and an outer annular shell.  The annular shell has an internal radial spline portion, an external brake surface, a torque tube and an axially facing drive connecting surface.  The annular shell is manufactured in a flow forming process, wherein a cup-shaped blank is secured on a mandrel which has a shape complementary to the internal shape of the shell. Forming rolls engage the outer surface and are moved axially relative to the mandrel in a manner to form the desired outer contour of the shell.  After the flow forming operation, the shell is removed from the mandrel, the axial drive connection is formed by metal removal and the hub is bonded to the shell.

Abstract: Hypodermic syringe or medical sampler has a hollow needle (115) that is automatically retractable after use. A one-piece body (101) moulding has a main chamber for a plunger (105) or sampler container or drug cartridge, a forward chamber (111) to house a spring (133) to bias a needle holder (117), and internal latching formations (141) to retain the needle holder (117) with the spring (133) compressed in the forward chamber until automatic retraction when the latching formations (141) are released by end of plunger movement. Direct plunger-to-body seating involves an over-size plunger head (105 H) forcing head and wall de-formation. Both ends of the spring (133) have seals (119, 160) for the forward chamber (111). The needle, its holder, spring and seals can be installed using a sliding guide. Pressure testing can be combined with needle lubrication, and retraction prevention with sterilising tell-tale. The plunger (105) has top and grip formations (105 F) for the needle holder (117), and the needle can be double ended for taking samples or emptying drug cartridges.

Abstract: The object of the invention is a method of controlling a crane or a similar apparatus, utilized e.g. in controlling an overhead crane, wherein the crane attendant applies velocity request (Vref) from the control system of the crane to the operating means of the crane as control sequences and the velocity requests (Vref) applied by the at-tendant are read into the control system. To improve controllability of the crane, the velocity request (Vref) is compared to the previous ve-locity request and if the velocity request has changed, an accelerating sequenoe for the corresponding change in velocity is provided, subse-quently storing the resultant accelerating sequence, whereafter, or if the velocity request remains unchanged, the changes in velocity deter-mined by the stored accelerating sequences at a given time are added up and this sum (dV) is added to the previous velocity request (Vref), the resultant sum providing a new velocity request (Vref2), which is set as a new control command and velocity request (Vref2) for the op-erating means of the crane.

Title: Transfer switch mechanism
Inventor: SMITH GEORGE ANDREW
IPC: H01H71/10
Filed: 1994-09-27
Granted: 2002-10-08
Abstract: A transfer switch mechanism is provided for operating the handles of a pair of circuit interrupters. The transfer switch mechanism has a lever arm movable between advanced and retracted positions, the lever arm having a gripping portion permitting handhold for manual operation. The lever arm turns an axle via a ratchet assembly with pawls that permit the axle to turn in one direction but oppose movement of the axle in the direction counter to that direction. The axle turns a crank, and a pair of connecting rods have proximal ends coupled to the crank. The transfer switch mechanism further includes a pair of handle-engaging heads, each of which has opposed abutment surfaces that removably receive the handle of one or the other circuit interrupters between the opposed abutment surfaces. A base is fixed relative to the circuit interrupters and movably supports the lever arm and the handle-engaging heads. The connecting rods have distal ends respectively coupled to one of the two heads such that operation of the lever arm between the advanced and retracted positions causes the abutment surfaces to drive against the handles and thereby move the handles between operative positions.

Title: Process for recovering olefins from cat-cracked gas without accumulating undesirable oxides of nitrogen
Inventor: GRENOBLE DANE CLARK
IPC: C10G70/06
Filed: 1993-10-28
Granted: 2004-12-14
Abstract: Recovering olefins from cat-cracked gases without the accumulation of dangerous amounts of nitrogen oxides is achievable in a safe, effective, and economical manner by conducting the recovery at temperatures that are high enough to prevent the oxidation of nitric oxide (NO) to form nitrogen dioxide (NO2) and high enough to prevent the accumulation of unwanted nitrogen oxides. One way to achieve this result is using well known absorber technology to operate the demethanizer rather than using the typical cryogenic technology.      A stream of cat-cracked gas (10) first is scrubbed to remove acid gases, including nitrogen dioxide (NO2), and then is gassed through a depropanizer fractionation tower (12). Hydrocarbons having four or more carbon atoms are recovered in the bottoms (16) of the depropanizer, and the overhead (14) from the depropanizer - which is composed of hydrocarbons having three or fewer carbon atoms - is sent to an absorber demethanizer tower (18). Hydrocarbons having two or more carbon atoms are recovered in the bottoms from the absorber demethanizer tower, where temperatures are no lower than about -46 ° C (-50 ° F). The overhead (20) from the absorber demethanizer tower - which is composed of methan, hydrogen and trace amounts of nitrogen oxide, C2, and absorbent (C3) - then is chilled to condense (24) and recover trace amounts of C2 and heavier gases, including trace amounts of the C3 absorbent (26), at temperatures of about -101 °C (-150 °  F) or higher.

Abstract: A method for collecting volatile organic substances from off-gas containing moisture and volatile organic substances. After the moisture has been removed by a dehumidifying tower filled with moisture absorbent for selectively adsorbing the moisture from the gas containing the organic substances and the moisture, the organic substances  are  adsorbed  and  removed  under  a  relatively  low temperature condition. The organic substances is desorbed under a relatively high temperature condition from the adsorbing tower which is saturated with the organic substances. The desorbed organic substances are liquefied and collected under a low temperature and/or pressurizing condition. The dry gas from which the organic substances have been removed and made harmless  is heated if necessary.          Thereafter, the dry gas is purged in a counter flow manner in the dehumidifying tower which is saturated with the moisture to perform the regeneration of the moisture absorbent and is discharged to the outside of the system together with the desorbed moisture.

Abstract: At a post stage of an amplifying optical fiber, such a means is provided that detects a level of light having a center wavelength of the amplified signal light, and also a level of light having a wavelength different from that of this center wavelength, and further another means is provided which compares the level of the light having these wavelengths, and controls an output of a pumping light source based on this comparison result. To detect the intensity of the light having these two wavelengths, two light branching devices, and light receiving devices are arranged via the respective light band-pass filters for passing therethrough the light having the above-described wavelengths at the post stage of the amplifying optical fiber. When the light intensity ratio of both the light having the wavelengths is larger than a preset value, the output of the pumping light source is maintained.          Conversely, when this light intensity ratio is smaller than this preset value, the output of the pumping light source is interrupted by assuming that the input signal light is interrupted. The adverse influences caused by the light surge can be avoided without increasing the noise figure.

Abstract: A laundry washing machine in which water is conserved by replacing the conventional deep rinse by a series of spray rinses. Each spray rinse utilises a predetermined quantity of water which is sprayed directly at the clothes load while the load is rotated, thereby allowing the rinse water to pass straight through the clothes load, removing soil and/or detergent from the clothes on its way. The amount of water used in each spray rinse is determined from a first "sense rinse" cycle in which the volume of water required to totally saturate the clothes load is found. In each subsequent rinse, a proportion (preferably from about 50% to about 100%) of this value is used.
