Title: Turbo power transmitter
IPC: F16D33/06
Filed: 1961-03-09
Abstract: 912,698. Hydraulic couplings and torque converters. VOITH G.m.b.H., J. M. March 9, 1961 [March 26, 1960], No. 8705/61. Class 69 (2). An hydraulic transmitter, such as a coupling or torque converter comprises a control member 55, Fig. 1, actuated by a non-positive connection which is between the two rotary parts 56, 59 of the transmitter and is directly responsive to the reversal of the direction of slip in the transmitter, the control member being adjusted into a transmitter emptying setting where the secondary part overruns the primary part and into a transmitter filling setting when the secondary parts lags behind the primary part. The control member consists of a rotary slide 55, constituting the output shaft of the secondary part 56 and connected thereto by an arcuate recess 57 receiving a pin 58 on the secondary part. The supply from an inlet port 67 is connectable to either of passages 65, 66, the other passage being connected to an outlet 68, so that the transmitter is operable in either direction of rotation 73, 74. The output shaft, when it overruns the primary part 59, moves relative to the secondary part 56 an amount determined by the pin-and-recess connections 57, 58 to connect a filling passage 60 to the outlet 68, the transmitter being emptied through ports 61. In another embodiment, the shaft of the secondary part 80, Fig. 3, is extended into a sleeve 82 having ports 81 and receiving a slide 83 which is formed with a curb 84 defining chambers 85, 86 and is rotatable relative to the primary part 92 through an angle of approximately 90 degrees as determined by a pin 88 engaging the ends of an arcuate recess 89 in the part 92. An inlet port 99 is connectable by movement of a valve 98 to either of passages 100, 101 depending upon the direction of rotation 109 or 110 of the transmitter. With the secondary part 80 lagging behind the primary part 92, the passage 100 or 101 connected by the valve 98 to the inlet port 99 is connected by one or other of the chambers 85, or 86 to a filling passage 90, the other passage 101 or 100 being connected to an outlet 102 or 103. When the secondary part overruns the primary part, the slide 83 is moved to disconnect the passage 100 or 101 from the filling passage which is then connected to the outlet, the transmitter rapidly emptying through valves 105 responsive to the drop in pressure in the filling passage. The valve 98 can be moved to other positions wherein the coupling is maintained full or empty irrespective of the direction of rotation and the condition of slip in the transmitter.

Abstract: 1442039 Counterbalancing WHESSOE Ltd 24 Feb 1975 [26 Feb 1974] 8719/74 Heading B8B A system for counterbalancing a liquid loading arm 1 mounted for rotation between an upper and a lower position about a horizontal axis 3, comprises a bracket 17 non-rotatable about the axis 3, a single acting hydraulic ram 8 connected between the arm 1 and the bracket 17 such that fluid is displaced from the ram as the arm is moved from the upper to the lower position, and a gas accumulator 10 for receiving fluid from the ram and for increasing the pressure of the fluid in the ram in response to said displacement of fluid. The gravitational torque generated by the ram 1 about the axis 3 is balanced by the torque of the ram system 7. The ram cylinder 11 is pivotal at 12 to a bracket 13 on the arm 1, and the ram piston-rod 14 is pivoted at 16 to the bracket 17, whereby as the arm 1 is lowered, fluid is displaced from the ram 8 through conduit 9 to the gas accumulator 10 which provides increased resistance to the fluid as the gas is further compressed as the arm 1 moves lower, this increased resistance increasing in proportion to the increased torque generated as the arm 1 is lowered. A valve is provided to facilitate addition to or removal from the ram of hydraulic fluid, to adjust the balancing force produced by the ram. In addition, a manually operable volume compensator may be included in the hydraulic system so that the balance unit may be adjusted to take account of changes in ambient temperature.

Abstract: 1329097 Reforming-regeneration apparatus UNIVERSAL OIL PRODUCTS CO 18 Sept 1970 [25 Sept 1969] 9272/73 Divided out of 1329096 Heading B1F A multiple-stage reactor-regenerator apparatus for use in reforming hydrocarbons comprises two vertically spaced reactor vessels 5, 11 each containing an annular (non fluidised) catalyst bed 6, 13. The catalyst bed moves slowly downwardly from inlet 60 to inlets 19, 20. A hydrocarbon stream to be reformed, is heated in heater 2 and then is passed into the upper reaction vessel whereupon it firstly heat exchanges at 61 with fresh incoming catalyst. The hydrocarbon stream then passes through the upper catalyst bed from the outer annular inlet zone to inner outlet zone 8. The partially reformed stream is then withdrawn at 9 and passed through a heater 10 before being passed into the second and lower catalyst bed. Reformed hydrocarbons are withdrawn at 15. Spent catalyst is lifted by line 27 to a hopper 28 from whence it falls through a regenerating apparatus comprising a vessel 31. The catalyst is subjected first to a decarbonisation, then to a chlorination in zone 32 and is then dried in zone 33 before being returned via line 60 to the reactor. Flue gases from the decarbonisation zone are withdrawn at 36 and recycled to the zone at 44 after removal of halogen and oxides of sulphur in scrubber 37 where they are treated with a caustic stream. Excess steam and chlorine withdrawn from the chlorination zone at 50 is recycled to a lower part of the zone at 46. Specification 1329096 describes and claims a continuous reforming regenerating process using the above apparatus. Specification 1329098 describes and claims the regeneration apparatus.

A method propagating yeast includes the steps of preparing a culture medium, aerating the medium and introducing ozone into the medium. The culture medium may be prepared from hydrolyzates of plant tissues or hydrocarbons of the n-paraffin series, and the ozone introduced either with air employed during the preparation of the medium (between 10<SP>-2</SP>% and 1À5% ozone by volume of ozone-air mixture) or with the air employed for aerating the medium during the propagation of the yeast (10<SP>-6</SP>% - 1À5 x 10<SP>-4</SP>% by volume ozone). Hydrolyzates of plant tissues: Ozone reduces the concentration of such inhibitors of yeast growth as furfural and hydroxymethylfurfural, and coagulates physiologically active colloids. Hydrocarbons of the n-paraffin series: Treatment at a temperature of 100‹C. with an ozone-air mixture oxidizes the terminal groups of the n-hydrocarbons to give organic acids. Cyclic hydrocarbons, if present, are also oxidized.
