Title: Variable ratio transmission control system
Inventor: PERRY FORBES GEORGE DE BRIE
IPC: F16D48/02
Filed: 1961-03-06
Abstract: 1,013,592. Fluid-pressure servomotor systems. NATIONAL RESEARCH DEVELOPMENT CORPORATION. March 6, 1962 [March 6,1961; Nov. 8, 1961], Nos. 8168/61 and 40088/61. Heading G3P. [Also in Divisions B7 and F2] Relates to a transmission system for a motor vehicle, of the type comprising a prime mover, a continuously-variable-ratio friction gear and a clutch connected between the gear and the vehicle road wheels (see Division F2). In one form, ratio shift is effected by the piston rod 18 of a servomotor 21, biased downwardly to a low ratio position by a spring 24 and biased upwardly to a high ratio position when a valve 28 is manually opened to admit oil under pressure from an engine driven pump 13 and a pipe 33 to a pipe 26, and thence to the space below the piston 20 of the servomotor. A vent port 61 in the piston rod 18 passes over a groove 60 in a rod rotated by turning a handle 62. The groove 60 has one straight edge parallel to the rod, and one edge of generally helical configuration. Thus, as the rod 18 moves upwardly, the port 61 passes on to the groove 60, to allow venting of oil through a restriction 63 whence it returns to a sump 37. By turning the handle 62, the axial position of the piston rod 18 and the port 61 relative to the servo housing 21 at which equilibrium is reached may be adjusted. With the handle 62 in a fixed position, the position of the servo piston 20 and the piston rod 18 is dependent upon the pressure in the pipe 33, in turn dependent upon the speed of rotation of the engine driven pump 13. The pressure of the oil in the pipe 33 and hence the ratio established in the gearing is modulated by actuation of a bleed valve 48, connected through cam means, Fig. 5A (not shown), to the accelerator pedal of the engine driving the vehicle. The valve 28 is controlled by a forward-reverse gear shift lever 30, which also controls a valve 28<SP>1</SP> which may be manually opened to admit pressure oil from the pipe 33 to a clutch 5 and a fluid coupling 12 in the transmission system. In one modification, Fig. 11 (not shown); an output driven pump is provided as well as the input driven pump 34, and supplies oil under pressure through a two-way valve when the input driven pump is inoperative for engagement of the clutch 5, &c. Ratio shift is still effected automatically in dependence only upon engine speed and the speed of the pump 13, as modulated by rotation of the handle 62 and the accelerator actuated bleed valve 48. In another modification, Fig. 12 (not shown), in which both input and output driven pumps are similarly provided, a metering valve is provided in the circuit leading to the clutch 5, to limit the torque which can be transmitted therethrough before slipping occurs according, to the ratio established in the gearing.

Title: Improvements in and relating to steam condensers and like tubular heat exchangers
IPC: F28F9/26
Filed: 1938-03-16
Abstract: 511,712. Surface condensers. WORTHINGTON-SIMPSON, Ltd., and JENNINGS, M. March 16, 1938, No. 8169. [Class 64 (iii)] A condenser for condensing the steam arising from the boiling-pans in breweries &c. comprises a rectangular casing having a hinged cover 2, and steam inlet and condensate outlet ports 8, 12 respectively, and containing a removable water-cooled unit mounted on a truck 13 supported on rails 7 and formed by a number of interchangeable tubular sections clamped together by longitudinal bolts 28 passing through the upper and lower headers of the sections. Each header is divided by a central partition 20 into two compartments and is provided on one face with water ports 25 and on the opposite face with spacing bosses 26. The ports of the lower header of the rearmost section are connected to water inlet and outlet ports 9, 10 respectively in the back of the casing. The cooling water flows from the inlet port 9 into the right-hand compartment of the lower header of the rearmost section and thence in an up and down path through the corresponding compartments of the intermediate sections to the right-hand compartment of the front section. The water thence flows into the left-hand compartment of the lower header of the front section and then in an up and down path through the corresponding compartments of the other sections to the outlet port 10. The supply of steam to the casing may be shut off when it is desired to remove the cooling unit by a valve 42, Fig. 5, having seatings 40, 41 and a flange 38 for connection to the steam inlet port 8 in the casing.
Patent GB-397403-A (GB)
Title: Improvements in or relating to matrix-setting and type-line-casting machines
IPC: B41B7/18
Filed: 1933-03-17
Abstract: 397,403. Type-bar-making machines. TYPOGRAPH GES., 17, Huttenstrasse, Berlin. March 17, 1933, No. 8194. Convention date, May 31, 1932. [Class 100 (iii).] Keyboards.-In a power drive for the matrixrelease devices of matrix-setting and typeline-casting machines having the usual eccentric cams 27 which co-operate during the release operation with constantly-driven rollers 5, the keys 1 carry spring blades 22 provided with stops 21 which engage projections 20 on intermediate members 15, which lock the camcarrying levers 12 in their position of rest, so that on the keys being depressed, after the release process has been started, the blades 22 are disengaged from the members 15 and only engage the latter again on the return of the keys to their original position, whereby only one matrix is released at each depression of a key, for however long a period the key is held down. The constantly-driven rollers 5 are carried by shafts 3, 4, of which the shaft 3 is driven by the machine drive, and transmits its rotation to the shaft 4 through the equal gears 9, 10 fixed to the shafts. Normally the cams 27 are held against rotation, when the levers 12 are in their inoperative position, by pins 29 which engage stops 30 fixed to the casing 2, but when a key is depressed, the stop 21 on the spring 22 engages the projection 20 on the arm 18 of the pivoted bell-crank member 15 and rotates it against the action of the spring 19, thereby releasing the end of the lever 12, which turns about its pivot 13 and releases the pin 29 from the stop 30. The disc 27 then engages the roller 5 and is driven thereby until the lever 12 takes up the dotted-line position shown, and so operates the matrix-release wire 11. If meanwhile the key has been released, the member 15 has returned and is in a position to re-lock the lever 12, while the disc 27 continues to rotate until the pin 29 again encounters the stop 30. To ensure that even when a key is depressed for a long time, the release process shall cease after one operation, the blade 22 is disengaged from the member 15, which returns under its spring control, by means of a cylindrical spindle 23 rotatably mounted in the casing ; during depression of the key, the end of the blade 22 encounters the spindle 23 and is bent aside thereby to release the member 15. Should several matrices corresponding to any one key be required in succession, this is effected by partially rotating the spindle 23 to bring a flat surface provided thereon immediately adjacent the spring blade, so that upon depression of a key, the blade is not deflected but continues to engage the member 15 and a matrix is released at each rotation of the spindle 3 or 4 until the key is released. The spindles 23 may be coupled together by links 24, 25 and operated by a single member 26.

Title: Improvements relating to the catalytic desulphurisation of petroleum hydrocarbons
IPC: C10G45/28
Filed: 1950-04-04
Abstract: <PICT:0708244/III/1> Petroleum hydrocarbons are catalytically desulphurized by treatment in the presence of a sulphur-resistant dehydrogenation-hydrogenation catalyst at an elevated temperature and pressure, so that the dehydrogenation of naphthenes contained in the feedstock is effected to provide not more hydrogen than is required to convert organically combined sulphur to hydrogen sulphide and to maintain the pressure in the reaction zone, cooling the vaporous products, separating the liquefied components from the gaseous components, further cooling the gaseous components to form a desulphurized liquid product and a hydrogen-rich gas, and recycling this gas to the reaction zone to constitute the whole of the hydrogen supplied thereto.  The process may be carried out at a pressure of 50-200 p.s.i. and a temperature of 750-800 DEG  F.  The preferred catalyst is cobalt molybdate or mixtures of the oxides of cobalt and molybdenum. The process may be carried out in a static bed reactor or by using a moving catalyst bed or a fluid catalyst.  In an example, treatment of a blend of kerosine, naphtha and sulphur dioxide-kerosine extract is described.  In the drawing, vapours leave the reactor 10 via line 11 and are cooled in a waste heat boiler 13, from where they pass to column 14.  Condensate leaves the base of the column via line 20 and the vapours leaving the column are cooled in cooler 16 or heat exchanged with the feed, and then passed to vessel 17, from which recycle gas is led by line 18 and desulphurized product from line 19 or via line 23 to the top of column 14 to act as reflux.  Part of the vapours from reactor 10 may also be passed direct via line 24 to the base of column 14 as a stripping medium.

Title: Automatic apparatus for determining the hardness of water
IPC: G01N33/18
Filed: 1937-03-30
Abstract: 492,759. Photo-electric apparatus for testing hardness of water. SOC. DES USINES CHIMIQUES RHONE - POULENC. March 30, 1937, No. 9073. Convention date, April 25, 1936.. [Class 40 (iii)] The hardness of water is determined by mixing a measured sample with a definite quantity of soap solution, agitating the mixture with air to form a lather, and, after the mixture has been received in a container having an outlet at the bottom for the escape of the liquid, passing a beam of light through the whole height of the lather in the container on to a photo-electric cell in circuit with an instrument which gives an indication or record whereby the quantity and persistence of the lather may be observed. In the apparatus shown, which is particularly for use in connection with boiler feeding, water falls drop by drop into a vessel 1 from which it is periodically siphoned to a vessel 3, carrying with it, by means of a suction injector 4 a fixed quantity of soap solution which is drawn off from a constant-level bath 5. The mixture passes from 3 to a vessel 6 through a siphon 7, air being drawn in by an injector 8 and forming a lather (if the water is sufficiently soft) which collects in 6. The solution runs away slowly through a small pipe 9. A beam of light from a lamp 11 is passed upwardly through the lather on to a photo-electric cell 12, and the resulting current, amplified if necessary, operates a galvanometer 13 which may be a recording instrument. A warning device, operated through a relay, may be added or substituted for the galvanometer. Specification 485,386 is referred to.
