Title: New or improved means for mixing small quantities of chemicals or other materials
IPC: A61C5/68
Filed: 1949-08-18
Abstract: 664,977. Mixing dental stoppings. CHADWICK, S. E., and WHYLEY, L. F. Aug. 18, 1950. [Aug. 18, 1949], No. 21458/49. Class 81 (ii). [Also in Group II] A device for mixing small quantities of chemicals or other materials comprises a mixing chamber mounted on the free end of a stem or shank projecting from a spherical head which is free to oscillate in a-complementary bearing or socket in a housing but is held against rotation about the axis of the stem or shank and which is coupled by an eccentric driving member. to a spindle adapted to be driven by any convenient means. As described for a device adapted to be driven by the flexible shaft of a dental engine and for mixing amalgam or other dental filling materials, an enlarged cylindrical portion d of a rotatable spindle e is formed with an eccentric recess n and is carried by a handle a adjacent to a spherical head g; the spherical head having a rearwardly extending pin m which engages the recess n and a forwardly extending screwed stem p to which a mixing chamber is attached by an arm q. The spherical head g is held between spherically recessed surfaces in the handle and in a cap j and has transversely extending pins k engaging diametrically opposed slots b in the spherically recessed part of the handle, the arrangement being such as to allow oscillation of the spherical head by the drive of the eccentric recess n, but to prevent its rotation about the axis of the handle. The mixing chamber r is thereby swung around in a substantially circular path. For laboratory or other use the device may be mounted on a base or stand and driven by an electric motor either directly or through a flexible shaft or gearing.

Title: Process for the simultaneous catalytic cracking of dissimilar  hydrocarbon feedstocks
IPC: C10G11/18
Filed: 1971-04-19
Abstract: 1345912 Cracking hydrocarbon oils ESSO RESEARCH & ENG CO 19 April 1971 [19 March 1970] 21469/71 Heading C5E At least two dissimilar hydrocarbon feedstocks are cracked simultaneously by (a) contacting each in a separate fluidized reaction zone with a cracking catalyst from a common regenerator, at least one reaction zone being a transferline, (b) passing the effluent from each reaction zone into a segregated section of a separation zone, (c) separately recovering hydrocarbons from each section of the separation zone and returning catalyst from each to the common regenerator by a common conduit. Each cracking zone may be a transferline. Preferably the catalyst from each separation section is sepa rately stripped, the stripped gases combined with the effluent from that separation section, and each effluent separately fractionated. As shown, fresh gas oil is supplied at 101, make-up catalyst at 102 and mixed with regenerated catalyst in transferline 103. The effluent is separated in compartment 104, the catalyst is stripped at 114 and returned by line 116 to regenerator 117. The effluent and stripped gases are taken off by line 107 and fractionated into light ends, gasoline, jet fuel (320‹ to 520‹ F.) and a residual fraction which is returned by line 108. This feeds it to riser 110 containing catalyst from the regenerator. They react in the riser, which discharges into a dense bed 111, where the reaction continues. Spent catalyst is stripped at 115 before returning to the regenerator by conduit 116. The effluent and stripped gases are taken off by line 113 and fractionated to provide light ends, gasoline, kerosine (320- 420‹F.) or jet fuel, a two-ring aromatic fraction (420-500‹ F.), a 500-650‹ F. recycle oil, a three-ring aromatic fraction (650-700‹ F.) a 700-800‹ F. recycle oil and a heavy bottom fraction. The two recycle oils are returned by line 109, and join the recycle in line 108. Valves are provided so that the effluents from both cracking zones can be fractionated together if preferred, but separate fractionation permits a better jet fuel to be recovered. In another embodiment (Fig. 1, not shown), the second transferline discharges into a second separating zone like that of the first, instead of into a dense bed. The catalyst may be a molecular sieve in a siliceous gel matrix, or silica-magnesia.

Title: Process of and apparatus for transforming elementary atoms
IPC: B01J19/08
Filed: 1925-08-28
Abstract: The transformation of metallic atoms is effected by subjecting small quantities of the metal in a vaporizing chamber to high pressure and temperature and submitting the separated metal vapour to the electrostatic or electrolytic effect of strong, preferably direct, electric current.  A thin filament of metal may be placed in a duct in a massive block of quartz, granite or other refractory mineral insulating substance, the ends of the filament being clamped between two thick metal plates which carry terminals and act as closures for the dust.  The heating may be effected by a current of low voltage and high amperage, a separate current of very high voltage, supplied to large-surface electrodes in the vaporizing chamber, being used for the electrostatic or electrolytic effects.  The high-voltage circuit may include a Crooke's or Geissler's tube.  For testing metals on a large scale, metallic vapour may be introduced through a valve into the space containing the electric arc.  The process may be used for the production of radium, mesothorium, uranium X and thorium X from uranium or thorium, or for transforming mercury into gold.

Title: The manufacture of poly-halogenated fatty acids
IPC: C11C3/00
Filed: 1929-07-15
Abstract: 336,623. Carpmael, A., (I. G. Farbenindustrie Akt.-Ges.). July 15, 1929. Halogenated higher fatty acids.-Saturated or unsaturated fatty acids containing more than eight carbon atoms in the molecule, and which may contain hydroxy groups, are treated with halogens or a mixture of a chlorate and hydrochloric acid, whereby at least three halogens enter the molecule, one at least of which replaces a hydrogen atom by substitution. According to examples, trichlorinated-, tetrabrominated- and hexachlorinated-ricinoleie acid and a trichlorinated oleic acid are thus' obtained by direct halogenation. A pentachlordihydroxystearic acid is also obtained by direct treatment of the parent substance with chlorine. In further examples, a solution of ricinoleic acid in carbontetrachloride is treated with chlorine, while cooling, until a product contaning 16 atoms of chlorine in the molecule is obtained. A heptachlorinatedricinoleic acid, a tetrachlorinated oleic acid and a hexachlorinated stearic acid are similarly obtained, using carbon tetrachloride solutions' of the parent fatty acids. The chlorination of stearic acid, by suspending the latter in aqueous sodium or potassium chlorate and introducing gaseous or aqueous hydrochloric acid is also referred to. The products are oils, generally having adhesive properties, or plastic or resinous substances.

Title: Improvements in hydraulic braking systems
Inventor: REYNOLDS DESMOND HENRY JAMES
IPC: B60T11/34
Filed: 1965-05-22
Abstract: 1,142,855. Valves. GIRLING Ltd. 20 May, 1966 [22 May, 1965], No. 21768/65. Headings F2F and F2V. A valve 1 in or for a vehicle braking system having a source M of pressurized fluid and a line R leading therefrom to a wheel brake has internal means 13 arranged to respond to an initial predetermined rate of fluid flow to close a normally open passage 2, 11 through the valve and to respond to a predetermined increase in fluid pressure from the source to reestablish fluid communication through the valve, a pressure drop being then created across the valve. Initial flow from the master cylinder passes around the piston 13, which is a clearance fit in its bore 3, and then through the passage 11 in the plate valve 7, 8 to the outlet 5. When the flow is sufficient the piston 13 moves leftwards against spring 14 to abut valve 8 and close off passage 11. At a predetermined inlet pressure the preloaded spring 9 is overcome and the plate valve 7, 8 moves leftwards to allow flow around the piston and past valve seat 6, the outlet pressure being rendered less than that at the inlet by the effect of spring 9. The arrangement permits full recuperation when the brakes are released and is applicable to a vehicle having front disc brakes supplied from outlet 5 and rear drum brakes supplied directly from the master cylinder M. In a modification, the piston is replaced by a cup-shaped member having a headed stem which extends through passage 11 and provides a stop for rightward movement of that member. A light spring is provided between the valve plate and the cup-shaped member to hold it clear of the face of member 7 until fluid flow creates a pressure difference to move that member into engagement with the plate.

Abstract: 1434833 Soldering SIEMENS AG 8 May 1973 [2 June 1972] 21785/73 Heading B3R [Also in Division H2] A wire 1 to be connected to an electrical component by soldering is provided with a loop 3 in one end of the wire, and the loop is temporarily enveloped in a body of liquid solder whereby a quantity of solder is retained thereon which closes up the loop and solidifies to form a solid film, the area of the loop being such that the amount of solder in the film is sufficient for soldering the wire. A loop may be provided at each end and filled with solder and the loop may be rectangular. Wires 1 Fig. 5 having insulated looped ends 3 are carried on a movable belt 11 over a flux, e.g. colophony, spraying nozzle 15, then over a wave soldering bath 17 where the insulation is melted and the loops are filled with solder and then over a heated-flux spraying nozzle 15. The treated wires are then brought to a station 19 to which ceramic substrates 21 are supplied. When the looped ends lie opposite contact points 24 on a substrate a photoelectric device causes a U-shaped resistance heated element 25 to bear against the looped ends and melt the solder carried by the ends. When the element 25 is raised a fan cools the soldered joints and the substrate is moved in a direction normal to the belt to withdraw the wires from the belt.

Abstract: 597,777. Magazine gramophones. PAILLARD & CIE. SOC. ANON., E. Aug. 27, 1945, No. 21916. Convention date, Sept. 8, 1944. [Class 40 (ii)] In a record-selecting device in a magazinegramophone, the recordsare supported at the edges by rotatable supports 7, which are rotatable about axis 6 and which have eccentric cams 8 engaging a bridge-member 9 having a depending pin 11 which passes through all but the lowermost record a, whereby during rotation of the supports 7 and cams 8 the lowermost record a is released, but the remainder b, c, &c. rest on the top end of the turntable-spindle extension 3 owing to the sideways displacement of the bridge-member 9 by the cams 8. The depending pin 11 is provided with a ramp 13, the upper edge of which is in a plane corresponding to that of the upper surface of the lowest record when same is of the thickest type, while the lower edge corresponds to that of the upper surface of the lowest record of the thinnest type. In the event of the lowest record being of the thickest type, the ramp 13 during displacement of the bridge-member 9, rides over the surface of the record and bends it down slightly before release, but in the event of the lowest record being of the thinnest type, the next record of the pile will be displaced sideways when contacted by the pin 11, even should both the first and second records together be no thicker than a thick record, thus only allowing the lowermost record to be released. To facilitate loading, the spindleextension 3 is made telescopic and is extended, in the absence of the pin 11, by an internal spring. The minimum length of the extension 3 when under compression is such that the upper end is level with the upper surface of the lowermost record of the thinnest type. The extension 3 may also be mounted on a ball stop to avoid rotation when the pile of records rests thereon.

Abstract: 1,189,954. Double hinges. DAIMLER-BENZ A.G. 9 May, 1968 [10 May, 1967], No. 22064/ 68. Heading E2F. A hinge comprises a first hinge leaf 3 adapted to be connected to a door post 1, a second hinge leaf 10 adapted to be connected to a door 9 and an intermediate piece 5 interconnecting the two hinge leaves and being connected to each hinge piece to form two pivoting axes, A and B, for the hinge. In the intermediate piece 5 is arranged a sliding locking bar 12 which guided by a pin 11, the sliding of the locking bar during movement of the door 9 being brought about by curved control surfaces 15 and 16, which terminate in notches 13 and 14 respectively. Figure 2 shows the position of the hinge after a pivotal movement of the door through 180‹ from the closed position. This occurs about the pivotal axis A since the locking bar 12 engages in the notch 14 of the hinge leaf 10 and consequently the intermediate piece 5 and the hinge flap 10 pivot as one member. At 180‹ the stops 2 and 6 strike each other and beyond this pivotal movement takes place about the axis B. On closing the door, pivoting from 270‹ to 180‹ is about the axis B whereafter the lug 7 abuts against the hinge leaf 10 and further pivoting occurs about the axis A.
