Title: Improved carbon black dispersions
IPC: C08K3/04
Filed: 1963-02-27
Abstract: A readily-flowable carbon black slurry is prepared without the use of surface-active dispersing agents by (a) dispersing carbon black in a predominantly aqueous medium under conditions of "high shear" in an amount which is sufficient to produce a viscosity of at least 150 centipoises and which is preferably 10-25% by weight of the slurry and (b) subjecting the resultant slurry from (a) to conditions of "mild shear."  "High shear" is defined as that mixing sufficient to produce in a slurry of 7% by weight standard HAF carbon black in water a viscosity of at least 150 centipoises, and "mild shear" as that mixing which is insufficient so to do.  The high shear may be provided for example in a quart Waring Blendor operating at 5000 r.p.m., and the mild shear either in the same Blendor at 3000 r.p.m. or less, or in a peristaltic pump which transports the slurry from the high shear mixer.  The slurry may also contain 10-60 parts oil per 100 parts carbon black.  Rubber masterbatches may be produced by combining the slurry obtained from (b) with latex and coagulating the product.ALSO:Rubber masterbatches are produced by combining with latex a readily-flowable carbon black slurry, prepared without the use of surface-active dispersing agents, and coagulating the product.

Title: Improvements in and relating to brake mechanism
IPC: B60T11/04
Filed: 1929-10-29
Abstract: 347,719. Brake transmitting mechanism. ROCKWELL, E. A. and EVANS, E. R., 1725, Diversey Parkway, Chicago, U.S.A. Oct. 29, 1929, No. 8072/31. Convention date, May 29, 1929. Divided on 346,015. [Class 103 (i).] Transmitting-mechanism whereby greater pressure is applied to the front brakes of a vehicle than to the rear brakes comprises a lever 69 having arms of equal length that are connected respectively by pull rods 61, 64 to the levers 63, 66 of the cams or equivalent of the brakes. The lever 66 is longer than the lever 63 so that with a given turning movement of the lever 69 the lever 66 and its cam receives a smaller turning movement than the lever 63 and its cam, a greater pressure being thus applied to the front brakes. The lever 69 may be actuated from a power device by a lever engaging one arm 74 of an angle lever freely mounted on the shaft 67 of the lever 69, the other arm 72 of the angle lever contacting with an arm 71 of the lever 69 as described in Specification 346,015. The power device may be of the kind in which power is derived from the power shaft of the vehicle, and which thus has itself a braking action on the rear wheels. An emergency pull-rod 79 is connected to the lever 69 in line with the pull rod 64 whereby all the brakes may be applied and also permits application of the rear brakes in the event of breakage of the connections to the front brakes. The Specification as open to inspection under Sect. 91 (3) (a) describes a modification in which the cam levers of the brakes are of equal length and the increased turning movement of the front brake cams is obtained by making the corresponding arm of the lever 69 shorter than that to which the pull rod of the rear brakes is connected. In a further modification the hole through the lever 69 for the shaft 67 is elliptical in shape so that the lever is free to float and an equalized pull is given to the rods 61, 64 but the cam lever of the front brakes is longer than that of the rear brakes, resulting in the application of greater pressure to the front brakes. Further in this arrangement the point of contact between the arms 71, 72 is above the plane passing through the axis of the shaft 67 normal to the longitudinal plane of the arms of the lever 69. This subject-matter does not appear in the Specification as accepted.

Filed: 1957-03-12
Abstract: <PICT:0811086/III/1> A method and device for applying light-sensitive material, usually colloidal, to printing formes or cylinders with avoidance of the presence of dust particles which prevent absolute contact during photo - copying and cause subsequent etching defects, involves lowering the forme or cylinder into a container adapted to receive the solution with what is to form the base of the container attached to the forme or cylinder while providing air filter means closing the space adjacent to the mouth of the container and between the latter and the forme or cylinder. The carrying of dust particles along with air drawn into the container during the lowering is thereby prevented or diminished. In an example described with reference to the similar device of Specification 787,328 the air filter means is constituted by a sealing sleeve 5 encircling a cylinder 3 and resting on the upper edge of container 1 during the lowering of the cylinder with its attached container-base 4, and solution is arranged to be passed from reservoir 16 along tube 18 and through the movable base 4 into the container 1.  An overflow pipe 20 communicates with reservoir 16 and jacket 2 is provided to keep the solution at a specific temperature.  The sealing sleeve 5 may be of filter fabric, foam rubber or synthetic plastic and may consist of several coaxial layers.

Patent GB-722443-A (GB)
Title: Improvements in photographic and x-ray apparatus
IPC: G03B42/02
Filed: 1952-03-31
Abstract: 722,443. Photographic cameras; X-ray apparatus. SERIX, [formerly MIESCH & CIE.]. March 31, 1952 [April 6, 1951; Nov. 28, 1951], No. 8134/52. Class 98 (1). A roll-film photographic camera or radiographic apparatus has a locking device which allows the supply spool to rotate only when it is accurately positioned axially. As shown in Fig. 1, in X-ray apparatus roll-film 3 is fed from a supply spool 17 over a driving roller 15, between a fixed plate 2 and a movable plate 4, and over a second driving roller 16 to a take-up spool 22. The film is driven by a roller 8, rotatable as by a handle 10 or an electric motor and connected by a belt or chain 11 to a roller 7. A roller 9, movable between rollers 7, 8, is normally disengaged but on rotation of roller 7 is urged by a cam 12 thereon into driving contact with roller 8, thus driving rollers 15, 16 to move the film through belts 13, 14, and driving take-up spool 22 through a belt 23 and a slipping clutch. A cam 6 on roller 7 urges plate 4 against plate 2 to hold the film flat between them during the period when roller 9 is disengaged from the film drive. The supply spool lock, Fig. 5, comprises a rotatable sleeve 34 carrying slidable rods 36 with prolonged shanks 37, the heads 38 of which are normally urged by springs into a recess 43. The heads 38 and recess 43 are non-circular and complementary in shape so that sleeve 34 is prevented from rotating. When, however, the supply spool 17 is inserted in the apparatus the stepped end of its spindle (shown in broken lines) engages rods 36 so that heads 38 are pushed out of recess 43 into a recess 44 large enough to allow rotation. The presser plate 4 is carried by linkages 5 provided with springs, may be coated with luminescent material, and may be interchangeable with other plates. It may also have vertical members 30, Fig. 3, connected thereto by cross-bars 31 and springs 32. When the plate is advanced members 30 first engage the edges of the film, the springs yielding as the plate advances to press the whole exposure area. Pressure rollers 49 hold the film against the driving rollers 15, 16. The film is fed over a guiding roller 24 to the take-up spool 22 in a compartment 26, which may be closed by flexible metal screens 50 and removed after the exposed film has been wound on. When a backing paper 3 is supplied with the film, it is fed by its own route to the take-up spool. When the exposed film is not spooled, a trap 25 supporting the guiding roller 24 is raised and a cutter blade 27, operated by a link 28 connected to roller 7, cuts off exposed lengths of film which fall into cornpartment 26. In an alternative embodiment the pressure plate is carried by pivoted arms rooked by cams, a removable oscillatory film cutter is used, and a Geneva mechanism winds the film.

Title: Improvements in apparatus for testing the balance of rotary bodies
IPC: G01M1/12
Filed: 1924-03-31
Abstract: 227,021. Marks, E. C. R., (Toledo Scale Co.). March 31, 1924. Testing balance of rotary apparatus. - Comprises a device for static balancing fitted with counterbalancing mechanism adapted to indicate the amount of material to be added or subtracted to balance the body, and a balanced lever for connecting the body to the. counterbalancing mechanism. The base plate 1 has screwed to it a plate 4 which receives the ends of two guide rods 3 the other ends of which are secured to uprights 2. Fixed to the plate 4 are two uprights 6 furnished with antifriction bearings for two shafts 7 carrying overlappina discs 8. Two uprights 10 mounted on a carriage 9 adapted to slide on the guide rods 3 carry in a similar way overlapping discs 14, the tops of the uprights 10 being vertically adjustable. The shaft of the rotor to be balanced is supported on the two pairs of discs 8, 14, the adjustablity of the carriage 9 accommodating different lengths of rotor while the adjustability of the uprights 10 accommo-- dates a rotor having its ends of different' diameters. The rotor is positioned axially by a spring finger carried on a lever 50 pivoted to a lug on a standard 46 which is also adjustable vertically and along the guides 3. Notched arms 70 connected to a shaft 71 journaled in extensions on uprights 6, 11 take under the rotor shaft and are moved by, a cam 73 and crank 74 to lower the rotor gently on to the discs. One arm is angularly adjusted relatively to the shaft 71 to accommodate a shaft with ends of different diameter. The rotor is placed on the discs and allowed to rock into a position of equilibrium under the influence of gravity. The " light point " is then on top. This point, is marked by a spring plunger 27 carried by an arm 23 swing- ing about a post 19. The plunger normally engages an inking pad but can be swung over the " light part " to mark it and to clamp the armature in this position. An arm 66 balanced about a hole in its centre is now placed over the end of the shaft and is located with its cone 67 against a stop 62 on a pivoted lever 60 which is in raised position. The raising of the lever through the stop 63 positioning a stop 64 to locate the arm axially on the shaft. The arm 66 is then clamped to the shaft and the plunger 25 and lever 60 moved back to initial position. The cone 67 is then placed in a stirrup 41 connected by a flexible ribbon 38 to a segment on a pendulum swinging about a knife edge bearing 36 carried by a framework 35. The pendulum has a light pointer 39 moving over a scale 40 graduated to indicate the number of metal slips to be inserted in the slots between the poles of the armature at the " light point " in order to effect balance. The scale plates 40 and the arms 66 are interchangeable with others suitable for different sizes of armature, and the framework 35 is adjustable on the base plate accordingly. Charts are also prepared for metal strips of different sizes. In a modification the discs 8, 14 are themselves carried on overlapping discs to minimize friction.

Abstract: 791,545. Transistor two-stable state circuits. MULLARD RADIO VALVE CO., Ltd. March 26, 1956 [March 23, 1955], No. 8453/55. Class 40 (6). In a bi-stable state circuit as described in Specification 767,727 in which a transistor T1 with D.C. conducting loads Re, Rcl is D.C. coupled to the base of a second transistor T2 in turn back-coupled over D.C. conducting impedance Rx between the emitters, a single pulse source P is effective over diodes D1, D2 to feed pulses to trigger and reset the circuit. One of the triggering points el is within the feed-back loop and square-wave steering voltages are applied to the diodes derived from the collector C2 and the collector of auxiliary transistor T3, the use of which permits a higher switching speed. With transistor T1 on and T2 off, diode D1 has a large negative bias and due to the common emitter coupling transistor T3 is on so that diode D2 passes a pulse through capacitor C5 to emitter el to cause transistor T1 to pass to the off state. Since the state of transistors T2, T3 is reversed, the next pulse P passes through diode D1 and capacitor C4 to the base of transistor T1 to restore the circuit to its initial state with transistor T1 conducting. In a modification, Fig. 2 (not shown), the transistor T3 is arranged with an earthed emitter connection and phase-reversal is affected by a resistor potential divider between the collector of transistor T2 and a fixed point with a tapping on the divider connected to the base of transistor T3. Specification 791.544 also is referred to,
