Title: Carbon black process
IPC: C09C1/48
Filed: 1970-01-30
Abstract: 1300862 Carbon black PHILLIPS PETROLEUM CO 30 Jane 1970 [31 Jan 1969] 4636/70 Heading C1A In the preparation of carbon black by decomposing a hydrocarbon feed in a reaction zone, there is added to the zone an additive which modifies one or more properties of the carbon black produced, this additive is introduced into the zone at a temp. above its m.p. and is a mixture of at least two compounds, both of which are solid at room temperature, and which together or individually have the desired modifying effect, said mixture being such that its m.p. is less than those of its individual components. The additive preferably modifies the structure of the black, and is such that at least one component, preferably at least two components, are capable when each is used alone, of modifying the structure of the carbon black. The property modifying components may be alkali metal having an atomic no. of at least 19 or compounds of such alkali metals, e.g. oxides of Na or K; or salts of Na or K with nitric acid or nitrous acid. Thus the mixture may contain two or more of KNO 3 , KNO 2 , NaNO 3  and NaNO 2 . The mixture preferably has a m.p. less than 600 F. The mixture may be added e.g. in the form of an aqueous solution to the hydrocarbon feed which is heated to the desired temp. before introduction to the reaction zone.

Title: Improvements in or relating to brick cutting machines
IPC: B28B11/16
Filed: 1948-02-18
Abstract: 650,066. Variable-speed control. QUEENSMERE PROPERTIES & INVESTMENTS, Ltd. Feb. 18, 1948, No. 4764. [Class 80(ii)] [Also in Group V] An arrangement for co-ordinating the speed of a moving cutting-wire 38 in a brick-cutting machine (see Group V) with the speed of a travelling column of clay through which the wire cuts is disposed as follows:-The wire is moved by a shaft 56 via pulleys 62, 64 and jockey loaded belt 60, shaft 58, gear box 84 and other connections. The shaft 58 carries a worm 68 meshing with worm wheel 70 on shaft 72 which carries a worm wheel 74 meshing with worm 76 on a shaft 78. Shaft 78 carries a disc 80 which bears in driven relationship against the face of a disc 82 driven by the rear roller 16 of belt 14. Belt 14 receives the clay column and is frictionally driven thereby. The clay column thus drives worm 76. Belt 60 tends to drive worm wheel 74 at a certain speed, but worm wheel 74 is restrained by worm 76, the speed of which is governed by that of the clay column. Belt 60 therefore slips to an extent governed by the clay column speed. This belt may be replaced by a non-slipping V-belt or chain running over sprockets, in which case a slipping clutch, preferably a hydraulic coupling, is used. The disc 80 is splined on the shaft 78, and by adjusting the disc radially the length of the pieces cut from the column is adjusted.

Patent GB-676040-A (GB)
Title: Improvements in and relating to typographical line-composing machines
IPC: B41B15/08
Filed: 1950-03-01
Abstract: 676,040. Photographic type composing machines. INTERTYPE, Ltd. March 1, 1950 [March 11, 1949], No. 5172/50. Class 98 (i). [Also in Group XVI] In a photographic type-composing machine of the general construction described in Specification 590,553, a control member is provided co-operating with the driving means of the elevator which transports the matrices to a distributing station, and adapted to arrest the elevator at a predetermined position between the matrix-receiving and distributing stations, whereby the line of matrices is held stationary for identification. The control member arrests the elevator only if the composition of a succeeding line is unduly delayed. An additional pawl 20, Fig. 3, is provided on the linedelivery cam 7, which acts on the lever 8 to disengage the clutch and stop rotation of the cam-shaft 1 after about 265 degrees, when the elevator is at the predetermined identification position. At the same time the lug 37 closes an additional switch 29 in the circuit of the solenoid relay 26 for causing engagement of the clutch, in series with a control switch Z, Figs. 9 and 11, the arrangement being such that if the switch Z is closed before the pawl 20 reaches the lever 8, the relay 26 acts on arm 15 of lever 10, which deflects pawl 20 so that the elevator is not arrested. Actuation of either of the word-space keys 41, 42, Fig. 9, raises a vertical rod 60, Figs. 9 and 11, and closes the normallyopen switch Z. When the key is released, the switch remains closed, being pivoted at 64 between friction washers. If a word-space key is actuated in composing a line before the pawl 20 becomes operative, the elevator is therefore not arrested. When the line assembler C is raised for delivery of the completed line to the character-reproducing station, the switch Z is opened by means of a lever 66 and bar 69. When either key 41, 42 is depressed, a further key lever 55 or 57 is also actuated, by means of a lug 52 or 53 on a portion of a member 49 mounted on the shaft 43. According to the longitudinal position of the manually-operated member 49, the key lever 55 is actuated to release a thin spacer element of fixed thickness from the magazine A, or the lever 57 is actuated to release a thick spacer element. Specifications 14582/90, [Class 100], and 568,929 also are referred to.

Title: Improvements in or relating to apparatus for handling continuously-cast rod
IPC: B22D11/126
Filed: 1943-04-02
Abstract: 562,829. Casting and sawing rod &c. DOEHLER DIE CASTING CO. April 2, 1943, No. 5310. Convention date, March 19, 1942. [Class 145 (ii)] [Also in Group XXII] Apparatus for handling rod, tubing, &c. 1 from a continuous casting-machine comprises a pivoted cradle 8 to receive a length of rod and means for cutting off this length and for discharging it by tilting the cradle, these operations being initiated by the moving rod. The control means may comprise two co-operating members, of which one tilts with the cradle and the other does not. The rod I may be delivered from a casting-machine as described in Specification 561,363, [Group XXII], by rolls 2 until its end engages a catch 12 thereby releasing a disc 13, which is weighted at 14, is pivoted at 113 to the cradle and carries earthed electric contacts 16, adapted to engage contacts 17 fixed. on the cradle. The swing of the weight 14 thus causes the circuits 18, 24 to be closed, the former momentarily to energize a solenoid 19 and operate the valve 120 of a motor 20, so that this moves a slide 21 to the left to release the grip of roller 2 and thus stop the rod feed, advance the saw 22, and finally close a switch 25. The circuit 24 drives the motor 23 of the saw. When the rod is severed, the switch 25 is closed to energize solenoids 27, 28 to reverse the motor 20 and start a motor 29 to turn the cradle in a clockwise direction about its pivot 9. As the disc 13 does not rotate with the cradle the circuit 24 is broken, thus stopping the motor 23, and, as the cradle reaches the discharge position, contacts 16a, 17a, Fig. 5, are closed and as soon as the rod is discharged it allows a switch 10 to close so that a circuit 32 is completed through a solenoid 33 to reverse the motor 29. Meanwhile, the return of the slide 21 has allowed the switch 25 to open and the rolls 2 to close and restart the casting of the rod 1. During the return of the cradle 8 the catch 12 re-engages the disc 13. A pawl 31 prevents the severed rod from retrograde movement.

Filed: 1977-02-09
Abstract: 1534233 Frequency/phase comparators BENDIX CORP 9 Feb 1977 [2 March 1976] 05353/77 Heading H3A In a frequency/phase comparator suitable for use in a phase locked loop type of frequency synthesizer (Fig. 1, not shown) and employing a pair of preconditionable, resettable memory elements 20', 21<SP>2</SP> respectively receiving as clock pulses, the two signals FA, FB being frequency compared and providing output, pulses on one of two output lines in dependence of the relative frequency difference for application to an integrator, two additional memory elements 26, 27 respectively preconditioned by the output of 20', 21' and clocked by the same signals FA, FB are provided so that the combined outputs of 20', 26; 21', 27 are effective for input frequency ratios greater than 2:1 to provide a substantially steady non-zero output on one of the output lines facilitating rapid synchronization of the loop to a selected frequency. For frequency ratios of two or less the comparator provides pulsed outputs on one of the output lines and at phase and frequency equality the output on both lines becomes zero. The memory elements may be D type bistable flipflops. In operation, that bistable (20' or 21')  receiving the greater of the two frequencies produces a pulse which is terminated at the appearance of the lesser frequency signal when both bistables are reset via a NAND gate 22.

Title: Improvements in or relating to the treatment of barium peroxide for obtaining peroxide of hydrogen and an improved "blanc fixe"
IPC: C01B15/032
Filed: 1925-03-02
Abstract: 252,768. Weber, I. E., Laporte, Ltd., B., and Alcock, H. E. March 2, 1925. Hydrogen peroxide; phosphoric acid.-Barium peroxide is decomposed by means of commercial phosphoric acid, the precipitated barium phosphate, after separation and washing, is dissolved in more phosphoric acid and the undissolved impurities, such as carbon particles removed by filtration. The filtrate, preferably after heating to 60-80‹ C., is then precipitated by means of sulphuric acid in order to obtain " blanc-fixe " and phosphoric acid for re-use. It is found that the purity of the phosphoric acid increases with each cycle so that the hydrogen peroxide is only contaminated by any impurities present in the barium peroxide. The " blanc-fixe " being produced from a purified barium phosphate, is of good colour and quality. When alkali phosphate, for example sodium phosphate, is required, alkali sulphate may be used in place of the sulphuric acid. It is stated in the Provisional Specification that any acid or salt which gives an insoluble barium salt may be used for decomposing the barium peroxide and any acid or salt may be used for dissolving the resulting barium precipitate.
