Title: Improvements in the manufacture and production of vat dyestuffs of the dibenzanthrone series
IPC: C09B3/26
Filed: 1926-12-13
Abstract: 286,602. I. G. Farbenindustrie Akt.- Ges. Dec. 14, 1925, [Convention date]. Divided on 262,819. Halogen- or methyl-dibenzanthrones are obtained by treating with alkaline condensing agents Bz1 : Bz1<1>-dibenzanthronyls containing halogen or methyl groups but not substituted in the 2- and 2<1>-positions. The reaction proceeds readily with alcoholic potash at temperatures slightly over 100‹ C. The products so obtained from halogen Bz1 : Bz1<1>-dibenzanthronyls differ in shade from those made by alkaline condensation of the appropriate halogen benzanthrones or halogen 2 : 2<1>-dibenzanthronyls and are also obtained in better yield. According to examples, (1) Bz2 : Bz2<1>-dimethyl - Bz1 : Bz1<1> - -dibenzanthronyl is heated with ethyl-alcoholic potash at 120-130‹ C. ; (2) 6 : 6<1>-dichlor-Bz1 : Bz1<1>-dibenzanthronyl is heated with caustic potash and aniline or ethyl alcohol; the product differs in dyeing proportions from that obtained from 6- chlorbenzanthrone bv the usual method. Bz2 : : Bz2<1>-Dimethyl-Bz1 Bz1<1>-dibenzanthronyl is obtained by treating with acid oxidizing agents the Bz2-methylbenzanthrone obtainable by condensing anthrone with alpha-methylacrolein. alpha-Methylacrolein is obtained by saponifying its dimethylacetal with dilute sulphuric acid. 6 : 6<1>-Dichlor-Bz1 : Bz1<1>-dibenzanthronyl is obtained by the oxidation of 6-chlorbenzanthrone.

Filed: 1924-03-18
Abstract: 220,924. Allmõnna Ingeni÷rsbyran H. G. Torulf. Aug. 22, 1923, (Convention date] Addition to 200,090. Open pan sintering apparatus. - A modification of the means for sintering pulverulent ores as disclosed in the parent Specification comprises a row of working positions 105, 106, &c. at the side of the exhauster house 102 to receive the portable sintering vessels, a transport way 121 extending along said row to an emptying place 104 to carry a transport wagon 124 to and fro, a charge-filling device 101 near the transport way and a device 125 for transporting the sintering vessels from the working position to the transport wagon and back again. Fig. 1 shows a side elevation and Fig. 2 an end elevation. In operation, when the charge in any vessel is sintered, the crane 125 places it on the wagon 124, which is run out to the emptying place 104, where the charge is tipped out, the wagon and vessel are returned and arrested under the chargefilling device 101, where the vessel receives a fresh charge from the mixer. The wagon is moved to the side of the working position where the crane 125 places the sintering vessel in position on its suction box. The igniter 120 is then moved up, the charge is ignited, and allowed to sinter. The crane 125 may be dispensed with provided the way 121 is at a suitable level so that the sintering vessels with wheels on them may be run sideways direct on to the wagon 124. In a modification as shown in Fig. 4, a completely sintered charge in one of the vessels 205 is lifted by the crane 225, run out, and tipped as before. The crane brings back the empty vessed, places it on a wagon 224, picks up a fully charged vessel from the wagon, and places this on a working position on the suction box. The empty vessel on the wagon 224 is brought under the charging hopper 201 recharged, and run back on rails to the vessel-exchanging position as shown. The bottom of the shoot down which the sintered material is tipped is a sieve so that unsintered material passes through the sieve and is separated from the sintered material.

Title: Bistable Trigger Circuit Comprising Two Relatively Complementary Outputs and Two Inputs and a Clock Pulse Input.
IPC: H03K3/037
Filed: 1967-02-14
Abstract: 1,177,572. Shift registers; electronic counters. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 14 Feb., 1967 [17 Feb., 1966], No. 6932/67. Headings G4A and G4C. [Also in Division H3] A bi-stable circuit arrangement of the master and slave type and suitable for use in counters and shift registers is formed from logic circuits and has a binary data input terminal D which, when the input to a further terminal V is "0" does not affect the state of the circuit but when V is "1" causes the circuit, at the next timing pulse Sp, to be set to the state corresponding to the data. The arrangement, called a "DV flip-flop," is compared with the conventional "JK flip-flop". If one output is coupled back to the D input the circuit state is reversed by each timing pulse provided a "1" is present at the V input and the circuit thus performs the T-function (Fig. 3b, not shown). If a "1" is permanently applied to the V input, the circuit reverses whenever a pulse is applied to the nominal timing pulse input terminal Sp. The basic (DV) circuit may be formed from eight NAND circuits (Fig. 1a) which provide an intermediate store Nd2, Nd6 which is set during the timing pulse and an output store Nd4, Nd8 which is set by the intermediate store when the timing pulse terminates. With a "0" at V, neither input gate Nd1, Nd5 can be satisfied and the setting cannot be altered. Fig. 2 is an arrangement using only seven NAND gates while Fig. 1b uses eight NOR gates. DV bi-stable circuits may be connected in cascade in various ways to form counters and shift registers in manners which are compared with the JK equivalus and are illustrated in the following Figures (not shown): 4a a modulo 10 synchronous counter using JK circuits which may be replaced by the T function networks of Fig. 3b; 4b a modulo 16 synchronous counter using four DV circuits; 5b a synchronous counter or shift register using five DV circuits; 6b a shift register arranged such that information can be shifted forwards or backwards; 7 a modulo 1000 counter using three rings of five circuits coupled in cascade through gates which respond to the count of 9; 8 a circuit similar to 8 but in which the coupling gates operate in parallel; 9b an 8-4-2-1 code counter; 10b a 2-4-2-1 code counter; 11b a 3-excess code counter which can be modified to use the Aitken code; 12 a simplified modulo 10 counter.

Title: Improvements in marine hose with floats
IPC: F16L11/133
Filed: 1970-02-13
Abstract: 1277364 Buoyant pipes UNIROYAL Inc 13 Feb 1970 [6 March 1969] 7053/70 Heading F2P A marine hose, e.g. for conveying oil between a ship and shore installations has one or more floats 11, lla to keep the hose buoyant. The float is fitted free of axial movement about the hose and is of split construction, the split portions being secured by clamping means, e.g. stainless steel clamps 15. The assembled float comprises a circular inner groove to accommodate a shoulder 12 affixed to the exterior of the hose, e.g. by bonding. The radial depths of the shoulder and the coacting groove in the float may be so chosen as to provide a non-rotatable fitting of the float over the hose or one which allows rotation of the float on the hose. The shoulder 12 may be of rectangular or other cross-section and may be of natural or synthetic rubber, or other elastomeric compound and may contain reinforcements of textile material or glass fibres or metallic wire. The shoulder may alternatively be composed of multiple layers of thin sheets or strips. The float may be in more than two segments and there may be small gaps between opposed faces of the segments. Each float segment may initially be noncircularly curved so that the segments are fitted by deformation. Preferably, the float is made of a synthetic resin or a rubbery polymer in foam form, e.g. microcellular chemically blown closed cell polyurethane foam, or foams of P.V.C., polyolefins, natural or synthetic rubber latex or an admixture of foam and microspheres of glass. Each float-segment is provided with a marineproof and oil resisting shell, e.g. of polyethylene, neoprene, polypropylene, polyurethane, P.V.C., or epoxy resin. The shells may be reinforced with glass fibres or textile filaments and may be formed by rotational moulding. A shell thickness of 3/16 to 1/2 inch is recommended for most applications. In an alternative form of construction a hollow polymer shell constitutes the float (Fig. 5, not shown). Fig. 6 illustrates a float with bell-mouthed entry and exit ends 13g for the hose so as to facilitate the hose bending. In a hose construction wherein the end regions of the hose being more reinforced than the middle region for strength are less flexible, floats 11 having different inner surface configurations may be used at the said regions.

Abstract: 660,695. Positive and friction clutches; stopping in predetermined positions. PHILIPS ELECTRICAL, Ltd. March 16, 1949 [March 19, 1948], No. 7231/49. Class 80 (ii) [Also in Group XL (c)] A shaft control device for bringing a member, for example the rotor 32 of a radio tuning condenser, into any one of a number of predetermined positions comprises a system of arresting discs, spring-loaded pawls and a pawl-selector shaft 30, and has a setting of the selector shaft in which the member is completely freed for manual control thereof. The arresting discs 2-6 are adjustably held on the shaft 1 of the rotor 32 by friction discs 8 fixed to the shaft, each arresting disc having a peripheral recess 7 engageable by one of the pawls 17-21. The pawl 22 is actuated when manual control is desired and co-operates with a coupling element 10 connectting the shaft 1 to a gear wheel 9 driven, through a slipping clutch 13, by a motor 14. The other ends of the pawls 17-22 co-operate with discs 23-28 secured to the pawl selector shaft 30, each disc having a peripheral recess 29 and the arrangement being such that the recesses are relatively displaced symmetrically about the shaft 30. Upon turning of the shaft 30 to the required setting, one of the pawls, all of which are pivoted on a shaft 16, is actuated by its spring 31 to enter its recess 29 and the motor 14 then drives the shaft 1 until the actuated pawl enters its recess 7 to stop the shaft, thereby causing the clutch 13 to slip. The coupling element 10 (Fig: 2) is formed with projections 52, 53 and is pivoted at 51 to the gear 9. A spring 56 engages a pin 54 in the element normally to hold the projection 53 in driving engagement with a projection 57 on a bush 11 secured to the shaft 1. Upon actuation of the pawl 22, the projection 52 engages the pawl and the element 10 is rotated about the pin 51, to disengage the parts 53, 57 and stop the wheel 9 upon the engagement of the pin 54 with the edge of an aperture 55 in the wheel. The shaft 1 may then be manually operated. In an alternative form of coupling between the wheel 9 and shaft 1, a flexible band secured at one end to the wheel surrounds a cylindrical bush on the shaft and carries at its other end a projection engageable by the pawl 22. The two ends are connected by a spring so that normally the bush is gripped by the band, but upon actuation of the pawl 22 the band is opened to release the shaft 1 and the projection engages a pin on the wheel 9 to stop its rotation. Specification 634,781 is referred to.
