Abstract: 1510510 Bucket wheel excavators KOCH TRANSPORTTECHNIK GmbH 26 Sept 1975 [1 Oct 1974 22 May 1975] 39535/75 Heading E1F [Also in Division B8] A bucket excavator comprises buckets pivotally mounted on a wheel and movable about their pivots between positions in which they are respectively positioned for digging in opposite directions of rotation of the wheel. In one embodiment, Fig. I, each bucket has two pick-up openings 5, 5' and the pivoting of the bucket is limited by the engagement of an arm 23 with a stop 21 or 21'. Springs 22, 22' are provided to bias the bucket into a central position. In another embodiment, Figs. 6 and 7, each bucket 42 is in the form of a sector of a cylinder and is pivoted on a shaft 27, when the direction of rotation of the wheel is reversed, by means of an arm 30 and a fork member 31. The fork member is pivotally mounted on a shaft 43 secured to a support 44 of a ring 34, the shaft 43 also pivotally mounting two arms 45, 45' engageable with dampers 46, 46'. The rotation of the ring 34 is reversed simultaneously with the reversal of wheel 33, but at a slightly greater speed, so that the fork member 31 overtakes the corresponding bucket and drives the arm 30 towards the direction of rotation. A friction device (not shown) allows the ring 34 to be driven at the same speed with respect to the wheel 33 when the ring has taken its maximum of advance after a direction reversal.

Abstract: 1,198,397. Automatic exchange systems. SEIMENS A.G. 19 Aug., 1968 [22 Aug., 1967] No. 39556/68. Heading H4K. An impulse repeater or producer comprises an electronic pulse generator and a plurality of electromechanical relays which control the length of and the interval between the pulses emitted by the generator by varying the time constants of various circuits within the generator. The time constants are varied by switching in different resistors into the circuits. In addition to the obvious correction of break/make ratios of the impulses, the relays determine the duration of interdigital pauses, the transmission of seize and disconnect pulses in interexchange signalling and the recognition of start and release pulses at the beginning and end of a call. One such repeater may be connected permanently to a trunk or may be allotted thereto merely during impulse transmission.

Abstract: 855,475. Indicating liquid-levels. SHAND & JURS CO. Dec. 17, 195 [Dec. 26,.1957], No. 40759/58. Class 123(1) A liquid-level gauge comprises a float 17 which is guided by adjustable wires 96, 97 in a tank 13 and is connected by a metal gauging tape 16, passing through sheave mountings 84, 92, a vibration inducing unit 19 and guide tubes 18, to a tape drum 24 which is rotatably mounted on a shaft 26 in a housing 22 fixed by a bracket 12 to the tank 13. The vibration inducing unit 19, which is adapted to agitate the tape 16 rapidly to overcome friction existing between it and the drum 24 and the sheave mountings 84, 92 so that accurate liquid level recordings can be obtained, comprises a plate 104 which is accommodated in a casing 78 and carries pins 102, 103 arranged on opposite sides of the tape 16. The plate 104, urged by a spring 109 in an anti-clockwise direction away from the tape 16, is rotatably mounted on a stud 106 screwed into a base plate 107 bolted to the casing 78. Permanent magnets 113, 114 mounted on opposite ends of the member 104 are influenced by a permanent horse-shoe magnet 119 mounted on the shaft of an electric motor 116 which is carried by posts 117, 118 secured to the base 107 and is supplied with power through leads 126. Before taking a level reading the motor 116 is switched on so that, due to the magnetic coupling, the pins 102, 103 oscillate and repeatedly vibrate the tape 16. The motor may be rotated mechanically, or by hand, and the number of poles on the magnet may be increased. The magnets 113, 114 may alternatively be replaced by soft iron. In another arrangement the vibration is produced by two jets of air spaced apart to engage opposite sides of the tape. A fixed fulcrum may be placed near one side of the tape so that forces can be recurrently applied on the other side at points spaced from the fulcrum. Alternatively two fixed fulcrum points can be used the force then being applied between them on the other side of the tape. In a further modification rapid vibrations are applied to the guide pipes. The vibration unit may be controlled remotely.

In a printing process comprising an ink transfer step, a particulate ink is applied to a substrate and fused to form the desired image. The ink comprises two components, at least one of which is particulate comprising an epoxy resin and the other a curing agent for the resin, at least one of the components containing one or more colourants. The components are maintained " separate ", i.e. at least one of them is in the form of discrete particles which do not contain the other, until the print fixing step. One or both of the components may contain a finely divided filler. The ink transfer step may be carried out in two stages by separately applythe two components if they are both in particulate form. Alternatively the substrate may be precoated with the curing agent and the particulate epoxy resin containing the colourant applied in the ink transfer step. The precoating may be achieved using a soln. of the curing agent or by spreading particles which are fused before applying the epoxy resin. Alternatively the epoxy resin may be applied over the entire substrate by similar means and the ink transfer step uses only particles of curing agent containing colourant. Preferably both epoxy resin and curing agent have m.p. in the range 70- 180‹ C. Suitable curing agents are dicyandiamide, tetrahydrophthalic anhydride, p-toluidine fluoborate or triethylenetetramine. The curing agent may be dispersed in a resinous carrier, e.g. a polyamide. The particles may also contain an anti-agglomerating agent, e.g. SiO 2 .

Abstract: 1352910 Straightening R GALDABINI 2 Sept 1971 [6 Nov 1970] 40917/71 Addition to 1185927 Heading B3E [Also in Divisions G1 and G3] The method of straightening an elongated workpiece as described in Specification 1,185,927 is modified in that succeeding bending strokes of the ram are increased by preselected amounts rather than as a function of the residual error between the actual and desired final shape of the workpiece. After imparting a first bending stroke S 1  to the bar as in Specification 1,185,927, bending strokes S 2 , S 3 , each exceeding the preceding stroke by an increment a, are applied to the bar until the error E between the actual and desired final shape falls below a first preselected value E A . Subsequently, bending strokes S 4 -S 6  are applied to the bar until the measured error E is below a second preselected value E B , the strokes S 4 -S 6  increasing progressively by an increment b which is less than the increment a. The increments a and b in the two bending stages need not be constant and more than two stages may be provided. The apparatus for carrying out the method is similar to that described in the parent Specification.
Patent GB-979721-A (GB)
Title: Ferrite particles and method for their preparation
IPC: C04B35/26
Filed: 1961-11-16
Abstract: A method of producing single-domain-size, acicular ferrite particles comprises dispersing acicular iron oxide particles in an aqueous metal salt solution, this solution comprising the chloride, sulphate, or nitrate salts of the metal or metals required as the bivalent component of the ferrite, adding a solution of the ammonium salt of a low-weight carboxylic acid so as to precipitate the metal salt of the organic acid on to the iron oxide particles, filtering off the particles and heating them which (a) decomposes the organic salt and (b) forms the ferrite by diffusion of the metal ion through the iron oxide.  The iron particles are produced by forming seed particles in a sol by adding ammonium hydroxide to ferric chloride, dialysing the sol, and precipitating iron oxide hydrate on to the seeds by dispersing the sol in a ferrous salt solution through which oxygen is bubbled, metallic iron being added.  Alternatively the particles may be produced by the method disclosed in Specification 665,554.  The iron oxide particles formed are acicular having a length between 300<\>rA and 10000<\>rA and a width between 150 DEG <\>rA and 5000<\>rA, and a length-to-width ratio of between 2:1 and 40:1. These are also the size ranges of the final ferrite particles.  A dispersing agent, e.g. sodium hexametaphosphate, or an alkyl aryl polyoxethylene compound is added to the iron oxide/metal salt dispersion.  The metals involved may comprise one or more of Cu, Sr, Sa, Cr, Mn, Fe, Co, Ni or one or more of these metals with Ca, Mg or Zn.  The ammonium salt of the carboxylic acid may be ammonium formate, acetate, proprionate, succinate, oxalate and volerate and precipitation may take place between 50 DEG  C. and 80 DEG  C.  The heat treatment takes place at temperatures below 600 DEG  C. e.g. 400 DEG  C.  The final ferrite particles may be formed into magnets using a resin binder, e.g. acrylic resin or phenol aldehyde, or may be used in recording tapes.  Reference has been directed by the Comptroller to Specification 943,480.
