Abstract: <PICT:0748733/IV(a)/1> <PICT:0748733/IV(a)/2> A method of producing a granular product from a voluminous powder which contains a hardenable condensation product of the carbamide type, e.g. of urea, thio-urea, melamine, and dicyanamide with an aldehyde such as formaldehyde and a hardening agent and which is compressed between two rollers so as to produce a coherent layer which is subsequently granulated, is characterized in that the two rollers are unheated and rotate in opposite directions at equal peripheral speeds, the width of the layer formed being limited by projections on the surface of one of the rollers, which projections are spaced apart by a distance equal to the width of the other roller.  It is preferred that the surfaces of the two rollers are spaced apart by not more than 4 mm. and that the width of the roller surfaces does not exceed 15 cms.  In an example, a fibrous material impregnated with urea-formaldehyde condensate is mixed in a ball-mill with ammonium chloride, zinc stearate and a dyestuff is treated.  Referring to the drawings, rollers 1 fit closely between radial projections 5 on rollers 2 to which is fed, through the slit between rollers 2 and edge 8, powder from supply vessel 6 fitted with a reciprocating feedplate 7.

The modified chromium dioxide particles occupy 40-50% of the total volume of the magnetizable layer and are aligned in a magnetic field during the casting of the layer on to a polyester foil support. The modified chromium dioxide may be prepared in a two-stage process as follows: first, crystallization nuclei are produced by heating an aqueous mixture of CrO 3  and TeO 1  under oxygen pressure, the product being cooled powdered, washed with distilled water, filtered and dried in a vacuum; second, an aqueous mixture of CrO 3  and the prepared crystallization nuclei is heated under oxygen pressure and the product is then processed as in the first stage. The polyurethane resin is the reaction or condensation product of a polyester containing free hydroxyl radicals and an isocyanate. Such polyesters may be obtained by the reaction of polycarboxylic organic acids, e.g. adipic and phthalic acids, with polyhydric alcohols, of which at least a portion are trihydric alcohols. The isocyanate may be hexamethylene diisocyanate, tolylene diisocyanate (toluene - 2, 4 - diisocyanate), triphenyl methane triisocyanate, or the reaction product of a diisocyanate with a trihydric alcohol (such as glycerol, hexanetriol, trimethylol propane) or mixtures of trihydric alcohols.

In a centralized dictation system, seizure of a central station simultaneously by two or more substations is prevented by arranging that the substations are connected to the central station in a certain order of priority. The substations are each provided with a relay, two contacts of which are normally closed and form part of a series chain to the control station. When a start switch, e.g. the cradle switch, at one of the stations is operated a circuit is completed via the series chain and contacts of the switch for energizing the relay. The latter then completes a holding circuit, breaks the chain, energizes a pilot lamp and connects the various control switches by the substation to the central station. In the event of attempted simultaneous calls, the station nearest to the central station along the chain takes priority. The closest station to the central one is preferably a transcribing station. The recording medium is a magnetic band and provision is made for sending a warning signal when the band is nearly exhausted. The station transducers are provided with "record/play-back " keys and also with " instruction " keys for causing the operation of punches which perforate a paper tape. The latter is scanned at the same speed as the band and the instructions relate to such items as end of letter, &c. A further key is provided for signalling a control station operator by operating a buzzer thereat and each substation is also provided with a buzzer which is energized if the station attempts to seize a busy control station.

[Class 7 (vi)] A valve-actuating rocker with hydraulic means for taking up clearance comprising a piston operating against oil pressure in a cylinder in one arm of the rocker, means being provided coacting with the piston whereby a part of the rocker-operating force is transmitted directly through the rocker arm and part through the oil chamber. In the form shown, one arm 12 of the rocker is bored to receive a plunger 38 which is formed with a wedge surface 45 engaging a corresponding incline on a plunger 44, bearing on the top of the push rod 14, oil being admitted behind the plunger 38 past a ball valve 30. The oil is taken from the usual lubricating- passage 24 in the rocker pivot, from which it escapes through a hole 23 and annular groove 22. The ball is retained by a disc 33, between which and a corresponding disc 36 bearing against the plunger 38, is arranged a spring 35. The disc 33 is formed with grooves in its edge for the passage of oil to the chamber behind the plunger 38, which chamber is kept of small dimensions. Preferably, the discs 33 and 36 are formed with projections 34, 37 which meet when the compensating- mechanism is collapsed to its limit, the spring 35 being also so designed as to fill the annular space around the projections 34, 37 when fully compressed, so that all the oil is expelled, together with any air or gas present. An air escape passage may, however, be provided as shown at 29. In a modification, the plunger 44 does not project from the rocker arm, but is retained within a recess in the arm by a small flange formed after the plunger is in position. The proportion of the force transmitted directly through the rocker arm is varied by alteration of the angle of the wedge.

The characters are arranged on the type wheel in the order of the binary value of the corresponding telegraphic code. Thus "E" is represented by 10000 (value 1), A by 11000 (value 3) and S by 10100 (value 5). Since a line-spacing signal is given by 01000 (value 2) a notch has to be provided between E and A in order that the counter shall step from 1 to 3. The usual provision of a space in the second position of the type wheel is avoided by interposing the notch and preventing the generation of a printing pulse by an inhibiting circuit including a multivibrator having a period T3, Fig. 4, triggered by the character notches 5, 6, 7, 9, 10 &c. The control signals are therefore recognized in the same way as character signals by comparison with the counter output, but since the corresponding comparator signal (e.g. 8) occurs during one of the inhibiting pulses B the print hammer is not operated.
