Abstract: 1463419 Alkali metal and alkaline-earth metal cyanates STAMICARBON BV 26 June 1974 [28 June 1973] 28391/74 Heading C1A An alkali metal cyanate or an alkaline earth metal cyanate is prepared by cracking urea into a gaseous mixture of ammonia and iso-cyanic acid and reacting the mixture with an aqueous solution or suspension of a hydroxide, carbamate or carbonate of an alkali or alkaline earth metal. In one embodiment a cracking-furnace A is supplied with liquid urea at 133 C. through line 1. At the same time nitrogen gas is supplied through line 2 and is introduced into A together with the liquid urea. The urea is cracked in A at 350 C. into iso-cyanic acid and ammonia, which are led in the gaseous state through line 3 to the absorption zone B together with the nitrogen. B is further supplied with air through line 5 and with sodium hydroxide solution saturated with sodium cyanate at 40 C. through line 6. In B, the gas streams and the liquid stream are contacted in concurrent flow, and sodium cyanate formed. An air stream which is enriched with nitrogen and loaded with water vapour and ammonia leaves reactor B through line 7. Ammonia can be recovered from this stream in a known way. An aqueous slurry of sodium cyanate flows to centrifuge C through line 8 and the solid is separated from the liquid. The liquid flows through line 9 to solution vessel D. D is supplied with solid sodium hydroxide through line 14. The solid sodium cyanate separated off in C is passed to washing-section E through line 10 to be washed with wash water supplied through line 11. The pure sodium cyanate is dried in trough F with air supplied through line 15 and is subsequently discharged through 16. Calcium cyanate is made analogously by supplying B with 10À8% milk of lime.

Title: Improvements in and relating to driving mechanism
IPC: B66D5/00
Filed: 1920-10-12
Abstract: 173,887. Igranic Electric Co., Ltd., (Cutler-Hammer Manufacturing Co.). Oct. 12, 1920. Operating clutches. - A driving motor having independently movable elements is combined with a clutch which connects one of the elements to a driven device and with means controlled by the movement of the other element for engaging and disengaging the clutch. In the form shown, an electric motor is used, having a rotor 24 and movable stator 14 which actuate, through a clutch 27, 28, a driven device in the form of an arm 12 which controls the brakes 2, 3 normally applied to an elevator or like brake drum 1 by a spring 10 and pivoted arms 4, 5. The stator swings on the rotor shaft 17 and has a projection 31 engaging, under the action of an axial spring 32 and biassing weights 26, a cam plate 30 mounted rigidly on the upstanding frame member 7 in which the shaft 17 is journaled. Loose on this shaft is a clutch member 28 integral with a sprocket wheel 16 from which a chain-drive is taken to the lower countershaft 20. Rigidly mounted on the shaft are the rotor and the other clutch member 27. The shaft 20 has a short crank-arm 19 coupled by links 21, 22 to the brake-operating lever 12, the length of the crank being such that in addition to causing a decrease in the mechanical advantage of the motor when the shaft rotates in either direction from the position shown, it causes the end of the link 21 to abut on the shaft 20 and bring the motor to rest. Starting with the brakes on under the action of the spring 10, energization of the motor rocks the stator to an extent determined bv the counterweights 26, the cam 30 thereby being caused to move the rotor and stator bodily to the right against the action of the action of the spring 32. This engages the clutch discs 27, 28 and the ensuing rotation of the rotor drives the shaft 20 through the clutch and chain gear and causes the lever 12 to separate the brake arms 4, 5. Rotation continues until the abutment of the link 21 on the shaft 20 stops the motor and the torque between the motor elements is balanced by the restoring couple due to the spring 10. The brakes are thus held off as long as the motor is energized. When it is de-energized the clutch is at once disengaged and the spring 10 reapplies the brakes without the possibility of over-setting due to rotational momentum of the rotor since this is entirely disconnected from the brake-setting mechanism.

Abstract: 1,056,008. Suspended vehicles. ANGLOTRANSVAAL CONSOLIDATED INVESTMENT CO. Ltd. July 8, 1965 [July 10, 1964]. No. 29036/65. Addition to 959,178. Heading B7L. An improvement in the locomotive described and claimed in the parent Specification, consists in that each suspension link 13, Fig. 2, is triangular in shape, the apex of the triangle being pivoted to a stub axle 16 of a running wheel 14 engaging the track 12, whereas the corners 29, 30 of the base of the triangle are connected respectively to the locomotive frame 11 and a driving wheel 18 at points offset on either side of a line passing through the pivot 16 and at right-angles to the track 12. By this construction the weight of the locomotive tends to force the driving wheels 18 into engagement with the undersurface of the track 12. The pivot 29 may be movable in a guide in the frame 11 or there may be a further small link between the pivot 29 and the frame. The wheels 18 are carried in a bogie frame (not shown), pivoted to the frame 11 about a horizontal transverse axis.

[Also in Group XXXVI] A variable resistor or inductor comprises a rotating helically grooved operating rod driving a contact member and an arresting member each provided with a protuberance or dimple engaging the helical groove and at limit positions the arresting member abuts a fixed stop. In Fig. 1 the contact member 4 movable along resistance track 2 has a dimple 5 engaging the helical groove 6 and the arresting member 7 is U-shaped and straddles the operating rod 3 and comprises in a side wall 9 a protuberance or corrugation, 11, Figs. 2 and 3, which also engages the groove 6 whereby rotating the rod 3 drives both the contact member 4 and the arresting member 7 as 5 and 11 ride along the groove 6 and when the arresting member 7 abuts a fixed stop such as the end wall 13 as shown the protuberance 11 cannot disengage the groove 6 and continued rotation of the rod 3 is therefore prevented. The resistor frame 1 may fit closely around the member 7 to prevent any appreciable deformation of the side walls 9 and 10. The invention is concerned only with the provision of the arresting member 7 and Fig. 1 is otherwise as described in Specification 722,284, [Group XXXVI].

Abstract: 932,239. Selective printing; printing processes. ELECTRIC & MUSICAL INDUSTRIES Ltd. Sept. 10, 1959 [Sept. 12, 1958], No. 29220/58. Classes 100 (2) and 100 (4). [Also in Group XL (b)] In selective printing apparatus a character is first recorded magnetically on a moving magnetic tape 2, Fig. 1, by a transducing head mechanism 1 which is moved so as to cause a predetermined path or pattern of paths 5, Fig. 2, to be traced on the tape, means 10-14 bearing coded representations of characters being provided for energizing the head at predetermined points in the path or pattern so as to apply to the medium a series of discrete magnetized areas 4 having the configuration of the character, thereafter magnetic powder is applied to the tape to cause it to adhere to the discrete magnetized areas, and finally the powder is transferred from the tape to a further medium to which the powder is caused to adhere to provide a print of the character in visible form. As illustrated in Fig. 1, the head mechanism is reciprocated across the tape by means of a rotating cam 7 which engages a lug 8 to displace the mechanism against a return spring 9, the path traced being of zigzag form. In alternative constructions, Figs. 3 and 5 (not shown), the head mechanism comprises a wheel rotating about an axis parallel to the tape and supporting on its periphery a plurality of heads which come into operation successively as they engage the tape. The pattern traced within this construction comprises a plurality of parallel paths across the tape. A plurality of characters may be recorded simultaneously by the provision of a plurality of heads on mechanism 1. The means for energizing a head to record a character comprises a plurality of coding discs 10 or drums, one for each character it is desired to record, the discs carrying on their peripheries patterns of black and white areas arranged so as to produce impulses at the appropriate instants by reflection of light from a common source 13 to photo-electric cells 14. The discs are rotated by a motor 11 which also rotates cam 7 to reciprocate the head mechanism. A control circuit (not described) is employed to select and connect the appropriate photo-electric cells to the head mechanism in accordance with characters to be recorded. Inking.-The recorded characters are rendered visible by passage of the tape through a developing tank 15 in which a suspension of a magnetic powder, e.g. black iron oxide in an alcohol or water is sprayed on to the tape. Multiple-web arrangements.-Finally copies of the recordings are transferred to waxed papers 22 by passage of the tape in contact with the papers between pairs 19, 20 of heated rollers. Demagnetization.-The tape is demagnetized by an erase head 25 and residual magnetic powder removed by brushes 26 before it passes again in the form of a continuous loop to the recording station.
