Abstract: 1,230,759. Ammonium salts. FISONS FERTILIZERS Ltd. 24 June, 1968 [1 April, 1967], No. 15023/67. Heading C1A. Ammonium salts are prepared by injecting into a reaction zone an atomized stream or streams of an acid or acids and a stream of ammonia gas flowing in the same sense as the acid stream or streams, the reaction zone showing an increase in cross-section along the axes of the zone from the points of injection of the acid and ammonia. The finely atomized ammonium salts formed are separated from steam and reacted ammonia in a vapour liquid separator such as a baffled chamber or a cyclone, and may be rendered particulate by prilling or rotary granulation. The unreacted ammonia, after separation of the water produced in the reaction zone if necessary, is recovered by scrubbing with acid, the acid then forming part of the acid feed to the reactor. The acids used may be phosphoric, nitric, sulphuric or mixtures thereof. The walls of the reactor may be heated by a steam jacket and mechanical means for scraping the walls may be provided. Means may also be provided for washing deposits off the wall, e.g. with phosphoric acid. In one example, phosphoric acid feed to the reactor is preheated to 80‹ C.

Abstract: 1,232,105. Vehicle spring suspensions. BAYERISCHE MOTOREN WERKE A.G. 10 July, 1968 [12 July, 1967], No. 33004/68. Heading B7D. The two wheels 9 of an opposed pair are each suspended from a vehicle chassis 5 by a link assembly 1 comprising a trailing longitudinal arm 2 which is laterally and torsionally flexible, is fixed at its leading end to a generally transverse shaft 4 journalled in the chassis, and carries at its trailing end a wheel support 1<SP>1</SP> to which is fixed one end of an oblique rigid arm 3 the other end of which is pivoted about an oblique axis to the free end of a crank arm 6, the crank arm 6 being fixed to, and rotatable with, the shaft 4 of the link assembly 1 of the other wheel of the pair whereby vertical movement of one wheel relative to the other causes relative vertical movement between the transverse and oblique pivot axes of the link assembly of said other wheel resulting in lateral tilt thereof. Such a suspension is stated to provide automatic camber and toe-in adjustment on unequal spring deflection of the wheels, such as when rounding curves, but to retain parallelism of the wheels when their spring deflection is uniform, such as in straight travel. As shown in Fig. 1 the crank arms are curved to permit their mutually crossed disposition, and the link arm 2 is coplanar with the wheel support 1<SP>1</SP>. Fig. 3 shows an arrangement where the wheel support 1<SP>11</SP> is disposed above the horizontal plane of the link arm 2. The characteristics of the suspension may be determined by selection of the angular disposition of the shafts 4 relatively to the true transverse direction in both horizontal and vertical planes, and of the dimensions of the link arms 2 and 3 and crank arms 6.

Abstract: 1,251,055. Acoustic wave amplifier. MINNESOTA MINING & MFG. CO. 14 Nov., 1968, No. 54141/68. Heading H3U. [Also in Division H1] An acoustic wave amplifier includes a ZnO body 10 having a high resistivity of about 10<SP>4</SP> # cm. and a high Hall nobility of about 480 cm<SP>2</SP>/V. sec., both values being measured at - 100‹ C. and both of which parameters decrease with increasing temperature. In the embodiment the ZnO amplifying body 10 is grown from vapour in a nitrogen or argon atmosphere, and may contain Li ions to decrease the free carrier concentration. A SiO 2  buffer rod 12 is attached to the input end of the body 10, and ZnO input and output transducers 14, 16 are respectively connected to the rod 12 and the body 10. A u.h.f. signal generator 28 is controlled by a pulse generator 32 to provide a series of u.h.f. pulses to the input transducer 14 for conversion to a pulsed acoustic wave. The pulses from 32 also pass through a delay 34 and serve to synchronize high voltage pulses from a power supply 26 with the acoustic wave pulses in the body 10. The acoustic wave may propagate through the body 10 in a compression or shear node. The temperature of the body 10 is adjusted to a level which gives the requisite values of resistivity and Hall nobility, e.g. using dry nitrogen gas. The connections to the body 10 and to the transducers 14, 16 are made by sputtering In then Au. The connections to the buffer rod 12 are made by sputtering " Nichrome " (Registered Trade Mark) then Au. Cu wires are bonded to the connections by means of epoxy resin containing Ag. The body 10 may also be used as an acoustic wave delay time, in which case the amplification obtained may compensate for internal losses within the device.

Abstract: 1,267,148. Vibratory compactor. CLARK EQUIPMENT CO. 4 Dec., 1970 [15 July, 1970], No. 57672/70. Heading A1B. A vibratory compactor has a ground engaging roller 10 in which a shaft 24 is centrally mounted and rotated by hydraulic motor 22. An eccentric weight 36 is fixed to the shaft and has a bolt 44 attached to it. A further eccentric weight 38, having a projection 42, is free to rotate. According to the direction of rotation of the shaft: the bolt 44 will either engage the edge of the movable weight and hold the weights in alignment, see Fig. 4; or engage the projection 42 and hold them in opposition, see Fig. 5. In order that the same centrifugal force is produced in each case, the former arrangement must have a lower rotational speed than the latter; the ratio of speeds depending on the choice of weights. Two speeds of rotation may therefore be used, while retaining the same centrifugal force, by reversing the direction of rotation of the shaft. The roller may be towed by a tractor 14 or be selfpropelled.

Abstract: 1290654 Windscreen wiper motor REGIE NATIONALE DES USINES RENAULT and AUTOMOBILES PEUGEOT 6 Jan 1970 [7 Jan 1969] 687/70 Heading A4F [Also in Division H2] In a system for intermittently operating a motor M which drives a windscreen wiper, closure of switch i energizes transistor 1, relay R, and capacitor 7 until the capacitor is charged sufficiently for the relay to respond. Contact 3 then disengages from contact 2 and engages contact 4 to energize the motor. As it rotates, the motor causes contact 12 to change from contact 13 to contact 14 whereby the capacitor 7 is discharged through resistors 5, 6, and the emitter-base junction of the transistor 1. Relay R is released, and the motor circuit is established through contacts 12-14, 2-3, and 9-10. When the motor completes one revolution, contact 12 changes-over to contact 13 so that the motor is braked and the transistor circuit is prepared for another cycle of operations. For continuous operation of the motor, the contact 9 is engaged with the contact 11. In a modification, the motor is of the three-  brush type, and a selector switch provides high and low speed operation as well as intermittent operation, Fig. 4 (not shown). A stabilizer comprising a Zener diode in shunt with a further capacitor may be connected across the elements R, 1 and 5. A diode permits discharge of the further capacitor only through the transistor circuit, thus providing a time-lag in the release of the relay R, Fig. 5 (not shown).

Abstract: 1295172 Radio signalling ROBERT BOSCH ELEKTRONIK GmbH 6 Feb 1970 [7 Feb 1969] 5685/70 Heading H4L In a calling arrangement, particularly for a radio telephone system, in which the calling signal comprises two audio-frequencies transmitted either simultaneously or successively, the receiver includes a resonant circuit which may be successively tuned to each of the audiofrequencies by switches controlled by a monostable device operated by the rectified output of the resonant circuit in such manner that the resonant circuit is tuned to the first audiofrequency when the monostable is in its stable state and is tuned to the second audio-frequency for the duration of the unstable state during the reception of the first audio-frequency. The rectified output of the resonant circuit and the output of the monostable in its unstable state are supplied to an AND gate unmuting the receiver and operating a calling device. As shown in Fig. 1, a calling signal, consisting of frequencies f1, f2 in sequence, received at 2 is supplied via an amplitude limiter 3 to a resonant circuit 6, 7. Initially monostable 14 is in its stable state causing transistor switch 10 to be conductive to tune the circuit 6, 7 to frequency f1. The output of circuit 6, 7 is rectified at 12, and after a delay at 13 triggers the monostable 14 to its unstable state, whereby the circuit 6, 7 is tuned to frequency f2 by the switching of transistor 11. This produces a very short pulse at the output of AND gate 18 which has no effect on a bi-stable 22 including a delay device 58. When the frequency f2 is received a longer pulse appears at the output of gate 18 which triggers the bi-stable 22 to switch on a warning light 26 and to operate a switch 4 to connect the loud-speaker 5. The bi-stable 22 is returned by operation of a button 27 after the conversation has terminated. In a modification, Fig. 3 (not shown), the calling signal consists of n repetitions of the sequence f1, f2, and the bistable 22 is replaced by an n-position counter, which when it reaches its full count, unmutes the receiver and triggers a monostable device to operate a multivibrator producing a calling tone. If the counter does not reach its full count in the required period a timing circuit returns the counter to its zero position.
