Abstract: 873,770. Reducing iron ores. OFFICE NATIONAL INDUSTRIEL DE L'AZOTE. March 28, 1958 [March 30, 1957], No. 10105/58. Class 72 [Also in Group XII] A process for the production of iron by the reduction of a sub-divided natural iron oxide with a reducing gas comprises maintaining the oxide in a turbulent fluidized bed by a stream of reducing gas, the temperature being above 565‹C. and the rate of gas flow being such that the frequency of collisions between the particles s is  sufficiently great to seal the pores in the particles. Natural iron oxide comprises naturally occurring oxides of iron and the products of decomposition of other naturally occurring iron compounds. As shown the finely divided oxide is fed through a device 6 into a vessel 1 having a partition 7 extending across the vessel but not to the bottom thereof. A reducing gas is fed into a space below a perforated plate 3 to produce a fluidized bed 4 in the vessel. The oxide passes below the plate 7 and iron particles are discharged at 9 with a gas speed of 0.4 to 2.0 metres per second the discharged iron particles are non-pyrophoric due to sealing of the pores. Specification 754,182 is referred to

Abstract: 791,895. Substation circuits; sets. KUNCKEL, H. April 3, 1956 [April 5, 1955], No. 10216/56. Class 40 (4). A local battery subset comprises a transistor amplifier for amplifying the output of a batteryless (i.e. moving-coil or piezo-electric) microphone and means for causing the transistor to oscillate to generate an audio-frequency calling signal. As shown, Fig. 2, the instrument 22 is a combined micro-telephone. The contacts 17 ... 20 are controlled by a three-position control member 26, Fig. 4. In its first or outer position it connects the micro-telephone direct to the coil winding 5 for reception of the calling signal. In its intermediate depressed condition the contacts are arranged as shown to utilize the micro-telephone as a receiver which is connected to the output side of the transistor amplifier 9 the input of which is connected to line via the transformer 4. In the fully depressed or speaking position of the control member 26 the contacts 17 ... 20 are changed over so that the instrument 22 acts as a transmitter and the direction of amplification of the transistor is reversed. The switch 12 when operated connects in the feed-back coil 7 which causes the circuit to oscillate to produce a calling signal. In a further embodiment, Fig. 1 (not shown), a separate receiver is provided which is connected in a conventional anti-side-tone circuit. The amplifier 28 and its switch control members 12, 26 may be mounted in a handset, Fig. 4, the micro-telephone being located in the mouthpiece 30 and connected by a sound duct 27 to an earpiece 29 of narrow width for facilitating its insertion inside a steel helmet.

Title: Improvements in automatic payment and change giving apparatus
IPC: G07F17/42
Filed: 1934-04-04
Abstract: 436,225. Money-delivering apparatus. GRANZELIUS, K. A. T., 16, Skepssbron, Stockholm. April 4, 1934, No. 10261. Convention date, April 5, 1933. [Class 116] In a machine adapted to deliver change coins representing the difference between a tendered coin or coin inserted through separate slots 2-6 for different denominations and a fixed sum to be collected, e.g. in respect of a ticket supplied from an associated delivery mechanism, the inserted coins serve to bring the path of movement of rotating actuators 26, 26<a> into coincidence with toothed setting wheels 34 of a totalizing counter controlling the coin ejecting mechanism. An inserted coin is conducted to a cut-away portion 17 in one of a series of discs 16 corresponding to the slots and carried by a shaft 10 revolved by hand, or by an electric motor whose circuit is temporarily closed by the coin as it is inserted. At the bottom of each cut-away portion 17 is a lever 20 pivoted at 21 to the disc and coupled by a bell-crank 24 to one of a series of sliding rods 25 connected with appropriate actuators 26, 26<a>. These actuators are carried by three wheels 27 secured to the shaft 10 and corresponding to the units, tens, and hundreds order setting wheels 34 of the counter, and each is provided with one or more teeth for engaging and stepping up a wheel 34 by one or more units in the respective orders. The change coins are contained in a series of receptacles 152, each having an opening 176 at its lower end normally covered by a sliding sleeve 161 operable by a lever 165, and each provided with an ejector 159 sliding in an opening 160 in the sleeve 161, so that one or more coins are discharged from the receptacle upon operation of the ejector 159 and lever 165 by respective cams 155, 156 on an operating shaft 146 as determined by the setting of one of a series of profiled discs 171. These discs are carried by two shafts suitably geared by wheels 187, 192 with the counter. Some of the rods 25, depending on the fixed sum to be collected, are extended as at 73 so as to be operable by a sliding plate 71 loose on the shaft 10 upon operation of an external pushbutton. In operation, an inserted coin is carried round by a disc 16 and, by engagement with a fixed wall 29, depresses the corresponding lever 20 so that the appropriate actuators 26, 26<a> are deflected to engage the wheels 34 upon the continued rotation of the shaft 10, whereby the counter registers the value of the coin tendered, after which the coin is discharged and the actuators returned to inoperative position. The push-button operating the plate 71 is then depressed which, during a subsequent revolution of the shaft 10, steps up the counter by an amount equal to the maximum reading of the counter less the sum to be collected, so that the counter and the profiled discs 171 controlling the change mechanism are then set to the value of the change due. The operation of the push-button also clutches the shaft 146 to the driving motor so that the change due is then ejected.
