Abstract: 881,100. Drying apparatus. KEIR & CAWDER (ENGINEERING) Ltd. Feb. 11, 1958 [Nov. 13, 1956], No. 34727/56. Class 34(2) Grass, corn, seed &c., is dried whilst falling through a chamber against an upwardly flowing gaseous stream. As shown grass, fed through a door 12, Fig. 1, or grain, fed through a door 12A, is lifted by scoops 32 of a slowly rotating member 4 such that it eventually falls between the various cross-members of the member 4 against a stream of hot air and combustion gas passing through the drying chamber I from a meshed inlet 8 to an outlet passage 42. A fan 13 coupled to the member drive, induces the gas stream to flow from a combustion chamber 15 and air inlet 17 through a passage 18, chamber 20, the chamber 1, a mesh 11 and a damper controlled outlet 37. From the fan the moisture laden gas may be discharged through a flue 14 or returned, at least in part, to the chamber 1 through a duct 14A. Solid or liquid fuel may be burnt in the chamber 15 and dried material is discharged from the chamber 1 through a door 9. The control of the apparatus may be automatically dependent upon the temperature of the gas leaving the chamber at 42. In a modified apparatus the chamber 1 is extended at 1A, Fig. 7, to house an arrangement comprising a baffle 7, Fig. 9, with a pivoted flap 7A such that in the baffle position shown grass is dried in a passage A. With the provision of additional baffles 7C, 7B, Fig. 10, and an adjusted baffle 7A, grain or shelled rice is dried, after being raised by the member 4, in a passage B which is between the baffle 7 and the extension wall. Washed asbestos fibre or fruit canning waste may be dried in an arrangement which comprises a screen 7F, Fig. 11, baffles 7, 7C, 7D and transverse wires 7E the falling slush passing through the inter-wire spaces at 7E on to the baffle 7D. The apparatus of Fig. 9 may be modified to act as a separator drier when drying lucerne, a horizontal grid 43,. Fig. 12, being lowered into position to engage the member 4 to strip the leaves from the stems such that the former may be carried by the gas stream to a cyclone separator whilst the latter are given additional drying time and eventually removed through the discharge door in the chamber.

Abstract: 1438823 Dispensing apparatus ELECTROTECNICA MELIA SA 30 July 1973 [29 July 1972 2 Feb 1973] 36233/73 Heading A4T  Apparatus for dispensing articles, e.g. drink and/ or foodstuffs, comprises an article containing zone, mechanical means for preventing removal of articles, and electrical means for detecting removal of an article and registering same. In one emodiment the apparatus Figs. 2 and 3 comprises a cooling system, a zone 1 for ice-cube manufacture, a chilled zone containing three rows of receptacles for bottles, a thermally insulating wall 7 and an unchilled zone containing one row of receptacles for bottles. Each receptacle is mechanically closed by a tiltable bar 13 and tilting of these bars is prevented by slidable elements 9 and bars 17. To remove a selected bottle from a receptacle the elements 9 are slid horizontally until there is no such element at the selected receptacle. A switch 10 is also rotated to a position corresponding to the row containing the selected receptacle and causes raising of the bar 17 by electromagnets 118. The selected bottle can then be removed by tilting the associated bar 13. An electrical detector is associated with each bar 13 and when operated sends a signal to a computer, the computer attaches a "weight" to the signal proportional to the value of the bottle removed and the weighted signal passes to a register where the total value of all bottles removed from the apparatus is stored. If the apparatus is one of several in use, e.g. in a hotel, a register for each apparatus may also be provided at a central site and the signals from all the apparatus may be fed to a further register for stock control. In a second embodiment the bars 13 are replaced by swingable plates, Fig. 12. In the event of a power failure the electromagnets 118, Fig. 3, allow all the bars 17 to drop to prevent removal of any article, and the electrical circuit includes a memory for storing any information in process of transmission to the register(s). The cabinet containing the receptacles may be closed by a door lockable and openable by a servant key. If a master key is used to unlock the door this key also causes cut-out of the electrical circuitry so that empty receptacles can be refilled without affecting the register. The detectors may be photo-electric devices, capacitive transducers, inductive detectors, switches or reed switches and magnets. The cooling system, when provided, may use absorption, compression, or the Peltier effect.

Abstract: 816,659. Electric digital-data-storage apparatus. INTERNATIONAL BUSINESS MACHINES CORPORATION. Dec. 23, 1955 [Dec. 30, 1954], No. 36928/55. Class 106 (1). In a device for storing data by the spin-echo technique (stimulated or mirror echoes) a plurality of words are entered in succession into a sample (water) and each word, as it is entered, is labelled by a variation of the inhomogeneity of the polarizing field, in such a way that any one of the words can be selectively read-out from the sample. As described a plurality of sets of coils 1, 2, 3, Fig. 2, are positioned around the sample, thus permitting a large number of different variations to be made to the inhomogeneity of the polarizing field by energizing them either singly or in combination or for different durations. Two examples of the storing and selective recovery of two words are shown in Fig. 4, using stimulated echoes. Each word is preceded by a pre-pulse and also by a labelling pulse of inhomogeneity varying current I. In the first example, Figs. 4B, 4C, the current I passes through a first set of coils, say coils 1, Fig. 2, for the first word and through a second set, say coils 2, for the second word. Once entered, the words can be selectively read out by applying first a recollection pulse and then a current I through a selected one of the two sets of coils. Thus to read out the second word a current is passed through the coils 2. In the second example, Figs. 4D, 4E, the several different variations in the polarizing field areproduced by currents of different durations in only one set of coils.
