Title: Fruit juice extraction
IPC: A47J19/02
Filed: 1963-09-30
Abstract: 1,016,644. Extracting juice from fruit. FRANCISCO ANGEL QUIROZ. Sept. 30, 1963, No. 38407/63. Heading A4C. Juice is extracted from rind fruit, such as citrus fruit, by enclosing the whole fruit 202a so that substantially its entire exterior surface is supported, piercing the rind, and deforming a substantial portion of the rind from its convex configuration to compress the fruit and express juice through the opening left by the piercing step without further rupture of the rind. Whole fruit is fed singly from a hopper 139 via a channel 141, a feeder plate 91 and an aligning plate 81 to a position between opposing elements 36, 120 relatively movable toward and away from one another to enclose and support the whole fruit the rind of which is then pierced by spaced, tubular prongs 48 and the fruit compressed by a plunger 121 acting on the resilient element 120 which in turn deforms the rind to express juice through slots in the prongs 48 and via a discharge funnel 37 to a collecting tank 146. A dished, ejector disc 45 is located within the rigid, concave element 36 and is movable therein on a shaft 43 extending therethrough, the arrangement being such that the prongs 48 pass through apertures in the disc 45 as the latter is retracted when a fruit is to be compressed and that after the juicing a shaft return movement of the disc 45 causes fruit residue to be propelled from the prongs 48. The whole operation is con trolled in timed relationship by levers and links driven from a cam gear 3. An electrical circuit is provided to prevent operation of the machine in the absence of fruit in the channel 141, when the cover 104 is open, or when the juice tank 146 is full.

Title: Improvements in or relating to paper-feeding mechanism
Inventor: LAMBERT DONALD RUDOLF
Filed: 1956-12-19
Abstract: 830,668. Typewriters &c. INTERNATIONAL COMPUTERS & TABULATORS Ltd. Nov. 1, 1957 [Dec. 19, 1956], No. 38705/56. Class 100(4) A paper feeding mechanism for a machine in which imprinting is effected, as by stylii, on a constant speed continuously fed paper, has an auxiliary feed driving means provided to increase the feed speed to produce multiple line spacing. Continuously stationery 1 is fed at a constant speed over a platen 8 and under stylii 3 by pin wheels 4 rotated by gears 9, 10 from a drive shaft 11. The shaft 11 is driven at a constant speed from the main machine drive by a shaft 21 through a differential gearing 12, 17, while an auxiliary drive from a shaft 23 through a differential gearing 13. 18, increases the speed of the shaft 11 to produce multiple line spacing. The shaft 23 is driven by a ratchet wheel 24 acted on by a pawl 25 attached to an arm 26 secured to a gear wheel 27 loose on the shaft 23 and engaged by a rack 29. A cam 32 on a shaft 33 rotating at the speed of the shaft 21 acts through a follower 34 and links 35, 37, 38, on the rack 29. A crank 41 is pivoted at 40 to the link 38, which is in turn pivoted at 39 to the rack 29, and is engaged either by a neutral pin 44 coaxial with the pivot 39 in the datum position of the rack 29 or by one of a series of secondary pins 45, Fig. 6 (not shown), which can be inserted in corresponding holes 43 in the crank 41. When the pin 44 is engaged in the crank 41 the cam 32 does not produce any movement of the rack 29 but when one of the pins 45 is engaged a movement is caused which on the return of the rack 29 causes the stationary feed speed to increase to effect multiple line spacing. Insertion of one of the pins 45 is effected by electromagnets controlled by an electric circuit including two manually settable switches made operative by a cyclically operated timing switch through either a machine or a manually controlled additional switch. Electromagnets also control an interrupter 46 which prevents movement of the auxiliary feed linkage and of an interposer which renders mechanism for selecting the pins 45 operative.

Title: Device for selectively detecting the occurence of fission products in gases
Inventor: GOUPIL JEAN
IPC: G01T1/178
Filed: 1958-12-01
Abstract: 898,219. Reactors. COMMISSARIAT A L'ENERGIE ATOMIOUE. Dec. 1, 1958 [Dec. 5, 1957], No. 38708/58. Class 39(4). In a nuclear reactor cooling-gas monitor, the short lived fission products in the gas, eg. CO 2 , are detected to indicate the fracture of fuel element sheathing. A signal corresponding to both short and long-lived fission products and a second signal representative of only the long-lived products are developed separately and applied to a comparison circuit, the output of which indicates the presence of the short-lived fission products. To reduce the effect on the fission product reading, of the short-lived radio-active isotopes produced within cooling gas itself by neutron bombardment, readings are also obtained corresponding only to the short-lived isotopes (i.e. nitrogen 16), which are then subtracted from the first reading. As shown, cooling gas is admitted to detection chamber 2 and is observed by scintillating elements 7, 7a through the windows 6, 6a. The pulse outputs from 7, 7a are applied, through pulse selectors 42, 42a in the right and left-hand channels to the comparison circuits 13, 16 and 13a, 16a. The right-hand and left-hand channels deal, respectively, with the radiations from fission products and ccoling gas isotopes. Window 6 is thinner than 6a and is transparent to fission product and the gas radiations. Selector 42 accepts only fission signals, i.e. those corresponding to energies less than 4 MeV and rejects insotope signals, i.e. corresponding to #-emission from 17, 16 and greater than 4 MeV. Window 6a is transparent only to isotope radiation signals and selector 42a accepts only these, i.e. corresponding to # energies greater than 4 MeV. Initially, gas flows continuously through the chamber 2 and as switches 14, 14a are closed the voltages 12, 15 and 12a, 15a correspond to the fission products and isotope products respectively (both short and long lived). Subsequently, valves 3, 4 are closed and switches 14, 14a are opened and only the long-lived oroducts of fission and from the gasremain in the chamber 2, to produce corresponding signals at 12 and 12a. Consequently, the potentials e and e a  represent the activity of the short-lived fission products and short-lived radio-active isotopes respectively. To allow for lack of selectivity in the right-hand channel, the voltage e a  is subtracted from e, the difference being indicated at 21.

Title: Improvements in work-feeds for shearing and nibbling machines
IPC: B23D27/00
Filed: 1958-12-04
Abstract: 864,333. Strip-feeds. TRUMPF, C. Dec. 4, 1958 [Feb. 1, 1958], No. 39077/58. Class 83 (4). In a nibbling-machine having a reciprocatable tool 12, the work 17 is fed automatically only during return movements of the tool. The work is supported on a roll 32 and fed by contact with the curved or toothed periphery of an element 31 pivoted at 39 on a horizontal feed-slide 29; alternatively, the element 31 may consist of an eccentrically-mounted disc or a pawl. The slide 29, in ways 22 in a housing 18, is connected by a link 27 to a vertical slide 23 in the housing, which is keyed at 20 to an arm 16 adjustable angularly about a guide-sleeve 11 for the tool ram 10 to vary the direction of feed. An arm 33 carrying roll 32 is also adjustable about the axis of the shear blades 12, 35. A pin 24 in slide 23 is pressed into a groove 14 in an adjustable collar 13 on the ram 10 by a spring 36, and is withdrawn from the groove by a projection 37 on link 27, if the ram is raised beyond a certain level. The radius of the upper part 15 of collar 13 is greater than that of the lower part, so that on its down-stroke, part 15 engages the pin 24. During its return strokes, element 31 slides over the work. The element may be raised by a lever 311 and retained in the raised position as by a ball-catch 29<SP>1</SP> engaging the element or its pivot-pin 39 if this is fixed to the element. Adjustment of the length of the feed-stroke can be effected by adjusting collar 13 on the ram 10, or by using an adjustable link 27. Instead of the pin 24, a two-armed lever may be pivoted on the housing 18 and connected between slide 29 and the collar 13 or ram 10. Alternatively, a gear meshing with teeth on the ram or collar and on the vertical slide may be used for the feed. In Fig. 3, a toothed band or teeth 40 are fixed to member 31 by plates 44 secured by a dowel and screws 45.
