Abstract: 1,144,779. Shoots; endless conveyers. GUNSON'S SORTEX Ltd. 13 June, 1967 [16 June, 1966], No. 26996/66. Headings B8A and B8S. [Also in Division B2] In a sorting machine objects to be sorted are delivered to a sorting zone 15 by means of a shoot 13, Figs. 1-3, and/or an endless belt 30, Fig. 4, having a surface made of P.T.F.E. The shoot and/or belt is provided with a number of longitudinally extending ribs 24 or 31 so that the surface contact between the shoot and/or belt and the objects is reduced. The objects, e.g. diced potatoes or carrots to be sorted in accordance with their colour, or frozen peas, are delivered from a hopper 10 on to a feed table 11 vibrated by an electromagnetic vibrator 12 and pass down the shoot 13 in substantially single file to enter the zone 15 where they are viewed against a background 17 by photo-sensitive equipment 16. Signals are passed from the latter to a comparator 20 so that when an undesired object is viewed a signal is passed to an ejector 21 which removes the undesired object by a blast of air. The shoot 13, Figs. 2 and 3, which has a funnelshaped portion 22 communicating with a U- shaped channel portion 23 may be made of aluminium and is lined internally with a layer 25 of P.T.F.E. The ribs 24 may be triangular in cross-section. In addition to, or in lieu of, the table 11 there may be provided an endless triangular-ribbed belt 30, Fig. 4, which may be formed of an anti-static elastomeric material and which is provided on its outer surface with a layer of P.T.F.E. Alternatively, the belt is formed entirely of P.T.F.E.

Title: Improvements in a film shifting device for photographic cameras
IPC: G03B19/04
Filed: 1928-09-21
Abstract: 297,439. I. G. Farbenindustrie Akt.- Ges., (Assignees of Slocum, B. A.). Sept. 21, 1927, [Convention date]. Magazine hand cameras for roll-films.-A filmfeeding device of the kind in which the filmfeeding members are prevented from returning to their initial position ready for the next feeding operation until the first feeding movement has been completed is characterized by a pawl, mounted on the movable, part of the feeding-de-- vice, and having ratchet movement over stationary teeth during the feed stroke, and teeth engaging the pawl and preventing the return of said movable part unless this part has completed its feeding movement. As shown in side view in Fig. 1 and in front view in Fig. 2, the removable back 3 of the camera 1 carries a guideway 12 for a reciprocatable slide 15 to which is pivoted at 18 a feed member 19 pressed forwardby a leaf spring 21 and having claws 20 so shaped that they engage and feed the perforated film 6 during the downward stroke only of the slide 15. This stroke is effected by operating a knob 22 working in a vertical slot 23 in the camera back 3, and the return of the slide to its initial position is effected by springs 17. Pivoted at 25 to the slide 15 is a pawl comprising a resilient arm 26 carrying at its free end a, claw 27 which, in the initial position of the slide 15, is caused by a spring 28, pressing on the arm 26, to rest in a cut-away portion 28 of the flange 14 of the guideway 12. During the feed stroke of the slide 15, this pawl ratchets over bevelled teeth 24 cut in the edge of the guide flange 14. If the operator fails to complete the feed stroke, return of the slide 15 by the springs 17 is prevented by engagement of the claw 27 with one or other of the teeth 24. At its lower end 30 below the teeth 24, the guide flange 14 is cut down to a thin knife edge over which the claw 27 slips under the action of the spring 28 when the feed stroke has been completed, so that on release of the knob 22 the claw 27 may ride on the upper surface of the guide flange 14 and permit the return of the slide 15 by the springs 17. A downwardly-struck tongue 31 on the arm 26 co-operates with the flange 14 to prevent excessive rotation of the pawl by the spring 28. The film 6 is pressed against the focal aperture 8 by a leaf spring 9 anchored to posts 10 on the camera back 3.

Title: Key actuated machines
IPC: G06C7/06
Filed: 1945-10-20
Abstract: 618,861. Calculating-apparatus. ARMSTRONG, J. J. V. (Script Manufacturing Co.). Oct. 20, 1945, No. 27618. [A Specification was laid open to inspection under Sect. 91 of the Acts, Oct. 20, 1945.] [Class 106 (i)] To make a more compact calculating machine, the keys are spaced at half the usual distance, centre to centre. In a first embodiment, Fig. 2, the numerals are carried by the tops of guide posts 16, the keys 19 for numerals 2-8 comprising two open-sided connected shells engaging adjacent guide posts. The key 21 for the numeral 1 is half the size of a key 19, while the key 23 for the numeral 9 is larger than the other keys so as to embrace completely its related post. To enter any numeral except 9, the operator's finger engages and depresses two keys as illustrated by the dot-dash circles. The depressed keys compress springs 60, Fig. 4, inside the guide posts 16, and depress a rod 28 carrying a block 40, which first depresses and then rocks a two-armed crank 42, 44 mounted on a spring pivot 43. The arm 44 is pivoted to a rack bar 26 and the initial depression of the crank 42, 44 lowers the rack bar 26 to engage its upper teeth with a totalizer pinion 64. The rotation of the crank then moves the rack bar 26 to the right in Fig. 1 until a member 27 engages the stop 20 of the lowest key depressed, to enter half the integer, the other half being entered on the return movement of the rack bar, when the lower teeth engage the pinion 64. The rack bar 26 is maintained horizontal despite the circular movement of the arm 44 by having a circular groove 57 engaging a rod 56. In a modification, Fig. 6, half of each numeral is carried on each of the related keys. The keys may be made of transparent plastic. Totalizer. Each numeral wheel 96 is mounted loosely on a shaft 63 and the pinion 64, having eighteen teeth is mounted on a sleeve 65, an eccentric part 72 of which carries a coupling disc 68 having ten projections loosely engaging in openings 70 in the numeral wheel and ten projections facing towards the pinion 64, but only one or two actually engaging the pinion due to the eccentricity, as seen in Fig. 1. Transfer. A plate member 73 rotatable on the shaft 63 is connected by a spiral spring 75 to its related numeral wheel and is in driving connection with the sleeve 65 and therefore the coupling disc 68 of the next higher denomination. The plate 73 is held against rotation by a stop 77, but when the numeral wheel reaches zero position, a cam 78 displaces the plate from the stop and the spring 75 rotates the plate 73 and therefore the coupling disc 68 of higher denomination through half a revolution, and because of the extra teeth on the coupling disc, one is added into the higher denomination. Zeroizing. Depression of a clear key 93, Figs. 2, displaces the rack bars 26 sideways against spring pressure to free them from the pinions 64. The numeral wheels 96 then return under the pressure of the springs 75 until the projections 78 abut against the frames 73.
