Title: Improvements in or relating to conveyor systems
IPC: B65G17/20
Filed: 1948-10-05
Abstract: 648,508. Endless chain conveyers. KING, Ltd., G. W., and BURROWS, A. T. C. Oct. 5, 1948, No. 25990. [Class 78 (i)] The invention relates to the type of conveyer comprising an endless driving chain fitted with rollers arranged in pairs disposed alternately in planes at right angles to each other and running on surfaces provided by a track of rectangular or box-like section adapted substantially to enclose the chain, and loadsupporting bars associated with the chain and adapted to project through a slot or passageway in one wall of the track. According to the invention the chain is made up of a plurality of links 10 each of which comprises a metal strip or blank bent to a U or substantially U-shape, the links being interconnected by means of pins 11 which serve also as spindles for the rollers 12. As shown in Fig. 2 the rollers run in a track 14 of square section. The closed end of each link 10 is slotted at 17 (see also Fig. 1), to receive a load bar 16 mounted on the corresponding pin 11 and projecting through a slot 15 in the lower wall of the track 14, the load bars 16 being mounted only on those of the pins 11 which are horizontal. The bars 16 are connected in pairs by vertical pivots and are provided with means for receiving loads W. According to the Provisional Specification the holes in the open ends of the. links 10 may be of keyhole formation, the limb of each keyhole being too narrow to receive the diameter of. a pin 11 but wide enough to receive portions of the pin provided with flats. This arrangement is such that the pins may be inserted or removed when two adjacent links are mutually perpendicular but not when the chain is straightened out.

Abstract: 766,922. Contact members for switches. GENERAL ELECTRIC CO. Sept. 8, 1954 [Sept. 14. 1953], No. 26034/54. Class 38(5) A contact member particularly suitable for use in transformer tap changing switches is immersed in an inert medium such as oil, nitrogen or rare gases, and comprises a conducting base covered with a layer of copper oxide 0.002 to 0.008 mils. in thickness which serves as the contacting surface. The arrangement avoids the galling or wearing of the surface due to the surfaces coming into sliding contact under pressure. Fig. 1 shows a tap-changing switch in which each fixed contact 18 is adapted to be in turn gripped between contacts 17 pressed strongly together by a spring 19 and mounted on a rotary arm 13. Specification 502,393 is referred to.

Abstract: 1,036,889. Cigarette-making machines. D. T. N. WILLIAMSON and MOLINS ORGANISATION Ltd. July 5, 1963 [July 6, 1962; Jan. 14, 1963], Nos. 26111/62 and 588/63. Heading A2C. The wrappers of cigarettes are tested by sealing of the exterior of the wrapper from the unwrapped ends of a cigarette and applying suction to the sealed off exterior part of the wrapper. The cigarettes C (Figs. 1 and 2) are conveyed in flutes 3 of a band 1, the flutes being provided with pads 4 which co-operate during testing with pads 9 in flutes 8 of a drum 6. The pads 4 and 9 seal off the exterior of the wrapper from the ends of the cigarette and a chamber 19 is thus formed between the pads, the drum 6 and the band 1 to which suction is applied through holes 10 and 11 in the drum 6. The holes 11 cooperate during testing, with slots 16 in a stationary carbon ring 14, the slot 16 being connected to a suction source via a pipe 19a. Should the wrapper be faulty air is sucked in through the open ends of the cigarette being tested to alter the capacity of capacitors comprising fixed plates 20 and movable plates 21. The change in capacity is utilized to operate rejecting mechanism. In a second embodiment (Figs. 3 and 4) the cigarettes C are held between flutes 31 in a band 30 and flutes 34 in a drum 33. A band 30 and a drum 33 are provided with co-operating parts 35 and 41, 37 and 43, 38 and 44, 39 and 45, 40 and 46, and 36 and 42 respectively, so that the cigarette is held against the end parts 36 and 42 and chambers 48 and 47 are formed at one end of and around the cigarette. Suction is applied to the chamber 47 by a pipe 63 via holes 50 and 51. The chamber 48 is connected by holes 53 and 54, slot 60 in a carbon rings 57 and pipes 64 and 66, to a detector device 67. Any pressure drop arising in the chamber 48 as a result of a faulty wrapper is thus detected by the device 67 and transformed into an electrical signal for operating a rejecting device. The rejecting device may comprise a secondary suction drum to which suction is selectively applied under the control of the detector device so that faulty cigarettes are taken by the secondary drum (Figs. 5, 6 and 7, not shown). Alternatively the detector device may cause selective operation of a blower device operating to blow faulty cigarettes from a line of delivered cigarettes on a conveyer (Fig. 8, not shown).
