Abstract: 1283700 Resistors MORGANITE RESISTORS Ltd 21 Nov 1969 [25 Nov 1968] 55866/68 Heading HIS Electrical resistors comprise a fired, claybonded refractory-carbon composition including at least one of the elements Ti, V, Cr, Mn, Fe, Co and Ni so as to decrease the rate of change of resistivity of the resistors about a given furnace temperature, such that a more uniform resistance value results for the batch of resistors in different parts of the furnace. The one or more of the elements are added in compound form, e.g. oxide, such that the total elemental weight is from 0-25 to 5-0% of the dry weight of the composition. Fig. 2 shows that the resistors containing one or more of the above elements approach their minimum resistance more gradually than that of Fig. 1, and also especially graphs 4-8, rise much less steeply from it.

Abstract: 1,205,467. Laundry sorting apparatus. CHICAGO DRYER CO. 2 Dec., 1968 [25 March. 1968], No. 57063/68. Heading B2H. [Also in Division B8] In a laundry apparatus comprising an ironer 10 and a folder 12, sheets are fed into the ironer on conveyor ribbons 13 by two operators. Should the sheet being fed into the ironer have a defect (e.g. tear or stain) one operator presses a push button (not shown) which actuates a marker 24 or 26. The marker 24, 26 presses a piece of gummed coloured paper on to the sheet and at the same time a warning light (not shown) is lit to indicate to the other operator that the defect has already been noted. The defective sheet passes through the ironer 10 and on to the feed ribbons 20 of the folder 12. Before entering the folder an electric eye 38 detects the coloured paper marker on the defective sheet and in response moves a by-pass plate 42 between the conveyor ribbons of the folder. The defective sheet is deflected by the plate 42 onto a discharge table 46 without passing through the folder.

Title: Optical Communication Systems.
IPC: G02F2/00
Filed: 1967-12-15
Abstract: 1,161,860. Optical communication system. INTERNATIONAL BUSINESS MACHINES CORP. Dec.15, 1967 [Jan.13, 1967], No.57203/67. Heading G1A. An optical communication system comprises a light source e.g. a multi-coloured laser or a group of arc lamps capable of producing an output including a plurality of wavelengths, means for modulating beams of each such wavelength and for combining them into a single transmission beam, and a receiver wherein the beam is separated into individual wavelengths and applied to detectors to develop respective output signals. The beam from a multi-colour laser 14, Fig. 1, is collimated and applied to a quartz crystal Q 1  wherein eight selected wavelengths have their polarization rotated respectively by 0 90 180 270 0 90 180 270 and the two sets of four beams of parallel polarization are separated by a birefringent prism P 1 . The colours in the two beams are rotated by respective quartz crystals Q 2 , Q 3  of half the length of Q 1  each to occupy four positions mutually at right angles but differing in the two sets by 45 degrees. The beams are split by birefringent prisms P 2 , P 3  and a further stage of crystals and prisms produces eight separate and parallel beams of different wavelengths. The beams may be used in a one way system in which they are combined into a single beam for transmission after being modulated, the combining arrangement being a similar crystal and prism arrangement. A similar but reversed tree is used for re-developing the individual information carrying beams. In a two-way system a broadband arc source 42, Fig. 9, collimated by a lens 44 is applied to an optical tree OT3 through a beam splitter BS3, and separate colour outputs fall on a mirror 56 through paths each including a filter 46, a beam-splitter 48, a birefringent plate 50, quarter-wave plates 52, and electrooptic polarizing crystals 54 to which the information signal is applied as amplitude modulation on a carrier frequency. The reflected beams can pass back through the prisms only if polarized by respective information signals in the crystals 54, and they are recombined by the optical tree for transmission through beam splitter BS3. The incoming information signals are separated in tree OT3 and reflected by respective beam splitters 48 on to photo-detectors 58, the outputs from which are filtered and registered. The system may be diplex using the same frequency at each end, or, transmission in the two directions can be simultaneous, with different modulating frequencies being used at the two terminals. An alternative arrangement for simultaneous two-way transmission in which transmitted, and received signals are separated by orthogonal polarization is described with reference to Fig. 12 (not shown).

After forming the convolution the pressure inside the tube is reduced and the die members moved so that a part 33 abuts stops 34. The two half-die members 6 are separated at the plane 11 and the die members moved back so that half-die members abut a body part 1 before they are brought together to enclose the convolution just formed in the first annular groove 13. Die member 5 is then withdrawn to the position shown in Fig. 1 ready for the production of the next convolution.
