Abstract: 1,253,260. Animal feeding devices. G. P. ROSE-MILLER. 11 March, 1970 [21 March, 1969], No. 14888/69. Heading A1M. A calf-feeding arrangement comprises a row of tubular members 1 interconnected at sleeves 2, each member 1 having a projection 4 onto which a nozzle and teat assembly 3 is screwed. The row of members 1 is connected at one end to a tank 9 containing feed-stuff, e.g. milk by a rotatable joint 7 combined with a tap 8 and its other end has an angle portion 5 closed off by a cap 6. When filling the row of members 1 with milk, the arrangement is turned so that. the nozzle assemblies 3 point upwardly, cap 6 is removed and milk is allowed to pass from tank 9 into the row of members 1 while air is expelled through the opening at the end 6. The cap 6 is then replaced and the assembly returned to the position shown, thus allowing the calves to feed from the nozzles 3. Instead of the rotary joint 7 the tubular assembly 1 may be connected by a rubber grommet sealing provided in the wall of tank 9 or alternatively by a flexible rubber tube member.

Abstract: 1,259,098. Waveguides. MARCONI CO. Ltd. 11 April, 1969 [13 May, 1968], No. 22506/68. Heading H1W. A waveguide is made of a ceramic material provided with an internal layer of conductive material. The Specification describes a method of manufacture using a stainless steel mandrel having removable flanges at both ends. This is flashed with a thin layer (e.g. 0À0002 inch) of copper which is then built up by electroforming with a comparatively thick (e.g. 0À007 inch) layer of nickel. With the mandrel still in position, a thick (e.g. 0À1 inch) layer of alumina or zirconia is added by plasma spraying. The mandrel is then withdrawn. The resultant waveguide is capable of withstanding high temperatures and temperature gradients.

Abstract: 1307371 Optical comparison device I WILLIAMS F A WILLIAMSON and I H HITCHINSON 21 May 1970 [31 May 1969] 27705/69 Heading G2J A binocular viewing device for comparing supposedly identical articles X, Y placed sideby-side, whereby they are seen as a single superimposed image, incorporates a circular rotary shutter 30 which alternately obscures the view through each viewing aperture 22, 23 of the device. Images of the articles X, Y reach the eyes R, L of a viewer by way of planar reflectors 26, 24 and 27, 25. The shutter 30 is mounted on the shaft 32 of a variable speed electric motor 33 and incorporates three uniformly spaced apertures 31 of such size and arrangement that appropriate positioning of the shutter 30 affords a simultaneous view through the viewing apertures for accurate location of the articles on base 10. When the articles are correctly positioned they are viewed through 22 and 23 as a composite image, rotation of the shutter causing any differences between X and Y to give rise to a "blinking" effect at the frequency of rotation of the shutter; the speed of the shutter can be prearranged so that the "blink" is outstandingly noticeable to the particular user of the device. The shutter arrangement may be replaced by an intermittent light source or sources. In an alternative embodiment Fig.4, (not shown), the device is made in spectacle form with a nose piece (40 and sidearms (41). In this case there is provided a pivotal shutter (43) which is rocked by a spring powered motor (45) and which has side pieces (43a, 43b) which can be interposed between the reflector pairs 26, 24 and 27, 25.

Abstract: 1317903 Covering cores by winding DUNLOP HOLDINGS Ltd 13 Aug 1970 [14 Aug 1969] 40581/69 Heading B8G [Also in Division F2] Apparatus for winding filamentary or strip material around a pipe elbow former 17, having a part-toroidal section 17a and at least one straight cylindrical end 23, 24, includes a table 3 rotatable about an axis 19 and carrying supplies of the winding material, and means for moving the former during the winding operation so that the centreline 18 of the section of former being wound at any time is always aligned with the axis 19. From the position shown, the former 17 is raised vertically by a ram 21 until its straight end 23 is wound, it is then rotated through 90 degrees anticlockwise (together with an arm 2 and the ram assembly 33) about shaft 28 until its curved section is wound, and lastly it is again raised vertically by a ram 22 (which is itself now vertical) while its other straight end 24 is wound. These three steps are then reversed to complete a cycle and several cycles may be performed to complete the winding. The switching between the three different movements imparted to the former is controlled by microswitches actuated by stops carried by moving parts of the apparatus. The rams are hydraulically actuated, the pivoting of arm 2 and hence the ram assembly and the former 17 about shaft 28 is effected by an hydraulic motor 31, and the table 3 is rotatably driven by an hydraulic motor 46. The position at which the ram assembly is mounted on the end 20 of arm 2 may be adjusted by bolts 38 and a number of alternative bolt holes 41. The position of shaft 28 in relation to axis 19 may be similarly adjusted. Pipe elbows of differing curvatures may thereby be produced. The former 17, which may be of the collapsible metal or break-out plaster type, may be covered by a rubber sleeve, which is to form a lining for the pipe elbow and which is covered with helically wound, resinimpregnated glass fibre rovings. The rovings are led to the former in two sets, each of six threads which have been passed from reels 5 through a resin tank, Figs. 4-6 (not shown). One or both of the sets of six threads may be replaced by a single tape.
