Road - traffic signals on vehicles; semaphore and pointer luminous signals; semaphore and pointer signals.-A road-traffiic signal for indicating the direction of intended movement and the stopping of vehicles comprises an indicating-member movable into and cut of either of two signalling positions, a second indicating - member and means for moving the second indicating member into indicating position upon movement of the first member beyond one of its indicating positions. All operations are controlled from a single manually-actuated element by means of rack-bars and pinions; and means are provided for mounting upon the vehicle so that the member carrying the indicating- means is adjustable in a plane at right-angles to the plane of movements of the indicating-means A casing 23, 24, Fig. 1, contains a semaphore 26 pivoted on a pin 25, a target member 46 pivoted at 49 on the same pin 25 and a double rack-bar 32 having one rack 30 engaging a pinion on the semaphore coaxial with the pivot-pin 25 and a second rack 43 engaging a pinion 41 carried on a shaft 39 pivoted to the casing. The rackbar 32 reciprocates to turn the semaphore to right or left, but on further movement .of the semaphore from its position indicating ' right ' to the inverted position, a pin 51 on the rack-bar engages the bottom of the slot 50 on the target, Fig. 8, causing it to rotate into the horizontal position. A hollow bracket-arm 22 carrying the indicating-members ends in a sleeve 52 through which passes a rod 54 adjustably fixed to an angle-plate 56 by a pivot 55 and by its reduced end 59 which carries a nut 60 and slides in a slot 58 carried by the angle-plate. This angleplate is secured, Fig. 13, by means of bolts 66 and fingers 62 engaging slots 63 to a member 67 having a clamping-jaw 64 embracing a post 20 of the wind-screen. A link 86 with slot 92 sliding on a finger 91 on the angle-plate has at one end a second rack-bar 87 engaging the pinion 41 and at the other end is bent round to triangular form and has an upwardly-directed finger 87<1> engaging a slot 88 in the hand-lever 85.

Abstract: 1,199,264. Apparatus for heat shrinking plastics tubing. HI SHEAR CORP. 11 March, 1969, No. 12792/69. Heading B5A. [Also in Divisions H2, H3 and H5] Apparatus for heat-shrinking tubing on to elongated objects, e.g. electrical conductors, comprises a housing and two sets of heating elements pivotable from an open position in which the tube and elongated object can be inserted between them to a closed position in which they surround the tube. As shown, the heater assembly 10 comprises a housing 12 mounted on base 14. A plurality of hook-shaped radiant heaters 24-39 are mounted on base members 40 and 42, each base and attached heating elements defining one of the sets of heating elements. The bases 40, 42 are hinged together about a fixed bar at 62 and are supported on cams 74, 76, the cams being mounted on shaft 78 to which wheel 80 is attached. Rotation of wheel 80 through 180 degrees rotates cams 74, 76 and allows the heating elements to open from positions 32, 24 (Fig. 2), to positions 82, 84 (Fig. 2). The heating elements are preferably constructed from quartz with an embedded heating coil and are connected in parallel with adjacent pairs, e.g. 24, 25, in series. The elongated object and tube are inserted with the heaters in the open position and are moved between the closed, energized coils at the desired rate to shrink the tubing. The power supply to the heaters is preferably through a delay device which gives a high current for a short period, e.g. 1¢ sec., and then reduces the current to the rated value, thus ensuring a fast warm-up. In an alternative embodiment the heating device may have only one movable jaw and a switch which energizes the heater as the heating elements reach the closed position.

Title: Improvements in or relating to glass articles and methods of producing same
IPC: H01B1/00
Filed: 1954-05-04
Abstract: A silver-oxide-containing glass is provided with a silver coating by exposing said glass to electromagnetic radiation in the presence of water vapour to cause the formation of the silver coating on the exposed surface of the glass.  The radiation may be in the form of light or heat, althrough ultra violet radiation produces the coating more rapidly; it is stated that formation of the coating also takes place in darkness although requiring a long time.  The glass may be provided with an electroconductive coating having a desired configuration, i.e. a coating with highly conductive and highly resistant regions, by masking the regions desired to be highly resistant or by subjecting the glass to a pattern of radiation having the configuration desired for the conductive coating, e.g. by projecting a source of light through a photographic negative having the said configuration. The process may be used to form mirrors, printed circuits or devices to be used in warning signals, time-delay switches and detonators for fuses and explosives; these devices comprise a silver-oxide-containing glass base provided with a pair of spaced electrodes which lead to an electrical circuit, the arrangement being placed in a water-vapour environment which causes the formation of a silver coating, after a desired time, thus completing the electrical circuit.  Specification 780,304 [Group XXIII] is referred to.

Title: Improvements in and relating to the preparation of catalytic masses for hydrocarbon synthesis
IPC: B01J23/48
Filed: 1944-07-07
Abstract: A catalyst for the Fischer-Tropsch process produced by the reduction of a metal carbonate precipitated by means of an alkali carbonate is reduced at least partly in the presence of residual alkali, and the alkali is completely removed after or during the reduction.  A volatile alkali may be used, which is removed during the reduction. Non-volatile alkali, if used, is removed by washing and preferably boiling with water until the washings have a pH value of seven.  Used catalysts which contain residual alkali may be restored by a similar washing treatment.  The reduction is preferably carried out in the presence of a previously reduced similar catalyst.  In addition to nickel or cobalt, the catalyst may contain thorium dioxide and a small proportion of cerium oxide.
