B.; Shoemaker Road, Blue Bell, Pennsylvania, U.S.A.) May 17, 1935, No. 14489. Convention date, May 26, 1934. [Class 118 (ii)] [See also Group XI] A rotary beacon light comprises a light source on the focal axis of an annular optical system which is inclined to the vertical and rotated about a vertical axis, the equatorial section of said optical system having one part which projects a horizontal sheet of light, a second part which projects a second sheet of light which is upwardly inclined but in continuation of the horizontal sheet, and a third part which projects horizontally a pencil type beam of light which is separated from the said sheets of light. The light projected horizontally forms a dot and dash signal to an observer on the horizontal, whilst the light projected upwardly forms a flash signal to an observer above the horizontal and within its vertical range. In the form shown, a substantially spherical beacon with a practically smooth exterior surface has its optical axis 12 inclined at 15‹ to the vertical axis 11 about which it is rotated and which contains the light source at the focal point 23. It comprises an annular optical system which includes four modified Fresnel lenses 17, 18, 20, 21, each extending over 60‹, which project a continuous sheet of light one part of which is horizontal as at 22 and the other part is upwardly inclined at 30‹ to the horizontal as at 24, the sheet of light having a divergence of 6‹. The annular optical system also includes a bull's-eye lens 25 extending over the remaining 120‹ so as to project the pencil type beam of light 31, and an inner converging lens 26 may be employed to produce perceptible gaps 27, 28 between the beams. The remainder of the sphere is constituted by a lower metal reflecting cap 13 opposite which is arranged a similar reflecting or non-reflecting cap or a bull's-eye lens 15 for projecting an additional beam substantially vertically. Colour screens may be disposed between the light source and the lenses. The beacon may be associated with a photo-electric or like device adapted to switch off the artificial light source in daylight, the rotating lenses then co-operating with rays from the sun to form a daylight signalling beacon.

Abstract: 1340222 Automatic control systems for cathodic protection ENGELHARD MINERALS & CHEMICALS CORP 12 May 1971 [13 May 1970] 14566/71 Heading G3R An automatic control system for cathodic protection of metal 3 immersed in an electrolyte 4 comprises a DC supply 5 connected to the anode 1 and cathode 3, a comparator 8 which receives a reference potential from circuit 16, 17 and a signal from a reference electrode 2 associated with the cathode 3 and which produces an error signal controlling the supply 5 to maintain the electrode 2 at the reference potential, and a timer 20 which controls the supply 5 and an electronically operated sampling switch 9 so that the signal from the electrode 2 is applied to the comparator 8 during periods when the supply to members 1, 3 is interrupted, the arrangement thus ensuring that the signal is free from anode current induced errors. In a typical cycle of operation, Fig.2 (not shown) the supply 5 is turned off by the timer 20 after which follows a delay period timed to permit the decay of anode current-induced cathode coating dielectric charge. At the end of this period the switch 9 connects the electrode 2 to a memory device 10 (e.g. of the capacitor type) for another period long enough to enable the device 10 to attain the potential of the electrode 2, the output of the device 10 being passed to the comparator 8 which, together with member 10, is connected to a ground conductor 14. At the end of this period the switch 9 is opened and the supply 5 is restored for a predetermined period during which it is controlled by the error signal from the comparator 8.

Letters and the like, systems of transmitting and delivering. -Apparatus for sorting letters comprises superposed endless bands upon a driving pulley, the upper flights of the bands being spaced apart and extending horizontally within a housing opposite sorting stations where letters are placed upon the bands to pass to delivery shoots at the return bends of the bands. Fig. 1 shows the front end, and Fig. 2, the delivery end, of a double-sided apparatus. Fig. 3 is a central section, and Fig. 6 shows details of the delivery shoots to which the letters pass. Superposed bands 2 are wrapped on driving pulleys 1, and the upper flights of the bands diverge over anti-friction rollers, extending to the delivery end of the apparatus over vertically spaced shelves 3, Fig. 3. At the delivery end the bands pass vertically downward between rollers 5, 12, jockeyrollers 14 carried by nuts being movable by keyactuated spindles 21 to tighten or slacken the bands, Fig. 7. The return flights 2a pass horizontally over shelves 6, Fig. 3, The sorting stations comprise grids 7 at spaced points opposite the upper flights, the grids 7 presenting staggered rows of slots 8. Each slot 8 registers with a band so that letters passed through the slots are carried by the bands to delivery shoots 24 at the delivery end of the apparatus. The bars above the slots have inclined front faces imprinted with the destination of the letters. Each shoot 24 is formed with an endless conveyer 25 which draws the letters to fingers 28 or discs 27 carried by the lower conveyer rollers. As the letters fall on to the conveyers 25, projections 30, Fig. 6, on the delivery nozzle of the shoot, engage them as shown and turn them over so that all the letters are deposited flat on the conveyers 25. The letters are stacked at the bottom of the shoot, and the rotating fingers 28 lift the stack so that the last arriving letters pass to the bottom of the stack. Belts 37, moving in troughs 38 at each side of the apparatus, are geared to the main drive, and convey the letters to the sorters working at the grids 7, and letters &c. which are too bulky for insertion in the slots 8 are placed by the sorters on an overhead conveyer belt 40 working in a trough 41. These letters are returned by the belt 40 to the front end of the apparatus through a shoot 42. Glass panels 48 are arranged at the sides of the grids 7. In a simpler construction than that shown, a single set of superposed bands pass over a single driving pulley, the sorting stations being preferably arranged at both sides of the apparatus.

Abstract: 1275342 Masted lift trucks CLARK EQUIPMENT CO 26 March 1970 [23 April 1969] 14786/70 Heading B8H A mast assembly 34 for a lift truck comprises a stationary outer mast section 38 and intermediate 40 and inner 42 mast sections movable by a ram 54, guide rollers (98) (100) (104) (106), Fig. 4 (not shown), mounted within the mast sections and a load carriage 86 mounted on the mast section 42 such that the load carriage may be elevated to a full free-lift position prior to elevation of mast sections 40, 42 and in addition, the guide rollers may be serviced without requiring complete disassembly of the mast assembly 34. The mast sections 38, 40, 42 are formed in channel shape (44) (62) (74),Fig.4(notshown), and each is connected at its rear by the bars. The multiple cylinder ram 54 comprises five hollow cylindrical members, Fig. 14 (not shown), the outer of which (144) is connected to an anchor plate 160 to which chains 166 are anchored, said chains being reeved over sprockets 158 on a crosshead 154 mounted on the ram 154 and connected to the load carriage 86. To effect the initial free lift of the carriage 86 fluid pressure is applied to the ram 54 thereby raising the sprockets 158. Further chains 168 are connected to the plate 160 and extend about sprockets 170 on the lower tie bar 68 of mast section 40 and are anchored to brackets 172 secured to the channel members 44 of the outer mast 38. After free-lift of the carriage 86 has taken place, elevation of the intermediate mast section 40 out of mast section 38 is caused by the elevation of the anchor plate 160 and chains 168 on application of further fluid to ram 54 and the inner mast section 42 is simultaneously telescoped out of mast section 40, thus providing maximum extension of the mast assembly 34. By mounting a ramp (180) under the drive wheels 24, Fig. 5 (not shown), the guide rollers may be serviced by lowering either the inner mast section 42 or the intermediate mast section 40 to positions beneath the wheels 24. This is achieved by removing a stop member 70 on the intermediate mast section 40 which abuts the upper tie bar of the outer mast section 38, actuating the ram 54 to effect free lift of the carriage 86 and then raising the inner mast section 42, maintaining it raised by means of a lifting bracket 134 and then lowering the intermediate mast section 40 by means of ram 54 to expose the rollers (100), Fig. 9 (not shown), while in a similar manner the rollers (106) may be exposed by lowering the inner mast section 42 on removal of a member 82 from its lower tie bar, the intermediate mast section being held raised by a chain (188), Fig. 10 (not shown).
