Abstract: 1493859 Facsimile apparatus XEROX CORP 21 April 1975 [25 April 1974] 16463/75 Heading H4F [Also in Divisions D2 and G2] A facsimile image is reproduced on a solid state persistent electrochromic uniformly distributed upon a substrate having a surface material which has a resistivity greater than that of the electrochromic material by: (a) treating the surface material to increase its conductivity and thereby reduce its resistance to a level less than or about equal to that of the electrochromic material; (b) passing electrical current through the electrochromic material by creating a potential between a movable electrode and the far side of the surface material and moving the electrode in imagewise configuration to thereby form an image in the electrochromic material; and (c) converting the surface material back to its original state of resistance greater than that of the electrochromic material. The surface material may comprise polystyrene, polyethylene or polyethyleneterephthalate, its resistance being reduced by applying heat thereto, or it may comprise paper its resistance being reduced by wetting it with water. Alternatively the surface material may be photoconductive or an electrical switching device. The persistent electrochromic material may comprise an alkali metal halide, e.g. NaCl, RbCl, KCl, LiF, NaBr, KBr, KI or RbBr, or WO 3 , MoO 3 , CuO, CuMoO 4 , CuWO 4 .2H 2 O, CuS, Cu 3 O 4 , CuWO 4 , Co 2 S 3 , CoS, MoS 3 , MoWO 4 , MOS 2 , SnS, TiS 2 , TiO, VO, NiO, CeO 2 , Ce 2 S 3  or SnSe, and is preferably 500-10,000 Š thick so that it may be wrapped around a recording drum and helically scanned by a stylus, e.g. a tungsten stylus. Specific recording material described comprises WO 3  evaporated on to a paper substrate which is wetted and placed in contact with a sheet of conductive black construction paper.

Abstract: 772,595. Linear-dimension gauges. MASSEYHARRIS-FERGUSON (MANUFACTURING), Ltd. May 24, 1954 [June 16, 1953], No. 16537/53. Class 106 (2). [Also in Group XX] A gauge for checking the centricity of transverse holes in shafts comprises relatively adjustable feelers 7, 8 for engaging a shaft at opposed peripheral locations and means for mounting between the feelers, a transverse pin 12 adapted to engage a transverse hole in the shaft and of the same diameter as the hole. The two feelers 7, 8 and pin 12 are slidable and lockable in a groove 6 and in use the pin 12 is inserted in the hole to be checked and the feelers 7, 8 adjusted and locked in contact with the shaft, after which the gauge is removed and replaced with the pin 12 entering the hole from its other end, and the feelers interchanged relative to the sides of the shaft. If one feeler fouls the shaft it is moved and the clearance at the other feeler indicates twice the error in centricity of the hole. A further feeler 20 may be provided to enter a longitudinal keyway in the shaft with the shaft placed on the pin 12 and contacting the remote feeler 7, the feeler 8 being out of action, after which the gauge is removed and replaced with the pin entering the hole from its other end and the feeler 7 contacting the same side of the shaft as before. Any lateral adjustment of the feeler 20 to enable it again to enter the keyway will be measure of the orientation of the axis of the hole from a line at right angles to the line of the key-way.

Abstract: 639,214. Transmitting mechanical power; electromagnetic clutches. HARNISCHFEGER CORPORATION. June 24, 1947, No. 16672. Convention date, Oct. 25, 1941. [Classes 35 and 38 (iv)] [Also in Group XXX] An eddy-current coupling 15 between the input shaft 10 driven by a constant-speed prime mover and the driven shaft 51, such as the swinging motion of a mobile crane, is energized by a generator, driven by the prime mover, and having a drooping voltage characteristic, (e.g. a shunt generator), in order that the current in the inductive winding on the coupling may rapidly build up. Forward and reverse rotation of the driven shaft 51 is effected by selectively energizing a pair of couplings 15, 14 which respectively drive the output shaft through bevel gears 48, 50 and 54, 50. Each coupling has a member 16 fixed to the driving-shaft 10 and comprising a massive magnetic rim 17 having a peripheral groove 20 to contain the winding 21 and slotted transversely on the outer periphery with alternate deep and shallow slots 22, 23 respectively to form pole-pieces 24. The cylindrical eddy current member 46 carrying the bevel-gear 48 through radial member 45 is free to turn on the driving shaft 10 concentric with the rim 17 and is extended axially so as to be close to the inside face of an annular plate 39 secured to the member 16 and provided with slots 40, 41 to form pole-pieces 42, so that with thermal expansion of the eddy current member 46 the increase in the air gap between the pole-pieces 24 and eddy current member 46 is compensated by a decrease in the air gap between the pole-pieces 42 and member 46. The winding energized through slip-rings 29, 30 may comprise a plurality of coils series or parallel connected to suit the generator voltage which may be varied by a field resistance. Radial fins 25 formed integral with the driving member 16 assist cooling. Specification 639,215 is referred to.

A rail-terminus conveyer installation has a subsurface endless driving chain 28 passing at a crossover section below the level of a rail track 15 where there is provided a wheeled truck support surface at the same level as the track 15; the chain 28, which propels the wheeled trucks 9 by a pin 11 depending from the trucks 9 through a guide slot 10 into engagement therewith, travels in a loop having at least one portion parallel to the track 15 and at least one portion intersecting the track at the crossover section where the track rails 15 terminate on each side of the slot 10 and form part of the side walls thereof. The invention also resides in a crossover construction in which a drive line propels wheeled carriers across a rail track and comprises a guide slot extending across the track and separating each of the track rails which form a portion of the guide slot side walls and a drive line track located beneath the slot and the rails. The invention further resides in the combination of at least one surface rail track and a conveyer installation in which wheeled carriers equipped with a depending drive pin are propelled by a subsurface drive line which includes a surface level guide slot and an endless propelling member having a travel path below surface level in which one run is along one side of, another run is on the other side of, and a connection section runs across the rail track. The chain 28 is carried by trollies supported on wheels 25 running in subsurface channel, or Fig. 4 (not shown) angle, sections 23. Guide rods, Fig. 7 (not shown), may be provided in the lower corners of the channels 23 to maintain alignment of the chain 28 with the slot 10. The conveyer track may intersect the track 15 at right angles or at an acute angle. Ramps 16 are provided at the ends of the platforms 12, 13 which are of the required height above the rails 15. ______

The hopper has a spring- controlled cut-off plate 17 operated by the table 10 through links 17a. The drum 19 is adjustable vertically and carries a detachable die 25 for shaping the upper face of the tile. The drum is driven by a handle 20a or by a motor and in turn drives the table 10 by gear teeth 19a engaging a rack on the table. The drum is heated by a thermostatically controlled heater 26a and rotary brushes 26 are provided for cleaning the upper die. Piercing of the ribbed part of the tile which as shown is on the underside is.performed by a pin 29, Fig. 1A, on a sliding spring- returned carrier 28 mounted on the pallet support and moved relative thereto to pierce the tile by a depending member 27 which engages a block 15b set in the path of travel of the pallet. The pallet is apertured to receive the pin 29. Adjacent the block 15b ramps 15, 15a are provided up which the pallet runs to bring the tile clear of the table 10 and to enable the member 27 eventually to clear the top of the blocks 15b. The pin 29 is then returned by the spring 31. The member 27 is suitably pivoted to enable it to clear the block 15b on the return of the table 10. The moulded tile is finally placed in the container 32 from which it may be removed for brushing, colouring, glazing, &c.
