Abstract: 1,228,886. Ejecting concrete pipes from moulds. HUMES Ltd. 13 Sept., 1968, No. 43763/68. Heading B5A. [Also in Divisions B8, C7 and F2] A centrifugally cast reinforced circular section concrete pipe is cast within a slightly tapered steel mould 1, e.g. of # inch less diameter at the top than at the bottom whereafter, with the mould 1 vertically aligned, it is stripped from the pipe by vertically raising the mould whilst simultaneously preventing movement of the pipe by applying a downward force thereto. The reinforcement cage 8, of elliptical configuration, is located within the mould 1 by electrically insulated spacers and is provided with a conducting lead 9 whereby, after casting, an expandable ring is inserted into the mould to support the circular pipe and a direct current is passed through the pipe thereby causing electrolysis of the water in the pipe to produce a hydrogen layer between the pipe and the mould 1 to facilitate subsequent release. The vertical mould is then engaged, at diametrically opposed trunnions 5 thereof, by a pair of "V"- shaped elements 15, carried by a vertically displaceable pair of arms 14 of a fork lift truck 13, a locating pin 16 engaging a boss 6 vertically below a trunnion 5. The mould assembly is conveyed on the truck 13 to an ejection location wherein it is lowered to be supported on the ground upon legs 11 attached to a pipe support ring 3. Clamps 10 and 12 are then released to release the bottom pipe support ring 3 and an upper ring 4 to the latter whereof a downward force is applied by a hold-down cross 21 on the truck 13, until the initial release of the pipe has been effected by simultaneously raising the mould 1 by the truck arms 14. The hold-down cross 21 is vertically displaced by an hydraulic cylinder 22 and is pivotable into position above the mould 1 by a further hydraulic cylinder 20.

Abstract: 1,231,421. Programming counter. GENERAL ELECTRIC CO. 29 May, 1968 [21 June, 1967], No. 25807/68. Heading G4A. Setting of a selected stage of a programming counter determines how many steps a shift register should make. The programming counter is of binary gated type with five stages CFA-CFE. According to data registered in a P-field in elements B14, B15 the counter is set to specified starting points. At the start of a cycle (SCO1, clock pulse TCK1) stages CFB-CFE are reset while stage CFA is set. During this first clock pulse if there is an indication that the memory location of the control word is being used for the first time then gate 12 resets CFA. At sequence control state 3 (SCO3) the counter can be set to any one of four conditions: (a) If P = 00 gate 14 sets CFB, indicating 4 bytes of 6 bits and requiring the B- register 100 to step 6 times. (b) If P = 01 gate 15 sets CFC, indicating 3 bytes of 8 bits, and requiring the register to step 8 times. (c) If P = 10, then CFB - CFE remain reset, and the register has to step 12 times for each of the two bytes. (d) If P = 11 gate 16 sets CFD indicating that there is one byte of 24 bits. At time SCO4 the state of CFD is repeated in CFA over gate 10 or 13 as the case may be. Assuming that CFA is now at 0 (cases (a)-(c) above) then gates 17, 18 are enabled at successive clock pulses TCK1 to reverse CFE each time. The counter then operates in binary fashion from whatever point it was set, omitting binary 6, 7, 14, 15. An effective count is thus made of 10, 8 or 6 before gate 190 opens to set CFA to 1 again. While CFA is at 0 gate 102 sends a pulse HCE1 at every clock pulse to shift the contents of B-register 100 one step. When CFA return to 1 it updates the control word in known manner. In case (d) above CFA is set to 1 by gate 13 so that the B-register is not shifted.

Abstract: 1,231,713. Tungsten oxides; carbon. COMPAGNIE GENERALE D'ELECTRICITE. 2 June, 1969 [26 June, 1968], No. 27879/69. Heading C1A. [Also in Division H1] Tungsten oxide, WO 3 , may be prepared by heating tungsten powder in oxygen at 400‹ C. On heating WO 3  in hydrogen at 600‹ C., WO 2  is formed. The tungsten oxides are not stable and develop towards a formula WO x , where 2#x#3. The heating can be carried out so that a coating of the tungsten oxides is formed on the tungsten. Tungsten oxide may be deposited on a support of pulverulent carbon or tungsten or a thin sheet of C, Ti or Ta by impregnating the support with a tungstate, followed by a thermal decomposition under hydrogen. Alternatively, a " vapour plating " process may be used in which WCl 6  is volatilized by heating to 400‹ C., then cracked in the presence of the support to be coated by heating up to 700-800‹ C. using hydrogen as carrier gas.

Abstract: 1,239,376. Drying printed sheets. E. WEBER. 14 May, 1969 [15 May, 1968], No. 24576/69. Heading B6C. [Also in Division B8] A drying apparatus for printed sheets comprises a plurality of sheet carriers 9 mounted on an endless chain conveyer 4 which passes over a driven sprocket 2 and a sprocket 3 to define (a) an upper drying path, which extends from a loading position where a conveyer B feeds sheets from a printer A on to respective carriers 9 with the printed surfaces upwards, (b) a reversal position at sprocket 3, and (c) a lower drying path returning to the loading position; when the carriers reach a transfer position at the end of the upper path, a conveyer 11 lowers the sheets one by one to respective carriers which move into position at the beginning of the lower path, the sheets being pushed against the carriers and the conveyer 11 during the transfer operation by jets of air issuing from a tube 12 provided with nozzles 15a, 15, 15b so that sheet movement is controlled. Thus the printed surfaces of the sheets are never in contact with the carriers 9 during their movement, and the dry sheets can be removed from the carriers, when the latter return to the loading position, by a device F and can be fed by means of a conveyer F<SP>1</SP> into a box D or on to a shaking table. If, however, the sheets are dry by the time they reach the reversal position, removal can be effected by a device E<SP>1</SP> which stacks the sheets in a box E. At the reversal position suction device may be provided instead of or in addition to the tube 12 and its jet nozzles, and an embodiment featuring the latter modification is described with reference to Figs. 4 to 7 (not shown).

Abstract: 1,258,236. Measuring vehicle wheel alignment. FMC CORP. Feb. 18, 1970 [Feb. 19, 1969], No. 7751/70. Heading G1X. A projector 10 for mounting on the wheel of a vehicle and for projecting the image of reference indicia to indicate the alignment of the wheel is provided with a vertical reference pendulum 70 freely rotatable on a stub shaft 50 inside the housing 20 of the projector, the movement of the pendulum being damped by interaction of the field F of a permanent magnet 82 and a non-magnetic metallic plate 80 e.g. of aluminium carried by the pendulum 70 and suspended in the field F. The projection system comprises a lamp 22, condensing lens 24 and focusing lens 28 which serve to project a beam of light on to a screen (not shown). The projector is mounted on a vehicle wheel by virtue of the fact that it may be clamped to a shaft 12 carried by a clamp (not shown) on the wheel. The pendulum 70 carries a thin wire pointer 76 for use as a reference mark and secured to an intermediate wall 32 in the housing 20, there is provided a camber angle reticle 36 and a toe angle reticle 38 both of which have angular scales marked thereon the images of which together with that of the pointer 76 are projected on to the screen so that the appropriate angles may be read off. A third reticle 60 for measurement of caster angle is carried by an arm 52 pivotally mounted on the stub shaft 50 and having a slot engaged by a screw 56 which is tight enough to hold the arm 52 in a selected position but which permits an operator to adjust its position by means of a handle (not shown) projecting outside the housing 20. For measuring the caster angle of a vehicle wheel, the wheel is turned through a known angle in one direction from the straight ahead position and the arm 52 is moved to bring the zero on the caster reticle 60 into coincidence with the pointer 76. By turning the wheel through to a position at the same angle on the other side of the straight ahead position and noting the scale reading on the reticle 60, the caster angle may be determined.

In Fig. 1, a signal dependent on the size of a loop formed in a strip 11 passing between rolling mill stands 13, 15 is compared at 27 with a reference signal from a source 26 so that tension errors are corrected by automatic control of the speed of a motor 29 driving the rolls of stand 15. A signal dependent on rolling load from a load cell 33, modified for mill characteristics at 35, and a signal dependent on the position of screwdown 21 are combined at 39 to produce a signal, representative of strip thickness, which is compared with a reference signal from a source 40 so that thickness errors are corrected by automatic control of a screwdown motor 41. To prevent false correction of thickness during periods when the slower acting tension control is operating, all or part of the signal from load cell 33 is delayed by an adjustable resistance - capacity network 37.
