Abstract: 833,327. Filters. SMITH, E. March 8, 1956 [March 10, 1955], No. 7018 /55. Class 46. Water, (e.g. drinking water), to be filtered is introduced by pipe 13 under a baffle 23 and passes upwards through a floating mass 20 of grains for example of polythene retained by a partition 11. The filtered water passes through nozzles 21 and out at 16. Cleansing is effected by passing water downwards from pipe 16 and withdrawing it together with floe through a pipe 25. The filter medium is at the same time agitated by rotating arms 27. The partition may be dispensed with, in which case filtered water is collected by a series of perforate pipes lying just under the top wall of the casing and communicating with the outlet pipe, Fig. 3 (not shown). Where the partition is provided the top of the casing may be open, Fig. 4 (not shown). In an alternative method of cleansing the medium is first agitated, after which the floe is drained away with or without a downward flow of water supplied through pipe 16. The polythene grains may be between one millimetre and one eighth of an inch in diameter and more than one size may be used.

Title: Lift truck with extensible mast assembly
IPC: B66F9/08
Filed: 1962-02-26
Abstract: 942,527. Masted lift trucks. CASCADE MANUFACTURING CO. Feb. 26, 1962, No. 7324/62. Heading B8H. In a lift truck provided with an upwardly movable mast section, a latch mechanism is provided to lock the mast section in a lowered position until the load carriage is raised to the top of the mast section after which the mast section is unlocked and the carriage is locked to the mast section. As shown, the mast includes a fixed section 26, comprising a base 36 supporting channel-section guides 32, a movable section 28 comprising channel section guides 40 connected by a top plate 44 and a cross-bar 46 and slidably mounted in the guides 32, and a carriage 50 provided with rollers 58 running in the guides 40. The carriage 50 is raised by an hydraulic ram 60 and chains 82, 84 which extend from an anchorage 80 on the ram cylinder 62, over sprockets 70 on a cross-head 68 secured to the ram piston-rod 66, sprockets 78 on members 76 secured to the cross-bar 46 of the movable mast section, and sprockets 74 on a frame 72 secured to the top-plate 44, to an anchorage 81 on the carriage 50. In operation, the carriage is raised to the top of the mast section 28 where it is locked and further extension of the ram 60 causes the plates 56 on the carriage to engage the top plate 44 and thereby pull up the section 28 at the same speed. The latch mechanism 86 comprises pairs of latch members 92, 94, Fig. 1, secured to rods 90, 91 journalled in the frame 72. Initially the mast sections are locked by engagement of a lug on the fixed mast section 26, in the recess 116 in one of the latch members 94 which is prevented from rotating by the latch members 92. As the carriage reaches the top of the mast section 28, a lug 110 on the carriage engages the recess 112 in one of the latch members 92 which is thereby rotated to release the latch members 94. As the carriage then begins to raise the mast section 28, the lug on the section 26 is disengaged from the latch member 94 which is thereby rotated to prevent rotation of the latch members 92 so that the carriage is locked to the mast section 28. Similarly, the latch mechanism prevents lowering of the carriage with respect to the mast section 28 until the section 28 is fully lowered. In another embodiment, Fig. 8 (not shown), an additional latch lug is provided on the ram crosshead which, as it rises, releases the movable mast section from the fixed mast section and is itself then locked to the movable mast section. During this time the carriage is moving up the movable mast section and when it reaches the top the lug on the carriage releases the movable mast section from the crosshead and is then locked to the movable mast section. In a further embodiment, Figs. 6, 9 (not shown), the latch mechanism is applied to a three-section mast.

Filed: 1957-03-06
Abstract: 798,459. Cartridge filling machines. ALITE MACHINES, Ltd. March 6, 1957, No. 7409/57. Class 9(1) [Also in Group XXIX] A hydraulic link for a powder filling machine has a cylinder 4 containing a driving piston 17, and a driven piston 20 with a column of liquid between them. The driving piston 17 is reciprocated and when the pressure of the liquid between the pistons reaches a value determined by the setting of an adjustable relief valve 40, liquid is forced past valve 40 to a tank 46. Hence the setting of the valve 40 controls the amplitude of stroke of, speed of, and pressure exerted on, piston 20 to suit different constitutions of powder, humidity conditions and sizes of receptacles. The piston 17 is reciprocated by a rotating cam 14 acting on roller 13, arm 9 and piston rod 7. On the return stroke, liquid is supplied from the tank 46 through a non-return valve 30 to between the pistons and the piston 17 is pulled back by a spring 16.

Title: Improvements in or relating to electronic digital computers
IPC: G06F17/17
Filed: 1964-02-21
Abstract: 1,063,014. Digital calculators. GENERAL PRECISION Inc. Feb. 21, 1964 [Feb. 21, 1963], No. 7425/64. Heading G4A. Electronic digital computing apparatus for obtaining the value of a function for a required argument value, uses the most significant digits of the required argument value to obtain by table look-up the values of the function for values of the argument bracketing said required value, and uses the least significant digits of said required value to perform an interpolation on these. The interpolation is linear. Values of a function of three variables are stored on a magnetic drum (12), and as the drum rotates, a first counter (17) is incremented. Whenever the first counter overflows, a second counter (58) is incremented and whenever this overflows a third counter (59) is incremented. The readings of the three counters are compared (18) with the most significant bits of the required values of the three arguments respectively. When all comparators (18) indicate equality, seven interpolation operations are done in turn as follows, each using bracketing values of the function gated into multiplicand registers (25, 26) from the drum (12) or from intermediate registers (74, 77) storing the results of previous interpolations. Each interpolation also uses the least significant bits of the required value of an appropriate one of the arguments, which are gated into a multiplier register (29) for this purpose. The contents of the multiplicand register corresponding to the lower argument value (25) are read (non-destructively) into a first accumulator (31). The bits in the multiplier register (29) are sensed and shifted out in turn low order first, each sensed bit causing adding (35) of the contents of the first accumulator (31) to those of the lower (25) or higher (26) multiplicand register according as the multiplier bit is 0 or 1 respectively. The result in each case is returned to the first accumulator (31) via an intermediate accumulator (36) with a one bit shift to low order, the shifted-out bit being inserted in the vacated portion of the multiplier register (29). As a modification, the initial transfer from the lower multiplicand register (25) to the first accumulator (31) may be accomplished by having an extra multiplier bit of 0 in the lowest order position, instead of using a special transfer path as above. In either case, the first accumulator (31) and the multiplier register (29) finally store the interpolation result and their contents are gated to an output in the case of the last interpolation. Otherwise, the contents of the accumulator (31) are gated to one of the intermediate registers (74 or 77) for use in succeeding interpolations. Functions of one or two variables may be evaluated with one or three interpolations respectively. Use in an aircraft flight simulator is mentioned.

Title: Metal coated articles and method of making same
IPC: C23C4/06
Filed: 1962-02-26
Abstract: A thermal shock-resisting coating for ferrous surfaces consists of a powdered metal having a coefficient of expansion different from that of the base metal, and a filler material selected from Al2O3, SiO2, and MgO also of different coefficient of expansion but in opposite degree to the powdered metal, said combination being so proportioned to provide a coefficient of expansion for the coating substantially equal to that of the ferrous base metal.  The mixture of powdered metal and binder oxide is mingled with a little methyl cellulose and water, and the paste is then extruded into rods, which are applied as a coating by a flame gun.  For example, powdered metals (325 mesh) which have greater coefficients of expansion than iron and steel, e.g. Al, Al alloys, Mg, Cd, and Pb are mixed with silica; nickel (only slightly greater) with alumina; chromium, beryllium and titanium (which are less than steel) with magnesia.ALSO:A thermal shock-resisting coating for ferrous surfaces consists of a powdered metal having a coefficient of expansion different from that of the base metal, and a filler material selected from Al2O3, AiO2, and MgO, also of different coefficient of expansion but in the opposite degree to the powdered metal, said combination being in such proportions to provide a coefficient of expansion for the coating substantially equal to that of the ferrous base.
