Title: Improvements in or relating to devices for piling sheets delivered from machines
IPC: B65H29/22

Abstract: 417,952. Sheet-delivery apparatus. VICKERS-ARMSTRONGS, Ltd., and DANIELS, F. K., Vickers House, Broadway, Westminster. April 26, 1933, No. 12202. [Class 100 (i).] In a sheet delivery or piling apparatus, the sheets are added to the bottom of the delivery pile by first applying one edge of the sheet to the underside of the pile and then gradually moving successive portions of the sheet into contact therewith, whereby the sheet is added without relative sliding movement between the sheet and the pile. In one form, the pile 26 is supported on a series of rollers 12 moved as a whole beneath it, the sheet 28 to be added being projected from below, between adjacent rollers, and spread along the underside of the pile by the movement of the rollers. The rollers 12, Fig. 2, are rotatably mounted on spindles 10 carried by endless chains rotated from a mainshaft 6, Fig. 3, the spindles 10 also carrying supporting rollers 13 running in guide-grooves in the side frames 2, 3. Fixed to one end of each roller 12 is a sprocket-wheel 14 with a pitch-circle equal in diameter to the roller and engaging an endless-rack 15. The sheet 28 is delivered laterally on to a table 17 beneath the upper run of the rollers 12 and is thereafter moved by a reciprocating pusher 18 into a space 27 formed between a pair of rollers 12 by the omission of a roller, an inclined part 26 of the table facilitating this. The rollers raise the sheet to the bottom of the pile and by their rotary motion spread the sheet along the underside of the pile. The pusher 18 is fixed to a rod 19 reciprocated from a cam 25 on the shaft 6 through a lever 22. In a modified form, the rollers 12 are carried by a reciprocating- carriage, and the rod 19 is reciprocated from the carriage by an arm on the carriage engaging stops on the rod 19.

IPC: B01J41/14
Filed: 1964-03-24
Abstract: A selective adsorbent for metaloxy or metalloid oxy anions comprises a cross-linked alkenyl aromatic polymer to the aromatic nuclei of which are bonded numerous polyol ether groups of formulae -CnH2n-O-Z or (-CnH2n-O-)2Z where n is 1-4 and Z is a polyol substituent group derived from sorbitol, mannitol, dulcitol, talitol, arabitol and/or ribitol.  The adsorbent may be a styrenedivinylbenzene copolymer to aromatic nuclei of which sorbitol ether groups are attached via methylene groups.  The adsorbent may be made by reacting a cross-linked alkenyl aromatic polymer containing quaternary ammonium groups or sulphonium groups, e.g. polymeric vinylbenzyl dimethylsulphonium or trimethylammonium chloride, cross-linked with divinylbenzene, with the alkali metal salt of the above polyols, or with the polyol in the presence of an alkali metal hydroxide in proportion to the ion exchange capacity of the resin.ALSO:Metal oxy or metalloid oxy anions are removed from aqueous solutions by contacting with an unsoluble adsorbent which comprises a cross-linked alkenyl aromatic polymer to the aromatic nuclei of which are bonded numerous polyol ether groups of formulae -CnH2n-O-Z or (-CnH2n-O-)2Z where n is 1-4 and Z is a polyol substituent group derived from sorbitol, mannitol, dulcitol, talitol, arabitol and/or ribitol.  The oxy anions are borate, gallate, stannate, plumbate, arsenite, germanate and tellurate, and may be a mixture thereof.  In examples borate was adsorbed from an aqueous solution containing NaCl and Na2B4O7. 10H2O acid from an aqueous solution also containing magnesium chloride; TeO4 = from an aqueous solution of K2TeO4.2H2O; arsenite from an aqueous solution of Na2As2O4 and Na2SO4; and SnIV, GaIII and PbIV oxy anions were adsorbed from an aqueous solution containing Na2SO4, ZnSO4, NaOH, stannate, plumbate, gallate, selenate and arsenate.

[Also in Group XXIV] In a fork lift truck the vertical guide frame together with the lift carriage and fork is guided by a linkage mechanism for straight line movement transversely of the truck. The guide frame 35 is supported by a beam 25 which is constrained to move in a horizontal plane by a pair of pivotally-connected links 22, 24, pivoted to the truck chassis at 21, and to the beam at 99; and which is also constrained to move in a vertical plane by a pair of pivotally connected links 27, 28 pivoted to the truck chassis at 127 and to the beam at 29. To carry the linkage past its dead centre position in which links 22, 24 are aligned, a non-rotatable sprocket 30 is connected by a chain 32 with a sprocket 31 rotatable with link 24. The links are of hollow box construction, and within the link 27 is the actuating mechanism (not shown) which comprises an hydraulic thrustor, the cylinder of which is rigidly secured to the link, and the piston-rod of which carries a rack engaging a pinion freely rotatable with respect to the link 27, but rotatable with the link 28. In a modification (Fig. 5, not shown) the guide frame 35 is pivoted to the beam 25 for movement about a vertical axis into positions in which the fork faces forwardly or to the left or right side of the truck. Specification 774,481 is referred to.

Title: Improvements in demodulators for pulse code modulation systems
Inventor: LEVY MAURICE MOISE
IPC: H03M1/00
Filed: 1949-05-16
Abstract: 686,535. Pulse code mediation circuits. GENERAL ELECTRIC CO., Ltd. June 23, 1950 [May 16, 1949], No. 13009/49. Class 40 (v). [Also in Group XL (b)] The demodulator for a pulse code signal comprises a damped oscillatory circuit, resonant at a frequency equal to, or an integral multiple of, the recurrence frequency of the code pulse intervals, the code pulses being applied to the circuit to produce trains of oscillations of exponentially diminishing amplitude and the voltage across the circuit being sampled at or later than the last code pulse interval of the signal, and at or near a crest of the output oscillation, to produce a pulse of amplitude dependent upon the sum of the amplitudes occurring at the sampling instant. The oscillatory circuit may be replaced by a transmission line, or delay network, having constants such that a pulse applied thereto is reflected between its ends to produce at output terminals pulses of progressively diminishing amplitude and of a recurrence frequency equal to, or an integral multiple of the recurrence frequency of the signal code pulse intervals. The binary pulse code groups from radio receiver 25, Fig. 7, are applied to the damped oscillatory circuit 26, the oscillations produced across which are applied to the control grid of valve 30. Each successive positive half-cycle of each damped oscillation is arranged to have half the amplitude of that of the preceding half-cycle. The valve 30 is non-conducting except when a gating pulse from circuit 31 is applied to its suppressor grid. The gating pulse for a 5-unit code occurs in the middle of the sixth positive half-cycle produced by circuit 26 in response to a pulse in the first code pulse interval of a pulse code signal. The resulting amplitude modulated pulses at output terminal 34 are fed to the signal reproducer through a low-pass filter. An oscillatory circuit 35 may be connected in series with circuit 26 and tuned to the third harmonic of the resonant frequency of circuit 26, to flatten the tops of the waveform produced by the latter. A substantially rectangular waveform may be produced by adding further damped oscillatory circuits harmonically related to circuit 26. In a second embodiment, the transmission line 39, Fig. 8, terminated at 40, replaces the resonant circuit, arranged as hereinbefore described. Specification 683,820 is referred to.
