Abstract: <PICT:0624377/III/1> <PICT:0624377/III/2> <PICT:0624377/III/3> <PICT:0624377/III/4> <PICT:0624377/III/5> <PICT:0624377/III/6> <PICT:0624377/III/7> A machine for applying facings to building blocks and the like comprises means for applying the facing, an input conveyer to carry blocks through the applying means in end to end abutting relationship and a driven roller, belt or chain above this conveyer to hold the blocks to it.  In a modification, the roller is replaced by, or the machine incorporates in addition, a second conveyer to carry away the faced blocks, this conveyer being driven at a greater speed than the first so as to separate each block from the succeeding one.  Referring to the drawings, a conveyer 14 leads in blocks B to conveyer 15 which carries them with the help of roller mechanism 13 through the facing portion 11 and 12 of the machine, after which they are removed by conveyer 16.  Belt 14 is driven by pulley-wheel 20 mounted on a driving shaft 21 while the chains 22 of conveyer 15 are driven by wheels 24 concentric with and on shaft 21 carrying pulley 20, but driven at a different speed.  A similar arrangement is used for belts 15 and 16 on shaft 25.  Fig. 6 shows an arrangement for this differential driving mechanism.  Chain-wheels 24 are mounted on shaft 21, but two pulleys 20a and 20b carrying belt 14 are mounted on sleeve 20c freely rotatable on shaft 21. Sprocket-wheel 20d is driven by chain 20e from driving shaft 20f which may carry a slipping clutch device 20h.  The feeding roller mechanism 13 (Fig. 5) comprises two rollers 36 mounted on shaft 37 supported in bearings 38 on arm 39 pivotally supported on shaft 40 fitted to frame of machine.  Adjustable springs 41 urge rollers 36 into engagement with blocks B.  Shaft 37 is driven by pulley-wheels 42 and 43 and chain 44 from driven shaft 40.  The blocks are held on the conveyers by guide rails 18 and 19.  The facing material is applied from hopper 11 containing an agitator 29 driven on shaft 30, a pack roller 31 driven on shaft 32 and an adjustable finishing knife 33 to level off the facing.  Near the extreme output end, spring-loaded scrapers remove surplus facing material. In an alternative arrangement the block facings are separated by a vertically reciprocating knife operating beyond the hopper (Figs. 7 to 9).  The knife 50 is mounted on carriage 51 running in inclined track 52.  Spring-loaded hinges 53 on carriage 51 engage cavities of hollow blocks B and hence movement of blocks draws knife 50 down to sever facing.  Then pivoted detents 54 are raised by cams 55 releasing fingers 53 when carriage moves back by action of spring 56 until fingers 53 engage cams 57 which re-insert them in next hollow block.  The machine may be used for facing blocks prepared according to Specification 595,232, [Group X].

Class 68(i) [Also in Group XXV] In a coal cutting chain comprising links connected by ball and socket joints, each ball is provided with a shank which extends towards the next link of the chain and each socket consists of a recess, extending inwardly from a lateral face of the link which carries it, and connected by a slot with the end of the link to permit assembly of each ball in the socket of the next link by passing the shank through the slot, the recess being closed by a plug which fits it outside the ball. In one form, Figs. 1 and 2, each link is formed of cylindrical ears 12, 13, which fit in the hollows between the teeth 14 of the sprocket 15, bridged by a portion 16 and a web 17, which lies in a space between the two side portions forming each tooth. Each ear is drilled out as at 18 forming sockets to accommodate the ball members 20 which have connecting shanks 19 passing through slots 21 beside the sockets 18. When the ball members 20 have been inserted, the sockets 18 are stopped by plugs 22 retained by peening over the metal ears or by light welding. The sockets are also machined with slots 23, 24 and 25 to permit the chain to bend. The cusps 26 formed by the slots provide increased bearing surface for the balls. The picks are carried by bosses 30 and the links also carry projections 33, 34 which engage in the guides of a chain jib. In another form, Fig. 4, the sprocket has teeth only between the pick-carrying links and each link is formed by two end socket portions 42, 43 of case-hardened steel which have abutting T-shaped projections 44, 45 extending upwardly from the base of the link. A roof portion 47 of the pick-carrying boss fits over the projections 44, 45 and the whole is retained by a rivet 48: In other similar forms, the abutting projections are of dovetail section, extending upwardly or transversely across the link. Specifications 21948/03, [Class 24], and 626,080, are referred to.

Filed: 1961-09-11
Abstract: 998,073. Selective printing. AUTOGRAPHIC BUSINESS FORMS Inc. Sept. 11, 1961 [July 3, 1961], No. 32581/61. Addition to 968,593. Heading B6F. Record-card controlled series printing.-The method of printing a series of bank cheques &c. in which a web 56 is pre-printed with common matter and then printed with unique matter at printing positions 52 and/or 53 as described in in the Parent Specification is improved in that after a predetermined number of cheques have been printed the feeding of the continuous web is stopped, the printers again set to the unique matter required for the next series or group of cheques, starting the feed again, and so on with further groups of unique matter. This matter, as described is derived from punched cards by a reader 50 and entered in a data storage 51. Special feed-roller rotation.-The position at which printing occurs is determined by the initial placing of the web on the pin wheel tractor 57 and a disc 69, which is geared to a shaft 67 driven from an electric motor 64. When the lobe 69 engages switch 70 the impression mechanism is operated. The distance apart of the two impressions from the printers 53, 52 may be varied under control of the data storage by arcuate movement of the switch 74 mounted on an arm 74a rotated by wormgearing and a motor 76. Line-spacing.-The distance between the printing by one line printed by printer 53 and that line printed by printer 52 may be varied by altering the speed by unit 63. Pin-tractor web feeds: cutting.-The web 56 is fed by two tractors 57, 58, a change-speed unit 63 and an electric motor 64. After the printing the perforations are longitudinally cut off and cheques cut transversely from the web. Web-tensioning arrangements.-To avoid slack in the web 56 the two tractors are coupled together by gearing 65. Counting.-The number of cheques &c. to be printed with one kind of unique matter is predetermined by the punched card and the data storage effects a drive to a motor 88 which, through a worm drive presets a contact arm 83 of a counter 78. There is a ratchet-and-pawl mechanism 81, 82, Fig. 2, coupling the arm 83 to the drive shaft 67 so that as each cheque is printed the arm restores one step. At the end of the required number of printing the arm 83 opens a switch 84 and the motor 64 is stopped.

Abstract: 627,236. Valve circuits. GENERAL ELECTRIC CO., Ltd., and GRIMBALDESTON, W. Nov. 4, 1946, No. 32653. [Class 40 (v)] A detector circuit for use as a sidetone monitor at a C.W. telegraph-transmitter or as a detector in a C.W. telegraph-receiver comprises a valve adapted so that the anode and cathode act as a diode rectifier, a source of A.F. oscillations is connected between control grid and cathode of the valve which is biassed so that it conducts only on positive half-cycles of the A.F. oscillations a sound-reproducer being operated by the A.F. voltage appearing in the load circuit of the valve. In the Fig. the C.W. signal is - applied to terminal R.F. to produce a voltage across the anode and cathode of valve T which acts as a diode detector. The valve is biassed by the resistors R2, R6 connected across the. H.T. supply so that when switch S is open the valve is wholly or partly.cut-off. - During the positive going half-cycles of the locally-generated audio signal applied at terminal A, the valve conducts and a carrier voltage across inductor L produces a voltage across the diode load R and after filtering is heard in the headphones connected across terminals M. As the detector input is untuned it is unaffected by drift of the carrier frequency. When switch S is closed the bias is removed from the valve and the circuit may be used as a detector of a modulated incoming carrier wave.

Title: Beneficiation of manganese silicate ores
IPC: C01G45/02
Filed: 1957-10-21
Abstract: Manganese silicate ores are ground to minus 30 mesh (Tyler) and roasted in air at 500-900 DEG C with NaOH, KOH, Na2CO3 or K2CO3 in amount sufficient to provide two atoms of the alkali metal per atom of manganese in the ore.  Suitable ores are Rhodanite, Bementite and especially garnet ores containing Spessartite Mn3Al2 (SiO4)3.  The product when using the latter is a dark, powdery pyrodusite disseminated throughout a white granular alkali metal-aluminium silicate from which the former can be separated by conventional methods such as tabling, flotation or acid leaching.  In an example, a quartzite rock containing in addition to spessartite, scheclite (CaWO4), ansenopyrites, pyrites and silica, was first treated conventionally to remove scheclite and pyrites and then ground with dry NaOH, moistened, reground and roasted at 800 DEG C. for 4 minutes.  It is stated that as the above ratio of alkali metal to manganese is exceeded, the products other than manganese dioxide first become soluble and then watersoluble manganates are formed.

Filed: 1964-08-14
Abstract: 1,268,341. Aerials. CSF COMPAGNIE GENERALE DE TELEGRAPHIE SANS FIL. 14 Aug., 1964 [9 Sept., 1963], No. 33347/64. Heading H4A. A U.H.F. antenna is formed of a parabolic reflector illuminated by a radiating source, e.g. a wave guide horn, offset relatively to the focus of the reflector. To produce a plane reflected wavefront, phase distortion is corrected by means of either a second, shaped reflector or a lens, mounted in the path of the reflected radiation. Where the second reflector is adopted, polarized radiation is employed and the reflectors employ plane arrangements of parallel conducting wires. A given ray is reflected at a first incidence by the wires while at a second incidence, following reflection, the plane of polarization is changed and transmission takes place through the reflector. Interruption of the transmitted beam by the reflector system is thus prevented.
