Abstract: 1,251,879. Transferring blanks. ENGEL INDUSTRIES Inc. 10 Oct., 1969 [11 March, 1969], No. 49896/69. Headings B3E, B3M and B3W. [Also in Division B8] A conveyerized edge processing apparatus for processing the edges of a rectangular sheet metal blank comprises a powered linear conveyer 12, a lateral abutment 25 adjacent the terminal end of the conveyer, an edge processing machine 47 laterally adjacent to the terminal end of the conveyer and having a line of feed 48 aligned with the lateral abutment 25, and including means 49 to grasp the blank, feed it through and discharge it laterally beyond the machine 47, means 61, 31 and 45 to move the blank laterally of and away from the conveyer when an edge of the blank squarely abuts the abutment 25, whereby to feed the blank along the line of feed 48 into the grasp of the edge processing machine 47. In operation a blank travels along the conveyer 12 until its forward edge squarely abuts the abutment 25. This activates two switches 27 which activate a circuit to supply fluid pressure to cylinders 43 and 63. The cylinder 43 acts quickly and raises ball domes 33 to contact the blank and facilitate its lateral movement while the cylinder 63 acts slowly and moves tab 65 to push the blank laterally. When the lifter means 32 are in the raised position, castors 70 deflect the blank downwards on to the conveyer roll 20 so as to keep it in contact with the conveyer 12. Thus as the blank is moved laterally the castors 70 and the conveyer 12 keep it squarely against abutment 25. When the blank reaches a switch 74, a cylinder 43 activates intermediate lifter 45 and the blank is fed through rolls 49. As the blank passes over a switch 75 the lifter means of a second conveyer 13 is activated after which it is lowered when the blank passes switch 7 so that the blank is lowered on to the conveyer 13. The blank passes to the abutment 28 of the conveyer 13, where the process of edge forming is repeated on the opposite edges after which the blank is passed to a discharge table 54. (For Figures see next page.)

The subject matter of this Specification is substantially the same as that described in the parent Specification, but the claims are directed to spaced three-dimensional frameworks, i.e. an upper and a lower framework, connected together by struts, e.g. 22c which can telescope within one framework, i.e. the upper framework, which framework can be fixed in position at different positions thereon by securing means. The cross-bracings and uprights are arranged so that complete collapsing of the  upper framework over the struts can take place.

Abstract: 1,258,398. Cutting glass. BRITISH OXYGEN CO. Ltd. 24 March, 1969 [27 March, 1968], No. 14713/68. Heading C1M. A glass workpiece is cut by heating a localized area of the glass by a non-transferred constricted arc produced by a plasma torch, and cooling the area by a stream of relatively cool gas ejected from'the torch so that the glass fractures due to thermal shock, the torch and glass being moved relatively so that the fracture extends along a desired line. The arc may be struck continuously or intermittently, and the cooling gas May emerge from a different conduit in the torch than the arc. In Fig. 1 an arc struck between electrode 4 and body 6 is extended by a stream of gas (e.g. Ar) through 12 to impinge on sheet 18 of glass while the torch moves in direction 20. Subsequently a stream of the same (but cool) gas exiting via 16 impinges on the heated sheet and causes a fracture. In Fig. 2 a torch for cutting a tube 22 is shown, wherein there is only one conduit in the torch, the arc being struck intermittently.

In examples, the above xanthonecarboxylic acids are prepared by (1) cyclizing a corresponding diphenyletherdicarboxylic acid; (2) hydrolysing the corresponding nitrile or amide; (3) reacting a 6-nitroxanthone-2-carboxylic acid with the sodium alcoholate to displace the NO 2  group; (4) splitting a methoxy group with AlCl 3 ; (5) etherifying an hydroxy group; (6) reducing a nitro group; (7) hydrolysing an MeSO 2 NMe group to NHMe, (8) oxidizing the 2-Me compound; (9) methylating an MeSO 2 NH compound, (10) hydrolysing the ester. The esters are prepared by standard esterification procedures.

Abstract: 1314024 Digital transmission systems; signalling by DC ULTRA ELECTRONICS Ltd 11 Sept 1970 [13 Nov 1969] 47290/69 Heading H4P Both data and clock pulses combined in a ternary signal, preferably RTZ, is transmitted over a two conductor transmission line 1, 2 by a pair of driver elements 6, 7 to a first differential comparator 8 giving an output representative of a first ternary state and second comparator 9 giving an output representative of a second ternary state and both comparator outputs representing the third ternay state with an OR gate delivering clock signals. The arrangement is stated to be uncritical of frequency or pulse width constancy and the bit rate need not be the same in each direction of transmission. Lines 1, 2 are separately pulsed by positive voltages corresponding to 1's and 0's respectively (see Fig. 5b, 5c, not shown) corresponding to signal pulses injected at D1 and gated by clock pulses P1 causing either receiver comparator 8 or 9 to give a corresponding negative output. Direction of transmission is controlled by a signal on C1 which prepares gates 11, 12 and inhibits receiving gates 29, 30 (or C2, 36, 37, 17 for reverse transmission). Diodes 15, 16, 38, 39 act as bias generators causing the -ve terminals to be about 1À4 volts more positive than the +ve terminal due to each line not in use providing a temporary bias source thus blocking noise below the bias threshold level. It is stated that reconstituted clock pulses P1 (IN) may be used to reconstitute data pulses D1 by clocking a shaft register into which SO1 and SO1 signals are passed; preferably however both SO1 and SZ1 signals are utilized, particularly for parity checking. The shunting effect of the low output impedance of the drivers at the receiving end, e.g. 13, 14 is eliminated by diodes 22, 23 and resistors 43, 44. The line conductors may be in the form of a twisted pair. The use of the arrangement may be extended by using coincident positive or negative pulses on the lines simultaneously and connecting an AND function between the lines at the receiving end but this is vulnerable to common mode noise. Another form of information can also be transmitted when it is not in use for the ternary RTZ signals or alternatively other information can be interposed between RTZ signals.
