Filed: 1972-03-08
Abstract: 1388928 Splitting H F CARLSON 8 March 1972 [8 March 1971] 10830/72 Heading B5E A method of breaking a semi-conductor wafer 62 along a set of parallel score lines scribed on one side of the wafer comprises positioning the wafer intermediate a platen 56 having a surface carved in a direction perpendicular to the score lines and means 36 having a surface which is initially flat facing the platen with the scored side of the wafer in contact with the facing surface, and progressively conforming the facing surface and the wafer to the curved platen surface by moving the platen and means together and thereby first breaking the wafer about a central scribe line and then successively breaking the wafer about pairs of scribe lines symmetrically spaced from the central scribe line. In apparatus for carrying out the method, the facing means consists of a steel band 36 which is held over a pair of rollers 31 and has its ends 29 connected to the rods 22 of pneumatic piston-and-cylinder devices 18, 19 mounted on the frame of the apparatus. The platen 56 has a curved surface 58 and is mounted on the rod 48 of a further pneumatic piston-andcylinder device 41 also mounted on the frame. The wafer has two sets of scribe lines 63, 64 at right angles to one another and is placed on a carrier member having a base sheet 69 and an apertured guide sheet 71. A thin sheet 73 of paper is placed over the member and wafer and the assembly is positioned in a recess 88 in a slide 84 movable along a guideway in a plate 79 secured by a bracket 77 to the frame. The slide is movable by a handle 89 to position the wafer assembly between the platen and band so that when the device 41 is actuated to raise the platen, the wafer is pressed against the band which is held under tension by the devices 18, 19 and deforms to fracture the wafer first along the central score line and then simultaneously along pairs of score lines symmetrically spaced from the central line. After fracturing of the wafer along one set of the score lines, the slide is withdrawn and the wafer assembly rotated through 90 degrees by a handle 154 so that the wafer can be fractured along the other side of score lines. The operation of the apparatus may be automatically controlled and the movements effected by hydraulic electrical or mechanical means.

Title: Improvements in and relating to shedding-motions for looms for weaving multiple-ply fabrics
IPC: D03C1/10
Filed: 1929-04-08
Abstract: 309,381. Etablissements J. Laroche- Lechat Soc. Anon., and Montigny, L. April 7, 1928, [Convention date]. Dobbies.-In looms for weaving multiple-ply fabrics, each harness comprising chains 2, sectors 3, and ties 4, Fig. 1, is operated by a blade 5 having parts adapted to be engaged by cam-controlled bolts on carriages 7, 8 reciprocating in opposite directions without interruption and connected to rocking levers 10 operated by connecting rods 11 from a crank-shaft 12.

Filed: 1949-04-25
Abstract: 670,511. Floating structures. CENTRE NATIONAL DE LA RECHERCHE SCIENTIFIQUE. April 25, 1949 [April 30, 1948], No. 10960/49. Class 113 (ii).

Patent GB-352409-A (GB)
IPC: H04B3/40
Filed: 1930-04-07
Abstract: 352,409. Artificial lines. WESTERN UNION TELEGRAPH CO., 195, Broadway, New York, U.S.A. April 7, 1930, No. 10979. Convention date, April 12, 1929. [Class 40 (iii).] An artificial line for balancing an inductively loaded cable in a duplex system consists of T-sections having series resistance, series inductance, and shunt capacity, as described in Specification 158,262, [Class 40 (iii), Telegraphs, Electric], but the inductances are coupled by mutual inductance and point of connection of the shunt is adjustable. Eddy-current losses in the cable loading may be simulated by means of a comparatively high resistance shunted on the inductance. The Specification shows that if Zo be the characteristic impedance of the cable, a network of T- sections of the type shown in Fig. 1 can, by suitable choice of the constants L, R, C, when the mutual inductance is zero, be made to have an iterative impedance equal to Zo(1+z#+##<2>L)¢, where alpha, # are independent of L and # is the periodicity. If, however, L/4 be substituted for L/2 and the inductances be close coupled, an iterative impedance Zo(1+alpha#)¢ can be obtained, so that #=0 and the only correcting term left is independent of the inductance. The number of sections required for a given accuracy of balance has thus been reduced by the introduction of mutual inductance. If, now, the point of connection P be shifted from the centre of the coil by a fraction # of the total number of turns in the coil, the iterative impedance becomes approximately equal to {Zo(1+¢alpha#-¢##<2>L#<2>)-D#L#,} where # does not involve L, higher powers of # being rejected. If # has a sufficiently small value (such as 0À002) the term in # can be neglected and the term in alpha can, by adjustment of #, be made to cancel that in #, so as to give an accurate balance ; but a rough adjustment of # is practically sufficient. Eddycurrent losses in the cable loading may be simulated by means of resistive circuits coupled to the inductances, but alternatively the inductances of each section may be shunted by a resistance to simulate eddy losses, Fig. 4 (not shown). The inductance and series resistance may be in different arms of the sections as shown in Fig. 5. The capacity in each section may be divided between a large condenser C1 and small condenser C2, the latter serving for fine adjustment. The connection points of both condensers are adjustable for the purpose described above. For balancing a loaded cable of which the shore end is non-loaded, as described in Specification 246,429, [Class 40 (iii), Telegraphs, Electric], the artificial line may be in two parts: the part simulating the loaded portion has shunt resistance r but the part simulating the non-loaded portion has not, Fig. 6 (not shown).

Title: Improvements in and relating to production of monohalogen substituted phosphines
Inventor: HOFMANN EUGEN
IPC: C07F9/52
Filed: 1959-04-01
Abstract: A monohalogen-substituted phosphine of the formula R1R2PX in which X is a halogen atom and R1 and R2 are unsubstituted or substituted hydrocarbon radicals is obtained by reacting in a substantially inert organic solvent a compound of the formula R1R2PM in which M is an alkali metal atom, preferably lithium, with a halogenating agent, e.g. a chlorinating agent such as phosgene, phosphorus pentachloride, silicon tetrachloride, thionyl chloride, or chlorine itself. R1 and R2 may be the same or different radicals and may conveniently be alkyl or aryl radicals, e.g. phenyl radicals. The compound R1R2PM may be made by reaction in solution between an alkali metal and an appropriate phosphine.  In an example triphenyl phosphine and fine lithium wire are stirred together and dry peroxide-free tetrahydrofuran is then added dropwise.  The resulting mixture is allowed to cool to room temperature the excess lithium filtered off and a solution of phosgene in benzene is then added dropwise to form mono-chloro diphenyl phosgene which is recovered by distillation after first distilling off the tetrahydrofuran and benzene. According to the first Provisional Specification R1 and R2 may be alkaryl radicals and according to the second Provisional Specification R1 and R2 may be aralkyl, alicyclic, or unsaturated aliphatic or carbocyclic radicals.
