Abstract: 1,228,325. Bonded non-wovens. KENDALL CO. 16 Oct., 1969 [25 Nov., 1968; 9 June, 1969], No. 50907/69. Heading D1R. A bonded nonwoven fabric is prepared by applying to the surface of an unbonded or weakly bonded fibrous web 10 of textile length fibres e.g. rayon or continuous filaments of e.g. polypropylene an aqueous dispersion of a polymer binder 18 containing in suspension ultra-short fibres of length between 50 and 300 microns e.g. wood pulp from a flooder box 16. The polymeric binder may be a polyacrylic binder, polyvinyl resin or butadienestyrene polymer. The web 10 is advanced to a suction box 29 and then passed to screen 26 where it is dried by I.R. heaters 32 to set the binder. The layer of ultra-short fibres 44 are disposed substantially horizontally and penetrate into the web but are more highly concentrated at or near the surface of the web. Alternatively an aqueous suspension of the ultra short fibres may be applied to the unbonded web and a dispersion of a polymeric binder subsequently applied. Successive applications of ultra-short fibres suspended in binder dispersion may be applied wherein the fibres in the initial application are shorter than in subsequent application. In a further embodiment, the ultra-short fibres may be coated with a polymeric binder and applied to the unbonded web from an aqueous suspension and the web subjected to treatment with the same or different binder.

Abstract: 1,264,788. Gas turbine engine fuel systems. JOSEPH LUCAS (INDUSTRIES) Ltd. June 12, 1969 [March 15, 1968], No.12751/68. Heading F1G. [Also in Divisions G2-3] In a system for controlling the pressure rise across the compressor of a gas turbine by varying the fuel flow, the pressures upstream and downstream of the compressor are applied to opposite ends of a Venturi 10 dimensioned such that flow therethrough is supersonic. The desired pressure ratio will produce a standing shock wave at 11, and variations in the position of the shock wave are sensed via line 17 connected to one control port of a bi-stable or proportional fluid amplifier 12 whose other control port is connected via restriction 18 to a downstream tapping. The amplifier acts to control fuel flow such as to maintain the position of the shock wave at 11, and thereby maintains the pressure ratio constant. The Venturi is rectangular and the set point is adjusted either by adjusting the position of tapping 11 or by adjusting a restriction upstream of the Venturi.

Abstract: 1,267,170. Indenoquinolizine derivatives. BIOREX LABORATORIES Ltd. 30 Oct., 1970 [3 Nov., 1969], No. 53787/69. Heading C2C. The invention comprises novel indenoquinolizine derivatives of the Formula III wherein R is OH, acyloxy or acylamino, 1,2,5,6,- 10a,10b - hexahydro[3H,10H]indeno[7,1,2 - hij]- quinolizine-3,10-dione and 10-oximino-1,2,5,6,- 10a,10b - hexahydro[3H,10H]indeno[7,1,2 -hij]- quinolizine-3-one. The above dione is obtained by cyclizing ethyl 4-oxo-1,3,4,6,7,11b - hexahydro[2H]benzo[a]quinolizine-1-carboxylate or the corresponding acid, obtained by hydrolysing the aforementioned ethyl ester, which is made by the hydrocyclization of diethyl α-3,4-dihydroisoquinolyl-1-glutarate resulting from the reaction of ethyl acrylate with ethyl 1,2,3,4,-tetrahydroisoquinolylidene-1 -acetate. The 10-oximino derivative is prepared by reacting the 3,10-dione with hydroxylamine. Reduction of the 3,10- dione gives compounds of Formula III above in which R is OH, and this compound may be converted into the corresponding 10-acyloxy derivative by reaction with acid anhydrides. Compounds of Formula III above in which R is an acylamino radical are obtained by acylating 10- amino - 1,2,5,6,10a,10b - hexahydro[3H,10H]- indeno[7,1,2-hij]quinolizine, resulting from the reduction of the 10-oximino compound referred to above.

Abstract: 1317336 Making staples McCAIN MFG CORP 7 Aug 1970 38298/70 Heading B3A [Also in Division B4] Means for feeding a continuous length of wire e.g. in a staple forming stitcher head of a signature stitching machine comprises a driver bar 54<SP>1</SP> coupled to and reciprocable with a slide (27), (Fig. 1, not shown), driven by an oscillatable lever (20), a channel member or bar 50, and a latch 55 slidable transversely of the bar 50 in grooves 50S. A spring 52 biases the leg 55L of the latch into engagement with the edge of the driving bar 54<SP>1</SP> provided with notches 54U<SP>1</SP>, 54H, and 54L<SP>1</SP>. An anvil block 48 rigidly secured to the bar 50 and overlying latch 55 includes a slot 44S in which a gripper jaw 44 is slidable. The spring 52 protrudes through an aperture in the jaw 44. Vertical movement of the bar 50 is limited by the anvil block 44 engaging the upper or lower edge of a window 43W. In operation with the bar 50 in its upper position (Fig. 4), the bar 54 will continue upward movement until the leg 55L of the latch engages in notch 54L<SP>1</SP>, wire then being gripped between the jaw 44 and an opposed surface of the anvil block. Downward motion of the driver bar will also effect similar motion of the bar 50. When the bar 50 reaches its lower position (Fig. 5) the latch will be cammed by means (not shown) to release the leg 55L from notch 54L<SP>1</SP> and the jaw 44 will thus be moved to a "non- grip" position. Continued downward movement of the driver bar 541 brings the notch 54U<SP>1</SP> into coincidence with the leg 55L. A friction coupling between the bars provided by a spring biased pin (not shown) will effect simultaneous upward movement of the bar 50 with the bar 54<SP>1</SP>, and the leg 55L will be urged by spring 52 into the notch 54U<SP>1</SP> so that the jaw is retained by the notch 54U<SP>1</SP> in a "non-grip" position. If wire is not to be fed on a downstroke of the driver bar and bar 50, e.g. when a caliper senses that a signature is of incorrect thickness upward motion of the driver bar is stopped by means (not shown) at a position in which the leg 55L will engage with notch 54H. With the latch in this position the jaw will be in a "non-grip" position so that on the next down stroke the wire will not be fed.
