Abstract: 570,748. Treating carded webs. VARGA, A. June 25, 1943, No. 10299. [Class 120 (i)] [Also in Group XXX] In a driven endless conveyer band for use in combination with the machine described in Specification 444,043 in which foreign substances in a web or fleece 16 are crushed by pressure rollers 11, the band element 2 is mounted on two rollers 3, 4, the feed roller 3 being of much smaller diameter than the delivery roller 4 to avoid a sharp doubling- back action so that a web or fleece may gravitate automatically away from the band by its own weight on to a receiving surface. As shown, the roller trunnions 5, 6 are supported in bearings 7, 8 in brackets 9 adjustably or otherwise secured to the frame 10 of the pressure rollers 11, the roller 3 being driven by gears 12, 13, 14 from the lower roller 11. The bearings 7, 8 may be adjustable on the brackets 9 and the latter may be adjustable lengthwise for varying the tension on the band 2. Means for treating the web and/or the surrounding air with moist vapour, may be associated with the endless band, e.g. a steam pipe may be carried by the brackets 9 within the band 2 to allow steam to rise to the web through interstices on the band. The band may be of leather, textile material, &c. or of metal, wood, &c. bars held in close or spaced relationship. In a modification, the endless band is adjustably mounted to allow it to occupy different angular positions, the trunnions 6 of the roller 4 being carried by two pairs of arms, one pair mounted on the trunnions 5 and including an adjustable tensioning device and the other pair adjustably clamped to the frame 10.

Title: A process for preparing grafted vinyl alcohol-olefin copolymers
IPC: C08F261/04
Filed: 1965-03-11
Abstract: A grafted vinyl alcohol-olefin copolymer is prepared by irradiating a particulate or pulverulent vinyl alcohol-olefin copolymer with ionizing radiation and contacting the irradiated copolymer with (a) a conjugated diene or derivative thereof either alone or mixed with a vinyl or vinylidene monomer or (b) a solution containing the said diene or monomer mixture, in conditions in which the copolymer is slightly swelled and graft polymerization is effected but the particles of resin do not lose their particulate pulverulent form. The vinyl alcohol-olefin copolymer may be produced by partial or complete saponification of a vinyl ester-olefin copolymer. Suitable dienes are butadiene, isoprene and chloroprene.  Specified diene comonomers are styrene, acrylonitrile and methyl methacrylate.  The grafting may be carried out in an atmosphere of graft monomer vapour. In examples, vinyl alcohol-olefin copolymers with a degree of saponification of less than 100% are irradiated with an electron beam and contacted with graft monomers, in some cases in solution in methanol.  The vinyl alcohol-olefin copolymer and monomer or monomers are as follows: (1)-vinyl alcohol/ethylene copolymer, butadiene and acrylonitrile, (2)-vinyl alcohol/ethylene copolymer and butadiene, (3)-vinyl alcohol/ethylene copolymer, butadiene and styrene, (4)-vinyl alcohol/propylene copolymer and butadiene, (5)-vinyl alcohol/propylene copolymer, butadiene and acrylonitrile and (6)-vinyl alcohol/butylene copolymer and butadiene. The graft polymers may be blended with ungrafted vinyl alcohol-olefin copolymer and/or a polymer of the graft monomer or monomers.

Title: A process of and machine for fabricating articles of glass
IPC: C03B9/16
Filed: 1926-10-18
Abstract: 288,342. Miller, Inc., W. J., (Assignees of Miller, W. J.). Oct. 16, 1925, [Convention date]. Divided on 259,965. Blowing.-In a machine for making glassware, the parison moulds receive charges of glass during continued movement in an upright position past a charging point, and each mould is provided with a co-operating parison-forming element at its upper end, means being also provided for applying suction to effect a downward pulling on a charge of glass entering the mould to cause it to conform to the walls of the mould. After a charge has entered the mould, pressure may be applied from above to compact the glass and expand it in the mould. The mould table consists of a hollow hub 6, Fig. 2, which rotates about a hollow column 2 and is formed with a number of hollow arms 8, Fig. 3. The pipes for conveying compressed air to the moulds are led through the hol. low arms 8, and air for cooling the moulds passes through the spaces in the arms. Each set of moulds, with their operating- gear, is carried by a structure consisting of an upper frame 9 and a lower frame 10 which are bolted together. The whole structure, with the moulds completely assembled, can be lifted on to a pair of table arms 8, and when placed in position, ports in the mould structure register with corresponding ports in the arms 8 to which the air supply pipes are connected. The halves, of the parison mould are clamped to holders 36, Fig. 2, hinged on a pin 38 and opened and closed by a sliding plate 26. The plate is operated by a fixed cam and is connected with the mould holders by a spring dog 31, Fig. 3, which yields if the mould resists movement and thus prevents damage to the machine. The pin 38 is eccentrically mounted, as shown in Fig. 2, and may be turned to adapt it for variations in the length of the hinge members. The lower end of the mould closes abound the ring mould 79 which is carried by a transfer arm 53 that turns the parison over and transfers it from the parison mould to the finishing mould. In order to compact a charge of metal into the parison and ring moulds, suction is applied through the ring mould and compressed air through a mould cover which is brought down on to the open end of the parison mould. The mould cover is carried by an arm 86, Fig. 3, which is reciprocated vertically, and is swung to one side when raised in order to clear the parison as it turns over. The plug 122, for forming the initial opening in the parison, is moved up and down by a rod 121, Fig. 2, operated by a fixed cam 126. After a charge is compacted, the plug 122 is lowered and air is supplied through the ring mould to blow up the charge to fill the parison mould. The mould cover has a rounded lower end to shape the bottom of the parison, and it also regulates the length of the parison. Specification 156,569 is referred to. Reference has been directed by the Comptroller to Specifications 142,156 and 192,347.

IPC: H03B9/12
Filed: 1972-03-07
Abstract: 1379274 Avalanche diode oscillators PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 7 March 1972 [10 March 1971] 10527/72 Heading H3T [Also in Division H1] The oscillation frequency f of an avalanche transit time diode is chosen so that the transit angle (1d=distance which carries drift within the diode at the saturation drift velocity v), lies within the range 4 radians-5À2 radians. In this range, although the device operates at less than maximum power, the F.M. noise is low, being at a minimum value for ##4À6 radians. Oscillation frequency is determined partly by intrinsic diode parameters and partly by the relative values of a resistance R 2  and an impedance Z connected across the diode. In the Si diode shown the drift region lies within an n-type P-doped epitaxial layer 1 on an n<SP>+</SP>-type Sb doped substrate 2. Au on Pd electrodes are applied at each end of the diode, the Pd layer 3 contacting the layer 1 forming a Schottky barrier therewith. A Cu coding plate 9 is provided. The diode may alternatively be a P<SP>+</SP>N<SP>+</SP>N<SP>-</SP>N<SP>+</SP> Read diode (Fig. 2, not shown), in which avalanche breakdown occurs in the P-diffused n<SP>+</SP> region (23) adjacent the B- diffused p<SP>+</SP> surface region (24), and the drift region is constituted by a lightly Sb-doped nregion (21) epitaxially deposited on to a heavily Sb-doped n<SP>+</SP> substrate (22), The junction at which avalanche breakdown occurs may also be a heterojunction, and the Schottky barrier and pn junction of Figs. 1 and 2, may be replaced by a pn junction and a Schottky barrier respectively. Ge and GaAs are also mentioned as suitable semi-conductor materials.
