Abstract: 1,178,600. Non-woven fabric; paper. KALLE A.G. 31 Oct., 1967 [2 Nov., 1966], No. 49454/67. Headings D1R and D2B. Fibrous fleeces are reinforced by impregnation with a binder liquor including a defoaming agent removing excess binder and drying by a dielectric heating process. The process prevents migration of the binder or swelling of the fleece. The defoaming agent may be a higher aliphatic alcohol; e.g., butanol, isoamyl alcohol and ethyl hexanol; esters, e.g., of lauric and oleic acid with mono-or poly-hydric alcohols such as ethylene glycol and glycerol; and silicones. The defoaming agent can be diluted in gasoline or dispersed in water with emulsifying agents, e.g., sulphonates, before it is added to the binder liquor. The binder liquor can be latices or aqueous dispersions of natural or synthetic gums or resins, e.g., carboxylated butadiene-acrylonitrile copolymer, polyvinyl acetate or polystyrene. The fleece can be made of natural, synthetic e.g. polyester, or inorganic fibres, or mixtures thereof by carding, air-laying or paper manufacturing techniques. The fleece can be needled or shrunk prior to impregnation.

Title: Improvements in or relating to printing mechanisms
IPC: G06K15/07
Filed: 1964-12-07
Abstract: 1,049,820. Selective printing. INTERNATIONAL BUSINESS MACHINES CORPORATION. Dec. 7, 1964 [Dec. 17, 1963], No. 49618/64. Heading B6F. [Also in Division G4] In a high-speed printer operating from the output of a computer, a continuously driven type wheel 27 is mounted on a hanger 30 which is rocked by a cam 32 drivingly clutched for a single revolution at any selected one of a plurality of times within a type-wheel cycle so that a selected character on the type wheel is forced against a paper 25 on platen 22. Although a single print wheel may be employed for printing on a tape, as described, the printer comprises 120 type wheels so that a line of characters may be printed at a time. Each of the type-wheels 27 is continuously rotated by a cylindrical gear 28 and each individually mounted on a hanger 30. The selected characters (see Division G4) causes the operation of an energizing signal to be applied to a print magnet 36 one of which is provided in each column position. A slide 92 is moved which pivots a knock-off lever 86 clockwise: this allows a print clutch latch 80 to pivot counter-clockwise so that a print clutch dog 72 is pulled by a spring 74 about a pivot 73 whereby the hanger engaging cam 32 is clutched to a continuously rotating twelve-tooth reamer 70. The reamer 70 has teeth disposed on spirals having an angle of 7 degrees relative to the axis. The reamer rotates at 400 r.p.m., cam 32 engages a follower 66 on the type-wheel hanger 30 and thus swings the type-wheel to effect printing. Since the reamer 70 makes four revolutions to one revolution of the typewheel the electrical control determines in which -revolution the swinging of the hanger 30 occurs. After printing the L.H. end of the dog 72 is arrested by the now released latch 80 and the print cam 32 is held stationary between a print cam detent 76 and the print latch 80. Electrical control.-Signals to determine the position of the type-wheels which are fed to a comparitor (see Division G4), are generated by a code wheel (42, Fig. 2, not shown) containing forty-eight radially symmetrical binary patterns (43) and an outer radius clock track (45). The code wheel (42) is a solid disc with perforations corresponding to the binary code and a single light coacts with a number of sensors (48) to provide the comparitor (40) with signals. Type-wheel construction.-The type-wheels 27 are formed so that the sides of type-faces 60 are cut as gear-teeth. Cleaning type-wheel.-A brush 61 engages the type-wheels to clean them during rotation.

Abstract: 1,127,439. Welding by pressure. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 23 Nov., 1965 [26 Nov., 1964], No. 49664/65. Heading B3R. [Also in Division H1J Wire connections between closely spaced electrodes on a semi-conductor body and associated conductors are made by stretching a wire between two relatively movable members, severing the stretched wire at a weakened point, then moving at least one of the members with the severed wire projecting from it to a position where the end of the wire is in register with an electrode and effecting bonding. In a preferred arrangement, Fig. 8, clamp 23, 24 is closed on gold or aluminium wire 22, 5 to 30Á thick drawn from the reel. Relatively slidable members 25, 29 are then moved close together, jaws 9, 10 closed on the tensioned wire and the clamp released. After weakening the wire at a point between the jaws by notching, H.F. heating or sparking the members are moved apart to the limit allowed by stop 31 to break the wire and achieve a preset gap between the broken ends. The entire assembly is then moved a fixed distance beyond the clamp which is then closed and the wire severed at the clamp. The semiconductor device has already been set up under a microscope with two electrodes on the semiconductor body and associated header wires aligned. After moving the assembly to a position where the wire ends overlie the electrodes and header wires a thermo-compression bonding tool is brought up and the wire bonded to the electrodes and header wires in a single operation. The process is then repeated on another device.

Abstract: 1,058,719. Rolling. UNITED ENGINEERING & FOUNDRY CO. Dec. 17. 1963 [Dec. 28, 1962], No.49692/63. Heading B3M. [Also in Division B8]  Billets from a rolling mill, after being sheared to length, are conveyed along roller tables 16 and 17 on skewed rollers 18, to urge the billets towards a centre guide strip 21, and are then either deflected to one or other of the tables 16 and 17, or are allowed to continue over a roller table 43 to a channel 46 where they are frictionbraked and lifted clear of the channel on to a stacking site. Billets which have been deflected on to the driven rollers 19 of the tables 16 and 17 are braked by the rollers and stopped  by retractable abutments 23. Once a pack of billets is thus formed, it is conveyed along a driven run-out table 24. The level of the rollers  19 is lower than that of the rollers 18 to encourage quick lateral shifting of the billets. The deflector 25 is formed with deflector beams (38) and (39), (Fig. 4, not shown), integra with levers (34) and (35), which are pivotable by means of piston cylinder arrangements (36) and (37) about a common axis (33). Raising of the appropriate deflector beam (38) or (39) allows a billet to continue adjacent the centre guide strip (21) to the channel (46). The channel (46), (Fig. 8, not shown), is supported by two columns (53) which are vertically guided by rollers (54). Actuation of a pistoncylinder arrangement (64) rotates a shaft (62) anti-clockwise by means of a lever (63) and causes arms (59) to raise the columns (53). When the channel (46) reaches a desired height, rollers (67), provided on levers (66) attached to the columns, contact an abutment (68) to cause rods (65) to tilt the channel and then eject a billet on to inclined slideways (69) leading to a store (71). Test or scrap billets may be allowed to pass the deflector for storing at (71), the deflector being operated manually or automatically for this purpose. For automatic control, the lengths of the billets after shearing are measured, using photo-electric cells, and short billets, for example, cause the deflector beams to be raised, and, after a timed delay, the channel (46) to be lifted for ejection of a billet.

Abstract: 1378062 IGFETs SUWA SEIKOSHA KK 31 Oct 1972 [15 Nov 1971 16 Nov 1971] 50136/72 Heading H1K In an IGFET comprising diffused source and drain regions the gate insulation is laterally spaced from the edges of these regions and an inversion layer is formed beneath other insulation bridging the gaps so formed. A typical device is formed by vapour depositing alumina (or silica or silicon nitride) over a semi-conductor substrate thereby forming an inversion layer. After forming apertures in the alumina and diffusing through them to form source and drain regions, insulation is deposited overall and apertured over the site of the gate electrode, from which the alumina is removed and replaced by the gate insulation. After forming apertures over the source and drain regions the source, drain, and gate electrodes are provided. Alumina is first deposited as before and removed except where it overlies the source-drain gap by etching through a silica mask. Silica is then deposited overall, and etched to expose the source and drain sites. Doped polycrystalline silicon is next deposited overall and etched so that it remains only on these sites and on strips extending from them. Further silica is deposited and etched to expose parts of the strips and the site for the gate, and the alumina at the site removed by phosphoric acid and replaced by vapour deposited silica. Electrodes are then provided by conventional methods. In a modification a layer of silicon dioxide is provided beneath the alumina and a voltage higher than that used in operation applied to the gate to cause trapping of electrons or holes at the dioxide-alumina interface in order to produce the inversion layer. In another modification the alumina is replaced by superposed layers of polycrystalline silicon and silica. In this case heavy reverse biasing of the source and drain regions causes implantation of electrons or holes in the polycrystalline material by avalanching, thereby producing the inversion layer beneath it.

An arrangement for modulating a squarewave carrier signal, in which the modulating signal and carrier are narrowly separated in frequency, and deriving a single side-band signal from the resultant signals, comprises means for keying the modulating signal at the carrier frequency, means for subtracting from the resultant signal a signal at the carrier frequency and a signal at the modulating frequency, whereby the carrier and modulating signals are cancelled and filter means for removing one of the side-bands. The modulating signal is amplified in amplifier 11 and applied via path 19 to a series circuit including resistor 32, diode 33, collector-emitter path of transistor 34 and resistor 35. A square-wave carrier signal obtained from a free running multivibrator 13 alternately biases diode 33 to its conducting and cut-off conditions, hence a modulated signal is developed across resistor 35. The carrier component of this signal is cancelled by an inverted square-wave signal applied via resistor 64 and lead 17 to the junction of diode 33 and transistor 34 and the modulating signal is cancelled by an inverted signal of half the modulating signal amplitude which is obtained from circuit 15 and applied to the same point in the series circuit. The double side-band signal is connected to the output circuit via a filter circuit 18 which removes the upper side-band.
