Title: Heat bonding process
Inventor: GRIFFIN GERALD JOSEPH LOUIS
IPC: B31B50/64
Filed: 1963-07-04
Abstract: 1,003,100. Seaming non - metallic sheet material. H. F. GATWARD. July 3, 1964 [July 4, 1963], No. 26563/63. Heading B5K. A thermoplastic material 8 is heat bonded to a cellulosic material 7 by applying heat directly to the cellulosic material and indirectly to the thermoplastic material via the cellulosic material to melt the surface of the thermoplastic material adjacent the cellulosic to a sufficient degree to obtain a stick, the heat conducted into the remainder of the heated part of the thermoplastic material being allowed to escape quickly into an adjacent heat sink 5 before damage or distortion of the thermoplastic material occurs. Apparatus for effecting the bonding comprises a tool 6 heated by electrical resistance heating by a coil 10 to a temperature, e.g. approximately 195 C., above the softening temperature of the thermoplastic material 8 but below that likely to damage the cellulosic structure of the material 7. A second tool 5 is eooled, preferably by a water jacket 9, and acts as the heat sink, the temperature of the heat sink not substantially exceeding 20 C. Pressure may be applied by a lever system in the direction of the arrow A. Cooling may be effected before removal of the tools by removing heat from the tool 6 and circulating cooling fluid in channels therein. The process may be used to bond a thermoplastic handle 1 to a paper carrier bag 3 or to paper a patch 4, Fig. 3 (not shown). The handle 1 may be moulded and be attached to the bag 3 by flat disc-like extremities 2 or, alternatively, may be of ribbon form, Fig. 3 (not shown).

Abstract: 918,867. Stud and socket fastenings; clamps. GARRETT CORPORATION. July 29, 1960 [July 30, 1959], No. 26564/60. Class 44. [Also in Group XXVII] Coupling means for securing a mounting flange of an accessory to a co-operating flange of a support includes bayonet type connecting means for temporarily connecting the accessory to tho support, a latch arranged to prevent relative rotation between the flanges from the engaged position, and clamping means for permanently securing the flanges together and also holding the latch in its engaged position and for moving it thereto. As shown, a flange 11 on an accessory 12 is provided with a pin 15 which is engageable in an opening 16 in a flange 10 secured to a support pad on an engine. A recess 17 on the flange 10 provides a shoulder 18 which is engageable with a rearwardly-facing shoulder 20 on the pin 15 when the accessory is partially rotated after the pin has been engaged with the opening 16. A latch member 23 is then engageable with a notch 24 on the flange 11 and is retained by a channel-section clamping-ring 28 which is applied over both flanges. The invention is applicable to the mounting of generators or starters of power plants on support pads of engines.

Title: Liquid clarification
IPC: C02F1/24
Filed: 1949-10-17
Abstract: 659,978. Gravity-separation apparatus. TRIGGS, W. W. (Gibbs, Inc., F. S.). Oct. 17, 1949, No. 26618. [Classes 46 and 111] [Also in Groups VI and XII] Matter suspended in a liquid, such as industrial waste waters, coagulated impurities in raw sugar juice or fats in glycerine, is removed from the liquid by introducing the liquid containing the suspended matter into a zone in which a generally downwardly flowing body of the liquid having an essentially quiescent surface is confined, the point of introduction of the introduced liquid being below the quiescent surface and substantially centrally thereof, passing minute gas bubbles into the downwardly flowing liquid, now including the introduced liquid, at a point below the introduction of the introduced liquid and recovering the suspended matter floated to the surface of the liquid by attachment of the bubbles thereto. As shown, the suspension is introduced through a pipe 17, (see Fig. 1), to flow upwards through a riser pipe 16 to a distributor 18 of inverted cone shape to spread the liquid radially and prevent disturbance of the surface of the body of liquid forming the quiescent zone in the upper part of tank 10. The liquid flows downwards and under the bottom edge of an annular baffle 14 and upwards through the space between the baffle 14 and the tank wall 11 to overflow into trough 37. The edge of the tank wall 11 is provided with an adjustable weir 39. Liquid is continuously drawn from the bottom of the chamber through a header member comprising apertured rings 28 and charged with air or other gas (see Groups VI and XII) and the gas-charged liquid is returned into the header comprising apertured rings 27. The floating matter is removed from the quiescent surface by two flexible skimmer blades 23, e.g. of rubber, rotated by motor 20, the blades sweeping the surfaced sludge over a radially extending riser plate 40 into a collection trough 24 which discharges through pipe 25. The lower edges of blades 23 lie below the leading edge 57 (see Fig. 4) of the plate 40, the leading and trailing edges of which are radial with respect to the centre of rotation of the blades 23, but the discharge edge 59 of trough 24 is parallel to the trailing edge 58 of the plate 40 and, like the edge 58, the edge 59 stands above liquid level. In a modification the lower header 28 is omitted, the liquid to be charged with gas bubbles being drawn from a suction box depending from the trough 37, then charged with the gas and returned to a header 27.

Title: Process for growing crystals
IPC: H01L21/00
Filed: 1960-08-02
Abstract: In pulling a dendritic crystal from a supercooled melt using a seed crystal oriented as shown in Fig. 3, the melt is prepared at or just above its melting point, the seed is fed into the melt, before, during or after supercooling, to a depth of at least 1 mm., and is then pulled from the supercooled melt to form a single extension thereof.  The melt may be super-cooled by <PICT:0911359/III/1> <PICT:0911359/III/2> p  5 DEG -40 DEG C.  After the seed has contacted the melt, the melt may be supercooled by 5 DEG -20 DEG C., the seed may be fed into the melt during or after supercooling to a depth of 2,5-25 cm., and then withdrawn at a rate of 5-25 cm./min. The melt may contain a doping agent (see Specification 894,241).  The crystal pulled may be of silicon, germanium, indium antimonide, or gallium arsenide. In the latter case, the crystal may be pulled in an atmosphere of arsenic.  Pulling may be effected in an atmosphere of one or more of argon, helium, hydrogen, or nitrogen, or in a vacuum. The pulled crystal may have a thickness of 0,025-0,63 mm. and a width of 0,5-5 mm.  As shown in Fig. 2, a crystal 34 is pulled from a melt 26 in an inductively heated crucible 24 through an aperture in a lid 30.  Specification 889,058 also is referred to.

Abstract: 458,382. Television. SCOPHONY, Ltd., BAYNES, J. D., and WIKKENHAUSER, G., Thornwood Lodge, Campden Hill, Kensington, London. Sept. 27, 1935, No. 26800. [Class 40 (iii)] When the scene being transmitted is changed, the bright parts of the old scene tend to persist on the fluorescent screen of the receiving cathode-ray tube, due to after-glow, and so interfere with the new scene. This is prevented by reducing the intensity of illumination of the received picture. When a kinema film is being transmitted, 12 frames occurring at the change of scene are rendered opaque. When direct transmission of objects takes place, a shutter or filter may be used to reduce the light falling on the photo-electric cell.
