Title: Hair treatment method and device
IPC: A45D20/10
Filed: 1976-03-08
Abstract: 1534056 Hair styling SPERRY RAND CORP 8 March 1976 [4 June 1975] 09193/76 Headings A4V and A5R [Also in Division F1] Hair is treated by projecting onto it an air stream in the form of a pulsating air current by establishing an air stream in a conduit having a discharge outlet, and periodically varying the magnitude of the air stream flow rate at the outlet to provide the pulsating air current. As shown, a hair treating device 10 e.g. a heated air douche comprises a fan 26 driving air over a heater 30 to an outlet 14, a variable flow impedance 34 in the form of a flexible plastic sheet being mounted in the outlet so that it may pivot at one of its ends 56 about a horizontal or (as shown) vertical axis (35). Air turbulence in the conduit 20 of the device is said to cause the sheet 34 to periodically pivot and flex (Figure 3, not shown) giving the discharged air pulsating characteristics. The sheet 34 may have polycarbonate strips 60, (62) at its outer end to provide weight and a foam rubber or plastics edging strip (77). The device 10 has a control button 32 providing for cold, warm, or hot (at a higher fan speed) air, the pulsating air current being said to avoid any compacting of the hair being treated. The outlet 14 containing the flow impedance may be removed (Figure 1, not shown) so that the device provides a steady air flow or alternatively (Figures 10, 11, not shown) a button (80) may be pressed to lock the impedance.

Title: Process for reducing the extensibility of nylon cords and the like
IPC: D06M11/05
Filed: 1948-04-02
Abstract: Cold-drawn thread, cord or other filamentary material made of nylon is subjected while stretched to treatment with an aqueous fluid at a temperature of at least 100 DEG  C., whereby its extensibility is reduced.  Conveniently the treatment may be combined with the curing of a precondensate of a thermosetting resin with which the nylon may be impregnated.  The stretching load should be 30-50 per cent of the breaking load.  In one form of the invention the nylon is immersed in boiling water for 20-30 minutes until it is set.  The water may contain 5-10 per cent of a swelling agent such as formic acid, phenol or sodium sulphate.  Preferably, however, the nylon is treated with steam at 120-160 DEG  C. and at a pressure of 40-50 lbs. per sq. inch.  In this form of the invention, impregnation with the solution of resin-forming materials can be carried out before the heat treatment without danger of washing out and the subsequent heating can be long enough to set the nylon and cure the resin.  The nylon may be wound under tension on a package or bobbin and in this case it may be subjected to a short preliminary treatment with saturated steam at 100 DEG  C. to facilitate the stretching operation. The resin may be urea-, phenol- or resorcinol-formaldehyde.  In an example a nylon cord is drawn through a bath of 6 per cent aqueous resorcinol-formaldehyde, then through a tube containing saturated steam at 100 DEG  C. and wound on a bobbin under tension.  The tensioned cord is then treated in an autoclave under 45 lbs. pressure at 150 DEG  C. for 20 minutes and conditioned in an atmosphere of 65 per cent relative humidity at 70 DEG  F. Specification 616,549 is referred to.

Abstract: 590,300. Centrifugal compressors. BRITISH THOMSON-HOUSTON CO., Ltd. April 17, 1945, No. 9634. Convention date, April 21, 1944. [Class 110 (i)] [Also in Group XXIX] A centrifugal supercharging compressor has a vaned diffuser and the inlet ends of the vanes are angularly adjustable. The adjustment is effected through a control device responsive to the ratio of the static pressure rises in the impeller and the diffuser respectively and operates to maintain that ratio constant. In the example the desired ratio is unity. Bellows 21, 22 are subjected respectively to the impeller inlet pressure and the pressure between the impeller and diffuser. Bellows 23, 24 are subjected respectively to the last mentioned pressure and the pressure at the outlet of the diffuser. The equal armed lever 19 moves from its mid position when the pressure rise in the impeller differs from that in the diffuser. Such movement operates a piston valve 30 controlling the admission of pressure fluid to a cylinder 29 and movement of the piston 33, acting through a lever 17, adjusts the angular position of the inner parts 16 of the diffuser vanes in a way to bring the ratio of the pressure rises back to unity. Specification 590,301 is referred to.

Filed: 1945-04-19
Abstract: 596,326. Deforming corundum or spinel. LINDE AIR PRODUCTS CO. April 19, 1945, Nos. 9780 and 9781. Convention dates, May 17, 1944, and May 23, 1944. Drawings to Specification. [Class 124] In a method of hot forming a unicrystalline rod of corundum or spinel wherein the angle between the longitudinal axis and the C-axis lies between 10 and 75 degrees, a portion of the body is heated to plasticity and deformed by applying force to that portion. It is preferred to bend a rod in the plane defined by the longitudinal axis and the C-axis and the angle between these axes may be in the range 30 to 75 degrees. In stretching the rod to form a portion of reduced cross-section, the angle between the axes may be between 20 and 60 degrees and the process of heating and stretching may be continued until a fine filament is produced. These filaments may be spun or matted to produce a filter pad. Stretching the rod produces a flat ribbon-shaped filament, which on further heating reverts to a circular cross-section. The rod may be twisted preferably when the angle between the axes is in the range 40 to 70 degrees. Heating the rod after deformation produces a glossy scratchfree surface especially suitable when the rod is formed into a thread guide. The Specification as open to inspection under Sect. 91 comprises also an undeformed rod having a smooth or wavy heat-glossed surface and a short section of rod having a V-shaped cut in it which may be heat glossed. This subject-matter does not appear in the Specification as accepted.
