...that power steering was invented by independent inventor Francis W. Davis? As chief engineer in the 1920s of the truck division of the Pierce Arrow Motor Car Company, he saw how hard it was to steer heavy vehicles. So that he would be able to keep the profits from his future invention, Davis left his job, rented a small engineering shop in Waltham, Mass., and developed a hydraulic power steering system that led to power steering.

| 3989535 | Solution of poly(N-acetyl-D-glucosamine) Poly(N-acetyl-D-glucosamine) is soluble in hexafluoroisopropyl alcohol and hexafluoracetone sesquihydrate. The solutions formed may be wet or dry spun into filaments, or cast into films or solid articles, which may be used as absorbable surgical sutures, ... | 11/02/1976 |
| 3988411 | Spinning and shaping poly-(N-acetyl-D-glucosamine) Poly(N-acetyl-D-glucosamine) is soluble in hexafluoroisopropyl alcohol and hexafluoracetone sesquihydrate. The solutions formed may be wet or dry spun into filaments, or cast into films or solid articles, which may be used as absorbable surgical sutures, ... | 10/26/1976 |
| 3982543 | Reducing capillarity of polyglycolic acid sutures Useful surgical elements consist of a sterile synthetic copolymer containing, by mole percent, about 15 to 85 percent glycolic acid and 85 to 15 percent lactic acid, which has enhanced tissue absorption as compared with polylactic acid and enhanced solubi... | 09/28/1976 |
| 3968051 | Freeze drying photochromic filters A fast-acting photochromic filter--i.e. a filter whose optical density in the visible light range of 4000 to 7500 angstroms is increased when subject to radiation shorter than 6000 angstroms--which is room temperature stable, that is from at least about 2... | 07/06/1976 |
| 3961629 | Using hydrophilic polyurethane laparotomy sponges A surgical laparotomy pad having uniquely useful properties comprises a hydrophilic polyurethane sponge in which the sponge pores have a surfactant coating to accelerate absorption of body fluids into the pores at medically desirable rates, the fluids bei... | 06/08/1976 |
| 3960152 | Surgical sutures of unsymmetrically substituted 1,4-dioxane-2,5-diones Unsymmetrically 3,6-substituted 1,4-dioxane-2,5-diones may be polymerized to give living-tissue absorbable, hydrolytically degradable surgically useful polymers. These polymers have predominantly regular rather than random spacings of side chains, may be ... | 06/01/1976 |
| 3959947 | Winding suture reel-labels Surgical sutures are wound from a needled end on a printed reel-label. The reel-label is made from sealed together thicknesses of stiff inert sterilizable label stock, with an aperture which acts as a rotable axis to permit holding between a finger and th... | 06/01/1976 |
| 3956330 | N,N-diethyl-4-methyl-1-pi-perazinecarboxamide pamoate Asthma is effectively treated by inhalation of powder dispensed from an aerosol suspension of powdered N,N-diethyl-4-methyl-1-piperazinecarboxamide pamoate, which is dispersed as a fine powder, essentially below 10 microns in particle size, which giv... | 05/11/1976 |
