The instrument further comprises a handle, with optional pocket clip, which is attached to the blade at an offset angle to facilitate manipulation of the blade from a position that leaves the field substantially clear for the simultaneous use of other instruments, such as an opthalmoscope.

Abstract: One version of a fire resistant cigarette comprises a charge of tobacco in a low-porosity wrapper substantially free of burn accelerator. The sidestream smoke from this cigarette can be reduced by treating the wrapper with water or ethyl alcohol. Fire resistance is further improved by depositing a linear burn rate reducing substance on the paper from the group consisting of citric acid, magnesium citrate, magnesium acetate, tartaric acid, acetic acid, lactic acid, a sugar, non-fat milk and skim milk. Similar results are achieved with conventional medium to high porosity cigarette papers by treating them with a burn rate reducing substance from the same group. In the case of high porosity cigarette paper, if only a part of the surface area is treated, the porosity of the untreated areas controls tar, nicotine, and carbon monoxide delivery.

Abstract: An improved tobacco smoke filter is characterized by an undiluted air passage formed between a smoke-impervious plug wrap and an air-impervious tipping wrap by loosely wrapping the tipping wrap about the plug wrap along a section of the filter extending from its smoke discharge end. In a preferred embodiment, the loose wrapping is effected by reducing the cross-sectional perimeter of the rod and plug wrap along the aforesaid section while keeping the tip of the cross-sectional perimeter substantially constant throughout its length. A raised lip is provided at the smoke discharging end of the rod and plug wrap to define a cigarette holder in the filter. For circumstances where the cross-section of the filter plug becomes too complex for adherence of the tipping paper, heat shrinkable film can be laminated in the tipping paper so that after the entire cigarette is assembled, it can be subjected to heat and cause the tipping paper to shrink to the appropriate size.
