Title: Illuminated and modular soft tissue retractor
Inventor: VAYSER ALEX
IPC: B22D29/00
Filed: 2012-09-21
Abstract: A surgical instrument for illuminating a surgical field is presented. The surgical instrument comprises a handle having a proximal portion, a distal portion, and a longitudinal axis; a retractor blade releasably coupled to the handle, the retractor blade having a first surface and a second surface, wherein the second surface is configured to engage and retract tissue and the first surface faces away from the second surface; and an illumination element coupled to the handle.

Abstract: The present invention provides a filter cartridge for a vacuum cleaner. The filter cartridge comprises first and second opposite end walls, a side wall or walls which extend between the end walls so as to define an enclosure which surrounds a filter interior. One or more of the walls comprises filter membrane material. The cartridge has an opening provided through the first end wall for receiving air-entrained detritus into the interior, the opening being defined by a rigid support structure which spans and supports the first end wall of the cartridge. The rigid support structure of the first end wall comprises a central inner collar which defines the filter cartridge opening. A non-return valve is provided in the filter opening, which non-return valve is provided with resilient constraint means which is adapted to adopt an open configuration in response to a threshold reduced pressure in the cartridge interior, and which closes, or substantially closes, when the pressure reverts to ambient. The non-return valve comprises a flap of material which can deflect between a closed position in which the flap blocks the filter opening and an open position in which the flap is deflected away from the open position and into the filter interior. A shroud is provided around the filter opening, projecting inwardly into the filter interior from the collar which defines the opening. The filter cartridge may be collapsible to permit storage before use in a generally flat configuration.

Abstract: A fluid fuel burner system (10) for minimum production of NOX under varying rates of fuel firing and varying rates of combustion air or oxidant supply, which comprises a fuel burner (12) including means (14, 16) for burning liquid and gaseous fuels respectively. Liquid fuels are burned in an axial burner tube (48) and the gaseous fuels are burned in a plurality of gas burner tubes (42) located in a circle coaxial with the liquid burner. A first air or oxidant plenum (20) supplies primary-plus-secondary air (66) or oxidant, the primary air (52) or oxidant going to the liquid burner (94) and the secondary air (63) or oxidant going to the gas burner (44). The total of primary plus secondary is less than stoichiometric flow so that the combustion of the fuel in a first combustion chamber (80) provides a reducing atmosphere to preclude the formation of NOX. Means (60) are provided for independently controlling the primary air or oxidant flow compared to the secondary air or oxidant flow, or vice versa. A second air or oxidant plenum (24) provides tertiary air (68) or oxidant to a second combustion space (82) downstream of the first combustion chamber (84). Control means (30) provide independent control of the primary-plus-seconday air (66) or oxidant flow to the first plenum (20) as a selected ratio to the tertiary air (68) or oxidant, that flows to the second plenum (24).

Abstract: In a known method of reactive sputtering wherein inert gas and reactive gas are introduced into a reaction chamber (1) provided with a pair of oppositely arranged electrodes (3,6) on one of which is placed a semiconductor substrate (4) to be treated and a target material (7) on the other electrode. An RF power (11) is applied to the latter electrode (6) to generate plasma which activates the inert gas to eject silicon particles from the target material (7) for reaction with nitrogen radical for forming a film of silicon nitride on the substrate (4). The invention improves the quality of said film as well as its growth rate by activating reactive gas in advance before introducing the same into the reaction chamber (1). A microwave oscillator (18) is used for activating the reactive gas, and the electrode (6) on which the target material (7) is placed comprises a magnetron.

Abstract: The present invention relates to a device (10) for regulating the temperature inside refrigerators with at least two compartments, one for frozen (1) and the other for fresh food (2), each with its own evaporator (4,5) in a single series refrigeration circuit. Besides an ordinary thermostat (11), the regulator (10) also consists of a thermistor (13) inside the fresh food compartment where the air temperature is lowest. When the compressor (6) on the refrigeration circuit is operated for a long time, e.g. when large amounts of unfrozen food are placed inside the freezer, to prevent the fresh food compartment from falling below 0°C, the thermistor (13), which forms part of a bridge circuit at the input of a voltage comparator, switches the output of the said comparator which acts on the main thermostat (11) circuit to stop the compressor (6). This enables maximum use to be made of the refrigerating capacity of the system with no danger of freezing the food in the fresh food compartment.

Abstract: In the process of scrubbing flue gas to remove pollutants therefrom by contacting the flue gas (1) with an aqueous reactant mixture (11) of water and pollutant absorbent, water soluble chloride impurities present in the flue gas (1) and make-up water (40) tend to build-up as the supernatant liquor (21) from the spent reactant mixture (13) dewatering cycle is recycled for mixing with unreacted pollutant absorbent (30) to form additional reactant mixture for contacting with the pollutant laden gas. The build-up of chlorides in the reactant mixture is controlled by passing a purge stream (23) of the choride containing liquor (21) in contact with a hot drying gas (1, 9) so as to evaporate the water and crystallize the chloride impurities in the purge stream. The crystallized particles of chloride salt are then removed from the drying gas as a dry solid (50, 52).
