Title: Band saw for dividing animal carcasses
Inventor: ELMER STEFAN
IPC: A22B5/20
Filed: 1984-04-06
Granted: 1989-08-24
Abstract: A band saw wherein one of the pulleys for an endless band-like blade is movable toward and away from the other pulley to relax the tension upon or to tension the blade. The one pulley is permanently biased away from the other pulley by a relatively weak spring whose bias can be overcome by hand to facilitate the removal of a blade or the application of a fresh blade. In addition, the one pulley is normally biased away from the other pulley with a pronounced force by a package of dished springs whose bias upon the one pulley can be interrupted by a single-acting cylinder and piston unit whose piston is installed between the dished springs and a reciprocable carriage for the one pulley. The dished springs react against a support for the pulleys and bear against the piston. Two twisting units are provided to maintain a central portion of one of the two elongated reaches of the blade in a plane which is normal to the axes of the pulleys, and such twisting units can be pivoted or otherwise moved into and from engagement with the one reach by fluid-operated motors.

Title: Membrane oxygenator
Inventor: DIETTRICH LAMBERT JOHN
IPC: A61M1/22
Filed: 1984-03-06
Granted: 1989-11-09
Abstract: A novel device for mass transfer across a membrane is disclosed, which is particularly suitable for use as a blood oxygenator. The novel device is of the type having a pleated, selectively permeable membrane defining first and second sets of alternating pockets for the flow of a fluid to be treated (e.g. blood) and a treating fluid (e.g. oxygen), and a discrete support screen disposed within each of the pockets of said first and second sets. Of considerable importance is the feature that the support screens are designed to be substantially interdigitated when the assembly of membrane and support screens is held as a compressed stack within the housing of the device. The novel mass transfer apparatus may be utilized as a compact blood oxygenator with excellent gas transfer rates, low pressure drops and negligible trauma to blood components.

Title: Anaerobic purification equipment for waste water
Inventor: VELLINGA SJOERD HUBERTUS JOZEF
IPC: C02F3/28
Filed: 1985-07-18
Granted: 1987-12-23
Abstract: A considerable portion of the gas developed by fermentation in an anaerobic purification equipment for waste water, together with buoyant sludge, is collected by at least one additional collecting system (5), before it may reach the upper part of the reactor. This additional collecting system is fitted at a distance below the collecting system (6) fitted as usual just below the level of one or more overflow gutters (3; 23) for purified water. The additional collecting system (5) has a hydraulic link with one or more rising pipes (7, 7', 27, 32,31) for raising the liquid sludge mixture by gas lift action. The rising pipes discharge into a separation device (8) from which one or more downpipes (9; 29) for returning separated liquid and sludge extend to the lower section of the reactor chamber. As a result of the tranquility at the top and the turbulence near the bottom, a substantial increase of the load capacity of the equipment can be obtained.

Title: Hosiery toe closing method and apparatus
Inventor: HODGES MICHAEL JOHN
IPC: D05B23/00
Filed: 1985-08-23
Granted: 1989-01-26
Abstract: Toe closing socks first involves stretching them flat on a carrier, then one of the resulting confronting layers of fabric is effectively held substantially immobile by a fabric-holding device and the other layer is displaced longitudinally relative thereto by a movable displacing means brought into engagement therewith. Maintaining the layers mutually displaced, for example by clamping them to one another, they are conveyed past a sewing machine and seamed. By seaming the layers together while they are mutually displaced, the seam will adopt an overfoot or underfoot position in the finished sock due to readjustment of the fabric and the return of the layers to their normal relaxed relative dispositions.

Inventor: BRINER EMIL
IPC: D01H4/52
Filed: 1986-09-11
Granted: 1989-06-08
Abstract: In order to start or recommence spinning of a yarn in a friction spinning device, the following method steps are carried out upon start-up of a new spinning operation or upon piecing after a thread break: fibers separated by an opening device are delivered by means of a fiber transporting passage to a rotating friction spinning drum and are twisted to form a twisted fiber structure; when the twisted fiber structure has substantially reached a predeterminate diameter or size, then the twisted fiber structure is transported by an airstream delivered by a pressure duct towards and into a guide tube and is forwarded therein into a convergent space of rotating withdrawal rolls; and the twisted fiber structure is caught at production speed by these withdrawal rolls and delivered on a divergent side of the withdrawal rolls to a receiving suction device which transfers the spun yarn subsequent to the twisted fiber structure to further processing elements.

Abstract: Superior tolerance to catalyst coking in a process for production of aromatics from C₂ to C₅ hydrocarbons is obtained with a catalytic composite comprising a gallium component and a crystalline aluminosilicate zeolite incor­porated into a phosphorus-containing alumina matrix. A five-fold reduction in the coke content of the spent catalyst of the instant invention is observed which is directly attributable to the phosphorus-containing alumina matrix. A novel method of preparing this catalyst is presented, along with a novel process for the dehydrocyclo­dimerization of C₂-C₅ aliphatic hydrocarbons using this catalyst system.

Abstract: A small lightweight auxiliary power plant including an engine, electrical alternator, water pump, air conditioning compressor and a heat exchanger is mounted at a convenient location on the tractor of a truck or other large vehicle. The main engine of the truck operates the existing truck air conditioning and heating system in a normal manner when the main engine is running. When the main engine of the truck is not operating and the smaller engine of the auxiliary power plant is operating, the truck air conditioning and heating system is operated by the auxiliary power plant. The heat exchanger of the auxiliary power plant then utilizes the heat of exhaust gases generated by the auxiliary power plant engine to warm the truck engine during the time it is not operating so that easy starting of the truck engine is made possible even in very cold regions. The electrical alternator of the auxiliary power plant supplies electrical power for the truck electrical system when the truck engine is not running. The truck storage batteries serve the electrical systems of the truck and the auxiliary power plant. The auxiliary power plant serves as an emergency back-up system if the truck alternator or compressor should fail. The arrangement reduces air pollution caused by operation of the truck engine for long periods of time while the truck is stopped. Provision can be made for warming the fuel tanks and fuel lines to prevent fuel gelling in cold climates.
