Title: Composite bending tool for automatic stamping machines
IPC: B21F1/00
Filed: 1970-03-10
Abstract: Bending or deforming tool for automatic bending and stamping machines is constructed such that the various tool elements can be introduced into it on slides, to which they are attached by a claw and from which they can be easily lifted off. Guide-in sliding channels are provided in each of the most frequently used working directions for the slides with the tool elements. All these paths end in the central rectangular section where the base of a tool holder is located to which the various component elements are bolted on. The system thus provides a basic permanently fitted tooling fixture to which only working heads need fixing, these being made up from composite tooling elements which are slid in and need only to be bolted to the tool holder incorporated in the tool.

Title: Stocking rows - to give separation without machine stoppage - and allowing close location of oscillating components
IPC: D04B15/00
Filed: 1970-05-16
Abstract: To develop the separation rows in stocking manufacture using a double cylinder circular knitter, the yarn is drawn into all needles in the lower cylinder before being passed to alternater needles in the upper cylinder. Loops are then passed up to the remaining needles for the first row to be completed, before future rows are knitted in the lower cylinder. This allows the separation rows to be achieved without stopping the machine, and for the oscillating components to be located close to each other, and reducing the distance of any oscillating swing.

Title: Urea process from ammonia and carbon dioxide - improved by stripping recycle carbamate with feed carbon dioxide
IPC: C07C273/04
Filed: 1971-06-08
Abstract: In a high pressure synthetic of urea, aq. NH4 carbamate (I) is recycled by pressurising and stripping with feed CO2, pref. at about synthesis reactor pressure. This is carried out in a heat exchanger, externally heated to decompose (I), giving a high pressure off-gas contg. CO2 and NH3 and a discardable liquid effluent. Feed NH3 is pref. added to the off-gas to give an NH3:CO2 ratio of 2:1 and this is passed through a heat-exchanger to heat effluent from the reactor, thus decomposing (I) in the effluent and giving an off-gas which is converted to the aq. (I) soln. This results in the condensation of molten (I), to produced a gas-liquid mixture of low water content. This condensed (I) is passed to the synthesis reactor. Alternatively, the enriched off-gas is cooled in heat-exchange with liq. water to produce steam used to heat the synthesis effluent and decompose (I). Advantages are avoidance of urea decomposition by stripping operations, reduced water content of recycled (I), conversion rate raised from 67-75%, reduction in reactor vol.% a 25% reduction in energy required for evaporation.

Title: Low carbon high chromium steel prodn. - by addn. of chrome ore and manganese to give a solid slag
Inventor: BOROWSKI KURT DIPL-ING
IPC: C21C5/00
Filed: 1973-08-16
Abstract: Addition to 2,100,115 relating to a high Cr steel from an O converter process with low Cr slagging and max. decarburizing rate. The steel is refined by adding the chrome ore and/or magnesite in the form of fine particles, average grain size being 3 mm and by means of compressed air. The amt. added depends on the initial Si content of the high C ferrochrome melt. The addns. of chrom ore and/or magnesite are increased with increasing Si content to prevent the formation of a liquid slag. The quantities are chosen so that the m.p. of the non-metallic constituents in the converter lies above 1950 degrees C, and the constituents are held at a temp. below their m.p. The final C content of the refined steel melt is kept within plus-or-minus 0.3%, Cr losses being avoided.

Title: Interlocking seam for joining sheet metal parts - PARTS ARE DOVETAILED TOGETHER AND SECURED BY MECHANICAL PRESSING
Inventor: CARROLL WILLIAM MICHAEL
IPC: F16B5/07
Filed: 1973-10-20
Abstract: Edges of two pieces of sheet metal are joined together by forming a number of radiused dovetails in one sheet which engage with a number of corresp. shaped recesses in the other sheet. After engaging the two edges mechanical pressure is applied to areas, one formed in each dovetail, so that a radially outward flow of matl. is achieved thereby mechanically locking each dovetail in its corresp. recess. Process can be used to form tube from sheet metal by a stamp which forms the dovetails in sheet, drawn from a roll of sheet metal and which subsequently forms the sheet into tube around a mandrel.

Title: Trailing arm suspension for automobiles - has single trailing arm and side mounted compression spring on driven wheel
Inventor: WILFERT KARL DR
IPC: B60G3/22
Filed: 1973-10-30
Abstract: A trailing arm of triangular construction, attached at the vehicle end by two points some distance from another, supports the wheel carrier by two arms. The carrier is attached to the top arm by a pivot pin which allows the wheel carrier to swing in a vertical plane. The lower arm is formed to a U-shape into which the lower end of the wheel carrier enters and is cushioned on either side against the arms of the U by springs. A simple construction is thus achieved using only one trailing arm. It is possible to use the same arrangement with the wheel carrier pivoted in the lower position with the sprung elements in the upper arm.

Title: Ion exchange resin particles sepn. - into cation and anion types using liquid column
IPC: B03B5/62
Filed: 1973-01-23
Abstract: The system uses a liquid column into the top of which the mixed resin particles are fed. The cation and anion exchange resins fall through the liquid at different speed, thus forming separate fractions which are individually collected. The separation is aided by application of laminar upwards flow of liquid in the column and by maintaining air bubbles in the separation zone. Resin particles are made to adhere to the bubbles by a hydrophobic, aerophilic flotation agent. The flotation agent may be selective for the anion exchange resin, e.g. it may be a synthetic anionic polyelectrolyte consisting of polyamines, or for the cation exchange resin, e.g. it may be a synthetic cationic polyelectrolyte consisting of polyacrylamides.

Title: Centrifugal governor with oil pressure responsive control - drop in oil pressure resets governor to avoid damage
Inventor: ZBIKOWSKI GERHARD DIPL ING
IPC: F01M1/24
Filed: 1974-03-09
Abstract: A centrifugal governor has flyweights thrown outwardly, in response to the speed of an engine driven shaft, against the forst of a regulating spring. Outward movement of the flyweights moves a control rod to decrease the fuel supply to the engine thus also reducing the speed of the shaft. Tension of the spring is controlled by a movable piston whose nominal position is controlled by an adjustable spool valve which admits engine oil pressure from a duct to a chamber above the piston. Drop of the engine oil pressure due to bearing deterioration or filter blockage causes a second reference spring loaded piston to throttle a duct and this in conjunction with leakage from chamber resets the governor to a lower speed of engine.
