Title: Cylindrical roller bearing has hollow rollers - which contain lubricating substance for gradual usage
Inventor: SATO KOZO
IPC: F16C33/34
Filed: 1974-02-06
Abstract: A cylindrical roller bearing has tubular roller elements. Each element carries two tubular sleeves which are free to rotate inside the roller tube. The overall length of the two sleeves is fractionally larger than the roller, thus acting as spacer for the roller cage. The sleeves are filled with a lubricating substance which reaches the bearing races through the gap between the two sleeves and a hole in the roller tube at a matching axial position.
Patent DE-2407618-A1 (DE)
Title: Pressure limiting valve for alternative pressure lines - equalises both pressure lines when relief valve opens
Inventor: GRAETZ REINHOLD
IPC: F16K17/10
Filed: 1974-02-16
Abstract: The valve body has two annular spaces each communicating with a separate pressure source and with two non-return valves respectively. The higher of the pressures in the annular spaces causes the appropriate non-return valve to open to allow fluid to flow through two apertures to the space below the piston which slides in a sleeve. The fluid also flows through an orifice and the apertures to the valve which is opened if the pressure is greater than the pre-set value. When the valve opens the pressure in the space drops because of the restriction of the orifice. This causes the piston to rise allowing one annulus to communicate with another annulus.
Patent DE-2412982-A1 (DE)
Title: Carburizing and core hardening of steels - using a continuous belt furnace supplied with pressurized gas
Inventor: KIEFERLE WOLFGANG
IPC: C21D1/74
Filed: 1974-03-18
Abstract: A process is claimed whereby steels may be carburised and quenched to give surface and/or core hardening in a single appts. The work is placed on a continuous belt which passes first through a furnace. Purified air and gas (pref. propane) are heated by heating coils to 1120-1140 degrees C and passed under pressure through ducts to emerge through several orifices very close to the work. The work is therefore subjected to high carbon potentials giving efficient carburization. The belt then carries the work into a cooling zone, up to twice as long as the furnace, which is also filled with furnace gas. This cools the work under controlled conditions to give surface and/or core hardening. It then needs no further heat treatment. Steels can be treated cheaply and continuously in one appts. Higher surface hardnesses can be obtd. than with conventional processes.
Patent DE-2416301-A1 (DE)
Title: Conversion of calcium chloride to potassium chloride - in scrubbing liquor from air purifying plant by ion exchange, for fertilisers
Inventor: HOELTER HEINZ
IPC: B01D47/00
Filed: 1974-04-04
Abstract: Process for converting CaCl2 accuring in the water circulation of wet scrubbers in air purifying plants, as in parent patent, in which the scrubbing water is pumped over an anion exchanger, which can be regenerated with NaOH soln. so that NaCl forms and the Ca ions are retained in the scrubbing process, is extended by the use of KOH soln. instead of NaOH soln. for regeneration. The KCl formed is ecologically harmless and can be used as fertiliser, giving considerable economic advantages over the conventional process. Regeneration also results in a considerable saving in the amt of lime added.

Abstract: The bag-type container is of flexible material and has a cutting mechanism mounted inside it, with a base portion for holding in one hand, and on which a cutting portion held in the other hand pivots. Both portions have cutting edges, so that rotation in relation to each other cuts the container open. The two can be attached together by a link extending downwards from the base and to the opposite edge, each having straight edges near each other so as to determine a tear-open line. The container can be of plastic, folded and sealed in the transverse direction. The opening mechanism can have a sharp-edged feathered flange with a number of openings into which the securing plastic is poured.
Patent DE-2426717-A1 (DE)
Title: Metal casting moulding box - with perforated tube in lower moulding box for air exhaustion from mould cavity
Inventor: GOODWIN JOHN
IPC: B22D18/06
Filed: 1974-06-01
Abstract: A metal casting is produced in a mould from which the air is exhausted during the casting operation so that a vacuum is maintained in the mould cavity. Several regions of differing vacuum can be established to vary the casting pressure acting on the vacuum regions. Air present in the mould can exert a back pressure and reduce the casting pressure. The air can give rise to shrinkage cavitites, both can be avoided by the new process.

Title: Pivoting closure for powder-contg. drum esp. for dyes - has axis offset from plane of lid to give long life seal
Inventor: KUENY WERNER
IPC: B65D90/62
Filed: 1974-11-22
Abstract: A closure unit for use on the mouth of a container or drum for pulverulent matl., wsp dyestuffs, clouring matter etc., consists of a flange-like collar for detachably mounting on the vessel and a pivoting lid which closes the internal space of the collar. The pivoting axis of this lid intersects the longitudinal axis of the opening at right angles, and does not pass through the rim of th elid but is pref. outside it (i.e., away from the vessel). The sealing surface of the collar, against which the rim fits when the lid is closed, is a spherical zone having its centre of curvature at the intersection of the pivoting axis and the longitudinal axis. The plane of the lid, when closed, is pref. parallel to the pivoting axis. The surface is pref. of metal, and the rim is formed of a sealing ring of plastics, esp. ethylenepropyl, set in a groove between the edges of the two plates constituting the lid. The vessel is inverted, before the lid is pivoted through 90 degrees about the pivoting axis to discharge the contents. The closure withstands long periods in service, without either jamming or leaking. The rim is not influenced by the presence of the pivoting axis.

Title: Fast battery charger for electric vehicles - has intermediate battery charge off-peak to reduce loading on AC supply network
IPC: H02J7/00
Filed: 1974-12-07
Abstract: The fast battery charger, for electric vehicles, has the a.c. network coupled via a bridge rectifier (3) to an intermediate battery (5) that is used in conjunction with the rectifier output to charge the discharged battery (1) connected to external terminals (4). Interconnected switches allow the intermediate battery to be charged from the rectifier on its own. The advantage of the intermediate battery lies in its reducing the loading on the a.c. supply network when a load battery is rapidly charged.

Title: Rotor-kite type flying machine - has two S-shaped lifting surfaces set at right angles, balancing lift characteristics
Inventor: LANGE GUENTHER DR ING
IPC: B64C31/06
Filed: 1975-04-03
Abstract: The flying machine, tethered by a string/wire, comprises two S-shaped lifting surfaces, free to rotate around a common axis but linked to one another in such a way that their planes near that axis are at 90 deg., ensuring a good balance between lift- and drag-forces throughout the rotation cycle. A central circular disc separates the surfacesends, all three being perpendicular to the axis. Strength and aerodynamic stability is increased if the ends of the S's near the discs, are curved more strongly than the middle portions. Structural strengthening can be embodied but consequential adverse effects must be watched.

Title: Marine riser for floating oil or gas platform - with pipe sections linked by ball joints and tensioning ropes
Inventor: BRANIG GERHARD DIPL ING
IPC: E21B17/08
Filed: 1975-04-24
Abstract: A marine riser for offshore wells in great depths of water consists of a number of sections (riser joints) which are linked to each other by ball joints. Tensioner ropes keep the whole riser under tension. The ball joints are designed for a minimum of friction at max. tensile stress. This eliminates bending and transverse stresses which lead to premature breakdowns of conventional marine risers. The system needs to absorb merely tensile forces in addition to the hydrostatic forces.
