Patent DE-2504996-A1 (DE)
Title: Prestressed vessel of metallic parts - parts separated by metallic seals of lesser creep strength
Inventor: RIGG SHEPHERD
IPC: F16J12/00
Filed: 1975-02-06
Abstract: The vessel comprises a number of cylindrical parts made of steel and assembled in coaxial edge-to-edge relationship, preferably preloaded radially by a peripheral wrapping of cables. Axial preloading is provided by bolts extending through axial holes in the walls of the cylindrical parts and secured to end members of the vessel. The adjacent edges of the parts are separated by copper seal rings plated onto the edges. After assembly the vessel is heated when the resulting creeping of the copper creates the seal.

Title: Rinsing bottles free of washing agent - using condensate from still base containing agent in which it is reconcentrated
IPC: B08B9/20
Filed: 1975-03-12
Abstract: Process for using off traces of residual washing agent on bottles and crates after their final treatment with such solns. on a bottle washing plant in which aq. condensate is used as rinse liquor. This is distilled from a base to which is returned the rinse liquor and-in which is a soln. of the cleansing agent. Boiling is achieved by coating with hot liquod and operating at reduced pressure. The condensate thus formed is then condensated by contact in a heat exchanger with incoming fresh water for final rinsing and also pretreatment of the bottles. The reduced pressure is obtd. from an ejector operating on one of the liq. circuits. For use on automatic bottle washing plants. The concept of counter current washing operations for (quasi) continuous plants is well established. The system proposed conserves thermal energy while preserving the mass flow advantages of countercurrent wash operation.

Title: Remote control system for machinery in areas exposed to thunderstorms - uses LEDs at transmitter and receiver to indicate shorts and breaks in control line
IPC: H01H9/16
Filed: 1975-04-17
Abstract: The remote control system, for use in areas exposed to the weather -- especially thunderstorms, has its control lines supplied with AC and diodes at the transmit and receive ends. (The remote control device, e.g. a relay, is operated over the receive-end diode). To enable the operator and receiver to see that the control line is not short circuited or broken, these two diodes are of a light emitting type. The LEDs have the advantage in that their electrical characteristics (forward volts etc.) are not so different from those of ordinary diodes and in their responding to very small control currents -- provided there is no short circuit or break.

Title: Mfr. process for moulded gelatine capsule parts - by electrophoretic deposition on stainless steel rods
IPC: A61J3/07
Filed: 1975-06-21
Abstract: Moulded gelatine pieces, partic. containers for the packing of pulverulent or granular medicaments, are manufactured by a process in which stainless steel rods are dipped into a bath contg. an aq. soln of gelatine or an emulsion of such a soln. in an organic liq. An electric current, from the battery, is passed between the rods and the bath and causes a film of gelatine to be deposited by electrophoresis. The rods are removed, the gelatine dried to a water content of 14% and the moulded pieces removed from the rods. Before immersion in the bath the rods are cleaned and may be given a water repellent film. The pieces are of two sizes and for use as a container, one fits into the other. The process is economical, precise and rapid, rejections, when the two halves are fitted together, are reduced.

Title: Hot air hair drying device - has two stage fan directing air through bar shaped casing
IPC: A45D20/10
Filed: 1975-07-04
Abstract: The electric hair dryer has a bar shaped housing (10) containing a two stage electric fan (11) made in one piece on a cylindrical hub. The fan is fitted to the motor (16) so that the motor is held inside the fan hub thus shortening the length of the fan and motor assembly. Air guide walls (10) are fitted between the two stages of the fan to reflect the air from the first fan onto the blades of the second fan. Further guide walls (20) follow the second fan to direct the air to the heater element further down the air canal (12) and also serve to hold the motor in place. Air is drawn into the device through a number of slots (24) in the semi-spherical rear of the casing (10). These allow the air to be drawn in slowly ensuring that hair cannot be sucked into the machine.

Title: Purification of helium - after use in gas-cooled high temperature nuclear reactors
Inventor: TONE HIROHITO
IPC: G21F9/00
Filed: 1975-11-20
Abstract: In the purification of helium used as primary coolent in a gas-cooled high temperature nuclear reactor, by removal of impurities therein such as CO, CO2, H2, O2, radioactive iodine and radioactive gases, successive steps comprise the removal of the radioactive iodine, the conversion of the CO and CO2 with H2 to give H2O and CH4, the removal of the H2O and the removal of the O2, N2, CH4 and radioactive gases. The method provides a simpler and more efficient technique of removal of CO2 and H2 from the impure helium, having a lower capital cost than existing methods.
Patent DE-2552879-A1 (DE)
Title: Two stroke engine piston ring - is in multiple circular sections to avoid damage when run over ports
Inventor: MARIANI LAURO
IPC: F16J9/06
Filed: 1975-11-25
Abstract: The piston ring (5) is composed of a number of identical circular sectors. Each sector has a cross-section resembling an inverted U. A spring ring (6) fits inside the U and presses the sectors against the wall of the cylinder (3). With conventional piston rings used with two-stroke Diesel engines, there is a tendency for the ends of the ring to project into the cylinder ports as the piston passes them. This is liable to cause damage to the rings and may cause the piston to seize in the bore. A piston ring in separate sectors with an inner spring ring eliminates this source of failure.
Patent DE-2554973-A1 (DE)
Title: Railway goods wagon interior heating and cooling plant - has ventilator assisted air passed through dry ice or heat exchanger
Inventor: MUNSKE HELMUT
IPC: B60H1/32
Filed: 1975-12-06
Abstract: The combined process for heating and cooling the loading interiors of railway goods wagons uses dry ice for cooling and electric power for heating. Min. servicing is needed, and the equipment can be operated and checked by a single attendant. For interior cooling, air is conducted through the interior, passing through a dry ice installation (a) in the circuit, with the aid of ventilators (8), until the temperature has reached a previously determined ideal value. For heating, ventilator (11) assisted air is conducted through a heat-exchanger (12) until the temperature has likewise attained a previously determined level. The cooling or heating system may be switched on by an outside thermostat, (10) dependent on outside temperature. The heating assembly may be mounted on one side, and the cooling assembly on the other, in the top third of the wagon height.

Title: Pneumatic suspension for close set twin axles - having dampers between axles and trailing arms to each side of unit
Inventor: GIER KURT
IPC: B60G5/04
Filed: 1975-12-13
Abstract: The twin axle suspension has the axles supported at the ends of pairs of trailing arms (9) which are set fore and aft of the unit, so that the axles can be spaced as closely as possible. The adjoining sides of the axles are fitted with pneumatic dampers (14,15) set between the axles on extensions of the trailing arms, which are themselves located on sliding fittings on a central support (22). The close spaced array permits large loads on normal driving licences in some countries. It also enables the twin axle to be assembled using conventional components from a single trailing axle design. Lateral stability is provided by hydraulic dampers between the central support and the chassis.

Title: Automatic dialling generator for telephone calls - uses dialling electromagnets after raising handset esp. for monitoring
Inventor: MARESCH MICHAEL
IPC: H04M11/04
Filed: 1976-03-08
Abstract: The automatic dialling generator is for attaching to existing telephone terminals to make calls automatically without infringing the PO regulations and has a lifting mechanism to raise the handset and an automatic dialling device to select a stored subscriber number.
