Title: Nuclear fired boiler feed preheater-degasser - with reduced radiation hazard
Inventor: HINTERHOELZL JOHANNES
IPC: F28F9/00
Filed: 1968-11-30
Abstract: The device consists of a vessel placed directly beneath the main condenser. The upper section of the vessel contains degassing baffles, over which the condensate passes mixing at the same time with a portion of hot fluid direct from the turbine, which heats it to above the saturated vapour pressure of the vessel, causes some flash evaporation and thus degasses it. The lower portion of the vessel has for boiler feed holding capacity sufficient to ensure that the dwell time is long enough to allow the decay of any radioactive contamination and thus make feed pump maintenance problems less hazardous. Some of the maintenance problems encountered in nuclear power stations with direct recycle of the working fluid, can be overcome by using this design of feed degasser preheater.

Title: Preparation of hydrooxyalkyl esters of benzene
Inventor: RICHARD LARKIN DONALD
IPC: G06K7/14
Filed: 1969-02-24
Abstract: Bis-hydroxyalkyl esters of benzene dicarboxilic acids are produced by suspending 1 mole of the acid in nitrobenzene or a nitrobenzene/nitrotoluene mixture and reacting at 80 deg.-200 deg.C (especially 100 deg.-150 deg.C), with 1.7 to 5 moles, (especially 2 to 4 moles), of alkylene oxide in the presence of a soluble catalyst such as an amine, arsine, stibine, phosphine or quaternary ammonium compound. The reaction is stopped when 75 to 98% of the acid has reacted; time required is 10 to 180 minutes. Similar processes exist using different dispersion media. These new media give conversions and the products have a low dialkylene glycol contamination. Polymer prepared from the ester is suitable for tyre cord. The solubility of the ester in the media is high acid concentrations may be used and still give a yield which is entirely soluble. The acid is completely insoluble and separation is easy.

Patent DE-2044199-A1 (DE)
Title: Programme controlled sheet metal bending - using open tooling
IPC: B21D5/02
Filed: 1970-09-07
Abstract: Controlled or automatic unrestrained bending of sheet metal between a punch and an open V-block type tool is carried out in power presses in which the path of the punch is not limited and which may be stopped at any point of its stroke. The workpiece is deformed from a definite starting shape to a definite end shape. This is achieved with the help of measuring probe which monitors either half or the whole included angle of deformation of the workpiece and thus the angle by which it has been deformed as a control value x, which is compared with a programmed value xk, which is determined by the stroke of the press stand. It thus permits at any time the calculation of the deviation xw = x - xk, which after a preset interval is transformed into an adjustment working stroke.

Title: Suspension system for steered wheels on vehicles - has load on wheels increases vehicle frame lifts due to springing
Inventor: RUF GEBHARD DIPL ING
IPC: B60G11/00
Filed: 1973-06-26
Abstract: The wheel carrier and stub axle is suspended on the track rods with a spring support between the carrier and the vehicle chassis. The design provides reduced castor angle and hence improved brake stability without adversely affecting the "ride" characteristic. The connecting parts for the spring elements are outside the pivoting axis of the wheel carrier. As shocks, due to road unevenness, are applied to the wheels, the spring lengths alter. This causes the frame to lift. Several designs of spring are shown. Where the spring is pressure loaded the connecting points are on both sides of the pivot axis in a vertical plane. Where the spring is tension operated, the connecting points are both on one side of the axis.

Abstract: Milled materials feeder for a hammer mill has a horizontal cover at the top end of the feed channel. Preferably, the material flows above the mill and is metered by a shaker trough; the noise due to the suction of air by the mill fan is reduced by the cover, beneath which the free end of the trough can engage, and the air flow is interrupted. The mill housing encloses the milling chamber and the fan which engages around it, and the trough is above the housing, with the material fed from it into the vertical feed channel.
Patent DE-2341355-A1 (DE)
Title: Temperature controlled valve with three way flow - uses 'O' ring as poppet to provide improved sealing
Inventor: KURZ MANFRED
IPC: G05D23/185
Filed: 1973-08-16
Abstract: A central poppet is displaced by the output shaft of a temperature sensitive input stage against the action of two coil springs. The poppet seal is formed by an 'O' ring that seats either against an insert in the low temperature position or against the housing in the high temperature position. Since the poppet is balanced between the two coil springs any excess temperatures do not result in overload of the input stage. The valve operates as a 3-way directional valve, transferring flow from an input to two outputs in a proportional mode between upper and lower temperatures with total shut-off of one output at the extreme values. Use of an 'O' ring seal as a poppet is more efficient than a tangential sliding seal arrangement.
