Title: Magnetically sprung railway bogey - with opposing electromagnets and adjustable spacing damper to centralise magnet cores
Inventor: THEODORE CHARLES
IPC: B60G13/00
Filed: 1974-09-03
Abstract: The railway bogey has ferromagnetic cores (32) attached to the unsprung wheels and positioned between electromagnets (20, 22) attached to the sprung part of the suspension. The wheel axles are further linked to the rest of the bogey by a set of dampers (18) whose mechanical springs are backed up by adjustable hydraulic dampers. These ensure that the suspension assumes a means position, with the electromagnets equally spaced from the cores. The sprung and unsprung parts of the suspension are fitted with sensors to monitor the relative movement, as well as the rate of change of relative movement. a rapid feedback control adjusts the supply current to the electromagnets to compensate for any relative movement.

Title: Calculation of centre of area of characters - characters read by digital optical recognition
Inventor: WIEDEMEYER WERNER DIPL ING
IPC: G06V30/146
Filed: 1974-09-12
Abstract: A digital control unit provides a method of centring characters read by optical character recognition techniques based upon calculation of the centre of area. The character is considered as a number of segments and is read on a column by column basis by a line of photo diodes that synchronous by scan the characters. the controller calculates the number of area segments contained in each row to give an area function: F = summation of Zi from i = 1 to h. The moment characteristic (M) is then obtained by successive summations of areas in each row. the centre of area is then given by S = M/F. The complete computation involves two full adders, with matrix memory and counter control.

Title: Generator operating by means of magnetic repulsion - comprises two part eccentric rotor with repulsion taking place in crescent assembly
Inventor: OTT CARL DIPL KFM
IPC: H02K57/00
Filed: 1974-10-25
Abstract: The internal reluctance is reduced depending on the action of the eccentricity of the rotor within the stator and through the "like" polarity of the magnetic field systems of the rotor and stator in the reaction zone and through which both systems mutually repel one another. Example of such polarity is (N-N) operating in a reaction zone restricted to, at the most, (180 deg.) along its periphery, whereas the stator winding, running the full (360 deg.) is only active in the zone lying opposite the rotor magnets embracing the (180 deg.) periphery. Thus, the stator winding is formed as discrete coils uniformly displaced from one another and wound in series or parallel, but with attention to timing the "switch-off" of the coils in the zone of the crescent.

The degreasant and the rinsing medium are pref. fed at prescribed pressures into the individual welding zones, using a spray pistol fitted with a ring seal and a plug for the bore of the tubes, the two media being fed through the pistol. Efficient degreasing of the joint surfaces prior to automatic welding so that welds are obtd. which are free from defects, thus involving no subsequent work.

Title: Sender unit for vehicle flashing indicator - has astable transistorised saw tooth oscillator with monitoring circuit
Inventor: SEITTER WOLF
IPC: B60Q11/00

Inventor: OHL WOLF DIPL ING
IPC: H04Q1/46
Filed: 1975-08-23
Abstract: The telephone selective frequency receiver test circuit provides an alarm signal if the level between upper and lower code frequencies varies by more than 5dB. The incoming frequency groups are filtered and the two separate frequencies connected to the input of the tester. The signals pass to an upper or lower rectifier and smoothing circuit and to a gating circuit. The gating circuit controls the timing capacitors in the smooth circuit.

Title: Sugar extract satd. with gas esp. carbon di:oxide - with continuous recirculating flow propelled by injection of compressed air
Inventor: NIESTROJ JOACHIM
IPC: C13B20/06
Filed: 1977-02-02
Abstract: Juices, esp. sugar juices, are satd. with gas in contraflow to the juice entering the upper part of the tank. The juice is circulated at a rate several times greater than the feed rate of the juice into the tank. The juice is circulated from the bottom of the tank back to a point near the surface level, where it mixes with the newly entering juice. This circulating effect is produced by injecting compressed air upwards into the recirculation pipe. Pref., the air is injected in a finely divided form. Pref. proportion of air to juice is 1Nm3/m3. Thorough circulation is achieved without the drastic beating effect produced by rotating blades which tends to prevent the precipitation of calcium carbonate particles formed by the reaction of the carbon dioxide gas with the lime present in the sugar juice.
