Title: Horizontal centrifugal ppipe casting moulds - selectively quenched after tempering
IPC: B22D13/10
Filed: 1973-05-04
Abstract: Each fresh centrifugal casting mould is quenched from the inside prior to being quenched from the outside after its final tempering treatment before being put into service thereby generating compressive stresses. Used moulds are prevented from cooling down after each casting operation by stopping the coolant flow round their exterior whence the whole mould wall is heated from the interior to just below tempering temp. following which the mould is quenched first from the inside and then from the outside. The treatment results in an extension of the mould service life.

Title: Control of high voltage equipment - involves providing double transformer coupling via single turn windings and coil with many turns
IPC: H01F38/24
Filed: 1975-02-20
Abstract: A transformer coupled system provides control of HV equipment or derives measurements from it. The arrangement provides double isolation of the control or measurement source from the potentially hazardoud equipment. The input or low tension transformer is a closed magnetic circuit fed from an orthodox source via a multiturn coil. A single turn acts as the transformer secondary and is led to the second transformer by two heavily insulated wires. The second transformer is again a closed magnetic circuit with a single turn primary winding fed from the first transformer. The core itself is held at the same potential as the high voltage unit it controls, which is coupled to it by an orthodox secondary winding.

Title: Load controlled train pneumatic brakes - with minimum pressure control to ensure sufficient base pressure to overcome system resistance
IPC: B60T8/18
Filed: 1975-10-29
Abstract: The train pneumatic brakes are held off by a first pressure line which is vented to release the brakes for braking, after which a second pressure line is used to provide an increasing braking force. This second braking force is modulated by load sensors to adjust the braking of each wagon w.r.t. its loading. The control lines to each wagon are fitted with a special control valve bridging a low restricting valve to provide an initial braking force irrespective of the setting of the load sensors. This force is sufficient to overcome any friction forces in the braking system and provides a starting pressure for the load sensitive braking.

Title: Automatic grinding wheel dressing system - carries out redressing operation if duration of final rectifying phase exceeds specified value
IPC: B24B49/04
Filed: 1976-05-12
Abstract: A grinding wheel dressing system uses the time taken to carry out the final rectifying phase to gauge the necessity for redressing. When this time exceeds a specified value the grinder is redressed. The dimensions of the workpiece are continuously monitored during rectification. The speed of grinder advance is automatically reduced when specified workpiece dimensions are attained. The reduced speed or grinder advance is then maintained until the specified finished workpiece dimensions obtain. At this juncture the rectification terminates, a signal is transmitted to a time comparator, and the necessity to redress the grinder is assessed. An adjustable timer may be activated by a signal at the onset of the final rectification phase. After a time interval the timer emits and displays a signal. Unless the specified signal is already displayed redressing ensues.
