Title: Equal dose determination by X:ray computer tomograph - using alternative gamma source for directly determining gamma absorption
Inventor: BAGGE ERICH PROF DR
IPC: A61N5/10
Filed: 1975-11-20
Abstract: The Parent Patent describes the use of an X-ray computer tomograph for converting the local absorption coeffts. obtd. from the tomograph into electrom densities. The objective is to obtain refined radiation therapy. In this patent an alternative nuclear gamma radiation source is connected to the equipment instead of the X-ray source. This enables the distribution pattern for the gamm-absorption coeffts., which is also a determining factor in the therapy, to be measured. Pref. the distribution pattern of the absorption coeffts. obtd. in the 100 KeV and in the MeV range, is used for calculating the absorption coeffts. fior higher quantum energies above the 1 MeV range, allowing for the pair-forming processes which occur. This distribution pattern in turn enables the local dose rate distribution to be determined. By introducing the measurement of the gamm-absorption coefficients for local regions of the body, a considerable amount of calculation is eliminated. Further conversions of the observed absorption coeffts. are no longer required.

Title: Enhanced brake control for hydraulic drive vehicle - with brake pressure switch setting drive to neutral
Inventor: FRECH FRIEDRICH DIPL ING
IPC: B60T1/08
Filed: 1975-12-18
Abstract: The heavy vehicle is propelled by a hydraulic drive in which an electro-magnetic pump delivers fluid for the transmission circuit. The brakes are hydraulic and are interlocked with the transmission in such a way that when the brakes are applied the output of the pump is inhibited so that a transmission braking effect reinforces the normal brakes. A brake pressure valve, operates a control switch to control a relay which switches off the electro-magnets of the pump. The heavy vehicle is thus safely retarded with a minimum of brake wear and less chance of brake face. A manual switch can be set to inhibit the transmission brake on icy surfaces, where a careful manual control is required.

Title: Cleaning and polishing of capsules - by impact against electrically charged screen followed by tumbling in napped fabric lined drum
Inventor: CHAMPION ROBERT JAMES
IPC: B08B7/04
Filed: 1977-08-08
Abstract: Recently-filled capsules are impelled against one surface of an electrically charged screen. Air is drawn through the screen from the other surface to draw off dust released from the surface of the capsules. The capsules fall into a delivery passage which carries them to a buffing drum where any residual dust is removed from the capsule prior to polishing. Pref. the drum is rotatable and is lined with a napped fabric e.g. a polyester pile fabric. If desired a second smaller tube having a napped outer cover fits within the first tube. Pref. the drum is rotated by a pair of rollers in which the drum is cradled, a motor driving one of the rollers. The appts. is used to clean and polish capsules which have been filled with finely divided material e.g. powdered pharmaceuticals. The appts. efficiently cleans and polishes the capsules including the crevice around the middle of the capsule. The use of a napped fabric in the polishing drum is cheaper than the use of lamb's wool belts.
