Title: Improvements relating to diagnostic x-ray equipment
Inventor: WHITEHEAD GEOFFREY
IPC: A61B6/08
Filed: 1960-05-11
Abstract: 918,310. X-ray protection devices. WATSON & SONS (ELECTRO-MEDICAL) Ltd. April 28, 1961 [May 11, 1960], No. 16548/60. Class 98 (1). A gonad protector consists of a number of screening segments opaque to both light and X-rays, arranged on a transparent carrier, so that an appropriate one of the segments may be positioned to protect the gonads of a patient under X-ray examination. The invention is intended for use with an optical field indicator, in which a light source is arranged to have a virtual position at the focus of the X-ray tube, so that the relative position of patient and light source can then be adjusted until the patch of light falling on the patient corresponds in size and position with the region required for radiographic examination. Thus this preliminary positioning can be carried out without exposing the patient to unnecessary irradiation. The protector itself consists of a plurality of lead segments attached to a plastic sheet. The sheet may be so mounted in guides on the face of the field indicator as merely to slide in one direction only. Fig. 1 shows an alternative in which a number of lead segments 6, 7, 8, 9 are fixed on a plastic disc 5 which is rotatably mounted on a sheet 4, itself slidable. Fig. 2 (not shown), is an alternative form of rotatable mounting. The lead segments can be of different shapes to suit children or adults of either sex.

Patent GB-794643-A (GB)
Title: Improvements in or relating to processes for the production of pure germanium
IPC: C22B41/00
Filed: 1954-04-15
Abstract: Germanium is produced from germanium dioxide by reduction with hydrogen in a vessel containing carbon and/or silicon, the formation of impurities produced by the carbon and/or silicon in the vessel being inhibited by addition to the hydrogen of one or more of GeO, H2O and CO, whereby the reactions tending to introduce the said impurities are suppressed or restrained.  In examples the dioxide is reduced at a temperature of 650 DEG C. by hydrogen containing water vapour the partial pressure of which corresponds to saturation at 0 DEG C.  Alternatively CO2 may be added to the hydrogen e.g. in an amount of 0.1 per cent. Preferably the germanium dioxide used is one which has been prepared in a silicon-free vessel, e.g. a vessel of plastic synthetic resin.  Specification 794,642 also is referred to.

A transportation system comprises a conveyer 41a which carries (Fig. 9) a vehicle M having a skirt 63 defining a plenum chamber 62 which has a free lower area bounding a track 46 and controllable means 50 to supply the chamber 62 with pressure fluid so that the vehicle M can be lifted by the fluid and disengaged from the conveyer 41a. As shown, the conveyer 41a comprises spaced endless conveyer belts. Orifices 50 supply the chamber 62 with air when a lever 57 on the vehicle M is operated to engage a member 56 connected to valves 51. The track 46 is pivotally mounted at 60 so that when the valves 51 are closed, air pressure builds up in a chamber 47 and lifts the track upwardly (Fig. 8, not shown) into a position suitable for conveyance of the vehicle M by the belts 41a. In this condition, the skirt 63 is retractable. When the vehicle M is airborne, it can traverse a curved track (Fig. 10, not shown) between straight conveyer sections. The sides of the curved track may have guides on each side of the track in the form of endless conveyer belts. In a modification (Figs. 1 and 4), the vehicle M is suspended from an overhead endless belt la. Orifices 31 in a track 18 may be obliquely directed, so as to deflect the vehicle laterally from the conveyer.

Abstract: 1392503 Measuring dimensions electrically M POSSATI [trading as APPARECCHI ELETTRONICI MARPOSS] 14 April 1972 [14 April 1971] 17470/72 Heading G1N An electronic battery fed measuring instrument such as a dimension gauge includes an element which is moved by a workpiece when it is placed in the measuring position to permit the battery to feed the instrument, the battery being in open circuit in the absence of the workpiece. The feeler gauge of the instrument is connected to a ferromagnetic element 20 coupling transformer 14 forming part of a transistor 11 oscillator. In the absence of a workpiece element 20 is in the lower position so that the inductance in the collector circuit of the transistor 11 is such that the oscillator does not oscillate and due to the high resistor 12 the battery discharge current is very small. When the workpiece is in the measuring position the element 20 moves upwards by an amount proportional to the dimension of the workpiece and the oscillator commences to oscillate. Positive feedback from the output of detector 18 causes the oscillations to be intensified and stabilized to an amplitude determined by the position of element 20. Meter 19 indicates the amplitude of the rectified oscillations and hence dimension of the workpiece. Removal of the workpiece causes the oscillations to cease and the battery 13 to be connected in substantially open circuit again.
