Title: Holography
IPC: G03H5/00
Filed: 1969-10-13
Abstract: 1322337 Hologram display EMI Ltd 2 Oct 1970 [13 Oct 1969] 50230/69 Heading H4F A hologram of an object or area, produced by illuminating the object or area with coherent radiation e.g. of ultrasonic or radio wavelength, is displayed by modulating the intensity of the electron beam (or beams) of an electron tube device having a cathodo-chromic (dark trace) target in dependence upon the hologram, and illuminating the target with coherent light or visible wavelength. In a first embodiment, Fig. 1, reflected coherent radiation from object 1 (or radiation not reflected therefrom) and a reference beam from the same source are arranged to form are interference pattern (hologram) on a transducer 2 (or an array of transducers) which is arranged to scan the pattern (the transducer 2 and or the source may be moved). Alternatively the hologram may be transduced within the transducer 2 in response to the reflected coherent radiation and electric signals derived from means driving the source of illuminating radiation. The resulting electric signal is applied to modulate the electron beam of CRT 4 the target 7 of which is formed of cathodo-chromic material e.g. potassium chloride or potassium bromide, in which the absorption at optial wavelengths is dependent upon the intensity of the electron beam. The target may comprise a disc 7 of cathodo-chromic material which may have a reflective and conductive (aluminium) coating 8 which reflects incident coherent light passed through the window 9, or the target may comprise a substrate coated with cathodo-chromic material. Preferably the target disc 7 is wedge shaped so that the coherent radiation employed for viewing the hologram when directed at an angle through window 9 is not reflected from the front surface of the target towards the viewer or recording device. Between scans of the electron beam the target my be cleared by heating. In a second embodiment the cathodo-chromic target is used in place of the phosphor of an image intensifier. An infra-red hologram may be formed on the photocathode of the intensifier by using coherent infra-red radiation. A modulating electrode may be included in the intensifier which acts as an electronic shutter so that a hologram of a fast moving object may be made using a CW laser instead of a pulsed laser i.e. the arrangement may be used for continuously scanning an area for intrusion.

Filed: 1971-01-13
Abstract: 1324561 Maintaining electrolyte level in storage batteries OLDHAM INTERNATIONAL Ltd and H MORTON 29 Nov 1971 [13 Jan 1971] 1676/71 Heading H1B A secondary battery having means for simultaneously topping-up all the cells to the correct height of electrolyte has a lid 3 provided with an electrolyte channel 5 normally closed by a cover 7. The channel 5 extends lengthwise along the battery over all the cells and has, for each cell, an opening 4. A resiliently deformable tube 13 extends from each opening and, when the cover 7 is open, Fig. 2, the tubes extend downwards and water may flow from the channel 5 into the cells until the electrolyte level reaches the bottom of the tubes. Since air cannot now leave the cells, additional water cannot enter. On closure of the cover 7 by movement about a pivot 15, projections 14 on the cover deflect the tubes 13 and raise them above the electrolyte level, Fig. 1, so that the tubes now serve to vent the cells. The cover 7 has a vent hole 6. In a modification (Figs. 5, 6, not shown) the projections 14 are shorter so that when the cover is open they are withdrawn from the tubes 13 to permit a hydrometer to be inserted. When the cover is closed the short projections 14 cause the tubes to react against fixed projections in the battery housing whereby the tubes are raised above the electrolyte level. In another embodiment (Figs. 7, 8, not shown) the projections 14 each consist of a pair of spaced side-by-side members so that a hydrometer may be inserted in the space when the cover is open. In another embodiment (Fig. 9, not shown) the cover 7 is detachable and clipped in position and the upper ends of the tubes 13 are of bellows construction to improve flexibility.

A chamber 14 defined between diaphragm 7 and lens 9 contains an electrically insulating mineral oil. The bottom face of unit 21 operates half as a transmitter and half as a receiver, the unit producing a pencil beam signal which is modified by lens 9 and transmitted through chamber 14 and diaphragm 7 to the foetus. The reflected signal is fed through an amplifier with automatic gain control for smoothing variations due to foetal movement, a band pass amplifier, a detector with a dead. time generator which inactivates the detector for a period following a heart beart, and a rate meter for producing an output signal representing the heart beat rate. A reading may be given on a visual or chart recorder.
