Patent GB-635499-A (GB)
Abstract: 635,499. Examining bottles photo-electrically. STOATE, N. P., SHEPHEARD, G. E., and U.D. ENGINEERING CO., Ltd. June 18, 1947, No. 16113. [Class 40 (iii)] The bottoms of transparent vessels, for example milk bottles, are scanned photo-electrically to detect the presence of foreign bodies, by a succession of apertures, so arranged that the total aperture area through which light passes at any instant is equal to the area of one aperture. As shown, bottles brought by a conveyer 14 are caused by guides to pass over a hole 22 in the support, this hole being a little smaller than the bottom of the bottle. Light passes from a source above the bottle through its bottom and the hole 22 to a photo-cell below. A disc 27 in which are cut a series of holes 29 arranged spirally, rotates between the photo-cell and the bottle support; and its speed is sufficient to ensure that the whole bottom of the bottle is examined in the time it takes the bottle to pass over the hole 22. The sides of the hole 22 are stepped, as shown in Fig. 5, so that as one aperture leaves the light path through the bottom and another enters it the total area of light passing to the photo-cell is substantially constant and is equal to that of one aperture. If a foreign body reduces the light to the photo-cell an amplifier 32 operates an electromagnet 35 (Fig. 6) and breaks the circuit of a further electromagnet 34 which normally holds an arm 33 out of the path of the bottle so that the movement of the bottles is arrested, an alarm may also be operated. The circuit of electromagnet 35 includes a contact 38 which must be closed by an arm 39 actuated by the bottles themselves before the electromagnet can operate. The control switch 38 may be operated photoelectrically. Arm 33 may be arranged to project into the path of the bottle and to be removed only if the bottle is clean. Variations in the thickness of the bottom of the bottles may be compensated for by positioning a suitable filter between the scanning disc and the photo-cell, and the insertion of a blocking condenser in one of the coupling circuits of the amplifier will render the apparatus non- responsive to changes of bottle colour.
Patent GB-675313-A (GB)
Abstract: 675,313. Particle accelerators; travelling- wave tubes. ASSOCIATED ELECTRICAL INDUSTRIES, Ltd. Dec. 27, 1950 [Nov. 30, 1949], No. 30748/49. Class 39 (i). In a travelling-wave linear proton accelerator in which the proton beam is projected along the axis of a helix or helicoidal waveguide, an electron beam is also projected along the axis of the helix to concentrate the proton beam. The electron beam may be projected in either direction, but preferably in the opposite direction to the proton beam. An axial magnetic field is provided for focusing the electron beam. The angle of the helix is graduated to effect progressive acceleration of the proton beam. As shown, magnets 4, 5 at each end of the helix 1 separate the electron and proton beams EB, PB. To accelerate the proton beam, radio frequency power is fed into the helix through a phase adjusting device 7. The radio frequency power is fed back from the output end of the helix to the device 7. The target 6 for the proton beam may be a foil or gas target. To vary the energy of the proton beam, the physical length of the helix may be varied, or its effective length may be varied by adding a cavity resonator and varying the energy given to the beam by the cavity.

Title: Device for study of the alimentary canal
IPC: A61B5/07
Filed: 1979-03-21
Abstract: A swallowable capsule for obtaining samples of gastric and/ or intestinal fluids, the capsule defining an inner fluid receiving chamber (18) having an inlet port (17) which is normally sealed off from the exterior of the capsule by way of a blocking means including a mass (21) the properties of which change upon contact with the suitable fluids present in the digestive tract, causing the means to communicate the inlet port (17) with the outside of the capsule allowing a sample of the fluid to be aspirated into the chamber (18). Located within the chamber is a closing means (9, 12, 14) normally maintained in a flow permitting position by a mass (28) which glues the necessary parts of the closing means together in such a way that the parts cannot move, so that the action of the closing means is neutralized. This mass (28) is responsive to contact with the suitable fluids of the alimentary canal to permit the closing means (9, 12, 14) to operate and seal off the chamber (18) so that the sample is secured from contamination during its further travel through the rest of the digestive tract. With the use of a different mass (21, 28), which will dissolve in gastric juice or which will not dissolve until after contact with the alkaline contents of the small intestine, the capsule may be used to collect a sample of gastric juice or intestinal juice, An indicator of free HCl, or alternatively of lactic acid, may be provided in the chamber (18) of the capsule, the indicator reacting to the presence of free HCl, or of lactic acid in the sample to change the color of the sample, which may be viewed through a transparent portion of the wall of the capsule.
