Title: Improvements in and relating to logs for measuring the distance travelled by water-borne vessels
IPC: G01P5/07
Filed: 1934-05-29
Abstract: 437,829. Ships' logs. AMPENOFF, W. P., 36, Park Drive, Golders Green, ROCKALL, G. A., 22, Winslow Road, Hammersmith, and ROCKALL, W. A. E., 11, Hansard Mews, Kensington, all in London. May 29, 1934, Nos. 15997 and 31135. [Class 97 (ii)] A submerged chamber containing a make-andbreak device driven by the shaft of a rotator is supplied with oil from an oil reservoir at a pressure not more than sufficient to prevent the entry of water, i.e. by means controlled by the water pressure outside the ship. As shown, the submerged chamber a, similar to those described in Specifications 177,187 and 193,254, [both in Class 97 (ii)], is supported in a guard tube f carried by an outboard arm g. The latter extends from the end of a shaft g<x> passing through a gland r<x> at the top of a casing r surrounding the opening h in the ship's hull i. The oil reservoir is a flexible corrugated metal cylinder b fixed at the top to a cylindrical guide o and at the bottom n to the top of a second flexible corrugated metal cylinder p, the bottom of which is secured to the bottom of the guide o. The cylinder b communicates with the chamber a through conduits d, c, and non- return valve e. The cylinder p communicates with the water in which the chamber a is immersed through conduit q and casing r and is of slightly larger diameter than the cylinder b so that the oil pressure in the chamber a is sufficiently in excess of the pressure of the external water. A contact lever s actuated by movement of the cylinder p operates an electrically controlled inlet valve or a pump for maintaining the oil supply in the reservoir b. In a modification the conduit q is connected to a tube within the shaft g<x> and communicating either with an opening in the front of the arm g or with an annular groove formed on the arm g and surrounded by a rotatable sleeve provided with an aperture which may be caused to face any desired direction. In a further modification, Fig. 8, an oil reservoir bx is supported in a guard tube f<x> beneath the chamber a to which it is connected through channel 32 and non- return valve 33. The reservoir b<x> has a flexible wall 34 facing the direction of advance and is connected to an oil supply tank through channel 35 and non-return valve 36. The rotator shaft or its bearing, or both, may have a helical groove to impart an outward tendency to the film of oil between them.

Patent GB-672156-A (GB)
Title: Wide band microwave spectroscopy
IPC: G01N22/00
Filed: 1950-06-30
Abstract: 672,156. Microwave spectroscopy. RADIO CORPORATION OF AMERICA. June 30, 1950 [July 16, 1949], No. 16420/50. Class 37. Relates to a micro-wave spectroscope in which micro-wave oscillations, whose frequency is repeatedly swept over a desired range, are applied to a container in which is the gas to be analysed. The electrical output from the container is characterized not only by gaps in the spectrum due to absorption by the gas, but also by variations due to the nature of the container. According to the invention, the variations due to the nature of the container are eliminated by providing in the container a Stark electrode fed with a potential modulated at a frequency different from that of the sweep frequency of the micro-wave oscillations, so that the variations due to the gas are correspondingly modulated and can be selected by a suitable filter. As shown in Fig. 1, an ultra-high frequency oscillator 10 is modulated in mixer 14 by a high frequency oscillation from 12 which varies regularly over a desired range; a filter 15 selects the upper or lower side-band for application to the container 16 whose output is rectified at 19, amplified at 20 and fed to a cathode-ray tube or chart recorder 21. The container 16 contains a Stark electrode 23 fed from a source 22 providing a potential varying at a frequency markedly higher than the sweep frequency of oscillator 12, and amplifier 20 is tuned to this frequency so as to be oblivious to the variations due to the container 16. The recorder 21 has its time base controlled by the sweep frequency of oscillator 12. As shown in Fig. 2, an ultra-high frequency oscillator 10A is modulated by varying highfrequency oscillator 13A, to supply a varying frequency to container 16A which includes a Stark electrode 23A as in Fig. 1. The output is rectified at 19, amplified at 20 and applied over amplifier 30 to the cathode-ray oscillograph 21A. Since the response of the container varies with frequency, the output may be led from 25 to a detector 26 to provide an A.V.C. potential for controlling the output of amplifier 20 and thus eliminate variations in the spectra due to this cause. This correction may also be applied to the circuit of Fig. 1, Fig. 3 (not shown).

Abstract: 889,298. Attachment for correcting parallax of viewfinders. KIRCHHOFF, K. May 23, 1958 [May 25, 1957], No. 16594/58. Classes 97(1) and 98(1). For eliminating parallax between the viewfinder and the objective of a camera for closeups, an attachment is provided with at least one optical wedge device with a continuously adjustable deflection, a scale arranged to indicate the range for which the viewfinder is set free from parallax with the objective, and a mounting arm which is releasably mountable on the camera. As shown the adjustable wedge may be a pair of wedge prisms 1, 2 rotatable in the body 5 about the axis 16 by means of knobs 8, 9 and each cooperating with a double range scale 11 Fig. 7 (not shown), a mask 14 with an off-axis aperture may be disposed between the wedges to assist the parallax correction. Instead of the wedge prisms, a plano-concave and a plano-convex lens combination of zero power may be provided, the two lenses being asymmetrical spherical segments and in effect combined prisms and lenses. The body 5 of the optical unit may be mounted by a ring 12 attached to an arm 17 having a foot 18 for mounting in an accessory shoe on the camera or attached to an arm 33 pivoted to a mount engaging about the objective on the camera, the mount consisting either of separable clamping arms 29, 30 adjusted by a screw 28 or of a spring fork member. In a further modification (Fig. 12 not shown), the optical deflection device comprises a pair of wedge prisms rotated through bevel gearing, the knob operating the gearing bearing the range scale. In still further arrangements (Figs. 10, 11 not shown), an afocal pair of planospherical lenses are relatively adjustable to provide the parallax correction.
