Patent GB-765714-A (GB)
Abstract: 765,714. Theodolites. " LICENCIA " TALALMANYOKAT ERTEKESITO VALLALAT. Nov. 26, 1954 [Nov. 28, 1953], No. 34381/54. Class 97(2) A theodolite or like instrument consists of a top portion and a bottom portion with inter-engaging means such as a prism on the bottom part and a socket for receiving the prism on the top part, so that the two parts when fitted together cannot rotate relatively to one another. As shown in Fig. 1, a prism 10, e.g. of triangular crosssection, is formed on a trunnion 12 rotatable in the base 13, which is supported by adjustable screws 27 on a base plate 28. A ring 14 which embraces the lower part of trunnion 12 and may be clamped thereto by a clamping screw 16, has a projection 17 engagaing a vernier screw (not shown) for fine adjustment about the vertical axis. A prolongation 22 of the prism 10 can be used as a target when the top part is removed. A housing 24 contained in a bore in trunnion 12 has an opal glass disc 23 illuminated by an electric lamp 25, which acts as a target when viewed from below through an opening in the base plate 28. The top part of the instrument has a sleeve 11 (see also Fig. 3) which fits over the prism 10 and may be clamped thereto by a screw 42. The instrument frame has a bearing ring 32 with two conical surfaces forming part of a ball bearing by which the frame rotates on sleeve 11, the arrangement being such that the instrument may be inverted, the top part in that case hanging from the bottom part. The frame has a clamping ring and vernier adjustment, similar to those described in relation to trunnion 12. The frame supports an azimuthal telescope and a 'graduated vertical circle 47, fitted respectively with spirit levels 46, 48 and vernier adjustments 50, 49. The spirit levels 46, 48 have graduations 55, 56 extending downwards to be readable from the side. The instrument frame 31 carries a transparent graduated scale plate 51, viewed through an eyepiece 52, Fig. 4, and a prism 53, and is illuminated through an aperture 54 in the casing.

Title: Automatic flow control
IPC: G05D7/06
Filed: 1979-05-10
Abstract: A liquid drop rate controller for controlling flow of fluid from an infusion fluid reservoir 2 to an intravenous infusion site which includes a cam means 10 in the form of a wheel 24 mounted eccentrically on a shaft which varies the compression on a flexible tube 4 carrying the liquid; the controller 12 senses the actual drip rate optically and compares this to a preselected desired drip rate set in thumbwheel switches 22 and varies the compression accordingly. The comparison is accomplished electronically by the generation of a time base whose frequency is controlled by the selected drip rate; this time base is compared to the actual drip rate observed by the optical sensing means, and the cam means is controlled in relation to an error signal obtained through the comparison. The controller 12 includes a separate comparison circuit which comes into operation at low drip rates so to increase accuracy of control. <IMAGE>

Title: Separating ethane from methane
IPC: C07C7/13
Filed: 1980-05-20
Abstract: Ethane is separated from methane by passing a gaseous mixture of the ethane and the methane (plus a carrier gas if desired, e.g. helium, which can be 95% of the total volume) at a temperature from 150K to 400K and at a pressure from 1 to 80 bar through a bed of an adsorber having an effective molecular sieve size from 4 ANGSTROM  to 10 ANGSTROM  until the methane concentration per unit volume of gas leaving the bed is at least as great as the methane concentration per unit volume of the mixture passing into the bed (at the same pressure), discontinuing the passage of the mixture (but optionally allowing any carrier gas to continue to flow) and collecting the gas which is release. That gas is relatively enriched in ethane, often containing only ethane (plus any carrier gas).

Title: Apparatus for Regenerating Signals Within a Frequency Band
IPC: H04K3/00
Filed: 1980-11-06
Abstract: Apparatus for generating signals to interfere with or jam signals detected as unfriendly in a given input frequency band comprises a spectrum analyzer circuit 20 using surface acoustic wave (SAW) chirp filters (22, 23) to provide a transformation of input frequency signals to a series of time displaced signals in a linear frequency-to-time relationship. The analyzer circuit uses the SAW devices to perform multiply-convolve functions that separate the different frequency signals in time and the analyzer is repetitively triggered to perform a spectrum analysis. The time series signals are selectively applied to a frequency synthesizer (40) having a time-to-frequency relationship that matches the analyzer characteristic so as to regenerate signals at the input frequencies. The synthesizer uses two matched chirp filters (41, 42) one activated by a fixed time signal and the other by the time series to generate swept frequencies that are mixed to provide the required frequency outputs. The time series is processed (30) to inhibit those signals corresponding to frequencies identified as friendly. <IMAGE>
