Patent GB-2041867-A (GB)
Title: Drive Mechanism
IPC: B66D1/74
Filed: 1980-01-31
Abstract: A drive mechanism for travel along a vertically hanging elongate flexible member such as a wire rope (2) comprises a carrier (6) which supports a wheel (4) around which the rope passes. The rope is pressed into a groove of the wheel (4) by pressure applying means in the form of a roller chain (8). The force applied by the chain (8) derives from the weight of a cradle suspended from a shackle (14). Rotation of the wheel (4) causes the mechanism to travel up and down the rope. A brake mechanism prevents the drive mechanism from running down the rope (2) when drive to the wheel (4) is interrupted. <IMAGE>

Title: Improvements relating to weighing devices
IPC: G01G3/16
Filed: 1980-04-15
Abstract: A weighing device uses frequency measurement to determine weight. One body (3) is decoupled by springs (2) from the environment (1) and another body (8) is spring (9) connected to it, so that both bodies can oscillate in one mode in an effectively isolated system. The oscillations are electromagnetically generated, but when a certain amplitude is attained the drive is cut off and the system resonates freely. The frequency varies with the mass of the bodies, and so a load on one can be weighed by reference to the frequency, which can be detected through the electromagnetic means (12) which provided the initial drive pulses. <IMAGE>
Patent GB-2050686-A (GB)
Title: Apparatus for Analyzing Liquid Samples with a Mass Spectrometer
IPC: G01N30/30
Filed: 1980-04-17
Abstract: In apparatus for analyzing liquid samples by a mass spectrometer, a stream of liquid droplets of the sample formed by probe 11 is expelled as droplets into desolvation chamber 37, the droplets evaporated therein and the evaporated materials injected into the spectrometer source region. In some embodiments, no solvent or solute is pumped out of the desolvation chamber during transit; discrimination against highly volatile materials is thereby prevented. The apparatus may be used as an interface between a liquid chromatograph and the mass spectrometer. Temperature control is by circulating liquid 30, chamber 37 has non-reactive walls (e.g. Au), and filter 28 prevents clogging. Aperture and droplet sizes are specified. The length of chamber 37 may be variable (Fig. 2, not shown), and temperature controlled by an infra red heater. An acoustic transducer (e.g. piezo-electric) may stimulate the probe to break up the liquid stream into droplets. Tribo- electric jet-exit port reaction allows focussing by eletrostatic plates, and charging also encourages repulsion and minimises coalescence. Increase of surface charge density with desolvation also encourages the droplets to further break up and speed the evaporation process. <IMAGE>

Title: Setting recording level in a tape recorder
IPC: G11B27/34
Filed: 1981-03-24
Abstract: To obtain an optimum recording level on a tape T a comparator 30 (Fig. 9) compares the level of the signal to be recorded from input 14 with the output of a playback amplifier 24, any level difference being registered on an indicator 34. The recording level is manually increased by a control 16 to a level just below that at which indicator 34 starts to register a level difference in order to obtain an optimum recording level at point A (Fig. 4) on the input/output characteristic of the tape. A  comparator control 32 is initially adjusted to give a zero indication on indicator 34 with a switch 20 set to position 20a. A delay line 40 compensates for the spacing between the recording and playback heads 10, 12, and a control 50 is adjusted to compensate for differences in recording sensitivity of different tape types. The inputs to comparator 30 may be supplied via high-pass filter 60, 62 which can be selectively bypassed by means of switches 70, 72. A switch 80 (Fig. 10) may be provided to selectively connect level control 16 to the line input 14 or to an adjustable frequency test oscillator 82. <IMAGE>
Patent GB-2095652-A (GB)
Title: Method of making oxygen-free gas from oxygen-containing gas
IPC: C01B3/00
Filed: 1981-03-24
Abstract: An oxygen-containing gas (e.g. air) is passed (from conduit 6) into an oxygen-removal fluidized bed (in space 1) of particles including particles containing reactive CaS. The rate of oxygen supply relative to the reactive CaS content of the oxygen removal bed is less than the stoichiometric amount required for the highly exothermic oxidation of all CaS to CaSO4, and the temperature of the oxygen-removal bed is maintained below the temperature at which CaS is oxidized to CaO + SO2 by passing an oxygen-containing gas (e.g. air) through a heat-transfer coil immersed in the oxygen-removal bed. Particles are transferred from the oxygen-removal bed (via port 3) to an oxidation bed (space 7) fluidized by heated oxygen-containing gas from the heat-transfer coil whereby the remaining CaS is exothermically oxidized to CaSO4. The CaSO4 of the hot particles is endothermically reduced to CaS by a fuel in a fluidized reducing bed (space 8) and the resulting CaS-containing particles are transferred to the oxygen-removal bed (space 1) for further use. <IMAGE>

Patent GB-2081587-A (GB)
Title: A hydro-air vibrator massage device
IPC: A61H33/02
Filed: 1981-02-12
Abstract: It is useful in self applied hydro massage therapy to apply a vigorous massage to the body with a minimum of exertion by the user of the device. The invention comprises a water massage device with entrained air that is held against the region to be massaged. Mechanical displacement of the device coupled with pulsations in the water-air flow create a gentle massage. Air is entrained by passing a high velocity water jet (112) across an air gap (116) and through a receiving tube (120) into a rotor chamber (122). Differential pressures developed in the housing establishes an air draw through the receiving tube into the housing. An eccentrically weighted rotor (130) revolves under the impact of the jet (112) causing the entire device to counter rotate creating the massage displacement. Each blade of the rotor develops a high pressure leading zone which sweeps away spent water. Each blade also develops a low pressure trailing zone as the blade passes the receiving tube, which favors the air draw. The invention thus applies a vigorous massage to the body by means of the air and water stream expelled therefrom. This action is intensified by the automatic counter-revolution of the device imparted thereto by the excentrically weighted rotor (130).
Patent GB-2093228-A (GB)
Title: Automatic Control of Air-to-fuel Ratio
IPC: F02D41/14
Filed: 1982-02-10
Abstract: A method for controlling the air- to-fuel ratio of the mixture fed to an engine or other combustion device has the air-to-fuel ratio periodically altered towards stoichiometric into the response range of a conventional exhaust gas sensor. The output of the sensor at stoichiometric establishes a reference point setting of the air-to- fuel ratio proportioning device (e.g., carburetor) whose adjusting element is then moved a selected distance away from its setting point to provide a selected value of air fuel ratio which may be outside the normal response range of the sensor, either rich or lean of stoichiometric. The apparatus described includes a sensor 181 which generates an output signal which is compared against a reference signal by a comparator 28. When the output signal exceeds (or falls below) the reference signal, a timer B allows the proportioning device 42 adjusting element to be moved in the desired direction for a stated interval of time. A separate timer A operates the adjusting element towards stoichiometric at selected intervals to periodically establish the reference point setting. <IMAGE>
