Title: Apparatus for Electrolytically Purifying or Softening Liquid
IPC: G01F1/28
Filed: 1979-12-03
Abstract: In apparatus comprising a liquid flow sensor e.g. 103 controlling the frequency of electrical pulses applied from a pulse generator across a first electrode formed by an elongate reservoir e.g. 110 for the liquid and electrode probe e.g. 106 extending into the liquid through a wall of the reservoir, the reservoir is enclosed in a housing 101 to one wall of which is secured a second housing 104 containing the generator access to the probe e.g. for cleaning is effected by disengaging the housings. This arrangement has the advantages of being compact, easy to install and requires little maintenance. In an embodiment the reservoir is sealed by blocks 111, 114 secured to tube 110 by probe 106. Piston 117 is mounted coaxially of probe 106 in a blind bore of block 111. The position of the piston varies with liquid flow and in turn varies the pulse frequency. <IMAGE>

Patent GB-2083624-A (GB)
Title: Measuring flow or movement
IPC: G01P5/24
Filed: 1980-09-04
Abstract: The invention relates to apparatus for measuring flow or movement in which irregularities in temperature and/or density are induced in moving material by an ultrasonic beam generated by a transducer 4. The ultrasonic beam is modulated by a wave form having good correlation properties so that e.g. a portion 5 of material flowing through a pipe 1 is affected to a varying degree as indicated by the density of shading in the drawing. The portion 5 is detected by detectors at 11 and 12 spaced distance d along the pipe 1 and the output of detector 11 is subjected to a delay at 17. The delayed output of 11 is correlated at 18 with the undelayed output of 12 and the delay 17 adjusted by manipulating the control 17A until the correlator output is a maximum. The delay value is then noted, this being a measurement of velocity. <IMAGE>

Title: Apparatus for destroying heat destructible records
IPC: A61B5/103
Filed: 1980-09-15
Abstract: Microfiche destruction apparatus includes a houseing (2) containing halogen lamps (16 & 18) and having a window (6) through which heat radiation from the lamps (16 & 18) is transmitted. A microfiche in an envelope having a higher melting point than the microfiche and coated with a layer of heat sealable material is placed in the window. A cover plate (8) has a glass window (10) which when the cover plate (8) is closed is aligned with the housing window (6). A clamping bar (4) clamps the open end portion of the envelope against the window (6). Heat applied to the envelope first seals the envelope along its clamped portion and then melts the microfiche inside the envelope. The destruction process can be observed through the window. In an alternative embodiment, with the cover plate normally closed the envelope is inserted between the cover plate and a support mesh through a narrow opening provided for the purpose. <IMAGE>

Patent GB-2095816-A (GB)
Title: Gas turbine combustor
IPC: F23R3/06
Filed: 1982-02-22
Abstract: A combustor (10) for a stationary combustor turbine is provided with a generally tubular sidewall (30) formed from a telescopic arrangement of sidewall ring members (44, 46, 48, 50). A corrugated spacer band (56, 58, 60, 62, 64, 66, 70) supports the upstream end portion (73) of each sidewall member (72) on the downstream end portion of the next inwardly located sidewall member (48) in the upstream direction. An annular coolant admission slot (38) is thus provided between the sidewall members with the corrugated spacer band located therein. The downstream end portion of each sidewall member (48) extends as an annular lip (78) projecting downstream from the downstream end of the corrugated band (70) to discourage mixing of the hot internal gases with the coolant air flowing as a film through the slot and along the inner sidewall surface. Thermal load is transmitted from the inner sidewall member (48) through the corrugated band (70) to the upstream end portion (73) of the outer sidewall member (72) where a slotted (77) wall structure enables outer wall deflection which in turn permits radial growth of the inner sidewall member (48) and its extended lip (78) substantially without disturbing the slot coolant flow. <IMAGE>

IPC: B41J15/02
Filed: 1982-06-11
Abstract: A transport roller for a record carrier in a printer, for example, an ink jet printer, is composed of at least two laterally adjoining, hollow, cylindrical roller sections (1). Each roller section is connected to a hub (5) by means of at least one carrier (4). The roller sections are adjacently arranged on a shaft (7) by way of the hub so that they am locked against rotation. An axial clamping device (10, 11, 12) ensures that the roller sections are pressed against one another. Furthermore, at a first lateral end (13) of each roller section there is provided a groove (8) which opens towards this first end and in which there is arranged an O-ring (9). The laterally open groove is closed by the roller section which adjoins this first lateral end. The roller end sections (2 and 3) may be constructed as so-called spiked rollers for the transport of a record carrier comprising a perforated edge. <IMAGE>

Title: A container and applicator for sterile liquid
Inventor: HESTHAVEN FINN
IPC: A61F9/00
Filed: 1982-12-02
Abstract: A container has a container body made of flexible material and at its outlet is equipped with a tubular outlet device (14) provided with a weakened zone (15). A contact member (19, 23, 22) with one or more strip-shaped contact surfaces (17) is arranged around the outlet device (14). The weakened zone (15) is located closer to the container body than the contact surfaces (17). Drainage openings (33) are defined in the contact member. To apply sterile liquid to an area to be treated (e.g. eyes), the outlet device (14) is broken at the weakened zone (15) to form an opening (34). The outlet device is directed towards the area to be treated and the container body is squeezed to eject the liquid. The contact member prevents direct contact between any part of the area being treated and the outlet device, and simultaneously the applied liquid is drained from the area through the drainage openings (33). This minimizes the risk of mechanical injury to the area being treated and minimizes the risk of contamination of the sterile liquid. <IMAGE>

Title: Load testing by water bags
Inventor: DAVIS PHILIP PETER
IPC: G01M99/00
Filed: 1983-01-19
Abstract: A water bag is lowered into the sea from a winch mounted on a structure which is to be tested for load-carrying capacity, the bag thus being filled with water. The water-filled bag is then lowered to a predetermined depth and raised by the winch at a predetermined speed, either to lift it slowly out of the sea until the full weight of the bag (which may be as much as 500 tonnes) is being applied, or to raise it through the sea at a predetermined speed such that a required magnitude of load is applied. A preferred open-topped water bag (10, 12) for carrying out the method is made of plastics-coated fabric supported at the top by a peripheral collar (18) which can be clamped by releasable clamping means (32, 34) to a circular yoke (20) which affords a large plurality of anchorage points (22) for suspension cables (23) which enable the bag to be attached to the winch. <IMAGE>

IPC: B65G17/00
Filed: 1983-03-17
Abstract: Apparatus for continuously distributing a succession of small pastry food products in rows across a moving conveyor comprises an endless conveyor including two chains (20,21) cross-connected by bars (25) on which can slide platforms (26). Each platform has a depending pin (26A) of a selected depth to engage one of a series of inclined shoulders (31,32,33,34) to deflect the platform laterally and smoothly into a selected one of a number of predetermined positions. When returning to the starting end the platforms are automatically shifted laterally into their original positions. Thus small pasties supplied on a conveyor in rows of three are automatically positioned in rows of 12 across the final conveyor. <IMAGE>
