Filed: 1968-12-23
Abstract: 1,213,879. Closing apparatus. B. VAN LEER N.V. 23 Dec., 1968 [28 Dec., 1967],No. 60930/68. Heading B8T. A closing apparatus for closing the filling hole of a drum 21 is characterized in that both the device 12 for locating the hole and the device 13 for inserting a plug are mounted to perform movements describable by cylindrical coordinates and are capable of being locked radially by a gripping device 7. A first frame 10 which houses the devices 13 and 15 and also a sealing device 14, is slidable on spindles 8 and 9 in a second frame 3. The filling drum is stopped under the core 15, the locating device is operated so that the cone 15 descends into the hole during which operation the cone 15 centralizes in the hole, thus moving the frames 10 and 3. The gripping device is then activated so as to secure a head 6 to a support 5. After the cone 15 is retracted, the screw driving device 13 is brought into position by an air cylinder (17) acting on frame 10, lowered, and retracted, followed by a similar operation for the sealing device 14. As soon as the device 14 returns to its original position, the gripping device 7 is de-activated. The supports 1 are vertically adjustable to accommodate different sizes of drum.

Title: Preset positioning device for pushbutton radio tuner
IPC: H04B1/06
Filed: 1978-06-13
Abstract: In a preset pushbutton tuner, each push rod actuator has an operating bar 38 pivoted thereon, which bar applies closing couples to a pair of scissors levers 35 which engage about and mutually align a preset memory pin 26 and a locator pin 28 carried by a tuning bar 27.

Title: Canned clam product
IPC: A23B4/02
Filed: 1978-10-03
Abstract: Canned clam meat food products suitable for human consumption are prepared from previously underutilized clam species, such as the ocean quahog, which develop a disagreeable odor, flavour and colour upon canning, by adding a treating agent selected from the group consisting of sodium bisulfite, sodium metabisulfite, and mixtures thereof, to the clam meat prior to in-can retorting. The treating agent can be added to clam meat in the can immediately prior to sealing and retorting, or during the boiling of a slurry of clam meat in water or expressed juices before the meat is placed in the can. In another embodiment, the edibility of clams such as the ocean quahog is improved by boiling a slurry of clam meat in water or expressed clam juices to drive off the substances which cause the development of disagreeable odor, flavour and colour upon canning.

Title: Platen for optical fingerpress image processing
IPC: A61B5/117
Filed: 1978-10-25
Abstract: A platen for optical fingerpress image processing consists of a glass base 32 against one face of which collimated light is directed, with a layer 34 of transparent compressible resilient epoxy on the other face, which in turn carrier a thin silver deposit protected by a lacquer 38. When a finger is applied through the lacquer 38 and the silver layer, the ridges Fr of the finger press distort the adjacent part of the epoxy 34 sufficiently to scatter incident light, but light under the valleys Fv of the fingerpress is reflected because the corresponding portions of the epoxy layer 34 are undistorted. The pattern of light reflected from the glass base 32 for processing, as by comparison with a reference fingerpress image, has very good contrast between areas corresponding to fingerpress ridges Fr and areas corresponding to valleys Fv. <IMAGE>

The present invention produces the comminuted charge by comminuting alumina-containing raw material in a soda-containing solution so that the fraction of comminuted material of size greater than 0.08 mm amounts to over 12 percent by weight; mixing the comminuted alumina-containing material with carbonate-containing raw material and a soda-containing solution to ensure a molecular ratio of alkali metal oxide to alumina of at least 1 to 1 and a molecular ratio of calcium oxide to silica of 2 +/- 0.03 to 1; and comminuting the charge to obtain a fraction of size greater than 0.08 mm in an amount of 2 to 15 percent by weight.
Patent GB-2032105-A (GB)
Title: Improved multifold cross- correlation for borehole signals
IPC: G01V1/36
Filed: 1979-09-07
Abstract: Methods and apparatus are described for improving the cross correlation of three or more signals (e.g. acoustic logging signals) derived in an investigation of a borehole. The technique involves the testing of signs of samples employed in forming a cross-product during a cross- correlation. Sign conditions representative of a good match are so recognized and the resulting cross- product modified (by weighting) if needed for constructive contribution to the cross-correlation. Sign conditions indicative of a lack of correspondence between samples can also be detected so that cross- products from such samples can be prevented from adding to correlation peaks when an even number of negative samples are present.

Title: Mechanical-electrical pressure transducer
IPC: G01L9/14
Filed: 1979-09-27
Abstract: A Hall-effect component (10) is disposed on a diaphragm of an aneroid box and is located between two permanent magnets (7, 9) whose end faces of like polarity are located opposite one another, the distance between the Hall- effect component and one or both of the magnets being varied by means of the diaphragm (17) in dependence upon the pressure to be measured. The transducer is for measuring the vacuum in the intake manifold of an i.c. engine. The magnets may be of cobalt and samarium. Adjusting the compensating magnet 9 allows the Hall-effect component to be disposed at a region of zero magnetic induction. Subsequently a linear relation between pressure acting on the diaphragm and transducer output voltage may be achieved. <IMAGE>

Title: Diffracted X-ray beam monochromator
IPC: G01N23/00
Filed: 1980-01-03
Abstract: An X-ray beam monochromator comprises a monochromator crystal mounted in a housing 16 supported on posts 7 fixed to a base plate 1,and provided with an output slit and detector coupler 17. A further support 5 projects into the housing 16 and is provided with a channel into which a Soller collimator plate 6 can be inserted and releasably held by a detent mechanism. The crystal may be graphite, which provides a high diffraction efficiency compared with e.g. LiF or quartz, but without input collimation cannot provide sufficient resolution to reject closely adjacent source frequencies e.g. Cu Ka2 when using Cu Ka1. The presence of a collimator, however, reduces the overall sensitivity and the arrangement enables the collimator to be readily located or removed depending on whether a good beam profile or good sensitivity is required. <IMAGE>
