Abstract: 1496638 Blasting WISSENSCHAFTLICHTECHNISCHER BETRIEB KERAMIK VE 20 Sept 1976 [22 Sept 1975] 38921/76 Heading B3D A process for polishing the surfaces of decorative coatings on ceramic vessels 2, such as cups, plates, pots, comprises mounting the vessels in holding devices 3, conveying the vessels to a processing zone, rotating the vessels in the cabin, and polishing the surfaces of the vessels while in the cabin by jets of powdered glass or powdered glass suspension, the vessels being cleaned and the powdered glass or suspension being collected and re-cycled. In apparatus for carrying out the method, the holding devices 3 for the vessels are carried by a turntable 1 to a cabin wherein they are set in rotation so that the vessels are polished by the powdered glass or a powdered glass suspension of 60% water and 40% solids projected normal to the surfaces of the vessels from nozzles 4. The glass is preferably in the form of glass beads having a size in the range 0À01 to 0À2 mm. and the vessels are rotated in the cabin at between 50 and 150 r.p.m. The powdered glass is softer than the surfaces of the ceramic vessels but harder than the decorative coating. The cabin is hermetically closed at its entrance and axis at which the articles are cleaned by water jets or spray. The powdered glass is collected in a vessel 6 and conveyed by a pump or pneumatic conveyer 7 to a container 8 connected to the nozzles. A suction removal device 9 and cyclone 10 are connected to the cabin.

Title: Improvements in or relating to measuring instruments
IPC: B07C5/07
Filed: 1959-11-19
Abstract: 912,640. Counting-apparatus; sorting by gauging. GAUTHIER G.m.b.H., ALFRED. Nov. 19, 1959 [Feb. 14, 1959], No. 39223/59. Classes 106 (1) and 106 (2). In an apparatus for checking at a plurality of sensing stations the linear dimensions of articles, separate counts are made at each station of the number of articles above and below a predetermined tolerance range, each counter being incapable of being actuated except when an article is present at the associated station. As described, articles are fed on to a circular conveyer 1 with which are associated eight sensing heads. One head 3 is shown, with an article 2 present, Fig. 1, and without an article present, Fig. 2. The head 3 has fixed but adjustable contacts 3a, 3b and a movable contact 3c mechanically connected to a sensing rod 3d. The number of articles having a particular dimension lower than a first value is counted on a counter Ia and the number of articles having the dimension greater than a second value is counted on a counter Ib. The sensing movement of the heads 3 is obtained from cams 12 on a control-shaft 11, each head 3 being fixed to a member 10 which is raised or lowered under the control of a pin 14 co-operating with the associated cam 12. The cam 12 is adapted to raise the member 10 and lower it so that the rod 3d comes into contact with an article 2. An adjustable abutment 31 is arranged so that if an article 2 is present, it comes into contact therewith, preventing further lowering of the member 10 and keeping a switch 7 closed. The switch 7 is in the cathode circuit of a double triode 4 in the actuating circuit for the counters Ia, Ib and ensures that only those counters Ia-VIIIa, or Ib-VIIIb at whose sensing station an article is situated, are actuated. To ensure that the counters are actuated only during an actual sensing operation, a further switch 16 is arranged in the counter circuits and is actuated by a cam 17 on the control-shaft 11. The articles on the conveyer 1 pass a plurality of sensing stations for different dimensions of the articles and at the final station (Fig. 3, not shown) there are provided two additional counters for counting the total number of articles passing through the apparatus and for counting " good " articles, the " good " article counter circuit having a switch opened when an article is outside predetermined tolerance limits, by a " storage device " which stores the measured dimensions. Modified arrangements for actuating the switch 7 are described (Figs. 4, 5, not shown). The articles leaving the conveyer can be sorted into " good " and " reject " categories by known sorting devices.

Title: Method of Producing Holograms
IPC: G03H1/20
Filed: 1968-08-16
Abstract: 1,180,539. Holography. AGFA-GEVAERT A.G. Aug.16, 1968 [Aug.18, 1967], No.39317/68. Heading G2C. Holograms which are free from undesirable line structures are produced by first forming a phase hologram and then copying it. The phase hologram may be obtained by bleaching a density hologram formed by the interference between an object beam and a reference beam of coherent light. In the copying process a spectral lamp, e.g. a mercury ore lamp with a filter for the green line, may be used. Alternatively, if the phase hologram has in line reference pencils incident in the optical axis an incandescent lamp may be used as the light source for copying. The copy holograms are themselves density holograms.

Patent GB-1165960-A (GB)
Title: Improvements in and relating to Dictating Machines
IPC: G11B15/18
Filed: 1967-08-31
Abstract: 1,165,960. Magnetic recording. SUDATLAS-WERKE G.m.b.H. 31 Aug., 1967 [3 Sept., 1966], No. 39834/67. Heading G5R. A dictating machine for exchangeable magnetic recording carriers comprises an arrangement which, after the machine is set in operation for dictation recording, or after a fresh recording carrier is introduced into the machine, causes the machine to run through a predetermined test interval in the playback position. Fig. 1 shows the relative movements and positions of the head T and recording track k for certain situations. Thus, when a recording carrier is introduced into the machine, head T is at point a of track k. When the machine is switched on, the carrier moves to the left so that in effect head T moves to the right through a test interval b (equivalent to 10 sees.) to a point c. If a recording is present on the carrier in the region b, then head T runs beyond point c, and the machine is not released into the recording mode until the end of the recording is reached. If no recording is present, head T in effect moves back from point c a distance d (equivalent to 5 sees.) to point e. At point e, the direction of movement is again reversed and the head in effect moves through interval f (equivalent to 10 sees.) to a point g. During this interval f, the test tone interval, a low frequency signal simulating speech is recorded on the carrier. At point g the machine is switched to the recording mode. The forward running during the test interval and the test tone interval can take place at an increased speed. In this case, the test interval may be longer, but in view of the increased speed there is no undesired loss of time. Since, during this test phase, an already-existing recording can with certainty be detected, the test tone recording can be dispensed with.

Title: Manufacture of tungsten-rhenium product
IPC: C22C27/04
Filed: 1965-09-30
Abstract: A method of making a W-Re product having a low ductile brittle transition temperature comprises producing a cast W-Re alloy article, deforming the article by at least 50% at at least 2500 DEG F. and further deforming the article at a temperature below the recrystallization temperature of the alloy.  The W, or W-base alloy containing at least 50% W, may include from 10% to 35% Re. Consumable electrodes, electron-beam melting or skull-casting &c. may be used to produce the molten, cast metal, and the alloy may be deformed by extruding, forging, rolling or swaging. In an example a W-25% Re cast ingot was machined to circular cross-section and its diameter reduced by more than 50% (e.g. 60-75%) by extrusion at 3700 DEG F.  The nose and tail of the extrusion were cropped and the surfaces cleaned by abrasion.  The extrusion was then pressed at 2400 DEG  F. with a reduction of at least 60%.  A specimen  of the sheet was then rolled at 1800 DEG F. to further reduce the gauge.  The reduced gauge may be further reduced by cold rolling.  Instead of rolling the extrusion, it could be reduced by swaging at 2000 DEG -2400 DEG F. The temperature of further deformation may be below room temperature, and a reduction of at least about 5% is needed to produce appreciable improvement in ductility.  Finally the product may be heat-treated and annealed.
