Abstract: 435,812. Tempering glass. PILKING- TON BROS., Ltd., Tower Building, Water Street, Liverpool, and WILSON, J., 23, Meadow Hill Road, King's Norton, Birmingham. March 29, 1934, No. 9800. [Class 56] A process for tempering glass consists in heating and cooling the glass indirectly through the medium of a metal in liquid form. In tempering a sheet of glass, for example, the sheet 16, is placed in a shallow metal box 4, and is kept in a central position in the box by means of metallic supports 11 12, 15. The box is filled with molten metal, preferably a bismuth alloy having a low melting-point, and is put into a furnace. When the glass has been heated to the desired temperature, the box is removed from the furnace and cooled rapidly, by water sprays or by dipping it into water. The cooling is stopped before the metal solidifies to allow the glass sheet to be removed. The glass may be covered with a layer of protective material before inserting it in the metal.

Title: Improvements relating to the generation of colour television signals
Inventor: HUNTLEY KEITH GORDON
IPC: H04N11/00
Filed: 1954-04-03
Abstract: 771,536. Television. ELECTRIC & MUSICAL INDUSTRIES, Ltd. March 24, 1955 [April 3, 1954], No. 9840/54. Class 40 (3). In an arrangement for generating colour television signals employing a plurality of pickup devices responsive, respectively, to different component colours of the object to be televised and the light from which is selectively distributed to the different channels by optical filter means which allows overlap of the different spectral bands peculiar to each pick-up device, the filter means is such that the ratio of the response of a selected pick-up device to that of another pick-up device is substantially greater than the ratio of the intensities of the corresponding primary colours, the selected channel being such that the effect of noise is reduced when the light intensity is low. The invention is described in connection with a colour television system employing the principles of the N.T.S.C. system although the arrangement is applicable to other systems and in particular to the generation of signals by scanning films since shortage of light is frequently a problem in such arrangements. Fig. 1 shows a conventional transmission system employing the principles of the N.T.S.C. system in which the arrangement according to the invention is realized by employing an optical filter system 4 which allows the selected pick-up device, in this case the device Y which provides the luminance signal (since the eye is more tolerant to noise distortions in colour than in brightness) to receive five times the amount of light which the devices X and Z receive and to compensate for the effect of this additional light the gains of the amplifiers 5, 6 and 7 are adjusted to restore equality of signals in the three channels, i.e. equal signals for white light. The filter system 4 may be comprised of dichroics 16 and 17 (Figs. 5 and 6) the reflectances and transmittances of which are chosen to produce the desired result. If the sensitivity response of the pick-up devices (cathode-ray tubes) departs from a desired characteristic compensation may be effected by means of an overall filter between the object and the filter system 4.

Title: Improved variable pitch propeller assembly
IPC: B64C11/30
Filed: 1958-03-28
Abstract: 816,289. Variable pitch propellers. GENERAL MOTORS CORPORATION. March 28, 1958 [April 2, 1957], No. 9970/58. Class 114. ' A propeller assembly has a hub 10 carrying variable pitch blades 12 movable to a feathered position, a spinner 17 with an air inlet 21 and an air outlet and air shut off means within the spinner operatively connected with the blades to prevent air flow through the spinner between the inlet and outlet with the blades feathered. Air flows from inlet 21 across a heat exchange reservoir 14 to cool the hydraulic fluid used to actuate the pitch adjusting motors, is discharged through openings 18 into the interior of the spinner, flows through openings 30 (Figs. 2 and 3) in a member 31 housed within a spinner bulkhead 22 and thence (see arrows in Fig. 1) via openings 28 and 91 to atmosphere. A bevel gear 37, Fig. 2, which coordinates the pitch adjusting movement of all the blades by meshing with gears 36 thereon is splined on a sleeve 40 to which is secured an annulus 42. As shown in Fig. 3 the rotatable annulus 42 has toothed segments 43, 44 and 45. The segment 43 is engageable with a feedback pinion assembly 46 similar to that in Specification 724,855. Rotation of the blades to increase pitch rotates sleeve 40 and annulus 42, and as feathered position is approached toothed segments 44 and 45 engage pinion assemblies 53 and 54 so that sector gears 56 and 59 thereon in engagement with a gear segment 64 on an element 65 rotate the latter whereby shutters 66 on the element 65 are moved to close the openings 30. In the arrangement shown in Fig. 3 the openings remain open between the maximum negative thrust angle and a positive 60 degrees. At the latter angle movement is imported to the shutter element 65 so that the air flow path through the openings 30 is automatically closed when the blades are at an angle between 80 degrees and fully feathered. In another embodiment the movement of the shutter element is continuous. The rotatable annulus 42 is engageable with a non-rotatable annulus 75, Fig. 2, to constitute a mechanical low pitch stop operable in the manner described in Specification 798,372. A nonrotatable pitch lock member 85 has teeth 86 engageable with teeth 87 on the master gear 37 and a piston surface 88 which can be subjected to hydraulic pressure to prevent engagement of the locking members. Specification 810,453 also is referred to.

Patent HU-T48954-A (HU)
Title: Retainer
Inventor: FISCHER ARTUR
IPC: F16B13/06
Filed: 1988-04-12
Abstract: Fasteners, which are used for fastening high loads, are braced in the hole (1) by means of a spreading body (8) which is moved in a spreading sleeve (9). If the fastener is subject to high instantaneous stresses, for example as the result of earthquakes, there is the risk that the fastener may break out of the hole (1). In order to ensure that the fastener continues to maintain its retaining function, even after the occurrence of high excess stresses, the spreading sleeve (9) is operated by means of a force store, which is preferably designed as a screw spring (10). The tensile force exerted by the fastened object on the fastener is transmitted via this force store to the spreading body (8). In the event of shock stresses, the force store acts as an elastic spring element which absorbs hard shocks elastically. The fastener is thus particularly suitable for use in earthquake-hazard regions or in areas where enhanced safety requirements apply. <IMAGE>

Title: Process for treating rolled steel to improve its corrosion resistance
Inventor: AICHER MAX
IPC: B21C43/04
Filed: 1988-08-18
Abstract: To apply a coating of a non-ferrous metal such as, for example, zinc to the surface of rolled steel to increase the corrosion resistance, it is proposed to descale the rolled steel continuously downstream of the rolling step from the rolling pass by applying pressurised water and, immediately after descaling and while preventing a renewed formation of scale, to cool it by means of water rapidly to a temperature suitable for hot application of the coating and finally to apply the coating. One of the advantages of the invention is that, both for descaling and for preventing the renewed formation of scale and for simultaneous cooling, only a single medium, namely water, is used, and the cooling can be controlled in such a way that the rolling pass can be exploited in an optimised manner for the coating. The result is that all process steps or treatment processes can proceed as a continuous extension of the rolling step, i.e. at rolling speed, so that the finished coated end product leaves the production line analogously to a normal, not aftertreated rolled product.

Title: Straight line recognizer
Inventor: KONISHI KUNIAKI
IPC: G06T3/00
Filed: 1984-01-07
Abstract: PURPOSE:To attain the straight line recognition at a high speed by obtaining the distance up to a straight line connecting the start and end points of two vectors which are continuous to each other and show a linear diagram, integrating them and deciding as a straight line when said distance is smaller than a fixed allowable range. CONSTITUTION:A linear diagram is read by a dot train and stored to a dot train data memory 10. This dot train is converted into a vector train after the fixed allowance is set by a vector converting device 12. A straight line/curved line data separator 14 separates the straight line candidates from the curved line candidates to supply them to a straight line recognizer 16 and a curved line recognizer 18. The recognizer 16 performs the mere vector integrating process and therefore can attain a high-speed operation. The recognizer 16 includes an inter-vector cosine arithmetic circuit and obtains an angle between two continuous vectors. The cosine value is supplied to a straight line deciding circuit and compared with the threshold value set previously to decide the straight line. In case the cosine value is smaller than the threshold value, the two vectors are integrated into a straight line.
