Title: Improvements in or relating to colour television cameras
IPC: H04N9/097
Filed: 1969-01-28
Abstract: 1,207,282. Multi-colour optical systems. FUJI SHASHIN KOKI K.K. and NIPPON TELEVI HOSOMO K.K. Jan. 28, 1969 [Jan.30, 1968], No. 4712/69. Heading G2J. (Also in Division H4] In an optical arrangement for a colour television camera, the optical paths of the lights rays are so arranged that the image-forming surfaces of the pick-up tubes lie in the same plane and are close together, thereby giving a camera of small dimensions. As shown for a three-colour system, incident light from a subject for transmission is split into two paths by a partially reflecting mirror 17, one path being applied to a luminance pick-up tube 19 and the other path to a field lens 20. This latter path is then passed to a forward relay lens 23 via reflector 22, dichroic mirrors 25 and 26 being placed forwardly and rearwardly respectively of this arrangement to take off two component colours. The light path from dichroic mirror 25 is taken via reflectors 33 and 34 and relay lens 23<SP>1</SP> to its respective backward relay lens 36. The light path from dichroic mirror 26 is taken via reflector 35 to backward relay lens 37. From lenses 24, 36 and 37 the light is passed to the image-forming surfaces of respective pick-up tubes 27. Fig. 7 (not shown) illustrates an alternative arrangement using a three-colour system. Figs. 10 and 11 (not shown) illustrate modifications on Fig. 6 and (7) respectively for a four-colour system. Figs. 8 and 9 (not shown) illustrate alternative forms of the dichroic mirrors 25 and 26 in which colour shading is reduced by altering the angle through which the light path which is split off turns through.

Abstract: 380,354. Gauging- apparatus. AUTOMOTIVE MAINTENANCE MACHINERY CO., 816, West Washington Street, Chicago, U.S.A. Feb. 18, 1932, No. 4880. Convention date, April 30, 1931. [Class 106 (ii).] A device for gauging the alignment of connecting-rods of various sizes, comprises a support 16 secured to a plate 14 and readily adjustable to a large range of connecting-rod bearings sizes, and on this support the connecting-rod 15 is pivoted so that its other end can be brought against sets of gauging surfaces 42, 43 arranged at right-angles to one another on a slide 34 clamped at the desired distance on the plate 14. The adjustment on the support 16 comprises slides 20 which are adjustable radially by the spreading action of cones 23 and the contracting action of a spring 27, the cones being secured to a rod 22 which is moved axially by turning a screw cap 30. The gauge slide 34 has a U-shaped clamp base portion 35, and its surfaces 35a, 35b are clamped firmly against the adjacent faces of the plate 14 by turning an adjusting screw 37 and forcing a pin 39 into a V-groove 40 arranged as shown on the back of the plate 14. A spring 41 holds the pin yieldably seated in the plate groove. By sliding the member 34 off the end of the plate 14 and replacing it with the surfaces 42, 43 facing away from the support 16, the length range of the device is increased. Figs. 7, 8 and 9 show modified arrangements of the adjustment screws 53, 57, 64 and coacting surfaces 51, 60, 63c on the plate 14 for clamping the gauge member 34 in position. To gauge a piston and connecting-rod assembly, the member 34 is removed and the face of the plate 14 serves as a gauging surface for the piston.

Title: Method and apparatus for measuring the amount of coating material applied to a surface
IPC: G01B7/06
Filed: 1942-04-14
Abstract: 557,358. Determining dimensions of materials. BRUYNE, N. A. DE. April 14, 1942, No. 4920. [Class 37] The amount of glue or other coating material per unit area of coated surface is measured by applying at least one pair of electrodes to the coating and by means of a bridge circuit comparing an electrical characteristic of the coating material between the electrodes with the corresponding characteristic of a predetermined amount of the coating material. Apparatus for determining the thickness of a coating of glue on veneer in the manufacture of plywood by measuring the resistance of the coating comprises two cylindrical copper electrodes I.O., Fig. 2, spaced apart concentrically by insulating spacers S, the outer cylinder being attached to an insulating base. The lower ends af the cylinders are in one plane so that when in position on a glue-coated veneer they make uniform contact therewith. The upper ends of the cylinders are provided with terminals by which the coating between the cylinders is connected in one arm of a Wheatstone bridge. The comparison cell, Fig. 3, comprises a glass base G and an upright portion having a transverse bore H extending therethrough from end to end, a central vertical bore V passing into the transverse bore, and a smaller vertical bore V on each side of the bore V. The ends of the transverse bore H are closed by plugs P, the central vertical bore V enabling the transverse bore to be filled with glue. The bores v receive the ends of wire leads W forming electrodes which connect the coating material in the cell into an arm of the Wheatstone bridge. The bridge is supplied with an alternating current to avoid polarization effects, and is balanced by moving a sliding contact along a resistance provided with a scale indicating the amount of glue per unit area or the thickness of the layer. The various elements may be assembled in a common case to which numbers of pairs of electrodes as shown in Fig. 2 connected in parallel are fitted as feet. A valve amplifier may be inserted in the bridge circuit in place of the galvanometer and the null point determined by means of a small cathode-ray tube.

Abstract: 720,535. Cigarette hoppers. MOLINS, D. W., and MOLINS MACHINE CO., Ltd. Feb. 28, 1952 [March 1, 1951], No. 5014/51. Class 78 (1). In an apparatus (Fig. 2) for filling a hopper with cigarettes, an arm 10 carrying a tray of cigarettes rotates clockwise about pivot 11 so that the tray 12 assumes the position shown and deposits cigarettes in the hopper not shown, the collapsible guide 13 bending to permit the movement of the arm and guiding the cigarettes into the hopper and serving to eject from the tray as it returns any remaining cigarettes. The guide 13 is in two parts 13A and 13B, the part 13A being torsionally pivoted to part 13B which is torsionally pivoted to the frame. In Fig. 6 the guide (now numbered 5) has its two parts pivoted at 32; part 5A being linked by links 33, 35 to fixed pivot 36, and part 5B being pivoted at 31 and being connected to fixed pivot 24 by link 30, link 27 and link 23, there being a connection between extension 38 of guide 5 and link 27 by abuttal of pin 28 against the said extension so that downward movement of link 23 causes anticlockwise retractive rotation of guide 5 about pivot 31. The said downward movement of link 23 is caused by rotation of arm 10, the arm pivotally carrying cam 40 so that as the arm swings over the cam 40 engages and slides on the inside of roller 25 on link 23 and thus forces down said link 23 to retract the guide 5 until the cam has passed the roller, at which point the guide 5 is released and erects itself and remains there when the arm performs its return movement, recess 43 in cam 40 permitting said cam to slide past roller 25 on the outside thereof without depressing the latter Specification 637,850 is referred to.

Title: Process and apparatus for folding thermoplastic strips
IPC: B65H45/22
Filed: 1966-02-04
Abstract: 1,109,354. Thermoplastic films. FARBWERKE HOECHST A.G. 4 Feb., 1966 [5 Feb., 1965], No. 5014/66. Heading B5B. A process for folding thermoplastic strip is characterized in that the strip is folded by passing between a pair of vertical undriven rolls, separated by a distance less than the original width of the strip. The strip may be carried over a horizontal roll before entering the vertical rolls, and folding may be initiated by a notch in said horizontal roll. Specified thermoplastic materials include polyolefins, preferably high pressure polythenes, low-pressure polythenes or polypropylenes, as well as synthetic linear polyesters, especially polyethylene terephthalate and polyesters made from terephthalic acid and 1,4-dimethylol cyclohexane. In apparatus as shown in plan in Fig. 2, cut film strips 1, run over the horizontal rolls 2. where folding is initiated in grooves 5, and thence pass into the roll gap 3 between two vertical rolls 4. In order to fold as many strips as possible in a small space, several horizontal rolls may be arranged in tiers one above the other and fitted in front of the vertical rolls. Thus with three horizontal rolls in front of each two vertical rolls, three strips can be folded simultaneously. The bearings of the vertical rolls may be movable relative to one another to accommodate film of different widths. By altering the distance between the rolls, it is possible to vary the width and thickness of the folded film strip, so that differently shaped strips can be obtained with one apparatus.

Abstract: 685,276. Switch contacts. TELEFONAKTIEBOLAGET L. M. ERICSSON. March I, 1951 [March 14, 1950], No. 5018/51. Class 38 (v) [Also in Group XXII] In cross-bar and other switches in which it is desired to mount contact springs at suitably spaced intervals along an insulating support 15, a metal blank in the form of a band 11 is first cut out so as to produce a number of contact springs 12 arranged as closely as possible side by side with their ends still connected together as shown in the R.H. half of Fig. 2; the band 11 is then fed forward step by step at a certain speed to a fastening point 16 while the support 15, arranged beneath the band is fed forward step by step at a greater rate. At each pause in the step by step motion, the contact spring 12 at the point 16 is fastened to the support 15 bya rivetting process in which rivets 18 on the spring 12 are bent over the edges of the support 15, Fig. 6, The edges of the band 11 are simultaneously cut so as to free the spring 12 from adjacent springs. At the next forward step, the support 15 moves forward a greater distance than the band 11 so as to produce the desired spacing between springs 12, as shown at 22, 23. In a modification, the support 15 instead of being straight and moving rectilinearly may have another shape and move so that the contact springs are angularly inclined to each other.

Title: An improved arrangement for the telegraphic transmission of pictures or the like
IPC: H04N1/36
Filed: 1930-02-17
Abstract: 355,207. Copying telegraphy. SIEMENS & HALSKE AKT.-GES., Siemensstadt, Berlin. Feb. 17, 1930, No. 5274. Convention date, May 11, 1929. Void [Published under Sect. 91 of the Acts]. [Class 49 (iii).] In the transmission of pictures and the like by apparatus embodying a picture drum positively coupled to a motor driving a perforated interrupter disc inserted in the path of rays from a light source, the fineness of scanning is changed by a device arranged so that the desired signal frequency for the transimission line is still maintained. The picture, mounted on a drum 2, driven from a motor 1b, is scanned by a lamp 5 through one of two rings c, d of perforations in an interrupting disc 3, driven by a gearing train 17 .. 20. The shaft of the disc is mounted in a bearing member 4, rotatable on a shaft 16 between stops 7, 8, and carrying an arm 9 which in one position engages contact 10 to close the circuit of a relay 12. In the alternative positions of the relay armature, one of two tuning forks 13, 14 is coupled by a grid coil c or el and an anode coil f or /' to an oscillating valve 22 applying through a transformer 23 a driving frequency to a phonic wheel 1c. To change the fineness of scanning, the arm 9 is rocked out of contact with the member 10. The picture is scanned and the scanning beam interrupted through the inner ring d of perforations. At the same time the relay 12 introduces the fork with the higher frequency and the motor 1b is accelerated to drive the disc at a speed calculated to maintain the perforation transmission frequency practically unaltered, whilst the increased speed of the picture drum results in coarser scanning. The Specification states that the motor may be driven at different speeds from a single frequency by using a polereversible tone wheel or by the selection of one of a series of tone wheels with varying numbers of poles.
