Title: Plate clamping mechanism for rotary printing machines
IPC: B41F27/10
Filed: 1935-02-01
Abstract: 447,303. Printing-machines. HOE & CO., Ltd., R., 109, Borough Road, London.- (Hoe & Co., Inc., R. ; 138th Street, New York, U.S.A.) Feb. 1, 1935, No. 3385. [Class 100 (ii)] Printing.-surfaces.-Mechanism for actuating the plate clamps on a printing-cylinder comprises a member 42, Figs. 2, 7, and 9, adapted to be rocked about an axis 43 parallel to the axis of the cylinder by means of a tool 46, with which a retaining member co-operates to resist withdrawal of the tool except when the member 42 is in plate-clamping position, the removal of the tool causing a locking member to engage the member 42 and hold it against movement from plate-clamping position. The tool-retaining member consists of a pin 55 slidably mounted in the member 42 and engaging a recess 70 in the side of the tool. When the member 42 is in the plate-clamping position, as shown, the head of the pin 55 lies opposite to a recess 68 in a member 37 secured to the cylinder, so that the tool can be removed. When the tool is thus removed, a spring pin 65 mounted in the member 37 enters a hole 59 in the member 42 to lock it against movement. At the same time a pin 56 within the hole 59 is moved into the tool socket in the member 42 so that when the tool is reinserted the pin 65 is moved out of locking position. In this form, when the member 42 is moved out of clamping position, the pin 55 is positively moved into the recess 70 in the tool 45 by the engagement of its head with the inclined wall 71 of the recess 68, but in a modification, the pin is pressed' into retaining position by a spring. In this modification also a roller or projection on the tool is provided and adapted, if the tool is inadvertently left in the member 42 when the machine is started, to engage a fixed cam and cause ejection of the tool and warning to the operator. In both forms of the invention, the movement of the member 42 is communicated to the clamps 17 by means of an arcuate block 36 moved circumferentially of the cylinder by the member 42 and carrying a roller 33 engaging a cam groove 20 in a block 25 having a forked portion 28 engaging a screw 19 on which the clamp is threaded. The movements of the block 25 are communicated to the screw 19 in one direction through a spring 31 and collar 32 and in the other direction by engagement with the head 24 of the screw.

Abstract: 1,124,122. Photographic type-composing. VYZKUMNY USTAV POLYGRAFICKY. 26 Jan., 1966 [29 Jan., 1965], No. 3467/66. Heading B6W. A disc 3, Fig. 1, provided with a plurality of character matrices 4 and trapezoidal shaped marks 7, each radial line on which there is a matrix. having thereon two matrices and two marks, each matrix having a corresponding mark the width of which corresponds to the character width in a main optional system 1, light is directed by two semi-transparent prisms 6 to both matrices in the radial line aligned with the system, and thence to photosensitive material 15. The disc is stopped in the desired position for each character by a detent 8. An adjustable aperture 19 is adjusted to expose only that one of the pair of matrices required, and the corresponding mark. In an auxiliary optical system 2, light is similarly ducted through a lens 10, selected mark prism 23, and modulating screen 12 having vertical opaque stripes to a movable receptor 13, which for each character is moved across the stripes so as to transmit a number of impulses to a motor 17 for feeding the member 15 stepwise, the number of impulses depending on the number of stripes within the image of the mask, and therefor on the width of the mask. The system 1 can be adjusted for point size, which automatically adjusts the receptor 13 along the stripes so as to vary the effective width of the mask because of its trapezoidal shape. An adjustable aperture 18 can further vary the number of impulses, as for spacing. In another form, Fig. 3 the masks are rectangular slots 20 of various lengths and the stripes on the screen 21 are fan-shaped; whereby the number of impulses for a given mask depends on the position of the receptor 22 along the stripes.

Abstract: 1,013,986. Docks for loading and unloading vehicles. G. HUNTER (LONDON) Ltd. May 13, 1963 [Jan. 30, 1963], No. 3879/63. Heading B8E. A dock leveller comprises a platform 2 pivoted to the dock 4 at 6 and partially counterweighted by a lever 64 and weight 68 as described in Specification 948,657. Means are provided so that by contact with buffers a vehicle causes the platform to be raised and then released to drop into a loading position in contact with the vehicle. A trolley 22 runs on rollers 24 carried by rails 26 and mounts resiliently faced buffer plates 32. The trolley is biased: to the outward position shown by springs 54. As a vehicle contacts the buffers 32 it. forces the trolley rearwards so that a strut 36 first raises the platform by contact with a guide plate 40 until a roller 50 of a lever 44 can contact a dwell cam 42 to support the platform in its raised position. During this movement support member bore 14 remain extended in their operative position so that they mould engage recesses 16 in the limbs 12 of the frame to prevent downward movement of the platform if a sudden load was applied. As the innermost position of the trolley is approached a cam-plate 52 engages arms 18 to withdraw the bars 14 to an inoperative position so that the platform can drop under gravity into contact with the vehicle when the roller 50 passes beyond the dwell cam 42. The springs 54 return the trolley when the vehicle withdraws. Specification 948,657 is referred to.

Title: Improvements in or relating to treatment of steels
Inventor: IRANI JAMSHED
Filed: 1965-01-28
Abstract: Alloy steels containing 0.08 to 0.3% of carbon and 2 to 5% of vanadium and having an Ac3 point below 650 DEG  C. are solution treated at such a temperature e.g. 1200 DEG  C. that all the vanadium carbide is taken into solution and are then quenched, preferably in oil.  The steel is then aged at 650 DEG -850 DEG  C. e.g. for 5 to 50 hours, to precipitate vanadium carbide in association with stacking faults, after which it is quenched to below the Mf temperature. Preferably the steel is of section having one dimension not more than 1", or in the case of tube a wall thickness not exceeding 1/2" , is then reheated rapidly to above the Ac3 temperature for a time just sufficient to complete transformation to austenite and is then rapidly quenched to below the Mf point.  The steel may be worked e.g. to 10% deformation between the first quench and the ageing treatment, or may be worked at the end of the ageing treatment under such conditions of time and/or temperature that no transformation to bainite or pearlite occurs.  Suitable steels for the application of the process are those containing, in percentage by weight  .C.0.08 - 0.3 .V.2 - 5 .Ni.0 - 10 .Mn.0 - 5 .Fe.balance  with chromium being optionally present in the range 3 to 8%

Title: Line deflection linearity correction
IPC: H04N3/23
Filed: 1975-01-29
Abstract: 1500831 Line deflection circuit PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 29 Jan 1975 [1 Feb 1974] 3905/75 Heading H3P The invention relates to a circuit in a television display apparatus for correcting the horizontal linearity of the deflection current flowing in a line deflection coil Ly which forms part of a series arrangement including a correction inductor L having a premagnetized core, the series arrangement, having inherent circuit resistance, and a substantially constant voltage E across it during the deflection interval. According to the invention the series arrangement includes an additional circuit means across which a voltage is present during the deflection interval having an approximately linear function of time and of a form and polarity to aid the linearity of a display on a display tube in the apparatus. As shown the additional means is a set of resistors R 1 , R 2  selectable by the switch S. The correction inductor would be adjusted when the inserted resistance has half the maximum possible value, and in the absence of any horizontal centring deviation. Thus a voltage can be removed or added, by placing the switch S in the various positions, and thus providing a compensation which has an effect throughout the deflection interval (Fig. 4). The correction inductor L provides, as usual, a correction which is large at the beginning of the interval but falls to a negligible effect at the end (Fig. 3, not shown). Instead of the resistors R 1 , R 2 , a line-frequency sawtoothed-shaped voltage source (not shown) can be used in series with the correction inductor L.
