Title: Apparatus and method for the time base of television signals

Filed: 1975-05-22
Abstract: 1494845 Television systems EASTMAN TECHNOLOGY Inc 22 May 1975 [10 June 1974] 22244/75 Heading H4F To compensate for time base variations in the signal from a video tape recorder the signal is clocked into a shift register store at a first stable rate and is clocked out of the store at a second stable rate which is greater than the first and which is an integral multiple of the nominal line frequency. In the embodiment shown, Fig. 2, the video signal from the recorder 7 passes to three one-line shift register stores 4<SP>1</SP>, 5<SP>1</SP>, 6<SP>1</SP> which may each be a 256 stage charge-coupled device. Each store is large enough to store a complete video line that has been time-stretched by a predetermined maximum amount, e:g. due to flutter. Successive lines are read into successive stores under the control of clock pulses at the first stable rate from a generator 11, pulses being gated to each store in turn by logic circuitry, e.g. 16, 18, 22, 25 for store 4', controlled by a 3-bit counter 12 incremented by line sync pulses separated (8) from the video signal. The line sync pulses also pass via a half line delay 44 to a phase lock loop comprising low pass filter 46 and oscillator 48 which provides pulses at the second and greater stable rate. The pulses from oscillator 48 read out each store in turn to output 82 under the control of a 3-bit counter 54 incremented at a stable line sync rate by pulses derived (50) from the oscillator.

Title: Improvements in relief maps and process of producing same
IPC: B44C3/04
Filed: 1919-09-12
Abstract: 152,842. Marks, E. C. R., (Newbold, F.). Sept. 12, 1919. Drawings to Specification. Maps.-A method of producing relief maps consists in forming a wax or like model by carving &c., making a metal die and counter-die from the model, moulding a matrix between the dies, transferring the written and drawn features of the map to the matrix, flattening the matrix, making reproductions from the flattened matrix, and moulding the reproductions to the relief form between the dies. A tracing of a flat topographical map, having the contours marked on it is first made, and this is transferred to a block of wax, which is modelled to shape by carving each contour to its true depth and removing the surplus material. From this model a plaster cast and counter mould are prepared, and from these a metal die and counter-die are cast. A matrix of substantially non-elastic material such as paper and thin blotting paper pasted together is placed between the dies in a steam press while the paste is still wet, the resulting product being hard and stiff and conforming to the shape of the dies. When the matrix is thoroughly dry and hard, it is placed on the metal die, and the lines and markings of the original map are transferred to it by means of a pantograph or by photography. The matrix is now removed, moistened, and pressed out flat, when it shows the features distorted as compared with the original map. The flat distorted map on the matrix is transferred or reproduced by photo-lithography. The reproductions are mounted on several sheets of backing-material similar to that employed in making the original matrix, and while still wet are pressed oetween the dies to the relief form.

Abstract: 706,609. Fork lift trucks. YALE & TOWNE MANUFACTURING CO. Sept. 8, 1952, No. 22496/52. Class 78 (3) [Also in Group XXXIV] In a pedestrian controlled fork lift truck the fork and guide assembly is tilted rearwardly by raising the complete chassis on a pair of pivoted arms 26 which carry the traction wheels 35. The arms 26 which are connected together by a bar 27 are journalled on the half shaft 39 extending from a differential gear unit (not shown), and a hydraulic thrustor 71 pivots the arms to extend or retract the wheels 35 relative to truck chassis. Each half shaft is splined to a sprocket 40 connected, by a chain 43, to a sprocket 34 rotatable with the associated wheel. The rotatable differential housing is secured to a driving sprocket 46 which is connected by a chain 45 to a sprocket 44 on the traction motor shaft; thus the drive to the wheels 35 is maintained in all positions of the arms 26. Switches 16 on the steering handle 14 control the traction motor, and motors driving the hydraulic pumps (not shown) which actuate the thrustor 71 and other thrustors (not shown) which effect movement of the guides 21 on the guides 20 and movement of the fork 23 on the guides 21. A valve 19 operated by a handle 18 controls the flow of fluid to the thrustor 71. The traction wheels are braked (see Group XXXIV) by a pair of brake shoes (not shown) which are arranged around the rotatable differential housing and are normally spring urged out of contact therewith, but which, when handle 14 is raised and a lever 58 is depressed, are engaged with the housing by a linkwork (not shown).

Mercaptonaphthothiazole, mercaptobenzothiazole and phenyl, methyl, amino and chlorine substituted mercaptobenzothiazoles may be used, with cyclic amines such as cyclohexylamine, hexahydrobenzylamine or benzylamine. The accelerators may be employed in conjunction with basic nitrogen containing accelerators such as diphenyl guanidine, diphenylguanidine phthalate, triphenyl guanidine or di-ortho-tolyl-guanidine.

A latch for refrigerating cabinets, chests and the like, has a two-armed forked latch bolt 7, is rocked by means of a connecting element 9 which is pivoted to it, carries a power storagespring 13 rocks about a fixed pivot 15 and is in engagement with a two-armed operating lever 2, the shorter arm of the lever 2 bears against the connecting element and acts as a push bar in such manner that when the operating lever is operated, the connecting element is displaced about its fixed pivot in opposition to the action of the spring so that the pivot 10 between the connecting element and the latch bolt is moved from an upper position beyond dead centre (fastening position) to a lower position beyond dead centre (unfastening position). The latch bolt is bifurcated and is pivoted by means of a pin 6 to a U-shaped sheet metal part 5 attached to a base plate 1. The connecting element 9 is of frame-like construction to house the spring 13. The spring 13 engages the connecting element at one end and its other end engages a slide 14 which is slidably connected to the element 9. The element 9 is mounted on the pivot 15 by means of a slot 16 and it is engaged by a rod 11 carried by the lever 2. The lever 2 is of U-shape and it is pivoted to the base-plate 1 by pins 3. When the lever 2 is pulled the rod 11 moves the connecting element which in turn rocks the latch bolt so that it becomes disengaged from a keeper 8. One limb of the actuating lever can be provided with a cylinder lock 17 the bolt of which engages a hole in a flange of the base-plate to prevent movement of the actuating lever.

A planetary change-speed gear for a heavy vehicle, providing at least three reduced, direct-drive and two reverse ratios, comprises four sun-ring trains 16, 18, 20, 22, of which the first, 16, of higher torque capacity than the others, is used alone for first ratio, and has its reaction ring-gear accelerated in stages by compounding with the other trains in higher ratios. A first input clutch 34 is engaged in all forward ratios to drive the connected suns of the first and second trains 16, 18. In first (4À00), a first brake 24 holds the ring of the first train 16 which acts alone. In second (2À21) the first ring is driven forwards by the second train 18 alone, by releasing the brake 24 and holding the ring of the second train 18 by a second brake 26. In third (1À75) brake 26 is released and a third brake 28 applied to hold the carrier of the fourth train 22, which compounds with the fluid train 20 to accelerate the ring of the first train 16. In fourth (1À33) the brake 28 is released and a fourth brake 30 applied to hold the sun of the third train 20, which acts alone to accelerate further the ring of the first train 16. For fifth the brake 30 is released and a second input clutch 32 engaged to drive the connected third and fourth suns, locking the gear for direct-drive. The first reverse (-2À62) uses clutch 32 with brake 26, the first three trains 16, 18, 20 compounding. The second (-8À00) uses clutch 32 with brake 24, the second train 18 reversing, the first, 16, reducing.
