IPC: G02B7/08
Filed: 1968-11-20
Abstract: 1,250,619. Photographic type-composing. MONOTYPE CORP. Ltd. 19 Nov., 1969 [20 Nov., 1968], No. 55091/68. Heading B6W. Light passes through characters selected in turn on a matrix plate 2, through a lens 12 for point-size adjustment, along a path 3a to two mirrors 4 and thence along a parallel path 3b to a character-spacing mirror 6 and on to a film 8. When the lens 12 is moved to alter the magnification, the mirrors 4 are moved a related distance to maintain constant the length of the optical path between the lens and the film. As the mirror 6 is moved for character-spacing, the mirrors 4 are moved half the distance, again to maintain the path length constant. A steel tape 14 is passed round a pulley 10 rotatable by a stepping mirror, a stationary pulley 16, and pulleys 18, 22 secured to a rod 19 to be movable as a unit, and is attached at each end 14a, 14b to a rod 20 secured to a connecting member 66. The mirror 6 is attached to the tape by a mounting member 24 and the mirrors 4 to the rod 19. When the pulley 10 is stopped for character-spacing, with the rod 20 stationary the tape is moved to move the mirror 6 and to move the pulleys 18, 22, rod 19 and mirrors 4 at half the speed. The lens is supported on a member 12a connected to a member 31 by a rod 30, and the member 66 is secured to a member 62, the members 12a, 31, 62 being guided for horizontal movement. A lever 50 is pivoted at one end to the member 31 and is also pivoted to the member 62 and to a member 42 guided for vertical movement, the lever being slidable with respect to the members 42, 62. The members 31, 42 are linked by a bell-crank 36. Movement of the member 31 by a second stepping motor is thus transmitted to the member 42 to alter the position of the pivot of the lever 50, while at the same time moving the lever 50 about its pivot in the member 42 so as to move the member 62. In operation, the second stepping motor moves the lens 12 and member 31 to an extreme left-hand position, moving the member 42 upwards until it contacts a switch which reverses the motor. On its subsequent downward movement, the member 42 contacts a series of switches until it contacts the one which has been activated by a point-size signal on an input tape, when the motor stops with the lens and the mirrors 4 in the correct position. The movement of the member 62 is transmitted to the mirrors 4 through the member 66, the rod 20, the pulleys 18, 22 and the rod 19, the pulley 10 remaining stationary and the rod 19 moving half the distance of the rod 20. The members 31, 62 are spaced apart vertically by the focal length of the lens.

Abstract: 1296026 Magnetic data storage SUBSCRIPTION TELEVISION Inc 2 April 1970 [7 April 1969] 15584/70 Heading G4C A magnetic store has at least one storage track on which is recorded a synchronizing signal followed by data signals. The form of recording is such that there is a bit transition at the beginning of each bit, each 1-bit also having a mid-bit transition. The bit duration of the sync. signal is longer than that of the bits forming the data signal. Buffers in the read-out circuitry compensate for skew. As described, n-bit signals are recorded in parallel-bit form on a magnetic tape. The data bits in each track are preceded by a sync. signal consisting of a number of 1-bits each 1.5 times the duration of a data bit. Fig. 5 (line 2) shows the first few signals on one track. The signals read from each track are limited (line 3) and passed to EXCL-NOR gates 90, 91, Fig. 4, and to 1-bit delay 88 whose output (line 4) passes to gate 90 and to a ¢-bit delay 92 whose output (line 5) feeds gate 91 and clock 95. The output (line 6) of gate 90 is an NRZ binary signal corresponding to the recorded data except during the sync. signal when -bit pulses 251 occur. These pulses are removed by filter 93 (line 7). Similarly, the output (line 8) of gate 91 is filtered (line 9). The filters feed a circuit 100 (Fig. 6, not shown) which detects when filter 93 gives a value 0 and filter 94 gives a value 1 both for a certain duration, the circuit then generating a Start signal at the first occurrence of a 1-bit thereafter. The Start signal clears an address circuit which determines the position in which a bit read from the track is to be placed in a buffer store unique to that track. The Start signal also clears the buffer. The clock circuit 95 derives bit-rate clock signals from the output of delay 92, the clock signals controlling the input address circuit and the input shifting of the buffer. One of the recorded tracks is arbitrarily selected as a master track and that track's derived clock signal controls the output address circuits associated with each buffer and controls the output shifting of each buffer. The speeds at which bits are stored in and withdrawn from the master track's buffer are compared to control the buffers' read out to such a rate that the master track's buffer remains about half full. At the end of the data signals an end-of-message sync. signal is read from each track, followed by a Stop signal. Circuitry detecting these signals ensures that only useful data is read from the buffers.

Abstract: 1296220 Overload protective systems T MOORE 13 Dec 1969 60896/69 Heading H2K An overload-responsive arrangement has a first thermal switch to effect the operation of an indicator at a first excess current level and a second thermal switch to effect the operation of a further indicator and the interruption of the supply to a protected device, e.g. a motor, at a higher current level. In the arrangement shown, a green lamp 17 is lit when the motor is not overloaded. When the first current level is reached, a bimetallic element 22 in series with the motor closes contacts 24, 25 to light an amber lamp 16. When the higher current level is reached, bimetallic elements 26, 27 move apart to open contacts 30 and interrupt the current to the motor. A red lamp 15 connected across the elements 26, 27 is now lit with the result that the voltage across the motor is not sufficient to maintain the lamps 16, 17 lit. The arrangement may be disposed in a housing with a socket outlet and the housing may have plug pins so that it may be used as an adapter.

Title: Controlling the production of textile webs especially carded webs

Filed: 1971-12-30
Abstract: 1337020 Detecting defects in webs WIRA 30 Dec 1972 60663/71 Heading G1A [Also in Division G3] In a device for use in controlling the production of a textile web W light from a source 100 is collimated by a lens 104, passed through the web W, and focused via a rotatable optical wedge 108, a rotating disc shutter 114, and a half-silvered mirror 110 on to a photo-cell 102, which also receives light from the light source 100 via a light guide 112, a shutter 114 and the half-silvered mirror 110. The output of the photo-cell is processed in a similar fashion to that disclosed in Specification 734078 to provide a measurement of the density or to effect changing of the controls of the web producing machine. The rotating shutter Fig.2, (not shown) is preferably in the form of a disc containing two apertures positioned so that the photo-cell 102 alternately receives light passing through the web W and light passing through the light guide 112. The shutter 114 may also serve to control the switching of the electrical output at a switch 128 by providing two further slots in the shutter positioned to interrupt the paths of light travelling from two further light sources to two further respective photo-electric detectors whose outputs activate the switch 128. In a modification Fig.3, (not shown) the source 100 is located in a rotating drum which is transparent only over an arcuate section (132). The section thereby allows light to travel alternately via the web W and via the light guide 112. In a further modification, Fig.4, (not shown) the shutter 114 and the half-silvered mirror are replaced by a rotatable disc 200 of transparent material and having diagonally opposite edge regions of which one is part-cylindrical 202 and the other is bevelled and light-reflective. Thus as is shown in Fig.4 (not shown) in one position of the disc 200 light passing through the web reaches the photo-electric photo-cell and light from the light guide is reflected away whilst in another position (180 degrees later) the light from the guide passes through the disc and reaches the bevelled edge where it is reflected towards the photo-cell 102 and light from the web is reflected away by the outside of the bevelled edge.
