Title: Motion compensating apparatus for continuous television film projection system
IPC: H04N5/253
Filed: 1970-09-04
Abstract: 1319818 Cinematography; optical compensators RCA CORPORATION 4 Sept 1970 [11 Sept 1969] 42388/70 Heading G2E [Also in Division H4] Telecine apparatus in which a xenon flash lamp 23 is required to project each frame of a continuously moving film 11 more than once into the face 25 of a vidicon camera 26 comprises a fixed external 90 degrees corner reflector 29, 29a, and a plurality of internal 90 degrees corner reflectors 31, 31a - 33, 33a, mounted on a turntable 39 which is rotated synchronously with the film movement so that each internal reflector in turn occupies a projection position wherein its faces are parallel to those of the external reflector  and permits the image of a frame to fall on the vidicon face 25, and is characterized in that successive internal reflectors are so disposed that they provide successive projection positions which are displaced to compensate for the motion of the film and to identically position successive frame images on the face 25, Fig.3. Thus in the embodiment shown, employing 20 film frames/ second and 60 television fields/ second, (1:3 ratio), three internal reflectors are provided and the film gate 15 is 5/3 frames wide. When a frame occupies a position A in the gate, the internal reflector 33, 33a, is in its projection position to give an image bounded by rays 55, 55a. One television field later, the frame has moved a distance 5 and occupies position B and the turntable 39 has brought reflector 31, 31a into its projection position, which is displaced by a distance 5/2 in the direction shown, so that the image at face 25 is still bounded by rays 55, 55a. A relay lens 34 and objective 35 are included and the presence of such components as well as the disposition of the reflectors, ensures that backing and lagging film frames in the gate are not projected. Dichrois 36 and 28 are provided so that light from a tungsten lamp 44 is projected backwards through an opaque part of the film provided with reference windows and so only falls on a photo-detector 48 when a film frame is correctly positioned in the gate 15, whereupon the xenon lamp 23 is actuated, as described in more detail in Specification 1315387. The turntable 39, film drive 17, and vidicon scanning coil 37 are driven synchronously using the same power source 22.

Abstract: 1,193,078. Grinding; tailstocks. A. A. JONES & SHIPMAN Ltd., and J. HOULDSWORTH. 22 Sept., 1967 [23 Sept., 1966], No. 42435/66. Headings B3D and B3T. A work support (e.g. a tailstock for a grinding machine) comprises a centre 3 carried by a ram 2, a drive motor 14 connected through yielding means to the ram, means, such as switches, for limiting axial movement of the ram and means for indicating correct or incorrect engagement of the workpiece. To move the centre 3 to the IN position, a tubular housing 17 is moved to the right, Fig. 1, by a nut 11 driven by the motor 14, the end of the housing being provided with a fixed plate 31 and a yieldable sleeve 30 for operating one end 8 of a lever 4, Fig. 3, which is mounted on a shaft 5 for pivotal movement therewith. Spring-pressure on the sleeve 30 may be adjusted by a screwthreaded spindle 23 which is rotated by a knob 24 within a nut 26. The shaft 5 carries lugs (35, 36), Fig. 5 (not shown) for contacting switches (LS1, LS2) which serve to stop the motor 14 when the ram reaches the set limits of travel (so long as the movement remains unobstructed). When the centre 3 engages a workpiece, further movement of ram 2 is stopped but movement of the housing 17 continues so as to apply the spring load. A switch (LS3), Fig. 4 not shown) carried by the shaft 5 contacts a screw (39) to stop the motor 14 when the ram 2 has been loaded by the spring 29. A switch (LS4) carried by the shaft is arranged to contact a screw (40) only when the ram is forced back in the OUT direction, the signal from this switch being used to relieve grinding pressure. A switch LS5 is also carried by the shaft 5 and is set to contact an adjustable stop 47 at a distance corresponding to the travel required for the centre to enter the workpiece; unless the switch LS5 is actuated, other signals become inoperative so that the machine cannot be operated in the presence of incorrect engagement of the centre as in Fig. 6 (not shown). This safety device may be modified, Figs. 8-11 (not shown) for use with varying lengths of workpieces. In this case a sensing arm (60) is moved by the end of the workpiece when the centre has been successfully engaged, the sensing arm moving a catch (61) which makes contact with a switch (LS5) and allows the sensing arm to be pulled clear of the workpiece by freeing spring-levers (53). The various switches may operate indicator lamps. The drive may be hydraulic instead of electric and the switches replaced by valves.

Abstract: 945,958. Digesters. ASSOCIATED PULP & PAPER MILLS Ltd. Dec. 29, 1960 [Feb. 8. l960], No. 44571/60. Heading B1X. [Also in Division D2] Pulp is made from wood or other cellulosebearing material by the alkaline processes (see Division D2) in a continuous digester in which (Fig. 1) wood chips are fed from hopper 11 via chip-meter 12 and low pressure feeder 12<SP>1</SP> to a steaming vessel 13 fitted with a screw conveyer 13<SP>1</SP> and then through a high pressure feeder 14 and pipe line 15 to point 16, at the upper end of digester 10. The chips are then fed downwardly into the digester via the rotating screw 19<SP>1</SP> within the cylindrical screen 19<SP>2</SP> To assist in the feeding of the chips, liquor is withdrawn from the digester at outlet 45 and via pipe line 17 to feeder 14. Cooking liquor is supplied through pipe line 30, pump 31, pump 26, and steam heater 27 and inlet 22 to the cooking zone of the digester, i.e. the part between the sets of screens 20 and 23 and may be circulated via liquor outlet 25 until the required temperature, e.g. 150-180‹ C., is reached. The end point of the cook is determined by testing a pulp sample taken at test cock 32. Black liquor is then introduced under pressure from pump 44 and passes via inlet 42 upwardly into the diffusion-displacement zone of the digester, i.e. the part between screen 23 and the base. Meanwhile, black liquoris withdrawn through nozzle 21. Cooking liquor is meanwhile introduced continuously via 30, 31, 26, 27, 29 and 22, withdrawn through 24 and recirculated through 27, thus maintaining the cooking temperature in the digester. Discharge of pulp is then commenced via outlet 33, black liquor being separated at concentrator 38 and recirculated via pipe line 39, valve 40 and inlet 37. Liquor balance in the digester is achieved by control of operations such that the rate of discharge of black liquor in gallons per minute at 21 is equal to or slightly greater than the sum of (U+S+M+W), where U is the rate of upflow of black liquor in the diffusiondisplacement zone of the digester, S is the rate of introduction of condensed steam with the wood, M the rate of introduction of moisture in the wood, and W the rate of introduction of cooking liquor. To compensate for variations in digester pressure, an inflow of black liquor is arranged through inlet 48 which is controlled by a pressure controller 49 connected to the digester at 50 and responsive to changes in digester pressure. In Fig. 2 water or aqueous acid solution may be introduced at a point 46 above the black liquor outlet 21, heated to the required temperature by an external steam heater (not shown), and passed upwardly through the digester countercurrent to the downward flow of wood chips and discharged at point 47 near the point of entry of the wood. In a further modification (not shown) the flow of liquor and wood may be concurrent during prehydrolysis. Specification 945,957 is referred to.
