Abstract: 1,169,810. Typewriters. INTERNATIONAL BUSINESS MACHINES CORP. 4 Dec., 1967 [28 Dec., 1966], No. 55019/67. Heading B6F. A power driven typewriter, in which a selected serrated cam 31 coacts with a continuously driven power roll (39), Fig. 1 (not shown), to effect an impression, includes impact adjustment mechanism responsive to a case shift and comprising an adjusting lever 101 for adjusting the impression density of characters of both upper and lower cases without altering the ratio of impression density therebetween, and a ratio control device 135 for altering the ratio. The impression density of each character is controlled by a finger 61 coacting with a heel 37 of a corresponding cam 31 to disengage the cam from the power roll. The fingers 61 rest on upper and lower case stop screws 57, 59 each individually adjustable for letter-by-letter impact adjustment and mounted on a bar 55 rocked by the case shift mechanism 69. The bar 55 is moved vertically to effect proportional adjustment of upper and lower case character impression densities, or at an angle to the vertical to adjust the ratio of the impression densities, according to the orientation of a slot in a guide 133, by rotating the lever 101 which acts through a link 107 and a crank 109 to rotate a cam 119 towards which an arm 121 is spring-urged, the arm 121 being connected at 129 to a plate127 in which is cut a kidney-shaped camming aperture 143 which receives a roller 141 mounted on a pin 140 fixed to the bar 55. When the slot is orientated vertically, the plate 127 and hence the bar 55 is moved vertically under the action of the lever 101 and both upper and lower case character impression densities are varied in proportion. If the slot is not vertical, the plate 127 will move in a direction inclined to the horizontal and the roller 141 will move sideways in the aperture 143. The left hand side of the aperture, corresponding to lower case, is shaped so that sideways movement of the roller therein has no effect on the position of the finger 61, whereas the right hand side is shaped so that sideways motion of the roller changes the position of the finger 61 in the upper case relative to the position of the finger in the lower case. The orientation of the slot is altered by rotating the ratio control device 135. The range of impression densities obtainable by rotation of the lever 101 may be varied by connecting the link 107 to different holes 111A . . . 111D in the crank 109. The impression density of small surface characters such as a comma is controlled by additional stop screws (161, Fig. 1) mounted on a bar 159, and adjustable individually only.

Patent GB-568753-A (GB)
Abstract: 568,753. Two stroke engines. CASTELLlNI, A. P., and ROBEY & CO., Ltd. July 14, 1943, No. 11446. [Classes 7 (ii) and 7 (vi)] A two-stroke internal-combustion engine has air or mixture compressed in the crank-case and then transferred to the combustion space by valves which are mounted together with their operating gear in the piston-head and are actuated through the swinging movement of the connecting rod on the gudgeon pin. As applied to a V-engine with cylinders arranged at 45 degrees, Fig. 1, each cylinder casting 1 is fitted with a head 3, cooled by water jackets 6 and having an exhaust port 5 and fuel inlet 4. The crank-case is fitted with air inlet valves 11, operated against closing springs 17 by cams 13 on a shaft 13a driven from the crank - shaft. The air supply may, as shown, be increased by means of a supercharger 25, connected by passages 26 to the air valve chamber 26a. If light fuel is used, the supercharger induces its air through a carburetter or mixture may be induced by piston suction. The free space within the crank-case may be reduced by the provision of boxes 27 secured concentrically to the crankshaft and arranged to embrace the crank-webs. The air compressed in the crank-case is admitted to the combustion space through piston-head poppet-valves 31, 31a closed by springs 31b. The valves are actuated by rockers 35 mounted on pins 36 and operated by a roller 40a, Fig. 3, on a cam 40 on a shaft 41. The cam has a portion 44 urged by a spring into contact with a fixed abutment on the connecting rod. During the swing of the connecting rod to the right, Fig. 1, the roller 40a can yield until it has passed over the part 39, but on the return movement to the left the valve 31 is opened. The valve 31a is simultaneously operated by similar mechanism. The fuel pump 51 is driven from a shaft 52 geared to the crankshaft which also operates the exhaust valve cam-shaft 53. Lubrication of the piston is effected from the crank-shaft duct 65 leading through passages 66-68 to the bearing liners 69a and thence through passages 70, 71 to the small end and cylinder walls. To reduce contamination of the air from oil spray, the crankpins have throwing collars 80 which direct oil to a plunger pump operating in the manner described in Specification 568,784. The timing, both for the combustion chamber valves and the crank-case valves, is described in the Specification. In place of compression ignition, the charge may be spark ignited. Different timings of the valves 31 may be obtained by the use of interchangeable cam-shafts 41 with different settings. In addition to V and in-line engines, the invention may be applied to radial engines, the crank-case inlet valves being dispensed with and air or mixture supplied by a supercharger.

[Also in Division G2] Apparatus for storing and supplying recording tape comprises a cartridge member, including a first integral flange and hub portion on which the tape is coiled and a second dished cover flange which is resiliently urged towards the first flange to hold the tape in position, and a rotatable cartridge carrier with means for moving the first flange away from the dished flange to allow the tape to be unwound. The tape is wound on hub 20 which is integral with the lower flange 22. A coupling member 28, which includes a ring 30 and three connector members 32 passing through apertures in an inwardly directed flange 23 of the hub, is snap-connected to the upper dished flange 26 and is urged apart from the flange 23 by spring 36. This spring action urges the dished flange into contact with the tape coil. In use the cartridge member is mounted on shaft 40 in a well 10 of a recorder. Downward pressure moves the member and platform 60 downwards against the action of spring 66 until latch mechanism 70 engages and holds the platform in its lowered position. Downward movement of shaft 102 by manual operation of lever 108 now moves three actuating members 114 downwardly and pivots them outwardly through slots 130 in the spindle body into contact with the upper surface of the inwardly directed flange 23. This movement draws the hub and lower flange downwards away from the dished upper flange to a position which allows tape to be removed from the reel. Return movement of the shaft 102 brings ring 81 at the head of the shaft into contact with a projection 80 in a trip element 78 which on being pivoted releases latch mechanism 70 and returns the cartridge member to its upper position from which it can be removed from the recorder. The platform and cartridge are driven via belt 54 and pulley 52.
