Abstract: 1,024,130. Stamping. MINSTER MACHINE CO. Feb. 14, 1964 [Feb. 14, 1963], No. 6305/64. Heading B3Q. A press comprises a slide 18, Fig. 2 (not shown), operated by a crankshaft 32 and guided by columns 14, and in a bed 12, shafts 22, 24 rotatable for indexing work (not shown) are driven by the crankshaft 32. The work may be can-lid blanks in dies indexed between stations at which the blanks are scored to provide a " tear open " lid or lid-section, and a projection raised which is struck down, clamping a tab to the lid. Drive for the crankshaft is from a motor 30, through a pneumatically-operated clutch and brake mechanism 34, permitting continuous or single-stroke operation. The crankshaft is coupled by bevel-gears 36 to a shaft 28 which, through bevel-gears 38, drives a shaft 40 of the indexing mechanism 26, Fig. 8 (not shown). This includes cams 149, 158 engaging between successive pairs of rolls 145, 147 carried by the shafts 22, 24 as they index the shafts and allow the necessary dwell between steps. A sprocket 160 driven by the indexing mechanism, may drive a feed mechanism. Also driven by the crankshaft is an obstructing disc 50, with a single aperture, between a source of light 52 and a photo-cell 54. A similar arrangement (not shown) associated with a movable part of a die set and in circuit with the cell 54, affords a check on synchronisation and can stop the press. The slide 18 may be adjusted relatively to the connecting rods 20 by screwed shafts 110, Fig. 6 (not shown), pinned at 100 to the ends of rods 20. A nut 112 on each shaft 110 and located by a collar 118, secures the shaft to the slide. Keyed to the nut is a worm-wheel 114 rotated to adjust the slide through a worm 116, bevel-gears and a worm-gear, Fig. 7 (not shown), by a hand wheel on a shaft extending to the rear of the slide. After adjustment, a lock-nut 122 on the shaft 110, and having worm-wheel teeth 124, is rotated to secure the adjustment by a worm 126 on a shaft extending to the rear of the slide for operation by a key. This shaft is clamped by oppositely-moving sleeves, Fig. 7A (not shown), operated by a screw. Bearing pads 106 are located between the ends of rods 20 and the shafts 110. Adjustable slideways 60 are fixed to the inner corners of the columns 14 by screws 68, 70. Co-operating members 72 fixed to the slide by screws 76 are adjustable by cylindrical plugs 82 having wedge surfaces 80. The plugs are located by grub-screws 88 and clamped by further screws. Lubricant under pressure is supplied to the slideways, a lubricant pump 44 being driven by shaft 40.

Title: Optical arrangements for maintaining a desired condition of focus of a light beam
IPC: G11B7/09
Filed: 1976-02-18
Abstract: 1526333 Maintaining focus SONY CORP 18 Feb 1976 [24 Feb 1975] 06424/76 Heading G2T A light beam is kept focused at P2 on surface 4b of an optical record irrespective of minor variations in the position surface 4b as the carrier 3 is translated past the reader. As described the light from a source 7 (e.g. a laser) is focused by lens 5 to a point F 1  prior to reflection from the lower surface of a reflective record. The reflected beam repasses lens 5 and is focused at P 1  before being refocused at P 2  by lens 6. An information bearing reflection from surface 4b is passed via lens 6 to detector 13. When the lenses 5 and 6 are so chosen and disposed with regard to points F 1 , P 1  and P 2  that their magnifications (N 1 , N 2  respectively) satisfy N 1 . N 2  = 1/#2, it is  shown that point P 2  will always fall on surface 4b despite any axial wobble as the disc is rotated about axis 1a. In an alternative embodiment both sides of the disc 3 are reflective and the lens 5 directs light at the lowest surface. The housing 15 carries all optical components rigidly and is moved bodily in the radial direction of disc 3 by drive 16.

Title: Circuit arrangements for producing analogue signals
IPC: G11C27/00
Filed: 1976-02-19
Abstract: 1509134 Analogue stores SIEMENS AG 19 Feb 1976 [20 Feb 1975] 06498/76 Heading G4G An analogue value is stored in the form of a phase difference between two identical frequency dividers and the value is modified by altering the relative number of pulses supplied to the dividers. As shown, dividers 1, 2 are supplied from clock 10 through AND gates 5, 6 (line a, Fig. 2). The outputs b, c, Fig. 2, of the dividers having, initially, phase difference # 1 , are fed to a bi-stable 20 followed by a filter 21 which furnishes an analogue signal at output terminal 22. A follow-up circuit 13 comprises a comparator 24 and a two-state logic circuit 27 in which, by means of an appropriate voltage applied to control input 36, AND gates 28, 29 are enabled and AND gates 41, 42 inhibited, or vice versa. In the former state, an inequality between analogue output at terminal 22 and a newly-supplied analogue signal at input 26 is detected by comparator 24 which transmits an inhibiting pulse to one or other of the input AND gates 5, 6 dependent upon the sign of the inequality. One or more clock pulses supplied to one or other of the dividers is or are supressed, with the result that the phase difference is modified to value # 2  and a new output analoque value is supplied. When gates 28, 29 are inhibited, the circuit continues to supply a constant analogue value. This value may be modified to a desired extent by closing one or other of switches 44, 45 whereby inhibiting signals are transmitted from source 46 via one or other of the (enabled) AND gates 44, 45 to-one or other of the input gates 5, 6 of the dividers. The modified circuit of Fig. 3 (not shown) contains a logic circuit identical with logic circuit 27, Fig. 1. In this case, the AND gates 5, 6 are controlled, via the logic circuit, by respective bi-stables which are set (indirectly) by the output pulse of divider 1 and reset by the output pulse of divider 2. The output pulse of divider 1 is initially supplied to set a further bi-stable which initiates integration of a reference voltage by an integrator circuit. When the integrated voltage reaches the level of a decreased analogue value, comparator detects the equality and supplies a pulse to the bi-stables controlling gates 5, 6 whereby one or other of these gates is inhibited until a reset pulse is applied to the bi-stables by the output of divider 2. If the input analogue is increased, gate 6 is inhibited until such time as the integrator output reaches the new value, at which time the gate is again enabled. Thus, depending upon the sign of the change, one or other of the dividers is idle for a fraction of the time between two output pulses.
