Title: Means for altitude stabilization of a spacecraft
IPC: G05D1/10
Filed: 1964-05-08
Abstract: 1,059,846. Automatic attitude control. BOLKOW G. m. b. H. May 8, 1964, [May 9, 1963], No.19249/64. Heading G3R. In a system for stabilizing the attitude of a spacecraft relative to radiation from a celestial body, an attitude correcting device is switched on if attitude deviates from a desired attitude into a range of small deviation, but is switched off if the attitude returns to the range of small deviation from a range of greater deviation. In Fig. 1, optical systems 2, 40 carried on a spacecraft project light from a celestial body, e.g. the sun, on to opaque sections 7, 37 when the attitude of the missile is correct about two axes. If the attitude deviates to a small extent about one axis, light passes through a transparent section 6, as shown, to a photo-cell 19 the output of which is amplified. The change in amplified output due to the deviation is differentiated and sets a bi-stable circuit to open a gate so that the output is effective to turn on a thrust jet correcting the attitude. Should the deviation increase further, however, light passes through a transparent section 5 to a photo-cell 18 the output of which is amplified and maintains the attitude correcting means in operation. When the deviation decreases to return the light to section 6, the change in amplified output is differentiated and resets the bi-stable circuit to close the gate and turn off the jet. Four systems identical to that described are provided to correct the attitude in either sense about two axes.

Title: Improvements in or connected with coining presses
IPC: B21D55/00
Filed: 1950-08-03
Abstract: 685,949. Stamping. TAYLOR & CHALLEN, Ltd., and CHALLEN, H. D. Aug. 3, 1951 [Aug. 3, 1950], No. 19369/50. Class 83 (iv). Coining.-A coining press is characterized by the incorporation of a feeler arm under which the formed coin is fed during the feeding of the next blank to the dies, said feeler arm being connected to trip mechanism which automatically stops the press if the feeler arm is not engaged by the formed coin. In an embodiment of the invention, the gripper arms of a coining press feeding mechanism as described in Specification 676,562, feed a formed coin by means of arcuately recessed end faces 7a to a position in advance of the dies adjacent a shoot 8 down which the formed coins are discharged. A feeler arm 9 bears on the table 10 of the press adjacent the dies in the position to which the formed coin is fed by the gripper arms 7 after extraction from the dies. The feeler arm is mounted in one end of a lever 11 rockable about an axis 12 the other end of the lever bearing on a trip rod 13 which passes through a slot in a vertically spring-loaded plunger 15. The rod 13 is connected to one arm of a bell-crank lever 16 the other arm being connected to the clutch-disengaging rod 18 of the press. When the feeler arm 9 contacts the table 10 the rocker lever 11 allows the spring- loaded plunger 15 to raise the rod 13 into the path of a cam-operated bell-crank lever 19 which is operated once during each cycle of the press, and the consequent movement of the rod 13 disengages the clutch. When a coin is disposed beneath the feeler arm the rod 13 is depressed and removed from the path of the lever 19. In another embodiment the feeler arm 9 is mounted on a spindle 21 rotatable in bearings 22 and carrying at one end an arm 23 which bears under a projection 24 on a trip rod 25. The end of the trip rod adjacent its pin- and-slot connection to the frame of the press bears against one arm of a spring-loaded bellcrank lever 28, the other arm of which bears against a clutch-operating rod 29 of the press. The free end of the tip-rod has a T-shaped head 30 engaging either one of a pair of camoperated spring-loaded bell-crank levers 31 and 32 pivoted on a common axis 35 and operated once during each cycle of the press. The lever 31 is provided with a foot 36 which extends below the lever 32. In operation, when a formed coin is below the feeler arm the trip-rod is raised so that the foot of lever 31 passes beneath the rod and the rod is not moved longitudinally to operate the clutch. The bell-crank lever 32 is operated during the cycle of operation when no coin should be beneath the feeler arm so that if the formed coin has not been discharged to the shoot 8 the lever 32 will engage the raised trip rod and disengage the clutch. If there is no coin beneath the feeler arm then the trip rod will be in its lowered position and the lever 32 will pass over it.

Abstract: 1,039,216. Selecting cards. N.V. OPTISCHE INDUSTRIE " DE OUDE DELFT ". May 7, 1965, No. 19388/65. Heading G4M. Cards not having a given characteristic have an elongated hole at the corresponding position (the hole may be slotted out to the top edge of the card) and cards having the characteristic have a circular hole at that position, and the arrangement is such that after inserting a selector rod relative vertical movement is effected between the rod and the cards so that cards not having the characteristic remain standing on the bottom of the card box. In Fig. 3, the outer box 7 acts as the card box and perforated walls and partitions 9 of the inner box act as guide plates for selector rods 15, 20. To select cards having a plurality of characteristics, a selector rod is inserted in the first position, rod 8 is pulled out so that pins 3 fixed to the inner box ride up one step on slides 4 whereby selected cards are raised on rod 15 and non-selected cards remain on the bottom of box 7. Rod 15 or rod 20 is then inserted in the second position and the inner box raised another step and so on so that eventually all cards having all the characteristics sought are raised at least one step above all the other cards. Selected cards may be removed on a rod inserted through a special hole. The cards may be formed with two compartments for documents, films etc. The cards may also have a slot having a length corresponding to the maximum number of steps possible, so that after selection, a rod may be passed through this slot and depress to push all cards to the bottom of the card box. In another embodiment, Fig. 4 (not shown) the inner box has a bottom and acts as the card box, slides 4 being reversed so that the inner card box is lowered when rod 8 is pulled out, non-selected cards being lowered with the box. The inner box may be provided with rubber strips to grip the edges of the cards so as to prevent raised cards from falling back when the selector rod is withdrawn and to prevent non-selected cards being raised by adjacent selected cards.
