Title: Apparatus for measuring the speed of a ship
IPC: G01P5/08
Filed: 1965-12-28
Abstract: 1,109,520. Electric selective signalling. CHESAPEAKE INSTRUMENT CORPORATION. 28 Dec., 1965 [28 May, 1965], No. 54986/65. Heading G4H. Flow of water past the hull of a ship generates signals to control a feedback positioning system, the discrete output of which indicates ship speed. The difference of an A.C. voltage from a rodmeter (62) on the hull and a feedback voltage from a potentiometer (40, Fig. 3b, not shown) is obtained by a transformer (34, Fig. 3a, not shown), amplified and then rectified in a phase sensitive detector (84, Fig. 3c, not shown) to gate clock pulses from a time base circuit (150, Fig. 3c, not shown) via amplifiers to logic circuitry (196, Figs. 3d, 3e, not shown) to derive pulses for driving a bi-directional stepping motor (38, Fig. 3e, not shown). The stepping motor drives the feedback potentiometer (40), a speed indicating dial (42), data transmission synchros (32), and a mechanical integrator (22, Fig. 3d, not shown). The rotational output of the latter, representing distance travelled, drives a cam pulse generator (300, Figs. 3d, 6, not shown) to energize a stepping motor (302) which drives a distance counter (28) and data-transmission synchros (298). The rodmeter voltage may be replaced by a test voltage selected by a dial (366, Fig. 3a, not shown). The time base circuit (150) may operate at either of two rates, selected manually (164), the slow rate being changed to when water turbulence or the ship's motion other than forward speed is causing the system to oscillate, to render the system unresponsive to other than slow changes of speed. Pulses from the time base circuit (150) may also be passed to the logic circuitry (196) via a manual switch (342, Fig. 3c, not shown). The potentiometer in the feedback loop (40, Figs. 3b, 5, not shown) comprises a series of calibrating potentiometers (234 to 252) having the ends of their resistors connected to respec. tive fixed tapping points on an autotransformer (258) and being preset to compensate for non- linearities in the total system and any zero error. The angular position output of the first stepping motor (38) positions the wiper of a 360 degree toroidal resistor of an interpolating potentiometer (256) and also connects three taps equally spaced around this resistor to the wipers of respective adjacent ones of the calibrating potentiometers (234 to 252). As the wiper of the interpolating potentiometer (256) moves in one direction or the other, the connection to the third of the calibrating-potentiometer wipers is broken and remade to the wiper in front of the first connected wiper. Then the connection to the new third wiper is broken, etc. (Fig. 5, not shown).

Abstract: 1292646 Holography: fingerprint identification cards KMS INDUSTRIES Inc 12 Nov 1969 [12 Nov 1968] 55267/69 Heading G2J [Also in Division G4] In forming an identity and incorporating a Fourier transform hologram of a fingerprint a beam from a laser 20 is divided into a reference beam 30 and object beam 40, a transparent plate 46 having a surface carrying an impressionable film to receive the fingerprint is located in the path of the object beam and a photo-sensitive plate 52 recording the hologram of the fingerprint is located in the Fourier transform plane of a lens 44. In identification a shutter 60 blocks-off the reference beam. An identity card bearing the hologram of the fingerprint is located at the position of plate 52. A finger is rolled over plate 46 to form a "real-time" fingerprint. The Fourier transform of this fingerprint is superimposed upon the hologram. Where the two fingerprints match a light output is achieved which is detected by a photo-detector 70. To check that the correlation is correct a rotating apertured plate 80, or a vibrating plate, is interposed between hologram and detector 70. This enables the light intensity peaks to be detected.

Abstract: 1322458 Knitting machines E MAYER [trading as MAYER & CIE] 30 Nov 1971 [17 Dec 1970] 55471/71 Heading D1C In a circular knitting machine having, at each knitting system, a pin drum 50 moved step-by-step n steps per rotation where u is the number of rows of pins there is a counting disc also with n steps per rotation and rotatable with the needle cylinder n/a-1 advance cams 57 where a is an integer arranged for switching the drums a steps at a time. As shown each drum 50 has e.g. 32 rows of pins which co-operate with pattern slides and is rotatable in single or double steps. Cams 57 and one pattern cam 58 rotate drums 50 and the counting disc 55 of a counting mechanism by one or two steps as set. At a regulating point 59 a switching device 60 actuated by disc 55 decides if cam 58 and cams 57 are to become effective by means of switching device 60. Regulating point 59 comprises a bolt 61 shifted by a Bowden cable 64 which engages a pawl 76 which holds a guide member 72 against spring 71. On top of member 72 is switching cam body 73 and according to which stop pawl 76 engages the cam body 73 can take up three positions. These are positions one in which it does not effect the switching roller 80, position two in which the narrow part of body 73a is in the path of rollers 80 causing drums 50 to move one step and position three in which body 73 is fully raised and mechanism 54 and drums 50 are moved two steps. In this position, body 78 may also be raised to cause double step movement of drum 50 by cams 57. Roller 80 is fastened on a slider 81 which transmits movement through a percussion lever 82 to a pawl 83 biassed to its normal position by a spring 84. Pawl 83 engages a toothed wheel 85 coaxial with disc 55 having notches 86 and crests 89 for each even and odd numbered pin row respectively and a deep notch 87 at row 1 which forms an indexing position. A sensor 91 co-operates with disc 55 and is carried on a swivel axis 90 which through lever 91 and pin 92 engages lever 93 connected through a further lever to cable 64. A roller 97 on lever 93 engages low links 100 medium links and high links 107 of chain 98. (For Figures see next page)
