Abstract: 1,183,898. Gyroscopic apparatus. SOC. D'APPLICATIONS GENERALES D'ELECTRICITE ET DE MECANIQUE S.A.G.E.M. Oct.24, 1968 [Oct.31, 1967], No.50509/68. Heading G1C. Apparatus for providing a line of sight L-L comprises a telescope 4 for receiving light passing along the line L-L after reflection in a mirror 2 pivotally mounted about an axis X-X in a gimbal 5 in turn mounted for rotation in a support 6 about an orthogonal axis Y-Y, the attitude of the mirror 2 being stabilized by a reference platform 7 itself stabilized by two gyroscopes 9, 11 and mounted for rotation in the gimbal 5 about an axis Z-Z parallel to the axis X-X and coupled to the mirror by means 8 providing a reduction of 0À5 between the pivotal movements of the platform 7 and mirror 2, the input axis E 1  of the gyroscope being parallel to the axis X-X movements about this axis being detected by an angle detector 14 controlling a torque motor 10 for the platform 7, and the gyroscope 11 being disposed with its input axis E 2  parallel to the axis Y-Y and similarly provided with an angle detector 16 coupled to a torque motor 12 so that the platform 7 controls the attitude of the mirror 2, a switch 18 additionally being coupled to provide an additional biasing torque from the motors 10, 12 when actuated. As an alternative to the switch 18 acting directly on the motors 10, 12, it may be coupled to actuate additional torque motors rotating the gyroscope rotors about the degree of freedom provided by their supporting gimbals, thus actuating the angle detectors 14, 16 and the torque motors 10, 12 indirectly. Also, the gyroscope 9 may be disposed with its spin axis S 1  parallel to the axis Y-Y to avoid coupling between the two gyroscopes.

Resistors of differing resistances are fed from vibrating bowl 1 and fall down shoot 3 whence they are fed by drum 4 down shoot 5 to be received singly in a pocket 16 of intermittently rotating disc 15. The disc 15 feeds the resistor to measuring contacts 19 which are pressed against the resistor by cam 20 operating via levers 21, 22. Contacts 19 operate measuring unit 14 which operates electromagnets 24. These act via levers 27 to displace upward rods 28 of a presetting mechanism into one of the fixed racks 40. At the same time the resistor drops into a trough 35 carried by rotary disc 37. Disc 37 carries round the trough 35 until dogs 30 carried by the disc engage the displaced rods 28 which causes lever 36 to engage cam 42 and open the trough 35 to release the resistor into the appropriate shoot 53 and storage means 23.

Title: Error detecting apparatus
IPC: H04L1/00
Filed: 1970-10-28
Abstract: 1328163 Error detection in digital data signals INTERNATIONAL BUSINESS MACHINES CORP 28 Oct 1970 [5 Nov 1969] 51104/70 Heading H4P [Also in Division G4] A data transmission system or a magnetic disc recording/playback system prior to trans_ mission or recording, generates from parallel or serial coded binary digits a checkword which consists of a first group of digits derived by logically gating the coded binary digits together and a second group of digits derived by employing counting means clocked at the rate of the coded binary digits and logically gating the output of the gating means with the coded binary digits, which checkword is also transmitted or recorded with the coded binary digits. A corresponding checkword is derived from the received or played-back data signal and compared with the received or play-back checkword in order to correct errors. Fig. 2 shows an arrangement for deriving the checkword at either the transmitting or receiving end. Serial data is fed into a shift register 34 via an exclusive OR gate 36 also receiving the circulated contents of the register, the output of the register via gate 38, when all the data has been fed in, forming the first part of the checkword. At each 1-bit of the data the state of an m-stage counter 22 is fed in parallel form through an AND gate 24 to an exclusive -OR gate 30 which also receives m stages of register 26. The output of the OR gate enters register 28 along with the remaining b stages of register 26. Prior to each data bit the contents of register 28 are put into register 26 with a circular shift of one bit. The serial output of register 28 via AND gate 32, when all the data has been fed in, forms the second part of the checkword. At the receiver a comparison of the transmitted and locally generated checkwords yields a syndrome sequence which is decoded to derive the positions in the received data of erroneous bits. Further arrangements are described for handling data in parallel form and for deriving in disc recording additional check bits indicative of the recording track from which an erroneous sequence was taken.

Abstract: 1441792 Device for preparing cops for unwinding W REINERS VERWALTUNGS GmbH 9 Nov 1973 [14 Nov 1972] 52075/73 Headings D1F and D1J A device for preparing oops 3 for unwinding in which the cops are guided by transport means e.g. pocketed conveyor 1, on a path 6 along the contact line 7 of two rotating parallel rollers 8 and the thread end 10 is drawn off by the rollers, includes a conveyor plate 11 arranged in the guide path below a support 6 for the cop tube feet 5', the conveyor plate 11 having a plurality of yarn engaging teeth 12 and being displaceable transversely to the direction of transport of the cops. The support 6 is provided in the vicinity of the plate 11 with a corresponding number of tooth gaps 13. In use, the cops 3 are conveyed along the support 6 and the free thread end is gripped and drawn off by the rollers 8. When the cops pass the plate 11, the thread end 10' is engaged in the first tooth and tooth gap 12, 13. As the cop tube 5 passes the plate, a magnet 16 is actuated whereby the plate 11 performs a swinging movement transverse to the direction of cop travel, and the gripped thread end is moved to the next adjacent tooth gap. The length of thread pulled off the cop therefore increases as the cop travels and a cutter 15 is operated on each actuation of the magnet whereby the thread end 10' engaged in the last tooth gap 13' is severed and the end sucked into a store 14. The device ensures an adequate length of thread 10' is drawn off prior to the next processing step e.g. in an automatic winder.
