Abstract: 1,052,715. Double-twist spindles. J. J. KEYSER. June 22. 1965 [July 2, 1964], No. 26334/65. Heading D1D. In a double-twist spindle having a rotatable hollow shaft 8, Fig. 1, not shown, carrying a storage-disc 9 and a thread-guide plate 10, the bobbin carrier is suspended from a sleeve 17 rotatably mounted relatively to the shaft at the upper end thereof, so as to extend downwardly towards the storage disc and to surround the shaft with radial clearanec. A tube 15 is mounted in bearings in the shaft 8 and carries the inner races of the bearings. The bobbin cage 19 is carried by a ring 20 which is secured on a shoulder of the sleeve 17, screwed etc, on to the upper part of tube 15, by a cap 21 screwed on to an upper extension of the member. This cap houses a thread-brake 22 and has screwed thereon a thread guide-tube 23 on which is rotatably mounted a cap 24 carrying the flyer 26. The bobbin-cage comprises a number of U- shaped wire members 19, 30, 31 extending between the ring 20 and a thread-deflector ring 32, which can be deformed to take bobbins with sleeves of different characteristics, and which carry stabilizing-magnets 33 which may serve to interconnect parts of the cage. The cage, together with the tube 15 with the inner bearing-races and cages and the parts 17, 21, 22, 23, 24 and 26 comprise a removable unit. The bobbin, with sleeve 28 can be inserted and the tube 15 threaded-up, outside the machine. The disc 9 and plate 10 are secured to the tube 8 by yarn bushes 35 through which the thread can be drawn pneumatically from tube 15 for threading-up. In another form, Fig. 3, not shown, a tube with a plastics lining to reduce friction on the yarn, is inserted in tube 15 and the cap 17 is screwed on to the inner tube. The tube 15 remains in position when the cage and associated parts are removed.

Abstract: 1,060,038. Shaft encoders. CSF-COMPAGNIE GENERALE DE TELEGRAPHIE SANS FIL. April 13, 1965 [April 15, 1964], No. 15839/65. Heading G4H. In the shaft-position encoder comprising toothed stators (3, 3a, Fig. 1, not shown) having windings spaced by 1, 2, 4 &c. teeth, a fingerlike rotor (4), connected to the shaft (10), a primary winding (11) causing flux to circulate through the rotor and certain of the stator windings so that their outputs represent the shaft position as a binary number, the lowest valued winding (2) is on stator (3) and the others (2a, 2b) are on stator (3a) and rotor (4) co-operates with both stators while rotor (4a), which is offset from rotor (4), co-operates only with stator (3a) and is energized by winding (1a) fed with a voltage in phase with the output of winding (2). This arrangement ensures that the signals from the higher order windings do not appear before the signal on the lowest order winding. A number of encoder units may be geared together (Fig. 7, not shown). The primary windings (1, 11 &c) are all fed by voltage (U) from oscillator (13). The outputs of windings (2, 2a and 2b) pass via amplifiers (5) to bi-stable circuits (6, 6a, 6b) enabled by a signal derived from voltage (U) by a phase changing circuit (14). The output of bi-stable (6) is connected to a generator (17) of square signals to feed the auxiliary primary windings (la, 11a &c.). The outputs (I-V) are " 1 " or " 0 " according to the state of the corresponding bi-stables. The synchronizing pulses form circuit (14) may occur at the maximum of the reference voltage (U). The auxiliary windings (1a, 11a) are energized by a circuit (17) supplying square wave signals the phase of which is controlled by the state of the lowest value bi-stable (6) so that all the outputs are properly synchronized.

The rolls 4 are mounted to rotate counterclockwise on a shaft 41 and the roll 12 is mounted to be swung upwardly about a stationary shaft 123 so as to permit the passage therebelow of the corrugated tube. Each plate 5 is adjustably mounted on a frame 18 by a rod 52. The member 6 is of subsantially U- section and comprises teeth 61, 62, see also Fig. 10 (not shown), extending from a web portion 63. Arms 64 pivotally mount the member 6 on a shaft 65 and springs 7 urge the member towards the belts 1. A member 11 of cross-section similar to the member 6 is fixed between the roll pairs 9, 10 and 13, 14. The surfaces of the rolls 4, 12 and the plates 5 are covered with rubber or other highly frictional material. The rolls 9, 10 are made of relatively hard material and have a knurled surface. The rolls 13, 14, 15, 16 are covered with sponge rubber or other resilient material. In operation, the tube A becomes pinched between the rolls 4, 12 and the plate 5 and during its advancing movement the lower half is held from movement by the friction exerted by the plates 5 while the upper half is advanced by the rolls 4, 12 until the entire tube is forced into the squeezing space and compressed to form the corrugations. The roll 9, which has been maintained at a lower position to provide a space between it and the roll 10, and the roll 12 move upwardly. The corrugated tube passes between the rolls 9, 10, beneath the roll 12 guided by the member 11, and then between the rolls 13, 14, 15, 16. As the trailing end of the tube A departs from the roll 12. the rolls 9, 12 begin to move downwardly.

Abstract: 1,225,904. Measuring deflection. R. LUDI A.G. 6 June, 1969, No. 28878/69. Heading G4H. To measure the deflection of for example the pointer 6 of a meter of a measuring mechanism, the displacement of a vane 8 moving with the pointer 6 is measured by counting the number of steps necessary to bring a sensing arm 16 carrying a sensing head into alignment with the vane. As described when the vane is not in a gap 18 in the sensing arm 16, sufficient coupling exists between coils 22 on the arm 16 that oscillator 20 oscillates to enable a transducer 32 which generates pulses to step a motor 10 and increment a counter 38 until the vane 8 enters the gap 18, when the count is stopped. The count then represents the displacement of the pointer 6. Instead of stepping motor 10, an electromagnetically actuated pawl drive may be used. Photo-electric sensing may replace the oscillator and coils. The shape of the vane prevents backward hunting.

Abstract: 1,230,703. Telegraphy. MARCONI CO. Ltd. 18 Aug., 1969 [15 Nov., 1968], No. 41077/69. Heading H4P. To correct a pulse code modulated bipolar communication signal, departure from correct polarity due to insertion or omission is detected and an indication is given of the interval during which the error has occurred which causes signals to be nullified during the interval. The bipolar signals may be derived from a "non- return to zero" code. In Fig. 1, line A represents a binary signal, B a corresponding transmitted bipolar signal and C indicated at X1 &c. possible errors on reception. Departure from correct bipolarity provides an indication that an error has occurred in an interval of a certain number of bits varying theoretically from 2 to # but practically it can be shown that the average length of such inter. val will be 3 bits for errors of insertion and 4 bits for errors of omission, and an expression for probability of error is developed in the Specification. A signal indicating the presence of errors shown at D. A known memory circuit functionally associated with a gate circuit is arranged to nullify word codes that contain errors. The memory should have a capacity of 1 greater than the word code i.e. in the example given a capacity of 7 + 1 bits. It is stated that the average signal to noise ratio is practically independent of the signal within a useful range of signal strengths and that the invention allows an increase in error rate of 30 times or alternatively a noise reduction of a approximately 15dB.
