IPC: B65H54/58
Filed: 1966-12-28
Abstract: 1,172,820. Winding a skein of threads. PLUTTE, KOECKE & CO. 28 Dec., 1966 [28 Dec., 1965], No. 57997/66. Headings D1J and D1W. A skein of thread is wound on a rotating spool having a conical or pyramidal portion 6 by causing the point of winding to oscillate relative to -the spool in the axial direction of the spool while at the same time undergoing a net axial displacement relative to the spool, winding being started on the conical or pyramidal portion. Either, as in Figures 1 and 3 the spool merely rotates and the thread guide 11 or 44 is caused both to oscillate and to move axially, or else as in Figure 4 the thread guide causes the thread only to oscillate and the spool is caused by means of a hydraulically operated cylinder 66-72 to move in the axial direction. Preferably the thread feeds through slots 48 (Fig. 3) in wheels 49 which correspond to the oscillatory displacement A. The wheels rotate with shaft 37 which rotates with the spool. The shaft 37 is thrust in the axial direction B by a screw shaft 50 rotating through gearing 54, 57, 58 and 59 with the spool. Several reels can be wound on one spool, the spool having a conical or pyramidal portion for each reel. The reels are preferably wound on top of a puckered cover arranged over the spool, the cover length being two or three times the length of spool covered. For easy removal of the cover it is cut and drawn off the spool over conical portions 16 and 13.

Filed: 1970-12-30
Abstract: 1389193 Sorting nails GKN (SOUTH WALES) Ltd 28 March 1972 [30 Dec 1970] 61813/70 Heading G1M An apparatus for sorting nails comprises a guide 1 along which the nails pass points first, a probe 12 which is positioned so that its tip abuts the point of an acceptable nail as it is discharged Fig.2, (not shown) but not that of an unacceptable nail Fig.3, (not shown), a hopper 3 into which the nails fall, and a flap 7 operated according to whether or not each nail point has contacted the tip of probe 12 to open an accept aperture 5 or a reject aperture 6. In one embodiment (not illustrated), acceptable nails electrically bridge the gap between probe 12 and guide 1 to move flap 7 to the accept position. In another embodiment (not illustrated), unacceptable nails strike an axially slidable sleeve mounted on probe 12 which controls flap 7. In the preferred embodiment shown in Fig.1, the probe 12 is mounted on a piston 13 movable axially when a nail strikes the tip of probe 12, against the bias of air pressure in a cylinder co-operating with piston 13. A rod 18 is mounted on piston 13 and has an aperture cooperating with an air jet sensor 19 such that the air jet is normally interrupted but is allowed to pass when piston 13 moves axially under the impact of an acceptable nail. A second air jet sensor 41 is provided which detects the passage of each nail past the end of the guide, each nail interrupting the air jet. If an unacceptable nail is discharged, it first interrupts air jet 40 and thus momentarily removes the control pressure applied through line 42 to monostable fluid logic device 43. As a consequence, a pressure pulse is applied via line 45 to fluid logic device 22 so that pressure from line 23 is switched into line 25 and operates a control valve 27 via a restrictor 26 to move flap 7 to the reject position by means of pneumatic ram 32. Pressure is also applied via line 25 to a diaphragm amplifier 29 to cause a pressure to be built up in a reservoir 35, this pressure being applied to device 22 to switch it to its original position so that flap 7 moves back to the accept position. If an acceptable nail is discharged, shortly after the interruption of air jet 40 causes line 25 to be connected with line 23, a pressure pulse is applied to device 22 by air jet 19 to switch device 22 to its original position before the control valve 27 operates, and flap 7 remains in the accept position.
Patent GB-625484-A (GB)
Abstract: 625,484. Radiolocation. SUBMARINE SIGNAL CO. Nov. 9, 1945, No. 29935. Convention date, July 29, 1940. [Classes 40 (v) and 40 (vii)] [Also in Group XXXVIII] In a reflection-type ranging system using radio or compressional waves, the frequency of the signal transmitted during the recurrent periods a-b, Fig. 1, is varied linearly according to the curve 2, Fig. 1B, and the tuning of the receiver during the later recurrent periods c-d is varied in an inverse manner as shown in the curve 4 so that reflected energy having a transmission time intermediate between b-c and a-d is passed by the receiver, the range being a function of the instantaneous frequency of the receiver at the time of reception. Since the longer ranges, e.g. y, are given by the low frequencies and the shorter ranges, e.g. x, by the high frequencies, the amplitude of the transmitted signal and the receiver gain are varied exponentially as shown respectively in Figs. 1C and D in order to compensate for the increased attenuation of the longer range reflections and reduce the effect of spurious short range reflections. In Fig. 2 (not shown), the transmitted signal is produced by varying the frequency of a master oscillator as shown in Fig. 1A and applying the output to the transmitter through a blocked amplifier which is rendered operative during the period a-b, its gain being varied according to Fig. 1C. The received signal is heterodyned with the master oscillator frequency which is constant during the reception period c-d, giving a beat frequency F the instantaneous value of which as heard by the operator and indicated on a meter is proportional to the range of the signal being received at that time. Since the range is also a function of the time of reception of the signal it may be indicated by a rotating disc carrying a neon light which is illuminated by the received signal. The linear frequency variation shown at A could be approximated by a single harmonic function or a combination of straight line and exponential functions and may be produced by mechanical means or by electrical means such as disclosed in U.S.A. Specification 1,830,166, or by controlling the resonant element of a klystron when very high frequencies are employed in which case a klystron could also be used in the receiver. Fig. 3 (not shown), illustrates a system adapted for acoustic and supersonic ranging in which the tuning and gain of the transmitter and receiver are controlled by mechanically ganged rotating condensers and biassing potentiometers. Alternatively the amplitude variation of the transmitted signal may be produced by using a transmitter with a peaked resonance curve, Fig. 4 (not shown), such as disclosed in U.S.A. Specifications 1,167,366 and 1,604,693.
