Title: Improvements in or relating to recording apparatus
IPC: G01D15/06
Filed: 1947-02-19
Abstract: 624,580. Recording-apparatus. HUGHES & SON, Ltd., H., and SPARLING, S. C. Feb. 19, 1947, No. 4804. [Class 106 (iv)] Apparatus comprising a pivotally mounted arm with means for recording electrical impulses on a roll of paper against the angular displacement of the arm is characterised in that the arm carries an elongated recording element whose movement results in the movement of the recording point (i.e. the point where it contacts the paper) along the recording element with different points along the element coming into contact with the paper, thereby producing a rectilinear trace on the paper. An arm 10 is mounted to rotate on a vertical spindle 11 and carries a wire element 12 which sweeps across a paper strip 15 as the strip rests on a bar 16 of small diameter in passing from a roll 17 to guide rollers 18, 19. If the angular velocity of the arm 10 is constant, the distance-time ratio of the rectilinear trace is variable. Fig. 4 shows means for producing a constant ratio wherein the arm 10 is mounted on a pivotally supported carrier 20 having rollers 21, 22 engaging opposite sides of an appropriately shaped cam 23. In the embodiment shown in Fig. 5, the paper strip 12 passes under a roller 16 of small diameter which acts as an electrode in co-operation with the recording element 12 on the arm 10 which is disposed mainly inside a casing 31. Electrical impulses cause discolouration of the paper which can be observed from above as the paper passes over the casing 31. Specification 495,265 is referred to.

Title: Backward extrusion presses
IPC: B21C23/21
Filed: 1961-02-09
Abstract: 959,099. Extruding. L. SCHULER A.G. Feb. 9, 1961 [May 4, 1960], No. 4846/61. Heading B3P. A backward flow extrusion press comprises a die fixed to a ram and two punches fastened to a punch holder pivotally mounted on an axis parallel to and spaced from the axis or centre of the ram, so that pivotal movement of the punch holder allows the two punches to align alternately with the die, which movement is controlled by stops. In an embodiment, a motor 6 mounted on an extension 5 of the press frame 1 oscillates a main crank-shaft 16 connected to the press ram 20 through a clutch 8, gears 9<SP>1</SP>, 11 on shafts 9, 10 respectively, and a connecting rod 13. A press table 23 is adjustably positioned in the frame by means of a hand wheel 80. Pivotally mounted on a shaft 26 mounted in the frame is a vee-shaped punch holder 25 carrying near the end of each arm a punch 28, 29. The punches carry stripper rings 30 which consist of a plurality of segments spring- pressed against the punch. The limit positions of the punch holder 25 are determined by adjustable keys 31 which accurately align the punches with the die on the ram 20. The shaft 26 is driven by a torsion bar 35 coaxial with the shaft and carrying a crank arm 36 provided with a roller which engages a cam slot 39 in a drum 40 driven by the shaft 10. The outer end of the shaft 26 carries a sprocket-wheel 44 which is connected to a sprocket-wheel 46 on a shaft 47. Splined on to the shaft 47 is a vee-shaped magazine 50, Fig. 6, with recesses 51, 52 for the reception of blanks. The recesses are formed of spring-loaded shanks 53 and 54 of two pairs of pivoted tongs. In operation, the punch 29 pushes a blank gripped in recess 51 into the aligning cavity of the die 59 and backwardly extrudes the blank. The ram 20 and magazine 50 are retracted during the following idle stroke until the punch and pressing are clear of the magazine. The cam slot in the drum 40 then deflects the punch holder 25 and the magazine until the punch 28 and the recess 52 axially align the die in readiness for the next extrusion operation. The blanks are loaded into two sorting drums 60 fixed to the press frame and feeder ducts 61 lead the blanks to the magazine 50. Double-armed spring- loaded levers 63 pivoted on pins 62 at the end of the ducts 61 are actuated by the press ram to feed a blank from the duct into one of the magazine recesses. The stripper rings 30 are guided into the working positions of punches 28 and 29 along an arcuate slideway 66 fixed to the table 23. The stripper ring on the punch not in alignment with the die is clear of the slideway 66 and enters the forked end 67 of a slide 68 which actuated the stripper through linkwork controlled by the cam 69 on the shaft 43, Fig. 2. The ejected pressings are blown through plastic pipes 78 to the next station in the production line. Similar stripping mechanism is provided on both sides of the die for co-operation with punch 28 and 29 respectively.

Filed: 1960-02-11
Abstract: 866,343. Monitoring magnetic records. INTERNATIONAL BUSINESS MACHINES CORPORATION. Feb. 11, 1960 [Feb. 25, 1959], No. 4857/60. Class 40 (2). [Also in Group XIX] A magnetic record 1 made by a head 10 is continuously monitored at the instant of recording by a playback head 12. The signals fed to the recording coil 11 and read by the coil 13 are fed through a pair of gates, 21, 19, switched by a timing arrangement 17, to a compare unit 26 whose output 27-29 governs a control unit 30, which particularly operates to prevent further recording if the record of a previous signal is found to be faulty. Where the signals are digital, the timing pulses fed to the gates are short compared with the recorded signals to prevent time-delay between the signals causing malfunction of the compare unit. In a modification (Fig. 3, not shown), a signal discriminator is included in the output from the read head to eliminate noise and other error signals. The arrangement may also be applied to multi channel apparatus (Fig. 4, not shown).

Title: Improvements in or relating to winding carriers for freshly spun thread of artificial silk
IPC: B65H75/24
Filed: 1934-02-14
Abstract: <PICT:0428320/IV/1> <PICT:0428320/IV/2> An adjustable winding-carrier for freshly spun artificial silk comprises two rigid peripheral edges for laterally confining the coil, which is produced between the edges and on supporting members connecting the edges by a continuous winding operation, the supporting members being adjustable so that the tension on the coil can be reduced, the coil remaining in contact with the peripheral edges so that in the subsequent wet treatment the liquids are compelled to pass exclusively through the coil. Various embodiments are shown of which the following are typical. A spool 1, Fig. 4, is formed of two sections 2 and 3 which engage by means of ears 2<1>.  Section 2 by means of rim 2<11> engages a neck 3<11> on section 3, this neck being provided with a screw thread engaging with a screw sleeve 8 which carries a locking dog 9.  By means of handle 10, the sleeve 8 can be turned to displace the sections so that after winding the silk on the spool as shown in full lines it can be adjusted to the position shown in chain dotted lines to relax the wound coil ready for after treatment.  As shown in Fig. 8 a spool is fitted with supporting members 23, for the silk, which are disposed circumferentially in radial slots 22.  The members 23 are displaced to various positions as, e.g. controlled by stops 31, to allow the coil to relax by turning toothed wheel 26.  As shown in Fig. 17, a spool is fitted with supporting members 64 disposed in slots 68. Springy rings 66, at each end of the spool may be locked in the position as shown or relaxed to allow the wound coil to shrink against the yielding pressure of the rings.

Title: Improvements in or relating to traps for animals
IPC: A01M23/26
Filed: 1954-02-19
Abstract: 740,032. Animal traps. WOOLLARD, A. E., and DEAL, W. Feb. 19, 1954, No. 4954/54. Class 5 (1). An animal trap comprises a pair of jaws pivotally mounted so as to lie parallel to a base bar when set, but when released to swing upward under the action of a spring, each jaw carrying a pair of arms which first move to a substantially vertical position and then swing in a direction at right angles to the former movement to cross over the arms of the other jaw to trap and kill the animal. The device comprises a base 19 to which are secured two pairs of uprights 17, 18, the upper ends of the uprights 18 being rounded. Pivoted on pins 14 in the uprights 17 are arms 7<SP>1</SP>, 8<SP>1</SP> connected by cross-pieces 7, 8 constituting a pair of jaws. Rotatably mounted in apertures in the crosspieces are rods 1, 2 3, 4 having their outer ends bent at right angles so that they can lie parallel to the cross pieces. The inner ends 5 are also bent at right angles so that they can extend over the top of the walls 18. A spring 23 secured to the base 19 has an aperture 24 adapted to embrace one pair of arms 7<SP>1</SP>, 8<SP>1</SP>, the arms being held in a position to stress the spring by means of a pivoted catch connected to a platform 21 and engaging the cross piece 8. If an animal steps on the platform, the catch is withdrawn, allowing the spring 23 to close the jaws together. Immediately this occurs, the ends 5, pressing on the rounded tops of the walls 18, are turned to lift the arms 1, 2, 3, 4 to vertical position, movement past the vertical being prevented by engagement of the ends 5 with the wall 17. The ends are then guided between the walls 17, 18 as the jaws close together so that the arms trap and kill the animal caught between them. The aperture 24 is wider than the combined width of the arms 7<SP>1</SP>, 8<SP>1</SP>, and the adjacent faces of the cross pieces are cut away so as to leave a gap when the trap is sprung so that a bird or dog will not be injured.
