Title: Energy absorbing devices
IPC: F16F7/12
Filed: 1969-06-18
Abstract: 1279882 Deformable energy-absorbing devices TOKYU SHARYO SEIZO KK 18 June 1969 [25 June 1968 14 Nov 1968 15 Nov 1968] 5899/72 Divided out of 1279881 Heading F2E An energy-absorbing device comprises a tubular body 1, Fig. 2, having an outwardlyextending portion 8 joined to a tubular portion by a round corner 3, the tubular body 1 being secured to a guide member 9, having an aperture 10 larger than the tubular portion, at the portion 8; the guide member 9 is formed with a rounded corner 11 along the edge of the aperture 10, and is formed of a material and so dimensioned that its rigidity is greater than that of the tubular body 1; the tubular portion of the tubular body 1 is adapted to undergo plastic deformation so as to form a third portion of cross-section intermediate the cross-sections of the tubular portion and the aperture 10, and over-lapping or under-lapping the undeformed part of the tubular portion and the aperture in the guide member 9, upon application of axial compression. As shown in Fig. 3, the tubular portion is progressively rolled inside out through aperture 10. As shown in Figs. 2 and 3, the guide member 9 is formed as an annular plate with a cylindrical portion 12 joined by a rounded corner 11, the thickness t 2  being greater than thickness t 1 . Alternatively, guide member 9 may be so thick as not to need a cylindrical portion 12, (Fig. 4 not shown); or it may be provided with a circular rib surrounding the aperture and directed towards the tubular body, (Fig. 5, not shown), instead of the cylindrical portion. In Fig. 6, (not shown), the round corner 3 is more acute and already protrudes into the aperture 10 (somewhat as phase I of Fig. 3). In Fig. 7 (not shown) the cylindrical portion 12 of the guide member 10 of Fig. 2 is lengthened to form a short tube, and the part perpendicular to the axis is correspondingly reduced in diameter; in Fig. 10 (not shown), the structure of Fig. 7 is modified by adding a reinforcing ring around the angle of the guide member. In Fig. 9 the guide member is formed by a tube of uniform cross-section but the aperture 10 and rounded corner 11 are formed by turning the tube end back on itself; portion 8 of body 1 is bent around the outside of the guide member.

Title: Improved regulator for controlling textile spinning and doubling machines
IPC: D01H1/30
Filed: 1953-03-04
Abstract: 727,847. Speed regulator for spinning spindles. SOC. DES FABRICATIONS UNICUM. March 4, 1953 [March 14, 1952; Jan. 10, 1953], No. 6030/53. Class 120(2). A speed regulator for the spindles of spinning, &c., machines in which use is made of a basic cam actuated by the ratchet shaft of the machine and a cyclic cam actuated by the shaft of the heart-shaped cam of the machine, the movement of these two cams being combined to act upon a rack controlling a member that varies the speed of a spindle driving motor or a variable-speed gear is characterised in that the cyclic cam acts directly upon a simple lever articulated to the rack and in that means are provided whereby the said lever is acted upon by a variable fraction of the periphery of the cyclic cam, the angle subtended by this fraction being a function of the instantaneous position of the basic cam. In the embodiment shown the cyclic cam 1 acts on one end of a lever 3 pivoted at 4, the other end of the lever 3 being articulated at 5 to a rod 6 which forms an extension of the rack 7 so that the rack normally follows the movement of cam 1. The rod 6, however; carries a stop button 13 over which passes a cable 14 on one end of which is a weight 15 and the other end of which is fixed to the rim of the pulley cam 2 which acts as the basic cam and is driven by a worm and wormwheel from the shaft 20 which transmits to it the motion of the ratchet shaft of the machine. The angle of rotation of the cam 2 is limited by an adjustable abutment 16 so that movement of the rod 6 to the left and therefore of the roller 11 to the right is limited when the abutment 16 meets the stop 17 by the length of cable between the abutment 16 and the periphery of the cam 2 this length being a function of the instantaneous position of cam 2. In operation, the cam 2 turning with continuous counter clockwise motion the cable unwinds at first and the amplitude of movement of the rack increases corresponding with the formation of the bottom of a cop on the machine. After the cable has been completely unwound it then winds up on the cam 2 and the amplitude of the rack decreases corresponding with the formation of the top of the cop. If it is desired to have a cylindrical portion between the top and bottom of the cop a releasable connection is provided between the wormwheel 18 and the cam 2 so as to keep the amplitude of movement of the rack constant for a certain length of time.

Filed: 1964-02-19
Abstract: 1,057,832. Photo-electric arrangements. EASTMAN KODAK CO. Feb.19, 1964 [Feb. 20, 1963], No.6857/64. Heading G1A. [Also in Division G2] A photo-electric exposure meter has two photoresponsive elements which accept light from different zones at the subject and whose outputs are fed in opposition to an electro-mechanical transducer in order to compensate for high contrast in the subject-lighting. In Fig. 1, elements 50, 51 are photo-conductive cells receiving light from zones defined by angles α and # respectively and contained in a camera. Batteries 61, 62 are connected in opposed parallel relation with galvanometer 57 whose shaft 68 rotates a diaphragm vane 56 and through extension shaft 69, a side 66 projecting through aperture 70 in viewfinder wall 71. A further photo-conductive cell 63 receiving light from a wide angle is connected across galvanometer 57 and acts as a shunt resistance at high levels of illumination to avoid under exposure of the darker regions. Cell 50 aimed at the central zone is arranged to pass 2¢ to 5 times more current to the galvanometer than cell 51, this being achieved by choice of the battery voltages or by suitable resistance networks. Exposure is therefore largely decided by zone light. Mask 74 ensures that only light from the peripheral zone reaches cell 51. Various patters of and zones are given, and in each case the output from the cell reduces that at the cell. A single battery may be used with a potential dividing circuit, with various shunt resistors to set the sensitivity of galvanometer 57. Photo-voltaic cells in opposition provide opposed voltages across series resistors to deflect the galvanometer in an alternative form. The photo-cells may be mounted on the same support in complementary patterns, or separate cells may be used with beam-splitter systems in the form of semi-silvered inclined mirrors, mirrors with central apertures, or small central inclined mirrors. For artificial or non-uniform illumination, the cell may be masked or disconnected to provide greater sensitivity to the light from the central zone.

Title: Improvements in or relating to pulsed radar systems
Inventor: GRAY TREVOR
IPC: H03K4/20
Filed: 1952-03-17
Abstract: 718,059. Pulse radar. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Jan. 23, 1953 [March 17, 1952], No. 6911/52. Class 40 (7) Relates to pulse radars with a P.P.I. display in which a sawtooth current waveform of adjustable duty ratio, Fig. 1, is generated in the rotor of a magslip whose stators are coupled to the orthogonal deflecting coils of the cathode-ray tube. In such a system the control position of the cathode beam on the screen of the tube corresponds to the mean level ML of the waveform. Hence when the duty ratio is altered the timing of this position relative to the commencement of the sweep changes and consequently a sync pulse for triggering the transmitter and initiating the trace brightening pulse is generated when the sweep intersects the mean level so that origin of the range sweep always occurs at the centre of the screen. According to the present invention this is achieved by using a " magnetic Miller " generator V1 with the rotor L of the magslip in the anode circuit thereof, a negative voltage sawtooth waveform produced across the anode and resistor R2 being R.C. coupled to an amplifier V2 having a cathode load R4 much greater than its anode load R5 and the cathode of V2 being coupled to the cathode of a clamping valve V3 whose grid is connected to an adjustable negative voltage source RV1. V3 is conductive only when the input to V2 is negative with respect to earth and in this condition the cathode potential V2 is clamped so that the anode output from V2 increases suddenly as the tial (i.e. earth) corresponding to the mean level of the current waveform and so sync. pulse is derived from this output. The grid potential of V3 may be adjusted so that the sync. pulse is generated just before the current waveform passes through its mean level. Alternatively the sync. output may be derived from the anode of V3 or differentially between the anodes of V2 and V3 in which case an anode load resistor must be provided for V3.
