Title: Wheel rims
IPC: B21D53/30
Filed: 1954-03-29
Abstract: 754,250. Wheel-building apparatus; wheel rims for pneumatic tyres. WINGFOOT CORPORATION. March 29, 1954 [Nov. 23, 1953], No. 9071/54. Classes 144 (1) and 144 (2). [Also in Group XXII] A one-piece rim for mounting a tubeless pneumatic tyre and having one edge portion shaped to include tyre bead mounting means such as the bead seating 4, Fig. 1, and the bead retaining flange 6 and a rim mounting surface 11 with a closed cavity between the seating 4 and mounting surface 11, is formed from a one-piece cylindrical band, e.g. as produced by buttwelding together the ends of a blank sheet, by applying pressure to one edge of the band in an axial direction, as in a high-pressure platen press, to force the opposite edge into engagement with forming means such as a U-shaped cavity 25, Fig. 5, in the upper die 23 to cure first outwardly and then axially toward the said one edge of the blank in spaced relation to the band and subsequently applying pressure to the undeformed said one edge in an axial direction in a platen press, Fig. 6, to upset the curled edge against a forming die to form in the curled portion the rim mounting surface 11 extending radially inwardly and to form, at least partially, the bead-retaining flange 6 and the bead seat 4. The curled edge is then further upset against a die, Figs. 7 and 8 (not shown), to complete the retaining flange 6, Fig. 1, and bead seat 4 and to form the portion 15 extending radially inwardly to the inner portion 10 terminating in an axially extending portion 17. The undeformed edge portion of the blank is then expanded in a conical expanding die, Fig. 9 (not shown) to substantially the diameter of the bead seat 4 to form the bead seat 3. The band so shaped is submitted to a first rolling operation, Fig. 10 (not shown), between rolls shaped to form finally the bead-retaining flanges 6 and bead seat 4 and partially form a bead retaining edge 7 on the expanded end portion and then to a second rolling operation, Fig. 11 (not shown), to finally shape the bead retaining flange 7 and seat 3. The shaped band is sized to a predetermined size as by expanding to slightly oversize and then shrinking. The axiallyextending portion 17 supports the bead seat 4 on the portion 10 and is prevented from relative movement thereto as by inter-engaging peripherally-extending ridges in the portions 17 and 10 formed during one of the rolling stages. Alternatively these portions may be secured together by spot or tack welding at intervals. The portion 17 may be omitted and the end of portion 15 tack-welded at intervals to the portion 10. In this case the stage represented by Fig. 6, may be omitted and the curled edge 30, Fig. 5, shaped in the succeeding stage as the second operation to form the rim mounting portion 11 and partially form the bead seatings 4 and bead retaining flange 6 to be completed in the rolling stage.

Title: Improvements in or relating to automatic signalling systems
IPC: H04Q3/00
Filed: 1956-03-23
Abstract: 787,945. Automatic exchange systems; non-contact-making relays. PHILIPS ELECTRICAL INDUSTRIES, Ltd. March 23, 1956 [March 28, 1955], No. 9136/56. Class 40 (4). A line identifying arrangement in an automatic exchange system in which subscriber's lines in a group are distinguished by their first and second digits comprises a matrix MS of saturable magnetic cores, each core being associated with a particular subscriber's line. The cores are arranged in columns representing the first digit and in rows representing the second digit, and are normally pre-saturated by direct current applied to column windings LV over leads V1, V2-Vm and resistors RV1, RV2-RVm. When a call is initiated by a subscriber AB looping line wires S1, S2, a demagnetizing current passes over resistors R1, R2 and R21 to a winding LA on the core associated with the calling line. The columns of cores are subjected in turn to recurring pulses which are sequentially applied in different time positions from a multiphase generator MP over leads V1, V2-Vm to the column windings. As the core associated with the calling line is unsaturated, those pulses which arise periodically in the appropriate column lead are induced over the core into a row winding LD and cause an auxiliary core ME1, ME2-MEn to produce corresponding output pulses in its windings LT, LE. The pulses in winding LT operate a common call detector OD which starts a line-finder OZ. When the calling line is found, contact ca closes and restores the associated matrix core to its initial saturated condition by short-circuiting winding LA. Operation of the call detector also closes contacts od1, od2-odn and permits the pulses induced in winding LE of an auxiliary core to fire a gas tube GE1, GE2-GEn in a pulse receiver IR. This operation pulls up an anode relay DE1, DE2-DEn and identifies the second digit of the calling line. Due to the provision of a common cathode resistor RKE, the remaining tubes are disabled and a further group of gas tubes GT1, GT2-GTm are brought into an operative condition for identifying the first digit. As each tube GT is separately associated with a pulse generator lead V1, V2-Vm, a particular tube is fired by that pulse which acts in the column lead connected with the calling line core and causes the second digit portion of the pulse receiver to operate as previously described. The first digit is registered by an anode relay DT1, DT2-DTm and the remaining tubes are disabled by a common cathode resistor RKT. A contact cs is opened when it is required to extinguish the gas tubes and restore the pulse receiver to its initial condition.

IPC: F16D41/26
Filed: 1918-06-11
Abstract: 116,718. Henry, G. June 9, 1917, [Convention date]. Free-wheel arrangements.- In means whereby, without the rider descending, the freewheel clutch of a cycle may be changed into a fixed-wheel drive, a controllable cone clutch is fitted between the loose outer chain ring and the part of the free-wheel clutch fixed to the road-wheel hub. The controllable clutch comprises an internally-coned part a upon the ring a<1> and a slidable coned ring b upon the bearing-cone a<5> and parts a<2>, a<3> screwed upon the hub. A disk d connected bv studs to the chain ring is screwed upon the sleeve c of a disk f, which is screwed upon the sleeve e<1> of an inner disk e<2>, and the disk f can be held against rotation by a catch h<2> with teeth f<1> or f<2>. As shown in Figs. 1 and 3, the free-wheel clutch is operative, and, as the disk f turns with the disk d, the teeth f<1> depress the catch h<2> and the tooth f<2> cleans it. If, however, the rider back-pedals, a tooth f<1> comes into contact with the catch and the disk f is prevented from turning; in consequence, the disk d screws inwards upon the sleeve e and forces the ring b into engagement with the part a, so that, when forward-pedalling is resumed, a fixedwheel drive is obtained. In order again to have the free-wheel clutch in action, the catch is raised by hand control into the path of the tooth f<2> , so that, during forward-pedalling, the disk f is prevented from turning and consequently the disk d screws back to the position shown in Fig. 1. To prevent the catch from holding the disk f longer than is necessary for the disk J to screw back tc normal position, the disk d is formed as an eccentric so mounted that, when in its outermost position, the portion d<2> of largest radius contacts with a shoulder h<8> on the catch and moves it out from engagement with the tooth f<2>. A spring h<3> disposed between the front clip h<1> and a lug h<4> on the catch is provided to absorb shock when one of the teeth f<1> engages with the catch on back-pedalling.

Abstract: 760,834. Pulse generating circuits. BRITISH THOMSON-HOUSTON CO., Ltd. March 3t, 1955 [April 1, 1954], No. 9615/54. Class 40(6) A pulse generating circuit comprises a normally conducting control valve and a normally non-conducting pulse generator valve which are connected in a flip-flop type circuit so that when a trigger pulse is applied the control valve is cut-off and the pulse generator valve conducts until after a period determined by a resonant circuit it is cut-off by the control valve conducting again. The Figure shows a circuit for generating pulses having a duration determined by the period of resonant circuit LCI. Control valve V2 is normally conducting and pulse generator valve V1 cut-off. When a positive trigger pulse is applied at terminal A valve V2 is cut-off at its cathode and V1 starts to conduct; resonant circuit LC1 "rings " due to the applied trigger pulse and when the grid potential of valve V2 has risen sufficiently due to the " ring- ing" voltage V2 conducts and V1 is cut-off. Thus the output pulse generated at the anode of V1 has a duration determined by the period during which V1 is conducting which is one quarter of the period of resonant circuit LC1.
