Title: Protective bumpers for motor vehicles including tracked vehicels
IPC: B60R19/02
Filed: 1972-04-07
Abstract: 1445969 Vehicle bumpers MV HINDERKS 9 July 1973 [7 April 1972] 16079/72 Heading B7J A bumper 2 mounted on a vehicle 1 has an upwardly facing surface whose extent from front to rear taken at one cross-section is at least 1À6 times as great as the maximum thickness of the bumper at the same cross-section, measured perpendicularly to said surface. The bumper 2, Fig. 1, which may be formed of bent timber is mounted on a vehicle 1 and shaped in such a way that it deflects air so as to transmit a downwardly directed thrust to the vehicle and hence increase wheel adhesion. The vehicle may be a railway vehicle, Figs. 5-7 (not shown), or other tracked vehicle. As shown in Fig. 8, the bumper 112 is carried by brackets 114 which are connected to support arms 119 by bolts 115 in tapering slots 118, which are distorted upon impact as the bolts are forced along the slots. The support arms 119 each carry flange means 149 which are embedded in compressible material 156 such as rubber in a frusto-conical housing 150, which itself has internal flange means 155 spaced from the flange means 149 by the material 156 so as to absorb energy by movement of the arm 119 within the housing 150 on impact. The flange means 149 and 155 may be helical as shown, or be spaced annular flanges, Fig. 17 (not shown). Housing 150 fits in an outer housing 152 of similar configuration and the latter is stretched to absorb further energy upon impact, the space 153 containing compressible material such as gas or foamed rubber to enhance impact absorption. If the outer housing 152 is also displaced by an impact, it strikes a buffer 160 rubber tipped at 161. Alternatively to a one-piece wooden bumper, the bumper may comprise a main body portion at 245 and a U- shaped secondary portion 221, Fig. 13, the limbs of which engage around shoulders on the main portion to normally retain them as shown. The portion 221 is resilient so that, on impact, it is displaced further on to the main portion, but returns to its original position relative to the main portion when impact loading is removed. In Fig. 13, the main portion comprises an outer metal layer 245 on an extruded plastics internal structure 239, keyed together at 248. Between the end of the main portion and the central part of the U-shape is a space which contains impact-absorbing material such as rubber or gas bags 240, as shown. In another form, Fig. 10 (not shown), the limbs of the U-shape are joined by a tensile membrane (223) and the main body portion (224) is of timber.

Title: Magnetic switching circuit
IPC: H03K3/45
Filed: 1958-05-22
Abstract: 830,111 Circuits employing bi-stable magnetic elements. STANDARD TELEPHONES & CABLES Ltd. May 22, 1958 [May 23, 1957], No. 16428/58. Class 40 (9). In a circuit for detecting the remanent state of a core 6 with a rectangular hysteresis characteristic, a clock pulse 20 consisting of negative (- 50 v.) and positive (+200 v.) components has the positive component 22 applied to a utilization circuit 19 in opposition to a negative bias 17 ( - 50 v.) of lower value only when the core is in a first remanent state. The clock pulse is applied to a winding 13 from a source 20 over rectifiers 14 and 15 at the same time as a pedestal pulse 21 (+30 v.) from a source 7 passes through a winding 8, the pedestal pulse driving the core, if in its first remanent state, from remanence to saturation so that the positive component 22 of the clock pulse is entirely unimpeded by the winding 13. The core may be reset to its other remanent state by an inhibiting pulse in a winding 11 and no output is obtained in this case due to the high impedance of winding 13, the combined effects of the clock and pedestal pulses being insufficient to reverse the core state. The negative bias 17 and the negative component of the clock pulse are provided for the purpose of suppressing spurious induced voltages, while resistors 16 and 18 limit the clock pulse current.

[Class 40 (v)] The invention relates to methods of suppressing spurious oscillations and undesired feed-back effects in thermionic high or intermediate frequency amplifiers or oscillator stages, particularly applicable to television amplifiers. According to one feature, the decoupling condensers 3, 4, 5, Fig. 1, for the control grid, anode and screen grid circuits, and associated with corresponding decoupling resistances 11, 12, 13, 14, are returned to the cathode lead of the corresponding valve, this lead being connected to the amplifier earth system 6 over large blocking condensers 7. Chokes 8 are also connected in each valve stage in the H.T. negative lead. Interference from the heater supply circuit 15, 16, is prevented by series chokes 17, 18, and earthing condensers 19, 20. In addition, stabilizing resistances 23 of low value, (e.g. 500 ohms) compared with the anode circuit impedance of the valve and connected close to the valve anode as shown in Fig. 2, 25 being an insulating tube and 25<1>, 26 a rubber covered screening tube which is earthed. Figs. 3 and 3a show a method of connecting an ultra-short wave receiving aerial 28 to a hexode oscillator detector 30. The lead-in 44 is taken through an earthed screening tube 45 to a metal rod 43, which with the sleeve 38 constitutes a condenser of about 1 cm. capacity shown at 29 in Fig. 3a which is a circuit diagram embodying the arrangement of Fig. 3. The local oscillation circuit 31, 32 is manually tuned, the intermediate frequency circuit being connected to lead 33, while the aerial input is not tuned, the choke 36 and condenser 29 rendering this unnecessary. To reduce earth capacities to a minimum, choke 36 is mounted in an insulating tube 37 fitted on the valve cap 39 by a sleeve 39. A screening tube 40 surrounds the connection 41.
