Abstract: 1311904 Impulse transmitters A P HERNANDEZ 29 May 1970 26113/70 Heading H4K A repertory dialler includes a plurality of discs 6 each having secured thereto a plurality of segmental elements 7 some of which have teeth around their outer periphery which correspond to a particular digit of a telephone number and on rotation of the disc operate arm 12 of microswitch 9 to produce dial pulses. The elements 7 are secured in grooves in disc 6 by means of flexible discs 5 which have a rim 20 which fits in a groove in element 7. The microswitch 9 is carried on a cursor 10 which can be slid along bar 11 to be aligned with a particular disc. Cursor 10 has a finger 13 which contacts rim 25 of the elements and rotates bar 11 against a spring to move arm 44 which operates contacts 43. In operation motor 4 is started by closing manually operated key 39 and maintained running by closure of contact 38 when disc 34 rotates. Rotation of the discs causes finger 13 to ride up from the rest position shown on to surface 25 and thus move arm 44 to mid-position where contacts 51, 53 and 54, 55 are closed to short-circuit handset 49 and insert resistor 50 in circuit. Microswitch 9 is operated to transmit impulses to the line corresponding to the number of teeth 26. When a preliminary code is required to seize a line and further dialling is delayed until dial tone is received a special element 48 is used after the code digit elements. Element 48 causes finger 13 to be displaced further to close contacts 54, 56, thereby short-circuiting resistor 50 and reconnecting the handset and to open contacts 42 to stop the motor. A pilot light 62 indicates when the machine is operating.

Abstract: 1320085 Roller skates A MACHATSCH 7 Sept 1971 41585/71 Heading A6D In a roller skate the axles 6 for the rollers (74) (Fig. 1, not shown) are integral with a carrier 8, one arm 30 of the carrier being pivotally located in a support 38 on the sole plate 2 while the other arm 32 is connected to one end of a 'U'-shaped spring 10, the other end of the spring 10 also being secured to the sole plate 2. As shown the carrier arm 32 and spring 10 are joined by screw 14 and nut 18, a rubber buffer 12 being included. The stiffness of the spring 10 may be altered by the inclusion of replaceable spring inserts (70) on the inside of the 'U' (Fig. 5, not shown). Preloading of the spring may be achieved by screw 20 which locates in a depression 68 in one arm of the spring 10 and which screws into a tapped bore in screw 14, access to a slot 46 being through the said tapped bore. Alternatively the screw 20 may be screwed directly into branch 36 of the spring 10. In a further alternative (Fig. 6) the bracket 40, for weights or stoppers, is a separate part and is interconnected with carrier arm 30 by screw 72. Tightening of the screw causes preloading of spring 10 via the carrier. The spring may be attached to the sole plate by adhesive and/or by screws, but is preferably detachable and adjustable in the longitudinal direction of the sole plate, the latter having longitudinal edges 28 for lateral location of the carrier and spring. As shown, the spring 10, carrier support 38 and bracket 40 are integral but they may alternatively be separate parts. The components are preferably made of sole plate 2 is therefore provided with disc glass fibre reinforced plastics material and the inserts 54, 56 to distribute the loads imposed thereon by the carrier 8 and adjusting screws 20 (when used). The slight separation of the screw head 44 and plate 54 allows limited flexing of the spring but prevents overstressing. The wheels are retained on the axle 6 by circlips located in grooves 42 (Fig. 2, not shown).

Filed: 1971-07-30
Abstract: 1353490 Control of D.C. motors TOYO KOGYO CO Ltd 30 July 1971 36002/71 Heading H2J The control system of an electric vehicle having a D.C. motor with armature 1 and field winding 1a and batteries 2-5 interconnected by diodes 9-14, comprises a circuit breaker 17 which is respectively closed and opened during the driving and decelerating conditions of the vehicle, a changeover switch whose movable contact 20 respectively engages fixed contacts 20a and 20b during the driving and decelerating conditions, a braking resistor 21, a starting resistor 18 controlled by a switch 19 and switches 6, 7, 8 controlling the batteries 2-5. In the driving condition, five speeds are obtained by starting with all the switches 6, 7, 8, 19 open, Fig. 2a (not shown), and then successively closing them in a predetermined sequence, Figs. 2b-2e (not shown), whereby the voltage applied to the motor is increased in steps. Further speed control may be obtained by altering the ratio of a change speed gear of the vehicle. In the decelerating condition, all the switches 6, 7, 8, 19 are opened and the motor is braked by a combined regenerative and dynamic effect, the former occurring when the motor generated EMF exceeds the voltage of the batteries which are charged through the diode 15 and which produce a constant voltage across circuit members 1a, 18, so that the motor operates as an externally excited shunt generator, Fig. 4 (not shown). When the motor speed falls below a certain value corresponding to a generated EMF below the battery voltage, the braking becomes entirely dynamic through circuit members 18, 21, 1a and the diode 16 which has hitherto carried the combined regenerative and dynamic braking current. The motor then functions as a series generator. Typical speed/ current characteristics are discussed, Fig. 5 (not shown), to explain the braking operation. Further characteristics relating vehicle speed to braking force during the regenerative braking action, Fig. 6 (not shown), are discussed to explain how the ratio of the change speed gear is altered at progressively lower vehicle speeds to vary the braking current between an upper and a lower limit. Switches 6, 7, 8 and diodes 10, 12, 14 may be replaced by three changeover switches connected between the batteries 2-5, Fig. 8 (not shown).
