Title: Improvements in or relating to interlocking systems for railways
IPC: B61L5/06
Filed: 1927-10-03
Abstract: 278,706. General Railway Signal Co., (Assignees of Henry, W. S.). Oct. 5, 1926, [Convention date]. Interlocking.-In an interlocking system which includes a traffic controlling device operated by an electric motor, a lever controlling, the circuits to the motor and an indicator showing the condition of the traffic-controlling device, and in which the motor, after completing an operating stroke of the traffic controlling device, is snubbed or braked by generating current in a closed circuit, the indicating circuit is opened by the operation of the lever and maintained open until the snubbing current energizes a relay. The traffic-controlling device may be any such device as a signal, switch-machine, a power-operated derail or point-frog. The control-lever may control two traffic controlling devices and the indication circuit may be so arranged as to be completed only when both these devices have completed their movement and the snubbing current has energized two separate relays. Fig. 1 shows an arrangement of apparatus comprising one lever L controlling the two sets of points of a cross-over road CO each operated by a switchmachine SM', SM<2> driven by an electric motor M<1>, M<2> each supplied by a separate circuit and having its own indicator circuit, including a contact 62 which is closed only when the points are in an extreme position and an indication relay IR<1>, IR<2>, and a lamp P<1>, P<2> which are alternatively put in the circuit bv the contacts 27<1>, 27<2> of the relays D<1>, D<2> which are energized by the snubbing current. In the device shown in Fig. 1, the contacts 27<1>, 27<2> are opened at each stroke of the lever L by the projections on the rod 25 which is moved downwards against the spring 26 lay the cam surface on the slide. Alternatively the circuit of the relays IR', IR<2> may be opened by an electromagnet inserted in the motor circuit so as to be energized at every operation of the motor. The resistance of this magnet is so high that with it in series, the motor does not operate; on energization of the magnet, the armature shunts the coil and the motor then operates. The switch machines are preferably of the kind described in Specification 169,795 and the line wires are provided with cross protection relays CPR', CPR<2> of known construction, for presenting operation of the apparatus by stray currents, connected in series with relays D', D<2>. The lever L is controlled by a lock-magnet LM controlled by one or a series of relays dependent upon conflicting traffic-controlling devices. Relays IR<1>, IR<2> similarly control other devices such as the signal levers for the main and diverging roads at the cross-over junction.

Abstract: 1,203,663. Endless conveyers; feeding cigarettes. AMERICAN MACHINE & FOUNDRY CO. 31 May, 1968 [7 July, 1967], No. 26220/68. Headings B8A and B8S.  An automatic feeding device for rod-like articles S for use in a packaging machine having an endless conveyer' on which is carried a plurality of containers 8 for receiving the articles and a hopper having a plurality of serially arranged channels 11, for distributing a plurality of said articles to the container, comprises means 65 mounted at the end of each of the channels for removably supporting the articles thereon and means 68 mounted on each of the containers for removing an article from each of the support means 68 and causing it to drop into the container 8 as it moves past the channel. As shown, each container 8 has three compartments 108, 208, 308, which are successively filled by three respective series (110), (210), (310); (Fig. 1A and 1B, not shown) of channels 11. As a given container 8 proceeds under the channels 11 of the first series (110), a slidable cage 57 has a cover 157 which has an opening positioned above the leading container compartment, i.e. 108. As the compartment 108 passes beneath the first of the channels 11 of the series (110), four laterally spaced members 68 push the lowest cigarette from the support 65, off from the latter and into the channel (Figs. 3, 4 and 5). The arms 68 co-operate with a stop member 71 carried by a spring 72. The latter permits the member 71 to pass under the support 65 (Fig. 3) and rise again to operative position (Fig. 4). The support 65 has a guide surface 66 for guiding the cigarette being fed from the previous support 65 (Fig. 5). A cigarette is fed in this way into the compartment 108 from each successive channel 11 of the series (110) as the container 8 passes beneath them. As the container 8 moves towards the series (210) a cam follower roller 61 on a bell crank 359, 59, connected to the cage 57, at 259, moves down a sloping section of a cam 74. This causes the cage to move rearwardly and position the inlet opening above the second compartment 208. In this way the second compartments 208 of the containers are successively filled as they pass under the channels 11 of the series (210). Similarly the third compartments 308 are filled under the channels of the series (310). The bottoms of each of the compartments of each container are formed by respective plungers 52, each of which is on a stem 53. At the bottom of the latter is a cam follower 61. The cam followers 61 corresponding to the plungers 52 of the leading compartment 108, bear on a cam 173 which causes the plungers to lower progressively as the compartments 108 are filled. Similar cams (273) and (373) (Figs. 1A and 1B, not shown) control the plungers of the compartments 208 and 308. The cigarettes may be retained on the supports 65 by the action of a vacuum conduit 67. The pusher members 68 may be lowered (by means not shown) if it is desired to prevent feed from a given series of channels.

Title: Electrical weighing apparatus
IPC: G01G7/00
Filed: 1945-10-09
Abstract: 601,083. Electric weighing-apparatus. GROOT, M. J. DE. Oct. 9, 1945, No. 26335. Convention date, June 14, 1941. [Class 143] [Also in Group XXXVIII] A conductor supported in a magnetic or electric field is tensioned by a weight to be measured, and a current passed through the wire to deflect it in the field. The weight is then measured either by the deflection produced by a predetermined current or by the current or voltage needed to produce a predetermined deflection. Fig. 1 shows the conductor wire 1 supported between the poles 4, 5, of a permanent or electromagnet. Deflection of the wire is observed by means of a light source 8, and aligned optical projection systems 6, 7 located inside the poles 4, 5, which project an image of the wire on to a screen 9. The weight to be measured is suspended from the wire at 3, but in an alternative arrangement, Fig. 3, (not shown) the wire is supported at its ends in a horizontal position and loaded by the weight at an intermediate point. In this case the weight is measured by the current flow needed in the conductor to annul the deflection produced by the weight. The sensitivity of the arrangement is adjustable by varying the magnetic or electric field. When light objects are being weighed, the wire 1 may consist of a quartz thread covered with gold or other conducting material, and may be mounted in a vacuum together with the means for taking up the load.
