Title: Improvements in and connected with dynamo electric driving sets such as are used for motor propelled vehicles
IPC: B60L50/11
Filed: 1923-07-28
Abstract: 201,571. Porsche, F. July 29, 1922, [Convention date]. Dynamos, driving and regulating; electromagnetic clutches.- An electric power transmission set for propelling vehicles comprises a dynamo having a rotatable field frame coupled to an internal-combustion engine shaft and having its armature coupled to the armature of a motor, the field frame of which is stationary. The shaft on which both armatures are mounted has a lost motion drive on the load shaft and the take-up serves to alter the air gaps of the machines with alterations of load. Acceleration is obtained by varying resistance in parallel with the field windings of the machines. When maximum speed has been attained the dynamo is caused to act as a clutch and the motor as a generator for charging a battery connected to lighting and ignition circuits. For braking, the machines interchange functions. All necessary changes are effected by manipulation of an electric controller in which different movements of a single handle actuate two groups of circuit-changing contacts, and a rheostat and disconnecting switch. Fig. 1 shows the dynamo field frame 2 coupled to the engine shaft 1, the dynamo armature 3 and motor armature 5 fast on a hollow shaft 4, the stationary motor field 6, and the load shaft 10. At starting or any change of torque, cam slots 13. in the hollow shaft 4 slide over roller-ends of a cross-arm 11, Fig. 2, on the shaft 10, so as to alter the compression of a spring 15 and displace both armatures axially, thus varying the air gaps across cone-shaped magnetic parts. Fig. 4 shows the electric circuit connections between the dynamo armature D and field 55, the motor armature M and field 69, circuitchanging contacts 87, 85, 74, 72, 53, 65, traversed by brushes 25, field-rheostat switch 77, and storage battery A.

Abstract: 1,217,556. Automatic exchange systems. INTERNATIONAL STANDARD ELECTRIC CORP. 25 April, 1968 [28 April, 1967], No. 19531/68. Heading H4K. In a system having a fault detection arrangement which identifies all the unknown components in a connection by injecting a special signal into a known component so that it traverses one wire of the connection whereby the appearance of the signal at the unknown components serves to identify these, the arrangement is modified so that it can be used for identifying the components without setting-off any alarms. Under fault conditions the identification is effected automatically and the results recorded intermediately on a fault-relay-contact-tree prior to their transfer to an e.g. lamp panel. When it is required to identify the components of a connection the fault contact-tree is disabled and an alternative contact-tree is connected in its place and, the special signal is injected into a known component e.g. a junctor under the control of a keyboard.

Title: Warp stop motions for looms
IPC: D03D51/28
Filed: 1927-07-23
Abstract: 296,523. Carver Textile Patents, Ltd., and Carver, T. A. B. July 23, 1927. Stop-motions, warp.-The loom handle A is normally prevented from being pushed by a spring-actuated lever 1 into the off position by an armature 5 attracted to an electromagnet 6 which is constantly energized by a winding K in circuit with mains S. A reverse winding J on the electromagnet is normally in a circuit interrupted at 8 by the attraction of an armature L to an electromagnet 9 having a winding 10 fed from the low tension secondary of a transformer PO. When a warp thread breaks, the corresponding detector closes a circuit at X including a neutralizing winding 10, whereby the armature L is allowed to make contact with the part, 8 to allow current to pass through the coil J. The armature 5 is thus released from the magnet 6, and the spring 3 moves the plunger 2 to move the handle A into the off position to stop the loom.
