Title: Improvements relating to the control of mixed power installations
IPC: H02P9/00
Filed: 1934-06-19
Abstract: 440,039. Systems for transmitting mechanical power. SACCAGGIO, P. C., El Chalet, Remedios de Escalada, Ferrocarril del Sud, Buenos Aires. June 19, 1934, No. 18148. [Class 38 (iv)] [See also Group XXXVII] In a system in which traction motors 18 are supplied from a generator 2 driven by a primemover, and in which the generator field regulator 1 is operated by hydraulic or pneumatic means 3 automatically controlled by load sensitive means, further automatic control means for the regulator operating means are provided responsive to the vehicle speed and effective, when the speed attains a predeter mined value, to arrest the movement of the regulator. The regulator operating means 3 is controlled by valves 5 and 7, operated respectively by a governor 6, which may be the governor controlling the engine speed and an electromagnet 9 controlled by a switch 8, as described in Specification 403,680. Ir parallel with the contacts of the push-buttor switch 8 are the contacts of relays 17 carrying the motor armature currents, so that the valve 7 is operated to stop accelerating move ment of the regulator 1, when the armature current of a motor reaches a certain value The operating means 3 is further controlled by a valve 12 biassed by a spring 15 to a position in which the regulator 1 is returned to its initial position, but operated against the spring by an electromagnet 13 controlled by a switch 14, to cause accelerating movement of the regulator. The circuit of the electromagnet 13 also includes the contacts of a relay 28 energized when a speed-responsive device 23 registers a speed exceeding a predetermined value. The device 23 also closes the circuit of the electromagnet 9 at a certain lower predetermined speed. Thus, when the speed reaches a certain value, the electromagnet 9 is energized and further operation of the regulator is prevented. If the speed rises further the electromagnet 13 is de-energized so that the regulator returns quickly to its initial position. The speed-responsive device comprises a tube 23 partially filled with mercury, operated through a rack 21 and pinion 21<1> from a speedometer 20 and having contacts 25, 26, 27 projecting therein whereby the circuits for the relay 28 and the electromagnet 9 are made. The speeds at which these circuits are completed may be adjusted by means of a handle 34 having a threaded spindle co-operating with a sliding carrier for the tube 23 and pinion 21<1>, the tube being rotated and moving along the rack. The carrier for the tube 23 has a pointer co-operating with a scale. The speed-responsive device may alternatively comprise a contact corresponding to the contact 25, movable with the speedometer and cooperating with two adjustable sliding contacts. The relay 28 may be energized. to break the circuit of the electromagnet 13 by means of contacts 37, in response to excessive loading of the prime-mover as described in Specification 403,680.

Title: Improvements in or relating to the fabrication of packing tubes of thermoplastic material
IPC: B29C43/34
Filed: 1960-05-26
Abstract: 918,140. Moulding packing tubes. HAUF, L. May 26, 1960 [May 28, 1959], No. 18661/60. Class 87(2). Packing tubes of thermoplastic material are made by mounting a prefabricated tubular body 4 over a mandrel 3, introducing a measured quantity of the material which has been rendered plastic by heating into the cavity 5 of the die 1 through the central nozzle 2 while or before the mandrel 3 is advanced into the cavity 5 so as to mould a head on to the adjacent rim 4a of the tubular body 4. Descent of mandrel 3 and the feeding of the material are effected so as to limit cooling of the material before it contacts the die and mandrel. A peripheral recess 6 is formed between the rim 4a and the adjacent mandrel 3 in order that the welding of the tube head to the body 4 is effected along a substantial length of the body. When the thermoplastic material is polyvinyl chloride, die 1 and mandrel 3 may advantageously be used as electrodes of a highfrequency heating device. This heating assists in the welding of the head to the rim 4a and may, if required, be used during the moulding of the head to compensate for the heat loss of the material when it contacts the die and mandrel. The process may also be used for the moulding of bottoms, for example flat bottoms, on packing tubes.
