Title: Improvements in and relating to dynamo-electric machines
IPC: H02K17/38
Filed: 1920-06-19
Abstract: 145,468. Siemens - Schuckertwerke. Nov. 10, 1914, [Convention date]. Alternating-current motors.-The energy from a polyphase supply circuit is supplied to the inducing windings of a slip-ring induction motor and a commutator motor having adjustable brushes, the two machines being mechanically coupled together and having their induced windings connected in series with each other. Fig. 1 shows the connexions for one phase of a threephase commutator motor a, the stator winding c of which is connected to a set of brushes c, d and in series with one phase f, g of the rotor winding of the induction motor b, while the rotor slip-ring of the motor a and the stator winding h of the motor b are joined in parallel to the supply circuit i. The windings, which are connected in series, may be linked together by transformer action, and the induced winding of the motor b may be on the stator, in which case the supply energy is conducted to the inducing-windings through slip-rings common to the two motors. The commutator motor alone may be placed in circuit at starting, and spewed regulation may be effected by varying the field strength of the asynchronous machine. Alternatively, rough speed regulation may be obtained by varying the effective number of windings, while fine regulation is given by rocking the brushes. The rotor winding of the commutator motor may be joined to intermediate tappings on the inducing-winding of the induction motor, as shown in Fig. 4.
Patent GB-166561-A (GB)
Abstract: 166,561. Daimler-Motoren-Ges. July 20, 1920, [Convention date]. Measuring-apparatus.-A circulation indicator and a pressure indicator for a lubricating system are combined in a common casing in such a manner that the oil issuing from the circulation indicator acts directly on the pressure indicator. The casing 1, Figs. 1 and 2, has arcuate cylinders 2, 3 enclosing spring-pressed pistons 4, 5 having conical apertures 8<a>, 9<a> into which extend arms 8, 9 fixed to spindles 10, 11 provided with pointers 13, 14 respectively. Oil enters through a passage 21 into the space at the top of the piston 21 into the space at the top of the piston 4 and displaces the piston to uncover a passage 22 communicating with the central space 24 of the casing, which is leaves through a passage 27. The movement of the pointer 13 on the dial 12 caused by this movement of the piston 4 gives an indication of the quantity of circulating oil. The oil in the space 24 acts on the top of the piston 5 through a passage 25, the movement of the piston being communicated to the pointer 14, which indicates the pressure of the oil. The space at the back of the piston 5, containing the spring, is connected by an aperture 26 to the atmosphere or to a space wherein the pressure is below atmospheric. The spindles are formed with conical portions 15, 16 which are pressed by springs 17, 18 into cavities in the plate 1<a> of the casing. Conical discs 19, 20 are fixed to the spindles between the plate 1<a> and the dial 12 to prevent oil from reaching the dial. At their upper ends, the pistons are provided with lugs 4a, 5a to prevent the pistons from closing the passages 21, 25 respectively. In a modification, the casing is provided with two parallel cylinders 29, 30, Fig. 3, the pistons of which are each engaged by one arm of double-armed levers 33, 34 fixed to the spindles, the other arm of each lever being connected to the casing by a spring.

Title: Improvements in or relating to supervisory devices for radio communication apparatus
IPC: H03F1/54
Filed: 1945-07-02
Abstract: 605,464. Monitoring radio apparatus. PATELHOLD PATENTVERWERTUNGS- & ELEKTRO-HOLDING AKT.-GES. July 2, 1945, No. 16812. Convention date, July 1, 1944. [Classes 40 (v) and 40 (vi)] A monitoring arrangement for radio transmitters, comprises means, including a differential relay for comparing a control signal with a signal derived from the output of the apparatus. As arranged for tone-modulated C.W. telegraphy, a part of the energy from the transmitter aerial 33 is supplied over the cable 4 and transformer 5 to a full-wave rectifier 6. The rectified D.C. produced flows through windings 7, 30 of the differential relays 8, 29, respectively, the demodulated tone frequency appearing across the resistance 21 and being applied to the stage 25 for amplification. The valve 25 is coupled by the transformer 26 to the rectifier 27 which is in series with the winding 28 of the relay 29. The balancing winding 10 of the relay 8 is connected in the anode circuit of the valve 13 which includes the current-adjusting resistance 14. The means for keying the transmitter is arranged to vary the grid potential of the valve 13 also so that in normal operation the relay 8 remains unenergized. Upon a failure of the carrier, keying causes the winding 8 alone to be energized, closing the alarm contacts 9. If the tone modulation fails, the winding 28 of the relay 29 is not energized, so that alarm contacts 31 are closed by the energization of the winding 30. A loud-speaker 32 may be provided to give audible indication of the presence of the tone modulation, and the winding 30 may as an alternative be connected in series with the winding 10 of the relay 8, instead of the winding 7. The arrangement may be simplified for use with a transmitter of unmodulated C.W. telegraphy, (Fig. 2, not shown), by omission of the components associated with the tone modulation. As modified for telephony, (Fig. 4, not shown), the winding 30 of the relay 29 is supplied with rectified energy derived from the modulating signals. According to the Specification as open to inspection under Sect. 91, the differential relays may be replaced by other devices operable by current differences. This subjectmatter does not appear in the Specification as accepted.

Abstract: 940,335. Shovelling machines. P. J. T. ALLARD. May 2, 1962 [May 8, 1961], No. 16900/62. Heading E1F. In an overthrow shovelling mechanism a jack unit 8 acts on a first arm structure 4 to cause the structure 4 to swing vertically about a horizontal axis 3 through the attachment of the structure to a frame 1 that is secured to or incorporated in a self propelled chassis. The arm structure in moving abuts and also swings vertically a second shovel-carrying arm structure 5 that is also secured to the frame about a horizontal axis that is, preferably, coincident with the first axis. A second jack system 10 is mounted on the first arm structure to act on the second arm structure to cause further vertical swinging of said structure when the first jack system has caused a predetermined swinging of the first arm structure by the two jack systems by the end of the predetermined swinging of the second arm structure by the second jack system causes the structure to swing away from the second jack system to abut against a stop 1a on the frame so that the contents of the shovel are ejected rearwards of the mechanism. Preferably the two jack systems each comprise two jacks, all the jacks being supplied from a common source of fluid under pressure. The cross sectional areas of the first pair of jacks is larger than that of the second pair of jacks so that these latter jacks do not become operative until expansion of the first jacks has been completed, the second jacks then expanding at a greater rate than the first jacks. The expansion rate of the second jacks is further increased by pressure fluid being made available from an accumulator associated with the fluid system of the mechanism. The second arm structure is returned from the discharge position by gravity to abut the first arm structure which is retracted by a double acting jack system.
