Title: Telecommunications systems
IPC: H04M11/06
Filed: 1974-04-16
Abstract: 1466162 Automatic exchange systems SIEMENS AG 16 April 1974 [19 April 1973] 16488/74 Heading H4K In a telecommunication system in which substations can operate in two communication modes (e.g. speech or data) depending on the state of a switch-over device therein, each substation is equipped with an operating mode switch to select between manual and automatic switch-over and the system is such that after a suitable connection set is taken into use, the set transmits a signal to the called subscriber station requesting it to switch-over to the second transmission mode, on receiving an acknowledgement that the latter has been effected transmits a switch-over request to the calling subscriber station and upon receipt of an acknowledgement that this has been effected transmits a signal to both substations indicating that the communication in the second mode can begin. The figure shows one substation. If a calling subscriber by dialling a preselection digit indicates that a data connection is required, a path to the wanted subscriber is set up via a universal connection set (Fig. 3, not shown). When the path is complete the common control signals the connection set which isolates the called subscriber line and applies a +ve pulse to the b wire. Relays TR and JB responds to the pulse and its end respectively. Contacts of relay TR disconnect the telephone instrument FA. If the operating mode switch BS in the called substation is set to the automatic position as shown relay TR is maintained and relay TB via its contact 2ib enables the switchover relay U which connects the data units DE, DUE to line via a resistor R. A detector relay in the connection set responds causing a tone to be coupled to the calling line, that line to be isolated and a positive potential connected to the a wire. If the operating mode switch BS at the calling station is set to automatic mode relays TR and JA respond coupling the data set to line automatically while if the switch BS is set to manual mode the caller on hearing the tone must operate the data switch DT. In either event a further detector relay in the connection set responds causing a direct metallic two wire path to be set up round the connection set with a common potential on both wires. A relay C responds in both substations indicating that data transmission may commence. This common potential is supplied via a detector which responds when either substation signals an end to data transmission by operating a relay BB to break the D.C. path to earth. The call may be continued in speech only mode or be released. If the called subscriber station is set to manual mode no acknowledgement is received therefrom and normal ringing signals inhibited to that moment are supplied to the called station, i.e. an audio connection can be set up and this can be converted to a data connection by use of the data switch DT in the called station during the call.

Title: Percussive-action mechanism
Inventor: KOZLOV LEONID PAVLOVICH
IPC: B25D11/10
Filed: 1965-04-21
Abstract: 1,048,173. Percussive tools. TSENTRALNY NAUCHNO - ISSLEDOVATELSKY I PROEKTNO - KONSTRUKTORSKY INSTITUT PODZEMNOGO I SHAKHNOGO STROITELSTVA. April 21, 1965, No. 16862/65. Heading B4C. A percussive mechanism for use in drills or hammers comprises a body 1 in which a hammer block 2 reciprocates and periodically engages, on its return stroke, with a drive 16, 17 through a clutch 3 moving in a working chamber 5 filled with a liquid, the clutch being connected to an additional chamber 7 housing a resilient element serving to maintain a constant pressure on the liquid in the working chamber through a movable or elastic partition 8 separating the liquid from the resilient element and thus transmitting kinetic energy to the hammer block and actuating the clutch. The hammer block 2 is formed with a head portion 24 adapted to engage within the clutch 3 which is mounted on a shaft 15 connected by a rod 16 to a crank and an electric motor 17. The movable partition 8 is in the form of a piston slidable in a cylinder constituting the chamber 7 and acted upon, on one side, by the oil in the chamber 5 and on the other side, by a pressurized gas fed into a chamber 9. Oil is circulated through the chamber 5 via an inlet 29 and outlet pipe 30 having a valve 31. In operation, when the motor is started, the clutch moves toward the left, as shown, and engages with the head 24 of the hammer, oil in a chamber 25 then being forced through a port 26 and a one-way valve 20 into the chamber 5. When the clutch begins its return stroke, the valve 20 closes so that a reduced pressure develops in the chamber 25 and the hammer is drawn back into the chamber 5. During this movement the displaced oil forces the piston 8 into its cylinder against the pressure of the gas and, after ports 27 in the hammer are uncovered so as to release the clutch, the built-up oil pressure acts on the head 24 to drive the hammer rapidly forward on a working stroke. In modifications, instead of the cylinder 7 being secured externally of the body 1, as shown, it is movably incorporated within the body and rigidly connected to the clutch member. The cylinder is moved by means of a swash-plate drive. The piston 8 may be replaced by a flexible diaphragm and the loading effected by the gas may be replaced by a spring.
