Title: A multiple piston distributive pump with hydraulic system for the synchronized operation of a plurality of working cylinders
IPC: F15B11/22
Filed: 1963-05-14
Abstract: 1,022,577. Hydraulic machines; reciprocating pumps. H. BIERI AND SOHN. May 14, 1963 [May 14, 1962], No. 19165/63. Headings F1A and FIP. The return stroke under load of each of a plurality of hydraulic piston and cylinder units 13, 12 Fig. 1 (not shown) arranged in pairs is effected synchronously by withdrawing measured quantities of hydraulic fluid e.g., oil from the cylinders by a pump having a piston and cylinder unit for each hydraulic unit and which ejects fluid against an elevated pressure. Each pump piston 4 Fig. 2 (not shown) is driven by a plunger 5 actuated by a common eccentric 2 driven by a motor 1 and the stroke is varied by a screw cap 22 bearing on a shoulder 25 of the plunger 5. Outward displacement of a piston 13 against load is effected by fluid forced by associated piston 4 past a non-return valve 7, a blocking valve 8, lines 9, 10 leading to chamber 11 and fluid from the other side of piston 13 is returned through lines 47, 39 a pressureretaining valve 40, a line 20 connected to the delivery side of a low pressure pump 19 and leading to a non-return inlet valve 21 of cylinder 3. A pressure relief valve 30 diverts high pressure fluid through a line 35 to an oil tank 18 and actuates a switch 37 to stop the motor 1. To avoid stopping the pump at high pressures valve 8 is closed and a valve 33 opened whereby pump delivery is diverted past a non- return valve 14 and a pressure-retaining valve 16 to tank 18 and line 10 is connected by valve 33 to a record inlet valve 34. Low pressure pump 19 not only feeds pump cylinder 3 but may extend piston 13 rapidly when under no load when low pressure fluid is directed by a valve 42 through a line 43 and a coupling 44 connected to line 10. To quickly retract piston 13 under no load, low pressure fluid is directed through valve 40 and lines 39, 47.

Abstract: 1,170,573. Automatic exchange systems. SIEMENS A.G. 26 April, 1968 [28 April, 1967], No. 19809/68. Heading H4K. In an exchange system in which some subcribers can obtain special services by dialling a special code, initiation of a request for a special service causes a test connection to be set up to the caller so as to verify his identity-and thereby in effect his class of service-prior to his connection through to the relevant special service junctor. Each such junctor is connected via a jumpering field to the identification wires of those subscribers who are entitled to the service. If the calling subscriber is not reached during the test connection or if his line does not test busy (his handset should still be off-hook), an alarm is operated and he is supplied with a warning tone so that he may attempt the " call " again. If the test is successful, he is informed accordingly by a tone or verbal announcement. The special services are stated to be: call diversion; public address; ; connections to enquiry positions; cancellation of break-in priority (e.g. when he is absent) or cancellation of the video transmission in a TV telephone system.

Title: Differential metering mechanism with pre-selection
IPC: G01D5/12
Filed: 1955-07-08
Abstract: 771,193. Dictating machines. BAR, S. July 8, 1955 [July 8, 1954], No. 19864/55. Class 40 (2). [Also in Group VIII] A differential metering mechanism for dictating machines comprises two switches and two control cams which are mounted with light friction on a common shaft associated with the movement to be checked or measured, and are associated with two dials for operating and recording purposes and fast with the two cams, one of which actuates one switch at the end of the travel, and the other operating the other switch at the end of its travel in the opposite direction. Shaft 1, Fig. 1, is the shaft whose movement is related to an amount of recorded magnetic, or other, tape or wire to be measured. Cams 2, 3 are frictionally mounted thereon, the cam 2 being directly coupled to a disc 11 by a pin 13, and a cam 3 to a dial 12 by a pin 14. During a recording, shaft 1 is driven counterclockwise and the dials and cams are caused to rotate therewith from the position shown in Figs. 3 and 4. At the end of a recording, disc 11 is returned to zero (Fig. 6) and the cam 2 to the dotted position in Fig. 5 leaving the dial 12 in the position shown in Fig. 6 and the cam 3 in the position shown by the full lines in Fig. 5. During a further period of recording, dial 12 and cam 3 are advanced a further angle a. If a rewind switch (not shown) is operated, cam 2 comes into contact with switch 15 to stop the machine and place the first recording in reserve. Further similar operations finally result in cam 3 striking switch 16 and stopping the machine when the recording capacity has been reached. A rewinding for effecting continuous reading of all the texts may then be made by rotating disc 11 until the index marks 18, 19 coincide and the cams 2, 3 are in the position shown in Fig. 7, and then operating the rewind key of the machine, the movement being stopped when cam 2 strikes switch 15. Rewinding may be effected by remote control irrespective of the return of disc 11 by means of a switch (not shown) in parallel with switch 15 and operated by a lug 29 on cam 3 in place of the cam 2 and switch 15.
