Title: Improvements in injection presses
IPC: B29C45/67
Filed: 1951-04-24
Abstract: 706,854. Injection-moulding machines. CAYLA, G. April 24, 1951 [April 24, 1950; Sept. 16, 1950], No. 9584/51. Class 87 (2) The mould halves of an injection-moulding machine are closed by jacks which lock the halves together without subjecting the supporting columns of the machine to additional. stresses. The mould halves 8, 9 and the injection cylinder 5 are mounted on vertically movable platens whilst the injection piston (not shown), is fixed. When the press is fully opened the pistons 35, 36, Fig. 3, lie at the bottom of hydraulic cylinders 34, 37. To close the press, fluid is admitted to the cylinders 34 -via valves 56, 39 and the piston 35 rises rapidly until the mould has been closed and brought into communication with the injection cylinder 5. At the same time, fluid flowing into jacks 60 tends to displace pistons 59, 61 in opposite directions and locks the mould parts. As injection cylinder 5 commences to move over the fixed plunger, pressure increases in the cylinder 34 and the liquid displaces piston 36. Pin 41 now allows the valve 39 to close and the injection stroke is completed under the high pressure exerted by the large-area piston 36. During the injection stroke this high pressure is transmitted to the jacks 60. In an alternative form of the press of Fig. 3, the parting plane of the mould lies in the direction of displacement of the injection cylinder and the jacks lie perpendicularly to this direction. A further alternative is briefly described, in which the injection cylinder is fixed and its plunger movable. In the modified press of Fig. 9. the jacks 60 are four in number and are supplied with fluid from the cylinder 34 via a valve box 72 containing two valves 73, 74 each controlling two of the jacks 60. By means of screws 92, 93 the valves 73, 74 may be raised against their seats and two of the jacks, or all of them put out of action: To open the press, distributer box 90 is manipulated to supply fluid to the upper faces of pistons 35, 36 and also to the lower faces of pistons 87, 88 via the pipe 89. The valves 73, 74 are raised and the jacks 60 connected to the exhaust pipe 85.

Abstract: 1504209 Monitoring AC motors SIEMENS AG 7 March 1975 [8 April 1974] 9713/75 Heading G1U A circuit arrangement for monitoring the speed of each A.C. motor of a multiple motor installation and the determination of the speed of an individual motor by measuring the frequency of the regenerated current when the supply is disconnected and the motor terminals short-circuited is described. Current transformers 22-24 are used in one phase of each motor 2-4 provide a signal f 2  sequentially through a pulse shaper 32 to comparator 21 in angle comparison circuit 19. A reference phase signal f from the motor supply is applied through a pulse shaper 20 to comparator 21 so that the phase difference between these signals can be used to produce an output signal #2. The signal #2 is compared with a fixed potential from potentiometer 34 and depending on its level produces an output on line S indicating a synchronous operation or an output on line S2 indicating synchronous operation. The existence of asynchronous operation may be signalled by a visual 35 or audible 36 alarm or the signal applied to data processor 37. The counter 9 sequences the stepping switch 29 and affords an indication of which motors are running asynchronously. The actual speed of each motor may be determined in cases where the power supply fails, e.g. by a malfunction of frequency charger 14, by closing the switch 40 and measuring the frequency of the regenerated current signal detected by the negative current transformer in counter 41.

Title: Improvements in intercommunication telephone systems
IPC: H04M9/00
Filed: 1929-03-27
Abstract: 308,811. Telefonaktiebolaget L. M. Ericsson. March 31, 1928, [Convention date]. Intercommunication systems.-The subseribocs in an intercommunication system are graded in several ranks of priority so that the higher grade party may use a loud-speaker and a sensitive microphone whilst the lower grade party must use a hand set. For this purpose the lowest graded of the parties is provided with a hand set only. The intermediate parties have both handsets and loud-speaker equipment, whilst the chief party has loud speaker equipment only. Separate speaking batteries are provided for each of the installations fitted with loud speakers. A common signalling battery is fitted, the signal. ling arrangements being by indicator, indicator plus a bell or indicator plus a buzzer on the higher graded installations, and indicator plus a bell on the lowest grade. As shown, four parties A, B, C and D are graded in that order (normally many parties D are connected). The parties A, B and C have loud speaker equipment consisting of two microphones M, a loud speaker HT and a small receiver HL the transfer between these two being by the removal of the receiver from the switch arm HO. Parties B, C and D have hand sets MT. Communication is established by moving the appropriate switch AO, BO &c. in a clockwise direction to ring the party required and in a counter clockwise direction to establish a speaking connection. If, for example, party C wished to speak with party D, switch C04 would be moved in a clockwise direction completing a circuit over contact 1 from battery SB to indicator DS3 and bell RS4. The indicator falls and the bell rings. The switches C04 and D03 are then moved in a counterclockwise direction disconnecting the signalling battery and connecting battery TB3 in series with two branch circuits one including microphone M3 and the receiver of MT4 and the other including the transmitter of MT4 and either loud speaker HT3 or receiver HL3. Similarly if C called B switch C02 would be used for calling and switches C02, B03 for the speaking connection. The battery TB2 would in this case be used to supply talking current whilst hand set MT3 would be used in conjunction with loud speaker HT2 (or receiver HL2) and microphone M2. The switches S01, SO2, S03 are used to control the signal required; in the centre position the indicator AS plus the buzzer SS is used, in the downward position the indicator and the bell RS are connected whilst the upward position provides for no audible signal. The warning lamp SL lights as soon as a switch in the installation to which it belongs is moved to the speaking position. Intercommunication beween the parties D can be arranged, by the provision of additional switches.
