Abstract: 389,563. Changing signs. WEST, C., 65, Dunloe Avenue, Tottenham, and CRISP, C., 17, Throgmorton Avenue, both in London. Nov. 19, 1931, No. 32065. [Class 3 (i).] In signs comprising a pack of independent display panels which are transferred one by one from a front viewing position to the rear of the pack by endless moving chains, means are provided whereby the period of display is lengthened without slowing down the speed of transfer. The panels 3 have channelled end bars 19 which are engaged by a pin 8 on the chain 6. The pin 8 is carried on the end of a lever 27a pivoted at 28 to the chain and having an inwardly extending tongue 30 rigid therewith. An axial spring keeps the pin 8 normally in line with the chain 6, and a stop 39 bearing on the chain may be provided on the lever 27a to limit the inward motion of the pin. A cam 32 having a notch 33 is rigidly fixed on the shaft carrying the chain sprocket 24, and the length of the chain. 6 is such that the finger 30 does not enter the notch 33 each time it comes round but only, say, every third revolution. When the finger 30 enters the notch the pin 8 functions to transfer a panel 3, but when the finger 30 abuts against the cam 32 the pin 8 is forced out of the line of engagement with the bars 19. The panels 3 may be rigid or flexible, and may remain in a vertical position during transfer or be reversed to exhibit both sides in succession. When flexible panels are reversed, a prong 4c on the inclined panel-supporting rail 4 guides the following bar 19 of each panel on to the rail 4, while the leading bar is carried on by the chain 6 to the lower position. A spring-- pressed buffer 25, or a friction device 26, or both may cushion the following bar 19 in its fall on the rail 19. The device 26 consists of a spring blade mounted on a shaft 27 and pressed to bear frictionally on the end of the bar 19 by a spring 27b. Fig. 3 shows a modified construction in which the pin 8 is normally pressed by its spring out of the way of the bars 19, and is forced back thereinto by a pivoted cam 34 controlled by an electromagnet 35. The magnet 35 is energized through contacts 37, 38, the contacts 37 being removable and interchangeable on a drum 36 geared to the chain 6.

Abstract: 853,119. Automatic exchange systems. TELEFONAKTIEBOLAGET L. M. ERICSSON. Oct. 10, 1958 [Oct. 11, 1957], No. 32479/58. Class 40 (4). Metering apparatus records the several stages of a call on a common tape, the stages being identified by a prefix number and by the number of the link relay set used in setting up the call. A calling subscriber A is connected by a marker M to a free link circuit relay set SR which is then connected by the marker to a free register REG. The wanted number is stored in the register REG which sets up the different selector stages. When the connection is made the register is dismissed. The tape H may be magnetic or photographic or it may be punched. It is advanced step-by-step, each step comprising 17 recording positions, Fig. 9. Control circuit SDM obtains from the marker M the calling number and the number of the link circuit relay set SR and feeds this information to SD to be entered as the first record in respect of a call together with a prefix a. This record requires two steps of the tape. Control circuit SDM then connects SR to recording circuit SD through a selector SDS to register the called number together with the SR number and prefix b. SDM also connects the register to the recording circuit SD to register information D.T.O.K. concerning the category of the called subscriber. When the called subscriber answers SR again calls and is connected to SD by SDS under the control of SDM so that prefix c, the SR number and time are recorded. At release the same information is recorded with prefix d and a disconnect mark. If metering is effected on the basis of a constant fee and variable time interval then recording with a prefix f is made at suitable intervals throughout the duration of the call. If the call is unsuccessful an annulment mark is recorded. At the beginning of each day a prefix e precedes recording of the date. The symbol MX in line a of Fig. 9 may be used to indicate a call from a coin-box or a P.B.X.
