Title: Can testing machine
IPC: G01M3/32
Filed: 1936-04-27
Abstract: 463,677. Testing cans for leaks. BLISS CO., E. W. April 27, 1936, No. 11965. Convention date, April 25, 1935. [Class 106 (ii)] A can-testing machine comprises a can sealing packing, a can plunger for holding a can against said packing, and spring means for moving said plunger into can holding relation. Cans 65 fed down a slide 185 are picked up by a star wheel 52 and delivered to clamping units spaced around the circumference of a wheel 42 the hub 33 of which rotates on a cylindrical chambered member to which fluid under pressure is delivered and which distributes it to the units. A slide 73 operated by a cam groove will be moved by its spring 73a to move through a toggle mechanism 70a rod 62 with plunger head 63 to clamp a can 65 between the head 63 and a packing 58. After this has been done, the piston 93 moves a bucket member 97 over a can and against the packing 58 the restricted space between can and bucket being then vented to atmosphere. Air under pressure is next charged into the can through the opening 59 and the pressure is maintained for the major part of a revolution until the detector station is reached. At this point the restricted space is placed into communication with one of two sylphons, these being arranged to co-operate with alternate units. If compressed air from the can has leaked into the restricted space the sylphon expands and makes an electric contact to cause energization of a solenoid to push out a pin in a wheel 160 so that in the rotation of the wheel the pin engages an arm 182 to move and set a segregator 177, after which operation the sylphon is vented. The defective can is then forced into spring U-grips 190, 191 and carried round to be delivered at point 196. Normal cans leave at 194. More than two sylphons could be used if desired.

Title: Digital apparatus for obtaining data on telephone traffic
IPC: H04M3/36
Filed: 1970-03-17
Abstract: 1298246 Automatic exchange systems SOC ITALIANA TELECOMMUNICAZIONI SIEMENS SpA 17 March 1970 [19 April 1969] 12738/70 Heading H4K A group of subscribers lines are monitored on a cyclic basis so that full details of all calls instituted thereby may be recorded. The monitoring system includes a scanner which is stepped by an address register once per cycle of 800 Ásecs. so as to examine in turn each of the c wires of the 100 lines in the group to thereby determine their on-hook/off-hook status. Upon finding a line off-hook, the line's identity is inserted in a free compartment of a magnetostrictive delay line memory together with an indication of the time at which the off-hook condition was detected. (The memory comprises four, 800 Ásec. recirculating lines in which data is recorded in decimal coded binary 4 bit form. The address register occupies a number of 1 Ásec. bit positions on these lines). A digit analyzer is connected to the calling lines a, b wires so as to determine, the value of each digit, the length of each interdigital pause, the end of dialling, the clock time at the end of dialling and the occurrence and time of the called party reply or hang-up (premature, or after busy tone) of the calling party. All this information is gathered during successive 800 Ásec. cycles in response to the appearance of the calling party's identity at the output of the memory. (The latter incorporates the feature that two succesive bits may be read-out simultaneously, so that with two digits completely defining each of the 100 subscribers in the group, each calling subscribers line can be interrogated once per cycle with the minimum of equipment in the central monitoring system). The data is stored in successive compartments of the memory following the calling partys identity. Although the amount of storage required varies from call to call, particularly if trunk dialling is involved, the Specification dces not mention how the identities are inserted in the serial memory such as to make optimum use of the memory. Albeit, when the called party replies (as detected by potential changes on the a, b wires) or when the caller hangs up without an answer (as detected by potential change on the c wire), the monitoring system causes the data concerning the call to be destructively read-out via a buffer store to a printer or the like. The c-wire is then again monitored at the 80 Ásec. rate (i.e. 100 x 800 Ásec.) until the end of call criterion is recognized whereupon a compartment of the memory is seized so as to store the calling line identity and the clock time at which hang-up coccured. This date is destructively read-out to the printer. Certain aspects of the memory organization and of the neccesary logic for implementing the monitoring are touched on more fully in the Specification.

Abstract: 495,313. Automatic tuning correction. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., RUST, N. M., and KEALL, O. E. May 4, 1937, No. 12782. [Class 40 (v)] In order to prevent the tendency of an A.F.C. system from holding in to a strong signal in preference to an adjacent desired signal of comparatively weak strength, the error detector or discriminator networks are designed to peak respectively at about 1 kc. each side of the true I.F., and fall away rapidly in response thereafter as shown in Fig. 2. The frequency control device, either a thermionic reactance or a meter-operated condenser has a characteristic as shown in Fig. 3, the relationship between tune-correcting voltage and frequency change being linear over portion SP and thereafter no substantial change takes place over portions S1, S2. This may be effected by suitable choice of a short-base variable-mu valve as the control tube, or by shaping the condenser vanes of a meter-operated condenser or in the last case, resilient limit stops for the condenser are provided. The frequency range of the portion SP should be less than twice the channel separation of stations normally received, e.g. 18 kc. Reference has been directed by the Comptroller to Specification, 474,967.
