Title: Exchange printout system
IPC: H04M3/36
Filed: 1975-07-15
Abstract: 1520753 Printers COMPAGNIE INDUSTRIELLE DES TELECOMMUNICATIONS CIT-ALCATEL 15 July 1975 [16 July 1974] 29690/75 Heading G4H In a print-out system, a counter decoder connected via a strapping field scans print request signals, acknowledges the print requests and steps through print programmes. 
In Fig. 1, elements OR1-ORk can call for respective print programmes via amplifiers AP and terminals pal-pak which are scanned by a counter CP via a diode-resistor decoder V1, an acknowledgement being sent to the element via storage MP. 
MP also, via two amplifiers in series PI, produces printing of date, time, ticket number &c. 
The element, on receiving acknowledgment, selects sub-routine via amplifiers SP and terminals ps 1-psm connected tothe counter CP decoder V1 which can also call via amplifiers LCA for data from the element, this data being supplied in decimal form (after conversion from binary at DR1 or 2-out-of-6 at DR2) to letter or figure receiver amplifiers RL, RC respectively as appropriate. 
With the counter CP stationary, this data is scanned under control of an auxiliary counter CA, passing via its decoder V2 or V3 and its decoder V4 to letter or figure amplifiers LE, CH respectively. 
The data is then coded in 5-bit telegraph code at DR3 and sent via amplifiers AM and line M to printer IM, counter advance being stopped by a signal AR, and a read command CL going to the printer IM. 
A circuit GS, responsive to CH, LE, detects letter-figure and figure-letter shifts and sends appropriate signals to the printer IM. 
An amplifier RE (top left) permits re-read of data from a programme step already past. 
The counters CP, CA are driven (one at a time) from a circuit CDE which receives a signal SYN from the printer IM after reception by it of each character. 
Counters CK, CMP are used to control carriage return for formatting (counters CP, CA being inhibited). 
The system can be used in a telecommunications exchange in connection with traffic surveillance and maintenance, e.g. automatic testing.

Abstract: 1535113 Poultry storage C V P SYSTEMS Inc 31 Aug 1976 [14 Oct 1975] 36007/76 Heading A2D A method of packaging fresh poultry comprises placing pieces of fresh poultry containing natural juices in a flexible, gas impermeable container, vacuumizing the container, introducing gaseous carbon dioxide thereinto, and sealing the container whereby at least some of the carbon dioxide and at least some of the natural juices form carbonic acid. Suitably, as the carbonic acid forms, the container will contract around the poultry pieces. The container may then be maintained at a cold temperature e.g. 28-40F for an extended time period e.g. up to 40 days.

Abstract: Et element som samvirker med en strøm av fluidum som beveger seg gjennom et rør, fremskaffer periodiske understrømmer med en takt som varierer i henhold til endringene i hastighet av det bevegelige fluidum. Fremskaffelsen av understrømmer modu-lerer også de elektriske ladninger som inneholdes i og beveger seg sammen med nevnte fluidum, for således å tillate en detektor som reagerer på den energi som utsendes av de modulerte ladninger, å fremskaffe et følersignal med en frekvens svarende til genereringstakten for de periodisk fremskaffede understrømmer.Ved en foretrukken utførelsesform er elementet et hvirvelspredende legeme og understrømmene utgjøres av hvirvler som avgis derfra. En elektrisk krets som mottar følersignalet, omformer dette til et strømningssignal som representerer hastig-. heten av det bevegelige fluidum.

Abstract: A non-contacting gas sealing device for a shaft (1) - having a seal housing (2), a stator seal ring (3) arranged in the seal housing (2), and a rotor seal ring (4) arranged on the shaft (1) and fixed to it. The two seal rings (3)(4) interact by means of their seal end faces (3a)(4a) with the interposition of the gas barrier. In the operating condition and under a predetermined differential operating pressure, the stator seal ring (3) has an annular functioning gap (F) relative to a shaft-side cylindrical part of the seal housing (2), the said gap being sealed by a rubber or plastics O ring seal (11) arranged in a groove and being pressed against the gas barrier with a contact pressure determined by at least one pressure spring (7). The stator seal ring (3) also consists of a hard seal material with a high thermal conductivity, a high modulus of elasticity and great hardness. The stator seal ring (3) has such a large geometrical moment of inertia that, in the operating condition and under a differential operating pressure, the thickness of the annular functioning gap between the shaft-side cylindrical part of the seal housing and the stator seal ring virtually coincides with the corresponding structurally predetermined annular assembly gap between the cylindrical part and the stator seal ring (3) in all operating conditions and is smaller than 0.4 mm, preferably less than 0.3 mm. The O ring seal is additionally designed as a compensating centring ring for the stator seal ring (3) and, for this purpose, has a hardness which is greater than the extrusion limit for the hardness of the material at the gap width specified and the predetermined differential operating pressure and is smaller than the hardness figure of 90 Shore A according to DIN 53 505. <IMAGE>
