Title: Transmission of asynchronous information in a synchronous serial time division multiplex
IPC: H04L5/24
Filed: 1972-07-10
Abstract: 1378035 Data transmission; multiplex pulse signalling SIEMENS AG and TELEFONBAU UND NORMALZEIT GmbH 10 July 1972 [8 July 1971] 32157/72 Headings H4P and H4L In a data switching system one processor asynchronously compiles the addresses of lines exhibiting polarity reversals for despatch to a second processor, such addresses being transmitted over a synchronous time division multiplex highway and each address being associated with a timing code so that the second processor can restore the original irregular time spacing of the addresses as produced by the asynchronous compilation of the first processor. The synchronous time division multiplex highway provides in each of cyclic periods T 0  a synch, channel and N address channels where N is the maximum number of line addresses the processor can produce in a period T 0 . Two shift registers operate in alternation for transmission, one register being read out to the highway while the other is being loaded ready for transmission in the next period, Fig. 3 (not shown). As addresses arrive from the processor they are steered into successive channel stores of a register along with a direction of polarity change bit and a clock code to indicate time of reception in the highway period T 0 . The division of the highway period T 0  into clock codes is relatively coarse and allows two or more successive line addresses to be loaded with the same clock code if they arrive at a rate higher than the clock rate. At the receiving processor, Fig. 4 (not shown), similarly comprised of stepping registers worked in alternation, timing is governed by the received synch. codes to provide a cycle of timing codes throughout each period T 0 . By this means read out is sequential but read out of each address is delayed until the timing code associated with each received address finds a match in the cycle of timing codes produced at the receiver. Where two or more sequential addresses have the same associated timing code, read out of that group is sequential and not subject to delay.

Title: High Slip Polypropylene Film
IPC: C08L23/12
Filed: 1968-07-05
Abstract: 1,180,156. High slip polypropylene film. CROWN ZELLERBACH CORP. 5 July, 1968 [24 July, 1967], No. 32184/68. Heading B5B. [Also in Division C3] A blend of polymeric materials for the extrusion casting of high gloss, relatively high slip film comprises from 80% to 98% by weight of polypropylene homopolymer, from 2% to 20% by weight of a copolymer of ethylene and propylene having an ethylene content of less than 30% by weight of the copolymer and an isotactic content of at least 50% and a sufficient amount of slip additive to impart to a film cast from the blend a coefficient of friction less than 0À3. Both the homopolymer and copolymer may have isotactic components of at least 50% (preferably above 90%) by weight and a melt flow between 3 and 15. The slip additive is a C 15 -C 24  fatty amide, e.g. erucyl amide, oleyl amide, stearyl amide or hydrogenated tallow amides, and typically amounts to between 0À075% and 0À2% by weight of the blend. An anti-block agent such as diatomaceous earth or finelydivided silica may be included in similar proportions. The materials may be blended in particle form (pellets) at ordinary temperatures with the necessary intermixing at elevated temperatures taking place in the extruder itself. An example is directed to the production of polypropylene film having a calliper of between about 0À5 and 8 mils by extruding a dry blend of 0À20 inch pellets of polypropylene, 0À24 inch pellets of ethylene-propylene copolymer (3% ethylene content) and slip additive (80% erucyl amide, 12% oleyl amide and 8% stearyl amide) in stated proportions through a barrel of diameter 3À5 inch and of length-todiameter ratio of 24 : 1 on to a casting or chill roll providing a film take-off speed of 245 feet per minute. A vacuum chamber was positioned between the extruder and the chill roll with its suction slot facing the trailing edge of the film. The melt temperature of the polymeric material was 555‹ F., the die temperature 550‹ F. and the chill roll was maintained at 80‹ F. There was less " plate-out " of the slip additive the chill roll when the ethylene-propylene copolymer was included in the blend.

Title: Process for the manufacture of aldehyde condensation products
IPC: C08G12/12
Filed: 1928-11-06
Abstract: 301,798. Kunstharzfabrik Dr. F. Pollak Ges. Dec. 5, 1927, [Convention date]. Drawings to Specification. Urea-formaldehyde condensation products. - Transparent products from carbamides, particularly urea, and aldehydes, particularly formaldehyde, containing no free aldehyde, may be obtained by condensing less than two molecules of aldehyde in acid solution with one molecule of the amide, in such a manner that an excess of free formaldehyde relative to the urea introduced at any time and not yet combined is present at each stage of the process. According to a general example, the reactants are condensed by pouring or dropping a strongly acid urea solution into a formaldehyde solution, preferably boiling. The amount of urea added per unit time is reduced in accordance with the removal of free formaldehyda by the addition of the previous quantity of urea, thus giving an excess of formaldehyde relative to the amount of free urea introduced at any time, while gradually reducing the total amount of the formaldehyde, so that on completion of the reaction, no free formaldehyde is present, and a product is obtained with one molecule of urea combined with one and a half molecules of formaldehyde. In practice, a lower limit is fixed, at which the remaining amide is added as a whole. The rate of addition of the urea is regulated according to the acidity of the solution, so that the whole of the urea combines before gelatinization occurs, but the acid process may be interrupted or preceded by neutral or alkaline stages.

Title: Method of preparing concrete mixtures
IPC: B28C7/04
Filed: 1959-09-23
Abstract: During the weighing of the components of a concrete mixture by balances, the moisture content of the components is determined by weighing a constant volume of each component with weighing devices associated with the balances and comparing this weight with the dry weight of the same volume and the amount of gauging water needed to obtain a given water-cement ratio is then adjusted according to the water content of the components.  In an example a concrete consisting of two sands and three gravels of varying sizes in a ratio of 21 : 7 : 36 : 22 : 14 is mixed to give a water-cement ratio of 0,40, the water content of the two sands (0,1-0,8 mm and 0,8-3,0 mm) and the fine gravel (3,0-12 mm) being determined during the weighing.

Connections over a multi-stage matrix switching network are set up by a marker which selects idle links according to preferred sequences of choice which sequences are varied from time to time to equalize traffic distribution, the schedule of sequences in force being exploited by a test routiner to identify the co-ordinates of routes for testing. The routiner may demand any particular order of choice for tests and may switch from one order to another when a demand for a connection finds a link busy at the first order of choice. The routiner preferably gets access to the network at that stage having the fewest links. Where 400 subscribers are concentrated to 100 junctions the routiner would connect with the junctions and a test connection would extend from one junction to a subscriber's inlet and back from that inlet to a second junction. The identity of links which are not available for test at the indicated order of choice, due to use in normal connections, is recorded so that the routiner can return to a test of the links at a later time.
