Abstract: 1316457 Foamed coatings POLYMER CORP Ltd 23 Sept 1970 [24 Sept 1969] 45373/70 Heading B2E [Also in Division C3] A suported embossed latex foam layer is obtained by foaming a film forming aqueous latex compound, free of gelling agent, comprising (a) a latex of a curable rubbery polymer, (b) a curative system and (c) a foaming agent capable of producing a highly substantive latex foam, which will resist heating at temperatures suitable for drying the foam, without collapsing, removing at least a major proportion of the water from the foam layer by heating without causing diminution in the thickness of the foam layer and with no curing of the polymer and embossing the layer at a temperature sufficient to cure the curable polymer. Preferably at least 90% of the water is removed from the foam. Suitable polymers are natural rubber and homo- and co-polymers of conjugated alkadienes of 4-8 C atoms, e.g. butadiene, isoprene or chloroprene. Numerous suitable materials are listed. Specified foaming agents are amphoteric emulsifiers of formula R-N(R 1 )-R 2 -COOM, where R i  is the group -R 2 -COOM, hydrogen, or a 1-5C alkyl group, R 2  is a straight chained or branched alkylene group of 1-5 C atoms and M is a cation which renders the emulsifier water soluble. Suitable materials are listed. Fillers, e.g. calcium carbonate, silica, clay, anhydrous aluminium silicate, barytes, talc and lithopone, may be present. Suitable curative systems contain a vulcanising agent, e.g. sulphur, an activator, e.g. zinc oxide, a primary accelerator, e.g. thiuram or dithiocarbamate and a secondary accelerator, e.g. thiazole. Support materials listed are carpets, fabrics, cotton mesh, nylon tricot, jute fabric and non-woven materials. Preferably the foam layer is applied to a thickness 1/16-1/2". The embossing may be carried out using heated rollers. In a modification of the process a solution of a watersoluble accelerator, e.g. a carbamate, may be sprayed onto the dried foam prior to embossing.

Abstract: 1394516 Reciprocating pumps and motors ROBERT BOSCH GmbH 10 Oct 1973 [10 Oct 1972] 47377/73 Heading F1A In a radial piston pump or motor comprising a rotary cylinder block 31 supported on a pintle valve 3 having inlet and outlet ports 6, 7, the block 31 is centralized on the pintle in operation by the action of pressure fields produced by two pairs of recesses 11, 12, 13, 14 and 15, 16, 17, 18 associated with each port, recesses 11, 12, 17, 18 being inter-connected as one group, and recesses 13, 14, 15, 16 being inter-connected as another group, and the two groups being connected by respective passages 19, 20 to a slide valve 21 responsive to the pressures at diametrically opposite positions in the clearance between the block and the pintle. As shown, ports 6, 7 are connected via check valves 27, 28 to supply working pressure to valve 21, through passage 26, and to ports 45, 46 at diametrically opposite locations in the pintle surface. Recesses 47, 48 in the cylinder block intermittently connect ports 45, 46 to ports 39, 40 in the pintle connected via throttles 43, 44 to end-faces of valve 21. The pressures transmitted by ports 39, 40 to the valve are different when the block is not central on the pintle, so that valve 21 is moved by the pressure differential to connect the appropriate group of pressure field recesses to pressure to centralize the cylinder block. Springs 29, 30 bias valve 21 to its mid position. The valve is located in the pintle, Fig.5 (not shown). In Fig.6 (not shown), one group of pressure field recesses is of larger area than the other, the smaller recesses being continuously connected to high-pressure, and the valve operating to connect the larger recesses to high-pressure as before. In Fig.7 (not shown), high-pressure passage 26 is additionally connected to the endfaces of the slide valve via throttles, and ports 39, 40 are connected between the respective throttles and end-faces.

Abstract: 1,144,102. Isomerizing hydrocarbons. TEXACO DEVELOPMENT CORP. 23 Oct., 1967 [17 Nov., 1966], No. 48032/67. Heading C5E. Isomerizable hydrocarbons, particularly C 1-7  paraffins, containing as impurities oxygen compounds, sulphur compounds, nitrogen compounds and/or saturated hydrocarbons, are freed from said impurities by contact with a molecular sieve and are then catalytically isomerized in the liquid phase in the presence of hydrogen, the isomerization effluent being separated into a liquid phase from which isomerized hydrocarbon is recovered and a gaseous phase which is used to desorb impurities from a spent molecular sieve. The hydrogen used for the isomerization may also be previously passed through a molecular sieve. A suitable isomerization catalyst is platinum/ alumina. Suitable sieves for removing impurities are of 4Š size, and may be used in pairs. Prior to isomerization the feed may be hydrogenated for removal of aromatic, e.g. over Ni/Al 2 O 3  catalyst, and may also be passed through a 13 x sieve as a catalyst guard.

Abstract: 1378756 Measuring yarn production STRUMPFKOMBINAT ESDA THALHEIM VEB 20 Oct 1971 48738/71 Addition to 1350258 Heading D1F In a method for continuously determining the weight of yarn produced on, and the work performed on, yarn processing machinery having a plurality of yarn handling devices, detectors 1 indicate the presence or absence of yarn being handled by each device. Each detector 1 is scanned by stepping mechanism 2 controlled by timer 3, the signals from each detector controlling gate circuit 5. Transmitter 6 emits an electric signal for each revolution of a machine part which moves proportionally to the length of yarn passing each work station and the signals are counted as yarn weight on counter 7. If no yarn is forming at a station when scanned, the signal from the corresponding sensor 1 closes gate 5 to the signals from transmitter 6, and the signals are then not counted. The work performed is measured as the number of yarn breakages which have been repaired. If a signal from a detector closes gate circuit 5, a signal is passed to change the switching state of a bistable multivibrator 9 associated with the detector. If the detector subsequently emits a signal indicating the presence of yarn, the switching state of the multivibrator is changed, and it then emits a signal to actuate counter 10 to indicate a further yarn repair. The sensors may be thermal resistors.

Title: A method of electrically interconnecting double-sided printed circuits
Inventor: LUCEK JIRI
IPC: H05K3/00
Filed: 1965-11-19
Abstract: Printed circuits on opposite sides of an insulating base sheet are inter-connected by punching or drilling holes in the sheet with a punching tool or drill bit provided with a recess or groove filled with a conductive medium which forms a coating on the wall of the holes formed, the coating being smoothed by withdrawal of the tool or bit, and then immersing the sheet in an electro-plating bath to form an electro-plated connection between the circuits via the walls of the hole. Preferably the tool or bit passes through a container holding the conductive medium before effecting punching or drilling of the sheet as by forming the container as a cavity in a guiding plate.  In the electro-plating step, an insulating member contacts the side of the sheet remote from the anode and a conductive member is contacted with the other side of the sheet, both members engaging the sheet where electro-plating is not desired.  Typically the insulating base sheet is of glass fibre impregnated with epoxy resin, the conductive medium applied by the tool or bit is an aqueous graphite emulsion, and electro-plating is effected with an acid copper bath containing organic inhibitors as in Specification 1,064,769 to give a hard copper deposit.

Title: Method of operating a computer to produce test case programmes
IPC: G06F11/36
Filed: 1976-11-25
Abstract: 1510240 Generating test case programs for testing computers INTERNATIONAL BUSINESS MACHINES CORP 25 Nov 1976 49278/76 Heading G4A A method of operating a computer to produce test case programs, written in a predetermined computer language, which are suitable for testing the input-output (I/O) instruction handling capabilities of a computer program, comprises operating the computer to produce a data declaration for use by a test case program, the data declaration having a predetermined structure comprising a predetermined number of records each record including at least one data item having a predetermined value, generating a group of I/O instructions each in accordance with the rules of the predetermined computer language, predicting the effect of the execution of and ensuring the executability of each generated instruction, generating instructions that in execution of the test case program compare the predicted values of the records with the actual values, and storing each generated test case program in a form suitable for use in a computer. The method is distinguished from the similar method of Specification 1,479,122, which is referred to, in that when an instruction is generated that would normally cause an error condition, that instruction is included in the test case program together with a routine to divert the test case program to the next generated instruction when the error condition is recognized by a computer program under test, in order to test that computer program's ability to detect and handle error conditions. I/O operations may be controlled by a virtual storage access method (VSAM) program, and prediction of the effect of the execution of each generated instruction may include maintaining a dictionary containing records which reflect records kept by the VSAM program. The VSAM program may allow data to be stored in a plurality of different forms, the method then including the steps of selecting which form of storage shall be used for any one group of generated instructions and maintaining the appropriate dictionary records. As described the different forms are (1) key-sequenced data sets (KSDSs) (each includes at least one index containing keys identifying particular records), (2) entry-sequenced data sets (ESDSs) (each stores records in their received order, no amendment of a record being permitted except overwriting by a record of identical length) and (3) relative record data sets (RRDSs) (each stores records in a string of fixed length slots). The generated instructions operate on these three forms of data storage on a random basis. If a KSDS has more than one index, the choice between them is also taken on a random basis. Flow charts illustrating the application of the method to the generation of test case programs written in PL/1 are described with reference to Figs. 1 and 3-7 (not shown).
