Title: Method of making cationic latices and the products thereof
IPC: C08C1/02
Filed: 1966-10-06
Abstract: An anionic latex is converted into a cationic latex by the addition of between 1 and 10% by weight of the emulsion of an alkyl ammonium salt or an alkylene diamine salt, the amount of added emulsifier being sufficient to prevent coagulation of the latex when its pH is adjusted to below 7, and the addition of sufficient acid to lower the pH to a valve between 3 and 7.  The preferred latex is that of a butadiene-styrene copolymer.  In an example a cationic butadiene-styrene latex prepared as above is added to a cationic asphalt emulsion.ALSO:A cationic asphalt emulsion has added thereto an anionic butadiene-styrene latex made by adding aqueous lauryl pyridinium chloride solution to a cationic latex and thereafter adding acid to move the pH to a value between 3 and 7 to change the sign of the latex without coagulating the latex.  There is general reference to the use of alkyl quaternary amine salts, alkyl ammonium salts, and salts of alklene diamines as emulsifying agents.

Abstract: 936,555. Prestressed concrete beams. E. WENNSTROM. Dec. 20, 1961, No. 45692/61. Class 20 (4). [Also in Group V] An apparatus for making prestressed concrete beams consists of a mould 1 and stressing means 3 which can be removed from the mould with the concrete beam before the concrete has set so that the final setting takes place outside the mould. The stressing means 3 (Figs. 1 and 2) consist of the two end wall members 5 and 6 of the mould 1 and a telescoping stressing element 7 which is removably secured to the end wall members 5 and 6 and which lies beneath the bottom 8 of the mould in a recess which during casting is covered with, for example, a plate. The stressing element 7 is placed in the mould either before or after the reinforcing rods 4 have been secured to the end wall members 5 and 6 by nuts &c. and the latter moved apart to stress the rods 4. The element 7 then maintains the stress. After the mould has been filled, with concrete, and possibly vibrated, a cover 11 is put on the mould which is then swung about the shaft 12 till it is upside down and the cover 11 is supported by a base. The mould is now removed from the cover leaving the beam, with the stressed rods and stressing means, on the cover 11. After a certain time but before the concrete has finally set the stressing element 7 is removed but the rods are kept stressed since the concrete keeps the end members 5 and 6 apart. Any combination of the reinforcing rods can be stressed.

Abstract: 1509589 Burglar alarms BICOSA SOC DE RECHERCHES 5 Nov 1975 [14 Nov 1974] 45945/75 Heading G4N [Also in Division H2] A solid state switching system, e.g. for operating an alarm 2 comprises a pair of (gate controlled semi-conductor) switches 7, 3 and a triggering device 10 having two discrete resistance values, one of which is relatively high and the other low; the system further including means for putting it into readiness for use. An alarm or a detonator 2 is connected in series with a thyristor 3 across the terminals of a D.C. supply 1, the gating signal for the thyristor being developed by a further thyristor 7 and a trigger device 10, such as a thin wire which has a low resistance when the terminals 9, 9a are connected together and a high resistance when these terminals are disconnected from one another. To put the system into readiness for use a switch 15 is closed, the terminals 9, 9a of the device 10 connected together and the switch 15 opened. A capacitor 13 then begins to charge until it acquires a potential at which the thyristor 7 fires, the system then being ready for use. To fire the thyristor 3 the terminals 9, 9a are disconnected from one another so allowing a potential to appear on the gate 4 of the thyristor 3. After the opening of the switch 15 and the conduction of the thyristor 7, the conditions of transistors 16, 16a, 19 are such that an indicator lamp 18 is illuminated. When the thyristor 7 is rendered conductive, the conditions of the transistors change and the lamp 18 is extinguished thus indicating that the circuit is ready for use. If, when the switch 15 is opened to prepare the system for use, the connection between the terminals 9, 9a is faulty a transistor 22 becomes conductive to inhibit the charging of the capacitor 13 and the transistors 16, 16a, 19 assume a state such that the lamp 18 is unlit to warn an operator that the system is faulty. A further lamp 24 indicates the condition of the alarm 2. Device 10 can be radio controlled.

Abstract: 1536724 Automatic telephone exchanges TEL-TONE CORP 29 Jan 1976 [17 March 1975] 47274/76 Divided out of 1536723 Heading H4K A link for connection between the C, tip and ring leads of a line finder/first selector combination 15, 19 and a port 17 (see Specification 1,536,723) comprises a coupler 36, for sensing the grounding of the C-leads, a line finder detector 31 connected to the coupler 36, a control circuit 33 which controls a link circuit 47 and a line split circuit 45 for connecting the tip and ring leads of a line finder 15 and a first selector 19 to the respective inputs and outputs of a port 17. Operation.-Assuming that the linefinder associated with the link is "pointed" when an associated telephone goes OFF HOOK input C-OUT will be grounded; shortly afterwards the tip/ring loop current causes the associated first selector to return a ground on C-IN. The C-OUT ground is detected by the line finder detector 31 which produces NEW CALL to inform a control circuit 33 that the telephone has gone OFF HOOK. When the link is addressed by the clock and address generator 24, 25, Fig. 2, on leads CLOCK and ADDRESS the control circuit produces signal ACTIVE which causes a link relay circuit 47 to connect T-IN, T-OUT, R-IN, R-OUT to PT-IN, PT-OUT, PR-IN, PR-OUT respectively; (T is for tip, R for ring and P for port). The ACTIVE signals from all links in a group served by the same port are ORed (Fig. 3, not shown) to produce a signal PAVAIL. The ACTIVE causes a line split relay 45 to split the line between T-IN and R-IN and T-OUT and R-OUT respectively. Thus the telephone signals are conveyed to a signal processor via the port. When the signal processing is complete the port activates RELEASE which resets the control circuit 33 causing ACTIVE to return to zero which in turn deactivates the line split relay circuit and link relay circuit; PAVAIL also returns to zero. When a port is "seized" PAVAIL causes a make-busy ground circuit 39 to apply a ground ON C-OUT which informs the associated line finders that the port is busy. This ground is sensed by a current sensor 41 which through an inhibitor 43 prevents the other links from producing NEW CALL. When the conversation terminates a selector detector 36 causes a wink circuit 37 to generate WINK which inhibits the make-busy ground circuit 39 of the conversation terminated link. If two links connected to a common port have their C-OUT terminals grounded at the same time, the link whose address occurs first in the scanning cycle will seize the port; the control circuit 33 of the other link generates a DUMP signal which simulates seizure which causes the associated scanning switch to route the second call to another line finder with an available port. C-IN and C-OUT are connected, through a coupler 36, to a busy indicator 38 which gives an indication when the link is busy, e.g. by lighting on LED (Fig. 5, not shown).
