Title: Silylureas
IPC: C07F7/10
Filed: 1963-11-15
Abstract: Silylureas, including novel compounds, suitable for preparing foam polyurethanes, are prepared by reacting an amido- or aminosilane, R4- nSi(Xn) with an isocyanate R(a)(NCO)y, wherein each R group represents an organic radical linked via a carbon atom to the silicon atom, or two R groups may alternatively constitute a divalent polymethylene radical, X is an amino-, mono- or di-substituted amino or carboxylic amide group, and n is 1,2,3 or 4, R(a) is an organic radical, and y is an integer.  The novel compounds have the formula R4- nSi(NR(a)CO)m -NR1R11n wherein R and R(a) are as above, R1 and R11 when taken singly are organic radicals attached by carbon atoms to the nitrogen atom and when taken together are a divalent organic group, and m is 1 to 12 and greater than n.  Suitable R and R111 groups normally contain not more than 14 carbon atoms and may be unsaturated and/or contain substituents such as OH, SH, CN, NO2, NHR, NR2, CO, SO or SO2.  The carbon atom chain may be interrupted by a hetero-atom or group, e.g. O, S, N, Si, SO, NH, NR. The amino-silane starting materials exemplified are silylated ammonia, silylated primary and secondary amines, silylamino acid esters and silylamido compounds wherein the amido group is derived from urea, buiret, carbamic ester, allophanic esters, carboxylic amides and imides and polyamines and compounds containing more than one silicon atom.  The products of the invention may themselves act as starting materials, more R111NCO groups being introduced by reaction with isocyanate. Suitable isocyanates are mono-isocyanates of the formula R111NCO, where R11 is as defined above, and aliphatic, and aromatic di-, tri- and higher isocyanates; many examples are given.  When excess polyisocyanate is used, a prepolymer having free isocyanate groups suitable for preparing polyurethane foams is formed.ALSO:Silylurea compounds of the formula R4-n Si[(NR111CO)m-NR1R11]n wherein R, R1, R11, R111 are organic groups, (see Division C3) are used for treating textiles and paper.  In Example (9) a cotton textile is dipped into a 5% hexane solution of a silylurea of formula [(C2H5)2 - (OCNC6H5)3]2 Si (CH3)2 to give a product of agreeable touch and increased resistance against humidity, staining and creasing.  In (10) paper is sprayed with a similar solution to reduce its absorption of humidity and increase its wet resistance.

Abstract: 988,744. Solar calculators. COUNCIL FOR SCIENTIFIC & INDUSTRIAL RESEARCH. Nov. 22, 1963 [Nov. 29, 1962], No. 45264/62. Heading GAB. A solar calculator for reading the solar altitude at various times of day and year at a given latitude comprises a slider 22 (Fig. 2) on a cursor 14 rotatably mounted on a chart 24 with scales indicating the date 27, the time of day 26 and solar altitude 25. Hair lines on the slider 22 are located over the date scale and the cursor is then rotated. to cut the required time scale at which point the solar altitude may be read off. This solar altitude may be transferred to a second altitude scale 35 from which the value of the aligned tangent is read off at 36 which gives the depth of penetration of sunlight through a window when multiplied by the height of the window. The disc 13 is transparent and is mounted on an opaque disc 12 (Fig. 3) from which the solar bearing may be determined by setting an aspect mark 30 on disc 13 against the direction in which the observer is facing on scale 31 and then setting the cursor as previously described and reading where hair line 23 crosses the scale 32. Keeping the cursor in this position the solar altitude read on scale 26 is transferred to scale 35 and the radiant intensity on a vertical window is read on chart 33. Different discs 13 for varying latitudes, and different discs 12 with varying charts 33 for surfaces pitched at different angles may be provided. An obstruction diagram of buildings obscuring a window may be plotted on chart 24 to determine when solar radiation into a room will be interrupted.

Abstract: 986,552. Two-part couplings. GENERAL ELECTRIC CO. Ltd. Nov. 20, 1963 [Nov. 30, 1962], No. 45381/62. Heading H2E. Each of the row of pin contacts 10, Fig. 3, of a plug connector for use with an edgetype printed circuit board socket connector, is of non-uniform cross-section along its length to prevent its withdrawal, in one direction, from the stepped bore 7, Fig. 4 (not shown), in the insulating body 1, in which it is accommodated, and has its end 13 deformed at rightangles to the remainder of its length to secure it within the body. The end 13 also provides a terminal to which leads from components mounted on the board 3 may be soldered. The body 1, moulded e.g. from nylon, has a lip 4, along its length, by which it is located on the board 3, being secured by screws or bolts 2 at either end. The pins 10, which are preferably of a gold-plated copper-base material, occupy certain of the holes 7, the ends 13 being bent up into the slots 19, Fig. 3, which are alternately of different lengths in order that the ends 13 will be in a staggered formation, to facilitate soldering. The thickness of section 14 of the body 1 is less than the diameter of the ends 11, of the pins, which thus provide contact surfaces for cooperation with the edge-type socket contacts. Specification 986,551 is referred to.

A load dependent indirectly acting compressed air system for a rail vehicle has an " empty " brake cylinder 5 and a " load " brake cylinder 6 which act on a brake linkage 15 having a restoring spring 18, a control valve 2, a pressure transmitter 4 which acts to supply compressed air to the " load " cylinder 6 in dependence on the vehicle loading and pressure limiting valve 7 which is held in an open position by a spring 22 as long as the pressure of compressed air coming from the control valve 2 does not exceed a certain value and the action of the pressure limiting valve 7 is such as to supply the " load " cylinder 6 with compressed air even in the case of an empty or partly loaded vehicle. As shown in Fig. 1, one side of a piston 8 is acted upon by the pressure from the valve 7 and the other side of the piston 8 is acted upon by the pressure in the " load " cylinder 6 via a choke bore 9. The pressure transmitter 4 includes a piston 19 acted upon by pressure from the control valve 2 and serves to actuate an inlet valve 11 via a lever 20, which lever 20 is mounted on a roller 21 which is movable in accordance with the vehicle loading to alter the lengths of the two parts of the arm 21. When the pressure in a main line 1 is lowered the control valve 2 causes compressed air to be introduced to the " empty " cylinder 5, and the inlet valve 11 is actuated to introduce air into the " load " cylinder 6 in dependence on vehicle loading. However, even in the case of an empty or partly loaded vehicle compressed air will be introduced for a short time into the " load " cylinder by movement of the piston 8 to open the inlet valve 11, after a period of time however the valve 7 will be closed by rising pressure and the piston 8 will be moved back by compressed air flowing from the " load " cylinder 6 via the choke bore 9. In the embodiment of Fig. 2 the piston 8 and the choke bore 9 are replaced by a double non-return valve 10.

Abstract: 1,133,475. Optical apparatus. EDWARDS HIGH VACUUM INTERNATIONAL Ltd. Oct.24, 1966 [Nov.11, 1965], No.47890/65. Heading G2J. [Also in Division G1] Apparatus for measuring optical characteristics e.g. optical density or thickness of coatings on ophthalmic lenses includes a light source 12 focused by lens 13 in the plane of the lens 7 under test, substantially all the light transmitted by the lens being directed to a photo-cell 11 by a light guide 8. This arrangement ensures that the optical properties, e.g. focal length &c. of the lens do not enter into the measurement. Thus, when as in the embodiment described, a number of lenses e.g. 6, 7 of different optical properties, mounted in a rotating holder 3, are being coated simultaneously by deposition of a metallic oxide in a vacuum enclosure 1, the output of the photo-cell 11 remains substantially constant and is representative of the coating thickness and not dependent on the optical characteristics of individual lenses. The light guide may be a glass or plastics tube or rod aluminized on its outer surface.
