Title: A process for the manufacture of organo-silicon compounds
IPC: C07F7/18
Filed: 1947-07-01
Abstract: Organo siloxanes are prepared by hydrolysing compounds of the general formula R3Si(CH2SiR2)mY, wherein the R's are the same or different and each is a monocyclic aryl or alkyl radical, m is a positive integer, and Y is halogen or an alkoxy radical, and condensing the hydrolysis product.  Some of the R groups may be methyl radicals and the remainder monocyclic aryl radicals.  The halogen may be bromine or chlorine, and the alkoxy radical may be ethoxy.  In example 5, apart from the compounds of definite formula, an oily residue is obtained.  Specification 631,619, [Group IV (b)], is referred to.ALSO:Organo-siloxanes are prepared by hydrolysing compounds of the general formula R3Si(CH2SiR2)mY, wherein the R's are the same or different and each is a monocyclic aryl or alkyl radical, m is a positive integer and Y is halogen or an alkoxy radical, and condensing the hydrolysis product.

In examples compounds of the formul [(CH3)3SiCH2Si(CH3)2]2O, {(CH3)3Si[CH2Si(CH3)2]x}2O, where x is 2, 3, 4 and 5; [C6H5(CH3)2SiCH2Si (CH3)2]2O, [C6H5(CH3)2SiCH2Si CH3C6H5]2O and [(CH3)2C6H5SiCH2Si CH3n-C4H9]2O.  An organo silicon compound of the formula (CH3)3Si[CH2Si (CH3)2]3OC2H5 is prepared by reacting (CH3)3SiCH2Si (CH3)2CH2Si(CH3)2Cl (obtained from the corresponding ethoxy compound by reaction with acetyl chloride) with an organo silicon compound of the formula ClCH2Si(CH3)2OC2H5 in the presence of sodium.  The product may be converted to the corresponding compound in which chlorine replaces the ethoxy group by reaction with acetyl chloride.  An organo silicon compound of the formula (CH3)2C6H5\SiCH2SiCH3 SiCH3C6H5OC2H5 is prepared by reacting (CH3)2C6H5SiCl and ClCH2SiC6H5CH3OC2H5 in the presence of sodium.  2 - n - Butoxy - 2 : 4 : 4 - trimethyl - 2 : 4-disilopentane is obtained by heating an organosilicon compound of the formula (CH3(3SiCH2Si(CH3)2OC2H5 with n-butyl acetate.

Title: Coating composition atomizing head
Inventor: SCHWEITZER HOWARD VINCENT
IPC: B05B5/03
Filed: 1956-05-31
Abstract: 789,581. Spray-producers. SCHWEITZER ELECTROSTATIC CO. May 31, 1956, No. 16876/56. Class 69 (3). An atomizing head has an elongated chamber 13, 14, open at 15, in which a tapering needle 40 is mounted, and the needle is supported by a transducer 31 which vibrates it ultrasonically to atomize liquid flowing over the surface of the needle and supplied from an inlet 81. The chamber is constituted by bores 13 and 14 in a plug 11 and body 10 respectively, and the needle shank 41 is attached to the front face of the transducer which is press-fitted in a sleeve 30 slidable in a bore 25. A hollow stem 50 is attached to the sleeve and to a piston assembly 52 slidable in a chamber 22 and, in the non- spraying position, a spring 65 urges the needle against a seat 45 of the bore 13. A cap 16 fits over the plug and is screwed to the body, and defines an air manifold 17 to which low-pressure air is fed from an inlet 80. In order to effect spraying a high-pressure air supply is fed to an inlet 82 and passage 86 whereby the piston and needle &c. are moved rearwardly to allow the flow of liquid, fed to an inlet 81, along the tapered sides of the needle; simultaneously a high-frequency electric current is supplied to the rear end of the transducer by a cable 61 to produce the ultrasonic vibrations. Low-pressure air from the manifold 17 passes through passages 84 and carries away the atomized liquid. Outlet ports 90 communicate with the manifold and air passing therethrough assists the spray dispersal. In order to charge the spray electrostatically a high potential is supplied to the needle by a lead 91 to cause corona discharge at the needle tip 42.

Emitter 1 and heat-transfer element 23 are of Mo, Ir, Ta, Re or W, and are held spaced apart by a small distance so that melted ceramic material flows therebetween by capillary action, Fig. 2 (not shown). In an alternative arrangement, emitter 1 may be bonded directly to pipe 21. Flat emitters may be similarly bonded to a common heat source. As shown, collector 3 is provided with cooling fins 19, but a plurality of collectors may be insulatingly bonded to a common heat sink in accordance with the invention, lower melting-point ceramic materials such as quartz and fused silica being used with collector and cooling elements of Ti, Zr or Cr. Specific dimensions are given.

Abstract: 1310384 HANSON SCALE CO 13 April 1970 [18 April 1969] 17537/70 Heading G1W A bathroom scale comprises a base 12 and a cover enclosing pairs of levers 24, 26 adapted to transmit the load imposed on the cover to a tension spring 32 supported on a post 30 by the ends of the levers 24 pressing on a washer 28 carried by the spring. A lug 36 on the washer 28 bears against a crank 40 which is pivotally mounted in a support 50 which is itself pivotally supported in a channel sectioned member 54 extending from front to back and secured to the base 12. The pivot connections between the crank 40, support 50 and member 54 comprises holes in these members and a U shaped pin 62 each leg of which serves as a pivot connection between the components. A torsion spring 64 wound about one leg of pin 62 has its ends lodged under a lug 65 on member 54 and the second leg of the pin 62 so that the legs of the pin are resiliently urged into contact with the surrounding surfaces of the holes thereby avoiding any looseness in the pivoted connections. A rod zero adjustment 52 is engaged in a hole 46b in the support 50 and has a screwed adjusting knob 52c at its other end. The spring 64 also serves to hold the rod 52 resiliently in engagement with the hole 46b. The crank 40 is provided with an arm 66 which is pivotally connected to a rack 68 in toothed engagement with a pinion 80 coupled to disc 84 carrying indicia 86. Adjustment of the knob 52c causes the support 50 to pivot in the channel sectioned member 54. The crank 40 being in engagement with the lug 36 of washer 28 is consequently caused to rotate slightly following which the rack 68 rotates the disc 84 and the scale is correspondingly adjusted in relation to its position adjacent a magnifying lens 88.
