Title: Organo-silicon compounds and a process for the manufacture thereof
IPC: C07F7/18
Filed: 1950-02-08
Abstract: The invention comprises organo-silicon compounds of the general formula <FORM:0684102/IV (b)/1> wherein each R is an alkyl or monocyclic aryl radical and each Z is an alkoxy radical, and a process for the preparation of the above compounds by reacting in the liquid phase an alkali metal and the compounds XCH2SiRZ2 and R2SiY2, wherein R and Z have the above significance, X is a halogen atom and each Y is an alkoxy radical or a halogen atom.  The preferred R radical is the methyl radical, but R can represent any alkyl radical up to the octadecyl radical or the phenyl, tolyl or xylyl radical. Preferably the radical X is chlorine or bromine and the radical Y is the ethoxy radical.  In the examples the compound (C2H5O)2CH3SiCH2Si (CH3)2SiCH3(OC2H5)2 is prepared from the compounds ClCH2(CH3)Si (OC2H5)2 and (CH3)2SiCl2, and the compound <FORM:0684102/IV (b)/2> is prepared from the compounds ClCH2C6H5Si (OC2H5)2 and C6H5(CH3)Si (OC2H5)2.  Chloromethylmethyldichlorosilane is prepared by the direct chlorination of dimethyldichlorosilane or by chlorinating methyltrichlorosilane and then reacting the product with a methyl Grignard reagent.  Similar compounds may be prepared by using other Grignard reagents, e.g. ethyl- or octadecyl Grignard reagents or aryl Grignard reagents such as the phenyl Grignard reagent, in place of the methyl Grignard reagent referred to above.  The chlorine atoms attached to silicon in the products may be replaced by alkoxy groups by reaction with alcohols.

Title: Improvements in machines for cutting shingle strips
IPC: D06N5/00
Filed: 1920-02-09
Abstract: 138,876. Flintkote Co., (Assignees of Overbury, F. C.). Aug. 12, 1915, [Convention date]. Rotary type for cutting designs and for cutting rectilinearly.-In a machine for severing shingle strips from a coated fabric roofing &c. material, tongue portions d, Fig. 7, are first cut by cooperating cutting-rolls, and the web is then completely severed along the line f by a second rotary cutting-appliance. The upper cutting-roll 14, Fig. 6, comprises segmental slitting-blades 22 and cross-cutting blades 24 which are adapted to coact with corresponding shear-blocks on the lower cutting-roll 15 to slit the work as at b and c, respectively, Fig. 7. The tongue portions d, thus slit, are deflected from the plane of the material by the shear-blocks. The material is then passed between feed-rolls 12, 11, recessed to accommodate the upturned tongues, and is severed transversely into strips at the position f, Fig. 7, by a rotary blade 27 adapted to co-act with a fixed blade 26. The severed strips pass down an inclined plate 30 on to a series of endless carriers 31 between which the detached tongue portions fall. The cutters may be modified in shape to cut strips with tabs not necessarily of rectilinear shape.

Title: Improvements in or relating to pulse generators
IPC: H03K5/156
Filed: 1945-02-16
Abstract: 590,215. Pulse generating circuits; television. ANDERSON. E. W., and McDERMOTT, T. J. Feb, 16, 1945, No. 4027. [Classes 40 (iii) and 40 (v)] A circuit for producing .signals, suitable for synchronizing signals in a television or pulse multiplex communication system, and consisting of a plurality of discrete pulses comprises a triggering circuit for deriving rapid voltage changes from a control voltage, a delay circuit to convey the voltage changes to a utilization point and back, and means for deriving from the triggering circuit and the utilization point, pulses displaced from one another by integral multiples of the delay period. Valve V1, Fig. 1, is connected as a transitron, having a screen feed resistor R1, condenser C1 coupling screen and suppressor grids and resistor R2 between suppressor grid and earth. The anode load R3 is equal to the characteristic impedance of an artificial line connected across it. The remote end of the line is effectively opencircuited being connected through condenser C2 to the suppressor grid of valve V2 which is positively biassed by resistors R4, R5 across the H.T. supply. C2, R5 act as a differentiating circuit. The anode of V1 is coupled to the control grid of V2 through a differentiating circuit C3, R6, the grid being positively biassed by resistors R7, R6, across the R.T. supply. A voltage of saw-tooth wave form a, Fig. 2, from a Miller transitron oscillator is fed to the grid of valve V1, through coupling network C4, R8, R9 which rounds it off to form b. Each cycle produces a flow of cathode current c the valve being biassed back by grid current flow. The resulting anode current takes the form d due to the transitron action in cutting off the anode current for a predetermined period. The negative voltage step at the anode, curve e, is differentiated at C3, R6, applied to the control grid of V2 and produces the first pulse of a group of three, curve f. The negative voltage step also travels down the artificial line, is differentiated by C2, R5 to produce the second negative pulse of the group, curve f, applied to V2. It is also reflected from the open end of the line and travels back to the input impedance R3 where it is absorbed, and produces a second negative step in the anode voltage of V1, curve e. This step, differentiated at C3, R6, forms the third negative' pulse of the group applied to V2. These three negative pulses produce positive pulses at the anode of V2, curve g, which are further shaped by the differentiating inductance in the anode circuit. When the circuit is used as the synchronizing pulse generator for a pulse multiplex system the anode circuit of V2 is common to the valves producing the time modulated channel pulses.
