Title: Improvements in and relating to autographic registers
IPC: B41L5/08
Filed: 1935-02-01
Abstract: 435,516. Memorandum appliances. UNITED AUTOGRAPHIC REGISTER CO., 5000, South California Avenue, Chicago, U.S.A. Feb. 1, 1935, No. 3379. Convention date, Feb. 2, 1934. [Class 16] An autographic register comprises a frame having a platen over which a plurality of stationary strips provided with register perforations may be led, a yieldingly urged pin adapted to engage the perforations in the strips to arrest the advance thereof, a tear-off blade near the front of the platen whereon the strips may be severed, and a feed device for initially advancing the strips comprising a rotatable feed member mounted to engage frictionally the strips and to advance them, and means for automatically retracting the pin from engagement with the strips upon rotation of the feed member and prior to the advancing of the strips. The portable register shown may be made of aluminium, and comprises a casing A having a top wall A<2> serving as a platen, a carbon-roll holder A' from which carbon papers are drawn transversely of the register, and a skeleton cover B to which is secured at its front end a tear-off bar B<1>. Zig-zag folded stationery is passed out of the casing over the platen, and is registered by two register pins which engage perforations therein. The register pins are mounted on leaf springs 13 on the underside of the platen, and are pressed through apertures in the platen beneath the tear-off bar B<1>. An initial feed device C, which is preferably used to start the feed of the stationery only, comprises a transverse shaft 20, mounted beneath the tear-off bar, provided with a mutilated feed roll 21 having a flat portion 22, and a pair of cams 23 also having flat portions which engage depending arms 25 connected to the leaf springs 13. Near the centre of the tear-off bar is rotatably mounted a knurled presser roll 19. The cams 23 and feed roll 21 are so arranged that during rotation of the shaft 20 by a knob 27, the cams retract the register pins through the medium of the arms 25 just prior to the feed roll 21 coming into engagement with the stationery and pressing it against the presser roll 19 to commence a feeding operation. A further cam 30 on the shaft 20 has a flat face and is engaged by a leaf spring 15. When the spring 15 engages the flat face of the cam 30 it tends to retain the shaft 20 in the position in which the flattened portion of the feed roll 21 is presented to the presser roll 19, and the register pins are permitted to spring upwardly by the cams 23.. After the initial feed, the stationery is grasped and pulled by hand until the register pins engage the next set of perforations.

Abstract: 1,089,841. Programme control of movement. LING-TEMCO-VOUGHT, Inc. Jan.30, 1964, No. 4080/64. Heading G3N. In an aircraft flight control system, a dead reckoning inertial guidance system is corrected by determining the craft instantaneous position and comparing this with the required location to provide a correction signal for the guidance system. A storage system contains information regarding the altitude profile of the area over which it is proposed to fly the aircraft. Altitude profile measurements are taken of the land directly beneath the craft and these are compared with the stored information to provide the vehicle instantaneous location. Craft altitude is obtained by radar and the spacing of the sampling points is adjusted in correspondence with craft speed to maintain equality with the storage spacing. The comparison of the altitude measurements and the stored altitudes is effected by either the "mean square difference" or "mean absolute difference" methods from which the minimum error function identifies the instantaneous craft position.

Title: Organosilicon polymers
IPC: C08G77/00
Filed: 1958-02-10
Abstract: The novel compounds are polymers of the unit general formula: <FORM:0846978/IV(a)/1> where each R is an aryl, alkyl or cycloalkyl radical and X is CF3CH2CH2-, <FORM:0846978/IV(a)/2> a cyclobutyl radical of the formula <FORM:0846978/IV(a)/3> or <FORM:0846978/IV(a)/4> , or copolymers thereof comprising from 0,1 to 99,9 mol per cent of the above compound and from 99,9 to 0,1 mol per cent of a siloxane of unit general formula <FORM:0846978/IV(a)/5> where each Z is a monovalent hydrocarbon or halogenated hydrocarbon radical and m is 1, 2 or 3.  The compounds can be made by reacting a silane of the formula <FORM:0846978/IV(a)/6> wherein Y is a hydrolysable radical, with a vinyl Grignard reagent to form a divinyl silane which is subsequently reacted with a symmetrical tetraorganodisiloxane, preferably in the presence of a platinum catalyst at 150 DEG  to 175 DEG C.  The pre ferred method is by reacting the divinyl silane, obtained as above, with the silane <FORM:0846978/IV(a)/7> to form the silcarbane <FORM:0846978/IV(a)/8> which is then hydrolysed and condensed to yield the required silylethyl siloxane polymer.  An alternative method is to react the silane <FORM:0846978/IV(a)/9> with the silane <FORM:0846978/IV(a)/100> and hydrolyse and condense the resulting reaction product.  If desired the <FORM:0846978/IV(a)/111> silanes may first be condensed to disiloxanes and then reacted with <FORM:0846978/IV(a)/122> to give the desired polymers.  Inert solvents may be used in the above hydrolyses.  The copolymers are made by conventional methods.  In a typical Example (1) a vinyl Grignard reagent was reacted in tetrahydrofuran with trifluoropropylmethyldichlorosilane to give the corresponding divinylsilane which was then reacted with sym-tetramethyldisiloxane at 150 DEG  to 175 DEG C. in the presence of platinum on charcoal. The product was a liquid polymer of the unit formula: <FORM:0846978/IV(a)/133> Uses: as lubricants, coatings, elastomers and moulding resins. Specification 760,201 is referred to.
