Title: Process for the production of stannosiloxanes
IPC: C08G77/00
Filed: 1960-07-05
Abstract: A stannosiloxane is made by reacting a hydrocarbono-tin oxide with a hydrocarbonosiloxane at 50 DEG  to 300 DEG C., preferably in the presence of an alkali metal hydroxide catalyst.  The siloxanes used may be stable oils consisting, e.g. of straight chain dialkylsiloxane units, alkyl hydrogen siloxane units or alkyl alkenyl siloxane units or copolymerized dialkyl and diaryl-siloxane units with chainstopping trialkylsiloxane units or siloxanes of the formula <FORM:0903434/IV(a)/1> , wherein n is an integer, R and R1 are hydrocarbon radicals.  In a modification the organotin oxide is added to the starting siloxanes used for making the stable oils, e.g. to a mixture of octamethyl-cyclotetrasiloxane, hexamethyldisiloxane and potassium hydroxide.  If desired, the high polymeric stannosiloxane may be depolymerized to form an oil of lower viscosity by mixing it with hexamethyldisiloxane and heating. Examples are given.  Uses: As catalysts and stabilizers in the production of foam material based on isocyanates.

Title: Improvements in or relating to electrical analogue calculating arrangements
Inventor: UDALL ANTHONY JOHN SHAWCROSS
IPC: G06G7/186
Filed: 1963-06-14
Abstract: 1,088,842. Electric analogue calculating. ELECTRIC & MUSICAL INDUSTRIES Ltd. June 9, 1964 [June 14, 1963], No. 23727/63. Heading G4G. An arrangement for producing a rectangular waveform whose duty factor is proportional to the time differential coefficient of an input signal, consists of a rectangular wave generator A (Fig. 1), an integrating circuit C coupled to receive the output of the rectangular wave generator and an arrangement D to combine the output of the integrator with the input signal and apply the combination to the generator A. The generator provides the output signal having the required duty factor. The arrangement may be utilized in a generalized integrator, which provides the integrals of functions with respect to variables other than time, and may also be used in providing a multiplier. As shown in Fig. 2, which indicates the overall circuit arrangement of a generalized integrator, the generator A of Fig. 1 may consist of a bistable valve circuit (triodes 3 and 4), the output of which is passed to a cathode follower 5, thence to a limiting arrangement 6-10 and thereafter to an integrator 11, 12, 13. The output from the integrator is added to the input x and controls the state of the bi-stable. In the absence of the input x, a square wave output with a 1: 1 duty cycle will be obtained from the bistable. If however x changes, the change is superimposed on the output voltage from the integrator, and the duty cycle of the generator output alters. It is shown in the Specification that the duty cycle will be proportional to dx/dt This rectangular waveform with a duty cycle representing dx/dt is amplitude limited by the diodes 16 and 20 to +y, a voltage proportional to y being supplied to the input 15. The average waveform now represents y . dx/dt and is passed to the integrator 22. 23. 24 which yields an output A method of carrying out multiplication using the identity incorporates two arrangements according to the invention. The terms in α are introduced into the identity to enable drift stabilization to be achieved. In Fig. 3 the components A 1 , B 1 , C 1 , D I , E 1  and A 2 , B 2 , C 2 , D 2 , E 2  constitute two differentiating circuits similar to that of Fig. 1, operating respectively on the inputs x and y. The integrators C are modified from that of Fig. 1 by having a feedback resistor 33 which feeds back part αx or αy of the integrator output to the input. The outputs from the differentiating circuits are thus rectangular waves having duty cycles proportional to (dx/dt + αx) and (dx/dt + αy) respectively, and these outputs are passed to the limiters B 3  and B 4 , where the waves are limited in accordance with x and y respectively to provide outputs of average value y(dx/dt + αx) and x(dy/dt + αy). These are added and passed to the modified integrating circuit C 3 , where a proportion 2α of the output is returned to the input, to provide an output which, taken over an adequate time interval, is proportional to xy.

Title: Method and means for transcribing ideographic or other non- alphabetic characters
IPC: B41J3/01
Filed: 1972-05-19
Abstract: 1398882 Printers C LEBAN and L STANGER 19 May 1972 23790/72 Heading G4H [Also in Division B6] An ideographic or other non-alphabetic character is represented using a plurality of symbols each defining at least one element of the character and a plurality of synbols each defining a juxtapositional relationship between elements of the character, the symbols being decoded to determine the identity of each element and the position of one element relative to another, the decoded symbols being transformed into an assembly sensible as a character. A Chinese character is entered on an alphanumeric keyboard by entering a numeral identifying the gross morphology followed by a series of vowel-consonant pairs, each pair identifying an element of the character. Elements with the consonant first in the pair are generally characterized by left orientation, horizontally, orthogonality and those with the consonant second are generality characterized by right orientation, vertically, slantness. The vowel indicates relative position in the character field. The entry of elements is in a standard order with respect to position, containment and overwriting relations, but with a most important element (that having a certain position depending on the particular gross morphology) first. Other symbols are also keyed in to define the character. The elements selected are displayed on a CRT in an optical photographic printer, the sizes and positions of elements being adjusted as successive elements are entered. Two apparatuses as above may control each others printers as well as their respective printers. Storage may be provided between the keyboard and the conversion circuitry. An alternative printer uses a row of type-wheels, each having a respective element in various sizes, the row being shifted longitudinally to select the element and rotated to select the size (the latter according to the identity and total number of the elements in the character). The paper is moved in two dimensions to effect positioning within the character area.

Title: Low temperature graphite radiation damage removal
IPC: G21C5/08
Filed: 1963-06-17
Abstract: The dimensional growth in the graphite care of a nuclear reactor caused by exposure to low temperature nuclear radiation is removed by annealing the graphite by subjecting it to frequent intervals of heating at temperatures up to 250 DEG  C., alternating with periods of radiation that produce dimensional growth only up to the amount removed by the respective subsequent heating intervals. By this means, the progressive accumulation of large amounts of radiation damage, the fast release of stored energy from the graphite and oxidation of the graphite are prevented. The heating may be at 150 DEG  C. and the radiation during each period 15 megawatt days/adjacent ton of uranium (MWD/AT), where 1 MWD/AT is 7 x 1016 n.v.t. for neutrons with energies greater than 0.6. Mev. Each period of radiation may produce a positive length change in the graphite of only up to about 0.0075% at irradiation temperatures of between 20 DEG  to 40 DEG  C. Large amounts of initial radiation damage can be sequentially removed from the graphite by removing more radiation damage during the heating intervals than is caused by the respective preceding radiation periods.
