A machine for printing on the individual sheets of a bound book 14 comprises means for supporting the book 14 with its spine horizontal and its pages horizontal, a page turner which successively turns down the pages for printing and a movable print apparatus. The printing apparatus consists of a bed 16 bearing on an inverted plate and number box, covered on their lower surface with carbon paper or other copying material, and a travelling impression cylinder 25. The bed 16 and cylinder 25 are mounted on horizontal slides, and are moved by linkages from cranks on rotating shafts 18, 19 between the printing positions shown with full lines in Fig. 1 and an inoperative position shown with dotted lines. The book 14 may be a cheque book, with pages which are to be printed on with a magnetic iron oxide. As shaft 10 rotates rubber pad 12 engages the sheets in succession, pushing them laterally free of retaining fingers 6, 8 and spring-loaded button 13. A jet of air from nozzle 7 assists the sheet in moving downwards to position 146, where it is printed on. After printing the sheet falls away to position 14c. Photo-electric control means prevent operation of the printing apparatus when no sheet is in position 14b.

IPC: H01L23/522
Filed: 1964-12-24
Abstract: 1,020,147. Semi-conductor devices. STANDARD TELEPHONES & CABLES Ltd. Dec. 24, 1964, No. 52434/64. Heading H1K. As shown, an integrated tunnel diode logic circuit is produced in a substrate 1 of N-type Ge by etching cavities in the surface, epitaxially depositing a layer of degenerate P-type Ge, and mechanically polishing the surface to form a plurality of separate degenerate regions 3. The tunnel junctions are formed by producing a small region of degenerate N-type Ge in contact with each of the regions 3 either by epitaxially depositing a degenerate N-type layer using a low-temperature process, such as recrystallization from a melt, and etching this layer to produce mesas 5, or by forming cavities in regions 3 and processing as for the degenerate P-type regions but using N-type Ge epitaxially deposited by a low-temperature process. A layer of silicon dioxide or glass is deposited and windows are formed to expose areas of the diodes which are interconnected by vapourdepositing a graded chromium-gold film and then etching to the required pattern. The conductive pattern may also be produced by vapour-deposition through apertures in a mask. The tunnel diodes are isolated, when in use, by reverse biasing the junctions between regions 1 and 3. A resistive film may be vapour-deposited on to the insulating layer and etched to form thin film resistors which are connected into the circuit by the conductive pattern.

Abstract: 1293365 Digital electric calculator KOMBINAT ZENTRONIK VEB 29 Oct 1969 53003/69 Heading G4A Digital data which may include a vulgar fraction expressed as such (e.g. ú2.38¢) is fed into an input register in a calculator by means of an electronic circuit which is energized when the fraction is present and causes its equivalent decimal value to be fed into the input register and which causes a shift of data previously entered when no fraction is present and is fed out of the calculator to a display device by means of a further electronic circuit which in response to the presence of the equivalent decimal value causes the display to display the vulgar fraction and in response to no such decimal equivalent or a zero in the same decimal place causes no display to be made. In an embodiment, Fig. 2, actuation of a key 4 causes two flip-flops 7 and 9 to be set and the equivalent decimal value to be entered in the input register. If the key is not actuated and on the occurrence of signals 16 indicating that the appropriate decimal place has been reached flip-flops 8 and 10 are set and the contents of the input register shifted one place to the left. Signals are supplied to the circuit to indicate the decimal place reached during output from an output printer which is supplied with a printing signal for the vulgar fraction through a set of relays which are switched over when the decimal equivalent of the fraction is not present in the output. A punch tape may be provided in addition to the printer, the data being punched in decimal form for further processing in an external device. The Specification describes the way in which the output system is operated to give a totally decimal output.

Abstract: 1,201,178. Character recognition. INTERNATIONAL BUSINESS MACHINES CORP. 28 Nov., 1967 [23 Dec., 1966], No. 54004/67. Heading G4R. In word identifying apparatus, a plurality of possible characters are stored for each character position of an input word and are selectively combined to form a plurality of possible input words which are compared with stored reference words, there being means for indicating which reference word most probably corresponds to the input word. As described, a character recognition system indicates 3 possibilities for each character of a 5-character word, the 15 possible characters being stored in parallel in character registers at positions depending on whether they are first, second or third choice (as most likely to be correct) for their respective positions in the word. A pulse generator selects each of the 3<SP>5</SP> possible input words in turn and provides its priority defined as the product of its character probabilities these being say 1 for a first choice, 0À9 for a second choice and 0À8 for a third choice. The selected possible word is compared with each of a dictionary of reference words from a magnetic drum until equality, or failing this until all reference words have been tried. On equality, the reference word is gated to an output register together with the product of a probability (stored with the reference word on the drum) and the priority of the possible input word involved, provided this product exceeds that previously stored in the output register. Thus, after all possible input words have been tried, the output register holds the best choice as determined by the character choice priorities indicated by the character recognition system and the intrinsic probability of the word (which will depend on the context).

Abstract: 1,204,666. Polymer/solvent separation. PHILLIPS PETROLEUM CO. 4 Dec., 1967 [5 Dec., 1966], No. 54978/67. Heading C3P. Solid polymer is separated from solvent by subjecting the solution to a zone of reduced 'pressure thereby evaporating the solvent and precipitating the polymer, wherein the overhead vapour stream is treated to recover entrained solid polymer, the treatment comprising condensing the vapour stream by direct contact with a stream of already condensed solvent, recovering a condensed solvent stream containing entrained polymers in solid phase, and separating the solid and liquid phases. The stream of condensed solvent to be recycled is preferably passed through an external cooling means. The solution, which may be of a homo- or copolymer of a 1-olefin in a C 3 -C 12  paraffinic hydrocarbon at a concentration of 20-50% by weight of polymer, can be initially at a pressure of 100 p.s.i.g. and temperature of 100-500‹ F., and can be subjected to a reduced pressure of 5-40 p.s.i.g. The initial solution before passing into the zone of reduced pressure, may be fed through a gas liquid separator to remove unreacted monomer. An apparatus, suitable for the above process, is shown in the figure. The polymer solution leaves the reactor 10 by effluent line 18, and passes to a flash chamber 22 where solvent is removed under reduced pressure and temperature conditions. The solid polymer is removed via the conduit 28, and additionally may be stripped of solvent by the passage of steam through the conduit 29. Solvent vapours containing entrained polymer particles, pass through 26 to the condenser 30 containing a vapour-liquid contacting means 32 such as a sieve or bubble-cap trays, and packing 34 for coalescing entrained liquid droplets and these vapours are contacted with cooled condensed solvent which has been withdrawn from the lower section of the condenser column via 38, and passed through a heat exchanger 40 where it is cooled, and then returned to the column above contacting means 32. Liquid solvent is withdrawn from the bottom of the condenser via the line 48 and passed to a phase separator or other equipment for recovery of solvent. The liquid phase copolymerization of ethylene and butene, using a catalyst comprising silica-alumina impregnated with chromium oxide, is exemplified.
