Title: Video data bit selection and storage
IPC: G06V30/10
Filed: 1971-07-05
Abstract: 1313965 Character recognition INTERNATIONAL BUSINESS MACHINES CORP 5 July 1971 [20 July 1970] 31353/71 Heading G4R In a character reognition system a field containing a character is scanned and the video signal is processed to reduce the number of bits which are passed to the recognition unit. As described the field, Fig. 2a, is scanned from bottom to top in successive scans from right to left. A counter is incremented by clock pulses at the video bit rate, the counter being reset to zero at the start of each scan. The output of the counter is compared with a count derived during the preceding scan. When equality is detected all video bits occurring subsequently in the scan are stored. The effect of this operation is to distort the character and to reduce the height and breadth of the effective field, Fig. 2b. The field is scanned by a c.r.t., reflected light passing to a photo-multiplier which provides video signals on line 111, Fig. 1. The signals pass to gate 151 and detector 110. Detector 110 may comprise a shift register having a parallelbit output connected via weighted resistors to a threshold unit, Fig. 3 (not shown). Such an arrangement ensures that a signal is generated on line 115 only on detection of a certain number of sequential black bits, representing part of a character, and eliminates noise. The output of detector 110 sets bistable 123 if not already set. The bistable triggers monostable 125. At the start of each scan bistable 123 is reset and counter 131 is reset to zero. The counter is incremented by video bit rate clock pulses and when monostable 125 is triggered the output of the counter is gated to store 141 whose ouput is compared with the current output of the counter. When equality is detected bistable 123 is set, if not already set. The triggering of monostable 125 causes a 1-bit to be read in to the first stage of shift register 159 which is stepped by the video clock pulses. The output of register 159 controls the read-in to store 155 of the video-bits occurring at, and subsequent to, the setting of bistable 123. Thus in the third scan, Fig. 2a, black bits 13, 14 are placed in stages 1, 2 of store 155, and in the fourth scan black bits 11-14 are placed in stages 1-4, and so on, as indicated in Fig. 2b. In scan 11, store 141 will contain a count of 3. Thus, in the following scan 12, comparator 139 will set bistable 123 when counter 131 reaches 3, i.e. one white bit prior to the first black in this scan. Consequently bits 3-7 are read in to stages 1--5. Store 141 is again set to 3 and so in scan B bits 3-9 are read in to the store, and so on. At the end of each scan store 155 is read out to shift register 167, which can be read out to the recognition unit at a lower rate than that of the video clock pulses.
Patent GB-890268-A (GB)
Title: Improvements relating to the production of cyanogen halides
IPC: C01C3/00
Filed: 1960-09-12
Abstract: Cyanogen chloride and bromide are prepared by bringing the appropriate halogen and nitrogen into contact with carbon at a temperature of 1800 DEG  to 3600 DEG C., quenching the product gases to 500 DEG C. or below and condensing and separating the cyanogen halide formed.  A suitable type of reactor consists of a jacketted quartz (or alumina or other refractory material that is inert towards the halogen and its reaction products with carbon and nitrogen at the required reaction temperature) tube enclosing an electrically heated graphite rod.  On a large scale, an electric resistance furnace or an electric-arc furnace containing a fluidized or stationary bed of carbon particles may be used.  In a fluidized carbon-bed reactor, graphite, other forms of carbon, alumina or other inert refractory material may be used as the materials of construction. Non-electrical heat sources, e.g. construction reactions and focused solar heat rays may also be used.  The carbon used may be in the form of bars, filaments, rods or beds of particulate material having any shape.  The halogen used in the process must be free from impurities such as H2, O2, H2O and other compounds containing H2 or O2, which would preferentially combine at the reaction temperature with the halogen or carbon.  The nitrogen must also be free from reactive impurities.  The carbon and halogen may be formed in situ from compounds thereof, e.g. CCl4, tetrachloroethylene, and hexachloroethane, decomposing at the reaction temperature. The reaction temperature is preferably between 2400 DEG  and 3000 DEG C., and pressures between 0,1 and 3 atmospheres are preferred.  The nitrogen/halogen ratio (by volume) should be between 2:1 and 3:1 when the reaction temperature is between 2400 DEG  and 3000 DEG C., and 1:1 when the range is 1800 DEG  to 2400 DEG C.  The carbon that reacts to form the cyanogen halide is in the gas phase, the amount of carbon present being in considerable excess of the amount needed for the reaction.  The time of contact of the reactants must be long enough for equilibrium to be attained at the reaction temperature, and after this the gaseous products are quenched to 500 DEG C. or below in from 1 to 10 milliseconds.  The quenched gases are further cooled and the cyanogen halide collected, unreacted nitrogen and halogen being recycled.  In Example 1, the graphite heating element is heated to 2700 DEG C. and the molar ratio N2:Cl2 is 2,3:1, the reaction time being 40 to 45 minutes.  Example 2 is similar, the reaction time being 145 minutes at a temperature of 2850 DEG C.  In Example 3, a bed of graphite heated to 2600 DEG C. is used.

Title: Process for polymerizing alpha-olefins
IPC: C08F10/00
Filed: 1962-08-20
Abstract: Titanium trichloride is made from triethyl aluminium and titanium trichloride in molar ratios 0.4 to 0.5\sS1 in inert hydrocarbon solvents by adding a AlEt3 solution having a concentration of 80 to 120 g./l. to a TiCl4 solution having a concentration of 200 to 300 g./l. at - 20 DEG  to + 30 DEG  C. and then heating to 145-155 DEG C. for 30 to 120 minutes.  A large number of suitable hydrocarbon solvents is specified and if their boiling point is below 155 DEG C., the second stage of the reaction is carried out under pressure. The product may be recovered by centrifuging the suspension or by evaporating the solvent, and may be used either in suspension or as a solid in the polymerization of an ethylenic monomer (see Division C3).ALSO:A novel product (a), and its use is claimed as an a -olefin polymerizing catalyst component, is obtained as a reaction product from triethyl aluminium and titanium tetrachloride in molar ratios between 0.4:1 and 0.5:1, by adding an Al Et3 solution having a concentration of 80 to 120g/l to a TiCl4 solution of concentration 200 to 300g/l at -20 DEG  to +30 DEG C., then heating to 145 DEG  to 155 DEG C. for 30 to 120 mins. and optionally removing the votatile matter. Aliphatic a -olefins preferably propylene or butene-1, are polymerized with a catalyst comprising either the suspended or solid product above and 1 to 4 mols./mol. of TiCl3 of a C1 to C5 dialkyl aluminium monohalide. The solvents which may be employed are inert hydrocarbons which may be saturated aliphatics, cycloaliphatic, aromatic or arylaliphatics.  The intrinsic viscosity and apparent density ranges of the polypropylene are different when the product (a) is used in suspension to prepare the catalyst, or when the dried product is used.  The effect of varying catalyst concentration, polymerization temperature and pressure on the polymer are illustrated in the examples, in which product (a) is obtained by the use of AlEt3 containing small amounts of (Et)2Al OEt.

Abstract: 303,148. Akt.-Ges. der Maschinenfabriken Escher, Wyss, et Cie. Dec. 30,1927, [Convention date]. Systems for alternating-current motors.-In an arrangement for automatically starting and stopping a single-phase motor driving a refrigerator, a thermal switch T<1> subject to the temperature of the refrigerating-chamber closes, through an electromagnet R<2>, a mercury switch S<2> which connects the supply leads 1 to the motor -stator winding H : an auxiliary phase Z is temporarily switched in by an electromagnet R<3> acting on a mercury switch S<3>. The motor thus starts and accelerates to a speed at which the auxiliary phase is switched out as a result of decreased current in one winding W<3> of the magnet R<3>, on opposed winding W' in series with the auxilary phase contributing to the effect. If the starting period persists too long, a thermal switch T<2> with an upper contact 44 closed by the heating action of the starting resistance U energizes R<1> which breaks the current of the magnet R<2> and so opens the motor stator switch S<2>. The mercury column in the thermal switch T<2> must fall below a lower contact 43 before the relay is de-energized and the motor switch reclosed. The thermal switch T<2> may be heated by the motor windings or iron parts, or by choking coils or condensers of starting apparatus; an automatic switch dependent on the current strength may be used in place of or in addition to the switch T2.
