Title: Improvements in or relating to high-speed printing apparatus
IPC: B41J2/43
Filed: 1966-09-07
Abstract: 1,118,068. Selective printing. SIEMENS A.G. 7 Sept., 1966 [8 Sept., 1965], No. 39963/66. Heading B6F. In a printing device in which characters are formed serially on an intermediate carrier 1 and are transferred line-by-line on to a second sheet 7, the printing hammers 8 are operated independently of one another in dependance upon the number of character positions occurring in that particular line and which are registered by a counting device during the formation of the characters on the intermediate carrier 1. The characters may be formed electromagnetically or electrostatically, or by ink-jets passed through an electrostatic deflection system. The carrier in this case comprises a synthetic tape. An auxiliary electrode 11 or permanent magnet at the rear of the record 7 holds the ink on to it. Alternatively a dampener 12 holds the ink to the record 7. After a line of characters is transmitted and received by the printer a code (twice carriagereturn and line-spacing) is received. This occupies three letter-positions only so that entry space on the intermediate tape is thereby saved; the counter causes only the requisite number of print hammers to be operated. Each hammer controls printing in three letter-spaces. This is necessary to allow for the carriage-return and line-spacing signals to be received before impression is effected. It also simplifies the counting mechanism.

Title: Improvements relating to data transmission apparatus
IPC: H04L25/08
Filed: 1965-09-20
Abstract: 1,104,103. Data transmission systems; transistor amplifier circuits. INTERNATIONAL BUSINESS MACHINES CORPORATION. 20 Sept., 1965 [1 Oct., 1964], No. 39979/65. Headings H3T and H4P. Double current signals pass over a line from a transmitter to a receiver both of which comprise differential amplifiers. Input signals at 45 are amplified and pass to differential amplifier 50, 51. The outputs, which are double current signals and have opposite senses, are applied to transistors 1, 2 and 20, 21 which are of opposite conductivity type. Thus, when the output of 50 is positive and that of 51 is negative, transistors 2, 21 will be off and 1, 20 will be on, giving positive and negative signals at terminals 12, 31. At the receiver, differential amplifier 62, 63, fed by constant current source 71 provides signals which pass via amplifier 66 and emitter follower 90 to the output. The apparatus is insensitive to supply voltage variation and to line earth shifts.

Title: Telecommunication switching matrix
IPC: H04Q3/00
Filed: 1969-08-12
Abstract: 1285180 Automatic exchange systems CSELT-CENTRO STUDI E LABORATORI TELECOMUNICAZIONI SpA 12 Aug 1969 [13 Aug 1968] 40259/69 Heading H4K In a relay switching matrix, the application of operate voltage/current to a relevant row and column is effected by respective SCR's which are turned-on by the simultaneous application of a control signal that is unique to each and a common control signal. Once the crosspoint relay has operated, it is held-on over a hold winding by another SCR, the original SCR's being turned-off. Particularly low current consumption as is required at a satellite exchange is achieved by the arrangement. In the Fig., only the operate and hold windings Ahk, Hhk of a single relay having the row and column co-ordinates h, k is depicted. In order to operate this relay a control logic supplies negative, positive and zero pulses simultaneously to terminals ar, ac and r respectively. Of these, the negative pulse has no effect until it ceases whereupon a positive pulse occurs across resistor R2 thus turning-on the row selection diode SCR1 which thereby effectively applies - E to the row wire pertaining to the wanted crosspoint; the positive pulse after inversion in gate P turns on transistor Q1 which in combination with its emitter resistor R7 acts a current generator to supply current to resistor chain R4, R5, R6. Thus turning-on column selection diode SCR2 which thereby effectively applies earth (via Q4) to the column wire pertaining to the wanted crosspoint; and the zero (instead of normal +E) pulse turns-on Q3, Q4 and Q5 which allow holding current to flow for SCR1, SCR2 and Q1. With Ahk operated, it is held-on over its hold winding Hhk by the firing of SCR3 (which occurs subsequently to turn-on of SCR2 thanks to capacitor C3). When the zero potential on r is replaced by + E all the diodes and transistors (with the exception of SCR3) turn-off, the diodes D1, D2 protecting SCR1, SCR2 from overvoltages caused by the inductance of the relay. In order to release the crosspoint, a positive pulse is applied to terminal d thus turning-on Q2 so as to shunt SCR3 which thereby turns-off being protected against transients by diode D5. It should be noted that as long as SCR3 is on, no further operate voltages for this column will have any effect since gate P is closed over resistor/diode, R8/D4.

Title: Purification of glyceride oils
IPC: C11B3/06
Filed: 1961-11-14
Abstract: A process for continuously refining lightcoloured lipoid B-containing crude glyceride oil comprises (a) continuously adding a mixture of aqueous sodium carbonate and sodium hydroxide solutions to a stream of the crude oil, the sodium carbonate solution being added in an amount which is sufficient to prevent any evolution of carbon dioxide gas and which is greater than 2 molar equivalents for each mole of free fatty acid present in the crude oil, and the sodium hydroxide solution being added in an amount which is sufficient to reduce the phosphatide content (calculated as phosphorus pentoxide) of the refined oil to between 3-30 parts per million, (b) subjecting the mixture to shearing forces equivalent to turbine tip speeds of at least 850 feet per minute, preferably at least 1500 feet per minute, for at least 15 seconds, (c) allowing the combination to stand, and/or to be subjected to shearing forces for a time such that the total time of steps (b) and (c) is at least 1 minute, and (d) separating refined oil by centrifuging the resulting mixture.  It is preferred that the amount of sodium carbonate be within the range 3-5 molar equivalents for each mole of free fatty acid present in the crude oil and that the solution has a concentration of 16-28 B<\>e; the sodium hydroxide used generally comprises 0.0004-0.004 times the weight of the crude oil, and is generally employed as a solution having a concentration of at least 16 B<\>e, preferably 18-30 B<\>e, the amount of hydroxide used being sufficient to reduce the phosphatide content of the refined oil (calculated as phosphorus pentoxide) to 5-25 parts per million. The weight of sodium hydroxide added per unit weight of the crude oil may be in the range 1/2 W to 1 1/2 W, where W = 0.0935 A + 0.00063, and A = weight of acetone insolubles per unit weight of oil.

Patent GB-409270-A (GB)
Abstract: 409,270. Colour photography. GASPAR, B., 38, Innsbruckerstrasse, Schoneberg, Berlin. July 19, 1932, No. 20423. Convention date, July 29, 1931. [Class 98 (ii).] Multicolour photographic copies are produced upon a plurality of superposed, coloured silver halide layers sensitive to different colours, such as described in Specification 408,991, by copying from a lenticular master negative or diapositive, the selection filter sectors being replaced by filter sectors of which that intended for the undermost layer allows the passage of infra-red to which that layer is sensitive ; the other two filter sectors are each coloured with a primary colour adapted to the spectral perviousness of the coloured copying layers. In a preferred arrangement, three superposed layers, coloured respectively yellow, purple-red and blue-green, and sensitive to green, red and infra-red, the yellow layer being uppermost, are copied with the aid of green, red and infra-red filter sectors, the green and red sectors being impervious to infra-red. The sequence of the coloured layers may be varied, e.g. blue-green, yellow and purple-red. Exposure may be made through the different sectors separately and for appropriate times; or exposure may be made simultaneously through all filter sectors followed by supplementary exposures through appropriate sectors. The appropriate exposures are determined by exposing multi-layer material below a graduated scale and below filters corresponding to the layers. The invention may be applied to two-colour pictures and to kinematograph or paper pictures. Specification 343,369 also is referred to.

Abstract: 1,021,260. Projectile fuzes. K. DIEHL. Oct. 8, 1964 [Oct. 15, 1963], No. 41006/64. Heading F3A. An electrical fuze, for projectiles, has as an ignition voltage generator a piezoelectric cell 5, Fig. 1, which is struck by an arm 11 released by a trigger 14, Fig. 2, during acceleration of the projectile. Inertia forces cause the trigger 14 to move downwardly against a spring 21 to release the arm 11 which is swung about a pivot 10 by a spring 16, a hammer 12 striking the cell 5 through a baffle-plate 4 having a sound resistance equal to that of the cell. The electrical charge due to compression of the cell is dissipated through a diode 38 while that of reverse polarity due to expansion is retained. At the end of the period of acceleration, the spring 21 moves the trigger 14 upwardly to release a second arm 24 which is swung about a pivot 23 by a spring 32 to complete an electrical circuit containing the cell, a detonator 79 carried by the arm, and an impact switch 80. If due to a fault, the impact switch is closed before the arm 24 is swung into ignition position contacts 25<SP>1</SP>, 35 discharge the cell. A strap 44 provided with a fastener 45 holds a ball 43 in a notch of the device 14 until the fuze is to be made live. A spring 39 engages a recess 40 to hold the arm 24 in the ignition position. In Fig. 4, a spring- loaded plunger 57 energizes the cell 5 when locking balls 60 are released by an inertia-actuated member 62 while in Fig. 6 energization is provided by a shock wave from a detonator 67 which is punctuated by a firing-pin 70 on discharge. To provide a time delay in operation of the trigger 14, it may carry a spring-loaded member having a pair of fingers to engage a transversely-corrugated pin.
