IPC: H01R12/51
Filed: 1968-06-18
Abstract: 1,228,651. Printed circuits. TELEFUNKEN PATENT VERWERTUNGS G.m.b.H. 18 June, 1968 [28 June, 1967], No. 28876/68. Heading H1R. A method of manufacturing a multilayer printed circuit board having at least four layers of printed circuitry comprises the steps of: making similar holes in corresponding positions in a plurality of insulating support plates 1 having metal-clad surfaces; depositing metal on the surfaces of the holes to line the holes; forming required printed circuits in the metalclad surfaces which when the pack is assembled form internal surfaces of the pack; applying adhesive layers 11 to the surfaces of the plates 1, stacking the plates 1 so that the holes therein are aligned and allowing the adhesive to set; removing any surplus adhesive 12 from the holes; depositing another coating of metal on the surfaces of the aligned holes over the original lining to form a through connection through the pack; and forming required circuit patterns from the two metal clad surfaces constituting the outer surfaces of the pack. Each support plate 1 is made of larger dimensions than the finished article so as to leave a margin and after stacking the plates guide holes are drilled simultaneously through all the margins of the stack. The plates are thus held in register by guide pins passing through the guide holes during drilling of the holes to be plated through the pack. The plates are then disassembled for the plating through and formation of the printed circuits. A mounting jig having pins 7 is then employed for the permanent stacking and insulating sheets 8 may be inserted between neighbouring plates. The circuit patterns may be reinforced by an electroless deposition of tin.

Abstract: 1,228,692. Typewriters. ZBROJOVKA BRNO NARODNI PODNIK. 19 March, 1969 [28 March, 1968], No. 14352/69. Heading B6F. Line-count control.-A line counting device counts a preset number of lines before causing the typewriter to lock at the end of a page, but only begins to count when the end (i.e. absence) of the page is sensed by a detecting means. Prior to the page end being sensed, the line counter is reset to zero after each line spacing operation. The typewriter shown in Fig. 4 has a known positive-feed, variable-width, linespacing mechanism which includes a reciprocating pawl 241 normally engaged with a ratchetwheel 211 clutched to the shaft 2101 of the platen 210. The line counting device includes a cam 212 rotatably mounted on this shaft 2101, and having around part of its periphery ratchet teeth 2121 which are also engaged by the pawl 241. In operation, reciprocation of the pawl 241 in the Y and X directions results in the stepping of the ratchet-wheel 211, platen 210 and line counting cam 212 by the same angular amount. However, the cam 212 is not retained in this stepped position by its retaining pawl 2701, since with the movement of the pawl carrying slide 240 in the X direction, a protrusion 2402 trips via a pivoted link 271 the lever 270 of the retaining pawl 2701, thereby allowing a torsion spring loaded pinion 290 meshing with the cam teeth 2121 to return the cam to its original starting position. The counting device is allowed to count the last preset number of lines at the bottom of a page when the trailing end of the page moves out from between sensing plates 2055 and a two-part guiding plate 21a, 21b. This allows the detecting means 205 to pivot downwards about shaft 22 so that its extension 2051 allows the pivoted lever 271 to drop out of the path of the slide protrusion 2402. From this point on, movement of the slide 240 in the X direction will not reset the line counting cam 212 to zero. With each succeeding linespacing operation, the cam 212 will rotate an increment until the pawl 241 rides up on to the cam surface 2122 by pivoting about shaft 2411. The pawl 241 is therefore moved out of engagement with the ratchet-wheel 211 so that no further line spacing is possible, and furthermore, an extension or nose 2412 on the pawl 241 will move into the path of a locking lever 280 which causes a locking stop 284 to mesh with the typewriter space bar rack 11. No further typing is therefore possible until the paper is removed and the line-counter cam 212 reset to zero by manually pivoting the retaining pawl lever 270. The capacity of the counting device, which represents the distance between the last line and the bottom edge of the sheet, is set by moving the adjustable stop 220.

Sliver cans are transported continuously between a drawframe D and a flyer frame F in an arrangement comprising a plurality of trolleys 1-55 each of which carries a plurality of cans in a line and a means for guiding the trolleys successively through a coiling station 60 from a supply station on one side and a discharge station on the other so that each can in turn is brought beneath a coiling unit. The flyer frame F is in front of and to one side of the drawframe D and has its longitudinal axis parallel to the path of the trolleys through the coiling station 60. A first conveyor CH1 is arranged behind the flyer F to move trolleys with empty cans (the sliver having been used by the flyers) from the rear of the flyer F to a transfer station T. At T they are disengaged from the first conveyor and picked up by a second conveyor CH2 and brought into cooperative relation with a trolley indexing mechanism for moving the trolleys through the coiling station 60. As shown, the trolleys are set up in a plurality of blocks of trolleys behind the flyer frame F. In front of and behind the trolley blocks there are inclined paths sloping away from the trolleys, the trolleys carrying cams containing sliver (shown as heavy circles) rest against rail 56. Trolleys carrying empty sliver cans (shown as light circles) are moved manually from the blocks onto the front inclined path against rail 59 to be picked up by conveyor chain CHI. One conveyor chains CH1, CH2 are controlled by microswitches. The trolleys are moved through the coiler 60 by pneumatic jacks.

Abstract: 1,256,710. Neutralizing sulphonated olefins and sulphated alcohols. R. J. BROOKS, and B. BROOKS. 13 Dec., 1968 [29 April, 1968], No. 59492/68. Heading C2C. A continuous process for the production of detergent α-olefin sulphonates or unsaturated alcohol sulphates comprises (1) continuously sulphonating an α-olefin, especially a C 12 -C 20  α-olefin, or sulphating an unsaturated alcohol having at least 10 carbon atoms, in a single stage by contacting a thin flowing film thereof, e.g. at 90‹ to 120‹ F., with a mixture of sulphur trioxide and air, subject to the proviso that when an α-olefin is sulphonated the molar ratio of SO 3  to α-olefin is from 1À10:1 to 1À25:1 and (2) continuously heating the sulphonated or sulphated product with a neutralizing agent, e.g. NaOH or KOH, the heating being carried out in the case of the α-olefin sulphonated product either in two stages, viz. 110-130‹ F. and 190-310‹ F. respectively or in a single stage at 180-240‹ F. and in the case of the unsaturated alcohol sulphated product at 200-220‹ F. The sulphonation product is preferably digested for 1 to 5 minutes before the neutralization step, the digestion assisting in the elimination of the hydroxy sulphonates probably through rearrangement of the sultone also formed in the sulphonation. The neutralizing agent is preferably used in a molar ratio of 1À02 to 1À05 mols. per mol. of sulphonic acid groups. The neutralized sulphonated olefin is generally finally hydrolysed under alkaline conditions, e.g. at 190-310‹ F., to decompose the sultone present and after hydrolysis a suitable sulphonic acid or sulphuric acid may be added to the sulphonate to adjust the pH to a value, e.g. pH 6 to 10, useful in detergent formulations. A flow diagram is given and the process is exemplified by the sulphonation of a C 15 -C 18  α-olefin mixture and subsequent neutralization and hydrolysis with NaOH and by the sulphation of sperm alcohol and neutralization of the product.

Abstract: 1290229 Voice-immunity circuits STANDARD TELEPHONES & CABLES Ltd 12 March 1970 11834/70 Heading H4R In-band, repetitively-interrupted tone signals are discriminated from speech by a counter circuit which counts up to a predetermined number of tone bursts before accepting that the tone signal is genuine and which is reset to zero whenever a selected frequency occurs simultaneously with the tone signal. The counter comprises a capacitor which is incrementally charged up to a stabilized reference level by each tone burst and which is instantaneously and completely discharged upon any occurrence of the selected frequency. If the capacitor charge reaches the reference level a comparator is effective to enable a signal receiver. The circuit comprises an active, low-pass filter 21 tuned to the frequency of the tone signal and a band pass filter 26 tuned to 1 KHz i.e. the maximum speech power frequency, both of which filters are included in the collector path of a signal input amplifier 41. In the presence of an interrupted tone, filter 21 produces a sinusoidal output which is converted into a square-wave by a Schmitt trigger 49, 50 and then applied via a linear pump 52, 53 to a capacitor 23. Provided no 1 KHz signal is present transistor 55 remains off so preventing capacitor 23 from discharging rapidly through resistor 56. When the charge on capacitor 23 reaches the level defined by Zener diode 61, transistor 59 conducts so as to enable an associated signal receiver.
