Title: Phase discriminator for synchronizing a local oscillator
IPC: H03D13/00
Filed: 1969-10-28
Abstract: 1,271,307. Phase discriminators; automatic phase control. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 28 Oct., 1969 [31 Oct., 1968], No. 52764/69. Heading H3A. A sampling type phase discriminator comprising a semi-conductor switch 9, 10 which is periodically closed by a synchronizing signal 2 to connect a comparison signal 25 to a capacitor 13 is characterized in that the comparison signal is derived via a peak rectifier circuit 14 ... 21 including a potential divider 18, 19, 20 which provides a threshold in the signal 25 to maintain the switch 9, 10 open during the absence of synchronizing pulses 2. The minimum value of the waveform at 26 is clamped to a value dependent on the base potential of transistor 16, as determined by the potential divider 18, 19, 20, and a bias equal to the mean value of waveform 25 is developed across capacitor 15. The comparator is employed in a television scan synchronizing system and, as shown, the wave. form 25 is produced by integrating line output pulses in CR 21, 23. Alternatively it may be produced by differentiating a suitable parabolic waveform. The peak rectifier may employ a diode in place of transistor 16.

Abstract: 1350150 Data processing TELEFONAKTIEBOLAGET L M ERICSSON 16 Nov 1971 [20 Nov 1970] 53237/71 Heading G4A Each of a number of computers D1-D3 has its own clock CLO and counter CLR, and each counter, on reaching a predetermined count issues a signal E1-E3 to synchronize all the counters over a common line PIB and inputs F1-F3. A bistable circuit FF and delay circuit A co-operate to ensure that resetting of the counter CLR is not attempted while a clock pulse is stepping the counter. In general the fastest running computer will be forced to wait for the slower ones, and initiation of the synchronizing pulse will alternate between the computers in an irregular manner, but the faster computers, on average, will initiate the operation more frequently than the others.

Filed: 1966-11-29
Abstract: 1,133,036. Telegraphy. ATLANTIC RESEARCH CORP. 29 Nov., 1966 [31 March, 1966], No. 53294/66. Heading H4P. An arrangement for producing distorted telegraph signals comprises a logic circuit fed by the signal to be distorted both direct and via a delay, and by a signal representing the required degree of distortion. A telegraph combination to be distorted is set up manually on switches 26, Fig. 1, or a preset sequence of such combinations is derived from a store, and is passed in serial form to the logic circuit 10 both directly and via a ¢-bit delay, under the control of clock pulses which are also passed to the logic circuit. The clock pulses are derived from a counter 14, the output of which pulses the nine contacts of a selector switch 34 in sequence, first in one direction and then in the other. This switch selects the degree of distortion to be introduced in the code combinations, and so feeds to the logic circuit two pulses in each bit period, equi-spaced about the bit centre by an amount representing the distortion. Circuits are described for delaying or advancing the mark-space transitions, Fig. 5 (not shown), and the space-mark transitions, Fig. 4 (not shown), relative to the Stop-Start transition, which is never distorted. Delay or advance is selected manually. Alternatively, alternate code combinations in a sequence may have the transitions advanced and delayed respectively. In a further embodiment, Fig. 6 (not shown), all four forms of distortion are produced in turn automatically.

Title: Transistor amplifiers
IPC: H03F3/347
Filed: 1972-11-22
Abstract: 1389715 Transistor amplifiers WESTERN ELECTRIC CO Inc 22 Nov 1972 [24 Nov 1971] 53926/72 Heading H3T [Also in Division G3] A transistor amplifier comprises an input differential amplifier 102-107, an amplifier stage including a common base transistor 110, for coupling an output of the differential amplifier to an output stage 130-134 and current sources 112-115; 121, 127 for biasing the differential amplifier and the output terminal of transistor 110 respectively, the current sources being such that, in operation, their output currents are locked together in a constant ratio. In operation, an input signal at 100 is converted into two amplified complementary signals at 102-107, one of which is current amplified at 116, 117 and applied via a common base amplifier 110 to a Darlington amplifier 130-131 which produces further current amplification. The amplified signal is applied to an output stage 134 via a voltage level shifter 133. Feed-back elements 138-140 improve the high frequency performance of the amplifier. As the outputs of the negative current source 112-115 and the positive current source 121- 127 flow through the same control resistor 120, they are locked together and vary in the same direction to maintain the initial input offset set to a minimum by adjustable resistor 170. In the amplifier stage 116, 117, a fall in the base potential of 117 due to the input signal causes the common emitter potential to drop and as the base potential of 116 is substantially constant, a larger collector current is drawn by 116  from the common base stage 110. However, as in the embodiment of Fig. 3 (not shown), the stage 116, 117 may function as a differential amplifier by connecting the base of 116 to the output of the input Darlington pair 104, 105 instead of to a constant potential. The simple voltage level shifter 133 may be replaced by an arrangement (Fig. 2B, not shown) comprising a transistor 240 and current source elements 242, 243 wherein the sum of the base emitter voltage drop of transistor (240) and the substantially constant voltage drop across a collector base resistor (241) provides the required voltage level shift.

Abstract: 1328227 Non-woven fabrics CARL FREUDENBERG 26 Nov 1970 [1. Dec 1969] 56271/ 70 Headings D2A and D2B A perforated fleece of textile fibres is made by filtering an aqueous slurry of textile fibres containing a heat activatable bonding agent, through a screen and thereby collecting the fibres on the screen as a fleece containing unactivated bonding agent, making slits in the fleece, stretching the fleece transverse to the slits and activating the bonding agent by heating the fleece while it is stretched, thereby stabilising the fleece in the stretched state. The fibres are at least 4 m.m. long and may be of wool, cotton, regenerated viscose or synthetic polymeric material such as nylon or polyester. The bonding agent may be of the type that softens on heating and resolidifies on cooling, or that gels on heating, e.g. polyvinyl chloride, or that undergoes vulcanisation on heating. The bonding agent in the form of an aqueous coagulatable latex may be added to the slurry, coagulation being achieved by adding an acid or a salt, by changing the electric charge of the bonding agent particles or by heat, whereby the bonding agent is deposited onto the fibres. The screen is preferably a continuously moving band and the slurry is deposited near the bottom of an upwardly travelling steeply inclined part of the screen, and it is preferably subject to suction. The slits may be made by sprung knives or blades or by rolls carrying razor shaped segments, and the slits may be 2 to 8 m.m. long and are preferably arranged in parallel rows. The fleece may be incompletely dried on a roll drier before it is stretched and dried by heating to a temperature above the activation temperature of the bonding agent. The stretching opens the slits to form holes in the fleece. In an example, a mixture of viscose fibres and polyamide fibres are dispersed in water to form a slurry to which is consecutively added a coagulatable butadiene acrylonitrile latex sold under the trade name Butofan, and a coagulant called Polimin (Trade Mark).

Two or more systems 2, 3 of tubes 4, 4<SP>1</SP> may be carried on the underside of a non-rigid platform 1 held by adhesive and supplied with liquid through an inlet pipe 9, valve 8 and branch pipes 6, 10. Each system has a pressure gauge 7, 11 and the valve 8 can selectively isolate the systems one from the other and one or other or both from the inlet 9. When the volume of liquid in the systems is reduced below a certain value any load on the systems is transferred to packing members 5 between the adjacent runs of the tubes. The systems may be sandwiched between the platform 1 and another platform having lost motion relative thereto. Either or both platforms may be recessed to receive the tubes in the recesses and to form packing members therebetween. The non-rigid platform 1 is sufficiently rigid to prevent its lower surface contacting a support surface for the apparatus in the gaps between the runs but has sufficient flexibility to allow the partial loads supported by the two systems, when isolated from each other, to be ascertained from the two gauges so that the position of the centre of gravity can be estimated. The apparatus may be encorporated in a vehicle and used to find the effect of a load on a number of axles or several separate systems may be so disposed on a level concrete apron that each of the wheels of a vehicle can be made to rest on a different system.
