Title: Digital data receiver utilizing fine receiver timing and carrier phase recovery
IPC: H04L7/02
Filed: 1972-02-22
Abstract: 1373522 Digital transmission; synchronizing and distortion correction NORTH AMERICAN ROCKWELL CORP 22 Feb 1972 [18 March 1971] 8176/72 Heading H4P A timing recovery system for a receiver having a transversal equalizer with a plurality of taps comprises a first comparator determining the sign of the difference between signals at two taps and a second comparator determining the sign at two other taps, the outputs of the comparators at instants determined by first and second gating means controlling the frequency of a pulse train in accordance with the relative outputs of the comparators. The frequency may be adjusted by first and second add/delete circuits coupled thereto controlled by the comparators, the add/delete circuits being arranged never to add or delete pulses at the same time. Delay line 12 has a plurality of taps each connected through an adjustable attenuator, pairs of taps situated equidistantly astride a main tap being connected to respective comparison circuits 20, 21 which compares the sign difference of the most significant bits. The output, e.g. of 20 is gated through 22 to terminal B of switch 33 through add/delete circuit 26 and the frequency divider 28 to a pulse train sine wave converter 30 giving an output carrier. Gate 23 output passes similarly through a switch 31 to add/delete circuit 27 shich operates alternatively with 26 and both of which receive pulse trains from clock 25 at a frequency greater than the transition rate. A sectional frequency divider 29 has pairs of terminals A, B connected through switches 34, 35 to gates 22, 23 which in tandem with switches 31, 33 are switched through a series of programmed modes, 1 and 2 being regarded as coarse and less coarse initiation stages, and 3 as the fine running mode. The addition or deletion of a pulse by circuit 27 adjusts the phase of the carrier by a determined amount and in an alternative arrangement switch 31 is provided with an unconnected position intermediate between A, B. In an alternative arrangement Fig. 2 (not shown), which operates in similar manner, threshold detectors (62, 63), have outputs A when the input is positive causing adjustable frequency dividers (64, 65) to divide by n+1 hence delaying the output carrier phase, or an output B when the input is negative causing division by n. Each adjustable frequency divider may be a counter providing division by n or n + 1 before it generates an output pulse. In a modification, Fig. 3 (also not shown) the components (62-65) may be replaced by a phase modulator (71) controlled from switches 31, 33. Further modifications are envisaged in the specification.

Title: Improvements relating to vehicle direction indicators
IPC: B60Q1/36
Filed: 1946-03-16
Abstract: 609,568. Road-traffic signals on vehicles. LUCAS, Ltd., J., and TAYLOR, H. C. March 16, 1946, No. 8218. [Class 118 (ii)] A vehicle directionindicator of the pivotedarm type operated by an electro-magnet has an additional winding or a resistance brought into action by a contact device operable automatically when the indicator arm is moved into its service position, and one or each of the contacts of said contact device is carried by a thermallydeformable bi-metal strip. When the operating winding e of the operating magnet is energized, the core d is pulled down and a spring- loaded catch h mounted on a core extension-piece i engages a pin g on the indicator arm a. The continued descent of the core d therefore turns the arm a about its pivot f into the raised or service position, in which position a finger n on the base of the core d opens contacts k, mounted on spring members m, one or each of which is a bi-metal strip. Should the contacts k fail to open when the arm a is in the raised position, then the continued heavy operating current heats the bi-metal strip and should the arm a remain raised beyond a normal period, the bi-metal strip flexes and opens the contacts k to remove a short circuit from an additional winding j, or a resistance, in series with the operating winding e. Alternatively the additional winding j may be of much higher resistance than, and in parallel with, the operating winding e the contacts k then being arranged to break the circuit of the latter. In another embodiment (Figs. 3 and 4, not shown) the contacts k are mounted near the upper end of the core d and are opened by a shoulder of the core extensionpiece i. The bi-metal strip may be heated by passing the operating current through a surrounding coil instead of through the strip itself.

Title: Improvements in the recovery of organic acids from oxidation products of solid paraffin and like waxes
IPC: C07C51/487
Filed: 1929-03-14
Abstract: 333,904. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). March 14, 1929. Fatty acids, purifying &c.-A process for isolating fatt acids from the crude oxidation products obtained by the destructive oxidation of waxes, e.g. paraffin, montan, or beeswax, consists in treating the products at room or slightly elevated temperature with an alkali in amount sufficient to neutralize exactly the free acids contained therein, preferably drying the neutralized mass, and after removing unsaponifiable material and esters by extraction with a solvent, e.g. benzine, decomposing the resulting pure salts with a mineral acid. The alkali employed comprises the oxides, hydroxides, or carbonates of alkali or alkaline earth metals including magnesium, in aqueous suspension or in the anhydrous state. The pure salts, prior to decomposition, may be heated to remove traces of the solvent used for extraction. In one example, 50 parts of an oxidation product of paraffin wax, having an acid value of 221, a saponification value of 285, and a content of 13 per cent of unsaponifiable, material, are stirred at 60‹ C. with 10.5 parts of anhydrous sodium carbonate until the mass has become solid. The dried sodium salt is treated at 40‹ C. with benzine (boiling point 60‹ to 100 C.), the salt freed from the last trace of solvent by heating, and then decomposed by means of mineral acid. Specifications 315,813 and 324,538, [both in Class 2 (iii), Dyes &c.], are referred to.

Abstract: 1,123,211. Dynamic weighing. W. & T. AVERY Ltd. 28 Feb., 1966 [3 March, 1965], No. 9000/65. Heading G4H. A transducer 3 produces a signal in response to a moving wagon 1, the signal comprising a constant part corresponding to the staticweight of the wagon and a time-varying part caused by mechanical vibrations of the moving wagon. The specification shows that by multiplying the transducer output by a function f(t), integrating the product with respect to time over a period T and dividing the result by the integral of f(t) over the same period T, a quantity is obtained which more accurately represents the static-weight than if the mean value of the transducer output is taken over the period T. The function f(t) is single-valued, positive throughout T and is symmetrical about a maximum at T/2. The output from 3 is digitized at S, sampled by gates 13 and stored at 14. Clock generator 15 is started at the beginning of the weighing period T and supplies divider 19 which in turn feeds counter 16. Each time counter 16 overflows, a fresh sample is introduced by gates 13 and counter 18 is advanced to vary the division ratio of the divider 19 in accordance with f(t). Serializer 7 produces a number of pulses corresponding to the product referred to above. Divider 8 divides by the integral of f(t).
