Abstract: 1278935 Winches SAMUEL LEWIS (WINCHES) Ltd 11 July 1969 [17 July 1968] 33932/68 Heading B8B A collapsible hauling apparatus (Fig. 2) comprises a housing 1 containing a winch for a hauling cable A, a tension gripping member 2A adjustably attached to the housing and a cable guiding member 9 pivotable about the housing and angularly lockable in one of a plurality of positions relative to the member 2A such that a pulley 25 on the member 9 exerts a downward force on the cable when the apparatus is erected and operating. The tension gripping member 2A is mounted on an integral extension 3 of the housing 1, the member 9 being pivotal at 6 to the housing 1 and being spaced from the extension 3 by a support strut 19 which may be selectively pinned to one of three apertures 26 in the member 9. The cable A passes between two pulleys 24, 25 mounted in a pulley housing 21 pivoted to the end of the member 9. An extensible steadying arm 13 is pivoted at 14 to the housing 1 and for operation is selectably positioned relative to the extension 3. In the inoperative condition, the arm 13 and the guiding member 9 are pivoted towards the extension 3 and locked in positions parallel therewith. The winch (Fig. 4) in the housing 1 comprises a cable drum 29 driven through ratchet wheels 30 thereon and a hauling pawl 36 actuated by a handle 18, the wheels 30 being locked by a pawl 39 when not driven by the pawl 36, and both pawls being spring biased into engagement with the ratchet wheels 30. Pay out of cable A under tension is facilitated by a time delay member 33 including a spring piston and cylinder arrangement coupled by a rod 46 to a lever 41 pivoted at 30a to the same axle as the hand lever 18. When the member 33 is spring gripped to a projection 52 on the handle 18, projections 44, 45 on the free end of the lever 41 are sequentially engageable with the pawls 36, 39 to lift the same clear of the ratchet teeth once the force from the teeth, on the appropriate pawl, has been relieved. The pay out is controlled by clockwise movement of the handle 18 during which the pawl 36 is in engagement with the ratchet wheels 30 and the pawl 39 is held out of engagement therewith by the projection 45, the pawl 39 engaging the wheel 30 and the pawl 36 being held out of engagement therewith by the projection 44 during anti-clockwise movement of the handle 18. The member 33 may be pivoted into an inoperative position in which it spring grips a part 55 of the housing 1 and the pawl 36 may be rendered inoperative by hooking an extension thereof on to the housing 1 at 58.

Title: Learning machine
IPC: G06K9/62
Filed: 1970-07-13
Abstract: 1317745 Learning machines MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd 13 July 1970 [14 July 1969 (2)] 33958/70 Heading G4R A learning machine uses a plurality of items of standard pattern information from a memory in turn for training, weights being adjusted until a thresholded sum equals a desired value, when the next standard pattern is taken from the memory for use in the training. Prior to training, standard patterns are passed via an input buffer to a shift register memory which also receives the corresponding desired outputs. In training, each pattern from the memory in turn is passed into the input buffer, a weighted sum of the bits which are equal to 1 being thresholded at one of two thresholds depending on the desired output. If the results of this (the actual output) is equal to the desired output, the next pattern is obtained from the memory, but otherwise the weights which contributed are all incremented or all decremented as appropriate. During recognition, an input pattern in the input buffer forms a weighted sum which is thresholded at a constant level to give the output.

Title: Process for removing iron from solutions of chromium salts
IPC: C01G49/00
Filed: 1932-12-05
Abstract: Iron, reduced when necessary to the ferrous state, is removed from acid solutions of chromium salts by treatment at a raised temperature with a small excess of b -naphthalene-sulphonic acid or a soluble salt thereof, and separation of the precipitate from the liquid after cooling.  The insoluble ferrous salt may be then treated with alkali carbonate for the production of the alkali salt of b -naphthalene-sulphonic acid for re-use in the process. In an example, ferrochrome is added to aqueous sulphuric acid, the mixture heated to 110 DEG  C., diluted, and left to crystallize ferrous sulphate. After separation thereof, there is added a solution of b -naphthalene-sulphonic acid.  The ferrous salt is precipitated on cooling, the remaining iron-free chromium solution being suitable for tanning.  Reference is made to the dissolution of an iron-containing chromium slime in sulphuric acid, reduction of the iron to the ferrous state, and its removal as above.

Title: Method and a circuit for measuring a dc signal having a very high noise level
IPC: H04B17/40
Filed: 1974-08-06
Abstract: 1473726 Measuring D C voltage COMPAGNIE INDUSTRIELLE DES TELECOMMUNICATIONS CIT-ALCATEL 6 Aug 1974 [16 Aug 1973] 34628/74 Heading G1U In measuring a D.C. signal accompanied by noise, an integrator comprising a capacitive feedback amplifier is used, where the amplifier has a finite gain, A. The input signal S + N is integrated for a predetermined time t, during which the voltage or capacitor 3 and storage capacitor 4 rises exponentially towards a final value V o  = A.S, reaching at time t, a value V 1  = V o  (1-e<SP>-t</SP>1/#)+E, where T is the integrator time constant and E is the noise level, A.R.C. At this time, switches 5, 9, 10 are reversed, applying to the integrating capacitor a voltage KV 1  via the multiplier 6, 7, 8. By arranging the constant K to be 1-e<SP>-t</SP>1/#, a new signal V a  is produced which differs from the value V o  by KE. After a short time, switches 9, 10 are switched back and the integration proceeds. The portion KE now decreases exponentially and the final value V o  is approached. After a predetermined time t 2 , the signal level (without noise) has approached within an acceptable range e.g.  1% of its final value, and this is then measured 16, from which the value S can be determined. By choosing K = 2, the total measuring time t 1  + t 2  is reduced to minimum, being about 1.8T, as compared to about 5.3T for a simple RC integrator. The system is said to be used for measuring low-level test signals received from repeaters in submarine cable systems.

Title: Improvements in or relating to gas purity detectors
Inventor: EASTON VIVIAN
IPC: G01N9/26
Filed: 1954-11-30
Abstract: 782,517. Determining specific gravity. GENERAL ELECTRIC CO., Ltd. Nov. 21, 1955 [Nov. 30, 1954], No. 34668/54. Class 97(3) The purity of a gas is determined by measuring its density by observing with a manometric device the pressure difference between the two sides of a fan rotating in the gas, the manometer being connected to a sealed - chamber in which gas is trapped above the liquid so that more liquid is forced into it as the absolute pressure of the gas under investigation increases. As shown, the pressure and suction sides of the fan are connected at 9, 10 respectively to compartments 5, 4 in a container 1 divided by partitions 2, 3 having apertures 7, 8 at the bottom, the latter aperture communicating with a closed chamber 6. The container is filled with liquid at atmospheric pressure through the aperture 14 which is then closed. When the fan is operating the liquid falls in the compartment 5 and rises in the compartment 4 until a float 11 is lifted to operate a device 13 which gives a warning when a predetermined proportion of impurity is present. An excessive lift of the float lifts a needle valve 17 to close the aperture 10 and prevent escape of liquid from the compartment 4. The difference in levels, for a particular proportion of impurity increases with the absolute pressure but this is compensated. as regards the device 13, by a fall in both levels produced by the flow of liquid into the compartment 6. The sensitivity characteristics may be modified by the choice of the functions which determine the variation of cross sections of the compartments with height.
