Title: Improvements relating to a process for electrolytically filling the pores of a porous electrically conductive plaque
IPC: H01M4/29
Filed: 1969-01-30
Abstract: 1,262,342. Battery electrodes. YARDNEY INTERNATIONAL CORP. 30 Jan., 1969 [2 Feb., 1968], No. 5141/69. Heading H1B. [Also in Division C7] The pores of a porous conductive plaque, e.g. of Ni or Ni alloy are filled with nickel hydroxide by cathodically impregnating the plaque immersed with an anode, e.g. of Ni in an electrolyte bath comprising aqueous nickel nitrate solution, preferably containing between 700 and 1150 g./l. of Ni(NO 3 ) 2 .6H 2 O, and a wetting agent, e.g. " Carbowax " (Registered Trade Mark), having a pH of between 0 and 3, at at least 60 C., the initial current density being in excess of 1À5 A/sq. inch of the apparent area of the plaque, until the amount of nickel hydroxide in the pores is equivalent to a loading of at least 6 A hr./cu. inch. The voltage of the current supply is maintained constant relative to a Ag/AgCl reference electrode. The impregnated plaque may be soaked in a solution containing 5-45% KOH, cathodically polarized in the KOH solution, and/or anodically treated to convert the Ni(OH) 2  to a higher hydroxide. During impregnation, nitrate inside the pores is reduced to ammonia. The bath may further include Co(NO 3 ) 2 ; nitric acid may be added to maintain the pH. The plaque is suitable for use as an anode in a Ni-Cd cell or battery.

Title: Conveying system
IPC: B65G17/38
Filed: 1977-02-09
Abstract: The cable (3), guided over a drivewheel (1) which is driven to rotate, runs in a cable guide (4) designed as a pipe. In the latter, the cable (3) is guided without contact by means of sliding members (5) attached thereto. Fixed to the cable (3) is a connecting part (6) which extends outwards through an elongate slit in the cable guide pipe (4) and to which is fixed the load-carrying vehicle carrying the load which is to be conveyed. The cable (3) is designed to be electrically conductive, so that control commands can be transmitted to the cable drive (1). The cable guide pipe (4) is also designed as a guide rail for the load-carrying vehicle. Since the cable guide pipe (4) carries the weight of the load, the connecting part (6) is required to do no more than transmit the movement of the cable (3) to the load-carrying vehicle. The cable (3) and the sliding members (5) are thus not subjected to the weight of the load to be moved. <IMAGE>

Filed: 1965-02-10
Abstract: 1,089,862. Attenuators; amplifier circuits; gain control. COMMUNICATIONS PATENTS Ltd. Feb. 10, 1965, No. 5711/65. Headings H3T, H3U and H4R. A bridged-T attenuator device having an attenuation which may be varied whilst maintaining its characteristic impedance constant comprises rectifying elements 5, 7 having an impedance obeying the relationship log R = KV, where R is the A.C. resistance, V the direct current potential across the element and K is a constant. Such rectifying elements include silicon and germanium semi-conductor diodes. 1 and 2 are impedance elements in series with the signal path between input terminal 3 and output terminal 4. In order to maintain constant the characteristic impedance RO whilst varying the attenuation the impedance of the elements 1, 2 must equal RO and the relationship R1.R2 = RO<SP>2</SP> must be maintained, where R 1 is the impedance of element 7 and R2 the impedance of element 5. The attenuation is varied by applying a variable D.C. potential across the elements 5, 7, the respective potentials V1, V2 across these elements being varied inversely whilst keeping the sum V1 + V2 constant. In a practical embodiment (Fig. 3, not shown) the variable D.C. voltage across diodes (W1-W4) which are effectively connected in series is obtained from a transistor (VT1) having an electrode connected to the wiper of a potentiometer (RV23). The inverse variation of this voltage as between (W1, W2) and (W3, W4) (corresponding respectively to elements 5 and 7 of Fig. 1) is obtained from a transistor (VT2) having its control electrode connected to the wiper of a potentiometer (RV24).
