Abstract: 1,231,717. Automatic exchange systems. INTERNATIONAL STANDARD ELECTRIC CORP. 13 June, 1969 [18 June, 1968], No. 30064/69. Heading H4K. In a system including a number of remote satellites individually connected by data links and speech channels to a central exchange, the satellites are connected to each other in pairs whereby in the event of a failure in a direct connection from one of the satellites to the exchange data for this satellite can be routed thereto via its partner. If the total number of satellites is odd, the unpaired one may be connected by a tie to any one of the paired ones. In the satellite shown, the data NS and speech TC1 . . . TCn channels are connected over a cable C to a central exchange P while an emergency data cable HS which may include speech channels extends to the satellite's partner. If the latter's direct cable should break, the central exchange signifies this fact to the shown satellite's control circuit TU over the data channel NS. Thereupon bi-stable NK is set so as to bring up relay Rb and thereby connect at least one of the speech channels TC1 &c. to the emergency data cable HS. The central exchange transmits low level carrier over TC1 and HS to the faulty satellite whereat a carrier detector CD responds to set bi-stable M and so brings up relay Ra. The faulty satellite's control circuit TU is thereby connected via. the emergency cable and channel TC1 to the central exchange whereafter local calls can be set up by this satellite irrespective of the number of speech channels TC that have been made available by its unfaulted partner. When the fault is cleared the central exchange signals over NS to the unfaulted satellite whereupon Rb is released after a delay and over TC1 to the faulty satellite whereupon Ra is released. It should be noted that only one of relays Ra, Rb can be operative together in any one satellite. An unpartnered satellite may be connected up by a net shown second Rb relay which is controlled by bi-stable Nx. This second satellite is not provided with an Rb relay.

Abstract: 1,251,241. Cigarette mouthpieces. BROWN & WILLIAMSON TOBACCO CORP. 9 Jan., 1969 [12 Jan., 1968], No. 1469/69. Heading A2C. Composite cigarette mouthpiece rods that are divisible into mouthpieces having a particulate component in line with other components are manufactured by feeding the other components end-wise in a line with predetermined spacings between these components, partially enclosing these components in a wrapper such that there is an opening along the top of the wrapped components, introducing the particulate material via the top into the space between the other components, filling said space, and sealing a second wrapper about the components, first wrapper and open top, thereby forming a continuous rod. The first wrapper may be porous or perforated so that suction may be applied to the space between the other components to expedite the rate of filling of the space. The manufacture may be carried out in an assembly of the type shown in Fig. 1, wherein mouth piece components in the form of plug lengths are fed from hoppers 14 on to a suction conveyor 18. These components are then fed on to, and predeterminately spaced on, a first wrapper 24 which is driven by a wrapper conveyor 28. The first wrapper is of a width slightly less than the circumference of the components such that when the wrapper and components are fed to the first wrapper folder 36, a partially wrapped rod having an opening along the top, is formed. At the filling station 44, particulate material is fed into the spaces between the components via the top opening. The partially wrapped rod is further fed to a second wrapper folder 64 wherein the second wrapper 38 is wrapped around the rod thereby to completely embrace the exterior surfaces of the first wrapper and the top opening. The wrapper material may be of thermoplastic and may be sealed by heaters 42 and 66, for the first and second wrapper respectively. The completely wrapped rod is then passed to a cut-off device 68 which operates to cut the rod into selected lengths.

Abstract: 1,256,676. Measuring battery charge state. BROWN, BOVERI & CIE AG. July 10, 1970 [July 26, 1969], No. 33696/70. Heading G1U. The state of charge of a battery 3 is determined by measuring its internal impedance (which rises as the battery discharges), this being effected by passing a constant alternating current through the battery and measuring the resulting voltage drop across the battery. The actual value of the alternating current passing through the battery from a generator 1, amplifier 2 and coupling transformer 4 and capacitor 5, is represented by the potential across a resistor 11 in the battery circuit. This potential, after filtering and amplifying 13, 14, 15, 16, is compared with a preset potential in a comparator amplifier 17 in order to control the generator amplifier 2 and thereby maintain the current constant. The resulting voltage across the battery may, after filtering and amplifying, be displayed on a meter 9, or used to control indicator lamps 10, that corresponding to the lowest state of charge being arranged to flash when energized.

Abstract: 1328495 Balance taring system L OERTLING Ltd 3 Dec 1970 [3 Sept 1969] 43705/69 Heading G1W In a precision balance having a fine balance system, and a weight-loading system including control means operable by a manual linkage for loading weights on to the balance in increments to achieve an approximate balance within the range of the fine balance system, an indicator is coupled to the control means to indicate the loading weights applied to the balance and is operable by the manual linkage independently of the control means so that it may be reset to zero without disturbing the loading weights, thus increasing the range of measurable tare weight. The control means comprises two concentric shafts 24, 30, the outer shaft 24 bearing cams 22 such that its rotation selectively and progressively loads taring weights (21) on to the balance, the load being indicated by the indicator drum 32 mounted on the inner shaft 30, since when outer knob 25 is turned the shafts rotate together, being coupled frictionally, shaft 24 being indexed on the balance frame by click-stop cam 26 and a coacting spring (27). After the loading weights (21) have been adjusted and the fine balance system zeroed to allow for the tare weight of a container, inner control knob 31 is rotated and since click-stop arrangement 35, 36 is weaker than the cam 26 and spring (27) the inner shaft only rotates to zero the indicator but leaves the weight undisturbed. Microswitch 37, operated by rod 38 and detent 39, senses relative rotation of cam 26 and drum 32 to illuminate an indicator lamp when taring is taking place. The fine balance system and the weight-loading system having both been zeroed, material placed in the container can be directly weighed in the conventional manner. In an alternative embodiment mentioned a digital weight-loading system comprising four or five indicator drums may be used.
