Title: Improvements in or relating to endless belt conveyors
IPC: B65G39/14
Filed: 1959-12-21
Abstract: 937,132. Endless belt conveyers. GOODMAN MANUFACTURING CO. Dec. 21, 1959 [Dec. 24, 1958], No. 43343/59. Class 78 (1).  To maintain a training effect on the belt of an endless belt conveyer comprising troughing idler roller assemblies suspended between a pair of cables extending longitudinally of the conveyer, each end of each assembly is connected to the respective cable by means of a connector which holds the end of the assembly against angular movement in a plane parallel to the adjacent portion of the cable and maintains the respective wing roller of the assembly with its outer end displaced forwardly in the direction of belt travel.

Title: Water heaters
IPC: F24H1/10
Filed: 1972-09-19
Abstract: 1460143 Electrode boiler D G TATE and R P WOODS 17 Dec 1973 [19 Sept 1972] 43344/72 Heading H5H [Also in Division F4] A water heater comprises a container 1 e.g. a pipe, a neutral plate electrode 2 within the container, a live plate electrode 3 located within an aperture in the neutral electrode and spaced therefrom by a uniform gap 4, and an insulating layer 7 e.g. of P.T.FE between the container wall and the electrodes. The neutral plate electrode 2 is cylindrical and the live electrode 3 is arcuate, having the same curvature as the neutral electrode and being centred on the same axis. A control electrode 12 may be provided to vary the heating effect. When the earthed electrode 12 is adjacent the electrode gap 4 it increases the number of current paths between electrodes 2, 3 and thus the heating effect. When water is first passed through a pipe 1, the control electrode 12 is adjacent gap 4 and rapid heating ensues. As the water temperature rises a thermal bellows 14 expands raising the electrode 12 and thus reducing the heating effect. A flow sensitive device may actuate the heater for a timed period. The heater may be formed as a waste trap sterilizer unit, one arm of the U trap containing the heating electrodes and the other arm containing a flow sensitive switch which is arranged to actuate a magnetic reed or microswitch controlling the heater. Fig. 4, shows a printed circuit form of electrodes, the outer neutral one 25 containing four live electrodes 22 in separate apertures. The live and neutral electrodes have interdigitated extensions 23, 24 as shown. The electrodes may be formed on rigid or insulating boards, which may be flat or curved. The heater may be controlled electronically by a sensing electrode which produces a control pulse when water flows. The pulse is sensed by an operational amplifier (Fig. 5A, not shown), which passes the signal to a timer, or by an electronic timer direct (Fig. 5B, not shown). The timers connect the heater electrodes to a supply by means of a triac and a reed relay for a time change the state of the output from I3 and the circuit output 32 switches to its other state to turn on transistor N2 and turn off transistor P2 thus further reducing the impedance of path 1, 16 and increasing that of 1, 14. When E approaches +V, transistor P1 turns off. As E falls the reverse action takes place until I3 again switches, this time at a point where V1 has risen + V/2. The two switching points are thus determined by the relative impedances of the transistors in the two paths 1, 14 and 1, 16 and not by their absolute magnitudes. In a modification, Fig. 3 (not shown), the transistors P3, N3 are replaced by two transistors (P3a, N3a) connected in parallel between the junction of P1, N1 and the junction of P2, N2. This alternative form is used in a NAND circuit arrangement Fig. 5 (not shown).

Title: Fully automatic battery charger
IPC: H02J7/00
Filed: 1970-09-16
Abstract: 1319343 Battery charging systems GLOBEUNION Inc 16 Sept 1970 [6 April 1970] 44156/70 Heading H2H Charging apparatus for a battery is arranged to charge a battery in a predetermined manner according to the state of charge of the battery or the battery terminal voltage so as to maintain the battery in a fully charged state. A battery 14 is charged from an A.C. source 24 by way of a rectifier bridge 20 and a series connected transistor 34 which functions as a variable resistor to control the charging current. Connected to the terminals 16, 18 of a deeply discharged battery a network of resistors 38, 46, 47 and diodes 48, 50 provide a forward bias for the transistor 34 so that it is fully turned on to provide a steady charging current for the battery 14, which current is limited by the resistor 46. As charging proceeds the battery voltage rises until a prescribed minimum voltage is reached at which Zener diodes 62, 64 break down whereupon the potential on the base of a transistor 52 turns this transistor on. This reduces the positive bias on the base of transistor 34 such that its impedance increases to reduce the charging current. As the battery voltage further increases, transistor 52 becomes more and more conductive and transistor 34 less and less so, until at a prescribed intermediate battery voltage the transistor 34 cuts off. Thereafter an unregulated current to continue charging the battery flows by way of resistor 74, conductor 100 and diode 76. When the battery has become fully charged the unregulated charging current is terminated by a device including a bi-stable multivibrator 84 and a switching transistor 82. Transistor 82 is normally turned off and the transistor 96 of the multivibrator conductive. When the battery is fully charged the potential at point 90 becomes such as to switch the multivibrator whereupon transistor 82 turns on thus by-passing the unregulated charging current to earth 31. Lamp 86 indicates a fully charged battery and lamp 40 indicates the battery being charged by way of the transistor 34. When transistor 82 turns on to switch the unregulated charging current the circuit components are such that transistor 34 turns on to provide a very small trickle charging current. Should the battery voltage fall below the value at which the Zener diodes 62, 64 break down transistor 52 will turn off thus causing transistor 34 to become fully conductive so as to supply charging current to the battery of a "trickle" charge value. At the same time the cutting off of the transistor 52 applies bias to the base of transistor 96 in the multivibrator 84 by way of a resistor 122 and a Zener 120 whereupon the multivibrator is reset. Resistor 80 then becomes non-conductive to remove the by-pass to earth to permit the flow of unregulated charging current by the circuit 74, 100, 76.
