Abstract: 969,157. Graphical displays for work programming. MANAGEMENT STUDIES Inc. Feb. 1,1963 [Feb. 12,1962], No. 4269/63. Headings G4B and G5C.  A programming device 20 comprises a board 22 having a series of parallel paths, along which gauges 30 aremovably arranged in series and parallel networks,and junction members 36 crossing the paths at right angles. In use, gauges 30a, 3Ob (Fig1) represent consecutive activities, say specifying and designing an electronic device, which must be completed before another set of activities, say drafting, circuit designing component designing and mechanical designing, represented by gauges 30c-30f and performed concurrently, can begin Of those, the activities represented by gauges 30c-30e must be completed before other activities, 30h, 30j, can begin. Finally the-device must be completed before testing, represented by a gauge 30g, can begin. Some paths will have gaps, representing slack time, but a "critical path" representing the duration of the whole programme will be continuous from gauge 30a to 30g (Fig. 6, not shown). Gauges 30 (Fig. 2) may be rectangular blocks on wheels running in channels 24 of the board 22. The. gauges may be available in various lengths, representing durations of the corresponding activities, and carry space 52 for job details. The gauges may have end contacts 63 and bulbs 65, for indicating the "critical path", or resistors representing job duration &c. for summation. Junction members or fences 36 may be thin rods on large discs (Fig. 3, not shown) and the rods may fit grooves in the gauges. The board 22 may slope, so that gauges and fences tend to slide down, and have a scale 50 and a movable straightedge 51. Fig. 7 shows another form of fence 56, of sheet metal, and a gauge 57 having a scale marked on it. Figs. 10, 11 (not shown) illustrate a U shaped gauge fitting over ribs 26 (Fig. 1) Fig. 12 shows a gauge 76 whose length is adjusted by a key 112, or an electric motor, causing a tape 116 to be unwound as collars 78, 80 are separated. The gauge hangs down between rafters 74 in an open board, rods 120,122 threading through the collars and replacing fences (Fig. 14, not shown). Boards can be joined together for planning big jobs, changes in the programme being recorded by photographing &c., and estimated times being replaced by actual times as a job progresses.

Title: Apparatus for monitoring the state of charge of a storage  bettery
IPC: G01R31/36
Filed: 1975-02-03
Abstract: 1473633 Monitoring battery charge VARTA BATTERIE AG 3 Feb 1975 [4 Feb 1974] 4565/75 Heading G1U The state of charge of a storage battery e.g. for vehicle traction is monitored by an ampere-hour meter connected to a measuring resistance carrying the cell current, the input to a non-linear network being connected in parallel with the resistance and its output being connected to the meter in series with the resistance. The network provides compensation for the increased effect of high discharge currents on the consumed capacity Fig. 3 (not shwon). The network comprises an input amplifier (IC3), Fig. 2 (not shown) feeding a network of diodes and resistors to provide an approximation to the desired characteristic. The ampere-hour meter comprises an integrator (Fig. 1), followed by a pulse counter Fig. 4 (not shown). Integration is effected by amplifier ICI and capacitor C1. Discharge currents J provide a positive output from IC1 which passes via diode D1 to a Schmitt trigger T1, T2 which produces an output pulse Z for every increment of charge determined by the trigger threshold. A second trigger output is fed back to fire thyristor Th 1 to discharge the capacitor Cl, thereby resetting the integrator. A charging current produces a negative output from IC1, which is inverted IC2 before being fed to the Schmitt trigger. Pulses representing charge and discharge currents are available at terminals X, Y respectively for supplying to an up-down counter. The pulse counter Fig. 4 (not shown) comprises an input pulse shaper followed by a divide-by-ten stage. This stage provides the input to a counter whose outputs are decoded to drive flashing lamps which indicate remaining capacity from 10-100% in 10% steps. The counter output representing 10% is detected and used to block further inputs, thus holding the minimum indication. The counter is manually resettable.

Title: Improvements in or relating to the preparation of aqueous dispersions of rubber or the like
IPC: C08J3/03
Filed: 1944-03-18
Abstract: 579,352. Rubber dispersions. B. B. CHEMICAL CO., Ltd., PUDDEFOOT, L. E., and GEORGE, K. J. March 18, 1944, No. 5062. [Class 1 (i)] Aqueous dispersions of reclaim rubber having improved adhesive and film forming properties are produced by dispersing water in the rubber with the aid of colloidal aluminium hydroxide or sodium silicate or both, diluting with more water to reverse the phases, and adding a stabiizer. e.g., casein, soap, glue gelatine, albumen sulphated oils, or sulphated fatty alcohols. Preferably 2-5 per cent. of dispersing agent and 1-3 per cent. of stabilizer, by weight of reclaim rubber, are used. All the dispersing agent is preferably milled into the rubber before adding any substantial amount of water. A minor proportion of stabilizer, e.g., 0.5-1.2 per cent. of soap, by weight of reclaim, is preferably added before dilution, but preferably the major portion of the dispersing agent is added before the major portion of the stabilizer. Softeners, e.g., cumar resin, mineral rubber, or preferably up to 25 per cent. Niger Flake may be used, but normal mixing without softeners is preferred since detrimental resin soaps may be formed between the softener and any alkali added to neutralize its acidity. The dilution water is preferably alkaline, e.g., 1 per cent. ammonia or ¢ per cent. caustic soda solution. Examples are given using tyre carcass &c. rubber, stearic acid being preferably added where the carbon content is high to prevent adsorption of the dispersing agent. The Provisional Specification describes the use broadly of colloidal inorganic dispersing agents which are preferably basic and the application of the process to all kinds of rubber.
