Abstract: 879,137. Stacking bricks. MASCHINENFABRIK BUCKAU R. WOLF A.G. Jan. 21, 1959 [Jan. 21, 1958], No. 2232/59. Class 94(1). [Also in Group XXX] Apparatus for stacking bricks on a trolley comprises a series of grippers, mounted on an endless conveyer, which remove bricks from a brick forming press and deposit them on the trolley or'stack. Bricks are moulded in groups of three by the press 1 and deposited on a rotary table 1d which conveys them beneath the gripper conveyer 3. Each gripper, operating by vacuum (see Group XXX), is depressed against spring means by a plunger 36 as it comes to rest over a group of bricks and rises with the group before the next conveyer movement. As a group of loaded grippers comes to rest over the trolley 9, the entire group is depressed by vertically reciprocating means 46, 47 to deposit a row of bricks as determined by photo-electric means 48, 48a. The trolley is supported on a wheeled carrier 7 which moves intermittently along rails 6 so that successive rows may be deposited to form a layer. The carrier 7 has a platform 8 supporting the trolley on rails 8a and this is lowered in steps to receive successive layers. The controls (not detailed) may be arranged to produce a stack tapering towards the top. The filled trolley is finally pushed off the carrier on to rails 17a aligned with the rails 8a.

Patent GB-740708-A (GB)
Title: Improvements in or relating to the oxo synthesis process
IPC: C07C27/22
Filed: 1953-01-27
Abstract: In a continuous oxo-synthesis at least a portion of the cobalt catalyst is added as an aqueous solution downstream of the injection-point of the olefine and gas feeds.  By operating in this way flooding of the reactor is prevented since water is more soluble in oxygenated product than in olefinic starting material and aqueous solutions of cobalt compounds obtained by the acid decobalting process, c.f. Specification 702,950, may be recycled to the reactor for use as synthesis catalyst.  Propionic, formic and preferably acetic acid may be used for decobalting.  An upward concurrent flow system is used.  Reactor product may be recycled as a cooling medium, c.f. Specification 647,363, to multiple points along the flow in the reactor and because of its content of oxygenated compounds aids the solution in the reactor liquids of the aqueous cobalt catalyst.  The addition of some of this solution to the bottom of the reactor is preferred as providing cobalt carbonyl catalyst.  Initially catalyst may be added as an oil-souble cobalt compound and the quantity thereof cut back as reaction progresses until all cobalt is added as an aqueous solution or a mixture of aqueous and oil-soluble catalysts may be used.  Water, optionally containing watersoluble cobalt compounds, e.g. the acetate or propionate, required for cooling and subsequent recycle may be added to the reactor but cooling is preferably effected by recycle of product as above indicated. Recycled cobalt salts obtained by acid decobalting may be injected at one or more points of the reactor.  A diagram of a suitable apparatus lay-out is provided and tables are given showing the solubility of aqueous catalyst in starting materials and reaction products.  Tables are also provided of experimental results showing the benefits obtained by carbonylating C7 olefines using the process of the invention the aqueous stream being added at a point at about 3/4 of the reactor height from the inlet of the reactants when compared with similar carbonylations in which cobalt oleate is used as catalyst with the addition of water as an extraneous stream or in which an aqueous stream of cobalt acetate is added at the bottom of the reactor. Specifications 689,146 and 690,977 also are referred to.

Title: Improvements in or relating to the mixed frequency and power-output regulation in electric power systems
IPC: H02J3/08
Filed: 1941-03-04
Abstract: 547,765. Automatic control systems for electric power systems. TRIGGS, W. W. (Akt.-Ges. Brown, Boveri, & Cie.). March 4, 1941, No. 2923. [Class 38 (iv)] Power output and distribution; frequency.- The power output and frequency of one or more generators or power stations in a network are jointly controlled by a programme controller P, one or more wattmeters W and a frequency error indicator F. Each instrument determines a voltage in proportion to its setting or indication ; the voltages from the wattmeters are opposed to the voltage from the programme controller in a series circuit including a reversible voltage from the frequency-error indicator, and the resultant voltage charges a condenser 1 which is intermittently discharged and produces by the selective operation of relays 17, 18 according to its polarity, correcting impulses. When controlling jointly a number of generators in parallel, load distribution may be maintained correct by injecting into the condenser charging circuit a voltage depending on the extent and sense of any relative loading error. When the condenser circuit voltages are A.C. back-to-back valves 4, 5 are included in the circuit. As shown in Fig. 2 valves 11, 12 in series with the respective relays are grid biased to cut off until the condenser 1 charging through a periodicity control resistance 3 determining the periodicity of arresting impulses overcomes the bias. A relay 17 or 18 then makes a correctional impulse at contacts R or A and short circuits the condenser 1, remaining operated so long as the charging current of a condenser 23 or 29 through a resistance 15 or 13 maintains the grid sufficiently positive. The sensitivity of the control depends upon the grid bias voltage which may be varied according to frequency error, power output value or rate of variation of condenser charging voltage and so forth. In a modification using D.C. voltages from the instruments P, W, F an additional sensitivity-determining voltage is added to the condenser circuit and the condenser discharges when a glow-discharge tube shunting it breaks down, the resulting circuit biasing a valve grid to cause energization of a relay giving the correcting impulse; this relay remains energized until a time-delayed contact thereon opens.
