Title: Fire-extinguishing composition
IPC: A62D1/06
Filed: 1927-04-01
Abstract: 269,879. Amdyco Corporation, (Assignees of Dunlap, F. L., and Ewer, N. T.). April 21, 1926, [Convention date]. Chemicals.-A dry composition adapted to form foam on addition to water and containing, for example, aluminium sulphate, sodium bicarbonate and a stabilizer such as extract of liquorice or oak bark is protected from deterioration during storage by the addition of a dry, inert substance such as clay, talc, starch, or flour. The aluminium sulphate preferably has its water of crystallization content reduced to seven molecules and all the ingredients are reduced to a sufficient fineness to pass a forty mesh sieve. In this way the reduced solubility due to loss of water of crystallization and addition of inert material is balanced by increased fineness of particles. An exemplary composition comprises thirty-five parts by weight of aluminium sulphate, thirty-nine parts of sodium bicarbonate, six parts of stabilizer, and thirty parts of china clay. Specification 250,924 is referred to.

Title: Improvements in or relating to baling or bundling press
IPC: B30B9/30
Filed: 1923-04-05
Abstract: 220,018. Towler, F. H., and Towler, J. M. April 5, 1923. Press w o r k i n g valves.- In a baling or bundling-press in which compression is effected between a pair of opposed hydraulic rams. one of which acts as a buffer to the other, and in which a preliminary compression may be effected by a filling ram, the operation of the rams is controlled by valves such as are shown in Figs 10 and 11. At the beginning of a cycle of operations the valve 31, Fig. 10, is on its rear seat 31<a> and the valve 35, Fig. 11, controlling the buffer ram, is closed. Pressure fluid then passes through a non-return valve 34 to a pipe supplying the cylinder of the filling-ram, which moves inwards and throws over a lever at the completion of its stroke, and moves the valve 31 on to the other seat 31b. Fluid then passes through the seat 31<a> and outlet 28 to the compressing ram, which makes its stroke. Meanwhile, the valves 35, 45, 46 are closed and hold the buffer ram stationary. The valve 35 is then opened manually by a handle 40, or automatically by tappets 41 on the compressing ram and fluid escapes through the valve 45 to allow the compressing and buffer rams to move toegther. On the completion of this movement, the valve 31 is thrown again on to its seat 3<@a> and the fluid from the compression cylinder escapes through valve 33, seat 31<b>, and valves 34, 35, to allow the parts to regain their initial positions.

A lighting installation, in which the light intensity may be progressively varied from its normal full value to '' black-out " and vice versa, comprises hot- or cold-cathode discharge lamps 1 and incandescent lamps 6 in association with separate dimmers, the arrangement permitting dimming of the discharge lamps from full brightness to the point at which the discharge becomes unstable and then further reduction of illumination by operation of the dimmer controlling the incandescent lamps, the full brightness of which roughly corresponds with the minimum brightness of the discharge lamps. The two types of lamps preferably emit light of the same colour, being assisted, if necessary, by filters, and are also preferably arranged to illuminate the same area. For this purpose each lighting unit may comprise a tungsten filament lamp having a " daylight " blue envelope surrounded by a spiral shaped discharge lamp emitting a " daylight " discharge, the whole being in a frosted glass diffusing cover. Lamps of one type may be extinguished whilst those of the other type are in operation, this being effected automatically in the system shown, which also incorporates ganged control of the dimmers R1, R2 for the discharge and incandescent lamps, respectively. The discharge lamps are supplied from A.C. lines 17 over contactor 13, transformers 4 and saturable reactors 2, the D.C. control windings 12 of which are energized over dimmer potentiometer R1 from a source 3. The incandescent lamps are energized over " black-out " switch B, dimmer potentiometer R2 and switch S2 from the A.C. lines 17. The common moving arm 5 of the two dimmers is actuated by a reversible motor 7 and, in addition to controlling the output voltages of the potentiometers, is adapted to operate the " black-out " switch B, the control switch S 1 for closing the discharge lamp contactor 13 when the incandescent lamps have reached full brightness, and the switch S2 which opens the incandescent lamp circuit when the discharge lamps are approaching full brilliance. At full brilliance position of arm 5 a limit switch L operates to stop the motor.

The leg sinews of poultry are drawn out from the middle part of the leg by pulling away the lowest part along with the sinews in the middle part. The lowest part of the leg is placed in a slot 9.between gripping jaws 4, and the middle part of the leg lies between pivoted cutting edges 32 which are clear of the sinews. The jaws 4 are then pulled away from the edges 32 which thereby pivot to close on the middle leg to sever the skin and bite into the bones to hold the middle leg while the jaws 4 pull away the lowest part of the leg carrying away with it the sinews of the middle part. The jaws 4 coupled to long pivoted arms are moved away by toggle links 16, 17, Fig. 1 (not shown), operated by a treadle 25. The pivoting and cutting-in action of the edges 32 is limited by adjustable stops 35. The edges 32 are initially urged towards each other by springs 33 to close on the middle leg when placed initially between the edges 32. An adjustable stop 34 limits the advance of the jaws 4 towards the edges 32 when the treadle 25 is released.
