Title: Improvements in and relating to foundry moulding and casting apparatus
IPC: B22D29/02
Filed: 1949-07-27
Abstract: 665,034. Foundry-plant. FORD MOTOR CO., Ltd., and LEEK, J. W. May 25, 1950 July 27, 1949], No. 19778/49. Class 83 (i). [Also in Group XXX] Foundry moulding and casting plant in which flasks are carried past the various operation stations on a conveyer and in which each flask is controlled at the discharge station by an arrangement which lifts or drags it from the conveyer and shakes out the sand and castings, is characterized in that a plurality of lifting and dropping arrangements are carried in spaced relation on a circulating conveyer. Flasks 1 are supported on plates 2, Fig. 1, resting on platforms 3a carried at the lower ends of bars 8 depending from a conveyer. One side of each plate 2 is secured to a rod or chain 3 connected at its upper end to a lever 6, the other end of which carries a roller 9 co-operating with a fixed cam surface 10. A lifting-hook 4 mounted on the rod or chain 3 engages a projection 5 on the flask. When the cam 10 depresses the roller 9, the hook 4 lifts the flask off the plate 2 which is tilted and also jolted by notches in the cam surface so that the sand and castings fall from the flask and are directed on to a vibrating- conveyer through which the sand passes to a receptacle 12 and from which the castings are conveyed to a rotary hopper 14 and thence discharged into conveyer baskets 15, the movements of the hopper and baskets being synchronized. In a modification, Fig. 4, the upper part of the flask is lifted by a separate chain 19, while the lower part is pivotally mounted on the hook 4 so that it tilts by gravity to discharge its contents. In another modification, Figs. 5 and 9, the conveyer carrying the platforms 3a is offset to provide room for a vibrating table 19 between it and a subsidiary conveyer 20. As a flask on a platform 3a arrives opposite one end of the conveyer 20, a projection 5 on the flask is engaged by an arm 24 carried at the lower end of a bar 21 depending from the subsidiary conveyer. The bar 21 is tilted by cam means and the arm 24 is operated by a fluidpressure cylinder, the control valves of which are cam-actuated so that the flask is lifted from its platform 3a and dragged over the table 19, through which the sand is discharged. At the end of the table the casting falls down a shoot 31 and the flask is then deposited on the back platform 3a at the other end of the subsidiary conveyer.

Title: Electrical signal generating systems
Inventor: YATES-FISH NORMAN LAURENCE
IPC: H03K5/06
Filed: 1953-07-17
Abstract: 728,569. Electric selective signalling. MINISTER OF SUPPLY. July 17, 1953, No. 19891/53. Addition to 706,687. Class 40 (1). [Also in Groups XL (b) and XL (c)] A series of 2-state signals (+, 0) are individually converted into a series of 3-state signals (+, -, 0) by means for producing an alternate + and - for consecutive + signals of the 2-state code. In one embodiment (Fig. 1) a gate G, fed with the 2-state signals S (Fig. 3a) and clock pulses CP (Fig. 3b), has its output (Fig. 3c) applied to a trigger T which changes its state with each + signal (Fig. 3d). The trigger T is connected to the control grid of a valve V1  which only conducts at the positive grid signal, producing a drop in voltage across anode resistor R which is transmitted through a delay line DL1, and, after reflection by the shortcircuited end, returns with reversed polarity to annul the drop in voltage. Resistor R is equal to the characteristic resistance of the delay line. Thus the output from terminal t1 is a succession of pulses of opposite polarity (Fig. 3e), the duration of the pulses being determined by the delay time of delay line DL1. The gate G may be dispensed with. In another embodiment (Fig. 2), the state of trigger T is changed by successive pulses of the 2-state signals S (Fig. 3a) to cause valve V2 to be conducting or cut-off alternatively. The changes in anode voltage cause a current flow through open-circuited delay line DL2 and resistor R2 which is cancelled after a delay equal to twice that of the delay line. The output from a terminal t2 is thus that shown in Fig. 3e. The combined series resistance of resistors R1, R2 is equal to the characteristic resistance of delay line DL2.

Title: Method of manufacturing colours of iron, or crystallized sulphate of iron or other soluble salts of iron from pyrites cinders
IPC: C01G49/06
Filed: 1933-06-15
Abstract: Residues from the combustion of pyrites are at their outlet from the ovens collected in a state of incandescence in a chamber containing no oxygen, so that they are quickly cooled without oxidation to ferric oxide.  After optional purification in an electromagnetic separator, the cinders may be pulverized and employed as a black pigment, or without pulverization, treated with 50--52 B<\>ae sulphuric acid to produce a paste of iron sulphates.  This paste may be crystallized, or calcined to produce a "red" pigment. Alternatively, it may be partially calcined and extracted with water. The washing liquors, or a solution of the uncalcined paste, may be treated with soda, potash or lime (oxide or carbonate) to produce various "iron yellows," e.g. iron hydrate, or "French yellow" (a mixture of iron hydrate and calcium sulphate).  The different pigments obtained may be mixed in various proportions.  Other crystallized iron salts may be obtained similarly to the sulphate.

Abstract: 1,143,154. Digital lamp control. BROWN, BOVERI & CIE A.G. 2 May, 1967 [10 Jan., 1967], No. 20321/67. Heading G4H. A hundred numbers entered in a store 1 are caused to control the amplitudes of voltages applied to corresponding ones of a hundred lamps 2 by being read out in succession by outputs 15 of counter 3 and compared in gates 9 with a range of numbers 0-31 presented in successive read-out cycles by counter 6, agreement signals passing through distributer 11 to corresponding ones of a hundred stores 13 which are reset at the end of each 32 read-out cycles to produce a succession of pulses, the lengths of which represent the numbers in the store. The pulse-length signals are smoothed and applied to lamps 2. The numbers have values from 0 to 31 and are each stored as five bits in a column 4 of core store 1. The hundred columns are energized in turn by outputs of counter 3 fed by clock pulses. When the counter changes from 99 to 0 a pulse steps counter 6. This counter is a 5-stage binary counter and counts from 0 to 31 in 32 cycles of counter 3. A stored number gives an output from comparator 9 at a certain instant in the 32 cycle period and this is applied via distributer 11, controlled by the output 15 of counter 3, to reset a corresponding one-bit store in memory 13. These are all set by the cycling pulse of counter 6 so that if a low number is stored in 1, the corresponding one-bit store is reset early in the 32-cycle period and a correspondingly short pulse is provided before the memory is reset. These pulses, one in each 32- cycle period, are smoothed in L-P filters 14 and applied to lamps 2 to adjust their brightness to the desired one of 32 values.
