Title: Combined squeezing and jolting device for inverting moulding machines
IPC: B22C15/30
Filed: 1961-06-16
Abstract: 971,116. Moulding machines. MALCUS HOLMQUIST A.B. June 16, 1961 [Sept. 27, 1960], No. 21917/61. Heading B3F. An invertible squeezing and jolting machine comprises an invertible jolting table 10, an invertible main cylinder 6 in which a squeeze cylinder 7 is reciprocable and an anvil stock 13 reciprocable in the squeeze cylinder and supported by a spring 14 therein, the anvil stock forming a cylinder for a jolt piston 15, the upper part of which jolts the table 10, the piston and anvil stock being formed with channels 22-29 which act as valves so that compressed air supplied to the interior of the jolt piston is supplied and discharged at high frequency to the space between the bottom of the jolt piston and the anvil stock, so that they are given a relative reciprocating movement which causes the jolting action. The movement of the squeeze is independent of the jolt piston and is effected by compressed air.

Title: Improvements in or relating to aluminized steel articles and methods of making the same
IPC: C23C10/60
Filed: 1934-07-26
Abstract: A steel article for use at temperatures normally not in excess of about 1500 DEG  F. is provided with an aluminized surface, the concentration of aluminium being between 5 and 35 per cent at the surface and tapering off gradually into the body of the steel. The surface is substantially free from chromium, i.e. does not contain more than 3 per cent of this element.  Articles referred to are oil still tubes, superheater tubes, automobile exhaust piping, other parts of the exhaust system in automobiles, e.g. the muffler and exhaust manifold, coke still bottoms, bolts for use in furnace construction &c., and heat-exchanger and condenser shells. The surface is preferably obtained by providing the article with a surface layer of high aluminium concentration by the usual calorizing process, e.g. heating at 1600-1800 DEG  F. in a mixture of aluminium powder and a large amount of inert material, e.g. aluminium oxide, and then subjecting the article to a prolonged heat treatment.  The heat treatment is preferably carried out at about 1800 DEG  F. for a period of from about 24-48 hours, according to whether a light or a heavy calorized coating has been applied. The heat treatment causes the aluminium to diffuse and also results in a grain growth of the steel which increases its resistance to creep at high temperature. In some cases when the article is subsequently to be deformed in the cold, the heat treatment may be followed by a soaking for about 12 hours at the lower critical point to refine the grain, the article then being cooled in air.  In order to avoid the necessity for soaking the article may be calorized at a temperature below the critical point to produce a light aluminium deposit which is then diffused by a heat treatment at a temperature below the critical point, e.g. for 12 hours at about 1600 DEG  F.  Alternatively, the desired surface concentration of aluminium may be obtained by combining the calorizing and heat treatment, for example, by calorizing at a temperature below the critical point for a period of from 24-48 hours, or by calorizing for 8-16 hours at about 1800 DEG F.  In the latter case a soaking at the lower critical point is necessary to refine the grain.  Alternatively, the aluminium may be applied to the surface of the article by spraying or hot dipping, and the article then heated at about 1800 DEG  F. for more than 100 hours. The steel may be an alloy steel containing about 0,08-0,18 per cent of carbon and about 0,25-2,5 per cent, preferably 0,5-1 per cent, of molybdenum with or without about 0,25-2,5 per cent, preferably 1-1,5 per cent, of chromium. The low surface concentration of aluminium allows the articles to be deformed either by hot or by cold working without damage to the protective layer.

The apparatus.-The memory 11 comprises four words or registers K, A, B, C each containing 16, 4 bit, BCD digits. The registers K, A have their addresses interchanged by units 23, 29 thus avoiding physical interchange of the contents and this may be used in multiplication and division operations. Numeric and control data is entered on keyboard 31, the numbers are temporarily stored in instruction register 33, passed to arithmetic register 35 and thence to memory 11. The control data passes through decoder 34 to logic means 21 which selects stored logic instructions, using unit 41, for controlling operations. A printer 53 is also provided. Overflow errors may be detected. The Keyboard (Fig. 2, not shown).-Decimal numbers are entered on a listing keyboard and encoded in 8-4-2-1 BCD and a control keyboard has keys for effecting the four rules of arithmetic.

The printer (Fig. 24, not shown).-A drum is rotatable about a shaft and has characters arranged in rows and columns on the face thereof, and a print hammer traverses the drum to print data on a recording medium under control of the calculator. The printer is synchronized with the calculator using row synchronization pulses stored in the arithmetic register 35.  Addition.-The augend is in accumulator B and the addend in word K. The first digit from B is transferred to the AR35, the first digit of the addend examined by logic 51 and a number of pulses equal to the addend first digit is applied to AR35 to be added to the augend digit. The sum of the two digits is then sent to accumulator B and the process repeated for the remaining digits. Any carry produced counts the next addition up by one in AR35. Subtraction.-This is similar to addition only the pulses are subtracted in AR35 and 10's complementing may occur. Multiplication.-The multiplicand is added a number of times equal to the least significant digit of the multiplier to form a partial product. This partial product is shifted right one place and added to the next partial product which is formed using the least significant but one multiplier digit, and so on. Division.-This is effected by repeated subtraction and shift.

Title: Improvements in or relating to telephone systems
IPC: H04Q3/00
Filed: 1934-03-15
Abstract: 435,379. Automatic exchange systems. AUTOMATIC ELECTRIC CO., Ltd., Strowger Works, TAYLOR, R., 30, Oulton Road, Wavertree, both in Liverpool, and BAKER, G. T., Blackbrook, Caerphilly, Glamorgan. March 15, 1934, No. 22565/35. Divided out of 435,313. [Class 40 (iv)] A bi-directional final selector is released by rotary stepping out of the bank and the circuit for the rotary magnet includes off-normal contacts, rotary interrupter contacts and back contacts of the test relay and of a slow relay operated by the line relay. The selector described is adapted to be taken into use by one or other of the group selectors described in Specification 435,313, and the Provisional Specification refers to Specifications 391,123, 429,767, 432,281 and 433,877. On seizure of the selector, A, B and C pull up and the tens digit is repeated to C and magnet VM in series. When C falls back at the end of the digit, E pulls up to re-operate C and change over to the rotary magnet RM, the units digit being repeated to C and RM in series. During the digit, E holds dependent on C which falls back at the end of the digit, and during the slow period of E, H (upper), tests the wanted line. If the wanted line is free, H pulls up, locks over its lower winding in series with a relay in the group selector which thereupon initiates ringing. The operation of H followed by the release of A and B completes the speaking path at the final selector. If the wanted line is busy, relay E on its relapse connects ground to the third wire to release the test relay in the group selector, the busy signal being transmitted from that selector. On the relapse of E, C is reoperated over its upper winding and in case of a toll call, ground from the group selector on wire SW operates H in series with RM to switch through, C falling back when A and B release, and the call being offered as described in Specification 435,313.

When the calling party releases the group selector, ground is removed from wire SW so that H falls back to complete the self-interrupting release circuit of the rotary magnet over common conductor 40. Unobtainable numbers. The third wires of spare lines are connected to idle battery and the positive wires to ground, so that H switches through as for an idle line and the group selector prepares the ringing circuit. Relays E, A and B fall back and C, re-operating during the slow period of B, connects the ground on the positive wire to A (upper) which holds C since B does not re-operate. N.U. tone is thus connected to the negative wire and the superposed battery operates the ringing trip relay at the group selector to extend the tone back to the calling line.

Abstract: 506,258. Photo - mechanical colour printing processes. INTERCHEMICAL CORPORATION. Aug. 24, 1937, No. 23217. Convention date, Sept. 4, 1936. [Class 98 (ii)] In processes in which colour separation records are produced by photograph - ing the subject through colour filters, making printing plates from these records and printing in superimposition from the plates, colour filters and photographic plates are used, the spectral characteristics of the combined filters and plates being based not on the spectral qualities of the materials used for printing but on the spectral qualities of the differences in colour of combinations of pairs of the coloured materials produced by slight changes in the amounts of one of the coloured materials in each pair. The coloured materials may be selected on the basis of differences produced in each of several combinations of the coloured materials produced by slight changes in the' amount of one of the materials. In carrying out the process, a set of triangular half-tone plates is used having a main area m and a subsidiary area s having a slightly greater percentage of half-tone dots per unit area, a series of such plates having different percentages of half-tone dots in the main area being provided. An area of the original, the colour of which is to be matched, is selected and three plates are chosen which when inked with the inks to be used give the best match in the main area. A print as shown in Fig. 5 is then made, the plates being turned through 120 after the printing of each colour so that the area A reproduces the desired colour and areas B, C, D show the effect on the same colour of using a slightly higher percentage of half-tone dots in printing with one of the inks. Comparison of each of the areas B, C, D. with the area A determines the spectral characteristics of the combined plate and filter for reproducing the component colour corresponding to each of the inks. For selecting an ink, sets of prints are made using two standard inks and the ink to be tested, from a, series of plates of differing,dot density and the spectral characteristics of the primaries are determined . from these. The process is repeated with other inks to be tested and the ink giving the more uniform results is chosen. In carrying out the tests, the prints are made on material similar to that on which the printing is to take place and, if necessary, a black key plate may also be used.
