Title: Improvements in or relating to computer system
Inventor: BOWTHORPE JOHN WILLIS
IPC: G06F9/308
Filed: 1968-03-27
Abstract: 1,218,656. Computers. INTERNATIONAL COMPUTERS Ltd. 12 March, 1969 [27 March, 1968], No. 14731/68. Heading G4A. A data processing system comprises a main memory 10, a subsidiary memory 20 having two data word registers 21, 22 with respective address registers 23, 24 two operand address registers 25 which supply two addresses from an instruction to the address registers 23, 24 but only to one of them if the addresses are identical, means to read a data word from main to subsidiary memory using address registers 23, 24 if the word address was not already in either of registers 23, 24, means 35 to manipulate and modify separate bytes of data words in word registers 21, 22 and means to return modified data words to the main memory. One or two operand addresses from registers 25 are placed in turn into one or two of registers 23, 24, but in each case only if neither of the registers 23, 24 already contains the (an equal) address (26, 27 are match flip-flops). The register 23 or 24 is then used to address main memory 10 to access the corresponding data word via a buffer register 13 into the respective word register 21 or 22. Bytes from registers 21, 22 are manipulated at 35 and the results returned to register 21 or 22, with a respective flip-flop 31 being set corresponding to each byte position of register 21 or 22 thus modified. The modified word is then returned to main memory 10 by reading the main memory word out to buffer 13, replacing only the modified bytes from register 21 or 22, under control of flip-flops 31, then rewriting the main memory word into main memory 10. As implied, address registers 23, 24 normally contain the main memory addresses of the data words in word registers 21, 22. If these addresses are changed from registers 25 as described above, the words in registers 21, 22 are restored to main memory first. The apparatus can be used for operating on individual bytes, or on multi-byte fields consisting of successive bytes in one or more words. For example, a multibyte field can be shifted from a position in one set of words to a position in another set. If the two sets are the same, the effect is to replicate the first byte of the source field in each byte position of the sink field.

Title: Improvements in and relating to the continuous casting of metal billets, bars, rods, tubes and the like
IPC: B22D11/00
Filed: 1941-11-18
Abstract: 552,777. Casting-machines; swash plate mechanism. HIGH DUTY ALLOYS, Ltd, HERON, J. A.. and HOCKING, L. N. Nov. 18, 1941, No. 14821. [Class 83 (i)] [Also in Group XXIV] In continuously casting bars, tubes &c. molten metal is supplied to a die 4, having an aperture of the cross section required, is cooled in this zone, and the solidifying crust is pushed, e.g. by a ring 14, so that the bar &c. emerges, i.e. to the left. The molten metal is contained in a pot 1 heated by burners at 7 and the die 4 is heated at its inlet by a graphite electric resistance 5 and cooled at 39 by jets 41, these parts being relatively heat insulated by asbestos discs 36, 37 and low conductive cast iron ring 47. The issuing rod is cooled by powerful jets 45, supported on adjustable skids and fed to a gravity roller-conveyer and finally cut into lengths. The ring 14 is connected by arms 13 to a shaft 12 which is reciprocated by a lever 15, having an adjustable pivot 16 and a motor-driven crank, not shown. In a modification the ring is given a wobble or swash-plate movement without rotating, so as to feed the bar formed uninterruptedly. This movement may be effected by carrying the ring 51, Fig. 5, on a cranked tube 53 journalled in a head 55 to turn about a vertical axis through the ring, the head 55 being carried by a yoke 56, journalled at 57 to the machine frame 10, to turn about a horizontal axis through the ring. A shaft 58 is mounted on the yoke 56 and driven through a universal joint 63, by a motor, not shown, and one crank 65 of this shaft is connected by a link 66, Fig. 6, to a fixed pivot 67. while another 72 operates in a slot in an arm 70 attached to the tube 53. This and the hollow yoke 56 may be cooled by water fed at 76. In another modification the bar is cast vertically downwards, the shaft 100, Fig. 9, for operating the wobble ring 51, being mounted, in an inclined position, in a block 112 rotated about a vertical axis by gearing 108 ... 110 and a motor 107, while rotation of the shaft 100 is prevented by securing it to a slide movable on a cross slide 113. The ring and its mechanism may be free to move vertically so that it merely rests on the solidified metal, the solid rod being drawn from the die by its weight or otherwise. In another modification the shaft 100 is fixed to a weighted telescopic shaft 152, Fig. 11, which is oscillated about its axis and has its forked end 159 oscillated vertically by a trunnioned ring 157 in which a disc 156 is rotated by a driven shaft 154 inclined and eccentric thereto.

Title: Electric systems for the automatic control of a variable condition
IPC: G05B5/01
Filed: 1936-05-28
Abstract: 476,108. Automatic control systems. TAYLOR INSTRUMENT COS. May 28, 1936, No. 15096. Convention date, May 29, 1935. [Class 38 (iv)] [Also in Group XXIX] Temperature &c.-A control system for a variable quantity or condition comprises a primary contactor moving in accordance with the condition and co-operating with two contacts to control a reversible electric motor operating correcting means, and also means which separate the aforesaid contacts and actuate a secondary contactor co-operating with two other contacts to cause further movement of the correcting means. As shown in Fig. 1, the primary contactor 10 is actuated by temperature sensitive means 8, 6 and selectively closes contacts 13, 14 which energize a reversible motor 37a actuating a valve 37 controlling the heating medium, and also, through switches opened by abutments 50, 51 in limiting positions of a support 12 for the contacts 13, 14, a reversible motor 19 wHich drives the support through interchangeable gearing and a screwed rod 25 so as to follow the contactor 10. This movement causes a secondary contactor 16 on the support 12 to energize the motor 37a to produce a further movement of the valve. The circuits of the motors 19, 37a are also controlled by switches operated by a cam 29 in continuous rotation so that the primary responses take place only when the cam raises the switches and the secondary response, which is not accompanied by any movement of the support 12 occurs in the interval. The cam is adjustable to vary the proportion between the duration of primary and secondary response periods and, in a modification, this variation may be made automatically in proportion to the deviation of the variable condition. A modification of the cam-operated switches shown in Fig. 1 is described wherein a motion of the motor 19 and support 12 in a direction opposite to that of the primary contactor is produced during the secondary response. In other modifications, the response-timing apparatus is omitted. As shown in Fig. 6, the primary response affects motors 37a and 19, and the secondary response a motor 101 only. The motors 19 and 101 are differentially geared to the rod 25 and the latter motor produces a slower drive. Thus, the secondary response tends to move the support 12 with its contacts towards the primary contactor 10 and in this way produce a secondary action of the valve motor 37a. In Fig. 7, the primary contacts control a motor 114 geared to the valve 37 through differential mechanism whereby a motor 130 controlled by the secondary contact is enabled to give a secondary movement to the valve. During primary responses a motor 19 moves the support 12 in the manner described with reference to Fig. 1. The invention is intended to produce anti-hunting control similar to that in the fluid-pressure-operated system described in Specification 425,303, [Group XXIX].
