Abstract: 1372397 Rolling metals MOELLER & NEUMANN GmbH 23 Nov 1971 [28 Dec 1970] 54376/71 Heading B3M [Also in Division B8] A cooling bed for rolled material includes a support grating 10 which is'movable relative to a fixed grating 20, the grating 10 being movable both horizontally and vertically by a single drive shaft 30 which carries cams 32 and 40. The grating 10 comprises supporting bars 11 carried on beams 13 and posts 15, whereas the grating 20 comprises bars 21 mounted on fixed posts 22. To move the beams 13, and hence the grating 10, horizontally, a roller 36 carried by a post 34 co-operates with a cam track 32a of the cam 32. To move the grating vertically, the cam 40 engages rollers 42 supported on the ends of push rods 44 and 52, the rods co-operating at each end with inclined ramps 47, 43, 51 and 55 so that horizontal movement of the rods is transmitted into vertical movement of the grating. A set of rollers is arranged at each end of each rod so that the posts 15 can move horizontally on one roller, while two further rollers independently co-operate with a ramp to produce vertical movement. The path of movement of the grating 10 may be as shown in Fig. 4, but it can readily be modified by changing the cam profiles. By inclining one set of bars 11, the weight of the bars can be used to urge the roller 36 against the cam 32, and a cam track can be dispensed with.

Filed: 1974-12-19
Abstract: 1469299 Data processing OLYMPIA WERKE AG 19 Dec 1974 [22 Dec 1973] 54998/74 Heading G4A A circuit arrangement has a chip 18 including a computing and control unit and a number of memory chips 22-24 each of which includes a memory 29 and an associated address register 25. Each address register 25 normally counts clock pulses; when the address location in the memory 29 contains a jump instruction the jump instruction is transmitted via a data bus 19 to the computing and control unit; if the jump address is in the memory from which the jump instruction is read the computing and control unit causes, via a control bus 21, a circuit 35 to transfer the jump address from memory 29 to address register 25; if the jump address is in a memory other than that from which the jump instruction is read out the computing and control unit provides a selection address on an address bus 20 which is decoded at 33, the rest of the jump address being provided on data bus 19 to the address register identified by the selection address. Each address register may be split into two parts an eight-bit part (55, Fig. 3, not shown) receiving an address from the data bus and a two-bit part (57) receiving an address from the address bus. The computing and control unit includes a linking unit (117, Fig. 5, not shown) receiving a first operand from a first register (122) and a second operand from a second register (123) or a random access memory (110). The random access memory may be addressed by two threebit registers (111, 112), one (112) of which receives counting pulses or by four bits in an instruction register (114). If the instruction register (114) provides the address "12" to the memory (110) this indicates that the memory is to be addressed with the contents of the threebit registers (111, 112). If the instruction register provides the address "13" or "14" to the memory this indicates that the memory is to be addressed with the contents of the three-bit registers and that one of these registers (112) subsequently counts backwards or forwards, respectively. Each memory chip including a read only memory (150, Fig. 6, not shown) also includes an address register (157) which normally counts counting pulses; if an addressed byte contains a jump instruction the jump address is transferred into the address register and a further register (160) contains the interruption address plus 1; this may be extended by the use of two further registers if the sub-program contains a jump instruction.

Alternatively, the device may be formed from a sheet of metal-impregnated silicon rubber followed by a stamping-out operation, or by laminating two sheets of the silicone rubber to form a composite sheet with a different metal incorporated in each original sheet, again followed by stamping-out the devices. Etching or abrading may be necessary after such a step to ensure exposure of the metal powder, and also barium sulphate may be compounded with the rubber in order to facilitate X-ray detection. Further, known intra-uterine devices may be coated with at least two differing metals, or thin coils of the metals may be wound around the devices, or alternatively, metal powder may be incorporated in the material of these known devices.

Binary data signals input to a register Rs are shifted four bits at a time to a register R whence they pass via a memory circuit M to decoders DC ; Dc outputs a pulse Si, Fig. 3c, which is the display signal in the ith position to be displayed on the ith display device by a display timing signal Dti, Fig. 3a: Si passes through gates A to a drive circuit Dr. Gates A are periodically disable by blanking pulses Sb, Fig. 3e from a circuit Bc comprising a ring counter Bt 1 -Bt 4 , F 1 -F 3  and IGFETs T 1 -T 3 . These pulses are timed to occur at the borders of signals Dt, S (as shown in Figs. 3a-3e) so that any lack of synchronism therebetween (e.g. as shown at X, Fig. 3c and Y, Fig. 3d) is masked by the gates, which are however enabled frequently enough and long enough between pulses Sb for the normal persistence of vision display to operate.

Abstract: 1283936 Making hollow-ware; stamping; working at specified temperatures INTERNATIONAL BUSINESS MACHINES CORP 24 Nov 1969 [13 Dec 1968] 57309/69 Headings B3A, B3Q and B3V [Also in Division C7] A method of forming an article from a blank of metal which can be conditioned to exhibit superplastic behaviour, comprises treating a selected portion or portions of the blank before the forming operation to lessen or destroy its super plasticity in the portion or portions treated. As applied to forming a sheet 22 of a superplastic stainless-steel or a 78-22 Zn-Al alloy in a die 20 by differential fluid pressure applied across the sheet, the sheet is clamped over the die by a ring 24 and screws 26. An electric heater 28, 36 is moved on to the sheet which is locally heated to a temperature high enough to destroy or reduce the effect of pretreatment for superplasticity before the heater is switched off and the sheet air-cooled to below the critical temperature for superplasticity (about 530‹ F. for the Zn-Al alloy). The heater is then raised and the whole sheet conditioned by heating to the critical temperature by means not shown before being formed by vacuum below the sheet or pressure applied from above. In the formed article, Fig. 3 (not shown), the thickness of the area (34) where the influence of pre-treatment was destroyed remained unchanged. Overheating and conditioning for superplasticity may be effected before the sheet is applied over the die. In another example, Fig. 6, after clamping the sheet it is first made superplastic by heating with hot air to 520‹ F. and then deflected against the stationary heater 28<SP>1</SP> by pressure within the die 20. The part in contact with the heater is raised above the critical temperature before the sheet is vacuum-formed. One or two pumps 42<SP>1</SP> may supply the pressure and vacuum. Some superplasticity may be allowed to remain in the overheated area by controlling the temperature and time of overheating. Heat-treatment apparatus for conditioning a 78-22 Zn-Al alloy sheet 72 which is to exhibit superplasticity in some areas when reheated to just below the critical temperature of 532‹ F., and less or no superplasticity in other areas, comprises blocks 60, 62 hinged together at 68 and pressed against the sheet by a spring 70. Electric heaters 74, 76 heat the blocks 60, 62 and the sheet 72 to above the critical temperature before they are immersed in a bath 80 of cooling liquid. Fast quenching (room temperature in 5-15 seconds), necessary if the ability to exhibit superplasticity is to be maintained, occurs at those parts of the sheet which are not in contact with the blocks 60, 62. The parts in contact quench more slowly and have a reduced or no tendency to become superplastic when re-heated. The ability to exhibit superplasticity may be reduced or destroyed in selected areas of the Al-Zn alloy sheet by electroplating these areas with copper and holding the sheet at an elevated temperature to diffuse the copper into the sheet.
