Title: Improvements in or relating to the cementing of moulded methyl methacrylate resins
IPC: C08J5/12
Filed: 1943-02-03
Abstract: Pieces of moulded methyl methacrylate resin are cemented together by applying a cement to the surfaces to be joined, whilst they are not more than 10 DEG  C. below the "unmoulding temperature," the cement comprising a liquid which is a solvent for the resin at said temperature and having a boiling point above it, bringing the surfaces together and holding the pieces together whilst cooling them.  The "unmoulding temperature" is the lowest temperature at which exposure of the piece of moulded resin, for a period long enough for it to be heated throughout, will cause distortion thereof. The term methyl methacrylate resin includes resins obtained by polymerization of methyl methacrylate alone or in admixture with a minor proportion of other polymerizable materials, e.g. other esters of acrylic and methacrylic acids, vinyl esters, styrene; and also includes such resins having incorporated therein auxiliary ingredients, e.g. plasticisers, lubricants, colouring materials.  The cement may also contain a thickener, e.g. polymethyl methacrylate or pyroxylin.  Specified liquids for the cement are butyl lactate, xylene, methacrylic acid, cyclohexanone and benzyl alcohol.  In examples, cements specified are (1) butyl lactfte with pyroxylin or polymethyl methacrylate; (2) xylene alone or with polymethyl methacrylate; (3) methacrylic acid alone or with polymethyl methacrylate; (4) cyclohexanone; and (5) benzyl alcohol alone or with polymethyl methacrylate.  Examples are given of the cementing together of pieces of moulded resin consisting of (1) polymethyl methacrylate and a small proportion of (a) stearyl alcohol, or (b) dibutyl phthalate, and (2) a copolymer of methyl methacrylate and styrene with a small proportion of stearyl alcohol.

Title: Improvements in the purification of sulphur
IPC: C01B17/02
Filed: 1930-01-18
Abstract: Crude sulphur, when free from tarry constituents is purified by heating in the solid or liquid phase with mineral acids, such as sulphuric, hydrochloric, nitric or phosphoric acids, of medium concentration e.g. 40 to 50 per cent.  Where the impurities consist mainly of ferrous sulphide, sulphuric acid of a specific gravity of 1,40 may be employed.  When tarry matters are present, nitric acid or nitrous fumes may be employed or strong oxidizing agents, such as chromic acid, permanganates, perchlorates, or persulphates may be added to the acids.  The sulphur may be in a finely divided form or in the liquid state at temperatures between 120 DEG  and 160 DEG  C., the increase in temperature being made possible by increasing the pressure, by using acid of the necessary strength or by additions to the acid, such as sodium sulphate or calcium nitrate in the case of sulphuric and nitric acids respectively.  Intimate contact between the sulphur and the acid must be effected as by vigorous stirring or by the introduction of inert gases.  Examples are given of the use of sulphuric acid and potassium bichromate, sulphuric and nitric acids, sulphuric acid and potassium persulphate or sodium perchlorate, and sulphuric acid alone.  Specifications 5838/11, 8097/12 and 10147/12, [all in Class 90, Non-metallic elements], are referred to.

Filed: 1928-01-21
Abstract: 286,638. Associated Telephone & Telegraph Co., (Assignees of Sengebusch, H.). March 7, 1927, [Convention date]. Automatic exchange apparatus.-In a rotary stepping switch an arc-shaped contact bank support is adjustably secured to the switch frame, and a plate carrying a set of relays with their armatures and spring assemblies is detachably connected to the switch frame. A mounting for the armature of the driving magnet, an interlocking device for line and cut-off relays, and forms of wipers and back contacts are also described. An arc-shaped plate 4 to which the contact bank assembly is bolted, is secured :o the switchboard by lugs 48, 49, the switch frame 3 being detachably and adjustably connected to the plate 4 by bolts 10, 11 engaging slots in the plate. The contacts 40 - - 43 of a set are staggered at their outer ends as shown. The wipers 60 - - 63 are double-ended (only one end being shown in Fig. 1), so that when one end is in engagement with the first set of contacts, the other is one step away from the last set. The contact edge of the test wiper is slightly elongated so that it still engages one contact after being advanced to engage the next one. Electrical connection with the wipers is effected through brushes such as 63<1>, Fig. 2. The switch rotates in the same direction during setting and release, and when the wipers reach normal and engage the contacts 23, the circuit of the driving magnet 5 is broken at the springs 64. 65, Fig. 2. actuated by an arm 35 on the wiper shaft. A numbered disc 37 on the wiper shaft indicates the position of the wipers. The armature 6 of the back-stroke driving magnet 5 has a knife edge resting in a V-shaped groove formed by the end of the heel piece 26 the projecting portion of a plate 17 secured thereto, and the tensioning spring 7 is connected to a plate 19 on the armature, and to a member adjustably connected to a plate 17, the, stroke of the armature being adjusted by a screw 9. Lugs 36, 36<1> on the plate 17 prevent lateral movement of the armature 6. A resilient stepping pawl 8 is rigidly secured to the armature 6, which also carries an insulated bush 66 for actuating the interrupter springs 24, the backward stroke of the armature being limited by a stop 22. The line and cut-off relays 51, 50 are mounted on a plate 2 detachablv secured at 15, 16 to the switch frame 3, their armatures being provided with an interlocking device comprising a spring bar 52 bolted at 53 to the plate 2 and formed with a forked end 56, 57. The part 57. adjacent the armature 54 of the line relay, is inclined so that if this relay is energized first, as upon initiation of a call, the interlocking device is displaced so that the part 56 lies clear of the armature 55 of the cut-off relay, which is thus free to pull up. If the cut-off relay is energized first, as in an incoming call, full movement of its armature is prevented by the part 56 to avoid energization of the line relay.

Title: Microprogrammable control memory diagnostic system
IPC: G06F11/22
Filed: 1974-01-16
Abstract: 1459851 Diagnostic testing for microprogram XEROX CORP 16 Jan 1974 [22 Jan 1973] 02034/74 Heading G4A A processor, e.g. CPU or I/O processor, which is microprogrammed by a control store, is tested at regular intervals by a microprogram in the control store which causes circuits within the processor to be exercised and any fault information generated as a result to be stored in a fault register from which the information is subsequently transferred to main memory. The main memory may then be accessed from a remote data terminal to retrieve the fault information. The test microprogram described tests an I/O processor which includes a random access working memory 251 addressed by a device number to memory address converter 259, an arithmetic unit 252, data register 254 and a byte selector 260 which multiplexes bytes on to the device I/O bus 262. The microprogram tests the ability of the processor to circulate all 0 and all 1 words round loops including AU 252, Memory 251, multiplexer 250 and register 254. A test is also made of the byte count function (an I/O command specifies a start address in main memory and the number of bytes to be transferred). Faults detected by the test microprogram cause an interrupt of the CPU which remains in a wait state until all the required fault information has been logged. A fault register is loaded with a first field indicating the unit in which a fault occurred, and a second field indicating the nature of the fault. The second field may be divided into a first sub-field indicating fault mode and a second sub-field indicating fault information unique to the faulty unit. A separate fault register is provided in the CPU to record fault information relating to the CPU. The error data recorded in memory may include information as to how the error was detected, date, time, program (job number), program status word and the fault register contents. Device number and device status may also be recorded for an I/O fault. The contents of the CPU fault register may be displayed at the CPU console. Parity checking and microprogram branching are also described, the parity generators, like the microprogram store, using read-only integrated circuit chips.

Title: Improvements relating to the production of turbine or compressor blades
Inventor: HIGNETT HAROLD WILLIAM GEORGE
IPC: B21C23/16
Filed: 1957-01-21
Abstract: 830,472. Making turbine and like blades; extruding. WIGGIN & CO. Ltd., H. Jan. 21, 1958 [Jan. 21, 1957], No. 2153/57. Classes 83 (2) and 83 (4). A turbine or compressor blade having an integral root and longitudinal cooling passages is made by forming a billet, Fig. 3, with longitudinal holes of greater cross-sectional area over part of their length 2, than over the remainder 2<SP>1</SP>, inserting a filler into the holes, deforming some or all of that part of the billet with a greater size hole to form a blank for the blade portion, and then removing the filler. The holes may be drilled from one or from opposite ends of the starting billet using different diameter drills, Fig. 6 (not shown). In another embodiment a starting billet 1, Fig. 1 (not shown) has longitudinal holes 2 of uniform diameter drilled wholly or partly therethrough. The holes may then be deformed into elliptical section, Fig. 5 (not shown), by rolling the billet as described in Specification 826,152. The billet is then partially extruded from a container 3, Fig. 2, through a die of rectangular section 5, by means of a ram 4, whereby the filled holes 2<SP>1</SP> in the extruded part are reduced in size. The unextruded part of the billet is then machined to provide a billet of uniform section, Fig. 3, and this billet is partially extruded by a ram 7, Fig. 4, from a container 6 through a die 8 of roughly aerofoil section to form the blade portion. Alternatively the blade portion may be formed by rolling. The blade portion with its fitted holes 2<SP>11</SP> is then formed into its final profile by rolling, die-stamping or machining. In another embodiment the starting billet 13, Fig. 7, is cut from a bar 12 of T-section. Holes 14 of uniform section are drilled and the head portion of the billet is then extruded by means of a ram 16, Fig. 9, through a die 17 whose orifice has a cross-section substantially the same as the leg portion 13 of the billet which leads during the extrusion. The holes 14<SP>1</SP> in the extruded head portion are thus reduced. The resultant billet, after trimming off at X-X, is then partially extruded through the die 8, Fig. 4. The leg 13 may be tapered so as to produce tapered cooling passages in the final blade. When a shroud is required at the tip end the holes are blind at the leading end of the billet and the blind end is subsequently deformed to the shape of the shroud.
