Patent GB-392115-A (GB)
Title: Improved method of making articles from rubber dispersions
IPC: B29C41/14
Filed: 1932-12-16
Abstract: Articles are made from aqueous dispersions of rubber and the like by a non-electrophoretic process characterized in that the mould is coated with a water-insoluble finely divided, inert material which isolates the dispersion from the mould and also serves as a venting medium to allow the escape of any small bubbles of air which would otherwise blemish the article. Suitable materials are substances which are in plate-like or needle-like form, such as mica, graphite, diatomaceous earth, slate flour, soapstone and magnesium carbonate. These are preferably applied in paste form suspended in a volatile vehicle such as an alcohol or a ketone and part at least of the liquid vehicle is then removed to make a non-flowing stratum on the surface of the mould.  The prepared mould may be coated with a coagulant or a coagulant may be added to the suspension before it is applied to the mould, or a coagulant may be sprayed on the stratum in addition to its incorporation in the stratum.  An example of a suitable coating material is 200 grams of finely divided soapstone in 1000 c.c. of methanol.  The insertion of this stratum between the mould and the dispersion obviates blemishes due to grease spots &c. on the mould surface, and facilitates the removal of the finished article.

Title: Improvements relating to locking systems
IPC: E05B35/08
Filed: 1938-12-07
Abstract: 522,385. Locks. FUTRAN, S. Dec. 7, 1938, No. 35681. Convention date, Dec. 10, 1937. [Class 44] On a rotary cylinder 2 there are positioned a number of rotary locking discs 4 each recessed at 6, 7, 7<1>. Spacing partitions separate the discs which are held against frictional rotation by spring-presse d pivotal pawls 9. A shaft 14 carries an oscillable feeler 15, 16 and also a hook 18, 19 which may be brought into the path of pins 20, 20<1> on a disc 21 keyed to the cylinder 2. In the zero position, Fig. 6, the feeler 16 engages in a line of recesses 6 thus rocking the hook 19 away from the pins 20, 20<1>. On inserting a key 27 and turning the same, certain discs 4 are turned whilst those opposite notches 28<1> remain in normal position. Due to the movement of certain discs 4 the feeler 16 is raised thereby bringing the hook 19 into the path of the pins 20, 20<1>. After 180‹ turn the key may be removed, leaving a certain locking combination of discs. This combination can only be operated to unlock the cylinder 2, and thence actuate the bolt-operating member 10, by a key similar to that first used, which will move either recesses 7 or 7<1> into line with recesses 6 in the discs not moved, for either direction of rotation and independent of the number of rotations, to bring about the unlocking action, Spring- pressed pips 22, 23 engage with notch 30 in the key to enable'the cylinder 2 to be turned and notches 29, 29<1> co-operate with a projection 31. on the key allowing insertion only at those two points. A removable screw may be provided over notch 291.

Abstract: 1325042 Vehicle tyre studs STAHLGRUBER OTTO GRUBER & CO 23 July 1970 [26 July 1969] 35819/70 Heading B7C A stud for motor vehicle tyres comprises a casing of synthetic plastics material, a reinforcing jacket embedded in the casing and a hard metal pin centrally disposed in the jacket, the jacket having a pair of opposed edges which meet along a line of contact or overlap to form a seam 16, Fig. 4. A reinforcing jacket 25, Fig. 7, may be rolled from a sheet metal blank 17, Fig. 6. The blank comprises a jacket section 19 surrounding a hard metal pin 18. Several tongues 23 reinforce hose 20 of synthetic plastics material and transition portion 21 from the base to stem 22. Edges 24a and 24b of the blank 17, Fig. 6, are cut at a slant to provide a transverse line of contact between them. Synthetic plastics material penetrates through holes 26 when the outer plastics casing is applied to the hard metal pin 18. The centres of the holes 26 and the centres of indentations 27 are situated on lines parallel to the edges 24a, 24b. Indentations 27 centre the pin 18. Further indentations 28 comprise bent portions 29 and cuts 31. Spaces 32 between tongues 23 are extended to form indentations 33 with bent edges 34 and cuts 35 between indentations 28. A flange 36 on the pin 18 is secured against axial movement by lugs 37 formed by indentations 28 and lugs 38 formed by indentations 33. A reinforcing jacket having a substantially triangular cross-section may surround a metal pin 43, Fig. 10. The distance between a leg 58 and a rounded opposite corner 59 is such that there result centring surfaces 60 for the pin 43 and centring indentations are rendered unnecessary.

Abstract: 1,160,781. Continuous casting. PHELPS DODGE CORP. 10 Aug., 1966 [20 Aug., 1965], No. 35898/66. Heading B3F. [Also in Division F4] To cast a thin sheet 58, e.g. of foil thickness molten copper 57 flows continuously from a molybdenum tray through a channel 61 over a lip 52 (with, except at its ends, a tungsten surface 54 wettable by the copper) on to a moving surface 56 such as an endless belt, or the steel (possibly chromium-plated) surface of rotating drum, on which it is cooled by gas flowing in a hollow shaft of the drum and solidified before being stripped from the surface. The apparatus is in an enclosure containing argon (at subatmospheric pressure), nitrogen or a vacuum. First, the channel 61 is heated by a bar element 51 and the tray is heated by surrounding heaters, Fig. 2 (not shown). A stop bar (44) is then raised to tilt back the pivotally-mouned tray (31) by raising its channel-end (while molten copper is poured into it) and is then lowered to start the flow out of the mouth (M) before being raised to operating level. The tray and molybdenum upper lip 53 of the mouth M are heated, as before, during casting. The tray is continuously replenished from a heated vessel (21), Fig. 1 (not shown) and a gas jet (13) strips the cast sheet from the drum (11).

Abstract: 1,016,979. Electric selective signalling. INTERNATIONAL BUSINESS MACHINES CORPORATION. Sept. 7, 1964 [Sept. 30, 1963], No. 36629/64. Heading G4H. In printer control apparatus, representations of characters to be printed are read cyclically from a first store and compared with representations of characters mounted on a movable type carrier read from a second store in synchronism with the respective type characters appearing in the printing position, printing being performed on a positive comparison being obtained. In the particular embodiment, a line of 128 characters is printed using a constantly moving type chain bearing 256 characters, and 128 hammers. As the chain moves by one type element, 8-bit representations of the 128 characters to be printed are read in turn from a first core store and compared with corresponding ones of 128 8-bit representations of the type character in position read from a second store. The comparator output is passed to 128 hammer selection gates enabled in turn by a matrix controlled by the addressing circuits of the first store. The second store may be a core store or a replaceable fixed store. After these 128 read-outs, the addressing circuitry of the stores is advanced by one by a pulse from a magnetic clock-pulse track driven in synchronism with the type chain. After printing of one line, a single mark on a second magnetic track driven with the type chain produces a line synchronization pulse to ensure that store read-out for the next line starts at the correct time. In a modification, a 6-bit code group is stored in the first store for each character to be printed, and a sequence of characters is preceded by one of four 6-bit code groups to identify the character variety (e.g. whether arabic or latin letters or &c.). This latter group is recognized to provide an extra 2-bit control signal for the comparator (no details).
