Title: Improvements in and relating to the building of pneumatic tyres
Inventor: MENELL HANS
IPC: B29D30/32
Filed: 1963-10-30
Abstract: 1,034,887. Tyre building apparatus. CONTINENTAL GUMME-WERKE A.G. Oct. 30, 1963, No. 42763/63. Heading B7C. Apparatus for building pneumatic tyre blanks comprises two fixed annular drum sections 6, 7, and an annular, inflatable bag 1 mounted thereon, the radially outer face of which, in the uninflated state, has an axial width equal to or greater than the axial width of the unfolded carcass plies b, and is characterized by the feature that the inflatable bag 1 is secured against bodily or asymmetrical axial displacement and, when inflated, presses the parts of the tyre blank encircled by bead core rings d radially outwardly against the rings d, distance-pieces 14 being disposed within the bag 1 and being radially outwardly displaceable to determine the distance between the rings d which are supported solely by the bag. The means for stabilizing the inflatable bag comprises two series of pivotally mounted, longitudinally extensible levers 10, the free ends of which act on the interior surface of the bag 1 and are connected by two annular springs 11. The bag 1 is secured in two circumferential grooves 5 of the drum sections 6, 7, and together with these sections forms a hermetically seated cavity 8. The levers 10 are mounted in circumferentially spaced relation in bearing points 9 adjacent to and axially inwardly of the grooves 5. In operation.-When building a tyre blank, the rubber sidewall strips a, the carcass plies b, and a central crown strip c are placed on the uninflated bag 1 as shown in Fig. 1. The bead core rings d are held in the required position by members 13. Upon initial inflation of the bag 1, its radially outer surface 2 moves radially outwards until it engages the rings d. Further inflation of the bag causes the portion of the surface 2 between the rings d and axially outside the rings d to be radially extended as shown in Fig. 3, so that the tyre blank parts are pivoted about the rings d. As a result of this radial extension of the surface 2 the rings d will move axially towards each other, this motion being limited by the radially outward displacement of the segments 14. During inflation of the bag the levers 10 are forced radially outwards about the bearing points 9 by the bag wall and so hold the bag symmetrical. The radially extended, axially outer portions of the bag are forced axially inwards by annular sliding members 16<SP>1</SP> to fold the carcass ply edges and the sidewall strips a around the bead rings d to overlap the portion of the carcass between the rings d. The members 16<SP>1</SP> are then withdrawn so that the springs 11 force the bag to return to its initial inflated position. Further treatment of the tyre blank, for example, application of a tread strip may then be carried out.

A brake of the kind having a calliper 18 straddling a portion of a disc 10, movable axially relative thereto and carrying pads 14 and 15 to engage opposite faces of the disc, one pad 15 being actuated by hydraulic or other means 13 located in a limb of the calliper and the other pad 14 being brought into engagement with the disc by reaction of the calliper, has the non-actuated pad 14 bonded to a rigid backing plate 16 mounted on spaced pins 26 located in holes 27 in the calliper 18 with their axes perpendicular to the plate 16 and which take the torque on the pad when the brake is applied. The pins 26 are at the same radial spacing from the centre of the disc 10 as the centre of pressure of the pad and they engage in circular recesses or notches 28, or holes (not shown) in the backing plate offset on each side of the centre of pressure. Alternatively, they may engage at the inner and outer ends of the plate. The pins do not protrude beyond the plate so that the whole thickness of the pad may be used. The plate 17 is similarly mounted on pins 27 which do, however, protrude beyond the plate 17. The pads 14 and 15 may be of tapered thickness radially to allow for wear. The bridge portion of the calliper 18 is supported on spaced legs 19 with lugs 21 located on opposite sides of a radius of the disc passing through the centre of the calliper to which the legs are bolted.

Title: Numerical positional controls for machine tools
IPC: G05B19/25
Filed: 1970-09-09
Abstract: 1328114 Programmed control of machine tools GEORG FISCHER A G 9 Sept 1970 [12 Sept 1969] 43251/70 Heading G3N An interpolator block 4a receives programmed information from punched tape 1 via reader 2 and intermediate store 3, and pulses from a generator 16 fixed to the main carriage 8 of a machine tool driven at a predetermined speed, and provides a pulse output of variable frequency to stepping motor 14 translating cross slide 11, dependent upon both inputs, so that tool 12 follows a programmed linear or circular path. Cross slide 11 may move perpendicularly to carriage 8, or at an angle laterally inverted with respect to that shown and may carry a turret with a plurality of tools. A correction is programmed to suit a particular cut and tool, and is introduced via decade switches 27. Counters 28, 29 may be pre-set for a given diameter alteration e.g. for a press fit. For under-cutting Fig.7 (not shown) pulses to stepping motor 14 may be delayed in a storage means (not shown) until the carriage 8 has moved the required distance, and subsequently fed out at a higher feed rate until no such pulses are stored. Should the programme require reversal of the carriage 8, any over-run is counted at 30, and the programme will not proceed until reverse motion of carriage 8 causes the counter 30 to revert to zero, the count also being compensated for tool cut correction. The origin of coordinates corresponding to the start of an operation is determined by means of null print cams fixed to the machine, and emission of pulses which do not effect the operation of the interpolator as described below. Further adjustments may be made via decade counters 26. Interpolator block 4 Fig.4 (not shown). Counters (21, 22) contain members proportional to X, and a linear function of X and Z dependent on the angle Figs.2, 3 (not shown) between the two directions of motion, respectively, where the ratio X:Z defines the instantaneous direction of tool motion. Initially the counter (23) stores the negative of the number in (22). Each pulse from generator 6 causes the addition of the content of (21) to (23), and whenever the latter stores a positive or zero number, a pulse is emitted to stepping 14, and the content of (22) is subtracted from (23). Counters (19, 20) indicate the total number of pulses to reach the desired finishing position, and are counted down by the emitted pulses. Gates (38, 39) are active during circular interpolation to allow the content of counters (21, 22) to be continuously changed. The resultant tool paths for linear and circular interpolation are displayed Figs.5, 6 (not shown). A servo-system mounted on main carriage 8 may replace the stepping motor 14.

Abstract: A mixture containing a polymer and an antistatic is described which contains:   a) a polyester, a polyamide, a polyolefin or a polyacrylonitrile as the polymer, and b) from 0.1 to 20% by weight, based on the weight of the polymer, of an antistatic agent.  The antistatic agent comprises   b1) a polycarboxylic acid of the formula R(-COOH)n in which R is an n-valent hydrocarbon radical and n is the number 2 or 3, which contains from 16 to 54 carbon atoms, and b2) a polyalkylene glycol which contains on average from 5 to 50 alkyleneoxy units per molecule and whose alkylene groups are those of the formula -CHR'-CH2- in which R' is hydrogen, methyl or ethyl, where component b1) has been esterified by means of component b2). The hydroxyl number of the antistatic agent is greater than its acid number. The molar ratio in which components b1) and b2) form the antistatic agent is in the range from 1.4 to 5 mol of b2) per mole of b1); when b1) comprises only dicarboxylic acid, this molar ratio is in addition not greater than 2.5 mol of b2) per mole of b1). These mixtures containing a polymer and an antistatic have excellent antistatic properties, and their dyeability is not impaired, and possibly even improved. The mixtures can be used for the production of textile fibres.

Abstract: 1,241,746. Field effect transistor logic. NORTH AMERICAN ROCKWELL CORP. 2 Sept., 1969 [7 Jan., 1969], No. 43469/69. Heading H3T. A buffer connected between a logic circuit 2 and an output terminal 3 comprises a field effect transistor 13 having a control electrode connected to the logic circuit, an output electrode 15 connected to an output capacitance 23 and another electrode connected to a clock, feedback capacitance 14 being connected between output and control electrodes to increase conduction of the transistor. Thus, if an input signal during one phase of operation charges capacitor 14 sufficiently to overcome the conduction threshold of the transistor the next clock pulse at 16 charges the output capacitor to the clock voltage, the feedback capacitor maintaining the transistor conducting even though charging raises the output voltage above the input signal value to which the capacitor 14 was charged. 'The circuit shown is of the four phase type in which, during # 1+   2 , 7 is "on"and the inherrent capacitance of the logic circuit is charged. During # 2  8 is "on", capacitances 10 and 14 are thereby charged and 13 and 17 are "on" to connect the output to ground. During 93 the input logic discharges the capacitances or not according to the logic signals. If they remain charged then during Q 4  the output is raised above the drive level as described above, 17 discharges the output capacitance during # 2  but if this capacitance is large composed with 14, the discharge current of 14 will not greatly affect the output capacitance voltage and 18 may be omitted. Fig. 2 (not shown) illustrates a 2-phase arrangement similar to the above. The transistors may be of the MOST, MNS or MNOS types.
