Title: Method of and apparatus for forming an embossed pattern in the tread band of a pneumatic tyre
IPC: B29D30/68
Filed: 1962-06-28
Abstract: 1,015,192. Moulding tyres. PIRELLI S.p.A. June 28, 1962 [July 7, 1961], No. 24821/62. Heading B5A. In forming an embossed pattern on a pneumatic tyre tread, the article is rigidly enclosed on all surfaces except the peripheral surface, which is then subjected to centripetal pressure from a plurality of rigid surfaces. Fig. 3 shows a mould comprising a lower annular section 8, an upper section 15 and a central section comprising a plurality of sectors 9, whose inner faces form the tread bond of a tyre 37. Each sector 9 is mounted on a support 10 provided with an inclined plate 12, which slides on a second inclined plate 13 attached to a supporting ring 14. A plate 7 moves relative to the ring 14, lifting section 8 and sectors 9, and as plate 7 rises sectors 9 move centrifugally. With the mould in this open position and upper section 15 withdrawn, the partly pre-shaped tyre 37 with a curing-bag 38 fitted is placed in the lower section 8 of the mould, and upper section 15 is lowered (see Fig. 3) to touch section 8. The force which lowers section 15 overcomes the hydraulic system supporting plate 7, and the mould descends, causing sectors 9 to move centripetally. At the same time fluid is admitted to curing-bag 38 so that when the mould is fully closed, the pressure within the tyre exceeds the centripetal pressure of sectors 9. The tread of the tyre being thus formed, the pressure within the curing-bag is increased and steam admitted to surround the mould (i.e. into container 2, Fig. 1, not shown). Fig. 2 (not shown) illustrates the mechanism used to lower the upper section 15 vertically. Fig. 5 (not shown) shows similar equipment to Fig. 3, but using a different form of curing-bag 54, which is applied to a tyre 55 with the mould open, by slowly withdrawing a cylinder 51 in response to fluid pressure in the bag 54. At the same time an upper section 47 is lowered as described above until a plate 48 contacts supports 42 of sectors 41. Further lowering depresses plate 39 so that the sectors move centripetally. A third embodiment (Fig. 6) has a cylindrical curing-bag 67. Starting with the mould, comprising a lower section 57, upper section (not shown) and sectors 58, open as shown, a tyre 72 is placed in position with a rigid cylindrical sleeve 71 resting on its upper bead. A disc 66 is lowered and fluid admitted to bag 67 which slides free of sleeve 7] to contact the tyre 72. The sleeve is removed, the upper section lowered, and the rest of the forming proceeds as above.

Title: Logic circuits

Filed: 1968-05-24
Abstract: 1,220,839. Logic circuits. TELEFUNKEN PATENTVERWERTUNGS G.m.b.H. 24 May, 1968 [24 May, 1967], No. 24947/68. Heading G4A. An electronic logic module 1 has inputs and outputs as in Fig. 1. Fig. 6 shows the module 1 constructed from five known circuits 11-15, each involving transistor differential amplifiers, a two-emitter transistor and transistor emitterfollowers, and each performing the function the module 1 being part of a larger module 2 also having further such circuits 2a, 2b, 2c each of which passes a respective input X<SP>1</SP>, Yl or Z<SP>1</SP> in true or inverse form or replaces it by 0 or 1 depending on a respective two-bit control signal 2a1, 2b1 or 2c1. Fig. 5 shows a series of the modules 2 in a parallel arithmetic unit, the inputs X<SP>1</SP>, Y<SP>1</SP>, Z<SP>1</SP> being fed from registers D, A or B, and U or V respectively, the outputs R, S, T feeding registers A or B (with a one-bit displacement to low order), A or B, and U or V respectively, via switches which are controlled so that a register does not both supply and receive bits simultaneously. The c inputs and C outputs are connected as shown, and the R output of the lowest-order module 2 0  feeds a shift register MQ. Operations possible are: (a) Bit-by-bit ANDing of two operands e.g. for masking. (b) Bit-by-bit ORing of two operands. (c) Adding two operands. (d) Transfer of one operand with a one-bit shift to low order (rightwards). (e) Parity checks. (f) Multiplication by successive addition with shift under control of successive individual multiplier bits from register MQ applied to the control inputs 2a1 (e.g. 2ia1), the multiplicand being applied from register D to inputs X<SP>1</SP>. The outputs R and T are applied to registers B and V respectively on alternate cycles and to registers A and U respectively on the other cycles, the inputs Y<SP>1</SP>, Z<SP>1</SP> being fed in a given cycle by the pair of registers B and V or A and U which were fed from outputs R and T in the previous cycle. The shift is provided by the way the outputs R are connected to registers A, B. The lowestorder R output feeds register MQ which finally holds half the double-length product. A final cycle is used to add in remaining carries. (g) Division is by repeated subtraction followed by shift but the result of a subtraction giving a negative remainder (indicated by the value of the high-order carry output C n ) is discarded and the minuend used in this subtraction (still in existence in register A or B) is shifted and then used as the minuend in the next subtraction. A further embodiment has two modules 2, each feeding the other via storage elements.

Abstract: In the hydrogenation of low-temperature tar to produce petrol the hydrogen employed is derived by overheating low-temperature coke, e.g. the coke obtained in the low-temperature carbonization process yielding the tar to be hydrogenated.  The bituminous coal is carbonized at 500-520 DEG  C., e.g. in an oven of the kind described in Specification 362,522 or 392,751, [both in Group XII], while the coke thus obtained is overheated in a second oven, e.g. of the kind described in Specification 210,068, [Class 51 (ii)].  One ton of coal is carbonized in a retort at 550 DEG  C. a yield of 1680 lb. coke, 190 lb. gas, 190 lb. liquor and 180 lb. tar being obtained.  The tar is fed to a hydrogenation vessel and 800 lb. of the coke are heated in a separate vessel to 900 DEG  C., 63 lb. of gas being evolved which are passed into the hydrogenation chamber.  The tar is hydrogenated at 450 DEG  C., 144 lb. of petrol being obtained.

Abstract: 689,295. Valves. GARDNER, L. H. Oct. 29, 1951, No. 25219/51. Class 135. A solenoid-operated valve comprises a body 10 with an inlet port 11 and a work port 12 connecting, e.g., with a ram. Both ports communicate with a bore 13 containing a seat 14 for a closure member 17, the upper end 16 of which forms the armature of a solenoid 21. The end of bore 13 remote from the solenoid is closed by a plug 36 having exhaust passages 38 which connect with port 12 when member 17 is seated and the solenoid is de-energised. A tubular extension 33 of member 17 carries a seat 39 for a ball valve 40 held from the seat, when the member 17 is seated, by a stem 37 on the plug 36. Thus when the solenoid is energised, the work port is disconnected from the exhaust passages and connected to the inlet port. A knob 32 permits of manual operation of the valve, and passages 41, 42 in the member 17 prevent any dashpot action due to fluid leaking past the member.
