Title: Method and apparatus for polymerizing monomeric material into cast polymer sheets
IPC: B29C37/00
Filed: 1970-08-10
Abstract: 1313939 Plate casting moulds ROSTERO SA 10 Aug 1970 38381/70 Heading B5A Flat smooth surfaced plates are cast from a polymerizable monomer in moulds defined between hollow heatable metal plates 9 suspended by wheels 12 from a rod 8 laterally extending across a sealed housing 1. Each plate carries on its major surfaces by means of spring clips or the like, glass plates 15, the plates being supported at their lower ends upon smooth ledges 13 carried by each metal plate and being movable away from their associated plates 9. Located between each pair of glass plates to define an upwardly open casting mould is a compressible gasket 33. In use, the distance between the metal plates and thus the width of the moulds is set by adjustable spacers 24 and the metal plates manually moved along the rod to form a series of open topped moulds into which the monomer is then cast. The plates are then firmly clamped together by screw threaded rods 46 manually rotated by means of handles 87. After this the chamber 3 within the casing is evacuated and the metal plates heated to degas the monomer and to initiate polymerization during which the cast material shrinks taking the glass plates with it. After de-gasing the chamber is returned to atmospheric pressure and the heating continued to complete the polymerization, the pressure/temperature relationship being controlled so as to prevent boiling of the cast material. Finally the moulds are unclamped the plates moved apart and the cast sheets carrying the glass plates removed. The glass plates are then removed from the cast sheets. The metal plates preferably comprise upper and lower sheets of steel or a light metal such as aluminium or an aluminium alloy bonded by an epoxy resin 9d to an external frame 9b. Internal spacers 17 divide the interior of the plate into a tortuous flowpath for a heat exchange liquid from an externally located pumping arrangement (see Figs. 3 and 7, not shown).

Title: Improvements in or relating to electric counting circuits
Inventor: WRIGHT ESMOND PHILIP GOODWIN
IPC: H03K23/76
Filed: 1956-12-18
Abstract: 833,368. Electronic counting apparatus. STANDARD TELEPHONES & CABLES Ltd; Dec. 18, 1956, No. 38558/56. Class 106 (1). [Also in Group XL (b)] An electric multi-denominational counter comprises rings of ferro-magnetic or ferroelectric cells, and equipment for scanning the cells in a particular order. The decimal counter described comprises 3 rings of magnetic storage cells formed'by a single column 21, Fig. 1, of 30 holes in one or more ferro-magnetic blocks. The holes are threaded by a common column wire connected to amplifier 21W, a common read-out wire connected to amplifier 21R and individual row wires OX ... 29X. The cells are scanned in turn each by a positive halfread pulse 1W1 followed by a negative halfwrite pulse 1W2 applied to the row wire via a 2-way transistor gate IGO ... IG29, similar pulses being applied to the column wires via 21W and gate IG33. The row wire gates are operated in the order IGO ... 9, 0, 10 ... 19, 10, 20 ... 29, 20 under control of distributers 12C, I1C. In operation, a scanning cycle is initiated for each signal " S " to be counted, applied to gate 2G9. At the termination of the signal, bi-stable trigger circuit 21F is switched to the " 1 " condition and its output 21 f1 opens column gate IG33 and, through trigger 11F, gate IG30 whereby 12C is stepped on at the end of each pulse IW2. Pulses 1WI 1 are thus applied continually to the column wire and in succession to all the row wires. Such simultaneously applied pulses will set to " 0 " that cell in the 1st ring (OX-9X) which is in the " 1 " condition, an output being obtained from 21R which sets trigger 22F to " ," Fig. 2. At the end of the following pulse 1W2, 23F is set to " 0 " via gate 2G4, thus openin writeg gate 2G1, Fig. 1. After the next step of 12C, the next pulse 1W2 will be passed to the column wire to write " 1 " in the succeeding cell in the ring, and will reset 22F to "0." At the end of each cycle of 12C, 11C is stepped via 1G32 to scan the next higher ring. If 23F remains at "0," the " 1's " read from the 2nd and 3rd rings will be re-written in the same cell. If, however, the 1st ring registered " 1 " in the " 9 " cell, 24F will be set to "1" via gate 2G6, Fig. 2, thus resetting 23F to " 1 " via 2G7 and causing a " carry " step of " 1 in the 2nd ring, carries being similarly transferred between the 2nd and 3rd rings. At the end of the scanning cycle 11F and 21F are reset to " 0 " via 1G31 and 2G10. As the cells are scanned, the output from 21R may be transferred, e.g. to a set of storage triggers, or to a magnetic drum or a shift register, as described in Specification 833,369. The scanning sequence could be restricted to those decades in which changes are to be made. In a modification (Fig: 3, not shown), three independent single column counters, for determining telegraph message serial numbers, have separate column wires, but common row scanning and control circuits. The telegraph line circuits are arranged to ensure that only one counter is operative at a time.

Filed: 1956-12-19
Abstract: 829,026. Clocks and watches. KAUFMAN, S. J. Dec. 19, 1956 [Jan. 21, 1956], No. 38772/56. Class 139 In a timepiece the alarm mechanism comprises an escape wheel 3, Fig. 1, which co-operates with the anchor 7 of the alarm hammer 5 pivoted about the arbor 6. Co-axial with the escape wheel 3 and connected thereto by pins 26, Fig. 2, are two integrally connected cams 12, 13 which cooperate respectively with the arms 9, 10 of a fork member 8 also pivoted to the spindle 6. Pivotally secured at B, Fig. 1, to the fork 8 is a rod 14 which extends through a hole in a plate 15 secured to the hammer 5. The alarm mechanism is released in known manner and the escape wheel 3 oscillates the hammer 5 which rocks the rod 14 idly about its pivot. When the cam assembly 12, 13 completes a revolution the fork member 8 is moved about its pivot and the free end of the rod 14 abuts a tooth of a pinion 17 secured to the seconds wheel 2 of the gear train so locking the alarm mechanism until the rod 14 is freed by the continued rotation of the pinion 17 when the escape wheel 3 again oscillates the hammer 5. This intermittent operation of the alarm mechanism continues until a cam 25, Fig. 1, rotated by the stop gear moves a lever 22 against the pressure of a spring 24 to effect a rocking movement of the lever 18, Fig. 2, the arm 19 of which lifts the cam assembly 12, 13 out of engagement with the arms 9, 10 of the fork member 8. The alarm mechanism then operates continuously. In a modification the cam assembly 12, 13 is axially fixed on its arbor and the lever 18, Fig. 5, moves the fork member 8 axially of its pivot to remove the arms 9, 10 from the cams 12, 13 and so allow the alarm mechanism to operate continuously.
