Filed: 1972-12-11
Abstract: 1393266 Data transmission; synchronizing SIEMENS AG 11 Dec 1972 [21 Dec 1971] 57065/72 Heading H4C Locally generated pulses at a data receiver are pulled into phase with received pulses by an error signal which is derived from the net count of a reversible counter controlled by the two sets of pulses. A pulse generator 25 in the local receiver Fig. 2, drives a divider 26 producing three outputs A, E, F, Fig. 3, where F is twice the frequency of A. The received signal B1 at 27 goes to a circuit 28 which produces pulses C4, C5 corresponding to positive and negative edges respectively of B1. These set respective bi-stables 31, 32, which are reset by the next following F pulses (F2, F4) from the divider 26, thus generating pulses K1, K2 whose duration is related to the phase difference between the received pulses B1 and the local pulses F. These pulses K1, K2 enable a gate 12 to pass the generator 25 output pulses to the counter 22, which counts up while E is 1 and down while E is 0. The polarity of the final count at t 11  thus depends on the phase difference between E and the K1, K2 pulses and hence between E and the received pulses B1. The concidence of F4 and K21 at time t 11  opens a gate 18 and enables gates 15, 16 to pass to respective inputs a, c of the divider 26 the output f of the counter 22, which is 1 for a positive net count and 0 for negative net count. The divider 26 is consequently increased or decreased in dividing ratio to reduce the phase error. A bi-stable 29 regenerates the received signal B1 in response to the now locked local signal A. Counter 22 is reset by the gate 18 output at t 11  through a delay circuit 24. In a modification (Fig. 5, not shown), a further bi-stable (33) and a second counter (23) are added, the counter (23) producing outputs (h and k) to change the divider 26 ratio only if the count exceeds upper or lower limits + N, - N. In another modification (Fig. 8, not shown), a single counter is used (30) which produces separate outputs (f, g) for opposite counts, and further outputs (h, e) when upper and lower limits ŒS are exceeded; and also has a fourth bi-stable (34). In this case the speed at which the circuit corrects any phase error between the received and local signals is proportional to the actual size of the error.

Abstract: 1,247,357. Injection moulding. BRITISH BATA SHOE CO. Ltd. 5 Dec., 1968 [5 Dec., 1967; 3 June, 1968], No. 57920/68. Heading B5A. An injection mould for footwear comprises a sole plate 4 and a split side mould 5, relatively displaceable vertically, with separate supply ducts 6, 8 for feeding plastics material of different characteristics and/or colour to the mould space provided between the parts 4, 5 and an upper 3. The ducts 6, 8 are provided by grooves located at the parting plane between the side mould parts 5a, 5b; a pair of injection ports 19a, 19b lead from the duct 6, on either side of the parting plane, to the mould space, so that when the parts 5a, 5b are separated, the material remaining in the ports 19a, 19b will be removed from the moulded sole member. Alternatively, the ports extend downwardly from the duct and lead into the sole member from below. A second sole member is moulded to the first after bring- ing the duct 8 into alignment with a duct 9 in the plate 4 and injecting material through ducts 8, 9 and injection ports 10, 11. A vent plug 15 in association with vent passages 20-22, 16 and 17 is located in the duct 9 and when injected material is fed to the duct it solidifies in the passage 20 and does not enter passages 22, so that the removal of the runner in duct 9 leaves the vent passages clear for the next cycle. Inserts 18 are located in the ports 10, 11 and ensure that on removal of the completed sole from the sole plate the material is retained in the ports, and that removal of sprue from duct 9 leaves a plug in the ports in readiness for the subsequent injection of a first sole member. Such plugs are pushed out by injection pressure when the second sole member is moulded to the first. The insert may be cylindrical with two holes 23, Fig. 8, leading from duct 9 to a conical recess 24 which connects with outlet 25. Numerous examples of inserts are shown and described; in Fig. 27 it comprises a member 72 with an inclined bore 73 leading to an injection outlet 71, with the interposition of a circular plate 75 with two perforations 78 spaced by a trough 77 formed in the plate.
