Abstract: 1,228,688. Data storage. INTERNATIONAL BUSINESS MACHINES CORP. 27 Nov., 1969 [23 Dec., 1968], No. 57984/69. Heading G4C. A data processing system includes a plurality of data sources 10 each having addressable locations from which, when addressed, the data becomes available 12 periodically and its availability is signalled each time before it becomes available, a common channel 18 for transfer of data from the data sources capable of accommodating data from only one source at a time, priority selection means for determining which of the available sources shall have access to the channel and priority adjustment means for rendering more significant the priority of an available source each time it is not serviced. As disclosed, each data source 10 is a magnetic drum or disc store, a tape loop, a delay line store, a transistor bi-stable or magnetic core store, a shift register store or communication signal lines, but in each case providing the data cyclically and repetitively. The required record address for a given source 10 is inserted into registers 26, 28 after decrementing by 2 and 1 respectively at 22, 24. The address currently in reading position is specified by clock-driven (e.g. by pulses from a timing track) counter 16 and compared at 30, 32 with the register contents, equality from register 26 setting a flip-flop 34 and equality from register 28 resetting it. Flip-flop 34 supplies a "record ready" signal to channel 18, a scanner in which scans the "record ready" lines until it detects a "record ready" signal when it produces a corresponding "sample" signal ;36 to gate, at 38, the data to the channel 18 and reset the registers 26, 28. To prevent a given source required to present data to the channel from being passed over too many times, the contents of register 26 are decremented by 1 at 23 periodically, to start the "record ready" signal progressively earlier thereby effectively increasing its priority. As a modification, one decrementer can be dispensed with by providing an extra output from the counter 16.

Abstract: 1,231,682. Moulding corrugated tubing. TARKETT A.B. 9 April, 1969 [16 April, 1968], No. 18279/69. Heading B5A. In the production of corrugated plastics tubing, a plain tube issuing from extrusion nozzle 11 is engaged by pairs of mould halves 13, 14, wherein none of halves 13 or halves 14 are interconnected. In operation, pairs of mould halves 13 and 14 are brought successively into engagement with nozzle 11 by means of piston and cylinder assemblies 19 and 20 respectively (dotted line position). From thence, the newly positioned pair is moved to engage the tube and simultaneously gears 24, 25 by means of a pressure plate 23. The gears continue the movement of this pair in the downstream direction and also of the pairs already positioned around the tube. Such movement over one mould length brings the downstream pair of mould halves into engagement with the pistons of assemblies 15, 16, which pistons then withdraw the halves each to an outer run position. In this position the mould halves are moved in the upstream direction by piston and cylinder assemblies 17, 18, and the upstream pair engage the pistons of assemblies 19, 20 to complete a cycle of operations. The mould halves are supported by tracks (27, 28), Fig. 2 (not shown), over the outer runs and by a track (26) for the central run; abutments (31, 33) spring-urged together, hold the mould halves together over this run. A lower pair of gear-wheels (24<SP>1</SP>, 25<SP>1</SP>) may be provided. The tube may be forced into close contact with the mould pairs by vacuum applied thereto or by internal air pressure supplied through a conduit in the mandrel of nozzle 11.

Abstract: 1,232,404. Piezoelectric crystals. UNIVERSITY COURT OF UNIVERSITY OF GLASGOW. 27 Aug., 1969 [28 Aug., 1968], No. 41015/68. Heading H1E. A piezoelectric resonator for operation in the GHz region is formed by growing a crystal on a substrate whilst taking steps to suppress wholly or partly the piezoelectric properties of the part of the crystal nearest the substrate. In normal crystal growth, the portion of the crystal in contact with the substrate is imperfect. Furthermore, when depositing a crystal with an axis inclined to the substrate, the portion in contact with the substrate tends to have an axis normal to the substrate. The effect of the invention is to render this portion of the crystal inactive in the finally produced resonator. Suppression need only be effective in the operative frequency band and may be accomplished by (a) depositing a contaminant along with the crystal material; e.g. metallic cadmium or indium with cadmium sulphide; (b) maintaining the substrate at a temperature known to suppress wholly or partly the piezoelectric properties of the material; (c) bombarding the growing crystal with atomic particles of a particular energy.
