Title: Digitized video data recording and reproducing apparatus
IPC: H04N9/808
Filed: 1981-04-16
Abstract: A signal processing circuit divides a digitized video signal of each horizontal scan interval into a plurality of data blocks D1 to D8, and a signal distributing circuit distributes the data blocks D1 to D8 within each horizontal scan interval between rotary magnetic heads in a helical scan VTR. For each horizontal interval, heads GA, GB, GC, GD (Figure 8 not shown) simultaneously record blocks D1, D3, D2, D4 respectively then blocks D5, D7, D6, D8 respectively. The heads are stacked, together with an audio head AH, with a slight circumferential stagger and delay circuits may be used so that the ends of the tracks are effectively aligned in the track width direction or staggered in the track length direction each field being recorded as a set of four digital, video tracks and one digital audio track (Figures 9, 11, not shown). Each data block D1 to D8 includes a sync signal, track identification and address signals and block parity data (Figure 4H). In the video recording circuits, Figure 2 (not shown), an interface (11) halves the data rate and multiplexes the data blocked to an AB channel and a CD channel. Each such channel has a time base compression circuit (12), to make room for error codes, an error correcting encoder (13), and a recording processor (14) which converts from 8 to 10 - bits per sample and feeds record amplifiers for two heads (GA and GB, or GC and GD). In the audio recording circuits, (Figure 6 not shown), 16 analog signals are converted to digital form then multiplexed onto one audio recording channel which includes a time compressor (75), and an error correcting encoder (76). On reproduction, an analyzer ANA indicates the number of data blocks having errors on a monitor 6, (Figures 1, 10 not shown). <IMAGE>

Title: Improvements in or relating to covering techniques
Inventor: READMAN IAN WILLIAM
IPC: B29C63/04
Filed: 1981-10-07
Abstract: In order to accommodate excess material at corners or curved regions when covering a three dimensional piece of base material with a skin of flexible sheet material, one or more slots are formed in the base into which the excess sheet material is tucked. This results in a relatively smooth final external surface, with the base covered with a uniform thickness of sheet material. A bonding material, such as a PVA adhesive, may be applied to the base and covering material to form a positive bond therebetween, also resulting in strengthening and rigidfying of the resulting structure. The technique may be used in the production from relatively cheap, plain base material of articles such as boxes and other containers having an attractive appearance and great structural strength.

Title: Ultrasonic testing
IPC: G01N29/06
Filed: 1980-10-21
Abstract: In order to avoid the necessity for repeated re-calibrations of an ultrasonic testing instrument due to changing dimensions of its electronic components, as well as due to different characteristics of the testing head 316, the material of the test object etc., it is provided that the characteristic data are entered via a keyboard 313 and corresponding digital values are stored in memory 34,35. A microprocessor 31 then sends out sequences of ultrasonic pulses of regularly varying rise/fall times and correlates the measured times with a table that permits matching the closest value to the selected data. During actual operation, the traversing time of the sawtooth wave which controls the horizontal beam deflection on the CRT is compared digitally with a calculated time and a suitable correction signal is applied to a current source which modifies the charging current of timing capacitors so as to match the correct sawtooth traversing time. Additional circuitry 311 provides for on-screen display of the position and dimensions of a detection window, textual information and other data. <IMAGE>
