Abstract: 1,228,554. Moulding pipe junctions. SCHNEIDER & CO. 11 July, 1969 [24 July, 1968], No. 35048/69. Heading B5A. [Also in Division F2] In the moulding of a ceramic pipe junction comprising a trunk part, and a branch part oblique or perpendicular thereto, a mandrel 3 and a plunger 4 are simultaneously axially inserted from opposite ends into the trunk part of a mould 1 until respective conical and tapered ends 3a, 5 thereof are in proximity within a bat of plastic ceramic material, forced'partially at 6 into the branch part of the mould by the inclined end 5. The mandrel 3 is then advanced, simultaneously with withdrawal of the plunger 4, until a mandrel collar 36, and a mould closing disc thereabove, are aligned with the socket end of the trunk, whereafter the mandrel 3 is rotated and the axis thereof is displaced along a spiral path, Fig. (not shown), to mould the pipe trunk part with simultaneous displacement of ceramic material into the mould branch part. The mandrel 3 is then replaced by a core 9, which may be rotated during its introduction, and which is located with a recess 10 displaced 90 to 180 degrees from the branch, until a mandrel introduced axially into the branch is adjacent thereto when the recess 10 is aligned with the branch to permit displacement of the mandrel thereinto. The branch mandrel is then rotated as it is displaced along a spiral path, to mould the branch. The moulded pipe junction is then removed by opening the mould in the plane of the trunk and branch axis. The apparatus may also operate in a horizontal plane instead of the vertical plane disclosed.

Abstract: 1,230,650. Digital transmission systems; variolossers. WESTERN ELECTRIC CO. Inc. 1 Aug., 1968 [8 Aug., 1967], No. 36710/68. Headings H4P and H4R. [Also in Division G4] A signal regenerator for a 2n-phase differential phase-modulated transmission system includes a phase detector which generates n baseband signals. One signal indicates the sign of the phase shift, and the sum of the other signals indicates the magnitude of the shift. The said one signal and the sum signal pass to a variable attenuator which produces a 2n-level signal which controls a frequency modulator to provide a 2n-phase d.p.m. corresponding to the input signal. One embodiment of a phase detector, Fig. 3, for an 8-phase system comprises hybrid junctions 30-36 as shown, hybrid 30 being fed with the received d.p.m. signal. Each hybrid 33-36 feeds a respective comparator hybrid 44-47 both direct and via a single phase period delay T and phase shifter ## 1-4 , each phase shifter giving a greater shift than the previous one, as detailed in the Specification. The output of each hybrid 44-46 passes to respective diode detectors whose outputs are summed at 53-56. The sum signals are regenerated at 57-60 to give signals V 1 -V 4 , each of which may be positive or negative. Signal V 3  represents the sign of the differential phase shift, and V 1  + V 2  + V 4  represents its amplitude. The sun signal controls the conductivity of a diode bridge in the leg of a T-type attenuator, Fig. 4, which is also fed with V 3 . The output of the attenuator, is therefore an 8-level signal which causes the modulator to generate an 8-phase d.p.m. signal. An alternative embodiment of the phase detector, Fig. 5 (not shown), uses only one delay T, it being placed between hybrids 30, 32, Fig. 3, the hybrids 33-36 and 44-47 being so interconnected that hybrids 44-47 give the same outputs as in Fig. 3.

Abstract: 1,251,767. Television. TECHNICOLOR Inc. 14 May, 1970 [16 May, 1969], No. 23477/70. Heading H4F. [Also in Division G2] An electronic system for processing high definition colour television video signals to produce high definition colour motion pictures comprises a colour television camera 11, Fig. 1, scanning at 24 frames per second with 1575 non- interlaced lines per frame. Each of the red, green and blue signals are sampled at three times the maximum video frequency and converted into eight-bit digital information and recorded on a magnetic tape 20 by means of 24 magnetic heads, additional heads being provided for recording digital frame addresses for each frame and timing signals. The digital signals may be reconverted to analogue form and applied via three separate but simultaneously and synchronously operating recirculating loop memories (see later) to a colour monitor 27 for allowing monitoring of the motion picture as it is being taken, or recorded 22 to provide a black and white film for editing purposes it being only necessary to convert and record one colour. Master tapes which may be copies of the entire tape recorded by the digital recorder 20, or portions thereof, are placed on one or more incremental recorders which in turn allow any number of frames or scenes of the recorded motion picture to be selected at will together with special effects. An assembler system (editing arrangement) is associated with the incremental recorders for selecting those frames and/or scenes and their sequencies for compilation into the final master motion picture which is recorded by a master digital recorder 58. The assembler is controlled by punched paper tape 54 and a special effects generator with the aid of a recirculating loop memory system in which each of three such memories include 1575 lines of switched storage elements, the storage elements in each line corresponding to the number of horizontal picture elements in a line i.e. each element stores eight bits. Upon playback of the master digital recorder, colour correction 60 and image enhancement 61 are performed electronically before the signal is converted back into analogue form and recorded on 35 mm. continuously moving colour film e.g. using a laser beam recorder comprising three laser beams, or before it is applied through a recirculating loop memory system 64 or 65 for conversion to other television scan standards such as 525 line/30 frames per second interlaced NTSC standards and 625 line/25 frame per second interlaced PAL standards (memory system 24 referred to above effects this type of conversion also) by only selecting certain lines for digital to analogue conversion and display. The aspect ratio is also modified from the motion picture size 2À35:1 to the television 1À33:1 in this memory system. The special effects referred to above may include slow motion, stop motion, speed up, dissolves, split scenes, fades, insetting and matting in addition to the general editing. A detailed description of the above referred to standard changing is given in the Specification.

Abstract: 1301227 Radio alitmeter STANDARD TELEPHONES & CABLES Ltd 22 Jan 1971 2923/71 Heading H4D A standard F.M. radio altimeter is adapted to give a digital display of the rate of change of height of the aircraft by detecting the frequency of amplitude modulation of a selected modulation frequency harmonic component of the beat frequency signal. The frequency format of the transmitted and reflected signal are shown in Fig. 1 for a round trip time of tp, frequency deviation of #f on a base frequency f 0  and a modulation frequency fm. The beat frequency signal E(t) is a periodic function of period 2T and can be expressed as a modulation frequency harmonic component series viz: and it can be shown that a small change in height (i.e. in tp) gives a large change is An, and a large change in height gives an oscillitory change in An. The rate of change of height will thus correspond to a frequency of variation of An on the amplitude of the nth modulation frequency harmonic component; such component is thus selected from the beat frequency signal by a filter 1 having a bandwidth less than 2fm. The output of the filter for a high rate of change is shown at a Fig. 5 and for a lower rate of change at f. The output is envelope detected at 2 (b, g) and the result amplified (c, h). The minimum points are converted to pulses at 4(d, i) and the pulses used to reset and restart a digital counter 5 fed with oscillator 6 (e, j). The count in the counter before each resetting, is inverted to be proportional to the frequency of the amplitude modulation and to the rate of change of height. A digital display 8 is employed.
