Title: Video signal processing
IPC: H04N5/78
Filed: 1972-07-31
Abstract: 1402303 Television RICOH KK 31 July 1972 [31 July 1971 (2)] 35659/72 Heading H4F The bandwidth of a video signal is reduced before it is recorded on a magnetic tape by selecting, for example, every alternate line and expanding each of these selected lines to increase their duration, e.g. by sampling each elemental portion of the selected lines and reading them into a memory circuit from which they are read-out at half the rate at which they are read-in. In this particular embodiment (Figs. 13, 17, not shown) the signal samples, preferably after A-D conversion, from every alternate odd-numbered line is read into one memory circuit (e.g. a plurality of shift registers) and the signal samples from every intervening oddnumbered line is read into a second memory circuit. The expanded signals read-out of these memory circuits are combined to form a continuous video which is recorded after D-A conversion on a magnetic tape. When reproduced from the tape the signals corresponding to the alternately recorded lines are stored in respective memory circuits (e.g. shift registers after A-D conversion) from which they are read-out twice to form a standard television video signal with each line repeated (Figs. 18-22, not shown). In another embodiment (Figs. 1-5, not shown) every fourth line of a television video signal is recorded on one track of a magnetic tape after being expanded to triple their duration, e.g. by sampling, A-D conversion, storage in shift registers from which they are read-out slowly, and D-A conversion. The resulting four video signals are recorded on four tracks of a magnetic tape. Upon reproduction from the tape by four heads the signals are fed via respective A-D converters to shift register memories from which they are read-out quickly (i.e. compressed), sequentially combined into the original television video signal and displayed after D-A conversion, Figs. 6-10, not shown.

Abstract: 1505434 Directive control of communications satellite SIEMENS AG 27 Aug 1976 [28 Oct 1975] 35819/76 Heading H4D A communication satellite for receiving a radio or TV signal from a ground station in an area F, Fig. 1, and reradiating same after frequency translation on to said area, comprises a small, substantially nondirectional receiving antenna E, a relay system T and a larger, directive transmitting antenna S. To control the direction of the transmitting antenna S so that its beam covers the area-L indicates one of three equal intensity lines for the ideal placement of the beam-several transmitters St 1 , St 2 , St 3  are placed along a line L and have their frequency coded signals received by both antennae E and S. All the signals are received with equal intensity by non-directional antenna E, apart from variations due to attenuations a ti , a tj  and transmitter gains G Bi , G Bj . whilst the signals are received at different intensities by antenna S if it is not correctly aligned-variations due to a ti , a tj , G Bi , G Bi  also apply. Said variations however cancel out if the signals from each transmitter as received by S and E are subtractively compared at AV. This gives a first difference signal # i . A second such difference signal # j  is obtained from transmitter St 2 , such that a control signal # ij =# @ -# j  which is ideally zero is obtained. This is used to align beam of S.

IPC: G05B11/00
Filed: 1952-07-18
Abstract: 763,170. Electric selective signalling systems. BAKER PERKINS, Ltd. May 19, 1953 [July 18, 1952], No. 35966/54. Divided out of 763,169. Class 40 (1). [Also in Groups XXXVII and XL (b)] In apparatus for controlling the switching portions of a multi-way switch by means of a single photo-electric cell, a number of solenoids corresponding in number to all but one of the switching portions and actuating the switching member carry the anode current of a thermionic valve controlled by the photo-cell the arrangement being such that each solenoid has an optimum current so that only one at a time can override the rest to determine the switch position. As shown, the photo-cell 3, which is energized in three steps, zero, half and full illumination, controls the anode current of triode V in series with what are the windings of solenoids SOL2 and SOL3. SOL3 saturates at a lower current than SOL2 in that with full illumination of the cell SOL2 exercises an overriding effect and the switch arm moves to position 1 against the action of a spring. When the current falls the field of saturated solenoid SOL3 remains unchanged while that of SOL2 is reduced hence the switch arm takes up position II. When the light beam is entirely cut off a spring moves the arm to position III. Specifica. tions 618,157, [Group VIII], and 754,109, [Group XL (b)], are referred to.

Title: Improvements in or relating to the manufacture of goods of or containing sponge-likeor cellular rubber or the like
IPC: C08L21/00
Filed: 1933-12-27
Abstract: Sponge-like products are obtained by admixing with aqueous emulsions or dispersions of rubber or the like one or more reagents which by chemical decomposition, for example, by chemical interaction with one another or with the aqueous medium, produce one or more substances in situ which function as active coagulating agents and one or more substances which function as inflating agents, and allowing the frothy mass to set to an irreversible solid material.  Suitable reagents for this purpose are reactive metals such as zinc, aluminium, magnesium, and iron, with or without the addition of soluble non-coagulating salts such as the sulphates, chlorides, nitrates, and acetates of the alkali metals and of ammonium. Frothforming substances, for example, soaps, soapforming ingredients, or saponin may be added.  Aqueous emulsions or dispersions which may be employed are those comprising rubber, guttapercha, balata, or similar vegetable resins, occurring naturally or artificially obtained, and in the vulcanized or unvulcanized condition.  Aqueous dispersions of coagulated rubber, vulcanized rubber, synthetic rubber, or waste or reclaim rubber may also be employed, if desired, as alternatives or additions, and any of these dispersions may contain the usual compounding ingredients.  Concentrates such as are obtained by the processes described in Specifications 219,635 and 290,313, [both in Class 70], to which may be added any of the usual compounding ingredients may also be used.  Examples are given.  The Provisional Specification mentions calcium carbide and aluminium carbide as suitable reagents capable of being employed instead of reactive metals such as magnesium.

Abstract: 1277517 Sewing-machines NECCHI SpA 28 July 1970-[30 July 1969] 36476/70 Heading D1G A sewing machine for making welted pockets comprises a work plate 30 slidably mounted on a bed member 1 pneumatic means Cs and hydraulic fluid control cylinder Co for moving the work plate longitudinally of the bed, a work clamp 32 movable with the work plate with a pneumatic cylinder Ct for operating the same, a presser member 62 for holding a fabric patch on to the fabric held by the clamp 32 and folding members 43, a pneumatic cylinder Cp for operating the presser 62 and allowing the folding members 43 to operate by means of a cam, and a pair of needles 15 for sewing the patch to the fabric by a double line of stitching. In order to make a welted pocket a piece of base fabric is placed on the table 30 and held down by clamp 32. A piece of patch fabric is then placed on the work clamp and folded by members 43 against the centre presser or blade 62. The side folding members 43 follow the movement of the work plate since their pivot point is attached thereto. The blade 62 has an inverted 'T' shaped cross section and is fixed relative to the needle position. The patch fabric is folded about the presser blade 62 in the shape of an inverted T. As the work plate fabric clamp and folders move along the bed of the machine a cutter 72 which moves vertically with the needles slits the fabric between the lines of stitching. After cutting and stitching the work plate continues its movement until patch turners 112 and tab slit cutters 111 are positioned below the work piece. The tab slit cutters 111 move upwardly to make two cuts each having a 'V' shape which joins the end of the previous cut to the ends of the lines of stitching. On retraction of the cutters the tabs thus produced are folded inwardly. The control cylinder Co determines the movement of the pneumatic drive cylinder Cs by means of a rotary valve T whose rotation is caused by means of machine shaft 10. The valve T is in series with a reducing control valve R3 and a parallel circuit containing in one branch a reducing valve R2 and in the second branch a pilot valve Wo. (For Figures see next page)
