Title: Noise suppression circuits for television
IPC: H04N3/16
Filed: 1973-03-28
Abstract: 1413423 Television; automatic gain control HITACHI Ltd 28 March 1973 [31 March 1972] 14996/73 Headings H4F and H3T A noise suppression circuit for a television receiver, in which the noise suppression level, i.e. the level beyond which noise is suppressed, is raised during synchronizing pulse periods. The circuit comprises a gate circuit GT controlled by the output of a comparator circuit CP which compares the output of a reference voltage generator circuit RG with the output of a level shifting circuit LS. Circuit LS reduces the DC level of a composite input video signal by a greater amount during synchronizing pulse periods than during video information periods under control of delayed DL, amplified SA and separated SS synchronizing pulses derived for the output of the noise suppression circuit, whereas circuit RG generates a voltage equal to the peak value of the synchronizing pulses. The gate circuit GT passes the input signal to the synchronization separator circuit SS when the output of circuit RG is greater than that of circuit LS. The output from the noise suppression circuit i.e. from gate circuit GT, may be fed to the AGC circuit of the television receiver. The raising of the noise suppression level during the synchronizing pulse periods usually prevents a noise pulse located on top of a synchronizing pulse from being suppressed with consequential division of the synchronizing pulse into two pulses, and also prevents large amplitude synchronizing pulses being suppressed with similar consequential division of the horizontal flyback pulse (blanking pulse). A detailed circuit of the arrangement of Fig. 2 is described with reference to Fig. 3 (not shown).

Patent GB-461880-A (GB)
Title: Photographic shutters
IPC: G03B9/22
Filed: 1935-05-23
Abstract: 461,880. Photographic shutters. VOIGTLANDER & SOHN AKT.-GES. May 23, 1935, No. 15059. Convention date, May 24, 1934. [Class 98 (i)] In a shutter for photographic cameras, a motor or master member is adapted when running down to engage with a lever operatively connected with the retarding mechanism, and the lever is set by hand to different positions for varying the time of exposure, the frictional part of 'the retarding mechanism being disconnected whilst the lever is moved. The shutter operating mechanism is carried on an annular plate 3 and comprises a setting lever 5 for the master member 4, the arbor 6 being locked by a pawl 7 engaging a shoulder of a disc 8. The spring housing 9 is formed with a lug 10 which when released from a catch 11 is adapted to operate the shutter blades and engage the heel 14 of a pivoted lever 12 connected to the retarding mechanism. The opposite end of the lever 12 is formed with a toothed segment 15 meshing with a pinion 16 and connected through a train of gears 18, 19, 20, 21, 22, 23 to a star-wheel 24 engaged by a rocking anchor 25. The pivot bolt 26 of the star-wheel 24 and the pinion 23 are mounted on the arm of a bell-crank lever 27. Concentrically with the shutter casing is mounted a setting ring 30 formed with a cam slot 32 engaged by a pin 33 on a lever 34, the other end of which loosely abuts against a pin carried by the lever 12. Rotation of the ring 30 thus sets the position of the heel 14. The ring 30 is rotated by a pinion 38 engaging with teeth 37 on the periphery of the ring 30. A milled disc 40 is integral with the pinion and is formed in two sections 40<1> so that it is readily rotated by hand. A semicircular lever 43 lies between the sections 40<1> and projects beyond the discs 40. The free end 42 of the lever 43 engages a spring-pressed plunger 46. To the plunger is attached a pin 49 which limits the movement thereof and is also in engagement with a lever 52 which at its end is formed with a slot 53. This slot engages a pin on the lever 27 so that pressure on the lever 43 acts to rotate the bell-crank lever 27 and bring the star-wheel 24 away from the anchor 25. When the operator's finger engages the milled disc 40, the starwheel is automatically disengaged and allows the lever 12 to be moved without any great resistance. The ring 30 is formed with notches 55 which are engaged by a spring pawl 56 for arresting the ring in position. In a modification, Fig. 9, the spring catch 56 is replaced by a pivoted lever 70, normally pressed into locking engagement with the disc 30 at one end and connected at its other end to a pivoted lever 74 carrying the star-wheel 24. Specification 365,753 is referred to.

Title: Therapeutic compounds and method of preparing the same
Filed: 1951-06-25
Abstract: The invention comprises quaternary nitrogen compounds of the type of benzhydryl-dialkyl-b -hydroxyalkyl-ammonium halides and analogous compounds in which the nitrogen atom is part of a ring, and their preparation by the action of a benzhydryl halide on a dialkyl alkanolamine, a benzhydryl alkylamine on an alkylene oxide, or alkylene halohydrin and alkylating the product, or by the action of a benzhydrylamine on an alkylene oxide or halohydrin followed by alkylating and quaternating the amino N atom, or by the action of an alkanolamine with a benzhydrylhalide followed by alkylating and quaternating the N atom.  In all the reactions in which the quaternary compound is formed directly the temperature must not much exceed 50 DEG  C.  On heating in a solvent or without, the products are converted into corresponding benzhydryl - b  - tertiary - aminoalkyl ether hydrohalides.  The phenyl groups may be substituted by lower alkyl, alkoxy or halogen.  In examples, benzhydryl chloride reacts with dimethylaminoethanol, to give benzhydryl dimethyl hydroxyethyl ammonium chloride, which on heating in o-dichlorobenzene is converted into b -dimethylaminoethyl benzhydryl ether hydrochloride; dimethylaminoethanol reacts with 2- or 4-methyldiphenyl - chloromethane, 4 - chloro - diphenylchloromethane, and 4-methoxy diphenyl-chlormethane, to give the corresponding 2- or 4-substituted - benzhydryl dimethyl - b  - hydroxyethyl ammonium chlorides, which on heating are converted into the corresponding benzhydryl ethers; piperidinoethanol reacts with 2 - methyl - diphenyl - chloromethane to produce 2 - methyl - benzhydryl - b  - hydroxyethyl piperidinium chloride and, on heating, b -piperidinium chloride and, on heating, b -piperidinoethyl 2 - methylbenzhydryl ether hydrochloride; b -chloroethanol reacts with 2-methylbenzhydrylmethylamine to give 2-methylbenzhydryl b -hydroxyethyl methylamine which is quaternated with methyl chloride; 3-methylbenzhydrylamine reacts with ethylene carbonate to give the corresponding tertiary amine which is quaternated; and 3-methylbenzhydryl chloride reacts with ethanolamine, the product being quaternated as above.

Title: Method of fabrication of a wired magnetic memory plane
IPC: G11C11/04
Filed: 1971-05-14
Abstract: 1320624 Magnetic storage devices COMMISSARIAT A L'ENERGIE ATOMIQUE 14 May 1971 [8 Dec 1970] 15133/71 Addition to 1294319 Heading H3B To form a storage matrix in which parallel wires each coated with magnetic storage material are overlaid by an orthogonal folded set of parallel insulated drive wires 3, Fig. 5, the magnetic wires are positioned between parallel spacer threads or wires 6 which are bonded to the drive wires, the magnetic wires being either inserted into the channels defined by the spacer threads prior to folding the drive wires, or threaded through tunnels formed by the spacer threads and the overlying drive wires after folding and bonding is completed. The set of parallel drive wires may be formed as a printed circuit, or be formed by winding an enamelled drive wire 3, Fig. 1, over a support 2 affixed to a rotated cylinder 1, the wire enamel being coated with an adherent which is softened by passing the wire through a solvent dip 5 after cleaning in a filter 4 so that the wire adheres to the support. Alternatively, bonding may be effected by heating either in an oven or by passing current through the drive wires. The spacer threads 6 are adhesive coated and wound over the support 2 and drive wires in a similar manner, Fig. 3, the support being repositioned to give the orthogonal wiring arrangement. Spacer distribution is restricted to one half of the support, and after detachment from the cylinder 1 the drive wires are folded as shown in Fig. 5 and pressed together by plates 7, 8. Bonding is effected by combined heat and pressure, after which the spacer threads are withdrawn to provide tunnels for the magnetic wires. An alternative construction is to use a press 9, 10, Fig. 6, to loop the spacer threads, magnetic wires being dropped into the guides so formed prior to folding the drive wires. Multiple turn drive wires may be produced by winding a drive wire on to a multiplicity of supports A to D on a winding cylinder, Fig. 10 (not shown), and bonding spacer threads to support B alone, Fig. 12. The supported drive wires 3 are then folded about support B in the order A-C-D, Figs. 13a-13c (not shown), the supports A and B being removed during folding so that ultimately multitum drive wires about the spacer threads lay between supports C and D.

Filed: 1955-05-25
Abstract: 776,407. Valve oscillator circuits. TELEFONAKTIEBOLAGET L. M. ERICSSON. May 25, 1955 [May 25, 1954], No. 15163/55. Class 40(6) An oscillator comprises an amplifier having negative and positive feedback circuits the positive feedback circuit including a transformer and thermistor combination feeding its output across part of a tuned circuit coupled to the input circuit. As shown an. auto transformer 2 providing negative feedback at the cathode feeds a regenerative voltage through a thermistor 3 to a tuned grid circuit 4, 5. The transformer may have sufficient D.C. resistance to provide the bias for the valve and D.C. may either be blocked from the thermistor by means of a capacitor or the circuit constant may be chosen such that the thermistor helps to stabilize the D.C. current. The tapping point on the tuned circuit is such that the resistance of the thermistor is much greater than the apparent resistance of the tuned circuit so that the feedback voltage is proportional to the thermistor resistance. The thermistor may alternatively be connected to a capacitive tip on the tuned circuit (Fig. 3, not shown) or a piezo electric crystal may replace the tuning capacitor 5 (Fig. 4, not .shown). With alternative amplifier arrangements it may be desirable to derive the input for the amplifier from tappings on windings 2 and 4 (Fig. 2, not shown).
