Title: Temperature Compensation of Deflection Circuits for Television Equipment
IPC: H04N3/16
Filed: 1966-05-02
Abstract: 1,157,721. Transistor sawtooth circuits. RADIO CORPORATION OF AMERICA. 2 May, 1966 [14, May 1965], No. 19315/66. Heading H3T. In a vertical deflection circuit for a television receiver comprising a transistor amplifier having feedback via a Miller capacitor (80), means (such as a thermistor 131) is provided in series with the capacitor 80 for temperature compensation. As described, transistors 90<SP>1</SP> and 60 are reciprocally coupled via emitter followers 20, 40 and resistor 100 so as to form an astable multivibrator synchronized by pulses at P 2 . The Miller capacitor 80 is charged during the forward stroke when transistor 60 is conductive via height control resistors 84, 85 and discharged during the flyback via transistor 90<SP>1</SP> and thermistor 131. Thermal stability is also improved by feeding the emitter loads 26, 46 from a higher voltage supply B+ +. A network including diode 150 prevents spurious oscillation at subharmonics of the deflection frequency. Capacitor 160‹ suppresses spurious high frequency oscillations. A double integrator 120 . . . 124 in a feedback path between the deflection coils V, V<SP>1</SP> and the base of transistor 20 provide S- shaping for flat screen cathode-ray tubes. A flyback pulse derived at the secondary of transformer 69 is integrated by the capacitance at the base of transistor 90<SP>1</SP> so as to render the circuit less sensitive to triggering by spurious signals. Resistors 110, 152 respectively control frequency and linearity. The voltage-dependent resistor 64 protects transistor 60 against peak reverse voltages. Amplitude stabilization.-The deflection amplitude is stabilized against changes in supply voltage by a constant-voltage dropping resistor 140 and against changes in temperature by a thermistor 172. Starting oscillators.-A 0.47 ohm resistor 62 ensures starting by minimizing the saturation voltage of transistor 60. Modifications.-Transistor 90<SP>1</SP> may be replaced by a blocking oscillator.

Patent GB-439648-A (GB)
Title: Improvements in the mode of and means for producing knitted fabric
IPC: D04B1/06
Filed: 1934-07-02
Abstract: 439,648. Knitting. JONES, T. H., The Aspens, Breck Hill Road, Woodthorpe, Notting- hamshire. July 2, 1934, No. 19466. [Class 74 (ii)] Knitted fabric is produced by the cooperation with a latch needle, of an auxiliary instrument, which receives an already formed stitch loop, and retains newly fed thread to permit the old loop to be passed over a loop of the new thread. In the production of locked stitches, the needle 1 is raised to clear its loop a beneath the latch 2 and over a relatively slidable picker 4, whose point is shrouded within a groove 8, formed in a swell 7 on the needle shank. A new thread b is now laid beneath the open latch and the picker is advanced to hold the latch open and enclose thread b. On retracting the needle and picker together, loop a passes over the open latch, and over thread b, forming it into a loop. The picker is then quickly moved down out of engagement with the open latch and the retraction of the needle continued. Loop a is now caught in the needle hook, whilst the newly formed loop closes the latch and is cast off the needle, being, in its turn, passed over the old loop a. The lower part of the picker may lie behind the needle stem, being cranked at 9, Fig. 2, to bring its upper part to the front. Where the needles are mounted in a bar 10, Figs. 4 and 5, the pickers are mounted in another relatively movable bar 11, which may be accommodated in a recess in the bar 10, Fig. 5, and slidably connected thereto by pins 13, engaging slots 14. The picker, or needle may carry channelled tongues 12, Fig. 4, to serve as guides. The invention may be applied to multi-latched needles. The picker may be shaped to fit within a spoon shaped tip of the latch 2. Small lateral movement may be given to the picker to facilitate engagement with the open latch. Specifications' 329,098, 330,041, [both in Class 74 (ii)], 360,998, and 380,554 are referred to.

Title: Improvements in hydraulic devices for damping oscillations for spring suspensions ofvehicles and the like
IPC: F16F9/48
Filed: 1949-07-25
Abstract: 670,452. Pressure relief valves. KATZ, M. July 25, 1949 [Aug. 5, 1948], No. 19555/49. Addition to 669,521. Class 135 [Also in Group XXXII] A hydraulic shock absorber comprises a piston 5 defining liquid chambers 7, 8 in a cylinder 1, a valve 12 for restricting flow through a piston duct 13 connecting the chambers 7, 8 a valve-loading spring 11 interposed between the valve 12 and a movable sleeve 9, control means for increasing the valve loading as the piston moves away from a normal inoperative position, comprising opposed bowlshaped members 23, 24 carried by the piston, one (24) of which is movable relative to the other for displacing the sleeve 9, a set of balls 22 between the members 23, 24 and a rod 25 of varying crosssection, rigid with the cylinder, for displacing the balls laterally, and thus moving the sleeve 9, an amount proportional to the piston stroke. The sleeve 9 is maintained in its displaced position during the return piston stroke by the action of the same hy- .draulic pressure as that which is applied to the face of the valve. In the construction shown in Fig. 1 the sleeve 9 has a flange 10, the lower annular face of which is exposed to pressure in a space 17 within the piston which is connected by a duct 19 with the space 7. A flexible disc-valve 32 controls flow between the chamber 8 and an annular reservoir space 26. For flow from the reservoir, the valve 32 lifts freely against a spring 33. For flow from the space 8, the valve 32 is depressed at its central portion to uncover one or more flats 25x on the base of the rod 25 to provide a restricted passage to the reservoir. In a modification, the rod 25 is of constant cross section, having grooves of varying depth in which the balls 22 work. In a further modification two separate valves 12 and respective loading devices are employed, one for each direction of displacement of the piston. The rod 25 is of constant cross section and has one set of grooves which act on the balls corresponding to the first valve and.a second set of grooves for the balls of the second valve. Operation. On compression from a normal inoperative position in which the cylindrical portion of the rod 25 is in engagement with the balls 22, flow takes place freely from chamber 8 to chamber 7 via ducts 16, 19, and a lightly loaded valve 14. As the tapered portion of the rod 25 engages the balls 22, the latter drive the member 24 and sleeve 9 upwardly and progressively increase the loading of the valve 12. On rebound, damping flow takes place through the valve 12 and the loading of the latter is maintained by pressure in the chamber 7 acting through the duct 19 and space 17 on the flange 10 of the sleeve 9. The annular area of the latter flange is equal to the area of the valve 12 exposed to pressure of the chamber 7.

The glass 11 may rest on a ring within the flange 13 and a rubber ring 15 may be interposed between the flange 13 and clip 16, Fig. 3, or the flanges 13 and 17 may be bent at right angles to the wall of the case 6, the glass resting on the rim 14. The dial 10 may be of sheet metal with numerals 18 and scale 30 stamped out, Fig. 2, or it may comprise a transparent layer 19 and thin metal sheet layer 20 with numerals and scale stamped out as apertures formed in depressions bounded by inclined walls 21 and the outlines may be darkened while the remainder of the dial is brightened by a daylight reflecting white or ivory coating. Alternatively, a transparent dial 10 may have such a bright coloured covering applied, e.g. by spraying using a stencil device so that the numerals and scale remain uncovered and transparent. The pointer 9 is of roof-shaped cross-section, brightly coloured except for a dark line on the ridge. Slits 24 in the flange 13 allow light from the lamps 12 reflected by the interior of the case 6 to illuminate the inclined faces of the pointer 9 and in one embodiment a reflecting ring is inserted. By day light the numerals and pointer appear dark against a bright background, while at night by the illumination of the lamps 12, they appear light against a dark background.
