Title: An improved rotary stemmer for packing
IPC: B25B27/00
Filed: 1942-05-16
Abstract: 553,128. Pipe-jointing tools. CLARK, H. May 16, 1942, No. 6668. [Class 99 (i)] [Also in Group XXVI] A tool for winding packing around condensertubes comprises a sleeve 1, which is adapted to fit within the packing-receiving space in a condenser-plate 6, and has an eccentric bore to fit over the end of the tube 7. The sleeve is adjustably secured by a bolt 3 to a shank 2 having flats 2c to facilitate its rotation. A turn of the packing is inserted in the packing-space, and it then passes through a slot 1c in the sleeve 1 and under a guide-hook 4. Rotation of the sleeve causes the packing to be wound around the tube 7, and the eccentric position of the bore causes the tube to be pressed away from the wall of the packing-space, so as to permit free feeding of the packing, which is subsequently nipped between the tube and the wall. The tool may be employed as a gauge for regulating the extent to which the tubes project from the plate 6.

Abstract: 356,132. Safety razors. JONES, A. J., 14, East 48th Street, New York, U.S.A. Feb. 28, 1930, No. 6680. Convention date, Dec. 12, 1929. Void [Published under Sect. 91 of the Acts]. [Class 30.] In a safety razor, the blade clamping members 13, 26 are reversely curved so as to bend the blade 24 to different cutting angles, yielding a coarse or a fine shave. The blade-holding head has a pivotal connection about the pin 14 with the handle 10 and may occupy any of four positions thereon, one, the normal position, Fig. 2 ; two positions with the holder inclined about the pin at 45‹ to the handle on either side thereof ; and an aligned position, Fig. 6. The holder is brought into the latter position by unscrewing the complete handle a quarter turn in the clamping plate and then pivoting it about the pin 14. This slackens the clamping members and causes the blade to have an equal cutting angle at each edge. The pivot pin 14 is carried in the bifurcated end of the handle 10 and has pivoted to it a connecting member 12 in which the blade clamping screw 20 is fixed by a pin 21. There is a friction reducing washer 12b between the connecting member and the guard plate. The connecting member has locating surfaces 15, 16 engaged by a pin 17 screwed in the hollow handle to retain the blade holder in the adjusted position. In the aligned position the handle is also secured bv the reduced end of a bladealigning pin 32 carried by the clamping plate and engaging a side recess 36 in the handle. In a modification the handle is embraced by a clip carried on the guard-plate. To prevent wrong assembly of the clamping members, one blade locating pin 32 is carried on the clamping plate and the other on the guard-plate. The clamping plate may be marked to indicate the coarse and fine cutting angles. The clamping members are hard drop forgings to resist deformation on rough handling, and the handle is longitudinally ribbed and enamelled.

Filed: 1939-03-01
Abstract: 525,829. Adjusting radio tuning elements. GENERAL ELECTRIC CO., Ltd., and JONES, F. R. March 1, 1939, No. 6701. [Class 37] [Also in Group XL] In wireless receiving sets adapted to receive long, medium and short wave bands and also television sound and picture signals, and to operate as an amplifier for gramophone record reproduction, push button mechanism is provided for selecting any one of these methods of operation and adapting the receiver accordingly, i.e., when broadcast reception only is required those parts of the receiver required for vision reception only are disconnected and viceversa. The push buttons 1-7 respectively operate to connect the receiver for the following purposes (1) long wave reception (2) medium wave reception (3) short wave reception (4) 7 metre sound (5) vision and sound signals (6) record reproduction, while operation of the button (7) switches off any part of the receiver previously energized. All the push buttons are mounted on spring-biassed shafts 12 so that on depression of the shafts rocker mechanism 16 is actuated through cam members to rotate a three-contact switch 8, adapting the receiver for television, ordinary radio reception, or gramophone reproduction, to the required position. The shafts 12 co-operate with a locking bar 18 so that on depression of any of the buttons 1-6 the button is locked in the required position and the mains switch 11 is closed. Depression of the button 7 releases the locking bar assembly and thus any of the buttons 1-6 previously depressed and also moves the switch 11 to the off position. The shafts 12 connected to buttons 1-3 extend beyond the locking bar 18 so as to contact by means of cross members 19 with a rocker bar 20 which rotates the switch 9 to adjust the receiver for reception over the long, medium or short wave band as required. The shafts connected to buttons 4, 5 are also extended so as to operate switches 10 which connect up the receiver for television sound and joint sound and vision reception. Depression of the button 6. which rotates the switch 8 so that a pick-up is connected up in circuit, also serves to actuate the latch bar 18 to release any of the buttons 1-5 previously depressed and to switch off the high frequency stages of the receiver.

Title: Luminance to chrominance crosstalk reduction in encoded colour camera
IPC: H04N9/083
Filed: 1972-02-14
Abstract: 1353416 Colour television RCA CORPORATION 14 Feb 1972 [16 Feb 1971] 6766/72 Heading H4F Luminance to chrominance crosstalk reduction for the output of a colour encoding television camera of the type which, for example, utilizes a striped spatial filter (e.g. as described in U.S.A. Specification 3,378,633) is effected by separating from the composite video output signal of the camera a range of brightness signals having a harmonic relationship with (e.g. centred at one-half) a colour carrier frequency, converting these separated signals to signals having frequencies within the colour carrier passband and combining them therewith. As shown a first colour carrier wave centred at 3À5 MHz (Fl) is separated from the camera output signal and after being amplitude detected 25 and delayed 26 is combined in adder 27 with the output of a bandpass filter 21, which separates a range of brightness signals centred at one-half the colour carrier frequency F 1 , after it has been frequency doubled 28 and amplitude detected 29. A similar crosstalk reduction is effected for a second colour carrier wave by bandpass filters 22 and 23 &c. The brightness or luminance signal Y is separated by low pass filter 18 and a portion thereof is separated by low pass filter 24 and combined with the resulting corrected chrominance signal from adders 27 and 30 to form colour difference signals at outputs 36 and 38. Frequency multiplier 28 may be replaced by an amplitude detector, a squaring circuit and a tuned circuit which passes a range of frequencies centred about the colour carrier frequency (Fig. 2, not shown).

Abstract: 799,504. Jet propulsion plant. POWER JETS (RESEARCH & DEVELOPMENT), Ltd. March 1, 1956 [March 11, 1955], No. 7194/55. Class 110 (3). The area of the air intake of a ram jet or gas turbine jet propulsion plant is varied by a vane or vanes, having a portion inclined towards one of the walls or the axis of the intake to divide the flow into a number of parallel paths, which are movable along the general path of the air flow relative to the walls of the intake or adjacent vanes to vary the spacing between the vanes or between the vanes and the walls. The ram jet or gas turbine air intake comprises a duct wall 1 which supports through a spider 6 a centre tubular vane 4. Three coaxial openended tubular vanes 5 are arranged around the vane 4 and supported therefrom by spiders 7 slidable in slots 8 in the wall of the vane. The larger spiders may be strengthened by support rings 9. The vanes 5 are movable from a retracted position in which the leading edges of the vanes lie in the plane of the orifice to the extended position shown by means of three hydraulic or pneumatic jacks. The jacks may be connected in series to co-ordinate the movement of the vanes or in parallel for independent movement of each vane. Other means such as a rack and pinion, lazy-tongs screw-threaded rod or other mechanical means may be used to move the vanes. In an alternative embodiment, the vane 4 is mounted on a telescopic tube supported on the axis of the duct. The rearward end of the vanes have flanges which abut in the extended position spiders supporting the next adjacent vane. The arrangement is such that when operating fluid is supplied to an actuating piston, the vane 4 moves forward and by means of its rearward flanges moves the next adjacent vane 5 which in turn moves the following vane 5. The invention is also described with reference to an air intake of rectangular crosssection. In one of these arrangements the vanes are arranged at a common inclination to an axial plane lying along the general direction of air flow. If a centre vane is employed, the vanes may be inclined towards the centre vane. The vanes may have a major portion parallel to the direction of air flow and only its leading portion inclined as described. The inclined portion may be curved.
