Title: Oscillator fine tuning device
Inventor: GOSSARD MORRIS GLENN
IPC: H03H5/00
Filed: 1957-04-05
Abstract: 853,499. Adjusting radio apparatus. STANDARD COIL PRODUCTS CO. Inc. April 5, 1957, No. 11235/57. Class 40(5). [Also in Group XXXVI] A fine tuning device (see Group XXXVI) for use in a tuner for a very high frequency television receiver, and comprising a sprung metal strip 130 whose position with respect to an inductive loop mounted on an insulating base 126 may be varied, is adjusted by rotation of a sleeve 165 surrounding the main tuning shafts of the receiver, rotation of the sleeve 165 causing rotation of discs 180, 181 and hence the movement of pins 176, 177 within a spiral slot formed in the disc 180. As a result of the movement of the pins 176, 177, an arm 170 is moved radially with respect to the sleeve 165 and hence causes rotation of a disc 173 to which is attached a shaft having a cam shaped surface against which the metal strip 130 bears. Rotation of the sleeve 165 thus causes rotation of the disc 173 and hence movement of the strip 130 towards or away from the inductive loop on the base 126. In a modification, Fig. 11 (not shown), the base may be tilted by means of an adjustable screw to permit adjustment of the limits of variation of the position of the strip 130 with respect to the inductive loop.

Abstract: 349,229. Fluid-actuated. valves. COCKBURNS, Ltd. and MACNICOLL, D., Clydesdale Engineering Works, Cardonald, near Glasgow. April 9, 1930, No. 11250. [Class 135.] Valves controlled by pilot or relay valves.-In boiler feedwater supply regulators, the main valve 1 is formed with a piston 2 of similar diameter, feed water being supplied to a space 8 and leaking through an adjustable orifice 5, past the lower face 3 of the piston to an adjustable passage 6 leading past an auxiliary valve 16 to an exhaust, such as the feed tank. The valve 16 is controlled by the boiler water level to throttle the passage 6 and build up pressure below the piston 2, so that the main valve 1, which is constantly tending to lift under the pull of a spring 7, or the equivalent, acting through levers 20, 22, is finally lifted to admit the water to the boiler, the lift and fall of the valve being proportional to the changes of water level in the boiler. The lever 20 is connected by a link 24 to an indicating needle 25 showing the position of the main valve and may be locked in valve-closing position. The auxiliary valve 16 is controlled by a float 36 in a chamber 37 connected to the boiler water and steam, and the float is balanced by supporting it by links 50 on the ends of first-order levers 49 carrying a weighted sleeve 48. The position of the float is controlled to suit the water level condition by a screwed rod 35<1> which is slotted at 61 to engage a pin 60 on a spindle 55 rotatable by a hand-wheel 53. A sleeve 58 turning but not moving axially in the frame is internally threaded to engage the spindle 55 and is rotated by a lever 63 to adjust the pin 60 to the middle of the slot 61 after adjustment of the float level. A screw-down spindle 30 is provided for the main valve I.

In a phase shift telegraphy radio receiver a resonant circuit 24 is automatically maintained tuned to an odd, e.g. third, harmonic of the incoming carrier frequency by phase comparing its output with the incoming carrier in a phase detector 42 to derive a control voltage applied to restore correct tuning. As shown the output of harmonically tuned circuit 24 is applied through an amplifier 36 with regenerative feedback from its cathode circuit to the tuned circuit to increase the Q and after limiting at 44, 46 applied to an output circuit 56 and through a further amplifier 58, 60 to a phase detector 66, 68 receiving a limited incoming carrier frequency amplified at 62. The phase detector output across capacitor 72 is then retroactively applied to a variable capacity 32, e.g. barium titanate capacitor, or back biased semi-conductor diode, or a neon tube or reactance valve circuit, connected across the harmonically tuned circuit 24 to restore correct tuning. Output circuit 56 includes a corresponding frequency division, e.g. frequency countdown, stage so that its output is of same frequency as the incoming carrier but constant in phase. After phase shifting by 90 degrees the divider output may then be applied to a phase detector receiving directly 0 degrees, 120 degrees, 240 degrees phase changes of the incoming carrier, i.e. to produce zero output or equal positive and negative D.C. signal outputs.

Title: Improvements in wrapping machines
IPC: B65B25/14
Filed: 1938-04-19
Abstract: 495,946. Photo-electric control of wrapping-machines. CAMPBELL, S. J. April 19, 1938, No. 11726. [Class 40 (iii)] [Also in Group XVII] A wrapping-machine comprises means for moving continuously a web of wrapping- material, means for depositing articles one after another on the moving web, and a photoelectric device for controlling the deposition of each article so that it is placed in a definite position on the web, for example in correct relation to printing on the web. The web 7, Fig. 1, printed with labels 6, is drawn from a roll 8 on to a feed belt 9. The articles 10, in this case cored rolls of toilet paper, are supported on feed belts 11 and are urged into a shoot 12 from which the lowermost roll passes between a pair of spring fingers attached to a presser-foot 26. The web is formed into a channel, about the lower end of the shoot 12, by folding-wings 17, 18, which form the web into a tube the edges of which are secured by adhesive applied by a roller 19. The articles 10 are deposited on the web one at a time by the periodic descent of the presser foot 26, the time of each descent being synchronized with the travel of the web to deposit each article above an imprint 6. For this purpose, the web is printed with black marks 22, Fig. 4, which operate a photo-electric cell 24 exposed to a source of light 23. The cell is de-energized when a mark 22 passes, and through a suitable relay operates a solenoid 25 which depresses the foot 26. After the web is folded by the wings 17, 18, it is held in place by presser belts 20, Fig. 1, and fed on to another feed belt 33 moving at a slightly higher speed than the belt 9. Between the two belts, the wrapped rolls are rotated by twisting-belts 34-37 to twist the portions of wrapping-material between the articles. The twisted portion 40 is severed by knives 42, 43 actuated by solenoids 44, 45, respectively, which may be controlled by a photoelectric cell 47, the knife being operated when light directed on the cell is interrupted by the advance of the next wrapped article. The article thus separated passes on to the feed belt 37 and is moved until it engages a switch 48 which controls a solenoid 50. This solenoid moves a plunger 52 which pushes the wrapped article on to a table 53 where the twisted ends of the wrapping-material are pushed into the cores of the articles by plungers 54, 55 operated by solenoids when a switch 59 is struck by a member 58 on the plunger 52.
