Title: Improved television scan generator
IPC: H03K4/72
Filed: 1965-07-22
Abstract: 1,119,563. Sawtooth generating circuits. FERNSEH G.m.b.H. 22 July, 1965 [22 July, 1964], No. 31372/65. Headings H3P and H3T. In a field time-base of the type in which a linearity correcting feedback voltage is generated by differentiating, amplifying and integrating the deflecting current, the input to the amplifier is applied in such a manner that spurious voltage impulses, e.g. line pulses arising during the flyback are removed. In Fig. 3, the deflecting current is differentiated by transformer 27, roughly filtered at 32-35, amplified by a valve 31 and integrated by a resistor 12 and a capacitor 23, the latter being charged and discharged to generate the input waveform for the driver valve 22. The sense of the correcting voltage 31 is such as to cut the valve 31 off during the flyback so that rectification in the valve of spurious line frequency pulses is prevented. In Fig. 4, the input waveform for the transistor driver amplifier 46-43 is generated by charging a capacitor 47 through a transistor 48 and discharging it through 50. The deflection current in deflection coils 2, 2<SP>1</SP> is differentiated by transformer 51 roughly filtered by 52-56 amplified by 57 and integrated by controlling the current through charging transistor 48. Again, the correcting voltage is in such a sense that amplifier 57 is cut-off during the flyback. Feedback through a capacitor 59 further improves the deflection linearity.

[Also in Division B6] Paper, textiles, wood, stone are coated using a transfer which comprises a base or support layer 8 of simplex or duplex paper or of a transparent plastic material, a layer 9 of starch and gum arabic or some other material which is soluble in a liquid, a layer 10 of a clear lacquer, and a layer 11 of transparent non-water soluble adhesive adapted to receive the transfer 14 from an initial support such as a sheet 13 of coated art paper. The assembly is passed between two resilient rollers the picture 14 is transferred onto the adhesive layer 11 which is preferably pressure sensitive, and the paper support 13 is washed away with a solution which may contain caustic soda. The temporary support carrying the picture 14 is then pressed against the final support which carries a layer of pressure sensitive adhesive or other adhesive, e.g. a heat sensitive glue. The picture 14 is thus transferred to the final support and the layer 8 is washed away if it is paper. If the layer is of a plastics material it may serve as a protective shield for the picture or may carry a layer of adhesive on its lower surface or secure the picture to a plate instead of the said final support. The temporary support assembly may be protected against humidity, etc. by a film 12 of a plastics material. The lacquer and adhesive forming the layers 10 and 11 may be pre-mixed and applied to the layer 9 in a single layer. The layer 9 may have a silicone base.

Title: Toilet and waste storage system
IPC: E03D11/11
Filed: 1972-07-05
Abstract: 1381628 Sanitary closets GENERAL AMERICAN TRANSPORTATION CORP 5 July 1972 [20 July - 1971] 31503/72 Heading E1C A sanitary closet and waste disposal system, suitable for a marine vessel, e.g. a tug boat, comprises a closet bowl 12 (Fig. 2), the outlet 20 of which is normally closed by a gate valve 21 which consists of a horizontal plate (Fig. 4) pivoted about a vertical axis, a tank 55 which receives waste and flushing- water from a chamber 40 (Fig. 1) below the gate valve upon operation of a transfer means, which is preferably a pump 42, but may be a motorised valve (57, Fig. 6, not shown) where the tank 55 is arranged beneath the closet, and a flushing arrangement operable in conjunction with the slide valve and consisting of a rotary reversing valve 14' which alternately supplies water from a supply 80 to opposite ends of a cylinder 90 containing a floating piston 91 so that two increments of flushing water are delivered to the bowl when the valve rotor 15 is rotated first in one and then in the other direction. Operation is effected by depressing a pedal 13 which is mechanically coupled to a pedal 14 in such a way that pedal 14 moves down with pedal 13 but can be operated independently for the addition of flushing water to the bowl whilst maintaining the gate valve 21 closed. Pedal 14 is mechanically linked to the rotor 15 of valve 14' by a link 70 and a lever arm (72, Fig. 5, not shown) secured to a shaft 73 secured to an extension (74) of the rotor 15. Pedal 13 is connected by a link 32 to a pin 23 on boss 23A of the gate valve 21 and is also connected by a rod 102 to a microswitch 1MSW which controls the motor MTR-1 of the pump 42 or motorised valve in the bottom of chamber 40. The tank 55 is equipped with a vent pipe 56 and electric heaters 1H, 2H, 3H, 4H which, when the level of waste and flushing water in the tank has reached level-sensing switch LSP-2, are energised to evaporate water until the level has dropped a predetermined amount. This process is repeated and, as the level of solids in the tank rises, temperature-sensing devices 4TCS, 3TCS, 2TCS, 1TCS are actuated in turn as a result of a rise in temperature at successively higher levels caused by the reduced heat transfer from the heaters in the presence of the solids, such actuation in each case preventing energisation of the respective heater 4H, 3H, 2H or 1H. Finally, when all the heaters are thus switched off, further flushing of waste and water into the tank causing the level to rise to near the top of the tank where a second level-sensing switch LSP-1 is positioned, operation of this switch causing the circuit to motor MTR-1 to be broken or an alarm to sound. Preferably an alarm is operated prior to this, e.g. when only one heater remains operative.

Title: Improvements in collapsing taper-thread taps
IPC: B23G5/14
Filed: 1930-10-21
Abstract: 356,014. Taps. JACKSON, L. MELLERSH-, 28, Southampton Buildings, London.-(Geometric Tool Co. ; Blake Street, New Haven, Connecticut, U.S.A.) Oct. 21, 1930, No. 31598. [Class 83 (iii).] In a collapsing taper-threading screw tap the chasers 20 are adjustable in radial slots 23 in the body 15 by means of a wedge core 17 having interlocking grooved projections 18. A cap 24, secured by screws to the body, confines the chasers. Axial movement is given to the core 17 by means of a parallel-sided inclined slot 32 therein cooperating with a similar projection 35 on an arcuate dog 36, Figs. 3 and 7, transversely slidable in a slot 37 in an axially slidable sleeve 26. Springs 39 normally maintain the dog in its outer position. An outer sleeve 27 slidable on the sleeve 26 has a wedge 42 adjustably secured thereto by a screw 45, the wedge being located in slots 43, 44 in the sleeves and engaging under the dog 36. Springs 47, Fig. 6, located in axial recesses 48 in the sleeve 26 abut against stops 49 in the body 15 to maintain the sleeve normally against an adjustable stopring 29 screwed at 31 on the body. In operation, with the tap in the condition shown in Fig. 3, the tap and work are given relative axial feed, the chasers cutting a parallel thread until an annular disc 51, adjustably attached to the sleeve 27 by axially arranged fingers 53, Fig. 7, meets the work, whereupon the wedge 42 is moved relatively to the body and sleeve 26, causing the dog 36 to be moved radially inwards and thus displacing the core 17 to gradually retract the chasers and cut a tapered thread. When the lower edge 66 of the dog passes the edge 28 of the ring 29 the springs 47 act to draw the sleeve 26, dog 36 and core 17 rapidly rearwards into the interior of the ring, thus collapsing the tap. To re-set the tap, a hand-lever 57, pivoted at 58 in the sleeve 27 and having a ball end 63 located in a recess 69 in the body 15, is rocked forwardly to the position shown in Fig. 3, first causing the front of the sleeve 27 to engage a flange 67 on the sleeve 26 and then drawing forward the sleeve &c. until the dog 36 is withdrawn from the ring 29, whereupon the springs 39 return the dog to the position shown. A spherical portion 59 on the lever rocks in an opening 60 in the sleeve 27 to exclude cuttings. Instead of controlling the tap by means of the disc 51 the handle 57 may be used or a yoke on the machine may engage an annular groove 68 in the sleeve 27.

Abstract: 898,556. Colour television; light modulating. GENERAL ELECTRIC CO. Oct. 3, 1958 [Oct. 7, 1957], No. 31628/58. Class 40(3). Relates to a colour television image projection system 36, 38, 40, 42 incorporating a light-modulating cathode-ray tube 4 having a deformable screen 3 which is controlled by signals applied to auxiliary line deflection plates 7 and 8 so as to function as a phasetype diffraction grating. In accordance with the invention, two superposed gratings are produced, the first selecting red light and being produced by a fixed frequency oscillator 17 of 14 mc/s. whose output is modulated in amplitude in valve 13 by the red video signal and the second selecting a variable colour in the blue-to-green range and being produced by a variable frequency oscillator 27 whose frequency is controlled by a reactance stage 33 in accordance with the logarithm of the ratio of the blue and green video signals and whose amplitude is modulated in value 25 by the sum of the blue and green signals. The logarithm of the ratio of the signals is obtained by deriving their individual logarithms in stages 28 and 29 and subtracting the logarithms in network 30, 31. The mean frequency of oscillator 27, i.e. the frequency produced when the blue and green signals are equal is 17 mc/s. corresponding to the selection of a wavelength of 4930 Angstroms. The blue wavelength is 4450 Angstroms and the green wavelength 5250 Angstroms. As an alternative, the control signals may be applied to modulate the intensity of the cathode-ray tube beam.
