Title: Non-reflective lens coating
IPC: G02B1/11
Filed: 1943-12-07
Abstract: 583,890. Diminishing surface reflections. VARD, Inc. Dec. 7, 1943, No. 20443. Convention date, Nov. 27, 1942. [Class 97 (i)] [Also in Group XL] A durable reflection-diminishing film on the surface of a transparent body, of substantially one-quarter wave-length thickness (or an odd multiple thereof), is composed of two layers of transparent materials, both having a refractive index substantially less than that of the body and the refractive index of the outer layer being substantially greater than that of the inner, the thickness of the outer layer being not less than one-quarter that of the film. The refractive index of the transparent body may be 1.510, that of the inner layer of the film 1.33, and that of the outer layer 1.43, the thickness of the outer layer being between one-quarter and one-third that of the whole film. In applying the film by means of the apparatus shown, the body E to be coated is supported by a rotatable disc 30 in a vacuum chamber over either of two holders 10, 11 containing respectively the coating materials of the two'layers. The pressure is then lowered by pumps 23, .24, preferably to 10<-6> mm. of mercury, during which the surfaces in the chamber are de-gassed by a high potential discharge applied by a transformer T1 connected to the supporting rod 32 of the disc 30. The de-gassing discharge results in a more tenacious film. The underlayer of the film is then evaporated on to the lower surface of the body E by heating the holder 10 by current supplied to it from a transformer T, the vapour being guided to the body by a tube 35 and prevented from depositing on the upper surface by a cover 34. The body is then positioned over the holder 11 and the upper layer similarly deposited, the desired thickness of each layer being obtained by observation of the interference colour produced. The pressure in the chamber is then raised until an electric discharge across a gap of about three inches can be produced at about 200 volts, and is then gradually lowered to between 10<-2> and 10 mm. of mercury, the voltage of the discharge increasing to about 1000. The treatment is then continued for about 30 to 45 minutes, thereby increasing the physical resistance of the film. For the underlayer of the film any of the less dense fluorides may be used, but preferably either chiolite (sodium and aluminium fluorides) or a mixture of chiolite and lithium fluoride is used. For the second layer, one of the denser fluorides, preferably magnesium fluoride, may be employed.

Title: Capacitor charge transferring arragements and circuits
IPC: H03H11/26
Filed: 1969-04-22
Abstract: 1,273,181. Capacitor storage circuits; capacitor chain delay circuits. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 22 April, 1969 [23 April, 1968], No. 20475/69. Heading H3T and H3U. [Also in Divisions G4 and H1] A change is transferred to a capacitor C 1  connected between drain and gate of a field effect transistor from a capacitor C 0  connected between source and drain by a switching voltage source connected between the gate and the adjacent electrode of capacitor C 0 . The figure shows a binary shift register or an analogue delay line operable as a filter. During the first negative half cycle of a pulse source So current flows from an input signal source V i  through a selective large resistor R 0  to correspondingly discharge a capacitor C 0 . During the next positive cycle current flows through T 1  to restore the charge on C 0  to a value equal to the voltage So less the threshold voltage of the transistor and this charge is withdrawn from an equal capacitor C 1 . During the next negative half cycle, C 0  is again discharged to the level of the signal and the charge on C 1  is transferred to C 2 . In this manner the charge is transferred progressively along the chain of capacitors. Multiphase switching may replace the two-phase shown in which case the capacitors are connected to the phases in groups. An integrated arrangement is described in which the capacitors are the enhanced gatesource capacitance of the transistors.

Title: Machine for washing laundry, dishes or the like
IPC: D06F39/02
Filed: 1969-04-22
Abstract: 1,263,944. Washing machines. PHILIPS GLOEILAMPENFABRIEKEN N.V. 22 April, 1969 [24 April, 1968], No. 20477/69. Heading DIA. [Also in Division A4] In a washing machine, for dishes or laundry, detergents and other additives are placed in containers from which they are washed out by water from a number of parallel connected branches of a conduit, each branch when filled with water under pressure emptying one container and simultaneous pressure in two branches participating in producing a flow of water to empty a further container. As shown, the washing machine has a drum 3 rotated by motor 5 and supplied with water through two parallel branches 7, 8 controlled by electromagnetic valves 9, 10 controlled by the programme control. The detergent basin 11, Fig. 1, is divided into three compartments 12, 13, 14 for pre-wash and main wash detergent and after-rinsing agent. The outlets 15, 16 of branches 7 and 8 are located in the same plane above container 14 and directed into containers 13, 12 so that, by opening valve 10, valve 9, or valves 9 and 10 compartments 12, 13 or 14 can be emptied. In a modification, Fig. 2 (not shown), branches 7, 8 are split into main branches (29), (30) and side branches (27), (28) and the water from the combination of the latter side branches empties the container (24) of rinsing agent. In another embodiment, the basin 31 is divided by partition walls 47, 48 into containers 32, 33 for pre-wash and main-wash detergents and a compartment 34 into which extends a pipe 41 connected by a hose 42 to a bottle 44 for rinse agent. The outlets 35, 36 of the side branches 37, 38 of pipes 7, 8 are so connected to pipe 41 where it has a central partition 43 that, when water flows through both outlets 35, 36, it draws rinse agent out of bottle 44 which may contain sufficient for several cycles. In the arrangement of Fig. 4 (not shown) compartments (53), (52), (54) are emptied by conduit (70), conduits (69) and (70) and conduit (69) through side branch (58) of conduit (69), chamber (61) in conduit (70) and conduit (57) by opening respectively valve (60), valves (60) and (59) and valve (59). In the arrangement of Fig. 5, the outlets of conduits 90, 89 supplied through valves 80, 79 extend into the prewash detergent compartment 73 and the wash detergent compartment 72 and side branch 78 of conduits 89, opens into rinse agent container 74 and is controlled by a pressure sensitive valve 75 operated by the pressure in the side branch 77 of conduit 90. Thus when valve 80 is opened pre-wash detergent is washed out of compartment 73, when valves 80, 79 are opened washing detergent is washed out of compartment 72 and when valve 79 is opened rinse agent is washed out of container 74. Alternatively, valve 75 may be opened when valve 80 is opened with consequent variation in the operation.

Abstract: 767,049. Combine harvesters. ALLISCHALMERS MANUFACTURING CO. July 14, 1954 [Oct. 8, 1953], No. 20572/54. Class 58. A combine harvester has a grain bin 3, Figs. 1 and 2, and an auger 11 therein which moves grain through an outlet 21 into a discharge tube 27 which is hinged, e.g. to an elbow tube 20 secured to the outlet, so that it can be swung up and down, and is provided internally with an auger 30, a rod 40 being mounted on the discharge tube and a bracket 37, with channels 39, Fig. 4, for receiving the rod and a latch pin 42 for retaibing it being secured to the bin to hold the discharge tube in a vertical position. The auger 11 is driven from an engine 8 through gearing 12. When the discharge tube is in an inclined unloading position, the auger 30 is driven from the auger 11 by enclosed gears 23 and 22. gear 23 being secured to one end of a stub shaft 24, which is square-sectioned and tapering at the other end and fits into an aperture in the end of the shaft of the auger 30. The gear 22 may be secured either to a similar stub shaft 17 fitting into a coupling 15 on the end of the shaft of the auger 11, or directly to the last-mentioned shaft. The discharge tube may be supported in the unloading position by stays or chains 51. When the discharge tube is secured in the vertical position, the hinge pin 36 can be withdrawn and the tube can be swung about the rod 40 trunnioned in the channels 39 into a horizontal position on top of the bin and secured there by slipping the shank of a bolt 49 pivoted to the tube into a notch in a plate 47 secured to the top of the bin and tightening a wing nut 50. The discharge tube is thus stowed, within the profile of the combine harvester. The conbine harvester has front traction wheels 6 and rear steering wheels 7.
