Abstract: 671,525. Copy-milling. MARCHANT, L. E. Oct. 23, 1950 [Nov. 3, 1949], No. 25760/50. Class 83 (iii). A tracer stylus for a copying-machine, such as a copy-milling machine operating by parallel traverses, is rapidly vibrated by an unbalanced rotating mass mounted on it, thus reducing its frictional drag on the pattern. In one form, Fig. 1, the stylus 5 is locked in a holder 3 by a collet nut 4 and a gapped ball race 12 is formed round the stylus by collars 7 and 11. Pressurefluid, preferably air, from a pipe 9 is admitted to an annular chamber 8 in the upper collar and passes down a helical groove 7c in the collar to impinge on a ball 13 and rotate it rapidly round the race 12, the air then escaping through the gap in the race. In another form, Fig. 2, an unbalanced turbine rotor 14 is rotated by air from a nozzle 18. In either form, the frequency of the vibrations can be varied by a throttle valve in the air supply and, to avoid resonance effects, the frequency should not be a multiple of the frequency at which the cutter teeth engage the blank.

Abstract: 928,045. Floor cleaning appliances. HOOVER Ltd. Aug. 4, 1959 [Aug. 8, 1958], No. 26627/59. Class 138 (1). A floor cleaning appliance comprises a combined scrubbing and water pick-up nozzle 10, a motor-fan unit mounted inside a casing 11, a liquid tank 12, a separator 13 having a suction venting lid 14 and a propelling handle 15 which carries a 3-position control handle 17. The liquid tank 12 has a valve-controlled outlet 40, the valve 41 being mounted on a leaf spring 43, one end 44 of which is bent round to contact the head 68 of the lower portion of a control rod 60, the upper portion of which is connected to the handle 17. A compression spring 69 interposed between a bracket 70 on the handle 15 and a washer 71 secured to the control rod 60 forces the control rod in an upward direction and thus maintains the valve 41 closed until the handle 17 is suitably operated. The upper portion of the control rod 60 lies within the handle 15 and has an elongated slot 65 through which passes the tail 62 of the venting lid 14, a spring detent 64 holding the lip open except when the control rod 60 is in its uppermost position. The control rod is operated by means of its upper end 55 passing through a slot 54 in the out-turned end 53 of the handle 17. Thus, in the position of the handle 17 shown in full lines in Fig. 4, the suction from the motor-fan unit is not applied to the nozzle 10 and the dispensing valve 41 is closed (the " scrubbing " position); in the uppermost of the broken line positions, suction is still not applied but the dispensing valve 41 is opened to allow cleaning liquid to pass to the floor (the " dispensing " position); and in the lowermost of the broken line positions, the dispensing valve 41 is closed and the suction is applied to cause air and dirty liquid to be sucked up (the " pickup " position). The air is removed by means of the separator 13 and the dirty liquid passed to a bag 77 inside the tank 12. The dry air is discharged through the duct 76 on to the floor where it produces some drying action. In this embodiment of the invention, the cleaning liquid is dispensed from tube 74 in front of the duct 76 where the air stream will spray it towards the nozzle 10, but in another embodiment, it is dispensed through an opening in the suction circuit to the nozzle, the opening being controlled by a valve so actuated by the control means as to be closed in at least the pick-up position. In a third embodiment, the control means is arranged to switch off the motor in the dispensing and scrubbing positions. Specifications 882,020 and 928,048 are referred to.

Abstract: 1316005 Contact printers BLU-RAY Inc 19 April 1971 [30 July 1970] 26779/71 Heading G2A A diazotype copier includes a guide, for receiving an original with a copy material in the form of a diazo-sensitized film superimposed, comprising two generally parallel wall members, one of which is a platen 23 capable of transmitting U.V. light from a source 10 and the other is an opaque member 22 part of which is cut away to form an aperture 31; complete insertion of the original and copy material, which may be aperture cards, into the guide results in the depression of a switch button 48 which closes a micro-switch 47 actuating a variable timer (49); the timer energizes a solenoid 40 which causes a pressure plate 33, 34, 35 to move in a linear direction through the aperture 31 and press the cards into uniform contact. The exposure of the film is also controlled by the timer which energizes another solenoid 46 controlling a shutter 45. The shutter 45 is rotatably mounted between the edges of two light shields 27, 28 which converge from the platen 23 towards the source 10 and during exposure is pivoted out of light interfering relationship between the source and platen 23. After exposure the pressure plate moves out of contact with the cards and the pressure of button 48 ejects them from the guide 21. The exposed film is then inserted in a developer unit comprising a chamber, defined by opposed plates 71, 72 and having a heater unit 80 and thermostat 83 mounted externally of the chamber to maintain it at a predetermined temperature. Ammonia gas is circulated through the chamber via inlet and exit ports 73, 74 by a pump (96) which reduces the pressure at the exit port relative to that of the chamber. The gas is bubbled through an ammonium hydroxide solution to obtain the required humidity. The film is prevented from being sucked against the exit port 74 by flanges 75, 76 extending the length of the chamber. In an alternative embodiment two or more exposure or developer units may be provided with a single common light source 10.

Sept. 27, 1931, No. 26783. Convention date, Sept. 27, 1930. [Class 39 (i).] The filaments of multifilament R÷ntgen-ray tubes are selectively energized automatically according to the energy impressed on the tube so that a filament giving a broader focal spot is energized when the energy rises above a certain valve. In switching over from one filament to another, break of the high-tension circuit is avoided by keeping a circuit to one filament continuously closed through a resistance. An electromagnet K in the primary or secondary circuit of the high-tension transformer E or across the primary of the filament transformer 3 controls a switch R determining which of two filaments P, W is energized, a spring Y keeping the switch against the contact S when the energy is below a certain valve. When the switch R is passing from the contact S to the contact T and touching neither, a resistance O keeps the circuit of the filament P complete. The high-tension circuit is controlled by a switch A, an autotransformer C and a variable resistance D and the low-tension circuit by a switch B and a variable inductance 4.
