Abstract: 1302988 Flushing apparatus for toilet installations T GULICH 19 April 1971 [7 March 1970] 23631/71 Heading E1C [Also in Division F2] A flushing apparatus for a toilet installation comprises a chamber 116 having an outlet 117 to a toilet and an inlet 125, a valve 102 connected by a hollow rod 149 to a piston rod structure 105, 105a on which is secured a piston 104 acted on by a spring 136 to normally close the valve against a seat 115, cylinder chambers 106, 107 on opposite sides of the piston of which the latter chamber communicates with chamber 116 via apertures 119, a throttling arrangement 127 in a passage 129 connecting the chamber 106 with the outlet 117, and an auxiliary valve 109 on the end of an actuating rod 142 slidable in a bore in a guide 140 which guides the part 105 of the piston rod structure, rod 142 carrying at its upper end a push-button 151 for manual operation to open the valve 109 against the action of a spring 148. Upon such operation, pressure liquid from the inlet 125 travels through the hollow rod 149 to a space below the valve 109 and thence through valve aperture 124 and openings 139 in the part 105 into the cylinder chamber 106, causing the piston 104 to be moved downwardly by the pressure of the liquid until valve 109 is again seated, this movement opening the inlet valve 102 to uncover progressively inlet passages 125c, 125d. The valve 102 remains open so long as button 151 is held down and for a predetermined period after release of the button, owing to the throttling arrangement 127 which allows the liquid to leak from chamber 106 to the outlet.

Abstract: 260,928. Waygood-Otis, Ltd., and Blackburne, F. W. Sept. 25, 1926. Stopping on breakage of chains.-A safetydevice for excavators, inclined conveyers, &c., comprises two rotary members driven by the escalator chains provided with interengaging means which upon relative rotation of the mem- 'bers produce lateral displacement of a third member and thereby the opening of a switch in the motor circuit. The wheels 3 of the escalator chains 2 engage sprocket wheels 9, one of which is secured to the shaft 24 by a pin 43, and the other of which is secured to a disc 11 rotatable on the shaft. A disc 14 keyed to the shaft 24 has a rocking lever 25 pivoted on its periphery. The ends of the arms of this lever normally bear against a disc 12, Fig. 2, freely mounted on the shaft 24 and engaged by a spring 21. The trigger 19 of a switch 20 in the motor circuit is controlled by a pivoted arm 16 carrying an adjustable screw 15 which bears against the disc 12. During normal running a pin 29 depending from the lever 25 engages a notch 30 in the disc 11, but if one of the chains breaks, the relative rotation of the discs 11,. 14 causes the pin 29 to be forced out of the notch, thereby rocking the lever 25, Fig. 3, which forces the disc 12 to the left, Fig. 1, to effect the opening of the switch. Preferably three levers 25 are provided and three notches are formed in the disc 11. Specification 204,197 is referred to.

Title: Improved statistical quality-control system
IPC: G07C3/14
Filed: 1958-07-23
Abstract: 852,437. Registering output of machines. HRABAK, J. July 23, 1958 [July 30, 1957; July 31, 1957; Dec. 21, 1957; June 10, 1958], No. 23781/58. Class 106 (4). [Also in Groups XXIII and XXXV] Quality control apparatus, Fig. 2, comprises evaluating means S E  in which are compared numbers (R s , R rU , R rL ) predetermined statistically and numbers S, r occurring in a sample n in three predetermined categories defined e.g. by a particular dimension deviating from a desired mean #X by more or less than the standard deviation of a normal frequency distribution so that, in the notation of Fig. la (which shows such a distribution lying wholly within tolerance limits T L , T U ), if in any sample n, Z +  Z- (= r) is greater than R rU  there has been an undesirable upward shift of the mean, or if less than Rr L  an undesirable downward shift, while if Z +  + Z- (= S) is greater than R S  there has been an undesirable dispersion from the mean X. When the predetermined limits are passed retroactive control of the production machine may take place or coloured lamps may give signals to inform an operator what corrective action to apply to the machine. One embodiment, Figs. 4 and 5 (not shown), is a modification of apparatus with lamps of three colours which flash in different combinations and sequences according to the category of a gauged dimension of the workpiece. This apparatus is adapted to count the frequency of occurrence of the different colours and compare these with appropriate limits. Another embodiment, Fig. 6, uses a running sample of n and has a distributer D passing pulses to a sequence of memory units in a device M and a cancelling unit F to remove information from the first unit when information is fed to the (nr1)th so that only the most recent n workpieces produced influence the evaluator E. Suitable memory and cancelling units, Figs. 8, 10 (not shown), distributer, Fig. 9 (not shown), and comparators Figs. 11, 12 (not shown) are described using telephone-type selector switches, relays and resistances. The quality control system involves only counting and comparing, eliminating complex calculating means and may be used in the control of a centreless grinding machine or rolling mills producing sheet iron.

Title: Apparatus and method for bending elongated objects
IPC: B21D7/025
Filed: 1971-04-19
Abstract: 1344387 Angular bending COJAFEX NV 19 April 1971 [12 March 1970 8 Jan 1971] 23901/71 Heading B3E [Also in Divisions B6 and C1] An elongated beam, rod or tube 1, of metal, glass or a synthetic thermoplastic polymer, guided by means 4, 5, 7, is forced through a narrow transverse heating zone 14 and then bent by a pivoted arm 10 whose pivot 11 lies substantially in the transverse plane of the heating zone and whose relative transverse distance therefrom is variable during bending. A tube to be bent is mounted in the frame 2 and is guided, when forced by spring, hydraulic cylinder or screw-threaded means in the direction of arrow 3, by rollers 4 and 5 and a roller guide 6. The forward end of the tube is adjustably clamped to the bending arm 10 which is pivoted at 11 to a link 12 which permits movement of the pivot 11 during bending. Slots 15, 16 provide adjustment for different tube diameters and radii of bending. Alternatively the pivot 11 may be fixed and the guide frame 2 permitted to slide or pivot transversely during bending, Figs. 3-6 (not shown). Resilient means such as springs or rubber blocks may be provided to resist variation of the transverse distance, or the pivot 11 may be carried by blade springs (17, Fig. 2, not shown). Water is sprayed on the tube after passing through the heating device during the bending. Any deviation in the transverse distance, caused, e.g. by irregular tube wall thickness, may be monitored by a sensing device and used to adjust slightly the position of the heating device or of the pivot 11 longitudinally of the tube. The machine can be arranged for bending tubes, rods or bars into a helical shape by displacing during bending the centre of rotation 13 of the rockable arm 12. In another embodiment, Fig. 7, the bending arm 102 is pivoted to one end of a base bar frame 125 the other end of which is adjustably pivoted to the tube guide frame 104. At the end of the guide tube adjacent the heater 133 is attached a link mechanism 121, 128 and 129 the latter two links being pivoted to the bar frame 125. The length of the link 129 is adjustable by a turnbuckle 132 for varying the position of the pivots 101 relative to the heating zone 134. To increase the compressive force in the heated zone to counteract wall thinning, a braking force is applied to the arm by electrical or hydraulic means.

Title: Improvements in electrical means for reproducing photographs or like pictures including multicoloured pictures
IPC: G03F7/24
Filed: 1945-09-17
Abstract: 606,133. Copying by scanning. WHITE, D. D., and OSBORN, F. R. Sept. 17, 1945, No. 23992. [Class 40 (iii)] In a local-copying system the original is scanned photo-electrically and the signal current controls an electric field between a receiving surface and a projecting device arranged to scan the receiving surface in paths corresponding to those scanned on the original and to project on to said surface colouring matter of an intensity determined by the strength of the electric field. A lamp 12 is focused on to a transparency 14 mounted on a transparent glass or plastic drum 15 which is given suitable rotary and longitudinal scanning movements. The drum may instead be of metal with suitable orifices. The light beam passed by the transparency is then focussed on to a photo-electric cell 18, and the signal-modulated output is amplified and applied between a pen device 22 and a conducting drum 24 carrying the recording sheet 23 and preferably mounted on the same shaft 16 as the transmitter drum 15. The pen device comprises a fine bore tube with an insulating fibre (e.g. of glass) passing through the tube and terminating in a bead as described in Specification 606,130. The liquid on the bead is drawn to a point and disintegrated by the electric field, the intensity of the colour deposit being determined by the output voltage of the amplifier above the minimum necessary to cause disintegration. The position of the bead in relation to the nozzle may also be determined by the amplifier output in order to provide a coarse control. Contrast, density or colour control or corrections for distortions and aberrations may be effected by injecting suitable voltages into the amplifier. Scanning may be other than helical. Three colour prints may be produced from three-colour transparencies by using three scanning beams, three photoelectric cells of appropriate colour sensitivity, three electric circuits, and three colour depositing devices. Enlargements may be obtained by altering the relative speeds of the scanning and printing drums.

Abstract: 321,735. NavascuÚs, J. Aug. 21, 1928. Rotary machines; producing translatory motion of machine by current reaction with earth's field. -Propulsion is caused by cutting with a closed conducting turn the earth's magnetic flux which, by means of a body of permeability greater than unity, is caused to pass through an air gap, the conductor and magnetic body being respectively attached to the fixed and movable elements of a motor or vice versa. The action is explained i,n Fig. 7 wherein e, f and a, d represent the end members of closed conducting turns rotating about the members shown end-on at e and d so that the parallel members, shown at f and a, cut the lines of the earth's field which are concentrated in the interpolar gap of magnetic blocks A, B. The Specification contains explanatory matter to show that the reactions of the induced currents cause the system to move upwards or downwards according to the direction of rotation. Fig. 8 shows a machine in which two magnetic cylinders K, L, carrying conductors, are rotated by motors m, n, p, q in the gaps between magnetic members A, B, C mounted in a nonmagnetic framing. The ends of the conductors a, b, c, Fig. 9, are connected to two commutators e, f, the brushes of which are closed through an adjustable resistance r. The action is such that when a conductor such as c is in one of the gaps between the members B, C, its circuit is closed but that of the conductor a, b diametrically opposite is open. The members A, C have magnetic extensions r in the form of wires attached to frames G, F and I, H to concentrate the earth's flux in the gaps.
