Title: Packaging machines
Inventor: HARRISON THOMAS LEROY
IPC: B65B9/06
Filed: 1965-03-10
Abstract: 1,073,435. Packaging machines. PRATT MANUFACTURING CORPORATION. March 10, 1965, No. 10082/65. Heading B8C. A packaging machine comprises means for continuously feeding a flat web of sheet material and for forming it so that it has a channelshaped cross-section with upstanding-flanges, means for urging the web into a V-shape crosssection, relatively flat articles to be packaged having been placed in the channel, means for urging said flanges inwardly and downwardly over portions of the articles and for bringing opposite portions of the web into juxtaposition with the articles therebetween, and means for severing the web portions between the articles. As the web 31, Fig. 2, is fed downwardly from roller 35 it is acted upon by forming members 45 (an inclined plate) and 39 (collars on a roller 38) providing upturned flanges 43. Alternatively a roller may replace the plate. The articles 51 are placed on the web which is then gradually urged into V-shape, the flanges 43 being acted upon by fingers 52, 53, 54 and 58, Fig. 3, effecting gradual bending down over a portion of the articles. The web then passes into a final former (59), Fig. 10, including a central separation plate (61), supported to project downwardly between flanges 43. By raising or lowering the plate (61) the effective height of the former is varied to suit the particular package. Knives (74) on a rotating cylinder, Fig. 4, and oppositely disposed knifereceiving slots on an opposed cylinder periodically engage the web, being timed by the electric eye mechanism 48, Fig. 2, responsive to spots 47, to sever it between each pair of articles. The separated packages 82 pass on to a horizontal belt, being held upright by side feedbelts and delivered to a position where they are gripped between upwardly-moving belts and passed between sets of end folders, (not detailed) which simultaneously make " drugstore folds on the opposite cut ends of each package and glue the folds. The packages are then delivered to a shoot and deposited on the belt 86, Fig. 3. An alternative package, Fig. 15 has flanges (243) and flanges (244) made before the web reaches the former 45 and provided with strips of pressure-sensitive adhesive for securing in face to face relation. In a further embodiment the ends of the packages may be fin-sealed by adhesive in lieu of folding. The packages may contain a single folded article instead of two as shown.

Title: Improvements in and relating to washing machines
IPC: D06F39/08
Filed: 1942-07-22
Abstract: 562,372. Washing machines. BRITISH THOMSON-HOUSTON CO., Ltd. July 22, 1942, No. 10256. Convention date, July 24, 1941. [Class 138 (ii)] [Also in Group XXIX] The water supply to a machine for washing and centrifugally drying clothes is automatically controlled so as to fill the tub to the proper level. Thus in a machine of the type described in Specification 554,022 the mains inlet 12, Fig. 1, is connected through a valve 11 and pipe 10 to the nozzle 9 filling the tub. The valve plunger 13 is spring-pressed up to close but is depressed by a lever 15 engaging heights 25 on a timing cam 14, and having a slot 19 working on a fixed pin 20 and a shoulder 17 engaged by a latch 18 pivoted at 21 on the valve casing and pressed by a spring 23. The latch is linked at 48 to a lever 45 rocked by a pin 42 on a diaphragm 26, Fig 4, spring-controlled against the pressure in a bleeder conduit 30 connected below a constriction at 31 to the inlet pipe 10 to the tub. In the conduit 30 is interposed a constricted nozzle 34, Fig. 2, formed in a casting 32 secured to the floor 4 of the overflow chamber into which a byepass 33 leads, the outer end of which is open while the tub is filling but which is adapted to be closed by a valve 39 on a counter-balanced lever arm 36a when the overflow raises a float 36. While the tub is filling through the pipe 10 the flow through the bleeder 30, nozzle 34 and byepass 33 sucks off pressure from the diaphragm 26, but when the float rises to close valve 39, the pressure builds up above the diaphragm 26 and lowers it and its pin 42 to rock the lever 45 and latch 18 to release the lever 15 and allow the inlet valve 11 to close the main supply. To initiate the water supply the timing cam 14 is turned till one of its projections engages the outer end 16 of the lever 15. After tripping of the latch 18, the valve 11 cannot be opened until the cam 14 is turned to move the projection 25 clear of the end 16 so as to reset the latch. The injector action of the nozzle 34 renders the operation independent of variations in pressure of the water supply.

Patent GB-809580-A (GB)
Title: Time delay circuit
IPC: H03K5/14
Filed: 1957-03-29
Abstract: 809,580. Pulse delaying circuits. STANDARD TELEPHONES & CABLES Ltd. (International Telephone & Telegraph Corporation). March 29, 1957, No. 10348/57. Class 40(6). In a pulse delaying circuit the input pulse to be delayed is applied to a delay line which is open-circuited at one end and terminated at the other by a rectifier in parallel with a resistor so that with pulses of one polarity only the termination is non-reflecting an output pulse being derived after having traversed the delay line at least three times. Fig. 1 shows a circuit for delaying positive input pulses by a period equal to three times the delay of the line 1. A positive input pulse 7 applied to the grid of triode 9 causes a negative pulse 11 at the input to delay line 1, after traversing the line this causes rectifier 5 to conduct so that the line is short-circuited and a reflected pulse of positive polarity is applied back down the line 1. This reaches an open-circuited termination at the input end of the line so that it is reflected without change of polarity to the end terminated in rectifier 5 which is thus blocked so that the positive pulse meets a termination 6 equal to the characteristic impedance of the line 1. There is thus no further reflection and a positive output pulse 13 is derived from a terminal 3 delayed three times the delay period T of line 1 with respect to the input pulse 7. In a modification shown in Fig. 2 an input pulse pair 30 is applied to the grid of pentode 33 to produce the pulse pair 35, 36 at its anode which are separated by a time t1. The positive pulse 35 blocks rectifier 39 and thus encounters an impedance equal to that of line 37 so producing an output positive pulse 43 delayed by an amount equal to time T. The negative pulse 36 traverses line 37 and causes diode 39 to conduct so that there is effectively a short-circuit which causes reflection and the positive pulse travels towards the input end of line 37 encountering there an open-circuit which reflects the positive pulse without reversal of polarity. When this pulse traverses the line 37 again the diode 39 remains non- conductive and the termination is substantially equal to the characteristic impedance of line 37 so that a positive pulse 44 may be derived from output 42 without further reflections. Thus the output pulse 44 is delayed by time 3T after the corresponding positive pulse of the input signal 30 and the output pulse 43 delayed only by a time T after the corresponding negative input pulse the relative delay of pulse 44 is thus 2T more than that of the pulse 43 so that time separation of the two output pulses is equal to 2T + t1. Bias voltage 40 counteracts the potential drop in resistor 41 due to current flow in pentode 33.

Abstract: 1, 064,485. Electro physical measurement control &c. PURE OIL CO. March 12, 1964, No.10553/64. Heading G1N . A method of determining the rate of corrosion of a material in an environment comprises disposing at least two pairs of differently spaced electrodes at least one of each pair of which comprises the material in the corrosive environment, supplying selectively a D. C. potential of known value and less than about 0.03 volts to one of the pairs of electrodes, measuring the I. R. drop across a resistor in series with the path between the electrodes, and using the supplied potential and I.R. drop to determine the corrosion rate. Electrode arrangements described as suitable and claimed independently comprise two ribbon like electrodes (244) (246), Fig. 14 (not shown), of the material to be tested, mounted on a base (220) and pleated at least once (248), (250); and a plurality of parallel plate or rod electrodes (10), (12), (14), (16) Fig. 1 (not shown) which are connectable to the measuring circuit through selector switches 26, 28 so that tests may be carried out for various plate spacings to eliminate electrolyte conductivity. Further electrode arrangements described include a pair of U-shaped tubular electrodes Fig. 16 (not shown) through which a temperature regulating fluid is caused to flow; a stack of ribbon like strips insulated one from the other and at the two ends by for example a polystyrene resin or polytetrafluoroethylene, the edges only of the ribbons being exposed to the environment, Figs. 16, 17 (not shown); a rod-electrode in combination with an electrode stressed by bending Fig. 13 (not shown), in which only the stressed part is exposed to the environment, and a dual arrangement Fig. 18 (not shown) of two compartments through which the flow of corrosive fluid may be controlled in accordance with its conductivity. In the measuring circuit Fig. 3 (not shown) after calibration with a variable 200 ohm resistor (58) the cell current is indicated by the position of a potentiometer wiper (69). A number of simple alternative measuring and recording circuits are described, and change over switches are provided for reversing the direction of the current. If the cell electrodes are dissimilar then the corrosion rate is indicated as the average rate for the two materials but if one of the metals is less active in the electromotive series e. g. steel in a cell comprising electrodes of steel and zinc, then the corrosion rate of the less active material can be determined.
