Abstract: 1,057,281. Printing plates. OZALID CO. Ltd., A. J. O. AXFORD, and N. C. F. HUXFORD. July 24, 1963 [April 26, 1962], No. 15915/62. Heading B6C. A process for the preparation of an offset lithographic printing plate comprises producing on a layer of hydrophilic resin carried on a support, e.g. of kraft paper, and containing a finely divided reactive pigment, an image from which prints are to be made and rendering the non-image areas of the layer hydrophilic by application to the layer of an aqueous solution of a ferrocyanide or a ferricyanide such solution reacting with the pigment. The reactive pigment may be an oxide or sulphide of cadmium, molybdenum, antimony, bismuth, lead or zinc. The image may be produced on the plate either directly by inscribing the image, e.g. by typing, writing or drawing, on the surface of the resin layer using an oleophilic medium or by providing the layer with a surface coating of lightsensitive material and using photographic methods. The aqueous solution may contain copolymeric organic acid and/or phosphoric acid. It may also contain up to 10% by weight of an organic solvent to enhance the wetting properties of the solution. Further optional additives include wetting and/or thickening agents. A typical hydrophobic resin layer may comprise an amine-formaldehyde resin and a cross-linking agent therefor.

Abstract: 968,561. Ultrasonic analysis of materials. CHESAPEAKE INSTRUMENT CORPORATION. April 27, 1962 [June 12, 1961], No. 16095/62. Heading H4D. The velocity-temperature relationship of ultra-sonic waves in a medium is utilized to determine the amount of a particular substance forming part of the medium. The invention is described in connection with the determination of the butter fat (BF) content of milk, the velocity-temperature relationship for ultrasonic waves in which is shown in Fig. 1 for various proportions of BF, " solids-not-fat " (SNF) and water (H 2 0). By measuring the velocity of two (different) temperatures T 1 , T 2 , the slope of the characteristic and hence the BF content may be determined. In Fig. 2, which shows the arrangement employed for carrying out the invention, milk at temperature T 1  (monitored by device 32) flowing through a conduit 30 passes a first velocity measuring position comprising an electro-acoustic transducer 38 and an acoustic wave reflector 40 and then passes via a heating element 34, which raises the temperature to T 2  (monitored by device 36) to a second velocity measuring position comprising an electro-acoustic transducer 42 and an acoustic wave reflector 44. The two transducers are energized via respective blocking oscillators 46, 48, both preferably operating on the same frequency (> 500 kc./s.) and so arranged that after a burst of frequency has been produced the oscillators stop until triggered by a pulse derived by reflection of the transmitted energy by the reflectors 40, 44. The repetition frequencies f, f 1  of the oscillators is then a measure of the velocity of the acoustic waves at the two positions and by supplying the two frequencies to a mixing circuit 64 and selecting the difference frequency from the mixer output a signal is derived which is proportional to the slope of one of the curves (Fig. 1) and hence to the BF content of the milk. Such signal is supplied via a device 68 which produces a steady state signal for application to an indicator 72 and for measurement of the frequency f, a similar arrangement employing the elements 52, 56 is employed. The frequency f 1  on line 62 may also be indicated by a further similar arrangement. The acoustic reflectors 40, 44 may be replaced by receiving transducers, the outputs of which are arranged to trigger the oscillators 46, 48 and instead of making the two velocity measurements on a single milk sample two separate samples may be employed.

Abstract: 822,890. Grinding. BOTTE, G. May 20, 1958 [May 29, 1957; Nov. 19, 1957], No. 16133/58. Class 60. A machine for grinding the rectilinear edge faces of glass sheets 3, Fig. 1, comprises a grinding drum 2, a movable support which, from a position wherein the middle plane 17, Fig. 2, of the glass coincides with an axial plane 16 of the grinding drum, moves the glass to one side or the other to a position which makes an angle α<SP>1</SP>, α<SP>11</SP> with axial grinding planes 161, 1611 whilst the glass is resiliently urged towards the drum, and pair of stops 4, 5, the stop 4 preventing the glass being drawn by the drum towards the direction in which the drum is rotating, and the stop 5 preventing the glass moving away from the stop 4 ; the angles #, Fig. 4, between the face 18 of each stop engaging the glass and the corresponding face 19 on the stop facing the drum are, at a maximum, the complement of the maximum angle through which the sheet 3 moves from the axial plane 16. The sheet 3 is clamped by bolts 6 between the stops 4, 5 which are in the form of laths and may be faced with a damping substance such as rubber, the lower stop 4 being secured to a rod 7 which is rotatably mounted in arms 8 and has further arms 9 secured thereto. The arms 8 are pivoted to the frame of the machine and are resiliently urged by springs, counterweights or, as shown, pneumatic piston-and-cylinder devices 20, 21 to press the glass against the drum. The arms 9 are jointed by a rod 10, which serves as a rest for the glass, and are connected by rods 11 to discs 12, one of which is driven by gearing 46 from an electric, hydraulic or oleo-pneumatic motor 45 ; the rods 11 may engage any one of a series of holes in the arms 9 and are adjustable for length so as to vary the speed or amplitude of movement of the glass sheet. The motor 45 is driven in alternate directions by the actuation of switches 26, 26<SP>1</SP> on a rod 29 by the support arm 9 ; the switches may be adjustable and more than one pair may be mounted at different angular and axial positions in the rod 29. A modification of this embodiment consists in the stops 4, 5 not participating in the oscillating movement of the support but being fixed with their faces 19 vertical. In another embodiment, the glass 3, Fig. 6, is retained by the stops 4, 5 on the arms 9 which, at one end, are pivoted to a slide 39 movable in a guide 40 and, at the other end, are connected to a pivot 33 radially movable in a crank 35 alternately rotated in opposite directions about an axis 15 coincident with the axis of the drum 2 by a crank 36 and disc 12 driven from a motor 45. In a further embodiment, the glass is retained by the stops 4, 5, Fig. 7, in the arms 9 which are moved parallel to themselves by cranks 35, 38 driven by a chain 40. The sheet may be moved to its two extreme positions to blunt the sharp edges prior to grinding the edge face flat.

Abstract: 1,076,773. Protective arrangements; automatic circuit-breakers. A. REYROLLE & CO. Ltd. July 28, 1964 [April 29, 1963], No. 16809/63. Headings H2B and H2K. A power distribution system has an auto-reclosing circuit-breaker R4A controlling the supply to a cable or line 10 having a plurality of sectionalizers 1S3, 2S2, 3S1 spaced apart in series along the cable or line, each sectionalizer having a counting mechanism arranged to open the sectionalizer during a " dead-time " of the circuit breaker after a predetermined number of fault current passages less than the number of operations of the circuit-breaker required to cause it to lock open. The mechanism of each succeeding sectionalizer beyond the first is set to open the sectionalizer after fewer passages of fault current than the one before it, and the circuit-breaker is provided with an indicator to indicate the number of times the circuit-breaker has opened so as to show which sectionalizer has opened. Fig. 1 shows a system fed from both ends through circuit-breakers R4A, R4B arranged to look out after four successive opening and closing cycles within a short period. The sectionalizers 1S3, 4S3 open after three passages of fault current, the sectionalizers 2S2, 5S2 open after two passages of fault current and the sectionalizers 3S1, 6S1 after a single passage of fault current. With this arrangement the sectionalizer 3S1 would normally be open, but in a further arrangement in which the loop is normally closed, each sectionalizer is provided with two counting mechanisms respectively responsive to supplies from opposite ends of the cable or line. Each sectionalizer has a solenoid 20 energized in the event of overload or unbalance currents to operate a pawl 26 so as to raise a rack 37 one step, Fig. 3A. The return of the rack is delayed by a dash pot 40, the positioning of which determines the number of steps the rack has to be raised before a flange 60 lifts a stirrup 56 so that it engages behind a claw 61 on the solenoid plunger 25. Then as the circuit-breaker opens causing the solenoid to be de-energized, a spring (not shown) returns the plunger 25 and through the stirrup 56 turns a latch 54 to release the tripping lever 50 of the sectionalizer.
