Abstract: 597,273. Printing-machines. HOE & CO., Ltd., R., CRABTREE, J. O.,and QUICK, C. G. June 25, 1945, No. 16159. [Class 100 (i)] [Also in Group VIII] Cutting and folding apparatus.-In a rotary printing-machine, cutting apparatus is provided for trimming three edges of a printed product after it leaves the folding mechanism and as it passes to the delivery mechanism. The products may be formed from a printed web or webs W folded longitudinally by a former, cut into products by cutting cylinders 3, 4, and subsequently cross-folded by folding cylinders 4, 17. After leaving the folding-off rollers of the cylinder 17, the product has its side edges trimmed by slitters 14 on cylinders 13 and its rear edge trimmed by cutters 16, preferably helical, on cylinders 15. The trimmings at the cylinders 13 are either stripped from the cylinders or taken off by pins 19, and pass to a suction duct 21 which may extend close to the product to render the use of pins unnecessary. One of the cylinders 15 is provided with an opening 24 connected through its axis 22 to the duct 21 so as to draw off the rear-edge trimming, or alternatively pins may be employed on the cylinder. The trimmings may be cut up as they pass to the duct. Specification 544,183 is referred to.

Title: Line narrowing gyromagnetic apparatus
IPC: G01R33/30
Filed: 1955-06-06
Abstract: 789,238. Turbines. BLOCH, F. June 6, 1955 [June 18, 1954], No. 16233/55. Class 110 (3). [Also in Group XXXVI] The Specification describes apparatus for rotating a sample to be analysed in a magnetic field. In a first embodiment, Figs. 3-4, a rod 17 containing the gyromagnetic sample 18 is rotatable within a tube 21 surrounded by resonance voltage pick-up coil 2. The rod 17 and thus sample 18 spin rapidly when air jet 20 is directed against turbine 19 secured to top of rod 17. The rod 17 is in two sections and the sample 18 occupies a spherical-shaped cavity formed by the junction of the two sections. A second embodiment utilizes a rotatable rod 25 with sample similarly at 18 and having a coneshaped upper end supported in a conical recess in coil former 26 which supports pick-up coil 2. Air streams through holes 27 in coil former 26 and strikes the indents of the conical surface of rod 25 so as to cause both a rotational and lifting motion of rod 25. The lifting motion greatly reduces bearing friction. In another embodiment, Fig. 6, a turbine-driven agitator 31 stirs up the liquid sample 28 and thus produces the desired motion of the nuclei.

Title: Motor starting relay
IPC: H01H50/28
Filed: 1961-05-08
Abstract: 913,728. Electromagnet relays. RANCO Inc. May 8, 1961 [June 15, 1960], No. 16577/61. Class 38 (5). The effective leverage of a bow-spring engaging an armature of a relay close to its pivot and biasing said armature away from a solenoid, is reduced when the armature moves to actuate a switch mechanism on being attracted by the said solenoid. A contact-arm 21 is flexed so as to separate moving and fixed contacts 22, 14 respectively, by the movement of a relay armature 24 the end portion 29 of which has a plastic bumper 30 possibly retaining graphite or some anti-friction material. The armature has a portion reduced in width to form two shoulders 26 which engage in V- bearings 28 formed in a rearwardly projecting portion of a bracket 25 having a central opening through which the reduced armature portion projects. A flat bow-spring 32, the lower end of which is located in a recess 33 formed in a tongue 34 of an L-shaped frame 18, and the upper which is in an armature recess 35, biases the armature into its raised position so that it engages a stop 31. The distance between the walls of the recesses 33 and 35 is such as to maintain the spring 32 bowed and its ends to the left end of recess 33 and the right recess 35 respectively, when the spring leverage biasing the armature is proportional to a length shown as f. When the armature is brought into engagement with a solenoid 40, the spring leverage is reduced due to a reduction in the perpendicular distance of the armature pivot 28 to the line of action of the force produced by the spring, to a valve proportional to f<SP>1</SP>, and hence the armature biasing force is reduced by a value proportional to f-f<SP>1</SP>. The solenoid 40 is connected across a motor starter winding, not shown, so as to respond to the voltage across it, when the then reduced armature biasing force ensures that the relay armature remains actuated during the running condition of the motor, and thus keep interrupted a starter winding circuit which is series connected with the contacts 22 14. The action of member 30 on the contact arm 21 is such as to impart a peeling action to the contact 22, thus tending to break possible contact welds.

Abstract: 118,743. Waddell, P. H. Nov. 14, 1917. Washing and like tanks.-A basin for use in washing photographic prints &c. is provided with a number of water-inlet pipes leading from a multiple-way cock, the plug of which is automatically rotated in such a manner that water is discharged successively through the various inlet pipes into different parts of the basin. In the arrangement Shown in Figs. 2 and 3, water is led to a cock 12 by a main inlet pipe 1 having a branch 2 which supplies water to a tank 4 provided with a siphon discharge pipe 6. As the tank 4 fills, a float 7 rises and causes a trigger 22 to act on spokes 21 so as to turn the plug 11 of the cock 12. Water is thus discharged successively through pipes 13 - - 16 having suitably-directed outlet nozzles arranged in pockets 24, 28 communicating with the interior of the basin 5 through holes in the side walls. The basin 5 is emptied by a pipe 31 fitted at its highest part with a cock 32, which enables the pipe 31 to be used either as a siphon discharge pipe or as an overflow pipe. The basin 5 is provided with smooth internal ribs 34 and with a perforated plate 27 arranged to prevent the prints &c. from blocking the pipe 31. In a modification, Figs. 5 and 6, the plug 40 of a cock 41 is rotated by a water-wheel 39 arranged adjacent a nozzle 38 at the end of a branch pipe 37. A second branch pipe 45. formed with a nozzle 47 and with perforations 46, discharges water directly into the basin 44. The cock 41 allows water to pass alternately to discharge-pipes 42, 43.

Abstract: 685,572. Control of A.C. motors. ENGLISH ELECTRIC CO., Ltd. June 29, 1951 [July 5, 1950] No. 16746/50. Class 38 (iii) Relates to loom drives wherein a three-phase squirrel cage motor is coupled to the machine without the intermediary of any readily disengageable clutch. When the loom handle 8 is in the "off" position a circuit is completed through isolator 3, stop-button 6, and one set of contacts of a changeover switch 9 (directly coupled to the loom handle), to the coil of an auxiliary relay 7. Contacts 7a then close to complete a maintaining circuit for the relay 7 independent of the switch 9, whilst contacts 7b prepare a circuit for the coil of a main contactor 4. Movement of the handle to the "on" position actuates the switch 9 to close the main contactor and start the motor. If the power supply fails with the handle in the "on" position, both the relay 7 and the contactor 4 will be de-energised, and the machine will not re-start when the supply is restored unless the loom handle is restored to the "off" position. Manual movement of the loom handle to the "off" position de-energises the contactor 4 but the relay 7 is maintained closed provided that switches 3, 6, are not actuated and there is no power failure.
