Patent GB-585314-A (GB)
Title: Improvements in or relating to throw-off arrangements for printing and analogous machines
IPC: B41F13/24
Filed: 1945-02-20
Abstract: 585,314. Printing-machines. TIMSONS, Ltd., TIMSON, E. A., and DICKINSON, C. H. Feb. 20, 1945, No. 4245. [Class 100 (ii)] Printing-machines such as number or letter printing apparatus, or addressing-machines, are fitted with throw-off mechanism which enables the printing of numbers or to be stopped when desired and the printing operation to be resumed without marring the sequence of numbers &c. As applied to a numbering- machine bifurcated members 3, Fig. 9, are formed with arcuate cams 4 which operate rollers 5 controlling the setting of numbers in boxes 2 carried by a shaft 1, and the members 3 are movable by rods 7 to a position in which the cams 4 are concentric to the shaft 1 and so do not effect changing of numbers. The movement of the rods 7 is controlled by a shaft 3, Fig. 1, which is moved to a " trip " or " load " position by means of a " trip cam 17, or a " load " cam 16 mounted on the shaft of the numbering machine. A lever 25 is freely mounted on the shaft 13 and is arranged between the cams 16, 17 and can slide on shaft 13 by the action of a cam 33a operated by a lever 32, which is shown in Fig. 1 set in the " load " position with the lever 25 pressed to the right to bring a recess 25b on a boss of the lever into engagement with the cam 33a. In this position a roller 26 on lever 25 is actuated by the cam 16 which moves the lever counter-clockwise in Fig. 3 to a position in which it is locked by a pawl 27a engaging a notch 28a in a locking-plate 28. By means of a fixed pin 24 movement is transmitted counterclockwise to a lever 19 fixed to shaft 13 and movement of shaft 13 is transmitted to the bars 7 by means shown in Fig. 6 comprising a link 8 carrying the bars and arms 11, 12 pivoted to the link 8. To trip the numberactuating device the lever 32 is rotated half a revolution and the lever 25 is moved to the left against the action of a spring 31 and a roller 30 on the shaft of the locking-pawl 27a is actuated by the cam 17 so as to release the lever 25. This permits a spring 20 to move the lever 19 and shaft 13 clockwise, and so moves the bar 7 to the position corresponding to the concentric position of cam groove 4, so that change of the numbering-devices is stopped. In a modified form the lever 25 may be fixed axially and the cams 16, 17 made to slide.

Title: Improvements in or relating to overload released electric circuit breakers
IPC: H01H71/40
Filed: 1944-03-07
Abstract: 582,446. Automatic circuit-breakers. SHEPHERD, G. R. (Westinghouse Electric International Co.). March 7, 1944, No. 4255. [Class 38 (v) ] An automatic circuit-breaker opened at a predetermined overload by an electromagnetic device, or by a bimetal strip at a lesser overload, consists of two toggle levers 33, 35 pivoted at 37 and having on overcentre spring 49 suspended between pivot 37 and pin 51 on the handle 53 pivoted at 55, to provide a snap movement when the contacts 15, 29 are manually opened. The toggles 33, 35 are pivoted respectively at their outer ends to the contact arm 19 at point 39 and at pivot 43 to the cradle 41 pivoted at 45. When the trip mechanism operates, the spring 49 rotates the cradle 41 counter-clockwise throwing the pivot 43 to the left of the spring 49, thereby breaking the toggle 33, 35 and causing contact arm 19, pivoted at 21, to open the circuit. Contact 29 is mounted on a resilient arm 23 and connected to a flexible conductor 27 at the free end of the arm 23. The other end of the arm 23 is fixed to the arm 19 by the screw 25. The bimetal strip 57 is secured at its lower end to a bracket 59 to which the conductor 27 is also connected. A magnetic member 63, attached to the bimetal 57, insulatingly carries a latch 65 which engages the end 67 of cradle 41 when the contacts are closed. A plate 69 insulates the bimetal 57 from the member 63, the free end 85 of which acts as the armature of an electromagnet 71 supported on a non-magnetic frame 75. From the bimetal 57, a flexible connection 79 leads to the electromagnet coil 77. With an overload reaching a predetermined value, the bimetal 57 moves the latch 63 to the right to release the cradle 41. A heavy overload causes the electromagnet to attract the latch 63, also releasing the cradle 41. The legs 87 of the core 73 are shaped to afford a parallel face to the armature 85, and are placed out of the path of the armature. In a modification, Fig. 3, the latch 63 and the bimetal 57 are in series in the circuit and carry currents in opposite directions whereby electrodynamic repulsion between them trips the breaker on heavy overloads. The latch member may be mounted independently of the bimetal and biassed into the operating position by a spring, Fig. 4 (not shown).

Title: Improvements in the polishing of metal sheets and in sheet polishing machines
Inventor: FAIREST DEREK HOWARD
IPC: B24B7/12
Filed: 1954-02-15
Abstract: 755,437. Polishing metal sheets. FAIREST, Ltd., M. Feb. 14, 1955 (Feb. 15. 1954], No. 4319/54. Class 60 A method of imparting a mirrorfinish to a metal sheet comprises effecting polishing contact between the surface of the sheet and the periphery of a soft mop rotating about an axis transverse to the sheet and charged with fine polishing compound, and causing the polishing contact to progress repeatedly over the length of the sheet but in one direction only with respect tc the sheet. The sheet to be polished by mop 10 is supported on a bed 1 movable lengthwise, e.g. by hydraulic means, rollers 3 on the bed resting on rails 4 on a frame 5 pivoted on a fixed transverse axis 6 in a pedestal 7 at one end of a base 8. The mop shaft 9 is belt driven from a motor and means, e.g. hydraulic, may be provided for axially reciprocating the mop shaft. The frame 5 is supported by a screw jack 11 at each side; worm-wheels 24 on the jacks mesh with worms 23 on a crossshaft 22 driven through chain 21 by a motor 19 controlled by stops 15, 15A on the bed 1. At the end of a polishing stroke, stop 15 operates a switch arm 18 causing the motor 19 to rotate in the direction to lower the frame 5 with respect to the mop; a stop 25 on the frame 5 actuates a switch arm 26 to stop the motor 19, the frame 5 remaining lowered during the reverse motion of the bed 1. At the end of the idle reverse motion, stop 15A operates a switch arm 18A to start the motor 19 in the reverse direction so as to raise the frame until the stop 25 actuates a switch arm 26A to stop the motor. The switch arm 26A may be adjustable to stop the lifting movement of the jacks 11 when the frame 5 has been lifted to effect the desired contact with the mop, as may be determined by the diameter of the mop and the particular polishing stage in operation; alternatively the stop 25 may have provision for adjusting the position of operation of the switch 26A during the lifting movement. One or both of the stops 15, 15A may be adjustable on the bed 1 and may effect automatic reversal of the bed 1 or may be additional to such reversing stops. In a modification, Fig. 3, the movement of the frame 5 is effected by a hydraulic cylinder 31 controlled by stopactuated valves 36, 36A. The ram 32 operates a bell-crank lever 33 carrying a cross-shaft 35 supporting the screw jacks 30 which are adjustable by worms 31 on a cross-shaft for precisely determining the elevated position of the frame 5. In a further modification, Fig. 4. screw jacks 40 are supported by a cross-shaft 41 carried at each end by a lever 42 co-operating with a cam 43 or eccentric on a shaft 44 driven by a motor controlled by switch arms 45 45A. For the rough polishing and glazing stages, contact between the mop and the work may be maintained during both directions of movement of the bed; for the final stage, the stops on the bed 1 are set to effect the required lifting and lowering of the frame 5. The idle stroke may be made at higher speed.

Title: Improvements in or relating to microscopy
IPC: G02B21/14
Filed: 1951-02-22
Abstract: 710,495. Microscopes: SMITH, F. H., and BAKER of HOLBORN, Ltd., C. Feb. 21, 1952 [Feb. 22, 1951], No. 4363/51. Addition to 639,014. Class 97(1) A microscope according to the parent Specification which embodies reflecting means to reflect two distinguishable beams back through a transparent object is modified for use with opaque specularly reflecting objects by the omission of the said reflecting means, the beam combining means comprising at least one anisotropic double-reflecting member, polarizing means being provided to cause the two distinguishable beams to be differently polarized and means to bring the beams into parallel plane polarized relationship after they leave the combining means, the two beams both being reflected back through the system 'by the object or are so reflected by the object and the other by a reflector adjacent the object. As shown in Fig. 1 a beam 16 is incident upon a vertical illuminator. plate 15 and is either plane polarized thereby or by other means. The polarized beam 18 falls on a lens system comprising a birefringent doublet 12, combined with a glass doublet 13 providing correction for spherical aberration. The lens 12 is so arranged that its internal surface 33 is in the rear focal plane of the objective 11, and produces two beams 23, 24, polarized on rightangles which are focused by the objective 11 on the object 27 at spaced points. A quarter-wave plate 14 is placed in the beams so that on their return by reflection at the object their relative polarization is such that they can be combined by the lens 12 and directed upon coincident paths to produce interference effects at the interface 33 and which will be visible in the image seen in the eyepiece. When the back focal plane of objective is within its optical train the latter may include doubly refracting elements to act as beam combining means, or a Bertrand lens provided to project an image of this plane on to the beam combining means. The lens 12 may be replaced by a doubly refracting plate placed in the convergent beam between the objective 11 and the object 27 and a quarter-wave plate or other polarizing member used to effect the interchange of the plane of polarization of the two beams. The beam combining means may be a double-refracting prism, in which case the quarter-wave plate 14 is omitted. Separate dividing and combining means may be employed. In the modification shown in Fig. 2 the two beams are produced by a semi-transparent reflector 42, adjacent the object surface 27 which is illuminated by elliptically polarized light produced by the vertical illuminator 15, double-refracting lens 12 and quarter-wave plate 14. The beam 44 reflected by the surface 42 is rendered plane polarized by the plate 14 while the transmitted beam 45 passes through a quarter-wave plate 46 and is reflected back through the plates 46 and 14 to reach the lens 12 as plane-polarized so as to be capable of combination by the lens 12 with the beam 44 to produce interference effects. Specification 710,490 also is referred to.

Title: Improvements in and relating to sound-transmission, sound-recording and sound-reproducing systems
IPC: H04S1/00
Filed: 1934-02-10
Abstract: 429,054. Transmitting, recording, and reproducing music &c. BLUMLEIN, A. D., 7, Courtfield Gardens, West Ealing, London, and ELECTRIC & MUSICAL INDUSTRIES, Ltd., Blyth Road, Hayes, Middlesex. Feb. 10, 1934, No. 4501. Addition to 394,325. [Class 40 (iv)] The binaural system described in the parent Specification is modified by the conjoint use of velocity (directional) and pressure (non-directional) microphones. These microphones may be situated in juxtaposition and may be combined in one instrument as described in Specification 405,497, [Group XXXVIII], which comprises a moving strip instrument in which one half of the length of the strip constitutes a directionally sensitive element while the other half is acoustically damped to render it non-directional. Alternatively, two strips may be arranged sideby-side in a magnetic field, one being acoustically damped; the planes of the strips may be angularly adjusted, if desired, to achieve the desired binaural effect as will appear later. Such a combination has a cardioidal directional response curve and a pair of them may be used instead of the directional microphones used in the parent Specification. When different microphone groups are used for different sub-bands of the frequency range as in Specification 429,022, the present arrangements may be used for one part of the range. The microphone combination may be used as shown in Fig. 1 where a is the velocity microphone with its strip arranged along the axis of the sound field and b is the pressure microphone. Microphone a is insensitive to a sound source S1 in the centre of the field but has maximum sensitivity to sounds arriving from S2 at the side of the sound field. The outputs of the microphones are therefore similar in nature to the outputs of the two channels described with reference to Fig. 5 of the parent Specification after being subjected to the first " sum and difference " process. Suitable outputs for binaural reproduction are therefore obtained in channels d, e after subjecting the microphone outputs to a single " sum and difference process at c. A convenient arrangement for this purpose is shown in Fig. 2 where microphones a and b are connected in series across the primary of transformer f to give a summation output while the primary of a second transformer g is connected to the common microphone terminal and centre tap on f to give a differential output.
