Title: Improvements in photoelectric scanning
Inventor: WILLIAMS FRANCIS EDWARD
IPC: G06K7/10
Filed: 1949-02-16
Abstract: 691,465. Scanning records photo-electrically. POSTMASTER GENERAL. Feb. 15, 1950 (Feb. 16, 1949], No. 4271/49. Class 40 (iii). Marks on a record, postage stamps on envelopes &c. are detected by means of an oscillating mirror which produces an image of the mark on an aperture in a diaphragm behind which is situated a photo-cell, an alternating signal being obtained from the cell as a result of the image movement in and out of the aperture. As shown, light reflected from a column of a record card G is focused by lenses L1, L2 and mirror M which may be concave on to a row of apertures B2 behind each of which is situated a photo-cell (refs. 1 to 9). The mirror is mounted on the reed of an electromagnetic vibratory system O. Fig. 4 shows the image of a card column superimposed on apertures in the diaphragm A. If vertical column 4 is scanned, photo-cell 5 will give an alternating output. The card may then be advanced one column. Alternatively, all the spaces on the record card may be scanned simultaneously if a photo-cell and diaphragm aperture is provided for each card space. The card boundary lines may be marked in a colour to which the photocell is made insensitive, possibly by means of a filter. Specification 468,448 is referred to.

Title: Improvements in or relating to Change Speed Gearing.
Inventor: BLANC-GARIN HENRI CONRAD
IPC: F16H3/66
Filed: 1919-02-20
Abstract: 123,753. Garin, H. C. Blanc-. Feb. 20, 1918, [Convention date]. Variable-speed and reversing gearing.-Relates to epicyclic gearing for automobiles &c. capable of giving reduced variable-speeds in a forward and reverse direction, and a speed equal to that of the driving shaft. It comprises two groups of epicyclic gearing, the planet carrier of the first group being fixed to the driving shaft and that of the second group to the driven shaft. The first group reduces and reverses the motion of the driving shaft, whilst the second group, which is driven from the first group, restores the direction of motion to that of the driving shaft, and further reduces the speed. Variations of speed and direction of motion are obtained by variously holding stationary the sun-wheels of the two groups by means such as brakes. In the form shown, the planet carrier A<2> of the first group A<1> is attached to the driving shaft A, and the carrier B<2> of the second group B<1> is attached to the driven shaft B. The carrier A<2> carries a pair of planet pinions a<4>, a<5> gearing with sun-wheels g, e, a second pair of planet pinions gearing with sun-wheels c, e, and a stepped planet pinion a<2>, a<3> gearing with the sun-wheels f, e. The sunwheels c, g, f are attached respectively to brakedisks c<1>, g<1>, f<1>, and the sun-wheel e is fixed on a sleeve e<1> which carries a sun-wheel e<2> gearing with planet pinions on the carrier B<2> of the second planetary group B<1>. The group B' is similar to the group A<1>, but its members are arranged in reverse order, and various reduced direct and reversed speeds, and a direct drive, are obtained by variously holding stationary the disks g<1>, c, f<1>, i<1>, k', m<1>. Intermediate pinions may be placed between the sleeve e' and the group B<1> to obtain further differences in speed.

Title: Method of heat treating steels and other metals
IPC: C21D1/09
Filed: 1946-02-12
Abstract: In a method of heat-treating the surface of a metallic work-piece, a small zone of the surface, comprising a point or a line, is subjected to heating by an electric current from a conducting member rolling over it, which heating does not substantially raise the temperature of the remainder of the workpiece.  The rolling member may be in a disc or a roller and may have axial movement with respect to the article being treated. The heating may anneal, or, followed by quenching by a jet of cooling medium, harden the surface or may temper work previously hardened.  As an example a railway wheel which has become flattened may be annealed, turned and finally hardened. The method may also be applied to the hardening of gear teeth, rolls for rolling mills, bolts or shafts.

Title: Improvements in the Doffing Mechanism of Spinning, Twisting and like Frames.
IPC: D01H9/04
Filed: 1918-03-13
Abstract: 123,843. Boyd, T. A., Boyd, H. A., and Boyd, J. & T. March 13, 1918. D o ffi n g - arrangements; b u i l d i n g - motions.-In frames in which the builder rails and step rails if such be used are lowered clear of the spindles for doffing, a shaft 12 is employed as a lifting- shaft and a doffing- shaft, and is driven from the loose pulley by reversing - mechanism. This mechanism comprises friction gears 55, 57, Fig. 3, connected by gearing 56, 58, 59. A friction gear 51 on a shaft 49 can be moved to engage with its outer or its inner periphery one or other of the gears 55, 57. The shaft 49 is connected by bevel and worm gearing to the shaft 12. The shaft by which the motion is transmitted can be moved to disengage the worm gearing. The shaft 12 carries pulleys 13 connected by chains 9 to the sliding supports 8 for the builder rail 11. The supports 8 slide in guides mounted on brackets 10 carried by the step rail 6. The step rail 6 is carried by brackets 5, Fig. 2, carried on guide-rods 4 and supported by chains 17 and balance-weights 18. A relief chain 19 is employed connected to the pulley 13 to raise the weights 18 when it is desired to lower the step rail for doffing. During spinning, the step rails are supported upon a locking-bar 20 carrying brackets 23 engaging the brackets 5. The bar 20 can be moved endways by a treadle 25 to free the step rail for doffing. The return movement of the bar is automatic under the influence of the weight 26, when the brackets 5 are raised. When the frame is stopped for doffing, the shaft 12 is disengaged from the traverse motion and is then turned to lower the builder rails 11 which fall upon the step rail and lower it sufficiently to allow the full bobbins to be removed and empty bobbins to be placed in position. The shaft 12 is then reversed and raises the builder rail until screws thereon engage the step rail and lift it into position, when the bar 20 slides back into position to support the brackets 5. The spindles are supported against the pull of the driving-bands when the step rail is removed by fixed supports adapted to engage the back of the lower flange of the wharl above the flyer. During spinning, the shaft 12 is operated by a heart cam 32 and lever 33 connected by a chain 34 to a pulley 35 loose on the shaft 12, and normally connected thereto by a pawl 36 and ratchet 37. Movement of the rod 20 when the machine is stopped for doffing raises the pawl 36 by an incline 41 and rod 40 and frees the shaft 12.
