Filed: 1932-08-05
Abstract: 407,955. Controlling tractors. HILL, W. L., 43, Preston Road, Wembley Park, Middlesex. Aug. 5, 1932, No. 22052. [Classes 79 (ii) and 79 (v).] In an agricultural endless-track tractor the steering lever is provided with an enginethrottle control, so that the driver can steer the tractor and control the engine by one hand. Thus the driver has the other hand free for lifting the implement when turning at the end of a furrow. In the construction shown, a steering hand lever 10 is fixed to a casting 11 having trunnions 12 in a fixed bracket 13. A press button 24 at the top of the lever is fixed to a rod 23 which slides within the lever, is pressed upwards by a spring 26 and is pivoted to a lever 28 connected by Bowden mechanism to the throttle. The throttle is controlled normally by the usual means (not shown) independently of the button 24, but when the button is pressed the throttle is closed to a pre-determined extent. The lever part 12 has a lug 19 carrying an adjustable screw 20 adapted to engage a spring-loaded plunger 21 which may actuate a steering brake, the part 12 being also connected by a rod 15 to a similar rocking member 17 also adapted to actuate a plunger, so that when the lever 10 is rocked one or other of the plungers is depressed and the tractor is steered to one side or the other. The steering mechanism may be that described in Specification 407,960.

Filed: 1947-08-08
Abstract: 639,267. Lathes. BARKER, R. V. Aug. 8, 1947, No. 22092. [Class 83 (iii)] A lathe has a headstock rotatable about a vertical axis relatively to the frame on which the tool saddle moves so that the axis of the rotating workpiece may be at any desired angle to the line of movement of the saddle. The latter comprises base parts 1 and 2, of the same height and machined flat, on to which are bolted head and tail brackets 3, 4, respectively. Horizontal bores are provided in these brackets, one at each of the top corners and one at the front bottom corner, to take cylindrical shafts 5, 6, and 7 (not visible in the -drawing) to provide the bed. The shaft 6 is formed underneath with work teeth 9 for feeding a tool saddle 20 which slides along the top two shafts. The saddle may, however, be omitted in the simplest form for wood-turning operations. The saddle may be provided with a tool rest 26 carried by a cross-slide movable by a handle 25 over partly cylindrical guides 104. In the simplest form the lathe may be driven by a treadle arrangement driving a spindle 10 carrying a faceplate 15 secured on a taper 12 by a bayonet-type connection 14, 17. The headstock is rotatable about a vertical axis to enable tapers to be cut and may be turned through 180 degrees where operations on large diameter work are necessary, a separate tool rest is then used. As stages in increasing the capabilities of the lathe a lead screw 38 may be secured to the bed and driven from a central shaft 42 (in the headstock) bevel gearing, and change - speed gears (not shown). The spindle may also be driven by an electric motor 28 secured to the top of the headstock driving through chain and sprocket gear a toothed wheel 32 secured to sprocket 31 but running loose on the spindle, reduction gears 33, 35 (not shown), and 36 (fixed to the spindle) complete the drive, these wheels may be changed, a slidable mounting being provided for one pair of wheels. The bevel wheel 47 may drive a fluid pump 59 (broken lines) and flexible pressure lines are then led to a cylinder 58 and ram 63 attached to the saddle. The ram 63 is provided with rack teeth to engage a pinion 64 on one of the shafts of the saddlefeed train gears. This drive may either be used to feed the saddle or it may be engaged with the cross slide to obtain a fluid-driven transverse motion. A bevel take-off drive from the shaft 42 is also described in connection with a connecting rod and slotted disc crank drive to the saddle for cutting oil grooves on cylindrical work carried by the lathe spindle. Oil grooves may also be cut on the flat face of work mounted on the spindle by a similar arrangement at right angles to that described above.

IPC: G11B11/105
Filed: 1970-05-07
Abstract: 1304874 Magnetic storage apparatus HONEYWELL Inc 7 May 1970 [12 Sept 1969] 22186/70 Heading H3B In a Curie point memory including a magnetic film having two or more temperature dependent crystallographic phases, during the quiescent stage of operation of the memory the film is maintained within a temperature range wherein it has a single crystallographic phase. A manganese bismuth film 30 having a low temperature ferromagnetic phase with a Curie point of 360 C. and a high temperature paramagnetic phase when cooled rapidly to room temperature from above 360 C. with a Curie point in the neighbourhood of 180 C. Fig. 1 (not shown), is mounted on conductor 32 which distributes heat to the film 30 from heater 33. In accordance with the invention film 30 is maintained at a temperature of 200 C. during quiescent parts of its operation so that after heating a point on the film above 360 C. the spot returns to the low crystallographic phase. In order to write information into the film plane polarized light beam 50 from laser passes unimpeded through KDP or LiNbO 3  modulator 38 and beam splitter 40 to deflector 41 which deflects the beam to a predetermined part of film 30. The respective spot on the film is heated above the Curie point and loses its magnetization laser beam 50 is then reduced in intensity by modulator 38 and switched to another portion of the film by deflector 41 so enabling the original spot to cool down to the temperature of the heater i.e. 200 C. and become magnetized in a direction antiparallel to that of the surrounding film aided by coil 42. The information stored is read out by the polar magneto-optic Kerr effect in which the intensity of beam 50 is decreased sufficiently so as not to cause heating and the intensity of the reflected beam is detected in detector 43 as an indication of the digit stored, the intensity being determined by the degree of polarization rotation by the film 30's magnetization. Faraday effect read out may be used instead.

Title: Improvements in or relating to hose and the like and to knitting machines
Inventor: WIDDOWSON WILLIAM
IPC: D04B1/26
Filed: 1949-08-29
Abstract: 735,751. Knitting. BENTLEY ENGINEERING CO., Ltd. Aug. 29, 1950 [Aug. 29, 1949], No. 22356/49. Class 74 (2). In courses I, III, &c., a mock-seam yarn is, in wales B10, C10, drawn, along with the main yarn, through loops of the preceding course, into ordinary loops, Fig. 5, or held loops, Fig. 4, and, in intervening courses II, IV, &c., is similarly drawn into loops in wales A10, D10 and floated across wales B10, C10. A cam 17 raises needles to a tucking track 14 and, during welt formation, a bolt cam 18 raises all needles to a knitting track 13 so that they clear and take and knit a main yarn only. Cam 18 is then made inoperative and needles are selected to tuck or knit by means of a pattern drum acting through selector fingers to rock any pattern jacks 19 which bear corresponding ones of a set of selecting butts so that the jacks miss a clearing cam 20 and their needles pass at tucking height, those jacks not rocked being raised by the cam 20 so that their needles clear. This raising is effected through bits of which those 21b under four needles at the back of the leg are longer than the others 21a and raise their needles into an uppermost track 12 so that, in addition to the main yarn, they take and knit also the mock seam yarn. By the use of suitable arrangements of selecting butts on the jacks 19, a plain knitted welt may be followed by a garter band pattern of tuck stitches, a leg having a mock seam and all-over tuck effects and the usual heel, plain foot bottom and toe. To prevent the mock seam yarn dropping on to the heads of the needles as it swings across the needle circle, a yarn tensioning device, such as a cymbal device, may be followed by a spring- loaded finger or dropper: as this yarn is carried into a trapped cutter, at the end of the mock seam, the tension device is opened so that, as the dropper swings up under the influence of its spring, it can pull yarn freely from the supply bobbin.

Filed: 1951-09-25
Abstract: 706,135. Driving mechanism for wire winding machines. WHITE, J. H. Sept. 25, 1951, No. 22412/51. Class 120(2) [Also in Groups XVI, XXIV and XXXIV] A driving mechanism for a take-up roll for winding wire comprises a driving shaft, a driven shaft operating said take-up roll, differential. gearing connecting said shafts including a spider relatively rotatable with respect to the shafts, a fluid pressure system including a pump driven from the spider, means for throttling the flow through the system to load the pump and retard the spider, a brake to retard the spider and means responsive to the pressure in the system for releasing the brake. A winding spindle 20 is driven by a shaft 19 of a differential gear 17 driven by a shaft 16. The differential gear 17 comprises bevel pinions 38 and 34 on the shafts 19 and 16, respectively, and a spider 40 rotatable on bearings 41 and 42. The spider carries bevel pinions 45 and 46 and a spiral gear 50 engaging a spiral pinion 51 on a shaft 52. The shaft 52 drives a pump 55 which draws liquid from a reservoir 36 and forces the liquid through a pipe 58 to a throttle valve 59, a relief valve 66 being provided in a by-pass pipe 65. The liquid is also supplied to a diaphragm 81 to release' a brake 70 on the shaft 52, the brake normally being applied by spring pressure. At the commencement of a winding operation, the brake 70 is applied, such that the ring gear 50 only rotates at a slow speed, thus driving the pump 55 at slow speed, while the shaft 19 is driven at approximately the same speed as the shaft 16. As the diameter of the roll increases the brake 70 is gradually released, allowing the ring gear 50 to rotate faster, but slowing down the shaft 19. The shaft 19 may be braked by driving a second pump 85 which draws liquid from the reservoir 56 and supplies same to a throttle valve 90, the setting of which determines the tension with which the wire is wound.

[Also in Divisions H1 and H2] In an electric discharge device, e.g. a television C.R.T., in which an envelope containing electrodes has an external array of contact pins for at least some of the electrodes, a metal ring or ring segment 6 is provided which passes close to at least three of the contact pins to form a number of air spark gaps 8 therewith, the ring or ring segment being electrically connected to an additional pin 7. Preferably contact pins 1-5 are in a circular array and ring 6 is disposed concentrically about them such that each gap is, for example, 0À5 mm. wide to give a breakdown voltage of 2¢ kV., which voltage is less than the normal maximum operating potential difference of about 20 kV. between the final anode and control grid but is sufficient to withstand potentials applied to electrodes other than the final anode. If, in a television C.R.T., interval and external conductive coatings on the envelope are employed as the electrodes of an E.H.T. smoothing capacitor the ring should be connected to the external coating. Large resistances should also be connected in series between the electrodes and external circuitry to speed ignition of the spark gaps and afford some protection for the circutry during the flashover.
