Title: Improvements in or relating to sextants and similar instruments for angular measurement
Filed: 1937-06-07
Abstract: 490,621. Integrating - apparatus. EVERITT, P. F., HUGHES, A. J., and HUGHES & SON, Ltd., H. June 7, 1937, No. 15699. [Class 106 (iv)] [Also in Group XX] In a sighting instrument for measuring angles the rotatable part is coupled to fine adjustment mechanism through interengaging members which can be disconnected and reconnected again with the part in one of a series of predetermined, equally spaced, angular positions from its original position, the angle between adjacent predetermined positions being not greater than the range of adjustment provided by the fine adjustment mechanism. In the sextant shown a lever 7 with a circular head 8 having three groups of spaced holes 11 is pivoted on the frame 14 in a tapered bearing 13 and may be given a limited angular movement by fine adjustment mechanism. The index mirror 1 is carried by a disc 3 having three pins 6 for engagement with the holes 11. The pins 6 are held in the holes by a spring 15 bearing on the inside of a knob 17 at the end of a spindle 18 projecting from the disc 3 through the hollow conical centre 12 of the lever 7. By compressing the spring 15 the pins 6 may be disengaged from the holes 11 and the disc 3 coarsely adjusted to a fresh position by turning the knob 17 and re-engaging the pins with a different set of holes. The free end of the lever 7 carries a bolt 21 projecting into the frame 14 and carrying a head 23 which is pressed by a spring 25 into contact with a micrometer screw 26. The latter engages a threaded bracket 27 and carries a gear wheel 29 by which it is driven from the knob 45, Fig. 2, through splined drum 31 and gearing 34-42. The drum 31 has a worm thread 57 driving a wheel 58 graduated to indicate units of degrees of the setting, minutes being indicated through a window by graduations 53 on the drum 31. Tens of degrees are indicated by a projection 19, Fig. 3, on the plate 3 and a set of graduations on the frame 14. During each observation one sixth of the fine adjustment imparted by the screw 26 is registered through a clutch 71 by a counter 65 which therefore after six observations indicates the average reading. Ratchet mechanism is provided for counting the number of observations, which is indicated on a dial 100, and for causing a screen to move to obscure the bubble level after the completion of the six readings. In use the clutch 71 is disengaged after each observation and the fine adjustment mechanism restored to zero. Disengagement of the clutch is effected through a lever which during its movement causes the ratchet mechanism to be stepped on until after six operations of the lever the ratchet permits the screen to move to the obscuring position. The screen is withdrawn before commencing a fresh set of observations by rotation of the disc 99.

Abstract: 755,568. Control systems for resistance welders. FORD MOTOR CO., Ltd. (Ford Motor Co.). May 27, 1954, No. 15730/54. Class 38 (4). To ensure that flow of welding current, and the timing thereof, is initiated only when the electrodes are making good contact with the work, the contactor, or ignitrons 17 through which the welding transformer 15 is supplied is shunted by an impedance, such as a transformer 18, the change of voltage across which, when the electrodes firmly engage the work, is sufficient to operate means for effecting closure of the welding contactor, or opening up of the ignitrons. In the arrangement shown, transformer 18 applies an A.C. " turn-on " voltage of adjustable value to the grid of a thyratron 20 which is normally held non-conducting by an adjustable D.C. bias obtained over a rectifier and potentiometer 21 from a transformer 23. The " turn-on " and bias voltages are so adjusted that the thyratron fires only when the electrodes are in good engagement with the work and the primary winding of the welding transformer 15 consequently presents little impedance in series with transformer 18. Firing of thyratron 20 operates a relay 25 which controls the contactor, or ignitrons 17.

Title: Improvements in straight frame knitting machines
IPC: D04B27/26
Filed: 1924-07-02
Abstract: 231,814. Hirsch, L., and Zahn, H. April 5, 1924, [Convention date]. Parallel, straight-bar, and warp machines.- For traversing the elements of a straight knitting machine, such as the guide bars of a double rib warp machine, a perforated paper band 110 is used to indicate merely the length and direction of a movement, the point of application being determined by the sum of the previous movements. The band 110 carries the selections for all the guide bars. The jacquard pins 120 for one bar only are shown. Each pin 120 is connected to a sliding selecting bar 140 located between the two lugs 161 of a vertical member 160 having an integral horizontal arm 165. Advance selection is made possible by the pivoted claw members 150, 155 actuated by a cam 156 on the main drive 105 so as to be raised and lowered respectively to clamp the unselected bars 140 and tip up the selected ones thereby raising the corresponding vertical members 160. A locking bar 157 is then pushed into notches 158 in the members 160 to retain the members 160 in the positions given them by the claws 150, 155 which are now swung apart and a new selection made. Slidably connected to each horizontal arm 165 are coupling pins 220, all the pins concerned with one guide bar being set in a row in a slide frame 250, a corresponding number of holes being provided in a member 202 sliding in a lever 200 oscillated about a pivot 201 by a cam 206 on the main drive 105, the arrangement being such that when a coupling pin 220 is raised by the selecting means, it passes into a hole in the sliding member 202 so that oscillation of the lever 200 moves the slide frame 250 by an amount depending on the distance between the lever pivot 201 and the particular coupling pin 220 selected. The mechanism for applying the movements of the slide frame 250 to the guide bar 50 comprises two racks 350 on the forked end of the slide frame and a pinion 360 which is engaged by either rack, so as to be capable of rotation in either direction by a system of levers &c., including a rocking member 320, operated by a cam 306 on the main drive 105 to raise or lower the racks, the direction being determined by a special vertical member 160 connected by a wire 167 to the rocking member 320 and operated by the jacquard. The pinion 360 rotates a vertical rod 365 which reciprocates, by a rack and pinion, a racking bar 370 connected to the guide bar 50 so as to permit the necessary swinging movement of the latter. A wedge 361 engages the pinion after each movement.

Abstract: 906,689. Weighing-apparatus. METTLER, E., [trading as METTLER, FABRIK FUR ANALYSENWAAGEN, E.]. May 3, 1961 [Nov. 7, 1960], No. 16074/61. Class 143. An unsymmetrical balance beam has analytical or micro-balances, having a central knifeedge, an outer knife-edge on one of its balancearms and a counterweight on the other, is characterized in that the balance beam is provided with a slot 17 disposed transversely to its longitudinal direction, that the two sections 7, 10 of the balance beam on either side of this slot are held together by a connecting member 18 spanning the slot, and that the connecting member is made of a material having a different linear coefficient of expansion from that of the material of the beam. If the beam is of aluminium alloy, a suitable material for the connecting member is anti-magnetic stainless steel, or titanium. If the temperature rises the coefficient of elasticity increases and the longer section 10 tends to droop, but the expansion of the area 19 of the beam below the slot being greater than that of the connecting member 18 causes the latter to exercise a tensile action in counteraction. Reverse reactions happen with a lowering of temperature. The connecting member is preferably of H-section, the flanges embracing the beam, to which they are fastened by cementing with synthetic resin and pinning. Instead of the slot extending downwards from the top, it could extend upwards from the bottom edge, in which case a suitable material for the connecting-member would be zinc. The balance beam may also have several slots with a connecting member in each.
