Title: Measuring apparatus
IPC: G01B7/293
Filed: 1974-08-07
Abstract: 1479621 Setting up measuring apparatus RANK ORGANISATION Ltd 6 Aug 1975 [7 Aug 1974] 34767/74 Headings G1M and G1N The invention relates to the setting radially with respect to a fixed axis the pick-up 11 of a measuring instrument of the type comprising a rectilinearly movable slide 2b carried by a workpiece table 2a, the pick-up being relatively rotatable with respect to the workpiece table about the fixed axis. The method of setting comprises the steps of locating on the slide 2b about the fixed axis a reference body 4 having a cylindrical or part cylindrical surface and traversing the pick-up over at least a portion of the curved surface of the body 4 by providing said relative rotation and, to provide a measurement of the distance of the pick-up from the fixed axis, either adjusting the position of the slide 2b with respect to the work-table until the pick-up output signal is substantially constant at a certain value or observing the eccentricity of the relative rotation using a computer. The slide 2b is then adjusted by a selected distance followed by adjustment of the radial position of the pick-up until it again contacts the aforesaid curved surface or a different portion of the surface of the body. The relative rotation about the fixed axis is further effected as an oscillator so as to produce a "turning" point in the pick-up output signal and then the radial position of the pick-up adjusted to adjust the output signal to a selected value. Preferably the selected value is equal to the abovementioned certain value. The method is described with reference to a hollow semi-cylindrical reference body Fig. 3 (not shown), and a cylindrical solid body Fig. 4 (not shown).

Title: Improvements in and relating to methods of and apparatus for regulating electric resistance heating apparatus
IPC: H01H37/20
Filed: 1938-11-29
Abstract: 521,970. Thermal switches. BRITISH THOMSON-HOUSTON CO., Ltd. Nov. 29, 1938, No. 34792. Convention date, Nov. 30, 1937. [Class 38 (v)] [Also in Group XXXV] In electric resistance heating apparatus the current is regulated by steps with intermediate regulation between steps by means of mechanism c o ntrolled by a single operating member arranged to produce the step regulation when in predetermined positions and to effect progressive regulation while being moved between the predetermined positions. The operating handle, Fig. 1 (not shown) rotates an axle on which is fixed a drum carrying contact members which co-operate with fixed contacts 4, 5, 7-9, Fig. 6, connected respectively to the line wires, a mercury interrupter 11, and resistance elements A, B the arrangement being such that the switch contacts have three positions corresponding respectively to " off," element A heated, and elements A and B connected and heated in parallel. A bimetallic strip 15, Fig. 8; mounted adjajcent to a current-carrying heater coil 16 is adapted, when actuated, to bend upwardly against the lower end of a pivoted rocker arm 18 carrying the mercury interrupter 11, which opens the circuit through the elements when titled from its horizontal position. Movement of the bimetallic strip 15 is controlled by a cam 23 on the end of the axle 2, so that after element A is brought into circuit by an initial rotary movement of the controlling handle, the duration of the periods of current supply to the element is increased progressively by rotating the cam 23 into its higher positions, until the bimetallic strip and the end of the rocker arm are held so far apart that the contact-breaker is inoperative and element A is heated continuously. Further rotation of the operating handle to insert elements A and B in parallel may either reintroduce the interruptor or, as in the example, maintain it inoperative, so that the two. elements are heated continuously. A locating device to hold the rotary switch drum in a set position comprises a cam disc mounted on the axle 2, and co-operating with a roller which is carrier on a spring-controlled lever. When element A alone is energized, as shown in Fig. 6, it is shunted by the thermostat heater coil 16 in series with elements B, the combined resistance of these latter being such that the heating effect of'B is negligible.

Title: Gear with gradually changeable ratio
IPC: F16H29/04
Filed: 1930-11-19
Abstract: 362,139. Variable speed gearing. NEURATH, W., 53, Franz Josefs Kai, Vienna. Nov. 19, 1930, No. 34811. [Classes 80 (i), 80 (ii), and 80 (iii).] Variable-speed ratchet gearing with variablethrow driving cranks 14 in quadrature is modified to secure uniformity of speed of driven shaft 22. In such an arrangement with two cranks at rightangles, there are four fluctuations in the speed transmitted per revolution of crank shaft 8. The shaft 8 is therefore driven from a uniformly-rotating driving-shaft 1 so as to have four compensating fluctuations in its own speed. In one arrangement, the shaft 1 is connected by a sfider-crank pair 3, 6, Figs. 1 and 2, to a parallel shaft 4 connected to the shaft 8 by a spur pair 10, 9. The cranks 14 are connected by rods 16 to racks 18 meshing with four ratchet-mounted pinions 27, 26 on the shaft 22 and on a shaft 21 geared thereto. The effect of the obliquity of the connecting-rods 16 in disturbing the uniformity of speed is compensated for by means shown in Fig. 6. The far ends 17 of the connecting-rods 16 are guided rectilinearly by idle sliders 61. The racks 18 are connected by auxiliary connecting-rods 59 jointed to the connecting-rods 16 at intermediate points 58. The rods 59, 16 slope in opposite directions and their obliquities mutually compensate. Alternative means for driving the shaft 4 of Figs. 1 and 2 from the shaft 1 is shown in Fig. 7. The shaft 1 is inclined to the shaft 4 and is driven uniformly through a gear 64. The fluctuating speed of the shaft 4 is effected by a connection consisting of a curved pin 51 projecting from a disc 5 on the shaft 4 into a slot 52 in a disc 2 fast on the shaft 1. A second shaft 62 with fluctuating speed carries a flywheel 63 to further equalize the motion. In the arrangement of Figs. 1 and 2, the speed is varied by the relative angular displacement of scrolls 34 engaged at 41 by blocks 40 carrying the cranks 14. The scrolls are geared by a shaft 37, Fig. 1, and are displaced by sliding a nut 48, Fig. 2, relatively to helical and straight parts 47, 43 turning with the shaft 8 and with the scrolls, respectively.

Title: A method and machine for forming helical lock seam pipe
IPC: B21C37/12
Filed: 1962-09-12
Abstract: 974,097. Making helically seamed tubing. LOCKFORMER CO. Sept. 12, 1962 [Dec. 6, 1961], No. 34814/62. Headings B3E and B3J. A method of making helical lock seam pipe from continuous metal strip comprises moving the strip longitudinally and during such movement forming a flange along one edge and a channel along the other edge, guiding the flange along a helical path and into the channel by means which engage opposite faces of the strip along the juncture between the flange and the remainder of the strip, leaving the said remainder of the strip free and unengaged. Strip 20 from a coil 48 supported on a drum 52 carried by an extension 50 of a main frame 1 passes around flanged wheels 55 through grooves 60 in side guide plates 58, 59 to three pairs 2, 3, 4 of driven rolls. To support a coil 48 of narrow strip a spacer ring, Fig. 14 (not shown) is fitted over the drum 52 and spaced from one flange thereof. The frame 1 is adjustable about a vertical pivot 42 by a gear 45. The rollers 5 and 8 of pair 2, and 6 and 9 of pair 3, are so shaped, Fig. 12, as to form a flange 71 and a channel 72 on the strip edges. The rollers 7 and 10 of the pair 4 have adjustable ring members 83, 89, Fig. 13, which further bend the flange 71 and channel 72 over to compensate for spring- back. Staggered ribs on the rolls allow heavy gauge metal to spring slightly therebetween. As the strip approaches a coiling head 40 on the frame it is engaged, at the junction of the flange 71 with the remainder of the strip, between inner and outer helical rods 93, 92 which force the flange along a helical path. A third rod 95 may be provided to engage the flange 71. From the rods 92, 93 the flange passes under a convex guide shoe 99 which directs it into the channel 72, the seam then passing between rollers 27, 29, Fig. 3, to compress and lock it.

Title: Improvements relating to the beam processing of a workpiece
Inventor: BOEHM HANS
IPC: B23K15/02
Filed: 1969-07-11
Abstract: 1,205,540. Programmed control of beam machining. INTERNATIONAL BUSINESS MACHINES CORP. July 11, 1969 [July 23, 1968], No.34978/69. Heading G3N. A programme for controlling an electron, ion or laser beam processor is generated by causing the beam 5 to scan a pattern 53 having marks 54 corresponding to points at which a workpiece is to be processed (welded or drilled ), producing a signal in response to the beam impinging on a mark, and storing a representation of the position of the beam when said signal is produced. The processor has X and Y deflector coils or plates 6, 7 energized via amplifiers 29, 30 and digital/analogue converters 27, 28 by counters 25, 26 in which the magnitude of the deflection is represented in binary form. During processing, instructions are fed to the counters from a magnetic tape or other programme source 9, which also instructs devices 32, 33 controlling the strength and duration of beam pulses, or device 31 which produces a train of pulses. For creating the programme the circuit shown in thick lines is used. The beam is caused to scan a pattern 53 with a raster type movement by supplying continuous pulses from a generator 50 to the X counter 25, which when full sends one pulse to the Y counter 26 and recycles. Impingement of the beam on a printed or metallic mark 54 is detected by a photo-cell, photo-multiplier or scintillator 55 sensitive to reflected light or secondary electrons and a signal is passed through an AND gate 57 to a "clock" 60 and to an inverter 58 which closes another AND gate 52 to interrupt the scanning of the beam. The clock 60 switches the programme 9 to the receive mode and opens gates 66, 67, 68 which pass the counts in the X and Y counters and external information 69 on beam pulse strength and duration to the programme store. It also closes AND gate 57 to interrupt the signal from detector 55 so that gate 52 is again opened and scanning resumed.
