Title: Improvements in or relating to power manipulators
Inventor: FOSKER ERIC JOHN
IPC: B25J5/04
Filed: 1962-08-02
Abstract: 970,441. Manipulators. GENERAL ELECTRIC CO. Ltd. July 24, 1963 [Aug. 2, 1962], No. 29752/62. Heading B4Q. A manipulator comprising a carriage 7 traversable on a gantry 8 running on rails 10 carries a handling appliance 1 on an arm 2 pivoted to the lower one 4 of three telescopic tubes 4 . . . 6, these tubes when in their retracted position being nested within one another and stowed within the carriage. An electric hoist (not shown) on the carriage 7 controls the extension of the tubes by hoist cables 18 passing round pulleys 19 secured to the tube 5. The tube 6 is guided by rollers 12 carried by a shroud 11 secured to the base of the carriage 7, the tube 5 is guided by rollers 14 secured to the tube 6 and the tube 4 is guided by rollers 16 secured to the tube 5. The tube 4 is coupled to tube 6 by chains 22 connected at their ends to the tubes 4, 6 and passing over sprockets 23 carried by the tube 5. The tube 5 is coupled to the tube 6 by chains 20 connected at their ends to the tube 5 and shroud 11 and passing over sprockets 21 carried by the tube 6. The combined weight of the tube 4, arm 2 and appliance 1 is greater than the weight of the tube 6 and thus the chains 22 are held in tension and maintain the sprockets 21 in engagement with the chains 20. If the tube 5 is raised or lowered at a uniform speed by the cables 18 the tube 6 moves at half that speed and the tube 4 at one-and-a-half times that speed. Thus the appliance 1 is raised or lowered at a uniform speed over its entire range of movement.

IPC: H03K5/26
Filed: 1970-06-22
Abstract: 1286166 Pulse circuits COMMISSARIAT A L'ENERGIE ATOMIQUE 22 June 1970 [7 July 1969] 30193/70 Heading H3P Apparatus for selecting pulses from a train of pulses Ix of random width and position by a second train Ia of pulses of the same type so that only the first pulse in Ix to appear after the start of a pulse in Ia is passed to form an output train Is (i.e. the shaded pulses in Ix appear in Is) comprises two sets of logic elements 2, 12 in which the trains Ix and Ia are combined to control a four stable state circuit 4 and a bi-stable circuit 14, one output of each being connected to the opposite combining section, and the one output of bi-stable 14 is connected to an AND gate 16 together with the Ix pulse train to produce the output train Is. The bi-stable 14 remains in a state in which its effective output is " 0 " until a pulse occurs in train Ia but not in Ix, whereupon it becomes " 1 ". When a pulse also occurs in Ix the AND 16 is enabled to produce an output pulse Is. The pulse in Ix also changes over the circuit 4 which locks 14 in the " 1 " condition until the end of the Ix pulse. Thus the Ix pulse is transmitted completely even if Ia ends in the meantime. The end of the Ix pulse resets 14 to " 0 ", in which condition it is held until the start of the next pulse in Ia. Thus, subsequent pulses in Ix which occur before the start of the next Ia do not appear in the output Is. Two embodiments are described which give details of the arrangements of logic elements in the circuits 2, 12 and 14, the second of which requires delaying the Ix pulses in a device 6. The four stable state circuit comprises two associated bi-stable circuits, the four internal consecutive stable states thus obtained being controlled by four intermediate transition thresholds (at the input), the arrangement being such that two thresholds corresponding to rising input levels are greater than two thresholds corresponding to falling input levels. It is stated that the four stable state unit may be replaced by a bi-stable unit and a single-pulse generator. The invention is for use where computers having independent " clocks " are to be interconnected.

Abstract: 1,166,052. Moulds. BRITISH IRON & STEEL RESEARCH ASSOCIATION. 20 June, 1967 [6 July, 1966], No. 30274/66. Heading B3F. An ingot mould assembly, particularly for use in electroslag remelting a consumable electrode, comprises side walls 1 and corner plates 2 that produce obtuse angle corners on the cast ingot, a trough 3 arranged around its lowermost end for collecting coolant, and water inlets 6, 7 positioned in the trough 3 and which are connected to feed passages formed on the corner plates 2 for supplying water to a header 4 that includes discharge apertures for feeding water on to the exterior faces of the side walls 1. In an alternative embodiment (Figs. 3 and 4, not shown) the feed passages are omitted and fins (9) are positioned at each junction of a side wall and a corner plate. Coolant is directed on to the exterior surface of the corner plates 2 and on to the fins (9) as well as on to the side walls 1, from a header. In use the mould assembly and cooling arrangement allows a thicker slag skin to form on the corners of the casting which is said to minimize segregation at the columnar crystal junction within the corners of the cast ingot. The open-ended mould may be tapered by having rectangular side walls 1 and traperzoidal corner plates 2 and in use is positioned on a suitable base-plate.

Title: Improvements in or relating to devices for rotating and reciprocating an element such as a tool or workpiece
IPC: B24B33/02
Filed: 1939-11-17
Abstract: 536,683. Honing and like machines. MICROMATIC HONE CORPORATION. Nov. 17, 1939, No. 30281. Convention date, May 22. [Class 60] [Also in Group XXII] A device for rotating and reciprocating a honing or other tool or a work holder, as described in Specification 493,949, comprises a shaft 22 disposed in casing 15 and connected to the tool or holder which extends from one end of said casing and means for rotating and reciprocating the shaft in timed relation. The tool or work holder is mounted by means of a hollow shaft 38 in the right hand end of the hollow shaft 22 and is expanded and contracted by a sleeve 34, moved axially in the shaft 38 by a piston 31 and fluid supplied through passages 23, 18, 35 and 24, 19, 36. The shaft 22 is secured by a pin 27 to a hollow shaft 26 on which is pivoted, by means of two balls 60, a swash plate 58 the angle of which can be adjusted by a pin 64 and spaced flanges 63 of a sleeve 62, which can be moved axially by a pin 71 engaging an annular groove of a shaft 66, screwed at 67 to engage the shaft 26 and rotatable by a knob 74. The shaft 26 and swash plate 58 are rotated by a grooved pulley 42 and belt from a motor and the inner ring 56 of the swash plate may be rotated and prevented from moving axially by a ball 55 thereof which engages a radial cylindrical groove 54 in a disc 53 having teeth 52 which engage radial grooves in the end plate 49 of a sleeve 44 driven by a pulley 40 and belt from the same motor as the pulley 42 but at any desired different speed. The adjustment of the swash plate varies the length of the axial displacement of the tool or work holder. If the amount of expansion is to be varied, e.g. in the case of a hone 111, Fig. 5, the spindle 99, which has tapered walls to engage the abrading stones 105, is connected to the actuating sleeve 34 by a member 79 having right and left hand threads 83, 82 and external teeth 86 engaged by a pinion 87 pivoted in the shaft 38 and rotatable by a band-operated internally-toothed sleeve 89. When the member 79 has been rotated, to adjust the position of the spindle 99 by means of this sleeve 89, it is locked by a projection on a spring-pressed sleeve 93. The casing 15 may be charged with lubricant through a hole 175 and can be mounted together with its driving motor, vertically or horizontally, singly or in an opposed pair, on a fixed frame or on a movable slide or on a machine for boring &c. The Specification as open to inspection under Sect. 91 stated that the device could carry a boring, drilling, reamering, or burnishing tool. This subject-matter does not appear in the Specification as accepted.

Filed: 1962-08-09
Abstract: 986,866. Artificial limbs. HUGH STEEPER Ltd. Aug. 6, 1963 [Aug. 9, 1962], No. 30595/62. Heading A5R. Means for locking and unlocking an elbow joint with alternate pulls on a control cord comprises a pivoted member which is rocked between two positions in one of which it allows a detent to engage a locking quadrant while, in the other, it holds the detent disengaged. When the cord 5H, Fig. 1, is initially pulled, a lever assembly 5 is raised about a pivot 5D and lifts a spring-loaded detent 3C clear of a toothed locking quadrant 3K attached to the forearm 3L. This allows a spring-loaded latch 4A to turn counterclockwise about its central pivot so that its upper surface engages beneath the detent 3C and holds it raised. On subsequent release of the cord 5H the latch 4A is prevented from turning by the detent 3C and its rear surface 4C engages the right-hand pin on a sliding member 6, Fig. 2, which it moves to the right. The subsequent pull on the cord 5H, Fig. 1, consequently brings the lefthand pin under the beak on the member 4C and causes it to tilt clockwise and disengage detent 3C which is, however, still held by the lever 5. However, final release of the cord 5H allows it to drop into engagement with the locking quadrant 3K while the left-hand cam surface on the pivoted member 4C moves the slide 6 back towards the left.

Filed: 1949-11-29
Abstract: 698,612. Fluid-pressure servomotor-control systems. NEGRETTI & ZAMBRA, Ltd., and IBBOTT, H. W. June 12, 1950 [Nov. 29, 1949], No. 30636/49. Class 135 A measuring apparatus comprises a member 1 pivoting about an axis X-X which is given a torque by a force P1, acting at a set distance from the axis, and produced, e.g., by pressure in a bellows B1 and an opposite torque given by a force P2, produced, e.g., by the bellows B2, acting on arm 3 carried by a rotatable spindle 2 on the member perpendicular to its axis, and a third force or displacement P3, produced, e.g., by the bellows B3, for rotating the spindle through an arm 4, means actuated by displacement of the member 1 to control the torque relationship between the forces PI, P2 and maintain the member in equilibrium, and a meter 12 for effecting the measurement, actuated by said means. The force P2 acting through the strut 7 exerts no torque on the spindle 2, while the force P3 exerts no torque on the member 1. It is shown that PI is proportional to P2xP3 so that the meter, measuring the pressure Pn supplied to the bellows Bl and to the nozzle 11 controlled by the member 1, gives an indication of the product of two variables P2, P3 or the square of the variable if P2 and P3 are equal. By measuring the pressure behind the nozzle when it is connected (a) to bellows B3 or (b) to bellows B2 and B3, the meter will measure (a) the quotient P1/P2 or (b) the square root of P1. The member 1 may move between two nozzles leading from diaphragm chambers supplied with air under pressure, the diaphragms actuating a double-beat air-supply pressure leak-off valves. The air pressure drop across an orifice may be applied across the bellows B1, so that the meter measuring the pressure behind the leak-off valve connected to the bellows B2 and B3 gives an indication of the air flow through the orifices In a further application the depth of a liquid is measured by forcing air out of two pipes at depths H1, H2, Fig. 2 (not shown) in the liquid, and applying the pressure drops across the depths H1, H2, across the bellows B1, B2, respectively. In another application, in which power is measured by multiplying torque and speed, the force P3 is controlled by a transmission dynamometer, and the forces P1, P2, are provided by a magnet energized by current from a generator geared to the transmitting shaft.

Title: Improvements relating to the manufacture of slide fasteners
Inventor: MACKIE DAVID WILLIAM
IPC: A44B19/60
Filed: 1959-09-09
Abstract: 901,543. Sliding clasp fasteners. LIGHTNING FASTENERS Ltd. Sept. 2, 1960 [Sept. 9, 1959], No. 30765/59. Class 44. [Also in Group V] The invention comprises a method and apparatus for forming the second end-stops on individual slide fasteners carried and spaced on a continuous length of tape, whilst the sliders of the immediately preceding fasteners are held up against the first end-stops previously provided on the said preceding fasteners. The length of fasteners with each slider lying rearwardly is pulled through the guide slot 3 until the first slider engages two fingers 15 and 16 and the slider moves towards the first endstop. The slider then forces the fingers outwardly to operate a micro-switch 14 by means of a plunger 18, the said switch being connected so as to energize the end-stop forming device which may comprise one radio frequency welding electrode 9 supported by a pivoted holder 8, and a solenoid 13 operated mechanism for rocking the holder to move the said electrode towards a similar electrode 11. The fastener chains which are made of thermoplastic material are thus welded together. After the welding the operative raises part of the fasteners which have passed through the fingers and this disengages the pull 21 from the stop-member 19 and the slider passes through the fingers as shown in Fig. 1. The process is repeated. A mechanical drive may be employed to pull the length of fasteners through the apparatus and a means for disconnecting this drive when the microswitch is actuated. The stop-member 19 can then be dispensed with.
