Title: A mechanical gripper for handling objects in dangerous media or difficult of access
Inventor: MARTIN JEAN ANTOINE
IPC: G21C19/105
Filed: 1967-04-17
Abstract: 1,135,535. Article engaging devices for lifting. GROUPEMENT ATOMIQUE ALSACIENNE ATLANTIQUE (G.A.A.A.). 17 April, 1967 [18 April, 1966; 27 Feb., 1967], No. 17619/67. Heading B8H. When an article engaging device 1, Fig. 1, is supporting a load from gripping fingers 10 a sliding member 4 is held in its upper position against a shoulder 1a by the suspension cable 6. If the body of the device or the load is rested on a support, the member 4 descends until its base rests on an annular stop 22. Simultaneously a pivoted locking member 19 abuts the stop 22 and moves to an inclined position. As the slide 4 moves down, the fingers 10 are moved inwards to release the load by pins 16 which slide in slots 18. When the device is raised by the cable 6 the member 19 engages a shoulder 1<SP>1</SP>, Fig. 4, to prevent further upward movement of the slider 4, thus maintaining the fingers 10 in the open position. When the device is lowered on to another load the member 19 is turned to a horizontal position by the stop 22 and in this position it does not impede subsequent upward movement of the slide 4 with consequential movement of the fingers 10. To prevent the load being released due to the device striking an obstruction, pivoted arms 23 may be provided which lock the slider 4 in its upper position. These are not released until the device is lowered into a conduit which bears on wheels 30 on the arms 23 and pivots the latter out of engagement with the slide 4. Alternatively, the member 19 may have two notches at each end, Fig. 7, so that the cable 6 has to be slackened twice before the arms 10 release the load. Fig. 13 illustrates an embodiment which provides a frictional grip on the load. Three wheels 33 mounted on pivoted arms 34 are wedged against the inside surface of the load when a grooved member 41 attached to a vertically sliding member 4 is raised by the support cable. A locking member 19 is provided as before. The pivoted locking arms described with reference to Fig. 1 may be provided with this embodiment.

Title: Signalling circuits including echo suppressors
IPC: H04B3/20
Filed: 1963-05-09
Abstract: 1,033,934. Echo suppressors. WESTERN ELECTRIC CO. Inc. May 9, 1963 [May 16, 1962], No. 18323/63. Heading H4R. In an echo suppressor for a four-wire, twoway signalling system, the transmission efficiency of the outgoing path is varied in accordance with at least the signal in the incoming path, in addition the dynamic range of control of the transmission efficiency of the outgoing path is varied by a means differentially responsive to the signals in the two one-way paths while the sensitivity of the control of the transmission efficiency is varied by means responsive to noise in the circuits. Fig. 1 shows a transmission system connecting terminal stations E and W, transmission taking place over two-wire local circuits 10 and 25 interconnected by hybrid networks 11 and 23 with a four-wire system including two one-way transmission systems 19 and 27. Echo suppressors are provided at each end of the fourwire circuit, one suppressor being shown in detail, the other represented by block 20. The echo suppressor comprises a pair of variable impedance devices 15 and 17 in the outgoing line from terminal W; the impedances being controlled by the output of a network 37 differentially responsive to the signals in the outgoing and incoming lines 12 and 13, the attenuation in line 12 increasing as the input on line 13 rises with respect to the output on line 12. The control signal path from the differential network 37 to the variable impedances 15 and 17 includes resistors 60 and 62 and vario-lossers 68 and 71. Resistors 60 and 62 are normally short circuited, but during periods of " double talk," i.e. speech signals on both lines, trigger circuit 56 operates and opens the relay contacts 58 and 59 and reduces the range of suppression available from the variable impedance devices 15 and 17. Sensitivity of the control of the variable impedance devices is varied by the vario-lossers 68 and 71 which are operated in response to noise on either line by NOGAD's 67 and 70.

[Class 112] The driving mechanism of the trimming device described in Specification 455,001 is modified by improved mounting of the electric motor and its couplings to the knife-actuating shaft. Lubrication devices are also provided. The feed and needlevibrating mechanisms are the same as those described in Specification 374,322. A bracket 20 provides bearings for the knife bar 21 carrying the knife 23 which severs the work parallel to the line of seam formation. The knife bar 21 is reciprocated by the bar 28 via a link 26 and collar 25, when the pin 31 on the crank-arm 32 on the rock-shaft 33 is engaging with the slot 30 in the bar. The shaft 33 can move axially and has a circumferential groove 35 embraced by a notched yoke 36 on the hand lever 37 for disengaging the pin 31 and slot 30. The pin and slot are re-engaged to put the trimmer into action by a lever 43 having an extension 45 which engages the upper end of the knife bar to depress it till the pin enters the notch. The shaft 33 is rocked by the electric motor 73 which is independent of the motor driving the sewing machine. The shaft 33 carries a rock-arm with arms 51, 52 with a pitman 58 between them. The opposite end of this pitman embraces a crank-pin 59 extending from the disc 60 at the end of the rotating shaft 61. This shaft is driven from the motor 73 by the belt 70 and pulley 69. The cutter mechanism can be put out of action by the lever 43 or by stopping the motor 73. Its speed may be varied independently of that of the sewing machine. The machine may trim without sewing by removing the sewing-needle. Lubricating. The arms 51, 52 receive a pin 53 with a longitudinal bore 54 receiving a lubricating wick 55, the bore 54 being intersected by radial ducts 56. To supply lubricant to the bearings of the shaft 61, the bracket lugs 65, 66 are provided with bosses 77 with nipples 83 communicating with wells 79 containing a wick 82, Fig. 5, supplying oil to the grooves 84 in the bushing. The pitman 58 also has a longitudinal groove of which the upper end is enlarged to form an oil reservoir. A C-shaped oil guard bracket 91 collects lubricant in its base and prevents splashes being thrown off.

Abstract: 845,215. Mechanical calculating-apparatus. GERBER SCIENTIFIC INSTRUMENT CO. June 11, 1957, No. 18379/57. Class 106 (1). [Also in Group XX] The graduations of a scale are formed by the convolutions of an extensible coil spring 46, Fig. 1, mounted adjacent but slightly 'rearwardly of the edge 16 of a base member 12 and protected by a transparent cover 90, Fig. 11, having a tapering edge 96 which, by its prismatic effect, causes the convolutions of the spring to be seen at the edge 16. The front part of the base is formed by a plate 14 rebated to the underside of the main base member. Transverse members 18, 20 span the base. The front end 22 of the member 18 is slotted at 54 for a screwretaining bracket 62, Fig. 8, to which one end of the spring is secured. The other end of the spring is similarly attached to the front portion 44 of a longitudinally slidable member 34 guided by tongue and groove engagement of the depending portion 36 with the front edge of the main base member and by spring-loaded members 43a engaging a groove 43 in one wall of a channel 30 in the base. The members 18, 20 carry adjustable stops 66, 68 which limit the movement of the member 34. They also carry the cover 90 and a rod 70. As the spring 46 is extended, another spring 76 carried on the rod 70, is also extended. The spring 76 carries on spaced convolutions numbered tabs 86 by which particular convolutions of the spring 47 may be identified. Different convolutions may be differently coloured to assist identification. The member 34 carries a cursor 112 moving over a plate 108 secured by screws 110 and carrying scales 106 which may be linear or logarithmic or represent trigonometrical or power functions. The cursor has a line 114 against which the scales may be read and a runner 118 for identifying the scale in use. The cursor also covers an area 120 on which may be drawn a graph representing an empirical or other function for which a scale is not provided, the values of the function being plotted as abscissµ against values of the variable represented as equally spaced ordinates. The Specification describes how the instrument may be used to draw, or interpolate between, points spaced in accordance with a particular function. Thus the graph 120 may represent the response function of a non-linear recorder. The instrument may be used to correct the recorded values for the characteristic of the recorder. In one modified embodiment the spring 46 is dispensed with and the spring 70 used alone. In another, the plate 14 is transparent and provided with a linear scale.
