Filed: 1970-10-12
Abstract: 1332667 Load-engaging devices PROGRAMMED & REMOTE SYSTEMS CORP 12 Oct 1970 [14 Oct 1969] 48378/70 Heading B8H A grapple assembly, particularly for handling mill liners comprises a base 45 which is attached to the boom (22) of an articulated boom assembly (10), Fig. 1 (not shown), which is attached at a support (11) in the interior of a mill, the grapple assembly comprising a rotatable tubular member 58 closed by a plate 59 which is recessed in the base 45, the member 58 being rotatable by means of a motor 72 and associated gear 73, a swivel sleeve or collar 80 which is connected to the member 58 by means of a flange 81 and to an outer support member 84 by a flange 82, the flanges 81, 82 being free to move respectively in recesses 61, 83, the recess 83 being formed in a support member 84 mounted on the outer end of the sleeve 80. An hydraulic ram 93 mounted in the interior of member 58 for rotation therewith has a hook 101 connected to its rod 99. In operation the hook 101 is attached to a member 102 on a mill liner section 92, and when the rod 99 is retracted, it pulls the section 92 towards two support members 91 mounted on the support member 84 which causes the wall 85 of member 84 to abut against and move the sleeve 80 inwardly to abut the surface 62 of the member 58. When the hook 101 is not tightly pulling the member 92, the collar 80 may be moved angularly by a limited amount as shown by the dotted lines by virtue of the recess 61 thus providing manoeuverability of operation. The grapple assembly is movable relative to the boom (22) about two orthogonal axes by means of hydraulic rams (37), (49), while the boom assembly (10) is rotatable relative to the support (11) by means of a power rotatable mounting assembly (12).

Title: Method and apparatus for the high speed transmission and reception of two-level images
Inventor: MOSCA VIRGILIO
IPC: H04N1/17
Filed: 1968-10-15
Abstract: 1,243,365. Facsimile systems. V. MOSCA, and M. BONFA. 15 Oct., 1968. [26 Oct., 1967], No. 48754/68. Heading H4F. A method for the high-speed transmission and reception of an image comprising highspeed scanning the image to produce a video signal, stopping the scan on detection of the video signal reaching a predetermined threshold and generating a pulse signal of predetemined duration for transmission to the receiver, maintaining said stopped scan state for said duration and thereafter causing the resumption of said high-speed scan. In the transmitter of Fig. 1, the video signal A is passed via an adder circuit 1 to a level discriminator 2 which converts the video signal into a binary-quantized form referenced to a predetermined threshold. Each upward step of the output of 2 (a threshold up-crossing) is converted to a spike by differentiator 3. Said spike sets a bi-stable 4 which 'set' output closes a switch 6 whereby pulses from a 465 Kc/s. oscillator are gated to a counter 7. By counting up the requisite number of pulses, the counter 7 produces a pulse commencing with the production of said spike and ending 500+0.064Á sec. thereafter. The accuracy figure of 0.064Ás is obtained from a scanned image line being made up of 390 points, each line being scanned (in the absence of a stop due to a detected threshold attainment) in 5 ms., such that each point is scanned in 12.8 ÁS. It is assumed that a maximum of 200 threshold attainments may be detected per line and for a total error time at the end of a line scanning of one point on 12.8 ÁS., the accuracy of the stopping times, i.e. the durations of said pulses, 12.8 must be-= 0.064Ás. This pulse appears at 200 output B and is transmitted to the receiver. Other outputs at C provide, by means of timer 8 and adder 9 and via inverter 10, an input to adder 1, whereby, under the control of the output of discriminator 2, the total signal applied to the discriminator 2 is kept constant during the stopped scan period whereby interference pulses &c. have no effect. Line sync. pulses are added to the transmitted signals, distinguished from the threshold attainment indicating pulses by their greater amplitudes. In the receiver, Fig. 2, the received pulses are fed via interference filter 1<SP>1</SP> and amplifier 2<SP>1</SP> to level discriminators 3<SP>1</SP> and 9<SP>1</SP>, which respectively separate out the line sync. pulses and the threshold attaimment pulses. The former pass to a sync. pulse generator 8<SP>1</SP> and the latter to an assembly comprising switch 6<SP>1</SP>, 465 Kc/s. oscillator 51 and counter 7<SP>1</SP> which, is the same manner as in the transmitter, produce at output C<SP>1</SP> the pulses stopping the reproducing scan thereby indicating a threshold attainment. A two-level image reconstruction is thereby enabled.

Title: Reciprocable hydraulic system
IPC: G06F7/24
Filed: 1972-10-25
Abstract: 1351268 Hydraulic control circuits INTERNATIONAL BUSINESS MACHINES CORP 25 Oct 1972 [22 Dec 1971] 49106/72 Heading F1P [Also in Divison B2] In the arrangement shown in Fig. 1, fluid under pressure is supplied by a pump 16 and a solenoid valve 18 alternately to the undersides of pistons 11, 13, the spaces above the pistons being connected by a line 22, so that as one piston moves up the other is moved down and the pistons are synchronized by adjusting the volume of fluid in the line 22 under the control of means which sense the position of the pistons in the cylinders. The valve 18 is operated by a switch 36 which is magnetically operated by magnetic pieces 38, 40 which reciprocate with the piston 11. Excess fluid is fed back to a reservoir 20 through a valve 24 which is opened when the pistons are not sychronized. The piston strokes are adjustable by altering the positon of the pieces 38, 40, so synchronization is checked at the mid-point of travel by magnetic switches 26, 30. Valve 24 opens when its solenoid is energized. One of switches 26, 30 is normally open and the other closed and change over occurs at the mid-point of piston travel. Any lack of synchronization causes both switches to remain closed until sychronism is restored by fluid passing out of the line 22. Fig. 6 shows an arrangement in which oil may be added to the line 22 by a valve 27 which is controlled by a second pair of contacts, one in each of switches 26, 30. When both these contacts are closed, due to lack of sychronization, fluid is added to line 22 through the valve 27. In a further modification Figs. 8, 9, (not shown), exess fluid is corrected on the upstroke of piston 11 and lack of fluid on the downstroke of piston 11. An electrostatic spray painting disc may be connected to a motor 14.

Abstract: 1471969 Biological cell classification by fluorescence scattering and absorption PARTICLE TECHNOLOGY Inc 28 Nov 1974 [28 Nov 1973 18 Oct 1974] 51594/74 Heading G1A Apparatus 10 for classifying biological cells 28 in a fluid suspension, which are responsive to light by absorption, scattering or fluorescence comprises a laser 12 supplying a multiwavelength beam 13; and means 16 for splitting it into beams 18-24 of different wavelengths, through which cells 28 are caused to flow in flow-cell 26; and photo-cells 30-36 for measuring the cell response to the light. The method of doing this is claimed. 12 can be an argon-ion laser providing wavelengths of 514, 502, 4965, 488, 476À5 and 458 nm. When cells 28 are stained with fluorochromes, secondary fluorescence is detected by photo-cells 30-36, which are coupled to amplifiers 38-44, and can have filters to detect primary fluorescence of the cells at different wavelengths, and can also be used to measure absorption or scattering. Means 48 is a cell separator. In means 50 the cells are formed into charged droplets which are then separated according to their charge by a static field. If a cell is stained with different stains which respond to different wavelengths, an output corresponding to the fluorescence of each can be obtained from detectors 30-36 and the ratios analyzed by computer 46 to classify the cells. An additional single photocell large enough to receive fluorescence due to all of the beams 18-24 may be used. This gives a pulse train as a cell passes the beams. The flowthrough and classification may be continuous.
