Title: Digital plotter
IPC: G01R17/00
Filed: 1965-04-12
Abstract: 1,090,653. Recording apparatus. POTTER INSTRUMENT CO. Inc. April 12, 1965 [April 20, 1964], No. 15404/65. Heading G1J. [Also in Division G4] In printing apparatus for printing both alphanumeric characters and graphs, the graphs are made up of a plurality of dots, using a plurality of printing members each having one or more of the dots positioned on it. In the embodiment described in which printing is effected by hammers 29 (Fig. 1) being selectively energized as a printing drum 21 having 64 axially disposed rows of characters (all characters in a row being the same) is rotated. A row of characters to be printed are read in sequentially on six parallel leads 41 (Fig. 12a) via an input register 43 to a delay line store 45. As the printing drum 21 (Fig. 1) rotates a sensing head 50 reading markings on a disc 49 rotating with the drum 21 supplies pulses to a counter 47, the binary coded output from which is compared in a comparator 57 for each line position of the printing drum with the line of characters stored in the delay line 45. When, for example, the count in counter 47 represents the letter C, whenever an output from the store 45 representing the letter C is applied to the comparator an output pulse is fed by a gate 125 and a matrix 61 under the control of a column counter 99 to registers 59 so that pulses are stored in the stages of the registers 59 corresponding to the columns in which the letter C is to be printed. The next pulse from disc 49 (Fig. 1) causes read out of the registers 59 so that the solenoids controlling the hammers of the printing mechanism are energized to cause the letter C to be printed in the corresponding columns of the paper. When the 64 possible characters on the drum 21 have been compared with the line of characters stored in delay line 45 (Fig. 12) the ribbon advance apparatus 177 is energized and depending on whether alpha-numeric characters or a graph is being printed one of the stages of a flip-flop 141 one for one is enabled to energize one of two clutch driving circuits 151, 155 to rotate the shaft 34 rotating the paper at one of two speeds. The rotation of the shaft is sensed by heads 165, 167 the first pulse from one of which is applied to a flip-flop 145 (Fig. 12) to stop the appropriate clutch driving circuit after the paper has rotated through 1/30th of an inch when graph plotting is occurring and 1/6th of an inch when alpha-numerical characters are being printed.

Title: Mechanical-electrical micro-measurement devices
IPC: G01D5/14
Filed: 1960-05-03
Abstract: 943,967. Hall-effect transducers. AGFA A.G. May 3,1960 [May 20, 1959], No. 15611/60. Heading G1N. A transducer for measuring force or displacement by means of the Hall effect comprises a double magnet having equal and opposite fluxes in the pole gap but a resultant flux in a particular direction outside the gap, and a Hall effect member movable in this direction to develop a potential representative of its displacement from the neutral position. In Fig. 1 a double electromagnet produces equal and opposite fluxes in a polepiece P 1 , and the Hall member B develops zero potential when symmetrically disposed relative to two other polepieces P 2  and P 3  at right angles to P 1 . The Hall member can be placed in the diagonal of a manually rebalanced D.C. or A.C. bridge (Figs 2a and 2b, not shown). Alternatively (Fig. 3), the Hall member HG produces an output which is amplified and applied to a servomotor M which rebalances the bridge at P b . For measuring a force K 1  (Fig. 4), the amplified output from the Hall member HG energizes a servomotor M which rotates a screw S g  to apply an opposing force to a displaceable plate P t  by means of a spring F. The magnitude of the force is read on a scale S k , to which an inkrecorder can be attached.

Abstract: 399,130. Lubricating. LUBRICATION CONTROL CORPORATION, 105, South La Salle Street, Chicago, U.S.A.-(Assignees of Clarke, H. B. ; 900, Lake Shore Drive, Grosse Point, Michigan, U.S.A.) May 31, 1933, Nos. 15702 and 15703. Convention dates, June 7, 1932, and July 30,1932. [Classes 12 (ii) and 12 (iii).] A perforated partition 12 having sloping portions leading to a central oil well 13 is inserted in the oil-pan 11 of an interna!- combustion or like engine, a lubricant pump 19 having its suction opening 20 in the well 13. The perforations 15 in the partition 12 preferably decrease in size towards the well and offer high resistance to the flow therethrough of cold oil. In operation, oil is drawn from the well 13, and after passing to the engine parts drops on to the partition 12. If the oil is cold, it flows down the sloping parts of the partition 12 into the well 13 and is recirculated. As the oil warms up, it flows through the perforations 15 into the pan 11 to increase the pressure head in the latter and force cold oil through holes 16 into the well 13. This action continues till all the oil is warmed. To prevent overheating the oil, pan 11 has air cooling tubes 14 through which air passes as the vehicle carrying the engine moves. The forward end of the tubes 14 may open out into an air scoop. If desired, the pump may also have a suction pipe 21 opening out into the oil pan 11 below the partition 12, and a valve member 22. The latter is connected by linkwork to the engine throttle valve, so that, at slow speeds, the aperture 21 is closed and the passage 20 opened, and at high speeds the aperture 21 is opened and the passage 20 closed. A viscosity meter operating a gauge for visual indication of the oil viscosity may be connected to the pump delivery.

IPC: A42C1/04
Filed: 1929-05-22
Abstract: 326,413. Robinson & Sons (Romiley), Ltd., J., and Sydney, E. May 22, 1929. Blocking; stretching in manufacture.-Soft or hard felt hats are blocked on a movable table actuated by hydraulic power to convev the hat form positioned on its block to the steaming chamber. The steaming chamber e is positioned above a table a provided with vertical guides c and raised by a hydraulic ram in a cylinder l, valves n and o being provided on inlet and exhaust pipes respectively. 'The table is counterbalanced by weights p, and is provided with means for stretching the hat. These comprise a series of clamps each having an upper counterweighted member h pivoted to a lower member h<1> provided with a downwardly projecting pin h<4>. For closing the clamps the edge of the brim, the tails h<2> of the upper members are engaged by a ring h<5> which can be moved through an angle by a handle h<7>, a notch and incline being. formed at the upper edge of the ring for each tail. The lower members h<1> are provided with radial guides and their pins h<4> are each engaged by an inclined slot in a plate which can be moved through an angle by a handle i<2>. A pressure regulating valve (not shown) is provided in the inlet conduit n<2>, which valve is set by the operator in accordance with the particular hat to be treated. In operation, the hat form is heated by a steam jet or by immersion in hot water and placed over a wooden or aluminium block. The edge of the brim is positioned between the clamping jaws, and these closed by manipulation of the handle h<7>. The handle i<2> is then operated to stretch the hat, and a rubber or brass ring is placed on the crown. The ram is then actuated to raise the hat form and block into the steaming chamber. After, say, five seconds treatment, the steam is shut off and the work removed for further flattening of the brim.
Patent GB-158443-A (GB)
Abstract: 158,443. Jones, T. H. Dec. 3, 1919. Circular machines.-Relates to circular knitting machines for making tubular fabrics such as neckties which have a plain or tucked narrow neck part. Certain of the threads supplied are thrown at intervals into the centre of the tube being knitted, and do not then form part of the knitted fabric, which is thus reduced in weight and thickness at the required positions. At the same time the length of the stitches is automatically varied so that a more stretchable and so narrower neck part is made. Certain of the yarns are fed to the needles 1 of a cylinder 2 by means of guides 4 pivoted to standards 5 and adjustably connected to spring-pressed sliding bolts 6 which pass through the table 7 and bear at their lower ends on a ring 8 on which the cylinder 2 is mounted. Bolts 16 projecting from the cams also bear on the ring 8, so that by lowering the ring the guides 4 are thrown out of action, the cylinder 2 is lowered so that the needles draw shorter loops, and the cams 3 are lowered to produce plain fabric, as, for example, for the neckband of a neck-tie &c. This is done by rotating the ring 8 relatively to a ring 9 which supports it, the vertical movement being obtained from co-operating inclines 10 on the rings 8, 9. The ring 8 is shifted by means of a link 34, which is pivoted to the lower end of a swinging arm 30, a roller 32 on which is held against a cam-wheel 27 by a, spring 33. The wheel 27 is moved round by the engagement of dogs 26 on a pattern chain 25 with the cam projections 27<a>. The chain 25 is driven by a ratchet-wheel 23 and pawl 22 from an eccentric disc 17.
