Title: Liquid crystal display devices
IPC: G02F1/1335
Filed: 1973-03-07
Abstract: 1430391 Alpha-numeric displays F HOFFMANN-LA ROCHE & CO AG 7 March 1973 [10 March 1972] 11195/73 Heading G5C [Also in Division H4] Display apparatus comprises a liquid crystal panel between polarizing plates 46, 48 and a reflector 50 comprising a front diffusing surface 52 and a rear reflecting surface 54. The diffusing surface produces a wide viewing angle and reduces unwanted reflections. The panel comprises liquid crystal material between plates 10, 12 carrying electrodes 16... 22, 24... 30. Leads 36 from the electrodes are carried on an extension of plate 10 and form a plug which engages external circuitry. Panels and the liquid crystal material are described in Specifications 1,405,291 and 1,390,522. The electrodes 16... 22 on plate 12 are connected to leads 36A via conductors 40, 42 and conductive resin filling cut-outs 44 in spacer 14. The planes of polarization of plates 46, 48 are at right angles or parallel. The reflector comprises a sheet 50 of transparent glass or plastics material with its front face 52 ground or sandblasted and a reflecting layer of Al, Ni or Cr on its rear surface. The display may be viewed in light from lamps adjacent the edges of sheet 50. Known reflectors of Al 2 O 3 , ceramic, paper and plastics material are referred to.

Title: Improvements in heald operating mechanism for looms
IPC: D03C5/02
Filed: 1927-04-27
Abstract: 294,293. Smith, W. April 27, 1927. Shedding-motions; shedding- tappets.-In order to prevent the damage done to warp threads of very fine cotton, artificial silk, &c., by their crowding together at the time of crossing, two pairs of tappets are employed for tabby or plain weaving, the surfaces of the tappets being so formed that when any two threads cross, they are separated from the adjoining ones. As shown in Fig. 9, tappets 2<a>, 4a acting on bowls w', w<2> of shedding-levers for controlling healds a, c, Fig. 4, carrying warps 2, 4 are shaped so that the tappet 2<a> at its centre x gives a greater lift than that given by the tappet 4a at its centre The warp thread 2 is thereby held above the warp thread 4 throughout the shedding. Similar tappets control healds b, d to maintain the thread 3 above the thread 5. Tappets of the kind shown at 2<a> may be arranged together, or alternate with those of the kind shown at 4a. Strips of fabric of artificial silk may be woven in the manner set out above, the rest of the fabric being woven by a jacquard or dobby.
Patent GB-1470018-A (GB)
Title: Methods of and apparatus for recording information
IPC: G01K1/02
Filed: 1975-03-18
Abstract: 1470018 Recording apparatus SIMRAD AS 18 March 1975 [21 March 1974] 11261/75 Heading G1J Auxiliary data, e.g. temperature, salinity, ocean current velocity, or the catch in a trawl, is recorded on an echo sounder plot as a mark or marks the location of which relative to a reference point is representative of the magnitude of said data, the intensity of the normal echo sounder record being reduced, e.g. to zero, adjacent the mark. Thus, where a series of such marks is recorded to provide a plot of the variation of such data quantity with time or distance, a white or light coloured band is produced adjacent the series of marks to improve the visibility of said auxiliary data record. The auxiliary data, such as temperature, is read into an up-down counter 1 which is counted down to zero when the temperature is to be recorded. When 5 is reached in the count-down, a "5"- detector 5 sends a pulse A to a flip-flop 6 to cause the output C of the latter to go high. This causes the resistance of a controllable resistor 7 to be reduced, to earth the output of an amplifier 4 in the signal path between the echo sounder transducer and the recorder (both not shown), effectively blocking the echo sounder signal. When the count-down reaches zero, a zero detector 2 sends a pulse B to a monostable multi-vibrator 3 so that its output D goes high for a period, to reset the flip-flop 6 so that the resistance of resistor 7 is increased again, the pulse D also passing to the amplifier 4 to cause the recorder to make a strong mark on the chart. The blanked section adjacent the mark may follow the mark instead of preceding it, or may extend on both sides of the mark. An analogue control circuit may be used.

IPC: B21F3/06
Filed: 1962-03-26
Abstract: 929,455. Deforming ends of coil springs. H. FALKNER, W. GEISEL, and E. FALKNER, [trading as HENRY FALKNER KOMM.-GES.]. March 26, 1962 [Dec. 21, 1961], No. 11434/62. Class 83 (4). An arrangement for automatically forming attachment eyes on coil springs includes an eye forming member having a projection which hooks behind the periphery of the first coil turn(s) to be bent into an eye and bends said turn(s) around a stop mounted transversely to the spring axis. Wire 1 fed by rolls 2 is coiled to form a spring by engagement with adjustable stops 3 and is severed by a knife 4. After completion of the first turn(s) of the spring a wedge 8 is moved down behind the end coil 9 and a member 5, extending transversely of the spring axis, is rotated about its own axis so that a hook-like projection 7 thereon engages behind the end coil 9 and bends it over the member 5 so as to form an eye. The member 5 is carried in a holder 10 in an arm 13 rocked in a horizontal plane by.a cam 14 on a driven shaft 12 so as to swing the member 5 in and out of its operative position. The member 5 is turned about its own axis by a pinion actuated by an electromagnet controlled by a contact 19 engaged by a cam projection 15 on the cam 14. After completion the spring is cut off by the knife 4 and drops through a channel 19 into an opening 20 in a horizontally rotated table 21, the formed eye on the end of the spring being received in slots 22 in a second table. The table 21 rotates to carry the spring beneath another eye forming member 5 which forms an eye in the upper end of the spring. Continued movement of the table 21 carries the spring to a discharge position.

Title: Process of treating tars, fuel oils and bitumens
IPC: C10C1/02
Filed: 1936-04-23
Abstract: Lime is incorporated in a heated liquid or semi-solid tar, fuel oil, or bitumen containing tar acids and water under such conditions that at the end of the treatment the free water content of the material is small.  An increase in viscosity probably due to the formation of a gel lattice structure is thus obtained.  The tar acids may be present in the tar as in the case of continuous vertical retort, and low temperature retort tars or they may be added, as e.g. phenol, as in the case of carburetted water gas tar, horizontal retort tar, coke oven tar, bitumen, and fuel oil. The heat may be provided by preheating the tar to, e.g. 70 DEG  C., the heat of reaction sufficing to maintain the temperature.  The proportion of lime may be from 1,6 per cent upwards; one example specifying 20 per cent addition.  The material produced is thixotropic, viz. it loses its rigidity on disturbance but regains it on standing.  The advantages of such a property for fuel oil to be used in the production of "colloidal fuel" is referred to. The treated tar or bitumen may be used as a binder in road construction or in briquetting, or for pipe coatings.ALSO:Lime is incorporated in a heated liquid or semi-solid tar, fuel oil, or bitumen containing tar acids and water such under conditions that at the end of the treatment the free water content of the material is small.

The process may be effected by heating the reaction mixture with agitation at a sufficiently high temperature to cause a steady evolution of CO2.  The aluminium trialkoxide is preferably used in amounts of about 8-25 millimoles. per mol. of acetoacetic ester.  An inert solvent may be present.
