Title: Manufacture of a liquid crystal device
IPC: G02F1/1337
Filed: 1973-04-02
Abstract: 1388077 Modulating light NCR CORP 2 April 1973 [10 April 1972] 15673/73 Heading H4F [Also in Division C7] The molecules of a nematic liquid crystal phase are aligned parallel, and parallel to a substrate surface, by first vacuum depositing a layer of material on the substrate from a source disposed so that it does not lie on any line extending at 90 degrees from the substrate surface, and then placing the nematic material in contact with the layer. As described, any line connecting the substrate and source should make an angle with the surface normal of 10 to 89À9 degrees, and preferably about 80 degrees. The deposited layer is said to contain parallel oriented anisotropic growths which determine the direction of alignment of the nematic material. The deposited material may be of Pt, Au, Sn, Pb, Al, Cu, Ag, Cr or SiO and have a thickness of 20 Š upwards. The substrate may be electrically insulating, with or without an overlying electrode film, and the deposited layer may be sufficiently thin that it is non-continuous and so electrically non-conductive. Alternatively a thicker deposit on an insulating substrate may act as an electrode film. The layer may be deposited in a pattern for local remote alignment only. In both preferred embodiments, a nematic layer is sandwiched between two substrates having electrodes on their inner surfaces. The thin (non-conductive) layer deposited on one electrode has an alignment direction at 90 degrees to that of the other layer, whereby the cell is optically active in the absence of an electric field and appears isotropic to normally incident light when a field is applied. In a first ease, one electrode forms a selectively operable 7-segment display and the layer is deposited on both that electrode and the revealed substrate surface. In a second case both electrodes are continuous, and the layer on one electrode is deposited in a figure of eight pattern which is only visible between crossed polarizers when a potential difference is not applied between the electrodes.

Title: Improvements in snap-action rotary electric switches
IPC: H01H5/16
Filed: 1963-04-22
Abstract: 1,005,412. Snap-action switches. WALLACETOWN ENGINEERING CO. Ltd., and H. C. IRELAND. April 21, 1964 [April 23, 1963], No. 15708/63. Heading H2B. In a rotary switch of the kind wherein a spring is first strained and then released to provide for snap-action operation of the switch, rotation of a plate 29 fast on a spindle 30 energizes a spring 26 by means of a pin 28 on plate 29, so causing the spring 26 to bias a contact-carrying plate 11 (loosely mounted on the spindle) by means of a pin 14 on plate 11, the plate 11 however being retained against rotation by a fixed locking ring 21, having gap 20 and sunk sectors 22, a plate 18 with lugs 19 located in the gap 20 and a plate 15 having studs 16 engaging holes 18a in plate 18, as the pins 14 from plate 11 are connected to plate 15, and thereby plate 18. Continued rotation of spindle 30 causes a release plate 23a to cam plate 18 out of the gaps 20 in ring 21, via projections 18b on the plate 18, plate 23a being fast with the spindle and moving plate 18 against springs 17, and the plates 18, 15 and 11, rotate quickly as a unit under the action of spring 26, while lugs 19 of plate 18 move over sectors 22 of ring 21 until they abut ends of raised sectors 22a and drop into further gaps 20. Reverse rotation of the spindle re-closes the switch. A manually operable locking device (not shown) locks the spindle in each position by engaging notches 31 in a plate 23 fast with the spindle. If spring 26 fails, then abutments 29a on plate 29 positively rotate the plate 15 via a pin 29b thereon and consequently rotate plate 11 to operate the switch.

A solution of 5 to 50% by weight concentration of a polymer of a #-lactam monosubstituted in the 4-position, the polymer being dissolved in a water-soluble acid is spun into an aqueous coagulation bath and the filaments after they have left the coagulation bath are drawn 3 to 15 times their original length. The temperature of the bath may be 5‹ to 50‹ C. The drawing of the filaments may be effected in water at 50‹ to 90‹ C. The drawn filaments may be heatset in air at 60‹ to 300‹ C. The heat-setting may be effected on a rigid bobbin on which the drawn filaments have been wound. The polymer may have the general formula wherein R, R<1> and R<11> each represent an alkyl group having 1 to 18 carbon atoms, an aryl, aralkyl or cycloalkyl group and R<1> and R<11> may alternatively each represent a hydrogen atom. The polymer solvent may be sulphuric, phosphoric, nitric, acetic, formic, thioglycolic, mono-, di- or trichloro-acetic, trifluoroacetic, lactic, pyroracemic or hydroxyethane sulphonic acid. Concentrated aqueous formic acid is preferred. The ball fall viscosity of the spinning solution at 20‹ C. (DIN Specn. 5401) may be 40 to 800 seconds. The relative viscosity of the polymers, measured in a solution of 1% concentration in concentrated sulphuric acid may be 2 to 300. The coagulating bath may consist of water or an aqueous salt solution of 0À1 to 50% concentration. The salt may be sodium, potassium or zinc chloride, or zinc or sodium sulphate. The filaments may be drawn in water at 5‹ to 100‹ C., preferably 10‹ to 30‹ C., or in air, and may be heat set at 60‹ to 300‹ C. In an example, a solution of 15 parts by weight concentration of poly - 4 - methyl - azetidin - 2 - one (having a relative viscosity of 14À1) in 96% formic acid is splun into an aqueous 16% solution of sodium chloride at 21‹ C. The filament is then drawn to four times its original length in a bath of water at 25‹ C. and heat set under tension by passage over metal plates maintained at 230‹ C.

[Also in Groups XXII and XXV] In a method of forming an external thread in a metal body, e.g. a screw, a high tensile bolt or a stud having a high fatigue resistance, the thread-form inwardly of the pitch cylinder is rolled while the remainder of the thread is freely extruded outwardly beyond the pitch cylinder. A unified thread is formed by dies 36, Fig. 4, with differently-inclined flank portions 40, 44 and a dimension from root 42 to crest 38 greater than that of the thread to be formed. A rolled or coined surface is produced below the pitch-line while metal is freely extruded, i.e. without touching the walls of die cavities 46 to form a portion 47 which may be subsequently ground or otherwise machined to the finished form. In a modification, Fig. 5, a thread form is produced having flank portions 57 with an included angle of 70 degrees and flank portions 59 with an included angle of 60 degrees, this thread being more easily formed with existing machining tools than a 60 degree thread. Prior to threading the blank may be hardened to above 37 Rockwell C and preferably between 42 and 53 Rockwell C to produce a high tensile bolt.

Abstract: 666,656. Electrostatic precipitation. RESEARCH CORPORATION. June 22, 1949 [Nov. 9, 1948], No. 16579/49. Class 39 (i). An electrical precipitator has outside the housing a power-driven travelling carriage which supports a vibrator urged successively into engagement with each of a line of anvils connected with the electrodes, so that the electrodes are successively freed from dust. In one embodiment, Fig. 2, the travelling carriage 29 supports a vibrating shoe 65 which successively rides over the anvils 26. The carriage mounted on wheels 30 is chain-driven back and forth over the track 55. In another embodiment, Fig. 11, a chain-driven carriage 204 travels along the track 203 on wheels 205, and carries a vibrator 206. A vibrating shoe 208 suspended from the vibrator has a longitudinal slot in the bottom, and the edges of the slot provide cam surfaces 210. As the carriage moves along the line of anvils 202 the anvils are successively lifted up by the shoe and vibrated. In a further embodiment, Fig. 5 the carriage 100 is supported from a mono-rail 101 by wheels 102. A motor 109 mounted on the carriage drives a gear segment 120 which periodically engages a rack 121, and a locking- wheel 122 having a peripheral depression 123 in radial alignment with the gear segment 120. As the gear segment 120 engages the rack 121, the carriage 100 is driven along the mono-rail 101. When the carriage arrives at a locking shoe 124 mounted on the underside of the rail 101, the gear segment 120 is disengaged from the rack and the circular periphery of the locking-wheel 122 engages the locking shoe 124 to restrain the carriage from movement along the track. At this moment a stirrup 110 is raised by a cam 129 rotating with the segments 120 and wheel 122. The stirrup 110 has a pair of horizontal members, which engage the underside of the anvil 104 so as to raise it into contact with a vibrator plate 125. The vibrator may operate continuously or may be energized only while the anvil is in contact with the vibrator plate 125. The travel of the carriage is automatically reversed at each end of the track.
