Title: Telephone subset
IPC: H04M1/23
Filed: 1969-09-04
Abstract: 1,242,916. Sets. INTERNATIONAL STANDARD ELECTRIC CORP. 4 Sept., 1969 [11 Sept., 1968; 29 May, 1969], No. 43792/69. Heading H4J. The dial 2 of a telephone set has two or more arcuate recesses 7 each shaped into its underneath and outer cylindrical surfaces and a member 8 extending radially outwards to modify part of each recess 7 into an arcuate groove in the outer cylindrical surface of the dial 2. The subset cover 1 is of plastics material and has a circular opening 4 with two or more integral ribs 3 arranged inside the opening 4 below the cover outer surface. Each rib 3 extends around an arc of, and radially into, the opening 4. The number and spacing of the ribs 3 is the same as the recesses 7. The depth of each rib 3, except for an end stop 6, is such that it will closely fit in the groove portion of each recess 7. The arcuate length of each rib 3 is less than that of each creess 7, but greater than the members 8 in the recesses 7. The dial 2 is mounted in position in the cover 1 by placing the recesses 7 over the ribs 3 and rotating the dial 2 until the members 8 engage under the ribs 3 and against the stops 6 on the ribs 3. A resilient latch 9 extends from the dial into a groove 10 on an inside surface of the cover 1 when the dial 2 is in position. Other additional fixing means are not required.

Title: Character display arrangements

IPC: G09G5/22
Filed: 1970-09-16
Abstract: 1335681 Cathode-ray tube displays PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 16 Sept 1970 [19 Sept 1969] 44273/70 Heading H4T An arrangement for digital data display on a television screen comprises a number of circulating stores (for example using ultrasonic delay lines), one of which holds one row of characters for display and one or more others hold a complete set for the frame display, and transfer of characters to the row store take place during the blank raster lines between successive rows of characters. In Fig. 4 BSp holds all the characters of a display frame, and ZSp a row of characters. The output of clock TK is passed to a series of counters BZ, ZZ, LZ and ZIZ which provide timing outputs for each character period, each scan line, each row of characters and each frame respectively, and HSA and VSA produce horizontal and vertical synchronizing pulses for the display. Date may be entered from a computer via input/output circuit E/A or from a keyboard T, the entry position being held in registers CH, CV which control the generation of a cursor indication (by inverting the display video signal at that position) over comparison circuits V1, V3, AND-gate C and inverter CI, and the entry of the new character into BSp over comparison circuits V1, V2. Transfer from BSp to ZSp is controlled by the outputs of LZ and ZIZ over LD and SSt and the data in ZSp is coded into bright-up signals at ZG which also receives the line count to enable generation of the successive line signals for a single row of characters. The store BSp may be a serial store built up of elements used as line delays in PAL television receivers, or it may consist of a number of individual row recirculating stores using these elements. For shift purposes the effective loop length of the ZSp store may be varied by switching in or out one or two added shift register stages (Fig. 7, not shown). Reference has been directed by the Comptroller to Specification 1,222,265.

Patent GB-1069973-A (GB)
Title: Polymer stabilization
IPC: C08G2/00
Filed: 1963-11-13
Abstract: Oxymethylene polymers containing oxymethylene groups and groups of greater stability are stabilized by subjecting the polymer in solid particulate form to treatment with a liquid medium comprising trioxane together with water and/or an organic hydroxyl compound at a temperature high enough to cause the polymer particles to swell in the liquid medium but too low to cause them to become tacky and so show a tendency to agglomerate. The liquid medium may contain an aldaline material, e.g. ammonia, and less than 40% trioxane. Copolymers, or terpolymers, containing also cyclic ethers are specified, as are oxymethylene homopolymers which have been end-capped with such stable groups as ether groups.

Title: Method and apparatus for predetermining settings for ink fountain keys
IPC: B41F33/00
Filed: 1962-11-28
Abstract: 1,008,087. Selective signalling systems; counters. HARRIS - INTERTYPE CORPORATION. Nov. 28, 1962 [Dec. 1, 1961], No. 44958/62. Headings G4D and G4H. [Also in Divisions G1 and B6] In apparatus for determining the setting of ink fountain keys in a printing press in accordance with the density of parts of the image to be printed, a signal representing ink density is derived photo-electrically and converted to a pulse frequency signal the pulses being counted for a predetermined time. The motor 47, Fig. 7, is driven at a speed indicative of the required ink density. The motor carries a chopper disc or drives some other analogue-to-digital-converter to produce a pulse train having a frequency indicative of the ink density. Switches controlled by the scanning head hold the gate 49 open for a preset time to allow counter 50 to count the pulses. The signal to close gate 49 is differentiated at 90 to produce a pulse to energize a print solenoid 53 and, after delay in a multivibrator 91, a reset counter 54. A scale may be included between gate 49 and counter 50. Construction of counter.-Counting pulses applied to a solenoid 52 rock the lever 57 clockwise so that a pawl 60 pushes the index wheel 61 and printing wheel 56 one step clockwise against a spring 62. A further pawl 63 locks the index wheel while lever 57 returns to its rest position. The print signal energizes a solenoid 53 to actuate a hammer 68 to print the appropriate one of type characters 69 through a ribbon 72 on to a tape 70. A reset pulse applied to the coil 54 moves the rod 64 to the left disengaging pawls 60 and 63 simultaneously. The index and printing wheels are moved anti-clockwise by spring 62 until a stop 67 meets an abutment 68. Abutment 68 also limits the movement of the wheels clockwise.

Abstract: 1,249,546. Photo-electro phoretic imaging. XEROX CORP. Sept. 15, 1969 [Sept. 17, 1968], No. 45319/69. Heading G2H. A method of photo-electrophoretic imaging includes forming a liquid nip of imaging suspension and applying simultaneously an electric field across the nip and imagewise exposing the nip other than through the nip forming surfaces to form an image on at least one of the nip forming surfaces. As shown, an insulating web 1 passes around a conductive roller 3 connected to a D.C. potential. A conductive web 11 passing around a roller 12 connected to a D. C. potential receives imaging suspension from a roller 17 to form a liquid nip at imaging station 19 where the nip is exposed to a light image of a moving document 24. Due to particle migration a positive image is formed on the web 11 which is transferred by pressures or electrostatic force to a copy sheet 27. The insulating web 1 is cleaned of residual pigment particles in a bath 7. In another embodiment, a conductive web (31), Fig.2 (not shown) forms a liquid nip with a roller (33) having a conductive core (34) coated with insulating material 35. Examples of imaging suspensions, insulating and conductive materials are given in the Specification. Specification 1, 124, 625 is referred to.
