Patent GB-260212-A (GB)
Title: An improved process for the production of a basic copper sulphate suitable for the manufacture of ammoniacal copper oxide cellulose solutions for the spinning of artificial silk by the stretch-spinning process
IPC: C08B1/00
Filed: 1926-06-25
Abstract: 260,212. Bemberg Akt.-Ges., J. P. Oct. 20, 1925, [Convention date]. Ammoniacal-copper cellulose solutions. - A basic copper sulphate of constant composition is prepared by adding sulphuric acid to an ammoniacal copper sulphate solution; the precipitate is washed free from any excess of sulphuric acid or from undecomposed ammoniacal copper sulphate. The product is particularly suitable for the preparation of ammoniacal-copper solutions to be used for dissolving cellulose, the resulting solutions being used for the spinning of artificial silk; the spinning solution contains a constant proportion of sodium sulphate whereby irregularities in the spinning are avoided. In examples, copper hydroxide and cement copper are dissolved in a solution of ammonium sulphate containing ammonia, sulphuric acid being afterwards added to precipitate the basic copper sulphate.

Abstract: 385,211. Glass manufacture. NAAMLOOZE VENNOOTSCHAP MAATSCHAPPIJ TOT BEHEER EN EXPLOITATIE VAN OCTROOIEN, 57, Zeekant, The Hague. June 8, 1932, No. 16174. Convention date, Sept. 26, 1931. [Class 56.] Rolling.-The rollers of an apparatus for producing sheet or plate glass are provided with a shield which covers so much of their surface that the hot glass comes into contact only with those portions of the rolls that are absolutely necessary for forming the glass sheets. The shield protects the rolls from the heat of the glass and deformation of the rolls is minimized. In the construction shown, the upper roller d of a double-roll machine, which comes most into contact with the hot glass, is provided with a shield S which extends over the surface of the roll. A similar shield may be used with the single roll that co-operates with a casting table, and also with the type of apparatus in which a stream of glass flows from a furnace into the pass between a pair of rollers. The shield is preferably made of metal and it may be covered on one or both sides with nonconducting material. Hot or cold air may be passed through the space between the shield and the roll, and the shield may be made hollow and cooled by the circulation of a fluid through its interior. The shield may be made adjustable relatively to, and together with, the rolls.

Abstract: 702,288. Shoots. BERRY, J. R. B., and BERRY, R. A. Oct. 8, 1952 [July 9, 1951], No. 16234/51. Class 78 (1) [Also in Group XXIII] In a brush making machine of the type having two alternative channels for supplying the bristles to the picker, the forward pressure on the bristles is periodically relieved when the picker is not taking the bristle tuft so that they readjust themselves to uniform density. The machine shown comprises two horizontal compartments 7, 8 (Fig. 1) carrying bristles of different length or colour, and pivoted at 42 so that the right hand end of either can be presented to a notched picker bar 2 feeding the tufter 1. The bristles are pressed towards the picker bar by two pins 22 supported respectively on carriages 21 (Fig. 2) connected by chains 39 to weights 41. When the picker bar leaves the bristle compartment slides 26 move to the left and due to the ratchets and pawls 24, 25 carry the carriages with them. A projection 28 on the pawl rides up on an adjustable cam 30 disengaging the pawl and allowing the pins 22 to return thereby imparting a blow to the bristles. The slides are connected by an arcuate bridge 31 and the movement to the left is produced by a roller 33 acting on the bridge and carried either by a bell crank lever 34 operated by a driving linkage or by an elbowed lever operated by an inclined cam nose. The compartments have vertically adjustable bases Fig. 3 (not shown) and the right hand end of each vertical wall carries a forked member 45 which is urged by a spring on to end stops 43, 44 which together with a curved plate 49 hold the bristles in the compartments. According to the Provisional Specification a tuft support platform of adjustable height may be provided beneath the picker. Specification 356,429, [Group XXIII], is referred to.

Title: Electronic business telephone
IPC: H04M11/00
Filed: 1974-04-11
Abstract: 1461978 Displays PLESSEY CO Ltd 11 April 1974 [16 April 1973 7 March 1974] 16370/74 Heading G4H [Also in Division H4] A control for a visual display in a combined electronic calculator/telephone/computer data terminal is arranged to cause numbers to be displayed with blanks between certain groups of digits in response to an indication that the terminal is operating in a telephone mode. Fig. 2 shows a schematic diagram of the complete terminal which utilizes known MOS/LSI circuitry for most of its functions. The description is almost entirely concerned with the operation of the terminal in the telephone mode (see Divisions H3-H5). Fig. 8 shows an articulated display module for displaying a telephone number with blanks separating the different groups of digits making up a telephone number. Processor module supplies the digits over line 28a via a shift control unit 312 to digit shift register 310 and the digits are continuously recirculated through the control units and register. A counter 316 counts the digits supplied by the processor and assuming that the first digit is not 0, 1, or 9 or that the first two digits are not 10 or 01, the detection of the fifth digit causes a blank insert command to be given to the shift control to insert a blank between the 3rd and 4th digits. On detection of the 8th digit a command is given to insert a blank between the 6th and 7th digits. If the first digit is 0 or 1 the counter 316 is arranged to start counting from the second digit unless the digit is 1 or 0 in which case the counting is started on the third digit. An initial 9 is likewise ignored. Digits are displayed as received each digit being fed to the right hand position of the display and being shifted to the left as further digits are fed in. Tables 1-7 (not shown) give examples of the operation for various different initial digits. Should the whole number with the blanks included exceed the capacity of the display, the blanks are automatically removed. Specific circuitry for carrying out the above functions is not disclosed.
