Title: Improvements relating to the wet spinning of flax
IPC: D01H13/30
Filed: 1944-12-29
Abstract: 579,797. Spinning flax. MACKIE & SONS, Ltd., J., and MACKIE, J. P. Dec. 29, 1944, No. 26111. [Class 120 (iii)] A process for the wet-spinning of flax consists in preparing a roving which is boiled, preferably in alkaline solution, e.g. soda ash or caustic soda, and using the boiled roving on a ring-spinning frame, the roving being formed of the slivers coming from two delivery rollers of the roving frame, wound on a single spindle to constitute a double roving, which, after boiling and drying, is made into a suitable package for use on the ring frame. The rovings may be formed into hanks or skeins before the boiling treatment which treatment may be carried on until, when dry, they have lost between 10-18 per cent. of their original mass due to the pectins &c. removed by the boiling. In an example, the alkaline solution contains 17¢ per cent. caustic soda based on the dry weight of the roving which is boiled therein for 3¢ hours. The process is stated to provide for an increase of 50-100 per cent. in bobbin size spun at a much higher speed. Specification 579,793 is referred to.

Abstract: 813,745. Cooling and protecting reciprocating motors. GOODMANS INDUSTRIES Ltd. Dec. 10, 1956 [Sept. 16, 1955], No. 26624/55. Class 35. [Also in Group XXXVII] In or for a vibrating generating motor having a moving armature coil, a field coil supplied with D.C., and an electrically driven blower inducing forced draught ventilation, such as is disclosed in Specification 795,376, there is provided a sequence control circuit which requires the blower to be switched on before the vibrating motor field and armature coils can be energized and an automatic overheating protection which should the temperature exceed a predetermined value de-energizes, under the control of a temperature-sensitive device, at least the armature coil but leaves the blower running. As shown, the switching requirement is met by arranging that a field coil start push-button P3, whose closure permits energization of the solenoid of a contactor B whose contacts b1 ... b3 are connected in a 3Ph. A.C. supply circuit through a rectifier R to the field coil F, is itself connected to the supply through the holding contact a4 of a contactor A whose contacts a1 ... a3 are connected in the supply circuit to the blower motor M. Hence the field contactor B can be and remain energized only if the blower motor contactor A is closed. The vibration generating motor armature is similarly controlled via a relay C closure of whose contact c3 after closure of the push-button P3 permits energization of another contactor D whose contacts, not shown, control the A.C. supply to the moving coil, not shown. The one or more temperature-sensitive protection devices, not shown, are placed at strategic positions in the motor and each is arranged to close a contact t1, t2 when the temperature exceeds the predetermined value; such closure permits energization of another relay E which opens its contact e1 to de-energize the field and armature controlling contactors B, D while leaving the blower motor M running. Contact e3 maintains relay E energized until, given that the contacts t1, t2 have re-opened, a reset bushbutton P5 is depressed. Other relay contacts c1, c2, e2 cause operation of indicating lamps L1, L2 and a warning lamp L3 and/or alarm bell, not shown.

Title: Improvements in or relating to particulate synthetic resinous moulding materials
Inventor: MANNING WILLIAM REGINALD DERMO
Filed: 1951-11-14
Abstract: 708,028. Cutting sheets of synthetic resin into particles. IMPERIAL CHEMICAL INDUSTRIES, Ltd. Nov. 3, 1952, No. 26654/51. Class 87 (2) Synthetic resin sheet material is divided into particles by subjecting it successively to the nips of two pairs of unheated rolls grooved and registered in such a way that (a) at each nip, each groove on one roll registers with a corresponding groove on the other roll and (b) the scoring on the sheet of heat-softened material caused by the second pair of rolls 13, 14 intersects that caused by the first pair of rolls 11, 12 in such a way that the surfaces of the sheet are divided into small regular areas, allowing the sheet to harden by cooling and then breaking it up along the lines scored by the grooved rolls. The material must be brittle enough to be conveniently broken up, and if it is a thermosetting resin it must be processed when it is still at a heat-softenable stage. The required pattern of scoring is achieved by grooving the rolls 11, 12 circumferentially and the rolls 13, 14 axially. Intermeshing gear wheels may be fixed 'on the ends of the rolls 13, 14 to ensure accurate alignment between the grooves. To obviate sticking of the material to the rolls a comb may be associated with the circumferentially grooved rolls 11, 12 and doctor knives with the axially grooved rolls. The doctor knives are arranged one at each end of each roll 13, 14 with its edge nearest the nip between the rolls at the extremity of the roll and inclined at an angle of 45 degrees to the axis of the roll, extending for about onethird of the length of the roll. The sheet may be scored in a diamond pattern by forming a helical groove on each roll with a 45 degrees helix angle, right-handed, e.g. on the rolls 11, 14 and left-handed on the rolls 12, 13, the crests of the helices registering along the line of the nip. The grooves may have V-shaped or other profiles. The rolls should be cooler than the heat-softened material, but special provision for this need not be made. Some control over the shape of the. particles may be achieved by cooling the sheet with jets of air as it leaves the rolls. With two pairs of rolls as described the process is continuous, but an intermittent process can also be used using only one pair of grooved rolls, the sheet being. passed through the rolls and then turned in the horizontal plane through 90 degrees and passed through once more. The sheet is broken up in two stages, to avoid disintegration of the particles. For the first stage flat blades rotating with a peripheral speed of 1,000 feet per min. may be used, and for the second stage a pin mill rotating at 4,000 r.p.m.

Abstract: 1359635 Radio receivers COMPAGNIE GENERALE DE TELEGRAPHIE SANS FIL 5 Aug 1959 [26 Aug 1958] 26828/59 Heading H3Q In a panoramic reciever which scans a given frequency band, two different, known frequencies are applied to a mixer, the output of which is applied to a second mixer together with the unknown received frequency. The output from the second mixer is amplified and then passed to a bank of filters associated with devices which indicate which filter is conducting. The upper limit of the pass-band of the amplifier following the second mixer is equal to half the lower of the two frequencies applied to the first mixer. The centre frequencies of the passbands of the filters are equally spaced. If a number of receiving circuits of the above type are employed in parallel, then it is shown that a particular arithmetical relationship must exist between the upper frequency limit of the final amplifiers, the pass-band of the receivers and the lower of the two known local frequencies. To avoid errors due to overlapping of the filter pass-bands, the latter may be spaced apart.
