Patent GB-907790-A (GB)
Title: Improvements in or relating to facsimile telegraphy
Inventor: FOLL JOHN VICTOR
IPC: H04N1/191
Filed: 1959-09-16
Abstract: 907,790. Facsimile system. MUIRHEAD & CO. Ltd. July 15, 1960 [Sept. 16, 1959], No. 31585/59. Drawings to Specification. Class 40 (3). In a facsimile system the transmitter and receiver each comprise at least two scanning heads. Each transmitter head scans a different part of the copy and sends signals to a corresponding receiving head. As the signals from the various heads are sent simultaneously, the time of scan of the copy is one half or less of that for the scan if only one head were used. The bandwidth required is increased correspondingly. The several scanning heads at the transmitter and receiver are driven by common lead screws. In order that each strip of reproduction at the receiver shall join the adjacent strips without overlap or gap, the heads are adjustable in their direction of motion over a small range relative to the body of the scanning head carrier, which is moved by the lead screw. The heads are also adjustable to obtain correct registry between the sections of the reproduced copy by movement in a direction perpendicular to the body of the head carrier, Fig. 3 (not shown). It may be arranged that reproduction from one scan head is cut off when it reaches the point where the axially preceding scan head started reproduction. This can be done by counting to certain number of drum revolutions by means of a stepped cam switch, or by means of a slotted disc and photo-cell.

Abstract: 260,439. Tatham, Ltd., W., and Lund, T. Dec. 15, 1925. Carding-engines. - The dividing-roller for a ring doffer condenser is formed of wooden units d turned to the requisite shape so as to bave the grain of the wood at right-angles to the axis of the shaft b. The units d are secured on the shaft b between a fixed flange a and an adjustable flange a'. The outer units have plane faces and are secured to the flanges by screws. The units may be tongued and grooved to interlock and may be keyed to the shaft.
Patent GB-863232-A (GB)
Title: A method and an apparatus for continuous heat-treatment of liquids sensitive to heat
IPC: A23L2/46
Filed: 1958-10-03
Abstract: 863,232. Heat-treating liquids. SEPARATOR A.B. Oct. 3, 1958 [Dec. 11, 1957], No. 31623/58. Class 49. In the continuous heat-treatment of liquids sensitive to heat e.g. the sterilization of milk, in which the liquid is partly vaporized at a temperature below the temperature detrimental to the liquid and the generated vapour is condensed by cooling, the vapour is condensed separately from the liquid, the condensate obtained is heated under raised pressure separately from the liquid and supplied in vapour form to liquid which is to be heat-treated, and that liquid thus heated is cooled rapidly to a temperature below the detrimental temperature. Gases dissolved in the liquid may be removed by subjecting either the liquid before vaporization or the condensate to vacuum. The temperature of milk flowing in a pipe 29 at 65‹ C. is rapidly raised to 135‹ C. by the injection of steam under pressure from a pipe 30 through an injection nozzle 31. The temperature of the milk is then rapidly lowered to 69‹ C. by the reduction of pressure downstream of the valve 33; the cooled, sterilized milk is separated in an expansion vessel 34 from the steam produced. The steam is condensed in a cooler 38; the condensed steam passes to a vessel 40, wherein air and other gases are removed by a vacuum pump 42, and is fed by a pump 43 to a heater 45 for vaporization and injection at the nozzle 31. Heat recovered in the cooler 38 may be supplied to the heater 45. Another arrangement is depicted in Fig. 1 (not shown).

Abstract: 840,757. Filters. GENERAL MOTORS Ltd. Sept. 25, 1958 [Oct. 10, 1957], No. 31688/57. Class 46. [Also in Group XXVIII] Spacing of adjacent pleats 3, Fig. 3, of a filter element 8 of resin impregnated paper folded along lines 2, Fig. 1, to form an annular series of pleats with axially extending fold lines is effected by lines of dimples 4, 6 running parallel to the fold lines. As shown the halves of each pleat 3 are spaced by lines of dimples 5, 7 running parallel to and near the outer and inner fold lines respectively. In a modification, adjacent pleats 11, Fig. 4, are spaced from each other by a single line of dimples 12 near the outer fold lines 14 and the halves of each pleat are spaced by a single line of dimples 15 near the inner fold lines 16. In a further modification, spacing dimples are provided only on alternate halves of the pleats and in a still further modification pleats 30, Fig. 8, are spaced apart near the outer fold lines by lines of abutting dimples 32, 33 and the halves of each pleat are spaced by lines of dimples 35, 36 touching the plane surfaces of the pleats although for convenience is not so shown in the figure. In the above constructions the inner dimples are shallower than the outer ones and the ends of the pleats are secured together by lines of adhesive.

A weft 1 is pushed into a jet picking nozzle 8 by a tube 20 through which air is intermittently ejected to assist in picking. The air through the tube 20 may be the main source of air and may include a droplet of water to wet the weft to prevent unravelling. In Figure 4 the tube 20 is notched at its end where it engages the weft, the main air stream is supplied through its bore, secondary air through the annular gap between the nozzle 8 and tube 20 and the water through a port 27. In Figure 2 air is supplied through an annular gap 14, through the tube 20 when a port 22 coincides with a pipe 23 during the tubes movement and tertiary air is drawn in through a second annular gap 16. In Figure 5 the nozzle cooperates with a suction operated storage tube 7 and, with valves 32, 34 closed by air pressure, air is admitted to chambers 33. When the pressure in feed lines 17a is relieved the pressure of air in the chambers 33 will lift the valves 32 and measured quantities of air will be available for by the nozzle 8 and tube 20 when its port coincides with opening 23. In Figure 1 (not shown) the weft from a reel (2) is supplied to continously rotating feed rolls (3), (4) which pass it to a suction operated storage tube (6) and the combined storage tube and picking nozzle 7.

The humidifier may be controlled by a humidistat P in the box B, and the temperature of the water &c. in the humidifier by a thermostat 237.  The box B consists of a number of open-ended abutting sections E, F slid laterally into C-shaped brackets 33 mounted at intervals on the bed of the knitting machine.  The end sections E may be permanently closed at one end, or loose ends 225 provided with spring clips 227 may be used.  Sliding glass doors 65 at the back and front of each section give access to the yarn packages 68.  Each yarn 69 passes through an eyelet 72 in the box top over one or other of several rails 46, through a liquid trough 48, through a tensioning ring 62 under a "snapper" 57, over one or other of several rails 55 and on to the sinker head &c. assembly S of the knitting or other machine.  The vapour may be blown from near the centre of the box B towards the two ends from nozzles 159, or may be supplied direct from the pipes 153, 154 through short nozzles passing through the bottoms of the several box sections E, F and these nozzles may increase in size the further they are away from the humidifier.  The humidifier comprises a liquid chamber 107 with valve - controlled inlet 217 and overflow pipe 218.  The liquid is drawn up a cone 147 carried by the spindle 143 of a motor M and is then thrown by the disc 146 (also fixed to the motor spindle) against the grid 134 where it is broken up into a spray and then passes up the funnel 117 at the mouth 119 of which it meets air supplied by the fan 104 driven by a motor N.  The motors M, N are controlled by the humidistat P; this consists of a number of horse hairs &c. 193 fixed at one end to an adjustable stud 199 and at the other end to one arm 202 of a lever 184 pivoted at 185 and biassed in one direction by a spring 189.  An arm 186 pivoted at 187 to the lever 184 and steadied relatively thereto by a spring 188 is forked at its upper end to engage the bracket 195 pivoted at 196 and carrying the mercury tube 168 of a mercury switch.
