Title: Improvements in or relating to knitting and knitted fabrics
IPC: D04B7/04
Filed: 1949-05-25
Abstract: 693,822. Knitting. DUBIED & CIE. SOC. ANON., E. May 25, 1949 [June 3, 1948], No. 14030/49. Class 74 (ii). Patterned fabric, as shown in Fig. 1, is produced on a single bed of a two bed flat machine by feeding yarn to the needles from at least two thread carriers which during their traverse do not cross or pass one another. As described a flat machine has four thread carriers 1 ... 4 each feeding a different yarn, the carriers being mounted on blocks 1<SP>1</SP> ... 4<SP>1</SP> slidable on guide bars 19, 20, two blocks 1<SP>1</SP>, 3<SP>1</SP> and 2<SP>1</SP> 4<SP>1</SP>, being mounted on opposite sides of the guide bars 19 and 20 respectively. Main drivers 9 .. 12 and auxiliary drivers 13, 14 are provided on the double cam locks 7, 8 for both beds of the machine and are adapted to drive the carriers to feed yarns to predetermined needles which are selected to receive the yarns by Jacquard mechanism. Since the needles 18 of one bed only are operative the Jacquard mechanism makes a double selection to enable needles to be operated by the forward or rear stitch cams of the double cam lock movable along that bed. The main drivers 9 ... 12 are positioned on the cam locks so as to enable yarns of the carriers driven by them to be fed to the needles operated by the front or rear stitch cams 8<SP>1</SP>, 8<SP>11</SP> in Fig. 3. Each of the auxiliary drivers 13, 14 is arranged to move a carrier for part of the traverse of the carriage without its yarn being taken by the needles, and thereafter the auxiliary driver is disengaged from the block of the carrier to allow the following main driver, 10 or 12 in Fig. 3 to engage the block during further traverse of the carriage in which period the carrier feeds yarn to selected needles. Ramps 6 are provided at desired intervals to permit the transfer of a carrier driven from an auxiliary driver to a main driver, and stops 5 are provided for disengaging the carriers from the drivers at the end of their traverse. During the reverse movement of the carriage the drivers act in the reverse order.

Title: Improvements in and relating to control devices for fluid-heating installations
Inventor: BRUMMERHOFF WALTER
IPC: F23N1/08
Filed: 1951-06-15
Abstract: 708,125. Controlling fuel-supply. VAILLANT, H., [trading at VAILLANT KOMMANDIT-GES, J.]. June 15, 1951, No. 14184/51. Class 51 (1). [Also in Group XXIX] In an installation in which a fluid flows to a fluid-fuel fired heater through a 'pipe 18 and flows away heated through another pipe 17, e.g. a central heating system in which water is heated in a gas-fired boiler G, a throttle member 9 in the fuel supply to the burner is acted upon by the differential force exerted by opposed bellows 10, 11 which communicate with pilot bulbs 14, 15 thermally connected to the hot-fluid pipe 17 and the cold-fluid pipe 18 respectively and which are in thermal conductive communication with one another by means of a conductor such as a strip 16 of constantan of lower conductivity than copper connections between the bulbs 14, 15 and the pipes 17, 18. Capillary tubes 12, 13 connect the bulbs to the bellows. By this arrangement the difference of temperature between the bulbs tends to be eliminated by the movement of the valve 9 and the heat output of the heater is kept constant since the differential expansion of the bellows depends on the difference between the temperature of the inlet and outlet water and/or on the velocity (and therefore on the quantity) of the water if either or both these values varies or vary. The valve 9 is arranged in a gas circulation duct 7 communicating between spaces above and below a floating disc 5 which, by reason of appended valves 2 which co-act with seats 1 in a gas inlet A, maintains a constant pressure difference between these spaces so that the quantity of gas delivered to the burner is independent of the pressure in the man supply pipe connected to the inlet A and depends entirely on the position of the valve 9. The pilot bulbs are filled with an expanding liquid or partially filled with a volatile liquid. In the latter case, springs 24 on the bellows take up the vapour pressure of the liquid. Springs 22 support the valve 9 and its guiding pin 21 between the opposed bellows 10, 11 but in a modification, Fig. 2 (not shown), the bellows are both mounted to one side of the valve 9 and of its supporting springs and secured each at one end on either side of a fixed plate, the bellows remote from the valve being connected to its respective valve-supporting spring by a bail and being compressed by two further springs in series. One of the springs is depressed only when a certain temperature, determined by an adjustable compressing screw, is reached. In this modification also, the valve 9 is not located between its supporting springs but a plate located in that position is secured to the valve pin. One end of the pin extends beyond the springs, at the end of the assembly remote from the bellows, and bears the valve.

Title: Manufacture of artificial resins
IPC: C08G16/02
Filed: 1930-05-09
Abstract: Ethers.--Neutral oil-soluble resins which may be used as substitutes for natural copal in oil varnishes are obtained by receiving a phenol or a phenolether with a derivative of a polynuclear hydrocarbon containing one or more halogenated methyl groups.  Suitable derivatives of polynuclear hydrocarbons are 1-w-chloromethylnaphthalene, or a mixture of such derivatives obtained by treating a hydrocarbon with a solution of formaldehyde saturated with hydrogen chloride.  The reaction may be carried out in the presence of diluents such as xylene, toluene, chlorobenzene, or a petroleum fraction boiling between 100 DEG  and 200 DEG  C.; when low-boiling diluents are used, pressure may be employed.  Catalysts such as zinc chloride or aluminium chloride may also be present. According to examples (1) a mixture of 1-w-chloromethylnaphthalene with commercial cresol is heated to temperatures rising to 150-160 DEG  C. until the evolution of hydrogen chloride ceases; the product is purified by steam or vacuum distillation.  (2) A dried mixture of a naphthalene derivative containing chloromethyl groups, obtained by treating naphthalene with an aqueous solution of formaldehyde saturated with hydrogen chloride, is reacted with commercial cresol as in (1), and (3) a -methylnaphthalene is chlorinated under conditions favouring the halogenation of side chains, and the produce obtained when one atomic proportion of chlorine has entered the methyl group, after being purified by vacuum distillation, is caused to react with phenol at temperatures rising to 180-190 DEG  C. The resinous product is freed from excess phenol by vacuum distillation.

Title: Improvements in or relating to oscillograph scale systems
IPC: G01R13/20
Filed: 1937-05-28
Abstract: 496,238. Cathode-ray oscillographs; directive wireless signalling. STANDARD TELEPHONES & CABLES, Ltd., CLEAVER, R. F., JAMES, I. R. J., and WAGSTAFFE, C. F. A. May 28, 1937, No. 14848. [Class 37] [Also in Groups XIX and XL] In a cathode-ray oscillograph, for example for use in a radio direction finder, the member on which the scale is marked is separated from the oscillograph screen and the scale is movably associated with the screen so that a reference line on the scale may be adjusted relatively to the screen. As shown in Fig. 1, the scale E is engraved on the back surface of a piece of plate glass G placed in front of and almost touching the end of the tube CRT on which is the screen S. The plate G is illuminated from the edge by a tubular lamp surrounded by a metal reflector R. A black mask extends over the edges of the plate and the engraving is filled with opaque material to prevent light from passing back on to the screen. The plate G may be formed as a planoconcave lens the concave side fitting the end of the cathode-ray tube. In the construction shown in Fig. 3, the scale S<1> is photographed on a sheet of glass FR in clear divisions on a black ground. The scale is illuminated by means of a lamp S and reflector R, the light passing through being reflected by a reflector FG so as to form a virtual image I<1>. The glass plate FR and reflector FG are coated with dyed gelatine to form red and green filters respectively to suppress the reflection of the scale S<1> at the back surface of the reflector FG. Polarizing filters may be used instead of colour filters. In a modification, Fig. 3a, the scale S<1> is photographed on a sheet of glass placed in front of an opal glass O, which is illuminated from behind. A reflector FR causes a virtual image I<1> of the screen to appear on the scale S and is either a red filter or a thinly silvered mirror. In another arrangement, Fig. 4b, a real image of the scale is projected on to the end of the cathode-ray tube CRT from a photographic transparency T<1>. This is produced by making a wooden model of the end of the tube and photographing the scale by means of a camera situated similarly to the lens L" and transparency T<1>. In a modification, Fig. 5, a real image I of the scale is projected on to the end of the tube CRT from a transparency T, a mirror M being interposed at 45‹ to the axis of the tube so that the screen with the image of the scale is viewed horizontally. A lens may be inserted in the aperture in the panel FP. The mirror M is silvered on its front surface and has a number of thin circular concentric slits in its reflecting surface, which permit light from the projector to pass through the mirror without appreciably affecting the quality of the reflection on the oscillograph screen. The North point on the scale is at the top and the cathoderay tube is rotatable on its axis to accommodate any orientation of the directionfinder aerials.
