Patent GB-975232-A (GB)
Title: Improvements relating to oil heaters
Inventor: BILLETT AUBREY JOHN
IPC: F24C5/08
Filed: 1960-01-26
Abstract: 975,232. Radiant oil stoves; burners. PARKINSON COWAN Ltd. Jan. 26, 1961 [Jan. 26, 1960; March 11, 1960], Nos. 2753/60 and 8597/60. Headings F4T and F4w. A radiant oil heater having a short drum burner 4 extending upwards from an annular kindler trough 7 in front of a reflector 3 comprises means for ensuring that potentially dangerous frontal draughts should either be induced to flow around the kindler trough or should have equal access to the kindler trough and the top of the burner. The lower half of the burner 4 is surrounded by a metal cylinder 13, with an imperforate bottom disc 14 fixed to the outer casing 1. This arrangement ensures that any impinging draught is divided equally between the top of the burner and the kindler trough. To guard against overheating of the trough, holes 16 are punched inwardly in the upper portion of the shield 13, which also has an inwardly-extending flange 18 along its upper edge and a circumferential rib 19, both of which help to prevent fuel spillage when the heater is upset. A perforated diaphragm 20 forms a dome above the inner circle of the kindler trough, closing the bottom of an inner perforated drum 9, and has a further perforated diaphragm 21 above it, with a downturned peripheral flange blocking the lower perforations in the drum 9. These diaphragms serve to prevent " hunting " of the flame from the burner down to the trough.

Title: Method and device for the electrohydraulic or electropneumatic control of roller mills
IPC: B21B13/04
Filed: 1956-01-27
Abstract: 783,676. Pneumatic single-stroke apparatus. BUHLER, GEB. Jan. 27, 1956 [Jan. 28, 1955 ; March 28, 1955], No. 2758/56. Class 8(2). [Also in Group XXIX] In a roller mill having hydraulically loaded rolls, the rolls are released for a predetermined time on the occurrence of excessive pressure due to a foreign body passing between the rolls. At the end of this time if the body remains between the rolls the mill is stopped. Rolls 1 are loaded by pistons 18 in cylinders 13, a pump 2 supplying liquid to the cylinders to load the rolls through a release valve 4, a reversing valve 6, a safety valve 8 and pressure reducing valve 11. On overload the safety valve 8 is actuated and operates a switch 21, closing a circuit through a solenoid 23 which reverses the valve 6 so that liquid is supplied through lines 24 to the cylinders to unload the rolls. A relay 22 maintains the circuit closed after the safety valve has returned to its normal position. After a predetermined time a time delay relay 27 opens a contact 29 to de-energize the solenoid and the valve 6 returns to its initial position. If, within a specified time, overload again occurs due to the body remaining between the rolls, the valve 8 is again actuated. A second relay associated with a time delay relay 27 then breaks the circuit to motors 34, 35 which drive the rolls and the pump. In the embodiment of Fig. 4, a non-return valve 37 is interposed between each reducing valve 11 and its associated cylinder, a relief line 46 with a check valve 47 being provided for each cylinder and permitting escape of liquid from the loading side of the cylinders on reversal of the valve 6 or on the delivery pressure of the pump falling. In another embodiment a safety valve 8 is provided between each valve 11 and its associated cylinder. In another embodiment a single pressure reducing valve 11 is common to all the loading cylinders.

Title: Improvements in or relating to matt colloid layers
Inventor: HART JOHN ALFRED HENRY
IPC: G03C1/95
Filed: 1948-01-30
Abstract: Finely-divided polystyrene resin is incorporated into an aqueous solution of a watersoluble colloid such as gelatine, polyvinyl alcohol, gum arabic or casein, and the solution is coated on to a support and set and dried, to form a matt layer. The finely-divided resin may be added directly to the colloid solution.  Preferably an aqueous dispersion of the finely-divided resin is first formed using a dispersing agent such as the sodium salt of lauryl hydrogen sulphate or of oleyl hydrogen sulphate and is added to the colloid. Four examples describe the production of polystyrene resin-gelatine dispersions.

Title: Improvements relating to the recording of sound
IPC: G11B7/00
Filed: 1944-12-16
Abstract: 574,760. Optical sound recording. KOLB, O. K. Feb. 16, 1944, No. 2873. Drawings to Specification. [Class 40 (ii)] [Also in Group XL] A sound record is made by photographing the trace on the screen of a cathode-ray tube on to a film, tne cathode-ray beam being moved to and fro at supersonic frequency with constant amplitude, but being suppressed at one or both ends of its stroke for intervals which are controlled by the sound to be recorded thereby producing a variable area single or double hump trace on the film. In the arrangement described, a suppressor circuit is employed which is controlled by the sweep voltage so as to operate below a certain threshold value, the threshold being varied in accordance with the sound amplitude. The threshold may also be controlled in accordance with the sound intensity to afford noiseless recording. A multiple track record may be produced by employing a cathode-ray tube emitting two or more beams and a tube having two beams modulated in opposite phases may be employed to afford push-pull tracks.

Title: Improvements in the joining of carbon bodies to other bodies
IPC: C08G16/00
Filed: 1947-02-07
Abstract: A method of making a carbon joint between a carbon body and another carbon or other body having approximately the same coefficient of thermal expansion and the same wettability as the carbon body which method consists in mixing at least 1 cyclic organic compound (having not less than 4 carbon atoms in the ring and a ratio of hydrogen to carbon atoms of about 2 to 1), finely divided carbon and concentrated sulphuric acid with agitation to make a paste, spreading the paste evenly on the joining surfaces, pressing the surfaces together and heating the joint slowly to above 100 DEG C.  Furfural may be used as the organic compound in the paste used to form a joint the joint being heated to between 200 DEG C. and 300 DEG C.  The paste may be made by mixing furfural with finely divided carbon, mixing concentrated sulphuric acid with finely divided carbon and mixing a minor proportion, about 10 per cent, of the second paste with the first paste with vigorous agitation.  After pressing the joined surfaces together the assembly may be allowed to stand at a temperature between 15 DEG C. and 100 DEG C. for a considerable period (e.g. twelve hours or more) before being heated to 200 DEG C. to 300 DEG C.  Alternatively the joint may be heated slowly at between 1/2  DEG C. and 3 DEG C. per minute up to a temperature exceeding 100 DEG C. and maintained at that temperature for about half an hour.

The whole of the roller mechanism, including the bed roll, is mounted so that it can yield bodily to allow for varying thicknesses of work without changing the relative positions of the rollers. As shown in Fig. 2, the feed roller 1 is carried by arms 6 mounted on a slide rest 7, the grip roller 2 is carried by swinging arms 10 turning about the axis of the feed roller, and the supporting grip roller 3 is mounted on a carriage 11 movable longitudinally in dovetail guides in the slide rest. The bed roll 14 is mounted on the carriage 11 so as to move with the supporting grip roller. The movement of the carriage 11 and arms 10 is effected by toggle links 16, 17 and connecting links, 30, the toggle being operated by a crank 19 and connecting rod 18. When the toggle is straightened the bed roll presses the work against the knife cylinder 4, and the feed roller 1 and grip roller 2 engage the work which is supported by the roller 3, the first two rollers 1, 2 engaging the work on the side operated upon by the knife, cylinder. The slide rest 7 is resiliently mounted on the frame of the machine so that, together with the whole of the roller mechanism, it can yield against springs 42, the tension of which can be adjusted by hand-wheels 43. In modifications, the resiliently mounted slide rest and the sliding carriage are replaced by pivoted frames or arms, and the bed roll may be mounted so as to be capable of independent movement.
